Abstract:
Objective To describe the clinical characteristics,CD4+ and CD8+ T cell counts as well as human immunodeficiency virus (HIV) RNA of acute HIV infection in men who have sex with men,and their correlations with the disease progression.Methods One hundred cases of acute HIV infection were followed up.Nuclear acid sequence-based amplification (NASBA) was used for plasma HIV RNA screening.Flow cytometry was served to test the CD4+ and CD8+ T cell counts.Hepatitis B surface antigen (HBsAg) and anti-hepatits C virus (HCV) antibody were detected using enzyme-linked immunosorbent assay.Rapid plasma reagin was applied to screen for Treponema pallidum antibody.Antibody positive specimens were tested with Treponema pallidum particle assay for validation.The positive results were identified as infection.Results Ninety-six cases were aged between 20 and 50 years old.Among 100 cases,9 were HBsAg-positive; 4 were anti-HCV positive; 40 were co-infected with syphilis.During the follow-up period,the median CD4+ T cell counts in the 1st and 3rd month were 510/μL and 499/μL,respectively.The median HIV RNA in 1st,3rd,6th and 24th month were 4.37,4.00,4.31 and 4.43 lg copy/mL,respectively.CD8+ T cell counts did not show significant change during the study.Among 38 rapid progressors,the initial mean CD4+ T cell counts was (358.0± 134.6)/μL,which was significantly lower than that of the non-rapid progressors with a mean CD4+ T cell counts of (559.2±203.4)/μL.Meanwhile,the initial mean HIV RNA of the rapid progressors was 4.71 lg copy/ mL,while that of the non rapid progressor was 4.18 lg copy/mL.The initial CD8+ T cell counts of the rapid progressors and non rapid progressors were 1 250.1/μL and 1 247.2/μL,respectively.Conclusions Acute HIV-1 infected men who have sex with men tend to be young.The initial CD4+ T cell counts and HIV RNA during acute infection could be used to predict the disease progress.
