Abstract Background We previously reported T-cell senescence to be similar in people with human immunodeficiency virus (PWH) with suppressed viremia (predominantly men who have sex with men [MSM]) and human immunodeficiency virus (HIV)-negative otherwise comparable controls but greater than in healthy blood donors. This led us to compare CD4+ and CD8+ T-cell counts and CD4+/CD8+ ratios between HIV-negative MSM and men who only have sex with women (MSW) and relate observed differences in behavioral factors and infectious exposures, including cytomegalovirus (CMV) infection. Methods In 368 HIV-negative MSM and 72 HIV-negative MSW, T lymphocyte phenotyping was performed 3 times biennially. Baseline CMV serology and sexually transmitted infection (STI) incidence and/or STI seroprevalence, sexual, and substance-use behavior data were collected during study visits. Results Men who have sex with men, compared with MSW, had higher CD8+ counts (551 vs 437 cells/mm3, P < .001), similar CD4+ counts (864 vs 880 cells/mm3, P = .5), and lower CD4+/CD8+ ratios (1.84 vs 2.47, P < .001). Differences were most pronounced for MSM with >10 recent sex partners and partly explained by higher CMV seroprevalence in MSM. Conclusions These findings suggest that factors other than HIV may, in both PWH and certain HIV-negative MSM, contribute to a low CD4+/CD8+ ratio. Whether this, like in PWH, contributes to comorbidity risk in HIV-negative MSM requires further study.

Abstract Background Whether accelerated aging develops over the course of chronic human immunodeficiency virus (HIV) infection or can be observed before significant immunosuppression on is unknown. We studied DNA methylation in blood to estimate cellular aging in persons living with HIV (PLWH) before the initiation of antiretroviral therapy (ART). Methods A total of 378 ART-naive PLWH who had CD4 T-cell counts >500/µL and were enrolled in the Strategic Timing of Antiretroviral Therapy trial (Pulmonary Substudy) were compared with 34 HIV-negative controls. DNA methylation was performed using the Illumina MethylationEPIC BeadChip. Differentially methylated positions (DMPs) and differentially methylated regions (DMRs) in PLWH compared with controls were identified using a robust linear model. Methylation age was calculated using a previously described epigenetic clock. Results There were a total of 56 639 DMPs and 6103 DMRs at a false discovery rate of <0.1. The top 5 DMPs corresponded to genes NLRC5, VRK2, B2M, and GPR6 and were highly enriched for cancer-related pathways. PLWH had significantly higher methylation age than HIV-negative controls (P = .001), with black race, low CD4 and high CD8 T-cell counts, and duration of HIV being risk factors for age acceleration. Conclusions PLWH before the initiation of ART and with preserved immune status show evidence of advanced methylation aging.

Introduction: Recent studies worldwide reveal a significant prevalence of extragenital infections by Neisseria gonorrhoeae among men who have sex with men. We aimed to analyse the frequency and characteristics of extragenital gonococcal infections diagnosed in men who have sex with men in a walk-in Sexually Transmitted Infection clinic in Lisbon, Portugal.Material and Methods: We conducted a cross-sectional, retrospective study of the anorectal and/or oropharyngeal Neisseria gonorrhoeae infections in men who have sex with men, diagnosed in our Sexually Transmitted Infection clinic between January 2014 and December 2016.Results: We found extragenital infection in 87 cases of gonorrhoea identified in men who have sex with men in this period, including: 49 cases of anorectal disease, 9 of oropharyngeal disease, 13 cases of infection at both extragenital sites, and 16 of simultaneous extragenital and urogenital gonorrhoea. Patients’ ages ranged from 17 to 64 years (median: 28 years). Forty-seven (54%) of the patients did not present with any extragenital symptoms. Thirty (35%) were human immunodeficiency virus-1-positive.Discussion: Since most extragenital Neisseria gonorrhoeae infections are asymptomatic, they may be missed and go untreated unless actively investigated. Current international guidelines recommend the screening of gonorrhoea at extragenital sites in men who have sex with men because anorectal and oropharyngeal infections constitute a potential disease reservoir, and may facilitate transmission and/or acquisition of human immunodeficiency virus infection.Conclusion: Our results highlight the relevance of testing men who have sex with men for Neisseria gonorrhoeae at extragenital sites, regardless of the existence of local complaints. The implementation of adequate screening programmes in Portugal should be considered. We also reinforce the need to raise awareness in the population regarding the adoption of prophylactic measures against transmission of sexually transmitted infections during anal and/or oral sexual exposure.

Abstract Background Sub-Saharan Africa is a region of both high human immunodeficiency virus (HIV) and anal cancer incidence. We conducted the first national study in Togo to assess human papillomavirus (HPV), HIV, and other sexually transmitted infection (STI) prevalence among men who have sex with men (MSM). Methods A multicentric cross-sectional study was conducted among MSM recruited in 4 Togolese cities. Anal swabs were collected to test HPV, herpes simplex virus (HSV), and 7 STIs. Results Among the 207 MSM, HIV and high-risk HPV (hrHPV) overall prevalence were 26.1% and 44.9%, respectively. The most common hrHPV types were HPV-35 (15.0%) and HPV-16 (13.0%). Prevalence of hrHPV and multiple HPV infections were higher among HIV-infected than among HIV-uninfected MSM (85.2% vs 30.7%, P < 10–5 and 85.2% vs 28.7%, P < 10–5, respectively). Other STIs, except hepatitis B virus, were also more prevalent among HIV-infected MSM (Neisseria gonorrhoeae, P = .03; Mycoplasma genitalium, P = .04; HSV-2, P = .001; and a trend for Chlamydia trachomatis, P = .06). In multivariate analysis (adjusted odds ratio [95% confidence interval]), HIV (10.1 [4.0–25.6]), living in Lomé (2.8 [1.1–7.1]), HSV-2 excretion (26.7 [2.9–244.3]), C. trachomatis (11.7 [2.3–58.9]), and M. genitalium infection (9.6 [3.1–29.9]) were associated with increased risk of hrHPV infection. Conclusions We report a high burden of anal STIs with an unusual hrHPV type distribution among MSM, highlighting the critical need of implementation of a national strategy regarding prevention of STIs and vaccination against HPV.
