Telomere length and genetic variant associations with interstitial lung disease progression and survival.

ABSTRACT: Leukocyte telomere length (LTL), MUC5B rs35705950 and TOLLIP rs5743890 have been associated with idiopathic pulmonary fibrosis (IPF).In this observational cohort study, we assessed the associations between these genomic markers and outcomes of survival and rate of disease progression in patients with interstitial pneumonia with autoimmune features (IPAF, n=250) and connective tissue disease-associated interstitial lung disease (CTD-ILD, n=248). IPF (n=499) was used as a comparator.The LTL of IPAF and CTD-ILD patients (mean age-adjusted log-transformed T/S of -0.05±0.29 and -0.04±0.25, respectively) is longer than that of IPF patients (-0.17±0.32). For IPAF patients, LTL <10th percentile is associated with faster lung function decline compared to LTL ≥10th percentile (-6.43% p
