Study population

All renal transplant recipients between January 1, 2005 through December 31, 2014 in one of the five participating centers are included. Further selection will be undertaken to include only patients receiving oral tacrolimus as one of the main immunosuppressant at post-transplant 2 month (for early outcomes) and post-transplant 1 year (for late outcomes).

Inclusion criteria

  • Renal transplant recipients between January 1, 2005 through December 31, 2014 in one of the five participating centers
  • Patients receiving oral tacrolimus as one of the main immunosuppressant at the start of the defined cohort time (i.e. at post-transplant 2 months for the analysis of 1-year outcomes and at post-transplant 12 months for the analysis of 6-year outcomes)

Exclusion criteria

Exclusion Criteria:

  • Graft failure occurring within the first 2 month of transplantation
  • Mortality of any cause occurring within the first 2 month of transplantation
  • Patients moving centers during the study period
  • Patients who have received other organ transplantation(s) besides renal transplantation in the defined period

What researchers measure

Primary outcomes

  1. relationship between time varying periodic mean of tacrolimus trough and a composite 1-year allograft outcomes

    the relationship between time varying periodic mean of tacrolimus trough level during 2-12 mo. post-transplant and a composite of 1-year allograft outcomes consisting of biopsy proven acute rejection, renal dysfunction (eGFR\<30), development of dnDSA, and death censored graft failure that occurred within 1 year from the latest transplant.

    Time frame: 1 year after transplantation

Secondary outcomes

  1. relationship between time varying periodic mean of tacrolimus trough level during 12-72 mo. post-transplant and 6-year composite allograft outcome

    the relationship between time varying periodic mean of tacrolimus trough level during 12-72 mo. post-transplant and 6-year composite allograft outcome that occurred within 6 years from the latest transplant

    Time frame: 6 year after transplantation

  2. relationship between post-transplant time varying periodic mean tacrolimus trough level and severe infection

    the relationship between post-transplant time varying periodic mean tacrolimus trough level and severe infection (1-year and 6-year)

    Time frame: 6 year after transplantation

  3. relationship between post-transplant time varying periodic mean tacrolimus trough level and cardiovascular event

    the relationship between post-transplant time varying periodic mean tacrolimus trough level and cardiovascular event (1-year and 6-year)

    Time frame: 6 year after transplantation

  4. relationship between post-transplant time varying periodic mean tacrolimus trough level and patient mortality

    the relationship between post-transplant time varying periodic mean tacrolimus trough level and patient mortality (1-year and 6-year)

    Time frame: 6 year after transplantation
