Prognostic Value of Hematological Parameters in Anti-Neutrophil Cytoplasmic Antibody-Associated Vasculitis

Objective: Hematological parameters including neutrophil–lymphocyte ratio (NLR), platelet–lymphocyte (PLR), and monocyte–lymphocyte (MLR) have been demonstrated as new predictors of prognosis activity in various diseases. In this study, we aimed to investigate the associations NLR, PLR MLR with disease severity patients anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV). 
 Materials Methods: Medical records 92 AAV were investigated retrospectively. The clinical laboratory data, outcomes recorded. having five factor score (FFS) ≥ 2 categorized severe disease.
 Results: a median age 60 years included. Patients NLR≥4.8 (RR 1.83), PLR≥151.8 2.02) MLR≥0.38 1.85) had higher risk disease. correlation analysis, positively correlated C reactive protein erythrocyte sedimentation rate (ESR). remission. Conclusion: Only high relapse rate. was also development end-stage renal (ESRD). Renal involvement more frequent levels MLR. Conclusions: We showed that at diagnosis AAV. This is first showing ESRD
