Abstract:
Objective
To investigate the efficacy of sodium-glucose cotransporter 2 inhibitor(SGLT2i) for idiopathic membranous nephropathy and its effect on Th1/Th2 ratio.
Method
A singlecenter randomized controlled study was conducted by selecting 48 patients with idiopathic membranmembranic nephropathy who were diagnosed by renal biopsy or anti-phospholipase A2 receptor antibody detection and received initial formal treatment in Guiyang First People's Hospital from January 2022 to December 2023. The patients were randomly divided into two groups,a group of angiotensin II receptor blocker (ARB) combined with SGLT2i (treatment group,oral irbesartan 300 mg/d and dagliprazin 10 mg/d),and an ARB group (control group,oral irbesartan only 300 mg/d) with 24 patients in each.Demographic data,indicators of blood lipid,blood glucose,renal function,as well as T lymphocyte subsets Th1/Th2 ratio were collected,which was re-examined at 4 weeks,8 weeks,and 12 weeks after the treatment. The efficacy of therapy and its effect on Th1/Th2 ratio in the two groups were compared.
Results
The total effective rate of the treatment group was higher than that of the control group (95. 93% vs 70.83%, P <0.05). After treating for 4 weeks,8 weeks,and 12 weeks,the treatment group showed lower levels of 24h urinary protein than the control group [(2081.24 ±977.51) mg vs (2577.25 ±1286.44) mg,(1776.50 ± 676. 24) mg vs. (2163. 25 ± 620. 44) mg,(812. 44 ± 383. 25) mg vs (1681. 21 ±477.58) mg,P <0.001]. Compared with the control group,the treatment group showed higher levels of serum albumin [(37.53 ±3.87) g/L vs (32.52 ±3.69) g/L,(38.12 ±4.13) g/L vs (33.26 ±4.01) g/L,P <0.001] after treating for 8 weeks and 12 weeks,lower level of total cholesterol after treating for 12 weeks [(5.12 ±0.84) mmol/L vs (6.41 ±0.62) mmol/L,P <0.001],and also lower levels of triglycerides after treating for 8 weeks and 12 weeks [(1.62 ±0.81) mmol/L vs (2.01 ±0.53) mmol/L,and (1.50 ±0.91) mmol/L vs (1.99 ±0.74) mmol/L,P <0.001]. Besides,the Th1/Th2 ratio in the treatment group was higher than that in the control group after treating for 12 weeks [(1.01 ±0.31) vs(0.38 ±0.19),P <0.001].
Conclusion
SGLT2i could reduce proteinuria,improve lipid metabolism,and increase Th1/Th2 ratio in the patients with idiopathic membranous nephropathy.
