We present a case report of a 37-year-old woman with multiple sclerosis (MS) who developed nephrotic-range proteinuria secondary to membrano proliferative glomerulonephritis (MPGN)-like disease with mesangial C3 deposition without evidence of immune-complex deposition in the context of long-term interferon-β (IFN-β) therapy. The complete remission of proteinuria following cessation of IFN-β, strongly suggests causality. To our knowledge, this is the second case report of MPGN associated with IFN-β use. This being the case, the negative immune screen, normal inflammatory markers and the absence of immune complex deposits would imply a different pathway to that previously suggested.
我们报告一例37岁的多发性硬化症(MS)女性患者,在长期使用干扰素-β(IFN-β)治疗期间,继发膜增生性肾小球肾炎(MPGN)样疾病伴系膜C3沉积,出现肾病范围蛋白尿,且无免疫复合物沉积证据。停用IFN-β后蛋白尿完全缓解,强烈提示存在因果关系。据我们所知,这是第二例与使用IFN-β相关的MPGN病例报告。既然如此,免疫筛查阴性、炎症标志物正常以及无免疫复合物沉积意味着其发病途径与之前提出的不同。
