When did Sickle Cell Disease Association of America ( scdaa ) start?
Out of his pioneering efforts to advocate for the needs of people with sickle cell disease, the Sickle Cell Disease Association of America (SCDAA) was born. In 1960 Dr. Whitten started a fund to help minority medical students with financial and academic assistance. He wrote many educational materials and was the recipient of many honors and awards.
What is the life expectancy of someone with sickle cell disease?
Those cells can cause blockages of blood to organs and tissues, debilitating pain, and life-threatening complications. People with sickle cell disease have an average life expectancy of 40 to 60 years.
What is the survival rate of sickle cell anemia?
The one-year overall survival rate was 100%, and disease-free survival rate was 78%. The study shows that UCBT is able to cure children with severe SCD, greatly reducing the incidence and severity of chronic GVHD.

Can you die from sickle cell anemia?
