Resolution of human parvovirus B19-induced nonimmune hydrops after intrauterine transfusion

Our objective is to report our experience with cases of prolonged recovery from nonimmune hydrops secondary to human parvovirus B19 infection occurring after intrauterine transfusion. We reviewed cases referred to our unit over a 10 year period for exposure to parvovirus B19 infection. Those cases w...

Description
Summary:Our objective is to report our experience with cases of prolonged recovery from nonimmune hydrops secondary to human parvovirus B19 infection occurring after intrauterine transfusion. We reviewed cases referred to our unit over a 10 year period for exposure to parvovirus B19 infection. Those cases with serologic evidence of recent infection were identified. The cases requiring intrauterine transfusion were reviewed for demographic details, time of exposure, parvovirus B19 serology, gestational age at detection of nonimmune hydrops, number and results of fetal blood samples, duration from intrauterine transfusion to resolution of hydrops, and neonatal outcome. Of 38 cases identified through serologic evidence of recent parvovirus B19 infection, 35 (92.1%) did not develop hydrops, and these were followed by serial ultrasonography for 8 weeks from the time of exposure. Three cases (7.9%) developed hydrops and required intrauterine transfusion; in two the transfusion was intravascular and in one it was intraperitoneal. The mean duration from intrauterine transfusion to resolution of hydrops was 8 weeks 2 days. Pregnancy outcome in all cases was normal. In cases of nonimmune hydrops secondary to parvovirus B19 infection, resolution of the hydrops after intrauterine transfusion may take up to 12 weeks with a normal pregnancy outcome.
