Objective: To assess the immune status of auxiliary liver transplantation and to clarify the immune protection of auxiliary liver to other allograft.
Methods: Immunological markers and pathological changes in 3 patients undergoing auxiliary liver transplantation were analysed.
Results: The lower the concentration of immunosuppressive agent, the less the rejection and the milder the intensity in the 3 patients. The function of allograft after auxiliary liver transplantation was excellent.
Conclusions: Patients are in a low immune reaction state after auxiliary liver transplantation. Auxiliary liver can protect other allografts by related immunological mechanisms. The side-effects of low-concentration immunosuppressive agents on auxiliary liver and other allografts are mild.
