Filter by:The purpose of the study is to evaluate the significance of KL-6 as a biomarker in the clinical diagnosis of interstitial lung disease (ILD) by detecting serum KL-6 levels among patients with ILD, and comparing them to the clinical diagnostic criteria and other respiratory diseases. In addition, the study discusses the value of KL-6 levels in terms of ILD treatment effect evaluation through the detection of serum KL-6 levels before treatment and after treatment.
This is a Phase IIb, randomized, double blind, chronic dosing (28 days), four period, five treatment, incomplete block, crossover design in subjects with moderate to severe COPD. The overall objective is to demonstrate that the combination of budesonide (BD; PT008) and formoterol fumarate (FF; PT005) in a metered-dose inhaler (MDI); (BFF MDI; PT009) provides benefit on lung function compared with BD MDI in subjects with moderate to severe COPD.
The purpose of this study is to investigate whether flutiform® is effective and safe in the treatment of chronic obstructive pulmonary disease (COPD).
To compare the long-term (one-year) bronchodilator efficacy and safety of COMBIVENT hydrofluoroalkane (HFA) Inhalation Aerosol to COMBIVENT chlorofluorocarbon (CFC) Inhalation Aerosol and Placebo formulations of each in patients with COPD. In addition, steady state pharmacokinetics over one dosing interval following four weeks of therapy will be characterized.
The stroke volume variation (SVV), measured using the Vigileo-FloTrac system (Edwards Lifescience, Irvine, CA), has been shown to able to predict fluid responsiveness during one-lung ventilation (OLV) in patients undergoing pulmonary lobectomy (sensitivity: 82.4%, specificity: 92.3%).1 Many parameters such as tidal volume (TV),1-2 positive end-expiratory pressure (PEEP),3 respiratory rate (RR), 4 chest and lung compliance,5 heart rate and rhythm, and ventricular function and afterload,6-7 all have been documented to have effects on the SVV. SVV is calculated as the variation of beat-to-beat SV from the mean value during the most recent 20 seconds of data: SVV = (SVmax − SVmin)/SVmean, where SVmax, SVmin, and SVmean are, respectively, the maximum, minimum, and mean SV determined by the system. SVV may not be sufficiently sensitive to predict fluid responsiveness in patients with right ventricular (RV) dysfunction due to concomitant increases in RV afterload, that lead to a decrease in preload variation and subsequent inaccuracy in SVV measurements.8 OLV may increase airway pressure, resulting in increases in the RV afterload, end-diastolic volume, and stroke work index, thus impeding RV function.9-11The increases in the right ventricular afterload may exaggerate the cyclic variation in stroke volume.12 In the authors' previous study,9 they found that the high-frequency positive-pressure ventilation (HFPPV) was superior to continuous positive-airway pressure (CPAP) for OLV, resulting in significantly higher RV ejection fraction, lower RV afterload and higher arterial oxygenation, whereas the former limiting the adequate operative field visualization during video-assisted thoracoscopic surgery (VATS).13 The effects of the nondependent lung ventilation with HFPPV and CPAP on the SVV and fluid responsiveness during OLV has not yet been studied.
Open clinical trial with 1 year follow up comparing the impact of an Early Respiratory Rehabilitation program with the conventional Respiratory Rehabilitation in COPD re-admitted patients. Outcomes will be exacerbations, symptoms, functional capacity and quality of life related to health (HRQOL).
The purpose of this study is to evaluate the efficacy and safety of CHF 5259 (glycopyrrolate bromide) for the treatment of COPD patients.
E-cigarettes are an increasingly popular alternate nicotine delivery system, but nothing is known about the effects of electronic cigarettes on the lungs. We hypothesize that e-cigarettes disorder airway epithelial and alveolar macrophages biology. Our goal is not to carry out a large epidemiologic study of electronic cigarette users to study lung function and other possible abnormal clinical phenotypes, but rather to focus on whether electronic cigarette smoke disorders the biology of the lung cells first exposed to the electronic cigarette smoke, a parameter that is the precursor of abnormalities in lung function and which is far more sensitive than lung function.
The purpose of this study was to examine the characteristics of patients selected for treatment with roflumilast and the effectiveness and safety of roflumilast in patients with severe or very severe COPD treated in Hospital and outpatient specialist ward settings in Greece.
The improvement in inspiratory muscle function might result in beneficial changes in breathing pattern during whole body exercise. The hypothesis is the effect of inspiratory muscle training as an adjunct to a pulmonary rehabilitation program improves the breathing pattern during an incremental cycle exercise.
