Inhaled Steroids and Control of Severe Asthma (INHALE)
6. november 2020 opdateret af: Carmen Brittinger, University of Giessen
Inhaled Steroids and Control of Severe Asthma: Comparison of the AKITA Technology Versus Conventional MDI (INHALE)
Investigational device: AKITA 2 device versus conventional metered-dose inhaler (MDI)
Objectives: To explore if inhalative fluticasone application by means of the AKITA technology would result in a better symptom control in patients with severe persistent asthma as compared to inhalative application of fluticasone by a conventional MDI.
Study design: open label, cross-over (one AKITA, one MDI arm)
Patients: 20 Patients with severe persistent asthma

Pulmonary function tests (PFT) will be performed and lung function will be assessed by means of spirometry and body plethysmography.
|
38 weeks
|
|
Diffusing capacity for carbon monoxide
Tidsramme: 38 weeks
|
Diffusing capacity for carbon monoxide will be assessed at rest and holding breath at full inspiration.
|
38 weeks
|
|
Capillary blood gas analysis
Tidsramme: 38 weeks
|
Capillary blood gas analysis will be obtained from the arterialized ear lobe.

Measurement of Fractional Concentration of Nitric Oxide in Exhaled Air (feNO)
Tidsramme: 38 weeks
|
feNO will be assessed at each visit.
Measurements will be performed following the recommendations of the American Thoracic Society (ATS) and the European Respiratory Society (ERS).
