Performance of the Bioline™ Malaria Ag Pf/Pan and Bioline™ Malaria Ag Pf/Pv for Malaria Diagnostics: Madagascar In-Country Evaluation.
Malaria remains a significant public health concern in Madagascar. The WHO recommends using parasitological methods to confirm Plasmodium infection before treatment. This study evaluated the performance of two rapid diagnostic tests (RDTs), Bioline™ Malaria Ag Pf/Pan (Abbott Point of Care, Princeton, NJ) and Bioline™ Malaria Ag Pf/Pv (Abbott Point of Care, Princeton, NJ), compared with microscopy and polymerase chain reaction (PCR) as reference methods. A prospective, diagnostic performance study was conducted in two malaria-endemic districts with different epidemiological contexts: Ifanadiana (Plasmodium falciparum [P. falciparum] transmission) and Mandoto (Plasmodium vivax transmission). Symptomatic patients and asymptomatic individuals aged 3-81 years were enrolled between April and July 2023. Finger prick blood samples were used for RDTs, Giemsa-stained blood films, and molecular analysis. Among 675 participants (401 symptomatic, 274 asymptomatic), the performance for detecting P. falciparum and non-falciparum/vivax malaria in symptomatic patients for Bioline™ Malaria Ag Pf/Pan was 96.5% (95% CI: 93.4-98.4%) and 91.5% (95% CI: 82.5-96.8%) sensitivity and 76.0% (95% CI: 64.7-85.1%) specificity, and the performance for Bioline™ Malaria Ag Pf/Pv was 95.0% and 91.5% sensitivity and 76.0% specificity. In asymptomatic individuals, the performance was 90.3% (95% CI: 83.4-95.0%) and 33.3% (95% CI: 4.3-77.7%) sensitivity and 85.4% (95% CI: 78.9-90.6%) specificity for Bioline™ Malaria Ag Pf/Pan and 80.6% (95% CI: 80.1-93.1%) and 0% (95% CI: 0-84.2%) sensitivity and 86.0% (95% CI: 79.7-91.0%) and 86.1% (95% CI: 79.7-91.0%) specificity for Bioline™ Malaria Ag Pf/Pv. Rapid diagnostic test performance varies with local epidemiology in symptomatic patients. The results emphasize the need for careful consideration of RDT use based on local epidemiology and clinical context. Both RDTs could be used when microscopy and PCR are unavailable.
期刊介绍：
The American Journal of Tropical Medicine and Hygiene, established in 1921, is published monthly by the American Society of Tropical Medicine and Hygiene. It is among the top-ranked tropical medicine journals in the world publishing original scientific articles and the latest science covering new research with an emphasis on population, clinical and laboratory science and the application of technology in the fields of tropical medicine, parasitology, immunology, infectious diseases, epidemiology, basic and molecular biology, virology and international medicine.
The Journal publishes unsolicited peer-reviewed manuscripts, review articles, short reports, images in Clinical Tropical Medicine, case studies, reports on the efficacy of new drugs and methods of treatment, prevention and control methodologies,new testing methods and equipment, book reports and Letters to the Editor. Topics range from applied epidemiology in such relevant areas as AIDS to the molecular biology of vaccine development.
The Journal is of interest to epidemiologists, parasitologists, virologists, clinicians, entomologists and public health officials who are concerned with health issues of the tropics, developing nations and emerging infectious diseases. Major granting institutions including philanthropic and governmental institutions active in the public health field, and medical and scientific libraries throughout the world purchase the Journal.
Two or more supplements to the Journal on topics of special interest are published annually. These supplements represent comprehensive and multidisciplinary discussions of issues of concern to tropical disease specialists and health issues of developing countries
