Background and aims
Omega-3 fatty acids (FA) can ameliorate the hyper-inflammatory response that occurs in conditions such as severe acute pancreatitis (SAP) and this may improve clinical outcome. We tested the hypothesis that parenteral omega-3 FA from a lipid emulsion that includes fish oil could be beneficial in patients with predicted SAP by reducing C-reactive protein (CRP) concentration (primary outcome), and modulating the inflammatory response and improving clinical outcome (secondary outcomes).

In a phase II randomized double‐blind single-centre controlled trial, patients with predicted SAP were randomised to receive a daily infusion of fish oil containing lipid emulsion (Lipidem® 20%, BBraun) for 7 days (n=23) or a daily infusion of a lipid emulsion without fish oil (Lipofundin® MCT 20%, BBraun) (n=22).

On admission, both groups had comparable pancreatitis predicted severity and APACHE II scores. Administration of fish oil resulted in

  • lower total blood leukocyte number (P=0.04), CRP (P=0.013),
  • interleukin-8 (P=0.05) and
  • intercellular adhesion molecule 1 (P=0.01) concentrations,
  • multiple organ dysfunction score,
  • sequential organ failure assessment score (P=0.004),
  • early warning score (P=0.01), and
  • systemic inflammatory response syndrome (P=0.03)

compared to the control group.
The fish oil group had

  • fewer new organ failures (P=0.07),
  • lower critical care admission rate (P=0.06).,
  • shorter critical care stay (P=0.03) and
  • shorter total hospital stay (P=0.04).

It is concluded that intravenous administration of a fish oil containing lipid emulsion, a source of omega-3 FA, improves clinical outcomes in patients with predicted SAP, benefits that may be linked to reduced inflammation.
