Managing children with frequent respiratory infections and associated wheezing: a preliminary randomized study with a new multicomponent nasal spray.

BACKGROUND: Preschoolers frequently have respiratory infections (RIs), which may cause wheezing in some subjects. Type 2 polarization may favor increased susceptibility to RIs and associated wheezing. Non-pharmacological remedies are garnering increasing interest as possible add-on therapies. The present preliminary study investigated the efficacy and safety of a new multi-component nasal spray in preschoolers with frequent RIs and associated wheezing. METHODS: Some preschoolers with these characteristics randomly took this product, containing lactoferrin, dipotassium glycyrrhizinate, carboxymethyl-beta-glucan, and vitamins C and D3 (Saflovir), two sprays per nostril twice daily for 3 months. Other children were randomly treated only with standard therapy. Outcomes included the number of RIs and wheezing episodes, use of medications, and severity of clinical manifestations. RESULTS: Preschoolers treated add-on with this multicomponent product experienced fewer RIs and used fewer beta-2 agonists than untreated children (P = 0.01 and 0.029, respectively). CONCLUSIONS: This preliminary study demonstrated that a multicomponent product, administered add-on as a nasal spray, could reduce the incidence of RIs and use of symptomatic drugs for relieving wheezing in children.

A combined treatment for patients with dry eye and associated laryngopharyngeal reflux: a real-life approach.

AIM: To evaluate the efficacy and tolerability of administering a combined therapy in patients with dry eye syndrome (DES) and associated laryngopharyngeal reflux (LPR). METHODS: The study was retrospective, open, observational, and conducted in a real-life setting. Patients had pathological symptom assessment in dry eye (SANDE) and reflux symptom index (RSI) at baseline. Patients were re-assessed after 1mo and at the end of treatment. The treatment consisted of a three-month course based on the combined therapy: Gastroftal eye drops, one drop three times a day, and Gastroftal tablets, two tablets after lunch and two tablets after dinner. Tear break-up-time (TBUT) test, Schirmer test, RSI, and SANDE questionnaire were evaluated. RESULTS: The study included 253 patients. The mean age was 58±11.19y. TBUT test score and Schirmer's test significantly increased (both P<0.001) after 1mo and at the end of treatment. The RSI score and SANDE scores significantly decreased (both P<0.001) after 1mo and at the end of treatment. CONCLUSION: The current, retrospective, and open study shows that combined therapy using Gastroftal eye drops and tablets could represent a valuable option in managing patients with DES associated with LPR.

HMGB1-antagonism exerted by glycyrrhizin could be fruitful against COVID-19.

The COVID-19 pandemic era is causing a relevant issue for the health. There is no specific drug able to antagonize the SARS-CoV-2 infection. As a consequence, there is growing interest about potential molecules able to contrast infection. In this regard, HMGB, an alarmin, may play a relevant role in pathogenic mechanisms induced by SARS-CoV-2.  As HMGB1 is antagonized by glycyrrhizin, this substance could be potentially useful as ancillary treatment in COVID-19.

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.

HMGB1 in nasal inflammatory diseases: a reappraisal 30 years after its discovery.

INTRODUCTION: High mobility group protein box 1 (HMGB1) is a protein belonging to the alarmin family. HMGB1 has a relevant role in starting the inflammatory cascade by means of receptors, such as RAGE and TLR. HMGB1 supports transcription of many genes in interactions with many transcription factors, including NF-kB. The axis HMGB1-RAGE-NF-kB has, therefore, a pivotal role in the inflammatory cascade. HMGB1 controls the production of several pro-inflammatory cytokines and the proliferation and activation of many inflammatory cells. AREAS COVERED: The present report concerns the role of HMGB1 in nasal inflammatory disorders, including allergic and non-allergic rhinitis, and chronic rhinosinusitis with nasal polyps. HMGB1 modulation has been the aim of several studies. The literature search included recent papers that covered this topic. EXPERT OPINION: As HMGB1 has a pivotal role in inflammatory events, its modulation could be attractive for designing new therapeutic strategies. In this regard, glycyrrhetic acid (GA), the active component of Glycyrrhiza glabra, can efficiently block HMGB1. Promising reports seem to suggest that GA could exert favorable anti-inflammatory activity in patients with nasal inflammatory disorders.

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.

The impact of allergic rhinitis in clinical practice: an Italian Survey.

Allergic rhinitis (AR) is a very common disorder. The current Survey was conducted on a sample of about 5,000 adult subjects in 5 Italian cities. A questionnaire, containing 15 questions, was administered on the road. AR affects about 20% of the general population. The most common diagnostic test was the skin prick test, but only 12% of patients performed an allergy test to confirm the diagnosis. About 50% of patients did not take any medicine. Even about 40% of treatments were suggested by friends or pharmacists. In conclusion, the current Survey demonstrated that AR is a common disorder in Italy, the diagnostic work-up is still incorrect, and the therapeutic approach does not adhere to the guidelines. Therefore, there is a need to implement adequate information on this topic in Italy.

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.

The impact of rhinosinusitis in clinical practice: an Italian Survey.

Rhinosinusitis is a common disease that is classified in acute (ARS) and chronic (CRS). The current Survey was conducted on a sample of about 5,000 adult subjects in 5 Italian cities. A questionnaire, containing 15 questions, was administered on the road. RS affects about 20% of the general population. The most common diagnostic test was the skull x-ray. Antibiotics were the most frequently prescribed therapy. In conclusion, the current Survey demonstrated that RS is a common disorder in Italy, the diagnostic work-up is still incorrect, and the therapeutic approach does not adhere to the guidelines. Therefore, there is a need to implement adequate information on this topic in Italy.

A new therapeutic approach for the Dry Eye Syndrome in patients with laryngopharyngeal reflux: first data.

Laryngopharyngeal reflux (LPR) is a common disorder. Pepsin has been detected also at eye level, this was a starting point for newest theories about LPR impact on Dry Eye Syndrome. The current preliminary study compared two treatments in patients with Dry Eye Syndrome and LPR. Patients were treated with Gastroftal eye drops and Gastroftal tablets or hyaluronic acid eye drops for 3 months. The following parameters were evaluated: Ocular Surface Disease Index (OSDI), OSDI categories, Reflux Symptom Index (RSI), Reflux Finding Score (RFS), Fluorescein Tear Breakup Time (B-TUT), and Schirmer test before and after treatment. On the whole, 21 patients were enrolled: 10 were treated with hyaluronic acid Atlantis (Group A) and 11 with Gastroftal eye drops and tablets (Group B). After treatment, in Group A only OSDI significantly diminished (p=0.029); in Group B there were significant reductions concerning OSDI (p=0.0277), OSDI categories (p=0.0211), RSI (p=0.0172), Schirmer test (p=0.0172), T-BUT (p=0.0265), and RFS (p=0.0205). The current preliminary demonstrated that the combined ocular and systemic therapy with hyaluronic acid, Magnesium alginate, Simethicone, and Camelia sinensis may be considered a promising treatment in patients with Dry Eye Syndrome due to LPR.

A comparison between mometasone furoate nasal spray and intranasal glycyrrhetic acid in patients with allergic rhinitis: a preliminary study in clinical practice.

Allergic rhinitis (AR) is caused by an IgE-mediated inflammatory reaction consequent to the exposure to the causal allergen. Glycyrrhetic acid (GlyAc) is a natural compound extracted from the liquorice that exerts anti-inflammatory activity. This real-life study compared intranasal GlyAc, present in a medical device containing also glycerol and mannitol, with mometasone furoate nasal spray (MFNS) in 50 adult outpatients with AR. Both treatments lasted 2 months. Endoscopic signs, perception of symptom severity, assessed by VAS, and nasal function measured by rhinomanometry were evaluated at baseline (T0), after one (T1) and two (T2) months. The intergroup analysis showed that at T1 there was no significant difference between groups about the use of decongestants and antihistamines, turbinate hypertrophy and pale mucosa, perception of olfaction and snoring. At T2 there was no significant difference between groups about use of relievers, all endoscopic signs, and perception of nasal discomfort, nasal obstruction, olfaction, and snoring. The intragroup analysis showed that in MFNS group there was a significant change during the entire period of treatment for all parameters except watery rhinorrhea (sign) and ocular discomfort; in GlyAc group there was a significant change during the entire period of treatment for all parameters. In conclusion, this preliminary study, conducted in clinical practice, evidenced that intranasal CysAC plus mannitol was able to significantly improve nasal endoscopic signs, perception of symptoms, and nasal function in patients with AR. Therefore, GlyAc could be a reasonable therapeutic option to control allergic inflammation.

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.

Tonsil volume may predict adenoid size: a real-life study.

Tonsil hypertrophy (TH) and adenoid hypertrophy (AH) are very common in children. Adenoid is visible only by endoscopy. This study investigated the possible relationship between the tonsil and adenoid volume and the possible prediction of adenoid size. Globally, 991 children (461 females, 530 males, mean age 6.2 ± 2.3 years), complaining persistent upper airway obstruction, were consecutively visited at an otorhinolaryngological unit. TH was significantly (p<0.0001) associated with AH and tonsil volume predicted adenoid size. This outcome could have relevance in clinical practice as adenoid are evaluable only by endoscopy, so tonsil assessment could mirror adenoid volume.

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.

Eye reflux: an ocular extraesophageal manifestation of gastric reflux.

AIM: To suspect laryngopharyngeal reflux (LPR) in patients with ocular surface disease (OSD). METHODS: The present study evaluated a group of subjects with OSD assessing the Ocular Surface Disease Index (OSDI) and the Reflux Symptom Index (RSI) to detect patients with suspected LPR and define a possible relationship between tests. RESULTS: Two hundred and ninety subjects (175 females, mean age: 60.41±15.68y) were consecutively visited at ophthalmologist offices. One hundred and one (34%) patients had pathological RSI (>13) and consequently a suspected LPR. CONCLUSION: The current study shows that suspected LPR may be common (34%) in patients with OSD and a suspected LPR may be considered in OSD patients when RSI score is >13 and OSDI score is >42.

Allergic Rhinitis in Children: A Randomized Clinical Trial Targeted at Symptoms.

Allergic rhinitis (AR) underlies many symptoms and complications which severely affect children's quality of life. This two-arm study aimed at evaluate the efficacy and safety of the medical device Narivent(®) versus topical corticosteroids in the symptomatic management of allergic rhinitis in paediatric patients. A randomized study was conducted. Forty subjects with a diagnosis of allergic rhinitis were randomized to receive one puff of Narivent(®) into each nostril twice daily for 30 days (n = 20) or to receive one puff of topical intranasal corticosteroid into each nostril twice daily for 30 days (n = 20). In both treatment arms, severity of major symptoms related to AR, including nasal congestion, rhinorrhoea, sneezing and nasal itching, was assessed subjectively on a 0-100 mm visual analogue scale. Nasal congestion, rhinorrhoea and sneezing improved significantly after 30 days of treatment with Narivent(®). Similarly, in topical steroids group severity of all subjective symptoms decreased significantly. Narivent(®) appears to be efficacious in treating nasal congestion and other major symptoms in children with AR over a 30-day period, showing comparable results to intranasal corticosteroids therapy but with a better safety profile.

Well and intermediate differentiated laryngeal chondrosarcoma: toward conservative surgery?

Chondrosarcoma of the larynx is a relatively rare malignant tumor. In the world literature, only 600 cases of laryngeal chondrosarcoma (LCS) have been reported. It is the most frequent non-epithelial tumor of the larynx (0.07-2% of all cancers), usually occurring on the cricoid. We present six cases of well-intermediate differentiated grade chondrosarcoma of the larynx, diagnosed between the fifth and seventh decades of life, in the absence of relevant risk factors. All cases were subjected to a conservative surgical approach, either endoscopic using remodeling transoral laser surgery, or open neck via a supratracheal partial laryngectomy (STL), sparing laryngeal function. All patients are free from recurrence with a minimum follow-up of 31 months. All were ultimately decannulated, are able to tolerate a quite normal diet and to speak satisfactorily. Conservative laryngeal surgery is effective because chondrosarcoma is often a low-grade tumor showing slow growth. The criteria for choosing the type of surgery was based on the age of the patient (elderly patient > favoring an endoscopic approach), on the rate of involvement of the cricoid and on the involvement of the cricoarytenoid joints (if possible to save a cricoarytenoid unit > favoring a STL). By extending the inferior limit of the resection to include a large part of the cricoid cartilage, supratracheal partial laryngectomies expanded the indications to some LCSs not involving the entire cricoid lamina sparing laryngeal function and avoiding the need for total laryngectomy.
