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).

Study Arms (1)
stable asthma
OTHERIn 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.
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.
Eligibility Criteria
You may qualify if:
- mild or moderate asthma with a stable course of at least 3 months:
- symptoms less than 4x per week,
- use of SABA below 3x a week,
- night awakening below 1x per week,
- FEV1\> 80% of predicted
- no dose change in ICS or use of systemic steroids from 3 months
- good adherence to treatment
You may not qualify if:
- infection or exacerbation of asthma requiring the use of systemic steroids (or changes in the dose of inhaled steroids) in the last 3 months before the study
- other chronic lung diseases or general diseases affecting the respiratory system
- tobacco smoking
- FEV1 below 80% of the predicted value
