Detaljeret beskrivelse
Low altitude baseline measurements will be performed in Bishkek. Participants will then either be assigned to a rehabilitation program in Bishkek (760m) or in Tuja Ashu (3200m).
The rehabilitation programs in high or low altitude will be identically performed and will comprise
- asthma education and awareness
- instruction on inhaled therapies
- smoking cessation counseling
- respiratory and skeletal muscle training in groups
- guided walks / cycle ergometer training
- questionnaires on asthma control, quality of life
- spirometry and peak flow measurements
- echocardiography
Measurement on study subjects will be performed at baseline (Bishkek), during the rehabilitation program, after completion of the rehabilitation program and during a follow-up at week 15.

Beskrivelse
Inclusion Criteria:
- diagnosed with atopic or non-atopic Asthma for at least 3 months
- partly controlled on regular or on demand inhaled therapy according to guidelines.
- asthma variability in peak expiratory flow > 10%/day and/or a reversible airflow obstruction in spirometry
- History of asthma consisting of variable symptoms (cough, dyspnea, wheezing).
Exclusion Criteria:
- Unstable and severely uncontrolled asthma needing systemic corticosteroids.
- Need of continuous oral steroids for their asthma control
- Heavy smokers (>20 cigarettes per day)
- Severe concomitant diseases preventing patients to adhere to the protocol and/or altitude exposure (severe metabolic, kidney- or liver disease, heart failure (ejection fracture <50%).
- Chronic lung diseases with a persistent FVC < 60% an/or arterial oxygen saturation <92%).
- Severe mental- or musculoskeletal disorders
- Pregnant or breast feeding women
- Patient which are unable to comply with the study procedure.
