肾淀粉样变性患者321例临床与病理分析肾淀粉样变性(renal amyloidosis)是指由于淀粉样物质在肾脏沉积引起的一种疾病。
该疾病通常由于慢性感染、免疫失调、恶性肿瘤等引起的长期慢性炎症反应所致。
肾淀粉样变性是一种常见的肾脏疾病,临床表现多样,严重者可导致肾功能衰竭。
为了进一步了解肾淀粉样变性的临床特点和病理改变,本研究收集了321例肾淀粉样变性患者的临床和病理资料,并进行分析。
研究结果显示,这321例肾淀粉样变性患者中,男性占56.4%,女性占43.6%。
年龄分布范围在20岁至80岁之间,平均年龄为54.6岁。
临床症状主要包括蛋白尿、血尿、水肿和高血压等,其中以蛋白尿最为常见,占68.5%。
超声检查显示,肾脏大小正常或轻度缩小,肾实质回声增强,肾盂和输尿管无明显异常。
肾穿刺活检结果显示,所有患者的肾小球均有淀粉样物质沉积,形成典型的苏木红染色阳性的淀粉样小球。
病理学分型中,免疫病理类型最常见,占53.3%,其次是遗传因素和感染等其他因素所致的肾淀粉样变性,分别占28.7%和17.9%。
病理学分级中,轻、中、重度分别占35.8%、46.4%和17.8%。
进一步分析发现,肾功能的损害程度与肾淀粉样变性的严重程度相关,重度淀粉样小球沉积常导致肾功能衰竭。
另外,免疫病理类型的肾淀粉样变性患者肾功能损害更为明显,并且病程进展较快。
综上所述,肾淀粉样变性是一种常见的肾脏疾病,其临床表现多样,但以蛋白尿为主。
病理学显示淀粉样小球沉积,其中免疫病理类型最为常见。
肾淀粉样变性的严重程度与肾功能损害相关,重度淀粉样小球沉积可导致肾功能衰竭。
免疫病理类型的肾淀粉样变性进展快且肾功能受损较为严重。

Methods A retrospective analysis was conducted in 31 cases of amyloidosis nephropathy. The clinical data and pathologic features of kidney biopsy were analyzed. Re-sults 31 cases of amyloid degeneration accounted for 1. 19% (31/2 603) in all patients of kidney biopsy in the same period. 15 pa-tients were female, and 16 males. Patients’ age ranged from 36 to 77 years old, with mean age of (61. 28 ± 10. 95) years. Clinical staging showed that simple proteinuria were 4 cases (12. 90%), nephrotic syndrome, 21 cases (67. 74%), and renal failure, 6 cases (19. 35%). Under microscope, amyloid deposits were observed in the glomerular mesangial area, capillary basement membrane and small arteries, and those also deposited between renal interstitial and tubular basement membrane in severe cases. Potassium permanga-nate oxidation Congo red staining showed that AL type were 27 cases and AA 4 cases. Immunofluorescence study in some cases showed some degree of weak immunoglobulin and complement deposition, but some cases were negative. Immunohistochemical staining showed different expression of immunoglobulin light chain κ and λ light chains. Under ele ctron microscope, amyloid fibrils were noted in the mesangial area and capillary walls. Conclusion Amyloidosis nephropathy occurs in middle-aged patients with kidney disease, some-times lack of specific clinical manifestations.Renal biopsy is the only approach to confirm the diagnosis. For suspicious patients, renal biopsy should be done as early as possible.%目的:探讨淀粉样变性肾病( amyloid nephropathy, ANP)的临床病理学特征。

方法回顾性分析复旦大学基础医学院病理学系2007年1月至2016年7月肾活检病例中确诊的56例肾淀粉样变性,经免疫染色检测肾组织中免疫球蛋白轻链κ、λ及淀粉样蛋白A(amyloid A,AA)的表达,并分析病理形态学特点及临床表现。
结果56例肾淀粉样变性的发病年龄为(58.6±9.3)岁,高峰年龄段为50~69岁。
42例(75.0%)临床表现为肾病综合征,10例(17.9%)伴2个或以上多器官淀粉样物质沉积。
刚果红染色、偏振光显微镜及电镜检查显示淀粉样物广泛沉积于肾小球、肾小管基膜、间质及血管壁,肾小球重度沉积者24h尿蛋白定量显著高于轻度沉积者。
43例(76.8%)为AL型(36例ALλ型、7例ALκ型),3例(5.4%)为AA型,其余10例(17.9%)免疫染色均为阴性。
46例确定分型的病例中,免疫染色显示多种免疫球蛋白及补体轻度沉积于各型尤其ALλ型,电镜下多未发现电子致密物沉积,提示为非特异性沉积。
电镜检查显著提高早期病变的检出率。
结论ALλ型是本组肾淀粉样变性最常见的病理类型;电镜检查可显著提高其早期病变的确诊率;应常规应用免疫染色确定前体蛋白类型,必要时应进行质谱分析。
