Definitions:
* group of >80 serious, chronic illnesses
* underlying problem is the samefor all
* immune system is misdirected
* body attacking its own self
* 4th largest cause of disability (Europe & the US)
*
Demonstration of: * immunoglobulins * autoantibodies * cytotoxic T * cells * self antigens * auto-antigens
1.persistent activation of immunologic effector mechanisms
2.that change the function and integrity of cells and organs
3.sites of organ / tissue damage depend on the location of the immune reaction
Examples: ClinicalDiagnosis | Autoantigen | Addison’s Disease | p-450 | Crohn’s Disease | p-ANCA, pancreatic acinar cells | Ovarian Failure / Infertility | p-450 | Pernicious Anemia | Parietal cells | Ulcerative Colitis | p-ANCA |

Classification
Organ-specific * both lesions & autoAb’s confined to 1 organ
Midspectrum
* localized lesions in an organ
Organ non-specific * autoAb’s organ non-specific both lesions & autoAb’s NOT confined to 1 organ
Organ-specific disorders
• Thyroid
• Hashimoto’s thyroiditis
• Primary myxedema
• Thyrotoxicosis
• Stomach
• Pernicious anemia
• Adrenal
• Addison’s disease
• Pancreas
• Juvenile diabetes
Organ-nonspecific disorders
• Muscle
• Dermatomyositis
• Kidney
• SLE
• Skin
• Scleroderma
• Joints
• Rheumatoid arthritis
Specific vs. Non-Specific (Similarities)
1. Circulating autoantibodies react with normal body constituents.
2. Increased Ig concentration in serum often found.
3.
