Bronchial asthma due to allergy to pancreatic extract: a hazard in the treatment of cystic fibrosis.

The mother of two children suffering from cystic fibrosis developed marked allergic 
symptoms affecting the eyes, nose and bronchi and severe bronchial asthma 
ensued. The cause of this allergy proved to be the powder 
released on opening the capsules of pancreatic extract which she provided 
for her children at each mealtime. The risk of pancreatic extract 
to those handling it, and possibly also to patients suffering from 
cystic fibrosis, is emphasized.
