Conclusions The current evidence is not sufficiently strong to verify a preventive role of probiotics in AR , but probiotics may improve the overall quality of life and nasal symptom scores .
Background Allergic rhinitis ( AR ) is a disease of respiratory allergy , and probiotics can provide a potential strategy for its management .
The purpose of this study was to carry out a systematic review to investigate the role of probiotics in the prevention and treatment of AR .
Randomized placebo-controlled trial of lactobacillus on asthmatic children with allergic rhinitis.
Previous studies have suggested that probiotic administration may have therapeutic and /or preventive effects on atopic dermatitis in infants ; however , its role in allergic airway diseases remains controversial . To determine whether daily supplementation with specific Lactobacillus gasseri A5 for 8 weeks can improve the clinical symptoms and immunoregulatory changes in school children suffering from asthma and allergic rhinitis ( AR ) . We conducted a r and omized , double-blind , placebo-controlled study on school children ( age , 6 - 12 years ) with asthma and AR . The eligible study subjects received either L. gasseri A5 ( n = 49 ) or a placebo ( n = 56 ) daily for 2 months . Pulmonary function tests were performed , and the clinical severity of asthma and AR was evaluated by the attending physicians in the study period . Diary cards with records of the day- and nighttime peak expiratory flow rates ( PEFR ) , symptoms of asthma , and AR scores of the patients were used for measuring the outcome of the treatment . Immunological parameters such as the total IgE and cytokine production by the peripheral blood mononuclear cells ( P BMC s ) were determined before and after the probiotic treatments . Our results showed the pulmonary function and PEFR increased significantly , and the clinical symptom scores for asthma and AR decreased in the probiotic-treated patients as compared to the controls . Further , there was a significant reduction in the TNF-α , IFN-γ , IL-12 , and IL-13 production by the P BMC s following the probiotic treatment . In conclusion , probiotic supplementation may have clinical benefits for school children suffering from allergic airway diseases such as asthma and AR
