There are about 34 clinical studies being (or have been) conducted in French Guiana. 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.
Intensive Care Unit (ICU) patients are exposed to catheter-related infections with an important morbidity. Catheter colonization is constant but infection is not. Cutaneous dysbiosis could be the missing link. Our study aims to evaluate the evolution of cutaneous microbiota in ICU patients with a central venous catheter in place, through metagenomics. Our main objective is to evaluate the evolution of alpha-diversity, quantified by intra-patient variation of Shannon diversity index (a diversity index used in bacterial metagenomics).
This is an observational, descriptive, cross-sectional, single-center study. The main objective of the study is to estimate the prevalence of the main psychiatric disorders and substance abuse disorders among people living in precarious, excluded and/or wandering on Cayenne and its surroundings
Research Involving the Non-Interventional Human Subject (RIPH category 3). Non-interventional, cross-sectional, multicentre, descriptive and analytical epidemiological study. A cross-sectional, pseudo-anonymous questionnaire focusing on entry and retention in care will be administered to a sample of PLHIV presenting for consultation in one of the GHT hospitals over a 12-month period. A sample of 300 PHAs is envisaged to have sufficient power to highlight the main factors associated with periods of loss of sight. Main objective: - To identify factors associated with loss of sight for more than 12 months among people living with HIV in Guyana Secondary objectives: - To identify factors associated with a delay in the introduction of ARVs among PLHIV in Guyana - To describe the perception of the quality of the announcement of the diagnosis of HIV - To describe the difficulties encountered by PLHIV during their hospital follow-up in French Guyana - To assess the perceived stigma associated with HIV and its consequences in daily life
French Guiana, a French territory located in South America, faces several social challenges including financial insecurity, unemployment and significant immigration. The degraded living conditions of migrants arriving in the territory are likely to put them in a situation of sexual vulnerability that could increase their risk of acquiring HIV (human immunodeficiency virus). This study proposes to conduct a survey of a group of people living with HIV in French Guiana who were born in Haiti and a group of Haitian people who are not HIV positive. With the help of interviewers who speak Haitian Creole, it will allow us to better understand the life paths of people from Haiti and their periods of vulnerability. Investigators will also focus on the use of testing and retention in care for those living with HIV. The results of this work will allow for the mobilization of resources and better adjustment of social support, prevention and care interventions implemented in French Guiana for migrant populations and/or those in precarious situations.
The main objective of the present study is the genotyping of M. leprae strains found in leprosy patients in French Guiana. The secondary objectives are to investigate the presence of M. lepromatosis in these patients, the molecular research of M. leprae resistance to anti-leprosy antibiotics, the study of risk factors for leprosy in humans in Guyana and in particular direct or indirect contact with armadillos, as well as the determination of phylogenetic links between the M. leprae strains found in French Guiana, and with the regional and world reference strains Epidemiology of leprosy in French Guiana.
It is a randomized, controlled, open-label, parallel group study of 3 arms, among patients followed for chronic HIV infection at Cayenne hospital. The main objective of the study is to evaluate the effectiveness of follow-up of these patients by teleconsultation associated or not with health mediation.
Scabies is a Neglected Tropical Disease, particularly important in autochthonous populations. Treatment failures could explain the high prevalence of this disease in Amerindian and Maroon populations of French Guiana. Our main objective is to look for specific sociodemographic risk factors for treatment failure of scabies in the remote areas of French Guiana. A secondary objective is to evaluate the prevalence of scabies and its complications.
In South America, the prevalence of HBV is variable but high (> 8%) in the Amazon basin. In some areas, a third of HBsAg carriers are also infected with HDV, a major comorbidity factor. The pre-core mutations are associated with the negative HBe Ag phenotype which is associated with a more severe course. These mutations are of increasing and high frequency. French Guiana is populated by populations of African, European and Asian origins with chains of viral transmission which are not known and viruses probably of different origins with variable virulence and transmission potentials.
As safety information pertaining to the long-term use of HU remains incomplete in spite of the first safety study (ESCORT-HU), an extension of the latter is proposed. ESCORT-HU Extension study aims at evaluating the long-term safety of Siklos® focusing on some questions regarding its safety when used in current practice in adults and paediatric patients treated with Siklos® and followed for up to 5 years. The study will focus on the following concerns : occurrence and incidence of malignancies, leg ulcers, male fertility impairment and serious unexpected AEs causally related to Siklos®.
In French Guiana, malaria is endemic and two species predominate: P. falciparum and P. vivax. The treatments against Plasmodium vivax malaria are: nivaquine for 3 days against circulating blood parasites and primaquine for 14 days against parasites dormant in the liver. Primaquine can cause iatrogenic hemolytic anemias in patients with favism, i.e. G6PD deficiency. This anemia can be severe enough to cause the death of the deficient patient. Thus, the WHO and HCSP recommendations indicate that a quantitative assay of the activity of this enzyme should be carried out before its prescription. This deficiency is a recessive inherited disease linked to the X chromosome characterized by more or less low levels of enzymatic activity which depends on the genotype of the patients but not only because the phenotype depends on the level of activation of the X chromosome for each cell. Currently, obtaining a G6PD assay in French Guiana is a long process since it is done in mainland France and the pre-analytical conditions are quite demanding. Thus, in areas of transmission of P. vivax, patients usually have a bout of revival before being prescribed primaquine. This period includes: dosing G6PD at a distance from access, obtaining the result and then the nominal ATU to finally obtain and deliver the primaquine.
