Abstract:Objective To compare the efficacy and safety of semaglutide and beinaglutide in the treatment of type 2 diabetes mellitus (T2DM) with concurrent polycystic ovary syndrome (PCOS).Methods A total of 153 T2DM patients with PCOS admitted to our hospital from July 2021 to August 2023 were selected, and were divided into the control group (77 cases) and the observation group (76 cases) according to the random number table method. The control group was administrated with beinaglutide injection, and the observation group was injected with semaglutide. Therapeutic effects were evaluated in both groups after three months of treatment. Changes in glucose and lipid metabolism indicators, sex hormones, peripheral blood factors, and adverse drug reactions were compared between the two groups before and after treatment.Results The differences in FPG, 2hPPG, HOMA-IR and HOMA-β levels before and after treatment in the observation group were higher than those in the control group (P < 0.05). The differences in TG and TC levels before and after treatment in the observation group were higher than those in the control group (P < 0.05). The differences in T, E2, LH, and FSH levels before and after treatment in the observation group were higher than those in the control group (P < 0.05). The differences in OM-1, MCP-1, IGF, and NSF-1 levels before and after treatment in the observation group were also higher than those in the control group (P < 0.05). The overall incidence of adverse drug reactions was 6.58% in the observation group and 5.19% in the control group, with no statistically significant difference between the two groups (P > 0.05).Conclusion Compared with beinaglutide, semaglutide demonstrates greater advantages in improving glucose and lipid metabolism, hormone levels, and peripheral blood factors in patients with T2DM and PCOS, and is considered safe and well-tolerated.
