Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

Intensive Care Unit (ICU) admission for acute exacerbation of chronic obstructive lung disease (COLD) is a major cause of morbidity and mortality in such patients. Although bacterial of mortality in such patients. Although bacterial and or viral infections are considered as the major precipitating factor, the antibiotic strategy in this setting is unclear. The absence of overt infection remains controversial, and has not been adequately studied in patients admitted to the ICU. To assess the benefit ( or lack thereof ) of routine early systemic antibiotic therapy in patients with COLD admitted to the ICU. The primary objective of the essay is to evaluate the effectiveness of the precocious antibiotic therapy on the length of the respiratory symptoms with the admitted patients in polyvalent medical intensive care of chronic obstructive lung disease ( COLD )

The objective of this study is to determine if tiotropium (Spiriva, Bromuro de Tiotropio) 18 mcg once daily by oral inhalation compared to placebo increases the magnitude of daily physical activity observed in COPD patients, measured using an accelerometer.

This study evaluates the effect of two medicines on COPD (Chronic Obstructive Pulmonary Disease) exacerbations. This study will last up to 56 weeks, and subjects will visit the clinic 10 times. Subjects will be given breathing tests and will record their breathing symptoms daily on diary cards. All study related medicines and medical examinations will be provided at no cost. The two drugs used in this study have been approved by the FDA for use in patients with COPD.

The investigators' aim is to study the effect of cycling off criteria during pressure support ventilation in COPD patients at two levels of PEEP and PSV.

The primary objective of this study is to demonstrate the superiority of tiotropium compared to placebo in the treatment of patients with COPD and a concomitant diagnosis of asthma

The objective of this trial is to compare the total and regional deposition of aerosol in the lungs and oropharynx of patients with COPD at 3 different inspiratory flow rates following inhalation of Berodual delivered via the Respimat inhaler and Berodual? delivered via an HFA-metered dose inhaler.

The investigator wish therefore to continue these studies on theophylline principally by conducting a small clinical pilot study on 20-30 COPD patients in a randomised, double-blind, placebo-controlled, parallel-group study.

To assess the effect of up to 4 years treatment with budesonide on progression of emphysema in patients with Chronic Obstructive Lung Disease.

The primary objective of this study is to estimate the comparative bronchodilator effect size and variability for tiotropium (Spiriva, 18 µg q.d.) with the free combination of salmeterol (Serevent, 50 µg b.i.d.) and fluticasone (Flixotide, 250 µg b.i.d.) in COPD patients. International COPD guidelines preserve milder stages of the disease (GOLD stage I and IIa) to bronchodilators and recommend the addition of inhaled corticosteroids only in those patients who have a documented spirometric response to inhaled corticosteroids and in patients with a post-bronchodilator FEV1 of less than 50% predicted, who suffer from frequent exacerbations requiring oral courses of corticosteroids. Recently published reports indicate that additional bronchodilator efficacy may be achieved when a long-acting beta agonist is combined with an inhaled corticosteroid. Steady state bronchodilation was achieved within one week with the drug combination. However, results of these studies are not consistent, and since the inclusion criteria employed were different from those utilised in the previously conducted tiotropium studies, it is difficult to generalise the observed effects to the general COPD population. In addition, no comparative data is available on the average response over the 12 daytime hours when COPD patients are active and in most need of bronchodilation. 12 hours corresponds to the dosing intervals for both salmeterol and fluticasone.

This randomized, double-blind, placebo-controlled trial assessed the efficacy of montelukast in the treatment of adults ≥50 years of age with persistent asthma and/or COPD. Primary outcomes included forced expiratory volume in one-second (FEV1) and daytime asthma symptoms scores. Nocturnal symptoms, asthma control, health-related quality of life, peak flow measurements, and health care utilization were also assessed as secondary outcomes. Participants were recruited from the Kaiser Permanente Northwest member population. One hundred forty-nine subjects were randomized to treatment with montelukast (10 mg per day) or placebo, and were followed for a six-week period. No differences in lung function measures, health-related quality of life, health care utilization, and asthma symptom scores were observed; however, the montelukast group had slightly improved asthma control scores compared to the placebo group.
