Parvovirus B19 in anemic liver transplant recipients.
Five hundred thirty-three liver transplant recipients were seen for follow-up care over a 6-month period. Of these, 23 (4.3%) had a hemoglobin level of < or = 9 g/dl, with 19 being eligible for inclusion in this study. The median hemoglobin level was 8.7 g/dl. Two patients had iron-deficiency anemia. All of the patients were on therapeutic drugs which can suppress erythropoiesis or shorten the lifespan of mature erythrocytes. Six patients (31.6%) were viremic for human parvovirus B19 but none was B19 immunoglobulin M seropositive. Two patients were immunoglobulin M seropositive for cytomegalovirus. The patients with circulating B19 DNA were not easily distinguished from those without the virus by their laboratory results. The absence of reticulocyte counts for these patients contributed to this inability to differentiate B19 from other causes of anemia, particularly drug myelotoxicity. The high likelihood of making a specific diagnosis with the increasing availability of PCR should spur the search for this virus in the liver transplant population.
