Allergic sensitization due to corticosteroids seldom occur and are compound-specific, as a rule. They induce various clinical features, in particular urticaria, different exanthematous reactions and contact dermatitis as shown by our observations in 10 patients with prednisolone-allergy. In three cases a simultaneous allergy due to methylprednisolone was found. Impairment of the features or alterations in the clinical morphology after the application of prednisolone suggest the diagnosis, which can be confirmed by means of the scratch and epicutaneous testing and in one patient by the oral exposure, additionally. In addition a delayed-type sensitization to propylene glycol could be proved in three cases, and the same was with romulgin and parabens in one case each. Dexamethasone was used and tolerated as alternative and emergency medication in equivalent doses.

A 29-year-old Chinese female was diagnosed with chronic urticaria. Dexamethasone and gamma globulin initially resolved the illness; however, when dexamethasone was decreased and gamma globulin was withdrawn, urticaria emerged again and could not be controlled by any of the medications used. The diagnosis of refractory chronic urticaria was made and double-filtration plasmapheresis (DFPP) was performed. The symptoms were relieved during the first DFPP procedure and the disease resolved shortly thereafter. DFPP theoretically removes medium to large molecular substances such as IgG and IgE from circulation, and therefore may prove to be an effective treatment for refractory chronic urticaria.
