Title: Serum fetuin A/α2HS-glycoprotein levels in patients with non-alcoholic fatty liver disease: relation with liver fibrosis.
Abstract: BACKGROUND: Serum concentrations of fetuin A/&#945;2HS-glycoprotein (AHSG) have been linked to human metabolic alterations and can serve as an indicator of liver cell function. We assayed serum levels of AHSG in patients with non-alcoholic fatty liver disease (NAFLD), a hepatic manifestation of the metabolic syndrome, and examined their association with clinical, biochemical and histological phenotypes. METHODS: Serum AHSG levels were determined by enzyme linked immunosorbent assay in 99 patients with biopsy-proven NAFLD and 75 age- and gender-matched controls. RESULTS: Serum AHSG levels were significantly higher in patients with NAFLD (940 &#177; 120 &#956;g/mL) compared with healthy controls (800 &#177; 130 &#956;g/mL, Student's t test, P < 0.001). Bivariate analyses (Spearman's rank correlation) in patients with NAFLD showed a statistically significant association between AHSG levels and insulin resistance as assessed by the HOMA (homeostasis model assessment) index (r = 0.31, P < 0.01) and the liver fibrosis score index (r = 0.36, P < 0.001). The association between AHSG and fibrosis remained statistically significant even after adjustment for potential confounders, including the HOMA index ([beta] = 1.65, t = 2.38, P < 0.05). CONCLUSION: Serum AHSG levels are significantly increased in adult patients with biopsy-proven NAFLD and are associated with insulin resistance. Importantly, our pilot data indicate that serum AHSG levels may identify NAFLD patients with higher fibrosis scores.
