    Abstract:
    BACKGROUND AND AIMS: Chronic rejection (CR) is an uncommon but important cause of graft dysfunction, leading to graft loss and often requires retransplantation. This study evaluates the incidence and outcome of the patients with CR at a large living donor liver transplant (LDLT) center. METHODS: Data of patients with CR were retrospectively analyzed in 1232 adult (age >18 years) LDLT on tacrolimus (mainly)-based immunosuppression. Sirolimus/everolimus (mammalian target of rapamycin [mTOR] inhibitors) was added to baseline immunosuppression as rescue therapy in patients with CR. Data are shown as median (interquartile range [IQR]). RESULTS: Twenty-three patients (22 males), aged 42 (IQR 45-56) years, had biopsy-proven chronic rejection at 21 (8-44) months after liver transplantation. The incidence of chronic rejection was 1.9% in this cohort. The patients with CR (n = 23) had a significantly higher incidence of cytomegalovirus (CMV) viremia, acute cellular rejection, and history of anastomotic biliary strictures as compared to patients without CR. Five patients were noncompliant with immunosuppression before the diagnosis of CR. Twelve patients (52%) responded to addition of mTOR inhibitors, whereas 11 did not respond and had poor outcome. CONCLUSION: The incidence of chronic rejection is low in LDLT. Treatment with mTOR inhibitors can reverse graft dysfunction in approximately half of the patients.
