摘要:

摘要:老年女性,病程3月,以肉眼血尿起病,尿常规示大量镜下血尿,中等量蛋白,短期内血肌酐升高、一过性高钙血症,中度贫血,一过性高钙血症,骨髓浆细胞占45.5﹪,血游离轻链比例明显异常,免疫固定电泳见λ型IgG单克隆免疫球蛋白。肾活检病理免疫荧光仅见C3弥漫颗粒状沉积于系膜区及血管袢,组织学见肾小球节段系膜内皮增殖伴系膜区、内皮下、基膜内嗜复红物沉积。最后诊断多发性骨髓瘤相关性C3肾小球肾炎。

Abstract:

ABSTRACT A 64-years-old female was characterized by gross hematuria, renal dysfunction, high globulin, anemia, lower serum C3 level, hypercalcemia and hypertension. Bone marrow showed 45.5% of plasma cells and free light chain κ/λ ratio was abnormal. Serum immunofixation showed monoclonal IgG-λ positive. However, renal biopsy showed C3 glomerulonephritis. The final diagnosis was multiple myeloma associated with C3 glomerulonephritis

Key words: multiple myeloma, monoclonal immunogolobulin
