Methylprednisolone-Induced Hypersensitivity Reaction in a Liver Transplant Recipient.

Corticosteroids have an essential role as an immunosuppressive agent in transplant; because of their anti-inflammatory properties, they rarely cause an allergic reaction. Here, we report a liver transplant recipient who developed an allergic reaction to intravenous methylprednisolone sodium succinate. The deceased-donor orthotopic liver transplant recipient received intravenous methylprednisolone sodium succinate for induction during transplant, which was followed by another intravenous dose and oral prednisone taper. She was later treated with intravenous methylprednisolone sodium succinate taper for acute cellular rejection, which had been confirmed with a second biopsy. After admission for further treatment, she received another 1 g of intravenous methylprednisolone sodium succinate dose. About 15 to 20 minutes after receiving this dose, she presented with a new-onset urticarial rash that started on the trunk and progressed with facial edema. She continued a course of intravenous and oral dexamethasone for treatment of rejection and later was restarted on and tolerated oral prednisone. This case highlights the importance and the possibility of using dexamethasone as an alternative treatment approach for those with similar reactions to intravenous methylprednisolone sodium succinate.
