Résumé : International audience
In French Guiana, the prevalence of HIV among pregnant women along the Maroni river, has risen from 0 to over 1% in the 1990's. Despite this sharp increase, no behavioural surveillance study has ever taken place in this border region. The present study showed that an important proportion of boatmen have risky sexual behaviour. These results underline the importance of targeting prevention interventions on this population that is not currently receiving specific HIV prevention messages.

Résumé : International audience
Background: Guadeloupe is the region of France with the second highest prevalence of HIV. Methods: To determine the risk factors for being lost to follow-up (LFU), a retrospective cohort study of 2,732 patients followed between 1988 and 2009 was conducted, and determined which variables were related to being LFU, i.e. permanently disappearing from HIV clinics or coming back after more than one year of missed appointments. Results: The incidence rate for permanent follow-up interruption was 9 per 100 person-years (8.3-9.7 personyears). The median time of LFU was 6.4 years (interquartile range 3-16.9 years). Cox modelling showed that the younger age groups (HR: 1.60[1.30-2.10], p=0.000) and patients diagnosed before 1997 (HR: 4.80[3.50-6.50], p=0.000) were significantly more likely to be permanently LFU. However, patients treated with HAART had a lower risk of being LFU (HR: 0.63[0.51-0.80], p=0.000). Conclusion: These results suggest that some patients may have died. They also allow to quantify the magnitude of a major yet often under-recognized problem and to identify its predictors in the context of Guadeloupe. This could help clinicians improve patient retention.

Résumé : International audience
In French Guiana, the age-standardized incidence rate of cervical cancer is four times higher than in France and the mortality rate 5.5 times higher. A survival study revealed that stage at diagnosis was the main factor influencing the prognosis, showing that early detection is crucial to increase cervical cancer survival. The present study aimed at evaluating the cervical cancer screening rate between 2006 and 2011 by age and for 3-years period in French Guiana. All pap smears realised in French Guiana were analysed in two laboratories allowing exhaustive review of screening data. The screening rate was estimated at about 54% from 2006 to 2011, with a statistical difference between coastal and rural area (56.3% versus 18.7%).Although the methodological difference did not allow comparisons with mainland France, these results could be used to evaluate the impact of organised cervical cancer screening by the French Guiana Association for Organized Screening of Cancers implemented in French Guiana since 2012.

Résumé : International audience
Objective: In order to determine how risk factors of death among HIV-infected patients in French Guiana interact with one another and to define high risk population segments, an alternative statistical method to Cox proportional hazards models was used. Patients and methods: Data from HIV+ patients followed in the three main hospitals of French Guiana were used. Data were extracted from the prospective French Hospital Database for HIV (FHDH). To examine the nature of the relationships between time of death since the first consultation and a set of predictor variables (age at enrolment, gender, nationality, CD4 count at enrolment, presence or absence of HAART at enrolment, a declared addiction, and mode of acquisition of the virus) a survival tree analysis was used. Survival rates at 5 years and 10 years and their 95% confidence interval were also calculated. Results: This analysis permitted to reveal a new specific subgroup of HIV+ patients particularly at risk in French Guiana not already mentioned in the literature: the HIV+ female patients with a declared addiction. Conclusions: Prevention and care in this vulnerable segment of the HIV+ population identified by this methodology should be reinforced.

Résumé : International audience
Resistance to artemisinin casts a shadow on the fight against malaria. The importance of illegal gold miners and of malaria in isolated regions of French Guiana constitutes a threat that endangers the fight against malaria in the Amazon. The hurdles of French laws and the remoteness of the territory from France make it impossible for the system to adapt to the problem of total inaccessibility of an important part of the malaria problem. Transmission is high in these areas and gold miners self-medicate with erratic regimens of artemisinin combinations, thus creating perfect conditions for the emergence of resistance. What needs to be done is being done, but within the limits of national law, with some results. However, facing the same difficult problem, Suriname shows more flexibility and is doing much better than French Guiana despite having lower resources. Local authorities in French Guiana cannot overrule the laws that block appropriate malaria care from reaching a third of malaria-exposed persons. Thus the health authorities in France should take immediate calibrated legislative and financial measures to avoid a predictable disaster.

Résumé : International audience
Background: In French Guiana, a recent study has shown that a major part of the histoplasmosis incidence temporal fluctuations could be explained by climatic factors and thus postulated that disseminated histoplasmosis cases could be in a large proportion due to new infections. The description of the seasonal pattern of histoplasmosis could potentially help to test this new hypothesis. Patients and methods: A study using prospective data from the French Hospital Database for HIV was conducted in order to determine seasonal variations of the incidence of first cases of disseminated histoplasmosis in HIV persons in Cayenne, French Guiana. Single failure Cox proportional hazards models were used. Results: After adjusting for CD4 counts and antiretroviral treatment, the incidence of disseminated histoplasmosis was significantly higher during the Short Wet Season-Long Dry Season than during the Short Dry Season-Long Wet Season (Adjusted Hazard ratio 1.7 (1.1-2.5), P= 0.01). Conclusion: This result gives both valuable epidemiologic information to clinicians and a supplementary argument in favour of the hypothesis that an important proportion of cases were due to recent exposure. Therefore, the use of a primary prophylaxis must be discussed in French Guiana.

Résumé : International audience
Sickle cell disease (SCD) is a significant problem in the Caribbean, where many individuals have African and Asian forebears. However, reliable prevalence data and specific health care programs for SCD are often missing in this region. Closer collaboration between Caribbean territories initiated in 2006 to set up strategies to promote better equity in the health care system for SCD patients led to the formation of CAREST: the Caribbean Network of Researchers on Sickle Cell Disease and Thalassemia. We present the effectiveness of collaborations established by CAREST to promote SCD newborn screening programs and early childhood care, to facilitate health worker training and approaches for prevention and treatment of SCD complications, and to carry out inter-Caribbean research studies.

Résumé : International audience
Histoplasmosis is the first cause of acquired immunodeficiency syndrome (AIDS) and AIDS-related deaths in French Guiana. Cohort data were used to determine whether primary prophylaxis with 100 mg itraconazole for patients with CD4 counts < 150/mm(3) was cost-effective with different scenarios. For a scenario where 12% of patients died, 60% were aware of their human immunodeficiency virus (HIV) infection and adherence was only 50%, primary prophylaxis would prevent 1 death and 9 cases of histoplasmosis for a cost of 36,792 Euros per averted death, 1,533 per life-year saved, 4,415 Euros per averted case, when only counting the costs of itraconazole prophylaxis. Taking into account the total costs of hospitalization showed that primary prophylaxis would allow a savings of 185,178 Euros per year. Even in a scenario of low adherence, primary prophylaxis would be cost-effective in French Guiana, and presumably in the rest of the Guianas and the Amazon.

Résumé : International audience
Background: The aim of this study was to identify the predictive factors of HIV disclosure to the sex partner in HIV pregnant women in Cayenne (French Guiana). Methods: A case control study was conducted including all deliveries in Cayenne from 2003 to 2010. For each case, a standardized questionnaire including epidemiological, clinical, and biological data was administered. Thirty-four women in the first group and 95 in the control group were included in the study. Results: The logistic regression showed that the variables that independently predicted HIV disclosure to the sex partner were the existence of a profession (OR=5.62, IC95% =1.3-24.26, p=0.021), disclosure to the doctor (OR=12.65, IC95% =2.87-55.8, p<0.001), the negative representations of HIV (OR=5.99, IC95% =1.17-30.69, p=0.032). The partner's HIV status was also linked to the outcome (OR=0.01, IC95% =0.001-0.07, p<0.001). Conclusion: These predictive factors should be considered in positive prevention programs and prevention of mother to child transmission.
