Article Synopsis
  • Doxycycline postexposure prophylaxis (doxyPEP) effectively reduces the incidence of bacterial sexually transmitted infections (STIs) in those assigned male at birth, although practical data is limited.
  • This study analyzed electronic health records of HIV PrEP users from Kaiser Permanente Northern California to assess the uptake of doxyPEP and its impact on STI rates before and after its initiation.
  • Out of 11,551 HIV PrEP users, 19.5% received doxyPEP, with a notable percentage having an STI prior; findings suggest changes in STI positivity rates among those who started doxyPEP versus those who did not.

Background: The effect of initial antiretroviral therapy (ART) class on cancer risk in people with HIV (PWH) remains unclear.

Setting: Cohort study of 36,322 PWH enrolled (1996-2014) in the North American AIDS Cohort Collaboration on Research and Design.

Methods: We followed individuals from ART initiation (protease inhibitor [PI]-, non-nucleoside reverse transcriptase inhibitor [NNRTI]-, or integrase strand transfer inhibitor [INSTI]-based) until incident cancer, death, loss-to-follow-up, 12/31/2014, 85 months (intention-to-treat analyses [ITT]), or 30 months (per-protocol [PP] analyses).

Background: With extended lifespans for people with human immunodeficiency virus (PWH), there is a corresponding increased burden of chronic illnesses, including cancer. Our objective was to estimate the excess mortality among PWH with cancer compared with people without HIV (PWoH), accounting for the higher background mortality in the general PWH population.

Methods: We identified 39,000 PWH and 387,767 demographically matched PWoH in three integrated healthcare systems from 2000 to 2016.

Objective: To compare the model-predicted benefits, harms, and cost-effectiveness of cytology, cotesting, and primary HPV screening in US women with HIV (WWH).

Design: We adapted a previously published Markov decision model to simulate a cohort of US WWH.

Setting: United States.

Persons with HIV (PWH) experience high levels of pain. We examined the relationship of pain severity with use of cannabis and prescription opioids among PWH. This cross-sectional study evaluated associations between self-reported pain (moderate/severe vs mild/none) and cannabis and prescription opioid use in a primary care sample of PWH enrolled in an alcohol use treatment study at Kaiser Permanente, San Francisco.
