Abstract
Background Epilepsy is one of the most common and disabling neurological disorders. It is highly prevalent in children with neurodevelopmental delay and syndromic diseases. However, epilepsy can also be the only disease-determining symptom. The exact molecular diagnosis is essential to determine prognosis, comorbidity, and probability of recurrence, and to inform therapeutic decisions. Methods and materials Here, we describe a prospective cohort study of patients with epilepsy evaluated in seven diagnostic outpatient centers in Germany. Over a period of 2 months, 07/2022 through 08/2022, 304 patients (317 returned result) with seizure-related human phenotype ontology (HPO) were analyzed. Evaluated data included molecular results, phenotype (syndromic and non-syndromic), and sequencing methods. Results Single exome sequencing (SE) was applied in half of all patients, followed by panel (P) testing (36%) and trio exome sequencing (TE) (14%). Overall, a pathogenic variant (PV) (ACMG cl. 4/5) was identified in 22%; furthermore, a significant number of patients (12%) carried a reported clinically meaningful variant of unknown significance (VUS). The average diagnostic yield in patients ≤ 12 y was higher compared to patients >12 y cf. Figure 2B vs. Figure 3B. This effect was more pronounced in cases, where TE was applied in patients ≤ 12 vs. >12 y [PV (PV + VUS): patients ≤ 12 y: 35% (47%), patients > 12 y: 20% (40%)]. The highest diagnostic yield was achieved by TE in syndromic patients within the age group ≤ 12 y (ACMG classes 4/5 40%). In addition, TE vs. SE had a tendency to result in less VUS in patients ≤ 12 y [SE: 19% (22/117) VUS; TE: 17% (6/36) VUS] but not in patients >12 y [SE: 19% (8/42) VUS; TE: 20% (2/10) VUS]. Finally, diagnostic findings in patients with syndromic vs. non-syndromic symptoms revealed a significant overlap of frequent causes of monogenic epilepsies, including SCN1A, CACNA1A, and SETD1B, confirming the heterogeneity of the associated conditions. Conclusion In patients with seizures-regardless of the detailed phenotype-a monogenic cause can be frequently identified, often implying a possible change in therapeutic action (36.7% (37/109) of PV/VUS variants); this justifies early and broad application of genetic testing. Our data suggest that the diagnostic yield is highest in exome or trio-exome-based testing, resulting in a molecular diagnosis within 3 weeks, with profound implications for therapeutic strategies and for counseling families and patients regarding prognosis and recurrence risk.

Epilepsy Behav 2023; 138:108982. [PMID: 36459812 DOI: 10.1016/j.yebeh.2022.108982] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Revised: 10/24/2022] [Accepted: 10/29/2022] [Indexed: 11/30/2022]
Abstract
OBJECTIVE In Germany, six previous representative surveys on attitudes toward epilepsy (AE) have been conducted between 1967 and 2008 using the four original Caveness questions (CQs) from 1949 to 1980. The aims of this study were (1) to investigate changes in AE over the time span of 50 years, including the current survey in 2018 (2) to investigate the first-time emotional reactions measured with the Scales of Attitudes toward People with Epilepsy (SAPE) (3) to identify predictors of AE. METHODS A representative face-to-face survey with CQ, in addition with the SAPE scales of Social Distance, Stereotypes, Personal Concerns, and Emotional Reactions was carried out in Germany in 2018. One thousand and twenty-six persons who ever had heard of epilepsy participated. Respondents who answered "don't know" in the CQs were subsequently asked to answer only yes/no. The analysis of trends from 1967 to 2018 was based on the pooled data of the surveys. The four CQs in the 2018 survey were included in the SAPE item pool and an exploratory principal axis factor analysis was performed. General linear models were performed to identify predictors. RESULTS For all four CQs, the trend of improved AE was significant over the past 50 years. In the 2018 survey, excluding the "don't know" answer option increased the proportion of negative responses for contact of one's own children with a person with epilepsy (PWE) from 6.9% to 11.4% and for the marriage of one's own children with a PWE from 13.9% to 23.8%. When encountering a PWE, 30.1% would feel insecure or uncomfortable and nearly 60% were concerned that the PWE might be injured in case of a seizure. Knowing what to do in case of a seizure, knowing that seizures can be treated successfully, personal contact with a PWE along with younger age, and higher education were found to be the strongest predictors for positive AE identified by multivariate analyses. Exploratory principal axis factor analysis revealed that three of the four CQs items loaded > 0.30 at the factors of Social Distance and Stereotypes of SAPE but none on the factors measuring emotional reactions. SIGNIFICANCE AE measured by CQs have markedly improved in Germany over the last 50 years. Germany is to our knowledge the only country with such a long-term trend investigation in AE. Negative AE may be underestimated by survey questions with "don't know" answer option. Emotional aspects of attitudes are underexposed resp. neglected in the CQs, which are used worldwide for measuring AE. Additional tools like SAPE can close this gap. The identified predictors may help to derive interventions against negative AE.

Epilepsy Behav 2022; 135:108910. [PMID: 36115082 DOI: 10.1016/j.yebeh.2022.108910] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Revised: 08/30/2022] [Accepted: 09/02/2022] [Indexed: 11/03/2022]
Abstract
PURPOSE The aim of this retrospective study was to analyze the incidence of lower urinary tract infections (LUTI) and antibiotic prescriptions within 12 months after initial prescription of anti-seizure medication (ASM) between January and December 2020 (index date) and to investigate the association between a broad spectrum of ASMs and the risk of LUTI in patients with epilepsy. METHODS This retrospective cohort study included a total of 9186 adult patients (≥18 years) with an initial diagnosis of epilepsy and a prescription of an ASM treated in 1284 general practices in Germany between January 2010 and December 2020 (index date). Six frequently prescribed ASMs with at least 1000 available patients were analyzed. Patients treated with one of six ASMs were matched to each other by propensity scores based on sex, age, and secondary diagnoses. Cox regression models were used to analyze the association between the use of ASM and LUTI risk. RESULTS The cumulative LUTI incidence 12 months after the start of therapy was highest in patients treated with pregabalin (16.7%), followed by valproate (11.6%) and gabapentin (10.2%). A similar trend was observed for LUTI with antibiotic prescription (9.2% pregabalin, 6.8% valproate, 6.8% gabapentin). Conditional regression analyses revealed that pregabalin therapy was significantly positively associated with LUTI (HR: 1.76; 95% CI 1.29-2.39) and LUTI-based antibiotic prescription (HR: 2.16; 95% CI 1.43-3.27). Carbamazepine was associated with a significantly lower incidence of LUTI in women (HR: 0.47; 95% CI: 0.30-0.75), but not in men. No significant associations were observed for other ASMs. CONCLUSION The present study identifies a significant positive association between ASM and LUTI incidence and antibiotic prescriptions in patients with epilepsy treated with pregabalin, whereas a protective effect was found for carbamazepine in women only. No significant associations were observed for the four remaining ASMs.

Effects of a specialized inpatient treatment program on epilepsy-related impairments of patients with epilepsy and intellectual disability as rated by relatives and professional caregivers. Epilepsy Behav 2021; 117:107809. [PMID: 33639437 DOI: 10.1016/j.yebeh.2021.107809] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2020] [Accepted: 01/18/2021] [Indexed: 11/26/2022]
Abstract
INTRODUCTION The aim of the study was to determine the impact of a comprehensive inpatient treatment program for persons with epilepsy and intellectual disability (ID) on the concerns of relatives and caregivers, quality of life (QoL), and global health and clinical aspects, assessed by a questionnaire for relatives and caregivers. METHODS We performed an open, controlled pre/post study in inpatients with epilepsy and ID or acquired brain damage treated for at least 14 days in a tertiary referral center for epilepsy. Questionnaires were administered to relatives/professional caregivers shortly before admission and 6 months after discharge for the treatment group (TG). The control group (CG) was recruited from the waiting list; questionnaires were answered at the time of application for treatment and 3-6 months later. The questionnaire was the GEOS-43G, the German version of the Glasgow Epilepsy Outcome Scale (GEOS-35), which was extended by eight additional questions from the GEOS-90. Furthermore, QoL, global health, and clinical aspects were assessed using a short questionnaire. Generalized estimation equations (GEEs) were used for statistical analyses. RESULTS One-hundred and eight subjects were evaluable in the TG, and 90 in the CG. Concerns about seizures, injuries/risks, medical treatment, diagnostic issues, and the GEOS-43G total score decreased significantly in the TG in contrast to the CG. For the TG, improvements were also significant for global QoL, global health, efficacy, tolerability of AEDs, and for seizure frequency. Caregivers reported larger improvements compared to relatives. CONCLUSION The evaluation of the relatives and caregivers in our study indicates that inpatient treatment in a specialized center with a dedicated multi-professional program led to significant improvements regarding the concerns of relatives or caregivers, and in the QoL and related aspects in persons with epilepsy and ID. This shows that specialized inpatient treatment may be helpful for persons with epilepsy and ID.

Abstract
ZusammenfassungEpilepsiepatienten leiden überdurchschnittlich häufig unter Kopfschmerzen. Dies gilt insbesondere für Patienten mit idiopathisch generalisierten und parietookzipitalen Epilepsien. Die Häufigkeit des gemeinsamen Auftretens von Kopfschmerzen und Epilepsie überschreitet dabei die rechnerische Koinzidenz, sodass von einer Komorbidität beider Syndrome auszugehen ist. Bestärkt wird diese Hypothese durch überlappende genetische Veränderungen sowie gemeinsame pathophysiologische Mechanismen. Bis zu 62 % der Patienten mit z. B. Parietal- und Okzipitallappenepilepsie (POLE) geben Kopfschmerzen an. Diese treten v. a. nach dem Anfall (postiktal) auf und manifestieren sich am häufigsten als Migräne-ähnlicher Kopfschmerz oder Spannungskopfschmerz. Seltener kommt es zu Kopfschmerzen vor (periiktal), während (iktal) oder zwischen (interiktal) epileptischen Anfällen. Bei transienten neurologischen Ausfallsymptomen mit begleitenden Kopfschmerzen ist differenzialdiagnostisch neben der Migräne an vaskuläre Ereignisse wie Synkopen oder eine transiente ischämische Attacke zu denken.
