Intermittent Preventive Treatment Versus Scheduled Screening and Treatment of Malaria in Pregnancy (IPTp_IST)

April 10, 2014 updated by: London School of Hygiene and Tropical Medicine

A Trial of Intermittent Preventive Treatment With Sulfadoxine-pyrimethamine Versus Intermittent Screening and Treatment of Malaria in Pregnancy

The incidence of malaria, including the incidence in pregnant women, is declining in many African countries. Thus, there is a need to re-examine the efficacy and cost effectiveness of giving intermittent preventive treatment with sulphadoxine-pyrimethamine in pregnancy (SP-IPTp) on several occasions during pregnancy, an intervention that is threatened by increasing resistance to SP. Possible alternatives to SP-IPTp need to be explored. This applies especially to areas with highly seasonal malaria transmission where women are at risk for only a short period of the year.

The goal of this project is to determine whether in pregnant women who sleep under a long lasting insecticide treated bed net, screening and treatment at each scheduled antenatal clinic visit is as effective in protecting them from anaemia, low birth weight and placental infection as SP-IPTp.

Primigravidae and secundigravidae who present at antenatal clinics in study sites in four West African countries (Burkina Faso, Ghana, Mali and The Gambia) will be randomised to one of two groups. All women will be given a long lasting insecticide treated bed net on first presentation at the antenatal clinic. Women in group 1 (reference group) will receive SP-IPTp according to the current WHO guidelines. Those in group 2 will be screened with a rapid diagnostic test at each scheduled antenatal clinic visit and treated if parasitaemic. Approximately 5000 women will be recruited, 2500 in each group. Women will be encouraged to deliver in hospital where maternal haemoglobin and birth weight will be recorded and a placental sample obtained. Those who deliver at home will be visited within a week of delivery and maternal haemoglobin and infant weight recorded. Mothers and infants will be seen again six weeks after delivery. Also at delivery peripheral maternal blood sample will be obtained for the diagnosis of malaria using RDT, microscopy and PCR. The primary end points of the trial will be birth weight and anaemia at 38 weeks (+/-2 weeks) of gestation. The study is powered to show non-inferiority of group 2 compared to group 1. The costs and cost effectiveness of each intervention will be evaluated.

In the light of recent evidence suggesting that malaria infection during pregnancy, particularly in the last trimester may influence an infant's risk of malaria, we proposed to follow infants born to mothers recruited in the Navrongo site in Ghana who have received either IST or IPTp in pregnancy throughout the whole of their first year of life beyond the six weeks originally proposed. We have received approval for this from the ethic committees at Kwame Nkrumah University of Science and Technology, Ghana Health Service and Navrongo Health Research Centre. The aim is to obtain information on the incidence of both symptomatic and asymptomatic malaria infections in these infants during follow up of the infants.

The study will provide information to national malaria control programmes on whether there are alternative, safe and effective methods to the SP IPTp regimen for reducing the burden of malaria in pregnancy.
