Inflammatory non-allergic rhinitis (INAR) is characterized by the presence of an inflammatory infiltrate and a non-IgE-mediated pathogenesis. This retrospective, controlled, multicentre study investigated whether a symbiotic, containing Lactobacillus acidophilus NCFM, Bifidobacterium lactis, and fructo-oligosaccharides (Pollagen®, Allergy Therapeutics, Italy), prescribed as adjunctive therapy to a standard pharmacological treatment, was able to reduce symptom severity, endoscopic features, and nasal cytology in 93 patients (49 males and 44 females, mean age 36.3±7.1 years) with INAR. The patients were treated with nasalcorticosteroid, oral antihistamine, and isotonic saline. At randomization, 52 patients were treated also with symbiotic as adjunctive therapy, whereas the remaining 41 patients served as controls. Treatment lasted for 4 weeks. Patients were visited at baseline, after treatment, and after 4-week follow-up. Adjunctive symbiotic treatment significantly reduced the percentages of patients with symptoms and endoscopic signs, and diminished inflammatory cells. In conclusion, the present study demonstrates that a symbiotic was able, as adjuvant treatment, to significantly improve symptoms, endoscopicfeature, and cytology in patients with INAR, and its effect may be long lasting.
