Résumé

We evaluated the performance of a malaria rapid diagnostic test (RDT; Malaria Quick Test(®); Cypress Diagnostic) compared with the standard thick-smear microscopy method using blood samples from human immunodeficiency virus (HIV)-infected individuals and individuals of unknown HIV status collected in Ouagadougou, Burkina Faso. Our results show that 42.1% of 114 HIV-infected patients were concordantly RDT- and thick smear-positive, and 55.3% were concordantly negative. Sensitivity and specificity of the RDT test were 100.0% and 95.4%, respectively, with 5.9% false-positive results and a total agreement of 97.4%; 127 patients with unknown HIV serology were analyzed; of them, 40.9% were RDT- and thick smear-positive, and 46.4% concordantly negative. Sensitivity and specificity were 100.0% and 78.6%, respectively, with 23.5% false-positive results and a total agreement of 87.4%. Malaria Quick Test(®) is rapid and effective for the diagnosis of malaria and has a high sensitivity, confirming its use in general and HIV patients in particular.
