Innate immunity but not NLRP3 inflammasome activation correlates with severity of stable COPD.

2014

Background In models of COPD, environmental stressors induce innate immune responses, inflammasome activation and inflammation. However, the interaction between these responses and their role in driving pulmonary inflammation in stable COPD is unknown. Objectives To investigate the activation of innate immunity and inflammasome pathways in the bronchial mucosa and bronchoalveolar lavage (BAL) of patients with stable COPD of different severity and control healthy smokers and non-smokers. Methods Innate immune mediators (interleukin (IL)-6, IL-7, IL-10, IL-27, IL-37, thymic stromal lymphopoietin (TSLP), interferon γ and their receptors, STAT1 and pSTAT1) and inflammasome components (NLRP3, NA…

High resolution computed tomography quantitation of emphysema is correlated with selected lung function values in stable COPD.

2011

BACKGROUND: The literature shows conflicting results when high-resolution computed tomography (HRCT) scores of emphysema were correlated with different indices of airflow obstruction. OBJECTIVES: We correlated HRCT scores of emphysema with different indices of airflow obstruction. METHODS: We performed HRCT of the chest in 59 patients, all smokers or ex-smokers, with stable chronic obstructive pulmonary disease of different severity [GOLD stages I-IV; mean age ± SD 67.8 ± 7.3 years; pack/years 51.0 ± 34.6; percent predicted forced expiratory volume in 1 s (FEV(1)% predicted) 52.3 ± 17.6; post-bronchodilator FEV(1)% predicted 56.5 ± 19.1; FEV(1)/forced vital capacity (FVC) ratio 50.8 ± 10.2;…

Pulmonary hypertension in COPD and lung transplantation: Timing and procedures

2014

The prevalence of pulmonary hypertension (PH) in the general chronic obstructive pulmonary disease (COPD) population is undefined because stable COPD patients do not routinely undergo screening echocardiogram and right heart catheterization. Most studies published on this topic are focused on a highly selected group of patients with moderate to severe disease awaiting lung transplantation, since hemodynamic data from cardiac catheterization are part of the standard transplant evaluation. In a very recent article, Hurdman et al. studied the characteristics and outcomes, with a particular focus on mortality, of extensively phenotyped, consecutive patients with PH-COPD over a 9-year period. Th…

COPD classification methods and informativeness on mortality: Contrasting evidences

2013

Understanding whether the ABCD GOLD classification method is informative with respect to the spirometric classification of severity in predicting mortality of patients with chronic obstructive pulmonary disease (COPD) is subject of debate. The results of a study performed on a sample of the Norwegian population (HUNT2) were recently published. Such data showed the inferiority of ABCD classification in predicting mortality compared to the spirometric classification, which was considered the gold standard up to the 2011 version of GOLD guidelines. This result is not in line with the results of other studies that have shown the equivalence of the two classifications. The new GOLD classificatio…

Extracorporeal Shock Waves Increase Markers of Cellular Proliferation in Bronchial Epithelium and in Primary Bronchial Fibroblasts of COPD Patients

2020

Chronic obstructive pulmonary disease (COPD) is due to structural changes and narrowing of small airways and parenchymal destruction (loss of the alveolar attachment as a result of pulmonary emphysema), which all lead to airflow limitation. Extracorporeal shock waves (ESW) increase cell proliferation and differentiation of connective tissue fibroblasts. To date no studies are available on ESW treatment of human bronchial fibroblasts and epithelial cells from COPD and control subjects. We obtained primary bronchial fibroblasts from bronchial biopsies of 3 patients with mild/moderate COPD and 3 control smokers with normal lung function. 16HBE cells were also studied. Cells were treated with a…

Redox regulation of genome stability by effects on gene expression, epigenetic pathways and DNA damage/repair

2015

Reactive oxygen and nitrogen species (e.g. H2O2, nitric oxide) confer redox regulation of essential cellular signaling pathways such as cell differentiation, proliferation, migration and apoptosis. In addition, classical regulation of gene expression or activity, including gene transcription to RNA followed by translation to the protein level, by transcription factors (e.g. NF-κB, HIF-1α) and mRNA binding proteins (e.g. GAPDH, HuR) is subject to redox regulation. This review will give an update of recent discoveries in this field, and specifically highlight the impact of reactive oxygen and nitrogen species on DNA repair systems that contribute to genomic stability. Emphasis will be placed …

The Determinants of Living with Long-Term Conditions: An International Cross-Sectional Study

2021

It is essential that healthcare and social professionals understand the daily lives of people with chronic diseases, and the variables that influence them. The aim of this study was to identify the determinants influencing the process of living with long-term conditions. To investigate this, an observational, international, cross-sectional study was carried out. A consecutive sample of 1788 Spanish-speaking population living with chronic obstructive pulmonary disease, chronic heart failure and type 2 diabetes mellitus were included. Descriptive statistics and multiple linear regression models were performed. The linear regression models identified that social support (β = 0.39, p &lt

IκB kinase-driven nuclear factor-κB activation in patients with asthma and chronic obstructive pulmonary disease.

2011

Background Nuclear factor-κB (NF-κB) is a transcriptional factor of different inflammatory patterns involved in asthma and chronic obstructive pulmonary disease (COPD) that is tightly controlled by IκB kinase (IKK) complex. Objective We investigated the dysregulation of IKK-driven NF-κB activation in patients with asthma and COPD. Methods We assessed IKKα and IKKβ expression and activation, their regulation by glucocorticosteroids, and their involvement in IL-8 synthesis in PBMCs isolated from asthmatic patients, healthy smokers (HSs), patients with COPD, and control subjects. PBMCs from control subjects were stimulated with TNF-α and cigarette smoke extract in the presence or absence of fl…
