Atopic Dermatitis (Eczema)

Atopic dermatitis is a chronic skin condition that causes patches of dry, red, and intensely itchy skin. Also called eczema, it often starts in childhood but can affect anyone at any age. The condition comes and goes in cycles, with periods of flare-ups followed by times when symptoms calm down.

When you have atopic dermatitis, your skin barrier does not work as it should. This means your skin loses moisture easily and allows irritants, allergens, and bacteria to get in. The result is inflammation, redness, and that maddening itch that makes you want to scratch constantly. The scratching creates more damage and can lead to infection.

This condition is not contagious and cannot spread from person to person. It often appears alongside other conditions like asthma, hay fever, and food allergies. These conditions share a common feature where your immune system overreacts to things that should not cause problems. Understanding what triggers your flare-ups is key to managing atopic dermatitis long-term.

Atopic dermatitis symptoms can vary from person to person and may change over time. Common signs include:

• Dry, sensitive skin that feels rough or scaly
• Intense itching, especially at night
• Red to brownish-gray patches on the skin
• Small raised bumps that may leak fluid and crust over when scratched
• Thickened, cracked, or leathery skin from repeated scratching
• Raw, swollen, or tender skin from scratching
• Dark patches around the eyes or on eyelids
• Patches on hands, feet, ankles, wrists, neck, chest, or eyelids

In babies, the rash often appears on the face and scalp. Children and adults typically see patches in skin folds like inside the elbows and behind the knees. Some people experience mild symptoms while others deal with severe discomfort that affects sleep and daily activities.

Atopic dermatitis develops from a combination of genetic factors, immune system responses, and environmental triggers. If your parents had eczema, asthma, or hay fever, you have a higher chance of developing it too. Your genes affect how well your skin can hold moisture and protect against irritants and allergens. When your skin barrier is weak, allergens and irritants can trigger an immune response that causes inflammation.

Specific triggers vary by person but often include allergens like dust mites, pet dander, pollen, and mold. Blood tests can reveal allergies to substances like sweet vernal grass, Arizona cypress, birch, and Alternaria alternata mold, all of which may trigger flare-ups. Food allergies to items like green beans and rice may also play a role in some cases. Your immune system produces too much interleukin-4, a protein that promotes inflammation and the production of IgE antibodies. These antibodies cause allergic reactions. Other triggers include harsh soaps, detergents, stress, sweat, temperature changes, and certain fabrics like wool.

Doctors diagnose atopic dermatitis by examining your skin and asking about your symptoms and medical history. They look at where the rash appears, how long you have had it, and whether family members have similar conditions. There is no single test that confirms eczema, but blood tests can identify underlying allergies and immune system activity that contribute to flare-ups.

Blood work can measure eosinophils, white blood cells that increase during allergic reactions and inflammation. Tests for allergen-specific IgE antibodies can pinpoint triggers like pollen, mold, and foods that worsen your symptoms. Interleukin-4 levels in your blood show how active your inflammatory pathways are. Rite Aid offers testing at Quest Diagnostics locations that measures these biomarkers, helping you and your doctor understand what drives your atopic dermatitis. This information guides treatment decisions and helps you avoid specific triggers.

Treatment for atopic dermatitis focuses on healing the skin, preventing flare-ups, and managing symptoms. A combination of approaches works best:

• Apply moisturizers multiple times daily to strengthen your skin barrier and lock in moisture
• Use gentle, fragrance-free soaps and detergents that do not strip your skin
• Take lukewarm baths or showers instead of hot ones, which dry out skin
• Apply prescription corticosteroid creams or ointments to reduce inflammation during flare-ups
• Try calcineurin inhibitors like tacrolimus or pimecrolimus for sensitive areas like the face
• Use antihistamines to reduce itching, especially at night
• Avoid known allergens and triggers identified through blood testing
• Manage stress through relaxation techniques, as stress can trigger flare-ups
• Wear soft, breathable fabrics like cotton and avoid wool or synthetic materials
• Consider biologic medications like dupilumab for severe cases that do not respond to other treatments

Work with a dermatologist or allergist to create a personalized treatment plan based on your test results and symptom patterns. Getting proper testing helps identify specific allergens so you can avoid them and reduce flare-ups.
