The aim of this study was to assess changes in the estimated glomerular filtration rate (eGFR) in gouty patients with chronic kidney disease (CKD) using a "treat-to-target" (T2T) approach in gout. This multicenter observational retrospective study included patients diagnosed with gout and CKD stage 3 taking xanthine oxidase inhibitors (XOIs) (allopurinol or febuxostat) for at least 12 months. All patients were treated using a T2T strategy according to national gout guidelines to achieve the target levels of serum uric acid (sUA; < 5-6 mg/dl) within 6 months of the first visit. The primary outcome was to assess changes in eGFR. The effects of independent variables were analyzed over eGFR in a linear mixed-effects (LME) model. Fifty patients with gout and CKD stage 3 treated with XOIs with a T2T strategy for 12 months were included. Eighty-two percent of the patients achieved the sUA target during the study period. The improvement seen in eGFR was higher during the first 6 months, showing a median increase of 7.54 ml/min/m2 (SE = 1.25) and trending towards stability over 12 months. For every 1 mg/dl of decrease in sUA, an improvement of 1.5 ml/min/m2 in eGFR was observed (coefficient ± SE: - 1.58 ± 0.26) (p < 0.001) with no differences between type and dosage of XOIs treatment, colchicine administration, age, sex, and smoking status. A reduction in sUA levels using a T2T approach with XOIs at an optimal dose is possible and could help conserve and improve renal function in gouty patients with CKD stage 3.

一种针对目标的痛风治疗方法可对患有慢性肾脏疾病3期的患者提供肾脏保护作用。

这项研究的目的是评估痛风患者采用“治疗至目标”(T2T)方法评估慢性肾脏病(CKD)痛风患者估计肾小球滤过率(eGFR)的变化。这项多中心观察性回顾性研究包括诊断为痛风和CKD 3期的患者,服用黄嘌呤氧化酶抑制剂(XOIs)(allopurinol或非布索坦)至少12个月。所有患者均按照国家痛风指南采用T2T策略进行治疗,以在首次就诊后的6个月内达到血清尿酸(sUA; <5-6 mg / dl)的目标水平。主要结果是评估eGFR的变化。在线性混合效应(LME)模型中,通过eGFR分析了自变量的影响。包括五十名患有痛风和CKD 3期的患者,这些患者接受了采用T2T策略的XOI治疗12个月。在研究期间,有82%的患者达到了sUA目标。在前6个月,eGFR的改善更高,显示中位数增加7.54 ml / min / m2(SE = 1.25),并在12个月内趋于稳定。sUA每降低1 mg / dl,eGFR改善1.5 ml / min / m2(系数±SE:-1.58±0.26)(p <0.001),XOIs治疗的类型和剂量无差异,秋水仙碱的使用,年龄,性别和吸烟状况。使用T2T方法和最佳剂量的XOI可以降低sUA水平,并且可以帮助保护和改善CKD 3期痛风患者的肾功能。显示中位数增加7.54 ml / min / m2(SE = 1.25),并在12个月内趋于稳定。sUA每降低1 mg / dl,eGFR改善1.5 ml / min / m2(系数±SE:-1.58±0.26)(p <0.001),XOIs治疗的类型和剂量无差异,秋水仙碱的使用,年龄,性别和吸烟状况。使用T2T方法和最佳剂量的XOI可以降低sUA水平,并且可以帮助保护和改善CKD 3期痛风患者的肾功能。显示中位数增加7.54 ml / min / m2(SE = 1.25),并在12个月内趋于稳定。sUA每降低1 mg / dl,eGFR改善1.5 ml / min / m2(系数±SE:-1.58±0.26)(p <0.001),XOIs治疗的类型和剂量无差异,秋水仙碱的使用,年龄,性别和吸烟状况。使用T2T方法和最佳剂量的XOI可以降低sUA水平,并且可以帮助保护和改善CKD 3期痛风患者的肾功能。和吸烟状况。使用T2T方法和最佳剂量的XOI可以降低sUA水平,并且可以帮助保护和改善CKD 3期痛风患者的肾功能。和吸烟状况。使用T2T方法和最佳剂量的XOI可以降低sUA水平,并且可以帮助保护和改善CKD 3期痛风患者的肾功能。
