Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Diagnosis / Prognosis - Blood sampling, FeNO, bronchoalveolar lavage, bronchoscopic tissue sampling

Patients with COPD - The following parameters are to be evaluated:

* Blood eosinophils
* FeNO
* Eosinophils in bronchoalveolar lavage
* Tissue eosinophilia (protected specimen brush sampling, endobronchial biopsy)

Patients with asthma - The following parameters are to be evaluated:

* Blood eosinophils
* FeNO
* Eosinophils in bronchoalveolar lavage
* Tissue eosinophilia (protected specimen brush sampling, endobronchial biopsy)


Diagnosis / Prognosis: Blood sampling, FeNO, bronchoalveolar lavage, bronchoscopic tissue sampling
Blood sampling (eosinophil count; eosinophilia is defined as \>300/µl (or \>150/µl during oral glucocorticosteroid treatment); FeNO: Measurement of fractional nitric oxide (NO) concentration in exhaled breath; Bronchoscopy: BAL: total leukocyte counts and leukocyte differential counts including eosinophils, PSB sampling: eosinophil count/100 cells, endobrochial biopsy: tissue eosinophil count/100 cells.

Summary
Brief summary
Scientific research focuses on "eosinophilic inflammation" as it seems to guide the therapeutic regimen in patients with asthma and COPD. The primary objective of this prospective trial is to evaluate which parameter(s) best reflects eosinophilic inflammation by correlating tissue eosinophils (endobronchial biopsy, protected specimen brush sampling) with FeNO, peripheral blood eosinophils, and eosinophils in the bronchoalveolar lavage of patients with obstructive pulmonary disease.
