Synopsis

Antineutrophil cytoplasmic antibody (ANCA)-associated disease resulting in necrotizing inflammation of small and medium-sized arteries without granuloma formation. Associated with elevated p-ANCA titers and a positive myeloperoxidase (MPO) antibody. Most common sites of involvement are the kidneys (necrotizing crescentic glomerulonephritis) and lungs (which may present with hemoptysis). Severe pulmonary or renal symptoms are considered a medical emergency, and immediate treatment is required.
