PG - e13929 LID - 10.1111/ijcp.13929 [doi] AB - OBJECTIVE: Kidney involvement is a major manifestation of antineutrophil cytoplasmic antibody-associated vasculitis (AAV) and may progress to end-stage renal disease (ESRD), requiring renal replacement therapy. Unfortunately, there is no reliable kidney-specific index for predicting the progression of renal disease to ESRD. The fibrosis index (FI) reflects the degree of fibrosis in chronic liver disease. This study aimed to investigate whether the FI at the time of diagnosis could predict the development of ESRD in AAV patients. METHODS: We retrospectively reviewed the medical records of 211 immunosuppressive drug-naive AAV patients and extrapolated the cut-off FI value for predicting the development of ESRD using receiver operating characteristic curves. The associations between the FI and clinical outcomes, including mortality, relapse, and ESRD development, were determined. RESULTS: Overall, 39 (18.5%) patients developed ESRD owing to the progression of AAV-associated renal disease. The median FI was higher in AAV patients with ESRD than in those without (1.61 vs 1.04; P = .001). The FI cut-off was 1.72. The incidence of ESRD was higher in patients with FI >/= 1.72 at the time of diagnosis than in those with an FI < 1.72 at the time of diagnosis (relative risk: 4.655; 95% confidence interval: 2.242-9.662; P < .001). Kaplan-Meier survival analysis revealed that patients with an FI >/= 1.72 at the time of diagnosis exhibited significantly lower ESRD-free survival rates than those with an FI < 1.72 at the time of diagnosis (P < .001). CONCLUSION: FI >/= 1.72 at the time of diagnosis may be an independent predictive marker for ESRD in AAV patients. CI - (c) 2020 John Wiley & Sons Ltd.
