Background Blastocystis hominis(Bh)is zoonotic parasitic pathogen with a high prevalent globally,causing opportunistic infections and diarrhea *** immunodeficiency virus(HIV)infection disrupts the immune system by depleting CD4^(+)T lymphocyte(CD4^(+)T)cell counts,thereby increasing Bh infection risk among persons living with HIV(PLWH).However,the precise association between Bh infection risk and HIV-related biological markers and treatment processes remains poorly ***,the purpose of the study was to explore the association between Bh infection risk and CD4^(+)T cell counts,HIV viral load(VL),and duration of interruption in antiviral therapy among *** A large-scale multi-center cross-sectional study was conducted in China from June 2020 to December *** genetic presence of Bh in fecal samples was detected by real-time fluorescence quantitative polymerase chain reaction,the CD4^(+)T cell counts in venous blood was measured using flowcytometry,and the HIV VL in serum was quantified using fluorescence-based *** cubic spline(RCS)was applied to assess the non-linear association between Bh infection risk and CD4^(+)T cell counts,HIV VL,and duration of interruption in highly active antiretroviral therapy(HARRT).Results A total of 1245 PLWH were enrolled in the study,the average age of PLWH was 43 years[interquartile range(IQR):33,52],with 452(36.3%)being female,50.4%(n=628)had no immunosuppression(CD4^(+)T cell counts>500 cells/μl),and 78.1%(n=972)achieved full virological suppression(HIV VL<50 copies/ml).Approximately 10.5%(n=131)of PLWH had *** prevalence of Bh was found to be 4.9%[95%confidence interval(CI):3.8-6.4%]among *** nonlinear associations were observed between the Bh infection risk and CD4^(+)T cell counts(Pfor nonlinearity<0.001,L-shaped),HIV VL(Pfor nonlinearity<0.001,inverted U-shaped),and duration of interruption in HARRT(Pfor nonlinearity<0.001,inverted U-shaped).Conclusions
