Abstract

Objective: The objectives of this study were to investigate the use of non-invasive biochemical markers to evaluate the severity of liver fibrosis in patients with non-alcoholic steatohepatitis (NASH). Methods: This was a cross-sectional study of patients with histopathologically confirmed NASH between January 2005 and December 2006. The patients'characteristics were recorded and the body mass index was calculated for each patient. All patients underwent ultrasound-guided liver biopsy and a fibrosis assessment was performed using the Brunt criteria. The non-invasive laboratory markers measured were insulin resistance, tumor necrosis factor (TNF-α), type IV collagen and hyaluronic acid (HA). Results: Thirty patients were recruited, of whom 18 (60%) were men. Their mean age was 45 ± 13.9 (18-71) years. About 83% of patients had fibrosis stage 1-2. In bivariate analysis, age, TNF-α and type IV collagen concentrations showed a weak but significant correlation with the fibrosis stage. When the patients were grouped into mild fibrosis (stages 1-2) and advanced fibrosis (stages 3-4), the mean concentrations of HA and type IV collagen were significantly higher in those with advanced fibrosis than those with mild fibrosis (180.8 ± 49.63 vs 543.6 ± 360.45 ng/mL; for HA; P = 0.026 and 125.3 ± 32.11 vs 288.0 ± 171.22 ng/mL for type IV collagen; P = 0.010). Conclusion: Our study showed that the degree of liver fibrosis was significantly correlated with age, TNF-α and type IV collagen concentrations. The level of HA and type IV collagen could differentiate between mild (F1-2) and advanced fibrosis (F3-4).
