The article presents guidelines given by the British HIV Association (BHIVA) on best clinical practice for antiretroviral therapy (ART) and management of adults living with human immunodeficiency virus (HIV). Topics discussed include involvement of people living with HIV, primary aim of ART, and considerations when managing people with spontaneous HIV viral control.

Objectives: Chemsex has been reported among men who have sex with men (MSM) living with HIV. There have been concerns about potentially harmful drug–drug interactions between chemsex drugs and antiretroviral therapy (ritonavir and cobicistat). We aimed to describe the prevalence and patterns of chemsex users in our HIV clinic population and to evaluate antiretroviral prescribing among chemsex users. Methods: We undertook a cross‐sectional study of patients attending our HIV clinic between January 2019 and December 2020. We collected data on patients who disclosed recent recreational drug use including chemsex in the previous 3 months. Results: In all, 2202/2501 (88%) patients were asked about recreational drug use and 514 (23%) disclosed recreational drug use. Eighty‐two (4%) of these disclosed recent chemsex; 73 (89%) used crystal methamphetamine, 51 (62%) used gamma‐hydroxybutyrate (GHB)/gamma‐butyrolactone (GBL), 55 (67%) reported poly‐drug use and 63 (76%) reported injecting drug use. The chemsex users were all cis‐male MSM and were significantly older (53 vs. 46 years, p < 0.0001), and more likely to have had previous syphilis (73% vs. 28%, p < 0.0001) than patients reporting non‐chemsex drug use. All chemsex users were prescribed antiretrovirals and 74 (90%) had an undetectable HIV viral load; 31 (38%) patients were taking either ritonavir (N = 12) or cobicistat (N = 19) as part of their antiretroviral regimen and this was similar to other patients attending for HIV care [31/82 (38%) vs. 768/2419 (31%), p = 0.25]. Conclusions: The prevalence of chemsex users among our HIV clinic attendants is 4%, and 38% of these were prescribed either ritonavir or cobicistat. Chemsex use should be a factor in antiretroviral therapy decision‐making to avoid potential harm. [ABSTRACT FROM AUTHOR]

The article offers information on the guidelines from the British HIV Association concerning the use of antiretroviral therapy for the treatment of adults with HIV-1 positive in 2015. Topics discussed include the areas of treatment and care identified by the guidelines, the factors affecting the outcomes of treatment and adverse effects, and the direct impact of the socio-economic status of an individual on adherence.

The article discusses the British HIV Association guidelines for the treatment of HIV-1-positive adults with antiretroviral therapy (HAART) 2012. It includes guidance on initiation of ART in those previously naive to therapy; support of patients on treatment; management of patients experiencing virological failure; and recommendations in specific patient populations. They are aimed at clinical professionals directly involved with the care of adults with HIV infection and at community advocates.
