Clinical management and disease-modifying treatment for amyotrophic lateral sclerosis in African hospital centers: the TROPALS study.

Objective: To assess the availability of health workers and medications for clinical management of amyotrophic lateral sclerosis (ALS) in African hospital centers. Availability and affordability analyses of disease-modifying treatments were performed. Methods: A multicenter observational study involving African hospitals was conducted. A standard questionnaire was developed based on the European Federation of the Neurological Societies (EFNS) guidelines. We collected data on multidisciplinary care and availability of medicines. The availability and affordability were evaluated according to the WHO guidelines. Results: Nine hospital centers from eight African countries participated. We observed a low degree of implementation of multidisciplinary care in ALS management. Riluzole was only available in centers from South Africa, Senegal, Tunisia, and Togo. This treatment was unaffordable and the adjusted price was highly variable among countries. The cost of riluzole was partly or fully covered by patients, which implies a substantial economic burden. Conclusion: Our findings strengthen the need to promote multidisciplinary care in the clinical management of ALS in Africa. Disease-modifying medication should be both available and affordable. Local and international collaboration is needed to improve ALS health care access in Africa.

Availability, affordability, and quality of essential anti-seizure medication in Cambodia.

OBJECTIVE: Epilepsy is a major neurological disorder that requires long-term medical treatment. Once epilepsy is diagnosed, people with epilepsy face many difficulties in accessing treatment (treatment gap). Our objective was to assess the situation regarding the availability, price, affordability, and quality of anti-seizure medication (ASM), which are major determinants of access to treatment. METHOD: A cross-sectional study was performed in provincial/district hospitals and private pharmacies in urban and rural areas in Cambodia. Data on ASM availability and price were obtained through drug suppliers. Affordability was estimated as the number of day wages the lowest-paid government employee must work to purchase a monthly treatment. Samples of ASM were collected, and the quality of ASM was assessed through Medicine Quality Assessment Reporting Guidelines. RESULTS: Out of 138 outlets visited, only 72 outlets (52.2% [95% CI 43.5-60.7]) had at least one ASM available. Phenobarbital 100 mg was the most available (35.5%), followed by carbamazepine 200 mg (21.7%), phenobarbital 50 mg (11.6%), sodium valproate 500 mg (9.4%), and phenytoin 100 mg (9.4%). In provincial/district hospitals, ASM was provided free of charge. In private pharmacies, affordability for phenobarbital 50 mg and 100 mg was the best, with 0.6 and 0.5 days, respectively, compared to phenytoin 100 mg (1.8 days), and other ASM. No counterfeit ASM was found in this study. Phenytoin sample presented the worst quality (33.0%) compared to carbamazepine (27.8%), and other ASM. SIGNIFICANCE: A lack of access to affordable and effective ASM due to low availability and poor quality of ASM was identified. Our research highlights the need for future policy efforts to ensure the quality of ASM and improve their availability. This can be achieved by involving the calculation of their annual needs for these drugs and increasing the national production of ASM.

Availability, affordability, and quality of essential antiepileptic drugs in Lao PDR.

OBJECTIVE: Epilepsy is a chronic condition treatable by cost-effective antiepileptic drugs (AEDs), but limited access to treatment was documented. The availability and affordability of good quality of AEDs play a significant role in access to good health care. This study aimed to assess the availability, affordability, and quality of long-term AEDs in Lao PDR. METHOD: A cross-sectional study was performed in both public and private drug supply chains in urban and rural areas in Lao PDR. Data on AEDs availability and price were obtained through drug suppliers. Affordability was estimated as the number of day wages the lowest-paid government employee must work to purchase a monthly treatment. Samples of AEDs were collected, and the quality of AEDs was assessed through Medicine Quality Assessment Reporting Guidelines. RESULTS: Out of 237 outlets visited, only 50 outlets (21.1% [95% CI 16.1-26.8]) had at least one AED available. The availability was significantly different between urban (24.9%) and rural areas (10.0%), P = .017. Phenobarbital 100 mg was the most available (14.3%); followed by sodium valproate 200 mg (9.7%), phenytoin 100 mg (9.7%), and carbamazepine 200 mg (8.9%). In provincial/district hospitals and health centers, AEDs were provided free of charge. In other healthcare facilities, phenytoin 100 mg and phenobarbital 100 mg showed the best affordability (1.0 and 1.2 day wages, respectively) compared to carbamazepine 200 mg (2.3 days) and other AEDs. No sample was identified as counterfeit, but 15.0% [95% CI 7.1-26.6] of samples were classified as of poor quality. SIGNIFICANCE: We quantified and qualified the various factors contributing to the high treatment gap in Lao PDR, adding to diagnostic issues (not assessed here). Availability remains very low and phenobarbital which is the most available and affordable AED was the worst in terms of quality. A drug policy addressing epilepsy treatment gap would reduce these barriers.

Differences in knowledge about epilepsy and antiepileptic drugs among pharmacy-dispensing workers in Cambodia and in Lao PDR.

Epilepsy is the most common neurological disorder encountered in primary care in Southeast Asia. People with epilepsy require long-term therapy management. Nonadherence to antiepileptic drugs (AEDs) has been identified as a major factor in suboptimal control of epilepsy. Pharmacies offer patients a first-line point of contact with the healthcare system. Many pharmacies operate with limited or nonqualified human resources that can lead to insufficient knowledge, inappropriate supply of medicines, and insufficient counseling. OBJECTIVE: The aim of this study was to evaluate the qualification and knowledge concerning epilepsy and AEDs among pharmacy-dispensing workers who sell drugs to people with epilepsy. METHOD: A cross-sectional qualitative study was conducted in public and private pharmacies, in both urban and rural areas of Cambodia and Lao People's Democratic Republic (Lao PDR). The knowledge was collected through a questionnaire. RESULTS: A total of 180 respondents from 123 outlets in the two countries were included in this study. A proportion of 40.8% (31) of respondents in Cambodia and 38.5% (40) in Lao PDR were pharmacists, followed by sellers who did not received any healthcare training with a proportion of 18.4% (14) in Cambodia compared to 20.2% (21) in Lao PDR. Head trauma was cited as the main cause of epilepsy by 72.4% (55) in Cambodia and 27.2% (28) in Lao PDR (p < 0.001). Epilepsy was considered as a contagious disease by 6.6% (5) of respondents in Cambodia compared to 18.4% (19) in Lao PDR (p = 0.03). Eighty-seven percent (66) of respondents in Cambodia knew at least one long-term AED versus 67.3% (70) in Lao PDR (p = 0.003). Phenobarbital was mentioned in more than 90.0% of cases in both countries. In overall, 15.4% (21) thought that if seizures are controlled for some months, people with epilepsy could stop taking their AEDs. Only one respondent from Lao PDR was aware of drug-drug interaction between AEDs and oral contraception. CONCLUSION: An educational intervention should be implemented to improve the knowledge of epilepsy and AEDs for pharmacy-dispensing workers. This could include advice for all pharmacy-dispensing workers in order to improve AED management and follow-up of therapeutic adherence.

Explanatory factors of adherence to community-based management of epilepsy in Lao PDR.

RELEVANCE: A low level of knowledge about epilepsy among health workers, a context of stigmatizing sociocultural beliefs, and a low availability of antiepileptic drugs in Lao People's Democratic Republic (PDR) are major gaps in the medical management of people with epilepsy in this country. OBJECTIVES: The principal objective of the study was to identify the associated factors of adherence to community healthcare structures in Lao PDR. Specific objectives were to evaluate patients' adherence status, practices and knowledge about epilepsy and its care, and factors influencing decision-making on therapeutic interventions. MATERIALS AND METHODS: The study was an observational cross-sectional survey about knowledge, attitudes, and practices, handled from February to May 2016. Eighty-seven people with epilepsy were identified in two areas in the periphery of Vientiane Capital through an active screening in villages and homes. Semidirective questionnaires were conducted to collect quantitative and qualitative data. Quantitative analysis included a comparison of adherent vs. nonadherent people with epilepsy, using Chi-square or Fisher's test. Advanced qualitative lexical analysis was carried out on the open-ended questions. RESULTS: Sixty-two people with epilepsy were included and the adherence rate to community care was 67.7%. The only sociodemographic variable that differed significantly between adherent and nonadherent members was the income level (p = 0.015): the wealthiest class of people with epilepsy did not adhere to community healthcare. Eleven percent of people with epilepsy thought that epilepsy was contagious, 80.6% that medication may reduce epilepsy seizure rates, and 33.9% that it was possible to cure epilepsy permanently. Physicians informed about the disease in 69.0% of adherent people with epilepsy and in 40.0% of nonadherent ones (p = 0.029), whereas villagers were involved in 29.0% and 50.0% of cases, respectively. There was a significant difference between the two groups for the prescribed antiepileptic drugs (p = 0.012): phenobarbital covered 73.8% of adherent people with epilepsy but only 40% of nonadherent ones. Half of nonadherent people with epilepsy went regularly to a central hospital in the Vientiane Capital, 15.0% went to Thailand, and 10.0% practiced self-medication in occasional mobilities. CONCLUSION: A wider range of antiepileptic drugs at a reduced cost and the promotion of adherence to community healthcare would allow a better management of people with epilepsy in Lao PDR.

Role of Medicines of Unknown Identity in Adverse Drug Reaction-Related Hospitalizations in Developing Countries: Evidence from a Cross-Sectional Study in a Teaching Hospital in the Lao People's Democratic Republic.

INTRODUCTION: The health dangers of medicines of unknown identity (MUIs) [loose pharmaceutical units repackaged in individual bags without labelling of their identity] have been suspected in L/MICs. Using visual and analytical tools to identify MUIs, we investigated the frequency of, and factors associated with, adverse drug reaction (ADR)-related hospitalizations in a central hospital in Vientiane Capital, Lao People's Democratic Republic (PDR). METHODS: All unplanned admissions, except for acute trauma and intentional overdose, were prospectively recorded during a 7-week period in 2013, leading to include 453 adults hospitalized for ≥24 h. The patients or their relatives were interviewed to complete the study questionnaire. MUIs suspected of being involved in ADR(s) were identified through comparison of visual characteristics of tablets/capsules with that of reference medicines (photograph tool), and by proton nuclear magnetic resonance and mass spectrometry analyses. Factors associated with ADRs were identified by multivariate logistic regression. RESULTS: The frequency of hospitalizations related to an ADR was 5.1% (23/453, 95% confidence interval [CI] 3.1-7.1). Forty-eight (12.8%) patients used MUI(s) in the last 2 weeks preceding hospitalization. They were more likely to be hospitalized because of an ADR (adjusted odds ratio 4.5, 95% CI 1.7-11.5) than patients using medicines of known identity. MUIs were mainly involved in bleeding gastroduodenal ulcers. The photograph tool led to the misidentifications because of look-alike pharmaceutical units in the medicines photograph collection. CONCLUSION: According to the results of this study, there is a need to ensure appropriate labelling of medicines at dispensing and to provide well-suited tools to identify MUIs in clinical settings to improve drug safety and patients' care in developing countries with limited capacities for drug analysis.
