Association of Serum Eosinophilic Cationic Protein With Disease Severity in Infant Bronchiolitis

Key Points

• Investigate the relationship between serum eosinophilic cationic protein levels and the severity of bronchiolitis in infants.
• Measured serum eosinophilic cationic protein levels in infants diagnosed with bronchiolitis.
• Classified cases based on severity and exposure to smoke.
• Analyzed correlations between ECP levels and clinical outcomes.
• Elevated serum ECP levels observed in severe bronchiolitis cases.
• ECP levels were higher in infants exposed to smoke.
• No evidence supporting ECP as a direct clinical risk stratification tool.
