title: [Clinical aspects and complete blood counts in children exposed to HIV-1: comparison between infected patients and seroreverters]
abstract: OBJECTIVE: To analyze the evolution of clinical and hematological aspects of children exposed to the vertical transmission of HIV-1, comparing infected patients with uninfected ones or seroreverters. METHODS: Prospective, descriptive, longitudinal study. We analyzed 79 children born from HIV-1 infected mothers, under clinical follow up from March, 1996 until November, 1997, at the Immunodeficiency division of the Hospital de Clínicas da Unicamp (State University Hospital of Campinas). RESULTS: Failure to thrive was observed in both groups, but was greater among seroreverters. Among the infected children, 23 mothers did not use AZT during pregnancy, 16 of them (61.5%) had been breastfed, four were classified into clinical category N, seven into A and fifteen into B. Clinical manifestations in patients younger than one year were seen in 18 infected children (69.2%). Anemia was observed in 73.1% of the infected group and in 41.5% of the seroreverters (P<0.008). The comparison between the groups showed that the most common hematologic alterations in the infected children was microcytosis and hypochromia (P<0.05), lymphopenia between 15 and 18 months (P<0.05), monocytosis between 9 and 12 months (P<0.05) and a tendency towards high ferritin levels, with no statistical significance. CONCLUSIONS: Microcytic and hypochromic anemia were observed in both groups: iron deficiency in the uninfected children, and chronic disease anemia in the infected ones. The infected children presented with monocytosis and lymphopenia at an earlier stage.
