Liver histology is the gold standard for diagnosis of non-alcoholic fatty liver disease. Ethical considerations and patient choice often preclude performing a liver biopsy, especially considering the rare but potential risk. Searching for a good serological marker substitute for the invasive procedure was the aim of our study. Keratins, mainly 8 and 18, play not only a mere structural role providing mechanical stability to hepatocytes, but also represent a target via toxic stress ultimately inducing apoptosis/necrosis. Tissue polypeptide-specific antigen (TPS), a serological mirror of keratin 18, is widely used as a marker for various cancers. This antigen was assessed in three different groups who were overweight or obese.
