Our study aimed to assess whether incorporating recently identified predictors of kidney survival in AAV could further refine the prognostic accuracy of AKRiS in our multicentric cohort.</p><p><strong>Methods: </strong>We retrospectively reviewed all incident AAV with kidney biopsy from 2005 to 2020. Cox regression analysis examined factors [AKRiS, dialysis within 4 weeks, urine protein-creatinine ratio (UPCR) and hematuria at baseline, C3 deposits, renal arteritis on biopsy, estimated glomerular filtration rate (eGFR), UPCR and hematuria after induction] associated with kidney failure. These factors in combination with AKRiS were analyzed using the area under the receiver operating characteristic curve (AUROC) for prediction of kidney failure.</p><p><strong>Results: </strong>The cohort included 115 patients (age 64 years, 55% male, 57% myeloperoxidase-ANCA, baseline creatinine 3.6 mg/dL, eGFR 16 mL/min/1.73 m<sup>2</sup>), with 34 (30%) dialysed within 4 weeks. During a median 6.4-year follow-up, 39 (34%) patients progressed to kidney failure, and 13 (11%) died. Cox analysis identified AKRiS, dialysis within 4 weeks, C3 deposits, renal arteritis on biopsy, lower eGFR after induction and higher UPCR after induction as unadjusted risk factors for kidney failure. After adjusting for AKRiS, dialysis within 4 weeks [hazard ratio (HR) 6.20 (95% confidence interval 2.76 to 13.95), <i>P</i> ≤ .001], eGFR after induction [HR 0.94 (0.89 to 0.99), <i>P </i>= .03] and UPCR after induction [HR 1.62 (1.02 to 2.58), <i>P </i>= .04] remained significantly associated with kidney outcome. The AUROC for kidney failure prediction was 0.77 for AKRiS, increasing to 0.82, 0.80 and 0.79 when adding dialysis within 4 weeks, eGFR and UPCR after induction, respectively.</p><p><strong>Conclusion: </strong>Dialysis within 4 weeks, eGFR after induction and UPCR after induction are able to predict long-term kidney outcome in AAV patients. Adjusting AKRiS for these variables modestly enhances its predictive power. We propose using them as placeholder endpoints for kidney failure in future studies.</p>","PeriodicalId":10435,"journal":{"name":"Clinical Kidney Journal","volume":"18 9","pages":"sfaf268"},"PeriodicalIF":4.6,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12451443/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145130177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
