Abstract
Background Rising hepatitis C and B virus (HCV and HBV) rates have been reported in men who have sex with men (MSM) and transgender women (TGW). This study characterizes HCV and HBV infections longitudinally among 2,496 MSM/TGW aged 18-50 years and at risk for HIV acquisition enrolled in an HIV-1 vaccine trial in 18 U.S. cities between 2009-2013. Methods Participants completed behavioral surveys, HIV testing, and blood collection over 24 months. Of the 2,397 participants who consented for future testing, 1,792 (74.8%) had available paired stored blood samples at baseline and a later timepoint (Month 24 [N = 999]; if unavailable, M12 [N = 775] or M15 [N = 18]). Results Among 1,792 participants, 98.1% were MSM, 0.8% were TGW, and the median age was 30 years (IQR 24, 40). Participants reported a median number of 3 male sex partners (IQR 1,5) within the past 3 months. Condomless insertive anal sex was reported by 55.8% and condomless receptive anal sex by 46.7%.1.3% reported injection drug use. During follow-up, 1.4% reported pre-exposure prophylaxis (PrEP) use. At baseline 11/1792 (0.61%) participants had HCV infection (HCV AB positive, RNA detectable), with all having persistent detectable RNA and chronic HCV infection at follow-up. Phylogenetic analysis showed no clusters of HCV infection. 8 participants had HCV AB positive, RNA undetectable at baseline and follow-up, representing past HCV infection with clearance; only 2 acquired HCV, which cleared over 12-24 months. At baseline, 2 participants (2/1792 = 0.11%) had positive HBsAg, indicating chronic HBV infection. Over 12-24 months, 4 (4/1790, 0.22%) developed HBsAg positivity; these participants had HBcAB positivity at baseline, thereby likely representing reactivation. There were no new HBV infections during follow-up. Conclusion Among 1,792 men who have sex with men and transgender women aged 18-50 years and at risk for HIV acquisition enrolled in a U.S. HIV-1 vaccine trial, incident hepatitis C infection rates were extremely low, with no cases of incident hepatitis B infection. These rates of incident HCV infection and HBSAg positivity are lower than previously reported among MSM/TGW.

Abstract
Ongoing sexual transmission presents a significant barrier to viral hepatitis control. Endemic transmission of hepatitis A virus continues through communities of men with male sex partners, despite vaccine availability. Increased incidence of hepatitis B virus from 2014-2018 prompted expanded vaccination guidelines, but uptake and physician awareness remain poor. Hepatitis C virus while strongly associated with injection drug use, is also transmitted by high-risk sexual contact. Despite universal screening recommendations and curative treatment, incidence continues to increase. Even with safe and highly effective vaccinations or treatments, sexual transmission of viral hepatitides must be addressed to achieve disease elimination.

Abstract
BACKGROUND Understanding the risk behaviors associated with sexually-transmitted hepatitis C virus (HCV) infection among men who have sex with men (MSM) may inform the public health policies and interventions aiming to achieve HCV microelimination. METHODS HIV-positive MSM who had one of the following conditions were enrolled to undergo face-to-face questionnaire interviews to collect information on their sexual practices in the past 12 months: (1) elevation of aminotransferases in the past 6 months; (2) acquisition of sexually transmitted infections in the past 6 months; and (3) previous HCV infections. Plasma HCV RNA were tested at enrolment and every 3 months during follow-up. Baseline characteristics and risky behaviors were compared to identify factors associated with HCV viremia between HCV-viremic MSM and HCV-aviremic MSM in multivariate analysis. RESULTS Among 781 MSM with a median age of 36 years, 57 (7.3%) had HCV viremia and 724 (92.7%) no HCV viremia during follow-up. A high proportion (38.9%) of the participants reported having used recreational drugs in the past 12 months, with 34.4% of them having slamming, but only 4.8% reported having shared their injection equipment. In multivariate analysis, use of recreational drugs (adjusted odds ratio [aOR], 2.14; 95% CI, 1.16-3.96), having participated in group sex (aOR, 2.35; 95% CI 1.24-4.40) and having had condomless receptive anal intercourse (aOR, 1.97; 95% CI 1.07-3.62) were significantly associated with HCV viremia. CONCLUSION Among high-risk HIV-positive MSM, use of recreational drugs and risky sexual contacts were associated with HCV viremia, suggesting the mucosal contacts as the major route of HCV transmission.

Abstract
Background The epidemiology of hepatitis C virus (HCV) infection in people living with HIV has been evolving, with increasing evidence of permucosal (sexual) transmission identified predominantly in HIV-positive men who have sex with men (MSM). The aim of this study was to estimate the incidence rate and elucidate epidemiological factors associated with HCV infection among HIV-infected men in Singapore from 2006 to 2018. METHODS A retrospective cohort study was conducted using a clinical database maintained by the Clinical HIV Program at the National Centre for Infectious Diseases, Singapore. Factors associated with incident HCV infections were identified using Cox proportional hazards regression analyses. RESULTS Among 1348 HIV-infected male patients who were HCV seronegative at baseline, 64 (4.7%) subsequently tested positive for HCV, giving an incidence of 0.88 per 100 person-years of follow-up (PYFU) (95% confidence interval (CI) 0.69-1.13). The incidence rate of HCV seroconversion increased from 0.33 (95% CI 0.12-0.71) per 100 PYFU in 2010-2012 to 1.93 (95% CI 1.36-2.67) in 2016-2018. Independent factors associated with incident HCV infection were younger age groups at HIV diagnosis versus ≥45 years, HIV acquisition via MSM or via both sexual contact and intravenous drug use versus heterosexual transmission, HIV diagnosis in later periods versus 2006-2009, and recent syphilis acquisition. CONCLUSIONS An increasing trend of incident HCV infection was seen in HIV-infected men, particularly for MSM. Preventive and behavioural interventions should be targeted at HIV-infected individuals engaged in high-risk sexual behaviour.

Abstract
A systematic review was performed on the evidence of sexual transmission of hepatitis C virus (HCV) in gay and bisexual men (GBM). Studies conducted in industrialised countries and published in English from 2000 to 2015 with data on HCV in GBM were included. Pooled estimates of prevalence and incidence of HCV infection were stratified by study settings and participants' HIV status using random effect models. Case-series reports were summarised descriptively. Of the 38 cross-sectional studies, the pooled HCV prevalence was substantially higher in HIV-positive men (8.3%, 95% CI: 6.7-9.9) than in HIV-negative men (1.5%, 95% CI 0.8-2.1), and higher in those who reported injecting drug use (34.8%, 95% CI 26.9-42.7) than in those who did not (3.5%, 95% CI 2.4-4.5). Of the 16 longitudinal studies, the pooled HCV incidence was markedly higher in clinic-based (7.0 per 1000 person-years, 95% CI 4.6-9.5) than in community-based (1.4 per 1000 person-years, 95% CI 0.7-2.1) studies, and in HIV-positive men (6.4 per 1000 person-years, 95% CI 4.6-8.1) than in HIV-negative men (0.4 per 1000 person-years, 95% CI 0-0.9). Since the early 2000s, 15 case-series reports increasingly pointed to the importance of sexual transmission of HCV in mainly HIV-positive men. Injecting drug use remained the major transmission route of HCV in GBM. Receptive condomless intercourse and concurrent ulcerative sexually transmissible infections are likely drivers that facilitated HCV sexual transmission in HIV-positive men. HCV incidence remains very low in HIV-negative GBM.

Abstract
INTRODUCTION Young adults who inject drugs and live in rural communities are at high risk for hepatitis C virus (HCV) infection. Recent changes in HCV treatment must be communicated within these communities to improve access to care and reduce HCV transmission. METHODS Field workers in the ¡VÁLE! Hepatitis Treatment and Integrated Prevention Services study identified frequently asked questions (FAQs) posed by young-adult participants at high risk for HCV during screening and educational sessions. From 2016 to 2018, 183 young adults (44.3% women; 85.8% Latino/a) younger than 30 years who inject drugs and reside in Rio Arriba or Doña Ana counties in New Mexico were enrolled. The research team compiled deidentified questions during field enrollments. RESULTS FAQs were reviewed and categorized into four major domains, including risk/prevention, screening, treatment, and reinfection. FAQs were addressed by a team of medical and public health professionals, using the most current research and recommendations. CONCLUSIONS These FAQs address important gaps in HCV knowledge among young adults who are at high risk for infection. The FAQs also highlight the importance of risk reduction counseling provided by frontline public health providers as well as access to safe and effective HCV treatments for young adults who inject drugs.

Abstract
OBJECTIVES In persons with hepatitis C virus (HCV) infection, HIV coinfection leads to faster progression to advanced liver disease. The aim of our study was to estimate diagnosed HIV prevalence among people with evidence of current HCV infection (polymerase chain reaction positive) and examine predictors of coinfection. METHODS Adults (≥ 15 years old) with a current HCV infection reported to the Public Health England (PHE) sentinel surveillance of blood-borne viruses were linked to the PHE national HIV database using a deterministic methodology. Descriptive and multivariate analyses were conducted. RESULTS Between 2008 and 2014, 5.0% (999/20 088) of adults with a current HCV infection were diagnosed with HIV coinfection. The majority acquired HIV through sex between men (441; 64.9%), followed by injecting drug use (153; 22.5%) and heterosexual contact (84; 12.4%). Of persons who were coinfected, 65.5% had been diagnosed with HIV infection > 6 months before their HCV diagnosis, 41.4% of whom had a negative anti-HCV test between their HIV and HCV diagnoses. In a multivariable model among persons with current HCV infection, an HIV diagnosis was more likely among men [adjusted odds ratio (aOR) 3.29; 95% confidence interval (CI) 2.60-4.16] and persons of black ethnicity (aOR 3.19; 95% CI 1.36-7.46), and less likely among older adults (aOR 0.85 per 10-year increase; 95% CI 0.79-0.92) and persons of Asian ethnicity (aOR 0.59; 95% CI 0.41-0.86). CONCLUSIONS Our results indicate that the majority of diagnosed HIV and current HCV coinfections are among men who have sex with men. Safer sex campaigns should include awareness of transmission of HCV among MSM living with HIV.

Abstract
The management of acute HCV infection has not been standardized following the availability of direct-acting antiviral agents (DAAs) for chronic HCV infection, and substantial uncertainty exists regarding the optimal treatment regimen and duration. Despite the lack of direct evidence, the 2016 American Association for the Study of Liver Diseases (AASLD)-Infectious Diseases Society of America (IDSA) guidelines supported "the same regimens for acute HCV as recommended for chronic HCV infection … owing to high efficacy and safety", whereas the 2016 European Association for the Study of the Liver (EASL) guidelines recommended sofosbuvir-ledipasvir, sofosbuvir-velpatasvir or sofosbuvir plus daclatasvir for 8 weeks in acute HCV infection, with a longer duration of 12 weeks recommended for those infected with HIV and/or baseline HCV RNA levels >1,000,000 IU/ml. This Review outlines the epidemiology, natural history and diagnosis of acute HCV infection and provides contemporary information on DAAs for acute and recent HCV infection. The Review also discusses the 2016 AASLD-IDSA and EASL recommendations for acute HCV infection management in light of available evidence and highlights key differences in study populations and design that influence interpretation. We focus on populations at high risk of HCV transmission and acquisition, including people who inject drugs and HIV-positive men who have sex with men, and highlight the potential effects of diagnosis and treatment of acute HCV infection in contributing to HCV elimination.

Abstract
The aims of this study were to describe the evolution of acute hepatitis C virus (HCV) infections since 2004 and to determine its associated factors. Acute HCV infections diagnosed in Barcelona from 2004 to 2015 were included. Incidence ratios (IR) were then estimated for sex and age groups. Cases were grouped between 2004-2005, 2006-2011 and 2012-2015, and their incidence rate ratios (IRR) were calculated. In addition, risk factors for acute HCV infection were identified using multinomial logistic regression for complete, available and multiple imputed data. 204 new HCV cases were identified. Two peaks of higher IR of acute HCV infection in 2005 and 2013 were observed. Men and those aged 35-54 had higher IR. IRR for men was 2.9 times greater than in women (95% confidence intervals (CI): 1.8 ‒ 4.7). Factors related to the period 2012-2015 (versus 2006-2011) were: a) sexual risk factor for transmission versus nosocomial (relative-risk ratio (RRR): 13.0; 95% CI: 2.3 ‒ 72.1), b) higher educated versus lower (RRR: 5.4; 95% CI: 1.6 ‒ 18.7), and c) HIV co-infected versus not HIV-infected (RRR: 53.1; 95% CI: 5.7 ‒ 492.6). This is one of the few studies showing IR and RRRs of acute HCV infections and the first focused on a large city in Spain. Sexual risk for transmission between men, higher educational level and HIV co-infection are important factors for understanding current HCV epidemic. There has been a partial shift in the pattern of the risk factor for transmission from nosocomial to sexual.

Evaluation of hepatitis C testing in men who have sex with men, and associated risk behaviours, in Manchester, UK. Sex Transm Infect 2017; 93:404-409. [PMID: 28130506 DOI: 10.1136/sextrans-2016-052876] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2016] [Revised: 01/03/2017] [Accepted: 01/08/2017] [Indexed: 01/04/2023] Open
Abstract
OBJECTIVE To determine the prevalence of newly diagnosed hepatitis C virus (HCV) and associated risk behaviours among men who have sex with men (MSM) in Manchester. METHOD A survey among MSM attending four genitourinary medicine clinics in Manchester was carried out over 9 months in 2013. Participants were asked about recent sexual behaviour, recreational drug use and HIV status. All men were offered an HCV test. RESULTS Overall, 2030 MSM completed a questionnaire and accepted an HCV test. Of whom, 0.9% (18) were newly diagnosed with HCV, including 1.8% (13/735) of HIV-positive MSM, 0.7% (3/440) of MSM of unknown HIV status and 0.2% (2/855) of HIV-negative MSM. HCV positivity was significantly associated with HIV status (p<0.001). When compared with HIV-negative MSM, HIV-positive MSM had higher rates of sharing snorting drug equipment, injecting drugs/'slamming' and using recreational drugs (all p<0.05) but lower rates of five or more sexual partners and insertive unprotected anal intercourse (p<0.05). MSM newly diagnosed with HCV had significantly higher prevalence of unprotected sex, sex with someone HCV positive, fisting, group sex, ever injecting drugs/'slamming' and recreational drug use (p<0.002). CONCLUSIONS In this survey, HIV-positive MSM had significantly different drug use behaviour which may explain the higher HCV burden. However, HCV was also associated with HIV-negative MSM engaging in high-risk sexual practices. All MSM attending sexual health clinics must have a risk assessment and HCV screening should be offered based on the risk. Further studies are warranted to explore the interplay between HCV and HIV risk associated with drug use versus sexual practices.

Abstract
Injecting risk behaviours among people who inject drugs (PWID) and high-risk sexual practices among men who have sex with men (MSM) are important routes of hepatitis C virus (HCV) transmission. Current direct-acting antiviral treatment offers unique opportunities for reductions in HCV-related liver disease burden and epidemic control in high-risk groups, but these prospects could be counteracted by HCV reinfection due to on-going risk behaviours after successful treatment. Based on existing data from small and heterogeneous studies of interferon-based treatment, the incidence of reinfection after sustained virological response range from 2-6/100 person years among PWID to 10-15/100 person years among human immunodeficiency virus-infected MSM. These differences mainly reflect heterogeneity in study populations with regards to risk behaviours, but also reflect variations in study designs and applied virological methods. Increasing levels of reinfection are to be expected as we enter the interferon-free treatment era. Individual- and population-level efforts to address and prevent reinfection should therefore be undertaken when providing HCV care for people with on-going risk behaviour. Constructive strategies include acknowledgement, education and counselling, harm reduction optimization, scaled-up treatment including treatment of injecting networks, post-treatment screening, and rapid retreatment of reinfections.

Abstract
PURPOSE OF REVIEW Modern interferon (IFN)-free, and potentially also ribavirin-free, combinations consisting of two or three direct-acting antivirals (DAAs) are highly efficacious in treating chronic hepatitis C virus (HCV) infection with treatment durations being much shorter and with much more favorable toxicity profiles. With the acute HCV (AHC) epidemic among men who have sex with men (MSM) still ongoing, the question remains should we be using DAAs in the acute phase of the infection? RECENT FINDINGS To date, none of the currently available DAAs has been licensed for use in the setting of AHC infection. Thus, the current gold standard of treatment still is a combination of pegylated interferon (pegIFN) and weight-adapted ribavirin (RBV). However, with less patients being treated in the acute phase, the current epidemic of AHC in HIV-positive MSM will continue. SUMMARY A decision to treat AHC with pegIFN and RBV can currently only be made on an individual basis in an open discussion between patient and physician which will need to weigh up the risk and benefits of a rather toxic and lengthy treatment now versus the likely available options in the chronic phase. Therefore, studies with IFN-free DAA combinations remain of great urgency to further evaluate the role of DAAs in the treatment of AHC.

Abstract
HIV-1 infected patients who acquire HCV infection have higher rates of chronicity and liver disease progression than patients with HCV mono-infection. Understanding early events in this pathogenic process is important. We applied single genome sequencing of the E1 to NS3 regions and viral pseudotype neutralization assays to explore the consequences of viral quasispecies evolution from pre-seroconversion to chronicity in four co-infected individuals (mean follow up 566 days). We observed that one to three founder viruses were transmitted. Relatively low viral sequence diversity, possibly related to an impaired immune response, due to HIV infection was observed in three patients. However, the fourth patient, after an early purifying selection displayed increasing E2 sequence evolution, possibly related to being on suppressive antiretroviral therapy. Viral pseudotypes generated from HCV variants showed relative resistance to neutralization by autologous plasma but not to plasma collected from later time points, confirming ongoing virus escape from antibody neutralization.

Abstract
The aim of this study was to characterize the current molecular epidemiology of hepatitis C virus (HCV) infection and evaluate the evolutionary patterns of HCV subtypes in Beijing, China, among different subpopulations.The whole blood samples and behavioral data were collected from a total of 10,354 subjects, including drug users (DUs), men who have sex with men (MSM), and the general population, in Beijing from 2010 to 2011. Samples were tested for HCV infection using both enzyme-linked immunosorbent assay (ELISA) and real-time PCR. All viremic subjects were then sequenced by nested PCR over core/E1 and NS5B regions. Phylogenetic and phylogeographic analysis was performed by BEAST software.In total, 217 subjects (2.1%) were tested positive for HCV by antibody or vRNA-based testing. HCV prevalence rates for DUs, MSM, and the general population were 26.2%, 0.54%, and 0.37%, respectively. The 156 HCV RNA-positive samples were sequenced. Nine HCV genotypes, including 1a, 1b, 2a, 3a, 3b, 6a, 6n, 6u and 6v, were detected. The most prevalent subtypes were 3b (36.09%), 1b (32.54%), and 3a (16.57%). Bayesian evolutionary analysis estimated that the time of introduction of subtype 1b into Beijing was 2004 (95% CI: 1997.7, 2007.7), with subtypes 3a and 3b being introduced later in 2006. Evolutionary analyses further suggested that subtype 1b from Beijing and Shanghai were closely related, whereas subtype 3a sequences were more similar with sequences from Yunnan, Guangzhou, Hong Kong, and Jiangsu. Subtype 3b sequences were closely related to those from Yunnan, Guangdong, and Hong Kong.Thus, the current HCV epidemic in Beijing is complex, heavily affecting DUs, and involving multiple genotypes that likely spread from different regions in China with its large migrant population.

Abstract
HCV and liver disease have emerged as major causes of morbidity and mortality in HIV-positive patients. Treating HCV in patients with HIV has been challenging up until a few years ago due to poorer outcomes with interferon-based therapies in this population. The direct-acting antiviral (DAA) agents offer a new era in the treatment of HCV for all patients regardless of HIV status. This article reviews multiple aspects of the care of the coinfected patient with a focus on the modern DAA agents. HCV clinical treatment trials involving HIV-positive patients and antiretroviral therapy/DAA drug–drug interactions are reviewed in detail.

Abstract
BACKGROUND & AIMS In the last decade, several outbreaks of sexually acquired acute hepatitis C (HCV) infection have been described in HIV-positive men who have sex with men (MSM). The aims of this study were to determine whether there has been an increase in the number of acute HCV infections in different parts of Europe. METHODS HCV seroconversion was defined as an HCV-antibody test change from negative to positive within the observation period in EuroSIDA. Binomial regression was performed to determine factors associated with being tested for HCV and HCV seroconversion. RESULTS A total of 223 HCV seroconversions were observed from 16,188 tests [1.38% (95%CI 1.20-1.56)] among 5736 patients between 2002 and 2013. Overall the odds of acquiring HCV infection increased by 4% per year (OR 1.04 [95%CI 0.99-1.09]; P = 0.10). Overall 63.2% (141/223) of all seroconversions were seen among MSM. Similar patterns were observed across all European regions (P = 0.69, test for interaction) and HIV transmission risks groups (P = 0.69, test for interaction). In multivariate analysis, North, South and East Europe had higher odds of HCV seroconversion compared with Western Europe [OR 1.90 (1.28-2.81), 1.55 (0.99-2.45) and 1.86 (1.21-2.84); P = 0.0014, P = 0.058 and P = 0.0044 respectively]. CONCLUSIONS Within EuroSIDA a significant increase in HCV seroconversions can be observed after accounting for increased levels of testing for HCV in recent years. This highlights the need for increased HCV prevention efforts among HIV-positive persons in Europe.

Abstract
OBJECTIVES The incidence of hepatitis C virus (HCV) infection among HIV-negative men who have sex with men (MSM) is rarely investigated in the Asia-Pacific region. We aimed to estimate the incidence rate of and factors associated with recent HCV infection among the clients seeking voluntary counselling and testing (VCT) services for HIV in Taiwan. METHODS During 2006-2013, 12 143 clients sought VCT services for HIV. Clients with subsequent follow-up tests at an interval of 6 months or longer were included to estimate the incidence rate of HCV seroconversion. Phylogenetic analysis of HCV sequences from VCT clients and HIV-positive patients was performed. RESULTS The overall HCV seroprevalence at baseline was 0.3%. Of 2150 clients testing negative for anti-HCV antibody at baseline with a total of 5074.99 person-years of follow-up (PYFU), 17 (0.8%) developed HCV seroconversion, leading to an overall incidence rate of 3.35 per 1000 PYFU (95% CI 1.76 to 4.94), which increased from 2.28 (95% CI 0.05 to 4.51) in 2006-2009, to 3.33 (95% CI 0.86 to 5.80) in 2010 to 2011 and 4.94 per 1000 PYFU (95% CI 0.99 to 8.99) in 2012-2013; the incidence of early syphilis increased from 11.91 to 13.28 and 31.78 per 1000 PYFU in the three corresponding periods. In multivariate analysis, having HIV-positive partners (adjusted HR (AHR) =3.756; 95%CI 1.180 to 11.955) and developing a rapid plasma reagin titre of 4 or greater (AHR=9.978; 95% CI 1.550 to 64.233) were significantly associated with HCV seroconversion. CONCLUSIONS An increasing trend of recent HCV infection occurs among individuals seeking VCT services in Taiwan. Having HIV-positive partners and having syphilis are independently associated with recent HCV seroconversion.

Abstract
Background Hepatitis C virus (HCV) infection has been increasingly recognized among HIV-infected men who have sex with men (MSM) worldwide. We investigated the trend of and factors associated with acute hepatitis C (AHC) among HIV-infected individuals in Taiwan. Methods The National Disease Surveillance System collects characteristics of AHC, HIV, syphilis, and gonorrhea cases through mandatory reports and patient interviews. Reported AHC patients in 2014 were interviewed additionally on sexual and parenteral exposures. Information on HCV genotypes were collected from the largest medical center serving HIV-infected Taiwanese. We defined an HIV/AHC case as a documented negative HCV antibody test result followed within 12 months by a positive test in a previously reported HIV-infected individual. Each case was matched to two HIV-infected, non-AHC controls for age, age of HIV diagnosis, sex, transmission route, HIV diagnosis date, and county/city. Conditional logistic regression was used to identify associated characteristics. Results During 2001–2014, 93 of 6,624 AHC reports were HIV/AHC cases; the annual case count increased from one in 2009 to 34 in 2014. All were males (81 [87%] MSM) aged 21–49 years with AHC diagnosed 2–5,923 days after HIV diagnoses. Sixty-eight (73%) lived in the Taipei metropolitan area. Detected HCV genotypes were 2a (n = 6), 1b (n = 5), 1b + 2a (n = 1) and 2b (n = 1). Among 28 HIV/AHC patients interviewed in 2014, 13 (46%) reported engaging in unprotected sex ≤3 months before AHC diagnosis. Seventy-nine HIV/AHC cases were matched to 158 controls. HIV/AHC was associated with recent syphilis (adjusted odds ratio [aOR], 10.9; 95% confidence interval [CI], 4.2–28.6) and last syphilis >6 months (aOR, 2.9; 95% CI, 1.2–6.9). Conclusions HIV/AHC cases continued to increase particularly among sexually active HIV-infected MSM with a syphilis diagnosis in northern Taiwan. We recommend surveillance of associated behavioral and virologic characteristics and HCV counseling and testing for HIV-infected men in Taiwan.

Abstract
Both human immunodeficiency virus (HIV) and viral hepatitis constitute major disease burden globally. As with other parts of the world, the HIV epidemic in Asia impacts mainly on men who have sex with men, one of the at-risk populations for sexually transmitted viral hepatitis. With the increasing availability of effective antiretroviral therapy, HIV-related mortality of people living with HIV has markedly reduced. Liver disease has become an important cause of mortality and morbidity in the HIV-infected population. With the improvement of socioeconomic conditions and availability of healthcare in Asian countries in recent years, the epidemiology of sexually transmitted viral hepatitis among HIV-positive men who have sex with men has also evolved. This review updates the epidemiology of different types of sexually transmitted viral hepatitis in this defined population in Asia.

Abstract
Background. Since 2000, incidence of sexually acquired hepatitis C virus (HCV)-infection has increased among human immunodeficiency virus (HIV)-infected men who have sex with men (MSM). To date, few case-control and cohort studies evaluating HCV transmission risk factors were conducted in this population, and most of these studies were initially designed to study HIV-related risk behavior and characteristics. Methods. From 2009 onwards, HIV-infected MSM with acute HCV infection and controls (HIV-monoinfected MSM) were prospectively included in the MOSAIC (MSM Observational Study of Acute Infection with hepatitis C) study at 5 large HIV outpatient clinics in the Netherlands. Written questionnaires were administered, covering sociodemographics, bloodborne risk factors for HCV infection, sexual behavior, and drug use. Clinical data were acquired through linkage with databases from the Dutch HIV Monitoring Foundation. For this study, determinants of HCV acquisition collected at the inclusion visit were analyzed using logistic regression. Results. Two hundred thirteen HIV-infected MSM (82 MSM with acute HCV infection and 131 MSM without) were included with a median age of 45.7 years (interquartile range [IQR], 41.0–52.2). Receptive unprotected anal intercourse (adjusted odds ratio [aOR], 5.01; 95% confidence interval [CI], 1.63–15.4), sharing sex toys (aOR, 3.62; 95% CI, 1.04–12.5), unprotected fisting (aOR, 2.57; 95% CI, 1.02–6.44), injecting drugs (aOR, 15.62; 95% CI, 1.27–192.6), sharing straws when snorting drugs (aOR, 3.40; 95% CI, 1.39–8.32), lower CD4 cell count (aOR, 1.75 per cubic root; 95% CI, 1.19–2.58), and recent diagnosis of ulcerative sexually transmitted infection (aOR, 4.82; 95% CI, 1.60–14.53) had significant effects on HCV acquisition. Conclusions. In this study, both sexual behavior and biological factors appear to independently increase the risk of HCV acquisition among HIV-infected MSM.

Abstract
While hepatitis C virus (HCV) infection seems to be expanding among HIV-infected men who have sex with men (MSM), the rate of coinfection in intravenous drug users (IDU) is assumed to remain constant. We evaluated the serial prevalence of HIV/HCV coinfection across all risk groups for HIV infection in Spain. We used data from 7045 subjects included in the multicentre, prospective Spanish Cohort of Adult HIV-infected Patients (CoRIS) between 2004 and 2011. We analysed risk factors for HIV/HCV coinfection by logistic regression analyses. The prevalence of HIV/HCV coinfection decreased from 25.3% (95% CI, 23.1-27.5) in 2004-2005 to 8.2% (95% CI, 6.9-9.5) in 2010-2011. This trend was consistently observed from 2004 to 2011 among all risk groups: IDU, 92.4% to 81.4%; MSM, 4.7% to 2.6%; heterosexual men, 13.0-8.9%; and heterosexual women, 14.5-4.0% (all P < 0.05). Strongest risk factors for HIV/HCV coinfection were IDU (OR, 54.9; 95% CI, 39.4-76.4), birth decade 1961-1970 (OR, 2.1; 95% CI, 1.1-3.7) and low educational level (OR, 2.4; 95% CI, 1.6-3.5). Hence, the prevalence of HIV/HCV coinfection decreased in Spain between 2004 and 2011. This decline was observed across all risk groups and is likely to be explained by a declining burden of HCV in the general population.

Abstract
Background. The hepatitis C virus (HCV) epidemic is evolving rapidly in patients infected with human immunodeficiency virus (HIV). We aimed to describe changes in treatment uptake and outcomes of incident HCV infections before and after 2006, the time-point at which major changes in HCV epidemic became apparent. Methods. We included all adults with an incident HCV infection before June 2012 in the Swiss HIV Cohort Study, a prospective nationwide representative cohort of individuals infected with HIV. We assessed the following outcomes by time period: the proportion of patients starting an HCV therapy, the proportion of treated patients achieving a sustained virological response (SVR), and the proportion of patients with persistent HCV infection during follow-up. Results. Of 193 patients with an HCV seroconversion, 106 were diagnosed before and 87 after January 2006. The proportion of men who have sex with men increased from 24% before to 85% after 2006 (P < .001). Hepatitis C virus treatment uptake increased from 33% before 2006 to 77% after 2006 (P < .001). Treatment was started during early infection in 22% of patients before and 91% after 2006 (P < .001). An SVR was achieved in 78% and 29% (P = .01) of patients treated during early and chronic HCV infection. The probability of having a detectable viral load 5 years after diagnosis was 0.67 (95% confidence interval [CI], 0.58-0.77) in the group diagnosed before 2006 and 0.24 (95% CI, 0.16-0.35) in the other group (P < .001). Conclusions. In recent years, increased uptake and earlier initiation of HCV therapy among patients with incident infections significantly reduced the proportion of patients with replicating HCV.

Abstract
With the advent of direct-acting antivirals (DAAs), the treatment of chronic hepatitis C virus (HCV) infection (CHC) has been revolutionized. Modern interferon- and potentially also ribavirin-free combinations consisting of 2 or 3 direct-acting antivirals (DAA) promise sustained virological response rates (SVR) of above 90%. This coincides with much shorter treatment durations and a much more favorable toxicity profile. Some DAAs even work across all HCV genotypes (pangenotypic) [BMJ, 349, 2014, g3308]. And lastly, HCV treatment in HIV-coinfected patients will no longer differ from HCV-monoinfected patients as response rates under DAA in the setting of HCV-HIV coinfection have been as good as in HCV-monoinfected patients [J Hepatol, 61, 2014, 373]. Only drug-drug interactions with the new DAAs and concomitant antiretroviral therapy have to be accounted for due to shared metabolization pathways via the cytochrome p450 system.

Abstract
Objectives We aim to describe rates and risk factors of Hepatitis C Virus (HCV) diagnoses, follow-up HCV testing and HCV seroconversion from 2004–2011 in a cohort of HIV-positive persons in Spain. Methods CoRIS is a multicentre, open and prospective cohort recruiting adult HIV-positive patients naïve to antiretroviral therapy. We analysed patients with at least one negative and one follow-up HCV serology. Incidence Rates (IR) were calculated and multivariate Poisson regression was used to estimate adjusted Rates Ratios (aIRR). Results Of 2112 subjects, 53 HCV diagnoses were observed, IR = 0.93/100py (95%CI: 0.7–1.2). IR increased from 0.88 in 2004–05 to 1.36 in 2010–11 (aIRR = 1.55; 95%CI: 0.37–6.55). In men who have sex with men (MSM) from 0.76 to 1.10 (aIRR = 1.45; 95%CI: 0.31–6.82); in heterosexual (HTX) subjects from 1.19 to 1.28 (aIRR = 1.08; 95%CI: 0.11–10.24). HCV seroconversion rates decreased from 1.77 to 0.65 (aIRR = 0.37; 95%CI: 0.12–1.11); in MSM from 1.06 to 0.49 (aIRR = 0.46; 95%CI: 0.09–2.31); in HTX from 2.55 to 0.59 (aIRR = 0.23; 95%CI: 0.06–0.98). HCV infection risk was higher for injecting drug users (IDU) compared to HTX (aIRR = 9.63;95%CI: 2.9–32.2); among MSM, for subjects aged 40–50 compared to 30 or less (IRR = 3.21; 95%CI: 1.7–6.2); and among HTX, for female sex (aIRR = 2.35; 95%CI: 1.03–5.34) and <200 CD4-count (aIRR = 2.39; 95%CI: 0.83–6.89). Conclusion We report increases in HCV diagnoses rates which seem secondary to intensification of HCV follow-up testing but not to rises in HCV infection rates. HCV IR is higher in IDU. In MSM, HCV IR increases with age. Among HTX, HCV IR is higher in women and in subjects with impaired immunological situation.

Abstract
BACKGROUND Human immunodeficiency virus (HIV)-infected, hepatitis C virus (HCV)-uninfected patients are at risk for incident HCV infection, but little is known about screening practices for incident HCV among HIV-infected individuals in HIV primary care clinics. METHODS We used data from the Center for AIDS Research Network of Integrated Clinical Systems (CNICS) to investigate historical trends in screening for incident HCV infection among HIV-infected patients who were HCV-uninfected at enrollment in care. We used descriptive measures and Poisson regression to identify factors associated with screening for HCV infection (using HCV antibody or RNA), performed temporal analyses to assess changes in screening over time, and investigated the frequency with which elevated alanine aminotransferase (ALT) levels were followed by diagnostic HCV testing. RESULTS Among 17 090 patients registered at CNICS sites between 2000 and 2011, 14 534 (85%) received HCV antibody screening within 3 months of enrolling in care, and 9077 met all of the inclusion criteria. Only 55.6% ever received additional HCV screening. HCV screening increased over time, but not uniformly at all sites. Only 26.7% of first-time ALT elevations to >100 IU/L were followed up within 12 months by HCV antibody or RNA testing. CONCLUSIONS Although most HIV-infected patients were screened for prevalent HCV infection at enrollment in care, only half who were HCV uninfected were screened again. Screening varied between sites, even when controlling for demographics and risk behaviors. Patients with new ALT elevations to >100 IU/L were seldom assessed for incident HCV infection. Guidelines are needed to help HIV providers know whom to screen, how frequently to screen, and which screening test to use.

Abstract
The ongoing epidemic of acute hepatitis C (AHC) infection among MSM highlights the need to identify factors allowing for optimal treatment outcome in HIV co-infected individuals. Cohort study of 105 HIV-infected patients with AHC infection from five centres in two European countries was carried out. Choice of treatment with pegIFN-alfa alone (group 1; n = 36) or pegIFN-alfa and ribavirin (RBV) (group 2; n = 69) was at the discretion of the investigator. Outcome was evaluated as RVR and SVR. Fisher's exact and Mann Whitney U tests were used for statistical analysis. All patients were male, median age was 39 years, main route of transmission MSM (91%). In 69% of patients, clinical signs of acute hepatic infection were missing, dominant HCV genotypes were 1 (64%) and 4 (16%) and mean baseline HCV-RNA was 3.559.085 IU/mL. 60% received HAART and CD4 cell count was 469/mm(3) . Overall SVR rate was 64.8% (68/105). SVR was reached in 69% of treated patients in group 1 and in 63% of treated patients in group 2 (P = 0.67) while RVR was seen in 61% and 49%, respectively (P = 0.35). Interestingly, by univariate analysis, SVR rates in group 1 were significantly higher in patients initiating therapy within 4 weeks of AHC diagnosis compared to patients initiating therapy within 5-36 weeks after diagnosis (P = 0.03). PegIFN-alfa alone or in combination with ribavirin results in similar response rates in HIV-infected patients with AHC. In particular, when treatment is initiated within 4 weeks of diagnosis, pegIFN mono-therapy might be sufficient to allow for an optimal treatment response.

Abstract
OBJECTIVE Project Renaissance is a randomized controlled trial of an HIV/hepatitis C virus (HCV)/sexually transmitted infection (STI) prevention intervention conducted in Almaty, Kazakhstan. We hypothesized that couples assigned to the intervention of interest will have lower incidence of HIV, HCV, STIs, rates of unprotected sex, and unsafe injection over the 12-month follow-up period compared with those assigned to an attention control arm. DESIGN A total of 300 couples (600 participants) where one or both partners reported injecting drugs in the past 90 days were randomized to 1 of 2 arms: (1) a 5-session HIV/HCV/STI prevention intervention (risk reduction: RR) or (2) a 5-session Wellness Promotion (WP) intervention. RESULTS Over the 12-month follow-up period, assignment to RR compared with WP significantly lowered the incidence of HCV infection by 69% [incidence rate ratios (IRR) = 0.31, 95% (CI) confidence interval: 0.10 to 0.90, P = 0.031]. Although differences were not statistically significant, RR participants had a lower incidence of HIV infection by 51% (IRR = 0.49, 95% CI: 0.16 to 1.48, P = 0.204) and any STI by 37% (IRR = 0.63, 95% CI: 0.21 to 1.93, P = 0.418) than WP participants. RR participants reported significantly fewer numbers of unprotected vaginal sex acts with their study partners (IRR = 0.58, 95% CI: 0.36 to 0.93, P = 0.024) and more consistent condom use (odds ratios = 2.30, 95% CI: 1.33 to 4.00, P = 0.003) over the entire follow-up period compared with WP participants. CONCLUSIONS Project Renaissance demonstrated a significant effect for biological and behavioral endpoints. Findings draw attention to an HIV/HCV/STI prevention intervention strategy that can be scaled up for drug-involved couples in harm reduction programs, drug treatment, and criminal justice settings.

BACKGROUND While the numbers of hepatitis-C-virus (HCV) infections among men who have sex with men (MSM) who are co-infected with the human immunodeficiency virus (HIV) are on the rise, with vast evidence for sexual transmission of HCV in this population, concerns have also been raised regarding sexual HCV-transmission among MSM without HIV infection. Therefore, the aim of this study was to estimate the prevalence of hepatitis C among MSM without HIV diagnosis in Zurich (Switzerland). METHODS Participants were recruited from a gay health centre and various locations such as dark rooms, saunas and cruising areas in Zurich. Participants self-completed a questionnaire assessing known and suspected risk factors for HCV-infection, and provided a blood sample for detection of past (antibodies) and present (core antigen, RNA) infections with HCV. RESULTS In total, 840 MSM aged 17-79 (median: 33 years) underwent HCV-testing and completed the questionnaire, among whom 19 reported living with HIV. Overall, seven tested positive for HCV-antibodies, and two were also positive for HCV core antigen and HCV-RNA-these two were immigrants, one from a country where HCV is endemic. None of the seven were aware of their infection. The seroprevalence of hepatitis C among the 821 non-HIV-diagnosed MSM was 0.37% (95%-CI: 0.12-1.69%), and one man harboured replicating virus (0.12%; 0.02-0.69%), resulting in a number needed to test of 821 to detect one active infection. Significant univariable associations of lifetime HCV-infection were found with known HIV-diagnosis (OR=72.7), being tattooed (OR=10.4), non-injection use of cocaine/amphetamines (OR=8.8), and non-Swiss origin (OR=8.5). For MSM without HIV-diagnosis, the only variable marginally associated with positive HCV-serostatus was being tattooed (OR=8.3). No significant associations were observed with reported injection drug use, unprotected anal intercourse, sexual practices that may lead to mucosal trauma, or proxy measures for group sex and lesion-prone STIs. CONCLUSIONS Our findings suggest that in Switzerland, hepatitis C among MSM without diagnosed HIV is not more prevalent than in the general population. We found no evidence of elevated rates of sexual transmission of HCV among MSM without HIV-infection. Therefore, we currently see no reason for promoting HCV-testing among all MSM in Switzerland.

Abstract
Identification and vaccination of adults at risk for hepatitis B virus acquisition through sexual contact is a key strategy to reduce new hepatitis B virus infections among at-risk adults. Hepatitis C has emerged as a sexually transmitted infection among men with male sex partners (MSM). Several biological and behavioral factors have been linked to hepatitis C virus transmission among MSM, including human immunodeficiency virus coinfection; participation in sexual practices that result in mucosal damage or result in exposure to blood; presence of sexually transmitted diseases (STIs), particularly ulcerative STIs; multiple/casual sex partners; and unprotected anal intercourse.

Abstract
Objectives For the last 10 years there has been an epidemic of hepatitis C virus (HCV) infection in men who have sex with men (MSM) in Europe, North America and Australia. The majority of those infected are also HIV-positive and it is unclear to what extent HIV-negative MSM are also at increased risk of infection with HCV. This study provides the first examination of the association between HIV and hepatitis C serostatus in a sample of MSM recruited in community settings. Methods A total of 1121 participants completed a short questionnaire in 2008/2009 giving demographic and behavioural data, and donated a sample of oral fluid that was subsequently tested for antibodies to selected pathogens (HIV, syphilis and HCV). Results The seroprevalence of hepatitis C antibody was 2.1% [95% confidence interval (CI) 1.4–3.2%]. It was more common in those with HIV infection [7.7% (95% CI 4.2–12.9%) vs. 1.2% (95% CI 0.6–2.1%) in those without HIV infection; P < 0.001], those with a history of syphilis [12.2% (95% CI 4.6–24.8%) vs. 1.7% (95% CI 1.0–2.6%) in those without such a history; P < 0.001] and those who reported casual unprotected anal intercourse in the previous year [4.1% (95% CI 2.0–7.4%) vs. 1.2% (95% CI 0.5–2.2%) in those who did not report such intercourse; P = 0.01]. There was no relationship between hepatitis C antibody (anti-HCV) status and other demographic variables (age, ethnicity, employment status or education). Conclusions The seroprevalence of anti-HCV in HIV-negative MSM (1.2%) was higher, but not significantly higher, than that in the general population (0.67%). The prevalence was significantly higher in those infected with HIV or with previous syphilis infection and in those reporting unprotected anal intercourse. Our findings support current British Association for Sexual Health and HIV guidelines recommending the provision of selective HCV testing in MSM according to individual risk profile.

Abstract
BACKGROUND Chronic hepatitis C virus (HCV) infection has become a leading cause of non-acquired immunodeficiency syndrome (AIDS)-related morbidity and mortality for human immunodeficiency virus (HIV)-infected persons in the highly active antiretroviral therapy (HAART) era. Despite injection drug use (IDU) remaining the main route of HCV infection, recent reports indicate outbreaks of acute HCV infection among HIV-infected men who have sex with men (MSM) and sexually transmitted infections in the absence of IDU. METHODS We conducted a retrospective observational study of behavioural and demographic factors of patients with and without incident HCV infection among HIV-infected individuals followed at the AIDS Clinic of the Infectious Disease Department of the University of Ancona from 1989 to 2011. RESULTS Overall, 440 patients were considered; a total of 145 patients had initial positive HCV antibody test results (HCV+); a total of 295 patients had initial negative HCV antibody test results (HCV-). In the latter population, 14 seroconverted to HCV antibody (neoHCV), with an overall incidence of 0.59 per 100 person-years. While IDU was the principal risk factor of HCV+, the main route of transmission of incident HCV infection was sexual transmission. The HCV- group was significantly older than the other two groups and showed a significantly lower CD4 count at HIV diagnosis than neoHCV. Being Italian and having a low level of education were significantly more represented in HCV+. Younger age at HIV infection, IDU and additional risk factors other than sexual transmission significantly affected the probability of being HCV+. The cumulative probability of developing HCV infection in the HCV- group was calculated to be 6% at 15 years. CONCLUSIONS The epidemiology of the newly acquired HCV in HIV+ persons is changing. Therefore, a frequent and constant counselling about HCV infection is desirable and a periodical screening test is mandatory.

Abstract
PURPOSE OF REVIEW Increasing evidence has emerged for permucosal transmission of hepatitis C amongst HIV-infected MSM. RECENT FINDINGS A rising incidence of acute hepatitis C virus (HCV) in HIV-infected MSM has been observed since 2000 in Europe, Australia, USA and Asia. Transmission appears to occur through the permucosal rather than the more usual parenteral route. Although often multifactorial, permucosal risk factors can be classified as behavioural (sexual practices and mucosally administered drugs) and biological (HIV and sexually transmitted infections). This review will describe the epidemiology of HCV infection in this cohort. Current and future treatment strategies will also be outlined in the context of novel, orally bioavailable, directly acting antiviral therapies. SUMMARY An improved understanding of HCV epidemiology will allow implementation of more effective public health interventions to limit onward transmission of HCV.

Abstract
Acute hepatitis C infection in the context of HIV is an emerging problem in men who have sex with men (MSM). We conducted a retrospective cohort study of MSM diagnosed with and treated for acute hepatitis C infection over 10 years. Genotype 1 was the commonest type representing 69% of cases; the spontaneous clearance rate was 20%. The overall sustained virological response (SVR) rate on an intention-to-treat basis was 83%; SVR and was 92% for those completing 48 weeks of treatment. The presence of detectable RNA at week 12 had a 100% negative predictive value for SVR. This is the largest single cohort treated with 48 weeks of interferon and ribavirin and the treatment SVR is one of the highest reported. We propose that a 48-week treatment regimen may be superior to shorter (24-week) regimens though we acknowledge the need for a randomized controlled trial.

Abstract
With the decrease in transmission via transfusions and injection drug use, acute symptomatic hepatitis C is infrequently seen in developed countries. We report a case of a human immunodeficiency virus (HIV)-infected adult who presented with abdominal pain. His alanine aminotransferase was greater than sixty times the upper limit of normal without any evidence on examination of fulminant hepatic failure. His workup revealed an elevated hepatitis C viral level with a negative hepatitis C antibody. He was discharged once his liver function tests improved. As an outpatient, he had a recurrent bout of symptoms with an elevation of his alanine aminotransferase and hepatitis C viral levels that promoted anti-hepatitis C virus treatment. This case illustrates the importance of considering acute hepatitis C as a cause of acute hepatitis in HIV-infected men who have sex with men. While patients with acute symptomatic hepatitis C generally have a higher rate of spontaneous viral clearance compared to those with an insidious acute infection, most still progress to chronic hepatitis C infection, and patients with HIV coinfection carry a higher risk of progression to chronic disease.

Abstract
The first 6 months after exposure to hepatitis C virus (HCV) are regarded as acute hepatitis C (AHC). Two patient populations worldwide share the highest prevalence of AHC virus infection: injection drug users and HIV-positive men who have sex with men. Diagnosis of AHC is often difficult in both patient populations as the acute inflammatory phase can be clinically asymptomatic and patients at highest risk for acquiring AHC (injection drug users) tend to evade regular medical care. This article addresses similarities and differences in the epidemiology, diagnosis, and management of AHC monoinfection and coinfection.

Abstract
Background Hepatitis C virus (HCV) emerged as sexually transmitted infection among HIV-infected men who have sex with men (MSM). We studied whether HCV circulated in identifiable high-risk MSM subcultures and performed phylogenetic analysis. Methods HIV-infected MSM were recruited at the sexually transmitted infections (STI) outpatient clinic and a university HIV clinic in Amsterdam, the Netherlands, 2008–2009. Participants completed a detailed questionnaire and were tested for HCV antibodies and RNA, with NS5B regions sequenced for analysis of clusters. Results Among 786 participants, the median age was 43 (IQR 37–48) years, and 93 (11.8%) were HCV-positive. Seropositivity was associated with belonging to subcultures identified as leather (aOR 2.60; 95% CI 1.56–4.33), rubber/lycra (aOR 2.15; 95% CI 1.10–4.21), or jeans (aOR 2.23; 95% CI 1.41–3.54). The two largest HCV-RNA monophyletic clusters were compared; MSM in cluster I (genotype 1a, n = 13) reported more partners (P = 0.037) than MSM in cluster II (genotype 4d, n = 14), but demographics, subculture characteristics and other risk behaviors did not differ significantly between the two clusters. Discussion HCV infection is associated with identifiable groups of leather/rubber/lycra/jeans subcultures among HIV-infected MSM. Separate epidemiological HCV transmission networks were not revealed. Active HCV screening and treatment within specific subcultures may reduce HCV spread among all MSM.

Abstract
BACKGROUND Sexually transmitted hepatitis C virus (HCV) infection is an emerging epidemic among human immunodeficiency virus (HIV)-infected men who have sex with men (MSM). HCV may be underrecognized in this population, historically thought to be at low risk. METHODS We determined the prevalence and incidence of HCV among HIV-infected men at Fenway Health between 1997 and 2009. We describe characteristics associated with HCV. RESULTS Of 1171 HIV-infected men, of whom 96% identify as MSM, 1068 (91%) were screened for HCV and 64 (6%) had a positive HCV antibody (Ab) result at initial screening. Among the 995 men whose initial HCV Ab result was negative, 62% received no further HCV Ab testing. Among the 377 men who had ≥1 additional HCV Ab test, 23 (6%) seroconverted over 1408 person-years, for an annualized incidence of 1.63 per 100 person-years (95% confidence interval, .97-2.30). Among the 87 HIV-infected MSM diagnosed with prevalent or incident HCV, 33% reported history of injection drug use, 46% noninjection drug use (NIDU), and 70% sexually transmitted infections (STIs). Sixty-four (74%) of HCV-infected MSM developed chronic HCV; 22 (34%) initiated HCV treatment and 13 (59%) of treated persons achieved a sustained virologic response (SVR). CONCLUSIONS Prevalent and incident HCV, primarily acquired through nonparenteral means, was common in this HIV-infected population despite engagement in care. STIs and NIDU were common among HIV/HCV-coinfected MSM. SVR rates were high among those who underwent HCV treatment. All sexually active and/or substance-using HIV-infected MSM should receive routine and repeated HCV screening to allow for early diagnosis and treatment of HCV.

Abstract
Deaths from hepatitis C virus (HCV)-related disease are increasing, now exceeding those from human immunodeficiency virus. Up to 7 million Americans (2.3%) may be infected with HCV, and more than half are undiagnosed. Proposed expansion of hepatitis C screening to include all persons born between 1945 and 1965 will lead to many new diagnoses, and infectious diseases physicians have a unique opportunity to be part of managing these patients. Apart from a liver-focused history and examination, the initial evaluation includes determination of the liver function via serum tests and assessment of liver fibrosis and necroinflammation through biopsy or noninvasive means. Patients with cirrhosis require screening for esophageal varices and for liver cancer. Nonimmune patients need vaccinations against hepatitis A and B, and alcohol abstinence is critical. Initial counseling on therapy emphasizes viral cure rates of currently 70%-80% as well as expected side effects. New treatments with fewer side effects and potentially higher cure rates are currently in development.

Abstract
BACKGROUND & AIMS Case definitions for recent hepatitis C virus (HCV) infection vary considerably between studies. The aim of this systematic review was to characterize case definitions for recent HCV and explore the heterogeneity in studies performed to date. METHODS A systematic literature search of MEDLINE, SCOPUS, and ISI Web of Knowledge was performed covering all studies of recent HCV infection cited between January 2000 and June 2011. The criteria used by each study to define cases of recent HCV infection were extracted, structured, and analyzed. RESULTS Overall, 195 articles were included, with 87% (n=169) providing a clear case definition for recent HCV infection. The most frequently used individual criteria for defining a case included HCV antibody seroconversion (77%), alanine aminotransferase (ALT) elevation (68%), and HCV RNA detection (63%). In studies using HCV antibody seroconversion, the window period between the last negative and the first positive antibody test varied widely across studies (4 weeks to 4 years). Considerable diversity was also observed with respect to the ALT threshold used to characterize ALT elevations, ranging from 2 to 20 times the upper limit of normal. HCV antibody seroconversion was used as a single criterion in 41% of the studies, while all other studies used at least two criteria (range: 2-9). Epidemiology/surveillance studies mostly used a more sensitive case definition, whereas treatment studies, natural history studies, and diagnosis studies used more specific case definitions. CONCLUSIONS Marked heterogeneity in case definitions for recent HCV infection was observed. Although a single case definition for recent HCV is not warranted, a degree of standardization within specific study categories would enable improved cross-study comparison and more uniform evaluation of HCV prevention and management strategies.

Abstract
PURPOSE OF REVIEW In recent years outbreaks of sexually acquired acute hepatitis C virus infections have been observed in HIV-infected men who have sex with men. The reasons are unclear as both viruses have been known for more than a decade and sexual transmission of hepatitis C has been rare. RECENT FINDINGS For effective sexual transmission of hepatitis C several factors comprising HIV infection, concomitant sexually transmitted infections and sexual practices with a risk of mucosal damage appear to be important. Sexual transmissions have also been described in HIV-negative individuals, underlining the fact that the degree of mucosal damage, facilitating blood to blood transmission, is the key risk factor. After acquisition of acute hepatitis C a spontaneous resolution is observed in 25% of HIV-infected individuals. Early treatment with pegylated interferon and ribavirin results in sustained virological response rates in 60-75% of patients. SUMMARY Sexual transmission of hepatitis C has occurred more frequently in recent years within a highly selected population. A surge of classic sexually transmitted infections as well as behavioural changes appear to have fuelled this epidemic.

Abstract
PURPOSE OF REVIEW Persons with HIV are frequently coinfected with hepatitis C virus. We review recent data on the epidemiology and natural history of hepatitis C in HIV-infected persons. RECENT FINDINGS One-quarter of persons with HIV in Europe and the USA also have hepatitis C, but its prevalence in other areas is under 10%. Outbreaks of acute hepatitis C among men having sex with men have been described in Europe. Hepatitis C is the cause of more than three-quarters of liver-related deaths in HIV-seropositive individuals; however, liver-related morbidity and mortality are declining or stable in the era of highly active antiretroviral therapy. The association between hepatitis C virus coinfection and non-liver-related morbidity and mortality is still controversial. HIV-induced immune depression is strongly associated with worse liver disease, but it still does not support an earlier initiation of highly active antiretroviral therapy in coinfected subjects. SUMMARY Screening and management of hepatitis C virus coinfection should be mandatory in persons with HIV, especially in Europe and the USA, where prevention of blood exposure should also be pursued in patients with sexual risk behaviour. The results of ongoing randomized controlled trials are needed before recommending earlier initiation of highly active antiretroviral therapy in coinfected persons.

Abstract
An estimated 4 to 5 million people are co-infected with HIV/HCV worldwide. Recently observed outbreaks of acute HCV infection among HIV-positive men who have sex with men (MSM) have been linked to behavioral factors such as high risk sexual practices and recreational drug use. However, at the molecular level, many drugs such as glucocorticoids or cyclosporine A have been found to modulate viral replication. Thus, it is conceivable that drugs used in highly active antiretroviral therapy (HAART) may heighten susceptibility to HCV infection and contribute to the recent outbreaks. We therefore performed a comprehensive screen of antiretroviral drugs covering all available drug classes both individually and in typical combinations used during HAART to probe for direct effects on HCV cell entry, replication, new particle assembly and release. Importantly, no significant enhancement or inhibition of HCV cell entry, replication or new particle production was detected. While raltegravir and ritonavir boosted atazanavir reduce HCV replication, a tenfold reduction of HCVcc entry by the CCR5 antagonist maraviroc was observed. In conclusion, commonly used HAART agents do not specifically enhance HCV replication. Thus recent epidemic outbreaks of acute HCV in HIV-infected MSM are unlikely to be related to enhancing effects of HAART drugs.

Abstract
It is estimated that 4-5 million HIV-infected patients are coinfected with HCV. The impact of HIV on the natural course of HCV infection is deleterious. This includes a higher rate of HCV persistence and a faster rate of fibrosis progression. Coinfected patients show poor treatment outcome following standard HCV therapy. Although direct antiviral agents offer new therapeutic options, their use is hindered by potential drug interactions and toxicity in HIV-infected patients under HAART. Overtime, a large reservoir of HCV genotype 1 patients will accumulate in resource poor countries where the hepatitis C treatment is not easily affordable and HIV therapy remains the primary health issue for coinfected individuals. HCV vaccines represent a promising strategy as an adjunct or alternative to current HCV therapy. Here, the authors review the pathogenesis of hepatitis C in HIV-infected patients, with a focus on the impact of HIV on HCV-specific immune responses and discuss the challenges for vaccine development in HIV-HCV coinfection.

Abstract
BACKGROUND Community-acquired methicillin-resistant Staphylococcus aureus (caMRSA) skin and soft-tissue infections are a major cause for concern. Communities of men who have sex with men (MSM) in the USA being prone to caMRSA epidemics, we investigated whether MSM attending our sexually transmitted disease clinic were carriers of or infected by caMRSA. METHODS 300 MSM were prospectively recruited, interrogated and examined. Swabs of their nares and of their pubic and perineal skin were taken and cultured. RESULTS No evidence of carriage or infection by caMRSA was found. Nasal carriage of methicillin-sensitive S. aureus was within French estimates. Perineal carriage significantly correlated with the number of sexual partners. CONCLUSION Although caMRSA carriage or infection does not seem to affect Paris MSM, prospective sampling may not be the best method to monitor them. The correlation between number of partners and perineal carriage suggests that thorough hygiene after intercourse could limit the spread of S. aureus in MSM with multiple partners.

Abstract
BACKGROUND We used a Monte Carlo computer simulation to estimate the effectiveness and cost-effectiveness of screening for acute hepatitis C virus (HCV) infection in human immunodeficiency virus (HIV)-infected men who have sex with men. METHODS One-time screening for prevalent HCV infection was performed at the time of enrollment in care, followed by either symptom-based screening, screening with liver function tests (LFTs), HCV antibody (Ab) screening, or HCV RNA screening in various combinations and intervals. We considered both treatment with pegylated interferon and ribavirin (PEG/RBV) alone and with an HCV protease inhibitor. Outcome measures were life expectancy, quality-adjusted life expectancy, direct medical costs, and cost-effectiveness, assuming a societal willingness to pay $100000 per quality-adjusted life-year (QALY) gained. RESULTS All strategies increased life expectancy (from 0.49 to 0.94 life-months), quality-adjusted life expectancy (from 0.47 to 1.00 quality-adjusted life-months), and costs (from $1900 to $7600), compared with symptom-based screening. The incremental cost-effectiveness ratio of screening with 6-month LFTs and a 12-month HCV Ab test, compared with symptom-based screening, was $43 700/QALY (for PEG/RBV alone) and $57 800/QALY (for PEG/RBV plus HCV protease inhibitor). The incremental cost-effectiveness ratio of screening with 3-month LFTs, compared with 6-month LFTs plus a 12-month HCV Ab test, was $129 700/QALY (for PEG/RBV alone) and $229 900/QALY (for PEG/RBV plus HCV protease inhibitor). With HCV protease inhibitor-based therapy, screening with 6-month LFTs and a 12-month HCV Ab test was the optimal strategy when the HCV infection incidence was ≤1.25 cases/100 person-years. The 3-month LFT strategy was optimal when the incidence was >1.25 cases/100 person-years. CONCLUSIONS Screening for acute HCV infection in HIV-infected MSM prolongs life expectancy and is cost-effective. Depending on incidence, regular screening with LFTs, with or without an HCV Ab test, is the optimal strategy.

J Clin Microbiol 2012; 50:781-7. [PMID: 22189113 PMCID: PMC3295121 DOI: 10.1128/jcm.06014-11] [Citation(s) in RCA: 66] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2011] [Accepted: 12/09/2011] [Indexed: 02/07/2023] Open
Abstract
Outbreaks of sexually transmitted hepatitis C virus (HCV) infections have been recently reported in HIV-infected men who have sex with men (MSM) in Europe, Australia, and North America. Little is known concerning whether this also occurs in other Asia-Pacific countries. Between 1994 and 2010, a prospective observational cohort study was performed to assess the incidence of recent HCV seroconversion in 892 HIV-infected patients (731 MSM and 161 heterosexuals) who were not injecting drug users. A nested case-control study was conducted to identify associated factors with recent HCV seroconversion, and phylogenetic analysis was performed using NS5B sequences amplified from seroconverters. During a total followup duration of 4,270 person-years (PY), 30 patients (3.36%) had HCV seroconversion, with an overall incidence rate of 7.03 per 1,000 PY. The rate increased from 0 in 1994 to 2000 and 2.29 in 2001 to 2005 to 10.13 per 1,000 PY in 2006 to 2010 (P < 0.05). After adjustment for age and HIV transmission route, recent syphilis remained an independent factor associated with HCV seroconversion (odds ratio, 7.731; 95% confidence interval, 3.131 to 19.086; P < 0.01). In a nested case-control study, seroconverters had higher aminotranferase levels and were more likely to have CD4 ≥ 200 cells/μl and recent syphilis than nonseroconverters (P < 0.05). Among the 21 patients with HCV viremia, phylogenetic analysis revealed 7 HCV transmission clusters or pairs (4 within genotype 1b, 2 within genotype 2a, and 1 within genotype 3a). The incidence of HCV seroconversion that is associated with recent syphilis is increasing among HIV-infected patients in Taiwan.

Gaining greater insight into HCV emergence in HIV-infected men who have sex with men: the HEPAIG Study. PLoS One 2011; 6:e29322. [PMID: 22216248 PMCID: PMC3245268 DOI: 10.1371/journal.pone.0029322] [Citation(s) in RCA: 43] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2011] [Accepted: 11/24/2011] [Indexed: 12/19/2022] Open
Abstract
Objectives The HEPAIG study was conducted to better understand Hepatitis C virus (HCV) transmission among human immuno-deficiency (HIV)-infected men who have sex with men (MSM) and assess incidence of HCV infection among this population in France. Methods and Results Acute HCV infection defined by anti-HCV or HCV ribonucleic acid (RNA) positivity within one year of documented anti-HCV negativity was notified among HIV-infected MSM followed up in HIV/AIDS clinics from a nationwide sampling frame. HIV and HCV infection characteristics, HCV potential exposures and sexual behaviour were collected by the physicians and via self-administered questionnaires. Phylogenetic analysis of the HCV-NS5B region was conducted. HCV incidence was 48/10 000 [95% Confidence Interval (CI):43–54] and 36/10 000 [95% CI: 30–42] in 2006 and 2007, respectively. Among the 80 men enrolled (median age: 40 years), 55% were HIV-diagnosed before 2000, 56% had at least one sexually transmitted infection in the year before HCV diagnosis; 55% were HCV-infected with genotype 4 (15 men in one 4d-cluster), 32.5% with genotype 1 (three 1a-clusters); five men were HCV re-infected; in the six-month preceding HCV diagnosis, 92% reported having casual sexual partners sought online (75.5%) and at sex venues (79%), unprotected anal sex (90%) and fisting (65%); using recreational drugs (62%) and bleeding during sex (55%). Conclusions This study emphasizes the role of multiple unprotected sexual practices and recreational drugs use during sex in the HCV emergence in HIV-infected MSM. It becomes essential to adapt prevention strategies and inform HIV-infected MSM with recent acute HCV infection on risk of re-infection and on risk-reduction strategies.
