RESUMEN
<p><b>OBJECTIVE</b>To explore the levels of serum GP73 in patients with fatty liver disease.</p><p><b>METHODS</b>The sera GP73 were determined by ELISA in 178 patients with fatty liver disease and 100 healthy controls.</p><p><b>RESULTS</b>Serum GP73 levels were significantly increased in patients with various fatty liver diseases(70.62 +/- 60.60 ng/ml), compared with those of control population (35.61 +/- 12.22 ng/ml). In patients with alcoholic fatty liver disease, acute liver injury, chronic hepatitis B, and non-alcoholic fatty liver disease, their serum GP73 concentration were 81.86 +/- 47.82 ng/ml, 82.77 +/- 77.73 ng/ml, 63.84 +/- 50.62 ng/ml, and 65.75 +/- 62.20 ng/ml, respectively. But no significant difference was found between these groups (P > 0.05). In 68 patients with F > or = 1.0 (71.46 +/- 66.48 ng/ml), 75 patients with F> or = 2.0 (69.58 +/- 62.31 ng/ml), and 34 patients with F3-F4 (71.65 +/- 43.89 ng/ml), there were also no marked differences was observed between these fatty groups (F = 0.02, P = 0.98).</p><p><b>CONCLUSION</b>Serum GP73 levels were increased in patients with different liver diseases, but its concentrations were seems not related with degree of fatty injury.</p>
