Examples of autoimmune diseases in the following topics:
-
- Autoimmune diseases are an inappropriate immune response against tissues in the body.
- Autoimmune diseases are commonly considered complex immune disorders.
- While many autoimmune diseases are rare, collectively these diseases afflict millions of patients.
- However, defects of one or more of these genes do not cause an autoimmune disease, but only predispose a person for an autoimmune disease.
- The factors that trigger an autoimmune disease are still unknown.
-
- Any disease that results from such an aberrant immune response is termed an autoimmune disease.
- Autoimmune diseases are very often treated with steroids.
- Three main sets of genes are suspected in many autoimmune diseases.
- A person's sex also seems to have some role in the development of autoimmunity, classifying most autoimmune diseases as sex-related diseases.
- Define autoimmunity and explain how it gives rise to autoimmune disease
-
- Any disease that results from such an aberrant immune response is termed an autoimmune disease.
- Autoimmune diseases are very often treated with steroids.
- Genetically predisposed individuals do not always develop autoimmune diseases.
- A person's sex also seems to have some role in the development of autoimmunity, classifying most autoimmune diseases as sex-related diseases.
- According to the American Autoimmune Related Diseases Association (AARDA), autoimmune diseases that develop in men tend to be more severe.
-
- In autoimmune heart diseases, the body's immune defense system mistakes its own cardiac antigens as foreign, and attacks them.
- Autoimmune heart diseases result when the body's own immune defense system mistakes cardiac antigens as foreign, and attacks them, leading to inflammation of the heart as a whole, or in parts.
- The most common form of autoimmune heart disease is rheumatic heart disease, or rheumatic fever.
- A typical mechanism of autoimmunity is autoantibodies, or auto-toxic T-lymphocyte mediated tissue destruction.
- Aetiologically, autoimmune heart disease is most commonly seen in children with a history of sore throat caused by a streptococcal infection.
-
- Systemic lupus erythematosus (SLE) is an autoimmune disease that can occur in any organ or tissue in the body.
- Systemic lupus erythematosus, often abbreviated to SLE or lupus, is a systemic autoimmune disease (or autoimmune connective tissue disease) that can affect any part of the body.
- As with other autoimmune diseases, the immune system attacks the body's own cells and tissue, resulting in inflammation and tissue damage.
- The course of the disease is unpredictable, with periods of illness (called flares) alternating with remissions.
- It is the prototypical autoimmune disease.
-
- Ankylosing spondylitis is a chronic inflammatory, autoimmune disease that results in joint fusion in the vertebrae and the sacroiliac joint.
- AS is a form of spondyloarthritis, a chronic, inflammatory arthritis and autoimmune disease.
- However, only 5% of individuals with the HLA-B27 genotype contract the disease
- Symptoms of the disease first appear, on average, at age 23 years.
- Men are affected more than women by a ratio of about 3:1, with the disease usually taking a more severe course in men than women.
-
- Several mechanisms are thought to be operative in the pathogenesis of autoimmune diseases, against a backdrop of genetic predisposition and environmental modulation.
- A feature of human autoimmune disease is that it is largely restricted to a small group of antigens, several of which have known signaling roles in the immune response (for example DNA, C1q, IgGFc, Ro, Con.
- When tolerance to self proteins is lost, DQ may become involved in autoimmune disease.
- Two autoimmune diseases in which HLA-DQ is involved are celiac disease and diabetes mellitus type 1.
- Define cell-mediated autoimmunity and describe the mechanisms that are thought to operate in the pathogenesis of autoimmune disease
-
- Addison's disease and congenital adrenal hyperplasia can manifest as adrenal insufficiency.
- One subtype is called idiopathic or unknown cause of adrenal insufficiency. 80% are due to an autoimmune disease called Addison's disease or autoimmune adrenalitis.
- Tertiary adrenal insufficiency is due to hypothalamic disease and decrease in corticotropin releasing factor (CRF).
- For chronic adrenal insufficiency, the major contributors are autoimmune adrenalitis, tuberculosis, AIDS, and metastatic disease.
- Autoimmune adrenalitis may be part of Type 2 autoimmune polyglandular syndrome, (which can include type 1 diabetes), hyperthyroidism, autoimmune thyroid disease (also known as autoimmune thyroiditis and Hashimoto's disease).
-
- The types of hypersensitivities include immediate, delayed, and autoimmunity hypersensitivities.
- Most types of autoimmunity involve the humoral immune response.
- In patients with the autoimmune disease myasthenia gravis, muscle cell receptors that induce contraction in response to acetylcholine are targeted by antibodies.
- In systemic lupus erythematosus, a diffuse autoantibody response to the individual's own DNA and proteins results in various systemic diseases.
- Autoimmunity can develop with time; its causes may be rooted in molecular mimicry.
-
- A hypersensitivity reaction refers to an overreactive immune system triggered by allergies and autoimmunity.
- Hypersensitivity (also called hypersensitivity reaction) refers to undesirable reactions produced by the normal immune system, including allergies and autoimmunity, and are commonly mediated by antibodies.

- Associated disorders: Contact dermatitis, Mantoux test, Chronic transplant rejection, Multiple sclerosis, T-cells VAutoimmune disease receptor mediated, Graves' disease,Myasthenia Gravis.
