Liver disease in children occurs via a multitude of primary illnesses such as autoimmune hepatopathy, biliary atresia, and nonalcoholic fatty liver disease. However, jaundice, hepatitis, and alterations in liver tests can often be a manifestation of systemic diseases. The liver is involved in many critical functions such as circulation, immunity, toxin clearance, and metabolism; when the heart, lungs, gastrointestinal tract, immune system, or endocrine systems are compromised, the liver will be affected. This article reviews common causes of liver injury as well as highlights key associations that should not be missed when diagnosing and managing children with liver disease. Becoming familiar with patterns of liver injury and arranging clues in the context of a thorough history and physical examination can help providers navigate the broad differential diagnosis of secondary liver disease.
