Recurrent anemia in kidney transplant recipients with parvovirus B19 infection.

Parvovirus B19 (PV B19) infection is known to cause acute anemia in solid organ transplant recipients. Intravenous immunoglobulin combined with reduction of immunosuppression may be of benefit to clear the infection. However, PV B19-associated anemia can be recurrent. We describe three renal transplant recipients with a PV B19 infection. These patients showed recurrent anemia with episodes separated by as much as several months.
