在2013年8月的在线出版的《关节炎与风湿病》(ARTHRITIS & RHEUMATISM)杂志上,发表了马里兰州约翰斯·霍普金斯大学医学院的Michelle A. Petri等人的一项临床III期研究结果。研究旨在分析562位在belimumab临床III期研究中接受标准治疗的中至重度系统性红斑狼疮(SLE)患者复发的预测因素,并评价标准治疗阻止疾病复发的力度。【原文下载】 研究对象

在2013年8月的在线出版的《关节炎与风湿病》(ARTHRITIS & RHEUMATISM)杂志上,发表了马里兰州约翰斯·霍普金斯大学医学院的Michelle A. Petri等人的一项临床III期研究结果。研究旨在分析562位在belimumab临床III期研究中接受标准治疗的中至重度系统性红斑狼疮(SLE)患者复发的预测因素,并评价标准治疗阻止疾病复发的力度。【原文下载

研究对象是治疗后24周和52周病情复发和未复发的SLE患者,研究者事后分析了上述受试者基线时人口统计学、疾病活动度和生物学标记。严重复发定义为修订的SLE复发指数(SFI)和任何新英伦三岛狼疮性评估组(BILAG)A类评分增加。中度至重度复发定义为1项新发的BILAG A类评分或者2项新发的BILAG B类评分增加。基线特征相关绝对差异≥10%,或复发率增加≥50%被认为是SLE复发的预测因素。

52周后,依据SFI、新的BILAG A类评分和1项新发BILAG A类评分或2项新发BILAG B类评分,SLE的复发率分别是23.7%、23.1%和32.0%。依据上述三种复发判定,单因素分析24周和52周复发的相关因素是系统性红斑狼疮激素安全国家标准版SLE疾病活动度指标(SELENA -SLEDAI)积分≥12、抗双链DNA(anti-dsDNA)阳性、尿蛋白(>0.5mg/24h)、BILAG肾损、血管炎和血液系统异常、C-反应蛋白(CRP)水平升高,、及B淋巴细胞刺激因子(BlyS)水平>2 ng/ml。多因素分析52周复发的相关素是SELENA-SLEDAI和/或BILAG肾和anti-dsDNA >200 IU/ml (3种SLE复发定义均符合)、SELENA-SLEDAI和/或BILAG神经系统受累和血管炎(2种复发定义: 任何BILAG A类积分新增加,和1项新发BILAG A累积分或2项新发BILAG B类积分)、BlyS水平≥2 ng/ml(2种复发定义:SFI和1项新发BILAG A累积分或2 项新发BILAG B类积分和C3水平低(1种复发定义:SFI)。基线药物治疗不能显著增加或减少中至重度SLE患者的复发风险。

合并有肾损、神经系统受累或血管炎,anti-dsDNA或者BlyS水平升高或C3水平低的患者,即使接受标准SLE治疗,一年后临床意义的SLE复发的风险仍高。研究结果也不能预测羟氯喹的疗效。

研究背景:

SLE的临床过程多种多样,病情复发(轻度、中度或重度)很常见,每年有65-70%的SLE患者病情复发。因此,早期确定中至重度SLE复发的高风险人群,能提高患者的临床疗效。

一项霍普金斯狼疮队列研究发现SLE复发时常出现抗双链DNA(anti-dsDNA)水平降低。同一人群的一项前瞻性研究揭示,基线时非裔美国人和低C4是一年后SLE复发的独立预测因素。另一项研究揭示,基线血沉、贫血、淋巴细胞减少和抗核抗体(ANA)的滴度能预测一年后SLE复发(SLE活动度积分[SLEDAI]增加>3)。

一项Belimumab(人源性重组IgG1λ单克隆抗体,能特异性抑制可溶性B淋巴细胞刺激因子[BLyS]的生物学活性)的2阶段Ⅲ研究(BLISS,n=562)事后分析发现,联合分析基线人口统计学、SLE疾病活动度和实验室指标,能对治疗24周和52周后,随机分组接受标准化治疗的SLE中至重度复发情况进行预测。本研究采用单因素和多因素分析对中至重度SLE复发的不同定义进行研究。研究者还在这三种不同中至重度SLE复发定义的背景下,评价了SLE标准治疗对预防中至重度SLE复发的作用。
