简要总结
Sickle cell disease is characterized by chronic hemolytic anemia and blood rheological alterations. In addition, blood coagulation abnormalities have been reported in patients with sickle cell disease and hemolysis-derived products could be involved. The investigators hypothesized that patients with sickle cell disease and severe hemolysis (Lactate Dehydrogenase level > 484 IU/L) could have an increased risk of hypercoagulable state and subsequent thromboembolic complications.

主要结局
Overall coagulation activity
时间窗: Baseline
