Effect of Parenteral Nutrition With n-3 PUFAs on Patients With Intestinal Failure

Randomized, double-blind, controlled clinical trial to evaluate the effect of parenteral nutrition (PN) supplemented with lipid emulsions containing 0.1-0.2 g omega 3 polyunsaturated fatty acids (n-3 PUFA)/kg body weight/day for 7 days on malondialdehyde (MDA) levels, a marker of lipoperoxidation of reactive species, compared with a control group (without n-3 PUFA) in patients with intestinal failure (IF).

About this study

IF is the loss of intestinal function that affects the decrease in the absorption of macronutrients, water, and electrolytes, so it requires intravenous supplementation such as PN and/or intravenous fluids to maintain health and/or growth. IF type II is associated with complex infectious and metabolic complications and patients require PN for weeks or months. Long-term PN use, however, includes the risk of complications, among which a serious one is the intestinal failure-associated liver disease (1). It has been proposed that metabolic endotoxemia (2-3), inflammation (4) and oxidative stress (5) are involved in the development of this intestinal failure-associated liver disease.

Although some studies have reported beneficial effects of n-3 PUFA to prevent and reverse the liver disease associated with IF (6-7), due to its antioxidant (8-10) and anti-inflammatory activity (11-12) and in the modulation of the intestinal microbiota (13), the literature on the use of n-3 PUFA in non-critical patients with IF and PN is limited and the results have not been conclusive.

Therefore, a randomized, double-blind, controlled clinical trial to evaluate the effect of PN supplemented with lipid emulsions containing n-3 PUFA/kg body weight/day for 7 days on oxidative stress (concentrations of MDA), compared with a control group (without n-3 PUFA) will be performed.
