Helium-3-MRT der Lungenventilation: Erste klinische Anwendungen

1997

PURPOSE: of the study is the visualisation of normal pulmonary ventilation in healthy volunteers and the evaluation of abnormalities in patients with different lung diseases using 3He magnetic resonance imaging (3He-MRI). MATERIAL AND METHODS: Hyperpolarized 3He gas (V = 300 ml, p = 3 x 10(5) Pa, polarised to 35-45% by optical pumping, provided in special glass cells) was inhaled by eight healthy volunteers and ten patients with different lung diseases. A 3D FLASH sequence (TR = 11.8 ms; TE = 5 ms; matrix 144 x 256, FOV 350 mm, section thickness 7-10 mm, coronal orientation) was performed in a single breath-hold (22-42 s). Clinical and radiological examinations were available for correlatio…

Non-neuronal cholinergic system contributes to corticosteroid resistance in chronic obstructive pulmonary disease patients

2016

Background: Inhaled corticosteroid (ICS) with long-acting beta-2 agonists is a well-documented combination therapy for chronic obstructive pulmonary disease (COPD) based on its additive anti-inflammatory properties. By contrast, the recommendation of ICS in combination with long-acting muscarinic antagonist (LAMA) is not evidence-based. In this study, neutrophils obtained from COPD patients were used to compare the anti-inflammatory effects of aclidinium bromide (a long-acting muscarinic antagonist) with corticosteroids and their potential additive effect. Methods: Human sputum and blood neutrophils were isolated from healthy individuals ( n = 37), patients with stable COPD ( n = 52) and th…

Effects of different physical therapy programs on perceived health status in acute exacerbation of chronic obstructive pulmonary disease patients: a …

2017

To evaluate the repercussion of different physical therapy interventions on the perceived health status of chronic obstructive pulmonary disease (COPD) patients during acute exacerbation.Randomized controlled trial. Patients were assigned to: control group (standard medical treatment), controlled breathing + range of motion exercises group or Resistance exercises group. Perceived health status was assessed at baseline and discharge using the EuroQol-5D (EQ-5D) questionnaire. Clinical profile of patients was evaluated at baseline for descriptive purposes.Ninety patients were randomized into the groups. Perceived health status improved significantly in all groups. Significant differences were…

Aging and disability affect misdiagnosis of COPD in elderly asthmatics: the SARA study

2003

STUDY OBJECTIVES: This study investigated to what extent a diagnosis of COPD is erroneously made or the disease remains unrecognized in elderly asthmatic patients, and identified factors leading to misdiagnosis and underdiagnosis of asthma in such patients. DESIGN: A multicenter study involving 24 Italian pulmonary or geriatric institutions. PATIENTS: One hundred twenty-eight asthmatic patients (98 women, 76.6%) aged 73 +/- 6.4 years (mean +/- SD) were selected from the cohort of the Salute Respiratoria nell'Anziano (respiratory health in the elderly) study. METHODS: All patients underwent a clinical evaluation that included clinical history and spirometry with a bronchodilator test. A diag…

From Global Initiative for Chronic Obstructive Lung Disease (GOLD) Guidelines to Current Clinical Practice

2006

Background: The Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines have been promulgated to improve the management of chronic obstructive pulmonary disorder (COPD). Objective: To evaluate the extent to which the current therapeutic approach to COPD conforms to GOLD guidelines. Methods: This was a multicentre observational study of elderly COPD patients enrolled for acute care in general medicine or geriatric wards in tertiary hospitals in Italy in April 2002. Our series consisted of 471 patients >64 years of age consecutively admitted for acute exacerbations of COPD to wards participating in the study. Data describing drugs used prior to exacerbation and prescribed at …

C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) as inflammation markers in elderly patients with stable chronic obstructive pulmona…

2010

Erythrocyte sedimentation rate (ESR) might represent a less expensive alternative to C-reactive protein (CRP) as a marker of systemic inflammation in stable chronic obstructive pulmonary disease (COPD). We tried to verify this hypothesis in 223 consecutive outpatients aged 65 years or more with stable COPD enrolled in a multicenter observational study. Patients were grouped according to normal/increased ESR/CRP values and groups were compared with regard to clinical and laboratory characteristics. Correlations between CRP, ESR and selected variables of interest were assessed by Spearman's ζ-test and multivariate linear regression analysis. CRP was weakly and inversely correlated with the fo…

The mini nutritional assessment is associated with the perception of dyspnoea in older subjects with advanced COPD

The Gene-Environment Interactions in Respiratory Diseases (GEIRD) Project.

2009

The role of genetic and environmental factors, as well as their interaction, in the natural history of asthma, allergic rhinitis and chronic obstructive pulmonary disease (COPD) is largely unknown. This is mainly due to the lack of large-scale analytical epidemiological/genetic studies aimed at investigating these 3 respiratory conditions simultaneously. The GEIRD project is a collaborative initiative designed to collect information on biomarkers of inflammation and oxidative stress, individual and ecological exposures, diet, early-life factors, smoking habits, genetic traits and medication use in large and accurately defined series of asthma, allergic rhinitis and COPD phenotypes. It is a …

Riociguat versus sildenafil on hypoxic pulmonary vasoconstriction and ventilation/perfusion matching

2017

Introduction Current treatment with vasodilators for pulmonary hypertension associated with respiratory diseases is limited by their inhibitory effect on hypoxic pulmonary vasoconstriction (HPV) and uncoupling effects on ventilation-perfusion (V'/Q'). Hypoxia is also a well-known modulator of the nitric oxide (NO) pathway, and may therefore differentially affect the responses to phosphodiesterase 5 (PDE5) inhibitors and soluble guanylyl cyclase (sGC) stimulators. So far, the effects of the sGC stimulator riociguat on HPV have been poorly characterized. Materials and methods Contraction was recorded in pulmonary arteries (PA) in a wire myograph. Anesthetized rats were catheterized to record …
