Hyaluronic acid (HA), a fundamental component of the extracellular matrix, is associated with chronic liver diseases. The aim of this study was to investigate quantitative HA measurement as a noninvasive marker for steatosis and fibrosis staging in nonalcoholic fatty liver disease (NAFLD) with biopsy evidence.In this study, 52 NAFLD patients with biopsy evidence and who met the inclusion criteria were included. Hepatic enzyme levels, HA levels, and other laboratory findings were examined. In addition, the degree of steatosis was determined via computed tomography (CT).According to the degree of steatosis, HA levels were 29.17±22.66, 39.85±60.28, and 32.05±19.40, respectively, and no significant difference was found between the groups (p=0.584). In addition, HA levels were not found to be significant according to the degrees of steatohepatitis (p=0.860). However, a statistically significant relationship was found between steatosis levels detected by CT and biopsy (p0.01).Serum HA level, other biochemical parameters, and steatosis severity measurement via CT did not appear to have any diagnostic value for nonalcoholic steatohepatitis. In this context, novel markers that may be useful for NAFLD diagnosis and severity assessment in risky individuals should be investigated.

In this study, we aimed to investigate the relationship between the histological features of nonalcoholic fatty liver disease (NAFLD) and serum insulin-like growth factor-1 (IGF-1) and insulin-like growth factor-binding protein-5 (IGFBP-5) to determine the usefulness of this relationship in clinical practice.Serum samples were collected from 92 patients with biopsy-proven NAFLD and 51 healthy controls and serum levels of IGF-1 and IGFBP-5 were assayed by enzyme-linked immunosorbent assay.Serum IGFBP-5 levels were correlated with liver steatosis, fibrosis, and nonalcoholic steatohepatitis scores. IGF-1 levels were significantly decreased in patients with moderate-to-severe fibrosis compared with patients with no or mild fibrosis.Serum IGFBP-5 levels may be useful to differentiate both advanced fibrosis and definite nonalcoholic steatohepatitis from other NAFLD groups. Also, serum IGF-1 levels may be useful to differentiate advanced fibrosis in patients with NAFLD.

BACKGROUND/AIMS Fibrinogen-like protein 2 (fgl2), has recently been identified as a new member of the fibrinogen-like family of proteins. In this study we assayed plasma levels of fgl2 in patients with biopsy proven non-alcoholic fatty liver disease (NAFLD) and examined their association with clinical, biochemical and histological phenotypes. METHODOLOGY Levels of plasma fgl2 were measured by enzyme linked immunosorbent assay and compared between the study groups. Moreover, concentrations of fgl2 were assessed in relation to the general characteristics of the study participants and the results of the liver biopsy. RESULTS Levels of fgl2 were significantly higher in patients with definite non-alcoholic steatohepatitis (NASH) (788±190pg/mL, p

BACKGROUND & AIMS: Tenofovir disoproxil fumarate (TDF), a nucleotide analogue and potent inhibitor of hepatitis B virus (HBV) polymerase, showed superior efficacy to adefovir dipivoxil in treatment of chronic hepatitis B through 48 weeks. We evaluated long-term efficacy and safety of TDF monotherapy in patients with chronic hepatitis B who were positive or negative for hepatitis B e antigen (HBeAg+ or HBeAg-). METHODS: After 48 weeks of double-blind comparison of TDF to adefovir dipivoxil, patients who underwent liver biopsy were eligible to continue the study on open-label TDF for 7 additional years; data presented were collected up to 3 years (week 144) from 85% of participants. Primary efficacy end points at week 144 included levels of HBV DNA and alanine aminotransferase, development of resistance mutations, and presence of HBeAg or hepatitis B surface antigen (HBsAg). RESULTS: At week 144, 87% of HBeAg- and 72% of HBeAg+ patients treated with TDF had levels of HBV DNA
