Objective:To explore the risks of cardiovascular disease (CVD) and influencing factors in human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients with long-term combination anti-retroviral therapy (cART).Methods:The baseline data from the multi-center prospective cohort of HIV/AIDS patients who received long-term cART from 2018 to 2020 were collected. cART-naive HIV/AIDS patients were matched by age and gender using the propensity score matching (PSM) as controls. Data collection adverse events of anti-human immunodeficiency virus drugs reduced model (D: A: D[R]) score, Framingham risk score (FRS) and atherosclerotic cardiovascular disease (ASCVD) risk score were used to assess the 10-year CVD risk in patients with long-term cART treatment and in cART-naive patients. Logistic regression analysis was used to assess the risk factors related to high 10-year CVD risk.Results:A total of 301 HIV/AIDS patients received long-term cART and 300 cART-naive HIV/AIDS patients were included, with an average age of 39.8 years old. There were 490 male accounting for 81.5%. Based on the D: A: D [R] score, 4.3%(13/301) of patients in the long-term cART group had a 10-year CVD risk assessment of ≥10%, and 6.3%(19/300) of patients in the cART-naive group. Based on the FRS, 13.4%(36/269) of patients in the long-term cART group had a 10-year CVD risk assessment of ≥10%, and 10.6%(28/264) in the cART-naive group. Based on the ASCVD risk score, 10.4%(14/135) of patients in the long-term cART group had a 10-year CVD risk assessment of ≥7.5%, and 13.8%(17/123) in the cART-naive group. There was no significant difference in the prevalence of high 10-years CVD risk between the long-term cART group and the cART-naive group assessed by any of risk equations (all P>0.050). By multivariate logistic regression analysis, the risk factors associated with 10-year CVD risk ≥10% assessed by D: A: D[R] model were age≥50 years, smoking, hypertension, diabetes, dyslipidemia and CD4 + T lymphocyte count <200×10 6 cells/L (adjusted odds ratio ( AOR)=697.48, 4 622.28, 23.11, 25.95, 27.72 and 18.25, respectively, all P<0.010). The risk factors associated with 10-year CVD risk ≥10% assessed by FRS were age≥50 years, male, smoking, hypertension, diabetes and dyslipidemia ( AOR=53.51, 4.52, 36.93, 36.77, 6.15 and 3.84, respectively, all P<0.050). The risk factors associated with 10-year CVD risk ≥7.5% assessed by ASCVD risk score were age≥50 years, male, smoking, hypertension, diabetes ( AOR=18.48, 14.11, 14.81, 13.42 and 12.41, respectively, all P<0.050). Conclusions:Long-term cART has no significant effect on the 10-year CVD risk in HIV/AIDS patients. Higher CVD risk in HIV/AIDS patients are mainly associated with CD4 + T lymphocyte counts<200×10 6 cells/L and traditional CVD risk factors, including age≥50 years old, smoking, hypertension, diabetes and dyslipidemia.

COVID-19 is caused by a novel coronavirus-severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2), which has being spreading around the world, posing a serious threat to human health and lives. Neutralizing antibodies and small molecule inhibitors for virus replication cycle are the main antiviral treatment for novel coronavirus recommended in China. To further promote the rational use of antiviral therapy in clinical practice, the National Center for Infectious Diseases (Beijing Ditan Hospital Capital Medical University and the First Affiliated Hospital, Zhejiang University School of Medicine) invited experts in fields of infectious diseases, respiratory and intensive care to develop an Expert Consensus on Antiviral Therapy of COVID-19 based on the Diagnosis and Treatment Guideline for COVID-19 ( trial version 10) and experiences in the diagnosis and treatment of COVID-19 in China. The consensus is concise, practical and highly operable, hopefully it would improve the understanding of antiviral therapy for clinicians and provide suggestions for standardized medication in treatment of COVID-19.

BACKGROUND: Previous studies have examined the bulk transcriptome of peripheral blood immune cells in acquired immunodeficiency syndrome patients experiencing immunological non-responsiveness. This study aimed to investigate the characteristics of specific immune cell subtypes in acquired immunodeficiency syndrome patients who exhibit immunological non-responsiveness. METHODS: A single-cell transcriptome sequencing of peripheral blood mononuclear cells obtained from both immunological responders (IRs) (CD4 + T-cell count >500) and immunological non-responders (INRs) (CD4 + T-cell count <300) was conducted. The transcriptomic profiles were used to identify distinct cell subpopulations, marker genes, and differentially expressed genes aiming to uncover potential genetic factors associated with immunological non-responsiveness. RESULTS: Among the cellular subpopulations analyzed, the ratios of monocytes, CD16 + monocytes, and exhausted B cells demonstrated the most substantial differences between INRs and IRs, with fold changes of 39.79, 11.08, and 2.71, respectively. In contrast, the CD4 + T cell ratio was significantly decreased (0.39-fold change) in INRs compared with that in IRs. Similarly, the ratios of natural killer cells and terminal effector CD8 + T cells were also lower (0.37-fold and 0.27-fold, respectively) in the INRs group. In addition to several well-characterized immune cell-specific markers, we identified a set of 181 marker genes that were enriched in biological pathways associated with human immunodeficiency virus (HIV) replication. Notably, ISG15 , IFITM3 , PLSCR1 , HLA-DQB1 , CCL3L1 , and DDX5 , which have been demonstrated to influence HIV replication through their interaction with viral proteins, emerged as significant monocyte marker genes. Furthermore, the differentially expressed genes in natural killer cells were also enriched in biological pathways associated with HIV replication. CONCLUSIONS We generated an atlas of immune cell transcriptomes in HIV-infected IRs and INRs. Host genes associated with HIV replication were identified as markers of, and were found to be differentially expressed in, different types of immune cells.

Objective To investigate the risk factors for short-term prognosis in patients with HBV-related acute-on-chronic liver failure (ACLF). Methods A retrospective analysis was performed for the clinical data of 119 patients with HBV-related ACLF who were admitted to Mengchao Hepatobiliary Hospital of Fujian Medical University from October 2019 to October 2020, and according to their survival status on day 90, they were divided into death group and survival group. The patients were given antiviral therapy with entecavir or tenofovir. Related clinical data were collected, including alanine aminotransferase (ALT), aspartate aminotransferase, cholinesterase (ChE), albumin (Alb), cholesterol, alpha-fetoprotein, and HBV DNA at baseline, as well as the incidence rate of important complications. Model for End-Stage Liver Disease (MELD) score was also calculated. The t -test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and the chi-squared test was used for comparison of categorical data between two groups; a logistic regression analysis was used to investigate the influencing factors for the 90-day prognosis of patients with HBV-related ACLF and establish a new predictive model; the receiver operating characteristic (ROC) curve was used to evaluate the diagnostic efficiency of the new model in predicting the prognosis of HBV-related ACLF. Results Of all patients, 33 died within 90 days, resulting in a mortality rate of 27.7%. There were significant differences between the survival group and the death group in age, ALT, Alb, ChE, MELD score, and incidence rates of hepatic encephalopathy, primary peritonitis, and hepatorenal syndrome (all P < 0.05). The logistic regression analysis showed that baseline hepatic encephalopathy (odds ratio [ OR ]=10.404, 95% confidence interval [ CI ]: 2.522-42.926, P =0.001), serum Alb at baseline ( OR =0.853, 95% CI : 0.764-0.952, P =0.005), and MELD score at baseline ( OR =1.143, 95% CI : 1.036-1.261, P =0.008) were independent predictive factors for the short-term prognosis of patients with HBV-related ACLF. A new predictive model was established based on the combination of these three indices, and the ROC curve analysis showed that this new model had an area under the curve of 0.833, while MELD score had an area under the ROC curve of 0.672. Conclusion As for the evaluation of the 90-day prognosis of patients with HBV-related ACLF, the new prognostic model established based on hepatic encephalopathy, Alb, and MELD score has a better predictive value than MELD score alone.
