ABSTRACT
Objective To investigate the clinical features and prognosis related risk factors in nonalcoholic steatosis liver cirrhosis(NASLC).Methods From January 1st,2006 to December 31st, 2013,in a prospective cohort of 12 489 patients with liver cirrhosis set,174 patients were with NASLC and 306 patients with hepatitis B were the control.The patients were followed up every three months. The clinical data of patients were collected,including gender,age,height,body weight,blood pressure, history of hypertension,history of diabetes,family history of tumor,blood glucose level,high density lipoprotein cholesterol(HDL-C)level,low density lipoprotein cholesterol(LDL-C)level,triglyceride level,white blood cell,platelet,prothrombin time activity,total bilirubin,albumin,cholinesterase,blood urea nitrogen,creatinine,alpha-fetoprotein,abdominal ultrasound,abdominal computer tomography and endoscopy.Body mass index(BMI)and Child-Pugh scores were calculated.The differences between the two groups were analyzed in the incidence of ascites,hepatic encephalopathy,hepatorenal syndrome, esophageal varices bleeding,liver failure,hepatocellular carcinoma and mortality.Chi square test and t test were performed for statistical analysis.logistic regression analysis was used to analyze the risk factors associated with hepatocellular carcinoma in patients with NASLC.Results The proportion of female in NASLC group was higher than that in posthepatic cirrhosis group(56.0%,47/84 vs 28.7%,49/171), and the difference was statistically significant(χ2 =17.653,P<0.01).BMI,systolic pressure,diastolic pressure,level of fasting blood glucose,LDL-C,triglyceride,prothrombin time activity,albumin, cholinesterase,cases number of hypertension,diabetes and metabolic syndrome of NASLC group were all significantly higher than those of posthepatic cirrhosis group(t=6.267,4.091,5.773,2.914,1.877, 2.044,2.326,1.935 and 2.023;χ2=7.241,9.399 and 81.367;all P<0.05),however,serum levels of HDL-C,total bilirubin and creatinine were significantly lower than those of posthepatic cirrhosis group (t=6.127,8.487 and 3.261;all P < 0.05).T he three-year accumulative incidences of hepatic encephalopathy,hepatorenal syndrome and liver failure of NASLC group(8.3%,7/84;1.2%,1/84;0) were all lower than those of posthepatic cirrhosis control group(22.2%,38/171;9.9%,17/171 and 5.8%, 10/171;χ2 = 5.751,3.862 and 3.927,all P< 0.05).The three-year accumulative incidence of hepatocellular carcinoma of NASLC was 8.3%(7/84).The three-year accumulative incidence of mortality was lower than that of posthepatic cirrhosis group(2.4%,2/84 vs 13.5%,23/171;χ2 = 3.884,P=0.049).The results of logistic regression analysis showed that BMI(odds ratio(OR)= 1.469,95%confidence interval(CI)1.093 to 2.176,P=0.016)and diabetes(OR=1.734,95% CI 1.269 to 2.388, P=0.012)were independent risk factors associated with hepatocellular carcinoma in NASLC patients. Conclusions NASLC occurrs mainly in female with good liver function.BMI and diabetes are the risk factors associated with hepatocellular carcinoma in patients with NASLC.
