Abstract
The significance of intrinsic asthma as a diagnosis has been questioned since, except for the lack of evidence of allergy, there is no pathophysiologic distinction from extrinsic asthma. Following a standardized exercise stress, allergic extrinsic asthmatics respond with more severe asthma than do nonallergic intrinsic asthmatics. The incidence of significant exercise induced asthma is greater in a group of extrinsic asthmatics than in intrinsic asthmatics. Extrinsic asthmatics show increased airway sensitivity during a significant pollen season.
