Objective: To assess the prevalence and factors associated with significant hepatic steatosis (SHS, steatosis involving ≥10% hepatocytes) in HIV-infected patients.
Design: A prospective, cross-sectional study.
Methods: Five hundred and five HIV-infected patients were included in this study. All patients underwent a transient elastography examination with the controlled attenuation parameter (CAP). SHS was defined using the previously identified CAP cut-off of 238 dB/m. We analysed the associations between SHS and demographics, metabolic data, coinfections and drug therapy.
Results: SHS was detected in 201 (40%) patients. Individuals with and without plasma HIV RNA of 50 copies/ml or less presented SHS in 168 (42%) and 33 (31%) cases, respectively (P = 0.030). Patients with SHS compared with those without SHS presented higher median (IQR) BMI [BMI, 25.6 (22.5-28) vs. 22.3 (20.3-24.2) kg/m; P < 10], DBP [79 (72-85) vs. 74 (68-81) mmHg; P = 0.0001], fasting plasma glucose [95 (87-106) vs. 91 (84-97) mg/dl; P = 0.002] and triglycerides [128 (92-189) vs. 109 (80-167) mg/dl; P = 0.002], and lower HDL cholesterol [44 (37-54) vs. 48 (40-59), mg/dl; P = 0.004]. In multivariate analysis, the only factor associated with SHS was BMI [per unit increase, adjusted odds ratio (95% confidence interval) 1.34 (1.22-1-47); P < 10].
Conclusion: SHS measured by CAP is highly prevalent among HIV-infected patients. High BMI is the main predictor of SHS in this setting.

Research progress of femoral head necrosis in HIV-infected patients.
Ann Med
December 2025
Department of Joint and Sports Medicine, Zhongnan Hospital, Wuhan University, Wuhan, China.
As life expectancy among patients infected with the human immunodeficiency virus (HIV) increases, a growing number of complications have been observed. This population displays an elevated risk of ischemic necrosis of the femoral head in comparison to the general population, which may be attributed to HIV infection, antiretroviral medication use, and hormone application. Patients infected with the human immunodeficiency virus (HIV) who also have necrosis of the femoral head tend to present at an earlier age, with a rapid disease progression and a high incidence of bilateral onset.

Objective: This study aimed to update baseline data on monkeypox (mpox)-related knowledge and vaccination willingness among human immunodeficiency virus (HIV) diagnosed and suspected males.
Methods: The cross-sectional survey was conducted in Changsha, a provincial capital in China, during 5 JULY to 5 SEPTEMBER 2023. Among the three study groups, the participants in the "previously diagnosed" group were recruited from a cohort of HIV-infected patients.

Purpose: To investigate the clinical features and risk factors of the human immunodeficiency virus (HIV)-infected patients with intracerebral hemorrhage (ICH).
Patients And Methods: The patients with HIV-infected without ICH group were matched to the group of HIV-infected ICH patients. Logistic regression analysis using 1:1 propensity score matching (PSM) was performed to investigate the independent risk factors for ICH in HIV-infected patients.

Objective: To investigate the incidence of anemia and evaluate the immune status among newly reported HIV/AIDS patients in Jiangsu Province in 2021, and to identify the risk factors of anemia among patients living with HIV infections.
Methods: Newly reported HIV/AIDS patients in Jiangsu Province from January 1 to December 31, 2021 that were registered in China's National AIDS Comprehensive Control Information Management System were enrolled. Subjects' fresh whole blood samples were collected, and hemoglobin levels, CD4 and CD8 cell counts and HIV viral loads were measured.
Background: Non-malarial febrile illnesses (NMFI) pose significant challenges in HIV-infected children, often leading to severe complications and increased morbidity. While traditional diagnostic approaches focus on specific pathogens, shotgun metagenomic sequencing offers a comprehensive tool to explore the microbial landscape underlying NMFI in this vulnerable population ensuring effective management.
Methods: In this study, we employed shotgun metagenomics to analyse stool samples from HIV-infected children at the Baylor Children's Clinic Uganda presenting with non-malarial febrile illness.
