Abstract
Enterocolitis is common after cord blood transplantation (CBT) and a specific, non-graft-versus-host disease (GVHD) entity with specific histopathologic features ("cord colitis") has been described in some cases in selected series. Immune suppression is not without risk, and we have used it only when biopsy features are consistent with classical GVHD. In the absence of biopsy features of classical GVHD, our management of intestinal failure has been supportive, and we have withdrawn immune suppression to allow immune reconstitution and better prevent relapse of malignant disease and reduce infectious complications. We evaluated our approach over an 11-year period in a retrospective study of all patients at our large pediatric CBT center who experienced intestinal failure necessitating endoscopy and biopsy in the post-CBT period. We conducted a blinded histopathologic review of gastrointestinal (GI) biopsy specimens from all patients who had undergone GI endoscopy for intestinal failure in the post-CBT period. Patient records were evaluated to determine clinical HSCT course and outcome data, including mortality, relapse, and infection, as well as the duration of immune suppression and parenteral nutrition. Out of 144 patients who underwent CBT during the study period, 25 (17%) experienced intestinal failure requiring endoscopy. Thirteen patients were diagnosed with acute GVHD after blinded review of biopsy specimens, and 12 patients had non-GVHD enterocolitis. Management in the absence of GVHD on GI biopsy is supportive, with withdrawal of immune suppression in patients with malignant disease and continuing in accordance with institutional practice in those with nonmalignant disease. Compared with the GVHD cohort, the non-GVHD enterocolitis cohort had superior overall survival (91% versus 41%; P = .04) and a shorter duration of immune suppression (mean, 112 days versus 180 days; P = .049), reflecting these different management approaches. These results demonstrate that different histopathologic findings in those with intestinal failure after CBT likely indicates a different etiology from GVHD and mandates a different clinical management strategy to achieve optimal clinical outcomes.
