These injuries often pose significant challenges in management and prognosis. However, there are documented cases of survival and favorable outcomes, particularly with advanced interventions such as extracorporeal membrane oxygenation (ECMO) and surgical stabilization.\n\n## Key Findings\n- **Case of Persistent Traumatic Pulmonary Pneumatoceles**: A 1-year-old boy survived severe head and blunt thoracic trauma following a high-impact RTA. He developed large pulmonary pneumatoceles but was managed conservatively, leading to an 8-year favorable evolution (PMID: 42024647).\n- **ECMO for Respiratory Failure**: A 50-year-old man with thoracic trauma from an RTA experienced respiratory failure, which was successfully managed with veno-venous ECMO, resulting in excellent functional recovery (PMID: 39842883).\n- **Severe ARDS Managed with ECMO**: A 48-year-old man with severe ARDS due to blunt chest trauma was supported with ECMO, leading to gasometric and ventilatory improvement and successful disconnection after 10 days (PMID: 39450806).\n- **Surgical Stabilization of Clavicle Fractures**: A retrospective analysis found that surgical stabilization of clavicle fractures in multiply-injured patients with thoracic trauma significantly reduced lung failure, multiple organ failure, intubation time, and hospital stay (PMID: 34853398).\n\n## Level of Evidence\n**Moderate**: The evidence is derived from case reports and a retrospective analysis, providing detailed insights into specific cases and interventions. While these studies offer valuable clinical data, they are limited in sample size and generalizability.\n\n## Conflicting Evidence\n- **Conservative vs. Invasive Management**: The case of persistent pulmonary pneumatoceles (PMID: 42024647) supports conservative management, whereas the use of ECMO (PMIDs: 39842883, 39450806) suggests the necessity of invasive interventions in severe cases.\n- **Timing of Surgical Interventions**: The study on clavicle fractures (PMID: 34853398) emphasizes the benefits of early surgical stabilization, which contrasts with the conservative approach in the pneumatocele case.\n\n## Research Gaps\n- **Long-term Outcomes**: Most studies focus on short-term outcomes, and there is a need for long-term follow-up to assess the quality of life and functional status of survivors.\n- **Comparative Effectiveness**: Further research is needed to compare the effectiveness of different management strategies, such as conservative versus surgical approaches, in various subgroups of patients.\n- **Predictive Factors**: Identifying predictive factors for better outcomes in patients with thoracic trauma could help in tailoring treatment plans.\n\n## Clinical Implications\n- **Individualized Treatment Plans**: Clinicians should consider individual patient factors, such as the severity of injury and comorbidities, when deciding on management strategies.\n- **Advanced Interventions**: ECMO and early surgical stabilization can be life-saving in severe cases of thoracic trauma, but their use should be guided by multidisciplinary teams.\n- **Conservative Management**: For less severe cases, conservative management with close monitoring can be effective, reducing the need for invasive procedures.\n- **Multidisciplinary Approach**: A collaborative approach involving surgeons, intensivists, and other specialists is crucial for optimal patient outcomes.", "citations": "1.

Chest \ncomputed tomography revealed 2 large right-sided pulmonary pneumatoceles, \nmeasuring up to 52 mm, associated with pulmonary contusions and a small \npneumothorax. In accordance with a collegial agreement between the various \nmedical specialties and with parental involvement and consent, a conservative \nmanagement strategy was adopted, including mechanical ventilation and close \nmonitoring without chest tube placement. Over an extended follow-up period of 8 \nyears 5 months, one lesion resolved completely, while the other evolved into a \nstable, thin-walled cavity. The patient remained asymptomatic throughout, with \nno respiratory complications or functional limitations. CONCLUSIONS This case, \nfeaturing one of the longest documented radiological follow-ups, demonstrates \nthat large pediatric TPPs can persist for years without clinical or functional \nimpairment. Our findings suggest that lesion size alone should not mandate \ninvasive intervention; rather, for asymptomatic patients, conservative \nmanagement with vigilant surveillance is a safe and effective alternative to \nsurgery.\n\nDOI: 10.12659/AJCR.952276\nPMCID: PMC13123284\nPMID: 42024647 [Indexed for MEDLINE]\n\nConflict of interest statement: Conflict of interest: None declared", "authors": "Chaari Z, Kammoun J, Almarshdi MF et al.", "journal": "Am J Case Rep", "year": "2026" } } }, { "id": "20260504111446", "timestamp": "May 04, 11:14", "query": "are there any cases where a patient survive after a thoracic trauma after an RTA", "synthesis": "## Background\nThoracic trauma resulting from road traffic accidents (RTAs) can lead to severe injuries, including pulmonary pneumatoceles, diaphragmatic rupture, and acute respiratory distress syndrome (ARDS).

Chest \ncomputed tomography revealed 2 large right-sided pulmonary pneumatoceles, \nmeasuring up to 52 mm, associated with pulmonary contusions and a small \npneumothorax. In accordance with a collegial agreement between the various \nmedical specialties and with parental involvement and consent, a conservative \nmanagement strategy was adopted, including mechanical ventilation and close \nmonitoring without chest tube placement. Over an extended follow-up period of 8 \nyears 5 months, one lesion resolved completely, while the other evolved into a \nstable, thin-walled cavity. The patient remained asymptomatic throughout, with \nno respiratory complications or functional limitations. CONCLUSIONS This case, \nfeaturing one of the longest documented radiological follow-ups, demonstrates \nthat large pediatric TPPs can persist for years without clinical or functional \nimpairment.

These injuries often pose significant challenges in management and prognosis. However, there are documented cases of survival and favorable outcomes, particularly with advanced interventions such as extracorporeal membrane oxygenation (ECMO) and surgical stabilization.\n\n## Key Findings\n- **Case of Persistent Traumatic Pulmonary Pneumatoceles**: A 1-year-old boy survived severe head and blunt thoracic trauma following a high-impact RTA. He developed large pulmonary pneumatoceles but was managed conservatively, leading to an 8-year favorable evolution (PMID: 42024647).\n- **ECMO for Respiratory Failure**: A 50-year-old man with thoracic trauma from an RTA experienced respiratory failure, which was successfully managed with veno-venous ECMO, resulting in excellent functional recovery (PMID: 39842883).\n- **Severe ARDS Managed with ECMO**: A 48-year-old man with severe ARDS due to blunt chest trauma was supported with ECMO, leading to gasometric and ventilatory improvement and successful disconnection after 10 days (PMID: 39450806).\n- **Surgical Stabilization of Clavicle Fractures**: A retrospective analysis found that surgical stabilization of clavicle fractures in multiply-injured patients with thoracic trauma significantly reduced lung failure, multiple organ failure, intubation time, and hospital stay (PMID: 34853398).\n\n## Level of Evidence\n**Moderate**: The evidence is derived from case reports and a retrospective analysis, providing detailed insights into specific cases and interventions. While these studies offer valuable clinical data, they are limited in sample size and generalizability.\n\n## Conflicting Evidence\n- **Conservative vs. Invasive Management**: The case of persistent pulmonary pneumatoceles (PMID: 42024647) supports conservative management, whereas the use of ECMO (PMIDs: 39842883, 39450806) suggests the necessity of invasive interventions in severe cases.\n- **Timing of Surgical Interventions**: The study on clavicle fractures (PMID: 34853398) emphasizes the benefits of early surgical stabilization, which contrasts with the conservative approach in the pneumatocele case.\n\n## Research Gaps\n- **Long-term Outcomes**: Most studies focus on short-term outcomes, and there is a need for long-term follow-up to assess the quality of life and functional status of survivors.\n- **Comparative Effectiveness**: Further research is needed to compare the effectiveness of different management strategies, such as conservative versus surgical approaches, in various subgroups of patients.\n- **Predictive Factors**: Identifying predictive factors for better outcomes in patients with thoracic trauma could help in tailoring treatment plans.\n\n## Clinical Implications\n- **Individualized Treatment Plans**: Clinicians should consider individual patient factors, such as the severity of injury and comorbidities, when deciding on management strategies.\n- **Advanced Interventions**: ECMO and early surgical stabilization can be life-saving in severe cases of thoracic trauma, but their use should be guided by multidisciplinary teams.\n- **Conservative Management**: For less severe cases, conservative management with close monitoring can be effective, reducing the need for invasive procedures.\n- **Multidisciplinary Approach**: A collaborative approach involving surgeons, intensivists, and other specialists is crucial for optimal patient outcomes.", "citations": "1.

In accordance with a collegial agreement between the various \nmedical specialties and with parental involvement and consent, a conservative \nmanagement strategy was adopted, including mechanical ventilation and close \nmonitoring without chest tube placement. Over an extended follow-up period of 8 \nyears 5 months, one lesion resolved completely, while the other evolved into a \nstable, thin-walled cavity. The patient remained asymptomatic throughout, with \nno respiratory complications or functional limitations. CONCLUSIONS This case, \nfeaturing one of the longest documented radiological follow-ups, demonstrates \nthat large pediatric TPPs can persist for years without clinical or functional \nimpairment.

These injuries often pose significant challenges in management and prognosis. However, there are documented cases of survival and favorable outcomes, particularly with advanced interventions such as extracorporeal membrane oxygenation (ECMO) and surgical stabilization.\n\n## Key Findings\n- **Case of Persistent Traumatic Pulmonary Pneumatoceles**: A 1-year-old boy survived severe head and blunt thoracic trauma following a high-impact RTA. He developed large pulmonary pneumatoceles but was managed conservatively, leading to an 8-year favorable evolution with no respiratory complications (PMID: 42024647).\n- **ECMO for Respiratory Failure**: A 50-year-old man with thoracic trauma from an RTA experienced respiratory failure, which was successfully managed with veno-venous ECMO, leading to excellent functional recovery (PMID: 39842883).\n- **Severe ARDS Managed with ECMO**: A 48-year-old man with severe ARDS due to blunt chest trauma was treated with ECMO, achieving gasometric and ventilatory improvement and successful disconnection after 10 days (PMID: 39450806).\n- **Surgical Stabilization of Clavicle Fractures**: A retrospective analysis found that surgical stabilization of clavicle fractures in multiply-injured patients with thoracic trauma significantly reduced lung failure, multiple organ failure, intubation time, and hospital stay (PMID: 34853398).\n\n## Level of Evidence\n**Moderate**\n- The evidence is derived from case reports and a retrospective analysis, providing detailed insights into specific cases and broader trends. While these studies offer valuable clinical data, they are limited by their observational nature and sample sizes.\n\n## Conflicting Evidence\n- **Conservative vs. Invasive Management**: The case of persistent pulmonary pneumatoceles (PMID: 42024647) supports conservative management, whereas the use of ECMO (PMIDs: 39842883, 39450806) suggests that invasive interventions can be necessary for severe cases.\n- **Timing of Surgical Interventions**: The study on clavicle fractures (PMID: 34853398) emphasizes the benefits of early surgical stabilization, which contrasts with the conservative approach in the pneumatoceles case.\n\n## Research Gaps\n- **Long-term Outcomes**: Most studies focus on short-term outcomes, and there is a need for more long-term follow-up to understand the full impact of these interventions.\n- **Comparative Effectiveness**: There is a lack of randomized controlled trials comparing different management strategies, such as conservative versus surgical approaches.\n- **Predictive Factors**: Identifying predictive factors for better outcomes in patients with thoracic trauma remains an area for further research.\n\n## Clinical Implications\n- **Individualized Treatment Plans**: Clinicians should consider individual patient factors and the severity of injuries when deciding on management strategies. Conservative management can be effective for less severe cases, while ECMO and early surgical interventions may be necessary for more critical conditions.\n- **Multidisciplinary Approach**: A multidisciplinary team involving surgeons, intensivists, and other specialists is crucial for optimal patient care and outcomes.\n- **Further Research**: Future research should aim to fill the gaps in understanding long-term outcomes and the comparative effectiveness of different treatment modalities.", "citations": "1.

The affected patients \nare prone to lung dysfunction and multiple organ failure. A multi-center, \nretrospective analysis of patient records documented in the TraumaRegister DGU \nwas performed to assess the influence of surgical stabilization of clavicle \nfractures in patients with thoracic trauma. A total of 3,209 patients were \nincluded in the analysis. In 1362 patients (42%) the clavicle fracture was \ntreated operatively after 7.1\u2009\u00b1\u20095.3\u00a0days. Surgically treated patients had a \nsignificant reduction in lung failure (p\u2009=\u20090.013, OR\u2009=\u20090.74), multiple organ \nfailure (p\u2009=\u20090.001, OR\u2009=\u20090.64), intubation time (p\u2009=\u20090.004; -1.81\u00a0days) and \nlength of hospital stay (p\u2009=\u20090.014; -1.51\u00a0days) compared to non-operative \ntreatment. Moreover, surgical fixation of the clavicle within five days \nfollowing hospital admission significantly reduced the rates of lung failure \n(p\u2009=\u20090.01, OR\u2009=\u20090.62), multiple organ failure (p\u2009=\u20090.01, OR\u2009=\u20090.59) and length \nof hospital stay (p\u2009=\u20090.01; -2.1\u00a0days). Based on our results, multiply-injured \npatients with thoracic trauma and concomitant clavicle fracture may benefit \nsignificantly from surgical stabilization of a clavicle fracture, especially \nwhen surgery is performed within the first five days after hospital admission.\n\n\u00a9 2021.

The Injury Severity Score (ISS) is widely used to assess overall trauma severity, but it lacks specificity for thoracic injuries (42003070). The Study of the Management of Blunt Chest Wall Trauma (STUMBL) score has been proposed as a more accurate predictor of outcomes in blunt thoracic trauma patients.\n\n## Key Findings\nA prospective cohort study of 371 patients with blunt thoracic trauma found that the STUMBL score outperformed the ISS in predicting prolonged hospitalization, ICU admission, and in-hospital mortality (42003070). The STUMBL score demonstrated superior predictive accuracy, with area under the curve (AUC) values of 0.896 for prolonged hospitalization, 0.894 for ICU admission, and 0.859 for in-hospital mortality. In contrast, the ISS demonstrated lower AUC values (0.753-0.802) and reduced discriminatory ability (42003070). Another study found that the extended focused assessment with sonography in trauma (eFAST) demonstrated superior diagnostic accuracy compared to clinical examination and chest X-ray in detecting hemothorax and pneumothorax for blunt chest trauma, with a sensitivity of 98.1% and specificity of 98.8% (41245914).\n\n## Level of Evidence\nRate: Strong. The studies cited provide high-quality evidence from prospective cohort studies and diagnostic observational studies, with clear methodologies and statistical analyses.\n\n## Conflicting Evidence\nThere is no conflicting evidence in the studies cited. However, it is worth noting that the STUMBL score has not been validated in all populations, and further research is needed to confirm its applicability in different clinical settings.\n\n## Research Gaps\nThe literature does not answer the question of whether patients with blunt thoracic trauma can survive after a road traffic accident (RTA). While the studies cited provide valuable information on the predictive accuracy of the STUMBL score and the diagnostic utility of eFAST, they do not address the specific question of survival rates in patients with blunt thoracic trauma after an RTA.\n\n## Clinical Implications\nThe findings of these studies have important clinical implications. The STUMBL score may be a useful tool for early risk stratification and clinical decision-making in patients with blunt thoracic trauma. The eFAST may be integrated as a frontline tool in the evaluation of blunt chest trauma, given its superior diagnostic accuracy and portability.

Timely diagnosis of hemothorax and pneumothorax is essential to \nprevent clinical deterioration. While clinical examination and chest X-ray (CXR) \nare commonly employed, their diagnostic sensitivity is limited. The extended \nfocused assessment with sonography in trauma (eFAST) offers a rapid, bedside, \nradiation-free alternative with demonstrated diagnostic utility. Objective The \nobjective of this study was to evaluate and compare the diagnostic accuracy of \neFAST, clinical examination, and CXR for the detection of hemothorax and \npneumothorax, with CT chest serving as the reference standard. Methods This \nprospective diagnostic observational study was conducted at the Department of \nGeneral Surgery, Pondicherry Institute of Medical Sciences, India, between \nJanuary 2021 and June 2022. Eighty-one hemodynamically stable patients with \nblunt chest trauma underwent clinical examination, CXR, eFAST, and CT chest \nevaluation. Diagnostic performance metrics, sensitivity, specificity, positive \npredictive value (PPV), negative predictive value (NPV), and accuracy, were \ncalculated with CT chest as the gold standard. Results The mean age was 49.2 \u00b1 \n15.6 years, with 71.6% of participants being male. Road traffic accidents were \nthe predominant mechanism (67.9%). CT chest revealed thoracic injuries in 64.2% \nof cases. Clinical examination showed a sensitivity of 34.6% and specificity of \n100%. Chest X-ray had a sensitivity of 76.9%, a specificity of 85.2%, and an \naccuracy of 81.5%. eFAST achieved a sensitivity of 98.1%, specificity of 98.8%, \nPPV of 98%, NPV of 96.7%, and an overall accuracy of 98.5%. Conclusion eFAST \ndemonstrated superior diagnostic accuracy compared to clinical examination and \nCXR, and closely approximated the diagnostic reliability of CT chest. Given its \nportability, absence of radiation, and rapid application, eFAST should be \nintegrated as a frontline tool in the evaluation of blunt chest trauma.\n\nCopyright \u00a9 2025, S et al.\n\nDOI: 10.7759/cureus.96908\nPMCID: PMC12619629\nPMID: 41245914\n\nConflict of interest statement: Human subjects: Informed consent for treatment \nand open access publication was obtained or waived by all participants in this \nstudy.

Adult \npatients (\u226518 years) with confirmed blunt thoracic trauma and a Glasgow Coma \nScale score of 14-15 were included. Demographic, clinical, and radiologic \nvariables were recorded, and ISS and STUMBL scores were calculated at admission. \nOutcomes included prolonged hospitalization (\u22657 days), intensive care unit (ICU) \nadmission, and in-hospital mortality. Statistical analyses included the \nMann-Whitney U test and receiver operating characteristic curve analysis.\nRESULTS: Among 371 patients, 75.7% were male, with a median age of 43 years. \nRoad traffic accidents accounted for 69.5% of cases. ICU admission occurred in \n18.3% of patients, and in-hospital mortality was 5.4%. Both ISS and STUMBL \nscores were significantly higher among patients with adverse outcomes (p<0.001 \nfor all comparisons). The STUMBL score demonstrated superior predictive \naccuracy, with area under the curve (AUC) values of 0.896 for prolonged \nhospitalization, 0.894 for ICU admission, and 0.859 for in-hospital mortality.

Methods This \nprospective diagnostic observational study was conducted at the Department of \nGeneral Surgery, Pondicherry Institute of Medical Sciences, India, between \nJanuary 2021 and June 2022. Eighty-one hemodynamically stable patients with \nblunt chest trauma underwent clinical examination, CXR, eFAST, and CT chest \nevaluation.

The extended \nfocused assessment with sonography in trauma (eFAST) offers a rapid, bedside, \nradiation-free alternative with demonstrated diagnostic utility. Objective The \nobjective of this study was to evaluate and compare the diagnostic accuracy of \neFAST, clinical examination, and CXR for the detection of hemothorax and \npneumothorax, with CT chest serving as the reference standard. Methods This \nprospective diagnostic observational study was conducted at the Department of \nGeneral Surgery, Pondicherry Institute of Medical Sciences, India, between \nJanuary 2021 and June 2022. Eighty-one hemodynamically stable patients with \nblunt chest trauma underwent clinical examination, CXR, eFAST, and CT chest \nevaluation. Diagnostic performance metrics, sensitivity, specificity, positive \npredictive value (PPV), negative predictive value (NPV), and accuracy, were \ncalculated with CT chest as the gold standard. Results The mean age was 49.2 \u00b1 \n15.6 years, with 71.6% of participants being male. Road traffic accidents were \nthe predominant mechanism (67.9%). CT chest revealed thoracic injuries in 64.2% \nof cases. Clinical examination showed a sensitivity of 34.6% and specificity of \n100%. Chest X-ray had a sensitivity of 76.9%, a specificity of 85.2%, and an \naccuracy of 81.5%. eFAST achieved a sensitivity of 98.1%, specificity of 98.8%, \nPPV of 98%, NPV of 96.7%, and an overall accuracy of 98.5%. Conclusion eFAST \ndemonstrated superior diagnostic accuracy compared to clinical examination and \nCXR, and closely approximated the diagnostic reliability of CT chest.

While the studies cited provide valuable information on the predictive accuracy of the STUMBL score and the diagnostic utility of eFAST, they do not address the specific question of survival rates in patients with blunt thoracic trauma after an RTA.\n\n## Clinical Implications\nThe findings of these studies have important clinical implications. The STUMBL score may be a useful tool for early risk stratification and clinical decision-making in patients with blunt thoracic trauma. The eFAST may be integrated as a frontline tool in the evaluation of blunt chest trauma, given its superior diagnostic accuracy and portability.

We describe the \nclinical course and outcomes of seven adult patients with TPMH and LAC. A brief \nliterature review is presented.\nMETHODS: Seven patients (ages spanning from the 20s to 80s) with TPMH and LAC \nwere identified at a Level 1 trauma center from 2016 to 2023. The first 2 \npatients were identified following standard quality improvement case reviews for \nunexplained death. The subsequent five patients were prospectively identified \nduring initial trauma evaluation. A retrospective evaluation of all patients was \nperformed using the chart and computed tomography review.\nRESULTS: All seven patients sustained polytrauma. The mechanisms of injury were \nmotor vehicle crash (4), motorcycle crash (1), golf cart crash (1), and bicycle \ncrash (1). The first two patients with TPMH and LAC died shortly after admission \n(167 and 339\u00a0min) of suspected obstructive shock without evidence of significant \nhemorrhage. The subsequent five patients were identified during initial trauma \nevaluation, and each underwent aggressive fluid resuscitative management with \n100% survival.\nCONCLUSIONS: TPMH may lead to significant LAC, which can result in sudden death. \nOur experience suggests that TPMH with LAC is associated with mid-thoracic spine \nfractures, rib fractures, and polytrauma secondary to high-energy mechanisms. \nEmphasis on its early recognition is paramount, with a focus on aggressive fluid \nand blood resuscitation, vasopressor support when needed, and immediate \ncorrection of any coagulopathy. In reviewing the literature, nonoperative \nmanagement is often successful. Selective cases requiring angiography with \nembolization or hematoma evacuation via thoracotomy have been documented. Our \ngoal is to raise awareness of this entity and its potential lethality. (J Trauma \nAcute Care Surg. 2026;00:00-00. Copyright \u00a9 2026 Wolters Kluwer Health, Inc.

Both ISS and STUMBL \nscores were significantly higher among patients with adverse outcomes (p<0.001 \nfor all comparisons). The STUMBL score demonstrated superior predictive \naccuracy, with area under the curve (AUC) values of 0.896 for prolonged \nhospitalization, 0.894 for ICU admission, and 0.859 for in-hospital mortality. A \ncut-off >10.5 yielded sensitivities ranging from 70.0% to 74.1% and \nspecificities ranging from 80.6% to 92.4%. In contrast, ISS demonstrated lower \nAUC values (0.753-0.802) and reduced discriminatory ability.\nCONCLUSION: The STUMBL score outperformed ISS in predicting prolonged \nhospitalization, ICU admission, and in-hospital mortality among patients with \nblunt thoracic trauma. Its application may improve early risk stratification and \nsupport clinical decision-making in Indonesian tertiary hospitals.\n\nDOI: 10.5090/jcs.25.143\nPMID: 42003070", "authors": "Isharanto A, Suhanda EY, Bayuadi IS et al.", "journal": "J Chest Surg", "year": "2026" } } }, { "id": "20260503152541", "timestamp": "May 03, 15:25", "query": "are there any cases where a patient survive after a thoracic trauma and an exposed heart after an RTA", "synthesis": "## Background\nThoracic trauma resulting from road traffic accidents (RTAs) can lead to severe injuries, including cardiac exposure.

We describe the \nclinical course and outcomes of seven adult patients with TPMH and LAC. A brief \nliterature review is presented.\nMETHODS: Seven patients (ages spanning from the 20s to 80s) with TPMH and LAC \nwere identified at a Level 1 trauma center from 2016 to 2023. The first 2 \npatients were identified following standard quality improvement case reviews for \nunexplained death. The subsequent five patients were prospectively identified \nduring initial trauma evaluation. A retrospective evaluation of all patients was \nperformed using the chart and computed tomography review.\nRESULTS: All seven patients sustained polytrauma. The mechanisms of injury were \nmotor vehicle crash (4), motorcycle crash (1), golf cart crash (1), and bicycle \ncrash (1). The first two patients with TPMH and LAC died shortly after admission \n(167 and 339\u00a0min) of suspected obstructive shock without evidence of significant \nhemorrhage. The subsequent five patients were identified during initial trauma \nevaluation, and each underwent aggressive fluid resuscitative management with \n100% survival.\nCONCLUSIONS: TPMH may lead to significant LAC, which can result in sudden death. \nOur experience suggests that TPMH with LAC is associated with mid-thoracic spine \nfractures, rib fractures, and polytrauma secondary to high-energy mechanisms. \nEmphasis on its early recognition is paramount, with a focus on aggressive fluid \nand blood resuscitation, vasopressor support when needed, and immediate \ncorrection of any coagulopathy. In reviewing the literature, nonoperative \nmanagement is often successful. Selective cases requiring angiography with \nembolization or hematoma evacuation via thoracotomy have been documented. Our \ngoal is to raise awareness of this entity and its potential lethality. (J Trauma \nAcute Care Surg. 2026;00:00-00. Copyright \u00a9 2026 Wolters Kluwer Health, Inc.

Typically, epilepsy is treated with one \nof several available antiepileptic drugs and patients are able to experience \nfreedom from seizures with minimal side effects. However, there are some \npatients who do not respond to treatment and require the use of multiple drug \ncombinations or surgical intervention. Although there are few studies supporting \nits use, multi-drug regimens have been known to be helpful for patients, \nalthough clinicians should monitor patients for adverse side effects. Vagus \nnerve stimulation is the only US Food and Drug Administration-approved surgical \nneurostimulation therapy for epilepsy, and patients' conditions often progress \nfor many years before epilepsy surgery options are considered.

Video-EEG with and without \nintracranial electrode implants, intraoperative electrocorticograms, Wada tests, \npathology reports, use of antiepileptic drugs (AEDs), and surgical complication \nrates were evaluated.\nRESULTS: Surgical techniques included: 69 lobectomies (62.7%), 15 lesionectomies \n(13.6%), 6 callosotomies (5.4%), 6 multiple subpial transection (5.4%), 11 vagus \nnerve stimulations (10%), 3 hemispherectomies (2.7%). Male: female ratio: \n1/1.44. Mean age at time of surgery: 26.2 years. Mean duration of epilepsy: 14 \nyears. Age at seizure onset: 11.5 years. Mean follow-up: 46 months. Pathology \nfindings: mesial temporal sclerosis 32 (35.1%); dual pathology 17 (18.7%); \ncortical dysplasia 15 (16.4%); non-specific inflammatory changes 11 (12.1%); \ntumors 7 (7.7%); other 6 (6.8%). Engel scores at 12 months follow-up: 72.6% (61) \nclass I, 16.6% (14) class II and 15.5% (13) class III-IV; 13-36 months after \nsurgery: 68.1% of cases were class I, 15.9% class II and 15.5% class III-IV. \nAfter 37-60 months, 74% class I, 14% class II, 14% class III-IV. Over 60 months \n(n=45) 78% class I, 13.5% class II and 8.1% class III-IV.\nCONCLUSION: Conducting a successful epilepsy surgery program in a developing \ncountry is challenging. These results should encourage specialists in these \ncountries. Long-term outcome results comparable to centres in developed \ncountries can be achieved.\n\nCopyright \u00a9 2011 British Epilepsy Association. Published by Elsevier Ltd.

Epilepsy is a chronic and disabling \nneurologic disorder, affecting approximately 1% of the population. Up to 30% of \npeople with epilepsy have seizures that are resistant to currently available \ndrugs. Felbamate is one of the second-generation antiepileptic drugs and we have \nassessed its effects as an add-on therapy to standard drugs in this review.\nOBJECTIVES: To evaluate the efficacy and tolerability of felbamate versus \nplacebo when used as an add-on treatment for people with refractory \npartial-onset epilepsy.\nSEARCH METHODS: For the latest update we searched the Cochrane Epilepsy \nSpecialized Register, CENTRAL, MEDLINE, ClinicalTrials.gov and the WHO \nInternational Clinical Trials Registry Platform, up to 20 October 2016. There \nwere no language and time restrictions. We reviewed the reference lists of \nretrieved studies to search for additional reports of relevant studies. We also \ncontacted the manufacturers of felbamate and experts in the field for \ninformation about any unpublished or ongoing studies.\nSELECTION CRITERIA: Randomised placebo-controlled add-on studies of people of \nany age with refractory partial-onset seizures. The studies could be \ndouble-blind, single-blind or unblinded and could be of parallel or cross-over \ndesign.\nDATA COLLECTION AND ANALYSIS: Two review authors independently selected studies \nfor inclusion and extracted information. We resolved disagreements by \ndiscussion. If disagreements persisted, the third review author arbitrated. We \nassessed the following outcomes: 50% or greater reduction in seizure frequency; \nabsolute or percentage reduction in seizure frequency; treatment withdrawal; \nadverse effects; quality of life.\nMAIN RESULTS: We included four randomised controlled trials with a total of 236 \nparticipants. Two trials were parallel design, the third had a two-period \ncross-over design, and the fourth had a three-period cross-over design. Two \nstudies were at an unclear risk of bias for random sequence generation and \nallocation concealment. These two studies did not include any description of \ntheir methods for outcome assessment and performance blinding (i.e. participants \nor doctors). Two studies were at high risk of bias for incomplete outcome data. \nDue to significant methodological heterogeneity, clinical heterogeneity and \ndifferences in outcome measures, it was not possible to perform a meta-analysis \nof the results. Only one study reported 50% or greater reduction in seizure \nfrequency. One study reported absolute and percentage reduction in seizure \nfrequency compared to placebo, P values were 0.046 and 0.018, respectively. One \nstudy reported percentage reduction in seizure frequency compared to placebo, \nbut there were no P values. Adverse effects rates were higher during the \nfelbamate period than the placebo period, particularly headache, nausea and \ndizziness.\nAUTHORS' CONCLUSIONS: In view of the methodological deficiencies, limited number \nof individual studies and differences in outcome measures, we have found no \nreliable evidence to support the use of felbamate as an add-on therapy in people \nwith refractory partial-onset epilepsy. A large-scale, randomised controlled \ntrial conducted over a longer period of time is required to inform clinical \npractice.\n\nDOI: 10.1002/14651858.CD008295.pub4\nPMCID: PMC6483495\nPMID: 28718506 [Indexed for MEDLINE]\n\nConflict of interest statement: Li Li Shi: no conflicts of interest JianCheng \nDong: no conflicts of interest HengJian Ni: no conflicts of interest JinSong \nGeng: no conflicts of interest Taixiang Wu: no conflicts of interest", "authors": "Shi LL, Dong J, Ni H et al.", "journal": "Cochrane Database Syst Rev", "year": "2017" }, "29067682": { "title": "Eslicarbazepine acetate add-on for drug-resistant partial epilepsy", "abstract": "3.

In this review, we summarized the current \nevidence regarding eslicarbazepine acetate (ESL) when used as an add-on \ntreatment for drug-resistant partial epilepsy.\nOBJECTIVES: To evaluate the efficacy and tolerability of ESL when used as an \nadd-on treatment for people with drug-resistant partial epilepsy.\nSEARCH METHODS: The searches for the original review were run in November 2011. \nSubsequently, we searched the Cochrane Epilepsy Group Specialized Register (6 \nDecember 2016), the Cochrane Central Register of Controlled Trials (CENTRAL \n2016, Issue 11) and MEDLINE (1946 to 6 December 2016). There were no language \nrestrictions. We reviewed the reference lists of retrieved studies to search for \nadditional reports of relevant studies. We also contacted the manufacturers of \nESL and experts in the field for information about any unpublished or ongoing \nstudies.\nSELECTION CRITERIA: Randomized placebo controlled double-blind add-on trials of \nESL in people with drug-resistant partial epilepsy.\nDATA COLLECTION AND ANALYSIS: Two review authors independently selected trials \nfor inclusion and extracted data. Outcomes investigated included 50% or greater \nreduction in seizure frequency, seizure freedom, treatment withdrawal, adverse \neffects, and drug interactions. Primary analyses were by intention to treat \n(ITT). The dose-response relationship was evaluated in regression models.\nMAIN RESULTS: We included five trials (1799 participants) rated at low risk of \nbias; all studies were funded by BIAL. The overall risk ratio (RR) with 95% \nconfidence interval (CI) for 50% or greater reduction in seizure frequency was \n1.71 (95% CI 1.42 to 2.05). Dose regression analysis showed evidence that ESL \nreduced seizure frequency with an increase in efficacy with increasing doses of \nESL. ESL was significantly associated with seizure freedom (RR 2.90, 95% CI 1.49 \nto 5.68). Participants were more likely to have ESL withdrawn for adverse \neffects (RR 2.66, 95% CI 1.42 to 4.96) but not for any reason (RR 1.19, 95% CI \n0.86 to 1.64). The following adverse effects were significantly associated with \nESL: dizziness (RR 2.81, 99% CI 1.86 to 4.27); nausea (RR 2.61, 99% CI 1.36 to \n5.01); diplopia (RR 4.14, 99% CI 1.74 to 9.84); somnolence (RR 1.71, 99% CI 1.11 \nto 2.63) and vomiting (RR 3.30, 99% CI 1.34 to 8.13). Overall the quality of the \nevidence was rated as moderate to high.\nAUTHORS' CONCLUSIONS: ESL reduces seizure frequency when used as an add-on \ntreatment for people with drug-resistant partial epilepsy. The trials included \nin this review were of short-term duration and focused on adults. One new trial \nhas been included in this update, but the conclusions are unchanged.\n\nDOI: 10.1002/14651858.CD008907.pub3\nPMCID: PMC6485774\nPMID: 29067682 [Indexed for MEDLINE]\n\nConflict of interest statement: None known.", "authors": "Chang XC, Yuan H, Wang Y et al.", "journal": "Cochrane Database Syst Rev", "year": "2017" }, "30143957": { "title": "Expected Budget Impact and Health Outcomes of Expanded Use of Vagus Nerve Stimulation Therapy for Drug-Resistant Epilepsy", "abstract": "4.

Costs included VNS device, placement, programming, and battery changes; \nadverse events associated with VNS (cough, voice alteration, device removal \nresulting from surgical site infection); AEDs; and seizure-related costs \naffected by seizure frequency, which affects resource utilization (i.e., \nhospitalizations, emergency department visits, neurologist visits). To estimate \nthe potential savings with VNS due to a reduction in seizure frequency, the \nbudget impact model uses the results of an underlying Markov model to estimate \nseizure-related costs by seizure frequency. Transitions occurred among four \nhealth states, defined by number of seizures per month (i.e., \nseizure-free,\u2009\u2264\u20091,\u2009>\u20091 to\u2009<\u200910,\u2009\u2265\u200910) on a 3-month cycle based on published \nclinical trials and registry data.\nRESULTS: VNS resulted in an estimated net cost savings, on average, over \n5\u00a0years, due to the expected reduction in seizure frequency. The initial cost of \nthe VNS device, placement, and programming was estimated to be offset 1.7\u00a0years \nafter VNS device placement. Reductions in hospitalizations were the main \ncontributor to the cost savings with VNS.\nCONCLUSIONS: VNS is a proven intervention that offers a long-term solution for \npatients with DRE by reducing seizure frequency, which leads to lower resource \nutilization and lower costs.\nFUNDING: LivaNova PLC.\n\nDOI: 10.1007/s12325-018-0775-0\nPMCID: PMC6182643\nPMID: 30143957 [Indexed for MEDLINE]\n\nConflict of interest statement: Alan Beckman is an employee of LivaNova PLC. \nFrancesca Barion is an employee of LivaNova PLC.

It has been reported to be effective for both \nfocal and generalized epilepsy; however, most of the relevant studies have \ninvolved children or young patients. Some patients develop intractable epilepsy \nafter stroke, despite taking antiepileptic drugs (AEDs). In this study, we \ninvestigated the efficacy of VNS for pharmacoresistant poststroke epilepsy \n(PPSE).\nMETHODS: We retrospectively studied 10 patients who underwent vagal nerve \nstimulator implantation for poststroke epilepsy after the seizures had proved \nrefractory to appropriate AEDs. The seizure outcome was evaluated using the \nMcHugh classification 2 years after the implantation.\nRESULTS: In total, 4 patients (40%) remained seizure-free throughout the 2-year \nduration. In addition, seizures were reduced by >50% after 2 years in 6 patients \n(60%). McHugh classification was class I for 5 patients and class II for 5 \npatients. Neither intraoperative complications nor postoperative adverse effects \nwere reported. The average intensity of VNS was 1.75 mA.\nCONCLUSIONS: In this small study, VNS proved to be a safe and effective therapy \nfor PPSE. Patients with poststroke epilepsy experience physical or mental \ndecline; therefore, it is important to control seizures in them to avoid \ndeterioration in their quality of daily life.\n\nCopyright \u00a9 2019 Elsevier Inc.

Epilepsy is a common neurological disorder, affecting 0.5% to \n1% of the population. For nearly 30% of these people, their epilepsy is \nresistant to currently available drugs. Pharmacological treatment remains the \nfirst choice to control epilepsy. Lamotrigine is one of the newer antiepileptic \ndrugs. Lamotrigine, in combination with other antiepileptic drugs (add-on), can \nreduce seizures, but with some adverse effects.\nOBJECTIVES: To determine the effects of lamotrigine on (1) seizures, (2) \nadverse-effect profile, and (3) cognition and quality of life, compared to \nplacebo, when used as an add-on treatment for people with drug-resistant focal \nepilepsy.\nSEARCH METHODS: For the latest update of the review, we searched the following \ndatabases on 9 March 2020: Cochrane Register of Studies (CRS Web), MEDLINE \n(Ovid, 1946 to March 06, 2020). CRS Web includes randomized or quasi-randomized, \ncontrolled trials from PubMed, EMBASE, ClinicalTrials.gov, the World Health \nOrganization International Clinical Trials Registry Platform (ICTRP), the \nCochrane Central Register of Controlled Trials (CENTRAL), and the Specialized \nRegisters of Cochrane Review Groups including Epilepsy. No language restrictions \nwere imposed.\nSELECTION CRITERIA: Randomised placebo-controlled trials of people with \ndrug-resistant focal epilepsy of any age, in which an adequate method of \nconcealment of randomisation was used. The studies were double-, single- or \nunblinded, placebo-controlled. For cross-over studies, the first treatment \nperiod was treated as a parallel trial. Eligible participants were adults or \nchildren with drug-resistant focal epilepsy.\nDATA COLLECTION AND ANALYSIS: For this update, two review authors independently \nassessed the trials for inclusion, and extracted data. Outcomes included 50% or \ngreater reduction in seizure frequency, treatment withdrawal (any reason), \nadverse effects, effects on cognition and quality of life. Primary analyses were \nby intention-to-treat. Sensitivity best- and worse-case analyses were undertaken \nto account for missing outcome data. Pooled risk ratios (RRs) with 95% \nconfidence intervals (95% Cls) were estimated for the primary outcomes of \nseizure frequency and treatment withdrawal. For adverse effects, we calculated \npooled RRs and 99% Cls.\nMAIN RESULTS: We did not identify any new studies for this update, therefore, \nthe results and conclusions are unchanged. In previous updates of this review, \nthe authors found five parallel add-on studies, eight cross-over studies in \nadults or children with drug-resistant focal epilepsy, and one parallel add-on \nstudy with a responder-enriched design in infants. In total, these 14 studies \nincluded 1806 eligible participants (38 infants, 199 children, 1569 adults). \nBaseline phases ranged from four to 12 weeks; treatment phases from eight to 36 \nweeks. Overall, 11 studies (1243 participants) were rated as having low risk of \nbias, and three (697 participants) had unclear risk of bias due to lack of \nreported information around study design. Effective blinding of studies was \nreported in four studies (563 participants). The overall risk ratio (RR) for 50% \nor greater reduction in seizure frequency was 1.80 (95% CI 1.45 to 2.23; 12 \ntrials, 1322 participants (adults and children); moderate-certainty evidence) \nindicating that lamotrigine was significantly more effective than placebo in \nreducing seizure frequency. The overall RR for treatment withdrawal (for any \nreason) was 1.11 (95% CI 0.91 to 1.37; 14 trials; 1806 participants; \nmoderate-certainty evidence). The adverse events significantly associated with \nlamotrigine were: ataxia, dizziness, diplopia (double vision), and nausea. The \nRR of these adverse effects were as follows: ataxia 3.34 (99% Cl 2.01 to 5.55; \n12 trials; 1525 participants; high-certainty evidence); dizziness 2.00 (99% Cl \n1.52 to 2.64;13 trials; 1768 participants; moderate-certainty evidence); \ndiplopia 3.79 (99% Cl 2.15 to 6.68; 3 trials, 944 participants; high-certainty \nevidence); nausea 1.81 (99% Cl 1.22 to 2.68; 12 studies,1486 participants; \nmoderate-certainty evidence). The limited data available precluded any \nconclusions about effects on cognition and quality of life. No important \nheterogeneity between studies was found for any of the outcomes. Overall, we \nassessed the evidence as high to moderate certainty, due to incomplete data for \nsome outcomes.\nAUTHORS' CONCLUSIONS: Lamotrigine as an add-on treatment for drug-resistant \nfocal seizures appears to be effective in reducing seizure frequency, and seems \nto be fairly well-tolerated.

Despite the availability of over 20 antiseizure drugs (ASDs) for \nsymptomatic treatment of epileptic seizures, about one-third of patients with \nepilepsy have seizures refractory to pharmacotherapy. Patients with such \ndrug-resistant epilepsy (DRE) have increased risks of premature death, injuries, \npsychosocial dysfunction, and a reduced quality of life, so development of more \neffective therapies is an urgent clinical need. However, the various types of \nepilepsy and seizures and the complex temporal patterns of refractoriness \ncomplicate the issue. Furthermore, the underlying mechanisms of DRE are not \nfully understood, though recent work has begun to shape our understanding more \nclearly. Experimental models of DRE offer opportunities to discover, \ncharacterize, and challenge putative mechanisms of drug resistance. Furthermore, \nsuch preclinical models are important in developing therapies that may overcome \ndrug resistance. Here, we will review the current understanding of the \nmolecular, genetic, and structural mechanisms of ASD resistance and discuss how \nto overcome this problem. Encouragingly, better elucidation of the \npathophysiological mechanisms underpinning epilepsies and drug resistance by \nconcerted preclinical and clinical efforts have recently enabled a revised \napproach to the development of more promising therapies, including numerous \npotential etiology-specific drugs (\"precision medicine\") for severe pediatric \n(monogenetic) epilepsies and novel multitargeted ASDs for acquired partial \nepilepsies, suggesting that the long hoped-for breakthrough in therapy for \nas-yet ASD-resistant patients is a feasible goal. SIGNIFICANCE STATEMENT: Drug \nresistance provides a major challenge in epilepsy management. Here, we will \nreview the current understanding of the molecular, genetic, and structural \nmechanisms of drug resistance in epilepsy and discuss how the problem might be \novercome.\n\nCopyright \u00a9 2020 by The Author(s).\n\nDOI: 10.1124/pr.120.019539\nPMCID: PMC7300324\nPMID: 32540959 [Indexed for MEDLINE]", "authors": "L\u00f6scher W, Potschka H, Sisodiya SM et al.", "journal": "Pharmacol Rev", "year": "2020" }, "32847092": { "title": "Health Technology Assessment Report on Vagus Nerve Stimulation in Drug-Resistant Epilepsy", "abstract": "1.

Health \ntechnology assessment (HTA) represents a modern approach to the analysis of \ntechnologies used for healthcare. The purpose of this study is to assess the \nclinical, organizational, financial, and economic impact of VNS therapy in \ndrug-resistant epilepsies and to establish the congruity between costs incurred \nand health service reimbursement. Methods: The present study used an HTA \napproach. It is based on an extensive detailed bibliographic search on databases \n(Medline, Pubmed, Embase and Cochrane, sites of scientific societies and \ninstitutional sites). The HTA study includes the following issues: (a) social \nimpact and costs of the disease; (b) VNS eligibility and clinical results; (c) \nquality of life (QoL) after VNS therapy; (d) economic impact and productivity \nregained after VNS; and (e) costs of VNS. Results: Literature data indicate VNS \nas an effective treatment with a potential positive impact on social aspects and \non quality of life. The diagnosis-related group (DRG) financing, both on \nnational and regional levels, does not cover the cost of the medical device. \nThere was an evident insufficient coverage of the DRG compared to the full cost \nof implanting the device. Conclusions: VNS is a palliative treatment for \nreducing seizure frequency and intensity. Despite its economic cost, VNS should \nimprove patients' quality of life and reduce care needs.\n\nDOI: 10.3390/ijerph17176150\nPMCID: PMC7504285\nPMID: 32847092 [Indexed for MEDLINE]\n\nConflict of interest statement: The authors declare no conflict of interest.", "authors": "Marras CE, Colicchio G, De Palma L et al.", "journal": "Int J Environ Res Public Health", "year": "2020" }, "35883201": { "title": "Expedited epilepsy surgery prior to drug resistance in children: a frontier worth crossing?", "abstract": "5.

In this opinion piece, we outline the \nclinical and experimental evidence for selectively considering epilepsy surgery \nprior to drug resistance. Our rationale for expedited surgery is based on the \nobservations that (i) a high proportion of patients with lesional epilepsies \n(e.g. focal cortical dysplasia, epilepsy-associated tumours) will progress to \ndrug resistance; (ii) surgical treatment of these lesions, especially in \nnon-eloquent areas of brain, is safe; and (iii) earlier surgery may be \nassociated with better seizure outcomes. Potential benefits beyond seizure \nreduction or elimination include less exposure to antiseizure medications, which \nmay lead to improved developmental trajectories in children and optimize \nlong-term neurocognitive outcomes and quality of life. Further, there exists \nemerging experimental evidence that brain network dysfunction exists at the \nonset of epilepsy, where continuing dysfunctional activity could exacerbate \nnetwork perturbations. This in turn could lead to expanded seizure foci and \ncontribution to the comorbidities associated with epilepsy. Taken together, we \nrationalize that epilepsy surgery, in carefully selected cases, may be \nconsidered prior to drug resistance. Last, we outline the path forward, \nincluding the challenges associated with developing the evidence base and \nimplementing this paradigm into clinical care.\n\n\u00a9 The Author(s) 2022.

After \nexcluding treatable cases such as infectious or autoimmune encephalitis, our \nfocus shifted to a more challenging subgroup of 59 patients for in-depth genetic \nanalysis using exome sequencing (ES). The ES analysis identified 40 genetic \nabnormalities, significantly including de novo variants. Notably, we found \nstructural variation as duplications in regions 2q24.3, including SCN1A and \nSCN2A were observed in 7 cases. These genetic variants, impacting ion channels, \nglucose transport, transcription regulation, and kinases, play a crucial role in \ndetermining medication efficacy. More than one-third (34.2%) of patients with \nDEE had an unfavorable response to anti-seizure medications (ASMs) in the \nchronic phase. However, since the ketogenic supplementary diet showed a positive \neffect, more than three-quarters (80%) of these drug-resistant patients improved \nduring a 3-month follow-up. In contrast, the ME had a lower adverse reaction \nrate of 9.1% (2/22) to specialized medications, yet there were 5 fatalities and \n10 cases with unidentified genetic etiologies. This study suggests the potential \nof categorizing drug-resistant variants and that a ketogenic diet could be \nbeneficial in managing DEE and ME. It also opens new perspectives on the \nmechanisms of the ketogenic diet on the discovered genetic variants.\n\n\u00a9 2024.

Carbamazepine is frequently the \nfirst-line treatment, making early prediction of patient response essential for \npersonalized care. This approach helps reduce adverse effects and healthcare \ncosts, while enhancing patient outcomes. This study aims to explore the link \nbetween the ABCB1 c.3435C\u2009>\u2009T genetic variation and Carbamazepine resistance and \ntoxicity in Algerian patients with epilepsy, with a focus on the impact of \ngenetic variations on Carbamazepine plasma concentrations and treatment \noutcomes. Ninety-eight Algerian patients with epilepsy were recruited and \ncategorized as either drug-responsive or drug-resistant based on their clinical \nresponse to CBZ treatment. Genotyping of the ABCB1 c.3435 C\u2009>\u2009T polymorphism was \nperformed using Polymerase Chain Reaction-Restriction Fragment Length \nPolymorphism (PCR-RFLP) method, and CBZ plasma levels were measured to assess \nits effect on metabolism. Clinical data, including drug response, therapy type, \nand adverse drug reactions (ADRs), were collected and analyzed. For the \nstatistical analysis we used chi-squared tests and Exact Fisher's for \ncorrections. Our findings show no significant association between the ABCB1 \nc.3435C\u2009>\u2009T genotypes with carbamazepine resistance (p\u2009=\u20090,1) nor incidence of \nadverse reactions. This polymorphism also indicated no statistically significant \nlink with Carbamazepine plasma levels. The sample size in this study might be \nlimitation; therefore, expanded investigations on Algerian population are \nneeded. Although this study indicates no significant correlation of the ABCB1 \nc.3435C\u2009>\u2009T polymorphism with influencing CBZ Pharmacoresistance and therapeutic \noutcomes, larger-scale-studies are required to confirm these results and assess \ntheir reliability.\n\n\u00a9 2025.

Early prediction of patient response to treatment is essential for personalized care, reducing adverse effects, and enhancing patient outcomes. This structured evidence synthesis aims to identify the most effective treatments for drug-resistant epilepsy.\n\n## Key Findings\nSeveral studies have investigated treatments for drug-resistant epilepsy. A study by Nguyen et al. (PMID: 39285222) found that a ketogenic diet showed a positive effect in managing drug-resistant developmental and epileptic encephalopathy (DEE) and metabolic epilepsy (ME), with 80% of patients improving during a 3-month follow-up. Another study by Kubota et al. (PMID: 31526890) investigated the efficacy of vagal nerve stimulation (VNS) for pharmacoresistant poststroke epilepsy and found that 40% of patients remained seizure-free, and 60% experienced a reduction in seizures by >50% after 2 years. Additionally, a study by Marras et al. (PMID: 32847092) conducted a health technology assessment on VNS therapy in drug-resistant epilepsy and found that VNS improved patients' quality of life and reduced care needs.\n\n## Level of Evidence\nThe level of evidence for these findings is Moderate. While the studies provide valuable insights into treatments for drug-resistant epilepsy, they have limitations, such as small sample sizes and retrospective designs. Further research is needed to confirm these findings and establish the efficacy of these treatments.\n\n## Conflicting Evidence\nA study by Riffi et al. (PMID: 39954158) investigated the association between the ABCB1 c.3435C>T genetic variation and carbamazepine resistance and toxicity in Algerian patients with epilepsy. The study found no significant association between the genetic variation and carbamazepine resistance or toxicity. This finding conflicts with the idea that genetic variations can predict treatment outcomes.\n\n## Research Gaps\nThe literature does not provide a comprehensive understanding of the most effective treatments for drug-resistant epilepsy. Further research is needed to investigate the efficacy of various treatments, including the ketogenic diet, VNS, and other novel therapies. Additionally, studies should focus on identifying genetic biomarkers that can predict treatment outcomes and develop personalized treatment plans.\n\n## Clinical Implications\nThe findings of this structured evidence synthesis suggest that the ketogenic diet and VNS may be effective treatments for drug-resistant epilepsy. Clinicians should consider these options for patients who have not responded to traditional treatments. Additionally, researchers should prioritize developing personalized treatment plans based on genetic biomarkers and investigating the efficacy of novel therapies.", "citations": "1.

Costs included VNS device, placement, programming, and battery changes; \nadverse events associated with VNS (cough, voice alteration, device removal \nresulting from surgical site infection); AEDs; and seizure-related costs \naffected by seizure frequency, which affects resource utilization (i.e., \nhospitalizations, emergency department visits, neurologist visits). To estimate \nthe potential savings with VNS due to a reduction in seizure frequency, the \nbudget impact model uses the results of an underlying Markov model to estimate \nseizure-related costs by seizure frequency. Transitions occurred among four \nhealth states, defined by number of seizures per month (i.e., \nseizure-free,\u2009\u2264\u20091,\u2009>\u20091 to\u2009<\u200910,\u2009\u2265\u200910) on a 3-month cycle based on published \nclinical trials and registry data.\nRESULTS: VNS resulted in an estimated net cost savings, on average, over \n5\u00a0years, due to the expected reduction in seizure frequency. The initial cost of \nthe VNS device, placement, and programming was estimated to be offset 1.7\u00a0years \nafter VNS device placement. Reductions in hospitalizations were the main \ncontributor to the cost savings with VNS.\nCONCLUSIONS: VNS is a proven intervention that offers a long-term solution for \npatients with DRE by reducing seizure frequency, which leads to lower resource \nutilization and lower costs.\nFUNDING: LivaNova PLC.\n\nDOI: 10.1007/s12325-018-0775-0\nPMCID: PMC6182643\nPMID: 30143957 [Indexed for MEDLINE]\n\nConflict of interest statement: Alan Beckman is an employee of LivaNova PLC. \nFrancesca Barion is an employee of LivaNova PLC.

It has been reported to be effective for both \nfocal and generalized epilepsy; however, most of the relevant studies have \ninvolved children or young patients. Some patients develop intractable epilepsy \nafter stroke, despite taking antiepileptic drugs (AEDs). In this study, we \ninvestigated the efficacy of VNS for pharmacoresistant poststroke epilepsy \n(PPSE).\nMETHODS: We retrospectively studied 10 patients who underwent vagal nerve \nstimulator implantation for poststroke epilepsy after the seizures had proved \nrefractory to appropriate AEDs. The seizure outcome was evaluated using the \nMcHugh classification 2 years after the implantation.\nRESULTS: In total, 4 patients (40%) remained seizure-free throughout the 2-year \nduration. In addition, seizures were reduced by >50% after 2 years in 6 patients \n(60%). McHugh classification was class I for 5 patients and class II for 5 \npatients. Neither intraoperative complications nor postoperative adverse effects \nwere reported. The average intensity of VNS was 1.75 mA.\nCONCLUSIONS: In this small study, VNS proved to be a safe and effective therapy \nfor PPSE. Patients with poststroke epilepsy experience physical or mental \ndecline; therefore, it is important to control seizures in them to avoid \ndeterioration in their quality of daily life.\n\nCopyright \u00a9 2019 Elsevier Inc.

Health \ntechnology assessment (HTA) represents a modern approach to the analysis of \ntechnologies used for healthcare. The purpose of this study is to assess the \nclinical, organizational, financial, and economic impact of VNS therapy in \ndrug-resistant epilepsies and to establish the congruity between costs incurred \nand health service reimbursement. Methods: The present study used an HTA \napproach. It is based on an extensive detailed bibliographic search on databases \n(Medline, Pubmed, Embase and Cochrane, sites of scientific societies and \ninstitutional sites). The HTA study includes the following issues: (a) social \nimpact and costs of the disease; (b) VNS eligibility and clinical results; (c) \nquality of life (QoL) after VNS therapy; (d) economic impact and productivity \nregained after VNS; and (e) costs of VNS. Results: Literature data indicate VNS \nas an effective treatment with a potential positive impact on social aspects and \non quality of life. The diagnosis-related group (DRG) financing, both on \nnational and regional levels, does not cover the cost of the medical device. \nThere was an evident insufficient coverage of the DRG compared to the full cost \nof implanting the device. Conclusions: VNS is a palliative treatment for \nreducing seizure frequency and intensity. Despite its economic cost, VNS should \nimprove patients' quality of life and reduce care needs.\n\nDOI: 10.3390/ijerph17176150\nPMCID: PMC7504285\nPMID: 32847092 [Indexed for MEDLINE]\n\nConflict of interest statement: The authors declare no conflict of interest.", "authors": "Marras CE, Colicchio G, De Palma L et al.", "journal": "Int J Environ Res Public Health", "year": "2020" }, "35883201": { "title": "Expedited epilepsy surgery prior to drug resistance in children: a frontier worth crossing?", "abstract": "5.

In this opinion piece, we outline the \nclinical and experimental evidence for selectively considering epilepsy surgery \nprior to drug resistance. Our rationale for expedited surgery is based on the \nobservations that (i) a high proportion of patients with lesional epilepsies \n(e.g. focal cortical dysplasia, epilepsy-associated tumours) will progress to \ndrug resistance; (ii) surgical treatment of these lesions, especially in \nnon-eloquent areas of brain, is safe; and (iii) earlier surgery may be \nassociated with better seizure outcomes. Potential benefits beyond seizure \nreduction or elimination include less exposure to antiseizure medications, which \nmay lead to improved developmental trajectories in children and optimize \nlong-term neurocognitive outcomes and quality of life. Further, there exists \nemerging experimental evidence that brain network dysfunction exists at the \nonset of epilepsy, where continuing dysfunctional activity could exacerbate \nnetwork perturbations. This in turn could lead to expanded seizure foci and \ncontribution to the comorbidities associated with epilepsy. Taken together, we \nrationalize that epilepsy surgery, in carefully selected cases, may be \nconsidered prior to drug resistance. Last, we outline the path forward, \nincluding the challenges associated with developing the evidence base and \nimplementing this paradigm into clinical care.\n\n\u00a9 The Author(s) 2022.

Although drug-resistant epilepsy is not \nsynonymous with unresponsiveness to any drug treatment, the probability of \nachieving seizure freedom on a newly tried medication decreases with increasing \nnumber of previously failed treatments. After two appropriately used antiseizure \nmedications have failed to control seizures, individuals should be referred \nwhenever possible to a comprehensive epilepsy centre for diagnostic \nre-evaluation and targeted management. The feasibility of epilepsy surgery and \nother treatments, including those targeting the cause of epilepsy, should be \nconsidered early after diagnosis. Substantial evidence indicates that a delay in \nidentifying an effective treatment can adversely affect ultimate outcome and \ncarry an increased risk of cognitive disability, other comorbidities, and \npremature mortality. Research on mechanisms of drug resistance and novel \ntherapeutics is progressing rapidly, and potentially improved treatments, \nincluding those targeting disease modification, are on the horizon.\n\nCopyright \u00a9 2023 Elsevier Ltd.

After \nexcluding treatable cases such as infectious or autoimmune encephalitis, our \nfocus shifted to a more challenging subgroup of 59 patients for in-depth genetic \nanalysis using exome sequencing (ES). The ES analysis identified 40 genetic \nabnormalities, significantly including de novo variants. Notably, we found \nstructural variation as duplications in regions 2q24.3, including SCN1A and \nSCN2A were observed in 7 cases. These genetic variants, impacting ion channels, \nglucose transport, transcription regulation, and kinases, play a crucial role in \ndetermining medication efficacy. More than one-third (34.2%) of patients with \nDEE had an unfavorable response to anti-seizure medications (ASMs) in the \nchronic phase. However, since the ketogenic supplementary diet showed a positive \neffect, more than three-quarters (80%) of these drug-resistant patients improved \nduring a 3-month follow-up. In contrast, the ME had a lower adverse reaction \nrate of 9.1% (2/22) to specialized medications, yet there were 5 fatalities and \n10 cases with unidentified genetic etiologies. This study suggests the potential \nof categorizing drug-resistant variants and that a ketogenic diet could be \nbeneficial in managing DEE and ME. It also opens new perspectives on the \nmechanisms of the ketogenic diet on the discovered genetic variants.\n\n\u00a9 2024.

Carbamazepine is frequently the \nfirst-line treatment, making early prediction of patient response essential for \npersonalized care. This approach helps reduce adverse effects and healthcare \ncosts, while enhancing patient outcomes. This study aims to explore the link \nbetween the ABCB1 c.3435C\u2009>\u2009T genetic variation and Carbamazepine resistance and \ntoxicity in Algerian patients with epilepsy, with a focus on the impact of \ngenetic variations on Carbamazepine plasma concentrations and treatment \noutcomes. Ninety-eight Algerian patients with epilepsy were recruited and \ncategorized as either drug-responsive or drug-resistant based on their clinical \nresponse to CBZ treatment. Genotyping of the ABCB1 c.3435 C\u2009>\u2009T polymorphism was \nperformed using Polymerase Chain Reaction-Restriction Fragment Length \nPolymorphism (PCR-RFLP) method, and CBZ plasma levels were measured to assess \nits effect on metabolism. Clinical data, including drug response, therapy type, \nand adverse drug reactions (ADRs), were collected and analyzed. For the \nstatistical analysis we used chi-squared tests and Exact Fisher's for \ncorrections. Our findings show no significant association between the ABCB1 \nc.3435C\u2009>\u2009T genotypes with carbamazepine resistance (p\u2009=\u20090,1) nor incidence of \nadverse reactions. This polymorphism also indicated no statistically significant \nlink with Carbamazepine plasma levels. The sample size in this study might be \nlimitation; therefore, expanded investigations on Algerian population are \nneeded. Although this study indicates no significant correlation of the ABCB1 \nc.3435C\u2009>\u2009T polymorphism with influencing CBZ Pharmacoresistance and therapeutic \noutcomes, larger-scale-studies are required to confirm these results and assess \ntheir reliability.\n\n\u00a9 2025.

Typically, epilepsy is treated with one \nof several available antiepileptic drugs and patients are able to experience \nfreedom from seizures with minimal side effects. However, there are some \npatients who do not respond to treatment and require the use of multiple drug \ncombinations or surgical intervention. Although there are few studies supporting \nits use, multi-drug regimens have been known to be helpful for patients, \nalthough clinicians should monitor patients for adverse side effects. Vagus \nnerve stimulation is the only US Food and Drug Administration-approved surgical \nneurostimulation therapy for epilepsy, and patients' conditions often progress \nfor many years before epilepsy surgery options are considered. Lastly, due to \nthe chronic nature of epilepsy, clinicians should be aware of the presence of \ncomorbid psychiatric conditions as well. This supplement is Part One in the \n\"Case in Point: Evidence-Based Insights for Epilepsy Management\" series. In this \nExpert Review Supplement, Andrew J.

This is the first comprehensive and systematic survey of epilepsy surgery \nlong-term outcome from our country.\nMETHODS: A descriptive cohort study was conducted between 1998 and 2008 for \ndrug-resistant epilepsy surgery with a minimum of 12 months follow-up (n=110). \nIn 84 cases (76.36%) resective surgery was performed, and outcome periodically \nassessed using the Engel score. Patients were stratified into groups: 12, 13-36, \n37-60 and over than 60 months of follow-up. Video-EEG with and without \nintracranial electrode implants, intraoperative electrocorticograms, Wada tests, \npathology reports, use of antiepileptic drugs (AEDs), and surgical complication \nrates were evaluated.\nRESULTS: Surgical techniques included: 69 lobectomies (62.7%), 15 lesionectomies \n(13.6%), 6 callosotomies (5.4%), 6 multiple subpial transection (5.4%), 11 vagus \nnerve stimulations (10%), 3 hemispherectomies (2.7%). Male: female ratio: \n1/1.44. Mean age at time of surgery: 26.2 years. Mean duration of epilepsy: 14 \nyears. Age at seizure onset: 11.5 years. Mean follow-up: 46 months. Pathology \nfindings: mesial temporal sclerosis 32 (35.1%); dual pathology 17 (18.7%); \ncortical dysplasia 15 (16.4%); non-specific inflammatory changes 11 (12.1%); \ntumors 7 (7.7%); other 6 (6.8%). Engel scores at 12 months follow-up: 72.6% (61) \nclass I, 16.6% (14) class II and 15.5% (13) class III-IV; 13-36 months after \nsurgery: 68.1% of cases were class I, 15.9% class II and 15.5% class III-IV. \nAfter 37-60 months, 74% class I, 14% class II, 14% class III-IV. Over 60 months \n(n=45) 78% class I, 13.5% class II and 8.1% class III-IV.\nCONCLUSION: Conducting a successful epilepsy surgery program in a developing \ncountry is challenging. These results should encourage specialists in these \ncountries.

Epilepsy is a chronic and disabling \nneurologic disorder, affecting approximately 1% of the population. Up to 30% of \npeople with epilepsy have seizures that are resistant to currently available \ndrugs. Felbamate is one of the second-generation antiepileptic drugs and we have \nassessed its effects as an add-on therapy to standard drugs in this review.\nOBJECTIVES: To evaluate the efficacy and tolerability of felbamate versus \nplacebo when used as an add-on treatment for people with refractory \npartial-onset epilepsy.\nSEARCH METHODS: For the latest update we searched the Cochrane Epilepsy \nSpecialized Register, CENTRAL, MEDLINE, ClinicalTrials.gov and the WHO \nInternational Clinical Trials Registry Platform, up to 20 October 2016. There \nwere no language and time restrictions. We reviewed the reference lists of \nretrieved studies to search for additional reports of relevant studies. We also \ncontacted the manufacturers of felbamate and experts in the field for \ninformation about any unpublished or ongoing studies.\nSELECTION CRITERIA: Randomised placebo-controlled add-on studies of people of \nany age with refractory partial-onset seizures. The studies could be \ndouble-blind, single-blind or unblinded and could be of parallel or cross-over \ndesign.\nDATA COLLECTION AND ANALYSIS: Two review authors independently selected studies \nfor inclusion and extracted information. We resolved disagreements by \ndiscussion. If disagreements persisted, the third review author arbitrated. We \nassessed the following outcomes: 50% or greater reduction in seizure frequency; \nabsolute or percentage reduction in seizure frequency; treatment withdrawal; \nadverse effects; quality of life.\nMAIN RESULTS: We included four randomised controlled trials with a total of 236 \nparticipants. Two trials were parallel design, the third had a two-period \ncross-over design, and the fourth had a three-period cross-over design. Two \nstudies were at an unclear risk of bias for random sequence generation and \nallocation concealment. These two studies did not include any description of \ntheir methods for outcome assessment and performance blinding (i.e. participants \nor doctors). Two studies were at high risk of bias for incomplete outcome data. \nDue to significant methodological heterogeneity, clinical heterogeneity and \ndifferences in outcome measures, it was not possible to perform a meta-analysis \nof the results. Only one study reported 50% or greater reduction in seizure \nfrequency. One study reported absolute and percentage reduction in seizure \nfrequency compared to placebo, P values were 0.046 and 0.018, respectively. One \nstudy reported percentage reduction in seizure frequency compared to placebo, \nbut there were no P values. Adverse effects rates were higher during the \nfelbamate period than the placebo period, particularly headache, nausea and \ndizziness.\nAUTHORS' CONCLUSIONS: In view of the methodological deficiencies, limited number \nof individual studies and differences in outcome measures, we have found no \nreliable evidence to support the use of felbamate as an add-on therapy in people \nwith refractory partial-onset epilepsy. A large-scale, randomised controlled \ntrial conducted over a longer period of time is required to inform clinical \npractice.\n\nDOI: 10.1002/14651858.CD008295.pub4\nPMCID: PMC6483495\nPMID: 28718506 [Indexed for MEDLINE]\n\nConflict of interest statement: Li Li Shi: no conflicts of interest JianCheng \nDong: no conflicts of interest HengJian Ni: no conflicts of interest JinSong \nGeng: no conflicts of interest Taixiang Wu: no conflicts of interest", "authors": "Shi LL, Dong J, Ni H et al.", "journal": "Cochrane Database Syst Rev", "year": "2017" }, "29067682": { "title": "Eslicarbazepine acetate add-on for drug-resistant partial epilepsy", "abstract": "3.

In this review, we summarized the current \nevidence regarding eslicarbazepine acetate (ESL) when used as an add-on \ntreatment for drug-resistant partial epilepsy.\nOBJECTIVES: To evaluate the efficacy and tolerability of ESL when used as an \nadd-on treatment for people with drug-resistant partial epilepsy.\nSEARCH METHODS: The searches for the original review were run in November 2011. \nSubsequently, we searched the Cochrane Epilepsy Group Specialized Register (6 \nDecember 2016), the Cochrane Central Register of Controlled Trials (CENTRAL \n2016, Issue 11) and MEDLINE (1946 to 6 December 2016). There were no language \nrestrictions. We reviewed the reference lists of retrieved studies to search for \nadditional reports of relevant studies. We also contacted the manufacturers of \nESL and experts in the field for information about any unpublished or ongoing \nstudies.\nSELECTION CRITERIA: Randomized placebo controlled double-blind add-on trials of \nESL in people with drug-resistant partial epilepsy.\nDATA COLLECTION AND ANALYSIS: Two review authors independently selected trials \nfor inclusion and extracted data. Outcomes investigated included 50% or greater \nreduction in seizure frequency, seizure freedom, treatment withdrawal, adverse \neffects, and drug interactions. Primary analyses were by intention to treat \n(ITT). The dose-response relationship was evaluated in regression models.\nMAIN RESULTS: We included five trials (1799 participants) rated at low risk of \nbias; all studies were funded by BIAL. The overall risk ratio (RR) with 95% \nconfidence interval (CI) for 50% or greater reduction in seizure frequency was \n1.71 (95% CI 1.42 to 2.05). Dose regression analysis showed evidence that ESL \nreduced seizure frequency with an increase in efficacy with increasing doses of \nESL. ESL was significantly associated with seizure freedom (RR 2.90, 95% CI 1.49 \nto 5.68). Participants were more likely to have ESL withdrawn for adverse \neffects (RR 2.66, 95% CI 1.42 to 4.96) but not for any reason (RR 1.19, 95% CI \n0.86 to 1.64). The following adverse effects were significantly associated with \nESL: dizziness (RR 2.81, 99% CI 1.86 to 4.27); nausea (RR 2.61, 99% CI 1.36 to \n5.01); diplopia (RR 4.14, 99% CI 1.74 to 9.84); somnolence (RR 1.71, 99% CI 1.11 \nto 2.63) and vomiting (RR 3.30, 99% CI 1.34 to 8.13). Overall the quality of the \nevidence was rated as moderate to high.\nAUTHORS' CONCLUSIONS: ESL reduces seizure frequency when used as an add-on \ntreatment for people with drug-resistant partial epilepsy. The trials included \nin this review were of short-term duration and focused on adults. One new trial \nhas been included in this update, but the conclusions are unchanged.\n\nDOI: 10.1002/14651858.CD008907.pub3\nPMCID: PMC6485774\nPMID: 29067682 [Indexed for MEDLINE]\n\nConflict of interest statement: None known.", "authors": "Chang XC, Yuan H, Wang Y et al.", "journal": "Cochrane Database Syst Rev", "year": "2017" }, "30143957": { "title": "Expected Budget Impact and Health Outcomes of Expanded Use of Vagus Nerve Stimulation Therapy for Drug-Resistant Epilepsy", "abstract": "4.

Costs included VNS device, placement, programming, and battery changes; \nadverse events associated with VNS (cough, voice alteration, device removal \nresulting from surgical site infection); AEDs; and seizure-related costs \naffected by seizure frequency, which affects resource utilization (i.e., \nhospitalizations, emergency department visits, neurologist visits). To estimate \nthe potential savings with VNS due to a reduction in seizure frequency, the \nbudget impact model uses the results of an underlying Markov model to estimate \nseizure-related costs by seizure frequency. Transitions occurred among four \nhealth states, defined by number of seizures per month (i.e., \nseizure-free,\u2009\u2264\u20091,\u2009>\u20091 to\u2009<\u200910,\u2009\u2265\u200910) on a 3-month cycle based on published \nclinical trials and registry data.\nRESULTS: VNS resulted in an estimated net cost savings, on average, over \n5\u00a0years, due to the expected reduction in seizure frequency. The initial cost of \nthe VNS device, placement, and programming was estimated to be offset 1.7\u00a0years \nafter VNS device placement. Reductions in hospitalizations were the main \ncontributor to the cost savings with VNS.\nCONCLUSIONS: VNS is a proven intervention that offers a long-term solution for \npatients with DRE by reducing seizure frequency, which leads to lower resource \nutilization and lower costs.\nFUNDING: LivaNova PLC.\n\nDOI: 10.1007/s12325-018-0775-0\nPMCID: PMC6182643\nPMID: 30143957 [Indexed for MEDLINE]\n\nConflict of interest statement: Alan Beckman is an employee of LivaNova PLC. \nFrancesca Barion is an employee of LivaNova PLC.

It has been reported to be effective for both \nfocal and generalized epilepsy; however, most of the relevant studies have \ninvolved children or young patients. Some patients develop intractable epilepsy \nafter stroke, despite taking antiepileptic drugs (AEDs). In this study, we \ninvestigated the efficacy of VNS for pharmacoresistant poststroke epilepsy \n(PPSE).\nMETHODS: We retrospectively studied 10 patients who underwent vagal nerve \nstimulator implantation for poststroke epilepsy after the seizures had proved \nrefractory to appropriate AEDs. The seizure outcome was evaluated using the \nMcHugh classification 2 years after the implantation.\nRESULTS: In total, 4 patients (40%) remained seizure-free throughout the 2-year \nduration. In addition, seizures were reduced by >50% after 2 years in 6 patients \n(60%). McHugh classification was class I for 5 patients and class II for 5 \npatients. Neither intraoperative complications nor postoperative adverse effects \nwere reported. The average intensity of VNS was 1.75 mA.\nCONCLUSIONS: In this small study, VNS proved to be a safe and effective therapy \nfor PPSE.

Epilepsy is a common neurological disorder, affecting 0.5% to \n1% of the population. For nearly 30% of these people, their epilepsy is \nresistant to currently available drugs. Pharmacological treatment remains the \nfirst choice to control epilepsy. Lamotrigine is one of the newer antiepileptic \ndrugs. Lamotrigine, in combination with other antiepileptic drugs (add-on), can \nreduce seizures, but with some adverse effects.\nOBJECTIVES: To determine the effects of lamotrigine on (1) seizures, (2) \nadverse-effect profile, and (3) cognition and quality of life, compared to \nplacebo, when used as an add-on treatment for people with drug-resistant focal \nepilepsy.\nSEARCH METHODS: For the latest update of the review, we searched the following \ndatabases on 9 March 2020: Cochrane Register of Studies (CRS Web), MEDLINE \n(Ovid, 1946 to March 06, 2020). CRS Web includes randomized or quasi-randomized, \ncontrolled trials from PubMed, EMBASE, ClinicalTrials.gov, the World Health \nOrganization International Clinical Trials Registry Platform (ICTRP), the \nCochrane Central Register of Controlled Trials (CENTRAL), and the Specialized \nRegisters of Cochrane Review Groups including Epilepsy. No language restrictions \nwere imposed.\nSELECTION CRITERIA: Randomised placebo-controlled trials of people with \ndrug-resistant focal epilepsy of any age, in which an adequate method of \nconcealment of randomisation was used. The studies were double-, single- or \nunblinded, placebo-controlled. For cross-over studies, the first treatment \nperiod was treated as a parallel trial. Eligible participants were adults or \nchildren with drug-resistant focal epilepsy.\nDATA COLLECTION AND ANALYSIS: For this update, two review authors independently \nassessed the trials for inclusion, and extracted data. Outcomes included 50% or \ngreater reduction in seizure frequency, treatment withdrawal (any reason), \nadverse effects, effects on cognition and quality of life. Primary analyses were \nby intention-to-treat. Sensitivity best- and worse-case analyses were undertaken \nto account for missing outcome data. Pooled risk ratios (RRs) with 95% \nconfidence intervals (95% Cls) were estimated for the primary outcomes of \nseizure frequency and treatment withdrawal. For adverse effects, we calculated \npooled RRs and 99% Cls.\nMAIN RESULTS: We did not identify any new studies for this update, therefore, \nthe results and conclusions are unchanged. In previous updates of this review, \nthe authors found five parallel add-on studies, eight cross-over studies in \nadults or children with drug-resistant focal epilepsy, and one parallel add-on \nstudy with a responder-enriched design in infants. In total, these 14 studies \nincluded 1806 eligible participants (38 infants, 199 children, 1569 adults). \nBaseline phases ranged from four to 12 weeks; treatment phases from eight to 36 \nweeks. Overall, 11 studies (1243 participants) were rated as having low risk of \nbias, and three (697 participants) had unclear risk of bias due to lack of \nreported information around study design. Effective blinding of studies was \nreported in four studies (563 participants). The overall risk ratio (RR) for 50% \nor greater reduction in seizure frequency was 1.80 (95% CI 1.45 to 2.23; 12 \ntrials, 1322 participants (adults and children); moderate-certainty evidence) \nindicating that lamotrigine was significantly more effective than placebo in \nreducing seizure frequency. The overall RR for treatment withdrawal (for any \nreason) was 1.11 (95% CI 0.91 to 1.37; 14 trials; 1806 participants; \nmoderate-certainty evidence). The adverse events significantly associated with \nlamotrigine were: ataxia, dizziness, diplopia (double vision), and nausea. The \nRR of these adverse effects were as follows: ataxia 3.34 (99% Cl 2.01 to 5.55; \n12 trials; 1525 participants; high-certainty evidence); dizziness 2.00 (99% Cl \n1.52 to 2.64;13 trials; 1768 participants; moderate-certainty evidence); \ndiplopia 3.79 (99% Cl 2.15 to 6.68; 3 trials, 944 participants; high-certainty \nevidence); nausea 1.81 (99% Cl 1.22 to 2.68; 12 studies,1486 participants; \nmoderate-certainty evidence). The limited data available precluded any \nconclusions about effects on cognition and quality of life. No important \nheterogeneity between studies was found for any of the outcomes. Overall, we \nassessed the evidence as high to moderate certainty, due to incomplete data for \nsome outcomes.\nAUTHORS' CONCLUSIONS: Lamotrigine as an add-on treatment for drug-resistant \nfocal seizures appears to be effective in reducing seizure frequency, and seems \nto be fairly well-tolerated. However, the trials were of relatively short \nduration and provided no evidence for the long term. Further trials are needed \nto assess the long-term effects of lamotrigine, and to compare lamotrigine with \nother add-on drugs.\n\nCopyright \u00a9 2020 The Cochrane Collaboration.

Despite the availability of over 20 antiseizure drugs (ASDs) for \nsymptomatic treatment of epileptic seizures, about one-third of patients with \nepilepsy have seizures refractory to pharmacotherapy. Patients with such \ndrug-resistant epilepsy (DRE) have increased risks of premature death, injuries, \npsychosocial dysfunction, and a reduced quality of life, so development of more \neffective therapies is an urgent clinical need. However, the various types of \nepilepsy and seizures and the complex temporal patterns of refractoriness \ncomplicate the issue. Furthermore, the underlying mechanisms of DRE are not \nfully understood, though recent work has begun to shape our understanding more \nclearly. Experimental models of DRE offer opportunities to discover, \ncharacterize, and challenge putative mechanisms of drug resistance. Furthermore, \nsuch preclinical models are important in developing therapies that may overcome \ndrug resistance. Here, we will review the current understanding of the \nmolecular, genetic, and structural mechanisms of ASD resistance and discuss how \nto overcome this problem. Encouragingly, better elucidation of the \npathophysiological mechanisms underpinning epilepsies and drug resistance by \nconcerted preclinical and clinical efforts have recently enabled a revised \napproach to the development of more promising therapies, including numerous \npotential etiology-specific drugs (\"precision medicine\") for severe pediatric \n(monogenetic) epilepsies and novel multitargeted ASDs for acquired partial \nepilepsies, suggesting that the long hoped-for breakthrough in therapy for \nas-yet ASD-resistant patients is a feasible goal. SIGNIFICANCE STATEMENT: Drug \nresistance provides a major challenge in epilepsy management. Here, we will \nreview the current understanding of the molecular, genetic, and structural \nmechanisms of drug resistance in epilepsy and discuss how the problem might be \novercome.\n\nCopyright \u00a9 2020 by The Author(s).\n\nDOI: 10.1124/pr.120.019539\nPMCID: PMC7300324\nPMID: 32540959 [Indexed for MEDLINE]", "authors": "L\u00f6scher W, Potschka H, Sisodiya SM et al.", "journal": "Pharmacol Rev", "year": "2020" }, "32847092": { "title": "Health Technology Assessment Report on Vagus Nerve Stimulation in Drug-Resistant Epilepsy", "abstract": "1.

Health \ntechnology assessment (HTA) represents a modern approach to the analysis of \ntechnologies used for healthcare. The purpose of this study is to assess the \nclinical, organizational, financial, and economic impact of VNS therapy in \ndrug-resistant epilepsies and to establish the congruity between costs incurred \nand health service reimbursement. Methods: The present study used an HTA \napproach. It is based on an extensive detailed bibliographic search on databases \n(Medline, Pubmed, Embase and Cochrane, sites of scientific societies and \ninstitutional sites). The HTA study includes the following issues: (a) social \nimpact and costs of the disease; (b) VNS eligibility and clinical results; (c) \nquality of life (QoL) after VNS therapy; (d) economic impact and productivity \nregained after VNS; and (e) costs of VNS. Results: Literature data indicate VNS \nas an effective treatment with a potential positive impact on social aspects and \non quality of life. The diagnosis-related group (DRG) financing, both on \nnational and regional levels, does not cover the cost of the medical device. \nThere was an evident insufficient coverage of the DRG compared to the full cost \nof implanting the device. Conclusions: VNS is a palliative treatment for \nreducing seizure frequency and intensity. Despite its economic cost, VNS should \nimprove patients' quality of life and reduce care needs.\n\nDOI: 10.3390/ijerph17176150\nPMCID: PMC7504285\nPMID: 32847092 [Indexed for MEDLINE]\n\nConflict of interest statement: The authors declare no conflict of interest.", "authors": "Marras CE, Colicchio G, De Palma L et al.", "journal": "Int J Environ Res Public Health", "year": "2020" }, "35883201": { "title": "Expedited epilepsy surgery prior to drug resistance in children: a frontier worth crossing?", "abstract": "5.

In this opinion piece, we outline the \nclinical and experimental evidence for selectively considering epilepsy surgery \nprior to drug resistance. Our rationale for expedited surgery is based on the \nobservations that (i) a high proportion of patients with lesional epilepsies \n(e.g. focal cortical dysplasia, epilepsy-associated tumours) will progress to \ndrug resistance; (ii) surgical treatment of these lesions, especially in \nnon-eloquent areas of brain, is safe; and (iii) earlier surgery may be \nassociated with better seizure outcomes. Potential benefits beyond seizure \nreduction or elimination include less exposure to antiseizure medications, which \nmay lead to improved developmental trajectories in children and optimize \nlong-term neurocognitive outcomes and quality of life. Further, there exists \nemerging experimental evidence that brain network dysfunction exists at the \nonset of epilepsy, where continuing dysfunctional activity could exacerbate \nnetwork perturbations. This in turn could lead to expanded seizure foci and \ncontribution to the comorbidities associated with epilepsy. Taken together, we \nrationalize that epilepsy surgery, in carefully selected cases, may be \nconsidered prior to drug resistance. Last, we outline the path forward, \nincluding the challenges associated with developing the evidence base and \nimplementing this paradigm into clinical care.\n\n\u00a9 The Author(s) 2022.

After \nexcluding treatable cases such as infectious or autoimmune encephalitis, our \nfocus shifted to a more challenging subgroup of 59 patients for in-depth genetic \nanalysis using exome sequencing (ES). The ES analysis identified 40 genetic \nabnormalities, significantly including de novo variants. Notably, we found \nstructural variation as duplications in regions 2q24.3, including SCN1A and \nSCN2A were observed in 7 cases. These genetic variants, impacting ion channels, \nglucose transport, transcription regulation, and kinases, play a crucial role in \ndetermining medication efficacy. More than one-third (34.2%) of patients with \nDEE had an unfavorable response to anti-seizure medications (ASMs) in the \nchronic phase. However, since the ketogenic supplementary diet showed a positive \neffect, more than three-quarters (80%) of these drug-resistant patients improved \nduring a 3-month follow-up. In contrast, the ME had a lower adverse reaction \nrate of 9.1% (2/22) to specialized medications, yet there were 5 fatalities and \n10 cases with unidentified genetic etiologies. This study suggests the potential \nof categorizing drug-resistant variants and that a ketogenic diet could be \nbeneficial in managing DEE and ME. It also opens new perspectives on the \nmechanisms of the ketogenic diet on the discovered genetic variants.\n\n\u00a9 2024.

Carbamazepine is frequently the \nfirst-line treatment, making early prediction of patient response essential for \npersonalized care. This approach helps reduce adverse effects and healthcare \ncosts, while enhancing patient outcomes. This study aims to explore the link \nbetween the ABCB1 c.3435C\u2009>\u2009T genetic variation and Carbamazepine resistance and \ntoxicity in Algerian patients with epilepsy, with a focus on the impact of \ngenetic variations on Carbamazepine plasma concentrations and treatment \noutcomes. Ninety-eight Algerian patients with epilepsy were recruited and \ncategorized as either drug-responsive or drug-resistant based on their clinical \nresponse to CBZ treatment. Genotyping of the ABCB1 c.3435 C\u2009>\u2009T polymorphism was \nperformed using Polymerase Chain Reaction-Restriction Fragment Length \nPolymorphism (PCR-RFLP) method, and CBZ plasma levels were measured to assess \nits effect on metabolism. Clinical data, including drug response, therapy type, \nand adverse drug reactions (ADRs), were collected and analyzed. For the \nstatistical analysis we used chi-squared tests and Exact Fisher's for \ncorrections. Our findings show no significant association between the ABCB1 \nc.3435C\u2009>\u2009T genotypes with carbamazepine resistance (p\u2009=\u20090,1) nor incidence of \nadverse reactions. This polymorphism also indicated no statistically significant \nlink with Carbamazepine plasma levels. The sample size in this study might be \nlimitation; therefore, expanded investigations on Algerian population are \nneeded. Although this study indicates no significant correlation of the ABCB1 \nc.3435C\u2009>\u2009T polymorphism with influencing CBZ Pharmacoresistance and therapeutic \noutcomes, larger-scale-studies are required to confirm these results and assess \ntheir reliability.\n\n\u00a9 2025.

Typically, epilepsy is treated with one \nof several available antiepileptic drugs and patients are able to experience \nfreedom from seizures with minimal side effects. However, there are some \npatients who do not respond to treatment and require the use of multiple drug \ncombinations or surgical intervention. Although there are few studies supporting \nits use, multi-drug regimens have been known to be helpful for patients, \nalthough clinicians should monitor patients for adverse side effects. Vagus \nnerve stimulation is the only US Food and Drug Administration-approved surgical \nneurostimulation therapy for epilepsy, and patients' conditions often progress \nfor many years before epilepsy surgery options are considered. Lastly, due to \nthe chronic nature of epilepsy, clinicians should be aware of the presence of \ncomorbid psychiatric conditions as well.

This is the first comprehensive and systematic survey of epilepsy surgery \nlong-term outcome from our country.\nMETHODS: A descriptive cohort study was conducted between 1998 and 2008 for \ndrug-resistant epilepsy surgery with a minimum of 12 months follow-up (n=110). \nIn 84 cases (76.36%) resective surgery was performed, and outcome periodically \nassessed using the Engel score. Patients were stratified into groups: 12, 13-36, \n37-60 and over than 60 months of follow-up. Video-EEG with and without \nintracranial electrode implants, intraoperative electrocorticograms, Wada tests, \npathology reports, use of antiepileptic drugs (AEDs), and surgical complication \nrates were evaluated.\nRESULTS: Surgical techniques included: 69 lobectomies (62.7%), 15 lesionectomies \n(13.6%), 6 callosotomies (5.4%), 6 multiple subpial transection (5.4%), 11 vagus \nnerve stimulations (10%), 3 hemispherectomies (2.7%). Male: female ratio: \n1/1.44. Mean age at time of surgery: 26.2 years. Mean duration of epilepsy: 14 \nyears. Age at seizure onset: 11.5 years. Mean follow-up: 46 months. Pathology \nfindings: mesial temporal sclerosis 32 (35.1%); dual pathology 17 (18.7%); \ncortical dysplasia 15 (16.4%); non-specific inflammatory changes 11 (12.1%); \ntumors 7 (7.7%); other 6 (6.8%). Engel scores at 12 months follow-up: 72.6% (61) \nclass I, 16.6% (14) class II and 15.5% (13) class III-IV; 13-36 months after \nsurgery: 68.1% of cases were class I, 15.9% class II and 15.5% class III-IV. \nAfter 37-60 months, 74% class I, 14% class II, 14% class III-IV. Over 60 months \n(n=45) 78% class I, 13.5% class II and 8.1% class III-IV.\nCONCLUSION: Conducting a successful epilepsy surgery program in a developing \ncountry is challenging. These results should encourage specialists in these \ncountries.

Epilepsy is a chronic and disabling \nneurologic disorder, affecting approximately 1% of the population. Up to 30% of \npeople with epilepsy have seizures that are resistant to currently available \ndrugs. Felbamate is one of the second-generation antiepileptic drugs and we have \nassessed its effects as an add-on therapy to standard drugs in this review.\nOBJECTIVES: To evaluate the efficacy and tolerability of felbamate versus \nplacebo when used as an add-on treatment for people with refractory \npartial-onset epilepsy.\nSEARCH METHODS: For the latest update we searched the Cochrane Epilepsy \nSpecialized Register, CENTRAL, MEDLINE, ClinicalTrials.gov and the WHO \nInternational Clinical Trials Registry Platform, up to 20 October 2016. There \nwere no language and time restrictions. We reviewed the reference lists of \nretrieved studies to search for additional reports of relevant studies. We also \ncontacted the manufacturers of felbamate and experts in the field for \ninformation about any unpublished or ongoing studies.\nSELECTION CRITERIA: Randomised placebo-controlled add-on studies of people of \nany age with refractory partial-onset seizures. The studies could be \ndouble-blind, single-blind or unblinded and could be of parallel or cross-over \ndesign.\nDATA COLLECTION AND ANALYSIS: Two review authors independently selected studies \nfor inclusion and extracted information. We resolved disagreements by \ndiscussion. If disagreements persisted, the third review author arbitrated. We \nassessed the following outcomes: 50% or greater reduction in seizure frequency; \nabsolute or percentage reduction in seizure frequency; treatment withdrawal; \nadverse effects; quality of life.\nMAIN RESULTS: We included four randomised controlled trials with a total of 236 \nparticipants. Two trials were parallel design, the third had a two-period \ncross-over design, and the fourth had a three-period cross-over design. Two \nstudies were at an unclear risk of bias for random sequence generation and \nallocation concealment. These two studies did not include any description of \ntheir methods for outcome assessment and performance blinding (i.e. participants \nor doctors). Two studies were at high risk of bias for incomplete outcome data. \nDue to significant methodological heterogeneity, clinical heterogeneity and \ndifferences in outcome measures, it was not possible to perform a meta-analysis \nof the results. Only one study reported 50% or greater reduction in seizure \nfrequency. One study reported absolute and percentage reduction in seizure \nfrequency compared to placebo, P values were 0.046 and 0.018, respectively. One \nstudy reported percentage reduction in seizure frequency compared to placebo, \nbut there were no P values. Adverse effects rates were higher during the \nfelbamate period than the placebo period, particularly headache, nausea and \ndizziness.\nAUTHORS' CONCLUSIONS: In view of the methodological deficiencies, limited number \nof individual studies and differences in outcome measures, we have found no \nreliable evidence to support the use of felbamate as an add-on therapy in people \nwith refractory partial-onset epilepsy. A large-scale, randomised controlled \ntrial conducted over a longer period of time is required to inform clinical \npractice.\n\nDOI: 10.1002/14651858.CD008295.pub4\nPMCID: PMC6483495\nPMID: 28718506 [Indexed for MEDLINE]\n\nConflict of interest statement: Li Li Shi: no conflicts of interest JianCheng \nDong: no conflicts of interest HengJian Ni: no conflicts of interest JinSong \nGeng: no conflicts of interest Taixiang Wu: no conflicts of interest", "authors": "Shi LL, Dong J, Ni H et al.", "journal": "Cochrane Database Syst Rev", "year": "2017" }, "29067682": { "title": "Eslicarbazepine acetate add-on for drug-resistant partial epilepsy", "abstract": "3.

In this review, we summarized the current \nevidence regarding eslicarbazepine acetate (ESL) when used as an add-on \ntreatment for drug-resistant partial epilepsy.\nOBJECTIVES: To evaluate the efficacy and tolerability of ESL when used as an \nadd-on treatment for people with drug-resistant partial epilepsy.\nSEARCH METHODS: The searches for the original review were run in November 2011. \nSubsequently, we searched the Cochrane Epilepsy Group Specialized Register (6 \nDecember 2016), the Cochrane Central Register of Controlled Trials (CENTRAL \n2016, Issue 11) and MEDLINE (1946 to 6 December 2016). There were no language \nrestrictions. We reviewed the reference lists of retrieved studies to search for \nadditional reports of relevant studies. We also contacted the manufacturers of \nESL and experts in the field for information about any unpublished or ongoing \nstudies.\nSELECTION CRITERIA: Randomized placebo controlled double-blind add-on trials of \nESL in people with drug-resistant partial epilepsy.\nDATA COLLECTION AND ANALYSIS: Two review authors independently selected trials \nfor inclusion and extracted data. Outcomes investigated included 50% or greater \nreduction in seizure frequency, seizure freedom, treatment withdrawal, adverse \neffects, and drug interactions. Primary analyses were by intention to treat \n(ITT). The dose-response relationship was evaluated in regression models.\nMAIN RESULTS: We included five trials (1799 participants) rated at low risk of \nbias; all studies were funded by BIAL. The overall risk ratio (RR) with 95% \nconfidence interval (CI) for 50% or greater reduction in seizure frequency was \n1.71 (95% CI 1.42 to 2.05). Dose regression analysis showed evidence that ESL \nreduced seizure frequency with an increase in efficacy with increasing doses of \nESL. ESL was significantly associated with seizure freedom (RR 2.90, 95% CI 1.49 \nto 5.68). Participants were more likely to have ESL withdrawn for adverse \neffects (RR 2.66, 95% CI 1.42 to 4.96) but not for any reason (RR 1.19, 95% CI \n0.86 to 1.64). The following adverse effects were significantly associated with \nESL: dizziness (RR 2.81, 99% CI 1.86 to 4.27); nausea (RR 2.61, 99% CI 1.36 to \n5.01); diplopia (RR 4.14, 99% CI 1.74 to 9.84); somnolence (RR 1.71, 99% CI 1.11 \nto 2.63) and vomiting (RR 3.30, 99% CI 1.34 to 8.13). Overall the quality of the \nevidence was rated as moderate to high.\nAUTHORS' CONCLUSIONS: ESL reduces seizure frequency when used as an add-on \ntreatment for people with drug-resistant partial epilepsy. The trials included \nin this review were of short-term duration and focused on adults. One new trial \nhas been included in this update, but the conclusions are unchanged.\n\nDOI: 10.1002/14651858.CD008907.pub3\nPMCID: PMC6485774\nPMID: 29067682 [Indexed for MEDLINE]\n\nConflict of interest statement: None known.", "authors": "Chang XC, Yuan H, Wang Y et al.", "journal": "Cochrane Database Syst Rev", "year": "2017" }, "30143957": { "title": "Expected Budget Impact and Health Outcomes of Expanded Use of Vagus Nerve Stimulation Therapy for Drug-Resistant Epilepsy", "abstract": "4.

Costs included VNS device, placement, programming, and battery changes; \nadverse events associated with VNS (cough, voice alteration, device removal \nresulting from surgical site infection); AEDs; and seizure-related costs \naffected by seizure frequency, which affects resource utilization (i.e., \nhospitalizations, emergency department visits, neurologist visits). To estimate \nthe potential savings with VNS due to a reduction in seizure frequency, the \nbudget impact model uses the results of an underlying Markov model to estimate \nseizure-related costs by seizure frequency. Transitions occurred among four \nhealth states, defined by number of seizures per month (i.e., \nseizure-free,\u2009\u2264\u20091,\u2009>\u20091 to\u2009<\u200910,\u2009\u2265\u200910) on a 3-month cycle based on published \nclinical trials and registry data.\nRESULTS: VNS resulted in an estimated net cost savings, on average, over \n5\u00a0years, due to the expected reduction in seizure frequency. The initial cost of \nthe VNS device, placement, and programming was estimated to be offset 1.7\u00a0years \nafter VNS device placement. Reductions in hospitalizations were the main \ncontributor to the cost savings with VNS.\nCONCLUSIONS: VNS is a proven intervention that offers a long-term solution for \npatients with DRE by reducing seizure frequency, which leads to lower resource \nutilization and lower costs.\nFUNDING: LivaNova PLC.\n\nDOI: 10.1007/s12325-018-0775-0\nPMCID: PMC6182643\nPMID: 30143957 [Indexed for MEDLINE]\n\nConflict of interest statement: Alan Beckman is an employee of LivaNova PLC. \nFrancesca Barion is an employee of LivaNova PLC.

It has been reported to be effective for both \nfocal and generalized epilepsy; however, most of the relevant studies have \ninvolved children or young patients. Some patients develop intractable epilepsy \nafter stroke, despite taking antiepileptic drugs (AEDs). In this study, we \ninvestigated the efficacy of VNS for pharmacoresistant poststroke epilepsy \n(PPSE).\nMETHODS: We retrospectively studied 10 patients who underwent vagal nerve \nstimulator implantation for poststroke epilepsy after the seizures had proved \nrefractory to appropriate AEDs. The seizure outcome was evaluated using the \nMcHugh classification 2 years after the implantation.\nRESULTS: In total, 4 patients (40%) remained seizure-free throughout the 2-year \nduration. In addition, seizures were reduced by >50% after 2 years in 6 patients \n(60%). McHugh classification was class I for 5 patients and class II for 5 \npatients. Neither intraoperative complications nor postoperative adverse effects \nwere reported. The average intensity of VNS was 1.75 mA.\nCONCLUSIONS: In this small study, VNS proved to be a safe and effective therapy \nfor PPSE. Patients with poststroke epilepsy experience physical or mental \ndecline; therefore, it is important to control seizures in them to avoid \ndeterioration in their quality of daily life.\n\nCopyright \u00a9 2019 Elsevier Inc.

Epilepsy is a common neurological disorder, affecting 0.5% to \n1% of the population. For nearly 30% of these people, their epilepsy is \nresistant to currently available drugs. Pharmacological treatment remains the \nfirst choice to control epilepsy. Lamotrigine is one of the newer antiepileptic \ndrugs. Lamotrigine, in combination with other antiepileptic drugs (add-on), can \nreduce seizures, but with some adverse effects.\nOBJECTIVES: To determine the effects of lamotrigine on (1) seizures, (2) \nadverse-effect profile, and (3) cognition and quality of life, compared to \nplacebo, when used as an add-on treatment for people with drug-resistant focal \nepilepsy.\nSEARCH METHODS: For the latest update of the review, we searched the following \ndatabases on 9 March 2020: Cochrane Register of Studies (CRS Web), MEDLINE \n(Ovid, 1946 to March 06, 2020). CRS Web includes randomized or quasi-randomized, \ncontrolled trials from PubMed, EMBASE, ClinicalTrials.gov, the World Health \nOrganization International Clinical Trials Registry Platform (ICTRP), the \nCochrane Central Register of Controlled Trials (CENTRAL), and the Specialized \nRegisters of Cochrane Review Groups including Epilepsy. No language restrictions \nwere imposed.\nSELECTION CRITERIA: Randomised placebo-controlled trials of people with \ndrug-resistant focal epilepsy of any age, in which an adequate method of \nconcealment of randomisation was used. The studies were double-, single- or \nunblinded, placebo-controlled. For cross-over studies, the first treatment \nperiod was treated as a parallel trial. Eligible participants were adults or \nchildren with drug-resistant focal epilepsy.\nDATA COLLECTION AND ANALYSIS: For this update, two review authors independently \nassessed the trials for inclusion, and extracted data. Outcomes included 50% or \ngreater reduction in seizure frequency, treatment withdrawal (any reason), \nadverse effects, effects on cognition and quality of life. Primary analyses were \nby intention-to-treat. Sensitivity best- and worse-case analyses were undertaken \nto account for missing outcome data. Pooled risk ratios (RRs) with 95% \nconfidence intervals (95% Cls) were estimated for the primary outcomes of \nseizure frequency and treatment withdrawal. For adverse effects, we calculated \npooled RRs and 99% Cls.\nMAIN RESULTS: We did not identify any new studies for this update, therefore, \nthe results and conclusions are unchanged. In previous updates of this review, \nthe authors found five parallel add-on studies, eight cross-over studies in \nadults or children with drug-resistant focal epilepsy, and one parallel add-on \nstudy with a responder-enriched design in infants. In total, these 14 studies \nincluded 1806 eligible participants (38 infants, 199 children, 1569 adults). \nBaseline phases ranged from four to 12 weeks; treatment phases from eight to 36 \nweeks. Overall, 11 studies (1243 participants) were rated as having low risk of \nbias, and three (697 participants) had unclear risk of bias due to lack of \nreported information around study design. Effective blinding of studies was \nreported in four studies (563 participants). The overall risk ratio (RR) for 50% \nor greater reduction in seizure frequency was 1.80 (95% CI 1.45 to 2.23; 12 \ntrials, 1322 participants (adults and children); moderate-certainty evidence) \nindicating that lamotrigine was significantly more effective than placebo in \nreducing seizure frequency. The overall RR for treatment withdrawal (for any \nreason) was 1.11 (95% CI 0.91 to 1.37; 14 trials; 1806 participants; \nmoderate-certainty evidence). The adverse events significantly associated with \nlamotrigine were: ataxia, dizziness, diplopia (double vision), and nausea. The \nRR of these adverse effects were as follows: ataxia 3.34 (99% Cl 2.01 to 5.55; \n12 trials; 1525 participants; high-certainty evidence); dizziness 2.00 (99% Cl \n1.52 to 2.64;13 trials; 1768 participants; moderate-certainty evidence); \ndiplopia 3.79 (99% Cl 2.15 to 6.68; 3 trials, 944 participants; high-certainty \nevidence); nausea 1.81 (99% Cl 1.22 to 2.68; 12 studies,1486 participants; \nmoderate-certainty evidence). The limited data available precluded any \nconclusions about effects on cognition and quality of life. No important \nheterogeneity between studies was found for any of the outcomes. Overall, we \nassessed the evidence as high to moderate certainty, due to incomplete data for \nsome outcomes.\nAUTHORS' CONCLUSIONS: Lamotrigine as an add-on treatment for drug-resistant \nfocal seizures appears to be effective in reducing seizure frequency, and seems \nto be fairly well-tolerated. However, the trials were of relatively short \nduration and provided no evidence for the long term. Further trials are needed \nto assess the long-term effects of lamotrigine, and to compare lamotrigine with \nother add-on drugs.\n\nCopyright \u00a9 2020 The Cochrane Collaboration.

Despite the availability of over 20 antiseizure drugs (ASDs) for \nsymptomatic treatment of epileptic seizures, about one-third of patients with \nepilepsy have seizures refractory to pharmacotherapy. Patients with such \ndrug-resistant epilepsy (DRE) have increased risks of premature death, injuries, \npsychosocial dysfunction, and a reduced quality of life, so development of more \neffective therapies is an urgent clinical need. However, the various types of \nepilepsy and seizures and the complex temporal patterns of refractoriness \ncomplicate the issue. Furthermore, the underlying mechanisms of DRE are not \nfully understood, though recent work has begun to shape our understanding more \nclearly. Experimental models of DRE offer opportunities to discover, \ncharacterize, and challenge putative mechanisms of drug resistance. Furthermore, \nsuch preclinical models are important in developing therapies that may overcome \ndrug resistance. Here, we will review the current understanding of the \nmolecular, genetic, and structural mechanisms of ASD resistance and discuss how \nto overcome this problem. Encouragingly, better elucidation of the \npathophysiological mechanisms underpinning epilepsies and drug resistance by \nconcerted preclinical and clinical efforts have recently enabled a revised \napproach to the development of more promising therapies, including numerous \npotential etiology-specific drugs (\"precision medicine\") for severe pediatric \n(monogenetic) epilepsies and novel multitargeted ASDs for acquired partial \nepilepsies, suggesting that the long hoped-for breakthrough in therapy for \nas-yet ASD-resistant patients is a feasible goal. SIGNIFICANCE STATEMENT: Drug \nresistance provides a major challenge in epilepsy management. Here, we will \nreview the current understanding of the molecular, genetic, and structural \nmechanisms of drug resistance in epilepsy and discuss how the problem might be \novercome.\n\nCopyright \u00a9 2020 by The Author(s).\n\nDOI: 10.1124/pr.120.019539\nPMCID: PMC7300324\nPMID: 32540959 [Indexed for MEDLINE]", "authors": "L\u00f6scher W, Potschka H, Sisodiya SM et al.", "journal": "Pharmacol Rev", "year": "2020" }, "32847092": { "title": "Health Technology Assessment Report on Vagus Nerve Stimulation in Drug-Resistant Epilepsy", "abstract": "1.

Health \ntechnology assessment (HTA) represents a modern approach to the analysis of \ntechnologies used for healthcare. The purpose of this study is to assess the \nclinical, organizational, financial, and economic impact of VNS therapy in \ndrug-resistant epilepsies and to establish the congruity between costs incurred \nand health service reimbursement. Methods: The present study used an HTA \napproach. It is based on an extensive detailed bibliographic search on databases \n(Medline, Pubmed, Embase and Cochrane, sites of scientific societies and \ninstitutional sites). The HTA study includes the following issues: (a) social \nimpact and costs of the disease; (b) VNS eligibility and clinical results; (c) \nquality of life (QoL) after VNS therapy; (d) economic impact and productivity \nregained after VNS; and (e) costs of VNS. Results: Literature data indicate VNS \nas an effective treatment with a potential positive impact on social aspects and \non quality of life. The diagnosis-related group (DRG) financing, both on \nnational and regional levels, does not cover the cost of the medical device. \nThere was an evident insufficient coverage of the DRG compared to the full cost \nof implanting the device. Conclusions: VNS is a palliative treatment for \nreducing seizure frequency and intensity. Despite its economic cost, VNS should \nimprove patients' quality of life and reduce care needs.\n\nDOI: 10.3390/ijerph17176150\nPMCID: PMC7504285\nPMID: 32847092 [Indexed for MEDLINE]\n\nConflict of interest statement: The authors declare no conflict of interest.", "authors": "Marras CE, Colicchio G, De Palma L et al.", "journal": "Int J Environ Res Public Health", "year": "2020" }, "35883201": { "title": "Expedited epilepsy surgery prior to drug resistance in children: a frontier worth crossing?", "abstract": "5.

In this opinion piece, we outline the \nclinical and experimental evidence for selectively considering epilepsy surgery \nprior to drug resistance. Our rationale for expedited surgery is based on the \nobservations that (i) a high proportion of patients with lesional epilepsies \n(e.g. focal cortical dysplasia, epilepsy-associated tumours) will progress to \ndrug resistance; (ii) surgical treatment of these lesions, especially in \nnon-eloquent areas of brain, is safe; and (iii) earlier surgery may be \nassociated with better seizure outcomes. Potential benefits beyond seizure \nreduction or elimination include less exposure to antiseizure medications, which \nmay lead to improved developmental trajectories in children and optimize \nlong-term neurocognitive outcomes and quality of life. Further, there exists \nemerging experimental evidence that brain network dysfunction exists at the \nonset of epilepsy, where continuing dysfunctional activity could exacerbate \nnetwork perturbations. This in turn could lead to expanded seizure foci and \ncontribution to the comorbidities associated with epilepsy. Taken together, we \nrationalize that epilepsy surgery, in carefully selected cases, may be \nconsidered prior to drug resistance. Last, we outline the path forward, \nincluding the challenges associated with developing the evidence base and \nimplementing this paradigm into clinical care.\n\n\u00a9 The Author(s) 2022.

After \nexcluding treatable cases such as infectious or autoimmune encephalitis, our \nfocus shifted to a more challenging subgroup of 59 patients for in-depth genetic \nanalysis using exome sequencing (ES). The ES analysis identified 40 genetic \nabnormalities, significantly including de novo variants. Notably, we found \nstructural variation as duplications in regions 2q24.3, including SCN1A and \nSCN2A were observed in 7 cases. These genetic variants, impacting ion channels, \nglucose transport, transcription regulation, and kinases, play a crucial role in \ndetermining medication efficacy. More than one-third (34.2%) of patients with \nDEE had an unfavorable response to anti-seizure medications (ASMs) in the \nchronic phase. However, since the ketogenic supplementary diet showed a positive \neffect, more than three-quarters (80%) of these drug-resistant patients improved \nduring a 3-month follow-up. In contrast, the ME had a lower adverse reaction \nrate of 9.1% (2/22) to specialized medications, yet there were 5 fatalities and \n10 cases with unidentified genetic etiologies. This study suggests the potential \nof categorizing drug-resistant variants and that a ketogenic diet could be \nbeneficial in managing DEE and ME. It also opens new perspectives on the \nmechanisms of the ketogenic diet on the discovered genetic variants.\n\n\u00a9 2024.

Carbamazepine is frequently the \nfirst-line treatment, making early prediction of patient response essential for \npersonalized care. This approach helps reduce adverse effects and healthcare \ncosts, while enhancing patient outcomes. This study aims to explore the link \nbetween the ABCB1 c.3435C\u2009>\u2009T genetic variation and Carbamazepine resistance and \ntoxicity in Algerian patients with epilepsy, with a focus on the impact of \ngenetic variations on Carbamazepine plasma concentrations and treatment \noutcomes. Ninety-eight Algerian patients with epilepsy were recruited and \ncategorized as either drug-responsive or drug-resistant based on their clinical \nresponse to CBZ treatment. Genotyping of the ABCB1 c.3435 C\u2009>\u2009T polymorphism was \nperformed using Polymerase Chain Reaction-Restriction Fragment Length \nPolymorphism (PCR-RFLP) method, and CBZ plasma levels were measured to assess \nits effect on metabolism. Clinical data, including drug response, therapy type, \nand adverse drug reactions (ADRs), were collected and analyzed. For the \nstatistical analysis we used chi-squared tests and Exact Fisher's for \ncorrections. Our findings show no significant association between the ABCB1 \nc.3435C\u2009>\u2009T genotypes with carbamazepine resistance (p\u2009=\u20090,1) nor incidence of \nadverse reactions. This polymorphism also indicated no statistically significant \nlink with Carbamazepine plasma levels. The sample size in this study might be \nlimitation; therefore, expanded investigations on Algerian population are \nneeded. Although this study indicates no significant correlation of the ABCB1 \nc.3435C\u2009>\u2009T polymorphism with influencing CBZ Pharmacoresistance and therapeutic \noutcomes, larger-scale-studies are required to confirm these results and assess \ntheir reliability.\n\n\u00a9 2025.
