Condition(s) targeted: Malaria; Malaria in Pregnancy

Intervention: Sulphadoxine-pyrimethamine (Drug); Chloroquine prophylaxis (Drug)

Phase: Phase 4

Status: Terminated

Sponsored by: Ministry of Health and Medical Services, Solomon Islands

Official(s) and/or principal investigator(s):

The purpose of this study is to assess the effectiveness of intermittent preventive treatment in pregnancy (IPTp) with Sulphadoxine-pyrimethamine compared to chloroquine prophylaxis in Honiara, Solomon Islands for prevention of malaria and it's adverse effects in pregnancy.

Clinical Details

Official title: Intermittent Preventive Treatment With Sulfadoxine-Pyrimethamine Versus Weekly Chloroquine Prophylaxis During Pregnancy in Solomon Islands: a Randomized Controlled Trial

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Prevention

Primary outcome: Placental malaria among primigravidae at time of delivery

Secondary outcome:

Low birth weight among primigravidae

Maternal anaemia (Hb <11 g/dl) in the third trimester

Maternal anaemia (Hb <11 g/dl) at delivery

Malaria parasitemia at delivery

Detailed description: Malaria is a major health problem in the Solomon Islands, with an annual estimated incidence of 158 per 1000 population in 2005, and P. falciparum and P. vivax responsible for respectively 71% and 29% of the clinical cases. Not much is known about the burden of malaria in pregnancy and the effectiveness of weekly chloroquine prophylaxis, the national policy for the prevention of malaria in pregnancy. In Honiara, the capital, 42. 7% of the pregnant women are anaemic at their first antenatal clinic (ANC) visit. In a national data-base, clinical malaria in pregnancy was associated with an increased risk of anaemia. High levels of chloroquine drug resistance have been reported (67% treatment failure at day 28 in 2001). Among women who attended an ANC in Honiara and had been offered chloroquine prophylaxis, a high low birth weight risk among primigravidae compared to multigravidae was noted. This information indicates that the current policy may not be optimal for the prevention of malaria and its effects in pregnancy. Intermittent preventive treatment (IPTp) with sulfadoxine-pyrimethamine (SP) in pregnancy is an alternative strategy which has been introduced in many malarious countries in sub-Saharan Africa. Studies which compared IPTp with chloroquine prophylaxis in Africa showed that IPTp was more beneficial. Resistance to SP monotherapy in the Solomon islands has not been examined; however, the resistance to the combination of SP and chloroquine is low (< 10%). IPTp with SP has so far not been implemented in a region where P. vivax is common, and the effect of SP on P. vivax is not clear. We propose a randomized controlled trial to assess the effectiveness of IPTp with SP compared to chloroquine prophylaxis in Honiara, the Solomon Islands. As outcome measures we will examine the effect on anaemia in third trimester, placental malaria, maternal anaemia at the time of delivery, infant birth weight, and prematurity. Outcomes in women allocated IPTp with SP will be compared with those allocated chloroquine prophylaxis. We expect 2504 women from Honiara City Council to participate in the randomised controlled trial. To assess the burden of malaria in pregnancy in other locations women we expect 1000 women to participate in a survey at the time of delivery among women not participating in the trial. At the end of this study, we will know the burden of malaria in pregnancy in Honiara and Guadalcanal, and we will be able to assist in developing evidence based national guidelines for malaria prevention among pregnant women in the Solomon Islands. The information obtained will be important for other areas and countries with a similar epidemiology of malaria in pregnancy.
