Abstract

OBJECTIVES

This study evaluated the effectiveness of Janus kinase inhibitors (JAKi) in patients with difficult-to-treat rheumatoid arthritis (D2T RA).

METHODS

This study included 220 patients with RA who were treated with JAKi. Sixty-two patients were naïve to biological disease-modifying antirheumatic drugs (bDMARDs)/JAKi (1st group), 57 patients were failure to one bDMARDs/JAKi (2nd group), and 101 patients were failure to ≥ 2 bDMARDs/JAKi. Of these 101 patients, 25 did not meet the D2T RA criteria (non-D2T RA group) and 76 met the D2T RA criteria (D2T RA group).

RESULTS

: DAS28-ESR was improved in all groups at 24 weeks (1st: P < .01, 2nd: P < .01, non-D2T RA: P = .01, D2TRA: P = .02), and improvement ratio of DAS28-ESR was not different between DT2RA group and 2nd (P = .73) or non-D2T RA group (P = .68). Glucocorticoid use [odds ratios: 8.67; 95% confidence interval (CI): 1.23-60.90; P = .03] and number of past bDMARD/JAKi uses ≥ 3 (odds ratios: 10.55; 95% CI: 1.39-80.30; P = .02) were risk factors for DAS28-ESR ≥ 3.2 at 24 weeks in the D2T RA group.

CONCLUSIONS

Clinical efficacy of JAKi in D2T RA group did not differ from that in 2nd and non-D2T RA groups. Glucocorticoid use and multiple bDMARD/JAKi failure were poor prognostic factors for D2T RA.

摘要

目的

本研究评估了Janus激酶抑制剂（JAKi）在治疗困难的类风湿关节炎（D2T RA）患者中的有效性。

方法

本研究纳入了220例接受JAKi治疗的类风湿关节炎患者。62例患者未使用过生物改善病情抗风湿药物（bDMARDs）/JAKi（第1组），57例患者对一种bDMARDs/JAKi治疗失败（第2组），101例患者对≥2种bDMARDs/JAKi治疗失败。在这101例患者中，25例不符合D2T RA标准（非D2T RA组），76例符合D2T RA标准（D2T RA组）。

结果

所有组在24周时DAS28-ESR均得到改善（第1组：P <.01，第2组：P <.01，非D2T RA组：P =.01，D2TRA组：P =.02），D2T RA组与第2组（P =.73）或非D2T RA组（P =.68）之间DAS28-ESR的改善率无差异。在D2T RA组中，使用糖皮质激素[比值比：8.67；95%置信区间（CI）：1.23 - 60.90；P =.03]和既往使用bDMARD/JAKi的次数≥3次（比值比：10.55；95%CI：1.39 - 80.30；P =.02）是24周时DAS28-ESR≥3.2的危险因素。
