OBJECTIVE This prospective study investigates the efficacy of biologics in combination with methotrexate or leflunomide on juvenile idiopathic arthritis (JIA)- related temporomandibular joint (TMJ) arthritis measured by magnetic resonance imaging (MRI)-based inflammation score and deformity score. METHODS A prospective single center observational cohort study of 18 consecutive patients were performed between September 2018- April 2023. Inclusion criteria were: 1) Diagnosis of JIA, 2) MRI-verified TMJ arthritis leading to treatment with tumor necrosis factor inhibitor (TNFi), 3) MRI at 6 and 24 months after treatment initiation, 4) clinical follow-up contemporary with the MRI by a pediatric rheumatologist and an orthodontist. RESULTS We included 18 patients (89% females). At time of first MRI median age was 13.2 years (IQR 11.3-16.9), median disease duration was 7.8 years (IQR 3.4-11.1) and 4 received MTX/leflunomide. During the observation period, significant improvements were observed in TMJ movement pain (p=0.01), morning stiffness (p=0.004), opening capacity (p=0.03) and maximal incisal opening (p=0.006). The inflammation score decreased significantly from median 2 (IQR 1-3) at baseline to median 1(IQR 0-2) at 24 months, p=0.009. In 17 out of 36 TMJs (48%), the deformity score improved or remained stable and no significant increase in the median score was observed. CONCLUSION This is the first prospective observational study with evidence to support that the orofacial signs, symptoms and MRI-derived inflammation score in TMJ arthritis can be reduced by treatment with TNFi.

生物制剂对幼年特发性关节炎颞下颌关节炎症的影响。



目的 本前瞻性研究探讨生物制剂联合甲氨蝶呤或来氟米特治疗幼年特发性关节炎 (JIA) 相关颞下颌关节 (TMJ) 关节炎的疗效,通过基于磁共振成像 (MRI) 的炎症评分和畸形评分测量。方法 在 2018 年 9 月至 2023 年 4 月期间对连续 18 例患者进行了一项前瞻性单中心观察队列研究。纳入标准是:1) JIA 的诊断,2) MRI 验证的 TMJ 关节炎导致肿瘤坏死因子抑制剂 (TNFi) 治疗,3) 治疗开始后 6 个月和 24 个月的 MRI,4) 儿科风湿病学家和正畸医生与 MRI 同时进行的临床随访。结果 我们纳入了 18 例患者 (89% 为女性)。首次 MRI 时,中位年龄为 13.2 岁 (IQR 11.3-16.9),中位病程为 7.8 年 (IQR 3.4-11.1),4 例接受 MTX/来氟米特治疗。在观察期间,观察到 TMJ 运动疼痛 (p=0.01) 、晨僵 (p=0.004)、张开能力 (p=0.03) 和最大切口张开度 (p=0.006) 有显著改善。炎症评分从基线时的中位数 2 (IQR 1-3) 显著下降到 24 个月时的中位数 1 (IQR 0-2),p=0.009。在 36 例 TMJ 中,有 17 例 (48%) 的畸形评分有所改善或保持稳定,并且未观察到中位评分显着增加。结论 这是第一项有证据支持的前瞻性观察性研究,支持 TNFi 治疗可以降低 TMJ 关节炎的口面部体征、症状和 MRI 衍生的炎症评分。
