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.
The main purpose of the study is to evaluate the efficacy and safety of the study drug known as prasugrel for the reduction of Vaso-Occlusive Crisis events in pediatric participants with sickle cell disease. The study will also investigate reduction in daily pain in children who have sickle cell disease.
The purpose of this study was to determine whether young children receiving Vitamin A and Zinc supplements will have a lower incidence of symptomatic malaria than similar children receiving vitamin A supplements alone.
This study tried to prove that children given food supplements containing vitamin A would have better liver vitamin A stores than children given food supplements without vitamin A over a 5 month period.
A randomized controlled trial was conducted to assess the effectiveness of text reminders sent to ACT users through an automated text messaging system short-message-system. Study hypothesis: text message reminders increase adherence
Efavirenz is an essential component of HIV treatment in children aged 3 years or older on anti-tuberculosis (anti-TB) treatment. However, the appropriate efavirenz dose during anti-TB treatment remains unclear. Rifampin (an anti-TB drug) increases the activity of the drug metabolizing enzymes that breakdown efavirenz, which may lead to low blood levels of efavirenz and treatment failure during cotreatment. The drug-to-drug interactions between the HIV and anti-TB drugs also vary between individuals based on genetic factors. This study will investigate the effects of anti-TB treatment, as well as drug-gene interactions on the blood concentrations of efavirenz in children with HIV and TB infections. Such data could enhance optimization of efavirenz dosage or selection of alternate regimens in some children.
A culturally-relevant, theoretically and empirically sound, patient-centered, standardized disclosure intervention that can be integrated into routine clinical pediatric HIV care has potential to prevent transmission and improve the welfare of children and their caregivers in Ghana and other resource-limited settings. Results from this project will also further an understanding of factors and processes driving pediatric HIV disclosure.The study hypothesis is that several key barriers to disclosure of HIV status can be modified and the process of disclosure promoted with an intervention approach that is grounded in a traditional Ghanaian concept.
Nevirapine is the preferred nonnucleoside reverse transcriptase inhibitor (NNRTI) for treatment of HIV in children younger than 3 years old who have tuberculosis (TB) coinfection. However, there is very limited data on the drug-drug interactions between rifampin and nevirapine in children of this age group. The purpose of this study is to determine the effect of rifampin-containing anti-TB treatment on the blood levels of nevirapine in young children with HIV and TB coinfection. Also, the study will find out whether checking the genetic makeup of a child could help to determine the appropriate dose of nevirapine in the setting of concomitant anti-TB treatment.
Tuberculosis (also known as TB) is a common infection and a major cause of death in children. Effective treatment using a combination of anti-tuberculosis (anti-TB) medications saves lives, but dosages of these medications are not well established in children. Several research studies have shown that the recommended dosages of the anti-TB medications in children do not lead to adequate blood levels to kill the bacteria in some children. This situation may lead to treatment failure and emergence of drug resistance. As a result, the world Health Organization (WHO) recently recommended increased dosages for all the TB medications in children. This study is being conducted to find out if the increased dosages of the anti-TB drugs are safe and lead to adequate drug levels in the blood of children with TB with or without HIV infection.
Background: - Breast cancer is becoming more common in Africa. A higher number of cases appear in women under age 35 than in the developed world. However, little is known about the factors that may contribute to breast cancer in Africa. Researchers want to collect information from female patients in teaching hospitals in Accra and Kumasi, Ghana and to compare this information with that obtained from healthy women in the general population. These two hospitals treat most breast cancers in Ghana. The data will provide information regarding factors that predispose to the development of breast cancer among women in Ghana. Objectives: - To identify and study breast cancer risk factors in women in Ghana. Eligibility: - Women between 18 and 74 years of age who are diagnosed with breast cancer. - Participants will come from teaching hospitals in Accra and Kumasi, Ghana. Women without breast cancer will be identified from the 2010 Ghanaian Census for comparison purposes Design: - Participants will answer questions about their health and lifestyle. - Height, weight, and waist/hip measurements will be collected. - Blood and saliva samples will be collected. - Participants will be given a collection kit to collect a stool sample. - Treatment will not be provided as part of this study.
This is a WHO-sponsored trial. Combination therapy with streptomycin and rifampicin has been the standard antibiotic treatment for M. ulcerans infection since 2004. In March 2010, a WHO Technical Advisory Group recommended that a trial be carried out to develop a fully oral treatment for the disease. Although the current treatment is effective, injection with streptomycin is a problem. Several small observational studies (published and unpublished) have shown that a fully oral treatment is promising. This WHO sponsored study will be a randomized, controlled open label non-inferiority phase II/III, multi-centre trial (1 centre in Benin and 4 centres in Ghana), with two parallel treatment groups. The ultimate goal is to search for an effective alternative treatment to the current standard WHO-recommended therapy for all forms of Buruli ulcer, which includes injections of streptomycin with inherent logistic, operational and safety disadvantages.
