ABSTRACT
Background & objectives: Conflicting reports exist regarding the HIV-1 infection on the risk of malaria. A transient almost one-log elevation in HIV viral load occurs during febrile malaria episodes. We prospectively studied malaria patients for HIV infection from Mumbai. Methods: A total of 171 malaria patients and 28,749 normal voluntary blood donors were studied for their HIV status. Diagnosis of malaria was done by microscopical examination of blood. HIV screening was done by detection of HIV-1 & 2 antibodies by micro well ELISA using Enzaids & J Mitra kits followed by confirmation using western blot (Innogenetics, Belgium) analysis. Results: Out of 171 malaria patients 13 (7.6%; Odds ratio= 4.45; p <0.0001) and 521 blood bank donors were found to be HIV reactive. Among 13 HIV reactive patients, eight patients were Elisa borderline reactive and western blot positive (p24), which may be due to cross-reactive antibodies. Five of 13 malaria patients found to be HIV-1 positive by ELISA and by western blot confirming HIV and malaria co-infection. Conclusion: Our findings suggest that HIV-1 and malaria co-infection can’t be ruled out in malaria endemic countries like India.
