Arthritis Care Res : 病程短、疾病活动度高的RA患者更易从研究中脱落

2013-10-28 佚名 丁香园

观察随访登记的患者已成为了解​​类风湿关节炎(RA)的遗传背景和治疗策略的一个重要工具,在特定药物治疗的长期疗效研究方面也具有价值。患者的流失对分析临床终止可产生深远影响,明确患者退出的特点及相关因素也很重要。针对这一情况,来自马萨诸塞州布里格姆和妇女医院的CHRISTINE K.等研究者进行了一项研究。研究结果发表于2013年7月的《关节炎与风湿病》(ARTHRITIS & RHEUMA

观察随访登记的患者已成为了解​​类风湿关节炎(RA)的遗传背景和治疗策略的一个重要工具,在特定药物治疗的长期疗效研究方面也具有价值。患者的流失对分析临床终止可产生深远影响,明确患者退出的特点及相关因素也很重要。针对这一情况,来自马萨诸塞州布里格姆和妇女医院的CHRISTINE K.等研究者进行了一项研究。研究结果发表于2013年7月的《关节炎与风湿病》(ARTHRITIS & RHEUMATISM)杂志上。研究发现,类风湿关节炎(RA)研究患者的流失的因素是多方面的,包括RA疾病活动、RA药物治疗类型和患者的社会经济地位等,早期还受到性别和年龄的影响。【原文下载

该研究的受试者主要来自于就诊在布里格姆与妇女医院的RA患者,共纳入1144例 RA患者。利用单因素分析对人口统计学和临床心理因素进行评估,以确定终止治疗的患者与完成5年随访的患者之间是否存在差异。通过生存分析中P值<0.1的单变量因素确定与消耗相关联的显著因素。应用二次分析对在第一年即终止治疗的患者进行分析。

1144 RA患者纳入了此项研究。患者平均年龄为56.0±14.0岁,基线平均病程为13.5± 12.3年。有509例患者完成了5年随访,227例仍在积极随访中,408例患者脱落。每6个月周期的流失率是4.31%。在多因素生存分析中,病程短、疾病活动度高(应用C-反应蛋白的三度DAS28评分)、受教育程度低、RA用药以及关节炎自我管理较差均有统计学意义。在二次分析中,发现性别和年龄是导致患者流失的额外因素。男性和年轻患者往往在随访早期就退出了。此外,每个登记表中的人群差异也可能会导致不同形式的流失。

该研究发现,本次研究报道的RA患者脱落率与其他报道的比例基本相似。病程短,疾病活动度高及其他一些社会经济因素与脱落相关。男性和年轻患者更易于在随访的第一年期间发生脱落。每个中心因人种差异而出现了不同的脱落形式,而最终以纵向研究的结果为准。
