Abstract:
Objective To investigate the serum retinol-binding protein 4 (RBP4) level in olanzapinetreated schizophrenia with non-alcoholic fatty liver disease (NAFLD) via a case-control study and to explore its relationship with NAFLD.Methods Schizophrenia receiving olanzapine treatment,with or without NAFLD were enrolled as cases (n=60) or controls (n=60).The serum retinol-binding protein 4,metabolic syndrome component including body mass index (BMI),waist-to-hip ratio (WHR),fasting plasma glucose (FPG),total cholesterol (TG),total glycerin (TC) and blood pressure were assayed.TyG index,CT value ratio of liver and spleen were used for insulin resistance or NAFLD diagnosis and severity assessment respectively.Results The serum level of RBP4 was significantly higher in cases than that in controls ((70± 13)mg/L vs (52±12)mg/L ; t =4.943,P＜0.01) and the same result was showed after influencing factor adjustment thru covariance analysis (F=16.797,P＜0.01).Moreover,cases had significantly higher TyG index,BMI,WHR,FPG,TG and systolic pressure (t=2.383-4.300,P＜0.05-0.01).Cases with severe or moderate NAFLD had significantly elevated serum RBP4 level compared with mild cases((79± 16) mg/L,(72±8) mg/L vs (63t9) mg/L,d =16.2,9.9 ; P＜0.01,0.05).A significantly negative correlation between RBP4 level and the CT value ratio of liver and spleen (r=-0.244,P＜0.05),and a significantly positive correlation between RBP4 level and TyG index,BMI,WHR,TG(r=0.197-0.244,all P＜0.05) were observed.The partial coefficient between RBP4 level and CT value of liver and spleen was significant with influence adjusted(r=-0.453,P＜0.01).Logistic regression showed that serum RBP4 level(β3=0.105,P＜0.01)and TyG index,hyperlipidemia,obesity,central obesity or high blood pressure (β =1.288-9.711,P＜ 0.05-0.01) were closely associated with NAFLD.Conclusion A heighten serum RBP4 level may be one of NAFLD risk factors in schizophrenia treated with olanzapine.
