Bilirubin is a biomarker for the diagnosis of liver diseases or bile duct dysfunction. This study assessed the physiological changes in the blood bilirubin level infusing ω-3 enriched parenteral nutrition (PN) and ω-3 free PN in healthy male subjects.
This study was a randomized, open-label, two-treatment, two-way crossover trial. Sixteen subjects were assigned randomly to one of two sequences of the two treatments: ω-3 enriched PN or ω-3 free PN was infused via aperipheral venous catheter for six hours at 3 mL/kg/h. Blood samples were collected every one hour from 0 to 12 hours after starting an intravenous infusion for bilirubin concentrations. The total bilirubin and direct bilirubin concentrations in the blood were analyzed using an enzymatic method.
The bilirubin concentration in the blood was reduced while infusing the ω-3 enriched PN and ω-3 free PN. When it stopped infusing, the bilirubin concentration was recovered. A similar pattern was observed, but there was a further decline and recovery in ω-3 free PN.
When ω-3 enriched PN and ω-3 free PN are infused in healthy male subjects, the blood bilirubin level decreasedand there is no difference between the two groups.
