What is Lucey-Driscoll syndrome?

• A. A rare form of jaundice caused by unconjugated bilirubin
• B. An inherited disorder affecting bilirubin metabolism
• C. A common form of liver disease in newborns
• D. An autoimmune condition leading to jaundice

Answer: (A)

Lucey-Driscoll syndrome is indeed characterized as a rare form of jaundice specifically caused by the accumulation of unconjugated bilirubin. This condition arises due to an immature ability of the liver to process bilirubin in infants, leading to elevated levels of unconjugated (indirect) bilirubin in the bloodstream. In this syndrome, the liver does not adequately conjugate bilirubin, which is typically necessary for it to be excreted from the body. The result is a distinctive form of jaundice that presents in newborns, often shortly after birth. Understanding this mechanism is crucial, as it underlines the pathophysiology behind the clinical presentation. The other options mentioned, while related to jaundice or liver function, do not accurately define Lucey-Driscoll syndrome. For instance, an inherited disorder affecting bilirubin metabolism generally refers to conditions like Gilbert's syndrome or Crigler-Najjar syndrome, rather than Lucey-Driscoll. Additionally, it is important to note that Lucey-Driscoll syndrome is not categorized as a common form of liver disease in newborns; rather, it is less prevalent and primarily associated with the specific issue of unconjugated bilirubin
