The aim of this observational study is to evaluate the pulmonary hyperinflation and its immediate reversibility to a short acting beta2 agonist test in uncontrolled persistent asthmatic patients with dyspnea.


Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Evaluation of the Prevalence and the Reversibility of the Lung Hyperinflation in Uncontrolled Persistent Asthmatic Patients With Dyspnea

Further study details as provided by Chiesi Farmaceutici S.p.A.:

Enrollment: 450
Study Start Date: February 2011
Study Completion Date: January 2012
Primary Completion Date: October 2011 (Final data collection date for primary outcome measure)
Detailed Description:

The other objectives are :

  • the evaluation of the hyperinflation defined by an increase of the residual volume (RV),
  • the observation of the relationship between the hyperinflation and the asthma characteristics,
  • the study of the improvement of the functional parameters after a reversibility test
  • the evaluation of the correlation between hyperinflation parameters evolution, chest tightness and dyspnea

Ages Eligible for Study:   18 Years to 90 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Inclusion Criteria:

  • Patient with a diagnosis of uncontrolled persistent asthma (ACT </= 19) or with an MRC score of dyspnea >/= 1
  • Patient requiring a check-up including a pulmonary function test by plethysmography with a reversibility test

Exclusion Criteria:

  • Patient participating to an other clinical trial or having participated to a clinical trial with medicine in the last 3 months
