He is fatigued constantly and has recently developed acute onset itching all over his body. The patient denies any allergies. Past medical history is significant for ulcerative colitis diagnosed 2 years ago, managed medically. He is vaccinated against hepatitis A and B and denies any recent travel abroad. There is scleral icterus present, and mild hepatosplenomegaly is noted. The remainder of the physical examination is unremarkable. Laboratory findings are significant for:Total bilirubin 3.4 mgdLProthrombin time 12 sAspartate transaminase AST 158 IULAlanine transaminase ALT 1161 IULAlkaline phosphatase 502 IULSerum albumin 3.1 gdLPerinuclear antineutrophil cytoplasmic antibodies p-ANCA positiveWhich of the following is the most likely diagnosis in this patient?? A: Hepatitis E, B: Primary sclerosing cholangitis, C: Hepatitis A, D: Primary biliary cirrhosis, E: Hepatitis B,  <response>: Based on the information provided in the question stem, the key findings are:- 35-year-old male with yellow discoloration of eyes and skin, right upper quadrant pain, fatigue, and itching for the past week - History of ulcerative colitis diagnosed 2 years ago- Vaccinated against hepatitis A and B- Physical exam shows scleral icterus and hepatosplenomegaly- Lab findings show elevated total bilirubin, AST, ALT, alkaline phosphatase, and positive p-ANCAThe elevated bilirubin, transaminases, and alkaline phosphatase indicate liver injury and cholestasis. The timeline of symptoms over the past week points towards an acute process rather than chronic liver disease. The positive p-ANCA is associated with autoimmune conditions like ulcerative colitis. Therefore, the most likely diagnosis is autoimmune hepatitis triggered by the patients underlying ulcerative colitis.B: Primary sclerosing cholangitis
