Pulmonary function and bronchial hyperreactivity in asthmatic children with house dust mite allergy during prolonged stay in the Italian Alps (Misurina, 1756 m).

The effects of high altitude were evaluated in 14 children with allergic bronchial asthma over an 8-month period. Clinical improvement, as assessed by decreased bronchial lability, was demonstrated by pulmonary function studies. There was a decreased requirement for drugs and steroids were discontinued in our children. The results of this study suggest the use of this approach as a possible adjunct to the management of refractory cases of bronchial asthma.
