PG - 423-431 LID - S1051-2276(21)00162-X [pii] LID - 10.1053/j.jrn.2021.06.004 [doi] AB - OBJECTIVES: This study investigated whether the nutritional risk index (NRI) score at diagnosis might be useful for anticipating poor prognosis, in particular, all-cause mortality and end-stage renal disease (ESRD) in patients with antineutrophil cytoplasmic antibody-associated vasculitis (AAV). METHODS: The medical records of 242 immunosuppressive drug-naive patients with AAV were retrospectively reviewed. Data at diagnosis and poor prognosis and medications during follow-up were assessed. The NRI score was calculated by 1.519 x serum albumin (g/L) + 41.7 x present (kg)/ideal body weight (kg). RESULTS: The median age at diagnosis of patients with AAV (131 microscopic polyangiitis, 62 granulomatosis with polyangiitis, and 49 eosinophilic granulomatosis with polyangiitis) was 60 years (85 male). During follow-up, twenty-nine patients (12.0%) died after a period of 35.9 months, and 42 patients (17.4%) had ESRD for a period of 30.0 months. Using the receiver operator characteristic curve, the cutoffs of the NRI scores for all-cause mortality and ESRD were calculated as NRI
