Autoimmune diseases arise from an overactive immune response of the body against substances and tissues normally present in the body. In other words, the body attacks its own cells. Autoimmune diseases are a major cause of immune-mediated diseases, and are commonly referred to as Autoimmune and Inflammatory Diseases (AIID).

Note to readers: as it stands this page appears to be muddled, repetitative and rather ill-informed. (For instance, the distinction between autoimmune and inflammatory disease is inconsistently applied and the classification of disorders includes a number of unsubstantiated claims.) The page on autoimmunity may be more helpful.

Gender influence

Nearly 79% of autoimmune disease patients in the USA are women. Also they tend to appear during or shortly after puberty. It is not known why this is the case, although hormone levels have been shown to affect the severity of some autoimmune diseases such as multiple sclerosis.[1] Other causes may include the presence of fetal cells in the maternal bloodstream. [2]

Autoimmune diseases

It is possible to classify autoimmune diseases by corresponding type of hypersensitivity: type II, type III, or type IV. (No type of autoimmune disease mimics type I hypersensitivity.)[3]

Development of therapies

In both autoimmune and inflammatory diseases the condition arises through aberrant reactions of the human adaptive or innate immune systems. In autoimmunity, the patient’s immune system is activated against the body's own proteins. In inflammatory diseases, it is the overreaction of the immune system, and its subsequent downstream signaling (TNF, INF, etc), which causes problems.

A substantial minority of the population suffers from these diseases, which are often chronic, debilitating, and life-threatening. There are more than eighty illnesses caused by autoimmunity. It has been estimated that autoimmune diseases are among the ten leading causes of death among women in all age groups up to 65 years.[28]

Currently, a considerable amount of research is being conducted into treatment of these conditions. According to a report from Frost & Sullivan, the total alliance payouts in the autoimmune/inflammation segment from 1997 to 2002 totaled $489.8 million, where Eli Lilly, Suntory, Procter & Gamble, Encysive, and Novartis together account for 98.6 percent of alliance payouts.[29]
