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 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 evaluates the face validity and cultural acceptability of the Faces Pain Scale - Revised in pediatric patients treated at Mbingo Baptist Hospital, Northwest Province, Cameroon. Participants from the four major language/cultural groups evaluated at the hospital with a complaint of pain will trial the Faces Pain Scale - Revised and then undergo cognitive interviewing to assess comprehension and clinical accuracy.
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.
The purpose of this study is to assess the safety and immunogenicity of the investigational ChAd3-EBO-Z vaccine administered to approximately 3 000 adults in Africa as a single IM dose Considering the risk of exposure to Ebola and the potential (based on animal data) for the investigational ChAd3-EBO-Z vaccine to afford at least partial protection, all subjects in the study will receive the investigational ChAd3-EBO-Z vaccine. The subjects in the Group EBO-Z will receive the vaccine at Day 0 of the study, whereas the subjects in the Group Placebo/ EBO-Z will receive a placebo at Day 0 (as a control) and will receive the investigational ChAd3-EBO-Z vaccine at Month 6, provided that no safety concerns are raised. In addition, vaccinating all subjects in the study with the investigational ChAd3 EBO Z vaccine will allow an increase of the safety database of the investigational vaccine. In case the geographic range of Ebola virus Zaire (EBOV) transmission expands to encompass any of the regions where this trial is conducted, earlier administration of the investigational ChAd3-EBO-Z vaccine to the subjects in the Group Placebo/ EBO-Z will be considered in that region.
This is a four-week randomized controlled single blinded trial of subjects presenting with resistant hypertension in a specialized diabetes care unit of Cameroon. They are randomly assigned using the method of blocks to treatment with a daily 25mg of spironolactone or to routine intensification of antihypertensive regimen , all added to previous regimen with unchanged diet. Visits are scheduled at the start of the treatment, at weeks two and four following add-on therapy initiation. The primary outcome is change in office and self-measurement blood pressure recorded at each visit, and secondary outcomes are variations in serum potassium, sodium, and creatinine levels.

To estimate the study treatment SVR24 rate 2. To evaluate the clinical and biological tolerance of study treatment 3. To describe HCV kinetics under HCV treatment, and identify associated factors 4. To describe the evolution of HIV disease under HCV treatment in HVC-HIV co-infected patients 5. To describe the changes of liver fibrosis based on non-invasive tests between treatment initiation, week 24, and week 36 after treatment, and estimate its association with SVR12 or SVR24 6. To identify factors associated with SVR12 and SVR24 (including HIV status) 7. To evaluate the performance of a nanodevice for rapid diagnosis of HCV viral load and genotypying and for assessing response to treatment (SVR12 and SVR24) 8. Facilitate the detection and treatment of those infected with HCV by supporting national initiatives for access to strategies without interferon 9. To set up a HCV clinical research network across French and English-speaking African countries, able to run large-scale comparative randomized clinical trials in a near future.
According to the recent World Report on Disability, around 15% of the world population lives with a disability and 80% of people with disabilities (PWD) live in developing countries. More and more evidence show that PWD are more likely to be poor, vulnerable to physical and sexual violence, and to have less access to education. Therefore, PWD are likely to have an increased risk for HIV infection, potentially being a key population in regard to this epidemic. The vulnerability of PWD was recognized in 2007 by the United Nations Convention on the Rights of Persons with Disabilities. However, data on the extent how PWD are affected by HIV is still very limited. As a result, PWD are usually overlooked by National AIDS Control Programmes and few projects specifically targeting them have been developed. Recognizing the need for appropriate and reliable data to help protect the rights of PWD and achieve a better inclusion of disability in National AIDS Control Programmes, the Institute of Research for Development (IRD), the Institut de Formation et Recherche Demographique (IFORD) and Handicap International (HI) propose this study that aims to provide quantitative and qualitative data on the vulnerability of PWD to HIV infection in Cameroon and Burkina Faso, in order to define if this vulnerable population is also a Key Population in relation to the HIV epidemic. This study adopts a multidisciplinary approach (quantitative and qualitative methods). Quantitative data are collected only in Cameroon. Only the quantitative study is described here.
The aim of this pilot study is to assess the feasibility, efficacy and safety of Darunavir/ritonavir 800/100 mg once daily (DRV/r) monotherapy as a switch-maintenance strategy for patients receiving second-line ART at Yaoundé Central Hospital in Cameroon. HIV-infected adults receiving second-line antiretroviral therapy (ART) for ≥3 months with 2 nucleos(t)ide reverse transcriptase inhibitors (NRTIs) plus either lopinavir/ritonavir (LPV/r) or atazanavir/ritonavir (ATV/r) will undergo plasma HIV-1 RNA ("viral") load testing. Those with a viral load below 50 copies/ml (<50 cps/ml) will undergo a repeat test ideally 4-6 weeks later (allowed up to 12 weeks); if the viral load is confirmed as <50 cps/ml the patient will be invited to join the randomised phase of the study. Patients (n=150) will be randomised 1:2 to either continue the current triple ART regimen (n=50) or switch to DRV/r monotherapy (n=100). The primary end-point will be viral load suppression <400 cps/ml at week 24; secondary end-points will be viral load suppression <50 cps/ml at week 12 and week 24, safety, tolerability, and emergence of protease inhibitor (PI) drug-resistance. Patients will continue observational follow-up depending on the treatment arm they are randomized to. After week 48, patients will return to local standard of care. Pharmacokinetics (PK) and pharmacogenomics sub-study to correlate plasma concentrations of DRV to outcomes, HIV-1 drug resistance testing sub study to detect mutants archived at the time of first-line ART failure and measuring HIV DNA load will be performed, as well as a cost-effectiveness analysis will test the hypothesis that savings can be achieved by switching to DRV/r monotherapy without affecting quality of care. The primary virological objective is to evaluate efficacy in terms of the percentage of subjects who have plasma HIV-1 RNA levels <400 cps/ml after 24 weeks of follow-up following a switch to DRV/r monotherapy versus continuing triple therapy containing 2 NRTIs + LPV/r (or ATV/r) (FDA Snapshot method). Study hypothesis: we propose that maintenance therapy with DRV/r monotherapy is a feasible, effective and safe treatment option for patients receiving second-line ART in Yaoundé.
Background: Worldwide, injuries from trauma represent a major public health problem. The World Health Organization (WHO) has deemed this problem as one of the most important global priorities, calling 2011-2020 the 'Decade of Action for Road Safety'. Despite this, there is little empirical data in low and middle-income countries quantifying the burden of musculoskeletal injuries. Methods: INORMUS is a global, prospective, multi-center, observational cohort study. The primary objective of the study is to determine the mortality, re-operation and infection rates of musculoskeletal trauma patients within 30 days post-hospital admission. The INORMUS study seeks to enroll 40,000 patients from low-middle income countries in Africa, Asia, and Latin America.
Background The burden of sudden cardiac death (SCD) in Africa is unknown. Our aim is to assess the epidemiology of SCD in Africa. Methods The sub-Saharan Africa SCD study is a prospective, multicenter, community-based registry monitoring all cases of cardiac arrest occurring in victims > 15 years old. Investigators will use the definition of established SCD if an unexpected death without obvious extracardiac cause, occurred with a rapid witnessed collapse, or if unwitnessed, occurred within 1 hour after the onset of symptoms; probable SCD if an unexpected death without obvious extracardiac cause occurred within the previous 24 hours. After approval from institutional boards, Investigators will record demographic, clinical, electrocardiographic and biological variables of SCD victims (including survivors of cardiac arrest) in several sub-Saharan African cities. All deaths occurring in residents of districts of interest will be checked for past medical history, circumstances of death, and autopsy report (if possible). Investigators will also analyze the employment of resuscitation attempts during the timeframe of sudden cardiac arrest (SCA) in various patient populations throughout countries. Conclusion This study will provide comprehensive, contemporary data on the epidemiology of SCD in sub-Saharan Africa and will help in the development of strategies to prevent and manage cardiac arrest in this region of the world.
