Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

This research is being done to study mechanisms of progression of COPD and to develop treatments for it. The investigators are doing the present study to identify people age 40 and older with mild to moderate COPD who will qualify for such studies to include in a database. The study will include establishing a screening evaluation or characterization of the following two studies: Emphysema Progression in COPD- Losartan's Effects on Airway Parameters - NA_00009980 Sleep-Related Physiology and Inflammation in Chronic Obstructive Pulmonary Disease - NA_00001771

The correct use of inhalation devices is an inclusion criterion for all studies comparing inhaled treatments. In real life, however, patients may make many errors with their usual inhalation device, which may negate the benefits observed in clinical trials. In real life, many errors seem to be made, but no wide-scale evaluation has been performed. The correct use of inhalation devices is essential to ensure the effectiveness of the treatment. It has been recently demonstrated that inhaler misuse is associated with decreased asthma control in asthmatics treated with an inhaled corticosteroid. The aim of our observational study was to evaluate the inhaler device usage in patients with asthma or chronic obstructive pulmonary disease (COPD).

Weaning of mechanical ventilation (MV) is an essential part in management of patients with Chronic Obstructive Pulmonary Disease (COPD) when critically ill. The best strategy to be used has not been established. Objective: To compare the Spontaneous Breathing Trial (SBT) in Pressure Support Ventilation with SBT through "T" tube in weaning of MV in patients with COPD. Design: Randomized Clinical Trial. Methods: This study will include patients with COPD, admitted to the Intensive Care Unit of Hospital Nossa Senhora da Conceição, undergoing MV for at least 48 hours. When considered by the care team ready for SBT, they will be randomized to one of the following strategies: SBT in Pressure Support or SBT through "T" Tube. The primary endpoint of this study will be the reduction in the days spent on MV. Other outcomes measured will be mortality, extubation and success rate, time to weaning of MV, length of ICU stay and incidence of tracheostomy.

The aim of the study is to develop a new patient-reported outcome (PRO) questionnaire measuring the impact of an acute exacerbation on daily lives of patients with chronic obstructive pulmonary disease (COPD). This questionnaire will aim to detect an acute exacerbation and resolution of exacerbation from the patient's perspective. At a later stage of development, this questionnaire will be able to measure the effect of anti bacterials in the treatment of acute exacerbations of COPD (AECOPD). This study will evaluate the factor structure, validity, reliability, and responsiveness of the GSK questionnaire in subjects who experience acute exacerbations of their COPD.

To prospectively identify factors that influence the rate of decline in pulmonary function and to identify predictors of chronic obstructive lung disease (COLD) and asthma in a population sample of older adults.

Better understanding of the specificities of the vaccine response in patients with COPD

This is a qualitative research exploration engaging clinical staff at all levels from 10 Practice-Based Research Networks (PBRNs) serving US patient populations of differing gender, racial, ethnic, urban/rural and socio-economic blends, in the incorporation of a one-page, five-item questionnaire with selective PEF measurement (CAPTURE).

The rationale for this non-interventional study in confirmed moderate to severe chronic obstructive pulmonary disease patients aged 40 years and above, is to assess real-life effectiveness and safety of Trimbow® in clinical practice, and to bridge the gap with the existing clinical data.

The aim of the study is to determine if increased retrograde shear would further deteriorate the already impaired vascular function in severe COPD patients.

The purpose is to evaluate exercise performance in patients with Chronic Obstructive Pulmonary Disease (COPD) after supplementing with higher doses of dietary NO3-, compared to previous studies, as beetroot juice for seven days. The secondary purpose is to evaluate oxygen consumption of submaximal cycling, amendments in blood pressure, and physical activity level.
