born with SCD2
Although more people in the US are living with SCD than with other genetic conditions, such as cystic fibrosis (~30,000 people) or hemophilia (~20,000 people), they have considerably less access to comprehensive coordinated care.6-8
While there are extensive networks of multidisciplinary specialty centers for both cystic fibrosis and hemophilia, there is no comparable national network of treatment centers for SCD.8
of people with SCD usually receive their care in the emergency room setting, which can lead to inefficient and suboptimal management of their chronic condition.9,10
Genotype | Prevalence | >3 pain episodes | Leg ulcers | Hb g/dL | LDH U/L |
---|---|---|---|---|---|
HbSS (sickle cell anemia) | ~75% | 31% | 22% | 8.6 | 437 |
HbSC | ~18% | 28% | 9% | 11.6 | 245 |
HbSβ+-thalassemia | ~4% | 26% | 11% | 11.1 | 245 |
HbSS = hemoglobin SS; HbSC = hemoglobin SC; HbSβ+-thalassemia = hemoglobin Sβ+-thalassemia; Hb = hemoglobin; LDH = lactate dehydrogenase
The National Heart, Lung, and Blood Institute has developed comprehensive, evidence-based guidelines for the diagnosis and management of sickle cell disease
American Society of Hematology developed clinical practice guidelines on the management of sickle cell disease
A library of useful links to sickle cell disease resources for providers
From the Centers for Disease Control and Prevention (CDC), this resource directory lists sickle cell disease national agencies, specialty care centers, and community-based organizations
Sponsored by the Emory School of Medicine, this online center highlights the latest clinical updates in sickle cell disease and webinars, as well as personal narratives from people impacted by SCD
