NCT06931899

Brief Summary

The objective of this observational study is to determine the effectiveness of inhaled corticosteroids in patients with chronic obstructive pulmonary disease (COPD) and frequent worsening of their respiratory symptoms by using a device called an oscillometer. This instrument is capable of measuring bronchial obstruction and air trapping in the lungs through vibrations during normal breathing. The main question it seeks to answer is: Could oscillometry be useful in assessing the effectiveness of inhaled corticosteroids in patients with COPD exacerbations, in terms of bronchial obstruction and air trapping in the lungs? Patients who choose to participate will undergo oscillometry testing and complete standard COPD questionnaires during three follow-up visits spread over three months.

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients with exacerbating COPD from the pulmonology clinics of 6 hospitals in Catalonia, Spain.

You may qualify if:

  • Age over 18 years.
  • Diagnosis of COPD.
  • Severe-moderate COPD measured by FEV1 and stable.
  • COPD exacerbations (COPD exacerbations).
  • Blood eosinophils \>100 cells/mL in prior laboratory tests.
  • Patient agrees to participate in the study and signs the informed consent form.

You may not qualify if:

  • COPD in the last 4 weeks, with use of antibiotics or systemic corticosteroids.
  • Chronic lung disease other than COPD.
  • Severe heart failure, with frequent decompensation (in cases of mild decompensation or onset without severe heart disease, do not include the patient within 3 months of decompensation).
  • Active neoplastic processes.
  • Severe renal failure.
  • \. ALT greater than 2.5 times the upper limit of normal. 6. Poorly controlled insulin-dependent diabetes or involvement of 1 or more organs.
  • \. Positive COVID-19 test (do not include until 3 months after diagnosis by ART or COVID-19 PCR).
  • \. Previous treatment with ICS in the last 4 months.
