ABSTRACT

Human parvovirus B19 infection is known to be one of the causes of hydrops fetalis. The maternal infection caused by the virus may be symptomatic or asymptomatic. In this study, 40 pregnant women with gestational age of approximately 25 weeks, prenatal diagnosis of non immune hydrops fetalis and suspected of human parvovirus B19 infection were studied between January 1999 and December 2005. Serology results and detection of DNA in the maternal serum, foetal serum and amniotic fluid confirmed that 20 pregnant women had been infected by human parvovirus B19. The ultrasound examination demonstrated foetal hydrops, anaemia, hepatosplenomegaly, ascites, cardiopathy and amniotic fluid disorders. Among the positive cases, there were three fatal losses, one by miscarriage and two by intrauterine foetal death.


A infecção por parvovírus humano B19 é um dos responsáveis pela hidropsia fetal. A infecção materna causada pelo vírus pode ser sintomática ou assintomática. Neste estudo 40 mulheres com idade gestacional de aproximadamente 25 semanas, diagnóstico pré-natal de hidropsia fetal e suspeita de infecção por parvovírus humano B19 foram avaliadas durante o período de janeiro de 1999 a dezembro de 2005. Os resultados de sorologia e detecção de DNA no soro materno, fetal e fluido amniótico confirmaram 20 mulheres grávidas com infecção por parvovírus humano B19. A análise de ultra-som demonstrou hidropsia fetal, anemia, hepatosplenomegalia, ascite, cardiopatia e desordens amnióticas. Entre os casos positivos, ocorreram três perdas fetais: uma por aborto e duas por morte fetal intra-uterina.
