title: [The renal involvement of primary vasculitis: clinical and pathological analysis of 5 cases].
abstract: Primary vasculitis, include microscopic polyarteritis (MPA) and Wegener's granulomatosis (WG), is one of the causes of Glomerulonephritis and renal failure. Recently antineutrophil cytoplasmic autoantibodies (ANCA) is considered to be a very important tool for the diagnosis of MPA and WG. The management of ANCA was performed in 42 patients with variant primary glomerulonephritis with crescents formation or sclerotic glomerulonephritis, 5 of them show positive, appeared as a pattern of P-ANCA. Most of the patients were old male, with fever, malaise, weight loss, anemia, muscle and joint pain, some of them have chronic cough, even hemoptysis, opacities in middle-lower fields of both lungs, which didn't response to antibiotics therapy. This is the first report about renal involvement of primary vasculitis from China. Our result suggest that primary vasculitis is not a rare course of renal failure in China.
