Active clinical trials for "Lung Diseases, Obstructive"

There are few studies about immunological explorations in COPD. Because of the complications of lung biopsies, analyses are generally made on blood samples instead of lung tissue. No study tried to classify COPD vs Asthma vs ACOS. The investigators wondered if there were differences in biomarkers between these groups. The investigators decided to open a pilot-study among COPD patients followed in Amiens-University Hospital. Each patient will be examined and a blood-test will be performed.

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.

This Pilot study evaluates the use of a new device called Inflammacheck and whether it can consistently measure hydrogen peroxide levels in exhaled breath condensate. It will also assess whether exhaled breath condensate hydrogen peroxide levels as measured by Inflammacheck can differentiate people with asthma and COPD from healthy individuals.

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.

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

In a randomized, sham-controlled trial the investigators will test whether supplemental oxygen given during cardiopulmonary exercise testing will improve exercise performance and physiological parameters in patients with chronic obstructive pulmonary disease.

This is an exploratory study to further develop an imaging platform for the assessment of whole lung neutrophil retention. The primary objective of the study is to quantify and compare neutrophil retention in the lungs of lipopolysaccharide-challenged healthy subjects, saline-challenged healthy subjects and subjects with stable COPD. There will be two treatment groups, one with healthy subjects and the other with subjects with stable COPD. The total duration of this study for healthy subjects will be approximately 1 week, in addition to the screening window of 28 days. The total duration of this study for subjects with COPD will be approximately 1 week for those that complete Visit 1 only, and approximately 2 weeks for those subjects with COPD that return to the unit for Visit 2 7-10 days later, in addition to the screening window of 28 days.

This study evaluates if motivational interviewing sessions aiming to motivate recently discharged patients with either chronic obstructive pulmonary disease or congestive heart failure to be active in post-discharge self-management can reduce re-hospitalization rates.
