Study Summary

In this prospective observational trial, participants with chronic hemolysis will be assessed with echocardiogram for elevated tricuspid jet velocity and other evidence of pulmonary hypertension. Participants will have laboratory studies evaluating: severity of hemolysis, splenic function, inflammation, endothelial dysfunction, and hypercoagulability. There will be 3 main categories of participants enrolled in this study: (1) pediatric participants with severe sickle cell disease (SCD) (HbSS, HbS/β° thalassemia ) who are not receiving treatment (e.g., hydroxyurea or chronic transfusions); (2) pediatric participants with other forms of SCD or severe SCD (HbSS, HbS/β° thalassemia) patients being treated with hydroxyurea or chronic transfusions; and (3) pediatric and adult participants with other non-sickling hematological disorders.
