There are about 292 clinical studies being (or have been) conducted in Zambia. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This is a randomized placebo controlled trial. Malaria chemoprophylaxis with mefloquine in asymptomatic HIV-infected adults living in a malaria endemic region of Luanshya, Zambia will be compared to a placebo control group and followed up for 18 months.
To compare Azithromycin plus Chloroquine versus Mefloquine to treat uncomplicated plasmodium falciparum malaria.
The WHO Special Programme for Research and Training in Tropical Diseases (TDR) developed a Community-Directed Treatment (COMDT) approach, which has been adopted in the control of onchocerciasis and lymphatic filariasis. WHO has recommended the use of COMDT approach in the control of schistosomiasis and STH infections. The COMDT approach has been compared with the school based programmes in certain African countries,but not with the health-facility based approach. The project will be implemented in Mazabuka district of Zambia where COMDT approach will be implemented in the catchment area of Rural Health Centres (RHC) as a supplement to the health-facility-based approach. After each round of treatmenttreatment coverage and factors responsible for the treatment coverage will be measured in both areas. The health impact of the health facility based approach with and without the COMDT approach will be compared. The effect of the COMDT as a control approach of STH infections will be monitored on infections in the community of children aged 12 to 59 months.
The study is designed as a randomized, controlled trial with specific observational objectives. All HIV-seropositive pregnant subjects electing to breastfeed their child will be counselled to exclusively breastfeed through 4 months of age. All live-born children will be randomized (1:1) at birth to one of two counseling programs: A) to encourage abrupt weaning at 4 months of age, or B) to encourage exclusive breastfeeding through 6 months of age with the introduction of typical weaning foods ad lib.
A single dose of nevirapine (SD NVP) given to an HIV infected pregnant woman followed by a single dose to her infant has been shown to be an effective way of reducing the risk of mother-to-child transmission (MTCT) of HIV. The purpose of this study was to compare the effectiveness of a non-nucleoside reverse transcriptase inhibitor (NNRTI)-based antiretroviral regimen versus a protease inhibitor (PI)-based regimen in HIV infected infants who had or had not been exposed to SD NVP for prevention of MTCT. >> >> A five year follow up has been added to the study.
The purpose of this study is to determine the safety and efficacy of sulfadoxine-pyrimethamine (SP) versus artemether-lumefantrine (Coartem) when administered to HIV+ and HIV- patients with uncomplicated P. falciparum malaria. Patients will be randomised to one of the 2 treatment and followed up (until day 14 actively) for 45 days.
The objectives of this study is: - to establish the coverage rate of weekly iron supplementation in children in intervention schools over a period of nine months - document any side effects of weeekly iron supplementation among children in intervention schools over a period of nine months asses the feasibility of incorporating the weekly iron supplementation programme into the normal school activity in intervention schools determine the extent of acceptability and support for the iron supplementation programme by staff at the health centre nearest to the intervention schools - compare the praziquantel efficacy and schistosomiasis reinfection in children in intervention schools with that of children in control schools following the introduction of weekely iron supplementation over a period of nine months - determine the impact of weekly iron supplementation on haemoglobin levels of children in intervention schools and compare with children in control schools over a period of nine months
Prevention of malaria in pregnancy is critical given the high incidence of malaria in Zambia and its serious impact on both maternal and infant survival. Intermittent presumptive treatment with sulfadoxine-pyrimethamine has been shown to be highly efficacious for reducing the risk of malaria in pregnancy. However, based on a study done in western Kenya, HIV-infected pregnant women may need more frequent dosing of SP, i.e., on a monthly basis rather than the standard 2-dose regimen given during the second and third trimesters, as HIV appears to reduce the effectiveness of the SP drug combination. The goal of this study was to evaluate the efficacy of the standard dosing regimen in comparison to an intensive monthly SP dosing schedule in HIV-positive women.
The objective of the study is to determine the efficacy and safety of 0.5% and 2% PRO 2000/5 gels compared to placebo in preventing vaginally acquired HIV infection.
We conducted a longitudinal study to assess the immunogenicity of standard-titer measles vaccine in HIV-infected and uninfected Zambian children. The study hypothesis was that HIV-infected children would have higher rates of primary and secondary measles vaccine failure compared to uninfected children, contributing to decreased levels of population immunity to measles and facilitating measles virus transmission in regions of high HIV prevalence.
