Chronic obstructive pulmonary disease (COPD) is currently the fourth leading cause of death in the world and its incidence and prevalence is on the rise. It is evident that COPD is linked to cardiovascular disease. In the last years, several studies demonstrated that COPD may also be a risk factor for stroke, another major cause of death worldwide. Taking in consideration that COPD has multiple comorbidities it is hard to say whether COPD is an independent risk factor for stroke or it is due to confounding effect...

The binary approach to the diagnosis of Chronic Bronchitis (CB) is a major barrier to the study of the disease. We investigated whether severity of productive cough can be graded using symptoms and presence of fixed airflow obstruction (FAO), and whether the severity correlates with health status, exposures injurious to the lung, biomarkers of inflammation, and measures of airway wall thickening. Findings from a cross-sectional sample of 1,422 participants from the Lovelace Smokers Cohort (LSC) were validated in 4,488 participants from the COPDGene cohort (COPDGene)...

Chronic obstructive pulmonary disease (COPD) mortality based on the underlying cause of death (UCOD) underestimates disease burden. We aimed to determine the current COPD mortality rate, trends and the distribution of co-morbidities using United States (US) multiple-cause of death (MCOD) records. All 38,905,575 death certificates of decedents aged ≥45 years in the United States were analyzed for 1999-2015. COPD was defined by ICD-10 codes J40-J44 and J47 based either on the UCOD or up to 20 contributing causes coded...

The development of COPD features, such as an incomplete reversibility of airway obstruction (IRAO), in smoking or non-smoking asthmatic patients, a condition often named Asthma-COPD Overlap (ACO), has been recognized for decades. However, there is a need to know more about the sub-phenotypes of this condition according to smoking. This study aimed at comparing the clinical, physiological and inflammatory features of smoking and non-smoking asthmatic patients exhibiting IRAO. In this cross-sectional study, patients with an IRAO with (ACO, ≥20 pack-years) or without (NS-IRAO, <5 pack-years) significant smoking history completed questionnaires about asthma control (ACQ, score 0-6, 6 = better score) and quality of life (AQLQ, score 1-7, 1 = better score) and performed expiratory flows, lung volume and carbon monoxide diffusion capacity measurements...

Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease associated with significant morbidity and mortality. Current diagnostic criteria based on the presence of fixed airflow obstruction and symptoms do not integrate the complex pathological changes occurring within the lung and they do not define different airway inflammatory patterns. The current management of COPD is based on 'one size fits all' approach and does not take the importance of heterogeneity in COPD population into account. The available treatments aim to alleviate symptoms and reduce exacerbation frequency but do not alter the course of the disease...

Early detection of treatment response is important in the long-term treatment and management of patients with chronic obstructive pulmonary disease (COPD). This analysis evaluated whether early improvement in symptoms, recorded in the first 7 or 14 days via an electronic diary (eDiary) compared with baseline, can predict clinically meaningful treatment responders at 12 weeks. CRYSTAL was a 12-week, randomized, open-label study that demonstrated the increased effectiveness of indacaterol/glycopyrronium (IND/GLY) or glycopyrronium (GLY), after a direct switch from on-going baseline therapies, in patients with symptomatic COPD and moderate airflow obstruction...

Comparisons between endurance and strength training in chronic obstructive pulmonary disease (COPD) patients have produced equivocal findings when examining physical function and health-related quality of life (HRQL). One reason for these differences may be due to individual patient responses to the different training modalities. PURPOSE: To compare changes in physical function and HRQL in a group of COPD patients completing both an endurance and a strength training program. METHODS: Eleven mildly diseased patients completed a three month endurance training program and, approximately 5 years later, completed a three month strength training program...

The number of pharmacological treatments available for COPD has increased markedly in the last years, mostly corresponding to new agents, combinations and devices within know pharmacological classes. Hierarchizing these options is not straightforward since expected effects are limited by the intrinsically fixed character of the underlying lung damage. In addition, all options have not been directly compared face-to-face. Therefore, guidelines derive from some level of subjective interpretation of the available evidence...

In this review, we focused on original manuscripts published in the 2017 that provided additional information on the clinical and therapeutic features of the chronic obstructive pulmonary disease (COPD). We have chosen eight of these studies, collected in four topics concerning the pharmacological treatment (tiotropium) of mild-moderate patients, the pharmacological (fluticasone furoate/vilanterol/umeclidinium) and non-pharmacological treatment (non-invasive mechanical ventilation) of severe patients, the etiology of acute exacerbation of COPD involving seasonal airway pathogens and the role of eosinophils with particular interest to the monoclonal antibody directed against interleukin-5 (mepolizumab)...

Blood eosinophil count may be a useful biomarker for predicting response to inhaled corticosteroids and exacerbation risk in chronic obstructive pulmonary disease (COPD) patients. The optimal cut point for categorizing blood eosinophil counts in these contexts remains unclear. We aimed to determine the distribution of blood eosinophil count in COPD patients and matched non-COPD controls, and to describe demographic and clinical characteristics at different cut points. We identified COPD patients within the UK Clinical Practice Research Database aged ≥40 years with a FEV1 /FVC <0...

Chronic obstructive pulmonary disease is progressive and in its advanced stage is associated with major disability. Previous studies suggest that patients with this disease receive little palliative care, even in very advanced stages. Given this, our objectives were to describe the clinical practice of Spanish pulmonologists in the care of patients with end-stage chronic obstructive pulmonary disease, to identify potential barriers to implementing palliative care in these patients and to correlate these responses with doctor's years of experience...

Magnetotherapy (MT) is a therapeutic treatment based on the use of magnetic fields (MF) that can have an anti-inflammatory and analgesic effect. MT represents a possible treatment or an ancillary therapeutic intervention for a wide range of diseases and it is often used in the field of physiotherapeutic practices. A crucial point in the treatment of chronic obstructive pulmonary disease (COPD) patients, to counteract muscular depletion and respiratory symptoms, is represented by physiotherapy. Nevertheless, the knowledge about the application of MF as a therapeutic option in COPD patients is very limited...

The study of airway diseases continues to present several challenges for modern medicine. The different disease presentations with variables and overlapping features may result in a real challenge for the clinician. In this context, the concept of precision medicine has started to emerge in order to give answers to some of these challenges from a diagnostic and therapeutic point of view. The main reasons to target for precision medicine in chronic obstructive pulmonary disease (COPD) include that there is variability in the clinical presentation, there is no correlation between the different clinical variables at the patient level, there are a number of relevant clinical variables associated with outcomes, we do have specific therapies for specific patient types, and that there is variability in the clinical response to different therapies...

Chronic obstructive pulmonary disease (COPD) is a complex disorder that primarily affects the lungs and is characterized not only by local pulmonary, but also by systemic inflammation which promotes the development of extrapulmonary and cardiovascular co-morbidities. Angiotensin converting enzyme (ACE) inhibitors and ARBs (angiotensin receptor blockers) are widely used drugs in the treatment of cardiovascular diseases, with growing evidence suggesting potential benefits in COPD patients. The purpose of this review is to describe the correlation of renin-angiotensin system (RAS) with COPD pathophysiology and to present the latest data regarding the potential role of RAS blockers in COPD...

Time to exercise limitation (Tlim) in response to constant work rate (CWR) is sensitive to interventions in chronic obstructive pulmonary disease (COPD). This is particularly true when the pre-intervention test lasts between 3 and 8 min (Tlim3'-8' ). There is, however, no simple method to select a work rate which is consistently associated with Tlim3'-8' across the spectrum of COPD severity. We assessed 59 GOLD stages II-IV patients who initially cycled to Tlim at 75% peak. In case of short (<3 min, low-endurance) or long (>8 min, high-endurance) tests, patients exercised after 60 min at 50% or 90%, respectively (CWR50%⇐75%⇒90% )...

This study aimed to increase our understanding of processes that underlie the effect of care pathway implementation on reduced 30-day readmission rate. Adherence to evidence-based recommendations, teamwork and burnout have previously been identified as potential mechanisms in this association. We conducted a secondary data analysis of 257 patients admitted with chronic obstructive pulmonary disease exacerbation and 284 team members caring for these patients in 19 Belgian, Italian and Portuguese hospitals. Clinical measures included 30-day readmission and adherence to a specific set of five care activities...

Clinical trials of pharmacotherapy in chronic obstructive pulmonary disease (COPD) often include older persons with moderate-to-severe airflow-obstruction, as defined by the Global Initiative for chronic Obstructive Lung Disease (GOLD). In this context, spirometric airflow-obstruction establishes COPD. Because GOLD misidentifies COPD and its severity in older persons, we set out to apply more age-appropriate spirometric criteria from the Global Lung function Initiative (GLI) in a prior clinical trial of COPD pharmacotherapy, specifically the Towards a Revolution in COPD Health (TORCH) trial - N = 6,112, mean age 65 years...

The study objective was to determine a cut-off point for the Glittre activities of daily living (ADL)test (TGlittre) to discriminate patients with normal and abnormal functional capacity. Fifty-nine patients with moderate to very severe COPD (45 males; 65 ± 8.84 years; BMI: 26 ± 4.78 kg/m2 ; FEV1 : 35.3 ± 13.4% pred) were evaluated for spirometry, TGlittre, 6-minute walk test (6 MWT), physical ADL, modified Medical Research Council scale (mMRC), BODE index, Saint George's Respiratory Questionnaire (SGRQ), and COPD Assessment Test (CAT)...

A1AT deficiency- a genetically inherited autosomal codominant disease with more than 120 identified alleles- was first identified by Laurell and Eriksson in 1963. The most common hereditary disorder in adults, A1AT causes an increased risk of developing pulmonary emphysema and liver disease. In A1AT patients, lung disease generally presents at a younger age than "usual" chronic obstructive pulmonary disease (COPD) and it may be misdiagnosed as asthma. Because A1AT deficiency patients can show the same clinical features as non-deficient COPD (including increased evidence of bronchiectasis, frequent exacerbations, impaired health status and a degree of reversibility of airflow obstruction), the World Health Organization recommend to test every patient with a diagnosis of COPD or adult-onset asthma for A1AT deficiency...
