Hemoglobin S polymerization: primary determinant of the hemolytic and clinical severity of the sickling syndromes.


We examined the extent to which the intracellular polymerization of sickle hemoglobin (HbS) can account for the severity of anemia and of vaso-occlusive manifestations in the various sickling syndromes. Polymer formation in sickle cell disease depends principally on the intraerythrocytic hemoglobin composition and concentration. In our studies, the polymer… (More)
