Effects of dietary n-3 and n-6 fatty acids on clinical outcome in a porcine model on post-operative infection.


PMID 21810284

Abstract

The present study was performed to evaluate the effects of dietary n-3 and n-6 long-chain PUFA (LC-PUFA) on clinical outcome in a porcine model on early aortic vascular prosthetic graft infection (AVPGI). A total of eighty-four pigs were randomised to a 35xa0d dietary treatment with 10xa0% (w/w) fish oil (rich in n-3 LC-PUFA), sunflower oil (rich in n-6 LC-PUFA) or animal fat. After 3 weeks of dietary treatment, the pigs had an aortic vascular prosthetic graft inserted, and it was inoculated with Staphylococcus aureus (106 colony-forming units). Changes in selected plasma and erythrocyte n-3 and n-6 LC-PUFA concentrations and in plasma PGE2 metabolite concentration were determined in the 3-week preoperative period. Clinical signs of infection, i.e. rectal temperature, hindquarter function, general appearance and feed intake, were monitored daily in the 14xa0d post-operative period, and, finally, daily body-weight gain was determined in both periods. The preoperative changes in plasma and erythrocyte n-3 and n-6 LC-PUFA concentrations reflected the fatty acid compositions of the dietary treatments given, and plasma PGE2 metabolite concentration decreased in the fish oil treatment (Pxa0
