Early but not late allograft nephrectomy reduces allosensitization after transplant failure
Bibliographic record
Abstract
INTRODUCTION: Allosensitization is a significant obstacle to retransplantation for patients with primary renal graft failure. METHODS: We assessed the impact of allograft nephrectomy (Group I) and weaning of immunosuppression (Group II) on percent panel reactive antibody (%PRA) at various time points after graft failure in 132 patients with a median follow-up of 47 months. Of these, 68% had allograft nephrectomy while 32% were placed on the waiting list and were either taken off immunosuppression, left on prednisone or on low-dose immunosuppressive therapy. RESULTS: When groups were stratified into early (<6 months) and late (>6 months) graft failure, patients who had transplant nephrectomy for early failure demonstrated a decline in %PRA from 46% at time of graft failure to 27% at last follow-up (p = 0.02); conversely, %PRA continued to rise in Group II experiencing early allograft failure. Both Groups I and II patients with late graft failure maintained elevated %PRA at last follow-up. CONCLUSION: Allograft nephrectomy may play a role in limiting allosensitization in patients with early but not late graft failures.

How this classification was reachedexpand
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.
