title: Treatment of edema disease of swine.
abstract: Antihistamine (Allermin) was used sucessfully in the treatment of naturally occurring edema disease of swine under the field and laboratory conditions. A high recovery rate (88.8%) was obtained in the group of pigs with mild clinical signs. The intravenous route of Allermin administration had definite beneficial value. The release of histamine induced by circulating immune-complexes may be responsible for the clinical signs characteristic of edema disease. Three pigs that recovered clinically following the Allermin treatment were examined histologically. Fibrinoid persisted in the vascular walls at least 30 days after the initiation of the treatment. The fibrinoid vasculitis, generalized eosinophilia at the tissue level, and favorable response of pigs to antihistamine treatment suggest that edema disease may be caused by allergy.
