Clearance of HIV infection in 12 perinatally infected children: clinical, virological and immunological data.

Abstract

In our cohort, we showed that an unexpected number of children born to HIV-seropositive mothers (6.7%) cleared HIV infection during the first year of life, and subsequently became seronegative. Interestingly, most of these children exhibited unspecified clinical signs during the first months of life. Five of these children were tested positive only by PCR, which suggests a low virus load and could, at least partly, explain spontaneous clearance. However, 4 years later, among the seven remaining infants, two seronegative children presented recurrent hepatosplenomegaly, which may indicate the presence of hidden virus not detectable by peripheral blood testing.
