Abstract
OBJECTIVE
To explore the efficacy of epalrestat (Ep) combined with alprostadil (Alp) in the treatment of diabetic nephropathy (DN) and its impacts on renal fibrosis (RF) and inflammation and oxidative stress (OS)-related factors.
METHODS
In this retrospective study, 120 patients with DN treated in the Cangzhou Central Hospital from January 2020 to January 2021 were selected as the research subjects. Among them, 80 cases treated with Ep combined with Alp were assigned to group A, and the rest 40 patients treated with Alp only were assigned to group B. The two groups were compared with respect to the following items: serum OS indexes (malondialdehyde, MDA; superoxide dismutase, SOD; total antioxidant capacity, TAOC), inflammatory factors (tumor necrosis factor-α, TNF-α; interleukin-2, IL-2), RF index transforming growth factor-β1 (TGF-β1), urinary protein indexes (urinary albumin excretion, UAE; serum albumin, ALB), blood glucose (fasting blood glucose, FBG), fasting C-peptide, postprandial 2hC peptide levels, overall response rate (ORR) and incidence of adverse reactions.
RESULTS
Compared with group B, the levels of MDA, TNF-α, IL-2 and TGF-β1 were lower, while SOD and TAOC were higher in group A. In addition, ALB was higher, while UAE and FBG were lower in group A as compared with group B. Moreover, group A had a higher ORR and fewer adverse reactions as compared with group B.
CONCLUSION
The combined therapy of Ep and Alp is more effective in the treatment of DN. This combination can effectively reduce RF and better alleviate inflammation and OS.
