Delayed generalized allergic reactions to corticosteroids

A 37-year-old patient presented with a severe allergic local reaction upon inhalation of budesonide for asthma. Skin tests were positive for budesonide and amcinonide (group B) and elicited a strong local reaction and a disseminated macular exanthema. Corticosteroids from other groups were well tolerated. A 38-year-old male patient had first an allergic contact dermatitis to topically applied prednisolone acetate and then a disseminated eczematous exanthema upon oral intake of prednisone. A delayed-type sensitization to corticosteroids from group A such as hydrocortisone, prednisone and tixocortol pivalate was identified. A detailed diagnosis in patients with allergic reactions to corticosteroids is crucial with regard to their use in emergency therapy. (C) 2000 S. Karger AG, Basel.
