ABSTRACT
Methoxy polyethylene glycol-epoetin beta (Mircera(R), Roche), a third-generation erythropoiesis-stimulating agent (ESA) is known as a continuous erythropoietin receptor activator (CERA). In patients with anemia associated with chronic kidney disease (CKD), it is administered intravenously or subcutaneously. Treatment-related adverse events induced by methoxy polyethylene glycol-epoetin beta occurred in 6%. Hypertension, diarrhea and nasopharyngitis were the most commonly reported adverse events. Cutaneous adverse reactions are rarely experienced with methoxy polyethylene glycol-epoetin beta including maculopapular eruption, facial erythema, and tinea pedis. To the best of our knowledge, no cases of leukocytoclastic vasculitis associated with methoxy polyethylene glycol-epoetin beta have ever been published in medical literature. Herein, we report on a case of leukocytoclastic vasulitis induced by methoxy polyethylene glycol-epoetin beta in a patient with anemia associated with chronic kidney disease.
