There are about 117 clinical studies being (or have been) conducted in Senegal. 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 objective of this study is to evaluate the efficacy, cosmetic acceptability and improvement of the stigmatization of the tested product (2039125 03) used bis in die (BID) for 3 months in adult patients suffering from mild to moderate melasma, or mild to moderate acne induced post-inflammatory hyperpigmentation, or solar lentigo.
This trial will determine if a well-established probiotic, Vivomixx, can modulate the maternal microbiota and ameliorate the maternal environmental enteropathy which compromises growth in the first 1000 days. The probiotic Vivomixx has been used in many thousands of people including pregnant women, both within and outside a research context. This trial is the first in a proposed series of proof-of-concept intervention studies which are intended to provide data to enable a rational selection of interventions to be evaluated at scale in future large scale phase 2 trial in which birth outcomes and postnatal growth will be key endpoints.
Vitamin A deficiency (VAD) is still a serious public health problem in most developing countries. Several strategies are used to prevent and address the consequences of this deficiency and to reduce its prevalence, particularly in Africa. In Senegal, the prevalence of VAD, although low among women of reproductive age, is quite worrying among children under 5 years old. In 2009, the fortification of refined oil with vitamin A was made mandatory in addition to the strategies already in place. The study of the impact of these strategies on the vitamin A status of women and children, showed relatively stable prevalences between 2010 and 2018. However, this study used plasma retinol concentration as an indicator. It is known that evaluation of vitamin A status is relatively insensitive when based on changes in plasma retinol concentrations, which are homeostatically controlled and negatively affected by subclinical infections. Incremental studies in the Dakar region using the modified relative dose response (MRDR) test in children under 2 years of age have indicated adequate vitamin A stores and a low prevalence of vitamin A deficiency in these children. The various strategies to prevent and control vitamin A deficiency have reportedly improved and even increased vitamin A stores in women and children, particularly in the Dakar region. Indeed, the latter benefit from substantial intakes of preformed retinol through the fortification program, and the majority of children under 2 years of age are breastfed. The aim of this study is to use a more sensitive method than plasma retinol, the retinol isotope dilution (RID) test, to assess the actual status of subjects following these different strategies and to better orient the policies implemented in Senegal.
Stunting in young children refers to attenuated linear growth. In the year 2020, 149.2 million children under the age of 5 were stunted, accounting for 22% of stunting globally. Stunting has short- and long-term consequences of increased morbidity and mortality, impairment of neurocognitive development , impaired responses to oral vaccines, and increased risk of non-communicable diseases. Stunting is partly driven by Environmental Enteric Dysfunction (EED), an enteropathic condition characterised by altered gut permeability, infiltration of immune cells and changes in villous architecture and cell differentiation. EED may help explain why nutritional supplementation either during pregnancy or early childhood has minimal value in correcting childhood stunting. Probiotics may serve to overcome the problem of EED through all mechanisms of pathogenicity, by providing additional bacteria that may help in intestinal decolonization of pathogenic microorganisms (changing the microbiological niche), promoting epithelial healing, improving nutrient absorption, and restoration of an appropriate immune balance between tolerance and responsiveness. This trial will explore the conceptual framework, that a well known probiotic, that can improve the composition of the gut microbiota, can reduce biomarkers of intestinal inflammation and gut health. This will restore healthy microbial signalling to the host epithelium, ameliorate barrier function through secretion of mucus and antimicrobial factors, and improve nutrient availability.
A mobile suitcase laboratory for EBOV point-of-care (POC) detection at Ebola treatment centers was successfully implemented in Guinea during the large Ebola virus disease (EVD) outbreak in West-Africa 2014-2015. It was shown that isothermal amplification (Recombinase Polymerase Amplification (RPA)) could be efficiently used to test suspect EVD cases and local teams were trained in and successfully deployed with this fast method. In the frame of this project we want to train teams in DRC and expand RPA testing capacity to the differentials recommended by the WHO. Existing RPA assays for all parameters will be included into a multistrip for simultaneous use. This will be integrated with a simple biosafe extraction method. Implementing this approach and testing in the ongoing EVD outbreak will provide teams in DRC with response capacity for future EVD outbreaks.
Introduction. Comprehensive data on infective endocarditis in developing countries are scarce. Objectives: Description of the characteristics (clinical and microbiological) and assessment of the outcomes of infective endocarditis in low-income countries. Methods : Prospective, Observational, Multicentre study. Inclusion criteria: patients aged over 1 year fulfilling the modified Duke criteria for infective endocarditis. Exclusion criteria: patient included during a previous infective endocarditis episode. Outcomes measures: Mortality at 6 months follow-up; mortality at 1 month follow-up; access to antibiotic treatment (modalities and duration), hospital length of stay and reason for discharge, and cardiac surgery when indicated. Duration: One year (June 2014- June 2015)
