Abstract:

Objective To investigate the correlation of serum pancreatic lipase(P-LIP) with nonalcoholic fatty liver disease(NAFLD) and the clinical significance for predicting hepatic fibrosis. Methods A total of 700 NAFLD patients diagnosed by abdominal ultrasonography and 310 healthy subjects (healthy control group)were enrolled,and their body parameters and hematological indices were determined,like height,body mass index,systolic blood pressure,diastolic blood pressure,P-LIP,amylase(AMY),alanine aminotransferase(ALT),aspartate aminotransferase(AST),gamma-glutamyltransferase(GGT),creatine kinase(CK),triglyceride(TG),total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C),fasting plasma glucose(FPG), uric acid(UA),serum iron(Fe),sialic acid(SA),high-sensitivity C-reactive protein(hs-CRP) and white blood cell(WBC). According to the guidelines for the diagnosis of metabolic syndrome (MS) issued by Chinese Diabetes Society of Chinese Medical Association in 2004,the NAFLD patients were classified into 2 groups,MS group and non-MS group. Spearman correlation analysis was used to evaluate the correlation of P-LIP levels with other parameters. Stepwise regression analysis was used to evaluate different P-LIP levels' risk for advanced hepatic fibrosis [fibrosis index based on 4 factors (FIB-4)≥1.3] in NAFLD patients. Results Compared with healthy control group,NAFLD group had significantly low levels of HDL-C and AMY,and the other parameters increased significantly(P<0.05). The P-LIP levels in MS group [26(4-208)U/L] were significantly lower than those in non-MS group [30(14-298)U/L] and healthy control group [36(5-201)U/L](P<0.05). P-LIP was positively correlated with HDL-C and AMY(r = 0.154 and 0.211,P<0.05),and it was negatively correlated with ALT,GGT,TG,FPG,UA,SA,hs-CRP and WBC(r = -0.171,-0.167,-0.223,-0.155,-0.201,-0.154 and -0.162,P<0.05). Stepwise regression analysis showed that serum P-LIP was an independent factor for predicting advanced hepatic fibrosis in NAFLD patients[odds ratio(OR)=2.356,95% confidence interval(CI):1.235-5.331]. Conclusions Serum P-LIP is closely correlated with NAFLD and could be used as an independent factor for predicting hepatic fibrosis in NAFLD patients.
