Hyaluronic acid (HA) is an attractive potential marker for noninvasive diagnosis of liver fibrosis instead of liver biopsy for both patients and physicians. Aim: To assess the role of HA for diagnosing the progression of steatosis to steato-hepatitis (SH) and fibrosis in patients with Chronic Hepatitis C virus (HCV) infection. Methods: 90 patients with chronic HCV infection, 77 (85.6%) males and 13 (14.4%) females, were included. Blood samples were collected for routine laboratory

Results: Steatosis was found in 37 patients (41.1%), fibrosis in 29 patients (32.2%) and SH in 51 patients (56.7%). The mean serum HA for all patients was 86.4±48.2 ng/L. HA levels were significantly higher in patients with fibrosis (95.6±53 vs 54.5±3.5) and SH (88.7±52 vs 49.9±12) than those without (P value = 0.001and 0.001 respectively). HA levels were also significantly higher in patients with an advanced degree of fibrosis, SH and steatosis as compared to those with mild degrees (P value = 0.000, 0.001 and 0.01 respectively). Positive correlations were found between serum HA and the degree of fibrosis, SH and steatosis (P value =0.000 and r = + 0.758, 0.701and 0.727 respectively). The mean HA cut off value for the diagnosis of fibrosis and SH was taken to be 70 and 60 ng/L providing a diagnostic accuracy of 94.1% and 91.6% respectively. Conclusions: Serum HA level is a good noninvasive marker for the diagnosis of fibrosis and steato-hepatitis in patients with chronic HCV infection.
