Abstract

Inflammatory markers as circulating soluble cellular adhesion molecules (sCAMs) and high sensitive C-reactive protein (hsCRP) are elevated in patients with chronic heart failure (CHF), and may constitute an increased risk of adverse outcome. Marine n-3 polyunsaturated fatty acids (n-3 PUFA) may have anti-inflammatory effect and reduce levels of sCAMs (soluble intercellular adhesion molecule-1 (sICAM-1), vascular adhesion molecule-1 (sVCAM-1), P-selectin) and hsCRP. In a randomized, controlled trial, 138 patients with NYHA class II-III CHF were allocated to receive a daily supplement of 0.9 g of n-3 PUFA or olive-oil for 24 weeks. After supplementation, no significant changes occurred in sCAMs or hsCRP after adjusting for possible confounders. However, a significant reduction was observed in sP-selectin in patients receiving n-3 PUFA, but this result was only of borderline significance in a between- group analysis. In conclusion, a daily supplement with 0.9 g of n-3 PUFA does not significantly affect plasma levels of sCAMs or hs-CRP in patients with CHF. n-3 PUFA may reduce sP-selectin, indicating a possible effect on platelet (and endothelial) activation. The results also indicate that the low dose of n-3 PUFA used in many intervention trials does not have deleterious effects on sCAMs or hsCRP.
