AbFew reports have shown the relationship between the distribution of human immunodeficiency virus type 1 (HIV-1) proviral DNA in CD4 subsets during acute HIV-1 infection and HIV disease progression. In this study, we enrolled two groups with distinct differences in disease progression. The CD4 counts of one group fell below 200 cells/μL within 2 years (rapid progressors), whereas the other group maintained CD4 counts above 500 cells/μL (slow progressors). We collected blood samples during Fiebig stage III-IV of the two groups, and sorted CD4+ naïve, central memory, and effector memory lymphocytes. Real-time polymerase chain reaction was used to quantify HIV-1 DNA of the subsets. We found that HIV-1 DNA content was higher in memory T-cells than in naïve cells in both groups, and a higher HIV DNA content was found in naïve CD4+ T-cells during acute HIV-1 infection in rapid progressors. This suggests that higher HIV DNA in naïve CD4+ T-cells may associated with rapid progression.
