Alpha-1 antitrypsin deficiency (AATD) is an autosomal co-dominant disease characterised by low serum levels of this molecule. Its epidemiology remains unknown in many countries, mainly due to its underdiagnosed state and lack of patients' registries. We aim to evaluate and characterise a sample of Portuguese individuals tested for AATD, between 2006 and 2015, based on a retrospective analysis from the database of a laboratory offering AATD genetic diagnosis service. 1684 individuals were considered, covering almost every region in Portugal...

Alpha 1 Antitrypsin (AAT) is a highly polymorphic serum protein. Several genetic variants are associated with varying degrees of decreased serum levels; however, these levels can rise in response to infection, inflammation, injury and estrogen levels. Although the effect of inflammation is well established, it has never been studied quantitatively with respect to specific genotypes in a large representative sample. Using data from a national AAT deficiency-targeted screening cohort, we evaluated AAT levels of patients with normal and deficiency genotypes in response to inflammation, indicated by elevated serum C-reactive protein (CRP)...

IL-6 and IL-33 are involved in the inflammatory process in obstructive lung diseases. In contrast to IL-6, few data on the expression of IL-33 in different biological samples from asthma and COPD patients are available. The aim was to evaluate the expressions of IL-33 and IL-6 in bronchial mucosa and to compare these expressions with the concentrations of both cytokines in various respiratory samples from patients with mild-to-moderate asthma and COPD. Serum, induced sputum and exhaled breath condensate IL-6 and IL-33 levels, as well as their expression in bronchial mucosa were evaluated in 22 asthma and 33 COPD patients...

The complexity of chronic obstructive pulmonary disease (COPD) can negatively impact the lives of people with the condition and compromise their capacity to take care of their needs. Unmet needs can then lead to significant morbidity, unpleasant emotional experiences and a poor quality of life; thus this systematic review aimed to identify, evaluate and synthesise the qualitative literature on the unmet needs of people with COPD. A qualitative meta-synthesis was performed according to the Joanna Briggs Institute method...

Patients with chronic obstructive pulmonary disease (COPD) show impairments in the autonomic nervous systems (ANS) function, which is responsible for cardiac autonomic regulation. This study assessed the autonomic function and cardio-vagal reactivity in conveniently sampled subjects with COPD participating in a pulmonary rehabilitation (PR) program. Twenty-six subjects with COPD and 22 age and gender matched control subjects were evaluated. R-R intervals were collected at rest in supine position. Thereafter, resting autonomic function parameters comprising linear and nonlinear analyses of heart rate variability (HRV) and baroreceptor sensitivity (BRS) were calculated...

The concept of asthma and COPD as separate conditions has been questioned, and the term asthma-COPD overlap syndrome has been introduced. We assessed the prevalence, symptoms, and lifestyle factors of asthma-COPD overlap (ACO) in a large Norwegian population-based study. From 2006 to 2008, a total of 50,777 residents of Nord-Trøndelag participated in the Nord-Trøndelag Health Study, Norway. They completed questionnaires regarding respiratory symptoms, disease status, and medication use. We estimated the prevalence and 95% confidence intervals of ACO...

High levels of psychological distress are documented in patients with COPD. This study investigates the extent to which patients with a high score on the Hopkins Symptoms Checklist-25 (HSCL-25) or with a high score on the Mental State scale of the Clinical COPD Questionnaire (CCQ) endorse a need for psychosocial care, and investigates several characteristics of patients with a need. Outpatients with COPD of the Department of Pulmonary Diseases of a University Medical Center were assessed with the HSCL-25, CCQ and a question on need for psychosocial care...

This randomised, open-label, cross-over, placebo-containing inhaler study assessed patient preference indicators for ELLIPTA and HandiHaler dry powder inhalers in patients with COPD (NCT02786927; GSK identifier: 204983). The primary objective of this study was to assess patient preference between ELLIPTA and HandiHaler based on the number of steps needed to use the inhaler. Eligible patients ≥40 years of age with COPD were randomised 1:1 to receive their current COPD medication plus a placebo-containing ELLIPTA or HandiHaler inhaler once daily for 7 ± 2 days (treatment period 1); this was followed by a 7 ± 2-day placebo treatment with the alternative inhaler...

In addition to dyspnea and fatigue, pain is a prevalent symptom in chronic obstructive pulmonary disease (COPD). Understanding the relative prevalence, magnitude, and interference with aspects of daily living of these symptoms can improve COPD management. Therefore, the purposes of this study were to: (1) compare the prevalence and magnitude of dyspnea, fatigue, and pain and how each limits aspects of daily living; (2) determine the association between pain and the other two symptoms; and (3) assess the impact of these symptoms on quality of life in COPD...

The interactions between obesity and chronic obstructive pulmonary disease (COPD) are being increasingly explored. In part, this is due to the globally increasing prevalence rates of obesity. The prevalence of obesity in COPD patients is variable, and it seems that obesity is more common in COPD patients compared with subjects who do not have COPD. However, further studies are encouraged in this area due to observed inconsistencies in the current data. In this review, we focus on the knowledge of the effects of obesity on dyspnea, pulmonary function, exercise capacity and exacerbation risk...

Triple inhaled therapy for chronic obstructive pulmonary disease (COPD) consists of an inhaled corticosteroid (ICS), a long-acting β2-agonist (LABA) and a long-acting muscarinic antagonist (LAMA) taken in combination. Triple therapy is recommended by the Global initiative for Chronic Obstructive Lung Disease (GOLD) for patients who experience recurrent exacerbations despite treatment with either a dual bronchodilator (preferred initial therapy) or LABA/ICS combination (alternative initial therapy). Although there is evidence for the greater efficacy of triple therapy compared with LABA/ICS and LAMA monotherapy with regards to improved lung function, health status, and exacerbation rate, the efficacy of triple therapy when compared with dual bronchodilation (LABA/LAMA) is as yet unknown...

Sputum and blood eosinophils are proposed as candidate biomarkers for the identification of chronic obstructive pulmonary disease (COPD) patients at risk for exacerbation and treatment response. In this study, we evaluated the associations of eosinophils with the presence of emphysema in COPD patients. Induced sputum and blood eosinophil measurements were performed in consecutive COPD patients. Patients underwent lung function testing and high resolution computed tomography (HRCT) of the chest and the presence of emphysema was quantified...

Nutritional abnormalities and physical inactivity are highly prevalent in patients with chronic obstructive pulmonary disease (COPD). The aim of this study was to determine the association between nutritional status/body composition and physical performance in patients with COPD. A cross-sectional observational study was conducted in outpatients with clinically stable, moderate to very severe COPD. In the assessment of nutritional status, we used dual energy X-ray absorptiometry, anthropometry, serum biomarkers, and the Mini-Nutritional Assessment (MNA) questionnaire...

Adherence to pulmonary rehabilitation (PR) is low. Previous studies have focused on clinical predictors of PR completion. We aimed to identify social determinants of adherence to PR. A cross-sectional analysis of a database of COPD patients (N = 455) in an outpatient PR program was performed. Adherence, a ratio of attended-to-prescribed sessions, was coded as low (<35%), moderate (35-85%), and high (>85%). Individual-level measures included age, sex, race, BMI, smoking status, pack-years, baseline 6-minute walk distance (6MWD: <150, 150-249, ≥250), co-morbidities, depression, and prescribed PR sessions (≤20, 21-30, >30)...

Human regulatory T cells (Tregs) have been reported to be not significantly different in the peripheral blood of patients with chronic obstructive pulmonary disease (COPD) and healthy controls. Recent research has identified some new markers for Tregs and indicated that Tregs are composed of distinct subpopulations. The aim of the study was to describe the changing patterns of circulating Treg subpopulations in patients with acute exacerbation of COPD (AECOPD) and healthy controls, and to explore their potential roles in AECOPD pathogenesis...

Chronic Obstructive Pulmonary Disease (COPD) is a major cause of morbidity and mortality worldwide. The Global Initiative for Chronic Obstructive Lung Disease (GOLD) project has been working to improve awareness, prevention and management of this disease. The aim of this study is to evaluate how COPD patients are reclassified by the 2017 GOLD system (versus GOLD 2011), to calculate the level of agreement between these two classifications in allocation to categories and to compare the performance of each classification to predict future exacerbations...

Chronic obstructive pulmonary disease (COPD) is a major cause of mortality worldwide, whose burden is expected to increase in the next decades, because of numerous risk factors, including the aging of the population. COPD is both preventable and treatable by an effective management including risk factor reduction, prevention, assessment, and treatment of acute exacerbations and co-morbidities. The available agents approved for COPD treatment are long-acting or ultra-long-acting β2-agonists (LABAs) and long-acting muscarinic antagonists (LAMAs) bronchodilators, as well as inhaled corticosteroids (ICS) in combination with LABAs...
