Background Assessment and quantification of actual liver function is crucial in patients with chronic liver disease to monitor disease progression and predict individual prognosis. Mathematical models, such as model for end-stage liver disease, are used for risk stratification of patients with chronic liver disease but do not include parameters that reflect the actual functional state of the liver.Aim We aimed to evaluate the potential of a C-13-based liver function test as a stratification tool by comparison with other liver function tests and clinical parameters in a large sample of healthy controls and cirrhotic patients.Methods We applied maximum liver function capacity (LiMAx) to evaluate actual liver function in 347 patients with cirrhosis and in 86 controls.Results LiMAx showed strong negative correlation with Child-Pugh Score (r = -0.707; p < 0.001), MELD (r = -0.686; p < 0.001) and liver function tests. LiMAx was lower in patients with liver cirrhosis compared to healthy controls [99 (57-160) mu g/kg/h vs. 412 (365-479) mu g/kg/h, p < 0.001] and differed among Child-Pugh classes [a: 181 (144-227) mu g/kg/h, b: 96 (62-132) mu g/kg/h and c: 52 (37-81) mu g/kg/h; p < 0.001]. When stratified patients according to disease severity, LiMAx results were not different between cirrhotic patients and cirrhotic patients with transjugular intrahepatic portosystemic shunt.Conclusions LiMAx appears to provide reliable information on remnant enzymatic liver function in chronic liver disease and allows graduation of disease severity.
