Parvovirus B19 infection and anemia after kidney transplantation: a report of two cases
Tóm tắt
Post-transplantation anemia is common among renal transplant recipients (RTR). The most frequent causes are erythropoietin deficiency, acute allograft rejection, iron deficiency, hemolytic anemia, adverse effects of immunosuppressive therapy, and virus infection. Human parvovirus B19 (HPV B19) can cause persistent viremia and erythropoietin-resistant erythroid aplasia in immunosuppressed patients. This case report describes two male renal transplant recipients who infected HPV B19 after kidney transplantation with severe anemia. Rapid and severe anemia that did not respond to blood transfusion. Adjustment of immunosuppressive drugs and intravenous immunoglobulin treatment resolved severe anemia after two months. In conclusion, when anemia develops rapidly and severely in renal transplant recipients in the absence of rejection and hemolysis, parvovirus B19 infection should be considered.
