Abstract:Objective To explore the effects of Olmesartan combined with Rituximab on renal function, anti-M-type phospholipase A2 receptor (PLA2R) antibody, and angiopoietin-like protein-4 levels in patients with membrane-induced nephropathy. Methods A total of 72 patients with membranous nephropathy treated in Department of Rheumatology and Nephrology of Xuzhou Hospital of Traditional Chinese Medicine, Jiangsu Province from May 2019 to May 2022 were selected and divided into control group and observation group by random number table method, with 36 cases in each group. The control group was treated with Prednisone Acetate Tablets combined with Olmesartan, and the observation group was treated with Olmesartan Medoxomil Tablets combined with Rituximab. After six months of treatment, the therapeutic effect, renal function index, anti-M-type PLA2R antibody, angiopoietin-like protein-4, and helper T (Th) cell levels were compared between the two groups. The patients were followed up for three months and the adverse reactions were recorded in both groups. Results After six months of treatment, the efficacy of observation group was better than that of control group, and the difference was statistically significant (P<0.05). After six months of treatment, the levels of blood urea nitrogen, creatinine, uric acid, anti-M-type PLA2R antibody, angiopoietin-like protein-4, Th17 cells, Th1 cells, and Th2 cells in two groups were lower than those before treatment, and those of observation group were lower than those of control group, the differences were statistically significant (P<0.05). There was no significant difference in the total incidence of adverse reactions between the two groups (P>0.05). Conclusion Olmesartan combined with Rituximab in the treatment of membrane nephropathy can improve the renal function of patients, reduce the levels of anti-M-type PLA2R antibody and angiopoietin-like protein-4, and improve the therapeutic effect of patients.
