Atopic Dermatitis in Children
What is atopic dermatitis?Atopic dermatitis is a long-term (chronic) skin condition. It causes itchy skin. It’s a very common condition. It’s more common in babies and children, but also occurs in adults. It usually first appears between ages 3 to 6 months.
What causes atopic dermatitis?
The exact cause of atopic dermatitis is not known. But some factors are linked to it, such as:
- Genes. This skin problem can be passed on from parents to a child.
- The immune system. An immune system that isn’t fully developed may affect the protective ability of the skin.
- External factors. These include winter weather, using hot water for bathing, using soap, and dry, hot temperatures.
Who is at risk for atopic dermatitis?
A child has a greater chance of having atopic dermatitis if he or she has:
- Family members with atopic dermatitis
What are the symptoms of atopic dermatitis?
Symptoms may come and go, or occur most or all of the time. Any area of the body may be affected. In babies, symptoms usually affect the face, neck, scalp, elbows, and knees. In children, symptoms usually affect the skin inside the elbows, on the back of the knees, the sides of the neck, around the mouth, and on the wrists, ankles, and hands.
Symptoms can occur a bit differently in each child. They can include:
- Dry, scaly skin
- Severe itching
- Redness and swelling
- Thickened skin
- Pale skin on the face
- Small, raised bumps that may become crusty and leak fluid if scratched
- Rough bumps on the face, upper arms, and thighs
- Darkened skin of eyelids or around the eyes
- Skin changes around the mouth, eyes, or ears
- Raised, red areas (hives)
The symptoms of atopic dermatitis can be like other health conditions. Make sure your child sees his or her healthcare provider for a diagnosis.
How is atopic dermatitis diagnosed?
The healthcare provider will ask about your child’s symptoms and health history. He or she may also ask if you or other family members have atopic dermatitis, asthma, or nasal allergies such as hay fever or allergic rhinitis. He or she will also ask about allergy symptoms in your child. The healthcare provider will examine your child, looking for signs of atopic dermatitis. There is no specific test for atopic dermatitis. Testing is usually not needed, but it may be done. Tests may include:
- Blood tests. Your child’s blood may be checked for levels of immunoglobulin E (IgE). IgE is released by the body's immune system. It’s high in most children with allergies and with atopic dermatitis. Other blood tests may be done too.
- Skin tests. Skin tests may be done to check for allergies or other skin conditions.
How is atopic dermatitis treated?
Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is. There is no cure for atopic dermatitis. The goals of treatment are to reduce itching and inflammation, add moisture, and prevent infection.
Treatment of atopic dermatitis includes:
- Staying away from irritants, as advised by your child's healthcare provider
- Regular bathing with a gentle cleaner or body wash advised by the healthcare provider
- Keeping your child's fingernails short, to help prevent scratching that can cause skin irritation and infection
- Using moisturizing lotion advised by the healthcare provider
Your child's healthcare provider may also prescribe medicines. They may be used alone or together. The following are most commonly used to treat atopic dermatitis:
- Corticosteroid cream or ointment. The cream or ointment is applied to the skin. This is to help lessen itching and swelling.
- Antibiotic medicine. Liquid or pills may be taken by mouth to treat infection.
- Antihistamine. This medicine may be taken before sleep to help decrease itching and improve sleep. It comes in liquid or pills and is taken by mouth.
- Calcineurin inhibitor cream or ointment. Cream or ointment is applied to the skin. This is to help lessen itching and swelling.
- Phototherapy (light therapy). Light therapy may be done in the healthcare provider's office or at home.
- Immunomodulatory medicine. This is a liquid or pill taken by mouth that affects the immune system. It may be used when other treatments do not work well. This medicine may have side effects. Your child will have regular blood tests to check for side effects.
What are possible complications of atopic dermatitis?Atopic dermatitis can cause thickened skin, bacterial skin infection, and other allergy-related skin inflammation (allergic dermatitis). It can also cause poor sleep because of intense itching. And it can lead to depression. Overuse of steroid creams can lead to thinning of the skin and tissue beneath the skin.
Can atopic dermatitis be prevented?The skin condition is passed on from parents to children, so it may not be possible to prevent it. But studies have found that the daily use of oil, cream, or ointment on the skin of babies at risk may prevent it from developing.
Living with atopic dermatitis
There is no cure for atopic dermatitis. But it will usually get better or go away as your child gets older. There may be times when your child has few or no symptoms. And he or she may have times when symptoms get worse. This is called a flare-up. To help prevent flare-ups, make sure your child:
- Avoids triggers. Common triggers include irritants (such as wool, soap, or chemicals), allergens (eggs, dust mites, or pet dander), and stress.
- Doesn’t scratch the skin. Try to keep your child from scratching. It can cause worse symptoms and infection.
- Always has short fingernails. Trim or file your child’s nails to keep them short and prevent scratching.
- Takes warm baths or showers, not hot. Air dry or gently dry the skin afterward.
- Uses moisturizers. Apply creams or ointments after bathing.
- Wears soft clothing. Don’t dress your child in wool or other rough fabric.
- Keeps cool. Try to keep your child as cool as possible. Getting hot and sweating can make him or her more uncomfortable.
- Doesn’t get the smallpox vaccine. It’s not a common vaccine, but people with atopic dermatitis should not receive the smallpox vaccine.
Talk with your child's healthcare provider about other ways to help your child’s skin condition.
When should I call my child’s healthcare provider?
Call the healthcare provider if your child has:
- Symptoms that get worse
- Signs of a skin infection, such as increased redness, warmth, swelling, or fluid
- New symptoms
