There are about 351 clinical studies being (or have been) conducted in Nigeria. 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.
In the last decade, the prevalence of malaria has been escalating at an alarming rate, especially in Africa. An estimated 300 to 500 million cases each year cause 1.5 to 2.7 million deaths, more than 90% occur in children under 5 years of age in Africa (WHO 1995). Malaria is Africa's leading cause of under-five mortality (20%) and constitutes 10% of the continent's overall disease burden. It accounts for 40% of public health expenditure, 30-50% of inpatient admissions, and up to 50% of outpatient visits in areas with high malaria transmission. Antioxidant micronutrients have immunomodulatory role and may have suppressive activity.
The Millennium Villages Project involves the coordinated and simultaneous delivery of a package of proven interventions in health, agriculture, infrastructure and education. The project works in partnership with governments in 10 African countries in areas where progress towards achieving the Millennium Development Goals has been insufficient. The Project evaluation will test the following hypotheses: 1. That after 5 years of operation, villages exposed to the MVP intervention will have a lower rate of under-5 mortality and parallel gains in MDG-related secondary outcomes when compared to similar villages not receiving the intervention. 2. That the coordinated delivery a multi-sector package of health and development interventions implemented through a broad-based local partnership is feasible in a diversity of sub-Saharan African contexts, and; 3. The intervention package can be delivered at a scalable cost of $40 per person per year in the health sector and $110 per person per year in total
The purpose of this study is to compare the blood pressure lowering efficacy of a treatment regimen based on a dihydropyridine calcium-channel blocker combined with an angiotensin II type-1 receptor blocker with the recommended treatment regimen based on a low-dose thiazide diuretic combined with a beta-blocker.
The purpose of this study is: 1. To compare the response of rickets to calcium with and without vitamin D. 2. To assess whether vitamin D increases calcium absorption in calcium deficiency rickets. 3. To compare the response of children with and without rickets to orally administered vitamin D3 and vitamin D2 4. To identify mutations that influence calcium and vitamin D metabolism among families of children with rickets in Nigeria and Bangladesh. 5. To assess the functional status of the 25-hydroxylase enzyme in families possessing a 25-hydroxylase mutation.
The investigators hypothesize that following virological failure of a standard NNRTI+2N(T)RTI regimen second-line antiretroviral therapy consisting of ritonavir-boosted lopinavir and 2N(T)RTIs will offer comparable efficacy to that provided by ritonavir-boosted lopinavir and raltegravir. The study will be conducted for 96-weeks with the primary endpoint analyzed after 48-weeks. The primary endpoint is virological: a comparison of virological suppression in plasma < 200 copies/mL between the randomized arms after 48 weeks. Secondary and exploratory endpoints include virological, immunological, safety, clinical, metabolic, drug adherence, drug resistance and quality of life.
The WOMAN trial is a large pragmatic randomised double-blind, placebo controlled trial to quantify the effects of the early administration of tranexamic acid on death, hysterectomy and other relevant outcomes. 20,000 adult women, after delivery who have clinically diagnosed postpartum haemorrhage, are eligible if the responsible doctor is for any reason substantially uncertain whether or not to use an antifibrinolytic agent. Additionally, TWO nested studies will be conducted in a subset of women trial participants. The first nested study (ETAC) aims to evaluate the effect of tranexamic acid (TXA) on markers of coagulation in 400 women randomised to the WOMAN trial. The second nested study (ETAPLAT) aims to evaluate the haemostatic effect and antithrombotic effect of TXA in 128 women randomised to the WOMAN trial.
Objectives: - To find out if the chance of developing a serious illness or of getting AIDS is less if patients start taking HIV medicines at a time when their cluster-of-differentiation-4 (CD4)+ cell count is still fairly high, instead of waiting until the CD4+ count is at the level where there is good evidence for starting medicines. - To learn more about how a strategy of starting HIV medicines early might affect other aspects of care, such as the chances of developing other illnesses or resistance to HIV medicines, the frequency of doctor visits, the cost of medical care, and general health and satisfaction.
Background: - Cervical cancer is caused by persistent infection of the lining of the cervix with some kinds of human papillomaviruses (HPV). These HPV infections are distantly related to the viruses that cause warts on the skin. Like common wart viruses, most women who have cervical infections with HPV resolve the infections within 2 years without any need for treatment. Cervical infections that do not go away may cause disease that can turn into cancer after many years. - Only one study has been done in Nigeria to learn how many women have HPV infection. The results of the study differed from most other studies in the world because older women were much more likely to be infected. This study with learn whether the results found in the previous study are true in Irun also, the site of the current study. Objectives: - To examine the age distribution of HPV infection and relationship to cancer of the cervix among Nigerian women. - To understand how different screening methods, including HPV testing, could best reduce the risk of cervical cancer in Nigerian women. Eligibility: - Women residing in Irun, Nigeria, who are 15 years of age or older. Design: - Participants complete a brief questionnaire related to demographics, household and living conditions and a longer survey with questions related to reproductive history, family history, illnesses, stressful life events and sexual history (U. of Michigan collaboration). - Participants have a cervical examination, HPV test, Pap test and blood test. - Women whose tests show they are infected with HPV or have cervical disease will do the following: - see a doctor and have cervical biopsies of all white abnormal areas (removal of a small tissue sample from the cervix) - have photographs of the cervix taken - have a cervical scraping for a new kind of HPV test. - Some women with normal test results are also asked to see a doctor to check the validity of the testing - Women with cervical disease receive treatment by a specialist and remain in the program until treatment is successfully completed or a final diagnosis is reached. - Participants may be contacted for followup up to 5 years after the final diagnosis is made.
This study will assess the safety and efficacy of artemether-lumefantrine tablets (6-dose regimen) in African infants / children with acute uncomplicated falciparum malaria.
The purpose of this study is to assess the immunogenicity in terms of antibody response and the safety/reactogenicity in terms of solicited and unsolicited symptoms and serious adverse events following primary vaccination of African Sub-Saharan infants with pneumococcal conjugate vaccine GSK 1024850A co-administered with a diphtheria, tetanus, whole cell pertussis (DTPw)-combined vaccine and oral polio vaccine in children during the first 4 months of life.
