A quality of care assessment for women of childbearing potential with epilepsy in Bhutan: An observational study.

BACKGROUND & OBJECTIVE: In lower-middle income countries such as Bhutan, the treatment gap for epilepsy is over 50% as compared to a treatment gap of less than 10% in high-income countries. We aim to analyze the quality of epilepsy care for women of childbearing potential in Bhutan using the Quality Indicators in Epilepsy Treatment (QUIET) tool, and to assess the usefulness of the tool's section for women with active epilepsy (WWE) in the Bhutanese setting. METHODS: A prospective convenience cohort was enrolled in Thimphu, Paro, Punakha, and Wangdue, Kingdom of Bhutan, in 2022. Bhutanese women of childbearing potential at the time of enrollment (18-44 years old) were evaluated for the diagnosis of active epilepsy and underwent a structured survey-based interview with Bhutanese staff. Participants were surveyed on their epilepsy, pregnancy, and antiseizure medicine (ASM) histories. The clinical history and quality of epilepsy care of adult WWE were assessed using a section of the QUIET tool for women, an instrument originally developed by the U.S. Department of Veterans Affairs to analyze the quality of epilepsy care for American adults. RESULTS: There were 82 Bhutanese WWE of childbearing potential, with mean age of 30.6 years at enrollment (range 18-44, standard deviation (SD) 6.6) and mean age of 20.3 years at epilepsy diagnosis (range 3-40, SD 8.0)). 39 % (n = 32) had a high school or above level of education, and 42 % (n = 34) were employed. 35 % (n = 29) reported a seizure within the prior week, and 88 % (n = 72) reported a seizure within the prior year. 49 % (n = 40) of participants experienced > 100 lifetime seizures. All but one participant took antiseizure medications (ASMs). At enrollment, participants presently took no (n = 1), one (n = 3), two (n = 37), three (n = 25), four (n = 11), or over five (n = 5) ASMs. The most common ASMs taken were levetiracetam (n = 40), phenytoin (n = 27), carbamazepine (n = 23), phenobarbital (n = 22), and sodium valproate (n = 20). 61 % of all WWE took folic acid. Of the 40 previously pregnant WWE, eight (20 %) took folic acid during any time of their pregnancy. 35 % (n = 29) used betel nut (doma, quid) and 53 % (n = 21) of pregnant WWE used betel nut during pregnancy. CONCLUSIONS: Based on data about WWE participants' ASM, supplement, and substance use, our study identified the high use of first generation ASMs (including valproate), frequently in polytherapy, and betel nut use as treatment gaps in women of childbearing potential age with active epilepsy in Bhutan. To address these gaps for locations such as Bhutan, we propose modifications to the QUIET tool's "Chronic Epilepsy Care for Women" section.

Depression, sleep quality, and social isolation among people with epilepsy in Bhutan: A cross-sectional study.

PURPOSE: The aim of this study was to analyze the possible contributions of seizure burden, sleep quality, and social integration to depression among people with epilepsy (PWE) in Bhutan. METHODS: Bhutan is a lower-middle-income country in Southeast Asia with a public healthcare system without neurologists. People with epilepsy were prospectively recruited from psychiatrist-run epilepsy clinics at the National Referral Hospital in the capital city of Thimphu. Adult participants with epilepsy were interviewed for clinical history, sleep quality using the Pittsburgh Sleep Quality Index, social networks using the Berkman-Syme Social Network Index, and depressive symptoms using the Patient Health Questionnaire - 9 (PHQ-9). A multivariable regression model was built to assess the relationship between depression as an outcome and the possible contributors of sleep quality, sex, and seizure in the prior month. RESULTS: Out of 80 participants (39 women, mean age: 29.4 years old, range: 18-56 years, 58 [73%] with a seizure in the previous month), 33% had poor sleep quality, 68% were socially isolated, 30% had a mild depressive symptom burden or more, and 18% reported suicidal ideation at the time of their interview. Women had a higher average PHQ-9 score versus men, which showed a trend towards statistical significance (5.6 versus 3.3 PHQ-9 points, p = 0.07), and on average met criteria for mild depression. Social integration was not significantly associated with sleep quality and had no relationship with depressive burden. There was a small positive correlation between poorer sleep quality and depressive symptoms which showed a trend towards statistical significance (r = 0.21, p = 0.06). In a multivariable regression, poor sleep quality was associated with higher depressive symptom burden, adjusting for participant sex and having a seizure in the previous month (p = 0.01). CONCLUSIONS: Our exploratory study disentangles the multilayered psychosocial burden of disease experienced by PWE in Bhutan, a lower-middle-income country with access to antiseizure medications and psychiatrists but not expert epilepsy services or human resources. Further investigation into the interrelationships among social isolation, poor sleep quality, depression, and seizure burden could identify preventable and remediable constituents of this burden.

The economic burden of epilepsy in Bhutan.

OBJECTIVE: To assess the economic impact of epilepsy in Bhutan, a lower-middle-income country with a universal health care system, but with limited access to neurological care. METHODS: A cross-sectional survey was conducted of patients with epilepsy at the Jigme Dorji Wangchuk National Referral Hospital from January to August 2016. Data were collected on clinical features, cost of care, impact of epilepsy on school or work and household economic status of participants and matched comparisons (a sibling or neighbour from a household without epilepsy). RESULTS: A total of 172 individuals were included in the study (130 adults and 42 children). One-third of adults and 20 (48%) children had seizures at least once per month. Mean direct out-of-pocket cost for epilepsy care was 6054 Bhutanese Ngultrum (BTN; 91 USD) per year, of which transportation formed the greatest portion (53%). Direct costs of epilepsy were an average of 3.2% of annual household income. Adults missed 6.8 (standard deviation [SD]: 9.0) days of work or school per year on average, and children missed 18.6 (SD: 34.7) days of school. Among adults, 23 (18%) abandoned employment or school because of epilepsy; seven children (18%) stopped school because of epilepsy. Households with a person with epilepsy had a lower monthly per-person income (6434 BTN) than comparison households without epilepsy (8892 BTN; P = 0.027). CONCLUSIONS: In Bhutan, despite universal health care services, households of people with epilepsy face a significant economic burden. With many adults and children unable to attend school or work, epilepsy causes a major disruption to individuals' livelihoods.

Yield of Brain MRI in Clinically Diagnosed Epilepsy in the Kingdom of Bhutan: A Prospective Study.

BACKGROUND: People with epilepsy (PWE) in low- and middle-income countries may not access the health resources that are considered optimal for epilepsy diagnosis. The diagnostic yield of magnetic resonance imaging (MRI) has not been well studied in these settings. OBJECTIVES: To report the diagnostic yield of brain MRI and identify clinical associations of abnormal MRI findings among PWE in a neurocysticercosis-endemic, resource-limited setting and to identify the proportion and putative structural brain causes of drug-resistant epilepsy. METHODS: PWE were prospectively enrolled at the Jigme Dorji Wangchuck National Referral Hospital in Bhutan (2014-2015). Each participant completed clinical questionnaires and a 1.5-Tesla brain MRI. Each MRI was reviewed by at least 1 radiologist and neurologist in Bhutan and the United States. A working definition of drug-resistant epilepsy for resource-limited settings was given as (a) seizures for >1 year, (b) at least 1 seizure in the prior year, and (c) presently taking 2 or more antiepileptic drugs (AEDs). Logistic regression models were constructed to test the cross-sectional association of an abnormal brain MRI with clinical variables. FINDINGS: A total of 217 participants (125 [57%] female; 54 [25%] < 18 years old; 199 [92%] taking AEDs; 154 [71%] with a seizure in the prior year) were enrolled. There was a high prevalence of abnormal brain MRIs (176/217, 81%). Mesial temporal sclerosis was the most common finding (n = 115, 53%, including 24 children), exceeding the number of PWE with neurocysticercosis (n = 26, 12%, including 1 child) and congenital/perinatal abnormalities (n = 29, 14%, including 14 children). The number of AEDs (odds ratio = .59, P = .03) and duration of epilepsy (odds ratio = 1.11, P = .02) were significantly associated with an abnormal MRI. Seizure in the prior month was associated with the presence of mesial temporal sclerosis (odds ratio = .47, P = .01). A total of 25 (12%) participants met our definition of drug-resistant epilepsy, with mesial temporal sclerosis (n = 10), congenital malformations (n = 5), and neurocysticercosis (n = 4) being the more common findings. CONCLUSIONS: The prevalence of abnormalities on brain MRI for PWE in resource-limited settings is high as a result of a diffuse range of etiologies, most commonly mesial temporal sclerosis. Drug-resistant epilepsy accounted for 12% of the referral population in a conservative estimation.

Contraception, pregnancy, and peripartum experiences among women with epilepsy in Bhutan.

INTRODUCTION: Reports on the reproductive health of women with epilepsy (WWE) in low- and middle-income countries (LMICs) are limited. Bhutan is a lower income country with a high estimated prevalence of epilepsy and no out-of-pocket payment requirements for health visits or medications. METHODS: We developed a 10-category survey to interview WWE ages 20-59 years in the Kingdom of Bhutan to understand their contraceptive use and peripartum experiences. WWE were recruited from 2016-2017 from an existing epilepsy cohort and their reproductive health data were merged with epilepsy and socioeconomic data obtained from initial clinical evaluations performed between 2014 and 2016. RESULTS: Of the 134 WWE eligible for the study, 94 were reachable and there was 1 refusal to participate (response rate 99% among reachable WWE; 69% of all WWE in the cohort). Of the 93 WWE (median age 27 years, range 20-52), 50 (54%) reported prior pregnancies. Of the entire cohort, 55 women responded on contraception: 26 (47%) WWE had never used contraception in their lifetime. Of the 29 WWE who had ever used contraception, the most commonly reported form was male condoms (14/29, 48%), followed by depot medroxyprogesterone acetate injections (13/29, 45%), and intrauterine devices (5/29, 17%). Sixty-three percent of WWE recalled receiving information on family planning (31 of 49). Of the 50 WWE with prior pregnancies, 37 of 46 (80%) used folic acid; 6 WWE reported commencing it in the first trimester while 29 WWE began supplementation in the second trimester. Primary school education or higher was associated with folic acid supplementation during pregnancy (26/29 vs. 11/17, p=0.040). Epilepsy affected at least one of the pregnancies in 38 of the cases (76%) with an average of 2.3 pregnancies per woman). There was a total of 86 pregnancies and an average inter-pregnancy interval of 3.5 years. Ninety-five percent of women attended prenatal care (36/38), 22% had at least one miscarriage (8/37), 14% had at least one pre-term delivery (5/36), and 21% had Caesarean sections (8/38). Seventeen of 38 (45%) of WWE had seizures during pregnancy. A majority of WWE (97%, 37 of 38) with a prior pregnancy reported breastfeeding their infant. CONCLUSIONS: Nearly half of Bhutanese WWE did not use contraception; among those who used it, male condoms were most common but 11% were at risk of potential drug-drug interactions between oral contraception and enzyme-inducing antiepileptic drugs. Bhutanese WWE had a high rate of prenatal visits. Folic acid was prescribed in most pregnant WWE but the majority began supplementation in the second trimester. The number of pregnancies in WWE in Bhutan (2.3 per woman) was comparable to the number of children per women in Bhutan (2.3). Breastfeeding was practiced almost universally. Points of intervention may include pre-conception initiation of folic acid, optimization of dosing of AEDs with contraceptives, guidelines for peripartum seizure treatment, and establishment of a prospective registry for WWE and their offspring.

Areca catechu (palm tree) nut chewing and seizures: An observational study.

OBJECTIVE: The objective of this study was to report the impact of chronic abuse of Areca catechu nut wrapped in leaf (also known as doma, quid, paan), the fourth most commonly abused psychoactive substance worldwide, on the frequency of seizures among people with epilepsy. METHODS: People with clinically diagnosed epilepsy (>14years old) residing in the Kingdom of Bhutan were surveyed for self-reported Areca catechu use, demographic variables, epilepsy characteristics, and seizure frequency. The relationship between seizure frequency in the prior month and chewing Areca catechu, adjusted for various confounders, was analyzed using multivariable regression models. RESULTS: There were 152 people with epilepsy, including 50 chewers (33%) and 102 (67%) nonchewers. The median duration of chewing A. catechu was 62months (25th, 75th percentiles: 24, 120months). Chewers consumed an average of three nuts daily. There was no significant difference between chewers and nonchewers in the mean age, proportion of male vs. female, age at first epileptic seizure, or number of antiepileptic drugs presently taken; chewers were more likely to be rural dwellers (p=0.042). After adjustment for all of the above variables, on average, chewers had 58.7% fewer [95%CI: (-79.4, -17.0)] seizures in the prior month, equating to 2.1 fewer [95% CI: (-3.9, -0.3)] seizures. CONCLUSIONS: Our observational study suggests that the social custom of chewing Areca catechu nut is associated with reduced seizure frequency among people with epilepsy. This association may be due to its natural stimulant properties, a novel antiepileptic property of the nut, or has another, yet unknown explanation.
