Abstract:
Objective:To investigate the immune reconstitution of HIV/AIDS patients and its influencing factors after receiving antiviral therapy (ART) in Hangzhou City, so as to provide insights into improving the treatment effects and quality of life in HIV/AIDS patients.
Methods:A retrospective cohort of HIV/AIDS patients who began antiviral treatment between January 1, 2016 and August 31, 2021 and had a baseline CD4+T lymphocyte (CD4) counts of less than 500 cells/μL or a baseline CD4/CD8+T lymphocyte (CD8) ratio of less than 0.8 in Hangzhou City was followed up until August 31, 2023. Demographic information, antiviral therapy in formation, CD4 counts, and CD4/CD8 were collected from the Chinese Disease Prevention and Control Information System. A good immune reconstitution was defined as having CD4≥500 cells/μL and CD4/CD8≥0.8. The immune reconstitution status of HIV/AIDS patients were analyzed, and factors affecting immune reconstitution were identified using a multivariable Cox proportional risk regression model.
Results:A total of 3 349 HIV/AIDS patients were enrolled, with a median age at ART of 31 (interquartile range, 20) years. There were 3 075 males (91.82%), 1 600 cases with college education and above (47.78%) and 2 455 cases at WHO clinical stage Ⅰ-Ⅱ(73.31%). There were 1 368 cases with good immune reconstitution, accounting for 40.85%, and the proportion of HIV/AIDS patients with good immune reconstitution that began ART in 2016 was the highest, reaching 51.90%. Multivariable Cox proportional risk regression model identified WHO clinical stage (Ⅰ-Ⅱ, HR=2.529, 95%CI: 2.023-3.162), timely ART (HR=1.196, 95%CI: 1.027-1.394), initial treatment regimen (TDF+3TC+NVP/EFV, HR=2.185, 95%CI: 1.891-2.524; integrase inhibitors, HR=8.509, 95%CI: 6.706-10.795), baseline CD4/CD8 (≥0.1, HR: 1.600-4.515, 95%CI: 1.061-6.661), baseline hemoglobin (<90 mg/dL, HR=0.327, 95%CI: 0.121-0.880), hepatitis B infection (HR=0.619, 95%CI: 0.457-0.840) and hepatitis C infection (HR=0.308, 95%CI: 0.099-0.956) as factors affecting immune reconstitution in HIV/AIDS patients.
Conclusion:The immune reconstitution in HIV/AIDS patients after ART is associated with WHO clinical stage, timely ART, initial treatment regimen, baseline CD4/CD8, baseline hemoglobin and hepatitis B or C infection.
