Intra‐arterial methylprednisolone for severe steroid refractory gastrointestinal graft‐versus‐host disease

Acute graft versus host disease (GVHD) is a significant complication of bone marrow transplantation with approximately half of patients being refractory to steroids. There are numerous second‐line systemic immunosuppressive treatments but the overall prognosis is poor and these therapies are associated with high mortality due to infection. An alternative approach to systemic treatment for GVHD is targeted delivery of immunosuppression. We present two pediatric cases with steroid‐refractory gastrointestinal GVHD who clinically responded to intra‐arterial steroid administration. We also review the literature regarding this treatment modality with a particular emphasis in children. Pediatr Blood Cancer 2014;61:2321–2323. © 2014 Wiley Periodicals, Inc.
