  • Key issue is that if may contain foods have caused anaphylaxis
  • MMR grown in chick embryoFlu vaccine residual amounts of egg proteins (≤ 1 mcg ovalbumin) Abidec contains peanut oil, deproteinated-no riskClarityn contains lactoseSingulair 10mg film coated contains lactose not paediatric 4mg chewable/oral granules 5mg chewable do not.
  • Raw versus boiled peanutsFrying or boiling peanuts, as practiced in China, appear to reduce the allergenicity of peanuts compared with the method of dry roasting IgE binding to Ara h 2 and Ara h 3 
  • Maria Said Anaphylaxis AustraliaWorldwide huge complex issue
  • Cannot eliminate all risk, have to manage itNo truly allergy free environment despite detergents, hot waterIn cases of anaphylaxis resulting from a food avoided need to think outside the box
  • Transcript

    • 1. Food Allergy

      what foods are likely to contain trigger foods.
      clinically relevant cross-reactivities and co-reactivities
      appropriate nutritional requirements for children at different ages
      signs and symptoms of faltering growth
      Be able to:
      advise on appropriate dietary exclusion and alternatives including practical, individualised cultural and age appropriate advice

    • 9. Label reading and ingredient interpretation : every label every time
      Food & drink
      Hand cream
    • 10. Food labelling issues
      No legal requirement to provide precautionary statement. Where provided: no criteria.
      Allergen thresholds
      Raw versus cooked:
      what temperature & for how long
      Frying, boil, roast  
      Allergen in SPT assays versus food
    • 11. EAACI Food Allergy & Anaphylaxis Meeting February 2011
      Food Allergy & Anaphylaxis Alliance FAAA
      Criteria for use of precautionary statements
      Major allergens declared
      Simple language clear terms
      Consumer communication
      European Federation of Allergy & Airways Disease EFA
      Packaged and non packaged foods
      Abolish precautionary labelling
      Establish thresholds ( Taylor et al. Clin Exp Allergy. 34(5):689-95, 2004; Moneret-Vautrin. Curr Opin Allergy Clin Immunol. 2004 Jun;4(3):215-9) Working groups:ILSI Europe, Europrevall, CONGEN etc
      “ No label-no eat, no adrenalin – no eat”
    • 12. Cross reactivities
      Sicherer, JACI December 2001.

      “May contain traces of.....”
      not for those at risk of anaphylaxis

    • 18. Faltering growth & food allergy
      Failure to grow at the expected rate:
      Height and weight velocity are the most
      sensitive indicators that energy
      requirements are being met
      Inappropriately restricted diets
      Associated asthma, chronic skin infections
      Appropriate centile reference charts
    • 19. Poor parallel centiles - centile position falls, continued growth parallel to the 0.4 centile for weight and height. This occurs when children adapt to the abnormal situation of poor nutrition and the situation becomes chronic.
      Height and weight centiles markedly discrepant -where discrepancies in the centile ranking occur . Most children will have weight centile no more than 1 -2 centile spaces below their height.
      Family pattern discrepant - marked discrepancies from the parents and other family members attained height centiles.
      Retrospective rise - improvement in the child's centile position when nutrition is improved.
      Saw tooth - dipping. Weight goes up and down, crossing and recrossing centile positions.
