Paroxysmal nocturnal hemoglobinuria manifesting as hemolytic anemia with acute kidney injury

Abstract

Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired disorder characterized by low-grade, chronic hemolytic anemia accompanied by either thrombocytopenia or leukopenia with usually benign kidney involvement secondary to chronic tubular deposition of hemosiderin. Acute kidney injury (AKI) may be seen during hemolytic crisis. We report the case of a 45-year-old man with PNH who developed reversible AKI requiring temporary hemodialysis support following herpes zoster infection.
