Methods. One hundred and forty patients with ANCA were detected for anti PR3 a nd anti MPO by ELISA. The clinical features at presentation, histopathological characteristics and outcome of all patients who were tested positive for anti P R3 or anti MPO were analysed.Results. In anti PR3 group (n=21), 16 cases (76.2%) had systemic vasculitis , in which Wegener’s granulomatosis prevailed (13 cases, 61.9%). In anti MPO g roup (n=31), 19 cases (61.3%) were diagnosed as systemic vasculitis and 12 case s (38.7%) as microscopic angiitis. For vasculitic patients with anti PR3 and a nti MPO, the disease duration at diagnosis was 9.6±2.0m and 4.4±0.9m respecti vely, P< 0.05;vasculitis activity index (BVAS) and mean number of affected organ were 22.5±2.1, 5.0±0.4 and 25.1±1.7, 4.8±0.4 respectively, P >0.05;upper r espiratory tract, eye and joint involvements were 11(68.8%), 7(43.8%), 11(68.8 %) and 7(36.8%), 2(10.5%), 5(26.3%) respectively, P< 0.05.Although there was no statistical difference in renal involvement between these two groups, patien ts with serum creatine >500 μmol/L were more commonly seen in anti MPO group t han in anti PR3 group, which were 8(42.1%) and 2(12.5%) respectively, P< 0.05 . Ten relapses were seen in anti PR3 group and only 2 in anti MPO group, but t he acute mortality rate in anti MPO group (5/19, 27.4%) was much higher than t hat in anti PR3 group (1/16, 6.3%). Conclusions. Anti PR3 and anti MPO occurred mainly in systemic vasculitis. A large divergence was seen in the disease spectrum between patients with anti PR 3 and those with anti MPO. In particular, upper respiratory tract, eye and join t involvements, granuloma formation and relapse were more prominent in anti PR3 patients. By contrast, the anti MPO patients had a more acute disease onset, m ore rapid progressive renal involvement and a higher acute mortality rate.展开更多
