There are about 22 clinical studies being (or have been) conducted in Niger. 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.
FEVRIER study is an observatory of hospitalizations in cardiology units in sub-Saharan Africa.
This study entails a quasi-experimental, mixed-methods (i.e., complementary quantitative and qualitative) outcome evaluation to assess the efficacy of the Reaching Married Adolescents (RMA) Interventions developed and implemented by Pathfinder International to increase contraception use and contraception use intentions among married adolescent girls ages 13-19 in three rural districts of the Dosso region of Niger. Intervention models (gender-synchronized household visits and small groups) will be tested using a randomized 4-arm outcome evaluation design; Arm 1 will receive household visits, Arm 2 will receive small groups; Arm 3 will receive household visits plus small groups, and Arm 4 will serve as the control group and will not receive any intervention. The quantitative component will consist of collecting quantitative baseline and 16-months follow-up survey data from randomly selected married adolescent girls (n=1200) and their husbands (n=1200) who are participating in each Arm of the study. Qualitative elements will include ethnography at two time points and semi-structured in-depth interviews half way through intervention implementation. A costing and cost effectiveness analysis will also be conducted to evaluate which intervention provides the largest gain in the primary outcomes for each dollar spent.
STUDY OBJECTIVE To confirm the incidence of in-hospital postoperative complications in adult surgical patients in Africa. STUDY DESIGN Seven day, African national multi-centre prospective observational cohort study of adult (≥18 years) patients undergoing surgery. Patients will be followed up for a maximum of 30 days. We will follow the original International Surgical Outcomes Study (ISOS) study design. The primary outcome is in-hospital postoperative complications in adult surgical patients in Africa. Secondary outcomes include in-hospital mortality and the relationship between postoperative complications and postoperative mortality. The intention is to present a representative sample of surgical outcomes across all African countries. This study will run between February and March 2016.
This study evaluates the effect of antibiotic prophylaxis with ciprofloxacin, given to the contacts of meningitis cases, on the overall attack rate of meningitis during an epidemic. One third of enrolled villages will receive standard care; in one-third of villages, household contacts of meningitis cases will be offered a single dose of oral ciprofloxacin; and in one-third of villages, the entire village will be offered a single dose of oral ciprofloxacin after the notification of the first case in the village.
The investigators performed two case-control studies in Niger and Senegal analysing fecal microbiota to characterize the specificity of the gut microbiota alteration associated with severe acute malnutrition (SAM).
The study is a double-blinded, randomized, placebo-controlled, trial with two groups of infants receiving vaccine or placebo to assess the efficacy and safety of BRV-PV. Three doses of BRV-PV containing ≥ Log10 5.6 FFU/Dose of each serotype G1, G2, G3, G4 and G9 will be administered at 4 week intervals between doses. The first administration will occur at 6-8 weeks of age. We hypothesize a difference in vaccine efficacy of three doses of BRV-PV vaccine vs. placebo against severe rotavirus gastroenteritis in healthy infants in Niger. Active surveillance for gastroenteritis episodes will be conducted throughout the trial. Surveillance for adverse events will be carried out among all children from the time of first vaccination and 28 days post-Dose 3. Surveillance for all serious adverse events, including intussusception and death, will be conducted on all participants until they each reach two years of age. To assess the effect of prenatal nutrition supplementation on infant immune response to the BRV-PV vaccine, study villages in the immunogenicity sub-cohort will be randomized in a 1:1:1 ratio to provide pregnant women with daily iron-folate, multiple micronutrients or a lipid-based nutrition supplement. Infants of participating women, if eligible at 6-8 weeks of age, will be randomized in a 1:1 ratio to receive three doses of vaccine or placebo and enter the main trial as part of the immunogenicity sub-cohort.
The long-term goal of this study is to more precisely define the role of mass azithromycin treatments as an intervention for reducing childhood morbidity and increasing growth, and for the potential selection of antibiotic resistance. The investigators propose a set of 3 cluster-randomized trials comparing communities randomized to oral azithromycin with those randomized to placebo. To assess the generalizability of the intervention, investigators will monitor for antibiotic resistance, which could potentially limit adoption of mass antibiotic treatments. The investigators will also assess several measures of infectious diseases. The investigators hypothesize that mass azithromycin treatments will reduce childhood morbidity and will be accompanied by an acceptable level of antibiotic resistance.
Our long-term goal is to more precisely define the role of mass azithromycin treatments as an intervention for reducing childhood mortality. We propose a single multi-site (multi-country), cluster-randomized trial comparing communities randomized to oral azithromycin with those randomized to placebo. We hypothesize that mass azithromycin treatments will reduce childhood mortality.
The general objective of the study is to answer to the question: "Is the current dose of AL less efficacious in the severely malnourished compared to the non-severely malnourished children, and is PK in cause?" We aim to assess whether the current treatment dose is adequate for children with severe acute malnutrition, and we hope results will guide further recommendations for malaria treatment in this specific population.
The objective of this study is to determine the efficacity of a community strategy for screening children 06-59 months old for Severe Acute Malnutrition (SAM) conducted by their mothers' compared with a community screening strategy conducted by Community Health Workers.
