We examined the effect of short-chain fatty acid-supplemented total parenteral nutrition on proinflammatory cytokine levels in piglets. Piglets (N = 22) received either standard total parenteral nutrition or total parenteral nutrition supplemented with short-chain fatty acids. After seven days of continuous nutrient infusion, proinflammatory cytokine (TNF-alpha, IL-1beta, IL-6) abundance in plasma, jejunal, and ileal samples and small intestinal myeloperoxidase was determined using western blotting. No differences were seen in TNF-alpha small intestinal abundance. IL-1beta was higher in the small intestine of the short-chain fatty acid group (P < 0.05). IL-6 was higher in intestinal samples of the short-chain fatty acid group (P = 0.05), with the ileum having a greater abundance of IL-6 than the jejunum (P < 0.005). No differences in proinflammatory cytokine abundance in the plasma or tissue myeloperoxidase were seen. These results indicate short-chain fatty acids beneficially increase small intestinal abundance of IL-1beta and IL-6 during total parenteral nutrition administration, while not affection systemic production of these cytokines or intestinal inflammation.
