RESUMO
INTRODUCTION: This study reports the incidence, anatomic location, and outcomes of graft-vs-host disease (GVHD) at a single active intestine transplant center. METHODS: Records were reviewed for all patients receiving an intestine transplant from 2003 to 2015. Pathology reports and pharmacy records were reviewed to establish the diagnosis, location, and therapeutic interventions for GVHD. RESULTS: A total of 236 intestine transplants were performed during the study period, with 37 patients (16%) developing GVHD. The median time to onset of disease was 83 days, with 89% of affected patients diagnosed in the first year post-transplant. Mortality for affected patients was 54% in the 1 year after GVHD diagnosis. Skin lesions were the most common manifestation of GVHD. Other sites of disease included lungs, bone marrow, oral mucosa, large intestine, and brain. The incidence of GVHD was 16% in adult patients, and slightly lower in pediatric recipients (13%). In adults, increasing graft volume (isolated vs multi-organ) and liver inclusion were associated with increasing risk of GVHD, though this was not seen in pediatric patients. CONCLUSION: Overall, 16% of intestine transplant recipients developed GVHD. GVHD is associated with high mortality, and disease in the lungs, brain, and bone marrow was universally fatal.
