Screening HIV Patients at Risk for NAFLD Using MRI-PDFF and Transient Elastography: A European Multicenter Prospective Study.

BACKGROUND & AIMS: Nonalcoholic fatty liver disease (NAFLD) is a growing concern in the aging population with human immunodeficiency virus (HIV). Screening for NAFLD is recommended in patients with metabolic risk factors or unexplained transaminitis. This study aimed to prospectively assess the prevalence and associated factors of liver steatosis and advanced fibrosis (AF) in HIV-monoinfected patients at risk of NAFLD. METHODS: We conducted a multicenter study in HIV-monoinfected patients, nonexcessive drinkers with metabolic syndrome, and/or persistently elevated liver enzymes, and/or clinical lipodystrophy. All participants had magnetic resonance imaging proton density fat fraction (MRI-PDFF), Fibroscan/controlled attenuation parameter (CAP), and cytokine and genetic analysis. RESULTS: From March 2014 to November 2015, we enrolled 442 participants and analyzed 402: male (85%); median age, 55 years (interquartile range [IQR], 50-61 years); body mass index, 27.0 kg/m2 (IQR, 23.6-28.7 kg/m2); metabolic syndrome (67%); and CD4 cell count, 630/mm3 (IQR, 510-832/mm3). Overall 257 of 402 (64%) had NAFLD (MRI-PDFF ≥5%). Among them, 11.3% had a liver stiffness ≥9.6 kPa, suggestive of AF. Multivariable analysis identified 7 factors of steatosis: high CD4-cell count (odds ratio [OR], 4.04; 95% confidence interval [CI], 1.92-8.51), high leptin level (OR, 2.12; 95% CI, 1.14-3.93), non-CC PNPLA3s738409 genetic polymorphism (OR, 1.92; 95% CI, 1.11-3.33), low high-density lipoprotein (OR, 1.83; 95% CI, 1.03-3.27), high triglycerides (OR, 1.48; 95% CI, 1.18-1.84), elevated alanine transaminase (OR, 1.23; 95% CI, 1.16-1.31), and hyper ferritinemia (OR, 1.05; 95% CI, 1.03-1.07). Two factors were associated with AF: high body mass index (OR, 1.23 ; 95% CI, 1.07-1.42 ; P = .005, and elevated aspartate aminotransferase (OR, 1.03; 95% CI, 1.01-1.05; P = .001). Using MRI-PDFF as a reference, CAP (best cutoff, 280 dB/m) had good accuracy (area under the receiver operating characteristic curve = 0.86; 95% CI, 0.82-0.90) for the diagnosis of moderate to severe steatosis. CONCLUSIONS: In a large cohort of HIV-moninfected patients at risk of NAFLD, steatosis is present in two-thirds of cases, and around 10% have AF. The CAP technique is accurate for screening steatosis in this population.

Prophylaxis by doravirine-lamivudine-tenofovir disoproxil fumarate or elvitegravir-cobicistat-emtricitabine-tenofovir alafenamide after sexual exposure to HIV.

HIV post- exposure prophylaxis (PEP) is a prevention tool for individuals with a recent potential exposure to HIV. Doravirine has been available since 2019 in combination with tenofovir disoproxil fumarate and lamivudine and has not been evaluated as a PEP. DOR/3TC/TDF is our department's most commonly prescribed PEP treatment since 2021. This study evaluates the completion rate of the DOR/3TC/TDF as compared to EVG/c/FTC/TAF for PEP, which was the regimen prescribed until 2020 in our hospital.This retrospective observational study was conducted between January 2020 and September 2021. The subjects included consecutively were adults who consulted for an HIV sexual exposure accident and for whom DOR/3TC/TDF in 2021 or EVG/c/FTC/TAF in 2020 was prescribed. The outcomes were the completion rate to the end of treatment (28 days), the seroconversion rate, and the description of side effects.During the study period, 311 people were included: 140 treated with DOR/3TC/TDF and 171 treated with EVGc/FTC/TAF. Considering subjects with a follow-up visit, the completion rate was 96.8% (90/93) in the DOR/3TC/TDF group, and 94.6% (123/130) in the EVG/c/FTC/TAF group (p-value: 0.53). The number of people lost to follow-up was nearly equivalent in both groups: 27.1% (38/140) in the DOR/3TC/TDF group and 23.4% (40/171) in the EVG/c/FTC/TAF group (p-value: 0.45). A side effect was described for 38% (36/94) in the DOR/3TC/TDF group, and 29.7% (38/128) in the EVG/c/FTC/TAF group. No cases of seroconversion were observed.DOR/3TC/TDF appears to have a similar safety profile to EVG/c/FTC/TAF. Due to its lower cost, it seems to be a treatment option for consideration in the context of HIV-exposure accidents.

Evidence of Sexual Transmission of Extended-Spectrum ß-Lactamase-Producing Enterobacterales: A Cross-sectional and Prospective Study.

BACKGROUND: Extended-spectrum ß-lactamase-producing Enterobacterales (ESBL-E) represent a major threat to public health. Little is known on their potential for sexual transmission. METHODS: We recruited individuals at a sexually transmitted infection and human immunodeficiency virus (HIV) outpatient clinic in Paris, France, in whom we evaluated the prevalence of ESBL-E intestinal carriage and, among those testing positive, the proportion with clearance 6 months thereafter. We compared carriage prevalence between groups using logistic regression adjusted for age, geographic origin, travel outside Europe, and antibiotic use in the past 6 months. RESULTS: A total of 2157 individuals participated, of whom 226 (10.5%) were ESBL-E carriers. The proportions of ESBL-E carriers varied across sexual groups and were as follows: HIV-negative men who have sex with men (MSM) and who were on preexposure prophylaxis (PrEP), 16.3% (41 of 251); HIV-negative MSM not on PrEP, 9.7% (47 of 487); HIV-positive MSM, 12.2% (61 of 500); HIV-negative men who have sex exclusively with women, 10.0% (44 of 439); and HIV-negative women who have sex with men, 6.9% (n = 33 of 480). After adjustment, ESBL-E prevalence was significantly higher in HIV-negative MSM on PrEP (P < .001) and HIV-positive MSM (P = .01) than in women who have sex with men. A higher number of sexual partners in the past 6 months was associated with ESBL-E carriage after adjustment (P = .004). Escherichia coli sequence type 14 and blaSHV-12-producing ESBL-E were observed only in MSM. Of 102 individuals with ESBL-E returning for testing, 26 (25%) had carriage at 6 months. CONCLUSION: ESBL-E carriage is more frequent in MSM undergoing PrEP or living with HIV and with increasing number of sexual partners. More research is warranted to understand the consequences of ESBL-E carriage in these populations and how transmission can be reduced.

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.

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.

Grazoprevir/elbasvir for the immediate treatment of recently acquired HCV genotype 1 or 4 infection in MSM.

BACKGROUND: In Europe, increases in HCV infection have been observed over the last two decades in MSM, making them a key population for recently acquired HCV. Alternative combinations of direct-acting antiviral agents against early HCV infection need to be assessed. PATIENTS AND METHODS: In this pilot trial, MSM with recently acquired genotype 1 or 4 HCV infection were prospectively included and received 8 weeks of oral grazoprevir 100 mg and elbasvir 50 mg in a fixed-dose combination administered once daily. The primary endpoint was sustained virological response evaluated 12 weeks after the end of treatment (EOT) (SVR12). Secondary endpoints were the virological characterization of failures, the quality of life before, during and after treatment and the rate of reinfection. RESULTS: In a 15 month period, 30 patients were enrolled, all of whom were MSM. Of the 29 patients completing follow-up, 28 (96%, 95% CI = 82%-99%) achieved SVR12. One patient interrupted follow-up (suicide) but had undetectable plasma HCV RNA at EOT. One patient with suboptimal adherence confirmed by plasma drug monitoring relapsed and developed NS3, NS5A and NS5B resistance-associated substitutions (V36M, M28V and S556G). The most common adverse events related to study drug were diarrhoea (n = 4, 13%), insomnia (n = 2, 7%) and fatigue (n = 2, 7%), although no patient discontinued treatment. No HIV RNA breakthrough was reported in the 28 patients with HIV coinfection. At Week 48, reinfection was diagnosed in three patients. CONCLUSIONS: Our data support the use of grazoprevir/elbasvir for immediate treatment against HCV in order to reduce HCV transmission in MSM.

Evaluating interventions to reduce behaviour associated with HCV reinfection in men who have sex with men: study protocol for a non-blinded, phase 2, randomised trial.

BACKGROUND: As highly effective therapy against hepatitis C virus (HCV) infection is available with rapid uptake, there is newfound optimism for HCV elimination. Nevertheless, certain key populations have a high risk of HCV reinfection, in particular men who have sex with men (MSM) in Western European countries. Modelling data indicate that HCV elimination will not be feasible without reduction in risk behaviour, thus supporting the need for effective interventions aimed at reducing risk behaviour and preventing reinfections in MSM. METHODS: The ICECREAM study is an international, multi-centred, phase 2, 3-arm randomised trial comparing run-in and intervention periods enrolling MSM with a history of a cured or spontaneously cleared HCV infection. Individuals are followed in routine care for 6 months (i.e. run-in period) and then randomly allocated (1:1:1) to one of the following: a tailored, interactive online risk-reduction behavioural intervention, a validated home-based HCV-RNA self-sampling test service using dried blood spots, or a combination of both. After randomisation, individuals are followed every 6 months until 18 months (i.e. intervention period). Interventions are delivered in addition to standard of care. Online questionnaire measuring risk behaviour over the past 6 months is administered at every visit. The primary outcome is the proportion at risk of HCV infection during run-in versus intervention periods assessed by using the HCV-MOSAIC risk score. The risk score consists of six self-reported HCV-related risk behaviours. Secondary outcomes include incidence of HCV reinfection, changes in the individual risk behaviour items and changes in sexual well-being since changes in sexual behaviour may have an impact on sexual experience. Two hundred forty-six MSM aged 18 years or older will be invited to participate. DISCUSSION: The ICECREAM study is a trial aimed at establishing interventions that could effectively decrease the incidence of HCV re-infection in MSM with a previous HCV infection. By offering an online behavioural risk-reduction intervention and HCV-RNA self-sampling, both of which are aimed to influence risk behaviour, we are able to provide products to at-risk MSM that could further reduce population-level HCV incidence and ultimately help reach HCV micro-elimination. TRIAL REGISTRATION: ClinicalTrials.gov NCT04156945. Registered on November 8, 2019.

Understanding the Risks and Benefits of a Patient Portal Configured for HIV Care: Patient and Healthcare Professional Perspectives.

BACKGROUND: Like other chronic viral illnesses, HIV infection necessitates consistent self-management and adherence to care and treatment, which in turn relies on optimal collaboration between patients and healthcare professionals (HCPs), including physicians, nurses, pharmacists, and clinical care coordinators. By providing people living with HIV (PLHIV) with access to their personal health information, educational material, and a communication channel with HCPs, a tailored patient portal could support their engagement in care. Our team intends to implement a patient portal in HIV-specialized clinics in Canada and France. We sought to understand the perceived risks and benefits among PLHIV and HCPs of patient portal use in HIV clinical care. METHODS: This qualitative study recruited PLHIV and HIV-specialized HCPs, through maximum variation sampling and purposeful sampling, respectively. Semi-structured focus group discussions (FGDs) were held separately with PLHIV and HCPs between August 2019 and January 2020. FGDs were recorded, transcribed, coded using NVivo 12 software, and analyzed using content analysis. RESULTS: A total of twenty-eight PLHIV participated in four FGDs, and thirty-one HCPs participated in six FGDs. PLHIV included eighteen men, nine women, and one person identifying as other; while, HCPs included ten men, twenty women, and one person identifying as other. A multi-disciplinary team of HCPs were included, involving physicians, nurses, pharmacists, social workers, and clinical coordinators. Participants identified five potential risks: (1) breach of confidentiality, (2) stress or uncertainty, (3) contribution to the digital divide, (4) dehumanization of care, and (5) increase in HCPs' workload. They also highlighted four main benefits of using a patient portal: (1) improvement in HIV self-management, (2) facilitation of patient visits, (3) responsiveness to patient preferences, and (4) fulfillment of current or evolving patient needs. CONCLUSION: PLHIV and HCPs identified both risks and benefits of using a patient portal in HIV care. By engaging stakeholders and understanding their perspectives, the configuration of a patient portal can be optimized for end-users and concerns may be mitigated during its implementation.

Subclinical and Clinical Outcomes in Patients Coinfected With HIV and Chronic Hepatitis B Virus From Clinical Outpatient Centers in France: Protocol for an Ambispective, Longitudinal Cohort Study.

BACKGROUND: Previous large-scale studies have examined the effect of chronic hepatitis B virus (HBV) infection on overall and cause-specific mortality in individuals with HIV. However, few studies have collected data on the subclinical indicators of HBV that lead to these severe outcomes in the coinfected population. OBJECTIVE: In this study, we aim to describe the procedures of a cohort study extension aimed at assessing HBV-DNA replication, serological markers of HBV (hepatitis B e antigen [HBeAg] and hepatitis B surface antigen), and liver fibrosis and how these subclinical outcomes relate to mortality in predominately tenofovir-treated, coinfected patients with HIV-HBV. We assessed the characteristics at cohort inclusion of those who participated in the cohort extension, as well as those who did not participate due to being lost to follow-up or death. METHODS: Patients with HIV and chronic HBV who completed follow-up in a prospective cohort study conducted in 4 outpatient centers (Paris and Lyon, France; 2002-2011) were invited to participate in a cross-sectional visit from November 2016 to March 2018, during which a comprehensive evaluation of HIV- and HBV-related disease was undertaken. Virological and clinical data since the previous study visit were retrospectively collected. RESULTS: Of the 308 individuals enrolled in the cohort, 147 (47.7%) participated in the cross-sectional study. At this visit, most participants were HBeAg negative (111/134, 82.8% with available data), had undetectable HBV DNA (124/132, 93.9% with available data), and were undergoing antiretroviral therapy containing tenofovir disoproxil fumarate or tenofovir alafenamide (114/147, 77.6%). There were no significant differences in characteristics at cohort inclusion between those who did and did not complete the cross-sectional visit, except for a lower proportion with an AIDS-defining illness (30/147, 20.5% vs 49/161, 30.4%, respectively; P=.04). Of the 161 nonparticipating individuals, 42 (26.1%) died, 41 (25.4%) were lost to follow-up and known to be alive, and 78 (48.4%) were lost to follow-up with unknown vital status. Most differences in characteristics at cohort inclusion were observed between deceased individuals and those participating in the cross-sectional visit or those lost to follow-up. With this extension, the median follow-up time of the overall cohort is presently 9.2 years (IQR 3.4-14.6). CONCLUSIONS: Extended follow-up of the French HIV-HBV cohort will provide important long-term data on the subclinical trajectory of HBV disease in the coinfected population. The biases due to the relatively high rate of those lost to follow-up need to be assessed in future studies of this cohort. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/24731.

Acceptability of a Patient Portal (Opal) in HIV Clinical Care: A Feasibility Study.

Opal (opalmedapps.com), a patient portal in use at the Cedars Cancer Centre of the McGill University Health Centre (MUHC) (Montreal, Canada), gives cancer patients access to their medical records, collects information on patient-reported outcome measures (PROMs), and has demonstrated patient satisfaction with care. This feasibility study aims to evaluate Opal's potential acceptability in the context of HIV care. People living with HIV (PLWH) and their healthcare providers (HCPs) completed cross-sectional surveys from August 2019 to February 2020 at large HIV centers, including the Chronic Viral Illness Service of the MUHC, and other HIV clinical sites in Montreal and Paris, France. This study comprised 114 PLWH (mean age 48 years old, SD = 12.4), including 74% men, 24% women, and 2% transgender or other; and 31 HCPs (mean age 46.5 years old, SD = 11.4), including 32% men, 65% women, and 3% other. Ownership of smartphones and tablets was high (93% PLWH, 96% HCPs), and participants were willing to use Opal (74% PLWH, 68% HCPs). Participants were interested in most Opal functions and PROMs, particularly PROMs capturing quality of life (89% PLWH, 77% HCPs), experience of healthcare (86% PLWH, 97% HCPs), and HIV self-management (92% PLWH, 97% HCPs). This study suggests Opal has high acceptability and potential usefulness as perceived by PLWH and HCPs.

Correlation of serum hepatitis B core-related antigen with hepatitis B virus total intrahepatic DNA and covalently closed circular-DNA viral load in HIV-hepatitis B coinfection.

OBJECTIVE: To assess whether quantified hepatitis B core-related antigen (qHBcrAg) is a surrogate marker of intrahepatic replication in HIV and hepatitis B virus (HBV) coinfection. DESIGN: Cross-sectional study of 31 HIV-HBV-infected patients (total liver biopsies, n = 38) from a well defined cohort. METHODS: Spearman's rank correlation coefficients were calculated between qHBcrAg and intrahepatic markers of HBV replication [total intrahepatic-DNA, covalently closed circular (ccc) DNA, cccDNA : total intrahepatic-DNA ratio]. RESULTS: At biopsy, 22 (71.0%) patients were hepatitis B 'e' antigen (HBeAg)-positive, 22 (71.0%) had detectable plasma HBV-DNA, and 17 (54.8%) were treated with tenofovir. Median levels (interquartile range) of intrahepatic markers were as follows: HBV cccDNA (n = 34), 0.26 copies/cell (0.4-2.89); total intrahepatic-DNA (n = 38), 2.38 copies/cell (0.58-207.9), and cccDNA : total intrahepatic-DNA ratio (n = 34), 0.05 (interquartile range = 0.01-0.12). There was a significantly strong correlation between qHBcrAg and cccDNA in all patients (Rho = 0.65, P < 0.001), while a moderate correlation was observed between qHBcrAg and total intrahepatic-DNA (Rho = 0.57, P < 0.001) or cccDNA : total intrahepatic-DNA ratio (Rho = -0.45, P = 0.01). Similar findings were observed for HBeAg-positive patients and those with detectable HBV-DNA, with the exception of qHBcrAg and cccDNA or cccDNA : total intrahepatic-DNA ratio. In contrast, no significant correlation between qHBcrAg and any intrahepatic marker was observed in HBeAg-negative patients or those with undetectable HBV-DNA. No significant difference was observed in median qHBcrAg levels across liver fibrosis stages (P = 0.5). CONCLUSION: qHBcrAg is a potential surrogate marker of cccDNA in HIV-HBV coinfected patients, yet might be less useful with undetectable serum HBV-DNA or HBeAg-negative status. Whether qHBcrAg provides further clinical utility compared with other serological markers remains debatable.

Association of Hepatitis B Core-Related Antigen and Antihepatitis B Core Antibody With Liver Fibrosis Evolution in Human Immunodeficiency Virus-Hepatitis B Virus Coinfected Patients During Treatment With Tenofovir.

BACKGROUND: Quantitative hepatitis B core-related antigen (qHBcrAg) or antihepatitis B core antibody (qAnti-HBc) could be useful in monitoring liver fibrosis evolution during chronic hepatitis B virus (HBV) infection, yet it has not been assessed in human immunodeficiency virus (HIV)-HBV-coinfected patients undergoing treatment with tenofovir (TDF). METHODS: One hundred fifty-four HIV-HBV-infected patients initiating a TDF-containing antiretroviral regimen were prospectively followed. The qHBcrAg and qAnti-HBc and liver fibrosis assessment were collected every 6-12 months during TDF. Hazard ratios (HRs) assessing the association between qHBcrAg/qAnti-HBc and transitions from none/mild/significant fibrosis to advanced fibrosis/cirrhosis (progression) and from advanced fibrosis/cirrhosis to none/mild/significant fibrosis (regression) were estimated using a time-homogeneous Markov model. RESULTS: At baseline, advanced liver fibrosis/cirrhosis was observed in 40 (26%) patients. During a median follow-up of 48 months (interquartile range, 31-90), 38 transitions of progression (IR = 7/100 person-years) and 34 transitions of regression (IR = 6/100 person-years) were observed. Baseline levels of qHBcrAg and qAnti-HBc were not associated with liver fibrosis progression (adjusted-HR per log10 U/mL = 1.07, 95% confidence interval [CI] = 0.93-1.24; adjusted-HR per log10 Paul-Ehrlich-Institute [PEI] U/mL = 0.85, 95% CI = 0.70-1.04, respectively) or regression (adjusted-HR per log10 U/mL = 1.17, 95% CI = 0.95-1.46; adjusted-HR per log10 PEI U/mL = 0.97, 95% CI = 0.78-1.22, respectively) after adjusting for age, gender, duration of antiretroviral therapy, protease inhibitor-containing antiretroviral therapy, and CD4+/CD8+ ratio. Nevertheless, changes from the previous visit of qAnti-HBc levels were associated with liver fibrosis regression (adjusted-HR per log10 PEIU/mL change = 5.46, 95% CI = 1.56-19.16). CONCLUSIONS: Baseline qHBcrAg and qAnti-HBc levels are not associated with liver fibrosis evolution in TDF-treated HIV-HBV coinfected patients. The link between changes in qAnti-HBc levels during follow-up and liver fibrosis regression merits further study.

Diagnostic Accuracy of Noninvasive Markers of Steatosis, NASH, and Liver Fibrosis in HIV-Monoinfected Individuals at Risk of Nonalcoholic Fatty Liver Disease (NAFLD): Results From the ECHAM Study.

BACKGROUND: HIV-monoinfected individuals are at high risk of nonalcoholic fatty liver disease. Noninvasive tests of steatosis, nonalcoholic steatohepatitis (NASH), and fibrosis have been poorly assessed in this population. Using liver biopsy (LB) as a reference, we assessed the accuracy of noninvasive methods for their respective diagnosis: magnetic resonance imaging proton-density-fat-fraction (MRI-PDFF), FibroScan/controlled attenuation parameter (CAP), and biochemical tests. METHODS: We enrolled antiretroviral therapy-controlled participants with persistently elevated transaminases and/or metabolic syndrome, and/or lipodystrophy. All had hepatic MRI-PDFF, FibroScan/CAP, FibroTest/NashTest/SteatoTest, APRI, FIB-4, and nonalcoholic fatty liver disease-fibrosis score. A LB was indicated if suspected significant fibrosis (FibroScan ≥7.1 kPa and/or FibroTest ≥0.49). Performance was considered as good if area under a receiver operating characteristic curves (AUROCs) was >0.80. RESULTS: Among the 140 patients with suspected significant fibrosis out of the 402 eligible patients, 49 had had a LB: median age of 54 years (53-65), body mass index: 26 kg/m (24-30), steatosis in 37 (76%), NASH in 23 (47%), and fibrosis in 31 (63%) patients [F2: 7 (14%); F3: 6 (12%); and F4: 2 (4%)]. Regarding steatosis, MRI-PDFF had excellent and CAP good performances with AUROCs at 0.98 (95% confidence interval: 0.96 to 1.00) and 0.88 (0.76 to 0.99), respectively, whereas the AUROCs of SteatoTest was 0.68 (0.51 to 0.85). Regarding fibrosis (≥F2), APRI and FIB-4 had good performance with AUROCs at 0.86 (0.74 to 0.98) and 0.81 (0.67 to 0.95). By contrast, FibroScan and FibroTest had poor AUROCs [0.61 (0.43 to 0.79) and 0.61 (0.44 to 0.78)], with very low specificity. Regarding NASH, alanine aminotransferase ≥36 IU/L had good performance with AUROCs of 0.83 (0.71 to 0.94), whereas the NashTest had an AUROC of 0.60 (0.44 to 0.76). CONCLUSIONS: In HIV-monoinfected patients, MRI-PDFF and FibroScan/CAP are highly accurate for the diagnosis of steatosis. The alanine aminotransferase level and APRI should be considered for the detection of NASH and fibrosis.

Testing for hepatitis B virus alone does not increase vaccine coverage in non-immunized persons.

AIM: To determine whether hepatitis B virus (HBV)-testing could serve as a gateway to vaccinate non-immunized individuals in a low-prevalent country. METHODS: Non-immunized subjects participating in a multi-center, HBV-testing campaign in Paris, France were identified and contacted via telephone 3-9 mo after testing in order to determine vaccination status. Vaccination coverage was evaluated in per-protocol (for all respondents) and intent-to-treat analysis (assuming all non-responders did not vaccinate). RESULTS: In total, 1215/4924 (24.7%) enrolled subjects with complete HBV serology were identified as non-immunized and eligible for analysis. There were 99/902 successfully contacted subjects who had initiated HBV vaccination after screening: per-protocol, 11.0% (95%CI: 9.0-13.2); intent-to-treat, 8.2% (95%CI: 6.7-9.8). In multivariable analysis, vaccination was more likely to be initiated in individuals originating from moderate or high HBV-endemic countries (P < 0.001), patients with limited healthcare coverage (P = 0.01) and men who have sex with men (P = 0.02). When asked about the reasons for not initiating HBV vaccination, the most frequent response was "will be vaccinated later" (33.4%), followed by "did not want to vaccinate" (29.8%), and "vaccination was not proposed by the physician" (21.5%). Sub-group analysis indicated a stark contrast in vaccination coverage across centers, ranging from 0%-56%. CONCLUSION: HBV-vaccination after HBV screening was very low in this study, which appeared largely attributed to physician-patient motivation towards vaccination. Increased vaccination coverage might be achieved by emphasizing its need at the organizational level.

Renal outcomes after up to 8 years of tenofovir exposure in HIV-HBV-coinfected patients.

BACKGROUND: Renal toxicity is a common side effect during tenofovir (TDF)-use in HIV-infected, but not necessarily HBV-infected, patients. Nevertheless, little is known regarding TDF-use on renal impairment during HIV-HBV coinfection. We aimed to evaluate the progression and determinants of renal impairment in coinfected patients undergoing TDF. METHODS: A total of 175 coinfected patients initiating TDF-containing antiretroviral therapy were prospectively followed. Estimated glomerular filtration rates (eGFR) were calculated at baseline and every 6-12 months. Determinants of eGRF change from baseline (ΔeGFR) were evaluated using mixed-effect linear regression and progression towards renal impairment using proportional-hazards regression. RESULTS: At baseline, average eGFR was 96.7 ml/min per 1.73m2 (95% CI 93.8, 99.6). During a median 58.3 months (IQR 33.7-92.1) of treatment, eGFR decreased a monthly average of -0.14 ml/min per 1.73m2 (95% CI -0.16, -0.12). Significantly faster ΔeGFR was associated with baseline eGFR>90 (P=0.002), male gender (P=0.04), previous AIDS-defining illness at baseline (P=0.03), baseline liver cirrhosis (P=0.03) and concomitant protease inhibitor use (P=0.005). Between respective baseline and end of follow-up visits, the proportion of patients with renal impairment increased: normal function, 65.7% to 53.1%; mild impairment, 32.6% to 40.0%; moderate impairment, 1.7% to 6.9%. Higher age (P=0.01) and previous AIDS-defining illness (P=0.02) at baseline were independent risk-factors for developing impairment, while undetectable HBV DNA on-treatment was protective (P=0.006). Five (2.9%) patients permanently discontinued TDF after a renal event. CONCLUSIONS: Severe HIV-related and HBV-related morbidity negatively affects renal function in coinfected patients undergoing long-term TDF. Although most patients only developed mild/moderate impairment, close renal monitoring is warranted for this particular population.

Liver fibrosis regression and progression during controlled hepatitis B virus infection among HIV-HBV patients treated with tenofovir disoproxil fumarate in France: a prospective cohort study.

INTRODUCTION: Long-term tenofovir disoproxil fumarate (TDF) use has been associated with significant regression of liver fibrosis during hepatitis B virus (HBV) mono-infection, yet little is known during HIV-HBV coinfection. The aim of this study was to evaluate the evolution of liver fibrosis and its determinants in TDF-treated coinfected patients. METHODS: In this prospective cohort study, 167 HIV-HBV-infected patients initiating TDF-containing antiretroviral therapy were included. Fibrosis was assessed using the FibroTest® at baseline and every six to twelve months. Risk factors for fibrosis progression (F0-F1-F2 to F3-F4) and regression (F3-F4 to F0-F1-F2) were evaluated. RESULTS: At baseline, 134 (80.2%) patients had detectable HBV-DNA (median = 4.93 log10 IU/mL, IQR = 2.94-7.15) and 104 (62.3%) had hepatitis B "e" antigen-positive serology. Median follow-up was sixty months (IQR = 36-93). In the 47 (28.1%) patients with F3-F4 baseline fibrosis, 7/47 (14.9%) regressed to F0-F1-F2 at last follow-up visit. Fibrosis regression was significantly associated with higher CD4+ cell counts (P = 0.009) and lower fasting triglyceride levels (P = 0.007) at TDF-initiation. In the 120 (71.9%) patients with F0-F1-F2-baseline fibrosis, 20/120 (16.7%) progressed to F3-F4 at last follow-up visit. Fibrosis progression was associated with male gender (P = 0.01), older age (P = 0.001), from low/moderate HBV-endemic country (P = 0.007), lower nadir CD4+ cell count (P = 0.03), higher fasting glycaemia (P = 0.03) and anaemia (P = 0.004) at TDF-initiation. Control of HBV replication at end of follow-up was extensive (88.1%), while no HBV-related factors emerged as predictors of progression/regression. Incidence of severe liver-related events was low (n = 4, rate = 0.5/100 person-years). CONCLUSION: Liver fibrosis levels are stable for most coinfected patients undergoing TDF, despite control of HBV replication. Nevertheless, a concerning amount of liver fibrosis progression did occur, which could be partly explained by metabolic abnormalities and past severe immunosuppression and requires further evaluation.

Effectiveness of hepatitis B rapid tests toward linkage-to-care: results of a randomized, multicenter study.

OBJECTIVES: Worldwide, many infected individuals are unaware of their hepatitis B virus (HBV) status. We evaluated the effectiveness of HBV rapid testing in promoting linkage-to-care. METHODS: In 2012, volunteers were recruited from five Parisian centers. Participants were randomized 1 : 1 to receive standard serology (S) or rapid testing (VIKIA-HBsAg/Quick Profile anti-HBsAb) with confirmatory serology (R+S). The primary endpoint was percentage of individuals with appropriate linkage-to-care (nonimmunized individuals starting vaccination or HBsAg-positive individuals receiving medical evaluation). The secondary outcomes were percentage receiving HBV-test results and performance of HBV rapid tests. RESULTS: In total, 995 individuals were screened. Among the HBV-infection groups included in the primary endpoint (n=409), 20 (4.9%) received appropriate linkage-to-care, with no difference between S and R+S groups (5.7 vs. 4.1%, P=0.5). Two of eight HBsAg-positive participants had a medical visit (1/6 and 1/2 in the S and R+S groups, respectively) and 18/401 (4.5%) nonimmunized participants initiated HBV-vaccination (11/205 and 7/196). Factors that tended to be associated with linkage-to-care were female sex, birth country of high HBV prevalence, and extended medical stay. Test results were not obtained in 4.7% of participants, which was significantly higher in the S arm (P=0.02). Both sensitivity and specificity were 100% for the VIKIA-HBsAg rapid test and 94.4 and 80.8%, respectively, for the anti-HBsAb Quick Profile rapid test. CONCLUSION: Despite a higher proportion of participants obtaining their results in the R+S arm and better performance of anti-HBsAb rapid tests than described previously, we found no evidence that HBV screening based initially on rapid tests leads to increased HBV-vaccination rates or medical evaluation. This strategy should be evaluated in more hard-to-reach populations.
