RESUMO
BACKGROUND: Male hypogonadism is not uncommon in people with HIV (PWH), with estimated prevalence ranging from 9% to 16%. Existing data are limited on the serum testosterone levels in PWH in Asian populations. METHODS: We enrolled HIV-positive men who have sex with men (MSM) and had been on stable antiretroviral therapy and MSM without HIV between February 2021 and November 2022. Serum free testosterone levels, sex hormone-binding globulins and other associated hormones were measured. Multiple linear regression analysis was performed to assess the association between serum free testosterone levels and clinical variables collected. RESULTS: A total of 447 MSM with HIV and 124 MSM without HIV were enrolled. Compared with MSM without HIV, MSM with HIV had a higher age (median, 41 versus 29.5 years) and prevalence of symptomatic hypogonadism (8.3% versus 1.6%). Among MSM who were aged <35 years, there were no significant differences in the serum free testosterone levels and prevalences of hypogonadism between the two groups. In multiple linear regression analysis, serum free testosterone level significantly decreased with advanced age (a decrease of 1.14 pg/mL per 1-year increase) and a higher body-mass index (BMI) (a decrease of 1.07 pg/mL per 1-kg/m2 increase), but was not associated with HIV serostatus. CONCLUSION: We found that MSM with HIV had a higher prevalence of symptomatic hypogonadism than MSM without HIV in Taiwan, which could be attributed to age difference. Serum free testosterone levels were negatively correlated with age and BMI, but did not show a significant correlation with HIV serostatus.
RESUMO
BACKGROUND: Real-world vaccine effectiveness following the third dose of vaccination against SARS-CoV-2 remains less investigated among people with HIV (PWH). METHODS: PWH receiving the third dose of BNT162b2 and mRNA-1273 (either 50- or 100-µg) were enrolled. Participants were followed for 180 days until the fourth dose of COVID-19 vaccination, SARS-CoV-2 infection, seroconversion of anti-nucleocapsid IgG, death, or loss to follow-up. Anti-spike IgG was determined every 1-3 months. RESULTS: Of 1427 participants undergoing the third-dose COVID-19 vaccination, 632 (44.3%) received 100-µg mRNA-1273, 467 (32.8%) 50-µg mRNA-1273, and 328 (23.0%) BNT162b2 vaccine and the respective rate of SARS-CoV-2 infection or seroconversion of anti-nucleocapsid IgG was 246.1, 280.8 and 245.2 per 1000 person-months of follow-up (log-rank test, p = 0.28). Factors associated with achieving anti-S IgG titers >1047 BAU/mL included CD4 count <200 cells/mm3 (adjusted odds ratio [aOR], 0.11; 95% CI, 0.04-0.31), plasma HIV RNA >200 copies/mL (aOR, 0.27; 95% CI, 0.09-0.80), having achieved anti-spike IgG >141 BAU/mL within 3 months after primary vaccination (aOR, 3.69; 95% CI, 2.68-5.07), receiving BNT162b2 vaccine as the third dose (aOR, 0.20; 95% CI, 0.10-0.41; reference, 100-µg mRNA-1273), and having previously received two doses of mRNA vaccine in primary vaccination (aOR, 2.46; 95% CI, 1,75-3.45; reference, no exposure to mRNA vaccine). CONCLUSIONS: PWH receiving different types of the third dose of COVID-19 vaccine showed similar vaccine effectiveness against SARS-CoV-2 infection. An additional dose with 100-µg mRNA-1273 could generate a higher antibody response than with 50-µg mRNA-1273 and BNT162b2 vaccine.

From June 2022 to April 2023, 1629 HIV-positive participants were assessed for the risk of atherosclerotic cardiovascular disease (ASCVD). The 10-year ASCVD risk of <5 %, 5 % to <7.5 %, ≥7.5 % to <20 % and ≥20 % were 59.9 %, 14.4 %, 20.7 % and 5.0 %, respectively; 440 (27.0 %) participants met the criteria for statin therapy, but only 171 (38.8 %) were prescribed statins.
