Ivacaftor for Chronic Obstructive Pulmonary Disease - Results from a Phase 2, Randomized Controlled Trial.
Patients with chronic obstructive pulmonary disease (COPD) exhibit acquired cystic fibrosis transmembrane conductance regulator (CFTR) dysfunction. CFTR modulators may improve outcomes in patients with COPD, although recent data regarding magnitude of benefit have been inconclusive and effects on mucociliary clearance are unknown. We conducted a phase 2, randomized, double blind placebo control trial to determine safety and tolerability, and explore the potential mechanism of ivacaftor for the treatment of COPD. ⋯ gov, ID: NCT03085485.

Epigenome-Wide Association Studies of COPD and Lung Function: A Systematic Review.
Rationale: Chronic obstructive pulmonary disease (COPD) results from gene-environment interactions over the lifetime. These interactions are captured by epigenetic changes, such as DNA methylation. Objectives: To systematically review the evidence form epigenome-wide association studies related to COPD and lung function. ⋯ A few genes (n = 123; 2.6%) were replicated in blood and respiratory samples, suggesting that blood can recapitulate some changes in respiratory tissues. These findings have implications for future research. Systematic Review [protocol] registered with Open Science Framework (OSF).

Hospitalization Rates in Interstitial Lung Disease: An Analysis of the Pulmonary Fibrosis Foundation Registry.
Rationale: Little is known about hospitalization in other types of interstitial lung disease (ILD) besides idiopathic pulmonary fibrosis (IPF). Objectives: To determine the frequency of hospitalizations in various types of ILD and elucidate the association of hospitalization with outcomes. Methods: An analysis of the Pulmonary Fibrosis Foundation Patient Registry data was performed. ⋯ Conclusions: Rates of hospitalization are similar across ILD subtypes. The risk of death or transplant after posthospitalization is lower in patients with CTD-ILD and non-IPF IIP, compared with patients with IPF. In a mixed population of participants with ILD, all-cause hospitalizations were not associated with decreased transplant-free survival; however respiratory-related hospitalizations were.
