Effects of an adjunctive treatment with Bacillus subtilis for food allergy.

The authors evaluated the clinical efficacy of an adjunctive treatment with spores of Bacillus subtilis in 20 adult patients with urticaria-angioedema syndrome from food allergy. The patients treated with B. subtilis showed a significant reduction in frequency and severity of clinical features in respect to the patients who received no treatment. Bacillus subtilis spores may increase S-IgA synthesis or protect gastroenteric mucosa.
