Direct/Conjugated Hyperbilirubinemia as an Uncommon Presentation of Acute Alcoholic Hepatitis: A Case Report.

Alcoholic liver disease (ALD) is a common pathology in clinical practice and is clinically diverse. Acute alcoholic hepatitis is an acute inflammation of the liver with or without underlying cholestasis and steatosis. In this case, we are presenting a 36-year-old male with a past medical history of alcohol use disorder who presented with two weeks of right upper quadrant abdominal pain and jaundice. However, direct/conjugated hyperbilirubinemia with relatively low aminotransferases in labs prompted investigation for obstructive and autoimmune hepatic pathologies. Unrevealing investigations prompted consideration of acute alcoholic hepatitis with cholestasis and a course of oral corticosteroids that gradually improved the patient's clinical symptoms and liver function test. This case helps to remind clinicians that although ALD is usually associated with indirect/unconjugated hyperbilirubinemia and elevated aminotransferases, presentation of ALD with mainly direct/conjugated hyperbilirubinemia with relatively low aminotransferases is a possibility. Although imaging tests should be pursued to rule out obstructive etiologies, invasive tests and liver biopsies are not indicated in typical clinical settings.
