SSA, Sjögren syndrome A; SSB, Sjörgen syndrome B.

Autoimmunity can damage nearly every tissue or cell type of the body. The spectrum, severity, and duration of disease vary widely. Depending on the organ systems involved, systemic and organ-specific autoimmune diseases have been delineated. Systemic autoimmune diseases include SLE, RA, scleroderma, Wegener's granulomatosis, Goodpasture syndrome, Sjogren's syndrome, der-matomyositis, psoriasis, ankylosing spondylitis, and inflammatory bowel diseases (Table 2).

Although SLE can involve almost any tissue of the body, inflammatory bowel diseases extend to fewer tissues, the gut, the joints, and the eye. Organ-specific diseases include insulin-dependent diabetes mellitus (IDDM), multiple sclerosis (MS), uveitis, thyroiditis, pernicious anemia, autoimmune hemolytic anemia, thrombocytopenia, hepatitis, primary biliary cirrhosis, pemphigus, pemphigoid, and vitiligo (Table 3). Individual patients may have more than one autoimmune disorder concurrently and subsequently.
