AB BACKGROUND: The early diagnosis of vertically transmitted human
immunodeficiency virus infection cannot be based on the presence of
specific serum antibodies since those of the maternal IgG class pass the
placenta and may be detected in children for up to 18 months. Based on
this fact, the aim of this study was to evaluate other techniques for
early diagnosis of the infection applicable from birth in 306 children
of infected mothers. METHODS: The production of in vitro antibodies,
virus culture and polymerase chain reaction (PCR) were used. The
sensitivity of the techniques was estimated in the 40 children diagnosed
with human immunodeficiency virus infection and specificity was
determined in the 266 uninfected children. RESULTS: The sensitivity for
the production of in vitro antibodies was 62.0% at 3 months and 94.7% at
6 months; 90.4% and 88.2%, respectively, for the viral culture and 92.3%
and 94.1%, respectively, for the PCR. The specificity of all the cases
was higher than 89.4% although varied in relation to age. CONCLUSIONS:
The combination of several diagnostic techniques provides better
performance for the early diagnosis of vertical transmission of the
human immunodeficiency virus. Given that viral culture takes longer to
provide results and is more expensive, it is less recommendable for
routine use, although the form of viral replication may be useful to
establish the prognosis.
