NCT01513460
This study will assess the efficacy, tolerability and safety of NVA237 compared to tiotropium when added on to fluticasone/salmeterol in patients with chronic obstructive pulmonary disease.
NCT01125098
Exacerbations of chronic obstructive pulmonary disease (COPD) are the first cause of admission to Pulmonary Department in Italy and worldwide. Guidelines recommend treating most patients hospitalized for exacerbations of COPD with antibiotics, even if the role of bacterial infection is often uncertain and the effect of antibiotics poor. The recommendation to use antibiotics is guided by clinical signs and symptoms that have an insufficient diagnostic accuracy, whereas serum biomarkers as procalcitonin (PRO-CT) may guide the selection of COPD patients who need antibiotic treatment. The main aim of the study is to investigate whether antibiotics can be safely stopped after 3 days or continued for 10 days according to a PRO-CT-guided algorithm in patients hospitalized for exacerbations of COPD for whom guidelines recommend 3-10 days antibiotic treatment based on presence of increased dyspnoea, sputum and purulence. The study is designed to assess the non inferiority of the PRO-CT guided plan as compared to the standard guideline recommended plan. The PRO-CT guided withholding of antibiotics is viewed as an experimental intervention associated with less antibiotic-associated complications, eg antibiotic resistance and drug-related side-effect and lower costs. The proposed study is a prospective, randomised controlled, single-blinded intervention trial comparing the standard with a PRO-CT guided antibiotic treatment plan. Patients will be recruited from the Pulmonary Department of 18 University or City Hospitals in Italy, starting October 2006 and continuing until December 2010. Results expected by end of 2011. The 100 patients randomised to the standard non PRO-CT guided antibiotic treatment plan will continue antibiotics for 10 days, whereas the 100 patients randomised to the PRO-CT guided antibiotic treatment plan will continue for 10 days or stop antibiotics on day 3 depending on PRO-CT levels measured at admission, day 1 and day 2. Serum PRO-CT will be measured in a central laboratory. Patients will be examined at admission, discharge, 10 days, 1, 3 and 6 months. A telephone interview will be obtained at 2, 4 and 5 months. The primary outcome of the study will be the rate of exacerbations. Secondary outcomes will be hospital readmission, admission to ICU, change in FEV1, duration of hospitalization, and death. The sample size was estimated according to the primary outcome of the study.

NCT01437748
* The gold standard measures to evaluate small airways (SAW) "in vivo" is not well understood * Two tests are today used to measure SAW but real results concordance is not clear * These problems have a small evidence * Data about real effect of bronchodilators on SAW (eg Tiotropium and Indacaterol) has never been studied * Only an acute bronchodilators effect, after one hour of drugs inhalation, will be evaluated * The time frame of study evaluations per patient will be of three hours: one hour for basal test; one hour rest after drug administration; one hour for post bronchodilators test * All enrolled subjects will be outpatients and will be evaluated after 24 hours of inhalatory drugs washout
NCT01644162
The aim of this study is to determine whether respiratory disease exacerbations (a sudden worsening of symptoms) can be predicted by variables that are monitored by non-invasive ventilators (small machines that assist breathing) in patients requiring long term home ventilation. The investigators hypothesise that acute exacerbations of patients with respiratory disease and ventilatory failure will be predicted by changes in the respiratory variables monitored and stored by ventilators during chronic home ventilator use.
NCT01020344
A randomised controlled trial will be performed to evaluate the effects of lung volume reduction surgery (LVRS) in patients with COPD on systemic inflammation, oxidative stress, endothelial function, arterial stiffness and blood pressure. We hypothesize that LVRS will lead to a reduction of systemic inflammation, oxidative stress, arterial stiffness and blood pressure and to improved endothelial function. For this purpose 30 patients with severe/very severe COPD (GOLD III-IV) and pulmonary emphysema who are to undergo LVRS will be randomised to one of two groups: group 1 receiving immediate LVRS and group 2 receiving LVRS after a delay of 3 months. Measures of systemic inflammation, oxidative stress, endothelial function, arterial stiffness and blood pressure will be measured at baseline and 3 months after surgery and no surgery, respectively (group 2 receiving surgery only after a delay of 3 months will serve as control group) to investigate the effects of LVRS on the described outcomes.
NCT02235129
To compare the relationship between breath-hold time and the distance in a Six Minute Walking Test in chronic obstructive pulmonary disease population.
NCT02234739
voriconazole is recommended as first-line therapy for invasive pulmonary aspergillosis, however the efficacy and safety of voriconazole for treating invasive pulmonary aspergillosis secondary to COPD is not clear. This study aims to investigate the effectiveness and tolerability of intravenous voriconazole for treatment of invasive pulmonary aspergillosis in Chinese patients with COPD, by monitoring changes in clinical symptoms, eradication of aspergillus, improvement of chest imaging as well as record of possible adverse reactions following 2-week intravenous instillation of voriconazole.
NCT01731015
The goal of this study is to perform a pilot study to evaluate the utilization of oxygen as an inhaled contrast agent to image the airway spaces in normal and diseased human lungs to allow an effect size estimate to power future studies.
NCT02001935
The aim of this study is to determine whether common CYP1A2 and CYP2E1 gene polymorphisms effect metabolism of theophylline in chronic obstructive pulmonary disease patients.
NCT00461162
Chronic obstructive pulmonary disease, including emphysema and chronic bronchitis, is the fourth most common cause of death and the second leading cause of disability in the United States. COPD is estimated to be responsible for more than 13.4 million physician visits and 13% of hospitalizations nationally. These hospitalizations are usually caused by acute exacerbations characterized by an increase in symptoms including dyspnea or shortness of breath (SOB), cough, wheezing, and sputum production. The significant disability for people with COPD is primarily due to the symptom of dyspnea (shortness of breath) that affects an individual's quality of life more than does the physiological impairment. Despite optimal medical and pharmacological therapy, most people with COPD continue to suffer from chronic and progressive dyspnea and other symptoms of cough and fatigue. We have previously shown that an individualized face-to-face dyspnea self-management program was effective in improving dyspnea with activities of daily living (ADL), physical functioning, and self-efficacy for managing dyspnea. Using an experimental longitudinal design, the i-DSMP will be compared to the Face-to-Face Dyspnea Self-Management Program (f-DSMP) and to an Attention Control (AC) intervention
NCT02209974
Chronic obstructive pulmonary disease (COPD) is characterized by pulmonary and systemic inflammation. The effect of inhaled corticosteroids (IC) on inflammation in COPD is controversial.
NCT02203058
Background: Dynamic hyperinflation (DH) is an important factor leading to dyspnea and consequent limitations in functional capacity of chronic obstructive pulmonary disease (COPD) patients. It has not been completely elucidated whether pursed-lips breathing (PLB) is able to minimize DH and its effects on exercise tolerance in these patients. The aim of this study was to evaluate the acute effect of PLB on DH and functional capacity in patients with COPD. Design: Randomized cross-over study. Setting: The study will be conducted in an outpatient pulmonary rehabilitation program in Florianópolis, Brazil. Subjects: Twenty-five patients with COPD (16 men, mean age 64 (7) years, FEV1=41.7 (14.7)% predicted, BMI=27.6 (5.13)kg/m2). Interventions: Patients will randomly perform two six-minute walk tests with and without PLB (6MWTPLB and 6MWTNon-PLB) and two Glittre-ADL tests with and without PLB (TGlittrePLB and TGlittreNon-PLB). Main measures: At baseline and immediately after the tests, the inspiratory capacity (IC) will be assessed by the slow vital capacity (SVC) maneuver.
NCT01032304
The aim of the study is to evaluate the effect of erdosteine, compared to placebo, on exacerbation rate over a 12-month treatment period in patients with moderate-to-severe COPD. Moreover, the effects of erdosteine on pulmonary function parameters, clinical symptoms and quality of life, and the long-term safety of the drug will be assessed.
NCT01750489
The objective of the project is to better understand the causes of exercise limitation, dyspnea and neurohumoral activation in patients with COPD. In particular, the investigators aim to explore the mutual interaction of neurohumoral activation and exercise limitation thereby focussing on differential effects of the peripheral muscle and the diaphragm. Eventually the findings might influence treatment modalities. If sympathetic activation contributes to exercise limitation then drugs influencing the autonomic nervous system would be a reasonable therapeutic concept. If a reduction of sympathetic activity due to an alteration of the ergoreflex can be achieved by non-invasive ventilation this would help to improve dyspnea and exercise capacity.

NCT01090986
Non invasive ventilation (NIV) usually presents air leaks that may determine the result of this treatment. The clinical usefulness of analyzing (and quantifying) these leaks during the adaptation period to NIV has not been evaluated in prospective clinical studies as a predictive data of treatment effectiveness. Our hypothesis is that air leaks are correlated to a successful adaptation to NIV. And air leak magnitude may predict early failures of this treatment. And also, as we do not know if air leaks change during the adaptation period to NIV, we do not know whether early detection of air leaks plays a role in the therapeutic outcome. Our objective is to evaluate the clinical usefulness of quantifying air leaks during the adaptation period to NIV as a predictor of effectiveness of this treatment. We also want to evaluate the correlation between air leaks and clinical-functional patients' profile, and the ventilatory parameters selected and to evaluate air leaks variability during the adaptation period to NIV. Method: We will determine the air leak magnitude in twenty patients during adaptation to NIV. We will use VPAP III ventilators (ResMed, Australia), commercial nasal masks (Mirage o Ultra Mirage) and VPAP III/ResLinkTM (ResMed, North Ryde, Australia), a device that includes a monitoring system coupled with the VPAP III ventilator. This device allows to record air leaks and other ventilation parameters. We will perform four VPAP III/ResLinkTM recordings in each patient (the last night in hospital during the adaptation period, the first night at home, and one and two months later, after the initiation of NIV treatment). We will also perform a complete pulmonary function test, quality-of-life questionnaire (SF36), and a tolerance to NIV questionnaire in all patients at the onset of NIV treatment and two months later. We will evaluate which patients will need to change treatment at the end of the adaptation period to NIV. We also will analyze and compare air leaks magnitude in each of the four recordings stated above.
