This study aims to develop and evaluate a model to predict the immune reconstitution among HIV/AIDS patients after antiretroviral therapy (ART). A total of 502 HIV/AIDS patients are randomized to the training cohort and evaluation cohort. Least absolute shrinkage and selection operator (LASSO) regression and multivariate logistic regression analysis are performed to identify the indicators and establish the nomogram for predicting the immune reconstitution. Decision curve analysis (DCA) and clinical impact curve (CIC) are used to evaluate the clinical effectiveness of the nomogram. Predictive factors included white blood cells (WBC), baseline CD4+ T-cell counts (baseline CD4), ratio of effector regulatory T cells to resting regulatory T cells (eTreg/rTreg) and low-density lipoprotein cholesterol (LDL-C) and are incorporated into the nomogram. The area under the curve (AUC) is 0.812 (95% CI, 0.767â¼0.851) and 0.794 (95%CI, 0.719â¼0.857) in the training cohort and evaluation cohort, respectively. The calibration curve shows a high consistency between the predicted and actual observations. Moreover, DCA and CIC indicate that the nomogram has a superior net benefit in predicting poor immune reconstitution. A simple-to-use nomogram containing four routinely collected variables is developed and internally evaluated and can be used to predict the poor immune reconstitution in HIV/AIDS patients after ART.

Purpose: Neuropsychiatric adverse events (NPAEs) occur frequently in people living with human immunodeficiency virus (PLWH) receiving antiretroviral therapy (ART). This study aimed to assess the dynamic trends and risk factors of NPAEs among PLWH in Hangzhou taking efavirenz (EFV)- or dolutegravir (DTG)- or elvitegravir (EVG)-based regimens. Patients and Methods: A total of 287 ART-naive PLWH were included in this study, EFV (400mg)- (n = 122), EFV (600mg)- (n = 37), DTG- (n = 73), EVG-based (n = 47) and other ART regimens (n = 8) as the initial ART regimen were administered for 12 months. All data were collected at five time points within a 12-month follow-up. The Pittsburgh Sleep Quality Index and Hospital Anxiety and Depression Scale were used to evaluate sleep disorders and anxiety and depression symptoms, respectively. The dynamic trends and potential risk factors of NPAEs were investigated using a generalized linear mixed model. Results: Mean age was 29.4 (SD: 7.5) years with 97.2% males. After 12 months of ART, the prevalence of sleep disorders and anxiety decreased significantly, although only a slight improvement was observed for depression. In addition, there was a significant positive correlation between sleep disorders, anxiety, and depression. The risk factors for NPAEs differed slightly depending on the choice of ART regimen, but the seven factors most commonly associated with NPAEs were age, sex, marital status, education level, smoking status, body mass index, and WHO clinical stage. Treatment-induced changes in CD4-positive T-cell count and virological suppression did not depend on the particular choice of ART regimen. Conclusion: The prevalence of sleep disorders and anxiety changed significantly over time on ART and the risks of these disorders were associated with seven common clinical and demographic factors.
ABSTRACT
Mitochondrial mass (MM) is considered an essential parameter of the immune system, but the association of MM with incomplete immune reconstitution (IIR) in people living with HIV (PLWH) remains unclear. Here, we tested 2148 blood samples from 1999 PLWH by flow cytometry in China between August 2021 and February 2022. A novel U-shaped relationship, determined by multivariable smooth curve fitting and piecewise-linear mixed-effect model, was observed between the ratio of MM to SD (MM/SD) and IIR, with a threshold cutoff of 2.8. For MM/SD <2.8, per SD increment of MM was independently associated with 30%, 30%, 20%, and 20% decreased risk of CD4+ T-cell counts <500 cells/µL after 4 years of treatment and CD4+ T-cell counts <350 cells/µL after 4, 5, 6 years of treatment, respectively. Our study suggested that increasing MM may indicate the low risk of IIR for PLWH with MM/SD <2.8.

Diagnosis of neurosyphilis is currently based on the cerebrospinal fluid (CSF) assessments and CSF-Venereal Disease Research Laboratory (CSF-VDRL) is the traditional "gold standard." In the real world, CSF assessments and CSF-VDRL are not always available. This study aimed to identify noninvasive predictors of neurosyphilis based on real-world clinical parameters and diagnostic criteria in populations with different HIV status. In this retrospective cohort study, syphilis patients with different HIV statuses hospitalized for neurosyphilis screening were retrospectively recruited at an infectious disease hospital. Neurosyphilis was defined by real-world diagnostic criteria. Logistic regression and receiver operating characteristic curve analysis were used to investigate and evaluate predictors of neurosyphilis. In total, 528 patients were enrolled, including 143 syphilis patients without HIV infection and 385 HIV/syphilis-co-infected patients. One hundred twelve and 304 neurosyphilis patients were identified in the HIV-negative and HIV-positive groups, respectively. A high serum toluidine red unheated serum test (TRUST) titer was a robust predictor of neurosyphilis in all participants. An age ≥50 years old [adjusted odds ratio (aOR) = 5.062, 95% confidence interval (CI), 1.449-17.680] in the HIV-negative group and CD4+ T cell count <330/µL (<300 as reference, aOR = 0.552, 95% CI, 0.315-0.966) in the HIV-positive group were predictors of asymptomatic neurosyphilis. In real-world situations, for asymptomatic syphilis patients, relatively old age and a high serum TRUST titer in HIV-negative populations, and CD4+ T cells <330/µL and/or serum TRUST titer >1:64 in HIV-positive populations might predict neurosyphilis.
