High proportion of post-migration HIV acquisition in migrant men who have sex with men receiving HIV care in the Paris region, and associations with social disadvantage and sexual behaviours: results of the ANRS-MIE GANYMEDE study, France, 2021 to 2022.

BackgroundSome migrant men who have sex with men (MSM) acquire HIV in France.AimsWe investigated, in migrant MSM receiving HIV care in France, the (i) rate of post-migration-HIV acquisition in France, (ii) delay between arrival and HIV acquisition and (iii) factors affecting HIV acquisition within 1 year after migration.MethodsThis cross-sectional study focused on ≥ 18-year-old MSM born outside France, receiving HIV care in the Paris region. Information on migration history, socioeconomic condition, sexual activity, and health was collected in May 2021-June 2022 through self-administered questionnaires and medical records. Post-migration-HIV-acquisition rate and delay between arrival in France and HIV acquisition were estimated from biographical data and CD4+ T-cell counts. Predictors of HIV acquisition within 1 year after migration were determined using logistic regression.ResultsOverall post-migration HIV-acquisition rate was 61.7% (715/1,159; 95%CI: 61.2-62.2), ranging from 40.5% (95%CI: 39.6-41.6) to 85.4% (95%CI: 83.9-86.0) in participants from Latin America and North Africa. Among post-migration-HIV acquisitions, those within 1 year after migration represented 13.1% overall (95%CI: 11.6-14.6), being highest in participants from sub-Saharan Africa (25%; 95%CI: 21.5-28.3). Participants ≥ 15-years old at migration, with post-migration-acquired HIV, had a 7.5-year median interval from arrival in France to HIV acquisition (interquartile range (IQR): 3.50-14.75). Older age at arrival, region of origin (sub-Saharan Africa and Asia), degree of social disadvantage and numbers of sexual partners were independently associated with acquiring HIV within 1 year in France.ConclusionOur findings may guide HIV prevention policies for most vulnerable migrants to Europe.

HIV-1 RNA Kinetics in Blood Plasma and in Seminal Plasma of Men Starting a Dolutegravir-Based Triple-Combination Regimen at the Time of Primary HIV-1 Infection.

We compared the proportion of participants achieving first undetectable HIV-1 RNA (VL) in seminal plasma (SP) and blood plasma (BP) in 19 men starting dolutegravir-based regimen at primary HIV infection. At baseline, median VL was 6.5 (interquartile range [IQR], 5.6-7.9) and 4.5 (IQR, 3.5-5.0) log10 copies/mL in BP and SP, respectively. Between baseline and week 48, significantly higher proportion of participants achieved first VL below limit of quantification in SP (93.0%) than in BP (84.2%; P = .008). Time to first undetectable VL was 8 weeks in SP (95% confidence interval [CI], 5.6-10.4) and 24 weeks in BP (95% CI, 14.1-33.9).

Effect of Viral Replication and Liver Fibrosis on All-Cause Mortality in Human Immunodeficiency Virus-Hepatitis B Virus-Coinfected Individuals: A Retrospective Analysis of a 15-Year Longitudinal Cohort.

BACKGROUND: In individuals living with human immunodeficiency virus (HIV) and hepatitis B virus (HBV), widespread tenofovir (TDF)-containing antiretroviral therapy (ART) has led to substantial decreases in HBV-DNA and HIV-RNA detection. However, the links between viral replication, liver fibrosis, and mortality remain unclear. METHODS: A total of 300 individuals living with HIV-HBV and undergoing ART were prospectively followed. Virological and clinical data were obtained at baseline and every 6-12 months. We quantified the associations between HBV-DNA, HIV-RNA, and liver fibrosis with risk of all-cause mortality using a joint longitudinal survival model. Viral detection, viral loads, and time-averaged cumulative viral loads of HIV and HBV were modeled as 3 separate exposures. RESULTS: During a median of 10.5 years (interquartile range, 4.0-14.6), the proportion undergoing TDF-containing ART (baseline = 18.7%, end of follow-up = 79.1%) and with undetectable HBV-DNA (baseline = 36.7%, end of follow-up = 94.8%) substantially increased. 42 participants died (incidence rate = 1.30/100 person-years, 95% confidence interval [CI] = .96-1.76). The leading causes of death were non-AIDS/non-liver-related malignancies (28.6%), followed by liver-related (16.7%), AIDS-related (16.7%), and other (16.7%). All-cause mortality was associated with HBV-DNA viral load (adjusted hazards ratio [aHR] per log10 IU/mL = 1.41, 95% CI = 1.04-1.93, P = .03) or time-averaged cumulative HBV-DNA (aHR per log10 copy-years = 1.37, 95% CI = 1.03-1.83, P = .03), but not undetectable HBV-DNA. Advanced liver fibrosis at baseline was also associated with increased mortality rates (aHR = 2.35, 95% CI = 1.16-4.76, P = .02). No significant association between HIV-RNA replication and mortality was observed. CONCLUSIONS: Concurrent and historical HBV replication and liver fibrosis are important drivers of all-cause mortality in largely TDF-treated individuals living with HIV-HBV, despite one-fifth of deaths being liver-related. HBV-DNA and liver fibrosis remain important prognostic indicators for this patient population.

Atherosclerotic Cardiovascular Events in Patients Infected With Human Immunodeficiency Virus and Hepatitis C Virus.

BACKGROUND: An increased risk of cardiovascular disease (CVD) was reported in patients coinfected with human immunodeficiency virus (HIV) and hepatitis C virus (HCV), without identifying factors associated with atherosclerotic CVD (ASCVD) events. METHODS: HIV-HCV coinfected patients were enrolled in the Agence Nationale de Recherches sur le Sida et les hépatites virales (ANRS) CO13 HEPAVIH nationwide cohort. Primary outcome was total ASCVD events. Secondary outcomes were coronary and/or cerebral ASCVD events, and peripheral artery disease (PAD) ASCVD events. Incidences were estimated using the Aalen-Johansen method. Factors associated with ASCVD were identified using cause-specific Cox proportional hazards models. RESULTS: At baseline, median age of the study population (N = 1213) was 45.4 (interquartile range [IQR] 42.1-49.0) years and 70.3% were men. After a median follow-up of 5.1 (IQR 3.9-7.0) years, the incidence was 6.98 (95% confidence interval [CI], 5.19-9.38) per 1000 person-years for total ASCVD events, 4.01 (2.78-6.00) for coronary and/or cerebral events, and 3.17 (2.05-4.92) for PAD ASCVD events. Aging (hazard ratio [HR] 1.06; 95% CI, 1.01-1.12), prior CVD (HR 8.48; 95% CI, 3.14-22.91), high total cholesterol (HR 1.43; 95% CI, 1.11-1.83), high-density lipoprotein cholesterol (HR 0.22; 95% CI, 0.08-0.63), statin use (HR 3.31; 95% CI, 1.31-8.38), and high alcohol intake (HR 3.18; 95% CI, 1.35-7.52) were independently associated with total ASCVD events, whereas undetectable baseline viral load (HR 0.41, 95% CI, 0.18-0.96) was associated with coronary and/or cerebral events. CONCLUSIONS: HIV-HCV coinfected patients experienced a high incidence of ASCVD events. Some traditional cardiovascular risk factors were the main determinants of ASCVD. Controlling cholesterol abnormalities and maintaining undetectable HIV RNA are essential to control cardiovascular risk.

Persistent HBV replication and serological response during up to 15 years of tenofovir-based antiretroviral therapy in HIV/HBV-coinfected patients: a multicentre prospective cohort study.

OBJECTIVES: To determine the extent of hepatitis B virus (HBV) suppression and its association with seroclearance of hepatitis 'e' antigen (HBeAg) and hepatitis B surface antigen (HBsAg) in HIV/HBV-coinfected patients undergoing long-term tenofovir-based antiretroviral therapy (ART). METHODS: We prospectively followed 165 HIV/HBV-coinfected patients undergoing tenofovir-based ART. Serum HBV-DNA viral loads and HBeAg and HBsAg status were obtained at tenofovir initiation and every 6-12 months. We calculated the proportion achieving virological response (VR, <60 IU/mL) during follow-up. We also calculated rates of HBeAg- and HBsAg-seroclearance, which were compared between those who achieved versus never achieved VR during follow-up using an Exact binomial test. RESULTS: During a median 8.1 years (IQR = 4.0-13.2) of tenofovir treatment, 152 (92.1%) patients were able to achieve VR and 13 (7.9%) never achieved VR (median HBV-DNA at the end of follow-up = 608 IU/mL, range = 67-52 400 000). The prevalence of individuals with detectable HBV-DNA (≥60 IU/mL) decreased during tenofovir treatment: 15.1% (n = 14/93) at 5 years, 3.2% (n = 2/62) at 10 years and, 3.2% (n = 1/31) at 15 years. 44/96 HBeAg-positive patients (6.15/100 person-years) had HBeAg-seroclearance and 13/165 patients overall (0.87/100 person-years) had HBsAg-seroclearance. No difference in HBeAg-seroclearance was observed between those who achieved versus never achieved VR (7.4 versus 3.7/100 person-years, P = 0.33), while HBsAg-seroclearance was only observed in those with VR (1.0 versus 0/100 person-years, P = 0.49; respectively). Individuals with VR also had a higher frequency of undetectable HIV-RNA during treatment (P < 0.001). CONCLUSIONS: During long-term tenofovir-based ART for HIV/HBV coinfection, persistent HBV viraemia is apparent, but becomes less frequent over time. HBsAg-seroclearance only occurred in those with full HBV and relatively high HIV suppression.

Profiles of liver fibrosis evolution during long-term tenofovir treatment in HIV-positive patients coinfected with hepatitis B.

BACKGROUND & AIMS: Data on liver fibrosis evolution and its involvement in liver-related morbidity are scarce in individuals with human immunodeficiency virus (HIV) and hepatitis B virus (HBV) co-infection during treatment. We identified profiles of liver fibrosis evolution in coinfected patients undergoing tenofovir (TDF). METHODS: We included 169 HIV-HBV-coinfected patients on TDF-based antiretroviral therapy. Virological and clinical data were obtained at TDF-initiation and every 6-12 months. From data on non-invasive liver fibrosis assessments collected yearly (FibroTest®), we established clusters of individuals with similar liver fibrosis evolution using group-based trajectory models. RESULTS: Four profiles of liver fibrosis evolution were established from a median follow-up of 7.6 years (IQR = 3.1-13.1): low fibrosis with no progression (29.6%, profile A), low fibrosis with progression (22.5%, profile B), moderate fibrosis with high fluctuation (39.6%, profile C), and cirrhosis with no regression (8.3%, profile D). When compared to profile A, baseline HBeAg-positive status was associated with profiles B (P = .007) and C (P = .004), older age with profiles C (P < .001) and D (P = .001), exposure to second-generation protease inhibitors with profile C (P = .004), and CD4+ <500/mm3 at the last visit with profiles C (P = .02) and D (P = .002). Incident liver-related events occurred in profiles other than A (B, n = 1/38; C, n = 6/67; D, n = 3/14) and all five cases of hepatocellular carcinoma occurred in profiles C (n = 2) and D (n = 3). CONCLUSIONS: TDF-treated HIV-HBV coinfected individuals do not seem to benefit from comparable levels of liver fibrosis regression as in HBV mono-infection. Liver-related morbidity occurs mainly in those with fluctuating or consistently high fibrosis levels.

Kinetics of Hepatitis B Core-Related Antigen and Anti-Hepatitis B Core Antibody and Their Association With Serological Response in Human Immunodeficiency Virus-Hepatitis B Coinfection.

BACKGROUND: The aim of the current study was to describe the kinetics of quantified hepatitis B core-related antigen (qHBcrAg) and quantified anti-hepatitis B core antibody (qAnti-HBc) during tenofovir (TDF) treatment and assess their ability to predict hepatitis B e antigen (HBeAg) seroclearance in patients coinfected with human immunodeficiency virus (HIV) and hepatitis B virus. METHODS: Serum qHBcrAg, qAnti-HBc, and hepatitis B virus DNA were obtained at TDF initiation and every 6-12 months. The on-treatment kinetics of qHBcrAg (ΔqHBcrAg) and qAnti-HBc (ΔqAnti-HBc) were estimated using mixed-effect linear regression. Hazard ratios (HRs) assessing the association between markers and HBeAg seroclearance were calculated using proportional hazards regression, and the sensitivity (Se) and specificity (Sp) of marker levels in predicting HBeAg seroclearance were assessed using time-dependent receiving operating characteristic curves. RESULTS: During a median of 4.6 years, the cumulative incidences of hepatitis B surface antigen and HBeAg seroclearance were 3.2% (n = 5 of 158) and 27.4% (n = 26 of 95), respectively. ΔqHBcrAg was biphasic in HBeAg-positive patients (-0.051 and -0.011 log10 U/mL/mo during ≤18 and >18 months, respectively) and monophasic in HBeAg-negative patients. ΔqAnti-HBc was monophasic regardless of HBeAg status. In HBeAg-positive patients, baseline qHBcrAg and qAnti-HBc levels were associated with HBeAg seroclearance (adjusted HR, 0.48/log10 U/mL [95% confidence interval, .33-.70] and unadjusted HR, 1.49/log10 Paul Ehrlich Institute units/mL [1.08-2.07], respectively). Cutoffs with the highest accuracy in predicting HBeAg seroclearance at 36 months were qHBcrAg <6.5 log10 U/mL at month 24 (Se, 1; Sp, 0.58) and baseline qAnti-HBc ≥4.1 log10 Paul Ehrlich Institute units/mL (Se, 0.42; Sp, 0.81). CONCLUSIONS: In coinfected patients undergoing TDF, qHBcrAg/qAnti-HBc could be of use in monitoring HBeAg seroclearance.

Hepatitis B virus genotype G and liver fibrosis progression in chronic hepatitis B and human immunodeficiency virus coinfection.

INTRODUCTION: Infection with hepatitis B virus (HBV) genotype G has been associated with increased liver fibrosis levels compared with other genotypes in cross-sectional studies, yet its role in fibrosis evolution remains to be established. METHODS: In this prospective cohort study, 158 human immunodeficiency virus (HIV)-HBV coinfected patients had available HBV genotyping at baseline. Liver fibrosis was assessed at baseline and every 6 to 12 months by the FibroTest (BioPredictive, Paris, France). Risk factors for fibrosis regression (F3-F4 to F0-F1-F2) and progression (F0-F1-F2 to F3-F4) between baseline and end of follow-up were evaluated. RESULTS: Most patients were male (88.6%) with a median age of 39 years. HBV genotype A was more prevalent compared with other HBV genotypes (62.7% vs D = 10.8%, E = 10.8%, and G = 15.8%). Patients were followed up for a median of 83 months (IQR = 37-97). In the 43 (27.2%) patients with F3-F4 baseline liver fibrosis, 7 (16.2%) regressed to F0-F1-F2 fibrosis at the last follow-up visit. In the 115 (72.8%) with F0-F1-F2 fibrosis at baseline, 19 (16.5%) progressed to F3-F4 fibrosis at last visit. In multivariable analysis, fibrosis progression was independently associated with older age (P <0.005), baseline CD4+ cell count less than 350/mm 3 ( P <0.01), longer antiretroviral therapy duration ( P <0.03), and HBV genotype G infection (vs non-G, P <0.01). When examining averages over time, the rate of FibroTest increase was faster in genotype G vs non-G-infected patients with baseline F0-F1-F2 fibrosis ( P for interaction = 0.002). CONCLUSION: In HIV-HBV coinfected patients, HBV genotype G is an independent risk factor for liver fibrosis progression as determined by noninvasive markers. HBV genotype G-infected patients with low initial liver fibrosis levels may require more careful monitoring.

Efficacy and safety of direct-acting antiviral regimens in HIV/HCV-co-infected patients - French ANRS CO13 HEPAVIH cohort.

BACKGROUND & AIMS: There is little data available on the use of new oral direct-acting antiviral (DAA) regimens to treat human immunodeficiency virus and hepatitis C virus (HIV/HCV) co-infected patients in real-life settings. Here, the efficacy and safety of all-oral DAA-based regimens in HIV/HCV-co-infected patients enrolled in the French nationwide ANRS CO13 HEPAVIH observational cohort are reported. METHODS: HIV/HCV-co-infected patients enrolled in the ANRS CO13 HEPAVIH observational cohort were included if they began an all-oral DAA-based regimen before 1st May 2015 (12-week regimens) or 1st February 2015 (24-week regimens). Treatment success (SVR12) was defined by undetectable HCV-RNA 12weeks after treatment cessation. Exact logistic regression analysis was used to identify factors associated with SVR12. RESULTS: A total of 323 patients (74% men) with a median age of 53years were included, 99% of whom were on combination antiretroviral therapy (cART). HIV RNA load was <50 copies/ml in 88% of patients; median CD4 cell count was 540/mm3; 60% of patients were cirrhotic; 68% had previously received unsuccessful anti-HCV treatment. cART was protease inhibitor (PI)-based in 23%, non-nucleoside reverse transcriptase inhibitor (NNRTI)-based in 15%, and integrase inhibitor (II)-based in 38%, while 24% of patients received other regimens. The SVR12 rate was 93.5% overall (95% confidence interval [CI]: 90.2-95.9), 93.3% (88.8-96.4) in patients with cirrhosis and 93.8% (88.1-97.3) in patients without cirrhosis. The SVR12 rates were 93.1% (84.5-97.7), 91.8% (80.4-97.7) and 95.8% (90.5-98.6) respectively, in patients receiving PI-based, NNRTI-based and II-based cART. In adjusted analysis, SVR12 was not associated with HIV RNA load, the cART regimen, cirrhosis, prior anti-HCV treatment, the duration of anti-HCV therapy, or ribavirin use. The most common adverse effects were fatigue and digestive disorders. CONCLUSIONS: New all-oral DAA regimens were well-tolerated and yielded high SVR12 rates in HIV/HCV-co-infected patients. LAY SUMMARY: We evaluated efficacy and safety of all-oral DAA regimens in a large French nationwide observational cohort study of HIV/HCV co-infected patients. Sustained virological response 12weeks after treatment cessation was 93.5% overall. The all-oral DAA regimens were well-tolerated and most common adverse effects were fatigue and digestive disorders.

Infectious Zika virus in vaginal secretions from an HIV-infected woman, France, August 2016.

A woman with controlled HIV infection developed in late August 2016 a pruritic rash with fever and conjunctival hyperaemia after a trip to the French Caribbean islands. On day 3 after symptom onset, Zika virus RNA was detected in plasma, urine and vaginal samples with respective viral loads of 3.8, 6.1 and 5.3 log copies/mL. Notably, we demonstrated the presence of infectious Zika virus particles in the vaginal samples by isolation in cell culture.

All-oral Direct-acting Antiviral Regimens in HIV/Hepatitis C Virus-coinfected Patients With Cirrhosis Are Efficient and Safe: Real-life Results From the Prospective ANRS CO13-HEPAVIH Cohort.

BACKGROUND: Human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients with cirrhosis have long been considered to be difficult to treat, and real-life efficacy and tolerance data with all-oral direct-acting antiviral (DAA) combinations in these patients are scarce. METHODS: Cirrhotic HIV/HCV-coinfected patients enrolled in the French National Agency for Research on AIDS and Viral Hepatitis (ANRS) CO13 HEPAVIH cohort initiating an all-oral DAA regimen were consecutively included. A negative HCV RNA result at 12 weeks of follow-up or thereafter was assumed as a sustained virologic response (SVR12). Adjusted exact logistic regression was used to study factors associated with treatment outcome. RESULTS: We included 189 patients who initiated an all-oral DAA regimen with the following characteristics: median age 53.2 years; 74.6% male; Centers for Disease Control and Prevention classification A/B/C: 37%/31%/32%; Child-Pugh class A/B/C: 91%/8%/1%; 87% with HIV RNA <50 copies/mL; 99% on antiretrovirals; median CD4 count: 489 cells/µL; HCV treatment naive 29%; HCV genotype 1/2/3/4: 58%/4%/17%/21%. Sofosbuvir (SOF) + daclatasvir ± ribavirin (RBV) was used in 123 patients, SOF + RBV in 30, SOF + simeprevir in 11, and SOF + ledipasvir in 23. An SVR12 was reported in 93.1% of the patients (95% confidence interval, 88.5%-96.3%). In adjusted analyses, no difference was found between 12 or 24 weeks of treatment, in patients receiving RBV or not, and in treatment-naive vs experienced patients. Premature stop of DAA was reported for 8 patients. One patient died during treatment (unknown cause), and 12 other patients developed liver-related events. CONCLUSIONS: In this prospective real-life cohort, all-oral DAA regimens were well tolerated and associated with a high virologic efficacy in cirrhotic HIV/HCV-coinfected patients. This should not alleviate the surveillance for liver-related events in these patients.

Decay of ccc-DNA marks persistence of intrahepatic viral DNA synthesis under tenofovir in HIV-HBV co-infected patients.

BACKGROUND & AIMS: In the presence of highly-potent antivirals, persistence of hepatitis B virus (HBV) is most well-characterized by covalently-closed circular DNA (cccDNA) and total intrahepatic DNA (IH-DNA). We sought to determine how antiviral therapy could affect their levels during human immunodeficiency virus (HIV)-HBV co-infection. METHODS: Sixty co-infected patients from a well-defined cohort with ⩾1 liver biopsy were studied. HBV cccDNA and total IH-DNA were extracted from biopsies and quantified by real-time PCR. Factors associated with intrahepatic viral load were determined using mixed-effect linear regression and half-life viral kinetics during reconstructed follow-up using non-linear exponential decay models. RESULTS: At biopsy, 35 (58.3%) patients were hepatitis B "e" antigen (HBeAg)-positive and 33 (55.0%) had detectable plasma HBV-DNA (median=4.58log10IU/ml, IQR=2.95-7.43). Overall, median cccDNA was -0.95log10copies/cell (IQR=-1.70, -0.17) and total IH-DNA was 0.27log10copies/cell (IQR=-0.39, 2.00). In multivariable analysis, significantly lower levels of cccDNA and total IH-DNA were observed in patients with HBeAg-negative serology, nadir CD4(+) cell counts >250/mm(3), and longer cumulative TDF-duration, but not lamivudine- or adefovir-duration. In post-hoc analysis using reconstructed TDF-duration (median 29.6months, IQR=15.0-36.1, n=31), average half-life of cccDNA was estimated at 9.2months (HBeAg-positive=8.6, HBeAg-negative=26.2) and total IH DNA at 5.8months (HBeAg-positive=1.3, HBeAg-negative=13.6). Intrahepatic viral loads remained detectable for all patients, even with prolonged TDF-exposure. CONCLUSIONS: In co-infection, TDF-use is associated with lower levels of HBV replication intermediates and cccDNA. Slow decay of intrahepatic viral loads underscores that TDF is unable to completely block intracellular viral DNA synthesis, which possibly accounts for continuous replenishment of the cccDNA pool. LAY SUMMARY: Chronic hepatitis B virus (HBV) is a persistent infection, while the only real way of knowing the extent of this persistence is through measuring levels of virus in the liver. In this study, we examine levels of HBV in the liver among patients with both HBV and human immunodeficiency virus, or HIV, infection. It would appear that the currently available medication, namely "tenofovir", works well to decrease virus levels in the liver, but it remains at low levels despite long periods of treatment.

Drug resistance and tropism as markers of the dynamics of HIV-1 DNA quasispecies in blood cells of heavily pretreated patients who achieved sustained virological suppression.

OBJECTIVES: The objective of this study was to address the dynamics of archived resistant quasispecies in cell-associated HIV-1 DNA over time in heavily ART-experienced patients with currently suppressed plasma HIV-1 RNA. METHODS: Longitudinal ultra-deep sequencing (UDS) analysis of reverse transcriptase, protease and V3 Env regions was performed on blood-cell-associated HIV-1 DNA samples. Drug-resistance-associated mutations (DRAMs) and tropism were interpreted using the ANRS and Geno2Pheno algorithms. We analysed frozen blood cells from patients enrolled in the INNOVE and ANRS 123 ETOILE studies who achieved sustained viral suppression after salvage optimized ART (SOT). RESULTS: Samples were available at baseline and 6 and ≥12 months after SOT initiation in 10 patients. V3 loop sequences displayed wide intra-individual dynamics over time. Viral variants harbouring DRAMs exhibited three non-exclusive scenarios. First, when SOT exerted the same selective pressure as previous failing regimens, some viral quasispecies still harboured the same DRAMs at the same level as at the time of virological failure. Thus, as DRAMs were mostly associated with the same viral variant, variants with a complete resistance pattern remained archived. Second, some viral variants harbouring DRAMs were no longer detected over time when SOT consisted of new antiretroviral classes or had resistance profiles distinct from those of previous failing regimens. Third, variants with new DRAMs associated with SOT emerged in blood cells during follow-up despite sustained virological control. CONCLUSIONS: Using longitudinal UDS analysis and focusing on DRAMs and tropism as markers, we demonstrated that, despite sustained virological control, archived HIV-1 DNA quasispecies continued to evolve.

Plasma cholesterol efflux capacity from human THP-1 macrophages is reduced in HIV-infected patients: impact of HAART.

The capacity of HDL to remove cholesterol from macrophages is inversely associated with the severity of angiographic coronary artery disease. The effect of human immunodeficiency virus (HIV) infection or its treatment on the ability of HDL particles to stimulate cholesterol efflux from human macrophages has never been studied. We evaluated the capacity of whole plasma and isolated HDL particles from HIV-infected subjects (n = 231) and uninfected controls (n = 200), as well as in a subset of 41 HIV subjects receiving highly active antiretroviral therapy (HAART) to mediate cholesterol efflux from human macrophages. Plasma cholesterol efflux capacity was reduced (-12%; P = 0.001) in HIV patients as compared with controls. HIV infection reduced by 27% (P < 0.05) the capacity of HDL subfractions to promote cholesterol efflux from macrophages. We observed a reduced ABCA1-dependent efflux capacity of plasma (-27%; P < 0.0001) from HIV-infected subjects as a result of a reduction in the efflux capacity of HDL3 particles. HAART administration restored the capacity of plasma from HIV patients to stimulate cholesterol efflux from human macrophages (9.4%; P = 0.04). During HIV infection, the capacity of whole plasma to remove cholesterol from macrophages is reduced, thus potentially contributing to the increased coronary heart disease in the HIV population. HAART administration restored the removal of cholesterol from macrophages by increasing HDL functionality.

Cannabis Use and Reduced Risk of Insulin Resistance in HIV-HCV Infected Patients: A Longitudinal Analysis (ANRS CO13 HEPAVIH).

BACKGROUND: Diabetes and insulin resistance (IR) is common in human immunodeficiency virus-hepatitis C virus (HIV-HCV)-coinfected patients, a population also concerned with elevated cannabis use. Cannabis has been associated with reduced IR risk in some population-based surveys. We determined whether cannabis use was consistently associated with reduced IR risk in HEPAVIH, a French nationwide cohort of HIV-HCV-coinfected patients. METHODS: HEPAVIH medical and sociobehavioral data were collected (using annual self-administered questionnaires). We used 60 months of follow-up data for patients with at least 1 medical visit where IR (using homeostatic model assessment of insulin resistance [HOMA-IR]) and cannabis use were assessed. A mixed logistic regression model was used to evaluate the association between IR risk (HOMA-IR > 2.77) and cannabis use (occasional, regular, daily). RESULTS: Among the 703 patients included in the study (1287 visits), 323 (46%) had HOMA-IR > 2.77 for at least 1 follow-up visit and 319 (45%) reported cannabis use in the 6 months before the first available visit. Cannabis users (irrespective of frequency) were less likely to have HOMA-IR > 2.77 (odds ratio [95% confidence interval], 0.4 [.2-.5]) after adjustment for known correlates/confounders. Two sensitivity analyses with HOMA-IR values as a continuous variable and a cutoff value of 3.8 confirmed the association between reduced IR risk and cannabis use. CONCLUSIONS: Cannabis use is associated with a lower IR risk in HIV-HCV-coinfected patients. The benefits of cannabis-based pharmacotherapies for patients concerned with increased risk of IR and diabetes need to be evaluated in clinical research and practice.

Combined ART started during acute HIV infection protects central memory CD4+ T cells and can induce remission.

BACKGROUND: Therapeutic control of HIV replication reduces the size of the viral reservoir, particularly among central memory CD4+ T cells, and this effect might be accentuated by early treatment. METHODS: We examined the effect of ART initiated at the time of the primary HIV infection (early ART), lasting 2 and 6 years in 11 and 10 patients, respectively, on the HIV reservoir in peripheral resting CD4+ T cells, sorted into naive (TN), central memory (TCM), transitional memory (TTM) and effector memory (TEM) cells, by comparison with 11 post-treatment controllers (PTCs). RESULTS: Between baseline and 2 years, CD4+ T cell subset numbers increased markedly (P < 0.004) and HIV DNA levels decreased in all subsets (P < 0.009). TTM cells represented the majority of reservoir cells at both timepoints, T cell activation status normalized and viral diversity remained stable over time. The HIV reservoir was smaller after 6 years of early ART than after 2 years (P < 0.019), and did not differ between PTCs and patients treated for 6 years. One patient, who had low reservoir levels in all T cell subsets after 2 years of treatment similar to the levels in PTCs, spontaneously controlled viral replication during 18 months off treatment. CONCLUSIONS: Early prolonged ART thus limits the size of the HIV reservoir, protects long-lived cells from persistent infection and may enhance post-treatment control.

Telaprevir for HIV/hepatitis C virus-coinfected patients failing treatment with pegylated interferon/ribavirin (ANRS HC26 TelapreVIH): an open-label, single-arm, phase 2 trial.

BACKGROUND: 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. METHODS: 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). RESULTS: 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. CONCLUSIONS: Despite a high discontinuation rate related to toxicity, a substantial proportion of treatment-experienced HIV-coinfected patients achieved SVR24 with a telaprevir-based regimen.

Role of a 48-week pegylated interferon therapy in hepatitis B e antigen positive HIV-co-infected patients on cART including tenofovir: EMVIPEG study.

BACKGROUND & AIMS: In hepatitis B e antigen (HBeAg) positive-HIV co-infected patients treated with combined antiretroviral therapy (cART), including tenofovir disoproxil fumarate (TDF), the rate of HBe seroconversion remains low. Whether adding pegylated interferon alfa (PegIFN) could increase the likelihood of HBeAg loss and HBe seroconversion has not been assessed. METHODS: A 48-week PegIFN therapy was added to HBeAg positive-HIV co-infected patients on TDF and emtricitabine, or lamivudine for at least 6 months. The primary endpoint was HBV sustained response: HBe seroconversion with undetectable HBV DNA levels 24 weeks after completing PegIFN therapy (W72). RESULTS: Fifty-one patients (49 men, median age 46 years, range: 32-65), were included. Median duration of HIV, HBV infections and TDF therapy was 10.3 (0.6-22), 9.8 (0.5-16), and 3.3 (0.5-6.8)years, respectively. Median baseline CD4 count was 506 (175-1316)/mm(3). HIV viral load was <50 copies/ml in 49 (96%) patients. Nine (18%) patients stopped PegIFN prematurely. Ten (20%) patients experienced HBeAg loss at W72 and four (8%) patients had a HBV sustained response. No HBs seroconversion was observed. Only patients with more than 350 CD4/mm(3) at baseline achieved HBe loss. HBeAg level >10 PEIU/ml at W12 or a quantitative HBsAg decline <0.5 log IU/ml at W24 had 100% and 84% negative predictive values for response, respectively. CONCLUSIONS: 48-week PegIFN additional therapy to cART including TDF did not significantly increase the HBe seroconversion rate, despite an HBeAg loss in 20% of the patients. HBe and HBs kinetics may nevertheless be of help in tailoring and optimising this strategy.
