Anemia Clinical Trial

Official title:
Epidemiology of Malaria in Malawi: Human Hosts and Parasites in Three Districts Part 2: Cross-sectional Surveillance (School-based Cohorts)

Clinical Trial Summary

A school-based, prospective, cohort study was conducted to evaluate the epidemiology of P. falciparum (Pf) infections in school-age children and determine the impact of the screen-and-treat approach on Pf infection and anemia prevalence among students in two different transmission settings. Investigators aimed to evaluate how frequently malaria rapid diagnostic tests (mRDTs) fail to detect low-parasite-density infections as well as whether low-density infections contribute to the burden and health consequences of Pf infection in school-age children and whether they contain gametocytes, the parasite stage required for transmission from humans to mosquitos.

Clinical Trial Description

Students were enrolled in four schools in southern Malawi in the rainy (March-May) and dry season (Sept-Nov) of 2015. 15 students per grade-level (grades 1-8), were invited to participate. Following enrollment, students were evaluated at baseline for screening-and-treatment, and followed-up 1, 2 and 6 weeks later. At each follow-up visit, a blood sample was obtained for microscopy and molecular detection of parasites and students were interviewed about bed net use the night prior, current or recent illness, and use of antimalarial treatment. At the final visit, a mRDT and hemoglobin test were repeated, and parents were interviewed and portable medical records ("health passports") were reviewed to identify intercurrent fever or malaria treatment. ;
