Abstract

Purpose

Sickle cell disease (SCD) imparts an increased risk for obstructive sleep apnea (OSA) in childhood. Studies of pediatric SCD have identified an increased risk for pain and neurologic complications with comorbid OSA. We determined the rate of a broad range of SCD-related medical complications to better characterize the spectrum of SCD complications related to OSA.

Methods

Retrospective chart review at a single hematology clinic identified 641 youth with SCD who received consistent screenings for OSA as part of routine hematological health maintenance visits over an 11-year period. Medical complication rates in the 136 children with OSA determined by polysomnography exams were compared to 136 matched controls at lower risk for OSA due to negative OSA screenings or exams.

Results

Children with SCD and OSA had higher overall rates of SCD complications than low OSA-risk controls; lung morbidity showed the largest effect size. Infection, cardiovascular, and neurologic complications occurred at higher rates in children with OSA. Children with comorbid OSA had higher rates of SCD complications both before and after OSA diagnosis.

Conclusions

OSA in children with SCD is associated with higher rates of a broad range of SCD complications, including pneumonia and acute chest syndrome. Routine screenings, diagnosis, and increased therapeutic intervention for children with comorbid OSA could decrease SCD morbidity.
