: Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disease, which affects joints as well as extra-articular tissues. In the last decades, increasing targeted therapeutic options dramatically improved RA management by doubling the rate of patients achieving clinical remission. Currently, there is a need for management strategies aimed at limiting treatment-related adverse events and costs in good responders.: Data on de-escalation of biologic drugs (especially for anti-TNF agents) are mainly available from post-hoc analyses of randomized controlled trials and from registry-based observational studies. This narrative review illustrates the rationales for dose tapering and expands to provide an overview of the efficacy of the different available strategies for reducing the exposure to biologic drugs in patients achieving a sustained clinical response. Selected studies are discussed as illustrative examples.: Withdrawal of biologic therapy might be attempted in limited patients with very early RA; conversely, established RA is more suitably managed with a progressive decrease of drug regimen, by either dose reduction or injection/infusion spacing. Further studies investigating potential factors predicting post-tapering disease relapse are warranted, in order to better identify the best candidates for a decreased-dose approach.
类风湿关节炎(RA)是一种慢性、系统性自身免疫性疾病,不仅会影响关节,还会影响关节外组织。在过去几十年中,越来越多的靶向治疗选择通过将达到临床缓解的患者比例提高一倍,显著改善了 RA 的治疗管理。目前,需要制定管理策略,旨在限制良好应答者的治疗相关不良事件和成本。
关于生物药物(尤其是抗 TNF 药物)降阶梯的数据主要来自随机对照试验的事后分析和基于注册的观察性研究。本叙述性综述阐述了剂量逐渐减少的原理,并扩展提供了不同可用策略的疗效概述,这些策略旨在减少达到持续临床缓解的患者对生物药物的暴露。选择的研究被讨论作为说明性的例子。
在非常早期的 RA 中,可以尝试在有限的患者中停用生物治疗;相反,对于已确立的 RA,更适合通过减少药物剂量或注射/输注间隔来逐渐减少药物方案。有必要进一步研究潜在的预测停药后疾病复发的因素,以便更好地确定适合减少剂量方法的最佳人选。
