Objective To investigate the distribution of invasive fungal infections in blood and sterile body fluids and the distribution of invasive fungal infections under different immunological characteristics among patients with HIV/AIDS in the Changsha area.Methods Retrospective analysis was performed on the basic information,fungal types,sample types,and T lymphocyte subsets collected from 414 patients with HIV/AIDS having invasive fungal infections in blood and sterile body fluids who were admitted to the First Hospital of Changsha from 2020 to 2022.Results A total of 526 strains of fungi were isolated from 414 patients with HIV/AIDS having invasive fungal infections,among which the top three fungi were Talaromyces marneffei with 380 strains(72.24%),Cryptococcus neoformans with 120 strains(22.81%),and Candida with 10 strains(1.90%).A total of 361 patients underwent CD4,CD8 cell counts during their hospital stay.There were 287 patients(79.50%)with CD4 cell count ≤50/μL and 218 patients(60.39%)with a CD4/CD8 cell ratio ≤0.10,both being predominantly infected with T.marneffei(85.02%,81.19%).The differences in the distribution of patients with three different types of invasive fungal infections were statistically significant under various CD4 cell counts and CD4/CD8 cell ratios(all P<0.01).Conclusions T.marneffei and C.neoformans were the main infections in the blood and sterile body fluids of patients with HIV/AIDS.Patients with HIV/AIDS with low immune function had a higher infection rate of T.marneffei.
