NCT ID: NCT01053325 Completed - HIV Infections Clinical Trials

Establishing Effectiveness of Daily Co-trimoxazole Prophylaxis For Prevention of Malaria in Pregnancy

Start date: September 2010
Phase: Phase 3
Study type: Interventional

Malaria is a major contributor of disease burden in Sub-Saharan Africa: 90% of global cases occur there, and pregnant women and children under 5 years are the most vulnerable. Malaria in pregnancy increases risks of abortion, stillbirth, prematurity, intrauterine growth retardation and maternal anemia, and is associated with higher risk of low birth weight and perinatal, neonatal and infant mortality. For prevention and control of malaria in pregnancy, the WHO recommends Intermittent Preventive Treatment (IPT) with antimalarial drugs, insecticide treated nets (ITNs) and effective treatment of malaria and anemia. HIV in pregnancy increases the risks of malaria, and it seems that the efficacy of IPT with the drug sulphadoxine-pyrimethamine (SP) is decreased in HIV+ pregnant women. Malaria prevention in pregnancy in Zambia relies on ITNs and IPT with SP. Daily prophylaxis with cotrimoxazole (CTX) effectively reduces mortality and morbidity in HIV+ individuals, and antibiotic therapy during pregnancy might help to decrease adverse pregnancy outcomes. CTX prophylaxis improves birth outcomes in HIV+ women with CD4<200/µl: a study concluded that antenatal provision of CTX was beneficial for HIV+ pregnant women with low CD4 but not in women with ≥200/µl (however, this study was carried out in an area with very low risk of malaria , and CTX may have a different effect depending on endemic conditions). The WHO recommends daily CTX in addition to ARVs, to prevent opportunistic infections in all HIV+ patients. Concurrent administration of SP and CTX may increase the incidence of severe adverse reactions in HIV+ patients, so WHO has promoted CTX prophylaxis as an alternative to SP for the IPT in immuno-compromised pregnant women. Unfortunately, there is insufficient information on the effectiveness of daily CTX for preventing malaria infection in pregnancy: so, SP is still the only antimalarial recommended by WHO for this purpose. With the increase in SP resistance and with the newer antimalarials still being studied for safety and efficacy in pregnancy, CTX could be an alternative for SP in reducing malaria and malaria-related morbidity and mortality in pregnancy. This study will try to to see if in HIV- and HIV+ pregnant women, CTX is not inferior to SP in reducing placental parasitaemia. Such information is needed to issue updated, effective guidelines on malaria prevention in pregnancy

The purpose of this study is to evaluate the efficacy of cotrimoxazole prophylaxis in prevention of malaria during pregnancy in HIV-infected women, compared to intermittent preventive treatment with mefloquine.

NCT ID: NCT00852423 Completed - Clinical trials for Malaria in Pregnancy

Safe and Efficacious Artemisinin-based Combination Treatments for African Pregnant Women With Malaria

PREGACT
Start date: June 2010
Phase: Phase 3
Study type: Interventional

Malaria is the most important human parasitic disease and is responsible of high morbidity and mortality in resource-poor countries. Pregnant women, who are a high-risk group, are almost always excluded from clinical trials; thus, the investigators lack sufficient information on the safety and efficacy of most antimalarials in pregnancy. The recommendation of the World Health Organization to use artemisinin combination therapy (ACT) in the 2nd and 3rd trimester is already implemented in several African countries, however documentation of their efficacy and safety in pregnancy is still limited. Thus, the investigators propose to evaluate the efficacy and safety of 4 ACT(artemether-lumefantrine, amodiaquine-artesunate, mefloquine-artesunate and dihydroartemisinin-piperaquine), when used to treat pregnant women with P. falciparum malaria; the results will help to recommend the optimal therapy for this high-risk group in Africa.

New Approaches to Improve Coverage and Compliance of Antimalarial Treatment for Pregnant Women in Rural Africa

Start date: March 2004
Phase: Phase 3
Study type: Interventional

Malaria in pregnancy contributes substantially to maternal anaemia and low birth weight: effective malaria control in pregnancy could avoid about 10,000 maternal and up to 200,000 infant deaths every year. Intermittent preventive treatment with the drug sulfadoxine-pyrimethamine (IPTp-SP), administered at least twice during routine antenatal clinics, is recommended by the World Health Organization for areas of moderate to high malaria transmission, including Sub-Saharan Africa. Studies carried out in Kenya and Malawi before 2004 had showed that two doses of IPTp-SP significantly reduce maternal anaemia, placental malaria parasitaemia and low birth weight. However, in countries where this strategy had been introduced as part of national policy, the coverage of the target population has varied widely, with estimates of 33-93% for uptake of one dose and 24-68% for two doses, and no country had reached the goal of 80% of pregnant women receiving at least 2 doses of IPTp. New approaches designed to improve IPTp coverage were therefore urgently needed. This study was therefore set up in 2002, in order to evaluate the additional effect of a targeted promotional campaign on antenatal clinics utilization and on coverage and uptake of Intermittent preventive treatment with sulfadoxine-pyrimethamine in a rural health district in Burkina Faso; and to investigate the effectiveness of intermittent preventive treatment with the sulfadoxine-pyrimethamine compared with weekly chloroquine, in order to provide additional evidence to the Burkinabé Ministry of Health for an impending policy change.

NCT ID: NCT00680732 Completed - Malaria Clinical Trials

Prevention of Intrauterine Growth Retardation in Burkina Faso: the Malaria Component

Start date: June 2003
Phase: Phase 4
Study type: Interventional

Our objective was to investigate the importance of malaria infection/disease during pregnancy and more particularly during the first trimester; we also looked at the maternal-foetal interactions and their influence on the subsequent child's response to malaria infections during the first year of life. This study was carried out !in the same population recruited for the IUGR study (NCT00642408).

NCT ID: NCT00140517 Completed - Anaemia Clinical Trials

Relationships Between the Use of Antimalarial Drugs in Pregnancy and Plasmodium Falciparum Resistance

Start date: October 2002
Phase: N/A
Study type: Interventional

Plasmodium falciparum resistance to chloroquine (CQ) and sulfadoxine-pyrimethamine (SP) continue to spread, impeding control of this important disease. CQ and SP are still the most commonly used antimalarial drugs for malaria prevention during pregnancy and might be made less effective by resistance. However, the treatment and prophylaxis regimens used may also create conditions for selecting resistant malaria parasite strains. A better understanding of the relationships between chemoprophylaxis regimens and resistance would be helpful to improve chemoprophylaxis of malaria in pregnancy. This work aims to improve the use of chemoprophylaxis in pregnancy by determining whether there is a relationship between the use of standard prophylactic regimens with CQ and SP and the occurrence of P. falciparum resistant strains in pregnant women. The study consists of 2 parts. The first part is a randomized trial comparing 3 chemoprophylactic treatment groups: - weekly CQ after initial presumptive CQ treatment, - CQ intermittent presumptive treatment given as a standard dose at 2nd and 3rd trimester, respectively and SP intermittent presumptive treatment given as a single dose at 2nd and 3rd trimester, respectively. These treatment groups will also be compared to a group of women delivering at the same health centre but who have not been participating in the study. The second part will be a clinical trial for assessment of clinical and parasitological efficacy of CQ and SP treatment in pregnant women presenting with uncomplicated malaria attacks. The study will be conducted from October 2002 to March 2005 in a health centre of Ouagadougou, Burkina Faso where malaria transmission is seasonal and resistance to CQ and SP is low.

NCT ID: NCT00132535 Completed - HIV Infections Clinical Trials

Influence of Chloroquine on HIV Viral Load Among Pregnant Women in Uganda

Start date: August 2003
Phase: N/A
Study type: Interventional

There is conflicting evidence regarding the influence of HIV infection on the success of malaria prevention in pregnancy and effect on pregnancy outcome. The purpose of the proposed study is to assess the impact of HIV infection on the effectiveness of malaria prevention during pregnancy. This will be carried out by comparing two intermittent preventive treatments (IPTs) with sulfadoxine/pyrimethamine (SP) plus 300 mg weekly chloroquine with two doses IPT plus a weekly chloroquine placebo. The emphasis will be on assessing the effect of chloroquine on HIV viral load and malaria morbidity and foetal outcome. The study will be a randomised double-blind placebo-controlled trial with two arms, involving pregnant women attending antenatal classes (ANCs) at health units, enrolled early in their second trimester at 3 health units of the Mbarara district and Kampala. All pregnant women presenting for antenatal care, irrespective of parity, who consent to participate will be enrolled. Women with severe systemic disease or symptoms of AIDS will be excluded from the study data analysis. Women will be screened for HIV status and their HIV viral loads will be measured at enrolment. Parasitaemia will be assessed at enrolment; at the beginning of the third trimester; and at delivery. Haemoglobin will be measured at the same time points. The main outcome variables to be assessed will be maternal peripheral parasitaemia; placental parasitaemia; maternal clinical malaria; congenital parasitaemia; and maternal and neonatal haemoglobin, birth weight and viral load at enrolment and before nevirapine administration to the HIV positive mothers at birth. Anthropological pre-studies to assess the quality of ANC services and healthcare seeking practices of pregnant women in the study area will be carried out. Focus group discussions (FGD) with pregnant women and mothers of neonates; in-depth interviews with relevant health workers; and illness narratives from pregnant women will be used to collect data. The anthropological study results will assist in appropriately planning for the trial to enhance compliance to the intervention. The data collection is planned to commence in August 2003 and is expected to end in October 2005. Twelve months will be spent on the write-up phase.
