Understanding the barriers and facilitators related to never treatment during mass drug administration among mobile and migrant populations in Mali: a qualitative exploratory study.

INTRODUCTION: Five of the neglected tropical diseases use a strategy of preventative chemotherapy distributed via mass drug administration (MDA) for all eligible people living in endemic areas. To be successful, high coverage must be sustained over multiple rounds. Therefore, it will be difficult to reach elimination as a public health problem using MDA if there remain clusters of people who have never been treated. The study aims to explore the reasons why people with high mobility report being never treated during MDA and to provide evidence to support the development of standardised questions for data collection using qualitative research tools. METHODS: We conducted an exploratory study using qualitative methods among displaced people, nomads/transhumants and economic migrants who self-reported that they had never been treated during MDA in the health districts of Tominian and Kalabancoro in Mali. Data were collected through in-depth individual interviews and focus group discussions. Nvivo V.14 software was used for data management and analysis. RESULTS: The main reasons reported for never treatment included: geographical mobility, lack of awareness/information, negative rumours, fear of side effects, conflict and insecurity and logistical difficulties faced in reaching these populations. Proposed solutions included involving communities in the MDA, increasing awareness and information campaigns, effectively managing side effects, and designing and implementing flexible and effective interventions. CONCLUSION: This study highlights that there are people with high mobility who may never have been treated during any round of MDA. The reasons for never treatment highlight the challenges faced when reaching particular groups during MDA activities/interventions. Suggested remedies will require programmes to implement more flexible and tailored interventions. Customised approaches based on the context are essential to guarantee fair access to preventive chemotherapy. Effective interventions must consider the supply and demand side in crafting interventions. This research adds to the evidence base to understand never treatment, particularly among highly mobile population groups and in schistosomiasis elimination programmes.

Effect of Adding a Six-Week Course of Doxycycline to Intensive Hygiene-Based Care for Improving Lymphedema in a Rural Setting of Mali: A Double-Blind, Randomized Controlled 24-Month Trial.

Lymphedema (LE) is one the most disfiguring chronic manifestations of lymphatic filariasis. Its management relies primarily on limb hygiene and local care. A previous study in Ghana demonstrating a beneficial effect of doxycycline on LE led to the current multicenter trial on the efficacy of doxycycline in filarial LE. A randomized placebo-controlled trial was initiated in two rural health districts in Mali. Patients with LE stages 1-3 were randomized to receive either doxycycline (200 mg/day) or placebo over a 6-week monitored treatment period and were then followed every 6 months for 2 years. Both groups received materials for limb hygiene that was carried out daily for the entire 2-year study. The primary endpoint was lack of progression in LE stage at 24 months. One hundred patients were enrolled in each study arm. The baseline sociodemographic characteristics of each group were largely similar. There was no significant difference at month 24 after treatment initiation in the number of subjects showing progression in LE stage between the two treatment arms (P = 0.5921). Importantly, however, the number of attacks of acute adenolymphangitis (ADLA) was reduced in both arms, but there was no significant difference between the two groups at any follow-up time point (all P >0.23). Doxycycline was well tolerated in those receiving the drug. When added to daily self-administered limb hygiene, a 6-week course of doxycycline (200 mg) was not superior to placebo in increasing the improvement associated with hygiene alone in LE volume, stage, or frequency of ADLA attacks over a 24-month period.

Knowledge and factors influencing schistosomiasis control interventions in the hyperendemic health district of Kalabancoro in Mali, 2020.

Introduction: schistosomiasis is a public health concerns in many countries including Mali. In Kalabancoro District, during the 2017 assessments, the National schistosomiasis and soil-transmitted helminths control program reported prevalence´s of 10.83% and 50.83% for urinary schistosomiasis and intestinal schistosomiasis respectively. This district recorded the highest prevalence of intestinal schistosomiasis among the 46 districts evaluated. To better understand these high rates, this study investigated the knowledge of schistosomiasis in children and adults in this district. Methods: a cross-sectional study was conducted which involved 947 participants. A univariate analysis and multiple logistic regression were performed. Data collection was through questionnaire administration. Results: during the study, 76.1% of participants claimed to know about schistosomiasis (p<0.001) among them, 85.6% did not know the mode of contamination (p=0.001) and 66.3% knew the traditional treatment (p=0.004). Participants whose households were close to water impoundment were 2.16 times more likely to know schistosomiasis than those who were not (95% CI = [1.49 - 3.11]). Conclusion: most of the majority of participants reported being aware of schistosomiasis. However, the modes of transmission, prevention, and treatment of schistosomiasis were not well known. Misconceptions persist, hindering effective prevention and control. This is a tangible obstacle to the elimination of schistosomiasis in the Kalabancoro Health District and requires interventions tailored for these endemic communities.
