Objective To explore the effects of metformin on glucolipid metabolism and renal function in patients with schizophrenia(SCH)after olanzapine treatment.Methods A retrospective analysis was performed on the case data of patients with metabolic syndrome induced by metformin and olanzapine treatment by cohort method.On basis of routine treatment(olanzapine,initial dose:10 mg·d-1,maximum dose≤ 20 mg·d-1),patients in high-dose group were given oral metformin tablets 750 mg(qd),while patients in low-dose group were given metformin tablets 250 mg(qd)for 1 month.The levels of fasting plasma glucose(FPG),glycosylated hemoglobin(HbA1c),high density lipoprotein cholesterol(HDL-C),low density lipoprotein cholesterol(LDL-C),total cholesterol(TC),triglyceride(TG),C-reactive protein(CRP)and tumor necrosis factor-α(TNF-α)before treatment and at 1 month after treatment,and safety evaluation were compared between the two groups.Results 43 cases in the high-dose group and 37 cases in the low-dose group.After treatment,FPG levels in low-dose group and high-dose group were(4.25±1.07)and(3.81±0.72)mmol·L-1,HbA1c levels were(5.10±0.54)%and(4.86±0.41)%,TC levels were(4.22±0.49)and(3.29±0.68)mmol·L-1,TG levels were(1.93±0.32)and(1.05±0.27)mmol·L-1,LDL-C levels were(3.26±0.68)and(2.89±0.43)mmol·L-1,HDL-C levels were(0.92±0.27)and(1.27±0.35)mmol·L-1,BUN levels were(4.71±0.90)and(5.08±1.49)mmol·L-1,Cr levels were(61.28±9.71)and(65.43±9.26)μmol·L-1,β2-MG levels were(1.72±0.46)and(1.97±0.55)μg·L-1,CRP levels were(6.20±0.87)and(10.85±1.42)mg·L-1,TNF-αlevels were(726.49±201.26)and(1 030.14±253.97)pg·mL-1,and the differences were statistically significant(all P<0.05).The incidence of adverse drug reactions in high-dose group was higher than that in low-dose group(32.56%vs 13.51%,P<0.05).Conclusion Metformin can effectively improve glucolipid metabolism and renal function in SCH patients after olanzapine treatment.Low-dose metformin has higher treatment safety.
