NCT03788057

Brief Summary

A prospective, observational, interventional, single-blind study (blinded for a clinician in the field of inflammatory parameters). The aim of the study is evaluation of the usefulness of induced sputum eosinophilia and other inflammatory indices \[exhaled nitric oxide (NO), exhaled breath temperature, bronchial hyperresponsiveness\] in predicting the failure of treatment reduction with inhaled corticosteroids (ICS) in stable asthma in children and adolescents. In participants with a stable course of the asthma (confirmed in the run -in period), every 3 months the dose of ICS is halved (according to GINA guidelines) until the control is lost or the lowest daily ICS dose is reached (200 mcg, calculated as budesonide equivalent). Throughout the treatment reduction period, the participants run an observation card (clinical symptoms) and peak expiratory flow rate (PEFR) measurements. Clinical evaluation is performed every month, with spirometry, exhaled NO and exhaled breath temperature measurements. Before the reduction and then one month after the change of treatment, the hyperresponsiveness measurement is carried out with the sputum induction (combined method using hypertonic saline), and 2 months after the change of treatment with the exercise challenge test. In the case of loss of asthma control, beta-mimetic will be administered (temporarily) and return to dose of ICS before reduction or further increase of treatment is planned. In severe asthma exacerbations, oral steroids will be considered. The study is observational: treatment is modified according to GINA guidelines based on clinical data as part of routine medical care. Only difference compared do standard care is supplementary inflammation evaluation (exhaled NO, sputum eosinophilia, bronchial hyperreactivity).

Outcome Measures

Primary Outcomes (1)

    at 1, 3, 4, 6 and 7 month

Other Outcomes (7)

  • Change in Airway Hyperresponsiveness to Hypertonic Saline

    at 1, 3, 4, 6 and 7 month

  • Change in Airway Hyperresponsiveness (Exercise)

    at 2, 5 and 8 month

  • Change in Exhaled NO

    months 1 - 8

  • +4 more other outcomes

Study Arms (1)

stable asthma

OTHER

In patients with previously stable course of the asthma, every 3 months the symptoms are evaluated and the dose of ICS is customized - in accordance with the GINA guidelines. This decision is based solely on clinical data (control of symptoms) and is the same as in patients not participating in the study. In patients participating in the study, inflammatory parameters are also measured (sputum eosinophilia, eNO, EBT, bronchial reactivity), but results are not known to clinician taking decision about possible ICS dose reduction.

Other: ICS dose reduction

Interventions

If control of symptoms is maintained (evaluation based on clinical symptoms solely), every 3 months the dose of ICS is halved according to GINA guidelines, until the control is lost or the lowest daily dose is reached (200 mcg, calculated as budesonide equivalent). In the case of loss of asthma control, beta-mimetic will be administered (temporarily) and return to the chronic administration of the previous, twice higher dose of ICS is restored (or further increase of treatment). In severe exacerbations, inclusion of oral steroids will be considered.
