Serum eosinophil-derived neurotoxin: Correlation with persistent airflow limitation in adults with house-dust mite allergic asthma

摘要

Background: The serum level of eosinophil-derived neurotoxin (EDN), a protein present in eosinophil granules, correlates with the severity of childhood asthma. However, the relationship between the serum EDN level and the severity of adult asthma has not been sufficiently investigated.
