Antibiotic Protocol of Dr. Brown is worth looking at because all autoimmune illnesses are caused by Increased Digestive Permeability aka "Leaky Gut" and it is infection by a microorganism in the stomach which causes it. That coupled with changes in the nervous system which affects immune system regulation which dictates which areas are affected by the circulating antibody complexes. Areas where immune system regulation is weak will provoke immune system reactions. BTW the nervous system changes can be corrected but it can take some time. Destroying the infection would be much faster but I would not use pharmaceutical Antibiotics because they might affect other areas of the digestive system.
