Article Synopsis
  • The study explores the potential benefits of using whole genome sequencing of Mycobacterium tuberculosis to improve tuberculosis case detection in high-incidence areas, as previous research has shown its effectiveness in identifying outbreaks and transmission events.* -
  • A cluster randomized controlled trial will take place in 48 rural village groups in Madagascar, comparing three intervention methods: standard care with microscopy, active case finding with PCR testing, and a novel approach that includes both PCR testing and genome sequencing.* -
  • The primary goal is to assess the number of tuberculosis cases detected per 100,000 people after one year of different interventions, aiming to enhance understanding of how genomic tracking can improve tuberculosis management in regions with high disease levels.*

Introduction: A prototype lateral flow device detecting cytokine biomarkers interleukin (IL)-1α and IL-1β has been developed as a point-of-care test-called the Genital InFlammation Test (GIFT)-for detecting genital inflammation associated with sexually transmitted infections (STIs) and/or bacterial vaginosis (BV) in women. In this paper, we describe the rationale and design for studies that will be conducted in South Africa, Zimbabwe and Madagascar to evaluate the performance of GIFT and how it could be integrated into routine care.

Methods And Analysis: We will conduct a prospective, multidisciplinary, multicentre, cross-sectional and observational clinical study comprising two distinct components: a biomedical ('diagnostic study') and a qualitative, modelling and economic ('an integration into care study') part.

Background: Among the many collaterals of the COVID-19 pandemic is the disruption of health services and vital clinical research. COVID-19 has magnified the challenges faced in research and threatens to slow research for urgently needed therapeutics for Neglected Tropical Diseases (NTDs) and diseases affecting the most vulnerable populations. Here we explore the impact of the pandemic on a clinical trial for plague therapeutics and strategies that have been considered to ensure research efforts continue.

Background: Bubonic plague is the primary manifestation of infection with Yersinia pestis, accounting for 90% of all plague cases and with 75% of global cases reported in Madagascar. All drugs in use for treating plague are registered based on experimental data and anecdotal evidence, and no regimen currently recommended is supported by a randomized clinical trial. The IMASOY trial intends to fill this knowledge gap by comparing two 10-day regimens included in the national guidelines in Madagascar.
