Pulmonary hypersensitivity associated with pancreatin powder exposure.
A 25-year-old woman with obstructive, reversible pulmonary and nasal hypersensitivity apparently induced by casual, repeated inhalation of pancreatin powder (desiccated pork pancreas) is described. The powder was being employed as a dietary supplement for the patient's son, diagnosed as having cystic fibrosis. Two challenges of the diagnosed as having cystic fibrosis. Two challenges of the patient by reproducing home use of the powder resulted in repetition of a hypersensitivity symptom complex on both occasions. Vitalometry demonstrated an immediate and late response. Avoidance of pancreatin powder exposure resulted in subsidence of symptoms. Immunologic mechanisms are suggested but not proven.
