Abstract

Gout is the most common inflammatory arthritis characterized by painful disabling acute attacks. It is caused by hyperuricemia and deposition of urate crystals in and around the joints. Long-standing untreated hyperuricemia can lead to chronic arthritis with joint damage, tophi formation and urate nephropathy. Gout is associated with significant morbidity and health care associated cost. The goal of long-term therapy is to lower the serum urate level to promote dissolution of urate crystals, reduce recurrent acute gout flares, resolve tophi and prevent joint damage. Despite the presence of established gout treatment guidelines and effective medications to manage gout, patient outcomes are often poor. Etiology for these shortcomings is multifactorial including both physician and patient characteristics. Poor adherence to urate-lowering therapy (ULT) is prevalent and is a significant contributor to poor patient outcomes. This article reviews the treatment strategies for the management of hyperuricemia in chronic gout, gaps in quality of care in gout management, factors contributing to poor adherence to ULT and discusses potential interventions to achieve improved gout-related outcomes. These interventions include initiation of prophylactic anti-inflammatory medication when starting ULT, frequent follow-ups, regular serum urate monitoring and improved patient education, which can be achieved through pharmacist- or nurse-assisted programs. Interventions such as these could improve adherence to ULT and, ultimately, result in optimal gout-related outcomes.

摘要

痛风是最常见的炎性关节炎,其特征为疼痛性致残性急性发作。它由高尿酸血症及尿酸盐结晶在关节内外沉积所致。长期未经治疗的高尿酸血症可导致慢性关节炎伴关节损害、痛风石形成及尿酸盐肾病。痛风与显著的发病率及医疗相关费用有关。长期治疗的目标是降低血清尿酸水平,以促进尿酸盐结晶溶解,减少复发性急性痛风发作,消除痛风石并预防关节损害。尽管已有既定的痛风治疗指南及有效的痛风治疗药物,但患者的治疗效果往往不佳。这些不足的病因是多因素的,包括医生和患者的特征。对降尿酸治疗(ULT)依从性差的情况普遍存在,且是导致患者治疗效果不佳的重要因素。本文综述了慢性痛风高尿酸血症的治疗策略、痛风管理中医疗质量的差距、导致ULT依从性差的因素,并讨论了实现改善痛风相关结局的潜在干预措施。这些干预措施包括在开始ULT时启动预防性抗炎药物治疗、频繁随访、定期监测血清尿酸以及通过药剂师或护士辅助项目改善患者教育。诸如此类的干预措施可提高对ULT的依从性,并最终带来最佳的痛风相关结局。
