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.
Simple Summary
Seizures are among the most common symptoms of meningioma patients even after surgery. This study sought to identify risk factors for early and late seizures in meningioma patients and to evaluate a modified version of a score to predict postoperative seizures on an independent cohort. The data underline that there are distinct factors identifying patients with a high risk of postoperative seizures following meningioma surgery which has been already shown before. We could further show that the high proportion of 43% of postoperative seizures occur as late seizures which are more dangerous because they may happen out of hospital. The modified STAMPE2 score could predict postoperative seizures when reaching very high scores but was not generally transferable to our independent cohort.
Abstract
Seizures are among the most common symptoms of meningioma. This retrospective study sought to identify risk factors for early and late seizures in meningioma patients and to evaluate a modified STAMPE2 score. In 556 patients who underwent meningioma surgery, we correlated different risk factors with the occurrence of postoperative seizures. A modified STAMPE2 score was applied. Risk factors for preoperative seizures were edema (p = 0.039) and temporal location (p = 0.038). For postoperative seizures preoperative tumor size (p < 0.001), sensomotory deficit (p = 0.004) and sphenoid wing location (p = 0.032) were independent risk factors. In terms of postoperative status epilepticus; sphenoid wing location (p = 0.022), tumor volume (p = 0.045) and preoperative seizures (p < 0.001) were independent risk factors. Postoperative seizures lead to a KPS deterioration and thus an impaired quality of life (p < 0.001). Late seizures occurred in 43% of patients with postoperative seizures. The small sub-cohort of patients (2.7%) with a STAMPE2 score of more than six points had a significantly increased risk for seizures (p < 0.001, total risk 70%). We concluded that besides distinct risk factors, high scores of the modified STAMPE2 score could estimate the risk of postoperative seizures. However, it seems not transferable to our cohort
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.
The COVID-19 pandemic has caused strains on health systems worldwide disrupting routine hospital services for all non-COVID patients. Within this retrospective study, we analyzed inpatient hospital admissions across 18 German university hospitals during the 2020 lockdown period compared to 2018. Patients admitted to hospital between January 1 and May 31, 2020 and the corresponding periods in 2018 and 2019 were included in this study. Data derived from electronic health records were collected and analyzed using the data integration center infrastructure implemented in the university hospitals that are part of the four consortia funded by the German Medical Informatics Initiative. Admissions were grouped and counted by ICD 10 chapters and specific reasons for treatment at each site. Pooled aggregated data were centrally analyzed with descriptive statistics to compare absolute and relative differences between time periods of different years. The results illustrate how care process adoptions depended on the COVID-19 epidemiological situation and the criticality of the disease. Overall inpatient hospital admissions decreased by 35% in weeks 1 to 4 and by 30.3% in weeks 5 to 8 after the lockdown announcement compared to 2018. Even hospital admissions for critical care conditions such as malignant cancer treatments were reduced. We also noted a high reduction of emergency admissions such as myocardial infarction (38.7%), whereas the reduction in stroke admissions was smaller (19.6%). In contrast, we observed a considerable reduction in admissions for non-critical clinical situations, such as hysterectomies for benign tumors (78.8%) and hip replacements due to arthrosis (82.4%). In summary, our study shows that the university hospital admission rates in Germany were substantially reduced following the national COVID-19 lockdown. These included critical care or emergency conditions in which deferral is expected to impair clinical outcomes. Future studies are needed to delineate how appropriate medical care of critically ill patients can be maintained during a pandemic.
Hintergrund
In Anbetracht ihres bedeutenden Potenzials zur Verbesserung der medizinischen Versorgung wird Telemedizin weiterhin zu wenig genutzt. Trotz einiger erfolgreicher Pilotprojekte in den vergangenen Jahren ist insbesondere über die Hindernisse der Etablierung und Verstetigung von Telemedizin wenig bekannt. Diese Studie hatte das Ziel, die Einstellung niedergelassener Neurologen hinsichtlich der Nutzung von Telemedizin in der Epileptologie und resultierende Hinderungsgründe zu verstehen. Gleichzeitig werden mögliche Lösungsansätze präsentiert.
Methoden
Mithilfe eines individuell erstellten 14-Item-Fragebogens befragten wir prospektiv alle Neurologen, die zuvor die Teilnahme an einem transregionalen Telemedizinpilotprojekt im Bereich der Epileptologie abgelehnt oder keine Rückmeldung gegeben hatten, zu Gründen für und gegen den generellen Einsatz von bzw. die Teilnahme an Telemedizin.
Ergebnisse
Von 58 kontaktierten Neurologen antworteten 33 (57 %). Die häufigsten Gründe für die fehlende Nutzung der Telemedizin waren ein vermuteter Zeitmangel oder ein vermuteter zu großer organisatorischer Aufwand (49 %). Zudem wurden Bedenken bezüglich der technischen Ausstattung (30 %) und eine Präferenz für alternative Wege der intersektoralen Kommunikation (30 %) angegeben. Befürchtete Probleme in Bezug auf die Kostenerstattung für telemedizinische Leistungen waren für 27 % ein Hindernis. Neurologen in ländlichen Gebieten waren signifikant häufiger bereit, zunächst eine telemedizinische Konsultation anzufordern, bevor sie eine Überweisung ausstellen (p = 0,006).
Schlussfolgerungen
Die flächendeckende Etablierung von Telemedizinstrukturen ist immer noch durch Hindernisse erschwert, die meist im organisatorischen Bereich liegen. Die bestehenden Herausforderungen im Gesundheitswesen in ländlichen Gebieten sind eine besondere Chance für die Implementierung von Telemedizin. Die meisten Probleme der Telemedizin können gelöst werden, sollten aber bereits bei der Konzeptionierung von Projekten mitbedacht werden, um ihre Verstetigung zu erleichtern.
Pathogenic variants in PRRT2, encoding the proline-rich transmembrane protein 2, have been associated with an evolving spectrum of paroxysmal neurologic disorders. Based on a cohort of children with PRRT2-related infantile epilepsy, this study aimed at delineating the broad clinical spectrum of PRRT2-associated phenotypes in these children and their relatives. Only a few recent larger cohort studies are on record and findings from single reports were not confirmed so far. We collected detailed genetic and phenotypic data of 40 previously unreported patients from 36 families. All patients had benign infantile epilepsy and harbored pathogenic variants in PRRT2 (core cohort). Clinical data of 62 family members were included, comprising a cohort of 102 individuals (extended cohort) with PRRT2-associated neurological disease. Additional phenotypes in the cohort of patients with benign sporadic and familial infantile epilepsy consist of movement disorders with paroxysmal kinesigenic dyskinesia in six patients, infantile-onset movement disorders in 2 of 40 individuals, and episodic ataxia after mild head trauma in one girl with bi-allelic variants in PRRT2. The same girl displayed a focal cortical dysplasia upon brain imaging. Familial hemiplegic migraine and migraine with aura were reported in nine families. A single individual developed epilepsy with continuous spikes and waves during sleep. In addition to known variants, we report the novel variant c.843G>T, p.(Trp281Cys) that co-segregated with benign infantile epilepsy and migraine in one family. Our study highlights the variability of clinical presentations of patients harboring pathogenic PRRT2 variants and expands the associated phenotypic spectrum.
Purpose: To evaluate long-term outcome of three years and treatment patterns of patients suffering from severely drug-refractory epilepsy (SDRE).
Methods: This analysis was population-based and retrospective, with data collected from four million individuals insured by statutory German health insurance. ICD-10 codes for epilepsy (G40*) and intake of anticonvulsants were used to identify prevalent cases, which were then compared with a matched cohort drawn from the population at large. Insurance data were available from 2008 to 2013. Any patient who had been prescribed with at least four different antiepileptic drugs (AEDs) in an 18-month period was defined as an SDRE case.
Results: A total of 769 patients with SDRE were identified. Of these, 19% were children and adolescents; the overall mean age was 42.3 years, 45.4% were female and 54.6% male. An average of 2.7 AEDs per patient was prescribed during the first follow-up year. The AEDs most commonly prescribed were: levetiracetam (53.5%), lamotrigine (41.4%), valproate (41.3%), lacosamide (20.4%), and topiramate (17.8%). During 3-year follow-up, there was an annual rate of hospitalization in the range 42.7 to 55%, which was significantly higher than the 11.6–12.8% (p < 0.001) for the matched controls. Admissions to hospital because of epilepsy ranged between 1.7 and 1.9 per year, with an average duration for each epilepsy-caused hospitalization of 10–11.1 days. The number of comorbidities for SDRE patients was significantly increased compared with the matched controls: depression (28% against 10%), vascular disorders (22% against 5%), and injury rates were also higher (head 16% against 3%, trunk and limbs 16% against 8%). The 3-year mortality rate for SDRE patients was 14% against 2.1% in the matched cohort.
Conclusion: SDRE patients are treated with AED polytherapy for all of the 3-year follow-up period. They are hospitalized more frequently than the general population and show increased morbidity levels and a sevenfold increase in mortality rate over 3 years. Further examination is required of ways in which new approaches to treatment could lead to better outcomes in severely affected patients.
A systematic review on the burden of illness in individuals with tuberous sclerosis complex (TSC)
(2020)
Objective: This review will summarize current knowledge on the burden of illness (BOI) in tuberous sclerosis complex (TSC), a multisystem genetic disorder manifesting with hamartomas throughout the body, including mainly the kidneys, brain, skin, eyes, heart, and lungs.
Methods: We performed a systematic analysis of the available literature on BOI in TSC according to the PRISMA guidelines. All studies irrespective of participant age that reported on individual and societal measures of disease burden (e.g. health care resource use, costs, quality of life) were included.
Results: We identified 33 studies reporting BOI in TSC patients. Most studies (21) reported health care resource use, while 14 studies reported quality of life and 10 studies mentioned costs associated with TSC. Only eight research papers reported caregiver BOI. Substantial BOI occurs from most manifestations of the disorder, particularly from pharmacoresistant epilepsy, neuropsychiatric, renal and skin manifestations. While less frequent, pulmonary complications also lead to a high individual BOI. The range for the mean annual direct costs varied widely between 424 and 98,008 International Dollar purchasing power parities (PPP-$). Brain surgery, end-stage renal disease with dialysis, and pulmonary complications all incur particularly high costs. There is a dearth of information regarding indirect costs in TSC. Mortality overall is increased compared to general population; and most TSC related deaths occur as a result of complications from seizures as well as renal complications. Long term studies report mortality between 4.8 and 8.3% for a follow-up of 8 to 17.4 years.
Conclusions: TSC patients and their caregivers have a high burden of illness, and TSC patients incur high costs in health care systems. At the same time, the provision of inadequate treatment that does not adhere to published guidelines is common and centralized TSC care is received by no more than half of individuals who need it, especially adults. Further studies focusing on the cost effectiveness and BOI outcomes of coordinated TSC care as well as of new treatment options such as mTOR inhibitors are necessary.
Objective: We sought to evaluate the efficacy and tolerability of intranasal midazolam (in‐MDZ) as first‐line inhospital therapy in patients with status epilepticus (SE) during continuous EEG recording.
Methods: Data on medical history, etiology and semiology of SE, anticonvulsive medication usage, efficacy and safety of in‐MDZ were retrospectively reviewed between 2015 and 2018. Time to end of SE regarding the administration of in‐MDZ and ß‐band effects were analyzed on EEG and with frequency analysis.
Results: In total, 42 patients (mean age: 52.7 ± 22.7 years; 23 females) were treated with a median dose of 5 mg of in‐MDZ (range: 2.5–15 mg, mean: 6.4 mg, SD: 2.6) for SE. The majority of the patients suffered from nonconvulsive SE (n = 24; 55.8%). In total, 24 (57.1%) patients were responders, as SE stopped following the administration of in‐MDZ without any other drugs being given. On average, SE ceased on EEG at 05:05 (minutes:seconds) after the application of in‐MDZ (median: 04:56; range: 00:29–14:53; SD:03:13). Frequency analysis showed an increased ß‐band on EEG after the application of in‐MDZ at 04:07 on average (median: 03:50; range: 02:20–05:40; SD: 01:09). Adverse events were recorded in six patients (14.3%), with nasal irritations present in five (11.9%) and prolonged sedation occurring in one (2.6%) patient.
Conclusions: This pharmaco‐EEG–based study showed that in‐MDZ is effective and well‐tolerated for the acute treatment of SE. EEG and clinical effects of in‐MDZ administration occurred within 04:07 and 5:05 on average. Intranasal midazolam appears to be an easily applicable and rapidly effective alternative to buccal or intramuscular application as first‐line treatment if an intravenous route is not available.
Introduction: This study was designed to evaluate risk factors and incidence of epilepsy-related injuries and accidents (ERIA) at an outpatient clinic of a German epilepsy center providing healthcare to a mixed urban and rural population of over one million inhabitants.
Methods: Data acquisition was performed between 10/2013 and 09/2014 using a validated patient questionnaire on socioeconomic status, course of epilepsy, quality of life (QoL), depression, injuries and accidents associated with seizures or inadequate periictal patterns of behavior concerning a period of 3 months. Univariate analysis, multiple testing and regression analysis were performed to identify possible variables associated with ERIA.
Results: A total of 292 patients (mean age 40.8 years, range 18–86; 55% female) were enrolled and analyzed. Focal epilepsy was diagnosed in 75% of the patients. The majority was on an antiepileptic drug (AEDs) polytherapy (mean number of AEDs: 1.65). Overall, 41 patients (14.0%) suffered from epilepsy-related injuries and accidents in a 3-month period. Besides lacerations (n = 18, 6.2%), abrasions and bruises (n = 9, 3.1%), fractures (n = 6, 2.2%) and burns (n = 3, 1.0%), 17 mild injuries (5.8%) were reported. In 20 (6.8% of the total cohort) cases, urgent medical treatment with hospitalization was necessary. Epilepsy-related injuries and accidents were related to active epilepsy, occurrence of generalized tonic-clonic seizures (GTCS) and drug-refractory course as well as reported ictal falls, ictal loss of consciousness and abnormal peri-ictal behavior in the medical history. In addition, patients with ERIA had significantly higher depression rates and lower QoL.
Conclusion: ERIA and their consequences should be given more attention and standardized assessment for ERIA should be performed in every outpatient visit.
