Objectives Identification of RA patients at a high risk of joint destruction remains challenging. The C-X-C motif chemokine 13 (CXCL13) has previously been suggested as a marker of disease activity in RA. Here, we investigate the potential of plasma CXCL13 as a marker of long-term radiographic status and progression. Methods CXCL13 was measured in plasma from treatment-naïve RA patients (n = 158) with an 11-year follow-up. At baseline, clinical and biochemical DASs were obtained; among these CRP, ESR, DAS in 28 joints with CRP (DAS28CRP), number of swollen joints (SJC28) and radiographic status, evaluated by total Sharp score (TSS). Age- and gender-matched healthy controls (HCs) were included. Results CXCL13 was significantly increased at baseline and decreased during treatment; however, it was not reduced to the level in HCs. At baseline, CXCL13 was associated with both CRP and ESR, but not with other markers of disease activity. Baseline CXCL13 was correlated with both TSS and radiographic progression (ΔTSS) at 11 years. With an 89% probability, levels of CXCL13 above 85 pg/ml predicted the risk of a TSS of 5 or above, after 11 years of treatment. Compared with CRP, DAS28CRP, SJC28 and ACPA status, CXCL13 was superior in predicting 11-year joint destruction. Conclusion In early RA, one single measurement of plasma CXCL13 at baseline is superior to currently used clinical and serological disease markers in the prediction of long-term radiographic status and progression.

CXCL13 预测早期类风湿性关节炎的长期影像学状态

目标 识别具有关节破坏高风险的 RA 患者仍然具有挑战性。CXC 基序趋化因子 13 (CXCL13) 先前已被建议作为 RA 疾病活动的标志物。在这里,我们研究了血浆 CXCL13 作为长期放射学状态和进展标志物的潜力。方法 CXCL13 是在 11 年随访后未接受治疗的 RA 患者(n = 158)的血浆中测量的。在基线时,获得了临床和生化 DAS;在这些 CRP、ESR、28 个 CRP 关节中的 DAS (DAS28CRP)、肿胀关节数 (SJC28) 和放射学状态中,通过总 Sharp 评分 (TSS) 进行评估。包括年龄和性别匹配的健康对照(HCs)。结果 CXCL13在基线时显着升高,在治疗期间降低;但是,它并没有降低到 HC 中的水平。在基线时,CXCL13 与 CRP 和 ESR 相关,但与其他疾病活动标志物无关。基线 CXCL13 与 11 年时的 TSS 和放射学进展 (ΔTSS) 相关。治疗 11 年后,CXCL13 水平高于 85 pg/ml 的概率为 89%,可预测 TSS 为 5 或更高的风险。与 CRP、DAS28CRP、SJC28 和 ACPA 状态相比,CXCL13 在预测 11 年关节破坏方面具有优势。结论 在早期 RA 中,单次测量基线血浆 CXCL13 在预测长期影像学状态和进展方面优于目前使用的临床和血清学疾病标志物。在治疗 11 年后,CXCL13 水平高于 85 pg/ml 可预测 TSS 为 5 或更高的风险。与 CRP、DAS28CRP、SJC28 和 ACPA 状态相比,CXCL13 在预测 11 年关节破坏方面具有优势。结论 在早期 RA 中,单次测量基线血浆 CXCL13 在预测长期影像学状态和进展方面优于目前使用的临床和血清学疾病标志物。在治疗 11 年后,CXCL13 水平高于 85 pg/ml 可预测 TSS 为 5 或更高的风险。与 CRP、DAS28CRP、SJC28 和 ACPA 状态相比,CXCL13 在预测 11 年关节破坏方面具有优势。结论 在早期 RA 中,单次测量基线血浆 CXCL13 在预测长期影像学状态和进展方面优于目前使用的临床和血清学疾病标志物。
