Insights
Children with sickle cell disease (SCD) and acute chest syndrome (ACS) showed a higher frequency of asthma. This suggests a potential link between asthma and ACS in pediatric SCD patients.
Area of Science:
- Pediatric Hematology
- Pulmonology
- Genetics
Background:
- Acute chest syndrome (ACS) is a severe complication in sickle cell disease (SCD).
- Understanding risk factors for ACS in children with SCD is crucial for early intervention.
Purpose of the Study:
- To determine the frequency of asthma in children diagnosed with SCD and ACS.
- To investigate if asthma is more common in pediatric SCD patients who develop ACS.
Main Methods:
- Retrospective chart review of 60 children (1.5-17 years) with SCD and ACS (1997-2002).
- Statistical analysis (cross-tabs, t-tests) used to assess asthma occurrence significance.
Main Results:
- 53% (32/60) of children with SCD and ACS had pre-existing asthma or abnormal pulmonary function.
- This indicates a notable prevalence of asthma in this cohort prior to ACS.
Conclusions:
- This study is the first to report an increased frequency of asthma preceding ACS in pediatric SCD patients.
- A small sample size and single-center design may limit generalizability.
Introduction:
Acute chest syndrome (ACS) is a potential life-threatening complication of sickle cell disease (SCD). The purpose of this study was to identify the frequency of asthma in children with SCD who were diagnosed with ACS. The objective was to determine if an increased frequency of asthma exists in children with SCD and ACS.
Method:
A retrospective descriptive chart review covering the period from June 1997 to June 2002 was conducted on 60 children ranging in age from 1.5 years to 17 years who had SCD and ACS. Cross-tabs analysis and student t tests were used to determine the significance of the occurrence of asthma in children in whom ACS developed.
Results:
Of the 60 eligible children with SCD, 53% (32/60) had asthma and/or abnormal pulmonary function tests prior to the development of ACS.
Discussion:
This is the first study to report a slight increase in the frequency of asthma prior to the initial ACS in children with SCD. The small convenience sample size from one center may have been a limitation in this study to detect significant differences between the variables.

01:20Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
