Current status of lipid emulsions in the prevention of intestinal failure-associated liver disease.

PURPOSE OF REVIEW

The current review provides a summary of available lipid products and discusses current literature and the limitations to the use of various lipid products for treatment and prevention of intestinal failure-associated liver disease (IFALD) in pediatric patients dependent on parenteral nutrition.

RECENT FINDINGS

Improvements in markers of cholestasis and liver function have been seen with minimizing soybean lipid, fish oil lipid, and mixed fish oil-containing lipid emulsions. Soybean-based lipid products are thought to be the biggest contributor to development of IFALD. Mixed fish oil-containing lipid emulsions are most promising for minimizing and improving IFALD.

SUMMARY

Several types of lipid-based products are available for parenteral nutrition. Newer products like the mixed fish oil-containing-based lipid emulsions, that closely mimic the lipid composition provided by enteral feeding, may impact prevention and treatment of IFALD. Limitations exist in the current literature regarding mixed fish oil-containing-based emulsions, as many of the studies were designed to show efficacy with regard to growth, not prevention or treatment of IFALD. Based on available literature, it is reasonable to make some recommendations with regard to product selection for lipid provision.
