BACKGROUND: Lung cancer is a leading cause of death and hospitalization for patients with chronic obstructive lung disease, (COPD); a detailed understanding of which clinical features of COPD increase risk is needed. METHODS: To identify clinical and imaging features of smokers, with and without COPD, that are associated with an increased risk of lung cancer, we performed a nested case-control study of COPDGene subjects with and without lung cancer, age 45-80, who smoked at least 10-pack years...

Surfactant proteins (SPs) have been studied in COPD patients as biomarkers of disease severity and as predictive factors of unfavorable outcomes. The aim of this exploratory study was to evaluate serum levels of SP-A, SP-B, SP-C, and SP-D in patients with COPD both during AECOPD and in stability and to test their possible associations with disease severity and with the development of new exacerbation events. 20 consecutive COPD patients hospitalized for AECOPD were included. Serum SP levels were measured on admission, at discharge, and on stability...

Chronic obstructive pulmonary disease (COPD) remains a common cause of morbidity and mortality worldwide. Patients with COPD and respiratory failure, whether acute or chronic have a poorer prognosis than patients without respiratory failure. Non-invasive ventilation (NIV) has been shown to be a useful tool in both the acute hospital and chronic home care setting. NIV has been well established as the gold standard therapy for acute decompensated respiratory failure complicating an acute exacerbation of COPD with reduced mortality and intubation rates compared to standard therapy...

BACKGROUND: The literature is scarce regarding the prevalence and clinical impact of IgG subclass deficiency in COPD. We investigated the prevalence of IgG subclass deficiencies and their association with exacerbations and hospitalizations using subjects from two COPD cohorts. METHODS: We measured IgG subclass levels using immunonephelometry in serum samples from participants enrolled in two previous COPD trials: Macrolide Azithromycin for Prevention of Exacerbations of COPD (MACRO; n = 976) and Simvastatin for the Prevention of Exacerbations in Moderate-to-Severe COPD (STATCOPE; n = 653)...

Background: To identify practices that do not add value, cause harm, or subject patients with chronic obstructive pulmonary disease (COPD) to a level of risk that outweighs possible benefits (overuse). Methods: A qualitative approach was applied. First, a multidisciplinary group of healthcare professionals used the Metaplan technique to draft and rank a list of overused procedures as well as self-care practices in patients with stable and exacerbated COPD. Second, in successive consensus-building rounds, description files were created for each "do not do" (DND) recommendation, consisting of a definition, description, quality of supporting evidence for the recommendation, and the indicator used to measure the degree of overuse...

Chronic obstructive pulmonary disease is predicted to become the 4th leading cause of death worldwide by 2030. The natural history of the disease includes progressive symptoms punctuated by acute exacerbations during which symptoms rapidly deteriorate. The resulting disability places significant burden on health and social care systems. Cough is the second most common symptom reported by COPD patients, is a source of significant distress and is associated with adverse outcomes. We discuss the importance of cough in COPD, its mechanism and the relationship between cough and COPD exacerbations...

Both asthma and COPD are complex, heterogeneous conditions comprising a wide range of phenotypes, some of which are refractory to currently available treatments. Elucidation of these phenotypes and identification of biomarkers with which to recognize them and guide appropriate treatment remains a priority. This review describes the utility of blood eosinophils as a surrogate biomarker of eosinophilic airway inflammation, a common feature of specific asthma and COPD phenotypes. The role of blood eosinophils in airway disease is described, as is their relevance in reflecting airway eosinophilia...

Chronic obstructive pulmonary disease (COPD) is a disabling condition that is characterised by poorly reversible airflow limitation and inflammation. Acute exacerbations of COPD are a common cause of hospitalisation and death among COPD patients. Several biochemical markers have been studied as outcome predictors in COPD; however, their measurement often requires significant time and resources. Relatively simple biomarkers of inflammation calculated from routine complete blood count tests, such as the neutrophil to lymphocyte ratio (NLR), might also predict COPD progression and outcomes...

Background: Many studies have found that YKL-40 may play an important pathogenic role in COPD. However, the results of these studies were inconsistent. Therefore, we performed a systematic review and meta-analysis to investigate the role of YKL-40 in COPD. Methods: We performed a systematic literature search in many database and commercial internet search engines to identify studies involving the role of YKL-40 in patients with COPD. The standardized mean difference (SMD) and Fisher's Z-value with its 95% confidence interval (CI) were used to investigate the effect sizes...

Gastroesophageal reflux disease (GERD) is associated with different pulmonary diseases, including chronic obstructive pulmonary disease (COPD). Whether GERD is contributory to COPD severity remains unclear. This study aims to evaluate the contribution of GERD to the clinical manifestation of COPD based on ventilatory parameters and yearly clinical exacerbations. We studied 48 patients (56% females, age 66 years) with COPD. All patients underwent high-resolution manometry and esophageal pH monitoring. The patients were separated into two groups according to the presence of GERD...
