Many doctors now agree that omega-3 fatty acids (typically found in fish oil or flaxseed oil) can help reduce eye dryness associated with Sjogren's Syndrome. But can they do more? Omega-3s are often referred to as having anti-inflammatory properties, which makes many people who have autoiummune conditions like Sjogren's Syndrome wonder if omega-3s can reduce the "inflammation" behind autoimmune diseases.
Research has been spotty at best (a literature review from the Agency for Healthcare Research and Quality done in 2004 showed mixed or no results for use of omega-3s to treat rheumatoid arthritis, systemic lupus erythematosus, and inflammatory bowel disease), although the medical field is finally catching up to this idea. For example, Dr. Michelle Petri, a lupus specialist at Johns Hopkins University, is about to begin a clinical trial asessing the efficacy of fish oil in lupus patients; and the National Center for Complementary and Alternative Medicine is currently running a study focusing on fish oil and borage oil in treatment of rheumatoid arthritis. However, I know many autoimmune patients who aren't waiting for research to confirm that omega-3s help reduce symptoms... they are on fish oil or flaxseed oil already.
I have considered fish oil or flaxseed oil for my eyes, and wondered about whether it would do anything for my Sjogren's. I tried fish oil pills briefly, but the nasty fish burps afterwards really turned me off. When my allergist recently told me there is anecdotal evidence that fish oil helps alleviate the symptoms of exercise-induced asthma, I decided it might be time to try it again.
I consulted with my rheumatologist about whether omega-3s might help my Sjogren's, and if so, what the proper dose would be. She referred me to a study in the Annals of the Rheumatic Diseases 2008;67:841–848 showing that low-dose omega-3s have beneficial effects on disease activity in patients with SLE and help protect them against the atherosclerosis typical in lupus patients. You can read a project abstract in PubMed, here: "A randomised interventional trial of omega-3- polyunsaturated fatty acids on endothelial function and disease activity in systemic lupus erythematosus". Of course, there is no comparable study for Sjogren's patients yet.
The magic dose in the study was 1.8 g eicosapentanoic acid (EPA) and 1.2 g docosahexanoic acid (DHA) per day. Now I need to run to the store and see if I can get that more easily in pill form or liquid form. My initial research shows that you have to take a lot of pills each day to reach those totals. I'm hoping fish oil in liquid form will provide a more concentrated dose. A fair warning: the study showed that lower doses were not as effective in reducing the "oxidative stress" that contributes to heart and vascular disease in lupus patients.
