There are about 141 clinical studies being (or have been) conducted in Cameroon. 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 ultimate aim of this registry is to collect precise information concerning the children coming to oncology units working with the French African Oncology Group. This data will help to plan and provide correct pediatric oncology treatment and care for this population. Collecting the data will give much needed information on numbers, stage, treatment and outcome. The register will give data for local and national health authorities in planning pediatric cancer programs.
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.
The CADRE study is a multinational observational cohort of patients with sickle-cell disease (SCD) in five west and central sub-Saharan African countries. The aim of this project is to describe the incidence and assess the predictive factors of SCD-related micro- and macro-vascular complications in sub-Saharan Africa.
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 purpose of this study is to determine if the use of ketamine, sniffed in the nose, is a safe and effective way to help reduce pain in pediatric sickle cell patients with pain crises in resource-limited settings.
This study aims to perform a comprehensive neuro-cognitive evaluation of the 4-7 year old children from the Pediacam cohort (ANRS 12140 /12225, NCT02043418). It is expected thereby to provide complementary information to the trials CHER and PREDICT on the long term development of (1) HIV-infected children according to age at ARV initiation and (2) HIV exposed but not infected children, all compared with the control group of children uninfected, unexposed to HIV.
Background The burden of sudden death (SD) in sub-Saharan Africa is unknown. The aim is to assess the incidence, etiology and patient characteristics of SD in a sub-Saharan country. Methods The Douala-SD study is a prospective, multicenter, community-based registry monitoring all cases of SD occurring in index areas of Douala city. Investigators will use the definition of SD as natural death occurring within 24h at the onset of symptoms. Demographic, clinical, electrocardiographic and biological variables (when available) of victims will be recorded. All deaths occurring in residents of health areas of interest will be checked for past medical history, circumstances of death, and autopsy (if possible). Conclusion This maiden Douala-SD study will provide comprehensive, contemporary data on the epidemiology of SD in a sub-Saharan African country and will help in the development of strategies to prevent and manage SD in Africa.
Significant progress has been made in the treatment of Wilms tumor in high income countries, where survival is now around 85% - 90%. Survival in low income countries is much lower; specific challenges include late presentation, malnutrition, less intense supportive care facilities and failure to complete treatment. A comprehensive treatment guideline was introduced in Malawi in 2006 which included nutritional support and social support to enable parents to complete treatment. Survival has increased to around 50%; 95% of children completed their treatment. A multi-disciplinary group of African clinicians and 'state of the art' experts produced a consensus treatment guideline for children with Wilms tumor in sub-Saharan Africa. This guideline will be implemented as a multi-center prospective clinical trial in 2014 in six - eight institutes, expecting about 200 new patients per year. The hypothesis is that 2 year event free survival will be 50%, with <10% failure to complete treatment and <10% treatment related mortality. Other research questions include efficacy and toxicity of preoperative chemotherapy and the comparison of surgical staging, local pathology and central review pathology in stratifying postoperative chemotherapy.
The primary objective of the study is to compare the tolerance and safety between a low-dose Zidovudine (AZT) containing regimen (200 mg BID) and a standard dosage (300 mg BID) in HIV patients initiating a first line antiretroviral therapy. The investigators expect that the low-dose regimen will show improved tolerability and safety compared to the standard dosage, with significant reduction in number of patients experiencing a new grade 1 to 4 anaemia or increasing their anaemia grade during the first 6 months of treatment. The secondary objectives of the study is to compare the efficacy of the two dosing regimen, as measured by classical clinical and biological markers: the number of new AIDS defining illness, the mortality rate, the proportion of patients achieving virological success and the mean CD4 cell count increase from baseline.
