Operational research to develop an M&E study to guide a triple drug stopping decision for lymphatic filariasis in India

What is the indicator(s) and accompanying M&E strategy that enables country programs to determine when the risk of ongoing transmission of LF has been reduced so that IDA can be stopped with little risk of resurgence of transmission?

Mf Clearance post-IDA in Samoa

What is the effectiveness of appropriately dosed IDA in clearing microfilariae (Mf) from Mf positive people who (i) reported taking triple drug therapy with ivermectin, diethylcarbamazine, and albendazole (IDA) in August 2018, and (ii) did not report recently taking IDA.

This will be investigated by:

  • assessing the baseline (current) Mf presence and density before re/treatment with IDA, against which post-treatment Mf presence and density can be compared
  • assessing the peak plasma concentration levels of ivermectin, DEC and albendazole in treated Mf positive individuals to identify whether the recommended dosages of medications are sufficient for achieving effective plasma concentrations
  • assessing Mf clearance one week following directly observed IDA re/treatment
Countries: Samoa

Assessing drug coverage following mass drug administration to monitor the impact of the WHO recommended three-drug regimen of ivermectin, diethylcarbamazine, and albendazole for the elimination of lymphatic filariasis

To validate the reported coverage of the 2018 mass drug administration in American Samoa in order to assess the impact of triple drug therapy with ivermectin, diethylcarbamazine, and albendazole (IDA) for lymphatic filariasis  on infection prevalence

Is Preventive Chemotherapy for NTDs Really “Pro-Poor?”: Insights from the Demographic and Health Surveys

To use DHS data from 40 countries to examine the extent to which deworming of children 1-4 years is associated with: 1) a range of individual- and family-related socioeconomic indicators, including wealth quintile and maternal education; and 2) access to health systems that could provide opportunities for deworming, independent of family-level socioeconomic status.
