High prevalence of diabetes mellitus in patients with liver cirrhosis has been reported in many studies. The aim of our study was to evaluate the relationship of hepatic fibrosis and steatosis assessed by transient elastography with diabetes in patients with chronic liver disease. The study population consisted of 979 chronic liver disease patients. Liver fibrosis and steatosis were assessed by liver stiffness measurement (LSM) and controlled attenuation parameter (CAP) on transient elastography. Diabetes was diagnosed in 165 (16.9%) of 979 patients. The prevalence of diabetes had significant difference among the etiologies of chronic liver disease. Higher degrees of liver fibrosis and steatosis, assessed by LSM and CAP score, showed higher prevalence of diabetes (F0/1 [14%], F2/3 [18%], F4 [31%], P<0.001; S0/1 [15%], S2 [17%], S3 [26%], P=0.021). Multivariate analysis showed that the independent predictive risk factors for diabetes were hypertension (OR, 1.98; P=0.001), LSM F4 (OR, 1.86; P=0.010), male gender (OR, 1.60; P=0.027), and age>50 yr (OR, 1.52; P=0.046). The degree of hepatic fibrosis but not steatosis assessed by transient elastography has significant relationship with the prevalence of diabetes in patients with chronic liver disease.

OBJECTIVETo study the pathological and clinical features of nonalcoholic fatty liver disease (NAFLD).
METHODSGrades and stages of liver lesions in 41 patients with NAFLD were analyzed. The relationships between pathohistological features of the livers, serum biochemical parameters, ultrasound examination and other clinical data of the patients were studied.
RESULTSAmong the 41 patients with NAFLD (there were 21 with their liver fatty degeneration in grade 1, 15 in grade 2, and 5 in grade 3). There were 2 of grade 0, grade 1 had 25, grade 2 had 10, grade 3 had 3, and grade 4 had 1. Stage 0 of fibrosis was 20, stage 1 was 14, stage 2 was 4, stage 3 was 2, and stage 4 was 1. Degree of fatty degeneration was not positively associated with the body mass index (BMI) of the patients and the ultrasound findings in their livers. Grading of the inflammation was positively related to the alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels in the blood and ultrasound findings in their livers, but negatively to the platelet counts. Staging of fibrosis of the livers was positively related to the blood ALT, AST, GGT, and ALP, and negatively to triglyceride levels and platelet counts.
CONCLUSIONSDegree of liver fatty degeneration was not associated with grades of inflammation and staging of fibrosis of the liver. BMI, ALT and AST level, platelet counts, and ultrasound grades of fatty liver were associated with the liver histopathological changes of NAFLD patients. Liver biopsy is the essential way to make a diagnosis of NAFLD.

PURPOSE: We examined the relationship between portal venous velocity and hepatic-abdominal fat in patients with nonalcoholic fatty liver disease (NAFLD), using spectral Doppler ultrasonography (US) and magnetic resonance imaging (MRI). MATERIALS AND METHODS: In this prospective study, 35 patients with NAFLD and 29 normal healthy adults (control group) underwent portal Doppler US. The severity of hepatic steatosis in patients with NAFLD was assessed by MRI through chemical shift imaging, using a modification of the Dixon method. Abdominal (intra-abdominal and subcutaneous) fat was measured by MRI. RESULTS: The difference in portal venous velocity between the patients with NAFLD and the control group was significant (p < 0.0001). There was no correlation between the degree of abdominal or hepatic fat and portal venous velocity (p > 0.05). There were strong correlations between the hepatic fat fraction and subcutaneous adiposity (p < 0.0001), intraperitoneal fat accumulation (p = 0.017), and retroperitoneal fat accumulation (p < 0.0001). CONCLUSION: Our findings suggest that patients with NAFLD have lower portal venous velocities than normal healthy subjects.
