What is atopic dermatitis?

It is a chronic skin disease that causes red and itchy skin. It usually affects children but it may occur at any age. It may be accompanied by fever and asthma.

Causes of atopic dermatitis

The normal healthy skin helps retain moisture and protects you from bacteria, allergens, and irritants.

Atopic dermatitis or eczema as also called is related to a gene variation that affects the skin's ability for this protection. So, any environmental factors and irritants affect the skin.

Also, food allergens may cause eczema in some children.

2-Raw, sensitive, swollen skin from scratching

3-Small, raised bumps that leak fluid and crust over when scratched

4-Dry skin

5-Itching, which may be severe, especially at night

6-Red to brownish-gray patches, especially on the hands, feet, ankles, wrists, neck, upper chest, eyelids, inside the bend of the elbows and knees, and in infants, the face and scalp.

Chronic itchy, scaly skin

Neurodermatitis (lichen simplex chronicus)

 Eventually, you may scratch simply out of habit. This condition causes the affected skin to become discolored, thick, and leathery.

Irritant hand dermatitis

This affects people whose hands are often wet and exposed to harsh soaps, detergents, and disinfectants.

Allergic contact dermatitis

It is common in people with atopic dermatitis.

Sleep problems

The itch-scratch cycle causes sleep anxiety.

If you suspect a certain food causes your child's rash, tell the doctor and ask about identifying food allergies.

Treatment of atopic dermatitis

It is a persistent disease that needs months or even years to control.

The signs and symptoms are flares that return even after successful treatment.  It is divided into:

medications

It may be a corticosteroid cream or ointment, using it after moisturizing the skin. Overuse of this drug thinning skin.

There are other creams containing calcineurin inhibitors like tacrolimus (Protopic) and pimecrolimus (Elidel) that affect the immune system.

2-Drugs to fight infection

3-Oral drugs that control inflammation

oral corticosteroids such as prednisone are prescribed for more severe cases.

These drugs are effective but can't be used for a long time because of their potentially serious side effects.

4-A newer option for severe eczema

The (FDA) has recently approved a new, injectable biologic (monoclonal antibody) called dupilumab).

 It is used to treat people with severe cases who do not respond well to other medications.

Therapies which include

1-Light therapy

Phototherapy is less commonly used in young children with atopic dermatitis and not given to infants due to its harmful effects in the long term use including premature skin aging and an increased risk of skin cancer.

2-Wet dressings
