Chia ZJ, Jehosua SY, Lim KS, Khosama H, Hamid DH, Fong SL, et al.

PMID: 31839499 DOI: 10.1016/j.yebeh.2019.106833

INTRODUCTION: Epilepsy stigma has been associated with poor quality of life among people with epilepsy (PWE). It is important to understand the variation and degree of epilepsy stigma in one of the most populous and culturally diverse nations in the world, Indonesia. Hence, this study aimed to test the validity and reliability of the Indonesian version of the Public Attitudes Toward Epilepsy (PATE) scale.
METHOD: The translation was performed according to standard principles and tested in 200 native Indonesian speakers who were aged above 18-year-old for psychometric validation.
RESULTS: The items in each domain had similar means and standard deviations (equal item variance), means ranging from 2.17 to 2.86 in general domain and 2.75 to 3.56 in personal domain and, standard deviations ranging from 0.87 to 1.05 and 0.88 to 1.01 in general and personal domain, respectively. Item-domain correlations were more than 0.5 for all items, and they correlate higher within their own domain compare with the other domain (convergent and divergent validity). Multitrait analysis showed similar variance, floor, and ceiling patterns to a great extent compared with the initial study. The Indonesian PATE scale also showed mostly similar correlation with demographic characteristics except monthly income. Principle axis analysis revealed strong factor loading (>0.3) in their hypothesized domain, except item 14. The Cronbach's α values for general and personal domains were 0.836 and 0.765, which were within the accepted range of 0.7 to 0.9.
CONCLUSION: The Indonesian PATE scale is a validated and reliable translation for measuring public attitudes toward epilepsy.

Status epilepticus (SE) is a life-threatening neurological condition with significant mortality. Rapid management is essential to minimize the mortality and disability of SE. Two recent trials provided evidence to guide SE management in early and established stages. The Rapid Anticonvulsant Medication Prior To Arrival Trial (RAMPART, 2011) showed that intramuscular midazolam is a better alternative for early convulsive SE in prehospital settings. The Established Status Epilepticus Treatment Trial (ESETT, 2020) supported the use of sodium valproate and levetiracetam as second-line treatment for its efficacy and shorter administration time. However, there are challenges to revising the status epilepticus management in resource-limited settings, in pre-hospital, first- and second-line treatment, as well as management of refractory and super-refractory SE. These challenges included restrictions or lack of training in the administration of benzodiazepine in the prehospital setting, limited availability and accessibility of newer antiseizure medications (ASMs) in emergency departments and smaller hospitals, and low clinicians' awareness of the latest evidence. A collaborative effort to educate, improve awareness, and make certain ASMs more readily available is recommended to achieve a better clinical outcome in SE.
Cost-effectiveness analysis of HLA-B*15:02 screening before treatment of epilepsy in Indonesia

INTRODUCTION: Adverse skin reactions due to drugs such as Stevens Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) occur in 3% of people receiving anti epileptic drugs (AED). Although SJS/TEN has a low incidence, the mortality and morbidity rates are high. Indonesia has not adopted HLA-B*1502 screening prior to administration of carbamazepine (CBZ), although previous studies found a relationship between HLA-B*1502 and SJS/TEN.
METHODS: A hybrid decision tree and Markov model was developed to evaluate three strategies for treating newly diagnosed focal epilepsy: CBZ direct therapy, levetiracetam (LEV) direct therapy, and therapy based on HLA-B*15:02 test results. From a societal perspective, base case and sensitivity analyses were carried out over a lifetime.
RESULTS: Direct administration of CBZ appears to have a slightly lower average cost than the HLA-B*15:02 allele screening strategy. The increase in quality-adjusted life year (QALY) in HLA-B*15:02 screening before treatment related to the cost difference reached 0.519 with an incremental cost-effectiveness ratio (ICER) of around USD 984 per unit of QALY acquisition. Direct treatment of LEV increased treatment costs by almost USD 2000 on average compared to the standard CBZ strategy. The increase in QALY is 0.834 in direct levetiracetam treatment, with an ICER of around USD 2230 for each QALY processing.
CONCLUSION: Calculation of the cost-effectiveness of lifetime epilepsy therapy in this study found that the initial screening strategy with the HLA-B*15:02 test was the most cost-effective.
Affordability of newer antiseizure medications in Asian resource-limited countries

OBJECTIVE: One of the objectives of the Intersectoral Global Action Plan on epilepsy and other neurological disorders for 2022 to 2031 is to ensure at least 80% of people with epilepsy (PWE) will have access to appropriate, affordable, and safe antiseizure medications (ASMs) by 2031. However, ASM affordability is a significant issue in low- and middle-income countries, preventing PWE from accessing optimal treatment. This study aimed to determine the affordability of the newer (second and third generation) ASMs in resource-limited countries in Asia.
METHODS: We conducted a cross-sectional survey by contacting country representatives in lower-middle-income countries (LMICs) in Asia, including Indonesia, Lao People's Democratic Republic (PDR), Myanmar, Philippines, Vietnam, India, Bangladesh, and Pakistan, and the upper-middle-income country Malaysia, from March 2022 to April 2022. The affordability of each ASM was calculated by dividing the 30-day ASM cost by the daily wage of the lowest paid unskilled laborers. Treatment costing 1 day's wage or less for a 30-day supply of chronic disease is considered affordable.
RESULTS: Eight LMICs and one upper-middle-income country were included in this study. Lao PDR had no newer ASM, and Vietnam had only three newer ASMs. The most frequently available ASMs were levetiracetam, topiramate, and lamotrigine, and the least frequently available was lacosamide. The majority of the newer ASMs were unaffordable, with the median number of days' wages for a 30-day supply ranging from 5.6 to 14.8 days.
SIGNIFICANCE: All new generation ASMs, whether original or generic brands, were unaffordable in most Asian LMICs.
