Other research questions, and their importance or relevance, are discussed in the full document. Management of Atopic Eczema in Children from Birth up to the Age of 12 Years This guideline has been subjected to peer review. The GDG also included lay people among its members to ensure patient representation. Issued by Date of Issue Date of Expiry National Collaborating Centre for Women’s and Children’s Health Commissioned by the National Insti- tute for Health and Clinical Excellence, United Kingdom (NICE) Citation 2007 Between 2011 and 2013 (review date is 4 years from publication date, or earlier; latest evidence considered was 21 March 2007) It should be noted that for managing bottle-fed infants under 6 months, the guideline failed to discuss the option of breastfeeding (re-lactation) and instead limited the recommendation to extensively hydrolysed protein formula or amino acid formula. Furthermore, in addition to the identified key research areas, the guideline also pointed out that the UK diagnostic criteria have not been tested extensively in non-white ethnic groups in the UK. Validation of this diagnostic criteria among Filipinos may be necessary. Summary of Recommendations Link to full text http://www.nice.org.uk/nicemedia/ live/11901/38559/38559.pdf; http://www.ga2len.net/464D9d01.pdf Summary of Critical Appraisal This guideline considered important options and outcomes in terms of diagnosis and management of atopic dermatitis in children. It should be noted however that the guideline does not intend to discuss primary prevention of AD among high risk individuals. An explicit process was followed by the Guideline Development Group (GDG) in accordance with the NICE guideline development process. Published literature was searched systematically but the grey literature was not. Stakeholder organizations were invited to submit evidence for review. Appraisal of evidence was done using established standard methods prescribed in the NICE Guidebook. A level of evidence was assigned for each study, and to the body of evidence for each question. For each clinical question, informal consensus methods were used to draft clinical and costeffectiveness evidence statements. Afterwards, formal consensus methods using modified Delphi technique were utilized for the final recommendations. Nominal group technique was used to shortlist the key or priority recommendations In the process, the GDG excluded recommendations that covered important aspects of the management of atopic eczema in children but which were thought to already reflect current practice in the UK. Therefore, the reader is advised to refer to the full text since locally relevant recommendations may have been excluded from the key or priority recommendations which are covered in this summary. The reader should also note that the strength of recommendation for the other items outside the eleven key areas for implementation are not indicated. Five priority research recommendations were also identified by the GDG. These research topics are listed in this summary to alert the reader that at the time this Guideline was issued, these research questions have Recommendations Strength Level of Recom- of mendations Evidence Diagnosis: A range of diagnostic criteria for atopic eczema in children have been described in the literature, but only the UK Working Party criteria have been assessed adequately for validity and repeatability. Atopic eczema should be diagnosed when a child has an itchy skin condition plus three or more of the following: 2+ DSII to III • visible flexural dermatitis involving the skin creases, such as the bends of the elbows or behind the knees (or visible dermatitis on the cheeks and/or extensor areas in children aged 18 months or under) • personal history of flexural dermatitis (or dermatitis on the cheeks and/or extensor areas in children aged 18 months or under) • personal history of dry skin in the last 12 months • personal history of asthma or allergic rhinitis (or history of atopic disease in a firstdegree relative of children aged under 4 years) • onset of signs and symptoms under the age of 2 years (this criterion should not be used in children aged under 4 years).

Assessment of severity, psychological and psychosocial wellbeing and quality of life Identification and management of trigger factors PRIORITY/ Healthcare professionals KEY should adopt a holistic RECOMapproach when assessing MENDATION a child’s atopic eczema at each consultation, taking into account the severity of the atopic eczema and the child’s quality of life, including everyday activities and sleep, and psychosocial wellbeing (see Table on Holistic assessment below). There is not necessarily a direct relationship between the severity of the atopic eczema and the impact of the atopic eczema on quality of life. 3 When clinically assessing children with atopic eczema, healthcare professionals should seek to identify potential trigger factors including: • irritants, for example soaps PRIORITY/ KEY and detergents (including shampoos, bubble baths, RECOMshower gels and washing- MENDATION up liquids) • skin infections • contact allergens • food allergens • inhalant allergens Epidemiology Healthcare professionals should inform children with atopic eczema and their parents or carers that the condition often improves with time, but that not all children will grow out of atopic eczema and it may get worse in teenage or adult life. 3 Healthcare professionals should inform children with 3 DS III 2 Healthcare professionals should consider a diagnosis of food allergy in children with atopic eczema who have reacted previously to a food with immediate symptoms, or in infants and young children with moderate or severe atopic eczema that has not been controlled by optimum management, particularly if associated with gut dysmotility (colic, vomiting, altered bowel habit) or failure to thrive.

Healthcare professionals should consider a diagnosis of allergic contact dermatitis in children with an exacerbation of previously controlled atopic eczema or with reactions to topical treatments. Healthcare professionals should reassure children with mild atopic eczema and their parents or carers that most children with mild atopic eczema do not need to have tests for allergies. Treatment Stepped approach to management Healthcare professionals should use a stepped approach for managing ato­pic eczema in children. This means tailoring the treatment step to the severity of the atopic eczema. Emollients should form the basis PRIORITY/ KEY of atopic eczema management and should always be RECOMused, even when the atopic MENDATION eczema is clear. Management can then be stepped up or down, according to the severity of symptoms, with the addition of the other treatments listed in Table on Treatment options (See above). Phototherapy Emollients Healthcare professionals should offer children with atopic eczema a choice of unperfumed emollients to use every day for moisturising, washing and bathing. This should be suited to the child’s needs and preferences, and may include a combination of products or one product for all purposes. Leaveon emollients should be prescribed in large quantities (250–500 g weekly) and easily available to use at nursery, pre-school or school. Topical corticosteroids 3 1- to 1+ The potency of topical corticosteroids should be tailored to the severity of the child’s atopic eczema, which may vary according to body site. They should be used as follows: •use mild potency for mild atopic eczema •use moderate potency for moderate atopic eczema •use potent for severe atopic eczema •use mild potency for the face and neck, except for short-term (3–5 days) use of moderate potency for severe flares •use moderate or potent preparations for short periods only (7–14 days) for flares in vulnerable sites such as axillae and groin •do not use very potent preparations in children without specialist dermatological advice.

Topical tacrolimus is recommended, within its licensed indications, as an option for the second-line treatment of moderate to severe atopic eczema in adults and children aged 2 years and older that has not been controlled by topical corticosteroids, where there is a serious risk of important adverse effects from further topical corticosteroid use, particularly irreversible skin atrophy. Pimecrolimus is recommended as an option for the second-line treatment of moderate atopic eczema on the face and neck in children aged 2–16 years that has not been controlled by topical corticosteroids Dry Bandages and Medicated Dressings (including wet wrap therapy) Occlusive medicated dressings and dry bandages should not be used to treat infected atopic eczema in children. Localised medicated dressings or dry bandages can be used with emollients as a treatment for areas of chro­ nic lichenified (localised skin thickening) atopic eczema in children. Whole-body (limbs and trunk) occlusive dressings (including wet wrap therapy) with topical corticosteroids should only be used to treat atopic eczema in children for 7–14 days (or for longer with specialist dermatological advice), but can be continued with emollients alone until the atopic eczema is controlled. Antihistamines Oral antihistamines should not be used routinely in the management of atopic eczema in children. 238 Healthcare professionals should offer a 1 month trial of a non-sedating antihistamine to children with severe atopic eczema or children with mild or moderate atopic eczema where there is severe itching or urticaria. Treatment can be continued, if successful, while symptoms persist, and should be reviewed every 3 months. Healthcare professionals should offer a 7–14 day trial of an age-appropriate sedating antihistamine to children aged 6 months or over during an acute flare of atopic eczema if sleep disturbance has a significant impact on the child or parents or carers. This treatment can be repeated during subsequent flares if successful. Treatment for infections a s sociated with atopic eczema Children with atopic eczema­ and their parents or carers should be offered information on how to recognise the symptoms and signs of bacterial infection with staphy­lococcus and/or streptococcus (weeping, pustules, crusts, atopic ­eczema failing to respond to therapy, rapidly worsening atopic eczema, fever and malaise). Healthcare professionals should provide clear information on how to access appropriate treatment when a child’s atopic eczema becomes infected. Children with atopic eczema and their parents or carers should be offered information on how to recognise eczema herpeticum. Signs of eczema herpeticum are: •areas of rapidly worsening, painful eczema •clustered blisters consist ent with early-stage cold sores •punched-out erosions (circular, depressed, ulcerated lesions) usually 1–3 mm that are uniform in appearance (these may coalesce to form larger areas of erosion with crusting) Eczema •possible fever, lethargy or distress. Phototherapy and Systemic treatments Phototherapy should be considered before systemic treatments unless there are contraindications such as very fair skin or family history of skin malignancies. Phototherapy and systemic treatments should be used only in severe cases of atopic eczema in children where other management options have failed or are not appropriate, and where the atopic eczema has a significant impact on quality of life. It is the GDG’s view that assessment and documentation of severity and quality of life should always be undertaken prior to initiating treatment with systemic treatments or phototherapy. Complementary Therapy Children with atopic eczema and their parents or carers should be informed that the effectiveness and safety of complementary therapies such as homeopathy, herbal medicine, massage, and food supple­ments for the management of atopic eczema have not yet been adequately asses­ sed in clinical studies. Children with atopic eczema and their parents or carers should be informed that: •they should be cautious with the use of herbal medicines in children and be wary of any herbal product that is not labelled in English or does not come with information about safe usage •topical corticosteroids are deliberately added to some herbal products intended for use in children with atopic eczema* •liver toxicity has been asso­ ciated with the use of some Chinese herbal medicines intended to treat atopic eczema. Children with atopic eczema and their parents or carers should be asked to inform their healthcare professionals if they are using or intend to use complementary therapies. Children with atopic eczema and their parents or carers should be informed that if they plan to use complementary therapies, they should keep using emollients as well. Children with atopic eczema and their parents or carers should be advised that regular massage with emollients may improve the atopic eczema. Education and adherence to therapy PRIORITY/ KEY RECOMHealthcare professionals should spend time educating MENDATION children with atopic eczema and their parents or carers about atopic eczema and its treatment. They should provide information in verbal and written forms, with practical demonstrations, and should cover: •how much of the treat ments to use •how often to apply treatments •when and how to step treatment up or down • how to treat infected atopic eczema. This should be reinforced at every consultation, addres­ sing factors that affect adherence. Monitoring growth The GDG believes that it is cost-effective to monitor growth in children with atopic eczema that requires ongoing treatment. The aim of monitoring should be to identify failure to thrive (which may reflect the severity of the atopic eczema), and therefore inform treatment decisions, including referral. Failure to thrive in atopic eczema often indicates another problem (such as nutritional deficiency or food allergy). Early identification of failure to thrive (discrepancy between height and weight, or stunted growth) may prevent later morbidity www.TheFilipinoDoctor.com l Sign up and open your clinic to the world. 239 Eczema Indications for referral Referral for specialist derma­ tological advice is recommended for children with atopic eczema if: •the diagnosis is, or has PRIORITY/ become, uncertain KEY •management has not con- RECOMtrolled the atopic eczema MENDATION satisfactorily based on a subjective assessment by the child, parent or carer (for example, the child is having 1–2 weeks of flares per month or is reacting adversely to many emollients) •atopic eczema on the face has not responded to appro­ priate treatment •the child or parent/carer may benefit from specialist advice on treatment application (for example, bandaging techniques) •contact allergic dermatitis is suspected (for example, persistent atopic eczema or facial, eyelid or hand atopic eczema) •the atopic eczema is giving rise to significant social or psychological problems for the child or parent/ carer (for example, sleep disturbance, poor school attendance) •atopic eczema is asso­ ciated with severe and recurrent infections, especial­ ly deep abscesses or pneumonia. Key Priorities for Research 1.What is the optimal feeding regimen in the first year of life for children with established atopic eczema? 2.Which are the best, most cost-effective treatment strategies for managing and preventing flares in children with atopic eczema? 3.What effect does improving the control of atopic eczema in the first year of life have on the longterm control and severity of atopic eczema and the subsequent development and severity of food allergy, asthma and allergic rhinitis? 4.What are the long-term effects (when used for between 1 and 3 years) of typical use of topical corticosteroids in children with atopic eczema? 5.How effective and cost-effective are different models of educational programmes in the early management of atopic eczema in children, in terms of improving adherence to therapy and patient outcomes such as disease severity and quality of life? 240 Levels of Evidence Levels of evidence for intervention studies Level Source of evidence 1++ 1+ 1- 2++ 2+ 2- 3 4 High-quality meta-analyses, systematic reviews of randomized controlled trials (RCTs) or RCTs with a very low risk of bias Well-conducted meta-analyses, systematic reviews of RCTs or RCTs with a low risk of bias Meta-analyses, systematic reviews of RCTs or RCTs with a high risk of bia High quality systematic reviews of casecontrol or cohort studies; high-quality case control or cohort studies with a very low risk of confounding, bias or chance and a high probability that the relationship is casual Well-conducted case-control or cohort studies with a low risk of confounding, bias or chance and a moderate probability that the relationship is causal Case-control or cohort studies with a high risk of confounding, bias or chance and a significant risk that the relationship is not causal Non-analytical studies (for example case reports, case series) Expert opinion, formal consensus Levels of evidence for the studies of the accuracy of diagnostic tests Level Type of evidence Ia Ib II III IV Systematic reviews (with homogeneity)a of level-1 studiesb Level-1 studiesb Level-2 studiesc; systematic reviews of level-2 studies Level-3 studiesd; systematic reviews of level-3 studies Consensus, expert committee reports or opinions and/or clinical experience without explicit critical appraisal; or based on physiology, bench research or ‘first principles’ a Homogeneity means there are no or minor variations in the directions and degrees of results between individual studies that are included in the systematic review. b Level-1 studies are studies that use a blind comparison of the test with a validated reference standard (gold standard) in a sample of patients that reflects the population to whom the test would apply. c Level-2 studies are studies that have only one of the following: • narrow population (the sample does not reflect the population to whom the test would apply) • use a poor reference standard (defined as that where the ‘test’ is included in the ‘reference’, or where the ‘testing’ affects the ‘reference’) • the comparison between the test and reference standard is not blind • case-control studies d Level-3 studies are studies that have at least tow or three of the features listed above Eczema Index of Drugs/Drug Classes mentioned in the Guideline This index is not part of the guideline.
