Paroxysmal nocturnal hemoglobinuria (PNH) is a chronic, multi-systemic, progressive and life-threatening disease characterized by intravascular hemolysis, thrombotic events, serious infections and bone marrow failure.1, 2Hemolysis in PNH is due to the action of the complement on abnormal red blood cells (RBCs).
