Tacrolimus (TAC) is the most important immunosuppressants for maintenance therapy after kidney transplantation. Many genetic and clinical factors had been found to have effect on TAC pharmacokinetics (PK). Whether these factors affect clinical outcomes is still controversial.~In this retrospective study, investigators will review records of kidney transplant patients with TAC based immunosuppression recruited from a previous study (IRB approval number: 201512005RINC) to understand the influence of clinical and genetic factors on their 3-years clinical outcomes, including biopsy-proven acute rejection, patient survival, graft survival and safety issues of kidney transplant patients.
The purpose of this study is to identify the influence of genetic and clinical factors on the clinical outcomes of kidney transplant patients with tacrolimus (TAC) based immunosuppression in Taiwan.
