Core Tip

Core Tip: This study presents a patient who developed human parvovirus (HPV) B19-associated acquired pure red cell aplasia (aPRCA) in the early postoperative period following simultaneous pancreas-kidney transplantation. Metagenomic next-generation sequencing (mNGS) was used to diagnose HPV B19 infection and the diminution in mNGS reads was correlated with hemoglobin and reticulocyte count improvements. Effective therapy included intravenous immunoglobulin infusion and adjustment of the immunosuppressive regimen. HPV B19-associated aPRCA should be considered when a patient experiences erythropoietin-resistant anemia and reticulocytopenia in the early postoperative period. Moreover, mNGS could be used for diagnosis and to reflect disease progression.
