What is the current understanding of choline's role in PN-related liver disease?

• A. Choline completely prevents PN-associated liver disease
• B. Choline has no role in PN management
• C. There is evidence of steatosis resolution with choline; more studies are needed to evaluate PN-associated liver disease
• D. Choline worsens PN liver disease

Answer: (C)

Choline acts as a lipotropic nutrient that enables the liver to export fat in the form of VLDL, preventing fat accumulation in hepatic cells. In patients receiving parenteral nutrition, inadequate choline intake can contribute to hepatic steatosis, so supplementation has been studied as a way to address PN-related liver changes. The best-supported finding so far is that adding choline to PN can lead to resolution or improvement of hepatic steatosis in some patients. However, PN-related liver disease is multifactorial, and current evidence is not enough to say choline prevents or cures all aspects of PN-associated liver disease; more research is needed. Therefore, the correct understanding is that there is evidence of steatosis resolution with choline, but further studies are needed to fully evaluate its impact on PN-associated liver disease.
