[Physical exercise-induced bronchospasm in asthmatic children. Clinical usefulness of the specific free-running bronchial provocation test].
Exercise-induced bronchospasm (E.I.B.) is frequently observed in children. Here are reported the correlation between E.I.B. and some clinical-anamnestical parameters found in a group of thirty-eight asthmatic children examined by exercise. The aspecific bronchial provocation test was performed with six minutes free-running. The exercise-induced bronchospasm was estimated by bronchial obstruction index (b.o.i.). All the children were tested at 4 p.m., out of attacks, without clinical signs of airway obstruction, with basal pick-flow rate (PEFR) at least 80% of predicted. We have looked for the possible correlations between E.I.B. and the following parameters: sex, exercise-induced asthma, house heating, season, period of clinical remission, length of the disease and number of attacks per year. These results indicate that bronchial provocation test with free-running is useful in asthmatic children to objectify the bronchial hyperreactivity and to follow-up the course of the disease.
