The effect of weight gain and metabolic dysfunction-associated steatotic liver disease on liver fibrosis progression and regression in people with HIV.

OBJECTIVE: People with HIV (PWH) have high risk of liver fibrosis. We investigated the effect of weight gain and metabolic dysfunction-associated steatotic liver disease (MASLD) on liver fibrosis dynamics. DESIGN: Multicenter cohort study. METHODS: Fibrosis progression was defined as development of significant fibrosis (liver stiffness measurement [LSM]≥8 kPa), or transition to cirrhosis (LSM≥13 kPa), for those with significant fibrosis at baseline. Fibrosis regression was defined as transition to LSM<8 kPa, or to LSM<13 kPa for those with cirrhosis at baseline. MASLD was defined as hepatic steatosis (controlled attenuation parameter >248 dB/m) with at least one metabolic abnormality. A continuous-time multi-state Markov model was used to describe transitions across fibrosis states. RESULTS: Among 1183 PWH included from three centres (25.2% with viral hepatitis coinfection), baseline prevalence of significant fibrosis and MASLD was 14.4% and 46.8%, respectively. During a median follow-up of 2.5 years (interquartile range 1.9-3.5) the incidence rate of fibrosis progression and regression was 2.8 (95% CI, 2.3-3.4) and 2.2 (95% CI, 1.9-2.6) per 100 person-years, respectively. In Markov model, weight gain increased the odds of fibrosis progression (odds ratio [OR] 3.11, 95% CI 1.59-6.08), whereas weight gain (OR 0.30, 95% CI 0.10-0.84) and male sex (OR 0.32, 95% CI 0.14-0.75) decreased the odds of fibrosis regression. On multivariable Cox regression analysis, predictors of fibrosis progression were weight gain (adjusted hazard ratio [aHR] 3.12, 95% CI 1.41-6.90) and MASLD (aHR 2.72, 95% CI 1.05-7.02). CONCLUSIONS: Fibrosis transitions are driven by metabolic health variables in PWH, independently of viral hepatitis coinfection and antiretroviral class therapy.

Torque Teno Virus load is associated with CDC stage and CD4+ cell count in people living with HIV but unrelated to AIDS-defining events and Human Pegivirus load.

BACKGROUND: Torque Teno Virus (TTV) is a non-enveloped, circular single-strand DNA virus and part of the human virome. The replication of TTV was related to the immune status in patients treated with immunosuppressive drugs after organ transplantation. We hypothesize that TTV load could be an additional marker for immune function in people living with HIV (PLWH). METHODS: In this analysis serum samples of PLWH from the RESINA multicenter cohort were reanalysed for TTV. Investigated clinical and epidemiological parameters included Pegivirus (HPgV) load, age, sex, HIV load, CD4+ cell count (CDC 1, 2, 3) and CDC clinical stages (1993 CDC classification system, A, B, C) before initiation of antiretroviral treatment. Regression analysis was used to detect possible associations among parameters. RESULTS: Our analysis confirmed TTV as a strong predictor of CD4+ cell count and CDC class 3. This relationship was used to propose a first classification of TTV load in regard to clinical stage. We found no association with clinical CDC stages A, B and C. HPgV load was inversely correlated with HIV load but not TTV load. CONCLUSIONS: TTV load was associated with immunodeficiency in PLWH. Neither TTV- nor HIV load were predictive for the clinical categories of HIV infection.

Recommendations for defining preventable HIV-related mortality for public health monitoring in the era of Getting to Zero: an expert consensus.

Getting to Zero is a commonly cited strategic aim to reduce mortality due to both HIV and avoidable deaths among people with HIV. However, no clear definitions are attached to these aims with regard to what constitutes HIV-related or preventable mortality, and their ambition is limited. This Position Paper presents consensus recommendations to define preventable HIV-related mortality for a pragmatic approach to public health monitoring by use of national HIV surveillance data. These recommendations were informed by a comprehensive literature review and agreed by 42 international experts, including clinicians, public health professionals, researchers, commissioners, and community representatives. By applying the recommendations to 2019 national HIV surveillance data from the UK, we show that 30% of deaths among people with HIV were HIV-related or possibly HIV-related, and at least 63% of these deaths were preventable or potentially preventable. The application of these recommendations by health authorities will ensure consistent monitoring of HIV elimination targets and allow for the identification of inequalities and areas for intervention.

COVID-19 therapies for inpatients: a review and quality assessment of clinical guidelines.

Owing to condensed development processes, expanding evidence and differences in healthcare system characteristics, many COVID-19 guidelines differ in their quality and treatment recommendations, which has consequences for clinical practice. This review aimed to identify COVID-19 treatment guidelines, assess their quality and summarise their recommendations. Guidelines were identified for five therapies most commonly used among inpatients with COVID-19 (remdesivir, dexamethasone, tocilizumab, baricitinib and casirivimab/imdevimab) from 11 countries. Guideline quality was assessed using the Appraisal of Guidelines for Research and Evaluation II (AGREE-II) tool. Full details of recommendations and supporting evidence were analysed for high-quality guidelines, defined as those scoring ≥50% in Domain 3 (Rigour of Development) of AGREE-II. Overall, guidelines differed substantially in their quality and, even among high-quality guidelines using the same evidence, recommendations regarding specific therapeutics varied. Potential reasons for this heterogeneity, including the availability and consistency of clinical data, visibility of trial end-points and context-specific factors, are discussed.

Use of Systemic Therapies for Treatment of Psoriasis in People Living with Controlled HIV: Inference-Based Guidance from a Multidisciplinary Expert Panel.

BACKGROUND: People living with human immunodeficiency virus (PLHIV) have a similar prevalence of psoriasis as the general population, though incidence and severity correlate with HIV viral load. Adequately treating HIV early renders the infection a chronic medical condition and allows PLHIV with a suppressed viral load (PLHIV-s) to live normal lives. Despite this, safety concerns and a lack of high-level data have hindered the use of systemic psoriasis therapies in PLHIV-s. OBJECTIVES: We aim to provide a structured framework that supports healthcare professionals and patients discussing the risks and benefits of systemic psoriasis therapy in PLHIV-s. Our goal was to address the primary question, are responses to systemic therapies for the treatment of psoriasis in PLHIV-s similar to those in the non-HIV population? METHODS: We implemented an inference-based approach relying on indirect evidence when direct clinical trial data were absent. In this instance, we reviewed indirect evidence supporting inferences on the status of immune function in PLHIV. Recommendations on systemic treatment for psoriasis in PLHIV were derived using an inferential heuristic. RESULTS: We identified seven indirect indicators of immune function informed by largely independent bodies of evidence: (1) functional assays, (2) vaccine response, (3) life expectancy, (4) psoriasis manifestations, (5) rate of infections, (6) rate of malignancies, and (7) organ transplant outcomes. CONCLUSIONS: Drug-related benefits and risks when treating a patient with systemic psoriasis therapies are similar for non-HIV patients and PLHIV with a suppressed viral load and normalized CD4 counts. Prior to initiating psoriasis treatment in PLHIV, HIV replication should be addressed by an HIV specialist. Exercise additional caution for patients with a suppressed viral load and discordant CD4 responses on antiretroviral therapy.

People living with human immunodeficiency virus (PLHIV) develop psoriasis as often as everyone else. We asked: what are effective and safe treatments when PLHIV need systemic therapy (pills or injections) for their psoriasis?HIV infection attacks the immune system. When HIV is not treated, the immune system declines. A less effective immune system makes it harder for the body to fight infections and certain cancers. Psoriasis is a skin condition caused by overactive immune cells. Effective psoriasis treatments reduce immune-cell activity. There are some concerns that treatments for psoriasis may not work and could worsen infections or cancers.To answer the question, we gathered 11 dermatologists and 4 HIV specialists. We reviewed the international scientific literature on PLHIV and psoriasis. The absence of direct evidence and volume of information to review made the process challenging. The end results were worthwhile.We concluded that people who are diagnosed early and take antiretroviral therapy to control their HIV infection (PLHIV-c) can live long, healthy lives. Accordingly, we determined that PLHIV-c can likely expect the same safety and efficacy for systemic psoriasis treatments as the general population. Treatment decisions should be made on a case-by-case basis through consultation with the patient and treating physician(s).Pillars of modern medicine are evidence-based care and collaborative decision-making. Too often, neither care provider nor patient are adequately informed. We have tried to fill one information gap for PLHIV and psoriasis. This process may help answer questions in other disease populations where direct evidence is scarce or absent.

[HIV Test in Pregnancy - 100% Not Reached in 2020]. / HIV-Test in der Schwangerschaft ­ 2020 noch nicht bei 100.

INTRODUCTION: In 2019 38 million people were living with HIV worldwide, more than half of them girls and women. Knowledge about maternal HIV status enables HIV transmission prophylaxis, reducing mother-to-child transmission<1%. We aimed to investigate the implementation of the mandatory documentation of counseling and optional HIV testing in the maternity records as recommended in the German maternity guidelines. METHODS: In the Obstetric Department of the University Hospital Bonn, maternity records were reviewed from June to October 2020, and pregnant women were interviewed regarding the patients' recall of counseling and HIV testing as well as their attitude towards a universal screening strategy using an anonymous questionnaire. RESULTS: Documentation was incomplete in 11% of maternal records: in 8% there was neither documentation of counseling nor of HIV testing, in 3% documentation of counseling only. In 291 questionnaires 47% of pregnant women could not recall counselling. 90% of pregnant women were in favor of universal HIV testing in pregnancy, 9% were undecided, and 1% opposed it. 55% would support change from an "opt-in" to an "opt-out" screening policy in pregnancy. SUMMARY: Documentation of counseling and HIV testing was incomplete in 11% of cases, and nearly half of the women could not recall counselling. New strategies from midwives and obstetricians need to be developed to achieve universal HIV testing in pregnant women leading to zero HIV mother-to-child transmissions.

High Sustained Virologic Response Rates of Glecaprevir/Pibrentasvir in Patients With Dosing Interruption or Suboptimal Adherence.

INTRODUCTION: Pangenotypic, all-oral direct-acting antivirals, such as glecaprevir/pibrentasvir (G/P), are recommended for treatment of hepatitis C virus (HCV) infection. Concerns exist about the impact on efficacy in patients with suboptimal adherence, particularly with shorter treatment durations. These post hoc analyses evaluated adherence (based on pill count) in patients prescribed 8- or 12-week G/P, the impact of nonadherence on sustained virologic response at post-treatment week 12 (SVR12), factors associated with nonadherence, and efficacy in patients interrupting G/P treatment. METHODS: Data were pooled from 10 phase 3 clinical trials of treatment-naive patients with HCV genotype 1-6 without cirrhosis/with compensated cirrhosis (treatment adherence analysis) and 13 phase 3 clinical trials of all patients with HCV (interruption analysis). RESULTS: Among 2,149 patients included, overall mean adherence was 99.4%. Over the treatment duration, adherence decreased (weeks 0-4: 100%; weeks 5-8: 98.3%; and weeks 9-12: 97.1%) and the percentage of patients with ≥80% or ≥90% adherence declined. SVR12 rate in the intention-to-treat (ITT) population was 97.7% (modified ITT SVR12 99.3%) and remained high in nonadherent patients in the modified ITT population (<90%: 94.4%-100%; <80%: 83.3%-100%). Psychiatric disorders were associated with <80% adherence, and shorter treatment duration was associated with ≥80% adherence. Among 2,902 patients in the interruption analysis, 33 (1.1%) had a G/P treatment interruption of ≥1 day, with an SVR12 rate of 93.9% (31/33). No virologic failures occurred. DISCUSSION: These findings support the impact of treatment duration on adherence rates and further reinforce the concept of "treatment forgiveness" with direct-acting antivirals.

Changes in weight and BMI with first-line doravirine-based therapy.

OBJECTIVE: To evaluate changes in weight and BMI in adults with HIV-1 at 1 and 2 years after starting an antiretroviral regimen that included doravirine, ritonavir-boosted darunavir, or efavirenz. DESIGN: Post-hoc analysis of pooled data from three randomized controlled trials. METHODS: We evaluated weight change from baseline, weight gain at least 10%, and increase in BMI after 48 and 96 weeks of treatment with doravirine, ritonavir-boosted darunavir, or efavirenz-based regimens. Risk factors for weight gain and metabolic outcomes associated with weight gain were also examined. RESULTS: Mean (and median) weight changes were similar for doravirine [1.7 (1.0) kg] and ritonavir-boosted darunavir [1.4 (0.6) kg] and were lower for efavirenz [0.6 (0.0) kg] at week 48 but were similar across all treatment groups at week 96 [2.4 (1.5), 1.8 (0.7), and 1.6 (1.0) kg, respectively]. No significant differences between treatment groups were found in the proportion of participants with at least 10% weight gain or the proportion with BMI class increase at either time point. Low CD4 T-cell count and high HIV-1 RNA at baseline were associated with at least 10% weight gain and BMI class increase at both timepoints, but treatment group, age, sex, and race were not. CONCLUSION: Weight gains over 96 weeks were low in all treatment groups and were similar to the average yearly change in adults without HIV-1. Significant weight gain and BMI class increase were similar across the treatment groups and were predicted by low baseline CD4 T-cell count and high baseline HIV-1 RNA.

Influence of Hepatitis C Coinfection and Treatment on Risk of Diabetes Mellitus in HIV-Positive Persons.

BACKGROUND: The role of hepatitis C virus (HCV) coinfection and HCV-RNA in the development of diabetes mellitus (DM) in HIV-positive persons remains unclear. METHODS: Poisson regression was used to compare incidence rates of DM (blood glucose >11.1 mmol/L, HbA1C >6.5% or >48 mmol/mol, starting antidiabetic medicine or physician reported date of DM onset) between current HIV/HCV groups (anti-HCV-negative, spontaneously cleared HCV, chronic untreated HCV, successfully treated HCV, HCV-RNA-positive after HCV treatment). RESULTS: A total of 16 099 persons were included; at baseline 10 091 (62.7%) were HCV-Ab-negative, 722 (4.5%) were spontaneous clearers, 3614 (22.4%) were chronically infected, 912 (5.7%) had been successfully treated, and 760 (4.7%) were HCV-RNA-positive after treatment. During 136 084 person-years of follow-up (PYFU; median [interquartile range], 6.9 [3.6-13.2]), 1108 (6.9%) developed DM (crude incidence rate, 8.1/1000 PYFU; 95% CI, 7.7-8.6). After adjustment, there was no difference between the 5 HCV strata in incidence of DM (global P = .33). Hypertension (22.2%; 95% CI, 17.5%-26.2%) and body mass index >25 (22.0%; 95% CI, 10.4%-29.7%) had the largest population-attributable fractions for DM. CONCLUSIONS: HCV coinfection and HCV cure were not associated with DM in this large study. The biggest modifiable risk factors were hypertension and obesity, and continued efforts to manage such comorbidities should be prioritized.

Reinfection With the Hepatitis C Virus in Men Who Have Sex With Men After Successful Treatment With Direct-acting Antivirals in Germany: Current Incidence Rates, Compared With Rates During the Interferon Era.

BACKGROUND: Micro-elimination of the hepatitis C virus (HCV) includes treatment in populations at risk of ongoing HCV transmission, such as men who have sex with men (MSM) or people who inject drugs (PWID). We analyzed the HCV reinfection incidence rates of participants in the German hepatitis C cohort (GECCO) and compared our data to previous findings from the interferon era. METHODS: Patients with HCV reinfections in the multi-centric GECCO cohort were compared to patients in whom no reinfection occurred. The HCV reinfection incidence rate in MSM was also compared to the incidence rate in the interferon era (using data from the European Acquired Immunodeficiency Syndrome Treatment Network [NEAT]). RESULTS: Between January 2014 and April 2018, 48 HCV reinfections occurred in 2298 individuals (2%), with 2346 cured HCV episodes. The median time to reinfection was 500 days (range 16-1160) and the overall HCV reinfection incidence rate was 1.89 per 100 person-years (py; 95% confidence interval [CI], 1.41-2.48). In a multivariate analysis, the transmission risk in MSM was the only independent risk factor of HCV reinfection (odds ratio, 39.3; 95% CI, 4.57-334.40; P = .001). The incidence rate in MSM was 9.02 (95% CI, 6.48-12.26) per 100 py, compared to 1.14 per 100 py in PWID (95% CI, .56-2.09). The incidence rate for a first HCV reinfection in MSM was similar in the direct-acting antiviral era, compared to the interferon era, with a hazard ratio of 1.05 (95% CI, .64-1.74; P = .831). CONCLUSIONS: HCV reinfection remains a frequent finding among MSM in Germany. In addition to behavioral interventions, early HCV treatment and retreatment should be implemented for this subgroup to prevent HCV transmission.

[Treatment of HIV in Pregnancy - Progress Over One Decade]. / Behandlung von HIV in der Schwangerschaft ­ Entwicklung über eine Dekade.

INTRODUCTION: Worldwide, 37 million people are infected with HIV; more than 50% are women. Currently, MTCT (mother-to-child transmission) can be reduced to<1%. The intention of the present study was to analyze the development of (1) the course of pregnancy of HIV-infected women, (2) the mode of delivery and (3) the post-exposure prophylaxis of the newborn over the last decade. METHODOLOGY: In this retrospective study, data from HIV-infected women who between 2005 and 2016 received care at the HIV outpatient department and gave birth at the Department of Obstetrics at University Hospital Bonn was analyzed. Furthermore, neonatal data was collected and HIV-MTCT was evaluated. RESULTS: In the 2005-2016 study period, 87 pregnancies in 61 women were identified. Seventy babies were born alive at the Department of Obstetrics, University Hospital Bonn. 53% of these women were of African origin. The median of CD4+ cell count was 510 cells/ml (IQR 444); however, 32 women (52%) had more than 500 cells/ml. During the antenatal period, the HI viral load had been suppressed completely in 77% of women (<50 HIV-1-RNA copies/ml) and was<400 HIV-1-RNA copies/ml in 92% of women. The elective cesarean section rate fell significantly from 77% in the years 2005-2011 to 58% in 2012-2016. The proportion of deliveries after 37 weeks of gestation increased markedly from 60% to 69% after 2012. Additionally, while between 2005-2011 the birth weight of 78% of the newborns was between the 10th and 90th percentile, this proportion increased to 92% after 2012. Fifty-four of 70 newborns (77%) were classified as having low to normal HIV transmission risk. A vertical HIV transmission from mother to child did not occur (0/70). CONCLUSIONS: Between 2005 and 2016 no vertical HIV transmission from mother to child occurred (0/70). Due to the change in treatment strategy, the elective cesarean section rate fell significantly as well the rate of premature births. An optimal interdisciplinary collaboration builds the basis for successful treatment of HIV in pregnancy.

Benefit of Early versus Deferred Antiretroviral Therapy on Progression of Liver Fibrosis among People with HIV in the START Randomized Trial.

The role of antiretroviral therapy (ART) in reducing or contributing to liver fibrosis in persons with human immunodeficiency virus (HIV) is unclear. We evaluated participants in the Strategic Timing of AntiRetroviral Treatment (START) trial for liver fibrosis using the AST to Platelet Ratio Index (APRI) and Fibrosis-4 Index (FIB-4), and assessed for a benefit of early versus delayed ART on liver fibrosis progression. ART-naïve persons with high CD4 counts (>500 cells/µL) from 222 clinical sites in 35 countries were randomized to receive ART either at study enrollment (immediate treatment arm) or when their CD4 count fell below 350 cells/µL (deferred treatment arm). The following outcomes were evaluated: fibrosis (APRI > 0.5 or FIB-4 > 1.45), significant fibrosis (APRI > 1.5 or FIB-4 > 3.25), hepatic flare, and resolution of elevated APRI and FIB-4 scores. Of the 4,684 enrolled into the START study, 104 did not have APRI or FIB-4 results and were excluded. Among 4,580 participants (2,273 immediate treatment; 2,307 deferred treatment), the median age was 36 years, 26.9% were female, and 30.4% were black. Three percent had an alcoholism or substance abuse history, 6.4% had hepatitis B and/or C, and 1.1% had significant fibrosis at baseline. The median CD4 count was 651, and 5.3% had HIV RNA ≤ 200. Immediate arm participants were at lower risk of developing increased fibrosis scores than deferred arm participants (hazard ratio [HR] = 0.66; 95% confidence interval [CI] = 0.57-0.78; P < 0.001) and more likely to have resolution of elevated baseline scores (HR 1.6; 95% CI 1.3-1.9; P < 0.001). Conclusions: Significant liver fibrosis was rare among ART-naïve HIV-positive persons with high CD4 counts. Our findings suggest a benefit of early ART in preventing the development of liver fibrosis.

Hepatic safety of maraviroc in patients with HIV-1 and hepatitis C and/or B virus: 144-week results from a randomized, placebo-controlled trial.

BACKGROUND: In the primary 48-week analysis of a hepatic safety trial in patients with HIV-1 coinfected with HBV and/or HCV, maraviroc-containing treatment regimens were not associated with increased hepatotoxicity. METHODS: In this randomized, double-blind, placebo-controlled, multicentre study, patients received maraviroc twice daily (n=70) or placebo (n=67) with concomitant antiretroviral therapy for 144 weeks (Clinicaltrials.gov identifier, NCT01327547). The primary end point was the proportion of patients with protocol-defined Grade 3/4 alanine aminotransferase (ALT) abnormalities through week 48. Key secondary end points included 144-week analysis of Grade 3/4 ALT abnormalities and liver fibrosis by enhanced liver fibrosis (ELF) testing, hepatic elastography and an optional biopsy substudy. RESULTS: Through 144 weeks of treatment, two (maraviroc) and three (placebo) patients met the protocol-defined Grade 3/4 ALT end point. Similar to the 48-week results, there were no statistically significant differences between groups in change from baseline in ELF or hepatic elastography. However, decreased elastography scores were noted in the maraviroc group. Blinded pathologist review suggested that 2 of 11 paired biopsies (both on maraviroc) showed signs of decreased fibrosis. One (maraviroc) and two (placebo) patients experienced treatment-related hepatobiliary adverse events (AEs). Five patients in the maraviroc group discontinued because of treatment-related AEs versus three in the placebo group. One death in the maraviroc group and two deaths in the placebo group were reported. CONCLUSIONS: Use of maraviroc did not increase hepatotoxicity in this population through 144 weeks. Further investigation regarding possible beneficial effects of maraviroc on liver fibrosis may be warranted.

Effect of antiviral therapy for HCV on lipid levels.

BACKGROUND: HCV has complex interactions with human lipid metabolism leading to down regulation of cholesterol levels. Interferon (IFN) therapy has been shown to decrease cholesterol even further. With the availability of second-generation direct-acting antiviral agents (DAA) the effect of suppressing and eliminating HCV on lipid metabolism warrants reevaluation. METHODS: Prospective German multicentre cohort on HCV- and HIV-HCV-infected patients treated with direct-antiviral agents (GECCO). Lipids were assessed at baseline, during and after therapy. Wilcoxon test corrected for multiple testing was used. RESULTS: For the analysis, 520 patients with chronic hepatitis C were available. Patients with chronic hepatitis C were treated as follows: sofosbuvir (SOF)/pegylated IFN (PEG-IFN)/ribavirin (RBV; HCV=34, HIV-HCV=36), SOF/RBV (HCV=47, HIV-HCV=16), SOF/simeprevir (HCV=9, HCV-HIV=2), SOF/daclatasvir +/- RBV (HCV=27, HIV-HCV=47), SOF/ledipasvir +/- RBV (HCV=147, HCV-HIV=100) and ombitasvir/paritaprevir/ritonavir +/- dasabuvir +/- RBV (2D, HCV=2, HCV-HIV=6; 3D, HCV=39, HCV-HIV=8). On treatment there was a statistically significant increase in total cholesterol for any IFN-free DAA regimen, which was maintained after end of therapy. Changes of total cholesterol were driven by changes in low-density lipoprotein cholesterol, whereas high-density lipoprotein cholesterol remained unchanged. In contrast, total cholesterol decreased on SOF/PEG-IFN/RBV and increased after end of therapy above baseline levels. Triglycerides increased during treatment with SOF/PEG-IFN/RBV, but not on DAA-only regimens. CONCLUSIONS: Suppressing and eliminating HCV with IFN-free DAA regimens increased cholesterol levels, but had no effect on triglycerides. In contrast IFN-based therapy decreased cholesterol and increased triglycerides during treatment and led to increases in cholesterol after achieving sustained virological response.

Liver-related death among HIV/hepatitis C virus-co-infected individuals: implications for the era of directly acting antivirals.

BACKGROUND: Potent, less toxic, directly acting antivirals (DAAs) for treatment of hepatitis C virus (HCV) infection promise to improve HCV cure rates among HIV/HCV-co-infected individuals. However, the costs of treatment will necessitate prioritization of those at greatest risk of liver-related death (LRD) for therapy. This study aims to provide guidance on who should be prioritized for DAA treatment. METHODS: Three thousand, nine hundred and forty-one HCV antibody-positive PSHREG and FIB-4 are names not acronyms (EuroSIDA) patients with follow-up after 1 January 2000 were included, with causes of death classified using Coding causes of Death in HIV (CoDe) methodology. Crude death rates, competing-risks Cox proportional-hazards models and cumulative incidence functions were used to describe factors associated with LRD. RESULTS: LRD accounted for 145 of 670 (21.6%) deaths in the study population. LRD rates peaked in those aged 35-45 years, and occurred almost exclusively in those with at least F2 fibrosis at baseline. In adjusted Cox models, risk factors for LRD included F4 or F2/F3 fibrosis [sub-distribution hazard ratio (sHR) 6.3, 95% confidence interval (CI) 4.1-9.6; and sHR 2.5, 95% CI 1.5-4.2 vs. F0/F1, respectively), CD4 cell count (sHR 0.83, 95% CI 0.73-0.95 per doubling) and hepatitis B surface antigen-positive (sHR 2.2, 95% CI 1.3-3.5 vs. hepatitis B surface antigen-negative). The 5-year probability of LRD was low in those with F0/F1 fibrosis (sHR 2.2%, 95% CI 1.7-2.9), but substantial in those with F2/F3 and F4 fibrosis (sHR 10.3%, 95% CI 7.6-13.5; and sHR 14.0%, 95% CI 10.3-18.3, respectively). CONCLUSION: Treatment with DAAs should be prioritized for those with at least F2 fibrosis. Early initiation of cART with the aim of avoiding low CD4 cell counts should be considered essential to decrease the risk of LRD and the need for HCV treatment.

Boceprevir or Telaprevir Based Triple Therapy against Chronic Hepatitis C in HIV Coinfection: Real-Life Safety and Efficacy.

BACKGROUND AND AIMS: Clinical trials of therapy against chronic hepatitis C virus (HCV) infection including boceprevir (BOC) or telaprevir (TVR) plus pegylated interferon and ribavirin (PR) have reported considerably higher response rates than those achieved with PR alone. This study sought to evaluate the efficacy and safety of triple therapy including BOC or TVR in combination with PR in HIV/HCV-coinfected patients under real-life conditions. METHODS: In a multicentre study conducted in 24 sites throughout five European countries, all HIV/HCV-coinfected patients who initiated a combination of BOC or TVR plus PR and who had at least 60 weeks of follow-up, were analyzed. Sustained virologic response 12 weeks after the scheduled end of therapy date (SVR12) and the rate of discontinuations due to adverse events (AE) were evaluated. RESULTS: Of the 159 subjects included, 127 (79.9%) were male, 45 (34.4%) were treatment-naïve for PR and 60 (45.4%) showed cirrhosis. SVR12 was observed in 31/46 (67.4%) patients treated with BOC and 69/113 (61.1%) patients treated with TVR. Overall discontinuations due to AE rates were 8.7% for BOC and 8% for TVR. Grade 3 or 4 hematological abnormalities were frequently observed; anemia 7%, thrombocytopenia 17.2% and neutropenia 16.4%. CONCLUSION: The efficacy and safety of triple therapy including BOC or TVR plus PR under real-life conditions of use in the HIV/HCV-coinfected population was similar to what is observed in clinical trials. Hematological side effects are frequent but manageable.

Hepatic safety in subjects with HIV-1 and hepatitis C and/or B virus: a randomized, double-blind study of maraviroc versus placebo in combination with antiretroviral agents.

BACKGROUND: One of the more clinically relevant co-morbidities in HIV-infected patients is the development of progressive liver disease due to hepatitis B virus (HBV) or hepatitis C virus (HCV). In addition, hepatotoxicity has been observed with prolonged use of antiretroviral agents. OBJECTIVE: To evaluate the hepatic safety of maraviroc in combination with other antiretroviral agents in HIV-1-infected subjects co-infected with HCV and/or HBV. METHODS: In this 148-week randomized, double-blind, placebo-controlled, multicentre study (NCT01327547), subjects received maraviroc twice daily (n = 70) or placebo (n = 67) in combination with other antiretroviral agents. PRIMARY ENDPOINT: the percentage at week 48 of subjects with Grade 3 and Grade 4 ALT abnormalities, defined as >5 × upper limit of normal (ULN) if baseline ALT ≤ ULN or >3.5 × baseline if baseline ALT>ULN in the maraviroc versus the placebo arm. RESULTS: At week 48, one subject in each group had met the primary endpoint definition. No subjects met protocol-defined liver stopping criteria and there were no cases of Hy's law or treatment-related hepatobiliary serious adverse events. No significant difference in change from baseline in enhanced liver fibrosis or hepatic elastography was observed between groups. Treatment-related hepatobiliary adverse events were reported in one and two subjects receiving maraviroc and placebo, respectively; discontinuations due to treatment-related AEs occurred in four and two subjects receiving maraviroc and placebo, respectively; two deaths were reported in the placebo group. CONCLUSIONS: The use of maraviroc does not increase hepatotoxicity in HIV-1-infected subjects co-infected with HCV and/or HBV through 48 weeks of treatment.

Increased incidence of antiretroviral drug discontinuation among patients with viremic hepatitis C virus coinfection and high hyaluronic acid, a marker of liver fibrosis.

BACKGROUND: Most antiretroviral drugs are metabolized by the liver; hepatic disease or liver damage as a result of hepatitis C virus (HCV) could impair this metabolism leading to an increased risk of drug toxicity. This study aimed to determine the risk of antiretroviral drug discontinuation among HCV/HIV coinfected patients. METHODS: EuroSIDA patients taking combination antiretroviral therapy were included. Poisson regression identified factors associated with antiretroviral treatment discontinuation. RESULTS: A total of 9535 HIV-positive patients with known HCV status were included (6939 HCVAb-negative; 2596 HCVAb-positive at baseline). Viremic HCV infection was associated with a 44% increased risk of antiretroviral drug discontinuation compared with aviremic infection [adjusted incidence rate ratio, aIRR: 1.44 (95% confidence interval, CI 1.22-1.69)]; this relationship was largest among nonnucleoside reverse transcriptase inhibitors [aIRR: 1.59 (95% CI 1.18-2.14)]. In the subset of 935 HIV-positive patients also HCV-positive or HBV-positive with plasma hyaluronic acid measured, hyaluronic acid more than 100 ng/ml was associated with a 37% increased risk of antiretroviral drug discontinuation [aIRR: 1.37 (95% CI 1.08-1.73) vs. hyaluronic acid ≤100 ng/ml] and the effect of HCV viremia became nonsignificant; the largest drug association was seen for protease inhibitors [aIRR: 1.40 (95% CI 1.04-1.89)]. CONCLUSION: HCV viremia and high levels of hyaluronic acid predict antiretroviral drug discontinuation. Evidence was also found to suggest a link between impaired liver function and protease inhibitor toxicity.

Variation in IFNL4 genotype and response to interferon-based therapy of hepatitis C in HIV-positive patients with acute and chronic hepatitis C.

The IFNL4 ss469415590 polymorphism has recently be shown to better predict treatment response in chronic hepatitis than the IL28B rs12979860 variant. However, no data exist in patients with HIV/hepatitis C virus (HCV) coinfection. Analysing 206 HCV(+)/HIV(+) and 162 HCV(+)/HIV(-) patients, we found that compared with IL28B rs12979860, IFNL4 ss469415590 was strongly associated with response to interferon/ribavirin therapy in HCV(+)/HIV(-) individuals but not in HIV(+)/HCV(+) patients. Thus, effects of the IFNL4 variant may differ in HIV(+) and HIV(-) patients.
