Analysis of Blood-based Biomarkers of Asthma
Completed
Conditions studied: Asthma
In brief
The purpose of this study is to analyze markers of inflammation in blood and in induced sputum for the purpose of identifying molecular markers of specific asthma phenotypes. The investigators' specific interest is demonstrating that periostin levels are higher than normal in blood. The investigators already have solid preliminary data to support this hypothesis, and our goal here is to replicate preliminary findings and extend them by examining further the characteristics of the asthma subgroup with elevated periostin levels.
