P‐selectin expression was quantified as a binding index for platelet P‐selectin (the percentage of positive platelets multiplied by the mean fluorescence of positive platelets). 2020-07-01 Sickle cell disease (SCD) is the most common genetic hematologic disorder in the United States. The vaso-occlusive characteristics of SCD have been viewed historically as resulting from deformed red blood cells (RBCs) that mechanically obstruct capillaries to produce tissue hypoxia. 1 Present therapies for SCD are geared toward decreasing the concentration or polymerization rate of sickle 2017-12-14 2018-09-17 Data from a post hoc analysis of the phase II SUSTAIN study demonstrated that patients who receive crizanlizumab, a once-a-month, humanized anti-P-selectin monoclonal antibody infusion being investigated for the treatment of sickle cell disease, showed greater reductions of vaso-occlusive crises (VOCs) when they adhere to the treatment protocol, according to a presentation at the 2018 ASH Patients with sickle cell disease may experience pain crises related to P-selectin, which contributes to vaso-occlusion. Would an antibody that blocks bindin P-Selectin is found in the plasma of normal individuals at ng/mL concentrations.
