are needed to determ<strong>in</strong>e the future role <strong>of</strong> immunotherapy<br />
for AD.<br />
Additional <strong>treatment</strong> options <strong>and</strong> future perspectives<br />
The development <strong>of</strong> new, targeted therapeutic approaches<br />
is based on an <strong>in</strong>creas<strong>in</strong>g knowledge <strong>of</strong> the cellular <strong>and</strong><br />
molecular aspects <strong>in</strong> <strong>atopic</strong> diseases. Most <strong>of</strong> the new<br />
approaches aim at <strong>in</strong>hibit<strong>in</strong>g components <strong>of</strong> the allergic<br />
<strong>in</strong>flammatory response, <strong>in</strong>clud<strong>in</strong>g cytok<strong>in</strong>e modulation<br />
(eg, TNF <strong>in</strong>hibitors) (185, 186), blockade <strong>of</strong> <strong>in</strong>flammatory<br />
cell recruitment (chemok<strong>in</strong>e receptor antagonists <strong>and</strong><br />
cutaneous lymphocyte antigen <strong>in</strong>hibitors) (187), <strong>and</strong> <strong>in</strong>hibition<br />
<strong>of</strong> T-cell activation (alefacept <strong>and</strong> efalizumab) (86).<br />
Education<br />
The goal <strong>of</strong> the patientsÕ education should be liv<strong>in</strong>g with<br />
<strong>atopic</strong> <strong>dermatitis</strong> by means <strong>of</strong> an empowered patient or,<br />
<strong>in</strong> the case <strong>of</strong> <strong>in</strong>fants <strong>and</strong> young <strong>children</strong>, a caregiver who<br />
can work as a partner with the doctor <strong>in</strong> selfmanag<strong>in</strong>g<br />
their own or their <strong>children</strong>’s disease.<br />
Education to enhance disease knowledge, psychologic<br />
improvement <strong>in</strong> disease perception, <strong>and</strong> scratch control<br />
behavior modification, together with regular daily <strong>treatment</strong>,<br />
will lead to better sk<strong>in</strong> care. This improvement <strong>in</strong><br />
disease control will restore family dynamics, <strong>and</strong> the<br />
patient <strong>and</strong> family will cope better <strong>and</strong> have an overall<br />
improvement <strong>in</strong> quality <strong>of</strong> life. Additionally, education<br />
should be aimed at reduc<strong>in</strong>g doctor shopp<strong>in</strong>g, facilitat<strong>in</strong>g<br />
a better partnership between the doctor <strong>and</strong> the patientparent,<br />
<strong>and</strong> decreas<strong>in</strong>g the long-termcosts <strong>of</strong> chronic<br />
disease <strong>treatment</strong>.<br />
Many prelim<strong>in</strong>ary studies have been s<strong>in</strong>gle nurse-led<br />
<strong>in</strong>terventions that were usually not controlled to assess<br />
outcomes (188). From the recent controlled studies, there is<br />
the general impression that positive outcomes are dependant<br />
on the time spent with parents <strong>and</strong> the qualification <strong>of</strong><br />
the tra<strong>in</strong>er (189–191). Shar<strong>in</strong>g personal experiences <strong>in</strong><br />
manag<strong>in</strong>g AD was helpful <strong>in</strong> 80% <strong>of</strong> those parents<br />
attend<strong>in</strong>g the program conducted by Staab et al. (192).<br />
A 12-lesson educational program(192) described positive<br />
outcomes after 1 year, <strong>in</strong>clud<strong>in</strong>g dim<strong>in</strong>ished fear <strong>of</strong><br />
topical corticosteroid cream use. In a recent German<br />
multicenter study 820 <strong>children</strong> with AD were r<strong>and</strong>omized<br />
<strong>in</strong>to an <strong>in</strong>tervention group (n ¼ 443) <strong>and</strong> a control group<br />
(n ¼ 377) (193) The <strong>in</strong>tervention group underwent a 12hour<br />
education program on an outpatient basis. After<br />
1 year, the overall Severity Score for Atopic Dermatitis<br />
(SCORAD) measure, quality <strong>of</strong> life, scratch<strong>in</strong>g <strong>in</strong>dex, <strong>and</strong><br />
adherence to <strong>treatment</strong> showed statistically significant<br />
improvement.<br />
Fundamentally, each patient with AD should be<br />
educated on various aspects <strong>of</strong> the disease. For economic<br />
<strong>and</strong> practical reasons, structured education will target<br />

patients with moderate <strong>and</strong> severe chronic AD <strong>and</strong> their<br />
parents. Structured patient education should enable both<br />
the patient <strong>and</strong> the parent to have realistic short-term<br />
goals, enter a process <strong>of</strong> problem solv<strong>in</strong>g, accept liv<strong>in</strong>g<br />
with their disease, appropriately use available social<br />
support, <strong>and</strong> enhance their own motivation for therapy.<br />
Potential approaches for primary <strong>and</strong> secondary prevention<br />
<strong>of</strong> AD<br />
Based on the idea <strong>of</strong> diet as modulatory, a number <strong>of</strong><br />
controlled <strong>in</strong>terventions have tested this hypothesis <strong>of</strong><br />
primary prevention through the nutritional route. Hydrolyzed<br />
cow’s milk formula consists <strong>of</strong> predigested peptides<br />
<strong>of</strong> whey <strong>and</strong> case<strong>in</strong>. The formulas have equivalent<br />
nutritional values but a reduced capacity to <strong>in</strong>duce<br />
IgEmediated reactions (194–197). A large controlled<br />
study <strong>in</strong> high-risk <strong>in</strong>fants us<strong>in</strong>g different partially <strong>and</strong><br />
extensively hydrolyzed formulas for the first 6 months <strong>of</strong><br />
life demonstrated that extensively hydrolyzed case<strong>in</strong><br />
formula has the capacity to reduce AD by 50% <strong>in</strong> the<br />
first year <strong>of</strong> life (198, 199). A different approach for<br />
primary prevention is suggested by the <strong>in</strong>troduction <strong>of</strong><br />
probiotics (Lactobacillus GG) <strong>in</strong>to the maternal <strong>and</strong><br />
<strong>in</strong>fantile diet. One study reported a decreased <strong>in</strong>cidence <strong>of</strong><br />
AD but had no effect on allergic sensitization (200).<br />
Elim<strong>in</strong>ation diets <strong>in</strong> the mother are not recommended<br />
because <strong>of</strong> their limited success. Other potential avenues<br />
that are be<strong>in</strong>g explored <strong>in</strong>clude add<strong>in</strong>g bacterial, mycobacterial,<br />
<strong>and</strong> parasitic materials <strong>in</strong>to the <strong>in</strong>fant diet.<br />
A secondary prevention trial with cetiriz<strong>in</strong>e for<br />
<strong>in</strong>fants with AD <strong>and</strong> a positive family history <strong>of</strong><br />
asthma failed to demonstrate an effect for the whole<br />
group. In a subset <strong>of</strong> patients with dust mite or grass<br />
pollen sensitization, the <strong>in</strong>cidence <strong>of</strong> asthma was<br />
reduced by 50% (20). This concept is currently be<strong>in</strong>g<br />
<strong>in</strong>vestigated <strong>in</strong> a second trial <strong>of</strong> 500 <strong>children</strong> (20). Trials<br />
us<strong>in</strong>g environmental control measures have shown<br />
potential effects <strong>in</strong> AD severity <strong>in</strong> <strong>children</strong>, although<br />
not <strong>in</strong> adults (16). Another secondary prevention trial is<br />
under <strong>in</strong>vestigation based on the early <strong>treatment</strong> <strong>of</strong> AD<br />
with topical pimecrolimus to prevent the progression <strong>of</strong><br />
AD to asthma based on the concept that the sk<strong>in</strong> is the<br />
primary site <strong>of</strong> sensitization.<br />
