Abstract
Introduction: Hyporesponsiveness to erythropoiesis-stimulating agents (ESAs) in patients with anaemia of chronic kidney disease may lead to increased ESA doses to achieve target haemoglobin levels; however, elevated doses may be associated with increased mortality. Furthermore, patients with hyporesponsiveness to ESAs have poorer clinical outcomes than those who respond well to ESAs. Incidence and clinical characteristics of patients with ESA hyporesponsiveness were explored in a real-world setting.
Methods: This was a retrospective study of electronic medical records of adults with stage 5 chronic kidney disease receiving renal replacement therapy and ESA treatment, from 1 January 2015 to 31 December 2021. The primary objective was ESA hyporesponsiveness rate/1000 days, with a hyporesponsive event defined as ESA use at an elevated dose, according to National Institute for Health and Care Excellence (NICE) criteria. Other hyporesponsiveness definitions applied were erythropoietin resistance index-defined ESA hyporesponsiveness (ERI) Kidney Disease Improving Global Outcomes (KDIGO) and a clinical practicality algorithm.
Results: In total, 85,259 patients were included in the analysis; 59.9% were male, median (interquartile range) ESA starting dose was 733.3 (400.0, 1200.0) IU/week and follow-up duration was 2.2 (1.0, 4.2) years. Incidence of ESA hyporesponsiveness varied when applying different definitions; NICE 0.05/1000 days (5.2% of patients), ERI 0.40/1000 days (40.7%), KDIGO 0.15/1000 days (15.4%), and clinical practicality algorithm 0.48/1000 days (47.9%). ESA doses remained higher in hyporesponsive versus responsive patients, yet haemoglobin levels were similar between groups.
Conclusion: The results from this study, which applied multiple hyporesponsiveness definitions to a large, geographically diverse population of patients with anaemia of CKD, showed variation in ESA hyporesponsiveness incidence rates depending on definitions used and higher ESA doses in hyporesponsive versus responsive patients. These results underscore the need for individualised clinical assessment and thorough evaluation when considering ESA dose adjustments to reach haemoglobin targets.

导言：慢性肾脏病贫血患者对促红细胞生成药物（ESAs）反应低下，可能导致ESAs剂量增加，以达到目标血红蛋白水平；然而，剂量增加可能与死亡率增加有关。此外，与对ESAs反应良好的患者相比，对ESAs反应不佳的患者临床疗效较差。本研究在真实世界环境中探讨了ESA低反应患者的发病率和临床特征：这是一项回顾性研究，研究对象是2015年1月1日至2021年12月31日期间接受肾脏替代治疗和ESA治疗的5期慢性肾脏病成人患者的电子病历。主要目标是ESA低反应率/1000天，根据美国国家健康与护理优化研究所（NICE）的标准，低反应事件定义为ESA使用剂量升高。其他低反应性定义包括红细胞生成素抵抗指数定义的ESA低反应性（ERI）、肾病改善全球结果（KDIGO）和临床实用性算法：共有85259名患者纳入分析；59.9%为男性，ESA起始剂量中位数（四分位数间距）为733.3（400.0，1200.0）IU/周，随访时间为2.2（1.0，4.2）年。应用不同的定义时，ESA低反应的发生率有所不同：NICE为0.05/1000天（5.2%的患者），ERI为0.40/1000天（40.7%），KDIGO为0.15/1000天（15.4%），临床实用性算法为0.48/1000天（47.9%）。低反应患者的 ESA 剂量仍然高于有反应的患者，但两组患者的血红蛋白水平相似：本研究对大量不同地域的慢性肾脏病贫血患者采用了多种低反应定义，结果显示，ESA 低反应发生率因所采用的定义而异，低反应患者的 ESA 剂量高于反应患者。这些结果突出表明，在考虑调整ESA剂量以达到血红蛋白目标时，需要进行个体化临床评估和全面评价。本文图文摘要：NCT05530291.
期刊介绍：
Advances in Therapy is an international, peer reviewed, rapid-publication (peer review in 2 weeks, published 3–4 weeks from acceptance) journal dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of therapeutics and interventions (including devices) across all therapeutic areas. Studies relating to diagnostics and diagnosis, pharmacoeconomics, public health, epidemiology, quality of life, and patient care, management, and education are also encouraged.
The journal is of interest to a broad audience of healthcare professionals and publishes original research, reviews, communications and letters. The journal is read by a global audience and receives submissions from all over the world. Advances in Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an international and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of all scientifically and ethically sound research.
