Abstrakt: The prevalence of AIDS and mortality rates among HIV-infected individuals in Guangxi remain relatively high, potentially due to impaired CD4 + cell recovery. This study aims to identify factors hindering CD4 + cell recovery in people living with HIV. We conducted a retrospective study on people living with HIV in Guangxi, China, with data collection extending to the end of 2023. CD4 + T cells were categorized into "immunological responders" and "non-responders" based on CD4 + cell recovery after treatment. Multivariate logistic regression was used to analyze factors associated with the development of immunological non-responders. Recovery of CD4 + T lymphocytes was assessed using the Generalized Additive Mixed Model (GAMM) and Generalized Estimating Equations (GEE). Additionally, multivariate Cox regression identified factors influencing survival rates. Our findings indicated a 52.44% incidence of immunological non-responders after two years of treatment. Factors such as age, sex, education, occupation, infection route, pre-treatment CD4 + T cell count, HIV subtype, and treatment regimen were linked to immunological non-response. Specifically, male gender, education up to high school, farming occupation, heterosexual transmission, CRF01_AE subtype, pre-treatment CD4 + T cell count < 200/µL, and the 3TC + EFV + TDF regimen were identified as significant risk factors. Statistically significant differences in CD4 + T lymphocyte recovery rates were observed among different HIV subtypes (P < 0.05). Beyond age, sex, ethnicity, occupation, subtype, and treatment regimen, being an immunological non-responder was found to be a risk factor for both mortality and accelerated disease progression. The study highlights the complexity of factors affecting CD4 + cell recovery post-HIV treatment in Guangxi and underscores the need for vigilant clinical monitoring of people living with HIV, particularly those with low pre-treatment CD4 + T cell levels.
