Abstract:

Objective To investigate the usage of immunosuppressive agents after liver retransplantation.Methods The clinical data of 54 adult liver retransplantation patients were retrospectively analyzed. According to the application of immunosuppressive regimen，the patients were divided into 4 groups ：①corticosteroid + basiliximab + tacrolimus + mycophenolic acid（MPA）quadruple immunosuppressive regimen ；② corticosteroid + basiliximab + tacrolimus triple immunosuppressive regimen ；③ basiliximab + tacrolimus + MPA triple immunosuppressive regimen ；④ basiliximab + tacrolimus two immunosuppressive regimen. Cases of acute rejection and infection were calculated andprognosis was

recorded. Results Among 54 patients who underwent liver retransplantation，15 patients died in 1 year after surgery，and the remaining 39 patients survived for a long time. There were 9 cases（16.7%）with acute rejection and 34 cases（63.0%）with infection with in 1 year after operation. Among them，there were 31 patients in protocol 1，and 4 out of 31 had acute rejection（12.9%），20 cases had postoperative infections（64.5%）. There were 15 patients in protocol 2，and 3 out of 15 hadacute rejection（20.0%）and 10 cases had postoperative infections（66.7%）; There were only 1 case in protocol 3，there was no acute convulsion（0%），1 case had postoperative infection（100%）; And there were 7 patients in protocol 4，2 out of 7 had acute rejection（28.6%），3 cases occurred postoperative infection（42.9%）. All the cases with acute rejection were relieved after increasing the dose of tacrolimus or the treatment with methylprednisolone. A total number of 12 infected patients died of infection，and the remaining 22 patients improved after anti-infective treatment. Conclusion The immune status of patients after liver retransplantation is complicated，and individualized immunosuppressive therapy is essential.
