摘要:

目的·探讨小剂量非布司他治疗慢性肾脏病(chronic kidney disease,CKD)合并无症状高尿酸血症(hyperuricemia,HUA)的高龄患者的效果、安全性及对肾功能的影响。方法·采用前瞻性队列研究,选取2021年2月—2021年7月在浙江省人民医院望江山院区住院并符合入组标准的102例高龄患者作为研究对象,根据药物使用剂量分为小剂量组(20 mg/d)、正常剂量组(40 mg/d)和对照组(未予药物治疗,生活方式干预为主)。总疗程3个月。计算各组患者每个月血尿酸(serum uric acid,SUA)达标率,收集并计算患者基线及治疗1、3个月后的SUA、血肌酐(serum creatinine,Scr)、内生肌酐清除率(creatinine clearance rate,Ccr)、估算的肾小球滤过率(estimated glomerular filtration rate,eGFR)等指标的变化,其中eGFR1、eGFR2的计算分别采用简化的肾脏病饮食改良研究公式及慢性肾脏病流行病学协作公式。同时观察药物引起的心脑血管事件、痛风、过敏等不良反应。采用χ2检验比较性别构成、基础疾病、用药情况的组间差异,采用单因素方差分析(one-way ANOVA)比较SUA、Scr、Ccr、eGFR1、eGFR2的组间差异。结果·治疗1、2、3个月后,小剂量组和正常剂量组的SUA达标率分别93.8%、93.8%、90.6%和93.8%、93.8%、96.9%。相较于对照组,上述2组SUA水平显著降低(均P=0.000)。此外,治疗3个月后小剂量组的Ccr、eGFR1、eGFR2高于基线值(P=0.006,P=0.013,P=0.015)及对照组同期水平(P=0.019,P=0.020,P=0.021)。同时,小剂量组和正常剂量组SUA的下降幅度差异无统计学意义,但均显著大于对照组(均P=0.000)。小剂量组Ccr、eGFR1、eGFR2的升高幅度均较对照组显著增加(P=0.004,P=0.002,P=0.003),与正常剂量组相比差异无统计学意义。所有患者观察期间均未出现严重不良反应。结论·小剂量和正常剂量非布司他对CKD合并无症状HUA的高龄患者的降尿酸疗效相当,均可获得较高的SUA达标率,并可一定程度改善肾功能,且不良反应少,安全性高。建议非布司他干预无症状HUA可从小剂量开始。

Abstract:

Objective·To investigate the efficacy, safety and effect on renal function of low-dose febuxostat in the treatment of elderly patients with chronic kidney disease (CKD) complicated with asymptomatic hyperuricemia (HUA).

Methods·In this prospective cohort study, a total of 102 elderly patients who were hospitalized in the Wangjiangshan Branch, Zhejiang Province People's Hospital from February 2021 to July 2021 and met the enrollment conditions were selected. They were divided into low dose group (20 mg/d), normal dose group (40 mg/d) and control group (without urate-lowering drug, mainly lifestyle intervention). The total course of treatment was 3 months. The control rates of serum uric acid (SUA) were calculated in each group monthly. The changes of SUA, serum creatinine (Scr), creatinine clearance rate (Ccr) and estimated glomerular filtration rate (eGFR) were collected and calculated at baseline and after 1 and 3 months of treatment. Meanwhile, eGFR1 was calculated by the simplified diet in renal disease (MDRD) equation, and eGFR2 was calculated by the chronic kidney disease epidemiology collaboration (CKD-EPI) equation. At the same time, cardiovascular and cerebrovascular events, gout attack, allergy and other adverse events caused by febuxostat were recorded. χ2 test was used to compare the differences in gender composition, basic disease and drug use among the three groups. One-way ANOVA was used to compare the differences in SUA, Scr, Ccr, eGFR1 and eGFR2 among the three groups.

Results·After 1, 2 and 3 months of treatment, the control rates of SUA in the low dose group and normal dose group were 93.8%, 93.8%, 90.6% and 93.8%, 93.8%, 96.9%, respectively. The SUA levels in the above two groups were significantly decreased, compared with the control group (all P=0.000). Ccr, eGFR1, eGFR2 in the low dose group were higher than those at baseline (P=0.006, P=0.013, P=0.015) and those in the control group (P=0.019, P=0.020, P=0.021). There were no significant differences in the decrease of SUA between the normal dose group and the low dose group, but they were significantly greater than those in the control group (all P=0.000). The increase of Ccr, eGFR1 and eGFR2 in the low dose group was significantly higher than that in the control group (P=0.004, P=0.002, P=0.003), but the difference was not statistically significant compared with the normal dose group. Severe adverse events specific to febuxostat were not observed.

Conclusion·Low dose and normal dose of febuxostat both have a similar urate-lowering efficacy in elderly patients with CKD complicated with asymptomatic HUA, getting a high control rate of SUA and improving renal function without serious adverse events. It is suggested a low dose of febuxostat at the beginning of the clinical intervention of asymptomatic HUA.
