Summary of "Comparison of Serum Eosinophil-Derived Neurotoxin Levels between Wheezing and Non-wheezing Groups in Children with Respiratory Tract Infection."

: Eosinophil-derived neurotoxin (EDN) is associated with recurrent wheezing episodes after bronchiolitis, childhood asthma, and allergic rhinitis. We investigated if there is a measurable difference between serum EDN levels in children with wheezing and non-wheezing respiratory infections. : 171 children who visited a university hospital with respiratory infections were enrolled in the study. Subjects were divided into two groups: wheezing (n = 46) and non-wheezing (n = 125). Serum EDN levels were compared. : Serum EDN levels in the wheezing group were significantly higher than in the non-wheezing group (P < 0.001). The non-wheezing group was divided into three sub-groups: pneumonia, common cold, and tonsillitis. Serum EDN levels in the wheezing group were significantly higher than in the pneumonia, common cold, or tonsillitis subgroups (P < 0.001). There was no significant difference in serum EDN levels among the pneumonia, common cold, and tonsillitis subgroups. : These findings suggest that elevated serum EDN levels could be a distinctive feature of respiratory infections with wheezing. EDN's utility as a biomarker for wheezing-associated disease should be explored through further study.

A 19-kDa cationic peptide found in EOSINOPHIL granules. Eosinophil-derived neurotoxin is a RIBONUCLEASE and may play a role as an endogenous antiviral agent.

One of several basic proteins released from EOSINOPHIL cytoplasmic granules. Eosinophil cationic protein is a 21-kDa cytotoxic peptide with a pI of 10.9. Although eosinophil cationic protein is considered a member of the RNAse A superfamily of proteins, it has only limited RNAse activity.

An inherited autosomal dominant trait characterized by abnormally elevated levels of total serum THYROXINE; (T4) in euthyroid patients with abnormal SERUM ALBUMIN that binds T4 with enhanced affinity. The serum levels of free T4, free T3, and TSH are normal. It is one of several T4 abnormalities produced by non-thyroid disorder. This condition is due to mutations of the ALB gene on CHROMOSOME 4.
