Abstract [en]

Background: Periostin has been suggested as a novel, phenotype-specific biomarker for asthma driven by type-2 inflammation. However, large studies examining relationships between circulating periostin and patient characteristics are lacking and the suitability of periostin as a biomarker in asthma remains unclear.

Aim: To examine circulating periostin in healthy controls and subjects with asthma from the general population with different severity and treatment profiles, both with and without chronic rhinosinusitis (CRS), in relation to other biomarkers and clinical characteristics.

Methods: Serum periostin was examined by ELISA in 1091 subjects aged 17-76 from the Swedish GA(2)LEN study, which included 460 asthmatics with/without chronic rhinosinusitis (CRS), 97 individuals with CRS only, and 203 healthy controls. Clinical tests included measurement of lung function, FeNO, IgE, urinary eosinophil derived neurotoxin (U-EDN) and serum eosinophil cationic protein (S-ECP), as well as completion of questionnaires regarding respiratory symptoms, medication and quality of life.

Results: Although median periostin values showed no differences when comparing disease groups with healthy controls, multiple regression analyses revealed that periostin was positively associated with higher FeNO, U-EDN and total IgE. In patients with asthma, an inverse relationship with lung function was also observed. Current smoking was associated with decreased periostin levels, whereas increased age and lower BMI related to higher periostin levels in subjects both with and without asthma.

Conclusion: We confirm associations between periostin and markers of type-2 inflammation, as well as lung function, and identify novel constitutional factors of importance to the use of periostin as a phenotype-specific biomarker in asthma.
