II. Epidemiology

  1. More common in Hawaii and California

    1. Scombridae family or dark meat fish such as Tuna, Mahi-mahi,or mackerel
    2. Food typically tastes atypical
  2. Histidine from fish muscle is decarboxylated to histamine by marine Bacteria
    1. Bacteria containing histidine decarboxylase include Escherichia, Klebsiella, Proteus, Vibrio, pseudomonas
  3. Isoniazid potentiates this reaction

IV. Symptoms (Related to histamine release)

  1. Typical histamine related response
    1. Severe Flushing including facial Flushing
    2. Diarrhea
    3. Palpitations
    4. Abdominal Pain
    5. Urticaria
    6. Bronchospasm with Wheezing
    7. Orthostatic Hypotension
  2. Histamine-3 (H3) activity related symptoms
    1. Nausea
    2. Vomiting
    3. Severe Headache

V. Labs

  1. Avoid histamine level (not useful)
  2. Tryptase level
    1. May differentiate from Allergic Reactions

VI. Differential Diagnosis

VII. Course

  1. Onset within 10-60 min (on average 20-30 min) of ingestion
  2. Resolves within 6-8 hours, up to 24 hours (rarely more)

VIII. Management

  1. Avoid Gastric Decontamination in most cases
  2. Antihistamine
    1. Diphenhydramine (Benadryl) 50 mg IV/IM}PO
    2. Consider H2 Receptor Blocker (Ranitidine, Cimetidine)
  3. Nebulized Albuterol
    1. Indicated for bronchospasm
  4. Other symptomatic management
    1. Antiemetics
