Serum cytokeratin 18 (CK18-M65) as a surrogate marker of liver damage.
High serum CK18-M65 levels characterized progressive ALD (upper) and differentiate severe forms of alcoholic liver disease from the non-progressive forms of alcoholic liver disease, as shown by Receiver Operating Characteristic (ROC) analysis (middle) (AUROC = 0.8767; 95% CI: 0.7983–0.9551; p < .0001). Below, the cutoff identified using the Youden’s statistics (416.2 U/L) was characterized by high sensitivity and specificity (77.14% and 85.71%, respectively).
