Community-based management of epilepsy in Southeast Asia: Two intervention strategies in Lao PDR and Cambodia

The challenges of detecting Taenia solium and neurocysticercosis in low and middle-income countries: A scoping review of Lao People's Democratic Republic

OBJECTIVE

Taenia solium is a tapeworm of global importance due to the burden of disease associated with human epilepsy caused by neurocysticercosis. Unfortunately, diagnostic challenges impede control efforts in many low and middle-income countries. This review examines publications concerning Taenia species in the Lao PDR with a focus on T. solium to inform future research and control programmes.

METHODS

PubMed and Scopus databases were primary sources of evidence. Publications must have reported taeniasis or T. solium results from Lao PDR. Publications repeating results or samples were combined into unique projects.

RESULTS

A total of 64 publications were included and summarised into 46 projects. The majority of projects applied faecal microscopy as their only diagnostic technique. As a result, the specific species of Taenia was often not determined. Only five projects used molecular techniques to identify the species observed. Only case report of neurocysticercosis has been published. The northern region was included in half the number of projects compared to the south, despite being a high-risk area T. solium.

CONCLUSIONS

The diagnostic challenge of determining the species of Taenia present in a faecal sample presents a significant limitation to the control of T. solium in Lao PDR and is an experience that is relevant to many other low and middle-income countries. There must be an improved understanding of the distribution and frequency of T. solium if disease control efforts are to be intensified to reduce the burden of neurocysticercosis, as encouraged by WHO and others. It is hoped that this can be achieved through non-biological risk mapping tools and the more frequent application of molecular tools to routine sample collection. Diagnostic tools that are applicable to low resource settings should be a priority area of research for T. solium.

Diagnosis of Epilepsy by Traditional Healers and Its Implications on Management in the Selected Rural Communities of Limpopo and Mpumalanga Provinces: A Qualitative Study

Introduction

Epilepsy is a neurological disorder which causes seizures and may be accompanied by loss of unconsciousness and control of bowel or bladder function. However, other types of epilepsy are only characterised by rapid blinking or a few seconds of staring into space. Many people living with epilepsy in rural communities consult traditional healers as their first line of treatment for epilepsy. Second preference is given to medical practitioners which causes unnecessary delay in the early diagnosis and treatment of epilepsy. This study aimed to explore how traditional healers diagnose epilepsy and its implications on management in the selected rural communities of Limpopo and Mpumalanga Provinces.

Methods

A qualitative approach using explorative, descriptive and contextual designs was adopted. Purposive sampling was used to sample six villages in Limpopo and Mpumalanga Provinces. Snowball sampling was used to sample twenty traditional healers. Data were collected through in-depth individual interviews at the participant's homes. Data were analysed using Tesch's eight steps of open coding data analysis.

Results

This study found that traditional healers have varied beliefs and misconceptions regarding the causes and diagnosis of epilepsy, hence this greatly influencing the management. The misconceptions on the causes include a calling by ancestors, urine contents, snake in the stomach, contaminated digestive system and witchcraft. The management included using herbal plants, insects, foam excreted during seizures and urine of the person living with epilepsy.

Recommendation

It is recommended that for effective management of epilepsy, there should be coordination between traditional healing and western medicine. Future research should look at the integration of traditional medicine and western medicine.

A cluster-randomized trial comparing home-based primary health care and usual clinic care for epilepsy in a resource-limited country

OBJECTIVE

To ascertain whether home-based care with community and primary healthcare workers' support improves adherence to antiseizure medications, seizure control, and quality of life over routine clinic-based care in community samples of people with epilepsy in a resource-poor country.

METHODS

Participants included consenting individuals with active epilepsy identified in a population survey in impoverished communities. The intervention included antiseizure medication provision, adherence reinforcement and epilepsy self- and stigma management guidance provided by a primary health care-equivalent worker. We compared the intervention group to a routine clinic-based care group in a cluster-randomized trial lasting 24 months. The primary outcome was antiseizure medication adherence, appraised from monthly pill counts. Seizure outcomes were assessed by monthly seizure aggregates and time to first seizure and impact by the Personal Impact of Epilepsy scale.

RESULTS

Enrolment began on September 25, 2017 and was complete by July 24, 2018. Twenty-four clusters, each comprising ten people with epilepsy, were randomized to either home- or clinic-care. Home-care recipients were more likely to have used up their monthly-dispensed epilepsy medicine stock (regression coefficient: 0.585; 95% confidence intervals, 0.289-0.881; P = 0.001) and had fewer seizures (regression coefficient: -2.060; 95%CI, -3.335 to -0.785; P = 0.002). More people from clinic-care (n = 44; 37%) than home-care (n = 23; 19%) exited the trial (P = 0.003). The time to first seizure, adverse effects and the personal impact of epilepsy were similar in the two arms.

SIGNIFICANCE

Home care for epilepsy compared to clinic care in resource-limited communities improves medication adherence and seizure outcomes and reduces the secondary epilepsy treatment gap.

Seizure remission rates remain low in a resource-limited country, a multicentre comparison study in Malaysia

Seizure remission rates of 60% with antiseizure medications were reported in developed countries, but might be lower in resource-limited countries. The challenges in epilepsy care in resource-limited regions were highlighted 10 years ago, and still remain an ongoing issue. This study aimed to determine the seizure freedom rates in level-2 epilepsy care centres (centres with general neurologists) compared to level-3/4 centres (centres with epileptologists providing epilepsy surgery evaluation) in Malaysia. This is a retrospective study of 1,347 adult epilepsy patients from two level-2 (n = 290) and two level-3/4 epilepsy care centres (n = 1,057). The seizure remission rates were significantly lower in level-2 centres (42.5%) compared to the level 3/4 centres (61.9%, p < 0.05). Level-2 centres had significantly more patients with undetermined seizure types compared to level-3/4 centres (6.6% vs 3.1%, p < 0.05). Level-3/4 centres had significantly more patients with epilepsy of structural and genetic origins, whereas more patients in level-2 centres had unknown aetiology (46.2% vs. 34.0% in level-3/4, p < 0.05). Level-2 centres had a lower neurologist-to-patient ratio (1:97 vs. 1:50 in level-3/4 centres, p < 0.05). Level-2 centres also had fewer patients, who underwent investigations such as EEG (74.1% vs. 89.6%) and brain MRI (54.1% vs. 72.4%, p < 0.05) in comparison with level-3/4 centres. Our study emphasized the existing challenges in epilepsy care in a resource-limited country to achieve the ideal 60% seizure remission rate.
