ABSTRACT

Objective:To evaluate the clinical curative effect of self-made Lishi Qufeng Juanbi Decoction combined with Febuxostat tablet on uric acid nephropathy (UAN).Methods:Randomized controlled trial. A total of 150 patients with UAN in Yixing Hospital of Traditional Chinese Medicine were enrolled as the observation objects between October 2019 to October 2021. According to random number table method, they were divided into two groups, 75 in each group. The control group was treated with Febuxostat tablets on basis of routine diet intervention, while the observation group was treated with self-made Lishi Qufeng Juanbi Decoction on basis of control group. All were continuously treated for 6 months. TCM syndromes were scored before and after treatment. The levels of serum uric acid (SUA) and creatinine (SCr) were detected by full-automatic biochemical analyzer, and levels of serum CRP, IL-6 and IL-8 were detected by ELISA. The 24h urine was collected to detect 24 h urine protein quantitation. The adverse events were recorded, and clinical curative effect was evaluated.Results:There were significant differences in total response rate between observation group and control group [93.33% (70/75) vs. 80.00% (60/75); χ2=5.77, P=0.016]. After treatment, scores of waist soreness-fatigue and frequent nocturia in observation group were significantly lower than those in the control group ( t=9.17, 2.67, P<0.01), and frequency of joint swelling pain was significantly lower than that of the control group ( t=9.49, P<0.01). The levels of serum SUA and SCr, and 24 h urine protein quantitation in observation group were significantly lower than those in the control group ( t=3.38, 2.49, 12.55, P<0.01 or P<0.05), and levels of CRP, IL-6 and IL-8 were significantly lower than those in the control group ( t=5.44, 4.15, 9.61, P<0.01). There was no significant difference in incidence of adverse reactions between observation group and control group [4.00% (3/75) vs. 10.67% (8/75); χ2=2.45, P=0.117]. Conclusion:The self-made Lishi Qufeng Juanbi Decoction combined with Febuxostat tablets can promote uric acid metabolism, improve high uric acid environment, protect renal function, inhibit the release of inflammatory factors, improve curative effect and reduce adverse reactions in UAN patients.
