The word atopic means there is a tendency for excess inflammation in the skin and linings of the nose and lungs. This often runs in families with allergies such as hay fever and asthma, sensitive skin or a history of atopic dermatitis. Although most people with atopic dermatitis have family members with similar problems, 20% of them are the only ones in their family with the condition.
Atopic dermatitis is very common in all parts of the world. It affects about 10% of infants and 3% of the total population in the United States. It can occur at any age but is most common in infants to young adults. The skin rash is very itchy and can be widespread or limited to a few areas. The condition frequently improves with adolescence but many patients are affected throughout life, although not as severely as in early childhood.
Other eczema patches in this stage are typically dry, red to brownish-gray and may be scaly or thickened. The thickened areas may last for years without treatment. The intense, almost unbearable itching can continue and may be most noticeable at night. Some patients scratch the skin until it bleeds and crusts. When this occurs, the skin can get infected.
Since the disease does not always follow the same pattern, proper, early and regular treatment can bring relief and may reduce the severity and duration of the disease.
Q. Since this condition is associated with allergies, can certain foods be the cause?
A. Rarely (perhaps 10% of the time). Although some foods may provoke atopic dermatitis, especially in infants and young children with asthma, eliminating those foods is rarely a cure. You should eliminate any foods that cause immediate, severe reactions or welts.
Q. Are environmental causes important and should they be eliminated?
A. Rarely. The elimination of contact or airborne substances does not bring lasting relief. Occasionally, dust and dust-catching objects like feather pillows, down comforters, kapok pillows and mattresses, cat and dog dander, carpeting, drapes, some toys and wool and other rough fabrics can worsen atopic dermatitis.
Q. What should be done to treat this condition?
A. See your dermatologist for advice on avoiding irritating factors in creams and lotions; rough, scratchy, or tight clothing; and woolens. Rapid changes of temperature and any activity that causes sweating can aggravate atopic dermatitis. Proper bathing, moisturizing and dealing with emotional upsets that may worsen the condition can be discussed.
Your dermatologist can prescribe external medications such as steroids and newer immune-modifying creams. Internal medications such as antihistamines can help with the itch. Oral antibiotics may be prescribed if there is a secondary infection. For severe cases, your dermatologist may recommend ultraviolet light treatment, or other treatments.
