AB A cohort of human immunodeficiency virus (HIV)-discordant couples was
established to evaluate risk factors associated with heterosexual viral
transmission. Polymerase chain reaction (PCR) was utilized to document
the HIV-uninfected status among members of discordant heterosexual
couples and to rule out immunosilent infection. HIV DNA PCR specific for
a gag gene region was performed on peripheral blood mononuclear cell
samples from 203 HIV antibody-negative adults who have long-term
heterosexual relationships with HIV-infected partners. The results were
negative for 200 but consistently positive in three individuals. More
extensive evaluation of these three individuals with an additional
primer pair specific for the envelope gene, quantitative DNA PCR,
multiple additional time points, and variable nucleotide tandem repeat
analyses revealed specimen processing problems in two cases but an
apparent true positive PCR assay in the third case. This subject remains
antibody and PCR negative for a 32-month follow-up period. These results
confirm previous studies that document a negligible incidence of occult
HIV infection as delineated by PCR in antibody negative heterosexual
partners of HIV-infected individuals. Specimen processing errors occur
at a low rate (1% in this study) and require careful evaluation. The
possibility of transient, aborted infection versus successful infection
with a long immunosilent period was observed in a single individual.
Definitive resolution of infection status will require long-term
evaluation.
