This study aimed to evaluate maternal and fetal factors related to vertical transmission of HIV-1. Participants included 47 mother-child pairs. Behavioral, demographic, and obstetric data were obtained through interviews. Data related to delivery and newborns were collected from registries in the maternity hospitals. During the third trimester of pregnancy, CD4+ T lymphocytes and maternal viral load were measured. Mean age of the mothers was 25 years and 23.4% of the pregnant women were primigravidae. The most prevalent behavioral factor was lack of condom use. 48.9% of the women presented a CD4+ count greater than 500 cells/mm3, and 93.6% belonged to clinical category A. 95.7% of the women received zidovudine prophylaxis during pregnancy or childbirth, and the medication was also administered to all the neonates. 50.0% of patients were submitted to elective cesareans. Despite several risk and protective factors, none of the children was infected. Vertical transmission is an outcome of an imbalance among factors, with a predominance of risk over protective factors.
OBJETIVO: Descrição de caso de pneumonia redonda em criança. DESCRIÇÃO DO CASO: Criança do gênero feminino, quatro anos e 11 meses, com dor no corpo, cefaléia e febre sem sinais localizatórios há dois dias. Apresentou radiografia de tórax com imagem redonda em lobo superior do pulmão direito e lobo médio do pulmão esquerdo. O hemograma mostrou leucocitose e neutrofilia. Com a antibioticoterapia, houve resolução do quadro clínico e radiológico. COMENTÁRIOS: Considerando outros diagnósticos diferenciais diante desta apresentação radiológica, em crianças com quadro infeccioso, é razoável aguardar a resposta clínica à antibioticoterapia antes de prosseguir com investigação de maior complexidade.
