风湿病较为严重的并发症之一是肾衰。肾衰更可能发生于SLE。图示肾小球,其中的毛细血管袢中呈明显的粉红色、管腔增厚，以至于毛细血管腔难以看见。即狼疮肾。
One of the feared complications of the rheumatic diseases is renal failure. This is most likely to occur with SLE. Here is a glomerulus in which the capillary loops are markedly pink and thickened such that capillary lumens are hard to see. This is lupus nephritis.
