Tacrolimus therapeutic drug monitoring and pediatric renal transplant graft outcomes
Bibliographic record
Abstract
Predose monitoring of tacrolimus levels is standard practice in the care of pediatric renal transplant patients. This is despite a paucity of data investigating the ideal target range in children, and controversy as to whether tacrolimus levels correlate with renal transplant outcomes. We performed a retrospective cohort analysis of 48 renal transplant patients at a single Canadian pediatric transplant center following the initiation of a tacrolimus-mycophenolate-prednisone-based IS protocol. We analyzed the relationship of graft function, as defined by GFR up to five yr post-transplant, to the preceding mean tacrolimus level. There was no significant correlation between absolute GFR and mean tacrolimus levels (r = 0.206, p = 0.38). However, a higher mean tacrolimus level, particularly ≥10 ng/mL in the first three months after transplantation, was associated with a slower rate of decline in GFR with time (r = 0.608, p = 0.004) and with a less likelihood of developing CKD five yr after transplant. We suggest that the optimal target range for tacrolimus levels may be at the upper end of what is currently practiced and that further research to validate these findings would be useful.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
