Early adopters of doxycycline as post-exposure prophylaxis to prevent bacterial sexually transmitted infections in a real-world clinical setting.

OBJECTIVES: Doxycycline as post-exposure prophylaxis (DoxyPEP) is a novel prevention approach which has demonstrated efficacy in preventing bacterial sexually transmitted infections (STIs) in men who have sex with men (MSM) and transgender women (TGW) including people who are living with HIV and those on HIV pre-exposure prophylaxis (PrEP). We evaluated patient knowledge and interest in DoxyPEP, as well as early adopters of its use. METHODS: In 2023, patients presenting for HIV and STI services at a primary care and sexual health clinic were asked about DoxyPEP knowledge, interest and use. Bivariate and multivariate analyses were used to evaluate demographics and behaviours associated with these outcomes. RESULTS: A total of n=421 people presented for care. Of these, 314 were MSM/TGW. Fifteen percent were Black/African-American, and 21% were Hispanic/Latino. A total of 50% of MSM/TGW had heard of DoxyPEP, 49% were interested and 18% reported prior DoxyPEP use. Having a history of STI infection ever (adjusted OR (aOR) 5.95, 95% CI 2.69 to 13.13) and in the past 12 months (aOR 2.99, 95% CI 1.56 to 5.72) were both associated with DoxyPEP use. Individuals who had ever used HIV PrEP had nearly three times the odds of ever taking DoxyPEP (aOR 2.88, 95% CI 1.56 to 5.30). There was no association between the use of DoxyPEP and race, ethnicity or HIV status. CONCLUSIONS: Among MSM and TGW, there is already significant awareness, interest and use of DoxyPEP to prevent bacterial STIs. Public health efforts should focus on improving access and delivery of this STI prevention intervention to MSM and TGW.

Perspectives of a peer-driven approach to improve pre-exposure prophylaxis and HIV prevention among Black/African American and Hispanic/Latino men who have sex with men.

BACKGROUND: Black/African American (B/AA) and Hispanic/Latino (H/L) men who have sex with men (MSM) are significantly less likely than white MSM to initiate pre-exposure prophylaxis (PrEP). A peer-driven intervention (PDI) may be an effective approach to addressing this disparity. In this study, we explored community member perspectives of a PDI to promote PrEP uptake among B/AA and H/L MSM. METHODS: We conducted semi-structured interviews with B/AA and H/L HIV-negative MSM between August 2018 and October 2019 in Rhode Island, USA. Participants reported their perspectives and recommendations for a PDI. Data from participant responses were thematically analysed. RESULTS: Of 15 MSM, the median age was 25years (interquartile range: 22, 33). The majority identified as B/AA (53.3%), H/L (66.7%), and having a college education or above (53.3%). Most participants viewed a PDI positively and were willing to learn and promote PrEP among their peers. Participants identified and supported several potential intervention components, such as education about the benefit of PrEP, emphasising prevention-effective dosing, and clarifying no prevention effect towards other sexually transmitted infections. They preferred in-person meetings to electronic communication. Preferred characteristics of peer educators included compassion, good communication skills, and enthusiasm about PrEP. CONCLUSIONS: This in-depth qualitative interview suggested that a PDI approach is promising in promoting PrEP uptake, as it could deliver culturally appropriate education and encourage PrEP uptake via peer influence among B/AA and H/L MSM.
