The many “FACIES” of Atopic Eczema

Very dry skin-may be an early manifestation of AE

Prophylactic Moisturisation

• Full body application of moisturisers for 6-8 months beginning in the first month of life for high risk infants showed a cumulative reduced incidence of AD

The many “FACIES” of Atopic Eczema

The many “FACIES” of Atopic Eczema

Infant phase(birth to 2 years)

• face, scalp, extensors of limbs

• cheeks, spares perioral and perinasa

• chin, cheilitis

• spares nappy area

AE distribution evolve over months/years

You can objectively confirm AE, using the UK working party criteria

You can objectively confirm AE, by searching for

The many “FACIES” of Atopic Eczema

The many “FACIES” of Atopic Eczema

Education

Soap substitutes

Optimal topical care (emollients)

Specific therapy:

corticosteroids / calcinuerin inhibitorsAntihistamines systemic therapy –e.g. Azathioprine, Methotrexateultraviolet light therapy

Management principles – AE (to control the disease)

• Work with patients and parents as a team.

– Education

– Written instructions

– Address steroid phobia

Education in AE

Avoiding triggers

• Soaps ( use emollient wash products)

• Bubble baths

• Woolen or rough fabric clothes

• Fragrances

• Aggressive antiseptics

• Shampoos with high content sodium lauryl sulphate

• ?cats

• Sweat (use wet wraps)

• Dry climates (increase frequency of moisturizing)

Atopic Eczema - a chronic skin disease

Bathing Practice

• Bath/ shower once a day in warm (not hot) water

• Avoid soap

• Use a soap substitute such as aqueous cream

– bath oils, liquid paraffin

• Pat dry

Moisturisers

Basis of management

Should be used continuously even when skin is clear

• ?Ideal moisturiser: unperfumed, low pH

• Guided by patients needs and preferences

– Emulsifying ointment or cetomacrogol or Vaseline

– Avoid aqueous cream

• Applied frequently, after bathing and swimming

• Within 3 min of a luke warm bath or shower

• Prescribed in large quantities (250g/wk)

Topical corticosteroids

Mainstay of pharmacological treatment

vast majority respond very rapidly to adequate topical steroid treatment

But:

-need adequate quantities

-need correct potency (mid to high potent)

-steroid phobia

-applied for maximum 2 weeks, before side effects occur

Prescribing topical steroids -Vehicle:

Ointment – dry eczema

Lotion- wet eczema or scalp

Creams – wet eczema or eczema in folds

Gel - scalp and wet eczema

Quantity

Do not under-prescribe!

Prescribing topical steroids

• Once daily as effective as twice daily

• Acute flare:

– Intermittent use 7-14 days with emollient only “steroid holidays”

– Short bursts may be needed for flares

– Start potent , wean down

• Maintenance:

– Least potent that controls disease

– “weekend therapy”

Topical calcineurin inhibitors

• Not cause skin atrophy

• Pimecrolimus 1% (Elidel) is approved for mild AD, less effective than betamethasone

• Tacrolimus (0.03%) is superior

• May be useful for face, periorbital and intertriginous areas

Adjuvant therapy-in AE

NICE UK GUIDELINES

The many “FACIES” of Atopic Eczema

Benefits- Wet wrap therapy

• Ancient practice - in Babylon and Egypt

• To cool skin, anti-inflammatory, itch reduction

• For severe , refractory AD

• Safe and effective

• Biggest barrier: it’s time consuming

Side effects- Wet wrap therapy

• Increased infectious complications- folliculitis, impetigo, herpes

• Skin atrophy, striae, easy bruising, hypopigmentation, telangiectasia, steroid acne, steroid rosacea, hirsutism, contact dermatitis

• Rare: suppression of HPA axis, growth retardation, cataracts, glaucoma, tachyphylaxis, Cushing's

Conclusions• there are many facies of atopic eczema

• intervene appropriately depending on the stage of AE

• the vast majority will respond to optimal topical care

– Emollients

– Topical corticosteroids/TCIs

• moderate-severe AE require WWT -acute intervention

• WWT should be considered as a treatment option ahead of systemic immunosuppressives
