Clinical Outcome of Liver Transplant Patients With Tacrolimus-based Immunosuppression

A great number of studies had found significant correlation between tacrolimus pharmacokinetics and gene polymorphism. However, previous studies on the correlation between genetic factors and clinical outcome were controversial. Furthermore, most studies focused on single genetic polymorphism and clinical outcome, and very limited studies took multiple genetic factors and clinical factors into account. This is a retrospective study. Eligible patients were those who had signed informed consent for genetic study in previous research projects ( IRB approval number：201512005RINC and 201612023RIND ). The present study will collect laboratory data, concurrent medications, and therapeutic drug monitoring (TDM) data. Patient survival, graft survival, acute rejection and tacrolimus-associated adverse events will be assessed.
