Increased prevalence of malaria in HIV‐infected pregnant women and its implications for malaria control

Abstract

HIV infection is associated with a significant increase in malaria prevalence in pregnant women of all parities with the effect apparent from early in gestation. Two treatment doses of sulphadoxine-pyrimethamine were inadequate to clear parasitaemia in many women by the time of delivery and this occurred independently of HIV status and despite high sensitivity to SP in this area. There is a need to undertake longitudinal studies to determine the incidence of P. falciparum infection in HIV-infected and uninfected pregnant women and to reassess the frequency and timing of sulphadoxine-pyrimethamine treatment doses in these women. Late pregnancy re-infections with P. falciparum probably explain the high parasite prevalence at delivery following sulphadoxine-pyrimethamine treatment at 28-34 weeks gestation.
