Diagnosis and treatment of acute graft-versus-host disease after liver transplantation: A report of 11cases.

OBJECTIVE

This study aims to summarize a clinical experience on the diagnosis and treatment of acute graft-versus-host disease (aGVHD) after liver transplantation.

METHODS

Between April 2005 and August 2016, 11 recipients who underwent OLT developed aGVHD with clinical symptoms of fever, rash, diarrhea and pancytopenia. T lymphocyte chimerism was detected though STR-PCR. These patients were treated with immunosuppressant adjustment, methylprednisolone, basiliximab, etc. All the results were recorded and summarized.

RESULTS

We demonstrated the diagnostic criteria of aGVHD based on our experiences: 1 aGVHD occurred from two weeks to two months after the liver transplantation. Fever, rash, digestive tract symptoms and bone marrow suppression were the four symptoms that appeared in any orde, All the percentages of donor T lymphocytes of aGVHD patients were more than 10%. All 11 recipients underwent treatments including immunosuppressant adjustment, glucocorticoids, IVIG and organ function support. Among these recipients, two survived due to successful treatment, while nine recipients died due to infection and cerebral and digestive tract hemorrhage. It is noteworthy that the occurrence of aGVHD was related to the dose of immunosuppressive agents, and we suggest the concept of "aGVHD induced by immunosuppression".

CONCLUSIONS

The diagnostic criteria of aGVHD is mainly based on time, clinical symptoms, T-lymphocyte chimerism and histopathology. The concept of "aGVHD induced by immunosuppression" provides important guidance in immunosuppressant management, control, and prevention of infection. Support treatment is very important in the treatment of aGVHD.
