title: IgG antibodies and early intradermal reactions to hydrocortisone in patients with cutaneous delayed-type hypersensitivity to hydrocortisone.
abstract: Seven of 25 patients with cutaneous delayed-type hypersensitivity to hydrocortisone had an immediate reaction following the intradermal injection of hydrocortisone sodium succinate. Using an ELISA method, we found that these patients had significantly increased levels of IgG antibodies to hydrocortisone when compared with normal blood donors (P < 0.005) and nickel-allergic patients (P < 0.05). We suggest that these patients are at risk of developing type III and possibly type I reactions following the systemic administration of hydrocortisone and that, if needed, an alternative systemic corticosteroid should be used, for example betamethasone or dexamethasone.
