Beskrivelse
Inclusion Criteria: Eligible patients include any patient maintained on triple therapy with tacrolimus, mycophenolate mofetil ,and prednisone who has had no prior rejection episodes and who has undergone a 6 month management kidney biopsy that shows no evidence of acute cellular rejection or antibody mediated rejection.
Exclusion Criteria: Any patient not maintained on triple therapy with tacrolimus, mycophenolate mofetil and steroids and/or who had evidence of rejection on 6- month management biopsy.

Eksperimentell: Dose adjust group (NFAT)
Within 4 weeks of a 6 month management biopsy, if eligibility is confirmed, NFAT dependent cytokines including IL-2, IFNg, and GMCSF at times C0 and C1.5 will be performed with the residual expression calculated based on the ratio of C1.5/C0 x 100%.
If the average residual expression of the 3 cytokines is <20%, the CNI daily dose will be reduced by 15%.
If the average residual gene expression of the 3 cytokines is > 60% the CNI daily dose will be increased by 15%.

Ingen inngripen: Standard of care group
A CNI trough level will be obtained.
Adjustments of CNI will be based on target trough drug levels as per standard of care.
