Flaxseed hypersensitivity is rare but possible. This case study highlights anaphylaxis from ingesting flax (Linum usitatissimum) seeds, emphasizing the need for awareness in food allergies.

Area of Science:

  • Food allergy research
  • Clinical immunology
  • Allergen identification

Background:

  • Flax (Linum usitatissimum) seeds are common food ingredients and laxatives.
  • Hypersensitivity reactions to flaxseeds are infrequently reported.
  • Growing use of flaxseeds in health foods necessitates allergy awareness.

Observation:

  • A 39-year-old woman experienced anaphylaxis after consuming linseed.
  • The patient presented with multisystemic allergic symptoms.
  • Diagnostic tests confirmed a type I hypersensitivity reaction.

Findings:

  • Positive skin prick tests and histamine release assays with linseed extracts.
  • Detection of linum-specific IgE antibodies in patient serum via ImmunoCAP assay.

  • Confirmed type I hypersensitivity to flaxseed.

    • Implications:

    • Flaxseeds can be an allergen, causing severe reactions like anaphylaxis.
    • Healthcare providers should consider flaxseed allergy in differential diagnoses.
    • Increased availability of flaxseeds warrants vigilance for potential allergic sensitization.
