Summary
Leptin levels are higher in children with asthma, particularly in boys. This suggests leptin may play a role in childhood asthma, potentially explaining its higher prevalence in males.
Area of Science:
- Pediatric Allergy and Immunology
- Endocrinology
- Respiratory Medicine
Background:
- Obesity is linked to asthma in children and adults.
- The role of leptin, an adipokine, in childhood asthma remains unclear.
Purpose of the Study:
- To investigate the relationship between leptin and asthma parameters in children.
- To explore leptin's association with atopy and pulmonary function in pediatric asthma.
Main Methods:
- Serum leptin levels and body mass index (BMI) were measured in 102 asthmatic and 33 healthy children.
- Skin prick tests, total serum IgE, and pulmonary function tests were conducted.
- Logistic and multiple regression analyses were used to assess predictors of asthma and leptin levels.
Main Results:
- Asthmatic children had significantly higher serum leptin levels than healthy children (P=.008).
- Elevated leptin levels in asthmatic children were primarily observed in boys (P=.003).
- Leptin was a significant predictor of asthma (odds ratio, 1.98; P=.021), while sex, age, and BMI were also significant factors affecting leptin levels.
Conclusions:
- Leptin may play a role in the pathogenesis of atopic asthma.
- Higher serum leptin levels in asthmatic boys could contribute to the greater prevalence of childhood asthma in males.
