title: Recurrent spontaneous gastrointestinal graft-versus-host disease in autologous hematopoietic stem cell transplantation.
abstract: Acute graft-versus-host disease (GVHD) is a major complication after allogeneic stem cell transplantation (SCT). A similar manifestation involving skin, gastrointestinal (GI) mucosa, and liver can occur after autologous hematopoietic SCT (autoHSCT), either spontaneously or after treatment with cyclosporine or interferon. Severity of spontaneous GI GVHD among patients treated with autoHSCT is variable. Recurrent spontaneous GI GVHD induced by succeeding cycles of chemotherapy has rarely been reported and is poorly understood. Enteric-coated budesonide has been studied extensively in Crohn's disease, and beclomethasone has been studied in GI GVHD. There are no comparative studies between these drugs for GI GVHD. Furthermore, GI GVHD has to be considered when microbiologic workup remains negative during the workup of persistent diarrhea in autoHSCT. Endoscopic appearances can be normal, and pathologic diagnosis is essential. Further research into risk factors involving type of chemotherapy, interval between chemotherapies, and gene polymorphisms have to be considered for better understanding of autologous GVHD. We report for the first time a patient with spontaneous recurrent GI GVHD after autoHSCT for multiple myeloma with predominant lower GI symptoms and excellent response to enteric-coated budesonide therapy.
