Calcineurin inhibitor substitution with sirolimus vs. reduced‐dose calcineurin inhibitor plus sirolimus is associated with improved renal dysfunction in heart transplant patients
Bibliographic record
Abstract
Heart transplant (HTx) patients are at risk of developing renal dysfunction. Sirolimus has been used as an alternative for calcineurin inhibitors (CNI) in transplant patients with renal dysfunction. Recent data suggest that the combination of sirolimus with a CNI is associated with a deterioration of renal function in renal transplant patients. The purpose of the present study was to compare the effect on the creatinine clearance (CrCl) of heart transplant (HTx) patients with renal dysfunction (RD) on CNI-based sirolimus-free regimens of conversion to either reduced-dose CNI plus sirolimus or outright substitution of CNI with sirolimus. We retrospectively identified 29 treatment switches for 26 patients with RD defined as a decline in the CrCl > 25% post-HTx. Treatment switches were divided into two groups. Group 1 included 13 switches in 13 patients (four women, nine men, age 62 +/- 10 yr) in whom sirolimus replaced CNI. Group 2 included 16 switches in 15 patients [two women, 13 men (one man underwent two such switches), age 61 +/- 9 yr] in whom CNI dose was reduced and sirolimus was added. Two men appear in both groups. Average follow-up was 10.4 +/- 3.2 months. Overall mortality, rejection, and side-effects rates were comparable between groups. At 12-months post-switch, the mean CrCl had increased from 48 +/- 15 at time of treatment switch to 56 +/- 22 mL/min in group 1 and decreased from 53 +/- 19 to 47 +/- 17 mL/min in group 2 (p = 0.02). In conclusion, substitution of CNI with sirolimus provided improved renal recovery compared with lower-dose CNI plus sirolimus in HTx patients with renal dysfunction.

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.
