


chronic, itchy skin condition that is very
common in children but may occur at any age
clinical features may include itching, redness,
scaling and clustered papulovesicles
wide range of external and internal factors
acting singly or in combination

An inflammatory skin reaction characterized
histologically by spongiosis with varying
degrees of acanthosis, and a superficial
perivascular lymphohistiocytic infiltrate.


Incidence

1:5 children, 65% resolved by 7 yrs, 74% by 16

If more severe less likely to grow out of it

33% new presentations in adults

Aetiology

Both genetic and environmental factors

'atopic tendency‘ ie three closely linked conditions; atopic
dermatitis, asthma and hay fever, often in families






Mutations in the filaggrin gene
Thought to underlie almost half the cases of
atopic eczema
Filaggrin is critical to the conversion of
keratinocytes to the protein/lipid squames that
compose the stratum corneum, the outermost
barrier layer of the skin, so
A primary defect in the skin barrier function
Immunological changes are probably
secondary to enhanced antigen penetration
through a deficient epidermal barrier, hence
EMOLLIENTS!

Triggers
Flares ofton result of triggers, which aren’t the
same for everyone

Soap and detergents

Overheating / rough clothing

Skin infection






Animal dander (fur, hair) and saliva - if resulting from
a pet symptoms often improve when patients spend
time in a different environment for a few days
Aeroallergens (pollens) - reactions to airborne allergens
may cause a worsening of symptoms (often facial) over
spring / summer in those sensitised. This is most
commonly seen in older children and adults
Food – primarily in infants and young children (see
later under management)
House-dust mites and their droppings - sensitised
patients may notice a worsening of facial eczema when
they wake up
Stress





Diagnostic features
Personal or family history of atopy
Itch
Many patients have more troublesome symptoms in winter as a
result of central heating drying the skin out

Acute exacerbation


Long term management

Stratum corneum in non eczematous skin differs
from eczematous skin and this is probably lifelong,
So emphasizes the need for very long term
emollients



Time to discuss the condition, advise on how
best to use emollients and to provide an
individual management plan
Provide patient information leaflets and/or
direct to appropriate websites
At each step it is essential to ensure patient
compliance and to make sure that copious
amounts of emollients are being used








Presenting with a flare of eczema
More effective to hit hard with a short duration
of more potent steroid
Wet skin swab
Betamethsone/mometasone + antibiotic for 7
days
Localised -> fucibet
Sleep disturbance -> sedating antihistamine
Emollients
Review 2-3 weeks







Longer term management
Emollients - should be the mainstay of
therapy. Good evidence shows that the more
emollients are used, the less topical steroids are
needed.

Moisturisers
May need to try several to suit
Don’t use aq cream as a ‘leave on’ emollient
Most prefer creams/gels > ointments
Ointments less likely to cause allergic
dermatitis as fewer preservatives
Generous amounts, e.g. 500 g. of moisturisers
to use regularly (often QDS)
Gently rub until not grossly visible
Apply in direction of hairs to reduce risk of
folliculitis

Moisturisers 

May sting for several days…..then soothe

Ointments come in tubs and so can easily
become cross infected with bacteria from the
skin – patients must not place hands into tubs
but instead use a utensil to scoop out the
ointment





Bath / shower gels
Frequent flares may benefit from emollients
with an anti-septic property e.g. Dermol ® 600
Bath Emollient or 200 Shower Emollient,
Emulsiderm ® Liquid Emulsion or Oilatum ®
Plus Bath Additive
Very itchy skin may benefit from an emollient
with an anti-pruritic property such as
Balneum-plus ® Bath Oil
Pat dry after bathing
But poor mobility & falls due to the increased
risk of slipping in the bath or shower



Soap substitutes
Soaps make a lather, but they damage the skin
barrier and so should be avoided
specific soap substitutes can be prescribed it is
probably more cost effective to use one of the
prescribed moisturisers as a wash



lowest appropriate potency and only apply
thinly to inflamed skin
Allow to emollient to dry into skin for 15 - 20
minutes before applying steroid
Avoid using combined steroid/antibiotic
preparations on a regular basis (resistance)
Prescribe adequate amounts!

Strength of steroid to be determined by the age of
patient, site and severity:
Child face: mild potency e.g. 1%
Hydrocortisone
Child trunk and limbs: moderate potency e.g.
Eumovate ® (Clobetasone butyrate 0.05%) or
Betnovate-RD ® (Betamethosone valerate
0.025%)



Adult face: mild or moderate potency e.g.
Eumovate
Adult trunk and limbs: potent e.g. Betnovate ®
(Betamethasone valerate 0.1%), Elocon ®
(Mometasone)
Palms and soles: potent or very potent e.g.
Dermovate ® (Clobetasol propionate 0.05%)

Side effects
If used appropriately it is uncommon to develop
steroid atrophy, however extra care needs to be
taken in the following sites:
Around the eyes: unless used very infrequently
topical steroid preparations should be avoided due
to the risks of glaucoma
The face - the regular use of topical steroids should
be avoided
Lower legs in older patients / others at risk of leg
ulcers - as above



Flares
4 – 8 weeks - as per earlier slide
More frequent
Check compliance
 Swab the skin - for frequent infections it is useful to take
nasal swabs and if positive for S.Aureus treat with nasal
Bactroban ® cream BD for one week


Elocon ‘weekend regime’ for both children and
adults
OD for two weeks and then alternate days for a further
two weeks
 use Elocon on two consecutive days (e.g. Sat Sun) of each
week to the areas that tend to flare. The treatment must
be applied even if the skin in not inflamed – the aim is to
reduce the frequency of flares




Protopic ® ointment (an immunomodulator) - as above
the eczema first needs to be brought under control by
more frequent use of the proptopic and then reduce
down to twice a week eg at weekends. A so called
‘weekend regime’.
Patients not responding to the above - consider the
possibility of a contact allergic dermatitis
In this area referral to a dermatologist appropriate




Eczema tends to be persistent, most people will
have to use topical steroids on and off for many
years
Used continuously topical steroids may lose
their effectiveness after a few weeks
Avoid by reducing the strength and frequency
of the topical steroid as the eczema comes
under control.
Mild eczema responds well to topical steroids
and maintained with emollients alone


Moderate and severe eczema are more difficult
to manage. The eczema may not have
completely cleared with a potent topical steroid
after three to four weeks.
Manage by




Changing to an equipotent steroid prep
Treat infection
Gradually reducing the number of days the stronger
topical steroid is used, for example using a potent
topical steroid at weekends and an emollient on
weekdays
Hence the ‘weekend regimes’.
