Graft-versus-Host Disease after Liver Transplantation: A Single-Center Case Series.

BACKGROUND: Graft versus host disease (GVHD) is a rare complication following liver transplantation (LT) and has high mortality. We describe our single-center experience with 6 cases of GVHD diagnosed over a period of 14 years in a total of 604 liver transplant recipients--283 deceased donor liver transplants (DDLT) and 321 living-related liver transplants (LDLT). CASE REPORT: We report a case series of 6 patients with acute GVHD after liver transplantation from May 2001 to December 2014. Five cases were males; age 51-67 years (average 61). The time from transplantation until clinical presentation of GVHD ranged from 36 to 140 days, with average duration of 72 days. All cases had diarrhea and pancytopenia, 4 out of 5 presented with erythematous skin rashes, and 2 had cytomegalovirus colitis. GVHD was confirmed by skin biopsies, engraftment profile from bone marrow biopsy, and sigmoid colon biopsy. Treatment strategies included use of corticosteroids in 4 cases, stopping immunosuppression in 1 case, and no treatment in 1 case with mild disease. Five patients died between 18 to 65 days from clinical presentation (average 43 days) and 1 patient with mild GVHD is doing well 290 days after clinical presentation. CONCLUSIONS: GVHD is a rare complication after liver transplantation that needs a high index of suspicion in patients who develop rash, diarrhea, or sever pancytopenia. There is no consensus on the best treatment regimen and mortality remains high.
