Paediatric Allergy Clinical Network
Purpose of the network
Our purpose is to promote and support evidence based best practice for those involved in the health care of New Zealand children and young people with allergies, across community, primary and secondary care. This includes a focus on quality improvement to make sure there is equal access to care and resources.
The network will work to achieve this through:
Encouraging development of services
Improving access to existing resources
Generating guidelines
Enhancing workforce education
Allergies affect over 20% of New Zealand children, and often begin in infancy with the development of food allergy. The burden of allergies on both children and their families can be significant. Early diagnosis and appropriate clinical management can minimise the long-term impact on quality of life for these children and their families.
The contents of the following pages include guidelines as well as links to information, resources and training for health professionals; and resources such as information handouts for families. Some links are to overseas websites which have been approved by the Allergy Clinical Network (CN) as providing valuable information relevant to New Zealand health professionals. Where necessary the Allergy CN will develop guidelines and resources specific to New Zealand.
The Allergy CN has produced the following guidelines:

NEW: Food Protein Induced Enterocolitis Syndrome (FPIES)
Food protein-induced enterocolitis syndrome (FPIES) is an adverse food reaction involving the immune system that mainly affects infants and young children. It is caused by an allergic reaction to one or more ingested foods which results in inflammation of the small and large intestine.
See Food protein induced enterocolitis syndrome (FPIES) - Australasian Society of Clinical Immunology and Allergy (ASCIA) for more information and the ASCIA FPIES Action Plan
Anaphylaxis
Anaphylaxis is the most severe form of allergic reaction, usually occurring within 20 minutes of exposure to the trigger, and is potentially life threatening.
It must be treated as a medical emergency, with the administration of intramuscular adrenaline as the first line treatment.
The most common trigger in infants, children and young people is food allergy; other triggers include allergy to insect venom (bee or wasp), drugs (e.g. penicillin), and latex.
Definition
Any acute onset illness with typical skin features (urticarial rash or erythema/flushing, and/or angioedema), PLUS involvement of respiratory and/or cardiovascular and/or persistent severe gastrointestinal symptoms.
OR
Any acute onset of hypotension or bronchospasm or upper airway obstruction where anaphylaxis is considered possible, even if typical skin features are not present. (ASCIA)
Signs and symptoms that an allergic reaction is anaphylaxis include:
| Respiratory | Difficulty/noisy breathing Swelling of tongue Swelling/tightness in throat Difficulty talking and/or hoarse voice Wheeze or persistent cough |
| Cardiovascular | Loss of consciousness Collapse Palor and floppiness (in young children) Hypotension |
Acute management
There is a Starship Clinical Guideline on the Management and Treatment of Anaphylaxis.
The New Zealand and Australian Resuscitation Councils published guidelines for First Aid Management of Anaphylaxis in 2016: https://www.resus.org.nz/assets/Uploads/ANZCOR-Guideline-9-2-7-Anaphylaxis-Aug16.pdf
Long term management
Long-term management of anaphylaxis includes:
Confirmation of triggering allergens
Allergen avoidance measures
Prescription for adrenaline auto-injector
Provision of Anaphylaxis Action Plan
Identification of risk factors
Patient education on all of the above
Venom immunotherapy/drug desensitisation if relevant.
For infants, children and young people who have had anaphylaxis, referral should be made to the local Paediatric Outpatient Service (or Paediatric Allergy/Immunology Service if available). Refer to Ongoing care of children and young people with food allergy for further information.
In the interim, General Practitioners (GPs) should ensure the family has been provided with an Anaphylaxis Action Plan and adrenaline autoinjector ordering information. EpiPen®s are currently the only adrenaline auto-injector available in New Zealand and are funded by PHARMAC.
More information is available from Allergy New Zealand
Adrenaline autoinjectors
Be mindful that autoinjectors come in different doses. Recommendations from ASCIA (Australasian Society for Clinical Immunology & Allergy) are as follows:
EpiPen® Adult for children >20kg (package insert says over 30kg)
Epipen® Jnr for children 7.5-20kg (package insert says 15-30kg)
Recommendation of an EpiPen® to a child weighing <10kg should be discussed with senior medical staff
An EpiPen® is appropriate for those:
with anaphylaxis to non-avoidable triggers eg. bee stings and most food
with less severe allergic reaction (i.e. not anaphylaxis) but with other risk factors for anaphylaxis eg. asthma, living in remote locations, peanut or tree nut allergy. This decision can generally be made at the Outpatient Clinic.
See information sheet on Adrenaline autoinjector ordering
Action plans
Individual Anaphylaxis Action Plan forms are available from the ASCIA website: http://www.allergy.org.au/health-professionals/anaphylaxis-resources/ascia-action-plan-for-anaphylaxis. There is a separate version for Allergic Reactions (personal) for use when no adrenaline autoinjector has been prescribed. The patient's details, other medications to be used etc should be filled in online, printed and then signed and dated by the prescribing doctor.
Patient/family education
GPs should ensure that family/carers know when and how to use an auto-injector. Free training pens are available from www.epiclub.co.nz. Families should also be encouraged to register in order to receive their own trainer pen, and reminders when their EpiPen® is due to expire. There is also a free e-anaphylaxis training module for carers/community on the ASCIA website.

Allergy prevention
The Allergy Clinical Network supports the guidelines on Infant Feeding and Allergy Prevention published by the Australasian Society of Clinical Immunology and Allergy (ASCIA). First published in 2016, they have been updated to reflect further evidence in relation to the early introduction of food, and optimising eczema management. These guidelines are relevant for all families, including those in which siblings or parents already have food allergies or other allergic conditions.
The reasons for the continued rise in allergic diseases, such as food allergy, eczema, asthma and allergic rhinitis (hay fever) are complex and not well understood. Although infants with a family history of allergic disease are at higher risk of allergies, infants with no family history can also develop allergies.
Risk factors identified for the development of food allergies¹:
An infant with an immediate family history (first degree relative) of allergies, is considered at increased risk of developing food allergy.
Severe eczema, defined as persistent or frequently recurring eczema with typical morphology and distribution, assessed as severe by a healthcare professional and requiring frequent prescription-strength topical corticosteroids, calcineurin inhibitors or other anti-inflammatory agents, despite appropriate use of emollients
Infants with severe eczema and/or egg allergy are at increased risk of developing peanut allergy. Introduction of peanut before 12 months of age in these infants significantly reduces the risk of
developing peanut allergy³,⁴.
If an infant already has an allergic disease (such as severe eczema or food allergy), it is recommended parents discuss what specific measures might be useful with their doctor.
