Parvovirus B19 is a single-stranded DNA virus that typically has an affinity for erythroid progenitor cells in bone marrow and leads to pure red cell aplasia. This is a common pathogen in humans, and the expression of the infection depends on the host's hematologic and immunologic status. Here, we report a female patient who developed severe and persistent anemia after kidney transplant while being on immunosuppressive therapy. The parvovirus B19 immunoglobulin M test was positive, and the virus was detected by polymerase chain reaction as parvovirus B19 (23.5 million copies/mL) in the blood sample. Bone marrow examination revealed giant pronormoblasts. She responded well to intravenous immunoglobulin without adverse event. Hemoglobin levels gradually increased, and normal levels were achieved at 3 months posttreatment. Although her renal function did not deteriorate, severe anemia (with hemoglobin level 5 g/dL) recurred 3 times during 12 months posttransplant.
