Atopic Dermatitis

WHAT IS ATOPIC DERMATITIS?

Atopic dermatitis is a rash that occurs in up to 20% of infants and 3% of the U.S. population as a whole. The rash presents usually as an itching dermatitis which can lead to intense burning and discomfort. With time, atopic dermatitis improves. However, approximately 60% of those who develop the disorder in childhood have some degree of eczema that occurs throughout their lifetime.

WHAT AGGRAVATES ATOPIC DERMATITIS?

Direct manipulation of eczematous areas can promote secondary infection and aggravate the condition. It is important to avoid placing irritating substances on the skin, such as alcohol, propylene glycol, or lanolin based products. These agents can intensify the rash. The use of emollients and topical corticosteroid creams along with reducing water temperature can be useful in treating the disorder.

HOW DOES ONE RECOGNIZE ATOPIC DERMATITIS?

When assessing atopic dermatitis it is important to determine whether or not the patient has a history of hay fever, pollen or dust allergies. The skin of those with atopic dermatitis is described as "dull or lusterless". The rash often occurs behind the elbows or knees. In younger patients, dermatitis involves the scalp and the face. Patients often have increased line markings of the hands and crusting spots on the fingers.

WHAT OTHER FACTORS CAN AGGRAVATE ATOPIC DERMATITIS?

Interestingly, there are certain food groups which can aggravate this type of rash, especially in younger children. Food products containing milk, soy, eggs, fish, wheat or peanuts have been implicated. If one suspects food intolerance, it is important to avoid these products for at least one to two weeks to see if the rash improves. Allergy testing is sometimes required.

WHAT ARE SOME OF THE ENVIRONMENTAL FACTORS THAT SHOULD BE AVOIDED?

Pillows, down comforters and mattresses that contain feathers can often make symptoms worse. It is important to consider the materials that contact the skin when assessing atopic dermatitis. Patch testing is also sometimes helpful. This is a way to see which chemical or agents are responsible for rash development.

Are allergy shots helpful in the treatment of atopic dermatitis?

Not usually. In fact, they sometimes cause the dermatitis to become more intense.
