Clinical Trial Summary

Malaria remains a disease that causes much death and sickness, especially in sub-Saharan Africa. An accurate, simple, and inexpensive method of diagnosing malaria is urgently needed. The purpose of this study is to evaluate a different diagnostic method compared to those most frequently used. The study may also identify the factors causing false positive and false negative results using the alternative method. Participants will be 600 Ugandan children aged 1-10 years who are enrolled in protocol 04-068. Those who develop a fever over the 12 month duration of the study will be tested for malaria by both the standard and the new methods. These tests will require a few drops of blood to be collected by finger prick. Subjects will be treated on the basis of standard diagnostic testing (i.e. expert microscopy).


Clinical Trial Description

Malaria remains one of the most devastating infectious diseases, causing high morbidity and mortality especially in sub-Saharan Africa. The need for an accurate, simple, and inexpensive method to diagnose malaria has become increasingly urgent. Rapid diagnostic tests (RDTs), based on detection of Plasmodium antigens, may represent a more practical diagnostic tool than traditional light microscopy. This longitudinal study's objectives are (1) to evaluate the clinical performance (sensitivity, specificity, positive and negative predictive values) of RDTs, as compared with presumptive diagnosis and microscopy, for the diagnosis of malaria in children in Kampala, Uganda, and (2) to identify host and test factors that lead to false positive and false negative RDT results by comparison with polymerase chain reaction (PCR) analysis. Study subjects in this RDT study will have already been enrolled in a larger on-going longitudinal study of antimalarial drug efficacy, tolerability, and safety that began at the Kampala study site in late 2004. In the RDT study, over a one-year period, study participants' blood samples will be evaluated with the current gold standard for malaria diagnosis (microscopy) as well as two types of RDT whenever they present with a new fever episode (the first fever after study enrollment, or a fever that occurs more than 14 days after the patient's most recently diagnosed episode of malaria). As part of the on-going longitudinal drug efficacy trial, probability sampling was used to select a random sample of 600 children, who will be followed for three years for all their health-care needs. The RDT study will involve evaluation of the cohort over 12 months, beginning in approximately the third quarter of 2005. This protocol is a substudy of 04-068. ;
