Factors Associated With Elevated Exhaled Nitric Oxide Fraction in Infants With Recurrent Respiratory Symptoms

Abstract

A Kotaniemi-Syrjanen, LP Malmberg, K Malmstrom, AS Pelkonen, MJ Makela. Eur Respir J. 2013;41(1):189–194 To evaluate the relationship between exhaled nitric oxide fraction (FeNO) and increased airway responsiveness, and to clarify whether there are any associations between these measures and risk factors for respiratory morbidity in infants with recurrent lower respiratory tract symptoms. Studied subjects were 444 children aged <3years with recurrent lower respiratory tract symptoms including wheeze, dry or productive cough, and/or shortness of breath. Subjects were assessed for FeNO, lung function tests, and the …
