Eating More Fish – The Answer To Lupus?
11th March 2003
Press Release from the University of Ulster , Ireland
New research from the University of Ulster today offered hope to millions of lupus sufferers worldwide.
Dr Emeir Duffy, from the School of Biomedical Sciences, and Dr. Gary Meenagh, from Musgrave Park Hospital , have discovered new evidence to suggest that fish oil can greatly reduce the symptoms of the disease.
Systemic Lupus Erythematosus (SLE) or Lupus is a disorder of the Immune System, where the body harms its own healthy cells and tissues. The body tissues become damaged causing painful or swollen joints, unexplained fever, skin rashes, kidney problems, complications to the cardiovascular system and extreme fatigue.
There are approximately 500 diagnosed cases of SLE in Northern Ireland and it is most common in women of child-bearing age.
At present there is no cure but a key to managing lupus is to understand the disease and its impact. Steroids are the main drug used in the treatment of lupus and they should be administered for the shortest period possible to reduce side-effects.
But recently researchers have been looking specifically at its management through diet. Fish oils contain long-chained polyunsaturated fatty acids which are essential for normal growth and development but also have anti-inflammatory and anti-autoimmune properties.
Dr Duffy said: “We have been investigating how fish oil can improve the quality of life for lupus sufferers.
“In lupus, the body's immune system does not work as it should. Antibodies, which help fight viruses, bacteria and other foreign substances, are not produced effectively. The immune system actually produces antibodies against the body's own healthy cells and tissues. These auto-antibodies contribute to inflammation and other symptoms of the disease.
“Participants in the study who were taking fish oil supplements, three times per day for twenty-four weeks, saw a reduction in disease activity, an improvement in quality of life and reported an overall feeling of improved health by the end of the study compared to those taking a placebo supplement. Participants taking the fish oil also showed a reduction in fatigue severity, the most debilitating symptom for lupus sufferers.
“From our study and from other work, there is evidence that increasing dietary intake of the polyunsaturated fats found in fatty fish can have beneficial effects for lupus sufferers. Good examples of fatty fish include mackerel, lake trout, herring, sardines, tuna and salmon”.

New Research Shows Certain Vegetables May Delay the Onset and Reduce the Severity of Lupus
New Research Shows Certain Vegetables May Delay the Onset and Reduce the Severity of Lupus:
Scientists find that a compound abundant in broccoli, cauliflower and cabbage may help fight disease that affects 1.5 million Americans
A team of scientists from the North Shore-Long Island Jewish (LIJ) Research Institute have discovered that a compound found in abundance in the cruciferous family of vegetables delays the onset of systemic lupus erythematosus (SLE) in mice and reduces the severity of the disease once it has developed. This could be good news for individuals at risk for lupus, especially women, as well as those already affected by it.
Published today in the Journal of Nutrition, the study led by Karen Auborn, PhD, evaluated the effect of a supplement of indole-3-carbinol (I3C) - the compound found in broccoli, cauliflower, cabbage and similar vegetables - on the outcome of SLE in mice that are bred to develop the disease genetically. The results showed that mice with lupus lived significantly longer when fed the supplemented diet than did diseased mice fed the normal diet. Some even lived the normal lifespan.
Whether the mice were started on the I3C diet before or after the onset of the disease, the result was the same: there were fewer kidney problems (kidney disease is one of main complications of SLE) and they lived much longer than the control group.
"Mice are not people, of course, but the implication is that a diet rich in cruciferous vegetables could do much to ameliorate the disease," said Dr. Auborn. The findings support the view that I3C may benefit people at risk for SLE as well as those in the early stages of the disease. SLE is often treated with immunosuppressive drugs, which can have serious toxic side effects. By reducing the severity of the disease, I3C may allow a decrease in the dose of immunosuppressive drugs required, thereby reducing toxicity. It may even help prevent the recurrence of the disease.
A person could get the human equivalent dose of I3C tested in the study from about a third to a half of a head of cabbage. So getting the proper amount of I3C from food is realistic, although I3C also is available on the market as a dietary supplement.
According to the Lupus Foundation of America, approximately 1.5 million Americans suffer from some form of lupus, of which SLE is the most common. While it is unknown why women are nine times more likely to develop the disease than men, it is suspected that estrogen plays a role. Research has shown that women with SLE have abnormal estrogen metabolism. In many cancer prevention studies, I3C has been shown to exhibit antiestrogenic activity in the body. The North Shore-LIJ investigators had theorized that because I3C is an antiestrogen, it may prevent, delay, or even represent an adjunct treatment for lupus. They were right, at least for mice that genetically develop lupus.
The North Shore-LIJ Research Institute is planning a human study of the effects of I3C on SLE. Nicholas Chiorazzi, MD, a world-renowned rheumatologist and member of the study team, is working closely with Richard A. Furie, MD, chief of rheumatology at North Shore University Hospital in Manhasset, to make this a reality.
"It will be essential to determine if I3C can have similar effects in patients with SLE. Such studies are more difficult in humans because individual patients with lupus differ in their genetic backgrounds and also because the effects of lupus vary greatly from person to person, at least as far as the organs targeted by the problem," said Dr. Chiorazzi, who is also director and CEO of the North Shore-LIJ Research Institute.
This research was supported by grants from the Ryan Caulfield Foundation, the Willa and Robert Bernhard Fund, and the National Institutes of Health.
About the North Shore-Long Island Jewish Research Institute The North Shore-LIJ Research Institute is among the top seven percent of institutions nationally that receive funding from the National Institutes of Health. Building on its strengths in immunology and inflammation, oncology and cell biology, human genetics, and neurodegenerative and psychiatric disorders, its goal is to understand the biological processes that underlie various diseases and translate this knowledge into new tools for diagnosis and treatment.
