Predictors for and use of rescue medication in adults with epilepsy: A multicentre cross-sectional study from Germany.

BACKGROUND: Seizure clusters, prolonged seizures, and status epilepticus are life-threatening neurological emergencies leading to irreversible neuronal damage. Benzodiazepines are current evidence-based rescue therapy options; however, recent investigations indicated the prescription of mainly unsuitable benzodiazepines and inappropriate use of rescue medication. OBJECTIVE: To examine current use, satisfaction, and adverse events concerning rescue medication in patients with epilepsy in Germany. PATIENTS AND METHODS: The study was conducted at epilepsy centres in Frankfurt am Main, Greifswald, Marburg, and Münster between 10/2020 and 12/2020. Patients with an epilepsy diagnosis were assessed based on a questionnaire examining a 12-month period. RESULTS: In total, 486 patients (mean age: 40.5, range 18-83, 58.2 % female) participated in this study, of which 125 (25.7 %) reported the use of rescue medication. The most frequently prescribed rescue medications were lorazepam tablets (56.8 %, n = 71 out of 125), buccal midazolam (19.2 %, n = 24), and rectal diazepam (10.4 %, n = 13). Seizures continuing for over several minutes (43.2 %, n = 54), seizure clusters (28.0 %, n = 35), and epileptic auras (28.0 %, n = 35) were named as indications, while 28.0 % (n = 35) stated they administered the rescue medication for every seizure. Of those continuing to have seizures, 46.0 % did not receive rescue medication. On average, rescue medication prescription occurred 7.1 years (SD 12.7, range 0-66) after an epilepsy diagnosis. CONCLUSIONS: Unsuitable oral benzodiazepines remain widely prescribed for epilepsy patients as rescue medication. Patients also reported inappropriate use of medication. A substantial proportion of patients who were not seizure-free did not receive rescue medication prescriptions. Offering each patient at risk for prolonged seizures or clusters of seizures an individual rescue treatment with instructions on using it may decrease mortality and morbidity and increase quality of life. .

Determinants of quality of life in adults with epilepsy: a multicenter, cross-sectional study from Germany.

BACKGROUND: Assessment of quality of life (QoL) has become an important indicator for chronic neurological diseases. While these conditions often limit personal independence and autonomy, they are also associated with treatment-related problems and reduced life expectancy. Epilepsy has a tremendous impact on the QoL of patients and their families, which is often underestimated by practitioners. The aim of this work was to identify relevant factors affecting QoL in adults with epilepsy. METHODS: This cross-sectional, multicenter study was conducted at four specialized epilepsy centers in Germany. Patients diagnosed with epilepsy completed a standardized questionnaire focusing on QoL and aspects of healthcare in epilepsy. Univariate regression analyses and pairwise comparisons were performed to identify variables of decreased QoL represented by the overall Quality of Life in Epilepsy Inventory (QOLIE-31) score. The variables were then considered in a multivariate regression analysis after multicollinearity analysis. RESULTS: Complete datasets for the QOLIE-31 were available for 476 patients (279 [58.6%] female, 197 [41.4%] male, mean age 40.3 years [range 18-83 years]). Multivariate regression analysis revealed significant associations between low QoL and a high score on the Liverpool Adverse Events Profile (LAEP; beta=-0.28, p < 0.001), Hospital Anxiety and Depression Scale - depression subscale (HADS-D; beta=-0.27, p < 0.001), Neurological Disorders Depression Inventory in Epilepsy (NDDI-E; beta=-0.19, p < 0.001), revised Epilepsy Stigma Scale (beta=-0.09, p = 0.027), or Seizure Worry Scale (beta=-0.18, p < 0.001) and high seizure frequency (beta = 0.14, p < 0.001). CONCLUSION: Epilepsy patients had reduced QoL, with a variety of associated factors. In addition to disease severity, as measured by seizure frequency, the patient's tolerability of anti-seizure medications and the presence of depression, stigma, and worry about new seizures were strongly associated with poor QoL. Diagnosed comorbid depression was underrepresented in the cohort; therefore, therapeutic decisions should always consider individual psychobehavioral and disease-specific aspects. Signs of drug-related adverse events, depression, fear, or stigmatization should be actively sought to ensure that patients receive personalized and optimized treatment.

Gender differences in concerns about planning to have children and child-rearing among patients with epilepsy: A prospective, multicenter study with 477 patients from Germany.

OBJECTIVE: To analyze the concerns and worries about planning to have children and being a parent as a person with epilepsy and investigate gender differences in these perceptions. METHODS: The Epi2020 study was a large multicenter study focusing on different healthcare aspects of adult patients with epilepsy in Germany. In addition to basic clinical and demographic characteristics, patients were asked to answer a questionnaire regarding their plan to have children, if they had children, and concerns about their children's health. Data were analyzed to detect differences between men and women with epilepsy according to age group. RESULTS: In total, 477 patients with epilepsy with a mean age of 40.5 years (SD = 15.5, range: 18-83 years) participated in this study; 280 (58.7%) were female and 197 (41.3%) were male. Both women and men frequently reported concerns and worries about having children: In the age group below 45 years of age, 72.5% of women and 58.2% of men described being worried to some extent that their children may also suffer from epilepsy (p = .006). Furthermore, 67.3% of women and 54.2% of men below the age of 45 years reported being worried that their children may be disabled (p = .003). Women were more likely to have family members who are reluctant to support their desire to have children (p = .048). CONCLUSION: Women with epilepsy of childbearing age are significantly more likely to report major concerns that their children might be disabled or also have epilepsy than men with epilepsy and, therefore, express more concerns about choosing to have a child. However, men also report frequent concerns and worries, and this should be addressed not only on request but should be included in the provision of general information on epilepsy.

Prevalence and outcome of late-onset seizures due to autoimmune etiology: A prospective observational population-based cohort study.

OBJECTIVE: The increasing incidence of new-onset seizures with age is well known. Often, the etiology cannot be clarified. In the present study, patients with unprovoked late-onset seizures and without known neoplasm, who might have had paraneoplastic encephalitis, were investigated for a potentially underlying autoimmunity. METHODS: Sixty-six consecutive patients (36 women; aged ≥55 years) after having at least one seizure or seizures for ≤6 months were prospectively identified over a period of 4.75 years. All patients were tested for serum and cerebrospinal fluid (CSF) antibodies (Abs) to both neural cell-surface and intracellular antigens. Forty-five (68%) underwent brain magnetic resonance imaging (MRI). Follow-up in Ab-positive cases was ≥6 months. RESULTS: Two patients had high titers of anti-CASPR2 (contactin-associated protein-like 2) Abs in serum and CSF and fulfilled the diagnostic criteria of definite limbic encephalitis. Another two patients had bilateral encephalitic temporal MRI abnormalities. They also satisfied the criteria of definite limbic encephalitis, even though they had no Abs in serum or CSF. All four were in the age range of 55-70 years. They received immunotherapy and/or antiepileptic drug treatment and became seizure-free. SIGNIFICANCE: Our findings suggest that autoimmunity should be considered an important etiology in patients with late-onset seizures. Testing for neural antibodies and brain MRI may be worthwhile in this patient group.

Treatment of refractory and super-refractory status epilepticus with brivaracetam: A cohort study from two German university hospitals.

PURPOSE: We aimed to ascertain the possible use of brivaracetam (BRV) as an option for treatment of status epilepticus (SE). METHODS: A review of medical records was carried out to detect BRV administration in SE patients treated in Frankfurt and Greifswald during the period February 2016 to January 2017. The primary outcome question concerned SE resolution after BRV initiation. RESULTS: During that period, BRV was started with eleven adult patients with SE. Five of these were female, and the median age was 64 (interquartile range [IQR] 21years). The median SE duration before BRV initiation was 5days (IQR 9days); the median number of previous anticonvulsants used was 4 (IQR 5). Initial BRV doses ranged between 50mg and 400mg (median 100mg), titrated to a daily dose of 100 to 400mg (median 200mg). There was a cessation of SE in the first 24h of BRV in three patients (27%). While taking BRV, no serious side effects were seen. CONCLUSION: Based on these cases and previous data from animal experiments, BRV may prove useful in SE treatment, and trials would be warranted to examine BRV's efficacy in treating SE and how this efficacy might be influenced by co-administration with levetiracetam.

Predictive value of EFHC1 variants for the long-term seizure outcome in juvenile myoclonic epilepsy.

OBJECTIVE: This study aimed to determine the contribution of EFHC1 variants to the phenotypic variability of juvenile myoclonic epilepsy (JME) and to evaluate their diagnostic value regarding previously identified clinical long-term seizure outcome predictors in a consecutive cohort of patients with JME. METHODS: Thirty-eight probands and three family members affected with JME were studied at a tertiary epilepsy center with a review of their medical records and a subsequent face-to-face interview. All coding EFHC1 exons and adjacent exon/intron boundaries were directly sequenced. RESULTS: The previously reported EFHC1 mutation F229L was found in two cases who presented with early generalized tonic-clonic seizure (GTCS) onset and appeared to be associated with milder subtypes of JME. Variant R294H was identified in two further probands who had a subtype of JME developing from childhood absence epilepsy. However, segregation of the phenotype with this variant could not be confirmed in one family. CONCLUSIONS: Our findings corroborate the heterogeneity of JME as an electroclinical epilepsy syndrome and provide evidence that genetic factors may influence and help predict the long-term seizure outcome in patients with JME.

Stroke alters respiratory burst in neutrophils and monocytes.

BACKGROUND AND PURPOSE: Stroke-induced immune alterations predispose patients to infections. Although the relationship between stroke and the adaptive immune system has been investigated in detail, to date it is unknown whether the innate immune system, which forms the first line of antibacterial defense, is also impaired in patients with stroke. Therefore, we investigated whether chemotaxis, phagocytosis, oxidative burst, degranulation of defensins, and NETosis in monocytes and in neutrophil granulocytes are altered in patients with stroke compared with controls. METHODS: Sixty-three patients having acute ischemic stroke were recruited within 12 hours of symptom onset; blood was sampled on admission and on days 1, 3, 5, and 7. Thirty-seven age-matched controls were also recruited. Cell migration, phagocytosis, and oxidative burst of phagocytes were determined in vitro. Human neutrophil peptides 1 to 3 and serum metanephrine levels were measured by enzyme-linked immunosorbent assay, and NETosis was quantified by immunohistochemistry. RESULTS: The key mechanisms required for bacterial killing, oxidative burst, and NETosis were significantly reduced in samples taken from patients with stroke compared with controls, whereas migration, phagocytic function, and defensin production remained unimpaired in monocytes and granulocytes from patients with stroke. CONCLUSIONS: Stroke-induced immune alterations include impairment of the first-line defense performed by specialized phagocytes against bacteria. The hypothesis that these changes enhance susceptibility to acquired infections is supported by our observation that on admission oxidative burst in monocytes was more impaired in patients with stroke with subsequent stroke-associated infections.
