We observed 36 HIV-infected patients to evaluate whether the presence of tandem 2-long terminal repeat circular unintegrated HIV-1 DNA (2-LTR) in peripheral blood mononuclear cells (PBMC) at baseline was associated with acceleration of HIV disease. Detection of 2-LTR at baseline correlated with high plasma HIV-1 RNA levels (p<. 01), recovery of culturable HIV-1 from plasma (p=. 02), and progression to AIDS during follow-up (p=. 01). More patients with 2-LTR (68%) than without 2-LTR (31%) had a decline in CD4 levels of> 50 cells/mm 3 over the first 18 months of follow-up (p=. 04), and the average annual CD4 decline was 35% in patients with 2-LTR compared with 16% in those without 2-LTR (p= 0.06). Detection of 2-LTR in PBMC at baseline was an independent predictor of high plasma HIV-1 RNA levels and subsequent CD4 cell decline in this cohort of patients with predominantly nonsyncytium-inducing (NSI) isolates at baseline. The presence of 2-LTR in PBMC appears to be reflective of ongoing HIV-1 replication, as measured by plasma HIV-1 RNA levels, and identifies persons at risk for immunologic and clinical decline.
