NCT ID: NCT02486523 Completed - Severe Malnutrition Clinical Trials

Benefits of a Household WASH Package to Community-based Management of Acute Malnutrition (CMAM) Program, Chad

Start date: April 2015
Phase: N/A
Study type: Interventional

The objective of the research is to assess the effectiveness of adding a Household WASH component to the standard outpatient treatment of severe acute malnutrition. Study design: cluster-randomized controlled trial comparing two interventions: 1. Control group: outpatient management of children diagnosed for severe acute malnutrition only 2. Intervention group: outpatient management of children diagnosed for severe acute malnutrition + "household WASH package" 2000 children, aged between 6 and 59 months, admitted to 20 OTP (Outpatient Therapeutic Program) centers for SAM will be included into the study and followed for 8 months (2 months of treatment, and 6 months after successful discharge).

NCT ID: NCT02085044 Completed - Malnutrition Clinical Trials

Non Randomized Controlled Intervention Study Comparing Two Interventions of Nutritional Supplement on Malnutrition, Health and Mortality

Start date: February 2012
Phase: Phase 4
Study type: Interventional

The hypothesis for the study is that 12 months of a Ready-To-Use Supplementary Food (RUSF) distributions have a greater impact on children's health than the standard RUSF distributions during the hunger gap period (june to september). We estimated that the 12 month RUSF will decrease the incidence of severe acute malnutrition by 33% compared to an administration only during the hunger gap period (4 month a year).

NCT ID: NCT01559597 Completed - Tetanus Clinical Trials

Comparative Study of Two Tetanus Toxoid Vaccination Strategies: Cold Chain Versus Controlled Temperature Chain

Start date: November 2012
Phase: N/A
Study type: Interventional

The purpose of this study is to determine the effectiveness, safety and feasibility of a tetanus toxoid (TT) vaccination strategy relying on the maintenance of vaccines in a controlled temperature chain (CTC). The CTC is defined as the storage and transport of vaccines within a temperature range appropriate to the heat stability profile of TT vaccine. In this study vaccines are transported and stored in the cold chain up to district level. From district to beneficiary level vaccines are exposed to ambient temperatures during a limited period of time. In an initial phase, the stability of 3 lots of TT vaccine kept in CTC is determined. For this, the potency, safety, pH and adsorption of vaccines maintained in CTC will be tested in the laboratory and compared to vaccines that have been maintained in cold chain. If all parameters (i.e. potency, safety, pH and adsorption) are above WHO specifications the strategy in CTC will be used. Only if the laboratory results are adequate, villages will be assigned to one of the vaccination strategies. All women between 14 to 49 years of age in the selected villages who fulfill the inclusion criteria will be invited to participate. In order to determine the baseline anti-tetanus protection, TT vaccination history will be collected from all participants using a standardized questionnaire. Women who have already received at least 2 doses of TT vaccine will be excluded from the study. Moreover, blood will be collected from all participants to later verify in laboratory the baseline protection. A first dose of TT vaccine will be given according to the assigned strategy (CTC or cold chain). Four weeks after the 1st vaccination, a second TT vaccine will be given using the same strategy employed for the first dose. Finally, four weeks after the second dose, a blood sample will be collected from all participants who received two doses of vaccine. The serological responses will be compared in the group that received two doses of TT vaccine maintained in cold chain ant the group that received two doses of vaccine maintained in CTC.

NCT ID: NCT01154595 Completed - Malnutrition Clinical Trials

Effectiveness of a Ready-to-Use-Food (RUF) Supplement to Prevent Acute Child Malnutrition

Start date: June 2010
Phase: Phase 4
Study type: Interventional

The overall objective of this project is to assess the effectiveness and cost-effectiveness of RUF (ready-to-Use Food, Plumpy Doz(r)) to prevent moderate acute malnutrition in children aged 6-36 months if embedded in a program of conditional household food assistance.

NCT ID: NCT01119482 Completed - Meningitis Clinical Trials

Study on the Impact of Vaccination With a Conjugate Vaccine on Meningococcal Carriage

Start date: May 2010
Phase: Phase 4
Study type: Interventional

Meningococcal disease occurs throughout the world but attack rates in the Sahelian and sub-Sahelian regions of Africa - the African meningitis belt - are many times higher than those seen in any other part of the world. During 2009, over 70,000 meningitis cases and 3,200 deaths were reported in Nigeria, Niger, and Chad alone. In 2001, a public private partnership between WHO and PATH was created, the Meningitis Vaccine Project (MVP). The MVP set out to develop an affordable meningococcal serogroup A conjugate vaccine (MenAfriVacâ„¢) for use in the African meningitis belt. This was successfully achieved, and the new vaccine, produced by the Serum Institute of India (SII), was granted a licence in 2009 for international export. The vaccine dossier was submitted to WHO for prequalification at the beginning of 2010. Introduction through mass vaccination is planned in three African Meningitis belt countries in 2010 (Burkina Faso, Mali and Niger). The implementation of MenAfriVac will be the responsibility of the local Ministry of Health, with the support of the World Health Organization. It is anticipated that this vaccine will be deployed in other countries of the meningitis belt in 2011. This vaccine should provide high levels of direct protection to immunised individuals but, as for serogroup C conjugate vaccines in the United Kingdom, a greater public health impact will be achieved if carriage and transmission of the infection are also prevented. The London School of Hygiene & Tropical Medicine (LSTHM) is coordinating the African Meningococcal Carriage Consortium (MenAfriCar). One of the primary objectives of the MenAfriCar project is to evaluate the impact of the new conjugate vaccine on meningococcal carriage and transmission of serogroup A meningococci in Mali, Niger and Chad. A community-based prospective, pre- and post intervention, observational study will be conducted. MenAfriCar will also help to develop research capacity in the participating African countries.
