Understanding growth failure in children with homozygous sickle-cell disease

Area of Science:

• Pediatrics
• Genetics
• Hematology

Background:

• Sickle-cell disease (SCD) is a common genetic blood disorder in the U.S.
• Children with SCD exhibit impaired growth and delayed maturation, though the underlying reasons are not fully understood.
• Growth deviations in SCD typically emerge around six months after birth.

Purpose of the Study:

• To review existing literature on growth failure in children with sickle-cell disease.
• To elucidate the multifactorial pathophysiology contributing to growth deficits in pediatric SCD.
• To emphasize the importance of healthcare providers recognizing and managing SCD-related growth patterns.

Main Methods:

• Literature review of studies on pediatric sickle-cell disease and growth.
• Analysis of growth patterns from birth to identify divergence points.
• Synthesis of information regarding the pathophysiology of growth failure in SCD.

Main Results:

• Children with SCD show normal birth measurements, with growth divergence beginning around six months.
• Growth deficits in pediatric SCD are multifactorial.
• The clinical significance and consequences of these growth deficits are substantial.

Conclusions:

• Healthcare providers must be aware of the unique growth trajectories in sickle-cell disease.
• Early recognition of growth deviations is essential for clinical management.
• Further understanding of SCD pathophysiology can improve patient outcomes.
