My sons ALT and AST levels have continued to rise since the first 6-8 weeks on the med. The hep test in the beginning was neg. Now with continued high levels an ANA was ran and high. The GI mention autoimmune hepatitis and a liver biopsy. My son also never had acne but since the med has had it out of control. In all my research others GI had them stop med within 3 consecutive high results. I am frustrated by the GI mentioning a liver biopsy but not finding an alterative option for Crohn's treatment.:ybatty: Thoughts? Anybody have similar issues? What was the solution? Thanks
