Incidence, clearance, and factors associated with anal human papilloma virus infection among men with HIV.

OBJECTIVES: This study aims to estimate the incidence and persistence/clearance of anal human papilloma virus (HPV) infection and related factors among men with HIV in Taizhou, China. DESIGN: A prospective cohort study. METHODS: Men with HIV were recruited and followed up from 2016 to 2021. Questionnaire surveys were used to collect social-demographic and behavioral characteristics, and anal swabs were collected for HPV Genotyping. RESULTS: A total of 675 men with HIV were recruited and followed up. After an average follow-up time of 1.75 years, HPV39 (3.8/100 person-years), HPV52 (3.6/100 person-years), HPV51 (3.1/100 person-years), HPV58 (2.5/100 person-years) and HPV16 (2.4 cases/100 person-years) in the high-risk types showed the highest incidence rate. In marriage with woman [adjusted hazard ratio (aHR) = 0.44, 95% confidence interval (CI) 0.20-0.99] showed an inverse association with HPV incidence, while bisexuality or undetermined sexual orientation (aHR = 2.62, 95% CI 1.08-6.36) showed a positive association. For those infected at baseline, the top three high-risk HPV with the lowest clearance density were HPV52 (32.2/100 person-years), HPV58 (38.1/100 person-years), and HPV16 (43.5/100 person-years). Daily consumption of 1-28 g alcohol (aHR = 0.62, 95% CI 0.41-0.95) showed an inverse association with HPV clearance, while illicit drug use (aHR = 3.24, 95% CI 1.59-6.59) showed a positive association. CONCLUSION: Anal HPV infection and clearance were both active in men with HIV in China. Marriage status and sexuality were associated with the incidence of HPV infection, while substance use including alcohol and illicit drug were associated with HPV clearance. More studies are needed to explore the risk factors of HPV persistence.

Comparison of Recovery Effect for Sufentanil vs. Remifentanil Anesthesia in Elderly Patients Undergoing Curative Resection for Hepatocellular Carcinoma.

INTRODUCTION: The aim of this work is to evaluate the clinical efficacy and safety of sufentanil vs. remifentanil anesthesia in elderly patients undergoing curative resection for hepatocellular carcinoma (HCC). METHODS: Medical records of elderly patients aged ≥ 65 years who received curative resection for HCC between January 2017 and December 2020 were retrospectively reviewed. The patients were divided into either the sufentanil group or the remifentanil group according to the method of analgesia used. Vital signs including mean arterial pressure (MAP), heart rate (HR), and arterial oxygen saturation (SpO2), distribution of T-cell subsets (CD3, CD4, and CD8 lymphocytes), distribution of the stress response index [cortisol (COR), interleukin (IL)-6, C-reactive protein (CRP), and glucose (GLU)] were recorded prior to anesthesia (T0), after induction of anesthesia (T1), at the end of surgery (T2), 24 h after surgery (T3), and 72 h after surgery (T4). Postoperative adverse events were collected. RESULTS: Repeated measure analysis of variance (ANOVA) showed that after controlling for baseline patient demographic and treatment characteristics as covariates, both between- and within-group effects were significant (all P < 0.01), and the interaction between time and treatments was also significant (all P < 0.01) in the vital signs (MAP, HR, and SpO2), distribution of T-cell subsets (CD3, CD4, and CD8 lymphocytes), and distribution of the stress response index (COR, IL-6, CRP, and GLU), indicating that sufentanil led to stable hemodynamic and respiratory functions, lower reduction of T-lymphocyte subsets, and stable stress response indices compared to remifentanil. There is no significant difference in adverse reactions between the two groups (P = 0.72). CONCLUSIONS: Sufentanil was associated with improved hemodynamic and respiratory function, less stress response, less inhibition of cellular immunity, and similar adverse reactions compared with remifentanil.

Increased CD4+ T cell count is associated with lower anal human papillomavirus prevalence among HIV-positive male cohort in Taizhou, China: a cross-sectional study.

OBJECTIVES: This study aims to investigate the association between CD4+ T cell count and combined antiretroviral therapy (cART) with the prevalence of anal human papillomavirus (HPV) infection among HIV-positive male cohort in China. METHODS: A survey was conducted in men from a HIV cohort in Taizhou, China between 2016 and 2019. A face-to-face questionnaire interview was administered, and an anal-canal swab was collected for HPV genotyping. RESULTS: A total of 766 HIV-positive men were recruited. The HPV prevalence was lower among those with increased CD4+ T cell count than those with decreased or unchanged (46.5 vs. 56.6%, p = 0.033) from baseline. In multivariable models, having the current CD4+ T cell count of 350-499 cells/µL (aOR 0.28, 95% CI 0.13-0.64), and of ≥ 500 cells/µL (aOR 0.26, 95% CI 0.11-0.60) were associated with lower prevalence of any type HPV infection compared with those with < 200 cells/µL. Having taken NVP + 3TC + AZT was inversely associated with any high-risk (HR)-HPV (aOR 0.47, 95% CI 0.25-0.90) and any low-risk (LR)-HPV infection (aOR 0.40, 95% CI 0.18-0.88), compared with those taking EFV + 3TC + TDF. CONCLUSIONS: Increased CD4+ T cell count at follow-up was significantly associated with lower prevalence of anal HPV infection. Inverse associations between NVP + 3TC + AZT and HR-HPV or LR-HPV infecton were observed.
