After six weeks of therapy, he developed signs of drug-induced hepatotoxicity, with cytolysis evidenced by aspartate aminotransferase (AST) at 208.3 U/L (≈4.6× normal) and alanine aminotransferase (ALT) at 254.8 U/L (≈5.6× normal), as well as cholestasis with alkaline phosphatase (ALP) at 628.1 U/L (≈5× normal) and gamma-glutamyl transferase (GGT) at 667.2 U/L (≈14.8× normal). Here, GPT is linked to cholestasis.
