Patients with type 2 diabetes often face early tubular injury, necessitating effective treatment strategies. This study aimed to evaluate the impact of the SGLT2 inhibitor empagliflozin on early tubular injury biomarkers in type 2 diabetes patients with normoalbuminuria.
A randomized controlled clinical study comprising 54 patients selected based on specific criteria was conducted. Patients were divided into an intervention group (empagliflozin, n = 27) and a control group (n = 27) and treated for 6 weeks. Tubular injury biomarkers KIM-1 and NGAL were assessed pre- and post-treatment.
Both groups demonstrated comparable baseline characteristics. Post-treatment, fasting and postprandial blood glucose levels decreased similarly in both groups. The intervention group exhibited better improvements in total cholesterol, low-density lipoprotein, and blood uric acid levels. Renal function indicators, including UACR and eGFR, showed greater enhancements in the intervention group. Significant reductions in KIM-1 and NGAL were observed in the intervention group.
Treatment with empagliflozin in type 2 diabetes patients with normoalbuminuria led to a notable decrease in tubular injury biomarkers KIM-1 and NGAL. These findings highlight the potential of SGLT2 inhibitors in early tubular protection, offering a new therapeutic approach.
2型糖尿病患者常面临早期肾小管损伤,需要有效的治疗策略。本研究旨在评估钠-葡萄糖协同转运蛋白2(SGLT2)抑制剂恩格列净对正常白蛋白尿的2型糖尿病患者早期肾小管损伤生物标志物的影响。
进行了一项随机对照临床研究,纳入了54例根据特定标准选择的患者。患者分为干预组(恩格列净,n = 27)和对照组(n = 27),并接受6周治疗。在治疗前后评估肾小管损伤生物标志物肾损伤分子-1(KIM-1)和中性粒细胞明胶酶相关脂质运载蛋白(NGAL)。
两组患者的基线特征相当。治疗后,两组的空腹和餐后血糖水平均有相似程度的下降。干预组的总胆固醇、低密度脂蛋白和血尿酸水平改善更佳。包括尿白蛋白肌酐比值(UACR)和估算肾小球滤过率(eGFR)在内的肾功能指标在干预组有更大程度的改善。干预组的KIM-1和NGAL显著降低。
恩格列净治疗正常白蛋白尿的2型糖尿病患者可显著降低肾小管损伤生物标志物KIM-1和NGAL。这些发现凸显了SGLT2抑制剂在早期肾小管保护方面的潜力,提供了一种新的治疗方法。
