There are about 10 clinical studies being (or have been) conducted in Nicaragua. 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 overall objective of this multisite, multicountry Zika in Infants and Pregnancy (ZIP) study is to assess the strength of the association between Zika virus infection (ZIKV) during pregnancy and adverse maternal/fetal outcomes and the risk of vertical transmission. The study will prospectively enroll a cohort of pregnant women during the first trimester of pregnancy and follow them through their pregnancy to identify for clinical evidence of acute ZIKV, while controlling for potential confounders. Outcomes in the women, the developing fetus, and infants will be assessed. All protocol-specified data will be recorded and entered in a central data management system for the purposes of analysis of composite data from the study.
The purpose of this study is to evaluate the efficacy of 2 doses of Tetravalent Dengue Vaccine Candidate (TDV) in preventing symptomatic dengue fever of any severity and due to any of the four dengue virus serotypes in 4 to 16 year old participants.
The purpose is to assess feasibility of rice bran consumption in weaning children and collect pilot data on gut microbiome and metabolome modulation with rice bran intake for diarrheal prevention.
Adolescents in Latin America are at major risk for unwanted pregnancies leading to unsafe abortions and maternal health risks. Mostly, adolescent health programmes tend to focus on unidirectional interventions aiming at a single determinant of adolescents´ sexual and reproductive health. However, evidence exists that a complex health problem should be addressed by an equally nuanced and multipronged response. Knowledge is lacking on how to develop a comprehensive approach to promote adolescents' sexual health. The CERCA study will conduct an implementation based on the hypothesis that a comprehensive strategy of community-embedded interventions helps to improve the sexual health of adolescents. We will test this hypothesis and describe the development, implementation and testing of interventions in three Latin American cities: Cochabamba (Bolivia), Cuenca (Ecuador) and Managua (Nicaragua). The research methodology has been designed based on the methodological frameworks of action research, community based participatory research and intervention mapping. The interventions are complex addressing different target groups (adolescents, parents, authorities and health providers) and focussing on various behaviours that are related to communication about sexuality, information seeking, access to health care and safe sexual intercourse. For the evaluation of effectiveness a randomised and non-randomised controlled study was developed for respectively Managua and the two other cities. Furthermore a process evaluation is conducted. This research will result in a framework that will contribute to the planning of interventions that are effective and responsive to adolescents' sexual health needs.
The purpose of this study is to compare the effectiveness of three different antibiotic regimens against Helicobacter pylori (H. pylori).
The primary objective is to determine if continuous COC use leads to higher continuation rates over 12 months of follow up than use of the standard 28-day COC regimen.
This booster study will assess the immunogenicity, reactogenicity and safety of a booster dose of GSK Biologicals' DTPw-HBV/Hib Kft. vaccine versus DTPw-HBV/Hib vaccine, in healthy children, 18 to 24 months of age, who received the same vaccine for primary vaccination. Prior to the booster dose, this study will also assess the persistence of antibodies to the vaccine antigen components administered in the primary vaccination course. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
A bacterium called Group A Steptoccoccus or "strep" is commonly found in the nose and throat of healthy adults and children and can cause a variety of illnesses. If this bacterium infects another part of the body one or more times, children may get Rheumatic heart disease (RHD). The purpose of this community based study is to see how many children between 5-15 years of age have RHD in Leon, Nicaragua. The study will also help to determine if the usual methods of detecting this disease are working. Researchers hope that this study will help to develop vaccines that may prevent "strep" infections to Nicaragua and other parts of the world. About 3,600 children will take part in the study. The children will participate for a minimum of 1 day and have a 6 month follow-up visit if they are identified as possible or probable RHD cases. Study procedures will include clinical exams and echocardiograms to determine the presence of RHD.
The purpose of this study is to determine the epidemiology of throat isolates of group A streptococci among 3-15 year-old children with pharyngitis (sore throat) living in Leon, Nicaragua.
The main objectives of this study are: 1) In a subset (N = 20 000), to determine vaccine efficacy against severe rotavirus (RV) gastroenteritis (GE) during the period starting from 2 weeks after Dose 2 until one year of age. 2) In all subjects (N = 60 000), to determine the safety of GSK Biologicals' HRV vaccine with respect to definite intussusception (IS) within 31 days (Day 0-Day 30) after each HRV vaccine dose.
