目的　了解抗肾小球基底膜抗体（ Ａｎｔｉ Ｇ Ｂ Ｍ） 伴抗中性粒细胞胞浆抗体（ Ａ Ｎ Ｃ Ａ） 阳性患者的临床病理特点。方法　对我科近４ 年来６８ 例 Ａｎｔｉ Ｇ Ｂ Ｍ 和（ 或） Ａ Ｎ Ｃ Ａ 阳性患者进行 Ａｎｔｉ Ｇ Ｂ Ｍ 及 Ａ Ｎ Ｃ Ａ 检测，对其中４ 例两者均阳性患者进行临床病理分析。结果　６８ 例患者中４ 例两者均阳性，占全部 Ａｎｔｉ Ｇ Ｂ Ｍ 阳性患者的２４ ％ ，占全部 Ａ Ｎ Ｃ Ａ 阳性患者的７ ％ 。该４ 例患者 Ａｎｔｉ Ｇ Ｂ Ｍ 的百分结合率较单纯 Ａｎｔｉ Ｇ Ｂ Ｍ 阳性患者低。４ 例中３ 例髓过氧化物酶 Ａ Ｎ Ｃ Ａ（ Ｍ Ｐ Ｏ Ａ Ｎ Ｃ Ａ） 阳性，１ 例蛋白酶３ Ａ Ｎ Ｃ Ａ（ Ｐ Ｒ３ Ａ Ｎ Ｃ Ａ） 阳性，全身系统表现较多，与单纯性 Ａ Ｎ Ｃ Ａ 阳性患者相似。所检病例肾脏病理多为新月体肾炎，免疫荧光检查多为 Ｉｇ Ｇ、 Ｃ３ 呈细颗粒样分布于 Ｇ Ｂ Ｍ。虽经积极治疗，多数患者预后较差，类似单纯 Ａｎｔｉ Ｇ Ｂ Ｍ 肾炎。结论　 Ａｎｔｉ Ｇ Ｂ Ｍ 伴 Ａ Ｎ Ｃ Ａ 阳性患者全身表现类似单纯 Ａ Ｎ Ｃ Ａ 相关小血管炎患者，但治疗效果及预后相对较差又类似于 Ａｎｔｉ Ｇ Ｂ Ｍ 肾炎患者 Objective To investigate the clinicopathological features of Anti-G B M and anti-neutrophil cytoplasmic antibody (A N C A) -positive patients. Methods Anti-G B M and A N C A were detected in 68 cases of AntiG B M and / or A N C A positive patients in the past 4 years in our department. Clinicopathological analysis of 4 positive patients . Results Of the 68 patients, 4 were both positive, accounting for 24% of all Anti-G B M-positive patients and 7% of all A N C A-positive patients. The percentages of Anti-G B M in the 4 patients were lower than those in Anti-G B M-positive patients. In 4 cases, 3 cases of myeloperoxidase  A N C A (M P O  A N C A) positive, 1 case of protease 3  A N C A (P R3  A N C A) positive, systemic performance More, similar to simple A N C A positive patients. Most cases of renal pathology were crescentic nephritis, immunofluorescence mostly Ig G, C3 were finely distributed in the G B M. Despite aggressive treatment, the majority of patients with poor prognosis, similar to pure Anti GBM nephritis. Conclusion AntiG B M with A N C A positive patients with systemic manifestations similar to simple NA C A related vasculitis patients, but the treatment effect and prognosis is relatively poor and similar anti-G B M nephritis patients
