摘要
2016年,在荷兰莱顿大学召开了由18名成员参加的国际肾脏病理学工作组会议,会议提出对狼疮性肾炎(LN)病变定义和分型进行修订第一阶段,对LN的部分病变包括系膜细胞增多,细胞、纤维细胞和纤维性新月体等病变定义做了修订。把"毛细血管内增殖"(endocapillary proliferation)修订为"毛细血管内细胞增多"(endocapillary hypercellularity)。取消LN-Ⅳ球性(G)和节段(S)亚型的分类。LN-Ⅲ和Ⅳ中活动性(A)和慢性化(C)名称修订为NIH活动性和慢性化指数评分。活动性指数评分中包含纤维素样坏死。针对目前证据不足及有争议的问题,将在第二阶段利用临床病理研究来探讨,对新修订定义的病变和分型的可重复性及意义进行观察验证。
