To make matters more confusing, the conjugated bilirubin is sometimes referred to as the direct-reacting bilirubin and the unconjugated as the indirect-reacting bilirubin (Table 3). 9!KAV v>D> The bilirubin that goes to your liver for processing is unconjugated, which means its not water-soluble (dissolvable in water).

Crigler-Najjar syndrome is a more severe variant of the same enzyme deficiency.13 Patients with impaired conjugation due to low levels of the bilirubin-UGT enzyme are particularly susceptible to jaundice from medications that inhibit this enzyme, such as protease inhibitors.6 Table 1 lists the causes of unconjugated hyperbilirubinemia.5,7,912, The largest worldwide contributor to liver disease is viral hepatitis, mostly from hepatitis C.14 Viral hepatitis causes increased oxidative stress within hepatocytes, leading to cell death, scarring, and diminished liver mass available for normal function.4,15 Chronic alcohol consumption can cause various hepatic disorders, including steatosis or fatty liver disease with minimal symptoms and often no jaundice; alcoholic hepatitis with acute onset jaundice and more severe symptoms; and cirrhosis, which is often associated with decompensation and liver failure in the setting of jaundice.3 Jaundice in persons with alcoholic liver disease can occur via multiple mechanisms, such as direct hepatocellular damage caused by ethanol metabolites or from alcohol's effect on bile acid uptake and secretion contributing to cholestasis.3,16, Approximately 30% to 40% of patients with nonalcoholic fatty liver disease progress to nonalcoholic steatohepatitis, and approximately 40% to 50% of these patients develop fibrosis or cirrhosis that may lead to hyperbilirubinemia.17 Although the exact mechanism is poorly understood, liver lipid deposition may trigger inflammation and fibrosis, particularly when coupled with type 2 diabetes.17 Sepsis may also induce hyperbilirubinemia as circulating acute phase reactants and bacterial endotoxins disrupt bilirubin transport, leading to cholestasis and elevated bile salt levels.18,19, Drug-induced liver injury has multiple potential mechanisms, including direct hepatocellular toxicity and activation of an immune response that advances the inflammatory cascade, inhibiting bilirubin transport into canaliculi, which causes cholestasis.20 Wilson disease, a rare genetic disorder, is associated with a loss of function of a cellular transporter responsible for moving dietary copper into liver canaliculi.
