In a review in this issue, Clifton provides a survey of the oxy-lipids messengers (omega-6 eicosanoids) derived from arachidonic acid (C20: 4 omega-6) and possibilities for inhibition of their synthesis and actions by the long-chain omega-3 fatty acids eicosapentaenoic acid (C20: 5 omega-3, EPA) and docosahexaenoic acid (C22: 6 omega-3, DHA), which are present in fish oil. With regard to joint pain in arthritis, the omega-6 eicosanoid, prostaglandin E2 (PGE2), warrants explanatory emphasis. This mediator increases sensitivity to pain (nociception), which can arise from stretch and pressure during movement of arthritic joints. The analgesic effect of NSAIDs, also known as ‘cyclo-oxygense-2 inhibitors’, is attributed to reduced synthesis of PGE2. 4 PGE2 synthesis is inhibited by EPA and DHA in vitro with a similar potency to some NSAIDs. 5 Dietary fish oil rich in EPA and DHA has been shown to inhibit synthesis of PGE2 ex vivo, 6 as well as reduce synthesis of other inflammatory eicosanoids and cytokines. 3 In view of these metabolic effects, it is not surprising that medicinal use of fish oil, which is rich in EPA and DHA, has been shown to reduce symptoms and improve disease control in rheumatoid arthritis6 and systemic lupus. 7
