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 less than 8 kPa, or to LSM less than 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 multistate Markov model was used to describe transitions across fibrosis states. RESULTS: Among 1183 PWH included from three centers (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% confidence interval (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). CONCLUSION: 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 Centers for Disease Control and Prevention Stage and CD4+ Cell Count in People Living With Human Immunodeficiency Virus but Seems Unrelated to AIDS-Defining Events and Human Pegivirus Load.

BACKGROUND: Torque teno virus (TTV) is part of the human virome. TTV load was related to the immune status in patients 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 reanalyzed for TTV. Investigated clinical and epidemiological parameters included human pegivirus load, patient age and sex, HIV load, CD4+ T-cell count (Centers for Disease Control and Prevention [CDC] stage 1, 2, or 3), and CDC clinical stage (1993 CDC classification system; stage A, B, or C) before initiation of antiretroviral therapy. Regression analysis was used to detect possible associations among parameters. RESULTS: Our analysis confirmed TTV as a strong predictor of CD4+ T-cell count and CDC class 3. This relationship was used to propose a first classification of TTV load with regard to clinical stage. We found no association with clinical CDC stages A-C. The human pegivirus 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.

Direct-Acting Antiviral Therapy for Treatment of Acute and Recent Hepatitis C Virus Infection: A Narrative Review.

Following the discovery of hepatitis C virus (HCV) in 1989, 3 decades of basic, translational, and clinical research culminated in the development of direct-acting antiviral (DAA) therapy-curative oral treatment for HCV infection. The availability of DAA therapy revolutionized HCV clinical management, including acute (duration of infection <6 mo) and recent (duration of infection <12 mo) infection. Several DAA regimens, including the contemporary pan-genotypic combinations of sofosbuvir-velpatasvir and glecaprevir-pibrentasvir, have been shown to be safe and effective among people with acute and recent HCV infection, highlighting their potential in an HCV controlled human infection model. This article describes the natural history and management of acute and recent HCV infection in the era of DAA therapy and outlines a strategy for use of DAA therapies in the setting of an HCV controlled human infection model.

Hepatitis C virus transmission between eight high-income countries among men who have sex with men: a whole-genome analysis.

BACKGROUND: Microelimination of the hepatitis C virus (HCV) among men who have sex with men (MSM) could be complicated by continuous external introductions and the emergence of phylogenetic clusters harbouring clinically significant resistance-associated substitutions (RAS). To investigate international clustering and the prevalence and transmission of RAS, we aimed to analyse whole-genome HCV sequences from MSM with a recently acquired infection who participated in a large, international HCV treatment trial. METHODS: For this whole-genome analysis, we obtained HCV sequences from 128 MSM who had acquired HCV within the past 12 months and were participating in the REACT trial. The participants from whom sequences were obtained were recruited at 24 sites in eight countries. We inferred maximum-likelihood phylogenies and identified transmission clusters for HCV genotypes separately. We constructed time-scaled phylogenies to estimate cluster introduction dates and used a Bayesian Skygrid approach to estimate the effective population size over the past 50 years. We calculated the prevalence of RAS and the extent of RAS transmission in the study population. FINDINGS: The majority of recent HCV infections were part of international networks that arose in the late 1990s and early 2000s. Sequences obtained in the same country clustered frequently, and in 36% of subclusters since 2015 we found evidence of international transmission. European MSM were more likely than non-European MSM to be in a cluster (odds ratio 11·9 [95% CI 3·6-43·4], p<0·0001). The effective population size decreased rapidly since around 2015 in Europe. RAS associated with substantially diminished cure rates were infrequently detected and transmission of highly resistant viruses was not observed. INTERPRETATION: Despite antiviral treatment becoming widely available, international transmission of HCV among MSM has still occurred over the past 8 years, which could complicate microelimination of the virus in this population. RAS-enriched clusters and widespread RAS transmission are currently not a threat to elimination goals. These findings support an international approach for HCV microelimination among MSM.

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.

Monkeypox Virus Infection in Humans across 16 Countries - April-June 2022.

BACKGROUND: Before April 2022, monkeypox virus infection in humans was seldom reported outside African regions where it is endemic. Currently, cases are occurring worldwide. Transmission, risk factors, clinical presentation, and outcomes of infection are poorly defined. METHODS: We formed an international collaborative group of clinicians who contributed to an international case series to describe the presentation, clinical course, and outcomes of polymerase-chain-reaction-confirmed monkeypox virus infections. RESULTS: We report 528 infections diagnosed between April 27 and June 24, 2022, at 43 sites in 16 countries. Overall, 98% of the persons with infection were gay or bisexual men, 75% were White, and 41% had human immunodeficiency virus infection; the median age was 38 years. Transmission was suspected to have occurred through sexual activity in 95% of the persons with infection. In this case series, 95% of the persons presented with a rash (with 64% having ≤10 lesions), 73% had anogenital lesions, and 41% had mucosal lesions (with 54 having a single genital lesion). Common systemic features preceding the rash included fever (62%), lethargy (41%), myalgia (31%), and headache (27%); lymphadenopathy was also common (reported in 56%). Concomitant sexually transmitted infections were reported in 109 of 377 persons (29%) who were tested. Among the 23 persons with a clear exposure history, the median incubation period was 7 days (range, 3 to 20). Monkeypox virus DNA was detected in 29 of the 32 persons in whom seminal fluid was analyzed. Antiviral treatment was given to 5% of the persons overall, and 70 (13%) were hospitalized; the reasons for hospitalization were pain management, mostly for severe anorectal pain (21 persons); soft-tissue superinfection (18); pharyngitis limiting oral intake (5); eye lesions (2); acute kidney injury (2); myocarditis (2); and infection-control purposes (13). No deaths were reported. CONCLUSIONS: In this case series, monkeypox manifested with a variety of dermatologic and systemic clinical findings. The simultaneous identification of cases outside areas where monkeypox has traditionally been endemic highlights the need for rapid identification and diagnosis of cases to contain further community spread.

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.

Reduction of CD8 T Cell Functionality but Not Inhibitory Capacity by Integrase Inhibitors.

Although HIV-specific CD8 T cells are effective in controlling HIV infection, they fail to clear infection even in the presence of antiretroviral therapy (ART) and cure strategies such as "shock-and-kill." Little is known how ART is contributing to HIV-specific CD8 T cell function and the ability to clear HIV infection. Therefore, we first assessed the cytokine polyfunctionality and proliferation of CD8 T cells from ART-treated HIV+ individuals directly ex vivo and observed a decline in the multifunctional response as well as proliferation indices of these cells in individuals treated with integrase inhibitor (INSTI) based ART regimens compared to both protease inhibitor (PI) and nonnucleoside reverse transcriptase inhibitor (NNRTI) based regimens. We next cocultured CD8 T cells with different drugs individually and were able to observe reduced functional properties with significantly decreased ability of CD8 T cells to express IFN-γ, MIP1ß and TNF-α only after treatment with INSTI-based regimens. Furthermore, previously activated and INSTI-treated CD8 T cells demonstrated reduced capacity to express perforin and granzyme B compared to PI and NNRTI treated cells. Unexpectedly, CD8 T cells treated with dolutegravir showed a similar killing ability 7 dpi compared to emtricitabine or rilpivirine treated cells. We next used a live cell imaging assay to determine the migratory capacity of CD8 T cells. Only INSTI-treated cells showed less migratory activity after SDF-1α stimulation compared to NRTI regimens. Our data show that the choice of ART can have a significant impact on CD8 T cell effector functions, but the importance for potential eradication attempts is unknown. IMPORTANCE Integrase Strand Transfer Inhibitors (INSTI) are recommended by national and international guidelines as a key component of ART in the treatment of HIV infected patients. In particular, their efficacy, tolerability and low drug-drug interaction profile have made them to the preferred choice as part of the first-line regimen in treatment-naive individuals. Here, we demonstrate that the choice of ART can have a significant impact on function and metabolism of CD8 T cells. In summary, our study provides first evidence on a significant, negative impact on CD8 T cell effector functions in the presence of two INSTIs, dolutegravir and elvitegravir, which may contribute to the limited success of eradicating HIV-infected cells through "shock-and-kill" strategies. Although our findings are coherent with recent studies highlighting a possible role of dolutegravir in weight gain, further investigations are necessary to fully understand the impact of INSTI-based regimens on the health of the individual during antiretroviral therapy.

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.

Sofosbuvir/velpatasvir for 12 vs. 6 weeks for the treatment of recently acquired hepatitis C infection.

BACKGROUND & AIMS: Shortened duration therapy for acute and recent HCV infection has been shown to be highly effective in several small non-randomised studies with direct-acting antiviral regimens; however, large randomised studies are lacking. METHODS: REACT was an NIH-funded multicentre international, open-label, randomised, phase IV non-inferiority trial examining the efficacy of short course (6-week) vs. standard course (12-week) therapy with sofosbuvir-velpatasvir for recent HCV infection (estimated duration of infection ≤12 months). Randomisation occurred at week 6. The primary endpoint was sustained virological response 12 weeks after treatment end (SVR12) in the intention-to treat (ITT) population. A total of 250 participants were due to be enrolled, but on advice of the data safety and monitoring board the study was halted early. RESULTS: The primary analysis population consisted of 188 randomised participants at termination of study enrolment; short arm (n = 93), standard arm (n = 95). Ninety-seven percent were male and 69% HIV positive. ITT SVR12 was 76/93, 81.7% (95% CI 72.4-89.0) in the short arm and 86/95, 90.5% (95% CI 82.7-95.6) in the standard arm. The difference between the arms was -8.8 (95% CI -18.6 to 1.0). In modified ITT analysis, wherein non-virological reasons for failure were excluded (death, reinfection, loss to follow-up), SVR12 was 76/85, 89.4% (95% CI 80.8-95.0) in the short arm and 86/88, 97.7% in the standard arm (95% CI 92.0-99.7; difference -8.3%, p = 0.025). CONCLUSIONS: In this randomised study in recent HCV infection, a 6-week course of sofosbuvir-velpatasvir did not meet the criteria for non-inferiority to standard 12-week therapy. LAY SUMMARY: In this randomised trial, 188 people with recently acquired hepatitis C infection were randomly assigned to treatment using either a short 6-week course (93 people) or standard 12-week course (95 people) of the hepatitis C treatment sofosbuvir/velpatasvir. There were 9 cases of relapse after treatment with the short course and 2 following the standard course. A shortened course of 6-week therapy for hepatitis C infection appeared to be less effective than a standard 12-week course in people with recently acquired hepatitis C infection. CLINICALTRIALS.

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.

Prediction of Esophageal Varices by Liver Stiffness and Platelets in Persons With Human Immunodeficiency Virus Infection and Compensated Advanced Chronic Liver Disease.

BACKGROUND: People living with human immunodeficiency virus (PLWH) are at increased risk of cirrhosis and esophageal varices. Baveno VI criteria, based on liver stiffness measurement (LSM) and platelet count, have been proposed to avoid unnecessary esophagogastroduodenoscopy (EGD) screening for esophageal varices needing treatment (EVNT). This approach has not been validated in PLWH. METHODS: PLWH from 8 prospective cohorts were included if they fulfilled the following criteria: (1) compensated advanced chronic liver disease (LSM >10 kPa); (2) availability of EGD within 6 months of reliable LSM. Baveno VI (LSM <20 kPa and platelets >150 000/µL), expanded Baveno VI (LSM <25 kPa and platelets >110 000/µL), and Estudio de las Hepatitis Víricas (HEPAVIR) criteria (LSM <21 kPa) were applied to identify patients not requiring EGD screening. Criteria optimization was based on the percentage of EGDs spared, while keeping the risk of missing EVNT <5%. RESULTS: Five hundred seven PLWH were divided into a training (n = 318) and a validation set (n = 189). EVNT were found in 7.5%. In the training set, Baveno VI, expanded Baveno VI, and HEPAVIR criteria spared 10.1%, 25.5%, and 28% of EGDs, while missing 0%, 1.2%, and 2.2% of EVNT, respectively. The best thresholds to rule out EVNT were platelets >110 000/µL and LSM <30 kPa (HIV cirrhosis criteria), with 34.6% of EGDs spared and 0% EVNT missed. In the validation set, HEPAVIR and HIV cirrhosis criteria spared 54% and 48.7% of EGDs, while missing 4.9% and 2.2% EVNT, respectively. CONCLUSIONS: Baveno VI criteria can be extended to HEPAVIR and HIV cirrhosis criteria while sparing a significant number of EGDs, thus improving resource utilization for PLWH with compensated advanced chronic liver disease.

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.

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.

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.

Immediate Versus Deferred Switching From a Boosted Protease Inhibitor-based Regimen to a Dolutegravir-based Regimen in Virologically Suppressed Patients With High Cardiovascular Risk or Age ≥50 Years: Final 96-Week Results of the NEAT022 Study.

Background: Both immediate and deferred switching from a ritonavir-boosted protease inhibitor (PI/r)-based regimen to a dolutegravir (DTG)-based regimen may improve lipid profile. Methods: European Network for AIDS Treatment 022 Study (NEAT022) is a European, open-label, randomized trial. Human immunodeficiency virus (HIV)-infected adults aged ≥50 years or with a Framingham score ≥10% were eligible if HIV RNA was <50 copies/mL. Patients were randomized to switch from PI/r to DTG immediately (DTG-I) or to deferred switch at week 48 (DTG-D). Week 96 endpoints were proportion of patients with HIV RNA <50 copies/mL, percentage change of lipid fractions, and adverse events (AEs). Results: Four hundred fifteen patients were randomized: 205 to DTG-I and 210 DTG-D. The primary objective of noninferiority at week 48 was met. At week 96, treatment success rate was 92.2% in the DTG-I arm and 87% in the DTG-D arm (difference, 5.2% [95% confidence interval, -.6% to 11%]). There were 5 virological failures in the DTG-I arm and 5 (1 while on PI/r and 4 after switching to DTG) in the DTG-D arm without selection of resistance mutations. There was no significant difference in terms of grade 3 or 4 AEs or treatment-modifying AEs. Total cholesterol and other lipid fractions (except high-density lipoprotein) significantly (P < .001) improved both after immediate and deferred switching to DTG overall and regardless of baseline PI/r strata. Conclusions: Both immediate and deferred switching from a PI/r to a DTG regimen in virologically suppressed HIV-infected patients ≥50 years old or with a Framingham score ≥10% was highly efficacious and well tolerated, and improved the lipid profile.

[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.
