研究表明,利妥昔单抗治疗风湿性疾病高效、安全,特别是为传统治疗效果差的患者提供了新的治疗手段。2016年3月发表在《Joint Bone Spine》的一项在瑞士开展的研究考察治疗前B细胞计数或利妥昔单抗再治疗是否可以预测感染的发生。

难治性风湿性关节炎(RA)和其他严重自身免疫疾病(AID)患者中,利妥昔单抗(RTX)的使用越来越多。在实践中,由于存在感染风险,很多医生不愿为低B细胞计数的患者使用RTX。因此,本研究旨在考察治疗前B细胞减少是否可以预测使用RTX时发生感染。

在一家三级医院对161名接受RTX治疗RA和其他AID的患者进行观察性、单中心研究。用流式细胞仪评估CD19+B细胞计数。使用多变量统计分析对不同潜在预测因素进行分析校正。

RA患者中严重感染率为5.9/100患者-年,非RA AID患者中为24.9(P<0.001)。RTX输注时低B细胞计数与后来严重(HR=0.55,P=0.60)或整体感染(HR=0.85,P=0.58)无关。严重感染显著的治疗前预测因素是除RA之外的其他AID(HR=4.68,P<0.001)、免疫球蛋白(Ig)**平<7 g/L(HR=2.36,P=0.01)、年龄(HR=1.03,P=0.01)和糖尿病(HR=3.61,P=0.01)。

RTX输注前低B细胞计数不能预测接受RTX治疗RA和其他AID的这一人群中的后来的感染,因此不支持治疗前评估B细胞计数。然而,治疗前Ig**平较低、年龄较大、糖尿病和除RA之外的AID,可增加发生严重感染的风险。
