P120 Real life distribution of COPD severity in the German DACCORD registry: Lung function is the main driver of classification in GOLD group C and D

2015

Introduction Currently there is limited real-life data available regarding the distribution of COPD patients using the GOLD 2011 criteria. The German DACCORD registry that collects data from a large ‘real life’ population sample was used to categorise COPD patients according to GOLD 2011. Methods To be eligible for entry into DACCORD, all patients had to have a diagnosis of COPD (consistent with the German Disease Management Programme definition), and, prior to entry, had to have either newly initiated bronchodilator maintenance medication, or to have a bronchodilator added to their maintenance regimen. No other inclusion criteria were applied, and the only exclusion criterion was a diagnos…

Tiotropium and olodaterol fixed-dose combination versus mono-components in COPD (GOLD 2-4).

2015

Efficacy and safety of tiotropium+olodaterol fixed-dose combination (FDC) compared with the mono-components was evaluated in patients with moderate to very severe chronic obstructive pulmonary disease (COPD) in two replicate, randomised, double-blind, parallel-group, multicentre, phase III trials. Patients received tiotropium+olodaterol FDC 2.5/5 μg or 5/5 μg, tiotropium 2.5 μg or 5 μg, or olodaterol 5 μg delivered once-daily via Respimat inhaler over 52 weeks. Primary end points were forced expiratory volume in 1 s (FEV1) area under the curve from 0 to 3 h (AUC0–3) response, trough FEV1 response and St George's Respiratory Questionnaire (SGRQ) total score at 24 weeks. In total, 5162 patien…

Small airways function and molecular markers in exhaled air in mild asthma.

2005

Background: Several studies suggest that the periphery of the lung is the major site of inflammation in asthma. Fractional exhaled nitric oxide (FeNO) and 8-isoprostane have been proposed as biomarkers of inflammation and oxidative stress. We therefore hypothesised that small airway dysfunction in asthma is of inflammatory origin that can be detected by molecular markers in exhaled air. To test this hypothesis, we examined the relationship of FeNO and 8-isoprostane in exhaled air with small airways function as assessed by the single breath nitrogen test. Methods: Sixteen patients (14 women) with mild atopic asthma (forced expiratory volume in 1 second >80% predicted) of mean (SD) age 23.0 (…

Late consequences of traumatic rupture of the diaphragm.

2013

A 54-year-old man was admitted to our clinic due to elevated γ-glutamyltransferase, without any clinical symptoms. About 25 years ago, he had undergone blunt abdominal and thoracic trauma during an accident. No diagnostic measures or therapy had been performed at that time. Serum bilirubin was normal, but the values for alanine transaminase, aspartate transaminase, and alkaline phosphatase were slightly above the reference range. Sonography of the abdomen revealed dilated intrahepatic bile ducts up to 3 mm in diameter and steatosis of the liver grade I. CT scan and MRI of the thorax and abdomen showed a giant hiatal hernia with transposition of upper abdominal organs into the chest. As the …

Validation of FEV6 in the elderly: correlates of performance and repeatability.

2007

BACKGROUND: Forced expiratory volume in 6 s (FEV6) has been proposed as a more easily measurable parameter than forced vital capacity (FVC) to diagnose airway disease using spirometry. A study was undertaken to estimate FEV6 repeatability, to identify correlates of a good quality FEV6 measurement and of volumetric differences between FEV6 and FVC in elderly patients. METHODS: 1531 subjects aged 65-100 years enrolled in the SA.R.A project (a cross-sectional multicentre non-interventional study) were examined. FEV6 was measured on volume-time curves that achieved satisfactory start-of-test and end-of-test criteria. Correlates of FEV6 achievement were assessed by logistic regression. RESULTS: …

Recurrent respiratory infections caused by a double aortic arch: The diagnostic role of spirometry

2013

AbstractA young woman with a clinical history characterized by recurrent respiratory infections, occurring since early infancy, was referred to our hospital. When the patient was a young girl, she underwent sweat chloride test, serum analysis of immunoglobulins, and evaluation of blood lymphocyte subsets; all these diagnostic tests were normal, as well as chest X ray aside from pneumonia episodes. Skin prick tests were positive for several different allergens, and a diagnosis of allergic rhinitis was made. At the age of 11 years, she started to complain of gastroesophageal reflux disease (GERD) symptoms, and a gastroscopy detected a hiatal hernia with esophagitis. Despite pharmacologic trea…

Exploring the relevance and extent of small airways dysfunction in asthma (ATLANTIS): baseline data from a prospective cohort study

2019

BACKGROUND: Small airways dysfunction (SAD) is well recognised in asthma, yet its role in the severity and control of asthma is unclear. This study aimed to assess which combination of biomarkers, physiological tests, and imaging markers best measure the presence and extent of SAD in patients with asthma.METHODS: In this baseline assessment of a multinational prospective cohort study (the Assessment of Small Airways Involvement in Asthma [ATLANTIS] study), we recruited participants with and without asthma (defined as Global Initiative for Asthma severity stages 1-5) from general practices, the databases of chest physicians, and advertisements at 29 centres across nine countries (Brazil, Chi…

Why chronic obstructive pulmonary disease patients get so short of breath with limited activity

2013

equivalence despite the simplicity of MPT versus CPET as a surrogate to detect DH in COPD patients, by measuring the decrease in inspiratory capacity to reflect the increase in end-expiratory lung volume [3] . Lahaije et al. [2] have investigated whether DH as measured in the laboratory settings (CPET and MPT) reflects DH that is associated with dyspnea-limiting ADL. The authors conclude that both CPET and MPT can serve as a screening tool to identify patients who are susceptible to develop DH during ADL. In practice, MPT is simpler to obtain and is an inexpensive surrogate. However, sensitivity of MPT may not be optimal. When DH does not occur during CPET, it is unlikely to occur during AD…

Age is associated with asthma phenotypes

2017

Background and objective The relationship between age and asthma phenotypes is important as population is ageing, asthma is becoming common in older ages and recently developed treatments for asthma are guided by phenotypes. The aim of this study is to evaluate whether age is associated with specific asthma phenotypes. Methods This is a cross-sectional study. We included subjects with asthma of varied degrees of severity. Subjects underwent spirometry, skin prick test to aeroallergens, answered the Asthma Control Questionnaire and had blood samples collected. We performed binary logistic regression analysis to evaluate whether age is associated with asthma phenotypes. Results We enrolled 86…
