Crohn's disease complicated by relapsed extranodal Hodgkin's lymphoma: prolonged complete remission after unmanipulated PBPC autotransplant.

ABSTRACT

Crohn's disease and ulcerative colitis are inflammatory bowel diseases (IBD), which are thought to result from an inappropriate immunologic (autoimmune) response to luminal antibodies. Allogeneic stem cell transplantation (SCT) performed for coincidental diseases is able to cure both leukaemia and Crohn's disease. Autologous SCT is currently performed worldwide for severe autoimmune diseases (SADs) because of its reduced transplant-related mortality (TRM). We report the case of a 30-year-old male patient with a 10-year history of severe Crohn's disease, who developed Hodgkin's disease and received an unmanipulated peripheral blood autologous transplant. Three years after the transplant the patient is in complete treatment-free remission of both diseases.
