【摘要】 目的了解M蛋白的分型及临床意义,提高认识和诊断水平。方法通过对1998年1月至2005年12月上海交通大学医学院附属新华医院血液科诊治及少量外院送检标本M蛋白阳性者共639例结合临床对年龄、性别和疾病分布,以及多发性骨髓瘤(MM)与意义未明或继发性单克隆丙种球蛋白(MGUS)的特点进行分析。结果639例M蛋白血症中IgG型409例(64.0%)、IgA型80例(12.5%)、IgM型79例(12.4%)、IgD型4例(0.6%)、轻链型27例(4.2%,其中κ9例、λ18例)、双克隆型27例(4.2%)、单克隆型13例(2.0%)。该组患者病种分布,MM115例(18.0%)、华氏巨球蛋白血症(WM)13例(2.0%)、肾原发性淀粉样变性(AL)1例、非霍奇金淋巴瘤(NHL)19例(3.0%)、慢性淋巴细胞白血病(CLL)5例(0.8%)、MGUS473例(74.0%)、寡克隆13例(2.0%)。结论M蛋白血症是一种亚临床现象,主要见于MM及淋巴细胞增殖性疾病,意义未明或继发者检出率有增加趋势。更多还原

【Abstract】 Objective To understand the typing and clinical significance of M-protein,to raise the understanding and diagnostic level through analysis of 639 patients with M-protein.Methods To analysis age,sex and disease of M-protein positive patients,charateristic and content difference of multiple myeloma(MM)and monoclonal gammopathy of undeterminal significance(MGUS).Results In 639 patients with M-proteinemia,there were 409 patients with IgG-type(64%),80 IgA-type(12.5%),79 IgM-type(12.4%),4 IgD-type(0.6%),9 κ light chain(1.4%),18 λ light chain(2.8%),27 double clone(4.2%),oligoclone(2.0%).There were 115 MM(18.0%),13 Waldenstrm’s macroglobulinemia(2.0%),1 primary amyloidosis of kidney,19 non-Hodgkin’s lymphoma(NHL)(3%),5 chronic lymphocytic leukemia(CLL)(0.8%),473 MGUS(74.0%).Conclusion M-proteinemia is a clinical phonomenon,mainly in MM and lymphocytic proliferative disease.There is an improving tendency in MGUS detectable rate.更多还原
