The ‘real-life’ COPD patient in Germany: The DACCORD study
2016
Abstract Introduction DACCORD is an ongoing, longitudinal, non-interventional study within the German COPD National Prospective Registry. This manuscript describes the baseline characteristics of the first 5924 participants, recruited between November 2012 and November 2013. Methods The main inclusion criteria are a physician diagnosis of COPD, age ≥40 years, and initiating or changing COPD maintenance medication. Data collected included: Demographic and disease characteristics; prescribed medication; symptoms; COPD Assessment Test (CAT); modified Medical Research Council dyspnoea score (mMRC); exacerbations; comorbidities; and forced expiratory volume in 1 s (FEV 1 ). Results Approximately…
Association between urticaria and virus infections: A systematic review
2016
Background The association between urticaria and virus infections has rarely been reported in the literature. The lack of reported cases is probably due to the difficulty in establishing a cause-and-effect relationship. It is not possible to challenge the patient with an etiologic agent. Objective The purpose of this work was to perform a systematic review on the association between urticaria and virus infections. Methods This systematic review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched for articles from January 1, 2008, through May 2015, by using two key terms related to urticaria and virus diseases, "urticaria" and…
A two-year evaluation of the ‘real life’ impact of COPD on patients in Germany: The DACCORD observational study
2017
Abstract Introduction DACCORD is an observational, non-interventional study being conducted in German primary and secondary care centres. The study aims to describe the impact of disease (including exacerbations) and treatments over 2 years on ‘real-life' patients with chronic obstructive pulmonary disease (COPD). Materials and methods Patients had a clinical and spirometry diagnosis of COPD, were aged ≥40 years and, on recruitment, were initiating or changing COPD maintenance medication. The only exclusion criteria were asthma and randomised clinical trial participation. Exacerbations data were collected every 3 months. COPD medication, COPD Assessment Test (CAT) and forced expiratory volu…
Repeatability of exhaled breath fingerprint collected by a modern sampling system in asthmatic and healthy children
2019
E-noses provide potential non-invasive metabolic biomarkers for diagnosing and monitoring pulmonary diseases. The primary aim of the present study was to assess the within-day and between-day repeatability of a modern breath sampling system (Pneumopipe® plus an array of e-nose sensors) in asthmatic and healthy children. The secondary aim was to compare the repeatability of the breath sampling system, spirometry and exhaled nitric oxide (eNO). Fifteen children (age 6-11 years) with asthma and thirty healthy children matched by age and gender (1:2 allocation) were recruited; of them, three healthy children did not complete the study. All measurements were collected twice during the baseline v…
Comparison of risk assessment strategies for not-high-risk pulmonary embolism
2015
We compared the prognostic performance of the 2014 European Society of Cardiology (ESC) risk stratification algorithm with the previous 2008 ESC algorithm, the Bova score and the modified FAST score (based on a positive heart-type fatty acid-binding protein (H-FABP) test, syncope and tachycardia, modified using high-sensitivity troponin T instead of H-FABP) in 388 normotensive pulmonary embolism patients included in a single-centre cohort study.Overall, 25 patients (6.4%) had an adverse 30-day outcome. Regardless of the score or algorithm used, the rate of an adverse outcome was highest in the intermediate-high-risk classes, while all patients classified as low-risk had a favourable outcome…
Aspiration Risk Factors, Microbiology, and Empiric Antibiotics for Patients Hospitalized With Community-Acquired Pneumonia
2021
Background: Aspiration community-acquired pneumonia (ACAP) and community-acquired pneumonia (CAP) in patients with aspiration risk factors (AspRFs) are infections associated with anaerobes, but limited evidence suggests their pathogenic role. Research Question: What are the aspiration risk factors, microbiology patterns, and empiric anti-anaerobic use in patients hospitalized with CAP? Study Design and Methods: This is a secondary analysis of GLIMP, an international, multicenter, point-prevalence study of adults hospitalized with CAP. Patients were stratified into three groups: (1) ACAP, (2) CAP/AspRF+ (CAP with AspRF), and (3) CAP/AspRF- (CAP without AspRF). Data on demographics, comorbidi…
Oral Sustained-Release Aminophylline and Bronchodilator Response to Inhaled Fenoterol in Patients with Chronic Airflow Obstruction
1985
The bronchodilator response to inhaled fenoterol (400 micrograms) was examined in the morning and in the afternoon before and during oral sustained-release aminophylline treatment in eight patients with chronic reversible airway obstruction. Bronchodilatation was evaluated by measuring serial peak expiratory flow rates (PEFR) for eight hours after inhaled fenoterol and calculating the area under the time-response curves and the percentage increment from the baseline values. The patients showed an enhancement of the bronchodilatation achieved with fenoterol in the morning during aminophylline treatment. In the afternoon, instead, the effect of the fenoterol was not improved by oral aminophyl…
Indacaterol once-daily provides superior efficacy to salmeterol twice-daily in COPD: A 12-week study
2011
SummaryBackgroundIndacaterol is a novel, inhaled once-daily ultra-long-acting β2-agonist for the treatment of COPD.MethodsThis 12-week randomised, parallel-group study compared the efficacy of indacaterol 150 μg once-daily to salmeterol 50 μg twice-daily in patients with moderate-to-severe COPD. Assessments included FEV1 standardised area under curve (AUC) from 5 min to 11 h 45 min at Week 12 (primary endpoint), 24-h trough FEV1 (mean of 23 h 10 min and 23 h 45 min post-dose) at Week 12 (key secondary endpoint), FEV1 and FVC measured over 24-h, transition dyspnoea index (TDI) and rescue medication use.ResultsOf 1123 patients randomised 92.1% completed. Mean ± SD age was 62.8 ± 8.78 years, p…
The MRC dyspnoea scale by telephone interview to monitor health status in elderly COPD patients
2010
SummaryDyspnoea is the most common symptom associated with poor quality of life in patients affected by Chronic Obstructive Pulmonary Disease (COPD). While COPD severity is commonly staged by lung function, the Medical Research Council (MRC) dyspnoea scale has been proposed as a more clinically meaningful method of quantifying disease severity in COPD. We wished to assess whether this scale might also be useful during telephone surveys as a simple surrogate marker of perceived health status in elderly patients with COPD.We conducted a comprehensive health status assessment by telephone survey of 200 elderly patients who had a physician diagnosis of COPD. The telephone survey contained 71 it…
Phosphodiesterase 4 inhibition decreases MUC5AC expression induced by epidermal growth factor in human airway epithelial cells
2005
Background: A common pathological feature of chronic inflammatory airway diseases such as asthma and chronic obstructive pulmonary disease (COPD) is mucus hypersecretion. MUC5AC is the predominant mucin gene expressed in healthy airways and is increased in asthmatic and COPD patients. Recent clinical trials indicate that phosphodiesterase type 4 (PDE4) inhibitors may have therapeutic value for COPD and asthma. However, their direct effects on mucin expression have been scarcely investigated. Methods: MUC5AC mRNA and protein expression were examined in cultured human airway epithelial cells (A549) and in human isolated bronchial tissue stimulated with epidermal growth factor (EGF; 25 ng/ml).…
