Different Patterns of Lung Sirtuin Expression in Smokers With and Without Chronic Obstructive Pulmonary Disease

2012

Background and Objective. Chronic obstructive pulmonary disease is characterized by persistent and modified inflammatory responses in lung. Human sirtuin, an antiaging and antiinflammatory protein, is a metabolic NAD(+)-dependent protein/histone deacetylase that regulates proinflammatory mediators by deacetylating histone and nonhistone proteins. The aim of our study was to compare the expression of sirtuin in large and small airways in nonsmokers, asymptomatic smokers, and smokers with chronic obstructive pulmonary disease. Material and Methods. A total of 12 nonsmokers, 14 asymptomatic smokers, and 12 smokers with moderate chronic obstructive pulmonary disease were enrolled into the study…

Abnormal thyroid hormones and non-thyroidal illness syndrome in obstructive sleep apnea, and effects of CPAP treatment

2016

Objective In obstructive sleep apnea (OSA), while both hypothyroidism and hyperthyroidism have been studied, the occurrence of non-thyroidal illness syndrome (NTIS) (normal thyroid stimulating hormone [TSH] with low triiodotironine) has not been investigated. We explored the occurrence of NTIS in patients with moderate to severe OSA and its relationship to the severity of nocturnal respiratory disorders. We also studied the occurrence of subclinical hypothyroidism (SH, ie, high TSH with normal thyroxine) in OSA and changes in circulating TSH, free triiodotironine (fT3) and free thyroxine (fT4) after CPAP treatment. Methods After a nocturnal respiratory polysomnography, 125 consecutive patie…

Acetylcholine leads to signal transducer and activator of transcription 1 (STAT-1) mediated oxidative/nitrosative stress in human bronchial epithelia…

2013

AbstractThe induction of nitric oxide synthase (iNOS) expression via the signal transducer and activator of transcription 1 (STAT-1) is involved in the mechanism of oxidative/nitrosative stress. We investigated whether acetylcholine (ACh) generates oxidative/nitrosative stress in bronchial epithelial cells during airway inflammation of COPD and evaluated the effects of Tiotropium, a once-daily antimuscarinic drug, and Olodaterol, a long-acting β2-agonist on these mechanisms. Human bronchial epithelial cells (16-HBE) were stimulated (4h, 37°C) with induced sputum supernatants (ISSs) from healthy controls (HC) (n=10), healthy smokers (HS) (n=10) or COPD patients (n=10), as well as with ACh (f…

Pattern of comorbidities and 1-year mortality in elderly patients with COPD hospitalized in internal medicine wards: data from the RePoSI Registry

2020

Currently, chronic obstructive pulmonary disease (COPD) represents the fourth cause of death worldwide with significant economic burden. Comorbidities increase in number and severity with age and are identified as important determinants that influence the prognosis. In this observational study, we retrospectively analyzed data collected from the RePoSI register. We aimed to investigate comorbidities and outcomes in a cohort of hospitalized elderly patients with the clinical diagnosis of COPD. Socio-demographic, clinical characteristics and laboratory findings were considered. The association between variables and in-hospital, 3-month and 1-year follow-up were analyzed. Among 4696 in-patient…

[Risk factors of readmission in acute exacerbation of moderate-to-severe chronic obstructive pulmonary disease].

2004

More effective management of chronic obstructive pulmonary disease (COPD) and improved survival of COPD patients requires a better understanding of the risk factors for exacerbation. The aim of this study was to identify factors related to readmission in patients with moderate-to-severe COPD.Ninety patients with moderate-to-severe COPD hospitalized consecutively for acute exacerbation were studied prospectively. At discharge, the following potential predictors were assessed: clinical and spirometric variables, arterial blood gases, and respiratory muscle strength determined noninvasively. The patients were followed for a period of 3 months. Readmission for exacerbation and time intervals fr…

Gelatinases and their tissue inhibitors in a group of subjects with obstructive sleep apnea syndrome.

2016

Obstructive sleep apnea syndrome (OSAS) is associated with an elevated risk of cardiovascular events and stroke. Matrix metalloproteinases (MMPs) are endopeptidases involved in extracellular matrix degradation and then in the development and progression of cardiovascular diseases. Our aim was to evaluate plasma levels of gelatinases (MMP-2 and MMP-9) and their tissue inhibitors (TIMP-1 and TIMP-2) in a group of subjects with OSAS. We enrolled 48 subjects (36 men and 12 women; mean age 49.7 ± 14.68 yrs) with OSAS diagnosed with a 1-night cardiorespiratory study and then we subdivided these subjects into two subgroups according to the apnea/hypopnea index (AHI): Low (L = 21 subjects with AHI …

Muscarinic receptors, leukotriene B4 production and neutrophilic inflammation in COPD patients.

2005

Background:  Acetylcholine (ACh) plays an important role in smooth muscle contraction and in the development of airway narrowing; preliminary evidences led us to hypothesize that ACh might also play a role in the development of airways inflammation in chronic obstructive pulmonary disease (COPD). Methods:  We evaluated the concentrations of leukotriene B4 (LTB4) in induced sputum, and the expression of Ach M1, M2, and M3 receptors in sputum cells (SC) obtained from 16 patients with COPD, 11 smokers, and 14 control subjects. The SC were also treated with ACh and the production of LTB4 assessed in the presence or absence of a muscarinic antagonist (oxitropium). In blood monocytes, we evaluate…
