AB OBJECTIVE: Early determination of HIV infection status (infected and not
infected) in infants born to HIV-seropositive mothers. METHODS:
Application of 4 diagnostic rules based on either single or combination
conventional laboratory assays (HIV culture of PBMC, DNA PCR, and serum
HIV p24 antigen) of sequential blood samples taken from 183 such
infants. Clinical findings and serology were utilized as endpoints:
Infected, AIDS defining illness or seropositivity > or = 15 months; n =
51; Uninfected, seroreversion, any age, n = 132. RESULTS: The most
useful algorithm defined by age 3 mo., with 90% sensitivity and
specificity, an infant as infected (2 consecutive PCR positive specimens
with the 2nd specimen also positive by culture), and uninfected (2
consecutive negative PCR results). Consecutive positive PCR tests were
by themselves not specific. DISCUSSION AND CONCLUSIONS: In HIV- exposed
infants, infection status can be efficiently determined by age 3 mo.,
utilizing a combination of PCR and culture assay results. Immunologic
assessment and virus load estimation to correlate with disease
progression are ongoing.
