Which antiretrovirals should be prescribed as first-line treatments? Changes over the past 10 years in France

International audienceOBJECTIVE:To describe the changes in first-line antiretroviral (ART) regimens in France between 2005 and 2015 and patients' characteristics related to the use of protease inhibitors in 2015.METHODS:We extracted all patients starting ART between 2005 and 2015 from a large prospective cohort. Regimens were classified as three nucleoside reverse transcriptase inhibitors (NRTI), or two NRTIs with a boosted protease inhibitor (bPI), with a non-nucleoside reverse transcriptase inhibitor (NNRTI), or with an INSTI. Patients' characteristics at the time of initiation were collected. A multinomial logit model was fitted to analyze characteristics related to the choice of regimen in 2015.RESULTS:We analyzed data from 15,897 patients. The proportion of patients starting with (i) a bPI decreased from 60% before 2014 to 38.1% in 2015; (ii) an NNRTI decreased from 30% to 17.8% in 2015; (iii) an INSTI gradually increased to 39.4% in 2015. In 2015, patients with an initial viral load ˃5 log copies/mL were less likely to receive NNRTI (OR=0.08) or INSTI regimens (OR=0.69) than bPIs. Patients with initial CD4+ T cell count ˂200/mm3 were less likely to receive an NNRTI (OR=0.28) or an INSTI regimen (OR=0.52) than a bPI. Women were less likely to receive an NNRTI (OR=0.79) or an INSTI regimen (OR=0.71) than a bPI; although this depended on age.CONCLUSION:The use of bPI as first-line ART declined sharply in France from 2005 to 2015. bPI remained of preferential use in patients with high viral load, low CD4+ T cell count, and in women

No relationship between late HIV diagnosis and social deprivation in newly diagnosed patients in France

International audienceOBJECTIVES:The aim of the study was to determine whether there is a relationship between social deprivation and time of HIV diagnosis in France.METHODS:Prospectively collected data from a multicentre database were used in the study. Patients with a first HIV diagnosis between 1 January 2014 and 31 December 2015 were selected from the database. Deprivation was measured using the European Deprivation Index (EDI), which is an ecological index constructed from the address of residence and based on the smallest geographical census unit, in which individuals are classified so as to be comparable with national quintiles. Time of diagnosis was classified as being at an early, intermediate, late, or advanced stage of disease. Age, gender, distance from home to HIV centre, most probable route of infection, and hepatitis B or C coinfection were considered in the analysis. Because of a strong interaction between gender and most probable route of infection, we constructed a 'population' variable: men who have sex with men (MSM), heterosexual men and women.RESULTS:Of 1421 newly diagnosed patients, 44% were diagnosed either late or at an advanced stage of disease, and 46.3% were in the highest deprivation quintile. Using multivariate logistic regression, 'population' [odds ratio (OR) 0.62 (95% confidence interval (CI) 0.48-0.78) for MSM compared with women] and age [OR 1.39 (95% CI 1.07-1.80), 1.72 (1.32-2.23) and 1.86 (1.40-2.47) for the second, third and fourth quartiles, respectively, compared with the first quartile] were found to be related to late diagnosis. EDI level was not related to late HIV diagnosis.CONCLUSIONS:'Population' seems to be more relevant than EDI to define evidence-based interventions to limit late diagnosis

Liver-related deaths in HIV-infected patients between 1995 and 2010 in France: the Mortavic 2010 study in collaboration with the Agence Nationale de Recherche sur le SIDA (ANRS) EN 20 Mortalité 2010 survey

International audienceOBJECTIVES:The aim of this study was to describe the proportion of liver-related diseases (LRDs) as a cause of death in HIV-infected patients in France and to compare the results with data from our five previous surveys.METHODS:In 2010, 24 clinical wards prospectively recorded all deaths occurring in around 26 000 HIV-infected patients who were regularly followed up. Results were compared with those of previous cross-sectional surveys conducted since 1995 using the same design.RESULTS:Among 230 reported deaths, 46 (20%) were related to AIDS and 30 (13%) to chronic liver diseases. Eighty per cent of patients who died from LRDs had chronic hepatitis C, 16.7% of them being coinfected with hepatitis B virus (HBV). Among patients who died from an LRD, excessive alcohol consumption was reported in 41%. At death, 80% of patients had undetectable HIV viral load and the median CD4 cell count was 349 cells/μL. The proportion of deaths and the mortality rate attributable to LRDs significantly increased between 1995 and 2005 from 1.5% to 16.7% and from 1.2‰ to 2.0‰, respectively, whereas they tended to decrease in 2010 to 13% and 1.1‰, respectively. Among liver-related causes of death, the proportion represented by hepatocellular carcinoma (HCC) dramatically increased from 5% in 1995 to 40% in 2010 (p = 0.019).CONCLUSIONS:The proportion of LRDs among causes of death in HIV-infected patients seems recently to have reached a plateau after a rapid increase during the decade 1995-2005. LRDs remain a leading cause of death in this population, mainly as a result of hepatitis C virus (HCV) coinfection, HCC representing almost half of liver-related causes of death

On-demand pre-exposure prophylaxis with tenofovir disoproxil fumarate plus emtricitabine among men who have sex with men with less frequent sexual intercourse: a post-hoc analysis of the ANRS IPERGAY trial

International audienceBackground: ANRS IPERGAY found that on-demand pre-exposure prophylaxis (PrEP) with oral tenofovir disoproxil fumarate plus emtricitabine was associated with an 86% relative reduction of HIV-1 incidence compared with placebo among men who have sex with men at high risk of HIV. We aimed to investigate whether on-demand PrEP was similarly effective among individuals with lower exposure to HIV risk.Methods: Participants in the ANRS IPERGAY trial were randomly assigned to receive PrEP (fixed-dose combination of 300 mg tenofovir disoproxil fumarate and 200 mg emtricitabine per pill) or placebo. The primary endpoint was the diagnosis of HIV-1 infection. Pill uptake was assessed by counting returned pills at each follow-up and by estimating tenofovir concentration from frozen plasma samples. Participants were interviewed at each visit to assess the pattern of PrEP use. All participants enrolled in the modified intention-to-treat population of the double-blind phase of the ANRS IPERGAY trial were eligible for this post-hoc analysis. We calculated the total follow-up time for periods of less frequent sexual intercourse with high PrEP adherence (15 pills or fewer per month taken systematically or often during sexual intercourse). To estimate the time of HIV acquisition, fourth-generation HIV-1/2 ELISA assays, plasma HIV-1 RNA assays, and western blot analyses were done with use of frozen samples, and the stage of HIV infection was defined according to Fiebig staging. HIV incidence was compared between the two treatment groups among individuals who had less frequent sexual intercourse with high PrEP adherence. The ANRS IPERGAY trial is registered with ClinicalTrials.gov, NCT01473472.Findings: 400 participants who were randomly assigned to receive PrEP (n=199) or placebo (n=201) between Feb 22, 2012, and Oct 17, 2014, were included in this analysis. 270 participants had at least one period of less frequent sexual intercourse with high PrEP adherence during the study, representing 134 person-years of follow-up and 31% of the total study follow-up. During these periods, participants in both groups reported a median of 5·0 (IQR 2·0-10·0) episodes of sexual intercourse per month and used a median of 9·5 (6·0-13·0) pills per month. Six HIV-1 infections were diagnosed in the placebo group (HIV incidence of 9·2 per 100 person-years; 95% CI 3·4-20·1) and none were diagnosed in the tenofovir disoproxil fumarate plus emtricitabine arm (HIV incidence of 0 per 100 person-years; 0-5·4; p=0·013), with a relative reduction of HIV incidence of 100% (95% CI 39-100).Interpretation: A choice between daily or on-demand PrEP regimens could be offered to men who have sex with men who have less frequent sexual intercourse

Kaposi sarcoma among people living with HIV in the French DAT ’ AIDS cohort between 2010 and 2015

International audienceBackground: Although antiretroviral therapy (ART) has reduced the risk of Kaposi sarcoma (KS), KS cases still occur in HIV-infected people.Objective: To describe all KS cases observed between 2010 and 2015 in a country with high ART coverage.Methods: Retrospective study using longitudinal data from 44 642 patients in the French Dat'AIDS multicenter cohort. Patients' characteristics were described at KS diagnosis according to ART exposure and to HIV-plasma viral load (HIV-pVL) (≤50 or >50) copies/mL.Results: Among the 209 KS cases diagnosed during the study period, 33.2% occurred in ART naïve patients, 17.3% in ART-experienced patients and 49.5% in patients on ART, of whom 23% for more than 6 months. Among these patients, 24 (11.5%) had HIV-pVL ≤50 cp/mL, and 16 (66%) were treated with a boosted-PI-based regimen. The distribution of KS localization did not differ by ART status nor by year of diagnosis.Limitations: Data on human herpesvirus 8, treatment modalities for KS and response rate were not collected.Conclusion: Half of KS cases observed in the study period occurred in patients not on ART, reflecting the persistence of late HIV diagnosis. Factors associated with KS in patients on ART with HIV-pVL ≤50 cp/mL remain to be explored
