Abstract：Objective: To investigate the clinical efficacy of tongxinluo capsule combined with irbesartan (Irb) in the treatment of early diabetic kidney disease (DKD) and the effect on the serum cystatin C (CysC), interleukin (IL)-18, endothelin (ET)-1 and nitric oxide (NO) levels. Methods: 138 cases of patients with early DKD admitted in our hospital from Jan. 2015 to Jan. 2017 were selected and divided into two groups on a random basis. The control group was treated with Irb, while the observation group was administrated with tongxinluo capsule in combination with Irb. The clinical efficacy, changes of serum CysC, IL-18, ET-1, NO levels before and after treatment and occurrence of adverse reactions were compared between the two groups. Results: After 12 weeks of treatment, the total effective rate of the observation group was significantly higher than that of the control group (P<0.05). Compared with those before treatment, the serum CysC, IL-18 and ET-1 levels of both groups at 12 weeks after treatment were remarkably decreased(P<0.01), while the NO levels of both groups at 12 weeks after treatment were remarkably increased (P< 0.01). The serum CysC, IL-18 and ET-1 levels of observation group were significantly lower, while the serum NO level was much higher than those of the control group(P<0.01). There was no statistic difference in the incidence of adverse reactions between the two groups (P>0.05). Conclusion: The combination of Tongxinluo capsule and erbesartan in the treatment of early DKD can effectively improve its clinical efficacy and improve renal function with high safety. It may significantly reduce the level of serum CysC, IL-18, ET-1, increase the level of serum NO, and then improve the microinflammatory state and vascular endothelial function of the body.
