Abstract
BACKGROUND Gay and bisexual men (GBM) are a key population affected by HIV and hepatitis C (HCV) co-infection. Providing HCV treatment scale-up across specialist and non-hepatitis specialist settings may eliminate HCV in this population. We aimed to (1) deliver and measure HCV treatment effectiveness, and (2) determine the population impact of treatment on HCV prevalence and incidence longitudinally. METHODS The co-EC Study (Enhancing care and treatment among HCV/HIV co-infected individuals to Eliminate Hepatitis C transmission) was an implementation trial providing HCV direct-acting antiviral treatment in Melbourne, Australia, from 2016-2018. Individuals with HCV/HIV co-infection were prospectively enrolled from primary and tertiary-care services providing care for 85% of GBM with HIV in our jurisdiction. HCV-viraemic prevalence and HCV-antibody/viraemic incidence were measured using a state-wide, individually-linked, electronic surveillance system. RESULTS Among 200 participants recruited, 186 initiated treatment during the study period. Sustained virological response among primary care participants (98%, 95%CI:93-100%) was not different to tertiary care (98%, 95%CI:86-100%). From 2012-2019, between 2434 and 3476 GBM with HIV-infection attended our primary-care sites annually providing 13,801 person-years of follow-up; 50-60% received an HCV test annually, 10-14% were anti-HCV positive. Among those anti-HCV positive, viraemic prevalence declined 83% during the study (54% to 9%; 2016 to 2019). HCV incidence decreased 25% annually from 1.7/100 person-years in 2012 to 0.5/100 person-years in 2019 (incidence rate ratio 0.75; CI:0.68-0.83;p<0.001). CONCLUSION High treatment effectiveness by non-specialists demonstrates the feasibility of treatment scale-up in this population. Substantial declines in HCV incidence and prevalence among GBM with HIV-infection provides proof-of-concept for HCV micro-elimination. REGISTRATION ClinicalTrials.gov (Identifier: NCT02786758).

Abstract
OBJECTIVES Australian guidelines recommend annual testing for HIV and sexually transmitted infections (STIs) for all men who have sex with men (MSM) and 3-6 monthly testing for those at higher risk as defined by behavioural criteria. We assessed HIV/STI re-testing rates among MSM attending primary care clinics. METHODS We conducted a retrospective follow-up of HIV negative MSM tested for HIV or STIs (chlamydia or syphilis) at four primary care clinics in the 9-month period: April to December 2006. Re-testing rates for these infections were calculated over 18 months. Logistic regression was undertaken to identify predictors of guideline adherence. RESULTS Of the MSM requiring annual HIV testing according to the guidelines, the re-testing rates at 1 y were 35% (762/2163). Among the higher risk MSM, 6-monthly HIV re-testing rates were 15% (283/1862). Within the subgroup who reported 11 or more male sexual partners within the past 6 months, HIV re-testing rates within 6 months were 19%. Independent predictors of HIV re-testing within 6 months in higher-risk MSM were reporting 11 or more male sexual partners in the last 6 months (AOR 3.1, 95% CI 1.8 to 4.8); being born overseas (AOR 2.0, 95% CI 1.2 to 3.4); and previous HIV testing more than 12 months earlier (AOR 3.3, 95% CI 1.9 to 5.5). CONCLUSION There is poor adherence to national guidelines that recommend regular re-testing of MSM for STIs, particularly among those at higher risk who require more frequent testing. Clinical strategies are urgently needed to encourage more frequent HIV/STI testing among MSM, especially in the higher risk subgroup.
