Management of antineutrophil cytoplasmic antibody-associated vasculitis: a review of recent guidelines

Abstract

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is an autoimmune rheumatic disease consisting of three discrete diagnoses of microscopic polyangiitis, granulomatosis with polyangiitis, and eosinophilic granulomatosis with polyangiitis. Among diseases treated in a rheumatology department, AAV has poor clinical outcomes, with high rates of mortality and progression to end-stage renal disease and frequent disease relapse. Due to the frequent negative patient outcomes, optimal therapeutic strategies are essential in the management of AAV. In the present review, four guidelines for management of AAV are summarized: British Society for Rheumatology (BSR) and British Health Professionals in Rheumatology (BHPR) guideline for the management of adults with AAV; European League Against Rheumatism (EULAR)/European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) recommendation for the management of AAV; 2021 American College of Rheumatology (ACR)/Vasculitis Foundation Guideline for the Management of AAV; Kidney Disease: Improving Global Outcome (KDIGO) 2021 Clinical Practice Guideline for the Management of Glomerular Diseases, which will aid in clinicians' medical decisions. Finally, the summary of the 2022 Update of the EULAR Recommendations on the Management of AAV, presented in the EULAR Congress 2022 is also introduced.
