Résumé : International audience
Human immunodeficiency virus (HIV)-associated disseminated Histoplasma capsulatum capsulatum infection often mimics tuberculosis. This disease is well know in the United States but is dramatically underdiagnosed in Central and South America. In the Amazon region, given the available incidence data and the regional HIV prevalence, it is expected that, every year, 1,500 cases of histoplasmosis affect HIV patients in that region alone. Given the mortality in undiagnosed patients, at least 600 patients would be expected to die from an undiagnosed but treatable disease. The lack of a simple diagnostic tool and the lack of awareness by clinicians spiral in a vicious cycle and made a major problem invisible for 30 years. The HIV/acquired immunodeficiency syndrome community should tackle this problem now to prevent numerous avoidable deaths from HIV-associated histoplasmosis in the region and elsewhere.

Résumé : International audience
Reports on dengue morbidity in patients with sickle cell disease (SCD) are scarce. Dengue is arthropod-borne viroses due to dengue virus (DENV) and affects populations with a high prevalence of SCD; therefore, the risk of morbidity may be increased.To determine the impact of dengue infection in SCD patients, we reviewed medical records during a vast outbreak of dengue virus serotype-2 (DENV-2) in French Guiana in 2012-2013. We identified 10 cases of laboratory-confirmed dengue infection;these were classified into A, B and C categories based on levels of severity of dengue according to World Health Organisation (WHO). The average age of SCD patients was 18.2 years. 1, 6 and 3 cases were classified as A, B and C WHO severity criteria, respectively. All patients had an important decrease in haematocrit (while one of the WHO severity criteria is the increase of haematocrit). Only one patient had decreased platelet count. Seven cases had vaso-occlusive crisis (VOC), six patients developed acute hepatitis and eight had a simultaneous bacterial infection. Six of them needed a blood transfusion. The results suggested that the WHO severity laboratory criteria of hemoconcentration and platelet counts were not helpful in themanagement of SCD patients. The morbidity was mainly caused by specific complications of SCD, especially VOC, likely facilitated by vascular endothelial damages consecutive to dengue fever, severe haemolysis, hepatitis and bacterial co-infections.

Résumé : International audience
BACKGROUND: Histoplasmosis is an endemic fungal infection in French Guiana. It is the most common AIDS-defining illness and the leading cause of AIDS-related deaths. Diagnosis is difficult, but in the past 2 decades, it has improved in this French overseas territory which offers an interesting model of Amazonian pathogen ecology. The objectives of the present study were to describe the temporal trends of incidence and mortality indicators for HIV-associated histoplasmosis in French Guiana. METHODS: A retrospective study was conducted to describe early mortality rates observed in persons diagnosed with incident cases of HIV-associated Histoplasma capsulatum var. capsulatum histoplasmosis admitted in one of the three main hospitals in French Guiana between 1992 and 2011. Early mortality was defined by death occurring within 30 days after antifungal treatment initiation. Data were collected on standardized case report forms and analysed using standard statistical methods. RESULTS: There were 124 deaths (45.3%) and 46 early deaths (16.8%) among 274 patients. Three time periods of particular interest were identified: 1992-1997, 1998-2004 and 2005-2011. The two main temporal trends were: the proportion of early deaths among annual incident histoplasmosis cases significantly declined four fold (χ2, p<0.0001) and the number of annual incident histoplasmosis cases increased three fold between 1992-1997 and 1998-2004, and subsequently stabilized. CONCLUSION: From an occasional exotic diagnosis, AIDS-related histoplasmosis became the top AIDS-defining event in French Guiana. This was accompanied by a spectacular decrease of early mortality related to histoplasmosis, consistent with North American reference center mortality rates. The present example testifies that rapid progress could be at reach if awareness increases and leads to clinical and laboratory capacity building in order to diagnose and treat this curable disease.

Résumé : International audience
French Guiana, the French territory most affected by human immunodeficiency virus (HIV) (1.3% of pregnant women), is also endemic for human T lymphotropic virus 1 (HTLV1). The objective of this study was to determine if the HTLV1/HIV coinfected patients had particular characteristics. All HIV-infected patients having a computerized medical file containing an HTLV1 serology were included: there were 1,333 HIV monoinfections and 76 HTLV1/VIH coinfections. The prevalence of HTLV1/HIV coinfections was 5.39%. Women (odds ratio [OR] = 1.91[1.13-3.24]), subjects > 40 years of age, and patients of Surinamese origin (OR = 2.65 [1.25-5.61]) were overrepresented among the coinfected. CD4 count at the time of diagnosis and viral loads were higher among coinfected patients. The clinical stage was not significantly different between the two groups. The number of CD4 cells was not higher among the coinfected, unlike most reports from the literature. Prevalence of HTLV1 among HIV-infected patients is high in French Guiana, and physicians seem to omit the prescription of serology for this potentially serious coinfection.

Résumé : International audience
In disease-endemic areas, histoplasmosis is the main differential diagnosis for tuberculosis among human immunodeficiency virus (HIV)-infected patients. However, no study has compared the two diseases. Thus, the objective of this study was to compare tuberculosis and histoplasmosis in HIV-infected patients. A population of 205 HIV-infected patients (99 with tuberculosis and 106 with histoplasmosis) hospitalized in Cayenne, French Guiana during January 1, 1997-December 31, 2008 were selected retrospectively from the French Hospital Database on HIV. Multivariate analysis showed that tuberculosis was associated with cough (adjusted odds ratio [AOR] = 0.20, 95% confidence interval [CI] = 0.05-0.73) and a C-reactive protein level > 70 mg/L (AOR = 0.98, 95% CI = 0.97-0.99). Variables associated with disseminated histoplasmosis were a γ-glutamyl transferase level > 72 IU/L (AOR = 4.99, 95% CI = 1.31-18.99), origin from French Guiana (AOR = 5.20, 95% CI = 1.30-20.73), disseminated localization (AOR = 6.40, 95% CI = 1.44-28.45), a concomitant opportunistic infection (AOR = 6.71, 95% CI = 1.50-29.96), a neutrophil count < 2,750 cells/mm(3) (AOR = 10.54, 95% CI = 2.83-39.24), a CD4 cell count < 60 cells/mm(3) (AOR = 11.62, 95% CI = 2.30-58.63), and a platelet count < 150,000/mm(3) (AOR = 19.20, 95% CI = 3.35-110.14). Tuberculosis and histoplasmosis have similarities, but some factors show a greater association with one of these diseases. Thus, adapted therapeutic choices can be made by using simple clinical and paraclinical criteria.

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
ABSTRACT: Eclipsed by the debates about malaria incidence and severity in individual patients, malaria transmission in helminth-infected persons has so far received very little attention. Studies in humans have shown increased malaria incidence and prevalence, and a trend for a reduction of symptoms in patients with malaria. This suggests that such patients could possibly be less likely to seek treatment thus carrying malaria parasites and their gametocytes for longer durations, therefore, being a greater potential source of transmission. In addition, in humans, a study showed increased gametocyte carriage, and in an animal model of helminth-malaria co-infection, there was increased malaria transmission. These elements converge towards the hypothesis that patients co-infected with worms and malaria may represent a hub of malaria transmission. The test of this hypothesis requires verifying, in different epidemiological settings, that helminth-infected patients have more gametocytes, that they have less symptomatic malaria and longer-lasting infections, and that they are more attractive for the vectors. The negative outcome in one setting of one of the above aspects does not necessarily mean that the other two aspects may suffice to increase transmission. If it is verified that patients co-infected by worms and malaria could be a transmission hub, this would be an interesting piece of strategic information in the context of the spread of anti-malarial resistance and the malaria eradication attempts.

Résumé : International audience
The French overseas territories in the Americas are the French territories most affected by HIV. Crack cocaine users are particularly impacted. The objective of this study was to describe sexual risk behaviors and inconsistent condom use among crack cocaine users. A total of 640 crack cocaine users were interviewed. The sampling method was non-probabilistic. An anonymous standardized questionnaire of 110 questions was used. Over a third of persons did not use condoms systematically with casual sex partners (36.2%) or commercial sex partners (32.3%), and 64% did not use condoms systematically with regular sex partners. In a context of multiple sexual partnerships, frequent forced sex, and insufficient HIV testing, the lack of systematic condom use may favor the spread of HIV. Different predictive factors of inconsistent condom use were identified, depending on the type of partner, with a log binomial regression. However, among the predictor variables identified, two predictive factors frequently occur among the different type of sex partners: high perceived risk of HIV and self-perceived capacity to persuade a sex partner to use condom. These results pointed towards interventions improving access to rights and raising perceived self-efficacy.

BACKGROUND:In French Guiana, cervical cancer is the second most frequent cancer in females. The objective of the present study was to describe the prevalence of HPV infections in women with normal cervical cytology living in the remote villages of French Guiana.METHODS:Before the study, the study team communicated in the remote villages on the importance of screening. All women from the target population were offered to participate. They signed informed consent during inclusion and then had a concomitant HPV-test and cervical smear. Only women with normal cytology and a good quality smear were analyzed. The detection of HPV-DNA was performed using the GREINER-BIO-ONE kit.RESULTS:Overall, 27.2% of women with normal cervical cytology had a positive HPV-test. There was a U-shaped evolution of prevalence with women over 50 years having the highest HPV prevalence, followed by the 20 to 29 years group. The most prevalent HPV genotypes were HPV 53(3.52%), 68(3.33%), 52(2.59%), 31(2.22%) and 16 (1.85%). The proportion of HPV 16 among HPV-infected women was 6.8%.CONCLUSIONS:HPV prevalence in cytologically normal women was very high. The most prevalent genotypes were very different from what is usually described in the world, and notably in South America.

Résumé : International audience
BackgroundMalaria is endemic in French Guiana, an overseas territory of France on the Guiana Shield. Since 2005, notified malaria cases are decreasing. However, new data show that malaria affects many Brazilian gold miners working illegally in French Guiana, the majority of whom are not counted in official data. In addition, one major concern is the usual practice of improper self-treatment in this mining population, raising fear of the development of antimalarial resistance. This prospective study, conducted in 2015, aimed to estimate the prevalence of Plasmodium spp. in illegal gold miners working in French Guiana. MethodsThe recruitment of gold miners was carried out in resting sites along the French Guiana-Suriname border, where they go for supplies, medical care or leisure. After recording agreement, three malaria diagnostic methods were performed: rapid diagnostic test, microscopy and PCR,ResultsAmong 421 persons recruited in the study, malaria prevalence, detected by nested-PCR, was 22.3% (CI=[18.3-26.3], n=94/421) of which 84% were asymptomatic. ConclusionThis significant malaria reservoir in a mobile and illegal population with difficult access to a health care system raises the threat of artemisinin resistance and puts the population of the Guiana Shield at risk of new transmission foci while countries of the region aim at malaria elimination. Even though French legislation may hamper dealing with this population, France must face the reality of malaria in illegal gold miners in order to meet its commitment to malaria elimination.

Résumé : International audience
From September 2013 to July 2014, several gold miners working in the tropical forest consulted the Maripasoula Health Center in French Guiana for edema and findings consistent with right cardiac failure. Of the 42 cases of beriberi that were diagnosed, one patient died. The laboratory and clinical investigation demonstrated vitamin B1 deficiency in most of the patients tested. Furthermore, 30 of 42 patients responded favorably to 500 mg of intravenous or intramuscular thiamine supplementation. In addition, dietary investigation showed insufficient thiamine intake in these patients. We concluded that patients had acquired beriberi because of diet restrictions, hard labor, and infectious diseases, notably malaria. In 2016, cases were still being reported. We recommend screening for compatible symptoms in gold miners, thiamine supplementation, and nutritional intervention

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 Mycobacterium ulcerans infection is the third most common mycobacterial disease in the world after tuberculosis and leprosy. To date, transmission pathways from its environmental reservoir to humans are still unknown. In South America, French Guiana has the highest reported number of M ulcerans infections across the continent. This empirical study aimed to characterise the epidemiology of M ulcerans infection in French Guiana between 1969 and 2013.MethodsData were collected prospectively mainly by two dermatologists at Cayenne Hospital’s dermatologydepartment between Jan 1, 1969, and Dec 31, 2013, for age, date of diagnosis, sex, residence, location of the lesion,type of lesion, associated symptoms, and diagnostic method (smear, culture, PCR, or histology) for all confirmed andsuspected cases of M ulcerans. We obtained population data from censuses. We calculated mean M ulcerans infectionincidences, presented as the number of cases per 100 000 person-years.Findings 245 patients with M ulcerans infections were reported at Cayenne Hospital’s dermatology department duringthe study period. M ulcerans infection incidence decreased over time, from 6·07 infections per 100 000 person-years(95% CI 4·46–7·67) in 1969–83 to 4·77 infections per 100 000 person-years (3·75–5·79) in 1984–98 and to3·49 infections per 100 000 person-years (2·83–4·16) in 1999–2013. The proportion of children with infections alsodeclined with time, from 42 (76%) of 55 patients in 1969–83 to 26 (31%) of 84 in 1984–98 and to 22 (21%) of 106 in1999–2013. Most cases occurred in coastal areas surrounded by marshy savannah (incidence of 21·08 per100 000 person-years in Sinnamary and 21·18 per 100 000 person-years in Mana). Lesions mainly affected limbs (lowerlimbs 161 [66%] patients; upper limbs 60 [24%] patients). We diagnosed no bone infections.Interpretation The decrease of M ulcerans infection incidence and the proportion of children with infections over a45 year period in this ultra-peripheral French territory might have been mostly driven by improving living conditions,prophylactic recommendations, and access to health care.

To assess the prevalence of malaria among illegal gold miners in the French Guiana rainforest, we screened 205 miners during May-June 2014. Malaria prevalence was 48.3%; 48.5% of cases were asymptomatic. Patients reported self-medication with artemisinin-based combination therapy. Risk for emergence and spread of artemisinin resistance among gold miners in the rainforest is high.

AbstractBackgroundSuicide rates in prison are high and their risk factors are incompletely understood. The objective of the present study is to measure the risk of suicide and its predictors in the only prison of multicultural French Guiana.MethodsAll new prisoners arriving between September 2013 and December 2014 were included. The Mini International Neuropsychiatric Interview (MINI) was used and socio-demographic data was collected. In order to identify the predictors of suicide risk multivariate logistic regression was used.ResultsOf the 707 prisoners included 13.2% had a suicidal risk, 14.0% of whom had a high risk, 15.1% a moderate risk and 41.9% a low risk. Predictive factors were depression (OR 7.44, 95% CI: 3.50–15.87), dysthymia (OR 4.22, 95% CI: 1.34–13.36), panic disorder (OR 3.47, 95% CI: 1.33–8.99), general anxiety disorder (GAD) (OR 2.19, 95% CI: 1.13–4.22), men having been abused during childhood (OR 21.01, 95%, CI: 3.26–135.48), having been sentenced for sexual assault (OR 7.12, 95% CI: 1.98–25.99) and smoking (OR 2.93, 95%, CI 1.30–6.63).ConclusionThe suicide risk was lower than in mainland France, possibly reflecting the differences in the social stigma attached to incarceration because of migrant populations and the importance and trivialization of drug trafficking among detainees. However, there were no differences between nationalities. The results reemphasize the importance of promptly identifying and treating psychiatric disorders, which were the main suicide risk factors.

Introduction Le chikungunya (CHIKV) est un alphavirus ré-émergent depuis 10 ans responsable de nombreuses épidémies. Chez certains patients, il est à l'origine de troubles musculo-squelettiques et de polyarthropathies inva-lidants et persistants plus de 3 mois, définissant la forme chronique du chikun-gunya (CHIKC). Afin de déterminer la prévalence du CHIKC, nous avons mené une cohorte prospective de patients ambulatoires lors de la dernière épi-démie en outre-mer. Secondairement, nous avons recherché les facteurs de risques associés.

Résumé : International audience
Border areas are particular “hot spots” generating high levels of HIV vulnerability and facing great challenges to control epidemics. The objective of this study is to describe the sociodemographic, clinical and biological profiles of newly HIV diagnosed people at the French Guiana - Suriname border, to construct an HIV care cascade and compare it with the Surinamese one. HIV-patients aged over 15 years newly diagnosed in western French Guiana in 2011 and 2012 were included in a retrospective cohort study. Patients were identified using different sources (n=121). The male-to-female ratio was 0.8, 85% of the patients were of foreign origin, 72% were undocumented migrants, 21% were living in Suriname and 48% had baseline CD4 cell counts <200 cells/mm3. After one year, 34% were lost to follow-up, 54% received treatment, 34% had controlled viremia and 6% died. We observed a disappointing HIV cascade, like that of Suriname, requiring to develop a coordinated healthcare offer on both sides of the border. Targeted efforts through a bi-national collaboration are needed to address the specific issues of cross-border patients to reach the 90*3 UNAIDS’s diagnosis, link to care and treatment targets and better control the local epidemic

Résumé : National audience
Une Brésilienne de 39 ans est adressée à l’hôpital de Cayenne pour des céphalées, une confusion fébrile et une altération de l’état général. Six mois plus tôt, une infection par le VIH avait été révélée (charge virale de 147 615 copies/ ml ; CD4 à 56/ mm3), au Brésil, par un tableau de tuberculose pleuro-pulmonaire non documentée. Elle suit depuis un traitement antirétroviral et une quadrithérapie antituberculeuse, sans cotrimoxazole, traitement toujours en cours à son entrée.

Résumé : International audience
BACKGROUND:Dengue fever is the most important arboviral infection that affects humans, particularly in tropical and subtropical regions. Here, we provide the first comprehensive overview of the severity of dengue epidemics in French Guiana.METHODOLOGY/PRINCIPAL FINDINGS:We monitored hospitalized cases between 2008 and 2013. Detailed clinical features and biological parameters were collected on a daily basis from all cases. Among the 1,356 cases, 216 (16%) were classified according to the WHO 2009 classification as dengue without warning signs (WS), 926 (68%) were classified as dengue with WS and 214 (16%) were classified as severe dengue. The severity rates were similar between the three major epidemics that occurred during the study period, whereas the hospitalization rate was highest in 2013. Fluid accumulation, aspartate aminotransferase (ASAT) counts>193 IU/L and platelet counts<75,000 cells/mm3 were associated with dengue severity.CONCLUSIONS/SIGNIFICANCE:Our findings provide a recent epidemiological description of the severity of dengue epidemics in French Guiana. These results highlight the potential impacts and consequences of implementing the WHO 2009 classification on hospital activity. Future studies should include virological and immunological investigations of well-documented serum samples
