ACR2010_前瞻性起始队列研究比较uSpA、AS和PsA患者的临床表现与治疗反应

USpA是介于ASPsA之间的表型,仅有部分患者表现为放射学前期中轴型SpA。虽然表现不典型、病程较短,但大部分USpA患者病情活动度高。本研究发现TNF抑制剂疗效明显。放射学前期AS的随机对照研究数据越来越多,除了ASPsA之外,我们应系统评估这种新疗法在中轴型和周围型USpA中的作用。

Background: Ankylosing spondylitis (AS) and psoriatic arthritis (PsA) are the best described and studied subtypes of spondyloarthritis (SpA). A significant proportion of SpA patients, however, does not fulfil the classification criteria for AS and PsA and are at risk to be diagnosed and treated late. The aim of this study was to assess whether patients with undifferentiated SpA (USpA) are different from AS and PsA in terms of patient characteristics, disease activity and response to treatment.
Methods: 175 patients presenting on a dedicated SpA outpatient clinic fulfilling the European Spondyloarthropathy Study Group (ESSG) criteria were recruited in a prospective inception cohort. Global assessment of disease activity visual analogue scale (VAS) patient and physician, Bath Ankylosing Spondylitis Disease Activity (BASDAI), 68 swollen and tender joint count, Schober, ESR and CRP were measured every 3 months. Parametric tests were used for normally distributed data and non-parametric tests for non-normally distributed data.
Results: The baseline demographic and clinical data are shown in Table 1.

前瞻性起始队列研究比较未分化脊柱关节炎、强直性脊柱炎和银屑病关节炎患者的临床表现与治疗反应

                    

Paramarta JE, et al. ACR 2010. Present No: 2272.

      

背景: 强直性脊柱炎(AS)与银屑病关节炎(PsA)是研究最多的脊柱关节炎(SpA)亚型。相当一部分SpA患者并不符合ASPsA的分类标准,有可能延误诊断及治疗。本研究旨在探讨未分化SpAUSpA)与ASPsA在患者特征、疾病活动度及治疗反应是否存在差别。

方法: 175例就诊于SpA专科门诊、符合ESSG标准的患者被纳入前瞻性起始队列。每3个月进行疾病活动度评估,包括患者和医生VASBath强直性脊柱炎疾病活动度评分(BASDAI)、68个肿胀和压痛关节计数、SchoberESRCRP。正态分布资料采用参数检验,非正态分布资料采用非参数检验。

结果: 1列出了基线期人口学资料和临床资料。

USpA相比,* 趋势(0.05<p<0.1),** 显著差异(p<0.05

The cohort included 40 USpA, 74 AS and 45 PsA patients. The age of onset (median 32 years; range 11-62), disease duration (1.3 years; 0-36), and proportion of male patients (42.5%) were lower in USpA than in AS and PsA. USpA patients had more axial and less peripheral disease than PsA, but less axial and more peripheral disease than AS. The presence of HLA-B27 (43%) and either high or low grade sacroiliitis (47.5%) were less frequent in USpA than in AS. Only 25% of the USpA patients fulfilled the ASAS criteria for pre-radiological AS, although it should be noted that MRI was not systematically performed. Half of the USpA group had a positive family history. Despite the atypical presentation, the baseline disease activity (VAS patient/physician and BASDAI) was higher in USpA than in the other groups. Upon initiation of TNF blockade in patients with high disease activity, we observed a significant and sustained decrease of the disease activity in USpA, which was similar in amplitude to the response in AS and PsA (Figure 1).

共纳入40USpA74AS45PsA患者。USpA患者的起病年龄(中位数年龄为32岁,范围: 1162岁)、病程(1.3年,036年)和男性患者比例(42.5%)均低于ASPsA患者。与PsA患者相比,USpA患者中轴病变更多,周围病变更少;与AS相比,USpA患者中轴病变更少,周围病变更多,而且HLA-B27阳性率(43%)、轻度或重度骶髂关节炎发生率(47.5%)更低。仅有25% USpA患者符合ASAS放射学前期AS的标准,但并未系统进行MRI检查。半数USpA患者有阳性家族史。尽管症状不典型,但USpA的基线期疾病活动度(患者/医生VASBASDAI)高于其他两组。疾病活动度高且使用了TNF抑制剂的USpA患者疾病活动度显著并持续下降,这与ASPsA的反应相似(表1)。

Conclusion: USpA displays an intermediate phenotype between AS and PsA, with only part of the patients representing pre-radiological axial SpA. Despite the atypical presentation and shorter disease duration, a large majority of USpA patients have high disease activity. The apparent efficacy of TNF blockers in this observational study, together with the emerging data of RCT in pre-radiological AS pleas for systematic assessment of novel treatments not only in AS and PsA but also in axial and peripheral USpA.

结论: USpA是介于ASPsA之间的表型,仅有部分患者表现为放射学前期中轴型SpA。虽然表现不典型、病程较短,但大部分USpA患者病情活动度高。本研究发现TNF抑制剂疗效明显,而且放射学前期AS的随机对照研究数据越来越多,除了ASPsA之外,我们应系统评估这种新疗法在中轴型和周围型USpA中的作用。
