NCT03034005

Brief Summary

This study aims to assess the effect of inhaled corticosteroids (ICS) on airway smooth muscle (ASM) Na+, K+ pumps in patients with asthma.We wish to investigate differences in Na+, K+ pump content in healthy versus asthmatic patients, whether a reduction in airway hyper-responsiveness observed in asthmatic patients treated with ICS is attributable to an increase in Na+, K+ pump content in ASM cells and compare this in patients with non-eosinophilic asthma versus eosinophilic asthma.

Outcome Measures

Primary Outcomes (1)

  • Change in airway hyperresponsiveness (mannitol challenge) per change in Na+, K+ pumps content in airway smooth muscle.

    Change in PD15 per chhange in NA/K ATP'ase content

    6 weeks

Secondary Outcomes (2)

  • Change in Na+, K+ pump content in airway smooth muscle and in skeletal muscle (ρmol ouabain per g wet weight) in NEA vs. EA.

    6 weeks

  • Change in airway hyperresponsiveness (PD15 to mannitol) in NEA vs. EA

    6 weeks

Other Outcomes (4)

  • Change in asthma control score vs in Na+, K+ pumps content in airway smooth muscle.

    6 weeks

  • Change in lung function (FEV1) vs in Na+, K+ pumps content in airway smooth muscle

    6 weeks

  • Change in asthma control score in NEA vs. EA

    6 weeks

  • +1 more other outcomes
