NCT ID: NCT03303963 Recruiting - Clinical trials for Tuberculosis, Multidrug-Resistant

DIAgnostics for Multidrug Resistant Tuberculosis in Africa

DIAMA
Start date: May 4, 2017
Phase: N/A
Study type: Observational

Recent advances in molecular diagnostics of tuberculosis, especially the GeneXpert Mycobacterium tuberculosis/Rifampicin test have reduced the time to diagnose Rifampicin Resistant Tuberculosis (RR-TB) but only rifampicin resistance is diagnosed, leading to presumptive diagnosis of resistance to isoniazid and maybe other drugs. Thus in low and middle income countries, most drug sensitivity testing relies on phenotypic drug resistance testing, which takes up to 4 months. In addition, currently, culture on monthly sputum samples is recommended by the World Health Organization for follow-up of Rifampicin Resistant Tuberculosis patients under treatment. Unfortunately, culture is often not locally available and samples need to be transported from field to culture laboratories. The associated transport delays lead to high rates of contamination and false negative culture, particularly in laboratories in low resource settings. Many gaps for the diagnosis and management of RR-TB patients still need to be addressed and the DIAMA project (DIAgnostics for Multidrug resistant tuberculosis in Africa) study aims to address some of them.

NCT ID: NCT03225794 Recruiting - Clinical trials for Simian Foamy Virus Infection (Disorder)

Simian Foamy Virus Transmission to Humans

Start date: November 1, 2010
Phase: N/A
Study type: Observational

About three quarters of the viral agents that have emerged recently in humans are considered to originate from other animals. These viruses have often evolved and spread into the human population through various mechanisms after the initial contact that resulted in interspecies transmission. However, knowledge of the initial stages of the emergence of viruses and associated diseases is still limited in many cases. Microbiological monitoring in populations at risk of transmission would provide insights into the initiation and early stages of the emergence process. Nonhuman primates (NHPs) share many genetic, physiological, and microbiological features with humans, and are potential sources of many infectious agents. This has been demonstrated for several simian retroviruses. HIV-1 and 2 are believed to have originated from chimpanzee and mangabey viruses, respectively, found in Central and West Africa. The current distribution of the various molecular subtypes of the HTLV-1 oncogenic retrovirus in Africa is mainly the result of numerous instances of interspecies transmission of STLV-1from NHP species in the distant past. Foamy viruses belong to the Retrovidae family and the Spumavirus genus. They are complex exogenous retroviruses and are very common in many animal species, including primates, cats, cattle, and horses, in which they cause persistent infections. The first aim of the work is to study the epidemiological and molecular aspects of the transmission of foamy viruses from monkeys to humans in populations at risk, such as the inhabitants (especially hunters) in the villages of the dense forests of southern Cameroon. It is an area in which NHPs are still very common, with a great diversity of species. The investigators have already shown that the prevalence of foamy viruses is very high in these monkeys and great apes (gorillas and chimpanzees). Contact between these monkeys and the villagers is very frequent, mainly during hunting. The second aim of the project is to study the clinical and biological features of infected people and investigate intrafamilial transmission from infected index cases.

NCT ID: NCT03195036 Recruiting - Clinical trials for Early Childhood Development in HIV-Exposed Children

Evaluation of an Early Childhood Development Intervention for HIV-Exposed Children in Cameroon

Start date: April 17, 2017
Phase: N/A
Study type: Interventional

There is substantial evidence that early childhood development (ECD) programming can improve child health and development outcomes. An important component of ECD programming is supporting positive parenting and early stimulation practices. While many parents could benefit from such programming, mothers that are HIV-infected may particularly benefit given the higher risks of poorer child development among HIV-exposed children. Catholic Relief Services (CRS) in Cameroon is implementing the Key Interventions to Develop Systems and Services (KIDSS) ECD program for HIV-exposed children. The program will include home-, facility-, and community-based components. This impact evaluation will ascertain to what extent the KIDSS home-based component of the ECD model affects attainment of age-appropriate developmental milestones (measured by the Ages and Stages Questionnaire 3 (ASQ-3)) in HIV-exposed children in Cameroon. The study design is a cluster-randomized controlled trial with a cohort of 200 mother/child dyads across 10 study clinics. HIV+ mothers will be recruited during pregnancy and their children will be followed up until 18 months of age. The intervention group will receive regular home-based ECD services focused on positive parenting and early stimulation as well as exposure to facility- and community-based ECD programming. The control group will only have exposure to the facility- and community-based ECD programming. Randomization occurs at the clinic (cluster) level.

NCT ID: NCT03114137 Recruiting - Sickle Cell Disease Clinical Trials

NCT ID: NCT03044899 Completed - Surgery Clinical Trials

African Surgical Outcomes Study (ASOS)

ASOS
Start date: February 1, 2016
Phase: N/A
Study type: Observational [Patient Registry]

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.

NCT ID: NCT03024762 Active, not recruiting - Clinical trials for Pediatric HIV Infection

Active Search for Pediatric HIV/AIDS (ASPA)

ASPA
Start date: July 2015
Phase: N/A
Study type: Interventional

The Active Search for Pediatric HIV/AIDS (ASPA) aims at assessing the acceptability, feasibility and effectiveness of the targeted provider-initiated-testing and counseling (tPITC) in comparison with the blanket provider-initiated-testing and counseling (bPITC) among children and adolescents in Cameroon. The new knowledge generated will inform programming of more suitable strategies to identify HIV-infected children and adolescents and this will contribute to reducing the current global gap in HIV treatment among this subpopulation group.
