Atopic Dermatitis


Atopic dermatitis (AD) is an inflammatory, chronically relapsing, non-contagious and pruritic (that is, itchy) skin disorder. The skin of a patient with atopic dermatitis reacts abnormally and easily to irritants, food, and environmental allergens and becomes red, flaky and very itchy. It also becomes vulnerable to surface infections caused by bacteria. The skin on the flexural surfaces of the joints (for example inner sides of elbows and knees) are the most commonly affected regions in people.

Although atopic dermatitis can theoretically affect any part of the body, it tends to be more frequent on the hands and feet, on the ankles, wrists, face, neck and upper chest. Atopic dermatitis can also affect the skin around the eyes, including the eyelids.

Optional Causes:

  • Epidermal Barrier Dysfunction

    More recently, a theory involving the role of Epidermal Barrier Dysfunction has been proposed as an explanation on the physiopathology of atopic dermatitis. Changes in at least 3 groups of genes encoding structural proteins, epidermal proteases and protease inhibitors predispose to a defective epidermal barrier and increase the risk of developing atopic dermatitis.


  • Allergy

    Although it is an inherited disease, eczema is primarily aggravated by contact with or intake of allergens.


  • Microwave radiation

    Exposure to microwave radiation from a cell phone can worsen existing allergies to house dust mite and Japanese Cryptomeria pollen.


  • Food allergy

    While no cause of atopic dermatitis, food allergy is often present in atopic children, and children with food allergy often present with skin dermatitis indistinguishable from atopic dermatitis.


  • Histamine intolerance

    A subset of people afflicted with atopic dermatitis are affected by exogenous sources of histamine. About one-third (33%) of atopic eczematics significantly improve their symptoms after following a histamine-free diet.

Treatment Options:

Maintaining the skin barrier

The primary treatment involves prevention, includes avoiding or minimizing contact with (or intake of) known allergens. Once that has been established, topical treatments can be used. Topical treatments focus on reducing both the dryness and inflammation of the skin. Atopic dermatitis has also been linked to a ceramide deficiency. Ceramide is one of the three key lipids that comprise the skin barrier. There are various ceramide based creams available including the prescription drug Epiceram as well as other non-prescription options like Cerave and Aveeno for Eczema.


If moisturizers on their own don't help and the eczema is severe, a doctor may prescribe topical corticosteroid ointments, creams, or injections. Corticosteroids have traditionally been considered the most effective method of treating severe eczema. Disadvantages of using steroid creams include stretch marks and thinning of the skin.


Light (UV) therapy

A more novel form of treatment involves exposure to broad or narrow-band ultraviolet light. UV radiation exposure has been found to have a localized immunomodulatory effect on affected tissues and may be used to decrease the severity and frequency of flares.


Light Therapy Systems


XTRAC

PhotoMedex

XTRAC Lasers produce a highly effective, safe, and painless therapy by delivering a targeted, super-narrow UVB band to affected areas, resulting in effective and rapid improvement without the worry of harmful side effects of invasive, systemic agents.
