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
OBJECTIVE: We hypothesized that, in Human Immunodeficiency Virus and Hepatitis C Virus (HIV/HCV) co-infected patients who did not respond to peg-interferon and ribavirin, a maintenance therapy with peg-interferon could induce fibrosis regression. METHODS: This was a randomized study with two parallel groups. HIV/HCV co-infected patients received peg-interferon α-2a at 180 μg/week or remained on observation for 96 weeks. The primary endpoint was the percentage of patients who experienced a decrease of at least one point in their Metavir fibrosis score between initial and final liver biopsies. Secondary endpoints included plasma fibrosis markers at week 96, occurrence of HCV-related complications, and survival. RESULTS: A total of 52 patients were randomized (peg-interferon: 25; control: 27) including 18 with cirrhosis. The median (interquartile range) age was 44 (40-46) years, and 69% were male. A total of 64% had ALT levels >1.5 normal values, and the CD4 cell count was 391 (296-537) cells/mm(3); 67% of patients had HIV RNA <200 copies/mL at entry. The main endpoint was assessed in 41 patients. Response rates were 3/20 (15%) and 4/21 (19%) in the peg-interferon and control groups, respectively (p = 0.99). There was no significant difference between peg-interferon and control groups on plasma fibrosis markers at the final visit. Severe liver-related complications were observed in 2 and 5 patients in peg-interferon and control groups, respectively. Three deaths were observed, all in the control group. CONCLUSIONS: A maintenance therapy with peg-interferon α-2a over 96 weeks in HIV/HCV co-infected patients, who were non-responders to HCV treatment, did not change liver fibrosis.

Résumé : International audience
BACKGROUND: Chronic HCV infection is associated with the development of hepatic fibrosis. The direct role of HCV in the fibrogenic process is unknown. Specifically, whether HCV is able to infect hepatic stellate cells (HSCs) is debated. OBJECTIVE: To assess whether human HSCs are susceptible to HCV infection. DESIGN: We combined a set of original HCV models, including the infectious genotype 2a JFH1 model (HCVcc), retroviral pseudoparticles expressing the folded HCV genotype 1b envelope glycoproteins (HCVpp) and a subgenomic genotype 1b HCV replicon, and two relevant cellular models, primary human HSCs from different patients and the LX-2 cell line, to assess whether HCV can infect/replicate in HSCs. RESULTS: In contrast with the hepatocyte cell line Huh-7, neither infectious HCVcc nor HCVpp infected primary human HSCs or LX-2 cells. The cellular expression of host cellular factors required for HCV entry was high in Huh-7 cells but low in HSCs and LX-2 cells, with the exception of CD81. Finally, replication of a genotype 2a full-length RNA genome and a genotype 1b subgenomic replicon was impaired in primary human HSCs and LX-2 cells, which expressed low levels of cellular factors known to play a key role in the HCV life-cycle, suggesting that human HSCs are not permissive for HCV replication. CONCLUSIONS: Human HSCs are refractory to HCV infection. Both HCV entry and replication are deficient in these cells, regardless of the HCV genotype and origin of the cells. Thus, HCV infection of HSCs does not play a role in liver fibrosis. These results do not rule out a direct role of HCV infection of hepatocytes in the fibrogenic process.

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
The most recent data on prevalence of chronic hepatitis B and C in the French Overseas Territories (FOT) show great variability among these territories with a prevalence rising from 0.46 to 3.4% for HBs Antigen and from 0.02 to 0.67%for anti HCV antibodies. The modes of transmission rely mainly for HBV on sexual or materno-fetal exposure, especially among people from non-French border endemic areas, and for HCV on blood or nosocomial route. Good adhesion of the treating physicians and pediatricians to vaccination has significantly reduced the prevalence of HBV in the ten past years, with an estimated coverage of 75 to 85%depending on the territories. Although there is still a high prevalence of HBV in some FOT, the screening policy and management are based on those carried out inmetropolitan France, which seems insufficient and inadequate to the situation of these territories. Regarding the therapeutic management of HCV, the means attributed to FOT have been identical to those of metropolitan France but the small number of specialist practitioners and remoteness contributed to provision of new molecules later in certain territories. Medical pluridisciplinary sessions have been implemented and based on the universitary or regional hospitals. Copyright © 2017 John Libbey Eurotext.

Résumé : International audience
The non-classical human leukocyte antigen-G, HLA-G, plays an important role in inducing tolerance, through its immunosuppressive effects on all types of immune cells. Immune tolerance is a key issue in the liver, both in liver homeostasis and in the response to liver injury or cancer. It would therefore appear likely that HLA-G plays an important role in liver diseases. Indeed, this molecule was recently shown to be produced by mast cells in the livers of patients infected with hepatitis C virus (HCV). Furthermore, the number of HLA-G-positive mast cells was significantly associated with fibrosis progression. The generation of immune tolerance is a role common to both HLA-G, as a molecule, and the liver, as an organ. This review provides a summary of the evidence implicating HLA-G in liver diseases. In the normal liver, HLA-G transcripts can be detected, but there is no HLA-G protein. However, HLA-G protein is detectable in the liver tissues and/or plasma of patients suffering from hepatocellular carcinoma, hepatitis B or C, or visceral leishmaniasis and in liver transplant recipients. The cells responsible for producing HLA-G differ between diseases. HLA-G expression is probably induced by microenvironmental factors, such as cytokines. The expression of HLA-G receptors, such as ILT2, ILT4, and KIRD2L4, on liver cells has yet to be investigated, but these receptors have been detected on all types of immune cells, and such cells are present in liver. The tolerogenic properties of HLA-G explain its deleterious effects in cancers and its beneficial effects in transplantation. Given the key role of HLA-G in immune tolerance, new therapeutic agents targeting HLA-G could be tested for the treatment of these diseases in the future.

Résumé : Hepatitis C virus (HCV) is one of the leading causes of hepatocellular carcinoma. Therapeutic treatment against the virus has been recently improved by a tritherapy including pegylated interferon, ribavirin and antiviral protease. Nevertheless, the importance of side effects and the emergence of resistant mutants require the development of new antivirals. In this context, our team has recently discovered that Type III phosphatidylinositol 4-kinases (PI4KIIIα and PI4KIIIβ) are essential for the propagation of the virus in a human hepatic cell line at the entry and replication steps. To further characterize these potential therapeutic targets, we investigate the implication of these kinases during the HCV entry, using primary human hepatocytes, a model closer to the in vivo conditions. Two lines of research were developed: Verification of the importance of the kinase activity of PI4KIIIs during HCV entry in primary human hepatocytes, through a chemical approach; Validation of the involvement of these kinases and their enzymatic activity during viral entry through a genetic approach based on RNA interference and phenotype rescue. In parallel, we studied the expression of PI4KIIIα in liver diseases. Our results suggest the involvement of PI4KIIIα in HCV entry; the involvement of PI4KIIIIβ needs to be confirmed. The analysis of PI4KIIIα expression in hepatocellular carcinoma led us to propose this kinase as a new molecular marker, which could improve the already established prognosis models and could lead to the development of new therapeutic approaches.
Le virus de l’hépatite C (VHC) est l’un des principaux facteurs étiologiques du carcinome hépatocellulaire. Le traitement des hépatites virales C a été récemment amélioré grâce à une trithérapie (interféron, ribavirine et anti-protéase virale). Néanmoins l’importance des effets secondaires et l’émergence de mutants résistants nécessitent de découvrir de nouveaux antiviraux. Dans ce contexte, notre équipe a récemment découvert que les phosphatidylinositol 4-kinases de type III (PI4KIIIα et PI4KIIIβ) étaient indispensables à la propagation du virus dans une lignée hépatique humaine, et ce, à 2 étapes de son cycle biologique : l’entrée et la réplication. L’objectif du présent travail était de poursuivre la validation de ces nouvelles cibles thérapeutiques potentielles, en approfondissant nos connaissances sur la dépendance du virus à l’égard de ces kinases au cours de son entrée. Pour cela, nous avons utilisé le modèle des hépatocytes humains primaires, système in vitro plus proche du contexte physiologique que les modèles utilisés jusqu’à présent et qui étaient basés sur l’exploitation de lignées. Deux axes ont été développés : Vérification de l’importance de l’activité kinase des PI4KIIIs au cours de l’entrée du VHC dans les hépatocytes humains primaires, à travers une approche chimique ; Validation de l’implication de ces kinases et de leur activité enzymatique au cours de l’entrée virale grâce à une approche génétique basée sur l’ARN interférence et la restauration de phénotype. En parallèle, nous avons étudié l’expression de PI4KIIIα au cours de pathologies hépatiques. Nos résultats suggèrent une implication de PI4KIIIα au cours de l’entrée du VHC dans les hépatocytes humains primaires, mais restent à confirmer quant à l’implication de PI4KIIIβ. Par ailleurs, l’analyse de l’expression de PI4KIIIα dans le carcinome hépatocellulaire (CHC) conduit à proposer cette kinase comme un nouveau marqueur moléculaire, qui pourrait améliorer les modèles de pronostic déjà établis et pourrait conduire au développement de nouvelles approches thérapeutiques pour les patients atteints d’un CHC, quelque soit l’étiologie.

Résumé : International audience
A thorough phytochemical study of Stereocaulon evolutum was conducted, for the isolation of structurally related atranorin derivatives. Indeed, pilot experiments suggested that atra-norin (1), the main metabolite of this lichen, would interfere with the lifecycle of hepatitis C virus (HCV). Eight compounds, including one reported for the first time (2), were isolated and characterized. Two analogs (5, 6) were also synthesized, to enlarge the panel of atra-norin-related structures. Most of these compounds were active against HCV, with a half-maximal inhibitory concentration of about 10 to 70 µM, with depsides more potent than monoaromatic phenols. The most effective inhibitors (1, 5 and 6) were then added at different steps of the HCV lifecycle. Interestingly, atranorin (1), bearing an aldehyde function at C-3, inhibited only viral entry, whereas the synthetic compounds 5 and 6, bearing a hydroxy-methyl and a methyl function, respectively, at C-3 interfered with viral replication.

Résumé : International audience
To assess prognostic factors for survival and describe Model for End-Stage liver disease (MELD) dynamics in human immunodeficiency virus+/hepatitis C virus+ (HIV+/HCV+) patients after an initial episode of hepatic decompensation.An HIV+/HCV+ cohort of patients experiencing an initial decompensation episode within the year preceding enrollment were followed prospectively. Clinical and biological data were collected every 3 months. Predictors for survival were identified using Kaplan-Meier curves and Cox models. A 2-slope-mixed linear model was used to estimate MELD score changes as a function of survival.Sixty seven patients were included in 32 centers between 2009 and 2012 (72% male; median age: 48 years [interquartile ratio (IQR):45-52], median follow-up: 22.4 months [range: 0.5-65.3]). Overall survival rates were 86%, 78%, and 59% at 6, 12, and 24 months, respectively. Under multivariate analysis, the MELD score at initial decompensation was predictive of survival, adjusted for age, type of decompensation, baseline CD4 counts, and further decompensation during follow-up as a time-dependent variable. The adjusted hazard ratio of death was 1.32 for a score 3 points higher (95% CI: [1.06-1.63], P = 0.012). MELD score kinetics within the 6 months after initial decompensation differed significantly between non-deceased and deceased patients, with a decreased (-0.49/month; P = 0.016), versus a flat (+0.06/month, P = 0.753) mean change in score.MELD is an effective tool to predict survival in HIV+/HCV+ patients with decompensated cirrhosis. A non-decreasing MELD score within 6 months following this initial decompensation episode may benefit from privileged access to liver transplantation in this poor prognosis population

Résumé : International audience
BACKGROUND AND AIMS: Infection by hepatitis C virus is a worldwide health problem. An inadequate Th2 cytokine response promotes the fibrosis-cirrhosis fate. Immune-modulating molecules favoring a Th2 profile, such as HLA-G molecules of the HLA class Ib family, may play a role in chronic hepatitis. HLA-G contributes to the escape of tumors, and their involvement in viral infections has been increasingly described. The aim of this work was to study the expression of HLA-G in the liver, its cellular source and its regulation in cases of chronic C hepatitis. METHODS: HLA-G cells in blocks of liver derived from patients infected with HCV were labeled by immunohistochemistry and enumerated. Double immunofluorescence allowed the identification of the cellular source. HLA-G secretion by a human mast cell line was quantified by ELISA after various stimulations. After treatment with IFN-α real-time PCR was performed to determine the kinetics of cytokine expression profiles, followed by heat map clustering analysis. RESULTS: The number of HLA-G + cells was significantly associated with the area of fibrosis. For the first time, we identify the HLA-G+ cells as being mast cells. HLA-G secretion was significantly induced in human mast cells stimulated by IL-10 or interferons of class I. The transcriptome of the secretome of this cell line stimulated by IFN-α revealed that i) the HLA-G gene is upregulated late, ii) T lymphocytes and NK cells are recruited. CONCLUSIONS: These findings suggest an autocrine loop in the genesis of HCV liver fibrosis, based on mast cells expressing HLA-G.

Résumé : National audience
Il virus dell’epatite C (HCV), a trasmissione parenterale, è stato identificato nel 1989 come il virus responsabile delle epatiti «non A non B». L’infezione colpisce circa 170 milioni di persone nel mondo e 200 000 persone in Francia hanno una replicazione virale attiva. Nei paesi industrializzati, l’epidemia ha accompagnato lo sviluppo della trasfusione sanguigna e della tossicomania endovenosa. I test enzyme-linked immunosorbent assay che individuano gli anticorpi anti-HCV hanno permesso uno screening attendibile dell’infezione a partire dal 1992. La rilevazione dell’acido ribonucleico virale C permette la diagnosi dell’infezione cronica che fa seguito all’epatite acuta in circa l’80% dei casi. La gravità dell’infezione è legata allo sviluppo progressivo di una fibrosi epatica che conduce alla cirrosi dopo una mediana di evoluzione di 30-40 anni. La malattia è, così, responsabile di circa 350 000 decessi per anno nel mondo, legati, in parti uguali, all’insufficienza epatica e al carcinoma epatocellulare. Il trattamento ha compiuto enormi progressi in 20 anni e nuove molecole antivirali sono in corso di sviluppo clinico.

Résumé : International audience
The aim of this study was to determine factors associated with complete satisfaction with the care provided (satisfaction with physicians and satisfaction with services and organization) among HIV-infected patients followed up in the French ANRS CO8 APROCO-COPILOTE cohort. Analyses focused on cross-sectional data collected during the ninth year of cohort follow-up. Satisfaction with care, sociodemographic characteristics, and behavioral data were collected using self-administered questionnaires, while clinical data were derived from medical records. Complete satisfaction with care was defined as being 100% satisfied. Two logistic regression models were used to identify predictors of (1) complete satisfaction with physicians (n=404) and (2) complete satisfaction with services and organization (n=396). Sixteen percent of patients were completely satisfied with physicians, while 15.9% were completely satisfied with services and organization. Being older and reporting fewer discomforting antiretroviral therapy (ART) side effects were factors independently associated with complete satisfaction with both physicians and services and organization. Strong support from friends and absence of hepatitis C (HCV) co-infection were independently associated with complete satisfaction with physicians, while strong support from one's family and comfortable housing conditions were independently associated with complete satisfaction with services and organization. Even after nine years of follow-up, social vulnerabilities still strongly influence HIV-infected patients' interactions with the health care system. Day-to-day experience with the disease, including perceived treatment side effects, appears to play a key role in the quality of these interactions. More attention should be given to patient satisfaction, especially for socially vulnerable patients, in order to avoid potentially detrimental consequences such as poor adherence to ART.

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.
