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.
Background: Worldwide, injuries from trauma represent a major public health problem. The World Health Organization (WHO) has deemed this problem as one of the most important global priorities, calling 2011-2020 the 'Decade of Action for Road Safety'. Despite this, there is little empirical data in low and middle-income countries quantifying the burden of musculoskeletal injuries. Methods: INORMUS is a global, prospective, multi-center, observational cohort study. The primary objective of the study is to determine the mortality, re-operation and infection rates of musculoskeletal trauma patients within 30 days post-hospital admission. The INORMUS study seeks to enroll 40,000 patients from low-middle income countries in Africa, Asia, and Latin America.
The aim of the study was to compare the efficacy and safety of single injection peribulbar anaesthesia against the classic double injection technique. This was a double blind randomized controlled trial involving two groups of consenting, adult Nigerian subjects with operable age-related cataract. An anaesthetic nurse who allocated the subjects to the two groups administered all the injections. The same surgeon operated on all the subjects while the principal investigator and a research assistant measured the outcome variables. All others were blinded as to subject allocation.
The vast majority of births with sickle cell disease (SCD) occur in Africa and 90% are thought to die before the age of five. Hydroxyurea (HU) is the only drug approved by the FDA for the treatment of sickle cell anemia. Although HU is used to treat small numbers of patients in Africa, cost, fear of toxicity, and lack of awareness and availability limit its use. The leukopenia that may be seen with HU raises the possibility of increased susceptibility to infection. Risk stratification - i.e., identification of patients most likely to benefit- could focus therapy and provide confidence that the risk:benefit ratio is favorable. Several clinical measures of future risk are well defined and findings on modifier genes in the US, primarily related to fetal hemoglobin (HbF), have further improved risk prediction. Whether the genetic variants predict severity in Africa is not known. The investigators have established a SCD cohort in Ibadan, Nigeria. In the first phase of this research the investigators will implement clinical risk examinations and assess the relationship between clinical characteristics (including levels of HbF) and known genetic markers. As a proxy for a birth cohort, the investigators will compare the frequency of the genetic markers in adult patients (i.e., "survivors") to children. In the second phase the investigators will randomize 40 high risk adult patients to fixed low dose HU or no HU treatment in a crossover design and monitor hematologic and physiologic parameters to document hematologic effects and safety. This work will lay the basis for a large-scale trial to document safety and efficacy.
Background: - An acquired heart disease is one that a person gets after they are born. Two of these are rheumatic heart disease (RHD) and endomyocardial fibrosis (EMF). They are found more commonly in people who live in Africa than in other places in the world. Researchers want to learn more about these diseases. They especially want to know what role genes and other factors play in them. Objective: - To identify genetic risk factors for RHD and EMF in sub-Saharan Africa. Eligibility: - Children and adults with RHD or EMF. - Healthy volunteers over age 10. Design: - Participants will come from existing study groups in Uganda and Nigeria. - Participants may be required to provide a sample of their DNA. They will do this with either a blood or saliva sample or a swab of the mouth. - Collected samples will be labeled with a code and sent to a lab in the United States for analysis. Remaining portions of participants samples will be stored for an unlimited period of time. They may be used in future studies. - Some genetic and health information from participants might be placed into one or more scientific databases. - Participant names and identifying information will be kept private. But there is a small chance someone could trace them from their genetic information.
Recent advances in genomic techniques are making possible a new wave of genetic discovery in congenital heart disease (CHD). Existing data suggests that CHD occur in Sub-Saharan Africa at frequencies similar to the rest of the world. In this application, we propose to utilize the unique advantages of Sub-Saharan Africa - a combination of the most genetically diverse populations in the world and of diminished environmental background effects (i.e. low prevalence of smoking, alcohol abuse, obesity in comparison to western countries) - to better understand the genetic basis for congenital heart disease. We will couple next generation genomic techniques with more traditional gene discovery methods to investigate CHD in two African countries: Uganda and Nigeria. The inclusion of syndromic and non-syndromic CHD observed in these populations as well as careful phenotyping (including echocardiography) will greatly enhance our potential to provide insight into the genetic architecture of CHD in African populations. To accomplish this, we plan to enroll families, in whom members have congenital heart malformations consistent with an error of early human development in our research protocol. Patients will be enrolled at the Uganda Heart Institute in Kampala, Uganda, and at the Department of Pediatrics, College of Medicine, University of Lagos, Nigeria, with the potential to include other African sites. High throughput genomic studies will be done at the NIH.

Nigeria has significant challenges in the delivery and coverage of PMTCT (Prevention of mother-to-child transmission of HIV) services. Only 30% of pregnant women living with HIV are provided anti-retroviral drugs for PMTCT. Less than 10% of HIV-exposed infants receive HIV testing for early diagnosis by age 2 months. Furthermore, an unacceptably high number of women with HIV who are enrolled in PMTCT programs do not complete them. In other words, uptake and retention in PMTCT programs in Nigeria is not adequate. Ultimately, mother-to-child transmission of HIV is high, resulting in a high number of new child HIV infections. Mentor Mothers (MMs) are women living with HIV who provide peer support to other HIV-positive women. MM programs have been incorporated into PMTCT programs in several African countries with some success, but with varying levels of MM training and program structure. The MoMent (MOther MENTor) study investigates whether highly-structured MM programs will further improve uptake and successful completion of PMTCT services (eg testing and appointments) in Nigeria. The study also evaluates the impact of structured MM programs on other outcomes, including facility deliveries, new infant HIV infections, infant survival and maternal viral suppression. Rural areas are the focus of this study because of their particularly poor performance in PMTCT coverage and outcomes.
The purpose of this study is to evaluate the clinical performance of the one-step Fyodor Urine Malaria Test (UMT), to determine its accuracy (sensitivity and specificity) for the diagnosis of Plasmodium falciparum malaria in febrile patients. A total of 1500 properly consented children and adults presenting with fever (axillary temperature ≥37.5°C) or history of fever in the last 48 hours (Group 1), 250 apparently "healthy" individuals (Control, Group 2), and 50 patients with Schistosoma hematobium and Rheumatoid arthritis (Group 3), will be recruited. Matched urine and fingerprick (capillary) blood samples will be collected and tested using the UMT and, Binax NOW® malaria rapid diagnostic test (blood test) and thick smear microscopy, respectively. The overall agreement of the UMT results to the Binax NOW analysis and thick smear microscopy will be used to establish UMT sensitivity and specificity.
This project is being undertaken to test the hypothesis that implementing a community based package of care for women with hypertensive disorders of pregnancy will result in overall improvement in maternal and neonatal outcomes. This is based on the premise that there are three main modifiable reasons why women (and their fetuses/newborns) die due to pregnancy complications: 1) delays by the woman herself in recognizing the seriousness of her condition; 2) delays in her being assessed and then transported to a center capable of providing effective and life-saving interventions; and 3) delays in the health facility in providing those interventions. The treatments for pre-eclampsia that are poorly accessed in LMIC are 1) magnesium sulfate (MgSO4) for prevention and treatment of the grand mal seizures of eclampsia; 2) oral antihypertensive medication to lower maternal BP to reduce the risk of stroke. The CLIP pilot and definitive cRCT will investigate whether the community level intervention including implementation of the CLIP package (oral antihypertensive therapy when indicated, intramuscular (i.m.) MgSO4 when indicated; and appropriate referral to an CEmOC facility when indicated) of care will reduce the incidence of all-cause maternal morbidity and mortality.
The purpose of this study is to determine whether a culturally-sensitive multipronged post-discharge intervention can significantly reduce blood pressure, enhance achievement of guideline recommended targets for risk factor control, and lower recurrent vascular events in a low-income and middle-income (LMIC). The study will have 2 Phases - a qualitative phase (Phase 1) lasting less than one year involving development of the intervention through focus group methodologies and structured interviews, and a clinical trial phase (Phase 2)lasting 3 years involving a randomized trial testing the efficacy of the intervention.
