Glucocorticoid Dosing and Outcomes in ANCA-Associated Vasculitis With Kidney Involvement
Bibliographic record
Abstract
Introduction: There may be reservations about the guideline-recommended use of reduced glucocorticoid (GC) therapy in severe ANCA-associated vasculitis (AAV). We examined differences in outcomes based on oral GC use during induction therapy for AAV with kidney involvement. Methods: We conducted a single-center, retrospective cohort study (2010-2023) of patients with biopsy-proven kidney involvement from AAV. Patients were divided into eras 2020 onward (reduced-GC) versus pre-2020 (standard-GC) according to practice shift after adopting a reduced-GC regimen. The primary outcome was the composite of end-stage kidney disease (ESKD) or death within 12 months postbiopsy. Secondary outcomes included serious infection, clinical remission, and change in estimated glomerular filtration rate (eGFR). Results: There were 138 participants (mean age: 65.2 years, 46.4% female, 68.1% anti-myeloperoxidase), comprising 41 in the reduced-GC era and 97in the standard-GC era. The former group was older (70.3 vs 63.1 years) and had worse baseline kidney function (eGFR: 15.6 vs 22.6 ml/min). The reduction of cumulative GC for reduced-GC compared with the standard-GC era was 39% in the first month, 28% in the first 3 months, and 34% in the first 6 months. For reduced-GC compared with standard-GC era, there was no significant difference in ESKD or death (24.4% vs. 21.6%), serious infection (14.6% vs. 17.5%), or remission (63.4% vs. 63.9%); and both groups showed similar improvement in eGFR over 12 months. Conclusion: Reduced-GC during induction therapy in individuals with organ-threatening kidney involvement was not associated with a change in outcomes or kidney function recovery. This supports data from a large, randomized trial.

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.
