Detection of contact hypersensitivity to topical corticosteroids with hydrocortisone-17-butyrate.
We showed earlier that most patients with contact dermatitis due to corticosteroids show cross-reactions when patch tested with hydrocortisone-17-butyrate (H-17-B). To test whether H-17-B could be used for detecting topical corticosteroid allergy, we screened patients undergoing routine patch testing with H-17-B. Patients with clearly allergic or doubtful/mildly irritant patch test reactions to H-17-B, and with a history suggesting topical corticosteroid allergy, were further tested with a large panel of steroid preparations. 20 out of 4039 patients (0.5%) showed definite allergic test reactions to corticosteroids. A further 165 patients with clinically suspected corticosteroid allergy were directly tested with a panel of steroid preparations; 14 patients showed positive patch test reactions. Altogether, 33 out of 34 patients with corticosteroid allergy had positive test reactions to H-17-B. Inclusion of 1.0% H-17-B in ethanol in the standard patch test series improves the diagnosis of topical corticosteroid hypersensitivity.
