目的:探讨着丝点蛋白B(centromere protein B,CENP-B)抗体阳性的原发性干燥综合征(primary Sj9gren’s syndrome,pSS)患者的临床和免疫学特征。方法:采用横断面研究的研究设计,回顾性纳入2016年1月至2022年8月就诊于北京大学口腔医院并...目的:探讨着丝点蛋白B(centromere protein B,CENP-B)抗体阳性的原发性干燥综合征(primary Sj9gren’s syndrome,pSS)患者的临床和免疫学特征。方法:采用横断面研究的研究设计,回顾性纳入2016年1月至2022年8月就诊于北京大学口腔医院并确诊为pSS的患者,收集分析患者的一般及临床特征、唾液腺造影、唇腺活检病理、血清免疫学及生化检查等资料。将pSS患者分为CENP-B抗体阳性组和阴性组,用SPSS 23.0软件对数据进行描述性分析、单因素及相关性分析,并将CENP-B抗体阳性组分为CENP-B抗体单阳性组及合并其他抗体阳性组进行亚组分析。结果:共纳入288例pSS患者,其中CENP-B抗体阳性组75例(26.0%),阴性组213例(74.0%)。CENP-B抗体阳性组的发病年龄较大,罹患自身免疫性肝病的比例较高,唾液腺肿大的比例较低,SSA/Ro60、Ro52、SSB抗体的阳性率均较低,免疫球蛋白G、类风湿因子的水平较低,免疫球蛋白M的水平较高,总蛋白水平较低,而白蛋白/球蛋白比值、谷丙转氨酶、谷草转氨酶、碱性磷酸酶、γ-谷氨酰转移酶、乳酸脱氢酶的水平较高。亚组分析显示,CENP-B抗体单阳性组的总蛋白、免疫球蛋白A水平低于合并其他抗体阳性组。结论:CENP-B抗体阳性的pSS患者具有独特的临床和免疫学特征,表现为疾病活动性较低,较少发生唾液腺肿大,但易罹患自身免疫性肝病,肝功能生化指标水平偏高,提示CENP-B抗体可能是pSS亚型分类的特异性标志物。展开更多
