Parvovirus B19 infection in pediatric solid-organ and bone marrow transplantation.
The clinical significance of parvovirus B19 infection in pediatric solid-organ and bone marrow transplanted patients is unclear. The overall prevalence of parvovirus B19 infection in these patients is about 1-2% during the first year after transplantation. The most common symptom is anemia, but leukopenia and thrombocytopenia have also been observed. Rare cases of hepatic dysfunction, myocarditis, vasculitis and respiratory failure have also been reported. Whereas serology is of limited value around the time of transplantation, it is recommended that a search for B19 DNA is included in first-line investigations in any transplanted patient with unexplained anemia. Specific antiviral therapy is not available, however, intravenous immunoglobulin produces rapid improvement in most cases. Although relatively rare, the severe complications following parvovirus B19 infection in the transplant setting can be avoided by early diagnosis and treatment.
