Serum levels of periostin and exercise-induced bronchoconstriction in asthmatic children

Periostin is induced by IL-13 and has been studied as a biomarker of asthma. The present study explored the relationship between serum levels of periostin and exercise-induced bronchoconstriction (EIB) in asthmatic children.The study population consisted of 86 children 6-15 years old divided into an asthmatic group (n = 56) and healthy controls (n = 30).
