Previous studies have shown that the treatment outcomes of chronic hepatitis C are associated with the genotype, HCV RNA viral load, age, sex, BMI, metabolic syndrome, insulin resistance, alcohol consumption, and liver disease characteristics, including ALT and gamma-glutamyl transferase levels, fibrosis stage, and co-infection with another hepatotropic virus or HIV [22, 29, 30, 39]. This evidence concerns the gene GPT and liver disorder.
