Human immunodeficiency type 1 (HIV‐1) DNA in peripheral blood cells of HIV‐1 infected individuals may be present as integrated and/or unintegrated DNA. Several reports have indicated that a major proportion of HIV‐1 DNA in the asymptomatic phase is linear, full‐length, and unintegrated and in the symptomatic phase either circular unintegrated or integrated in the host genome. We developed a quantitative polymerase chain reaction (PCR) technique to detect single‐LTR HIV‐1 DNA junctions, reflecting the presence of unintegrated single‐LTR circles. In vitro infection of a CD4+ T‐cell line resulted first in the increase of single‐LTR junctions followed by syncytium formation and a rise of p24 antigen production. The number of single‐LTR HIV‐1 DNA junctions was further studied in two acutely infected individuals and in 21 long‐term infected individuals. The number of single‐LTR junctions was significantly correlated with CD4+ cell decline, p24 antigen expression, and total HIV‐1 DNA content of peripheral blood mononuclear cells (PBMC). Single‐LTR HIV‐1 DNA junctions were absent from PBMC containing other forms of HIV‐1 DNA in four of nine non/slow progressors relative to 2 of 12 rapid progressors/AIDS patients.
