Relationship between response to exercise and allergy in patients with cystic fibrosis.

Responses to treadmill exercise of 36 patients with cystic fibrosis were studied 
to evaluate their usefulness in identifying those with atopy. Ten of 
36 patients with cystic fibrosis (28%) had an abnormal response to 
exercise but had no more frequent atopic characteristics than those who 
had normal exercise responses. Response to treadmill exercise alone cannot identify 
patients with atopic disease among those with cystic fibrosis.
