Immunologic responses to intravenous streptokinase in dogs.
Streptokinase is used worldwide as a thrombolytic agent. Allergic reactions to streptokinase have been reported, but the immunologic mechanisms have not been well characterized. To develop a canine model of streptokinase immune responses analogous to human responses, four dogs received intravenous streptokinase infusions. Significant rises in IgG, IgA and IgM antibody levels occurred after streptokinase administration in three of four dogs; a fourth dog developed significant increases in IgG and IgA antibody levels. Two dogs developed immediate-type cutaneous hypersensitivity to streptokinase. One dog developed subacute dermatitis with eosinophilic infiltrates which was possibly a manifestation of an allergic reaction to streptokinase.
