Sex-specific differences in chronic thromboembolic pulmonary hypertension. Results from the European CTEPH registry
2019
BACKGROUND: Women are more susceptible than men to several forms of pulmonary hypertension, but have better survival. Sparse data are available on chronic thromboembolic pulmonary hypertension (CTEPH). METHODS: We investigated sex-specific differences in the clinical presentation of CTEPH, performance of pulmonary endarterectomy (PEA), and survival. RESULTS: Women constituted one-half of the study population of the European CTEPH registry (N = 679) and were characterized by a lower prevalence of some cardiovascular risk factors, including prior acute coronary syndrome, smoking habit, and chronic obstructive pulmonary disease, but more prevalent obesity, cancer, and thyroid diseases. The med…
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…
Hospital Care of Older Patients With COPD: Adherence to International Guidelines for Use of Inhaled Bronchodilators and Corticosteroids
2019
Abstract Objectives We aimed to analyze the prevalence and impact of COPD in older patients hospitalized in internal medicine or geriatric wards, and to investigate adherence to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines, associated clinical factors, and outcomes. Design Data were obtained from REgistro POliterapie SIMI (REPOSI), a prospective multicenter observational registry that enrolls inpatients aged ≥65 years. Setting and Participants Older hospitalized patients enrolled from 2008 to 2016 with a diagnosis of COPD. Measures We evaluated adherence to the 2018 GOLD guidelines at admission and discharge, by examining the prescription of inhaled bronchodi…
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…
Metabolic Syndrome in Patients with Coexistent Obstructive Sleep Apnea Syndrome and Chronic Obstructive Pulmonary Disease (Overlap Syndrome).
2020
Background: Evidence suggests that metabolic syndrome (MetS) is highly prevalent in patients with obstructive sleep apnea syndrome (OSAS) and chronic obstructive pulmonary disease (COPD). However, ...
[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…
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…
Patterns and predictors of exhaustion episodes in patients with stable COPD: A longitudinal study.
2017
Background and objective Exhaustion is the perception of low energy. Little is known about how exhaustion persists, remits or reappears over time in patients with chronic obstructive pulmonary disease (COPD) or how to predict these events. We determined the likelihood of transitions between states of exhaustion and no exhaustion among patients with stable COPD followed up for 2 years. We investigated combinations of potential factors for their abilities to predict new-onset exhaustion episodes. Methods We prospectively included 137 patients with stable COPD (mean age, 66.9 years ± 8.3). Exhaustion states were measured at baseline and 1 and 2 years later. Exhaustion was defined as an answer …
Lobar lung resection in elderly patients with non-small cell lung carcinoma: impact of chronic obstructive pulmonary disease on surgical outcome.
2014
AbstractThe aim of this study was to evaluate the impact of chronic obstructive pulmonary disease (COPD) on the perioperative morbidity and mortality after lobar lung resection for non-small cell lung cancer (NSCLC) in patients aged 70 years and older. The medical records of 73 patients ≥70 years who underwent lobar lung resection for NSCLC from 2003 to 2013 at our department were reviewed retrospectively. There were 27 patients with a mean age of 73.6 years and mean predicted forced expiratory volume in 1 s (FEV1) of 69.7% in the COPD group whereas remaining 46 patients (mean age = 75.6 years) in the non-COPD group had a mean predicted FEV1 of 79.1%. There were no significant differences i…
