Long-Term Use of Mixed-Oil Lipid Emulsion in Soybean Oil-Intolerant Home Parenteral Nutrition Patients.

BACKGROUND: Although home parenteral nutrition (HPN) is lifesaving for patients with chronic intestinal failure (IF), long-term use can be associated with complications such as infections, metabolic abnormalities, and IF-associated liver disease (IFALD). The key to treatment of many of these complications is prevention. Guidelines recommend avoidance of overfeeding, use of oral/enteral nutrition if possible, cyclic PN, and maintaining dose of soybean oil (SO) intravenous lipid emulsion (ILE) <1 g/kg/day as preventive strategies for IFALD. Additionally, with development of IFALD, ω-6/ω-3 polyunsaturated fatty acid ratio should be decreased in ILE. The newly available mixed-oil (MO) ILE offers such an opportunity; however, there is a paucity of long-term data available.

METHODS: The current study reports our long-term experience with MO ILE use in HPN patients.

RESULTS: Seventeen patients (8 female and 9 male) with an average age of 47 ± 12 years and median HPN duration of 4.6 years (1.1-32.1 years) have utilized MO ILE for >12 months after being transitioned from SO ILE because of intolerance. Use of MO ILE allowed an increase in ILE energy from 8% ± 8% to 22% ± 8% while reducing dextrose energy from 66% ± 8% to 54% ± 5%, maintaining stability in alkaline phosphatase and triglyceride levels, and achieving improvement in aspartate aminotransferase, alanine aminotransferase, total bilirubin, and α-tocopherol levels.

CONCLUSION: In this HPN cohort with SO ILE intolerance, MO ILE was well tolerated and allowed an improvement in macronutrient composition while improving some liver parameters over a 12-month period.
