Clinical trial of semaglutide and saxagliptin combined with metformin in the treatment of patients with type 2 diabetes mellitus with abdominal obesity
Objective To observe the effects and safety of semaglutide and saxagliptin combined with metformin in the treatment of type 2 diabetes mellitus(T2DM)with abdominal obesity(AO).Methods The data of patients with T2DM and AO were retrospectively analyzed.Patients with T2DM and AO were divided into semaglutide group and saxagliptin group according to the cohort method.Both groups were given metformin orally,0.5 g a time,tid.On this basis,the semaglutide group was injected with semaglutide,0.25 mg a time,2 weeks later,the dose was adjusted to 0.5 mg a time,qw.The saxagliptin group was given oral administration of saxagliptin on the basis of metformin,5 mg a time,qd.All patients received 3 months of treatment.Glucose metabolism indexes,pancreatic islet function indexes,adipokines and adverse drug reactions were compared between the groups.Results There were 48 cases in semaglutide group and 49 cases in saxagliptin group.After treatment,the levels of fasting plasma glucose(FPG)in the semaglutide group and the saxagliptin group were(7.45±1.22)and(7.98±1.30)mmol·L-1;the levels of 2 h plasma glucose(2 h PG)were(9.78±1.64)and(10.55±1.82)mmol·L-1;the levels of hemoglobin A1c(HbA1c)were(5.66±0.94)and(6.25±0.87)％;the levels of fasting insulin(FINS)were(29.12±2.46)and(34.34±7.15)pmol·L-1;the levels of fasting C-peptide(FC-P)were(292.66±67.53)and(319.03±77.92)pmol·L-1;homeostatic model assessment-insulin resistance(HOMA-IR)were 2.51±0.78 and 2.94±0.89;homeostatic model assessment-β(HOMA-β)were 51.74±15.31 and 43.72±14.56;levels of Irisin were(4.56±0.32)and(4.17±0.54)ng·L-1;the levels of spexin(SPX)were(0.71±0.15)and(0.64±0.17)ng·mL-1;the levels of asprosin(ASP)were(1.22±0.16)and(1.34±0.25)μg·L-1.The above indexes were significantly different between semaglutide group and saxagliptin group(all P＜0.05).The total incidence rates of adverse drug reactions in semaglutide group and saxagliptin group were 10.42％(5 cases/48 cases)and 2.04％(1 case/49 cases),without statistically significant difference(P＞0.05).Conclusion The combination of semaglutide and metformin can lower blood glucose and in patients with T2DM and AO more significantly,and improve pancreatic function and adipokines,with good safety.
