Acute Myeloid Leukemia and Fatal Scedosporium prolificans Sepsis After Eculizumab Treatment for Paroxysmal Nocturnal Hemoglobinuria: a Case Report

Eculizumab has become the standard of care for patients with paroxysmal nocturnal hemoglobinuria (PNH). As more patients are treated, the long-term outcomes of these patients will become apparent.

The possible effect of complement blockade is discussed
