Background: In Australia, the incidence of hepatitis C virus (HCV) has declined among gay and bisexual men (GBM) with human immunodeficiency virus (HIV) since 2015 and is low among GBM using HIV preexposure prophylaxis (PrEP). However, ongoing HCV testing and treatment remains necessary to sustain this. To assess the potential utility of sexually transmissible infections (STIs) to inform HCV testing among GBM with HIV and GBM using PrEP, we examined the association between bacterial STI diagnoses and subsequent primary HCV infection.

Methods: Data were from a national network of 46 clinics participating in the Australian Collaboration for Coordinated Enhanced Sentinel Surveillance. GBM included had ≥1 HCV antibody negative test result and ≥1 subsequent HCV antibody and/or RNA test. Discrete time survival analysis was used to estimate the association between a positive syphilis, rectal chlamydia, and rectal gonorrhea diagnosis in the previous 2 years and a primary HCV diagnosis, defined as a positive HCV antibody or RNA test result.

Results: Among 6529 GBM with HIV, 92 (1.4%) had an incident HCV infection. A prior positive syphilis diagnosis was associated with an incident HCV diagnosis (adjusted hazard ratio, 1.99 [95% confidence interval, 1.11-3.58]). Among 13 061 GBM prescribed PrEP, 48 (0.4%) had an incident HCV diagnosis. Prior rectal chlamydia (adjusted hazard ratio, 2.75 [95% confidence interval, 1.42-5.32]) and rectal gonorrhea (2.54 [1.28-5.05]) diagnoses were associated with incident HCV.

Conclusions: Diagnoses of bacterial STIs in the past 2 years was associated with HCV incidence. These findings suggest that STIs might be useful for informing HCV testing decisions and guidelines for GBM with HIV and GBM using PrEP.

Purpose: Intimate partner violence (IPV) victimization is a pressing issue among men who have sex with men (MSM) and has profound health implications. This study aims to estimate the prevalence of IPV and identify factors associated with its occurrence among MSM in Hanoi, Vietnam.

Methods: A cross-sectional study was conducted from March to May 2023 at an MSM-friendly sexual health clinic in Hanoi.

Previous work has demonstrated that gay, bisexual men, and other men who have sex with men (GBM) living with HIV are likely to experience intersectional stigma. However, mainstream systems often fail to recognize how power and privilege shape this experience. Such a complex psychological phenomenon requires an in-depth reflective inquiry that acknowledges individuals as experts in their own experiences.

Introduction: Populations at risk for HIV infection-including gay, bisexual, and other men who have sex with men (GBM) and transgender/gender diverse people (TGD)-are at disproportionate risk for anal cancer. Most anal cancers are caused by human papillomavirus (HPV) and are preventable with HPV vaccination and screening. Engaging at-risk populations who are already receiving HIV preventive care (eg, pre-exposure prophylaxis [PrEP]) may be an effective implementation strategy.

Heterosexuals have become the most prevalent group of HIV-1 in Kunming, Yunnan Province. Utilizing the principle of genetic similarity between their gene sequences, we built a molecular transmission network by gathering data from earlier molecular epidemiological studies. This allowed us to analyze the epidemiological features of this group and offer fresh concepts and approaches for the prevention and management of HIV-1 epidemics.

The 2022 mpox epidemic predominantly affected gay, bisexual, and other men who have sex with men (GBM). Led by a provincial community program and co-galvanized by clinician-researchers, GBM community leaders in Ontario coordinated a robust response, representing a reproducible strategy for community engagement and mobilization during future epidemics.
