IgA肾病的病理表现复杂多样,一直以来没有一个被广为接受的病理分型。IgA肾病牛津病理分型的制定过程非常严谨和科学,自2009年发表至今引起了广泛关注,不同国家对该分型进行了验证,但由于入选病例临床表现不同、随访过程中治疗方法不同、种族的差异,以及多为小样本、少终点事件的回顾性研究,因此导致目前验证研究的结果之间存在很大差异。最新的研究通过对目前已有的12项验证研究进行的荟萃分析,发现系膜细胞增生病变、节段性硬化或粘连病变及肾小管萎缩或间质纤维化病变是影响IgA肾病肾脏预后的独立病理指标,内皮细胞增生病变不是影响肾脏预后的病理指标。IgA肾病病理分型的临床意义和应用价值有待进一步的大样本、多中心、前瞻性研究进行证实。

The pathological presentation of IgA nephropathy (IgAN) is very complex and diverse.No pathological classification has gained wide acceptance as ideal in clinical practice yet. The Oxford classification of IgAN, established by an international consensus working group in 2009, has developed a consensus on specific pathologic features to reliably predict risk of IgAN progression. Validation of the Oxford classification has been carried out in many studies including different ethnic populations.However, these results are debated, which may be partially due to enrolled patients with different clinical presentations, follow-up therapy strategies, as well as the small sample size in most studies with few endpoints observed. A meta-analysis was carried out recently finding that the lesions of mesangial hypercellularity, segmental glomerulosclerosis, and tubular atrophy and interstitial fibrosis, but not endocapillary hypercellularity, of Oxford classification, were strongly associated with kidney outcome of IgAN. The clinical significances of the Oxford classification need to be confirmed by large sample, multicenter, and prospective studies.
