Objective Men who have sex with men (MSM) living with HIV are more likely to suffer from mental health problems. They should be given adequate attention to treat and improve their mental health disorders. This meta-analysis aimed to assess whether psychosocial interventions reliably improve psychological well-being among MSM living with HIV. Method Cochrane Library, EMBASE, PsycINFO, and PubMed were searched for psychosocial intervention randomized controlled trials evaluating mental health (e.g., depression, anxiety, self-efficacy). The effect size was pooled using the random-effects model, and continuous outcomes were reported using standardized mean difference (SMD) values . Results A total of 12 studies including 1782 participants were included in the meta-analysis. Psychosocial interventions in contrast to control groups significantly reduced depression (SMD, − 0.28; 95% CI − 0.52 – − 0.03) at the follow-up assessment and improved quality of life (SMD 0.43, 95% CI 0.23–0.63) after treatment. Psychosocial interventions also had a significant effect on measures of self-efficacy (SMD 2.22, 95% CI 0.24–4.20), and this effect was sustained until long-term follow-up (SMD 0.55, 95% CI 0.02–1.08). Subgroup analyses revealed that improvements in depression were more significant when participants possessed higher education and treatment providers used cognitive behavioral therapy (CBT). Conclusions The findings of this study indicate that psychosocial interventions benefit the mental health of MSM living with HIV. It is necessary to conduct more research to explore characteristics that may affect treatment outcomes in the future. Trial registration This research was prospectively registered in PROSPERO (CRD42021262567).

Syphilis is an important health problem worldwide; however, few studies have probed the impact of syphilitic infection on T cell turnover. The mechanisms behind the frequency of T cell subset changes and the associations between these subsets during syphilitic infection remain unclear. Herein, we used a cell-staining method and flow cytometry to explore changes in T cell subpopulations and potential contribution of apoptosis and pyroptosis that triggered therein. We investigated caspase-1-mediated pyroptosis and caspase-3-mediated apoptosis of CD4+ and CD8+ T cells, the major effector lymphocytes with pivotal roles in the pathogenesis of infectious diseases. We found that the levels of caspase-1 and caspase-3 increased in both the circulation and intracellularly in CD4+ and CD8+ T cells. Caspase-1 showed a continual increase from early latent stage infection through to phase 2 disease, whereas caspase-3 increased through to phase 1 disease but declined during phase 2. In addition, serum levels and intracellular expression of caspase-1 and caspase-3 were positively correlated. Overall, this study increases our understanding of how syphilitic infection influences CD4+ and CD8+ T-cell turnover, which may help with designing novel and effective strategies to control syphilis infection and prevent its transmission.

Some syphilis patients do not exhibit an appropriate serological response after treatment despite the absence of any clinical evidence of treatment failure or reinfection. This condition is called “serofast syphilis” or “serological non-response syphilis.” This study explored the incidence of asymptomatic neurosyphilis (ANS) and related factors in 324 asymptomatic patients with serological non-response syphilis. We analyzed descriptive statistics stratified by the presence of asymptomatic neurosyphilis for the basic characteristics of samples. Bivariate analysis was conducted to assess correlations between outcomes and potential predictors. Variables significant in the bivariate analysis (p1:32. Our findings suggest that ANS is common among syphilis patients, and patients with a fourfold decrease in serum RPR titers after treatment and current serum RPR titers >1:32 are more likely to develop ANS.

Recently identified T memory stem (Tscm) cells have stem-cell-like properties, including long lifespan, self-renewal capacity, and multipotency to differentiate into other memory T cell types. In the study of simian immunodeficiency virus (SIV) infection, selective depletion of CCR5

This study investigated whether treatment with IFN-α and ribavirin (RBV) reduces 2LTR circular HIV DNA in addition to the total and integrated HIV DNA. Two groups of patients were enrolled. Group 1 comprised HIV/HCV co-infected patients who were treated with highly active antiretroviral therapy (HAART), IFN-α and RBV for 48 weeks. After the 48 weeks of treatment, IFN-α and RBV treatment was discontinued and HAART was continued. Group 2 comprised HIV-infected patients who were treated with HAART. Real-time polymerase chain reaction (RT-PCR) was used to quantify the levels of HIV-1 DNA. We found that compared with Group 2 patients, Group 1 patients exhibited an obvious decrease in the CD4 cell count and the total DNA, 2LTR circular DNA, and integrated HIV DNA after 48 weeks of treatment. After the discontinuation of IFN-α and RBV treatment in Group 1 patients, the levels of HIV DNA recovered. Therefore, we concluded that treatment with IFN-α and ribavirin (RBV) reduces 2LTR circular HIV DNA.
