摘要:

摘  要  青年男性患者,临床表现为急进性肾炎综合征伴大量蛋白尿、低蛋白血症,血清抗GBM抗体阳性,肾活检光镜表现为新月体肾炎合并肾小球膜性病变,免疫病理IgG呈线状及颗粒状沉积于血管袢,电镜下肾小球基膜上皮侧电子致密物沉积,最终诊断为抗GBM肾炎合并肾小球膜性病变。

Abstract:

ABSTRACT A 29-year-old male presented with rapidly prograssive glomerulonephritis with macroscopic hematuria and nephrotic proteinuria. Anti-GBM (glomerular basement membrane) antibodies were 139.37RU/ml. Renal histological examination showed membranous nephropathy with 56% cellular crescentic formation. By direct immunofluorescence, there was linear and granular staining of IgG along GBM. The glomerular subepithelial immune complex deposits were demonstrated in electron microscopy. The final diagnosis was anti-GBM nephritis associated with membranous nephropathy.
