Abstract
OBJECTIVES To eliminate hepatitis B and C virus (HBV/HCV) as a public health threat by 2030, the WHO focuses on screening key populations, including men who have sex with men (MSM).This study aims to assess HBV and HCV knowledge and awareness and HCV prevalence in MSM in Belgium. METHODS First, a questionnaire was designed to assess MSM's knowledge of HBV and HCV infection (disease process, vaccination, treatment and transmission routes). This questionnaire was conducted online, and by means of a tablet-based face-to-face questionnaire at the Antwerp and Belgian Pride. Second, HCV and HIV prevalence data were collected during outreach projects and office screening for sexually transmitted infections (STIs) organised by Sensoa and Exaequo, a Flemish and Walloon sexual health organisation. RESULTS 300 MSM completed the questionnaire (median age 36 years; 7.7% HIV+). Mean overall survey scores were low (HBV: 41.1%; HCV: 39.8%). Few participants identified all transmission routes correctly (HBV: 15%; HCV 1%).The degree of education was significantly correlated with HBV knowledge and showed a trend towards correlation with HCV knowledge. HCV knowledge was significantly correlated with high-risk sexual behaviour.The prevalence of HCV and HIV was 0.3% and 1.0%, respectively, in MSM attending commercial gay venues and 0% and 1.9% in MSM attending office STI screening. CONCLUSIONS Knowledge of HBV and HCV infection in MSM is poor. More awareness campaigns are needed, focusing on frequent HCV risk factors (group sex, chemsex, receptive fisting, and sharing of anal toys and anal douching devices), especially targeting low-educated MSM. HBV vaccination of MSM requires continued attention.The prevalence of HCV and HIV was remarkably low in commercial gay venues and may be higher in older MSM or in subcultures where risk factors coexist (eg, chemsex). The cost-effectiveness of internet-based approaches with subsequent at-home testing needs to be evaluated in the future.

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
OBJECTIVES To identify sexual/sex-associated risk factors for hepatitis C transmission among men who have sex with men (MSM) and visualise behavioural trajectories from 2019 to 2021. METHODS We linked a behavioural survey to a hepatitis C cohort study (NoCo), established in 2019 across six German HIV/hepatitis C virus (HCV) treatment centres, and performed a case-control analysis. Cases were MSM with recent HCV infection, and controls were matched for HIV status (model 1) or proportions of sexual partners with HIV (model 2). We conducted conditional univariable and multivariable regression analyses. RESULTS In all, 197 cases and 314 controls completed the baseline questionnaire and could be matched with clinical data. For regression models, we restricted cases to those with HCV diagnosed since 2018 (N = 100). Factors independently associated with case status included sex-associated rectal bleeding, shared fisting lubricant, anal douching, chemsex, intravenous and intracavernosal injections, with population-attributable fractions of 88% (model 1) and 85% (model 2). These factors remained stable over time among cases, while sexual partner numbers and group sex decreased during COVID-19 measures. CONCLUSIONS Sexual/sex-associated practices leading to blood exposure are key factors in HCV transmission in MSM. Public health interventions should emphasize the importance of blood safety in sexual encounters. Micro-elimination efforts were temporarily aided by reduced opportunities for sexual encounters during the COVID-19 pandemic.

HBV and HCV Co-Infection in Chinese Newly Diagnosed HIV+ Subjects in 2015 and 2023: A Cross-Sectional Study. Pathogens 2024; 13:367. [PMID: 38787219 PMCID: PMC11124262 DOI: 10.3390/pathogens13050367] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Revised: 04/10/2024] [Accepted: 04/12/2024] [Indexed: 05/25/2024] Open
Abstract
With shared routes of transmission, HBV and HCV co-infection are estimated to occur more in subjects with HIV. This study aimed to characterize and describe the prevalence of HBV and HCV co-infections in a cohort of newly diagnosed HIV+ subjects living in China. We conducted a cross-sectional study among newly diagnosed HIV+ subjects aged 18-100 who participated in surveys on the national HIV molecular epidemiology in 2015 and 2023. (The epidemiological table survey is located in the national database alongside serologic testing). The chi-square test was used to identify changes in infections between the studying populations in 2015 and 2023, and conditional logistic regression models were fit to identify risk factors for each co-infection. Among the 11,024 newly diagnosed HIV+ subjects who were surveyed (n = 4501 in 2015; n = 6523 in 2023), the prevalence of HBV, HCV, and HBV/HCV in 2023 was lower than that in 2015, respectively. No decrease was observed in HCV co-infection in men who had sex with men (MSM) in North China, Northeast China, and East China. Increasing recognition among those at high risk of heterosexual transmission and those with low educational backgrounds is paramount to the prevention and control of HIV/HBV/HCV infections.

Hepatitis C (HCV) among Black and Latino sexual minority men (SMM) in the Southern United States: Protocol of a prospective cohort epidemiological study. PLoS One 2023; 18:e0288129. [PMID: 37410770 PMCID: PMC10325100 DOI: 10.1371/journal.pone.0288129] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2022] [Accepted: 06/20/2023] [Indexed: 07/08/2023] Open
Abstract
BACKGROUND Sexual minority men (SMM) who engage in condomless anal sex and injection drug use are at increased risk for viral Hepatitis C (HCV) infection. Additionally, studies have found racial disparities in HCV cases across the United States. However, very few epidemiological studies have examined factors associated with HCV infection in HIV-negative Black and Latino SMM. This paper describes the rationale, design, and methodology of a prospective epidemiological study to quantify the HCV prevalence and incidence and investigate the individual and environmental-level predictors of HCV infection among HIV-negative, Black and Latino SMM in the Southern U.S. METHODS Beginning in September 2021, 400 Black and Latino SMM, aged 18 years and above, will be identified, recruited and retained over 12-months of follow-up from two study sites: greater Washington, DC and Dallas, TX areas. After written informed consent, participants will undergo integrated HIV/STI testing, including HCV, HIV, syphilis, gonorrhea, and chlamydia. Subsequently, participants will complete a quantitative survey-including a social and sexual network inventory-and an exit interview to review test results and confirm participants' contact information. Individual, interpersonal, and environmental factors will be assessed at baseline and follow-up visits (6 and 12 months). The primary outcomes are HCV prevalence and incidence. Secondary outcomes are sexual behavior, substance use, and psychosocial health. RESULTS To date (March 2023) a total of 162 participants have completed baseline visits at the DC study site and 161 participants have completed baseline visits at the Texas study site. CONCLUSION This study has several implications that will directly affect the health and wellness of Black and Latino SMM. Specifically, our results will inform more-focused HCV clinical guidelines (i.e., effective strategies for HCV screening among Black/Latino SMM), intervention development and other prevention and treatment activities and development of patient assistance programs for the treatment of HCV among uninsured persons, especially in Deep South, that have yet to expand Medicaid.

Risk factors for HCV transmission in HIV-positive men who have sex with men in México. PLoS One 2022; 17:e0269977. [PMID: 35839163 PMCID: PMC9286238 DOI: 10.1371/journal.pone.0269977] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2021] [Accepted: 06/01/2022] [Indexed: 11/19/2022] Open
Abstract
Purpose
In the last two decades transmission of hepatitis C virus (HCV) in HIV positive men who have sex with men (MSM) has been reported globally. Chemsex and specific sexual practices have been identified as risk factors. Our study aimed to identify risk factors for HCV transmission in MSM living with HIV attending in Mexico.
Methods
We conducted a case-control study from April to December 2019 at the Hospital de Infectología “La Raza” National Medical Center, in Mexico City. A case was defined as an HIV-infected MSM with positive HCV-antibody test. For each case, 3 controls were included, defined as HIV infected MSM with negative HCV-antibody test. A self-questionnaire covering sexual practices and other risk factors for HCV transmission was applied. Bivariate analysis was performed to obtain odds ratio (OR) using Chi-square test. Independent risk factors were identified in a subsequent analysis performing a logistic regression model.
Results
A total of 324 patients participated in the study, 81 cases and 243 controls. Median age was 30.5 years (IQR: 18–52) and 28.8 years (IQR: 21–45) in the case and control group, respectively. Most prevalent HCV genotype was 1a (79%). In the logistic regression model, sharing straw during cocaine inhalation (OR: 9.03; 95% CI; 1.35–13.52; P = 0.003), sharing sex toys (OR: 17.53, 95% CI; 6.85–44.86; P = 0.002), and ethyl chloride use for chemsex (OR: 2.26; 95% CI; 1.29–5.56; P = 0.037) were significant risk factors for HCV infection.
Conclusion
This study identifies risk factors for HCV transmission in Mexico in HIV positive MSM in congruence with the findings of many studies performed worldwide. This is the first study that indicates a possible association between ethyl chloride use in chemsex and HCV infection. Assessment of local populations for risk factors for HCV transmission may help to develop specifically targeted behavioral interventions to reduce HCV transmission.

Abstract
HIV/hepatitis C virus (HCV) coinfection is a global health problem with overlapping modes of transmission. We performed a single-center retrospective case series of acute HCV infections at the Atlanta Veterans Affairs Health Care System between January 2001 and June 2020 to better characterize the presentation and clinical course of acute HCV among veterans with HIV. Cases were discovered through routine clinical care. We identified 29 cases of acute HCV: all men. Risk for HCV acquisition included men who have sex with men (MSM; 93%) and injection drug use (17%). Thirteen (45%) had a concurrent sexually transmitted infection (STI). Symptoms were seen in 76% of acute HCV cases and resulted in hospitalization in 59% of symptomatic cases. Seven (24%) presented as HCV antibody seronegative. Three never seroconverted, all with CD4 T cell counts <200. Spontaneous HCV clearance occurred in 21% (n = 6) and was more common in those who developed jaundice (p = 0.01). Time to treatment was significantly reduced in the direct-acting antivirals (DAAs) era versus the interferon era (300 vs. 1631 days, p < 0.01). Of those who did not spontaneously clear, 87% were treated (n = 20/23) and 95% (n = 19/20) achieved sustained virological response. Three patients died before HCV treatment, all in the pre-DAA period (one death was liver related). In this case series of acute HCV infection in persons with HIV, many were symptomatic MSM who had a concurrent STI, suggesting sexual HCV transmission. Some presented as HCV antibody negative, highlighting the role of enhanced HCV screening and treatment in MSM with HIV to prevent HCV transmission in sexual networks.

Abstract
Background: The disease burden of hepatitis C virus (HCV) infection in HIV-positive and HIV-negative men who have sex with men (MSM) is changing. We aim to provide an updated comprehensive estimate of HCV prevalence and incidence among the HIV-positive and HIV-negative MSM population at the country, regional, and global levels and their changing trends over time. Methods: PubMed, Embase, PsycINFO, CINAHL, and conference databases were searched and eligible records on the prevalence and incidence of HCV antibodies were selected and pooled via a random-effects model. Meta-regression was performed to demonstrate the association between the pooled rates and study year. Results: A total of 230 articles reporting 245 records from 51 countries with 445,883 participants and 704,249 follow-up person-years were included. The pooled prevalence of HCV in MSM was 5.9% (95% CI: 5.1-6.8), with substantial differences between countries and regions. Low- and lower-middle-income countries (12.3 and 7.0%) manifested a larger disease burden than high- and upper-middle-income countries (5.8 and 3.8%). HCV prevalence in HIV-positive MSM was substantially higher than in HIV-negative MSM (8.1 vs. 2.8%, p < 0.001). The pooled incidence of HCV was 8.6 (95% CI: 7.2-10.0) per 1,000 person-years, with an increasing trend over time, according to meta-regression (p < 0.05). Conclusion: Global HCV prevalence in MSM varies by region and HIV status. Behavior counseling and regular HCV monitoring are needed in HIV-positive subgroups and high-risk regions. Given the upward trend of HCV incidence and sexual risk behaviors, there is also a continued need to reinforce risk-reduction intervention.

Abstract
This study aimed to evaluate the influence of bareback sexually explicit media (SEM) consumption on anal sex without a condom by men who have sex with men (MSM). To this end, a page was created on the Facebook® social network with a link that directed interested parties to a questionnaire. Cisgender men, aged 18 years and over, who had sex with other men in the last 12 months, were included. Data were collected in 2017 and analyzed using univariate and bivariate inferential statistics and multivariate logistic regression. A total of 2,248 MSM participated in the research, with a mean age of 24.4 years and a mean number of 3.9 partners in the last 30 days. Having multiple sexual partners (ORa: 9.4; 95% CI 3.9-22.4), preferring movies with bareback scenes (ORa: 2.6; 95% CI 1.5-4.6), considering this practice a fetish and realizing it (ORa: 3.52; 95% CI 2.3-5.4), having casual partnerships (ORa: 1.8; 95% CI 1.5-1.9) and being aware of the partner's negative serological status for HIV (ORa: 1.4; 95% CI 1.1-2.3) were factors that increased the likelihood of engaging in anal sex without a condom. Thus, we found an association between the consumption of bareback SEM and sex without a condom among MSM.

Abstract
Objectives: To assess the impact of Pre-Exposure Prophylaxis (PrEP) to avoid HIV infection as an additional service in a routine Sexually Transmitted Infections (STI) clinic.Methods: We used routinely obtained retrospective data to estimate the increased workload on the existing facilities. We focussed on STI registration through the laboratory registration system and put this in a national perspective. A critical appraisal was made of the national HIV notifications, as an indicator of the impact of PrEP. Additional challenges were identified via face-to-face interviews with clinicians with at least five years experience in the STI clinic.Results: PrEP delivery puts a substantial burden on a routine STI clinic, in terms of counselling users and prescribing drugs, and regular screening and treating of STIs. Psycho-social aspects need to be incorporated as part of a comprehensive approach of the PrEP user. This requires skills and resources that are not yet always available in a clinic, specialised in HIV and STI care. The increasing demand for this service calls for a careful and critical appraisal of the existing service model.Conclusion: PrEP has gained an important and irreplaceable position in the prevention of HIV infection. New models of care need to be studied, preferably in close collaboration with the users, to make this intervention sustainable for the health system in which it is introduced.

Abstract
BACKGROUND Human immunodeficiency virus (HIV)-positive men who have sex with men (MSM) are at high risk of hepatitis C virus (HCV) reinfection following clearance of HCV, but risk factors specifically for reinfection have never been comprehensively assessed. METHODS Using data from a prospective observational cohort study among HIV-positive MSM with an acute HCV infection (MOSAIC), the incidence of HCV reinfection following spontaneous clearance or successful treatment was assessed. A univariable Bayesian exponential survival model was used to identify risk factors associated with HCV reinfection. RESULTS In total, 122 HIV-positive MSM who had a spontaneously cleared or successfully treated HCV infection between 2003 and 2017 were included. During a median follow-up of 1.4 years (interquartile range [IQR] 0.5-3.8), 34 HCV reinfections were observed in 28 patients. The incidence of HCV reinfection was 11.5/100 person-years and among those with reinfection, median time to reinfection was 1.3 years (IQR 0.6-2.7). HCV reinfection was associated with receptive condomless anal intercourse, sharing of sex toys, group sex, anal rinsing before sex, ≥10 casual sex partners in the last 6 months, nadir CD4 cell count <200 cells/mm3, and recent CD4 cell count <500 cells/mm3. CONCLUSIONS Incidence of HCV reinfection was high and strongly associated with sexual risk behavior, highlighting the need for interventions to reduce risk behavior and prevent HCV reinfections among HIV-positive MSM.

Abstract
These guidelines for the treatment of persons who have or are at risk for
sexually transmitted infections (STIs) were updated by CDC after consultation
with professionals knowledgeable in the field of STIs who met in Atlanta,
Georgia, June 11–14, 2019. The information in this report updates the
2015 guidelines. These guidelines discuss 1) updated recommendations for
treatment of Neisseria gonorrhoeae, Chlamydia trachomatis,
and Trichomonas vaginalis; 2) addition of
metronidazole to the recommended treatment regimen for pelvic inflammatory
disease; 3) alternative treatment options for bacterial vaginosis; 4) management
of Mycoplasma genitalium; 5) human papillomavirus vaccine
recommendations and counseling messages; 6) expanded risk factors for syphilis
testing among pregnant women; 7) one-time testing for hepatitis C infection; 8)
evaluation of men who have sex with men after sexual assault; and 9) two-step
testing for serologic diagnosis of genital herpes simplex virus. Physicians and
other health care providers can use these guidelines to assist in prevention and
treatment of STIs.

Clin Infect Dis 2021; 71:1248-1254.

Abstract
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.

Response to a sexual risk reduction intervention provided in combination with hepatitis C treatment by HIV/HCV co-infected men who have sex with men: a reflexive thematic analysis. BMC Infect Dis 2021; 21:319. [PMID: 33823783 PMCID: PMC8022541 DOI: 10.1186/s12879-021-06003-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Accepted: 03/16/2021] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Hepatitis C virus reinfections in HIV-positive men-who-have-sex-with-men (MSM) challenge the effectiveness of antiviral treatment. To fight this problem, an adapted sexual risk reduction intervention was implemented within a hepatitis C treatment trial. Following this, the current study had two aims and describes 1) how the program was received by participants; and 2) their responses to the program regarding sexual risk taking. Based on the participants' input, we hoped to judge the intervention's potential for scale-up. METHODS Seventeen participants who received the sexual risk reduction intervention in addition to hepatitis C treatment were recruited for semi-structured interviews six to 12 months post-intervention. We evaluated the responses via reflexive thematic analysis and applied the concept of sense-making. RESULTS Giving hepatitis C a place and living without it again illustrates how participants received the program and how their experiences were altered by the impact of sense-making. Based on their responses, we allocated participants to three groups: 1. Avoid risks: get rid of hepatitis C for life. For these men, hepatitis C remained a life-threatening disease: they actively modified their risk behavior and felt supported by the intervention in maintaining their behavioral changes. 2. Minimize risks: live as long as possible without hepatitis C. In contrast to group 1, these men saw hepatitis C as a manageable disease. The intervention facilitated reflection on risks and how to develop behavioral changes that suited them individually. 3. Accept risks; live with the risk of hepatitis C. These men perceived behavioral changes as much more difficult than "easy" medical treatment. They expected to either undergo repeated rounds of treatment or stay HCV re-infected. CONCLUSION These results illustrate the diversity of men's responses and their decisions regarding sexual risk behavior after participating in a combination of antiviral treatment and a sexual risk reduction intervention. Two major aspects were identified: 1) Teachable moments, particularly at the time of diagnosis/treatment, could offer an opportunity to develop openness for behavioral change; 2) adapting sexual risk reduction interventions to sense-making patterns could help to improve its effectiveness. Support for reducing infection risk and raising awareness of preventative measures are additional benefits. TRIAL REGISTRATION Clinical Trial Number: NCT02785666 , 30.05.2016.

Abstract
PURPOSE OF REVIEW The WHO has set ambitious targets for hepatitis C virus (HCV) elimination by 2030. In this review, we explore the possibility of HCV micro-elimination in HIV-positive (+) MSM, discussing strategies for reducing acute HCV incidence and the likely interventions required to meet these targets. RECENT FINDINGS With wider availability of directly acting antivirals (DAAs) in recent years, reductions in acute HCV incidence have been reported in some cohorts of HIV+ MSM. Recent evidence demonstrates that treatment in early infection is well tolerated, cost effective and may reduce the risk of onward transmission. Modelling studies suggest that to reduce incidence, a combination approach including behavioural interventions and access to early treatment, targeting both HIV+ and negative high-risk groups, will be required. HCV vaccine trials have not yet demonstrated efficacy in human studies, however phase one and two studies are ongoing. SUMMARY Some progress towards the WHO HCV elimination targets has been reported. Achieving sustained HCV elimination is likely to require a combination approach including early access to DAAs in acute infection and reinfection, validated and reproducible behavioural interventions and an efficacious HCV vaccine.

The hepatitis C cascade of care in the Belgian HIV population: One step closer to elimination. Int J Infect Dis 2021; 105:217-223. [PMID: 33610786 DOI: 10.1016/j.ijid.2021.02.068] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Revised: 02/16/2021] [Accepted: 02/16/2021] [Indexed: 12/14/2022] Open
Abstract
OBJECTIVES The Belgian population of people living with HIV (PLHIV) has unrestricted access to direct-acting antiviral (DAA) treatment for hepatitis C virus (HCV) infection, since 2017. International literature claims that half of the patients remain untreated in high-income countries with unrestricted access to DAA. This study was initiated to provide an overview of the present situation in Belgium and recommendations for HCV care in PLHIV in other regions. METHODS This was a retrospective, multicenter study of PLHIV in Belgium, from January 1, 2007 to December 31, 2018. The HCV cascade of care was examined. RESULTS Out of 4607 unique PLHIV, 322 (7.0%) tested positive for HCV antibody and HCV RNA positivity was seen in 289 (6.3%). Of those with a proven HCV infection, 207/289 (71.6%) initiated treatment. Of the 171 (82.6%) persons with a sustained virologic response (SVR), 16 (9.4%) subjects were reinfected. CONCLUSIONS We present a care cascade of 4607 PLHIV in Belgium. Treatment initiation and SVR rates were high compared to other regions. Implementation of a national HCV register to track progress and yearly screening, especially in PLHIV with high-risk behavior, remains crucial. Identifying reasons for not initiating treatment is necessary to achieve elimination of HCV in PLHIV by 2030.

Abstract
OBJECTIVES Previous studies have demonstrated that rectal douching (RD) is associated with HIV acquisition among men who have sex with men (MSM). However, the precise mechanism underlying the association between RD and HIV remains unclear. METHODS We recruited participants over WeChat from October 2017 to October 2018. Respondents received mailed HIV self-testing kits, uploaded images of HIV self-test results and completed an online electronic questionnaire simultaneously. The questionnaire assessed sociodemographic characteristics, RD practices and sexual risk behaviours. HIV status was measured as the result of the HIV self-testing. The Baron and Kenny statistical method was used to assess the association between RD and HIV, controlling for condomless anal intercourse (CAI) and rectal bleeding. RESULTS Of 1365 participants, 39.93% (545/1365) reported RD in the past 6 months, 60.07% had multiple male sexual partners and 43.08% had CAI in the past 6 months. The prevalence of HIV, based on self-testing, was 3.37% (46/1365). Multivariable logistic analysis showed RD was significantly associated with bottom sexual role (adjusted OR (aOR) 14.0; 95% CI 9.8 to 20.2), having multiple male sexual partners (aOR 1.8; 95% CI 1.4 to 2.2), CAI (aOR 1.3; 95% CI 1.0 to 1.6), rectal bleeding (aOR 2.0; 95% CI 1.6 to 2.6) and HIV infection (aOR 1.9; 95% CI 1.0 to 3.4). Baron and Kenny analysis found both CAI (aOR 2.2; 95% CI 1.2 to 4.1) and rectal bleeding (aOR 1.9; 95% CI 1.0 to 3.4) play a mediating role in the association between RD and HIV. CONCLUSIONS Our study results confirmed the relationship between RD and HIV, and found CAI and rectal bleeding mediated HIV infection in Chinese MSM who douched. Strategies should be encouraged to strengthen health education and reduce high-risk sexual behaviour in order to reduce the risk of HIV in MSM who use enemas. Rectal microbicides may represent an efficient means of providing HIV prophylaxis among MSM.

Abstract
: In response to growing evidence of an expanding epidemic of sexually acquired hepatitis C virus (HCV) infection in HIV-positive MSM, the European AIDS Treatment Network (NEAT) acute hepatitis C consensus panel developed their first recommendations for HCV prevention and care during a consensus conference in May 2010 in Paris, France. As then, two major breakthroughs have changed the landscape. First, directly acting antivirals (DAA) with high levels of tolerability and HCV cure rates of over 95% are now widely available and will play a large role in the goal of elimination of HCV by 2030 (WHO sector strategy). Second, landmark studies demonstrated that universal test and treatment (UTT) approach as well as the demonstration that HIV cannot be sexually transmitted from a person living with HIV with an undetectable viraemia [undetectable = untransmittable (U = U) campaign] and HIV preexposure prophylaxis (PrEP) are very effective HIV biomedical prevention strategies for MSM. The scale-up of these interventions has reduced HIV incidence in MSM and also changed patterns of sexual networks and behaviour, which has contributed to increased HCV incidence among HIV-negative MSM who were eligible for or on PrEP. These recent developments, together with new clinical and scientific insights, underscore the importance of updating the statements and recommendations for acute HCV in both HIV-positive and HIV-negative MSM. In June 2019, experts from different disciplines and organizations including community representatives participated at the second acute HCV consensus conference of NEAT Infectious Diseases (ID) in Amsterdam, the Netherlands.

Assessing routes of hepatitis C transmission in HIV-infected men who have sex with men using single genome sequencing. PLoS One 2020; 15:e0235237. [PMID: 32667919 PMCID: PMC7363067 DOI: 10.1371/journal.pone.0235237] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2020] [Accepted: 06/10/2020] [Indexed: 02/07/2023] Open
Abstract
The epidemic of hepatitis C virus (HCV) infection among HIV-infected men who have sex with men (MSM) is in its second decade, but the routes of transmission remain poorly understood. We hypothesized that by pairing single genome sequencing (SGS), to enumerate infecting HCV genomes (viruses), with detailed sexual and drug histories, we could gain insight into the routes of transmission among MSM. We used SGS to analyze blood specimens from eight HIV-infected MSM who had 10 episodes of acute (seronegative) or early HCV infections. Seven of eight men reported condomless receptive anal intercourse (CRAI), six with rectal exposure to semen, and all eight denied rectal trauma or bleeding. Of the 10 HCV infections, eight resulted from transmission of a single virus; one infection resulted from transmission of either one or a few (three or four) closely-related viruses; and one infection resulted from transmission of >10 distinct viruses. The participant infected by >10 viruses reported sharing injection equipment for methamphetamine during sex. Two other participants also injected methamphetamine during sex but they did not share injection equipment and were infected by a single virus. Conclusions: Most HCV infections of HIV-infected MSM without a history of either rectal trauma or bleeding or shared injection equipment were caused by a single virus. Intra-rectal exposure to semen during CRAI is therefore likely sufficient for HCV transmission among MSM. Conversely, rectal trauma or bleeding or shared injection equipment are not necessary for HCV transmission among MSM. These results help clarify routes of HCV transmission among MSM and can therefore help guide the design of much-needed behavioral and other interventions to prevent HCV transmission among MSM.

Abstract
Chronic hepatitis C affects millions of people worldwide and patients born between 1945 and 1965 are at elevated risk. Hepatitis C infection can lead to health complications including liver cirrhosis and hepatocellular carcinoma. Recent advancements in direct-acting antiviral treatments have placed the spotlight on primary care providers to identify undiagnosed patients with chronic hepatitis C for treatment and attaining a sustained-virologic response. Primary care providers do not routinely screen patients born between 1945 and 1965 for hepatitis C despite CDC recommendations. To evaluate the effectiveness of a hepatitis C screening protocol implemented in a primary care setting with no prior protocol. A multidisciplinary team was used to implement a hepatitis C screening protocol for patients born between 1945 and 1965 (birth cohort screening). A retrospective analysis was conducted to compare the rate of hepatitis C screening 2 years before and 2 years after the protocol was implemented. Frequency data were collected monthly and tracked in a run chart noting relevant events that affected screening. In the 2 years before the screening protocol began, 81 patients were screened (average = 3 per month); and in the 2 years after the intervention was implemented, a total of 637 patients were screened (average = 25 per month). The protocol was successful in increasing screening rates from 15 to 66% in the 2 years post-intervention. This quality improvement study demonstrated that targeting the birth cohort population was a successful method for increasing hepatitis C screening in a primary care clinic.

Abstract
Hepatitis C (HCV) and HIV have common modes of transmission but information about HCV transmission risk, prevention, and treatment among persons with coinfection is lacking. The Medical Monitoring Project produces nationally representative estimates describing adults with diagnosed HIV in the United States. Using medical record data recorded during 6/2013-5/2017, we identified persons with detectable HCV RNA documented during the past 24 months. Among persons with coinfection, we described HCV transmission risk factors and receipt of HCV prevention services during the past 12 months and prescription of HCV treatment during the past 24 months. Overall, 4.9% had documented active HCV coinfection, among whom 30.2% were men who have sex with men (MSM), 6.7% reported injection drug use, and 62.1% were prescribed HCV treatment. Among MSM, 45.5% reported condomless anal sex and 42.3% received free condoms. Among persons who used drugs, 30.8% received drug or alcohol counseling, and among persons who injected drugs, 79.2% received sterile syringes. Among persons with HIV/HCV coinfection, recent drug injection was uncommon and most received sterile syringes. However, 1 in 3 were MSM, of whom half reported recent HCV sexual transmission risk behaviors. More than one-third of those with coinfection were not prescribed curative HCV treatment.

Knowledge, attitudes and practices related to hepatitis C among gay and bisexual men in the era of direct-acting antivirals: implications for treatment and prevention. CULTURE, HEALTH & SEXUALITY 2020; 22:551-567.

Abstract
Increases in hepatitis C (HCV) infections among gay and bisexual men have recently been reported in a number of countries, with sexual transmission being the primary route of infection. Given that in countries such as Australia most gay and bisexual men living with HIV are already engaged in clinical care - as are an increasing number of HIV-negative men - there is potential for reducing onward HCV transmission through proactive testing and treatment. This study explored knowledge, attitudes and practices related to HCV among 194 gay and bisexual men collected through an online survey in Australia. Overall, respondents had high levels of HCV knowledge; however, only 76% knew about the availability of new treatments for HCV. Men's knowledge of their own HCV testing history was uncertain, with one in six unaware if they had ever been tested. Among men who reported recent drug injecting, one-third had been injected by someone else, and two-thirds had injected someone else, indicating a subculture of cross-administering within sexualised drug-use networks. We argue that the robust sexual, socio-cultural and clinical infrastructure that has been developed by - and for - gay and bisexual men around HIV care and prevention creates the potential for reducing HCV in this group.

Eliminating viral hepatitis C in Belgium: the micro-elimination approach. BMC Infect Dis 2020; 20:181. [PMID: 32106819 PMCID: PMC7045456 DOI: 10.1186/s12879-020-4898-y] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2019] [Accepted: 02/17/2020] [Indexed: 12/26/2022] Open
Abstract
Background Hepatitis C virus is one of the leading causes of chronic liver disease and liver-related deaths worldwide. The estimated prevalence of chronic hepatitis C viral infection among the general Belgian population was 0.57% (n = 64,000) in 2015. Although Belgium has had a ‘Hepatitis C Plan’ since 2014, elimination efforts are unclear. This study employs the best available data and modelling estimates to define the burden of hepatitis C viral infection among key subgroups in Belgium, identify information gaps and propose potential approaches to screening, linkage to care and treatment, and cure. Methods We examined the peer-reviewed and grey literature since 2012 for data on the prevalence of hepatitis C viral infection in Belgium in key subgroups identified by national experts and in the literature. Ultimately, this research is primarily based on data provided by the key stakeholders themselves due to a lack of reliable data in the literature. Based on this, we modelled the treatment rates required to reach elimination of hepatitis C in several subgroups. Results Eleven potential subgroups were identified. There were no data available for two subgroups: generational cohorts and men who have sex with men. In six subgroups, fewer than 3000 people were reported or estimated to have hepatitis C infection. Migrants and people who inject drugs were the most affected subgroups, and children were the least affected subgroup. Only two subgroups are on target to achieve elimination by 2030: patients living with haemophilia and transplant recipients. Conclusions Removing Belgian treatment reimbursement restrictions in January 2019 was a big step towards eliminating HCV. In addition, increasing surveillance, including with a national registry, treatment prescription by other health-care providers and availability of treatment in local pharmacies are central to improving the current situation and getting on track to reach the 2030 WHO hepatitis C elimination targets in Belgium.

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
The role of condomless anal intercourse (CAI) as a driver for the epidemic of hepatitis C in MSM is still debated. Timely access to direct-acting antivirals (DAA) could represent an essential strategy to tackle this. Case notes of MSM diagnosed with acute hepatitis C (AHC) between July 2016 and June 2017 in a sexual health clinic in London were included. Behavioural data on sexual practices and STI monitoring in the 6 months prior to AHC diagnosis were collected. DAA routes of access and timing from AHC diagnosis to start of treatment were analysed. A total of 60 individuals were enrolled (median age 39 years, IQR = 33-46, 62% HIV co-infected, 72% genotype 1a). CAI was reported by 97%, drug use prior to or during sex by 73%; 46% was diagnosed with a rectal STI and 29% with syphilis. About 37% did not report any HCV risk factors other than condomless anal sex. About 36% had a new rectal STI in the 6 months following AHC. About 82% accessed DAA treatment and median time from AHC to DAA start was 278 days for those following the NHS standard of care route, 132 days for those accessing DAA via participation in trials and 114 for those who had self-sourced DAA online (P < 0.0011). SVR12 was achieved in 100% of the patients who received DAA treatment.In conclusion, CAI is a significant risk factor for HCV acquisition in MSM, irrespective of their HIV status. Rapid and wider access to treatment with DAA could represent a powerful strategy to reduce onward transmission and risk of reinfection in MSM.

Association between rectal douching and HIV and other sexually transmitted infections among men who have sex with men: a systematic review and meta-analysis. Sex Transm Infect 2019; 95:428-436. [PMID: 31073094 DOI: 10.1136/sextrans-2019-053964] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2019] [Revised: 04/13/2019] [Accepted: 04/18/2019] [Indexed: 01/02/2023] Open
Abstract
BACKGROUND Men who have sex with men (MSM) are disproportionately affected by HIV and other STIs worldwide. Rectal douching, which is commonly used by MSM in preparation for anal sex, may increase the risk of HIV and other STIs by injuring the rectal mucosa. Results from individual studies reporting associations between rectal douching and HIV and other STIs among MSM are inconsistent. We performed a systematic review and meta-analysis to estimate the association between rectal douching and HIV and other STIs among MSM. METHODS We searched PubMed, Embase, Scopus and Web of Science for studies published from January 1970 to November 2018. Studies that reported ORs and 95% CIs of associations between rectal douching and infection with HIV/STIs, or reported enough data to calculate these estimates, were included. We assessed risk of bias using the Newcastle-Ottawa Scale. ORs were pooled using a random effects model. RESULTS Twenty-eight eligible studies were identified in our review, of which 24 (20 398 participants) were included in the meta-analysis. Rectal douching was associated with increased odds of infection with HIV (OR 2.80, 95% CI 2.32 to 3.39), and any STI other than HIV (including hepatitis B virus (HBV), hepatitis C virus (HCV), chlamydia, gonorrhoea, syphilis and human papillomavirus) (OR 2.46, 95% CI 1.95 to 3.11) among MSM. For specific STIs, douching was associated with increased odds of viral hepatitis (HBV, HCV) (OR 3.29, 95% CI 2.79 to 3.87), and chlamydia or gonorrhoea (OR 3.25, 95% CI 2.02 to 5.23). These associations remained significant in studies that adjusted for potential confounders. CONCLUSION Rectal douching may put MSM at increased risk for infection with HIV and other STIs. Longitudinal studies are needed to clarify this association, and health education materials should inform men of the potential for increased risk of infection with rectal douching.

Abstract
Despite high response rates associated to hepatitis C virus (HCV) treatment, no protective immunity is acquired, allowing for reinfection and continued infectiousness. Distinguishing between relapse and reinfection is crucial for patient counselling and to choose the most appropriate retreatment. Here, refined phylogenetic analysis using multiple genes served to assess genotype and reinfection for 53 patients for whom the virus was sampled before start of therapy and at time of sustained virological response evaluation at week 12. At baseline, genotypes were determined as HCV1a (41.5%), HCV1b (24.5%), HCV4 (18.9%) and HCV3a (15.1%), while six cases revealed to be discordantly assigned by phylogeny and commercial assays. Overall, 60.4% was co-infected with HIV. The large majority was classified as people who inject drugs (78.6%), often co-infected with HIV. Transmission was sexual in seven cases, of which five in HIV-positive men-who-have-sex-with-men. Overall, relapse was defined for 44 patients, while no conclusion was drawn for four patients. Five patients were reinfected with a different HCV strain, of which three with a different genotype, showing that phylogeny is needed not only to determine the genotype, but also to distinguish between relapse and intra-subtype reinfection. Of note, phylogenies are more reliable when longer fragments of the viral genome are being sequenced.

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
This guideline updates the 2010 European guideline for the management of hepatitis B and C virus infections. It is primarily intended to provide advice on testing, prevention and initial management of viral hepatitis B and C for clinicians working in sexual health clinical settings in European countries. The guideline is in a new question and answer format based on clinical situations, from which population/intervention/comparison/outcome questions were formulated. Updates cover areas such as epidemiology, point-of-care tests for hepatitis B, hepatitis C risk and 'chemsex', and HIV pre-exposure prophylaxis and hepatitis B. We have also included a short paragraph on hepatitis E noting there is no evidence for sexual transmission. The guideline has been prepared in accordance with the Europe protocol for production available at http://www.iusti.org/regions/europe/pdf/2017/ProtocolForProduction2017.pdf.

Abstract
Objective The study aimed to describe the evolution of the seroprevalence of hepatitis C virus (HCV) among human immunodeficiency virus (HIV)-positive patients included in two cohorts in Taiwan. Methods We retrospectively collected the information on demographic and clinical characteristics of 4,025 and 3,856 HIV-positive Taiwanese, who were aged 18 years or older at designated hospitals around Taiwan in 2004–2007, when an outbreak of HIV infection was occurring, and 2012–2016, when the outbreak was controlled with the implementation of harm reduction program, respectively. Comparisons of HCV seropositivity were made among different age and risk groups for HIV transmission between these two cohorts. Results The overall HCV seroprevalence of the 2004–2007 cohort and 2012–2016 cohort was 43.4% (1,288/2,974) and 18.6% (707/3,793), respectively (P<0.001). The HCV seroprevalence among injecting drug users (IDUs), though decreasing, was constantly high across the two cohorts, 96.4% and 94.0% (P = 0.02), respectively, and all age groups. In contrast, the corresponding figures among men who have sex with men (MSM) and heterosexuals in the two cohorts were 5.9% vs. 3.5% (P = 0.002) and 9.4% vs. 10.9% (P = 0.59), respectively. Among sexually transmitted HIV-positive patients, HCV seropositivity was significantly correlated with age (adjusted odds ratio [aOR], per 1-year increase, 1.03; 95% confidence interval [CI], 1.02–1.05) and a rapid plasma reagin (RPR) titer ≥1:8 (aOR, 1.58; 95% CI, 1.03–2.43) in a multivariate analysis including age, gender, route for HIV transmission, baseline CD4 count and plasma HIV RNA load, the presence of hepatitis B surface antigen, and an RPR titer ≥1:8. Compared with heterosexuals, the aOR for HCV seropositivity among MSM was 0.47 (95% CI, 0.31–0.72). Conclusions HCV seroprevalence among HIV-positive patients in Taiwan decreased with time, probably related to the inclusion of younger adults and more non-IDUs, and remained high among IDUs. HCV seropositivity was associated with age and an RPR titer ≥1:8 among patients who acquired HIV through sexual contact.

Abstract
Current guidelines recommend hepatitis C virus (HCV) testing for HIV-infected men who have sex with men (MSM) with ongoing risk behaviour, without specifying the type of risk behaviour. We developed and validated the HCV-MOSAIC risk score to assist HCV testing in HIV-infected MSM. The risk score consisted of six self-reported risk factors identified using multivariable logistic regression using data from the Dutch MOSAIC study (n = 213, 2009–2013). Area under the ROC curve (AUC), sensitivity, specificity, post-test-probability-of-disease and diagnostic gain were calculated. The risk score was validated in case–control studies from Belgium (n = 142, 2010–2013) and the United Kingdom (n = 190, 2003–2005) and in cross-sectional surveys at a Dutch sexually transmitted infections clinic (n = 284, 2007–2009). The AUC was 0.82; sensitivity 78.0% and specificity 78.6%. In the validation studies sensitivity ranged from 73.1% to 100% and specificity from 56.2% to 65.6%. The post-test-probability-of-disease ranged from 5.9% to 20.0% given acute HCV prevalence of 1.7% to 6.4%, yielding a diagnostic gain of 4.2% to 13.6%. The HCV-MOSAIC risk score can successfully identify HIV-infected MSM at risk for acute HCV infection. It could be a promising tool to improve HCV testing strategies in various settings.

Abstract
Alternative strategies are required to enhance the diagnosis of silent hepatitis C virus (HCV) infections in key populations at risk. Among them, HCV prevalence and bio-behavioural data are scarce for HIV-negative men who have sex with men (MSM) and men and trans-women sex workers. We sought to describe and assess the potential benefits of a community-based one-step HCV screening and confirmatory strategy for these populations in Barcelona. The screening strategy based on a real-time RT-PCR assay for HCV-RNA detection in dried-blood spots (DBS) was validated and implemented in addition to an antibody point-of-care test in a community centre. HCV prevalence was assessed, and bio-behavioural data were collected. The molecular assay was precise, reproducible, sensitive and specific. Four HIV-negative MSM reported being currently infected (0.75% HCV self-reported prevalence). Implementation of DBS testing was easy, and acceptability was >95%, but no silent HCV case was diagnosed (N = 580). High-risk sexual practices and drug use for sex were reported frequently. HIV prevalence was 4.7% in MSM and 10% in sex workers. Self-reported prevalence of other STIs ranged from 11.3% to 36.2%. In conclusion, HCV-RNA testing in DBS showed a good performance, but the assessed one-step strategy does not seem beneficial in this setting. Although no silent HCV infections were detected, the observed high-risk behaviours and prevalence of other STIs suggest that HCV spread should be periodically monitored among these populations in Barcelona by means of behavioural surveillance, rapid antibody testing and molecular confirmation in DBS.

Abstract
PURPOSE OF REVIEW Highly effective, well-tolerated interferon-free direct-acting antivirals (DAA) have revolutionised hepatitis C virus (HCV) therapeutics, with the opportunity for broad treatment scale-up among marginalised or "high-risk" populations, including people who inject drugs (PWID) and people with HIV/HCV coinfection. RECENT FINDINGS Concern that HCV reinfection may compromise HCV treatment outcomes is sometimes cited as a reason for not offering treatment to current and former PWID. However, the incidence of reinfection following interferon-based treatment for chronic HCV is low among PWID. Reinfection rates in HIV-positive men-who-have-sex-with-men (MSM) are varied, with high incidence reported in some cohorts. Mathematical modelling suggests that substantial reductions in HCV incidence and prevalence could be achieved with targeted DAA therapy among those at the highest risk of ongoing transmission. This review will summarise the recent literature on DAA efficacy in PWID and people with HIV/HCV coinfection, discuss the individual- and population-level impact of DAA treatment scale-up and reinfection, and highlight ongoing and future research questions in expanding HCV care and treatment to those populations at high risk of ongoing HCV transmission.

Abstract
OBJECTIVE MSM are at increased risk for infection with HIV-1 and hepatitis C virus (HCV). Is HIV/HCV coinfection confined to specific HIV transmission networks? DESIGN AND METHODS A HIV phylogenetic tree was constructed for 5038 HIV-1 subtype B polymerase (pol) sequences obtained from MSM in the AIDS therapy evaluation in the Netherlands cohort. We investigated the existence of HIV clusters with increased HCV prevalence, the HIV phylogenetic density (i.e. the number of potential HIV transmission partners) of HIV/HCV-coinfected MSM compared with HIV-infected MSM without HCV, and the overlap in HIV and HCV phylogenies using HCV nonstructural protein 5B sequences from 183 HIV-infected MSM with acute HCV infection. RESULTS Five hundred and sixty-three of 5038 (11.2%) HIV-infected MSM tested HCV positive. Phylogenetic analysis revealed 93 large HIV clusters (≥10 MSM), 370 small HIV clusters (2-9 MSM), and 867 singletons with a median HCV prevalence of 11.5, 11.6, and 9.3%, respectively. We identified six large HIV clusters with elevated HCV prevalence (range 23.5-46.2%). Median HIV phylogenetic densities for MSM with HCV (3, interquartile range 1-7) and without HCV (3, interquartile range 1-8) were similar. HCV phylogeny showed 12 MSM-specific HCV clusters (clustersize: 2-39 HCV sequences); 12.7% of HCV infections were part of the same HIV and HCV cluster. CONCLUSION We observed few HIV clusters with elevated HCV prevalence, no increase in the HIV phylogenetic density of HIV/HCV-coinfected MSM compared to HIV-infected MSM without HCV, and limited overlap between HIV and HCV phylogenies among HIV/HCV-coinfected MSM. Our data do not support the existence of MSM-specific sexual networks that fuel both the HIV and HCV epidemic.

Abstract
BACKGROUND & AIMS Hepatitis C virus (HCV) incidence among HIV-positive men who have sex with men (MSM) has increased since 2000, although there are regional differences. We aimed to 1) estimate trends in HCV incidence among HIV-positive MSM, 2) assess the association between incidence and geographical region, age and HIV-related measurements and, 3) assess temporal changes from HIV seroconversion to HCV infection. METHODS Data was used from MSM with well-estimated dates of HIV seroconversion from the CASCADE Collaboration (1990-2014). Smoothly varying trends in HCV incidence over time were allowed, using restricted cubic splines. The association of calendar year, age, CD4 count (lagged), HIV RNA (lagged), geographical region and HIV infection stage (recent vs. chronic) with HCV incidence were assessed using Poisson regression. RESULTS Of 5,941 MSM, 337 acquired HCV during follow-up. HCV incidence significantly increased from 0.7/1,000 person-years in 1990 to 18/1,000 person-years in 2014. Recent calendar years, younger age, recent HIV infection and higher HIV RNA levels were significantly associated with HCV incidence, while CD4 count was not. Trends differed by geographical region; while incidence appeared to have stabilized in Western Europe and remained stable in Southern Europe, it continued to increase in Northern Europe in recent years. Time from HIV to HCV infection significantly decreased over time (p<0.001). CONCLUSIONS HCV has continued to spread among HIV-positive MSM in recent years, but trends differ by geographical region. Interventions to decrease the risk of HCV acquisition and increase early diagnosis are warranted. LAY SUMMARY Hepatitis C virus infection continues to spread among HIV-positive men who have sex with men, especially among younger individuals. However, trends seem to differ by European region in recent years. Furthermore, men who have sex with men with a higher HIV RNA load were more likely to get infected with the hepatitis C virus. During recent HIV infection, MSM appear to be at higher risk of acquiring hepatitis C.

Abstract
Direct-acting antivirals for hepatitis C virus infection may revolutionize treatment among persons with substance use disorders. Despite persons with substance use disorders having the highest hepatitis C virus prevalence and incidence, the vast majority have not engaged into care for the infection. Previously, interferon-based treatments, with substantial side effects and the propensity to exacerbate mental health conditions, were major disincentives to pursuit of care for the infection. Direct-acting antivirals with viral eradication rates of >90%, significantly improved side effect profiles, and shorter treatment duration are dramatic improvements over prior treatment regimens that should promote widespread hepatitis C virus care among persons with substance use disorders. The major unmet need is strategies to promote persons with substance use disorders engagement into care for hepatitis C virus. Although physical integration of treatment for substance use and co-occurring conditions has been widely advocated, it has been difficult to achieve. Telemedicine offers an opportunity for virtual integration of behavioral and medical treatments that could be supplemented by conventional interventions such as hepatitis C virus education, case management, and peer navigation. Furthermore, harm reduction and strategies to reduce viral transmission are important to cease reinfection among persons with substance use disorders. Widespread prescription of therapy for hepatitis C virus infection to substance users will be required to achieve the ultimate goal of global virus elimination. Combinations of medical and behavioral interventions should be used to promote persons with substance use disorders engagement into and adherence with direct-acting antiviral-based treatment approaches. Ultimately, either physical or virtual colocation of hepatitis C virus and substance use treatment has the potential to improve adherence and consequently treatment efficacy.

Abstract
One challenge to HCV elimination through therapeutic intervention is reinfection. The aim of this analysis was to calculate the incidence of HCV reinfection among both HIV-positive and HIV-negative individuals treated for recent HCV infection (estimated infection duration <18 months). Individuals with recent HCV infection who achieved an end-of-treatment response in four open-label studies between 2004 and 2015 in Australia and New Zealand were assessed for HCV reinfection, confirmed by sequencing of the Core-E2 and/or NS5B regions. Reinfection incidence was calculated using person-time of observation. Exact Poisson regression analysis was used to assess factors associated with HCV reinfection. The cohort at risk for reinfection (n=120; 83% male; median age 36 years) was composed of HIV-positive men-who-have-sex-with-men (53%) and people who inject drugs (current 49%, ever 69%). Total follow-up time at risk was 135 person-years (median 1.08 years, range 0.17, 2.53). Ten cases of HCV reinfection were identified, for an incidence of 7.4 per 100 py (95% CI 4.0, 13.8). Reinfection incidence was significantly higher among participants who reported injection drug use at end of or post-treatment, irrespective of HIV status (15.5 per 100 py, 95% CI 7.8, 31.1). In adjusted analysis, factors associated with reinfection were older age (aIRR 5.3, 95% CI 1.15, 51.5, P=.042) and injection drug use at end of or post-treatment (aIRR 7.9, 95% CI 1.6, 77.2, P=.008). High reinfection incidence following treatment for recent HCV infection in individuals with ongoing risk behaviour emphasizes the need for post-treatment surveillance, harm reduction strategies and education in at-risk populations.

Abstract
PURPOSE OF REVIEW This review highlights key studies and recently published data, policies, and recommendations related to hepatitis C virus (HCV) epidemiology, transmission, and treatment. RECENT FINDINGS HCV is a leading cause of liver-related deaths, cirrhosis, and hepatocellular carcinoma. Since 2011 and accelerating since 2013, new, safe, tolerable, and curative therapies have considerably altered clinical and public health frameworks related to the prevention, control and clinical management of HCV. Nevertheless, there are several populations in the United States that are important to consider because of disparities in HCV prevalence and transmission risk. Adults born during 1945-1965 have an estimated anti-HCV antibody prevalence of ~3%, which is six times higher than among other adults, are often unaware of their infections, and are at increased risk of having HCV-associated morbidity and mortality from decades of chronic infection. Since the early 2000s, increasing incidence of acute HCV infections among young, white, non-urban people who inject drugs have been reported. Despite promising therapeutic advances, significant challenges remain for reducing HCV-associated morbidity and mortality. SUMMARY The high burden of HCV and significant health consequences associated with chronic infection make HCV a critical public health priority. Advances in HCV treatment have created new opportunities for reducing HCV-associated morbidity and mortality. These treatments are safe, well-tolerated, and highly effective; however, benefits cannot be realized without a significant increase in the number of persons tested for HCV so that all chronically infected individuals can be aware of their diagnosis and linked to appropriate clinical care.

Abstract
BACKGROUND Sexual transmission of Hepatitis C virus (HCV) in men who have sex with men (MSM) and its interaction with HIV status, sexually transmitted infections and sexual behaviour is poorly understood. We assessed the incidence and predictors of HCV infection in HIV positive MSM. METHODS The electronic medical record and laboratory results from HIV positive MSM in care at a large urban public specialist HIV clinic embedded in a sexual health centre in Melbourne Australia were collected. Patients with two or more HCV antibody tests between January 2008 and March 2016 and with no record of injecting drug use were included. The HCV exposure intervals were the periods between a negative HCV test and the next HCV test. We compared HCV exposure intervals temporally associated with and without newly acquired syphilis or anorectal chlamydia. HCV exposure intervals were also categorised as being before or after HIV virological suppression and by most recent and nadir CD4 cell count. RESULTS Thirty seven new HCV infections were diagnosed in 822 HIV positive MSM with no history of injecting drug use over 3114 person years (PY) of follow-up. Mean age was 43.1 years (±12.5) and mean CD4 cell count nadir was 362 cells/uL (±186). The incidence of HCV infection in the study population was 1.19/100PY (0.99-1.38). The incidence in exposure periods temporally close to new syphilis infection was 4.72/100PY (3.35-6.08) and to new anorectal chlamydia infection was 1.37/100PY (0.81-1.93). The incidence in men without supressed viral load was 3.19/100PY (1.89-4.49). In the multivariate Cox regression analysis only younger age (aHR 0.67 (0.48-0.92)), exposure periods temporally associated to new syphilis infection (aHR 4.96 (2.46-9.99)) and higher CD4 cell count nadir (aHR 1.26 per 100 cells/uL (1.01-1.58)) were associated with increased risk of HCV infection. During the study period the incidence of syphilis increased dramatically but the incidence of HCV infection remained the same. CONCLUSIONS Incidence of HCV infection is associated with syphilis but not anorectal chlamydia which suggests a biological rather than behavioural risk modification. Rising syphilis incidence may offset declines in HCV transmission through HCV treatment as prevention.

Abstract
Since 2000, an increase in hepatitis C virus infection among HIV-infected (HIV+) men who have sex with men has been observed. Evidence points to blood exposure during sex as the medium of hepatitis C virus transmission. Hepatitis C virus prevalence among HIV + MSM overall and in relation to injection drug use is poorly characterized. In this study, a systematic review and meta-analysis examining global hepatitis C virus antibody prevalence and estimating active hepatitis C virus prevalence among HIV + MSM were conducted; 42 reports provided anti-hepatitis C virus prevalence data among HIV + MSM. Pooled prevalence produced an overall anti-hepatitis C virus prevalence among HIV + MSM of 8.1%; active HCV prevalence estimate was 5.3%-7.3%. Anti-hepatitis C virus prevalence among injection drug use and non-injection drug use HIV + MSM was 40.0% and 6.7%, respectively. Among HIV + MSM, hepatitis C virus prevalence increased significantly over time among the overall and non-injection drug use groups, and decreased significantly among injection drug use HIV + MSM. We identified a moderate prevalence of hepatitis C virus among all HIV + MSM and among non-injection drug use HIV + MSM; for both, prevalence was observed to be increasing slightly. Pooled prevalence of hepatitis C virus among HIV + MSM was higher than that observed in the 1945-1965 US birth cohort. The modest but rising hepatitis C virus prevalence among HIV + MSM suggests an opportunity to control HCV among HIV + MSM; this combined with data demonstrating a rising hepatitis C virus incidence highlights the temporal urgency to do so.

Abstract
BACKGROUND For over a decade we have known of an epidemic of sexually transmitted hepatitis C virus (HCV) infection among human immunodeficiency virus (HIV)-infected men who have sex with men (MSM), but there still remains significant controversy over which bodily fluid(s) are responsible for HCV transmission in these men. METHODS We enrolled HIV-infected MSM with recent and chronic HCV infection and quantified HCV from rectal fluid obtained by blind swab. We compared the rectal HCV viral load (VL) with paired blood HCV VL. RESULTS We found rectal HCV shedding in 20 (47%) of 43 men, only one (2%) of whom had visible bleeding. Detection of rectal HCV shedding was associated with blood VL > 5 log10 IU/mL (p = .01), and 85% with blood VL > 5 log10 IU/mL had rectal shedding. The HCV VL of the rectal fluid ranged from 2.6 to 5.5 log10 IU/mL. Based on the median rectal fluid VL, the surface of an average human penis would be exposed to at least 2,300 IU of HCV for the duration of anal intercourse. CONCLUSION This study provides the first direct evidence to our knowledge that a sufficient quantity of HCV is shed into the rectum in HIV-infected men with HCV infection to directly infect an inserted penis or be passed indirectly through fomite-like transmission to the rectum of sex partner. We must develop an appropriate public health campaign to educate MSM about these routes of HCV infection to reverse the HCV epidemic among HIV-infected MSM.

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
Increasing incident HCV infections were found between 2011-2014 after declining between 2008-2010 among HIV-infected men in a Community Health Center in Baltimore. The reemerging epidemic was associated with sexual transmission and polydrug use among MSM with favorable socioeconomic status. Background. Sexual transmission of hepatitis C virus (HCV) among human immunodeficiency virus (HIV)-infected men who have sex with men (MSM) is an emerging issue. Studies addressing the temporal trends and risk factors associated with incident HCV in HIV-infected MSM in the community-based primary care settings in the United States are scarce. Methods. Using a retrospective cohort study design, HCV incidence, defined as HCV antibody seroconversion, was determined in 1147 HIV-infected men receiving care at Chase Brexton Health Care clinics in Baltimore, Maryland between 2004 and 2014. Multivariate regression analyses were used to identify factors associated with incident HCV. Results. There were 42 incident HCV infections during 5242 person-years (PY) of follow up (incidence rate [IR], 8.01/1000 PY). Thirty-seven (88%) of the incident infections were in MSM, of whom 31 (84%) reported no injection-drug use (IDU). The annual IRs for MSM were 13.1–15.8/1000 PY between 2004 and 2007, decreased to 2.7–6.2/1000 PY between 2008 and 2011, and increased to 10.4/1000 PY and 13.3/1000 PY in 2013 and 2014, respectively. Injection-drug use was strongly associated with incident HCV among all MSM (IR ratio [IRR], 14.15; P = .003); however, among MSM without IDU, entering care between 2010 and 2013 (IRR, 3.32; P = .01), being employed (IRR, 3.14; P = .03), and having a history of ulcerative sexually transmitted infections (IRR, 3.70; P = .009) or of polydrug use (IRR, 5.54; P = .01) independently predicted incident HCV. Conclusions. In this cohort of HIV-infected men, a re-emerging HCV epidemic was observed from 2011 to 2014 among MSM. In addition to IDU, high-risk sexual behaviors, favorable socioeconomic status, and polydrug use fueled this increase in HCV infections.

Abstract
Hepatitis C virus (HCV) is not considered to be efficiently transmitted sexually, but since the early 2000s, HCV infection of HIV-infected men who have sex with men has emerged as an epidemic worldwide. In this review, we discuss the epidemiology of sexually transmitted acute HCV, the growing body of literature regarding risk factors for acquisition, and possible mechanisms of transmission. We also discuss the progression of liver disease in these men and the advances in therapy of acute HCV with interferon-free regimens and put forth our current approach of evaluating and treating these men in New York City.

Abstract
Chronic hepatitis C (CHC) remains a public health issue affecting an estimated 220,000 individuals in Canada. In 2011, approximately 44% of those with CHC were unaware of their infection. Hepatitis C is infectious in origin, and if left untreated, can lead to significant morbidity and mortality in its chronic form, including liver cirrhosis, hepatocellular carcinoma and liver failure. These health outcomes are associated with comorbidities, adding a burden to the Canadian health care system. Recent advancements in the treatment of hepatitis C have changed the clinical landscape. In Canada, the prevalence of incident cases is higher in specific population groups. Injection drug use (IDU) currently accounts for the highest proportion of new hepatitis C virus (HCV) infection. It is unclear to what extent HCV infection through health care or personal services use contributed to current prevalent cases of CHC. The Canadian Task Force on Preventive Health Care (CTFPHC) is currently reviewing the evidence for different approaches to HCV screening and the benefits and harms of screening. Risk-based screening remains critical to detecting hepatitis C as knowing one's status has been linked to the cascade of care and improved population health outcomes. This article intends to highlight risk factors associated with the acquisition of HCV so that health care providers can screen, where appropriate, and detect CHC.

Abstract
Objectives Men who have sex with men (MSM) are at higher risk for coinfection with hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis than the general population. HIV infection and these coinfections accelerate disease progression reciprocally. This study evaluated the prevalence and incidence of these coinfections in HIV1-positive MSM in Germany. Materials and Methods As part of a nationwide, multicenter, prospective cohort study of HIV-infected MSM, plasma samples collected yearly were screened for HBsAg and antibodies to HBc, HBs, HCV, and syphilis. Samples with indications of active HBV or HCV infection were confirmed by polymerase chain reaction. Prevalence and incidence of each infection and incidence rates per study participant were calculated, and incidences over 4-year time intervals compared. Results This study screened 5,445 samples from 1,843 MSM. Median age at HIV seroconversion was 33 years. Prevalences of active, cleared, and occult HBV, and of active/cleared HCV were 1.7%, 27.1%, 0.2%, and 8.2%, respectively, and 47.5% had been effectively vaccinated against HBV. Prevalence of antibodies to Treponema pallidum and of triple or quadruple sexually transmitted infections (STIs) were 39.6% and 18.9%, respectively. Prevalence of STI, cleared HBV, HBV vaccination, and history of syphilis differed significantly among age groups. Incidences of HBV, HCV, and syphilis were 2.51, 1.54, and 4.06 per 100 person-years, respectively. Incidences of HCV and syphilis increased over time. HCV incidence was significantly higher in MSM coinfected with syphilis and living in Berlin, and syphilis incidence was significantly higher for MSM living in Berlin. Discussion Despite extensive HBV vaccination campaigns, fewer than 50% of screened MSM were effectively vaccinated, with a high proportion of HIV-positive MSM coinfected with HBV. High rates of STI coinfections in HIV-positive MSM and increasing incidences emphasize the need for better tailored campaigns for HBV vaccination and STI prevention.
