<<Disclaimer: Verify this information before applying it to your situation.>> Dear Listmates: If one molecule of gluten is damaging why is it that they are using low gluten hosts over in Ireland and this is allowed for celiacs over there? I was taking 1/4 of a low gluten host and I am sure hidden gluten and now I have dermatomyositis after being on the gluten free diet for almost seven years. If any celiacs are experiencing muscle weakness you should get checked for this because it is autoimmune and attacks your muscles. The apparent immune system gene predisposing to juvenile and familial dermatomyositis is the HLA-DQA1*0501 gene. This is part of the celiac gene. The organization for myositis is www.myositis.org Here is more research information that I found. Research shows that people with autoimmune disease have the same chance of being gluten sensitive as family members of celiacs and that is 78%. People who test without either of these risk factors have a 48% of gluten sensitivity, high, but a lot lower than autoimmune states. Everyone should be tested for gluten sensitivity celiac disease. You can now test for gluten sensitivity with Dr. Fine's new stool test at www.enterolab.com Gluten sensitivity appears to be the trigger for most autoimmune diseases. This is why children over in Italy are being screened at age 7. The Italians have well known this. Hope this information will help someone. Elaine
