Cord Colitis Syndrome in Cord-Blood Stem-Cell Transplantation

Abstract

Diarrhea is a frequent complication of hematopoietic stem-cell transplantation (HSCT). Important causes of diarrhea after HSCT include acute graft-versus-host disease (GVHD), infections, and medications. After the transplantation and engraftment of hematopoietic stem cells from umbilical-cord blood, we observed a new syndrome of culture-negative, antibiotic-responsive diarrhea not attributable to any known cause.
