Efficacy of Intermittent Screening and Treatment or Intermittent Preventive Treatment (IPT) With Dihydroartemisinin-Piperaquine, Versus IPT With Sulfadoxine-Pyrimethamine for the Control of Malaria in Pregnancy in Kenya
Summary
Malaria in pregnancy (MiP) due to Plasmodium falciparum infection is a major cause of maternal morbidity and poor birth outcomes. Intermittent preventive treatment in pregnancy (IPTp) with Sulfadoxine pyrimethamine (SP), the administration of SP at predefined intervals in the second and third trimesters of pregnancy irrespective of the presence of malaria parasitemia, is currently recommended for HIV-negative women in all areas with stable moderate to high transmission of malaria. Due to increasing resistance to SP, it is no longer used as a treatment for symptomatic malaria, and the efficacy of IPTp-SP seems to be decreased. This study aims to look at a new drug, Dihydroartemisinin-Piperaquine (DP) for IPTp, as well as to explore the strategy of intermittent screening and treatment in pregnancy (ISTp) with DP. This strategy uses increased screening at time of focused antenatal care (FANC) with treatment of women who screen positive. The hypothesis is that the efficacy of both IPTp-DP and ISTp-DP will be associated with a reduction in malaria infection at delivery among HIV(-) women when compared to IPTp-SP, in an area with decreasing malaria transmission and high levels of SP resistance in Kenya.
