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.
The purpose of this study is to determine if in a rural setting of Ondo State, Nigeria, a customized automated telephone and email immunization reminder system will be feasible, acceptable, and significantly improve immunization utilization rates.
The prevalence of iron deficiency anemia is a wide spread problem in Africa and iron fortification can be an effective strategy to decrease this. In the current study adding different levels of a stabilizer to iron fortified cubes and it's effect on iron bioavailability from these cubes will be studied in the context of a Nigerian meal in women. 24 Female subjects with low serum ferritin levels will be included in the study. The study will last 64 days and subjects will be asked to consume a breakfast and lunch prepared with a bouillon cube with isotope labeled iron during 3 periods of 5 consecutive days. The absorption of iron will be evaluated after every period and compared between the cubes.
Helicobacter pylori is a common bacterial infection. It can lead to severe stomach problems, including stomach cancer. Researchers want to look at samples of the bacteria. These H. pylori strains will be taken from chronically infected people. They want to identify the genetic and epigenetic differences in H. pylori strains. This could help predict which people who get infected with the bacteria will get stomach cancer. This could lead to the cancer being detected earlier. It could also mean less people get stomach cancer. Objectives: To study genetic variations of H. pylori strains based on samples from chronically infected people. To identify the features of strains that might lead to severe stomach problems or stomach cancer. Eligibility: People ages 30-70 years who need an upper endoscopy or who were recently diagnosed with stomach cancer Design: Participants will be screened by the doctor who does their procedure and a study nurse. Participants who have endoscopy will have ~6 biopsies removed. These are tissue samples. They are about the size of a grain of rice. Participants will allow the study team to access reports from their stomach exam. Participants with stomach cancer will donate some of the tissue that will be removed during their clinical care. They will allow the study team to access reports of their surgery. They will also allow them to access the microscope slides of their stomach.
A multi-centre, randomized, placebo controlled, trial. Participants at high-risk for vascular events from the network of INTER- CHF will be randomized to inactivated influenza vaccine or placebo and followed prospectively over three influenza seasons. 5,000 participants will be enrolled prior to influenza season, randomized to either influenza vaccine or saline placebo, either of which they will receive annually for three years and then followed over each of the influenza seasons.
The creole study is a A Multi-centre, multinational, randomised single-blind, parallel group, three-armed superiority trial which is aimed at comparing the efficacy of three "free" combinations of two anti-hypertensive agents on 24 hour ambulatory systolic blood pressure (ASBP) in black African hypertensive patients.
An investigator initiated and conducted, multicentre, international, double-blinded, placebo-controlled, parallel-group, randomised controlled trial to determine the effect of more intensive blood pressure control provided by a fixed low-dose combination blood pressure lowering pill ("Triple Pill") strategy on top of standard of care, on time to first occurrence of recurrent stroke in patients with a history of stroke due to intracerebral haemorrhage.
The overall goal of the proposed study is to determine the effectiveness of hydroxyurea therapy for secondary stroke prevention and prevention of other neurological events in children with SCA with an acute overt stroke.
Girls for Health (G4H) will promote the economic empowerment, agency, and voice of rural adolescent girls by supporting their transition from secondary school to tertiary training in midwifery, medicine, nursing and other health careers, and in so doing, will address the acute shortage of female health workers in rural Northern Nigeria. G4H will integrate proven girls' education strategies with innovative vocational interventions to build 1350 girls' career aspirations and academic achievement and will significantly increase the number of rural girls entering health training institutions (HTI) in four northern states. The program will include: 1) a bridge program offering accelerated academic instruction in science, math and English; 2) vocational counseling and practicums at local health facilities; 3) safe spaces to enhance critical life skills; 4) four month science immersion courses for girls accepted for admission to a health training institution; and 5) HTI capacity building to cultivate a rural female-friendly learning environment. G4H will work towards sustainability from the start by using existing secondary school and HTI infrastructure, and feeding into government rural health worker employment schemes. G4H will be evaluated using a rigorous cluster randomized controlled trial design, randomizing at the school level to assess its impact on key outcomes of interest that include rural girls' secondary school graduation and subsequent HTI enrollment, retention and completion, as well as delayed marriage and improved agency and voice. Process monitoring and costing analysis will be conducted to support quality implementation and dissemination efforts. The design will ensure that high quality evidence is available to guide the field regarding the effectiveness and costing of in-school bridge programming in broadening rural girls' participation in education and career opportunities in the context of low resource settings characterized by low rates of female participation in education and income generation.
The study comprises an open-label randomized controlled trial investigating the efficacy of consuming a daily ration of pro-vitamin A biofortified cassava on vitamin A status of Nigerian children, aged 3-4 years old (n=200).
At present, much of sub-Saharan Africa, including Nigeria and other resource-limited countries, are without ready access to CPT, due to factors including the lack of PT devices, which are expensive and require consistent electric power to operate. NHB is a significant cause of neonatal morbidity and mortality, but preventable when appropriate treatment is initiated. We have shown that FS-PT is safe and efficacious for the treatment of mild-moderate NHB. The major goal of this study is to demonstrate that FS-PT is efficacious for the treatment of significant/severe NHB, generally defined as TB of ≥12-14mg/dL (but more specially as defined as needing phototherapy per American Academy of Pediatric 2004 guidelines). This arm was done at 1 site in Nigeria (in Ogbomoso). The rationale for conducting the study is that in Nigeria, and other countries that cannot afford effective commercial light devices and/or have no reliable electric power to operate them, filtered sunlight phototherapy might offer a safe and effective treatment for neonatal jaundice.
