[Recommendations on the diagnosis and treatment of anti-neutrophil cytoplasmic antibody associated vasculitis in China].

Anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis (AAV) is a group of systemic small vasculitis characterized by ANCA positive in serum. Three diseases are included in this group of diseases: granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA). In China, standardized diagnosis and treatment of AAV is still lacking. Based on the evidence and guidelines from China and abroad, the Chinese Rheumatology Association formulated the standardization of diagnosis and treatment of ANCA associated vasculitis. The purpose is to standardize the diagnosis of AAV and disease activity assessment, and recommend the treatment strategies.抗中性粒细胞胞质抗体（ANCA）相关血管炎（AAV）是一组以血清中能检测到ANCA为最突出特点的系统性小血管炎。经典AAV包括肉芽肿性多血管炎、显微镜下多血管炎和嗜酸性肉芽肿性多血管炎。我国AAV的规范化诊断与治疗依然欠缺，中华医学会风湿病学分会在借鉴国内外诊治经验和指南的基础上，制定了本规范，旨在规范AAV的诊断与疾病活动度评估，对患者的治疗策略予以建议。.
