[Bronchoreactivity induced by physical exercise and methacholine in children with rhinitis and allergic asthma. A comparative study].
Bronchial provocation tests (TBP) allow to detect airways hyperreactivity in asthmatics. Twenty asthmatic children and sixteen rhinitics underwent a standard methacholine challenge and a free running exercise test on two separate days. Metacholine challenge pointed out bronchial hyperreactivity in 90% of the asthmatics. An exercise induced bronchospasm occurred in 70% of them. TPB resulted positive also in 18% of the rhinitics. Our study confirms diagnostic usefulness of the TBP and a good correlation between both tests.
