Show more >The aims of this study were to determine whether tubulointerstitial damage in the form of interstitial fibrosis/tubular atrophy and total interstitial inflammation predicted progression to end stage renal disease (ESRD) and/or renal relapse (RR) in patients with antineutrophil cytoplasmic antibody-associated vasculitis (AAV). One hundred thirteen patients with AAV from six French centers with an index biopsy performed between 2003 and 2013 were included. Histological assessments using the AAV glomerular classification and the kidney allograft Banff classification were performed on pathological review. Biopsy tissues were also investigated by CD3, CD20, CD68, CD163, FOXP3 and RORγt immunohistochemical staining. Competing risks models were calculated. Of the 113 patients, 26 (23.0%) died during follow-up and 29 (25.6%) developed ESRD. Among the 94 patients who achieved remission by the end of induction therapy without developing ESRD, 26 (27.6%) experienced RR. The two independent prognostic factors for ESRD were the estimated glomerular filtration rate at presentation (HR 0.35; 95% CI 0.23–0.51; P < 0.0001) and IF/TA > 25% (HR 2.27; 95% CI 1.18–4.37; P = 0.014). When the distribution of interstitial immune cell phenotypes was included in a second multivariable model, the organization of lymphocytic infiltrates was also an independent predictor of ESRD (HR 2.86; 95% CI 1.35–6.1, P = 0.006). The independent risk factors for RR were a higher CD3/CD20 ratio (HR 1.39; 95% CI 1.05–1.85; P = 0.02) and the presence of RORγt positive cells (HR 2.70; 95% CI 1.11–6.54; P = 0.02). Our results highlight the prognostic value of initial histological evaluations in AAV. Measurements of tubulointerstitial damage and interstitial immune cell phenotype distributions should be considered to improve risk assessments for ESRD and RR.Show less >
