Outcomes of Renal Transplantation in ANCA-Associated Vasculitis
Bibliographic record
Abstract
BACKGROUND Antineutrophil cytoplasmic antibody-associated vasculitis is characterized by small-vessel inflammation and ANCA-positive serology that often lead to end-stage kidney disease. This study investigated the outcomes of renal transplantation in patients with antineutrophil cytoplasmic antibody-associated vasculitis. MATERIAL AND METHODS A comprehensive search of PubMed, Scopus, and Embase databases was done to retrieve studies that reported on the outcomes of renal transplantation in these patients. Data on mortality, survival, infection, and relapse rates were analyzed. The quality of the included studies was evaluated using the Newcastle-Ottawa Scale for cohort studies. RESULTS Twenty-three retrospective cohort studies were included in this review. Antineutrophil cytoplasmic antibody-associated vasculitis was associated with high post-transplantation mortality rates, with a pooled rate ratio of 11.99 per 100 patient-years, but relatively favorable survival rate (hazard rate of 0.80). After renal transplantation, these patients had elevated infection rates (pooled rate ratio of 52.70 per 100 patient-years), and high risk of relapse (pooled rate ratio of 6.96), emphasizing the importance of vigilant post-transplantation monitoring. CONCLUSIONS End-stage kidney disease patients with vasculitis, undergoing renal transplantation, are at elevated risk of mortality and postoperative infection compared to patients without antineutrophil cytoplasmic antibody-associated vasculitis. The risk of relapse is also high in these patients. However, renal transplantation offers a survival advantage for vasculitis patients who survive the early post-transplantation period.

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.
