摘要:

目的:探讨抗肾小球基膜(GBM) 病合并 IgA 肾病(IgAN) 或膜性肾病(MN) 患者的的临床病理特征及预后特点。
方法:选取2004年1月~2015年12月于南京总医院国家肾脏疾病临床医学研究中心经肾活检确定为抗 GBM 病合并 IgAN 患者(合并 IgAN 组)10例,抗 GBM 病合并 MN 患者(合并 MN 组)5例,与60例单纯抗 GBM 病患者(单纯抗 GBM病组)比较,分析三组患者在临床表现、肾活检病理特征及预后的差异。
结果:与单纯抗GBM病组相比,合并IgAN组、合并MN组患者出现无尿者较少,蛋白尿和镜下血尿较多,抗GBM抗体滴度较低,但均无统计学差异。单纯抗GBM病组患者肾损伤程度较重,临床表现为急进性肾炎综合征(RPGN)的比例明显增高(P=0004),高血压比例高(P=0002),血肌酐峰值最高(P<0001),且贫血程度重(P<0001)。单纯抗GBM病组患者总新月体比例高(P=0008)且包囊壁断裂比例亦高(P=0005)。单纯抗 GBM组患者需连续肾脏替代治疗比例最高(P=0008)。单纯抗GBM病组患者1年内进展至终末期肾病比例最高(P<0001)。
结论:合并IgAN或MN的抗GBM病在临床表现、实验室检查、病理指标及预后均不同于单纯抗GBM病。

Abstract:

Objective:To investigated the differences in clinical characteristics,pathological features and prognosis of antiglomerular basement membrane (GBM) disease combined with IgA nephropathy or membranous nephropathy.
Methodology:From January 2004 to December 2015, seventy five patients with antiGBM disease were enrolled into this retrospective study. According to the pathological diagnosis, the patients were divided into three group, including 10 cases of antiGBM disease with IgA nephropathy (with IgAN group), 5 cases of antiGBM disease with membranous nephropathy (with MN group) and 60 cases of simple antiGBM disease (simple antiGBM disease group). The clinical, laboratory and pathological indices were compared among the three groups.
Results:In patients of antiGBM disease with IgAN group and with MN group, they had lower percents of anuria, while more urine protein and microscope hematuria, and a lower level of antiGBM antibodies, but not statistical significance. Furthermore, the patients in simple antiGBM disease group were more serious in renal dysfunctions, which represented as highest percents of rapidly progressive glomerulonephritis (RPGN) (P=0004), highest levels of hypertension (P=0002), serum creatinine (SCr,P<0001) and a more serious degree of anemia (P<0001). In pathology, the patients in simple antiGBM disease group were observed to have the highest percentage of crescents in glomeruli (P=0008) and Bowmans wall fracture (P=0005). In the course of treatment, the patients in simple antiGBM disease group had the highest proportion of continuous renal replacement therapy(P=0008). During the followup, the patients in simple antiGBM disease group had the highest percentage of end stage renal disease (ESRD) in one years (P<0001).
Conclusion:
AntiGBM disease with IgA nephropathy or membranous nephropathy is different from simple antiGBM disease in clinical manifestations, laboratory indices, pathology and prognosis.
