Should asthma management include sojourns at high altitude?

Area of Science:

• Pulmonology
• Environmental Medicine
• Clinical Therapeutics

Background:

• High-altitude sojourns have a long history of recommendation for asthma management.
• Early 20th-century observations indicated significant asthma symptom improvement in alpine climates.
• Modern healthcare systems increasingly question the efficacy of high-altitude asthma treatment.

Purpose of the Study:

• To review existing data on the effects of high-altitude stays (1,500-1,800m) for asthma patients.
• To evaluate the therapeutic value of alpine environments for bronchial asthma.
• To address the current skepticism regarding high-altitude asthma therapy.

Main Methods:

• Literature review of studies on asthmatic patients residing at high altitudes.
• Analysis of historical physician inquiries regarding asthma prevalence and severity in alpine regions.
• Synthesis of evidence on the impact of altitude on asthma control and symptom frequency.

Main Results:

• Historical data (1906) showed 133/143 asthma patients experienced few or no attacks in Davos.
• A significant majority (81%) reported persistent improvement in their asthma condition.
• Current evidence supports a beneficial effect of high altitude on bronchial asthma, particularly for steroid-dependent cases.

Conclusions:

• High-altitude environments demonstrate a significant positive impact on bronchial asthma.
• The therapeutic benefits are particularly notable in patients requiring steroid therapy.
• Further research and validation are needed to support high-altitude therapy against modern skepticism.
