摘要 目的:探究多发性骨髓瘤并淀粉样变性患者IgG、LDH的表达与其病理特征的关系。方法:选取我院2019年2月至2023年1月收治的65例多发性骨髓瘤临床资料,采用骨髓活检联合刚果红染色及偏振光纤维镜检查,确定多发性骨髓瘤伴淀粉样变性的诊断;将多发性骨髓瘤分为淀粉样变性阳性组、阴性组;分析两组血清生物标志物及血清免疫标志物变化特征。结果:65例多发性骨髓瘤患者发现伴发淀粉样变阳性14例,伴发淀粉样变阴性51例。多发性骨髓瘤患者伴发淀粉样变阳性组LDH、LDH1水平高于阴性组(P<0.05);两组ALT、AST、ALP及AFU水平无统计学差异(P>0.05)。多发性骨髓瘤患者伴发淀粉样变阳性组IgG低于阴性组(P<0.05);两组IgA、IgM、κ、λ水平无统计学差异(P>0.05)。结论:多发性骨髓瘤并淀粉样变性患者LDH呈高表达、IgG水平呈低表达,虽不能直接用IgG、LDH指标进行疾病诊断,但是可作为肿瘤发展的参考依据。对于可疑的多发性骨髓瘤伴有淀粉样变患者,应做到临床表现、实验室检查和骨髓组织活检相结合,才能提高MM伴淀粉样变的确诊率。
