Follow-up of issues raised by Marie-Alexandra Lambot

Discussion centered around whether Pseudoallergy to sulfite food preservatives was required as the creation of a structural + role based grouper is not likely to be supported. It was noted that sulfites are are already under food preservative in SNOMED CT. A question arose as to whether not only are sulfites preservatives for non-food substances but whether pseudoallergic reactions to these have been reported. Marie-Alexandra Lambot will research this further with her allergy colleagues. The group on the whole felt that Pseudoallergy to sulfite would suffice.

Recommendation from Jim Case and ECE project group to obtain buy-in from this CRG in order to expedite proposed changes

• Review of existing model and proposed changes
• Briefing paper for end users

• Group generally agreed with proposed changes to concept model with the possible exception of moving the condition and disposition classes under clinical findings
• Bruce Goldberg will discuss further with head of terminology

• Discussion centered around definitions and relationship of Nonallergic hypersensitivity, pseudoallergy and intolerance:
  • Is pseudoallergy really obsolete or is it a more specific type of nonallergic hypersensitivity?
  • Are intolerance and nonallergic hypersensitivity the same or is intolerance a more general grouper encompassing both allergy and pseudoallery or is intolerance a subtype of hypersensitivity or nonallergic hypersensitivity?
• Bruce Goldberg to prepare diagrams illustration possible hierarchical relations of the above concepts for review during the next call
