ABSTRACT
BACKGROUND: Antiretroviral therapy (ART)-related weight gain is of particular concern in people with HIV (PWH). While weight gain was observed among PWH receiving tenofovir alafenamide (TAF), little is known about the potential reversibility after TAF discontinuation. We evaluated weight and metabolic changes 12 months after TAF discontinuation in the Swiss HIV Cohort Study. METHODS: We included participants who received at least six months of TAF-containing ART between January 2016 and March 2023. Using multivariable mixed-effect models, changes in weight and lipid levels were compared between individuals who continued TAF and those who switched to one of the following TAF-free regimens: TDF-based ART, dolutegravir/lamivudine (DTG/3TC), or long-acting cabotegravir/rilpivirine (CAB/RPV). RESULTS: Of 6555 participants (median age 54 years, 24.3% female, 13% Black), 5485 (83.7%) continued and 1070 (16.3%) stopped TAF. Overall, discontinuing TAF was associated with an adjusted mean weight change of -0.54 kg (95% CI -0.98 to -0.11) after 12 months. In stratified analyses, switching from TAF to TDF led to an adjusted mean weight decrease of -1.84 kg (CI -2.72 to -0.97), and to a decrease in mean total cholesterol (-0.44 mmol/L) and triglycerides (-0.38 mmol/L) after 12 months. Switching from TAF-based ART to DTG/3TC (-0.17 kg, CI -0.82 to 0.48) or long-acting CAB/RPV (-0.64 kg, CI -2.16 to 0.89) did not lead to reductions in weight. CONCLUSIONS: Replacing TAF with TDF in PWH led to a decrease in body weight and an improved lipid profile within one year. Weight changes were not observed among individuals who switched to DTG/3TC or long-acting CAB/RPV.
ABSTRACT
Chemsex, a specific form of sexualized drug use (SDU), has rapidly increased in the last decade. This phenomenon could result in a complex public health issue because of the heterogeneity amongst socio-psychological profiles of the practitioners, leading to the difficulty to target specific populations. Healthcare professionals need to be aware of this practice and its related risks to provide care adapted to the individual who consults. Here, we suggest that better knowledge of this field can help to improve prevention measures and provide information with a non-judgmental and respectful approach to those who practice chemsex.

In 2015, the publication of important studies allowed the development of new guidelines, notably by WHO and the European AIDS ClinicalSociety (EACS), for HIV preventive treatment (pre-exposure prophylaxis), as well as for the start of antiretroviral treatment. The START and TEMPRANO studies have extended the treatment to all HIV-infected patients, irrespective of the level of immunosuppression and therefore the CD4 count. In addition, innovative screening methods, such as self-tests, are now available in all French pharmacies since 15 September 2015. The latest developments in 2015 concerning the prevention, screening, and treatment of HIV are discussed in this article and will certainly have an impact on the care of patients in Switzerland.
