202 Patienten (113 Frauen und 89 Männer im Alter von 25 bis 95 Jahren) mit einem ischämischen, supratentoriellem und territorialen Schlaganfall vorwiegend im Mediastromgebiet, wurden 9/2007 bis 6/2012 aus dem Patientengut der Stroke Unit der Neurologischen Klinik der Universitätsmedizin Greifswald für die monozentrische Studie zur Häufigkeit epileptischer Anfälle sowie ihrer Provokationsfaktoren rekrutiert.
Bei einem durchschnittlichen Beobachtungszeitraum von 36,5 Monaten erlitten 39 Patienten (19,3%) mindestens einen epileptischen Anfall. Davon hatten 12 Patienten einen akut symptomatischen Anfall und 27 einen unprovozierten Anfall. Bei 21 Patienten traten rezidivierende Anfälle auf. Wendet man die aktualisierte Definition der ILAE für Epilepsie an, so hatten 31 (15,3%) Patienten eine Epilepsie und 8 (4%) einen einzelnen akutsymptomatischen Anfall. Damit hatte unsere Studie die bisher höchste dokumentierte Rate an Epilepsie nach einer Ischämie. Der erste epileptische Anfall trat dabei überwiegend im 1. Jahr nach erlittenem Schlaganfall auf. Es zeigte sich, dass Patienten mit einer geringeren Schwere des Schlagfalls (erfasst mittels NIHSSS und mRS) ein geringeres Risiko für die Entwicklung eines epileptischen Anfalls hatten. Alter und Geschlecht zeigten keine Korrelation zum Auftreten eines epileptischen Anfalls.
96 Patienten (53 Frauen und 43 Männer) erhielten innerhalb der ersten 6 h nach dem Schlaganfall eine auswertbare PCT, davon hatten 17 (17,7%) mindestens einen epileptischen Anfall. Mit Hilfe der PCT wurden für die einzelnen Perfusionsparameter CBF, CBF und TTP der ASPECTS, das Perfusionsdefizit und die relativen Perfusionsparameter bestimmt. Bei dem ASPECTS CBF und ASPECTS CBV zeigte sich, dass die vorderen Mantelregionen M1 und M4 bzw. nur M1 bei den Patienten mit einem epileptischen Anfall signifikant häufiger einen geringeren CBF oder ein geringeres CBV hatten. Ein signifikanter Unterschied ergab sich auch beim Betrachtung der Perfusionsdefizite in Bezug auf den CBF und das CBV: Patienten mit einem epileptischer Anfall zeigten ein größeres Perfusionsdefizit als die Patienten ohne epileptischen Anfall. In die relativen Perfusionsparameter fließt neben dem Perfusionsdefizit noch die Infarktgröße ein. Zwar ergab sich kein signifikanter Unterschied zwischen den beiden Gruppen in Bezug auf die Infarktgröße, trotzdem konnte eine Korrelation zwischen einem erniedrigten R[CBF] bzw. einem erniedrigten R[CBV] und dem Auftreten von epileptischen Anfällen nach einem ischämischen Schlaganfall feststellt werden.
Background
There is a lack of data concerning socioeconomic outcome and quality of life (QoL) in patients after status epilepticus (SE) in Germany.
Patients and methods
Adult patients treated between 2011 and 2015 due to SE at the university hospitals in Frankfurt, Greifswald, and Marburg were asked to fill out a questionnaire regarding long-term outcome of at least 3 months after discharge. The SE cohort consisted of 25.9% patients with an acute symptomatic, 42% with a remote symptomatic and previous epilepsy, 22.2% with a new-onset remote symptomatic, and 9.9% with other or unknown etiology. A matched case–control analysis was applied for comparison with patients with drug refractory epilepsy and seizure remission, both not previously affected by SE.
Results
A total of 81 patients (mean age: 58.7 ± 18.0 years; 58% female) participated. A non-refractory course was present in 59.3%, while 27.2% had a refractory SE (RSE) and 13.6% had a superrefractory SE (SRSE). Before admission, a favorable modified Rankin Scale (mRS) of 0–3 was found in 82.7% (67/81), deteriorating to 38.3% (31/81) (p = 0.003) at discharge. The majority returned home [51.9% (42/81)], 32.1% entered a rehabilitation facility, while 12.3% were transferred to a nursing home and 3.7% to another hospital. The overall mRS at follow-up did not change; 61.8% (45/74) reached an mRS of 0–3. In RSE and SRSE, the proportion with a favorable mRS increased from 45.5% at discharge to 70% at follow-up, while QoL was comparable to a non-refractory SE course. Matched epilepsy controls in seizure remission were treated with a lower mean number of anticonvulsants (1.3 ± 0.7) compared to controls with drug refractory epilepsy (1.9 ± 0.8; p < 0.001) or SE (1.9 ± 1.1; p < 0.001). A major depression was found in 32.8% of patients with SE and in 36.8% of drug refractory epilepsy, but only in 20.3% of patients in seizure remission. QoL was reduced in all categories (QOLIE-31) in SE patients in comparison with patients in seizure remission, but was comparable to patients with drug refractory epilepsy.
Discussion
Patients after SE show substantial impairments in their QoL and daily life activities. However, in the long term, patients with RSE and SRSE had a relatively favorable outcome comparable to that of patients with a non-refractory SE course. This underlines the need for efficient therapeutic options in SE.
Background: Granulocytes and monocytes are the first cells to invade the brain post stroke and are also being discussed as important cells in early neuroinflammation after seizures. We aimed at understanding disease specific and common pathways of brain-immune-endocrine-interactions and compared immune alterations induced by stroke and seizures. Therefore, we compared granulocytic and monocytic subtypes between diseases and investigated inflammatory mediators. We additionally investigated if seizure type determines immunologic alterations.
Material and Methods: We included 31 patients with acute seizures, 17 with acute stroke and two control cohorts. Immune cells were characterized by flow cytometry from blood samples obtained on admission to the hospital and the following morning. (i) Monocytes subpopulations were defined as classical (CD14++CD16−), (ii) intermediate (CD14++CD16+), and (iii) non-classical monocytes (CD14dimCD16+), while granulocyte subsets were characterized as (i) “classical granulocytes” (CD16++CD62L+), (ii) pro-inflammatory (CD16dimCD62L+), and (iii) anti-inflammatory granulocytes (CD16++CD62L−). Stroke patient's blood was additionally drawn on days 3 and 5. Cerebrospinal fluid mitochondrial DNA was quantified by real-time PCR. Plasma High-Mobility-Group-Protein-B1, metanephrine, and normetanephrine were measured by ELISA.
Results: HLA-DR expression on monocytes and their subpopulations (classical, intermediate, and non-classical monocytes) was reduced after stroke or seizures. Expression of CD32 was increased on monocytes and subtypes in epilepsy patients, partly similar to stroke. CD32 and CD11b regulation on granulocytes and subpopulations (classical, anti-inflammatory, pro-inflammatory granulocytes) was more pronounced after stroke compared to seizures. On admission, normetanephrine was upregulated in seizures, arguing for the sympathetic nervous system as inducer of immune alterations similar to stroke. Compared to partial seizures, immunologic changes were more pronounced in generalized tonic-clonic seizures.
Conclusion: Seizures lead to immune alterations within the immediate postictal period similar but not identical to stroke. The type of seizures determines the extent of immune alterations.
Objective: To evaluate the efficacy and tolerability of brivaracetam (BRV) in a severely drug refractory cohort of patients with epileptic encephalopathies (EE).
Method: A multicenter, retrospective cohort study recruiting all patients treated with EE who began treatment with BRV in an enrolling epilepsy center between 2016 and 2017.
Results: Forty-four patients (27 male [61%], mean age 29 years, range 6 to 62) were treated with BRV. The retention rate was 65% at 3 months, 52% at 6 months and 41% at 12 months. A mean retention time of 5 months resulted in a cumulative exposure to BRV of 310 months. Three patients were seizure free during the baseline. At 3 months, 20 (45%, 20/44 as per intention-to-treat analysis considering all patients that started BRV including three who were seizure free during baseline) were either seizure free (n = 4; 9%, three of them already seizure-free at baseline) or reported at least 25% (n = 4; 9%) or 50% (n = 12; 27%) reduction in seizures. An increase in seizure frequency was reported in two (5%) patients, while there was no change in the seizure frequency of the other patients. A 50% long-term responder rate was apparent in 19 patients (43%), with two (5%) free from seizures for more than six months and in nine patients (20%, with one [2 %] free from seizures) for more than 12 months. Treatment-emergent adverse events were predominantly of psychobehavioural nature and were observed in 16%.
Significance: In this retrospective analysis the rate of patients with a 50% seizure reduction under BRV proofed to be similar to those seen in regulatory trials for focal epilepsies. BRV appears to be safe and relatively well tolerated in EE and might be considered in patients with psychobehavioral adverse events while on levetiracetam.
Abstract
Objective
This study was undertaken to calculate epilepsy‐related direct, indirect, and total costs in adult patients with active epilepsy (ongoing unprovoked seizures) in Germany and to analyze cost components and dynamics compared to previous studies from 2003, 2008, and 2013. This analysis was part of the Epi2020 study.
Methods
Direct and indirect costs related to epilepsy were calculated with a multicenter survey using an established and validated questionnaire with a bottom‐up design and human capital approach over a 3‐month period in late 2020. Epilepsy‐specific costs in the German health care sector from 2003, 2008, and 2013 were corrected for inflation to allow for a valid comparison.
Results
Data on the disease‐specific costs for 253 patients in 2020 were analyzed. The mean total costs were calculated at €5551 (±€5805, median = €2611, range = €274–€21 667) per 3 months, comprising mean direct costs of €1861 (±€1905, median = €1276, range = €327–€13 158) and mean indirect costs of €3690 (±€5298, median = €0, range = €0–€11 925). The main direct cost components were hospitalization (42.4%), antiseizure medication (42.2%), and outpatient care (6.2%). Productivity losses due to early retirement (53.6%), part‐time work or unemployment (30.8%), and seizure‐related off‐days (15.6%) were the main reasons for indirect costs. However, compared to 2013, there was no significant increase of direct costs (−10.0%), and indirect costs significantly increased (p < .028, +35.1%), resulting in a significant increase in total epilepsy‐related costs (p < .047, +20.2%). Compared to the 2013 study population, a significant increase of cost of illness could be observed (p = .047).
Significance
The present study shows that disease‐related costs in adult patients with active epilepsy increased from 2013 to 2020. As direct costs have remained constant, this increase is attributable to an increase in indirect costs. These findings highlight the impact of productivity loss caused by early retirement, unemployment, working time reduction, and seizure‐related days off.
