Abstract:Objective To explore the clinical efficacy of calcitriol combined with candesartan in the treatment of early diabetic nephropathy and the effect on the expression level of serum anti-aging protein Klotho and Vaspin. Methods A total of 100 patients with early diabetic nephropathy who visited our hospital from January 2016 to January 2018 were selected, and were randomly divided into observation group and control group by use random number table method, with 50 patients in each group. The control group was treated with candesartan and the observation group was treated with combination of calcitriol and candesartan. The clinical efficacy, renal function, blood lipid, renal interstitial fibrosis, and serum Klotho and Vaspin expression levels of the two groups were compared. Results After treatment, the clinical efficiency in the observation group was 92% higher than 76% in the control group, and the difference was statistically significant (P?0.05); levels of Scr, BUN, UAER, VEGF, TGF-β1, Hcy, TC, TG and LDL were decreased in both groups, and the observation group was lower than the control group (P?0.05); there was no statistically significant difference between the two groups before and after HDL treatment (P?>?0.05). After treatment, the serum Klotho and Vaspin content in two group increased (P?0.05), which in the observation group were higher than those in the control group (P?0.05). Conclusion The combination of calcitriol and candesartan in the treatment of early diabetic nephropathy can significantly improve clinical efficacy, improve renal function, blood lipid and reduce renal fibrosis, and also increase serum Klotho and Vaspin levels, which is worthy of clinical reference.
