There are about 138 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.
This is a prospective observational study enrolling People Living with HIV (PLHIV) who are on a Dolutegravir-based AntiRetroviral Treatment (ART) regimen and experiencing virologic failure. Virologic failure is defined as two consecutive viral load measurements of >1000 copies/mL of blood. The main aim of the study is to identify the drug-resistance mutations in the viral genome that are associated with this failure. To achieve this goal, patients fulfilling the eligibility criteria will be invited for a single study visit for the collection of blood. The extracted HIV virus will be sequenced through whole genome sequencing methods to identify the drug-resistance mutations. The study is conducted in 15-20 countries within six regions of the IeDEA cohort (International epidemiology Databases to Evaluate AIDS).
Non-communicable diseases (NCDs) such as diabetes are increasing in countries where malaria transmission is common. This study aims to investigate the relationship between NCDs and parasitic infections in Cameroon. The investigators will assess the risk of malaria, as well as other parasitic diseases, in a prospectively followed group of adults with diabetes, compared with those without diabetes. Malaria parasites and intestinal worms will be tested using blood and stool collected at four time points during a one-year follow-up. In addition, this project will investigate how natural protection against malaria is affected by diabetes and other risk factors for heart diseases.
Cervical cancer is a public health problem in Cameroon.In 2020, the country had a crude incidence of 20.2 per 100 000 women for an incidence to mortality ratio of 0.65. As for now, the country does not have a national screening program to combat the disease. Only 6% of cameroonian women have once been screened for cervical cancer. In order to increase screening uptake so as to reach 70% recommended by the World Health Organization (WHO), a home-based cervical cancer screening approach is proposed. The objective of our study is to compare two recruitment strategies for cervical cancer screening in rural Cameroon.
The Plus Project will assess the impact, operational feasibility, efficacy, effectiveness, and cost-effectiveness of PMC. Specifically, the impact evaluation will involve monitoring a passive cohort of all children in the study area reporting all doses of SP received and the number of confirmed cases of malaria and anaemia, as well as a prospective active cohort of children who will have seven home visits over an 18-month period. The total number of participants is expected to be approximately 2,080 children in the areas served by 35 health centres in Cameroon. The results of this study will allow direct evaluation of the protective efficacy of PMC on malaria incidence, severe anaemia, and malaria mortality.
The aim of this study is to investigate if diabetes, obesity and metabolic syndrome affects disease presentation and severity of malaria in adults in a hospital setting in Cameroon.
Cervical cancer is the leading cause of cancer death among women in sub-Saharan Africa, despite the existence of effective prevention and screening methods. Because vaccination rates against human papillomavirus (causing nearly all cervical cancers) are still insufficient in some low-resource countries, early detection and treatment of cervical lesions at risk of progressing to cancer are crucial components of cervical cancer control. Therefore, it is essential to find the most reliable and appropriate screening strategy in the context of low-resource countries in order to identify women in need of treatment and thus prevent the development of cervical cancer. The objective of our study is to compare two different methods of cervical cancer screening adapted to low-resource settings, in two study centers in Cameroon.
The aim of this study is to assess knowledge, beliefs and attitudes of parents to young girls aged 9 to 14 years about HPV vaccines within some rural communities in the North West Region of Cameroon served by three hospitals in that area. To do this, we will conduct in-depth qualitative interviews with purposively sampled parents of girls aged 9 to 14 years, some of whom received HPV vaccine and some of whom did not. Interviews will continue until thematic saturation is reached (We anticipate a total 40 interviews). Data analysis will be done concurrently with interviews using thematic analysis.
The overall objective of this research is to understand the PHC landscape in conflict-affected settings including choice of PHC delivery models and quality interventions used by humanitarian organisations
Although Plasmodium vivax (P. vivax), one of the five malaria species causing parasites, has the widest geographical distribution, it is rare in sub-Saharan Africa due to the absence of a red blood cell receptor (Duffy antigen) in black Africans. Duffy-negative individuals are, for the most part, therefore refractory to P. vivax infection and the Duffy-negative phenotype is found at highest frequencies in Africa, whereas it is relatively rare elsewhere. P. vivax has however, been observed as single infections in up to 5% of Duffy-negative febrile patients in one health facility in Dschang, a region of low malaria transmission in Western highlands of Cameroon. Whereas in the littoral South West and Southern forest of Cameroon characterised by high malaria transmission, areas, there are contrasting molecular evidence of human P. vivax infection. While important, the significance is limited from an epidemiological point of view, concerning the source, transmission, distribution range of P. vivax. There is thus a challenge in the true estimation of malaria burden, as well as the attributable parasite species in infections occurring in the low transmission areas of Western Cameroon. As a consequence, our understanding of the local epidemiology of malaria in Western Cameroon warrants formal investigation. The current proposal is a multi-centre observational study. Its purpose is to characterise the malaria species composition and particularly exposure and burden of P. vivax across malaria endemic settings in Cameroon. It will use multiplex serological methods based on quantitative suspension array on finger-stick blood samples collected from febrile patients of ages 1-100 during two malaria transmission seasons in different eco-climatic regions in Cameroon.
Type 1 diabetes has been poorly characterised, with very sparse information available in the literature about the characteristics of the disease in Africa. Atypical young onset diabetes is often reported by clinicians in sub-Saharan Africa, including patients who have the phenotype of type 1 diabetes but do not appear to have an absolute insulin requirement. The onset of type 1 diabetes in many sub-Saharan African populations seem to occur at later ages (20s to 40s) than what is generally seen in Caucasian populations. The investigators seek to characterise young-onset insulin treated diabetes (clinically diagnosed type 1 diabetes) in sub-Saharan Africa;
