Résumé : International audience
Retreatment with pegylated interferon (peg-IFN) and ribavirin (RBV) results in poor sustained virological response (SVR) rates in human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients. There are limited data regarding the use of telaprevir plus peg-IFN/RBV in this population. HIV type 1-infected patients who previously failed ≥12 weeks of peg-IFN/RBV for HCV genotype 1 coinfection were enrolled in a single-arm, phase 2 trial. Patients with cirrhosis and previous null response were excluded. Authorized antiretrovirals were tenofovir, emtricitabine, efavirenz, atazanavir, and raltegravir. All patients received peg-IFN alfa-2a (180 µg/week) plus RBV (1000-1200 mg/day) for 4 weeks, followed by telaprevir (750 mg or 1125 mg every 8 hours with efavirenz) plus peg-IFN/RBV for 12 weeks and peg-IFN/RBV for 32-56 weeks according to virological response at week 8. The primary endpoint was the SVR rate at 24 weeks after the end of treatment (SVR24). Sixty-nine patients started treatment; SVR24 was achieved in 55 (80% [95% confidence interval, 68%-88%). SVR24 was not influenced by baseline fibrosis stage, IL28B genotype, antiretroviral regimen, HCV subtype, CD4 cell count, previous response to HCV treatment, HCV RNA level, or HCV RNA decline at week 4. HCV treatment was discontinued for adverse events (AEs) in 20% of patients, including cutaneous (4%), psychiatric (4%), hematological (6%), and other AEs (6%). Peg-IFN or RBV dose reduction was required in 23% and 43% of patients, respectively. Seventy percent of patients required erythropoietin, blood transfusions, or RBV dose reduction for anemia. Two patients died during the study. No HIV breakthrough was observed. Despite a high discontinuation rate related to toxicity, a substantial proportion of treatment-experienced HIV-coinfected patients achieved SVR24 with a telaprevir-based regimen.

Résumé : National audience
Started in 2015 in Brazil, an outbreak linked to a little known arbovirus, Zika virus spread throughout Latin America. This virus, considered until recently as responsible of only mild symptoms, made mention of previously unsuspected complications, with severe neurological manifestations in adults and malformations of the central nervous system, including microcephaly, in newborns of mother infected during the pregnancy. While the continent is more accustomed to the succession of arbovirus epidemics, suspected complications and the many unknowns keys of the latter arriving raise many public health issues. French Guiana, a French territory located in the north-east of the continent, combines both European level of resources and climate and issues specific to the Amazon region and Latin America. We discuss here the issues for 2016 Zika virus epidemic in our region, many of them are generalizable to neighboring countries.

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
BACKGROUND: A prospective study of infectious encephalitis was conducted in France in 2007. In total, 253 patients were enrolled with a proven etiological diagnosis for 52%. The cohort of surviving patients with encephalitis was assessed for sequelae and impairment 3 years after enrollment. METHODS: Patients, their family, and general practitioners (GPs) were interviewed by phone to document persisting symptoms, return to work, and past and current leisure activities, with standardized questionnaires. The IQCODE (Informant Questionnaire on Cognitive Decline in the Elderly) was completed with relatives. The global outcome was determined in all patients with the Glasgow outcome scale. RESULTS: In 2010, 20 patients (10%) were unavailable for follow-up, 2 (1%) were excluded, and 18 (9%) had died since hospital discharge. Data were available for 167 survivors and 9 patients whose death was related to the encephalitis. The outcome was favorable in 108 of 176 patients (61%) (71 with complete resolution), 31 (18%) were mildly impaired, 25 (14%) were severely impaired, and 3 (1%) were in a vegetative state. The most frequent symptoms were difficulty concentrating (42%), behavioral disorders (27%), speech disorders (20%), and memory loss (19%). Fifteen of 63 patients (24%) previously employed were still unable to resume work. Long-term outcome was significantly associated with comorbid conditions, age, level of education, and the causative agent of encephalitis. CONCLUSIONS: Most patients with encephalitis experienced a favorable outcome 3 years after hospital discharge. However, minor to severe disability persists in a high number of cases with consequences for everyday life. Physical and mental impairment should be evaluated in all patients with encephalitis, and neuropsychological rehabilitation implemented whenever needed.

Résumé : International audience
The CoPanFlu-France cohort of households was set up in 2009 to study the risk factors for infection by the pandemic influenza virus (H1N1pdm) in the French general population. The authors developed an integrative data-driven approach to identify individual, collective and environmental factors associated with the post-seasonal serological H1N1pdm geometric mean titer, and derived a nested case-control analysis to identify risk factors for infection during the first season. This analysis included 1377 subjects (601 households). The GMT for the general population was 47.1 (95% confidence interval (CI): 45.1, 49.2). According to a multivariable analysis, pandemic vaccination, seasonal vaccination in 2009, recent history of influenza-like illness, asthma, chronic obstructive pulmonary disease, social contacts at school and use of public transports by the local population were associated with a higher GMT, whereas history of smoking was associated with a lower GMT. Additionally, young age at inclusion and risk perception of exposure to the virus at work were identified as possible risk factors, whereas presence of an air humidifier in the living room was a possible protective factor. These findings will be interpreted in light of the longitudinal analyses of this ongoing cohort.

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
BACKGROUND: Human immunodeficiency virus (HIV)-infected patients have decreased immune response to vaccines. Few data are available about pandemic flu vaccination in this population. METHODS: We conducted a multicenter, patient-blinded, randomized trial in a cohort of HIV-infected adults. Patients received 2 injections 21 days apart of a AS03(A)-adjuvanted H1N1v vaccine containing 3.75 μg hemagglutinin (HA) or a nonadjuvanted H1N1v vaccine containing 15 μg HA to assess hemagglutination inhibition (HI) response and safety. RESULTS: A total of 309 patients were randomized, and 306 were vaccinated. After the first vaccine dose, HI titers ≥1:40 were observed in 93.4% of the patients in the adjuvanted group (A group) (n = 155) and in 75.5% in the nonadjuvanted group (B group) (n = 151) (P < .001); seroconversion rates were 88.8% and 71.2%, and factor increases in geometric mean titers (GMT) of 21.9 and 15.1, respectively. After 2 injections, 98.6% of patients of the A group and 92.1% of the B group demonstrated HI titers ≥1:40 (P = .018); seroconversion rates were 96.5% and 87.1%, respectively, and factor increases in GMT were 45.5 and 21.2, respectively. The majority of adverse events were mild to moderate in severity; no impact on CD4+ cell count or viral load has been detected. CONCLUSIONS: In HIV-1-infected adults, the AS03(A)-adjuvanted H1N1v vaccine yielded a higher immune response than did the nonadjuvanted one, with no impact on HIV infection.

Résumé : National audience
Introduction-objectifsBien que la prise en charge de personnes vivant avec le VIH (PVVIH) s’améliore globalement en Guyane, les disparités régionales et communautaires restent importantes. L’objectif est ici de décrire pour la première fois les caractéristiques épidémiologiques, spatiales et cliniques des PVVIH suivies en zones isolées. Matériels et MéthodesLes données présentées sont issues du suivi clinique réalisé en Centres Délocalisés de Prévention et de Soins (CDPS) de janvier 2014 à novembre 2015. Ces données ont été analysées et comparées aux données des PVVIH suivis dans les 3 centres hospitaliers de Guyane issues du logiciel Nadis®.Résultats 174 PVVIH ont étés pris en charge en CDPS et comparés à 2143 patients suivis sur le littoral. L’évolution du taux annuel de découvertes de séropositivité VIH montre une arrivée plus tardive mais particulièrement active en zones isolées par rapport au littoral, notamment chez les patients d’origine brésilienne (p<0,005). L’âge médian est de 43,8 ans, le sex ratio homme/femme est de 0,98. En zone isolées comme sur le littoral 1/3 des PVVIH sont dépistés tardivement (<200 CD4/mm3). Le succès virologiques après 6 mois de traitement est de 80% vs 88% sur le littoral (p=0,135), la moyenne des derniers CD4 (424 vs 569/mm3) est plus basse que sur le littoral (p<0,005) enfin la charge virale moyenne est plus élevée que sur le littoral (8960 vs 5317 copies /mL) (p<0,005). L’histoplasmose est la première cause d’infection opportuniste retrouvée. La répartition spatiale des patients suivis montre une incidence et prévalence de cas particulièrement élevée dans les villes frontalières charnières que constituent Maripasoula et Saint Georges de l’Oyapock. ConclusionLe caractère particulièrement actif et original de l’épidémie et les indicateurs de suivi moins bons que sur le littoral rappellent l’importance de compléter les moyens de la prise en charge des PVVIH en zones isolées en Guyane.

Résumé : International audience
Objective: To describe characteristics and outcomes of HIV-infected patients with Pneumocystis jirovecii pneumonia (PCP) over 2004–2011 in France, in particular in those previously enrolled (PE) in the French Hospital Database on HIV (FHDH). Methods: PE patients with an incident PCP were compared with patients with an inaugural PCP revealing HIV infection (reference). Adequate adherence to care was defined as a CD4 measurement at least every 6 months. Immune reconstitution (CD4$200/mm 3) and risk of death were studied using Kaplan-Meier estimates and multivariable Cox proportional hazards models. Results: In a context of a decreasing incidence of PCP, 1259 HIV-infected patients had a PCP diagnosis, and 593 (47%) were PE patients of whom 161 (27%) have had a prior history of AIDS-defining clinical illness (prior ADI). Median time since enrolment was 8 years for PE patients; 74% had received cART. Median proportion of time with adequate adherence to care was 85% (IQR, 66–96) for all FHDH enrollees, but only 45% (IQR, 1–81) for PE patients during the 2 years before PCP. Median CD4 cell count (38/mm 3) and HIV viral load (5.2 log10 copies/ml) at PCP diagnosis did not differ between PE patients and the reference group. Three year mortality rate of 25% was observed for PE prior ADI group, higher than in PE non-prior ADI group (8%) and the reference group (9%) (p,0.0001). In the PE prior ADI group, poor prognosis remained even after adjustment for virological control and immune reconstitution (HR, 2.4 [95%CI, 1.5–3.7]). Conclusion: Almost 50% of PCP diagnoses in HIV-infected patients occurred presently in patients already in care, mainly with a previous cART prescription but with waning adherence to care. Having repeated ADI is contributing to the risk of death beyond its impact on immune reconstitution and viral suppression: special efforts must be undertaken to maintain those patients in care.

Résumé : International audience
Febrile illness is a common cause of attendance at emergency departments. The purpose of this study was to describe infectious aetiologies of fever in a tropical setting. We prospectively included 1443 febrile patients, all French Guiana residents, who presented at Cayenne Hospital emergency department. This report will propose an overview of aetiologies of febrile illness in French Guiana, and tropical diseases such as malaria and arbovirus infections are discussed. Almost 30% of fevers remained unexplained. Further prospective multicentre studies are warranted to improve the diagnosis of overlooked pathogens in French Guiana. Such studies would lead to conclusions of specific interest in the travel medicine field.
