Independent Association of Serum IgA Levels with Moderate-to-Severe Obstructive Sleep Apnea in Children with Adenotonsillar Hypertrophy
To investigate the association between serum immune markers and the severity of obstructive sleep apnea (OSA) in children with adenotonsillar hypertrophy (ATH) and to develop a multivariate diagnostic model.
Key Findings:
Moderate-to-Severe OSA group had significantly lower lowest oxygen saturation (LSpO2) and larger adenoids compared to Mild/No OSA group.
Serum IgA levels were significantly elevated in the Moderate-to-Severe OSA group.
Multivariate logistic regression identified LSpO2 as a protective factor and IgA as an independent risk factor for moderate-to-severe OSA.
Interpretation:
Elevated serum IgA levels indicate a potential role of chronic mucosal inflammation in the severity of OSA in children with ATH, distinct from allergic mechanisms.
Limitations:
Cross-sectional design limits causal inferences.
Sample size may affect the generalizability of results.
Conclusion:
Elevated serum IgA is independently associated with moderate-to-severe OSA in children with ATH, and a combined diagnostic model offers high diagnostic value.
