Objective: Soluble receptor activator of nuclear factor-kappa B ligand (sRANKL) to osteoprotegerin ratio is designated as a bone metabolism equation in many rheumatologic disorders and would be modified with Fish Oil (FO) supplementation. Design and Methods: Eighty three females with rheumatoid arthritis were divided randomly to 40 and 43 patients treated with (1g/day) or without FO for 3 months accompanied with conventional drugs, respectively. Osteoprotegerin, sRANKL, tumor necrosis factor alpha (TNFalpha) serum levels were measured before and after treatment. Results: Serum levels of osteoprotegerin increased, although sRANKL, TNFalpha and sRANKL/osteoprotegerin ratio decreased with FO therapy. A significant positive correlation was observed between sRANKL/osteoprotegerin ratio and TNFalpha levels (r = 0.327, p = 0.040) in the FO treated group. Conclusions: FO could decrease the inflammatory response by lowering of serum TNFalpha levels and sRANKL/osteoprotegerin ratio. Copyright © 2009. Published by Elsevier Inc.
