ABSTRACT

BACKGROUND: Epilepsy contributes to high morbidity among children and adolescents in developing countries. A quarter of all children with epilepsy will be resistant to anti-seizure medications (ASMs), with associated neurocognitive impairments and risk of higher mortality. This study aimed to estimate and characterize drug-resistant epilepsy (DRE) (defined as failure to achieve sustained remission after adequate trials of two tolerated and appropriately chosen ASMs) and its associated factors among children and adolescents with epilepsies attending the pediatric neurology clinic at Muhimbili National Hospital (MNH), Dar es Salaam Tanzania. METHODS: This cross-sectional study was conducted from June 2020 to June 2021. Children with epilepsies and who had been treated with ASMs for at least 3 months were eligible for inclusion. Exclusion criteria included children whose caregivers denied consent and those who exhibited acute medical conditions necessitating admission on the scheduled visit day. Data on demographic characteristics, perinatal history, detailed history of the seizures semiology, drug history, magnetic resonance imaging (MRI), and electroencephalography (EEG) results were obtained from caregivers and medical records available during recruitment. Seizures and epilepsies were classified using the 2017 International League Against Epilepsy (ILAE) classification. Logistic regression was used to determine factors associated with DRE. RESULTS: A total of 236 children and adolescents aged between 4 months and 15 years (Median age 72 months (IQR = 42-78)) were enrolled in this study. We found the proportion of DRE to be 14.8% in this cohort. Of the thirty-five patients with DRE, 60% had generalized epilepsy and almost 25% had a diagnosis of an epilepsy syndrome, the most common being Lennox-Gastaut syndrome (LGS). Structural abnormalities on brain MRI were seen in almost 80% of all patients with DRE, the most prevalent being cystic encephalomalacia, which was observed in 34% of patients. Patients using both ASMs and alternative therapies accounted for 9% of this cohort. The onset of seizures during the first month of life (aOR = 1.99; 95%CI 1.7-4.6; p = 0.031) and high initial seizure frequency (aOR = 3.6; 95%CI 1.6-8;p = 0.002) were found to be independently associated with DRE. CONCLUSION: The proportion of DRE in Tanzania is high. Patients with neonatal onset seizures and high initial seizure frequency should be followed up closely to ensure early diagnosis of DRE.

ABSTRACT

BACKGROUND: For over two decades, a daily folic acid (FA) supplementation has been recommended for women of childbearing age with epilepsy. This recommendation is based on evidence that FA administration before conception and during pregnancy can decrease the risk of fetal malformations in the general population, improve cognitive development, and reduce the risk of autistic traits in children exposed in utero to antiepileptic drugs (AEDs). OBJECTIVE: The aim of this study was to evaluate FA supplementation rate in nonpregnant women of childbearing age with epilepsy and its relation to AED type and number. METHODS: We retrospectively reviewed the computerized database and the medical records of all the women who had a first visit to our outpatient epilepsy clinic (Shamir-Assaf Harofeh Medical Center, Zerifin, Israel) during a 10-year period (2012-2021). RESULTS: Only 61 (22%) of 282 nonpregnant women of childbearing age with epilepsy treated with AEDs received FA supplementation. Ninety-two (33%) of the women were treated with AED polytherapy, and 41 (15%) received valproic acid in monotherapy or polytherapy. FA supplementation rate was higher in women aged ≤40 versus >40 (25% vs. 8.5%) (p = .004). No correlation was found between FA supplementation and AED type or number. CONCLUSIONS: FA supplementation rate was low and was unaffected by AED treatment. Patient and physician-targeted interventions should be implemented to increase FA prescription and patient adherence.

ABSTRACT

OBJECTIVE: Approximately 150,000 Canadian women live with epilepsy, a population that presents with unique challenges. Our objective was to capture demographic and real-world practice characteristics of Canadian healthcare professionals providing care for women with epilepsy (WWE) with specific focus on reproductive considerations to identify potential gaps in knowledge and care. METHODS: A questionnaire developed by the Canadian League Against Epilepsy WWE workgroup was distributed to Canadian healthcare professionals from February 2021 to October 2022 to capture participant demographic characteristics and practice patterns in key areas of the reproductive cycle in WWE. RESULTS: A total of 156 participants completed the questionnaire, most being physicians (81.4%), epilepsy specialists (69.0%), and those who cared for adult patients (86.5%), with a significant proportion based at an academic center (65.4%). The majority of participants counselled on folic acid supplementation (89.7%). Participants selected lamotrigine and levetiracetam most frequently for either focal or generalized epilepsies during pregnancy. Additionally, 85.9% performed therapeutic drug monitoring during pregnancy. Almost all practitioners always or often counseled WWE on valproic acid on the benefits of switching to a less teratogenic medication (96.2%). Some geographic variability in practice patterns was noted with valproic acid being one of the top three medications selected for patients with generalized epilepsies in Western regions, although participants in Eastern regions had brivaracetam more commonly included as one of their top three agents for this population. SIGNIFICANCE: This is the first report of real-world Canadian practices in epilepsy care for women in pregnancy. Overall, our study reports that Canadian practice patterns conform well to current evidence and best-practice guidelines. Important variations in antiseizure medication selection across different regions were identified.

ABSTRACT

BACKGROUND: Previous studies have reported inconsistent results regarding the potential relationships between addictive behaviors and the risk of epilepsy. OBJECTIVE: To assess whether genetically predicted addictive behaviors are causally associated with the risk of epilepsy outcomes. METHODS: The causation between five addictive behaviors (including cigarettes per day, alcoholic drinks per week, tea intake, coffee intake, and lifetime cannabis use) and epilepsy was evaluated by using a two-sample Mendelian Randomization (MR) analysis. The inverse-variance weighted (IVW) method was used as the primary outcome. The other MR analysis methods (MR Egger, weighted median, simulation extrapolation corrected MR-Egger, and Mendelian Randomization Pleiotropy Residual Sum and Outlier (MR-PRESSO)) were performed to complement IVW. In addition, the robustness of the MR analysis results was assessed by leave-one-out analysis. RESULTS: The IVW analysis method indicated an approximately 20% increased risk of epilepsy per standard deviation increase in lifetime cannabis use (odds ratio [OR], 1.20; 95% confidence interval [CI]), 1.02-1.42, P = 0.028). However, there is no causal association between the other four addictive behaviors and the risk of epilepsy (cigarettes per day: OR, 1.04; 95% CI, 0.92-1.18, P = 0.53; alcoholic drinks per week: OR, 1.31; 95% CI, 0.93-1.84, P = 0.13; tea intake: OR, 1.15; 95% CI, 0.84-1.56, P = 0.39; coffee intake: OR, 0.86; 95% CI, 0.59-1.23, P = 0.41). The other MR analysis methods and further leave-one-out sensitivity analysis suggested the results were robust. CONCLUSION: This MR study indicated a potential genetically predicted causal association between lifetime cannabis use and higher risk of epilepsy. As for the other four addictive behaviors, no evidence of a causal relationship with the risk of epilepsy was found in this study.

ABSTRACT

PURPOSE: Epilepsy is a stigmatizing disorder and its diagnosis can have important psychosocial consequences on individuals, severely impacting their quality of life(QOL). There are numerous studies which have seen an adverse impact on the psychosocial aspects of life in patients with intractable epilepsy. The aim of this study was to assess the QOL in adult and adolescent patients with JME, which is largely a well-controlled form of epilepsy. METHODOLOGY: This was a hospital based cross-sectional observational study comprising of 50 JME patients. QOLIE-31-P and QOLIE-AD-48 questionnaires were used to assess QOL in adults & adolescents(11-17 years) respectively. The Mini international neuropsychiatric interview-version 7.0.2 and Brief psychiatric rating scale were used for screening of underlying psychopathology and if, the screening tests were positive then they were further evaluated and classified using DSM V and ICD 10. RESULTS: The mean QOLIE-31-P score was 64.65 ± 15.74. Majority of the adult patients had fair QOL (poor, fair and good QOL scores in 18 %, 54 % and 28 % respectively). Subscale scores in poor category were for the medication effects and pertaining to seizure worry.Among adolescent patients, the mean QOLIE 48 AD score was 69.15 ± 13.13. 50 % had fair QOL. Amongst those with poor QOL, majority of poor scores were for the attitude towards epilepsy. The QOL scores were significantly poorer in patients with uncontrolled seizures. 78 % of the patients had comorbid anxiety and depression, however syndromic psychiatric diagnosis was seen in 10.25 % and 2.56 % for anxiety and depression respectively. Presence of psychiatric symptoms did not influence QOL scores. CONCLUSION: QOL, in well controlled JME, is fair in majority of patients. QOL might improve if seizure worry is addressed and patients are educated about medication effects at the time of initial diagnosis. Vast majority of patients may experience minor psychiatric issues, which do need addressal for formulating a holistic and individualized treatment plan.

ABSTRACT

INTRODUCTION: People living with epilepsy suffer from stigmatization, overprotection, or exclusion, thus, part of these population in developing countries uses traditional medicine as a first resort. METHODS: We prospectively conducted a study to determine the knowledge, attitudes, and practices (KAP) of traditional healers (THs) concerning epilepsy. Over a 9-month period, we included 208 THs practicing in the Littoral, Center and West regions of Cameroon who agreed to participate in the study. The THs were interviewed using a standardized questionnaire. Data were analyzed using Epi Info version 7.2 software. RESULTS: Two-hundred and eight THs were recruited, with a mean age ± standard deviation (SD) of 49.9 ± 11.4 years, and 169 (81.2%) were male. Primary 77(37.0%) and secondary 67(32.2%) levels of education were the most represented, and most of the THs had more than 10 years of professional experience. One hundred and forty-one TH (68,7%) had poor knowledge about epilepsy. The independent factors associated with poor knowledge were female sex, Muslim religion, and marital status of cohabitation. One hundred and eighty-four THs (88.4%) had a good attitude and practices toward people with seizures. Factors independently associated with poor practices and attitude were rural residence, Muslim religion, and education level. CONCLUSION: Our result confirmed that THs had poor knowledge about epilepsy but good attitudes and practices about epilepsy. THs were in favor of future collaboration with modern medicine in the care of people living with epilepsy.

ABSTRACT

OBJECTIVE: The present study was aimed at investigating the effects of anti-seizure medications (ASMs), patient demographic characteristics, and the seizure type and frequency on the development of congenital malformations (CMs) in the infants of pregnant women with epilepsy (PWWE). METHODS: PWWE followed up at the neurology outpatient clinic of 21 centers between 2014 and 2019 were included in this prospective study. The follow-up of PWWE was conducted using structured, general pregnant follow-up forms prepared by the Pregnancy and Epilepsy Study Committee. The newborns were examined by a neonatologist after delivery and at 1 and 3 months postpartum. RESULTS: Of the infants of 759 PWWE, 7.2% had CMs, with 5.6% having major CMs. Polytherapy, monotherapy, and no medications were received by 168 (22.1%), 548 (72.2 %), and 43 (5.7 %) patients, respectively. CMs were detected at an incidence of 2.3% in infants of PWWE who did not receive medication, 5.7% in infants of PWWE who received monotherapy, and 13.7% in infants of PWWE who received polytherapy. The risk of malformation was 2.31-fold (95% confidence interval (CI): 1.48-4.61, p < .001) higher in infants of PWWE who received polytherapy. Levetiracetam was the most frequently used seizure medication as monotherapy, with the highest incidence of CMs occurring with valproic acid (VPA) use (8.5%) and the lowest with lamotrigine use (2.1%). The incidence of CMs was 5% at a carbamazepine dose <700 mg, 10% at a carbamazepine dose ≥700 mg, 5.5% at a VPA dose <750 mg, and 14.8% at a VPA dose ≥750 mg. Thus the risk of malformation increased 2.33 times (p = .041) in infants of PWWE receiving high-dose ASMs. SIGNIFICANCE: Birth outcomes of PWWE receiving and not receiving ASMs were evaluated. The risk of CMs occurrence was higher, particularly in infants of PWWE using VPA and receiving polytherapy. The incidence of CMs was found to be lower in infants of PWWE receiving lamotrigine.

ABSTRACT

BACKGROUND: Complementary and alternative medicine (CAM) consists of various medical practices and products not recognized as a part of conventional medicine. There are few studies on CAMs used for childhood epilepsy. We aimed to determine the prevalence and socio-demographic factors affecting CAM use in children with epilepsy. METHODS: This is a cross-sectional prospective descriptive study. The study included all parents who agreed to participate and had children with epilepsy. The data was collected using a questionnaire developed from a literature review of CAM use in pediatric epilepsy patients. RESULTS: A total of 219 parent-child pairs were included in the study. Seventy-five participants had one or more comorbid disorders. 55.3% of participating children with epilepsy were taking more than one antiseizure medication (ASM). 30.1% of parents reported using some form of CAM for their children in the previous year. Only 60.6% of parents discussed their CAM decision with their child's doctor before using it. Univariate analysis showed that the patient's age, presence of comorbid disorders, duration of ASM, and family history of epilepsy were statistically significant predictors for CAM use. However, the presence of comorbidities was the only significant predictor of CAM use in logistic regression. CONCLUSION: Even though most parents believe CAMs have no effect on their children with epilepsy, they frequently use them. We propose that the predictors identified in this study can help to identify potential CAM users. Since most parents do not report the use of CAM, physicians should routinely inquire about CAM use.

ABSTRACT

BACKGROUND: People with epilepsy (PWE) and people with intellectual disabilities (ID) both live shorter lives than the general population and both conditions increase the risk of death further. We aimed to measure associations between certain risk factors for death in PWE and ID. METHODS: A retrospective case-control study was conducted in ten regions in England and Wales. Data were collected on PWE registered with secondary care ID and neurology services between 2017 and 2021. Prevalence rates of neurodevelopmental, psychiatric and medical diagnoses, seizure frequency, psychotropic and antiseizure medications (ASM) prescribed, and health activity (epilepsy reviews/risk assessments/care plans/compliance etc.) recorded were compared between the two groups. RESULTS: 190 PWE and ID who died were compared with 910 living controls. People who died were less likely to have had an epilepsy risk assessment but had a greater prevalence of genetic conditions, older age, poor physical health, generalized tonic-clonic seizures, polypharmacy (not ASMs) and antipsychotic use. The multivariable logistic regression for risk of epilepsy-related death identified that age over 50, medical condition prevalence, antipsychotic medication use and the lack of an epilepsy review in the last 12 months as associated with increased risk of death. Reviews by psychiatrists in ID services was associated with a 72% reduction in the odds of death compared neurology services. CONCLUSIONS: Polypharmacy and use of antipsychotics may be associated with death but not ASMs. Greater and closer monitoring by creating capable health communities may reduce the risk of death. ID services maybe more likely to provide this holistic approach.

ABSTRACT

PURPOSE: Nearly a quarter of people with Intellectual disability (PwID) have epilepsy. Many have seizures across their lifetime. In the UK supporting their epilepsy linked risks and needs, particularly in professional care settings and in the community, requires significant social care input. Therefore, the interface between social and health care services is important. This study aim is to identify key intersectional areas of social provision for PWID and epilepsy. METHODS: A scoping review of the literature was performed in accordance with PRISMA guidance with suitable search terms. The search was completed in CINAHL, Embase, Psych INFO, SCIE, and Cochrane electronic databases by an information specialist. A quality assessment was completed for the included studies where appropriate. The included studies were analysed qualitatively to identify key themes and provide a narrative description of the evidence by two reviewers. RESULTS: Of 748 papers screened, 94 were retrieved. Thirteen articles met the inclusion criteria with a range of methodologies. A thematic analysis generated four key categories for significant social care involvement i.e., staff training and education; emergency seizure management; holistic approach to care; and nocturnal monitoring and supervision. CONCLUSIONS: PwID with epilepsy have support needs that require fulfilling by various aspects of special care provision, many within the social ambit. Inspite of evidence of these needs and recurrent calls to work jointly with social care providers this has not happened. There is limited research into social care role in epilepsy management in PwID which needs addressing.

ABSTRACT

OBJECTIVE: Argininosuccinate lyase (ASL) is integral to the urea cycle, which enables nitrogen wasting and biosynthesis of arginine, a precursor of nitric oxide. Inherited ASL deficiency causes argininosuccinic aciduria, the second most common urea cycle defect and an inherited model of systemic nitric oxide deficiency. Patients present with developmental delay, epilepsy, and movement disorder. Here we aim to characterize epilepsy, a common and neurodebilitating comorbidity in argininosuccinic aciduria. METHODS: We conducted a retrospective study in seven tertiary metabolic centers in the UK, Italy, and Canada from 2020 to 2022, to assess the phenotype of epilepsy in argininosuccinic aciduria and correlate it with clinical, biochemical, radiological, and electroencephalographic data. RESULTS: Thirty-seven patients, 1-31 years of age, were included. Twenty-two patients (60%) presented with epilepsy. The median age at epilepsy onset was 24 months. Generalized tonic-clonic and focal seizures were most common in early-onset patients, whereas atypical absences were predominant in late-onset patients. Seventeen patients (77%) required antiseizure medications and six (27%) had pharmacoresistant epilepsy. Patients with epilepsy presented with a severe neurodebilitating disease with higher rates of speech delay (p = .04) and autism spectrum disorders (p = .01) and more frequent arginine supplementation (p = .01) compared to patients without epilepsy. Neonatal seizures were not associated with a higher risk of developing epilepsy. Biomarkers of ureagenesis did not differ between epileptic and non-epileptic patients. Epilepsy onset in early infancy (p = .05) and electroencephalographic background asymmetry (p = .0007) were significant predictors of partially controlled or refractory epilepsy. SIGNIFICANCE: Epilepsy in argininosuccinic aciduria is frequent, polymorphic, and associated with more frequent neurodevelopmental comorbidities. We identified prognostic factors for pharmacoresistance in epilepsy. This study does not support defective ureagenesis as prominent in the pathophysiology of epilepsy but suggests a role of central dopamine deficiency. A role of arginine in epileptogenesis was not supported and warrants further studies to assess the potential arginine neurotoxicity in argininosuccinic aciduria.

ABSTRACT

Importance: Women with epilepsy are recommended high doses of folic acid before and during pregnancy owing to risk of congenital anomalies associated with antiseizure medications. Whether prenatal exposure to high-dose folic acid is associated with increases in the risk of childhood cancer is unknown. Objective: To assess whether high-dose folic acid supplementation in mothers with epilepsy is associated with childhood cancer. Design, Setting, and Participants: Observational cohort study conducted with nationwide registers in Denmark, Norway, and Sweden from 1997 to 2017. Analyses were performed during January 10, 2022, to January 31, 2022. Mother-child pairs were identified in medical birth registers and linked with information from patient, prescription, and cancer registers, as well as with sociodemographic information from statistical agencies, and were categorized by maternal diagnosis of epilepsy. The study population consisted of 3 379 171 children after exclusion of 126 711 children because of stillbirth or missing or erroneous values on important covariates. Exposures: Maternal prescription fills for high-dose folic acid tablets (≥1 mg daily) between 90 days before pregnancy start and birth. Main Outcomes and Measures: First onset of childhood cancer at younger than 20 years. Cox proportional hazards models were used to calculate adjusted hazard ratios with corresponding 95% CIs, adjusted for potential confounders. Cumulative incidence at aged 20 years was used as a measure of absolute risk. Results: The median age at the end of follow-up in the study population of 3 379 171 children was 7.3 years (IQR, 3.5-10.9 years). Among the 27 784 children (51.4% male) born to mothers with epilepsy, 5934 (21.4%) were exposed to high-dose folic acid (mean dose, 4.3 mg), with 18 exposed cancer cases compared with 29 unexposed, producing an adjusted hazard ratio of 2.7 (95% CI, 1.2-6.3), absolute risk if exposed of 1.4% (95% CI, 0.5%-3.6%), and absolute risk if unexposed of 0.6% (95% CI, 0.3%-1.1%). In children of mothers without epilepsy, 46 646 (1.4%) were exposed to high-dose folic acid (mean dose, 2.9 mg), with 69 exposed and 4927 unexposed cancer cases and an adjusted hazard ratio of 1.1 (95% CI, 0.9-1.4; absolute risk, 0.4% [95% CI, 0.3%-0.5%]). There was no association between children born to mothers with epilepsy who were prenatally exposed to antiseizure medications, but not high-dose folic acid, and an increased risk of cancer (absolute risk, 0.6%; 95% CI, 0.2%-1.3%). Conclusions and Relevance: Prenatal exposure to high-dose folic acid was associated with increased risk of cancer in children of mothers with epilepsy.

ABSTRACT

BACKGROUND: Vitamin D deficiency has been linked to various medical conditions such as bone loss, decreased mineralization, endocrine disorders, and central nervous system disorders, including epilepsy. Vitamin D deficiency is prevalent among patients with epilepsy (PWE). However, the specific association between vitamin D levels and age in PWE is unclear. OBJECTIVES: Identify the relation between vitamin D level and age in PWE and evaluate factors that may play a role in seizure control. DESIGN: Retrospective analytical medical record review SETTING: Outpatient epilepsy research clinic in Saudi Arabia PATIENTS AND METHODS: Between November 2016 and April 2020, we selected eligible PWE aged older than 14 years whose vita-min D levels were recorded at least once after reviewing 1550 patient electronic files. We analyzed data on serum vitamin D level by age and other factors, vitamin D supplement use, seizure classification, and conducted a multivariate logistic regression to assess associations with seizure control. MAIN OUTCOME MEASURES: Relationships between vitamin D levels and age and factors that might affect seizure control. SAMPLE SIZE: 524 patients RESULTS: The prevalence of low serum vitamin D levels was high (86.8%). The median vitamin D level in all patients was low (38 nmol/L), and was lower in young PWE than in adult PWE (P<.01). Only 146 patients received vitamin D supplements. High vitamin D levels were associated with a 40% seizure reduction. CONCLUSION: Vitamin D deficiency is underestimated in PWE in Saudi Arabia, and is more prevalent among young adults and patients on polytherapy than in other PWE. Patients with high vitamin D levels had good seizure control compared with those with low levels. The effect of vitamin D supplements on seizure control should be further investigated in randomized control trials. LIMITATIONS: Retrospective study and no categorization by presence of supplementation. CONFLICT OF INTEREST: None.

ABSTRACT

OBJECTIVE: Tuberous sclerosis complex (TSC) is a rare multisystem disorder, often associated with epilepsy. This retrospective study aimed to identify patients with TSC, including those with epilepsy, from a French healthcare claims database, and to report incidence, prevalence, and healthcare costs and resource utilization. METHODS: The anonymized French health insurance database (SNDS) covers almost the entire French population. Patients with TSC were identified as having ≥1 International Classification of Diseases, Tenth Revision (ICD-10) diagnosis code Q85.1 or a long-term disease (LTD) registration over the inclusion period (2006-2017). Patients with an ICD-10 epilepsy code or who were dispensed ≥1 antiseizure medication (ASM) in the same year or after their TSC diagnosis were identified as having TSC with epilepsy. Newly diagnosed patients over the inclusion period constituted the incident cohort. Healthcare costs (patients with recorded costs only), healthcare resource use, and ASM dispensation are reported for patients with 2018 data. RESULTS: In 2018, 3139 prevalent patients with TSC were identified (crude prevalence, 4.69 per 100 000); the incident cohort comprised 2988 patients (crude incidence, 0.44 per 100 000). Among patients with TSC, 67% (2101/3139) had epilepsy (mean [standard deviation, SD] age: 28.8 [18.8] years; male: 48%). Among patients with epilepsy, total mean (SD) annual healthcare costs were €11 413 (27 620) per capita (outpatient, 63%; inpatient, 37%), 46% were hospitalized during 2018 (mean [SD]: 1.8 [10.9] acute care visits per patient), and 65% visited a hospital specialist. Among patients with epilepsy, medication (mean [SD]: €4518 [12 102] per capita) was the greatest contributor (63%) to outpatient costs, and in 2018, 74% were dispensed ≥1 different ASM and 9% were dispensed ≥4 ASMs. SIGNIFICANCE: TSC with epilepsy was associated with substantial healthcare costs and resource utilization, particularly outpatient and medication costs. Many patients with TSC with epilepsy were prescribed multiple ASMs, suggesting refractory epilepsy.

ABSTRACT

BACKGROUND AND OBJECTIVES: Women with epilepsy treated with antiseizure medication (ASM) have increased risk of pregnancy complications including preterm birth, fetal growth restriction, and preeclampsia. We aimed to investigate whether folic acid supplementation is associated with these pregnancy complications in women with epilepsy using ASM. METHODS: Singleton pregnancies in the prospective Norwegian Mother and Child Cohort Study (MoBa) (1999-2008) were included. Information on maternal epilepsy, ASM, folic acid supplementation, and pregnancy outcomes was obtained from the MoBa questionnaires and the Norwegian Medical Birth Registry. The main exposure, periconceptional folic acid supplementation, was defined as intake between 4 weeks before pregnancy and 12 weeks into pregnancy, retrospectively collected by recall of the mothers in weeks 17-19. The primary outcomes were preterm birth (gestational age <37 weeks at birth), small for gestational age (SGA), and preeclampsia. RESULTS: The study included 100,105 pregnancies: 99,431 without maternal epilepsy, 316 with maternal epilepsy and ASM exposure in pregnancy, and 358 with untreated maternal epilepsy. Among ASM-treated women with epilepsy, the risk of preterm birth was higher in those who did not use periconceptional folic acid (n = 64) compared with those who did (n = 245, the reference) (adjusted odds ratio [aOR] 3.3, 95% CI 1.2-9.2), while the risk of preterm birth among the reference was similar to the risk among women without epilepsy using folic acid periconceptionally (aOR 0.9, 95% CI 0.5-1.6). ASM-treated women with epilepsy starting folic acid after the first trimester had a higher risk compared with women without epilepsy with similar timing of folic acid (aOR 2.6, 95% CI 1.1-6.5), and even higher if not using folic acid (aOR 9.4, 95% CI 2.6-34.8). Folic acid was not associated with risk of preterm birth among women with epilepsy without ASM or among women without epilepsy. Folic acid was not associated with risk of preeclampsia or SGA among women with epilepsy. DISCUSSION: In women with epilepsy using ASM, periconceptional folic acid was associated with a lower risk of preterm birth. This finding supports the recommendation that ASM-treated women with epilepsy of childbearing potential should use folic acid supplementation on a regular basis. CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that for women with epilepsy using ASM, periconceptional folic acid supplementation decreases the risk of preterm birth.

ABSTRACT

BACKGROUND: This study examines mental, neurological, and substance use (MNS) service usage within refugee camp primary health care facilities in low- and middle-income countries (LMICs) by analyzing surveillance data from the United Nations High Commissioner for Refugees Health Information System (HIS). Such information is crucial for efforts to strengthen MNS services in primary health care settings for refugees in LMICs. METHODS: Data on 744,036 MNS visits were collected from 175 refugee camps across 24 countries between 2009 and 2018. The HIS documented primary health care visits for seven MNS categories: epilepsy/seizures, alcohol/substance use disorders, mental retardation/intellectual disability, psychotic disorders, severe emotional disorders, medically unexplained somatic complaints, and other psychological complaints. Combined data were stratified by 2-year period, country, sex, and age group. These data were then integrated with camp population data to generate MNS service utilization rates, calculated as MNS visits per 1000 persons per month. RESULTS: MNS service utilization rates remained broadly consistent throughout the 10-year period, with rates across all camps hovering around 2-3 visits per 1000 persons per month. The largest proportion of MNS visits were attributable to epilepsy/seizures (44.4%) and psychotic disorders (21.8%). There were wide variations in MNS service utilization rates and few consistent patterns over time at the country level. Across the 10 years, females had higher MNS service utilization rates than males, and rates were lower among children under five compared to those five and older. CONCLUSIONS: Despite increased efforts to integrate MNS services into refugee primary health care settings over the past 10 years, there does not appear to be an increase in overall service utilization rates for MNS disorders within these settings. Healthcare service utilization rates are particularly low for common mental disorders such as depression, anxiety, post-traumatic stress disorder, and substance use. This may be related to different health-seeking behaviors for these disorders and because psychological services are often offered outside of formal health settings and consequently do not report to the HIS. Sustained and equitable investment to improve identification and holistic management of MNS disorders in refugee settings should remain a priority.

ABSTRACT

Alcohol, coffee and milk intakes have been explored in relation to epilepsy risk in observational studies; however, the results were not consistent. We performed a Mendelian randomisation (MR) study to evaluate the causality of these relationships. Genetic variants associated with alcohol, coffee and milk intake were adopted as instrumental variables. We obtained the summary data of epilepsy from the International League Against Epilepsy (ILAE) Consortium (15,212 cases and 29,677 controls) and FinnGen consortium (4588 cases and 144,780 controls). Genetically predicted alcohol intake was associated with a higher risk of epilepsy in the ILAE Consortium (odds ratio (OR): 1.22, 95% confidence intervals (CI): 1.02-1.45). The association in the FinnGen consortium remained consistent in direction. Combined analysis of ILAE and FinnGen databases further indicated that genetically predicted alcohol intake was associated with a higher risk of epilepsy (OR = 1.24; 95% CI, 1.06-1.47, p = 0.009). Genetically predicted coffee intake was not related to epilepsy risk, while higher genetically predicted milk intake was related to a lower risk of epilepsy (OR = 0.957; 95% CI, 0.917-0.999, p = 0.044). Our results suggest a detrimental effect of alcohol intake on the risk of epilepsy, while milk intake might be associated with a decreased risk of epilepsy.

ABSTRACT

PURPOSE OF THE RESEARCH: The geriatric population is the fastest-growing population in the United States and the impact of incident epilepsy on the cognitively intact geriatric population is not well-studied. Understanding how epilepsy affects the elderly is important to improve the quality of treatment and care for our aging population. This study sought to address the impact of incident epilepsy on the perceived Quality of Life (QOL) in cognitively intact elderly using the SF-36 questionnaire. METHODS: Nine hundred and twenty-seven participants were assessed from a community-based cohort. Based on a history of subsequent development of new-onset seizures, participants were divided into two groups, an incident seizure group that developed new-onset seizures after 65 years of age and the control group without incident seizures. Of this, six hundred eleven were analyzed with the SF-36 questionnaire after excluding for cognitive decline and inconsistent medical data. PRINCIPAL RESULTS: Statistically significant differences were found in 9 items on SF-36, involving perception of increased physical disability (p < 0.01; t-test), frailty (p < 0.04; t-test), emotional health limitations (p < 0.03; t-test), anxiety and sadness (p < 0.04; t-test), problems interfering with social activities (p < 0.0001; t-test). No between-group differences were found for demographic variables including age, education, gender, or minority status. Among the 611 subjects who remained cognitively normal across all longitudinal visits, 12 reported a history of new-onset seizures. Ten of these 12 subjects were seizure free as a result of treatment, with only 2 experiencing recent seizures. The incidence of seizures in our population was 300 per 100,000 person years. MAJOR CONCLUSIONS: This study identified the elderly population with incident epilepsy as a subgroup with an unmet health need, and healthcare professionals should address the potential impact of seizures with their geriatric patients to ensure comprehensive care.

ABSTRACT

BACKGROUND: Anti-seizure medication (ASM) treatment is one of the significant risk factors associated with abnormal vitamin D status in epilepsy patients. Multiple studies have shown that adult epilepsy patients can exhibit vitamin D deficiency. However, there are few reports investigating pediatric epilepsy patients. In this study, we aimed to identify risk factors related to hypovitaminosis D in pediatric epilepsy patients in Thailand. METHODS: A cross-sectional retrospective cohort study was conducted in 138 pediatric epilepsy patients who received anticonvulsants from April 2018 to January 2019. Demographic data, seizure types, puberty status, physical activity, duration, and types of anti-seizure medications were analyzed. Patients with abnormal liver function, abnormal renal function, and who received vitamin D supplements or ketogenic diet containing vitamin D were excluded. Levels of serum vitamin D (25(OH)D) were measured. RESULTS: All 138 subjects were enrolled, the age ranged from 1.04 - 19.96 years; (mean = 9.65 ± 5.09), the mean serum 25(OH) D level was 26.56 ± 9.67 ng/ml. The prevalence of vitamin D deficiency was 23.2% and insufficiency was 47.8% respectively. Two risk factors-puberty status (OR 5.43, 95% CI 1.879-15.67) and non-enzyme-inhibiting ASMs therapy (OR 3.58, 95% CI 1.117-11.46)-were significantly associated with hypovitaminosis D, as shown by multivariate analyses. CONCLUSIONS: Our study reports the high prevalence of hypovitaminosis D in pediatric epilepsy patients in Thailand despite being located in the tropical zone. These findings can guide clinicians to measure vitamin D status in pediatric epilepsy patients particularly when they reach puberty and/or are using non-enzyme-inhibiting ASMs therapy. Early detection of vitamin D status and prompt vitamin D supplementation can prevent fractures and osteoporosis later in life.

ABSTRACT

BACKGROUND: Long-term use of antiseizure drugs is associated with a low bone mineral density (BMD) and an increased fracture risk. The literature regarding institutionalised children on chronic antiseizure drugs is limited. Therefore, the aim of this cross-sectional study is to evaluate the prevalence of low BMD and the history of fractures in institutionalised children with epilepsy and intellectual disability (ID). METHODS: A dual-energy X-ray absorptiometry of lumbar spine (L1-L4) and hip was performed in 24 children, residing in a long-stay care facility in the Netherlands. Additionally, serum concentrations of albumin, calcium and 25-hydroxyvitamin D were determined. Data on fractures were retrospectively extracted from the medical files. RESULTS: Ages of the children (14 male and 10 female) ranged from 5 to 17 years with a mean age of 13.0 (±3.2). The criteria of the International Society for Clinical Densitometry (ISCD) were used for classification of bone mineral disorders. Eight (33.3%) children had a normal BMD (Z-score > - 2.0). Of the 16 children with a low BMD (Z-score ≤ - 2.0), three were diagnosed as osteoporotic, based on their fracture history. Ten children (41.7%) were reported to have at least one fracture in their medical history. Serum concentrations of albumin-corrected calcium (2.28-2.50 mmol/L) and (supplemented) vitamin D (16-137 nmol/L) were within the normal range. CONCLUSIONS: This study demonstrated that 67% of institutionalised children with epilepsy and ID had low BMD and 42% had a history of at least one fracture, despite supplementation of calcium and vitamin D in accordance with the Dutch guidelines.
