Abstract
Background and aim
Total glucosides of paeony (TGP), an active compound extracted from dried roots of Paeonia lactiflora Pall, have anti-inflammatory effects. This study investigated the efficacy and safety of TGP for treating diabetic kidney disease (DKD) in type 2 diabetes mellitus patients.
Methods
An open-label, prospective, randomized, parallel-group, single-site study involving 76 patients with DKD. Patients were randomized into two groups: losartan group (n = 38), treated with losartan 100 mg/day for 6 months and TGP group (n = 38), treated with TGP 1800 mg/day and losartan 100 mg/day for 6 months. Serum hs-CRP, MCP-1, and TNF-α were determined before and after treatment. Urinary albumin excretion rate (UAER), fasting blood glucose, serum creatinine, and lipid profiles were examined.
Results
At the end-point, UAER decreased in the TGP group compared with baseline. UAER in the losartan group decreased to a level lower than before treatment. The rate of decline in the losartan group was significantly lower than the TGP group. There were no significant differences in serum creatinine and albumin levels between TGP and losartan groups at the end-point. Serum hs-CRP, MCP-1, and TNF-α levels were significantly lower in both groups after treatment. After treatment, serum hs-CRP, MCP-1, and TNF-α in the TGP group decreased more than the losartan group. Positive correlations were observed between UAER and hs-CRP, MCP-1, and TNF-α. No statistically significant difference in side effects was observed between groups.
Conclusion
Our study showed that TGP treatment could reduce the albuminuria and inflammatory markers in type 2 diabetes mellitus patients with DKD.
