What is Atopic Dermatitis?

Atopic dermatitis is a chronic skin disease characterised by inflammation, redness and irritation. Skin often appears red, dry, crusted, cracked and swollen.

The onset of atopic dermatitis can occur at any age but it often happens between the ages of 3 to 6 months old. It is common for individuals with atopic dermatitis to go through flares (when symptoms worsen) and remissions (when the skin gets better or clears up completely).

Signs & symptoms of atopic dermatitis

The most common symptom of atopic dermatitis is severe itchiness. Other common signs include:

Raw, sensitive skin resulted from severe scratching
Discoloured patches of skin
Dry, cracked skin
Rashes that bleed or ooze clear fluid when scratched

Types of dermatitis

Seborrheic dermatitis

Mainly affects the scalp that causes dandruff, scaly patches and inflammation.

Nummular dermatitis

Also known as discoid eczema, mostly occurs on the forearms, hands and lower legs, and causes coin-shaped plaques of dermatitis.

Dyshidrotic dermatitis (pompholyx)

Primarily affects the hands or feet, and causes itchy blisters.

Diaper dermatitis (rash)

Common among infants, it is caused by moisture in the diaper area which promotes bacterial growth.

Contact dermatitis

Occurs when coming in contact with foreign substances such as chemicals in soap or water.

Perioral/periorificial dermatitis

Mainly affects the area around the mouth.

Varicose dermatitis

Common among people with varicose veins (swollen and enlarged veins) and primarily affects the lower legs.

What causes atopic dermatitis?

The causes of atopic dermatitis include genetics, environmental triggers and immune system issues. However, it is not contagious.

Several factors increase your likelihood of developing atopic dermatitis. These include:

A history of dermatitis, asthma or hay fever in the family

Excessively dry, itchy skin

Skin infections

Atopic dermatitis can be triggered from:

Tobacco smoke

Certain types of air pollutants

Heat and sweat

Rough fabric

Cold and dry air

Fragrances found in daily items such as skin products, detergents and soap

Chemicals and other irritants (e.g. fluoride found in toothpaste or water)

Diagnosis for atopic dermatitis

Your doctor will examine your skin to look for signs of atopic dermatitis such as scales, dry patches, rash and more.

The doctor may also ask about your family history on allergies, enquire about any previous treatment for skin-related symptoms and usage of medications such as steroids.

Blood testing may be done to look for potential causes that are unrelated to the dermatitis that the patient is experiencing. Doctors may also recommend patch testing to identify the allergies that are producing dermatitis.

Treatment for atopic dermatitis

Your doctor may propose a self-care routine if the symptoms are mild. Routines may include:

Managing stress levels

Eating a healthy diet

Getting good rest

Using an unscented, mild soap

Having regular baths and moisturising routine for improving and protecting the skin barrier

Your dermatologist might suggest medicated creams that control itching and help repair skin. If your symptoms persist, the self-care routines can be combined with other treatments:

Topical therapy which includes moisturiser, antiseptic/antimicrobial agents and anti-inflammatory agents

Topical corticosteroids such as Triamcinolone acetonide 0.1% cream, Clobetasone butyrate 0.05% cream/ointment

Topical calcineurin inhibitors such as pimecrolimus and tacrolimus

Wet wrap therapy - The affected area is layered with moisturiser alone or in combination with topical corticosteroids. It is then covered with two layers of tube bandage (a wet inner layer and a dry outer layer).

Phototherapy

Systemic therapy includes specific treatment (immunomodulating agents and biologics) and adjunctive treatment (antihistamines)

Topical therapy which includes moisturiser, antiseptic/antimicrobial agents and anti-inflammatory agents

Topical corticosteroids such as Triamcinolone acetonide 0.1% cream, Clobetasone butyrate 0.05% cream/ointment

Topical calcineurin inhibitors such as pimecrolimus and tacrolimus
