Prevalence of Co-morbidities and severity of COPD
2014
Abstract We aimed at exploring whether the prevalence of co-morbidities of chronic obstructive pulmonary disease (COPD) increases with COPD severity. Analysis of medical records of outpatients with established diagnosis of COPD was retrospectively performed. The lower limit of normality (LLN) for FEV1/FVC was applied to establish the occurrence of airway obstruction in the elderly population. The prevalence of co-morbidities was calculated, and the proportion of patients with each co-morbidity along with GOLD stages was analysed by chi-square for trend. A total of 326 (M/F: 256/70) consecutive outpatients with COPD (stage GOLD I to IV), aging 71.8 ± 9.2 years, were included in the analysis.…
COPD at the end of life: Predictors of the emotional distress of patients and their family caregivers.
2020
BackgroundFew studies have focused on patients' emotional distress with end-stage chronic obstructive pulmonary disease (COPD) and their main family caregivers.MethodsCross-sectional data about emotional, functional, and burden-related variables were collected from 85 patients with end-stage COPD and their 85 respective main family caregivers to determine the variables that could predict their emotional well-being. Descriptive analyses, comparison of means, hierarchical regression models, and comparative quali-quantitative analyses were carried out.ResultsData show that the great majority of patients with COPD spend years with this diagnosis, and have been admitted to the hospital several t…
Risk of Stroke and Post-Stroke Adverse Events in Patients with Exacerbations of Chronic Obstructive Pulmonary Disease
2017
Background The risk and outcomes of stroke in patients with chronic obstructive pulmonary disease exacerbations (COPDe) remain unclear. We examined whether patients with COPDe faced increased risk of stroke or post-stroke outcomes. Methods Using Taiwan’s National Health Insurance Research Database, we identified 1918 adults with COPDe and selected comparison cohorts of 3836 adults with COPD no exacerbations and 7672 adults without COPD who were frequency matched by age and sex in 2000–2008 (Study 1). Stroke event was identified during 2000–2013 follow-up period. Adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of stroke associated with COPDe were calculated. In a nested cohor…
In vitro anti-inflammatory effects of AZD8999, a novel bifunctional muscarinic acetylcholine receptor antagonist /β2-adrenoceptor agonist (MABA) comp…
2019
Recent evidence indicates that AZD8999 (LAS190792), a novel muscarinic acetylcholine receptor antagonist and β2-adrenoceptor agonist (MABA) in development for chronic respiratory diseases, induces potent and sustained relaxant effects in human bronchi by adressing both muscarinic acetylcholine receptors and β2-adrenoceptor. However, the anti-inflammatory effects of the AZD8999 monotherapy or in combination with corticosteroids are unknown. This study investigates the anti-inflammatory effects of AZD8999 in monotherapy and combined with fluticasone propionate in neutrophils from healthy and chronic obstructive pulmonary disease (COPD) patients. Peripheral blood neutrophils from healthy and C…
The COPD multi-dimensional phenotype: A new classification from the STORICO Italian observational study.
2019
BackgroundThis paper is aimed to (i) develop an innovative classification of COPD, multi-dimensional phenotype, based on a multidimensional assessment; (ii) describe the identified multi-dimensional phenotypes.MethodsAn exploratory factor analysis to identify the main classificatory variables and, then, a cluster analysis based on these variables were run to classify the COPD-diagnosed 514 patients enrolled in the STORICO (trial registration number: NCT03105999) study into multi-dimensional phenotypes.ResultsThe circadian rhythm of symptoms and health-related quality of life, but neither comorbidity nor respiratory function, qualified as primary classificatory variables. Five multidimension…

Restrictive pulmonary dysfunction at spirometry and mortality in the elderly
2008
SummaryObjectivesTo evaluate the association between pulmonary restriction and mortality in the elderly, taking into account potential confounders not considered in the past (disability, cognitive dysfunction, diabetes, and visceral obesity).DesignLongitudinal study.SettingCommunity-based.ParticipantsTwelve hundred sixty-five patients (51.9% men) aged 65–97 years old from the Salute Respiratoria nell'Anziano (SaRA) Italian multicentric study.MeasurementsParticipants were divided in 4 groups: normal spirometry (NS): FEV1/FVC≥70%, FVC≥80% of predicted; restrictive ventilatory pattern (RVP): FEV1/FVC≥70%, FVC<80%; obstructive ventilatory pattern (OVP): FEV1/FVC<70%, FVC≥80%, and mixed ventilat…
Convergent sets of data from in vivo and in vitro methods point to an active role of Hsp60 in chronic obstructive pulmonary disease pathogenesis.
2011
BackgroundIt is increasingly clear that some heat shock proteins (Hsps) play a role in inflammation. Here, we report results showing participation of Hsp60 in the pathogenesis of chronic obstructive pulmonary diseases (COPD), as indicated by data from both in vivo and in vitro analyses.Methods and resultsBronchial biopsies from patients with stable COPD, smoker controls with normal lung function, and non-smoker controls were studied. We quantified by immunohistochemistry levels of Hsp10, Hsp27, Hsp40, Hsp60, Hsp70, Hsp90, and HSF-1, along with levels of inflammatory markers. Hsp10, Hsp40, and Hsp60 were increased during progression of disease. We found also a positive correlation between th…
Major adverse cardiovascular events in non-valvular atrial fibrillation with chronic obstructive pulmonary disease: the ARAPACIS study
2018
Chronic obstructive pulmonary disease (COPD) increases the risk of mortality in non-valvular atrial fibrillation (NVAF) patients. Data on the relationship of COPD to major cardiovascular events (MACE) in AF have not been defined. The aim of the study is to assess the predictive value of COPD on incident MACE in NVAF patients over a 3-year follow-up. In the Atrial Fibrillation Registry for Ankle-Brachial Index Prevalence Assessment-Collaborative Italian Study (ARAPACIS) cohort, we evaluate the impact of COPD on the following clinical endpoints: MACE (including vascular death, fatal/non-fatal MI and stroke/TIA), cardiovascular (CV) death and all-cause mortality. Among 2027 NVAF patients, pati…
