Objective To describe the prevalence of fibromyalgia (FM) in an axial spondyloarthritis (axSpA) population and to confirm that concomitant FM had a negative impact on tumour necrosis factor blockers’ (TNFb) response. Design Prospective observational study with two visits 3 months apart. Patients Adult patients with AxSpa initiating a TNFb. Study groups FM was defined by the Fibromyalgia Rapid Screening Tool (FiRST) at baseline and also by a sustained positive FiRST (both visits) and by a fulfilment of the 1990 American College of Rheumatology criteria for FM. Statistical analysis Prevalence of FM; evaluation of the impact of a concomitant FM on TNFb response (Bath Ankylosing Spondylitis Disease Activity Index (BASDAI 50) as primary endpoint), adjusted by factors known to have an impact on TNFb response. Results Among the 508 patients included in the main analysis, 192 (37.8%) were screened at baseline as FM. Percentage of success after 12 weeks of treatment was lower in the FM group for most of the effectiveness endpoints (eg, BASDAI 50: 45.3% vs 54.1% in the FM/not FM groups according to the FiRST), except for the C reactive protein change endpoints which were not different across groups. Conclusion This study confirms that FM coexists in patients with axSpA and that its presence seems to have a negative impact on TNFb response, which seems more related to the self-reported instruments used in its evaluation, rather than a different treatment effect of the molecule in this subgroup of patients.

评估伴随的纤维肌痛对 TNF α 受体阻滞剂治疗中轴性脊柱关节炎有效性的影响:一项前瞻性、多中心研究的结果

目的描述中轴性脊柱关节炎 (axSpA) 人群中纤维肌痛 (FM) 的患病率,并确认伴随的 FM 对肿瘤坏死因子阻滞剂 (TNFb) 的反应有负面影响。设计前瞻性观察研究,两次访问间隔 3 个月。患者 启动 TNFb 的 AxSpa 成年患者。研究组 FM 由基线时的纤维肌痛快速筛查工具 (FiRST) 以及持续阳性的 FiRST(两次访问)和 1990 年美国风湿病学会 FM 标准定义。统计分析 FM 流行率;评估伴随的 FM 对 TNFb 反应的影响(Bath 强直性脊柱炎疾病活动指数(BASDAI 50)作为主要终点),根据已知对 TNFb 反应有影响的因素进行调整。结果 在主要分析中包括的 508 名患者中,192 名 (37.8%) 在基线时被筛选为 FM。对于大多数有效性终点,FM 组治疗 12 周后的成功百分比较低(例如,根据 FiRST,BASDAI 50:45.3% 与 FM/非 FM 组中的 54.1%),除了 C 反应蛋白更改在组间没有差异的端点。结论 本研究证实 FM 与 axSpA 患者共存,并且它的存在似乎对 TNFb 反应有负面影响,这似乎与其评估中使用的自我报告工具更相关,而不是与该分子在治疗中的不同治疗效果有关。这一亚组患者。对于大多数有效性终点,FM 组治疗 12 周后的成功百分比较低(例如,根据 FiRST,BASDAI 50:45.3% 对 FM/非 FM 组中的 54.1%),除了 C 反应蛋白更改在组间没有差异的端点。结论 本研究证实 FM 与 axSpA 患者共存,并且它的存在似乎对 TNFb 反应有负面影响,这似乎与其评估中使用的自我报告工具更相关,而不是与该分子在治疗中的不同治疗效果有关。这一亚组患者。对于大多数有效性终点,FM 组治疗 12 周后的成功百分比较低(例如,根据 FiRST,BASDAI 50:45.3% 对 FM/非 FM 组中的 54.1%),除了 C 反应蛋白更改在组间没有差异的端点。结论 本研究证实 FM 与 axSpA 患者共存,并且它的存在似乎对 TNFb 反应有负面影响,这似乎与其评估中使用的自我报告工具更相关,而不是与该分子在治疗中的不同治疗效果有关。这一亚组患者。
