Abstract
Intermittent preventive treatment (IPT) of pregnant women with sulfadoxine-pyrimethamine (SP) is being considered as a routine practice in Madagascar, mainly to decrease the risks of malaria-associated severe anaemia in the women, and of low birthweight in their babies. There is, however, relatively little information available on the efficacy of SP when used, in Madagascar, to treat cases of Plasmodium falciparum malaria. In a preliminary study, carried out in 2003 in the village of Saharevo, 36 uncomplicated cases were each treated with a standard dose of SP and with paracetamol and then followed up for 28 days. No case of therapeutic failure occurred and all the asexual parasitaemias cleared by day 3. It therefore appears that SP is effective against P. falciparum in Saharevo (and probably in the whole, rural district of Moramanga in which the village lies). This is an encouraging observation to make before IPT is initiated throughout the country.
