There are about 249 clinical studies being (or have been) conducted in Ghana. 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 randomised controlled trial aimed to verify whether directly observed single dose treatment (with tinidazole+fluconazole) would be as effective as the longer standard treatments (metronidazole for 7 days, plus vaginal clotrimazole for 3 days) in the syndromic management of women presenting with vaginal discharge in primary health care centers of Ghana, Togo, Guinea and Mali. It was designed as an effectiveness trial, i.e. it was done under conditions typical of routine work in these health centers
A study that seeks to establish an effective way of preventing anaemia in children at the community level using two known interventions - Iron supplementation and or antimalarial. Children recruited into the study will be assigned to four groups. Those receiving Placebo and Iron, those receiving Placebo and Antimalarial, those receiving Placebo and Antimalarial and those receiving double placebo. The children will be followed up over a period of nine months and their haemoglobin concentration, malaria parasites in their blood and their weight and height will be assessed.
The primary purpose of this study was to determine the safety and tolerability of moxidectin in subjects infected with Onchocerca volvulus (a parasitic worm).
Malaria is one of the major causes of illness and mortality in Sub-Saharan Africa. In Ghana, malaria is the most important cause of morbidity and accounts for about 40% of outpatient contacts. Chemoprophylaxis and insecticide-impregnated bed nets are used for malaria control in pregnancy.Chloroquine is administered within the ANC package at health facilities in Ghana. However, many pregnant women in rural,low-income communities do not report for ANC or report late thereby increasing their risk of morbidity and mortality. Reasons for this include inaccessibility and high cost. As the gap between urban and rural health care and socioeconomic circumstances increase, malaria control remains the major challenge of the health sector. A facility-based intervention alone is not sufficient to have a significant or sustained impact on malaria control in pregnancy. Alternative strategies are needed for the delivery of malaria interventions to pregnant women in rural areas in Ghana. The overall objective of this study is to develop alternative strategies for community involvement for delivery of malaria interventions to pregnant women in rural Ghana. The project will be conducted in the Afigya Sekyere district in the Ashanti Region of Ghana. Interviews and focus group discussions will be conducted with pregnant women and community members focusing on local knowledge on control of malaria in pregnancy and factors influencing utilization of antenatal services. Women in their first and second pregnancies who are permanently resident in the study area will be included in the study using IPT with sulphadoxine-pyrimethamine (SP). The study population will be randomized to:Group 1 will receive clinic-supervised IPT-SP and daily folate/iron supplementation and Group 2 will access IPT-SP with daily folate/iron supplementation from trained traditional birth attendants (TBA). Midwives and TBAs will be trained in preparing thick blood smears and placenta biopsies for parasitological examination. Parasitaemia and Hb will be measured at entry and at delivery and fever episodes during pregnancy will be recorded. Study participants will be followed for adverse reactions within a week after drug administration. The effectiveness of community-based IPT for the control of malaria in pregnancy will be determined. The endpoints of the study will be birth weight, maternal anaemia, fever episodes and prevalence of peripheral and placental parasitaemia in the groups.
The purpose of this study to determine whether Aquatabs, a water treatment tablet, reduces diarrheal diseases in a peri-urban population of Tamale, Ghana.
Main objectives: To evaluate the impact of weekly vitamin A supplementation (VAS) to women of reproductive age (15-45 years) on maternal mortality in rural Ghana, and to compare this with the impact on overall mortality. Hypotheses: 1. Weekly supplementation with vitamin A (7000 µg retinol equivalent [RE]) to reproductive age women will reduce maternal deaths by 33%. 2. This impact will be achieved by reductions in both pregnancy-related and non-pregnancy-related deaths. 3. There will be a reduction in non-maternal deaths, similar in size to that in maternal non-pregnancy related deaths. Outcome measures: Maternal mortality rate, and overall mortality rate. Deaths will be identified through monthly demographic surveillance, and classified as maternal (pregnancy-related, non-pregnancy-related) or non-maternal using verbal autopsies.
The purpose of this study is to assess the effectiveness of Intermittent Preventive Treatment in Infants (IPTi) with Sulfadoxine-Pyrimethamine to reduce the numbers of malaria attacks, episodes of anemia, and the overall morbidity and mortality
Tuberculosis (TB) is spread by airborne transmission from adults with active contiguous TB to children, especially those living in the same household. Once children are exposed and infected they are at very high risk to develop active TB - which can be lethal if not detected and treated promptly. This makes it very important to detect TB infection as soon as possible, and treat this while it is still latent or dormant. Current therapy for latent TB infection is 9 months of Isoniazid; this is very effective if taken properly but because treatment is so long many children do not finish this. Four months of Rifampin is a recommended alternative. In adults this has been shown to be safer with much higher completion rates. However the effectiveness of this treatment is unclear, and is being studied in an ongoing study. The investigators plan to compare the safety as well as the acceptability and effectiveness of 4 months Rifampin with 9 months Isoniazid (standard treatment) in children in several sites in Canada and other countries. It is hypothesized that among children at high risk for development of active TB, intolerance/adverse events will not be worse (non-inferiority), among those randomized to 4RIF compared to those randomized to 9INH. In addition completion of latent tuberculosis infection (LTBI) therapy will be significantly greater (superiority), and subsequent rates of active TB will not be significantly higher (non-inferiority) in children taking 4RIF.
Herpes virus type 2 (HSV-2) infection - as a cofactor of human immunodeficiency virus (HIV) transmission - can be targeted by anti-herpetic specific drugs, either as a continuous prophylactic treatment during its asymptomatic shedding phase, or as an episodic treatment during clinically-apparent genital ulcerations. The main objective of this trial will be to demonstrate that acyclovir treatment given during clinical episodes (primary infection or recurrences) can reduce genital shedding of HIV, thereby contributing to a reduction of HIV infectiousness of dually infected individuals (HIV+/HSV+).
In areas of stable transmission, pregnant women, especially during the first and second pregnancies, have an increased susceptibility to Plasmodium falciparum malaria, malaria-related anaemia and an increased risk of having low birthweight babies. Intermittent Preventive Treatment in pregnancy(IPTp) with sulphadoxine-pyrimethamine has been shown to be effective in reducing the effects of malaria in pregnancy. This has mainly been in areas of perennial transmission and there is a need to study this effect in intense seasonal transmission settings. The emergence and spread of resistance to SP is likely to undermine its useful lifespan and it is important that other antimalarials that are safe and effective are identified for use in IPTp. The options are however limited. Amodiaquine has been shown to be effective in treatment of clinical cases of malaria, even in areas where chloroquine resistance is prevalent, and its combination with SP has been associated with favourable results. Both are affordable. However, there is limited data on their use in pregnancy. This study aims to assess the efficacy of SP in an area of intense seasonal transmission, and evaluate the safety and efficacy of amodiaquine and a combination of sulphadoxine-pyrimethamine and amodiaquine as possible alternatives to SP for use as IPTp.
