Infection may cause liver diseases such as non-alcoholic fatty liver disease (9) and non-alcoholic steatohepatitis (10, 11), associated with inflammation and tissue damage (10, 12), particularly in individuals co-infected with hepatitis viruses (13) showing increased levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) (14). Here, GPT is linked to infection.
