[Effective infliximab treatment for a recurrent type of acute intestinal graft-versus-host disease accompanied by steroid-induced depression].

A 22-year-old man with chronic active Epstein-Barr virus infection underwent allogeneic bone marrow transplantation (allo-BMT) from an HLA two allele-mismatched unrelated donor. Ten months after allo-BMT, he developed protein-losing enteropathy following a respiratory syncytial virus infection. A diagnosis of a recurrent type of acute graft-versus-host disease (GVHD) was made based on the histopathological findings, such as the infiltration of T lymphocytes into the superficial epithelium and crypts, and apoptotic bodies in crypts. Although methylprednisolone (mPSL: 10 mg/kg) administration for two consecutive days improved gastrointestinal symptoms, acute pancreatitis and severe depression developed in association with corticosteroid treatment. Reduction of mPSL and administration of infliximab (5 mg/kg/dose, 3 times) resulted in rapid improvement of depression and pancreatitis without aggravating intestinal GVHD. Recent studies have demonstrated that tumor-necrosis-factor (TNF)-α is associated with not only GVHD but also depression and acute pancreatitis. In the present case, anti-TNF-α treatment enabled us to reduce corticosteroid dose without aggravating GVHD, which suggests that this approach might be effective for the treatment of depression and acute pancreatitis.
