What is true about choline in PN-related liver dysfunction based on current evidence?

• A. Injectable choline is standard and proven to improve outcomes
• B. There is no commercially available injectable choline and benefits are unproven
• C. Choline supplementation is contraindicated
• D. Choline is routinely given in PN solutions

Answer: (B)

Choline's importance in PN-related liver dysfunction lies in its role as a component of phosphatidylcholine, which is essential for assembling VLDL particles and exporting fat from the liver. While this provides a biological rationale for choline supplementation, current evidence does not show that injectable choline improves liver outcomes, and there is no commercially available injectable choline product. Because of that, choline is not considered a proven or standard intervention for PN-associated liver issues, and routine use in PN solutions for this purpose is not established. A and D imply routine, proven benefit which isn’t supported, while C would suggest contraindication, which isn’t the current stance.
