Sjogren syndrome is an autoimmune condition characterized by dry eye and dry mouth. A recent medical journal article suggests that Sjogren “disease” should be defined by the presence of specific anti-Ro/La antibodies, while Sjogren “syndrome” has similar symptoms without these antibodies. Other authors report progress in diagnosis and treatment.
Biopsy of the salivary gland has been commonly used as a diagnostic tool. However, an article from the University of Chicago reports that biopsy is usually not necessary. A Japanese research team reports that ultrasound imaging is an effective diagnostic tool. It has the advantages that it is non-invasive and easy to use.
Treatment includes anti-inflammatory and immune-modulating drugs. A review article in the Journal of the American Medical Association has this to say about the most commonly used drugs:
1. Pilocarpine and cevimeline (Evoxac) are beneficial, based on evidence from controlled trials.
2. Cyclosporine eye drops are beneficial for dry eye.
3. Anti-tumor necrosis factor drugs have not shown clinical efficacy for Sjogren syndrome. These drugs include infliximab (Remicade) and etanercept (Enbrel). This is important because these drugs have serious side effects, must be administered by injection, and are expensive.
4. Rituximab demonstrated significant results in some secondary outcomes in two small trials. Larger controlled trials are suggested for this drug. It is also an expensive option with serious side effects, and must be injected.
I reported last year on clinical trials for dietary supplements being tested for Sjogren's syndrome. I found two: DHEA and EPA (and omega-3 fatty acid). The DHEA studies are now reported as complete, and the EPA study terminated with the data being analyzed. I hope to see results published soon. Other clinical trials are in progress for a variety of drug options, as well as mesenchymal stem cell transplants.

I was just recently diagnosed with Sjogrens. I seem to have a lot of pain in my back and legs. Very tired, and should not be. And I have a difficult time concentrating at times. I has become very hard to me to work. Stairs are a threat to me as it is so painful going up and down.

I look forward to any updates on Sjogren's Syndrome. I was diagnosed at age 50 and am now 64. I have learned to be so very 'tuned in' to my body as it is just not dry eye and dry mouth. It is systemic so the whole body is effected by it. Some days are very frustrating....and all I want is my life back.
February 5, 2011 - 11:20amWould love to hear back from other SS patients and how they deal with it.
