Local Bacteriotherapy - a promising preventive tool in recurrent respiratory infections.

INTRODUCTION: Children with recurrent respiratory infections (RRI) represent a social issue for the economic burden and the negative family impact. Local Bacteriotherapy is an attractive therapeutic strategy that could be potentially effective in preventing infections. The current article remarks on the existing evidence of preventing RRI by Local Bacteriotherapy. AREAS COVERED: The literature search methodology was based on the articles cited by PubMed from 1980 to 2020. Respiratory infections include rhino-pharyngitis, otitis media, rhinosinusitis, pharyngo-tracheitis, bronchitis, and pneumonia. Several studies were performed to investigate the effects of Local Bacteriotherapy in children with RRI. Both intranasal and oral Local Bacteriotherapy were evaluated. The findings showed that Local Bacteriotherapy significantly reduced the number of RI episodes, their severity, the use of antibiotics, and school absences. EXPERT OPINION: Local Bacteriotherapy is a promising approach to RRI prevention and could be a profitable strategy to contrast infections in the future.

An International Survey on the pragmatic management of epistaxis.

Epistaxis is one of the most common ear, nose and throat emergencies. The management of epistaxis has evolved significantly in recent years, including the use of nasal cautery and packs. However, a correct treatment requires the knowledge of nasal anatomy, potential risks, and complications of treatment. Epistaxis is often a simple and readily treatable condition, even though a significant bleed may have potentially severe consequences. At present, there are very few guidelines concerning this topic. The current Survey explored the pragmatic approach in managing epistaxis. A questionnaire, including 7 practical questions has been used. The current International Survey on epistaxis management reported a relevant prevalence (21.7%), mainly during childhood and senescence, an important hospitalization rate (11.8%), the common use of anterior packing and electrocoagulation, and the popular prescription of a vitamin supplement and intranasal creams.

Chronic rhinosinusitis with nasal polyposis: the role of personalized and integrated medicine.

Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a frequent disorder. From a clinical and an immunopathological point of view, different phenotypes and endotypes have been identified. The frequent comorbidity with asthma allowed to pave the way to the use of biological agents for the treatment of CRSwNP. Biological agents are targeted to antagonize IgE, interleukin (IL) 4, IL-5, and IL-13 at present. However, a correct and appropriate workup is mandatory, mainly concerning the exact definition of the specific pheno-endotype. The preliminary outcomes are promising, even though there is a need for well-established indications, criteria of responsiveness, duration, and safety. On the other hand, this personalized medicine could be fruitfully integrated with gold-standard medications, such as intranasal corticosteroids. As CRSwNP is a chronic disorder, treatment should be long-lasting, so complementary anti-inflammatory treatments could be opportunely integrated and/or alternated to steroids.

Oral bacteriotherapy in children with recurrent respiratory infections: a real-life study.

Children with recurrent respiratory infections (RRI) represent a social issue for the economic burden and the familiar negative impact. Bacteriotherapy, such as the administration of "good" bacteria, is a new therapeutic strategy that could be potentially effective in preventing infections. The current study tested the hypothesis of preventing RRI by oral Bacteriotherapy in a real-life setting. This open study was conducted in an outpatient clinic, enrolling 51 children (27 males, mean age 4.8 ± 2.6 years) suffering from RRI. Children were treated with an oral spray, containing Streptococcus salivarius 24SMB and Streptococcus oralis89a (125 x 109 CFU/g), 2 puffs per os once/day for 30 consecutive days; this course was repeated for 3 months. The evaluated parameters were: RI number and school absences reported in the current year; these outcomes were compared with those recorded in the past year. The mean number of RI significantly diminished: from 5.17 (2.30) in the past year to 2.25 (2.43) after the treatment (p<0.0001). The mean number of school absences significantly diminished (from 3.35 to 1.86; p<0.0001). In conclusion, this real-life study suggests that oral Bacteriotherapy with Streptococcus salivarius 24SMB and Streptococcus oralis89a could efficaciously and safely prevent RRI in children.

Preventing recurrent acute otitis media with Streptococcus salivarius 24SMB and Streptococcus oralis 89a five months intermittent treatment: An observational prospective cohort study.

INTRODUCTION: Acute otitis media (AOM) is the most common childhood disease leading to antibiotic use. More than 80% of children under three years of age experience at least one episode, and about one-third of these report significant recurrence of episodes. In recent years, several studies reported that normal nasopharyngeal flora inhibits growth of common otopathogens, suggesting that maintenance of an "adequate" nasopharyngeal flora might prevent occurrence of upper respiratory tract infections, including AOM. This study aims to determine whether five-month treatment with Streptococcus salivarius 24SMB and Streptococcus oralis 89a nasal spray prevents recurrence of AOM and prescription of antibiotics in children with diagnosis of recurrent AOM. METHODS: Observational prospective cohort study including children aged 1-6 years with diagnosis of recurrent AOM registered with 31 Italian family pediatricians. 81 children were enrolled in the study from September 2016 to the end of the five therapeutic cycles of the Streptococcus salivarius 24SMB and Streptococcus oralis 89a supplied 7 days each month for 5 consecutive months. For each treated child, one untreated control was randomly selected, 1:1 matched for gender, age, and follow-up. RESULTS: 158 children (79 treated and 70 untreated) were included into the analysis (mean age, 3.9 years; 47% female). Univariate analysis showed a statistically significant 34% (95% CI 1%-56%) reduction in number of AOM episodes in treated children compared with those not treated. Significantly fewer antibiotics were dispensed among treated children (24%, 95% CI 1%-41%). CONCLUSIONS: Our findings suggest that intermittent treatment of children with diagnosis of recurrent AOM with nasal spray containing Streptococcus salivarius 24SMB and Streptococcus oralis 89a for a period of five months might be effective in preventing antibiotic use associated with recurrent episodes of AOM. Additional larger studies to address this important clinical problem are recommended.
