BACKGROUND: Sexual transmission of hepatitis C virus (HCV) is uncommon, yet documented among men who have sex with men (MSM), primarily among those with HIV. METHODS: In HPTN 078, which assessed an integrated strategy to achieve HIV viral suppression, 1305 MSM were screened across four geographically diverse US cities. At screening, demographic/behavioral/psychosocial questionnaires were completed, along with HIV and HCV testing. Multivariable logistic regression was used to evaluate associations with HCV antibody positivity. RESULTS: Of the 1287 (99%) MSM with HCV antibody results, median age was 41, 69% were Black, 85% had a high school diploma or more, 35% were employed, 70% had HIV, and 21% had undergone substance use counseling. The median lifetime number of male sexual partners was 17 (IQR: 6, 50) and 246 (19%) were HCV antibody positive. HCV antibody positivity was high in MSM with HIV (20%) and MSM without HIV (17%) (P=0.12) and was higher in those receiving substance use counseling (36%) than those that had not (15%)(P=<0.01). Substance use counseling [OR 2.51, 95% CI 1.80-3.51] and unstable housing [OR 2.16, 95% CI 1.40-3.33] were associated with HCV antibody positivity. CONCLUSION: Nearly 1 in 5 MSM screened for HPTN 078 have been infected with HCV. The prevalence is high regardless of HIV status and is high even in those who did not undergo substance use counseling. In HIV burden networks, high HCV infection prevalence may occur in MSM without HIV. As PrEP implementation expands and condom use declines, routine HCV counseling and screening among MSM is important.
