Core Tip
Core tip: Data presented in our study are based on a 7-year follow-up interval with systematic hemodynamic evaluations of more than 150 cirrhotic patients. We report for the first time a close relationship between osteopontin (OPN) and portal hypertension. Our findings suggest that OPN in plasma could be a marker of clinically significant portal hypertension. Importantly, we found that OPN is a strong prognostic indicator in patients with liver cirrhosis; and, similar to hepatic venous pressure gradient (HVPG) value, it significantly determined survival probability. Moreover, the combination of HVPG and OPN increased the validity of prognosis.
