AB OBJECTIVE: Increased morbidity has been described in non-infected
children born to HIV infected mothers. CD4 immunosuppression have also
been reported and attributed to drug use during pregnancy. This study
investigates immunosuppression and clinical features in a subgroup of
non-infected children born to HIV infected mothers. METHODS: From 1981
to 1994, 157 children born to HIV infected mothers were followed; 69 are
infected, 70 non-infected and 18 undeterminate. Blood samples were
obtained at 3 month intervals. Fluorescent microscopy and later flow
cytometry were used in a double antibody technique with monoclonal
antibodies (BD). HIV-1 antibodies were tested by ELISA, confirmed by
RIPA. HIV diagnosis was confirmed by HIV culture and PCR since 1988.
Clinical status was evaluated at each visit. RESULTS: 63/70 children who
seroreverted had normal immunological parameters over time in a follow
up of a mean 84 months (6 to 120 months). Clinically none of these
children had clinical features compatible with AIDS defining events.
Many minor clinical problems were noted. 7/70 children had sustained or
recurrent immunosuppression over time. 4/7 had a persisting low CD4. 3/7
patients had recurrent low CD4 count (below 500/mm3) over 7 years of
follow up. 4/7 were twins. None of these children developed symptoms
compatible with AIDS. HIV ELISA were repeatedly negative after 7 years.
HIV culture and PCR were negative in all. None of these children were
born to IDU mothers. CONCLUSION: In 10% of 70 seroreverted children,
persisting CD4 lymphopenia is noted without detectable HIV. A sub group
of children born to HIV infected mothers seems to sustain unexplained
immunological injury.
