Immune Modulation by Parenteral Lipids

Status Completed

Clinical Trial Summary

Immune modulating properties of parenteral lipid emulsions seem to contribute to the increased risk for infections which remains associated with the use of total parenteral nutrition. Emulsions based on soy bean oil (SO) are the oldest and still most widely used lipid source in TPN formulations but their high content of omega-6 polyunsaturated fatty acids (PUFAs) may be a drawback. Fish oil-based lipid emulsions (FO), rich in omega-3 PUFAs, has been approved for parenteral nutrition in many countries. Mainly retrospective studies on clinical outcomes in septic and postoperative patients have suggested clinical benefits with the inclusion of FO in parenteral nutrition regimens. The exact mechanisms behind the beneficial immunological effects of parenteral FO have, however, not yet been elucidated.

Objective:

To evaluate the effects of intravenous infusion of a FO-based lipid emulsion and a SO-based emulsion on immune function as evidenced by effects on peripheral blood leukocyte counts and functions and on the susceptibility to oxidative stress.

Study design:

Randomized placebo controlled cross-over pilot study with healthy volunteers.
