Anti-Erythropoietin Antibody-Mediated Pure Red Cell Aplasia
摘要
The wide application of recombinant human erythropoietin (r-HuEPO) among the patients with chronic kidney disease (CKD) can bring about a rare but sever complication called anti-EPO antibody mediated pure red cell aplasia (PRCA). Once diagnosed, r-HuEPO administration should be discontinued immediately. However, after the removal of the anti-EPO antibody, it is still difficult for us to choose a nephrogenic anemia treatment for these CKD patients as restarting r-HuEPO therapy risks the recurrence of anti-EPO antibody mediated PRCA. A 78-year-old man with end-stage renal disease received r-HuEPO who developed anti-EPO PRCA unfortunately and his haemoglobin dropped continuously. During the removal of antibodies by treatment with corticosteroids and cyclosporine, therapy for nephrogenic anemia with roxadustat was prescribed at the meantime which led to a satisfactory result. Roxadustat is a kind of oral Hypoxia-inducible factor-Prolyl hydroxylase inhibitor which is developed for anemia treatment. This case reveals the potential effect of Roxadustat on anti-EPO PRCA.
