Eligibility Criteria

Age18 Years - 50 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)
Men and women, ages 18 to 50, who had at least three emergency room visits or hospitalizations for sickle cell anemia during the year prior to recruitment. Patients with greater than 20 crises per year were included. A total of 295 patients had Hb ss and four had Hb SB thalassemia.
