Summary

Food sensitivity may trigger recurrent aphthous ulceration (RAU) in patients unresponsive to vitamin therapy. Allergy testing identified triggers in most patients, with avoidance leading to significant symptom improvement.

Area of Science:

  • Immunology
  • Dermatology
  • Allergology

Background:

  • Recurrent aphthous ulceration (RAU) affects numerous patients, often without a clear cause.
  • Standard treatments, including vitamin B1 and B6, are ineffective for some RAU patients.
  • Hematological normality is common in RAU patients, necessitating exploration of other etiologies.

Purpose of the Study:

  • To investigate the role of food sensitivity and other allergies as potential causes of recurrent aphthous ulceration (RAU).
  • To assess the efficacy of allergen avoidance in managing RAU symptoms in a clinical setting.

Main Methods:

  • A cohort of 40 patients with RAU, who were hematologically normal and unresponsive to vitamin therapy, was studied.
  • Patch testing using the Standard European Series was performed on 21 patients.

  • Patients received professional advice on allergen avoidance based on test results.

    • Main Results:

    • Twenty out of 21 tested patients exhibited positive reactions to clinically relevant substances.
    • Eighteen patients reported significant improvement in their RAU symptoms after avoiding identified allergens.
    • No significant improvement was observed in patients who did not respond to vitamin therapy.

    Conclusions:

    • Food sensitivity and other allergies are significant potential etiologic factors in recurrent aphthous ulceration (RAU).
    • Allergen identification and avoidance can be an effective management strategy for RAU in susceptible individuals.
    • Further research into immunological mechanisms underlying RAU is warranted.
