The epidemiology and management of stroke in French Guiana.

ABSTRACT: BACKGROUND:French Guiana has the highest incidence of ischemic and hemorrhagic stroke of all French territories. However, there is no further information on the epidemiology and management of stroke in French Guiana. Our goal was to describe the characteristics of patients in French Guiana in order to generate hypotheses regarding the determinants explaining the magnitude of this public health problem. METHODS:We used the data of the French multicentre INDIA prospective cohort study which included consecutive patients aged >?18?years with a first-ever stroke from June 2011 to October 2014. For the present study, only patients with ischemic or hemorrhagic stroke admitted in one of the 3 participating hospitals were analyzed. RESULTS:Among the 298 patients (mean age 62.2?±?14.5?years, 63.7% man) included in French Guiana, 52% were born abroad. Most strokes were ischemic strokes (79%), 14% of which were thrombolyzed. Hypertension (70.2%), history of smoking (22%) and diabetes (25%) were the most common risk factors and 28.4% of patients had known but untreated hypertension. Overall 89 (38%) patients with ischemic stroke were admitted less than 4.5?h after the first symptoms. In-hospital mortality was greater for intracerebral hemorrhage (18.7%) than for ischemic stroke (4.2%). Overall, 84.5% had health insurance coverage and among these, 41.9% had CMU, the universal health insurance for the poor. CONCLUSIONS:The present study is the first epidemiologic description of stroke in French Guiana. The comparisons of these results show that stroke patients in French Guiana are epidemiologically atypical because they are younger, and more likely to be males than patients in mainland France. Stroke risk factors and delay between stroke and hospital admission were comparable with what is observed in France, suggesting that efforts should focus on primary care and social inequalities of health to alleviate the main determinants of stroke in French Guiana.

Project description:BackgroundIn French Guiana poverty is widespread and specialized care is lacking. We aimed to compare strokes between precarious and non-precarious patients within French Guiana and to compare the epidemiology of ischemic strokes and their outcomes between French Guiana and mainland France.MethodsA multicenter prospective cohort examined the influence of social inequalities on stroke characteristics. Consecutive patients aged > 18 years admitted for an acute ischemic stroke, confirmed by neuroimaging were eligible. Exclusion criteria were a history of symptomatic stroke, presence of other short-term life-threatening diseases and inability to contact patients by telephone during follow-up. Social deprivation was measured using the EPICES score, which is based on a multidimensional questionnaire.ResultsOverall, 652 patients with ischemic stroke were included. The patients in French Guiana were 7 years younger, were more frequently male, of sub-Saharan ancestry, they had a low level of education, and were more often precarious (67.7%) than the patients included in Dijon (39.2%). The origin of the ischemic stroke was predominantly lacunar for patients included in French Guiana and cardioembolic for patients included in Dijon, with greater severity for patients included in Dijon. The proportion of patients with known pre-stroke hypertension, diabetes, or a history of Transient Ischemic Accident was greater in French Guiana than in Dijon. In contrast, hypercholesterolemia, atrial fibrillation, and history of Myocardial Infarction were more frequently found in patients included in Dijon than in patients included in French Guiana. Fibrinolysis was less frequent in French Guiana than in Dijon, 24% of patients arriving early enough receiving thrombolysis in French Guiana vs. 45% in Dijon, P < 0.0001. However, after adjustment for patient characteristics, the effect of the center on the use of fibrinolysis disappeared. When comparing precarious and non-precarious patients within French Guiana, the main difference was the younger age and the lower mortality of precarious patients-notably immigrants.ConclusionPrecariousness was widespread in French Guiana. Within French Guiana, despite a younger age among foreigners than French patients, the risk factors, mechanisms, and outcomes were homogenous across socioeconomic strata. The observed differences between the two contrasted French territories suggested that, beyond health inequalities, the epidemiology of cardiovascular risk factors may differ between French Guiana and mainland France.

Project description:BackgroundThe epidemiological surveillance of malaria is a necessary intervention for eliminating the disease from the planet. The international border zones of the Amazon continue to be highly vulnerable to malaria since population mobility impedes elimination. Although in the past few years, cases of malaria have had an essential reduction in Brazil, this trend was not confirmed in municipalities along the border. This study aimed to establish the epidemiology of the disease during the last 13 years in Oiapoque, a Brazilian municipality at the international border with French Guiana, an overseas department, to develop strategies for the control/elimination of malaria in these areas.ResultsData collected from 2003 to 2015 from the Malaria Epidemiological Surveillance System was used. It was found that, despite the important reduction in cases (68.1%), the annual parasite index remained a high epidemiological risk. The disease is seasonal in that the period of highest transmission occurs between September and December. Between 2003 and 2015, eight outbreaks were identified, with one of these lasting 15 months between August 2006 and October 2007. There were changes in the epidemiological profile, with imported cases representing 67.7% of cases from 2003 to 2007 and representing 32.9% of cases from 2008 to 2015 (p < 0.01). The greatest number of cases was among Brazilians coming from the artisanal gold mines of French Guiana. There were also changes in the profile of autochthonous malaria with an increase in urban cases from 14.3% in 2003 to 32.3% in 2015 (p < 0 .01). The burden of malaria in indigenous areas was also very high (67.3% in rural areas) in 2015. There were changes in the parasite species profile with a significant decrease of cases of Plasmodium falciparum (p = 0.01). Children under 15 years old, representing 9.7% of cases at the onset of the study, accounted for 34.2% of case notifications (p < 0.01) in 2015. Also, 74% of cases in 2003 and 55.9% in 2015 (p < 0.01) were among men.ConclusionsThe fragility of local health services in cross-border areas continues to be an obstacle for malaria elimination.
