Impact of cyclosporine 2‐h level and mycophenolate mofetil dose on clinical outcomes in<i>de novo</i>heart transplant patients receiving anti‐thymocyte globulin induction
Bibliographic record
Abstract
BACKGROUND: Cyclosporine (CsA) 2-h post-dose level (C2) correlates better than trough levels (C0) with the area under the curve. We evaluated the clinical impact of C2 and mycophenolate mofetil (MMF) dose in adult heart transplant patients receiving anti-thymocyte globulin (ATG) induction. METHODS: Two immunosuppressive strategies were sequentially evaluated. In Group 1 (13 patients), simultaneous C0/C2 (ng/mL) were analyzed. CsA dose monitoring was initially based on C0 : <3 months: 200-300, 4-6 months: 150-250, 6-9 months: 100-200, and on C2 thereafter (as in Group 2). In Group 2 (nine patients), C2 monitoring was implemented: <3 months: 600-800, 4-6 months: 500-700, >6 months: 400-600. All patients received ATG induction, corticosteroids, and MMF (1.0 g b.i.d. in Group 1 and 1.5 g b.i.d. in Group 2). RESULTS: Patients in Group 2 received higher MMF doses during the first trimester. C2 at 1, 3, 6, 12, 24, and 36 months was, respectively, 1199 +/- 476, 1202 +/- 587, 999 +/- 467, 664 +/- 203, 593 +/- 208, and 561 +/- 147 in Group 1, and 809 +/- 160 (p = 0.02), 644 +/- 178 (p = 0.003), 664 +/- 169 (p = 0.02), 616 +/- 221, 464 +/- 234, and 451 +/- 165 in Group 2. The incidence of acute rejection (grade > or =3A) at 6, 12, 24, and 36 months was, respectively, 38.5, 38.5, 46, and 54% in Group 1, and 11, 44, 56, and 56% in Group 2 (p = NS). At 3 months, the creatinine clearance was 25% lower in Group 1. Thereafter, renal function remained stable in both groups. CONCLUSION: Our results suggest that heart transplant patients receiving ATG induction may experience similar outcomes with either a higher C2 and a lower MMF dose or a lower C2 and a higher MMF dose. These results could be considered to design prospective studies to optimize C2 monitoring, to reduce the incidence of acute rejection without increasing the risk of 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.
