Chronic obstructive pulmonary disease (COPD) is characterized by progressive pulmonary and systemic inflammation. Acute exacerbations of COPD (AECOPD) are associated with acute inflammation and infections and increase the rates of morbidity and mortality. Currently, neither the aetiology nor pathogenesis of AECOPD are entirely understood. Exosomes have been reported to regulate immunity and inflammation via specific intercellular communications through an array of macromolecules (e.g. microRNA and proteins) contained within these microvesicles...

BACKGROUND: The impact of pulmonary hypertension (PH) in chronic obstructive pulmonary disease (COPD) on survival after lung transplantation (LTx) is not known. MATERIAL AND METHODS: First-time adult LTx recipients with COPD transplanted between May 2005 and September 2013 were identified in the United Network for Organ Sharing Registry database, and tracked from transplant date until death or censoring. Right heart catheterization (RHC) measurements at time of wait listing were used to predict all-cause mortality after LTx, with multivariable analyses stratified by transplant type...

RATIONALE: Anti-aminoacyl transfer RNA synthetase antibodies (anti-ARS) are a group of myositis-specific autoantibodies that are detected in the sera of patients with polymyositis and dermatomyositis (PM/DM) and also in those of patients with idiopathic interstitial pneumonias without any connective tissue disease (CTD), including PM/DM. Although we reported the clinical characteristics of interstitial lung disease with anti-ARS antibodies (ARS-ILD) with and without PM/DM, the long-term prognosis of ARS-ILD remains undetermined...

OBJECTIVE: Small fiber neuropathy commonly affects patients with sarcoidosis and is often refractory to standard immunosuppressive therapies used for systemic disease. The clinical features of sarcoidosis-associated small fiber neuropathy (SSFN) and its response to medical therapy have not been described in a large population. METHODS: We performed a retrospective review of patients with SSFN seen at the Cleveland Clinic over a 4-year period. RESULTS: SSFN was identified in 143 individuals although other causes of neuropathy were found in 28 cases...

BACKGROUND: The need for additional research on symptomatic smokers with normal spirometry has been recently emphasized. Albeit not meeting criteria for Chronic obstructive pulmonary disease (COPD) diagnosis, symptomatic smokers may experience activity limitation, evidence of airway disease, and exacerbations. We, therefore, evaluated whether symptomatic smokers with borderline spirometry (post-bronchodilator FEV1/FVC ratio between 5th to 20th percentile of predicted values) have pulmonary function abnormalities at rest and ventilatory constraints during exercise...

BACKGROUND: Rheumatoid arthritis-associated interstitial lung disease (RA-ILD) is associated with significant morbidity and mortality. Similarities have been observed between patients with idiopathic pulmonary fibrosis (IPF) and the UIP (usual interstitial pneumonia) form of RA-ILD. The GAP (gender, age, physiology) model has been shown to predict mortality in patients with IPF, but its ability to predict mortality in RA-ILD is not known. METHODS: We identified 309 patients with RA-ILD at 4 academic centers with ongoing longitudinal cohorts of patients with ILD...

BACKGROUND: To assess the level of asthma control achieved with budesonide/formoterol in Chinese patients with asthma, based on the Global Initiative for Asthma (GINA) definition and Asthma Control Test (ACT) score. METHODS: This multicenter, cross-sectional study (NCT01785901) evaluated asthma control levels in Chinese patients receiving physician-prescribed budesonide/formoterol treatment. Adults with a diagnosis of asthma ≥6 months and receiving budesonide/formoterol treatment ≥3 months before screening were consecutively enrolled...

BACKGROUND: Chronic cough is commonly associated with asthma, gastro-oesophageal reflux disease and postnasal drip, but in a significant proportion, no associated cause can be found. We determined whether examination of bronchial biopsies would be useful in determining the cause associated with chronic cough. METHODS: 100 consecutive patients referred to a specialist cough clinic underwent a systematic assessment including a fiberoptic bronchoscopy for bronchial biopsies...

BACKGROUND: Systemic inflammation in bronchiectasis is poorly studied in relation to aetiology and severity. We hypothesized that molecular patterns of inflammation may define particular aetiology and severity groups in bronchiectasis. METHOD: We assayed blood concentrations of 31 proteins from 90 bronchiectasis patients (derivation cohort) and conducted PCA to examine relationships between these markers, disease aetiology and severity. Key results were validated in two separate cohorts of 97 and 79 patients from other centres...

BACKGROUND: Psychological stress has long been suspected to have a deleterious effect on asthma, with acute psychological stress being associated with physiological responses in asthma patients. OBJECTIVES: The purpose of this systematic review was to provide a narrative synthesis of the impact of acute laboratory psychological stress on physiological responses among asthma patients. METHODS: An extensive search was conducted by two independent authors using Pubmed, PsycINFO, PsyArticles and the Cochrane Library electronic databases (up to September 2016)...

BACKGROUND: Acute bronchodilator response (BDR) is a potential phenotypic characteristic of COPD. However, the clinical factors associated with BDR in patients with COPD remain unclear, particularly for BDR to anticholinergic agents. OBJECTIVES: We aimed to clarify the clinical factors associated with BDR to β2-agonist and/or anticholinergic agent, considering time-associated variations of BDR. We also evaluated the association between BDR and clinical course of COPD...

RATIONALE: Health-related quality of life (HRQL) is impaired among patients with interstitial lung disease (ILD). Little is understood about HRQL in specific subtypes of ILD. OBJECTIVES: The aim of this study was to characterize and identify clinical determinants of HRQL among patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) and compare them to patients with idiopathic pulmonary fibrosis (IPF). METHODS: We identified patients with a diagnosis of RA-ILD and IPF from an ongoing longitudinal cohort of ILD patients...

BACKGROUND: Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) is a rapid and ultimately fatal condition, and no effective treatment has been established. Pirfenidone has antifibrotic effects in IPF; however, its efficacy for AE-IPF is unclear. OBJECTIVES: To evaluate the efficacy of pirfenidone for AE-IPF. METHODS: We retrospectively reviewed the medical records of 135 IPF patients treated during the period from April 2008 to April 2015 and identified and extracted 47 AE-IPF patients (42 men, 5 women; mean age, 73...
