SO Int Conf AIDS. 1994 Aug 7-12;10(1):310 (abstract no. PC0168). Unique Identifier : AIDSLINE ICA10/94370165 AB OBJECTIVE: To describe and to evaluate results obtained in our Laboratory from serum samples of infants born from seropositive mothers in Buenos Aires, Argentina. METHODS: 18 month follow-up using serological techniques: EIA or PA--WB and EIA(Ag)--HIV antigen confirmation. Licensed kits were used. RESULTS: 489 serum samples of 306 infants born from HIV seropositive mothers were received from Jan. 1989 through Dec. 1993 (1989 = 32, 1990 = 43, 1991 = 66, 1992 = 88, 1993 = 77). 69 (22.5%) have completed the follow-up; 30 of them (43.5%) remained seropositive, 32 (46.4%) seroreverted, and 7 (10.1%) were undetermined (p-24 band was still present after long term follow-up). 52 infants are still under follow-up. 169 (55.4%) were lost and their present status is unknown; 42 were HIV+ at first sample, presenting clinical symptoms of AIDS while their mothers' HIV+ status were unknown; 31 were elder than 18 months, and 11 were under 12 months, being serological diagnosis very difficult due to total or partial lose of HIV specific antibody. CONCLUSION: 1) hard policies and social service are needed for these infants' families to lead an adequate clinical and serological follow-up. 2) Early detection of perinatal HIV acquired infection is needed to establish the specific therapy as soon as possible.
