Study Summary

Sickle cell disease (SCD) is an inherited blood disorder that causes the red blood cells to change their shape from a round shape to a half-moon/crescent or sickled shape. Sickle-shaped cells can cause problems by getting stuck in blood vessels, blocking blood flow, and can cause inflammation and injury to important body parts. There are no specific treatments that improve this condition and promote blood flow hindered by sickle cell blockages. Another big challenge in managing sickle cell disease is that there are no good measures to determine changes and improvements in blood flow. Contrast-enhanced ultrasound is a technique currently used to detect blood flow in the heart, muscles, and other organs. It is extremely sensitive and can detect blood flow in the smallest of blood vessels. It would be very useful in helping healthcare providers know whether treatment strategies are improving blood flow during sickle cell blockages. The hypothesis is that contrast-enhanced ultrasound will be a feasible tool for determining changes in blood flow of subjects with sickle cell disease.

Primary Outcome

Primary outcome measure will be a 40% increase in skeletal muscle microvascular blood flow when 24 hour measurements are compared to baseline in subjects receiving Regadenoson. We took measurements in patients who received Regadenoson, as well as Sickle Cell controls. Both arms had microvascular blood flow (volume x velocity) measured at baseline and 24-hours, and those values were compared. A change ratio of \>1 means that the flow rate increased at 24 hours and a change ratio of \<1 means that
