Abstract

– OBJECTIVE: Nasal administration of Streptococcus salivarius 24SMB and Streptococcus oralis 89a has been proposed to reduce the risk of new episodes of adenoiditis, tonsillitis and acute rhinosinusitis in children. PATIENTS AND METHODS: We enrolled 202 children with a recent diagnosis of recurrent upper respiratory tract infection. All the patients were treated twice daily for 7 days each month for 3 consecutive months with a nasal spray whose active agents were two specific bacterial strains: Streptococcus salivarius 24SMB and Streptococcus oralis 89a. Evaluation was performed at the end of treatment and at follow-up at 3, 6, and 12 months. RESULTS: Patients who completed the entire 90-day course of bacteriotherapy and the follow-up period showed a 64.3% reduction in their episodes of upper respiratory tract infections compared to the number of episodes recorded in the previous year. Treatment decreased the reported incidence of infection events by 52.4% in the first 3 months, 31.2% at 6-month follow-up, and 20.8% after 12 months. Enrolled patients tolerated the product well, and there were no dropouts. CONCLUSIONS: Prophylactic bacteriotherapy by administration of Streptococcus salivarius 24SMB and Streptococcus oralis 89a in children with a history of recurrent upper respiratory tract infection could reduce the number of episodes of otolaryngologic infections. Bacteriother-apy can be even more clinically important due to increasing difficulty in finding new effective antibiotic compounds. New alternative therapeutic approaches must be found with, in comparison to antibiotics, greater specificity and safety with respect to patients’ native beneficial flora; lack of drug interactions; the ability to leverage complementary systemic modes of action; and drastically reduced risk of developing resistance within the patient population and the environment.
