Ann Rheum Dis:强直性脊柱炎病情越重脊柱影像学进展越明显

2014-08-06 佚名 丁香园

近年来,强直性脊柱炎(AS)患者的炎症程度与其脊柱新骨形成之间的相关性被广泛讨论。肿瘤坏死抑制剂(TNFi)治疗对控制患者的病情活动度有效,然而却无法抑制影像学破坏的进展。为分析 AS 患者的病情活动度与影像学病情进展之间的长期相关性,来自荷兰阿姆斯特丹大学临床风湿免疫专业的 Sofia Ramiro 博士等人对 AS 国际研究项目(OASIS)的研究结果进行纵向队列分析。

近年来,强直性脊柱炎(AS)患者的炎症程度与其脊柱新骨形成之间的相关性被广泛讨论。肿瘤坏死抑制剂(TNFi)治疗对控制患者的病情活动度有效,然而却无法抑制影像学破坏的进展。为分析 AS 患者的病情活动度与影像学病情进展之间的长期相关性,来自荷兰阿姆斯特丹大学临床风湿免疫专业的 Sofia Ramiro 博士等人对 AS 国际研究项目(OASIS)的研究结果进行纵向队列分析。研究结果在线发表于 2014 年 5 月的《风湿病学年鉴》(Ann Rheum Dis)杂志上。研究发现,AS 患者的病情越重,其脊柱影像学进展越明显。

所有研究对象的随访均超过 12 年,每 2 年接受一次临床和影像学病情评估。两名医师根据改良的 stoke 强直性脊柱炎脊柱评分法(mSASSS)对每名患者的 X 线检查结果独立评分。对患者病情活动度的评估方法包括:bath AS 病情活动指数(BASDAI)、C 反应蛋白(CRP)相关的 AS 病情活动指数(ASDAS)、CRP、红细胞沉降率(ESR)、患者对病情的整体评估以及脊柱疼痛的情况。采用 2 年延迟的纵向自回归模型分析疾病活动度与放射学损害之间的关系。

最终研究纳入了 184 例患者,其中 70% 患者为男性,83% 患者 HLA-B27 阳性。患者的平均年龄为 43±12 岁,平均病程为 20±12 年。患者的病情活动度与影像学纵向进展之间存在相关性。而患者是否接受药物治疗或是否存在关节外症状等因素均不影响这种相关性。相较于 BASDAI、CRP、BASDAI 联合 CRP 模型,以 ASDAS 为模型所评估的病情活动度与研究数据的契合度更高。ASDAS 每增加 1 个单位,患者每 2 年的 mSASSS 增加 0.72 分。高病情活动度患者(如 ASDAS>3.5)相较于低病情活动度患者(如 ASDAS<1.3),其每 2 年的 mSASSS 将多进展 2.31 分。男性患者、病程<18 年的患者,其 ASDAS 对 mSASSS 的影响更明显。

该研究首次明确了 AS 患者的病情活动度对脊柱影像学长期进展有影响。这种影响在男性患者及病程早期的患者中更加明显。

脊柱僵硬性疾病包括强制性脊柱炎(AS)和弥漫性特发性骨肥厚(DISH),共同的特征为进行性脊柱的僵硬。强直性脊柱炎为HLA B-27基因相关的炎症性疾病,由于骶髂关节、椎间盘及小关节突的慢性炎症而致脊柱强直,发病率为0.1%-1.4%,发生骨折及神经损害风险很高。临床医生对弥漫性特发性骨肥厚认识不足,其病因不明,主要特点为韧带和附丽点的骨化,以脊柱明显。与50岁以上、肥胖和II型糖尿病有关。由于强

强直性脊柱炎合并髋关节受损的诊疗策略

强直性脊柱炎(AnkylosingSpondylitis,AS)是一种慢性炎症性疾病,主要侵犯骶髂关节、脊柱骨突、脊柱旁软组织及外周关节,引起炎性疼痛、晨僵、活动受限等症状,严重者可出现关节强直。同时可伴发关节外表现,包括眼葡萄膜炎、肠道炎症、指/趾炎、皮疹等,通常为单独出现或重叠存在,其中以眼和肠道的病变最为常见。根据累及部位和临床表现的不同,可将AS分为以脊柱关节受累为主的中轴型和以外周关节受

ACR:HAQ-S可用于AS患者外周关节受累的评价

强直性脊柱炎(AS)患者的功能受限可能是由于外周或者中轴关节受累。针对这一情况,来自美国国立卫生研究院,国立关节炎及肌肉骨骼及皮肤疾病的SIDDHARTH BETHI等人进行了一项研究,研究目的是明确Bath强直性脊柱炎功能指数(BASFI,一项基于中轴的评级方法)是否能检测出周围关节受累相关的功能受限;及修订的脊柱关节炎健康评估调查问卷(HAQ-S,一种基于周围关节的评价方法)是否能检测出中轴关
