Sickle Cell Disease: A Primer for Primary Care Providers

Area of Science:

• Genetics and Hematology
• Pediatric Medicine
• Global Health

Background:

• Sickle cell disease (SCD) is an autosomal recessive disorder with a significant global health burden.
• It involves dysfunctional hemoglobin leading to erythrocyte sickling, hemolysis, and inflammation.
• SCD causes end-organ damage, unique risks, and long-term complications.

Purpose of the Study:

• To review the current understanding of sickle cell disease.
• To discuss the established and emerging treatment options for SCD.
• To highlight the clinical implications and management of SCD.

Main Methods:

• Literature review of sickle cell disease pathophysiology, clinical manifestations, and treatment.
• Analysis of the efficacy of hydroxyurea in managing SCD.
• Overview of novel and curative therapies in development.

Main Results:

• Hydroxyurea is the most established treatment, reducing vaso-occlusive crises and preserving organ function in SCD patients.
• Emerging disease-modifying and curative therapies show promise for substantial future impact.
• Understanding SCD's complexities is crucial for effective patient care.

Conclusions:

• Sickle cell disease requires comprehensive management strategies.
• Hydroxyurea remains a cornerstone therapy for SCD.
• Advancements in SCD treatment offer hope for improved patient outcomes.
