The prevalence of chronic kidney disease (CKD) has increased and will continue to increase in the United States and worldwide. This is alarming considering that CKD is an irreversible condition and patients who progress to chronic kidney failure have reduced quality of life and high mortality rates. As such, it is imperative to identify modifiable risk factors to develop strategies to slow CKD progression. One such factor is hyperuricemia. Recent observational studies have associated hyperuricemia with kidney disease. In addition, hyperuricemia is largely prevalent in patients with CKD. Data from experimental studies have shown several potential mechanisms by which hyperuricemia may contribute to the development and progression of CKD. In this article, we offer a critical review of the experimental evidence linking hyperuricemia to CKD, highlight gaps in our knowledge on the topic as it stands today, and review the observational and interventional studies that have examined the potential nephroprotective effect of decreasing uric acid levels in patients with CKD. Although uric acid also may be linked to cardiovascular disease and mortality in patients with CKD, this review focuses only on uric acid as a potential therapeutic target to prevent kidney disease onset and progression.
慢性肾脏病(CKD)的患病率在美国和全球范围内都有所增加,并将继续增加。这令人担忧,因为 CKD 是一种不可逆转的疾病,进展为慢性肾衰竭的患者生活质量降低,死亡率高。因此,确定可改变的危险因素以制定减缓 CKD 进展的策略至关重要。其中一个因素是高尿酸血症。最近的观察性研究表明,高尿酸血症与肾脏疾病有关。此外,高尿酸血症在 CKD 患者中很常见。实验研究数据表明,高尿酸血症可能通过多种潜在机制导致 CKD 的发生和进展。在本文中,我们对将高尿酸血症与 CKD 联系起来的实验证据进行了批判性回顾,突出了目前我们在该主题上知识的空白,并回顾了观察性和干预性研究,这些研究检查了降低 CKD 患者尿酸水平的潜在肾脏保护作用。尽管尿酸也可能与 CKD 患者的心血管疾病和死亡率有关,但本综述仅关注尿酸作为预防肾脏疾病发生和进展的潜在治疗靶点。
