Study of Beet Juice for Patients With Sickle Cell Anemia
Phase 2 Study of Effects of Plasma Nitrite in Sickle Cell Anemia

Brief Summary
The investigators hypothesize that increasing plasma nitrite using dietary nitrate will improve platelet function and red cell deformability and decrease MCHC in patients with sickle cell disease. The investigators will test this hypothesis through administration of daily intake of beetroot juice (Unbeetable - Performance Drink) to patients with sickle cell disease for 28 days. The investigators will evaluate the safety of daily beet root juice intake in patients with sickle cell disease. In addition, the investigators will measure MCHC, red cell deformability, and platelet function (activation and aggregation) in response to daily intake of beet root juice in this patient population.

Study Arms (1)
Beet Juice
EXPERIMENTALVolunteers will drink a single 8 ounce bottle of beet juice (Unbeetable) per day for 28 days. On days 1,14, and 28, the juice will be drunk just prior to having blood drawn. Blood will also be drawn 1.5 hours after drinking the juice on days 1,14, and 28.
Interventions
Volunteers will drink a single 8 ounce bottle of beet juice (Unbeetable) per day for 28 days. On days 1,14, and 28, the juice will be drunk just prior to having blood drawn. Blood will also be drawn 1.5 hours after drinking the juice on days 1,14, and 28.
