The Contribution of Homelessness to Opioid Overdose Mortality and Associated Racial Disparities
Interest in Long-Acting PrEP by Methamphetamine Use Among Men Who Have Sex with Men in Four Western US Cities
Methamphetamine use is a driver of HIV among men who have sex with men (MSM) and is associated with suboptimal adherence to daily, oral PrEP. Long-acting PrEP may be a promising alternative. We analyzed data from the 2023 National HIV Behavioral Surveillance survey in four western cities to assess interest in long-acting PrEP among HIV-negative MSM participants. Of 1,450 participants, 7% used methamphetamine in the past 12 months. Two-thirds were…

HIV sero disclosure among men who have sex with men and transgender women on HIV pre-exposure prophylaxis
HIV pre-exposure prophyalxis (PrEP) might lead individuals to view serodisclosure as unnecessary. We examined the prevalence of non-disclosure and lack of knowledge of partner status in a global cohort of men who have sex with men (MSM) and transgender women (TW) enrolled in the iPrEx Open Label Extension (OLE). We calculated prevalence ratios by fitting a logistic model and estimating predicted probabilities using marginal standardization. Preva…
The Role of Social Relationships in PrEP Uptake and Use Among Transgender Women and Men Who Have Sex with Men
The Impact of HIV Pre-exposure Prophylaxis (PrEP) Use on the Sexual Health of Men Who Have Sex with Men
This study explores the impacts of HIV pre-exposure prophylaxis (PrEP) use on the sexual health of men who have sex with men (MSM). The authors conducted in-depth interviews with MSM who use PrEP (n = 14). Data was analyzed using interpretative phenomenological analysis. PrEP use reduced fear and shame associated with sex and facilitated greater sexual satisfaction and intimacy. Although participants generally viewed PrEP as empowering and benefi…
Risk, safety and sex among male PrEP users
Recent advances in biomedical HIV prevention have led to optimistic projections of a dramatic worldwide reduction of new infections by 2030. This optimism is counterbalanced by concerns that the protective benefits of one such technology, HIV pre-exposure prophylaxis (PrEP), may be negated by increases in other behaviours that offset these benefits (risk compensation). To contribute to a deeper understanding of concepts of safety and risk in the …
Self-reported Recent PrEP Dosing and Drug Detection in an Open Label PrEP Study
Monitoring adherence to pre-exposure prophylaxis (PrEP) is part of the recommended package for PrEP prescribing, yet ongoing concerns about how to do so confidently are exacerbated by gross discrepancies in reported and actual use in clinical trials. We evaluated concordance between reports of recent PrEP dosing collected via neutral interviewing and drug quantitation in the iPrEx open-label extension, where participants (n = 1172) had the choice…
The Effect of Depressive Symptoms on Adherence to Daily Oral PrEP in Men who have Sex with Men and Transgender Women
HIV pre-exposure prophylaxis in transgender women
Acceptability of drug detection monitoring among participants in an open-label pre-exposure prophylaxis study
In the world of HIV pre-exposure prophylaxis (PrEP) research, there is emerging interest in providing study participants with pharmacokinetic results from drug level testing to guide adherence counseling. The iPrEx randomized control trial was the first study to produce meaningful results of PrEP in humans. In the iPrEx open-label extension (OLE) study, blood plasma samples collected in the first 12 weeks of study participation were tested for th…
Depression and Oral FTC/TDF Pre-exposure Prophylaxis (PrEP) Among Men and Transgender Women Who Have Sex With Men (MSM/TGW)
We conducted a longitudinal and cross-sectional analysis of depressive symptomology in iPrEx, a randomized, placebo-controlled trial of daily, oral FTC/TDF HIV pre-exposure prophylaxis (PrEP) in men and transgender women who have sex with men. Depression-related adverse events (AEs) were the most frequently reported severe or life-threatening AEs and were not associated with being randomized to the FTC/TDF arm (152 vs. 144 respectively OR 0.66 95…

Preexposure Chemoprophylaxis for HIV Prevention in Men Who Have Sex with Men
BACKGROUND: Antiretroviral chemoprophylaxis before exposure is a promising approach for the prevention of human immunodeficiency virus (HIV) acquisition. METHODS: We randomly assigned 2499 HIV-seronegative men or transgender women who have sex with men to receive a combination of two oral antiretroviral drugs, emtricitabine and tenofovir disoproxil fumarate (FTC-TDF), or placebo once daily. All subjects received HIV testing, risk-reduction counse…
