Abnormally Short Erythrocyte LifeSpan in Three Patients with Primary Myelofibrosis Despite Successful Control of Splenomegaly

Abstract

Splenectomy is an elective operation for refractory anemia in patients with primary myelofibrosis (PMF). We found that 3/3 patients with PMF in our department continued to have very shortened erythrocyte (RBC) lifespans (35 days, 66 days, and 37 days, respectively) after treatment-alleviated splenomegaly. These outcomes suggest that intravascular hemolysis predominantly independent of hypersplenism may underlie, at least to some extent, peripheral hemolysis in patients with PMF. More cases studies are needed to elucidate the role of splenomegaly in PMF-associated anemia.

Keywords: Hemolysis; Hypersplenism; RBC lifespan.
