Effects of Nycthemeral Variations on Computed Tomography (CT) Parameters Reflecting Airways Remodelling, and Pulmonary Emphysema Extent in Chronic Obstructive Pulmonary Disease (COPD)

NCT01192932 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 20

Last updated 2012-07-04

No results posted yet for this study

Summary

Computed tomography (CT) studies considering bronchial dimensions in chronic obstructive pulmonary disease (COPD) have never considered nycthemeral variations. Airway calibre, in COPD patients, exhibits a nycthemeral variations with maximal values around noon and minimal values in the early morning, that persists under long-acting bronchodilator. Furthermore, no study has assessed the possible nycthemeral variations of CT scans parameters reflecting airway remodelling and emphysema extent in COPD patients.

This is a prospective study whose purpose is to assess these variations and their relationships with pulmonary function testing (PFT) in COPD patients.
