Desmosine and isodesmosine are products of elastin breakdown which are candidate biomarkers to measure lung destruction in COPD. Data exist on the burden of desmosines in urine and plasma in COPD but long-term changes have never been investigated. We determined the changes of desmosine levels over 14 months in urine and plasma of patients with type ZZ alpha-1-antitryspsin deficiency-related COPD. Urines and plasma for determination of desmosines were collected from 11 ex-smokers with moderate/severe emphysema at monthly intervals for 14 months.

Abstract
Desmosine and isodesmosine are products of elastin breakdown which are candidate biomarkers to measure lung destruction in COPD. Data exist on the burden of desmosines in urine and plasma in COPD but long-term changes have never been investigated. We determined the changes of desmosine levels over 14 months in urine and plasma of patients with type ZZ alpha-1-antitryspsin deficiency-related COPD. Urines and plasma for determination of desmosines were collected from 11 ex-smokers with moderate/severe emphysema at monthly intervals for 14 months.File in questo prodotto:
