Relevance of serum ECP measurements for monitoring acute asthma in children.
To evaluate the role of serum eosinophil cationic protein (ECP) concentration as a monitoring parameter in acute bronchial asthma, 11 children (mean age 10.2 years) were studied during an acute exacerbation of their disease. Under an appropriate anti-inflammatory therapy, FEV1 increased significantly at day 1 (p < 0.05), day 14 (p < 0.05), day 28 (p < 0.03), and day 56 (p < 0.03) compared to baseline values at referral to hospital. Serum ECP concentration decreased in the group of patients significantly at day 28 (p < 0.02) and day 56 (p < 0.04). However, considering the individual serum ECP time courses, most of the patients did not show a uniform pattern of continuously decreasing values. From our data, we conclude that measuring serum ECP concentration during acute asthma episodes in children may play a role in some patients, whereas in others--probably those without acute eosinophil inflammation--monitoring by serum ECP concentration is of limited value.
