Purpose: Acute-on-chronic subdural hematoma (acSDH) describes acute bleeding into a chronic subdural hematoma (SDH), after surgery or second trauma. Because seizures are a well-known complication of SDH, associated with substantial morbidity and mortality, we aimed to analyze the incidence of acute symptomatic seizures (ASz), including status epilepticus, and determine the functional outcomes in this specific cohort of patients.
Methods: A retrospective analysis was performed, including patients with acSDH who were admitted to our department between 2010 and 2019. The incidence and timely onset of ASz and status epilepticus were evaluated. Functional outcomes at discharge and at 3–6 month follow-up were analyzed based on the modified Rankin scale.
Results: Of 506 patients with chronic SDH, 29 patients (5.7%) were diagnosed with acSDH. The overall incidence of ASz and status epilepticus were 72.4% and 10.3%, respectively. Favorable outcomes were identified in 11 patients (52.4%) in the ASz group compared with 6 patients (75%) in the non-ASz group. The mortality rate was higher in the ASz group compared with that in the control group (29% vs 0%). At follow-up, favorable outcomes were similar to those observed at discharge (52.4% in the ASz group and 71.4% in the control group). The mortality rate was still higher in the ASz group, at 32% compared with 14% for the control group.
Conclusion: AcSDH has a high risk for ASz, including status epilepticus, and is associated with unfavorable outcomes and high mortality. Thus, prophylactic treatment with antiepileptic drugs should be considered among this specific cohort of patients.
Der Status epilepticus (SE) stellt eine schwerwiegende akute Erkrankung dar, die eine frühzeitige und gezielte Therapie erfordert. Insbesondere der refraktäre SE (RSE) sowie der superrefraktäre SE (SRSE) sind bereits bei jungen Menschen eine interdisziplinäre therapeutische Herausforderung. Bei Patienten in höherem Lebensalter sind hierbei weitere relevante Aspekte zu beachten, die sich einerseits aufgrund einer abweichenden Pharmakokinetik und -dynamik ergeben, andererseits aber auch aus Komorbiditäten, Polypharmazie und möglichen medizinischen Therapielimitationen bzw. Patientenpräferenzen resultieren. Ziel dieses Artikels ist es, diese besonderen Aspekte im Rahmen der SE-Versorgung älterer Menschen aufzuarbeiten und potenzielle Therapiestrategien jenseits der Leitlinie aufzuzeigen. Insbesondere wird hierbei auf alternative Applikationswege und mögliche konservative Eskalationsformen der Therapie eingegangen, die v. a. bei relevant vorerkrankten Patienten von Bedeutung sind, bei denen eine intensivmedizinische Behandlung die ohnehin schon hohe Mortalität des SE im gehobenen Alter weiter erhöhen würde. Mit unterschiedlichen parenteralen Applikationsformen von Benzodiazepinen im SE sowie dem mittlerweile gut beschriebenen Einsatz weiterer Antikonvulsiva wie Brivaracetam, Perampanel, Stiripentol, Topiramat und Zonisamid in RSE und SRSE stehen auch für diese vulnerable Patientengruppe adäquate Therapieoptionen zur Verfügung. Nichtsdestotrotz sollte in der Therapie des SE im gehobenen Alter insbesondere in Anbetracht der per se hohen Mortalität verstärkt auf Patientenpräferenzen und medizinethische Aspekte geachtet werden.

Background: Novel treatments are needed to control refractory status epilepticus (SE). This study aimed to assess the potential effectiveness of fenfluramine (FFA) as an acute treatment option for SE. We present a summary of clinical cases where oral FFA was used in SE.
Methods: A case of an adult patient with Lennox–Gastaut syndrome (LGS) who was treated with FFA due to refractory SE is presented in detail. To identify studies that evaluated the use of FFA in SE, we performed a systematic literature search.
Results: Four case reports on the acute treatment with FFA of SE in children and adults with Dravet syndrome (DS) and LGS were available. We report in detail a 30-year-old woman with LGS of structural etiology, who presented with generalized tonic and dialeptic seizures manifesting at high frequencies without a return to clinical baseline constituting the diagnosis of SE. Treatment with anti-seizure medications up to lacosamide 600 mg/d, brivaracetam 300 mg/d, valproate 1,600 mg/d, and various benzodiazepines did not resolve the SE. Due to ongoing refractory SE and following an unremarkable echocardiography, treatment was initiated with FFA, with an initial dose of 10 mg/d (0.22 mg/kg body weight [bw]) and fast up-titration to 26 mg/d (0.58 mg/kg bw) within 10 days. Subsequently, the patient experienced a resolution of SE within 4 days, accompanied by a notable improvement in clinical presentation and regaining her mobility, walking with the assistance of physiotherapists. In the three cases reported in the literature, DS patients with SE were treated with FFA, and a cessation of SE was observed within a few days. No treatment-emergent adverse events were observed during FFA treatment in any of the four cases.
Conclusions: Based on the reported cases, FFA might be a promising option for the acute treatment of SE in patients with DS and LGS. Observational data show a decreased SE frequency while on FFA, suggesting a potentially preventive role of FFA in these populations.
Key points
* We summarize four cases of refractory status epilepticus (SE) successfully treated with fenfluramine.
* Refractory SE resolved after 4–7 days on fenfluramine.
* Swift fenfluramine up-titration was well-tolerated during SE treatment.
* Treatment-emergent adverse events on fenfluramine were not observed.
* Fenfluramine might be a valuable acute treatment option for SE in Dravet and Lennox–Gastaut syndromes.
Der Vorstand der Deutschen Gesellschaft für Epileptologie und die Kommission „Epilepsie und Synkopen“ der Deutschen Gesellschaft für Neurologie haben die aktuelle Datenlage zur Impfung zur Vorbeugung der Corona-Virus-Krankheit 2019 (COVID-19) sowie zur Impfpriorisierung bei Menschen mit Epilepsie gesichtet, diese zusammengefasst und geben die unten genannten Empfehlungen ab.
Hintergrund: Das Dravet-Syndrom (DS) ist ein seltenes, in der frühen Kindheit beginnendes, therapierefraktäres Epilepsiesyndrom, das mit einer hohen Morbidität und Mortalität verbunden ist.
Fragestellung: Ziele der Querschnittsstudie „Dravet syndrome caregiver survey“ (DISCUSS) sind die Identifizierung und Beschreibung der Faktoren, die einen Einfluss auf die Krankheitslast von Patienten mit DS und ihre Betreuer haben können. Die Ergebnisse der deutschen Kohorte werden vorgestellt.
Material und Methoden: Die Datenerhebung erfolgte durch eine anonyme Befragung von Eltern. Die Ergebnisse wurden für die verschiedenen Altersgruppen statistisch ausgewertet.
Ergebnisse: Der Fragebogen wurde von 68 Eltern der DS-Patienten mit einem durchschnittlichen Alter von 10 Jahren (Median: 9, Spanne: 1–26) ausgefüllt. Nur 3 Patienten (4,4 %) waren in den letzten 3 Monaten anfallsfrei. Insgesamt hatten 97 % der Patienten, die älter als 5 Jahre waren (n = 45), mindestens eine Komorbidität. Die zum Befragungszeitpunkt am häufigsten eingenommenen Antiepileptika waren Valproat, Kaliumbromid, Stiripentol, Clobazam und Topiramat. In der Vergangenheit wurden Natriumkanalblocker, Phenobarbital und Levetiracetam eingesetzt, aktuell fanden diese Antiepileptika nur selten Verwendung. Die Lebensqualität der Patienten war niedriger als die der Allgemeinbevölkerung. Die Erkrankung eines Familienmitglieds mit DS beeinflusst Eltern und Geschwister in hohem Maße.
Diskussion: Trotz individueller Kombinationstherapien sind die meisten Patienten mit DS nicht anfallsfrei. Insgesamt hat sich der Einsatz von beim DS wenig wirksamer Medikamente und der kontraindizierten Natriumkanalblocker zugunsten von wirksameren Medikamenten verschoben. Neue Therapie- und Versorgungskonzepte sind notwendig, um die Versorgung der Patienten mit DS zu verbessern und Eltern und Geschwister zu entlasten.
Introduction: Dravet syndrome (DS) is a rare developmental and epileptic encephalopathy. This study estimated cost, cost-driving factors and quality of life (QoL) in patients with Dravet syndrome and their caregivers in a prospective, multicenter study in Germany.
Methods: A validated 3–12-month retrospective questionnaire and a prospective 3-month diary assessing clinical characteristics, QoL, and direct, indirect and out-of-pocket (OOP) costs were administered to caregivers of patients with DS throughout Germany.
Results: Caregivers of 93 patients (mean age 10.1 years, ±7.1, range 15 months–33.7 years) submitted questionnaires and 77 prospective diaries. The majority of patients (95%) experienced at least one seizure during the previous 12 months and 77% a status epilepticus (SE) at least once in their lives. Over 70% of patients had behavioural problems and delayed speech development and over 80% attention deficit symptoms and disturbance of motor skills and movement coordination. Patient QoL was lower than in the general population and 45% of caregivers had some form of depressive symptoms. Direct health care costs per three months were a mean of €6,043 ± €5,825 (median €4054, CI €4935-€7350) per patient. Inpatient costs formed the single most important cost category (28%, €1,702 ± €4,315), followed by care grade benefits (19%, €1,130 ± €805), anti-epileptic drug (AED) costs (15%, €892 ± €1,017) and ancillary treatments (9%, €559 ± €503). Total indirect costs were €4,399 ±€ 4,989 (median €0, CI €3466-€5551) in mothers and €391 ± €1,352 (median €0, CI €195-€841) in fathers. In univariate analysis seizure frequency, experience of SE, nursing care level and severe additional symptoms were found to be associated with total direct healthcare costs. Severe additional symptoms was the single independently significant explanatory factor in a multivariate analysis.
Conclusions: This study over a period up to 15 months revealed substantial direct and indirect healthcare costs of DS in Germany and highlights the relatively low patient and caregiver QoL compared with the general population.
Background: Multiple studies have focused on medical and pharmacological treatments and outcome predictors of patients with status epilepticus (SE). However, a sufficient understanding of recurrent episodes of SE is lacking. Therefore, we reviewed recurrent SE episodes to investigate their clinical characteristics and outcomes in patients with relapses.
Methods: In this retrospective, multicenter study, we reviewed recurrent SE patient data covering 2011 to 2017 from the university hospitals of Frankfurt and Marburg, Germany. Clinical characteristics and outcome variables were compared among the first and subsequent SE episodes using a standardized form for data collection.
Results: We identified 120 recurrent SE episodes in 80 patients (10.2% of all 1177 episodes). The mean age at the first SE episode was 62.2 years (median 66.5; SD 19.3; range 21–91), and 42 of these patients were male (52.5%). A mean of 262.4 days passed between the first and the second episode. Tonic–clonic seizure semiology and a cerebrovascular disease etiology were predominant in initial and recurrent episodes. After subsequent episodes, patients showed increased disability as indicated by the modified Rankin Scale (mRS), and 9 out of 80 patients died during the second episode (11.3%). Increases in refractory and super-refractory SE (RSE and SRSE, respectively) were noted during the second episode, and the occurrence of a non-refractory SE (NRSE) during the first SE episode did not necessarily provide a protective marker for subsequent non-refractory episodes. An increase in the use of intravenous-available anti-seizure medication (ASM) was observed in the treatment of SE patients. Patients were discharged from hospital with a mean of 2.8 ± 1.0 ASMs after the second SE episode and 2.1 ± 1.2 ASMs after the first episode. Levetiracetam was the most common ASM used before admission and on discharge for SE patients.
Conclusions: This retrospective, multicenter study used the mRS to demonstrate worsened outcomes of patients at consecutive SE episodes. ASM accumulations after subsequent SE episodes were registered over the study period. The study results underline the necessity for improved clinical follow-ups and outpatient care to reduce the health care burden from recurrent SE episodes.
