What type of immune disorder is contact dermatitis?

Abstract. Allergic contact dermatitis is a Tcell mediated inflammatory skin disease that is caused by low molecular weight chemicals and metal ions. These contact allergens induce skin inflammation, an essential element of the sensitization process.

Is contact dermatitis an immune disorder?

For the first time, a team led by researchers at the Icahn School of Medicine at Mount Sinai has proven that atopic dermatitis, also known as eczema, is an immune-driven (autoimmune) disease.

What sort of immune reaction is contact dermatitis?

Allergic contact dermatitis is a classic example of a cell mediated hypersensitivity reaction in the skin. This occurs as a result of xenobiotic chemicals penetrating into the skin, chemically reacting with self proteins, eventually resulting in a hapten-specific immune response.

Is dermatitis an autoimmune disease?

Eczema is an umbrella term that describes various inflammatory skin conditions, or dermatitis. Several types of dermatitis involve an overreaction from the immune system, and some research suggests autoimmunity may play a role.

What diseases are considered autoimmune?

Examples of autoimmune diseases include:

  • Rheumatoid arthritis. …
  • Systemic lupus erythematosus (lupus). …
  • Inflammatory bowel disease (IBD). …
  • Multiple sclerosis (MS). …
  • Type 1 diabetes mellitus. …
  • Guillain-Barre syndrome. …
  • Chronic inflammatory demyelinating polyneuropathy. …
  • Psoriasis.

What is an autoimmune skin disease?

Autoimmune skin diseases occur because the body’s immune system attacks its own healthy tissues. The immune system would normally produce antibodies—proteins that react against bacteria, viruses, and toxins. When these antibodies attack healthy tissues, they are called autoantibodies.

Is contact dermatitis an inflammatory response?

Abstract. Allergic contact dermatitis is a Tcell mediated inflammatory skin disease that is caused by low molecular weight chemicals and metal ions. These contact allergens induce skin inflammation, an essential element of the sensitization process.

What type of hypersensitivity is irritant contact dermatitis?

Allergic contact dermatitis is an inflammatory disease of the skin that is caused by a type 4 hypersensitivity reaction.

What is the difference between irritant and allergic contact dermatitis?

Irritant contact dermatitis is caused by the non–immune-modulated irritation of the skin by a substance, leading to skin changes. Allergic contact dermatitis is a delayed hypersensitivity reaction in which a foreign substance comes into contact with the skin; skin changes occur after reexposure to the substance.
