Answer

The following statistics are available from the Centers for Disease Control and Prevention and the National Institutes of Health [15, 16] :

  • Sickle cell anemia is the most common inherited blood disorder in the United States
  • In the United States, approximately 100,000 people have SCD
  • SCD occurs in about 1 of every 16,300 Hispanic-American births
  • Approximately 1 in 13 black or African Americans has sickle cell trait

In the United States, SCD accounts for less than 1% of all new cases of end-stage renal disease (ESRD). [17] The following factors are known to portend a greater likelihood of progression to overt renal failure: hypertension, nephrotic-range proteinuria, hematuria, severe anemia, and a Central African Republic heritage. [18, 19, 20] In patients with SCD, 5-18% develop renal failure. [21] In one study cohort, the median age at the time of renal failure in patients with SCD was 23.1 years.
