Résumé : International audience
Background: HCV treatment uptake has drastically increased in HIV-HCV coinfected patients in France since direct-acting antiviral (DAA) treatment approval, resulting in HCV cure in 63% of all HIV-HCV patients by the end of 2015. We investigated the impact of scaling-up DAA on HCV prevalence in the whole HIV population and in various risk groups over the next 10 years in France using a transmission dynamic compartmental model.Methods: The model was based on epidemiological data from the French Dat’AIDS cohort. Eight risk groups wereconsidered, including high-risk (HR) and low-risk (LR) men who have sex with men (MSM) and male/female heterosexuals,intra-venous drug users, or patients from other risk groups. The model was calibrated on prevalence and incidence dataobserved in the cohort between 2012 and 2015.Results: On January 1, 2016, 156,811 patients were registered as infected with HIV in France (24,900 undiagnosedpatients) of whom 7938 (5.1%) had detectable HCV-RNA (722 undiagnosed patients). Assuming a treatmentcoverage (TC) rate of 30%/year (i.e., the observed rate in 2015), model projections showed that HCV prevalenceamong HIV patients is expected to drop to 0.81% in 2026. Sub-analyses showed a similar decrease of HIV-HCVprevalence in most risk groups, including LR MSM. Due to higher infection and reinfection rates, predicted prevalencein HR MSM remained stable from 6.96% in 2016 to 6.34% in 2026. Increasing annual TC rate in HR MSM to 50/70%would decrease HCV prevalence in this group to 2.35/1.25% in 2026. With a 30% TC rate, undiagnosed patients wouldaccount for 34% of HCV infections in 2026.Conclusions: Our model suggests that DAA could nearly eliminate coinfection in France within 10 years for most riskgroups, including LR MSM. Elimination in HR MSM will require increased TC.

Résumé : International audience
Diagnosis of toxoplasmic encephalitis (TE) in patients with AIDS is not straightforward because clinicians rely initially on an empiric diagnosis based on clinical and radiographic improvement to specific anti-Toxoplasma gondii therapy. There is therefore a need for biological tools to improve the diagnosis of TE, especially in tropical areas where this diagnosis is likely to be underestimated. The use of PCR testing in blood samples for the diagnosis of TE has been limited by its poor sensitivity in the studies conducted in Europe. In tropical South America, the results of PCR sensitivity in blood samples were controversial. Considering that T. gondii strains from tropical South America have substantial genetic and pathogenic differences with those from USA and Europe, it is therefore important to re-evaluate the performance of the PCR assay in blood samples for the diagnosis of TE in AIDS patients from this region. Our results showed that the only interest of PCR would be in the most severe forms of TE with altered consciousness because PCR is more likely to be positive. We also provided important genotyping data on T. gondii strains isolated in human cases of toxoplasmosis in the Caribbean and in South America.

Résumé : International audience
The aim of the study was to investigate the impact of first-line combined antiretroviral therapy (cART) regimen on the course of CD8 + T-cell counts in human immunodeficiency virus (HIV)-infected patients. A retrospective observational study conducted on the French DAT'AIDS Cohort of HIV-infected patients. We selected 605 patients initiating a first-line cART between 2002 and 2009, and which achieved a sustained undetectable HIV plasma viral load (pVL) for at least 12 months without cART modification. The evolution of CD8 + T-cell counts according to cART regimen was assessed. CD8 + T-cell counts were assessed in 572 patients treated with 2NRTIs+1PI/r (n= 297), 2NRTIs+1NNRTI (n= 207) and 3NRTIs (n= 68). In multivariate analysis, after 12 months of follow-up, the 3NRTIs regimen was associated with a significantly smaller decrease of CD8 + T-cell count compared with NNRTI-containing regimens (–10.2 cells/mL in 3NRTIs vs –105.1 cells/mL; P=0.02) but not compared with PI-containing regimens (10.2 vs –60.9 cells/mL; P=0.21). After 24 months, the 3NRTIs regimen was associated with a smaller decrease of CD8 + T-cell count and % compared with PI/r-and NNRTI-containing regimens (0.2 in 3NRTIs vs –9.9 with PI/r-regimens, P=0.001, and vs –11.1 with NNRTI-regimens, p < 0.0001). A focus analysis on 11 patients treated with an INSTI-containing cART regimen during the study period showed after 12 months of follow-up, a median decrease of CD8 + T-cell count of –155 [inter quartile range: –302; –22] cells/mL. Our data highlight the fact that cART regimens have differential effects on CD8 pool down regulation.

ObjectivesTo compare the efficacy, in current clinical practice, of ă first regimens containing abacavir with lamivudine (ABC/3TC) or ă tenofovir with emtricitabine (TDF/FTC) in patients with baseline viral ă load 100000 HIV-1 RNA copies/mL. ă MethodsUsing a prospective cohort, we selected all patients starting a ă first HIV regimen based either on ABC/3TC or on TDF/FTC. The propensity ă score (PS) method was used to limit the indication bias due to the ă observational nature of the data. Adjusting and weighting methods via PS ă were used to compare the effectiveness of a first regimen containing ă ABC/3TC or TDF/FTC. The primary outcome was treatment failure by month ă 12 (M12). ă ResultsOverall, 2781 patients started an antiretroviral (ARV) regimen ă with ABC/3TC or TDF/FTC each in combination with efavirenz, boosted ă atazanavir or boosted darunavir. Among the 2472 uncensored patients ă before M12, 962 (39%) had a baseline viral load 100000 copies/mL of ă whom 294 were in treatment failure at or before M12. Our analyses showed ă no difference between ABC/3TC and TDF/FTC in the risk of treatment ă failure at M12 in patients starting an ARV regimen with a high viral ă load (100000 copies/mL). ă ConclusionsUsing a large prospectively collected cohort of patients ă seeking care in France, we found no evidence that ABC/3TC based regimens ă led to more failures than TDF/FTC based ones in patients with high ă baseline viral loads.

Résumé : International audience
INTRODUCTION:The frequency, the clinical characteristics, and the prognosis of dengue is highly variable. Dengue fever is associated with a range of neurological manifestations. The objective of the present study was to determine the incidence of neurological signs and their predictive factors using data from cases of dengue seen and followed in Cayenne Hospital during the Dengue 2 epidemic in 2013.METHODS:In 2013, a longitudinal study using data from all cases of dengue seen in Cayenne hospital was collected. Medical records used a standardized form to collect demographic information, clinical signs and biological results and the date at which they were present. The analysis used Cox proportional modeling to obtain adjusted Hazard ratios.RESULTS:A total of 1574 patients were included 221 of whom developed central nervous system signs. These signs were spontaneously resolutive. There were 9298person days of follow-up and the overall incidence rate for central nervous system signs was 2.37 per 100 person-days. The variables independently associated with central nervous system anomalies were headache, Adjusted Hazard ratio (AHR) = 1.9(95%CI = 1.4-2.6), bleeding AHR = 2 ((95%CI = 1.3-3.1), P = 0.001, abdominal pain AHR = 1.9 ((95%CI = 1.4-2.6), P<0.001, aches AHR = 2.1 ((95%CI = 1.5-2.9), P<0.001, and fatigue AHR = 1.5 ((95%CI = 1.3-1.7), P<0.001.DISCUSSION:Overall, the present study suggests that neurological signs of dengue are not exceptional even in patients without the most severe features of dengue. These manifestations were spontaneously resolutive. Here it was not possible to distinguish between encephalitis or encephalopathy. Further studies would require more in depth exploration of the patients.

Background: The objective of the study was to determine the incidence of transaminase elevation during dengue, and its predictive factors. Methods: In 2013, a longitudinal study was performed using data from all cases of dengue seen in Cayenne Hospital. Cox proportional modeling was used. Signs of major transaminase elevation were defined as an increase in aspartate amino transferase (AST) or alanine amino transferase (ALT) concentration over 10 times the normal value (10N). Results: There were 1574 patients and 13 249 person-days of follow-up. The incidence rate for signs of trans-aminase elevation (10N) was 0.55 per 100 person-days. Six patients had major transaminase elevation with AST.1000 units (0.43 per 1000 patient-days), and 73 patients (4.6%) developed transaminase elevation with AST .10N. The variables independently associated with major transaminase elevation were hyponatremia, low platelets, dehydration, hematocrit increase, food intolerance, positive nonstructural protein 1 (NS1), age over 15 years and the notion of paracetamol intake. Conclusions: Although very frequent, the incidence of major transaminase elevation was lower than reported elsewhere perhaps because of good access to care, or of the particular serotype causing this epidemic. The patients with transaminase elevation tended to be older, more severe and taking paracetamol.

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.

Résumé :Introduction : Les départements Français d’Amérique sont à la fois parmi les territoiresfrançais les plus affectés par le VIH et parmi les territoires français les plus impactés par laconsommation de crack. L’épidémie de VIH en Guyane est une épidémie concentrée quitouche plus spécifiquement certains groupes vulnérables. Parmi ces groupes, les usagers decrack sont particulièrement touchés.Matériel et Méthodes : Une étude a été réalisée simultanément dans les trois départements en2012 dans le but de décrire les connaissances, les attitudes et les pratiques vis-à-vis du VIH etdes IST chez les usagers de crack. Au total 640 personnes ont été interrogées. La méthoded’échantillonnage utilisée était non probabiliste et combinait un échantillonnage deconvenance dans les associations recevant ce public (75% de l’échantillon), et unéchantillonnage en boule de neige en dehors afin d’atteindre les personnes ne fréquentant pasles structures (25% de l’échantillon).Résultats : Un tiers des personnes n’utilisait pas systématiquement le préservatif avec lespartenaires occasionnels (36,2%) ou avec les partenaires commerciaux (32,3%), et 64%n’utilisaient pas le préservatif à chaque fois avec les partenaires réguliers. Différents facteursprédictifs de la non utilisation du préservatif ont été identifiés selon le type de partenaire àl’aide d’un modèle log-binomial. Parmi les différents facteurs repérés, deux étaient communsà chaque type de partenaire : la perception élevée de son risque face au VIH et le fait de nepas se sentir à l’aise pour persuader un partenaire à utiliser le préservatif.Discussion : Dans un contexte de multipartenariat, de violences sexuelles fréquentes et dedépistage insuffisant du VIH, la non utilisation systématique du préservatif peut avoir unimpact non négligeable dans la diffusion de l’épidémie. Bien que la non utilisation dupréservatif soit sensiblement inférieure à ce que l’on retrouve dans la littérature, cesproportions traduisent un réel problème.La capacité à persuader un partenaire sexuel à utiliser un préservatif était négativementcorrélée avec la non utilisation du préservatif quel que soit le type de partenaire. Ainsi, ilsemble que lorsque les personnes se sentaient capables de négocier l'utilisation du préservatif,elles l’utilisaient de manière plus systématique. La capacité personnelle perçue est souventconsidérée comme un levier important pour adapter les comportements de santé. Or, elle peutêtre affectée dans des situations de stigmatisation, d’addiction ou de relation violente. Cesrésultats soulignent l’importance d’interventions spécifiques de prévention parmi les usagersde crack et notamment des interventions visant à améliorer le sentiment d’efficacitépersonnelle (perceived self-efficacy) et d’estime de soi.

Résumé : International audience
Cytomegalovirus (CMV) infection is common among HIV-infected patients but its repercussion on the course of CD4+ and CD8+ T cells after cART initiation remains elusive. The French Dat'AIDS cohort enrolled 5,688 patients on first-line cART, from which we selected patients who achieved HIV suppression for at least 12 months without modification of cART, and for whom CMV serostatus was available. Five hundred and three patients fulfilled the selection criteria (74% male, median age 43 yrs, 15.5% CDC stage C), of whom 444 (88.3%) were seropositive for CMV (CMV+). Multivariate analyses using mixed-linear models adjusted for the time from HIV suppression, sex, age, transmission risk group, duration of HIV follow-up, the interaction between time from HIV suppression and CMV+ serol-ogy, and the nadir CD4 count revealed a negative correlation between CMV+ and CD4: CD8 ratio (coeff. =-0.16; p = 0.001). This correlation was also observed among patients displaying optimal CD4 recovery (!500 cells/mm3 at M12; coeff. =-0.24; p = 0.002). Hence, CMV+ serostatus antagonizes normalization of the CD4:CD8 ratio, although further analyses of the impact of co-morbidities that associate with CMV serostatus, like HCV infection, are needed to elucidate this antagonism formally. However, this might reflect a premature T cell senescence, thus advocating for a close monitoring of T cells in CMV co-infected patients. In addition, our results raise the question of the benefit of treatment for asymptomatic CMV co-infection in HIV-infected patients.

Résumé : International audience
Infective endocarditis is defined by a focus of infection within the heart and is a feared disease across the field of cardiology. It is frequently acquired in the health care setting, and more than one-half of cases now occur in patients without known heart disease. Despite optimal care, mortality approaches 30% at 1 year. The challenges posed by infective endocarditis are significant. It is heterogeneous in etiology, clinical manifestations, and course. Staphylococcus aureus, which has become the predominant causative organism in the developed world, leads to an aggressive form of the disease, often in vulnerable or elderly patient populations. There is a lack of research infrastructure and funding, with few randomized controlled trials to guide practice. Longstanding controversies such as the timing of surgery or the role of antibiotic prophylaxis have not been resolved. The present article reviews the challenges posed by infective endocarditis and outlines current and future strategies to limit its impact. (C) 2017 by the American College of Cardiology Foundation.

Résumé : International audience
The French Antilles (Martinique, Saint Martin and Guadeloupe) and French Guiana are the French territories most affected by the HIV epidemic. Some population groups such as men who have sex with men (MSM), especially those involved in transactional sex, are thought to be particularly vulnerable to HIV but few data exist to help characterize their health-related needs and thus implement relevant prevention interventions. To fill this knowledge gap, we used data collected from an HIV/AIDS Knowledge, Attitudes, Behaviours and Practices survey conducted in 2012 among MSM living in the French Antilles and French Guiana and recruited through snowball sampling. Our objectives were to compare social and demographic characteristics and sexual behaviours between MSM engaging in transactional sex and MSM not engaging in transactional sex and to identify factors associated with transactional sex involvement using a logistic regression model. A total of 733 MSM were interviewed, 21% of whom reported to undergo transactional sex. Their behaviour and social and demographic characteristics were different from other MSMs’ and they were more exposed to factors that are recognized to potentiate HIVvulnerability, at the individual, community, network and structural levels. The variables positively associated with sex trade involvement were having ever consumed drug (OR = 2.84 [1.23–6.52]; p = .002), having a greater number of sex partners than the median (OR = 8.31 [4.84–14.30]; p < .001), having experienced intimate partner violence (OR = 1.72 [0.99–3.00]; p = .053) and having undergone physical aggression because of sexual orientation (OR = 2.84 [1.23–6.52];p = .014). Variables negatively associated with sex trade involvement were being older (OR = 0.93 [0.90–0.97] per year; p = .001), having a stable administrative situation (OR = 0.10 [0.06–0.19]; p < .001), having a stable housing (OR = 0.29 [0.15–0.55]; p < .001) and being employed full-time (OR = 0.29 [1.23–6.52]; p = .002).

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.

Résumé : International audience
Anti-leishmaniasis drug resistance is a common problem worldwide. The aim of this study was to inventory the general in vitro level of sensitivity of Leishmania isolates circulating in French Guiana and to highlight potential in vitro pentamidine-resistant isolates. This sensitivity study was conducted on 36 patient-promastigote isolates for seven drugs (amphotericin B, azithromycin, fluconazole, meglumine antimoniate, miltefosine, paromomycin, and pentamidine) using the Cell Counting Kit-8 viability test. The IC50 values obtained were heterogeneous. One isolate exhibited high IC50 values for almost all drugs tested. Pentamidine, which is the first-line treatment in French Guiana, showed efficacy at very low doses (mean of 0.0038 μg/mL). The concordance of the in vitro pentamidine results with the patients' clinical outcomes was 94% (K = 0.82).

Résumé : International audience
AIMS: Indications for surgery in acute infective endocarditis (IE) are detailed in guidelines, but their application is not well known. We analysed the agreement between the patient's attending physicians and European Society of Cardiology guidelines regarding indications for surgery. We also assessed whether surgery was performed in patients who had an indication. METHODS AND RESULTS: From the 2008 prospective population-based French survey on IE, 303 patients with definite left-sided native IE were identified. For each case, we prospectively recorded (i) indication for surgery according to the attending physicians and (ii) indication for surgery according to guidelines. Surgery was indicated in 194 (65%) patients according to attending physicians and in 221 (73%) according to guidelines, while 139 (46%) underwent surgery. Agreement was moderate between attending physicians and guidelines (kappa 0.41-0.59) and between indication according to guidelines and the performance of surgery (kappa 0.38). Of the 90 (30%) patients not operated despite indication, contraindication to surgery was reported by the attending physicians in 42 (47%), and indication was not identified in 48 (53%). One-year survival was 76% in patients with indication and surgery performed (n = 131), 69% in patients without indication and no surgery (n = 74), 56% in patients with identified indication and contraindication to surgery (n = 42), and 60% in patients with no identified indication (n = 48; P = 0.059). CONCLUSION: Cardiac surgery during acute IE was recommended in almost three out of four patients, although fewer than half were actually operated.

Résumé : International audience
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.

Résumé : International audience
Zika fever is an Aedes-borne disease caused by a flavivirus (Zika virus, ZIKV, genus Flavivirus). During the past years ZIKV spread in Polynesia, South-America and the Caribbean. Most ZIKV infections are asymptomatic or result in mild febrile disease with rash and conjunctivitis. Attention was recently drawn to non-vectored ZIKV transmission, including sexual, probable blood-borne and mother-to-fetus transmission, and to severe forms such as Guillain-Barré syndrome, acute neurological infections and fetal abnormalities (including microcephaly). Many aspects of Zika fever natural history remain unknown, e.g. the proportion of asymptomatic cases and the duration of viremia. Estimating the prevalence of Zika infections is difficult because a large proportion of infected individuals do not seek medical attention and seroprevalence studies are hampered by antigenic cross-reactivity with other flaviviruses, e.g. dengue virus. Here, we present a study of ZIKV infection in blooddonors from Martinique island (French West Indies, Caribbean region), with novel epidemiological, biological and clinical information that refine the picture of Zika fever in adults.

Résumé : National audience
Introduction Depuis le début de l’ère des traitements antirétroviraux hautement actifs, les patients vivant avec le VIH (PVVIH) vieillissent. Les comorbidités liées à l’âge (CLA) deviennent des causes grandissantes de mortalité dans cette population.L’objectif de cette étude était d’évaluer leur impact sur la surmortalité liée au VIH sur 5 ans chez les PVVIH âgés de 60 ans ou plus suivis dans le cadre d’une large cohorte prospective multicentrique française (Dat’AIDS) à l’ère tardive des antirétroviraux hautement actifs (du 01/01/2008 au 31/12/2012).

Résumé : International audience
The prognosis of vertebral alveolar echinococcosis (AE) is poor. We report on the unique outcome of a patient with preexisting liver cirrhosis, in whom a diagnosis of vertebral AE was established on vertebral histopathology (D4 corporectomy in 2010 for paraplegia). Therapeutic drug monitoring of albendazole (ABZ) showed that a low dosage was appropriate. The patient recovered and ABZ withdrawal was decided in 2014, with no relapse 18 months later. In this patient, infection was purely or mainly localized in the dorsal spine, and this may have been favored by liver cirrhosis. A longer follow-up is, however, needed to confirm cure.
