Chems4EU: chemsex use and its impacts across four European countries in HIV‐positive men who have sex with men attending HIV services

Introduction: Chemsex in a European context is the use of any of the following drugs to facilitate sex: crystal methamphetamine, mephedrone and gamma-hydroxybutyrate (GHB)/gamma-butyrolactone (GBL) and, to a lesser extent, cocaine and ketamine. This study describes the prevalence of self-reported recreational drug use and chemsex in HIV-positive men who have sex with men (MSM) accessing HIV services in four countries. It also examines the problematic impacts and harms of chemsex and access to chemsex-related services. Methods: This is a cross-sectional multi-centre questionnaire study of HIV-positive MSM accessing nine HIV services in the UK, Spain, Greece and Italy. Results: In all, 1589 HIV-positive MSM attending HIV services in four countries completed the questionnaire. The median age of participants was 38 years (interquartile range: 32-46 years) and 1525 (96.0%) were taking antiretroviral therapy (ART). In the previous 12 months, 709 (44.6%) had used recreational drugs, 382 (24.0%) reported chemsex and 104 (6.5%) reported injection of chemsex-associated drugs ('slamsex'). Of the 382 engaging in chemsex, 155 (40.6%) reported unwanted side effects as a result of chemsex and 81 (21.2%) as a result of withdrawal from chemsex. The reported negative impacts from chemsex were on work (25.1%, 96), friends/family (24.3%, 93) and relationships (28.3%, 108). Fifty-seven (14.9%) accessed chemsex-related services in the past year, 38 of whom (67%) felt the service met their needs. Discussion: A quarter of participants self-reported chemsex in the past 12 months. There were high rates of harms from chemsex across all countries, including negative impacts on work, friends/family and relationships. Although a minority of those engaging in chemsex accessed support, most found this useful

Immunogenicity and Safety of BNT162b2 Homologous Booster Vaccination in People Living with HIV under Effective cART

Data on COVID-19 boosting vaccination in people living with HIV (PLWH) are scant. We investigated the immunogenicity and safety of the BNT162b2 homologous boosting vaccination. Anti-SARS-CoV-2 spike antibodies (LIAISON® SARS-CoV-2 S1/S2 IgG test, DiaSorin®), CD4+, CD8+ and viraemia were monitored at T0 (pre-vaccination), T1 (4 weeks after the second dose), T2 (pre-booster) and T3 (4 weeks after the booster dose). Humoral responses were evaluated according to sex, age, BMI, nadir and baseline CD4+ counts, as well as type of cART regimen. Forty-two subjects were included: the median age was 53 years (IQR: 48–61); the median time since HIV was 12.4 years (IQR: 6.5–18.3); the median nadir and baseline CD4+ counts were 165 (IQR: 104–291) and 687 cells/mm3 (IQR: 488–929), respectively. The booster dose was administered at a median of 5.5 months after the second dose. Median anti-SARS-CoV-2 IgG concentration had significantly decreased at T2 compared to T1 (107 vs. 377, p < 0.0001). Antibody levels elicited by the booster dose (median: 1580 AU/mL) were significantly higher compared with those of all the other time points (p < 0.0001). None of the investigated variables significantly affected antibody response induced by the booster dose. Local and systemic side-effects were referred by 23.8% and 14.3% of the subjects, respectively. One patient developed sensorineural hearing loss (SNHL) 24 h after boosting. He recovered auditory function upon endothympanic administration of corticosteroids. The BNT162b2 boosting vaccination in PLWH is safe and greatly increased the immune response with respect to the primary vaccination

Uptake and discontinuation of integrase inhibitors (INSTIs) in a large cohort setting.

BACKGROUND Despite increased INSTI use, limited large-scale, real-life data exists on INSTI uptake and discontinuation. SETTING International multicohort collaboration. METHODS RESPOND participants starting dolutegravir (DTG), elvitegravir (EVG) or raltegravir (RAL) after 1/1/2012 were included. Predictors of INSTI used were assessed using multinomial logistic regression. Kaplan Meier and Cox proportional hazards models describe time to and factors associated with discontinuation. RESULTS Overall, 9702 persons were included; 5051 (52.1%) starting DTG, 1933 (19.9%) EVG, 2718 (28.0%) RAL. The likelihood of starting RAL or EVG versus DTG decreased over time and was higher in Eastern and Southern Europe compared to Western Europe.At 6 months after initiation, 8.9% (95% CI 8.3%-9.5%) had discontinued the INSTI (6.4% DTG, 7.4% EVG, 14.0% RAL). The main reason for discontinuation was toxicity (44.2% DTG, 42.5% EVG, 17.3% RAL). Nervous system toxicity accounted for a higher proportion of toxicity discontinuations on DTG (31.8% DTG, 23.4% EVG, 6.6% RAL). Overall, treatment simplification was highest on RAL (2.7% DTG, 1.6% EVG, 19.8% RAL).Factors associated with a higher discontinuation risk included increasing year of INSTI initiation, female gender, hepatitis C coinfection, and prior non-AIDS defining malignancies. Individuals in Southern and Eastern Europe were less likely to discontinue. Similar results were seen for discontinuations after 6 months. CONCLUSION Uptake of DTG versus EVG or RAL increased over time. Discontinuation within 6 months was mainly due to toxicity; nervous system toxicity was highest on DTG. Discontinuation was highest on RAL, mainly due to treatment simplification
