[The intensity of bronchial hyperreactivity and the evolution of pulmonary function].

Abstract

The relationship between the degree of the bronchial hyperreactivity (BH) and evolution or prognosis of the bronchial asthma is determined in this prospective study. BH has been examined in 108 asthmatic children and after a long period of time (average 5.5 years), the pulmonary function (VC, FEV1, FEF25-75, Raw, IGV, RV/TLC, flow-volume curve was evaluated. Impaired pulmonary function was found not to correlate with the degree of the BH. It is concluded that the degree of the BH might predict the evolution and the prognosis of the bronchial asthma.
