The aim of this study was to describe dose regimens, dose escalation and clinical outcomes in TNF-α inhibitor (TNFi)-naive patients with PsA treated with infliximab in routine rheumatology care.
We conducted an observational cohort study based on the nationwide Danish Rheumatologic Database (DANBIO) and Center for Rheumatology Research (ICEBIO) registries. Stratified by country, characteristics of patients treated with ≤3 mg infliximab/kg body weight, 3-5 mg/kg or ≥5 mg/kg every 8 weeks were described. Outcomes were evaluated by ACR 20%, 50% and 70% (ACR20/50/70) responses and European League Against Rheumatism good response after 6 months, disease activity after 12 months, Kaplan-Meier plots and regression analyses.
Four hundred and sixty-two patients (376 Danish, 86 Icelandic) received treatment with infliximab. In Danish patients, the starting dose was ≤3 mg/kg in 110 patients (29%), 3-5 mg/kg in 157 (42%), ≥5 mg/kg in 38 (10%) and unregistered in 71 (19%). In Icelandic patients, corresponding numbers were 64 (74%), 17 (27%), 0 (0%) and 5 (6%). Patients with a higher body weight received lower doses per kilogram. Danish patients received higher doses than Icelandic patients at baseline [median 3.1 (interquartile range 3.0-3.8) vs 2.3 (2.1-2.9) mg/kg, P < 0.05] and after 12 months [3.3 (3.0-4.5) vs 2.9 (2.2-3.5) mg/kg, P < 0.0001]. After 12 months, 58% of Danish and 66% of Icelandic patients maintained treatment. Danish patients had shorter drug survival than Icelandic patients (1183 vs 483 days). In univariate analyses stratified by country, time until dose escalation, response rates, drug survival and 1-year's disease activity were independent of starting dose. Drug survival was shorter among patients not receiving concomitant MTX.
In clinical practice, > 70% of Icelandic and Danish PsA patients treated with infliximab received sustained doses below the 5 mg/kg every 8 weeks recommended in international guidelines. Lower starting doses did not affect drug survival or response.
本研究旨在描述在常规风湿病护理中接受英夫利昔单抗治疗的初治银屑病关节炎（PsA）患者的给药方案、剂量递增情况及临床结局。
我们基于丹麦全国风湿病数据库（DANBIO）和风湿病研究中心（ICEBIO）登记处进行了一项观察性队列研究。按国家分层，描述了每8周接受≤3mg英夫利昔单抗/千克体重、3 - 5mg/kg或≥5mg/kg治疗的患者特征。通过美国风湿病学会（ACR）20%、50%和70%（ACR20/50/70）反应、6个月后的欧洲抗风湿病联盟良好反应、12个月后的疾病活动度、Kaplan - Meier曲线和回归分析来评估结局。
462例患者（376例丹麦患者，86例冰岛患者）接受了英夫利昔单抗治疗。在丹麦患者中，起始剂量≤3mg/kg的有110例（29%），3 - 5mg/kg的有157例（42%），≥5mg/kg的有38例（10%），未记录的有71例（19%）。在冰岛患者中，相应数字分别为64例（74%）、17例（27%）、0例（0%）和5例（6%）。体重较高的患者每千克体重接受的剂量较低。丹麦患者在基线时接受的剂量高于冰岛患者[中位数3.1（四分位间距3.0 - 3.8）mg/kg对2.
