Intranasal flunisolide treatment in children with adenoidal hypertrophy

Serum CXCL-1 as a predictive biomarker for glucocorticoid resistance in adenoids of patients with adenoid hypertrophy

PURPOSE

The objective of this study was to elucidate the relationship between adenoid hypertrophy (AH) and glucocorticoid resistance, and to investigate the potential reasons for the suboptimal therapeutic response to intranasal glucocorticoids (INS) in pediatric patients with AH.

METHODS

The present study enrolled a cohort of 110 patients diagnosed with AH, all of whom underwent adenoidectomy at Renmin Hospital of Wuhan University between June 2023 and September 2023. Immunohistochemistry and real-time quantitative polymerase chain reaction (RT-qPCR) were employed to assess the levels of inflammatory cytokines, and glucocorticoid receptors (GR, including GRα and GRβ) in adenoidal tissues. The Pearson correlation analysis was employed to ascertain the relationship between the levels of GR and inflammatory cytokines. The receiver operating characteristic (ROC) curve to evaluate the predictive efficacy of inflammatory cytokines in serum in assessing the glucocorticoid sensitivity and the expression of GR.

RESULTS

Compared with the AH not associated with allergic rhinitis (AH-nAR) group, patients with AH-AR exhibit heightened eosinophilic inflammation and comorbid symptoms of AR. In patients with AH-nAR and those with poor glucocorticoid response, adenoidal tissues showed lower GRα expression and higher GRβ expression. Furthermore, IL-1β, CXCL-1, and CXCL-2 were simultaneously associated with a negative correlation with GRα, and a positive correlation with GRβ. Compared with IL-1β and CXCL-2, CXCL-1 in serum demonstrated a more significant predictive accuracy in discerning glucocorticoid sensitivity and evaluating the expression of GRα and GRβ.

CONCLUSION

In patients with AH-nAR and those with poor glucocorticoid response, evidence of glucocorticoid resistance is observed within adenoidal tissues. Serum CXCL-1 may serve as a potential predictive biomarker for glucocorticoid resistance in AH patients, suggesting that surgical intervention should be more heavily considered for this cohort of patients.

Inter-societal Delphi Consensus on the topical nasal treatments in Italy

Topical nasal therapy is widely used in clinical practice by different specialists. However, it is multifaceted and still controversial. Namely, there is no consensus about the many aspects, and there needs to be specific guidelines. Four independent experts involved 14 Italian scientific societies (concerning ENT, allergy, and pediatrics areas) to participate in generating an Intersocietal Delphi Consensus on this matter. Three iterative rounds collected experts (4 in the first round, 20 in the second round, and 45 in the third round) designed by the scientific societies based on their clinical expertise and documented scientific value. Thirty-four statements were discussed and voted on. At the second round, all statements accomplished a very high consensus grade (>95%). At the third round, many statements reached a high or very high grade of consensus (>70%). However, some statements did not obtain sufficient agreement. Consequently, there is a need to implement knowledge about this issue through educational initiatives and new studies conducted with a robust methodology. In conclusion, topical nasal therapy deserves adequate knowledge as it is widespread and fruitful in managing upper respiratory diseases.

Maximal medical treatment of adenoid hypertrophy: a prospective study of preschool children

PURPOSE

This study aimed to examine the effectiveness of the combined maximal medical treatment for adenoid hypertrophy in preschool children.

METHODS

Sixty-four children underwent one-year combined therapy with intranasal mometasone furoate, oral desloratadine, nasal saline irrigation, and bacteriotherapy. Additionally, decongestion drops were applied during scheduled breaks.

RESULTS

Of the 64 treated children, 72% showed clinical improvement in adenoid symptoms while 28% did not improve and underwent surgery. These groups differed significantly in terms of the overall reduction in ailments after treatment (p < 0.001), infection rate (p < 0.001), catarrh severity (p < 0.001) and nasal patency (p < 0.001). Endoscopic examination confirmed that responders experienced, on average, a decrease of 8.4% in the adenoid/choana ratio and an improvement in mucosal coverage of the adenoid. These effects were not observed in the group of children whose parents opted for surgery after nine months of conservative treatment.

CONCLUSIONS

The proposed new schema of long-term maximal medical treatment with the use of combined intermittent treatment of intranasal mometasone furoate and decongestion drops, oral desloratadine, nasal saline irrigation, and bacteriotherapy can be attempted in patients with adenoid hypertrophy symptoms, and responders may avoid the need for surgery. The applied treatment breaks resulted in a low number of therapeutic side effects.

The First-Line Approach in Children with Obstructive Sleep Apnea Syndrome (OSA)

Obstructive sleep apnea syndrome (OSA) is the main manifestation of sleep-disordered breathing in children. Untreated OSA can lead to a variety of complications and adverse consequences mainly due to intermittent hypoxemia. The pathogenesis of OSA is multifactorial. In children aged 2 years or older, adenoid and/or tonsil hypertrophy are the most common causes of upper airway lumen reduction; obesity becomes a major risk factor in older children and adolescents since the presence of fat in the pharyngeal soft tissue reduces the caliber of the lumen. Treatment includes surgical and non-surgical options. This narrative review summarizes the evidence available on the first-line approach in children with OSA, including clinical indications for medical therapy, its effectiveness, and possible adverse effects. Literature analysis showed that AT is the first-line treatment in most patients with adenotonsillar hypertrophy associated with OSA but medical therapy in children over 2 years old with mild OSA is a valid option. In mild OSA, a 1- to 6-month trial with intranasal steroids (INS) alone or in combination with montelukast with an appropriate follow-up can be considered. Further studies are needed to develop an algorithm that permits the selection of children with OSA who would benefit from alternatives to surgery, to define the optimal bridge therapy before surgery, to evaluate the long-term effects of INS +/- montelukast, and to compare the impact of standardized approaches for weight loss.

150th Anniversary of global adenoid investigations: unanswered questions and unsolved problems

Although the problem of adenoid hypertrophy (AH) has been diagnosed and treated by doctors and scientists from around the world for the last 150 years, there is still no consensus regarding appropriate diagnosis, conservative treatment options, and qualification for surgery. This manuscript presents current knowledge on these issues and compares diagnostic methods and the effectiveness of treatment options. Factors that may influence the obtained treatment results are also described, and a questionnaire is proposed to compare the results of treatment. The objective of drawing attention to this problem is to obtain better results from conservative treatment in the future and better-qualified patients for surgical treatment.

Efficacy of Topical Azelastine and Fluticasone Dipropionate Combination in Children With Adenoid Hypertrophy

OBJECTIVE

Adenoid hypertrophy (AH) is one of the common childhood diseases. Surgical and non-surgical treatment of AH in children is planned according to the severity of symptoms and associated complications. In recent years, treatment methods with intranasal sprays have been reported quite frequently in uncomplicated cases. We aim to evaluate the effectiveness of a new combination of azelastine - fluticasone (AZE-FLU) (137mcg azelastine and 50mcg fluticasone) nasal spray in children with uncomplicated AH.

METHODS

Sixty-five children diagnosed with AH were included in the study. The mean age of the children was 7.42 ± 2.26 (4-13 years). The cohort consisted of 29 males and 36 females. All children were evaluated clinically and endoscopically. AZE-FLU nasal spray was applied to both nostrils twice a day for three months. Adenoid/choana ratio and symptom scores were evaluated before treatment and at the end of the 12th week.

RESULTS

At the end of 24 weeks of AZE-FLU application, there was a statistically significant decrease in both adenoid/choana ratio and symptom scores. While the initial adenoid/choana (A/C) score was 3.57 ± 0.58, it decreased to 1.74 ± 0.61 following treatment. A dramatic decrease in total symptom scores was observed. The total symptom score average was 15.63 ± 1.28 before treatment, while it was 2.31 ± 1.4 after the treatment with the difference being statistically significant (P < .01).

CONCLUSION

In this study, the effectiveness of AZE-FLU nasal spray on AH was investigated for the first time. This treatment provides an effective alternative to the surgical approach in children with uncomplicated adenoid hypertrophy. Using this protocol, 96% of patients were removed from the surgery list.

The Long-Term Effects of 12-Week Intranasal Steroid Therapy on Adenoid Size, Its Mucus Coverage and Otitis Media with Effusion: A Cohort Study in Preschool Children

BACKGROUND

The purpose of this study is to analyse the long-term effects of a 12-week course of topical steroids on adenoid size and its mucus using endoscopy and on middle ear effusion measured by tympanometry.

METHODS

The study presents an endoscopic choanal assessment of the change in adenoid size (adenoid to choanae ratio, A/C ratio) and its mucus coverage in 165 children with Grade II and III adenoid hypertrophy three to six months after finishing a 12-week course of intranasal steroid treatment with mometasone furoate. Additionally, tympanometry was performed to measure middle ear effusion. Changes in the tympanograms were analysed.

RESULTS

The mean A/C ratio before treatment was 65.73%. Three to six months after finishing a 12-week course of intranasal steroid treatment, the mean A/C ratio decreased to 65.52%, although the change was not statistically significant (p = 0.743). There was no change in adenoid mucus according to the MASNA scale before and three to six months after the end of the steroid treatment (p = 0.894). Long-term observations of tympanograms before and three to six months after the end of the treatment did not show improvement (p = 0.428).

CONCLUSIONS

The results indicate that there was no effect of topical steroids on adenoid size, its mucus and otitis media with effusion (OME) three to six months after finishing a 12-week course of treatment. In the light of performed study, decision of adenoidectomy and tympanostomy should not be procrastinated.

Safety and Efficacy of Maxitrol in Pediatric Age Group Below Two Years With Adenoid Hypertrophy: A Retrospective Cohort Study

Introduction Adenoid hypertrophy, a common condition in children, represents one of the common indications for surgery in pediatrics. Medical treatment alone is not effective, and most of the time patients are managed by surgical removal of the adenoid. The aim of this study is to assess the safety and efficacy of intranasal Maxitrol® drops (Novartis Pharmaceuticals, Basel, Switzerland) in pediatric patients with adenoid hypertrophy aged less than two years and to document any side effects during its use. Methods This retrospective cohort study was conducted at King Abdullah Specialist Children's Hospital (KASCH). We reviewed the charts of 86 pediatric patients aged less than two years who were diagnosed with adenoid hypertrophy between 2015 and 2018. Patients were grouped according to the type of intervention (use of Maxitrol®, and no use). The follow-up time was up to one year. Results Out of 86 patients, 55 (63.9%) patients had adenoid hypertrophy alone and 31 (36.1%) had adenoid hypertrophy plus another disease. Patients with obstructive sleep apnea symptoms (p=0.026) and grade of adenoid (p=0.040) showed a significant relationship with surgery booking after one year. The probability of booking for surgery for those who used Maxitrol® was 1.394 times higher than for those who were not using it (odds ratio [OR]=1.394; 95% confidence interval [CI]=0.549-3.537). Suppression of growth and eye complications were not reported in any of our patients. Conclusion In this small sample, the use of Maxitrol® in the pediatric age group below two years with adenoid hypertrophy was safe and effective in relieving nasal symptoms; however, eventually, surgery was needed in most of our patients. Suppression of growth and eye complications were not reported in any of our patients during the follow-up time.

Inflammation, infection, and allergy of upper airways: new insights from national and real-world studies

The upper airways (UA) should be considered as a functional unit. Current functional anatomy divides URT in three, mutually dependent, "junction boxes": i) the ostio-meatal complex (OMC), ii) the spheno-ethmoidal recess (SER), and iii) the rhinopharynx (RP). Correct ventilation and effective mucociliary clearance of these sites significantly affect the healthy physiology of the entire respiratory system. The OMC, SER, and RP obstruction is the first pathogenic step in the inflammatory/infectious cascade of UA disorders. The inflammation of the respiratory mucosa is the main pathogenic factor for airway obstruction. Moreover, bacterial biofilm (a strategy modality of bacterial survival) is an important local cause of systemic antibiotic ineffectiveness, recurrent infections, and antibiotic resistance. Health microbiota guarantees UA wellness; on the contrary, dysbiosis promotes and worsens UA infections. Allergy, namely type 2 inflammation, is a common cause of UA obstruction such as promoting in turn infections. Fiberoptic endoscopy is a mandatory diagnostic tool in clinical practice. Nasal cytology, mainly concerning flow cytometry, allows defining rhinitis phenotypes so allowing a precision medicine approach. Several conventional therapeutic approaches are available, but efficacy and safety should be ever properly considered before the prescription. Also, complementary medicine plays a fruitful role in the management of UA diseases. National and real-world studies are reported and discussed as they may be useful in daily clinical practice.

Anti-inflammatory medications for obstructive sleep apnoea in children

BACKGROUND

Obstructive sleep apnoea (OSA) is characterised by partial or complete upper airway obstruction during sleep. Approximately 1% to 4% of children are affected by OSA, with adenotonsillar hypertrophy being the most common underlying risk factor. Surgical removal of enlarged adenoids or tonsils is the currently recommended first-line treatment for OSA due to adenotonsillar hypertrophy. Given the perioperative risk and an estimated recurrence rate of up to 20% following surgery, there has recently been an increased interest in less invasive alternatives to adenotonsillectomy. As the enlarged adenoids and tonsils consist of hypertrophied lymphoid tissue, anti-inflammatory drugs have been proposed as a potential non-surgical treatment option in children with OSA.

OBJECTIVES

To assess the efficacy and safety of anti-inflammatory drugs for the treatment of OSA in children.

SEARCH METHODS

We identified trials from searches of the Cochrane Airways Group Specialised Register, CENTRAL and MEDLINE (1950 to 2019). For identification of ongoing clinical trials, we searched ClinicalTrials.gov and the World Health Organization (WHO) trials portal.

SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing anti-inflammatory drugs against placebo in children between one and 16 years with objectively diagnosed OSA (apnoea/hypopnoea index (AHI) ≥ 1 per hour).

DATA COLLECTION AND ANALYSIS

Two authors independently performed screening, data extraction, and quality assessment. We separately pooled results for the comparisons 'intranasal steroids' and 'montelukast' against placebo using random-effects models. The primary outcomes for this review were AHI and serious adverse events. Secondary outcomes included the respiratory disturbance index, desaturation index, respiratory arousal index, nadir arterial oxygen saturation, mean arterial oxygen saturation, avoidance of surgical treatment for OSA, clinical symptom score, tonsillar size, and adverse events.

MAIN RESULTS

We included five trials with a total of 240 children aged one to 18 years with mild to moderate OSA (AHI 1 to 30 per hour). All trials were performed in specialised sleep medicine clinics at tertiary care centres. Follow-up time ranged from six weeks to four months. Three RCTs (n = 137) compared intranasal steroids against placebo; two RCTs compared oral montelukast against placebo (n = 103). We excluded one trial from the meta-analysis since the patients were not analysed as randomised. We also had concerns about selective reporting in another trial. We are uncertain about the difference in AHI (MD -3.18, 95% CI -8.70 to 2.35) between children receiving intranasal corticosteroids compared to placebo (2 studies, 75 participants; low-certainty evidence). In contrast, children receiving oral montelukast had a lower AHI (MD -3.41, 95% CI -5.36 to -1.45) compared to those in the placebo group (2 studies, 103 participants; moderate-certainty evidence). We are uncertain whether the secondary outcomes are different between children receiving intranasal corticosteroids compared to placebo: desaturation index (MD -2.12, 95% CI -4.27 to 0.04; 2 studies, 75 participants; moderate-certainty evidence), respiratory arousal index (MD -0.71, 95% CI -6.25 to 4.83; 2 studies, 75 participants; low-certainty evidence), and nadir oxygen saturation (MD 0.59%, 95% CI -1.09 to 2.27; 2 studies, 75 participants; moderate-certainty evidence). Children receiving oral montelukast had a lower respiratory arousal index (MD -2.89, 95% CI -4.68 to -1.10; 2 studies, 103 participants; moderate-certainty evidence) and nadir of oxygen saturation (MD 4.07, 95% CI 2.27 to 5.88; 2 studies, 103 participants; high-certainty evidence) compared to those in the placebo group. We are uncertain, however, about the difference in desaturation index (MD -2.50, 95% CI -5.53 to 0.54; 2 studies, 103 participants; low-certainty evidence) between the montelukast and placebo group. Adverse events were assessed and reported in all trials and were rare, of minor nature (e.g. nasal bleeding), and evenly distributed between study groups. No study examined the avoidance of surgical treatment for OSA as an outcome.

AUTHORS' CONCLUSIONS

There is insufficient evidence for the efficacy of intranasal corticosteroids for the treatment of OSA in children; they may have short-term beneficial effects on the desaturation index and oxygen saturation in children with mild to moderate OSA but the certainty of the benefit on the primary outcome AHI, as well as the respiratory arousal index, was low due to imprecision of the estimates and heterogeneity between studies. Montelukast has short-term beneficial treatment effects for OSA in otherwise healthy, non-obese, surgically untreated children (moderate certainty for primary outcome and moderate and high certainty, respectively, for two secondary outcomes) by significantly reducing the number of apnoeas, hypopnoeas, and respiratory arousals during sleep. In addition, montelukast was well tolerated in the children studied. The clinical relevance of the observed treatment effects remains unclear, however, because minimal clinically important differences are not yet established for polysomnography-based outcomes in children. Long-term efficacy and safety data on the use of anti-inflammatory medications for the treatment of OSA in childhood are still not available. In addition, patient-centred outcomes like concentration ability, vigilance, or school performance have not been investigated yet. There are currently no RCTs on the use of other kinds of anti-inflammatory medications for the treatment of OSA in children. Future RCTs should investigate sustainability of treatment effects, avoidance of surgical treatment for OSA, and long-term safety of anti-inflammatory medications for the treatment of OSA in children and include patient-centred outcomes.

Adenoidal Immune Response in the Context of Inflammation and Allergy

:

The mucosal-associated lymphoid tissues of the upper respiratory tract, including adenoids and palatine tonsils, are considered as the first line of defense against respiratory infections, being important effector organs in both mucosal-type and systemic-type adaptive immunity. They are strategically located for mediating both local and regional immune functions, as they are exposed to antigens from both the inhaled air (allergens and pathogens) and the alimentary tract. Adenoids play a major role in the early and effective immune responses against viral and bacterial upper airway infections, as well as in the development of allergic reactions to respiratory allergens, being influenced by several environmental antigens and pollutants, such as tobacco smoke. In addition, recent studies have focused on new immune-modulating strategies for adenoidal cells as a preventive and therapeutic approach for chronic upper airways inflammation.

:

Herein, we aimed to summarize what is known about the cellular and molecular mechanisms regulating adenoidal immune responses in the context of inflammation and allergy, with particular reference to scientific literature published within the last five years.

Mometasone furoate intranasal spray is effective in reducing symptoms and adenoid size in children and adolescents with adenoid hypertrophy

INTRODUCTION

The use of mometasone furoate (MF) intranasal spray in treating adenoid hypertrophy (AH) has a variable outcome due the different methods of adenoid size evaluation. The aim of our study was to evaluate the effect of MF intranasal spray in children and adolescents with AH using a reliable and consistent endoscopic evaluation.

MATERIAL AND METHOD

A prospective interventional study was conducted. Evaluation took place during the first visit (week 0) and second visit (week 12). Symptoms of nasal obstruction, rhinorrhoea, cough and snoring were assessed, and an overall total symptoms score was obtained. A rigid nasoendoscopic examination using a four-grading system of adenoid size from 1 to 4 was performed. Patients were treated with MF intranasal spray for 12 weeks. Patients' aged 7-11-years old used 1 spray in each nostril once daily, while patients aged 12-17 used two sprays in each nostril once daily. Reassessment was carried out during the second visit (week 12).

RESULTS

A total of 74 patients was recruited. There were significant improvements from week 0 to week 12 in the symptoms' score for nose obstruction, rhinorrhoea, cough, snoring including the total nasal symptoms' score (p<0.001). AH significantly reduced in size from week 0 (2.89±.87) to week 12 (1.88±.83) (p<0.001).

CONCLUSION

MF intranasal spray is effective in improving the symptoms attributed to AH as well as reducing the adenoid size. MF intranasal spray is advocated as a treatment option before adenoidectomy is considered.

Use of intranasal corticosteroids in adenotonsillar hypertrophy

Objectives:

This review examined the efficacy of intranasal corticosteroids for improving adenotonsillar hypertrophy.

Method:

The related literature was searched using PubMed and Proquest Central databases.

Results:

Adenotonsillar hypertrophy causes mouth breathing, nasal congestion, hyponasal speech, snoring, obstructive sleep apnoea, chronic sinusitis and recurrent otitis media. Adenoidal hypertrophy results in the obstruction of nasal passages and Eustachian tubes, and blocks the clearance of nasal mucus. Adenotonsillar hypertrophy and obstructive sleep apnoea are associated with increased expression of various mediators of inflammatory responses in the tonsils, and respond to anti-inflammatory agents such as corticosteroids. Topical nasal steroids most likely affect the anatomical component by decreasing inspiratory upper airway resistance at the nasal, adenoidal or tonsillar levels. Corticosteroids, by their lympholytic or anti-inflammatory effects, might reduce adenotonsillar hypertrophy. Intranasal corticosteroids reduce cellular proliferation and the production of pro-inflammatory cytokines in a tonsil and adenoid mixed-cell culture system.

Conclusion:

Intranasal corticosteroids have been used in adenoidal hypertrophy and adenotonsillar hypertrophy patients, decreasing rates of surgery for adenotonsillar hypertrophy.

Is the effect of topical intranasal steroids on obstructive adenoids transient or long-lasting? Case series and systematic review of literature

Objectives:

To study and review the short- and long-term effects of intranasal steroids on obstructive adenoids.

Methods:

In this prospective cohort study, 19 children previously treated with mometasone furoate for 3 months were contacted at 3, 6 and 12 months after cessation of treatment. Main outcome measures included: change in severity of nasal obstruction, allergic rhinitis and obstructive symptoms. A systematic review of literature was also performed.

Results:

By one year, 25 per cent of patients required adenoidectomy; the remaining children had no significant change in clinical score (p = 0.464), obstruction severity (p = 0.191) or allergic symptoms (p = 0.284). Fourteen pertinent studies were identified; all but one study showed improvement in the patients’ symptoms and/or degree of obstruction. Two studies with follow up reaching 25 months showed positive effects.

Conclusion:

The short-term positive effect of some intranasal steroids on obstructive adenoids seems to persist in a significant number of patients after the cessation of treatment.

Role of mometasone furoate aqueous nasal spray for management of adenoidal hypertrophy in children

Objectives:

To study the role of mometasone furoate aqueous nasal spray for the management of adenoidal hypertrophy in children with more than 50 per cent obstruction, and to assess its impact on change in quality of life.

Methods:

A prospective, randomised, double-blind, interventional placebo-controlled study was conducted. A total of 100 children aged 2–12 years completed treatment and follow up. The symptoms and degree of obstruction were evaluated by nasopharyngoscopy conducted pre-treatment and 24 weeks post-treatment. Subjects received mometasone furoate nasal spray at a daily dose of 200 µg for 8 weeks, followed by a dose of 200 µg on alternate days for 16 weeks. Results were compared with those of a matched control group who were given saline nasal spray.

Results:

With mometasone treatment, there was an 89.8 per cent reduction in clinical symptom score, and the degree of obstruction dropped from 87 to 72 per cent (p < 0.0001). A statistically significant change in quality of life scores was seen in patients treated with the mometasone nasal spray (score change of 37.47) as compared with those given saline nasal spray (score change of 11.25) (p = 0.0001).

Conclusion:

Mometasone nasal spray appears to be effective in treating children with obstructive adenoids.

[Medicinal treatment of breathing disorders in adenotonsillar hyperplasia]

BACKGROUND

Adenotonsillar hyperplasia (ATH) can lead to severe breathing disorders, such as impaired nasal breathing, mouth breathing, snoring and obstructive sleep apnea. In such cases ATH should be treated mostly by performing adenoidectomy and/or adenotonsillectomy. There is increasing evidence that anti-inflammatory medication (AIM) is effective in treating ATH-related breathing disorders.

OBJECTIVES

The aim of this study was to provide evidence and recommendations for the use of AIM in the treatment of ATH-related breathing disorders.

METHODS

In this study 12 national pediatric sleep experts were included into a Delphi process and formulated indications and recommendations.

RESULTS

The use of AIM in the treatment of ATH-related breathing disorders is sufficiently supported by the results of randomized controlled trials and systematic reviews. Nasal beclometason and nasal mometason have been studied for the treatment of enlarged adenoids and nasal fluticason and oral montelukast for the treatment of obstructive sleep apnea. The use of AIM for first-line treatment should be restricted to selected indications, such as a characteristic patient age and exclusion of an acute upper respiratory tract infection. Evidence-based recommendations are given concerning indications, dosage, treatment duration and correct administration of AIM.

CONCLUSIONS

Anti-inflammatory medications are simple and effective alternatives for the treatment of ATH-related breathing disorders. These guidelines are intended to promote the use of AIM by pediatricians in ambulatory care settings.

Effect of intratonsillar injection of steroids on the palatine tonsils of rabbits

OBJECTIVES/HYPOTHESIS

Nasal steroids may significantly improve nasal obstructive symptoms with a reduction of adenoid size in children, but they do not consistently yield the same concurrent effect on enlarged palatine tonsils. Failure of nasal steroids to decrease the size of palatine tonsils is believed to be attributable to location and washout by saliva. The purpose of this study was to determine if direct application of steroid via intratonsillar injection would reduce the size of palatine tonsils in the rabbit model.

STUDY DESIGN

Prospective animal study.

METHODS

Eight rabbits (16 tonsils) were administered intratonsillar injections of fluticasone (n = 8, 1 mg/ml) or saline (n = 8, 0.1 ml) on days 0, 3, 7, 10, 14, and 17. Two rabbits (4 tonsils) received a single steroid injection to compare single versus multiple steroid injections. The rabbit's tonsil size was measured before each injection. After the fifty injections, the tonsils were harvested for histologic analysis.

RESULTS

A total of 16 tonsils were analyzed. After five steroid injections, the reduction (-7.7 mm(2)  ± 4.27) in size was statistically significant when compared to reduction (6.12 mm(2)  ± 6.57) in the saline injected group (P = 0.001). Repeated steroid injection was more potent than a single injection (-3.00 mm(2)  ± 3.08) in reducing the size (P = 0.006). In histologic analysis, tonsils after repeated steroid injections were significantly smaller than saline-injected tonsils (P = 0.014), without obvious lymphoid follicles.

CONCLUSION

Repeated focal tonsillar injections of corticosteroids significantly reduced the size of palatine tonsils as compared to saline-injected controls. A single injection of corticosteroids appears to be effective, but not as effective, as multiple injections.

Role of intranasal steroid in the prevention of recurrent nasal symptoms after adenoidectomy

Background. Intranasal steroid provides an efficient nonsurgical alternative to adenoidectomy for theimprovement of adenoid nasal obstruction. Objective. To demonstrate the role of intranasal steroid in the prevention of adenoid regrowth after adenoidectomy. Methods. Prospective randomized controlled study. Two hundred children after adenoidectomy were divided into 2 groups. Group I received postoperative intranasal steroid and group II received postoperative intranasal saline spray. Both medications were administered for 12 weeks postoperatively. Patients were followed up for 1 year. Followup was done using the nasopharyngeal lateral X-rays, reporting the degree of the symptoms. Results. Significant difference between both groups after 6 months and after 1 year. The intranasal steroid group had significantly lower score after 6 months and after 1 year as regards nasal obstruction, nasal discharge, and snoring than the intranasal saline group. 2 weeks postoperatively, there was no difference between both groups as regards nasal obstruction, discharge, or snoring. As regards lateral radiographs, there was statistically significant difference between both groups 1 year but not 6 months postoperatively. Conclusion. Factors influencing the outcome of intranasal steroids therapy in the prevention of adenoid regrowth have not been identified. However, this treatment may obtain successful results in children to avoid readenoidectomy.

Management of chronic rhinosinusitis

: Chronic rhinosinusitis (CRS) in children is difficult to treat, with resultant frequent recurrences and failures. There are controversies in the treatment, mirroring the debate over the exact etiology of this disorder. The available medical treatments are antibiotics, topical nasal corticosteroids, and nasal lavage with saline solutions; though, there is no general agreement on the efficacy of the latter. The new technique of balloon sinuplasty allows ventilation to the sinuses to be restored with minimal risk and trauma to the tissues, and initial outcome seems promising, being successful in most treated children. Concerning the surgical approach, adenoidectomy is among the most frequent surgical procedures performed on children, but its therapeutic effect is controversial, because randomized studies have failed to prove that adenoidectomy alone is sufficient in curing CRS. Instead, functional endoscopic sinus surgery is a minimally invasive technique which restores the sinus ostia patency and can re-establish ventilation and drainage through the natural pathways. It is important that the effectiveness of any treatment is also evaluated by patient-reported outcomes (PROs) that refer to all health-related reports coming from the patients, without any involvement or interpretations by physician or others. Among PROs, health-related quality of life (HRQL) is the one most widely known and used. HRQL can be measured by means of validated questionnaires, which provide scores proportional to the degree of well-being perceived by patients. Concerning diseases of the upper airway including RS, there are numerous instruments specifically designed for children and caregivers, which allow to assess the effects of treatments in a more extensive and complete manner.

Anti-inflammatory medications for obstructive sleep apnea in children

BACKGROUND

Obstructive sleep apnea (OSA) is characterized by partial or complete upper airway obstruction during sleep. Approximately 1% to 4% of children are affected by OSA, with adenotonsillar hypertrophy the most common underlying risk factor. Surgical removal of enlarged tonsils and adenoids is the most commonly used treatment for OSA. Given the perioperative risk of the intervention and an estimated recurrence rate of up to 20%, there has recently been an increased interest in non-surgical treatment modalities. As the enlarged adenoids and tonsils consist of hypertrophied lymphoid tissue, anti-inflammatory agents have been proposed as a useful non-invasive treatment option in children with OSA.

OBJECTIVES

To assess the efficacy of anti-inflammatory drugs for the treatment of OSA in children.

SEARCH STRATEGY

We identified trials using searches of the Cochrane Airways Group Specialized Register, MEDLINE (1950 to 2010), EMBASE (1988 to 2010), CINAHL (1982 to 2010), CENTRAL (1964 to 2010), Web of Science (1900 to 2010), LILACS (1982 to 2010) and International Pharmaceutical Abstracts (IPA) (1970 to 2010).

SELECTION CRITERIA

Randomized controlled trials (RCTs) comparing anti-inflammatory drugs against placebo, other anti-inflammatory drugs, or other treatment in children between one and 16 years with objectively diagnosed OSA (Apnea Hypopnea Index (AHI) ≥ 1/hour (h)).

DATA COLLECTION AND ANALYSIS

Both authors independently performed data extraction and quality assessment. It was not possible to combine data from the included studies; we summarized data in a narrative fashion.

MAIN RESULTS

We included three RCTs. The first study was a six-week parallel-group trial (25 participants, mean age 3.8 years, mean AHI 10.8/h) of intranasal fluticasone versus placebo showed a statistically significant effect of the drug on improving the AHI. The second study compared intranasal budesonide with placebo in a six-week cross-over trial (62 participants, mean age 8.2 years, mean AHI 3.7/h). The authors reported an advantage of the drug over placebo in reducing the AHI. However, the patients were not analyzed as randomized so the result must be interpreted with caution. No valid group comparisons were reported for the third trial (30 participants, oral montelukast versus placebo in a 12-week parallel-group trial), which has so far only been published as an abstract.

AUTHORS' CONCLUSIONS

A single small study has found a short-term beneficial effect on the AHI in children with mild to moderate OSA. However, long-term safety and efficacy data are not available yet. Further RCTs are needed to evaluate anti-inflammatory drugs for OSA in children.

Non-surgical treatment of adenoidal hypertrophy: the role of treating IgE-mediated inflammation

Adenoidal hypertrophy (AH) and adenotonsillar hypertrophy are common disorders in the pediatric population and can cause symptoms such as mouth breathing, nasal congestion, hyponasal speech, snoring, and obstructive sleep apnea (OSA), as well as chronic sinusitis and recurrent otitis media. More serious long-term sequelae, typically secondary to OSA, include neurocognitive abnormalities (e.g. behavioral and learning difficulties, poor attention span, hyperactivity, below average intelligence quotient); cardiovascular morbidity (e.g. decreased right ventricular ejection fraction, left ventricular hypertrophy, elevated diastolic blood pressure); and growth failure. Adenoidectomy (with tonsillectomy in cases of adenotonsillar hypertrophy) is the typical management strategy for patients with AH. Potential complications have prompted the investigation of non-surgical alternatives. Evidence of a pathophysiologic link between AH and allergy suggests a possible role for intranasal corticosteroids (INS) in the management of patients with AH. This article reviews the epidemiology and pathophysiology of AH with a particular focus on evidence of its association with allergy and allergic rhinitis. Current treatment options are briefly considered with discussion on the rationale and evidence for the use of INS.

Medical treatment of adenoid hypertrophy with "fluticasone propionate nasal drops"

BACKGROUND

Adenoid hypertrophy treatment for children is generally planned in accordance with the degree of airway obstruction and related morbidity. If surgical treatment is indicated, the individual risk/benefit analysis of patients should be assessed in terms of anesthetic and postoperative complications. Although there are few alternative treatment options, these may be considered as a nonsurgical approach in less serious cases. Accordingly, studies about intranasal steroid applications under various protocols have been presented.

STUDY DESIGN

The prospective, randomized, placebo-controlled study.

SETTING

Tertiary referral center.

PATIENTS AND METHODS

Patients indicated for surgery were randomly divided into two groups. The study group was treated by fluticasone propionate nasal drops (NSD-nasal steroid drops) of 400 microg/day for 8 weeks. The control group was treated by normal saline (NS) in the same way. All the patients were called for follow-up every 4 weeks.

RESULTS

At the end of 8 weeks, statistically significant improvement (p<0.05) was observed in the NSD treated group compared to the NS treated group in terms of nasal airway obstruction, mouth breathing, speech abnormalities, apnea and night cough. At the end of 8 weeks, the average total symptoms score of the NSD treated group dropped from 13.7 to 2.9 while the NS treated group's score changed from 14.8 to 14.6. After 8 weeks of NSD treatment the initial adenoid/choana (A/C) rate had dropped from 87 to 56% and a total decrease of 35.6% was observed. After 8 weeks of NS treatment the A/C rate dropped from 87 to 85% and a total decrease of 2.2% was observed.

CONCLUSIONS

In this study, the effect of fluticasone propionate nasal drops on adenoid hypertrophy is examined for the first time. This method provides an effective alternative to surgical treatment in children with adenoid hypertrophy. With the protocol applied in this study 76% of the patients were eliminated the surgery and removed from the surgical waiting list.

Extracts fromThe Cochrane Library: Intranasal corticosteroids for moderate to severe adenoidal hypertrophy

The “Cochrane Corner” is a quarterly section in the Journal that highlights systematic reviews relevant to otolaryngology–head and neck surgery, with invited commentary to aid clinical decision making. This installment features a Cochrane Review entitled “Intranasal corticosteroids for nasal airway obstruction in children with moderate to severe adenoidal hypertrophy,” which finds limited evidence of a short-term improvement in nasal symptoms with a reduction of adenoid size.

Using nasal steroids to treat nasal obstruction caused by adenoid hypertrophy: does it work?

OBJECTIVE

To systematically review the evidence for the usage of nasal steroids to improve symptoms of nasal airway obstruction in children with adenoidal hypertrophy.

DATA SOURCES

Published studies indexed in the MEDLINE (1951 to 2008), EMBASE (1974 to 2008), and the Cochrane databases (Issue 3, 2008).

REVIEW METHODS

Data from the included trials were extracted and trial quality was assessed. Meta-analysis was not applicable and data were summarized in a narrative format. Evidence from excluded studies was also discussed.

RESULTS

Seven studies (six randomized controlled trials and one cohort study) met the inclusion criteria of the review, including a total of 493 patients. Six of these studies demonstrated significant efficacy of various nasal steroids (mometasone, beclomethasone, flunisolide) in improving nasal obstruction symptoms and in reducing adenoid size, as measured with symptom scores and fiber-optic nasopharyngeal endoscopy, respectively. The response appeared to be a group effect and may be maintained longer-term by continuing nasal steroids at a lower maintenance dose. The treatment was safe and well-tolerated with few minor adverse events.

CONCLUSION

The available evidence suggests that nasal steroids may significantly improve nasal obstruction symptoms in children with adenoid hypertrophy. This improvement appears to be associated with a reduction of adenoid size. Evidence of long-term efficacy is limited but suggests that in many children maintenance therapy is needed if symptom-relief is to persist. Further studies are required to support the use of nasal steroids as a first-line approach in these children.

Intranasal corticosteroids for nasal airway obstruction in children with moderate to severe adenoidal hypertrophy

BACKGROUND

Adenoidal hypertrophy is generally considered a common condition of childhood. When obstructive sleep apnoea or cardio-respiratory syndrome occurs, adenoidectomy is generally indicated. In less severe cases, non-surgical interventions may be considered, however few medical alternatives are currently available. Intranasal steroids may be used to reduce nasal airway obstruction.

OBJECTIVES

To assess the effectiveness of intranasal corticosteroids for improving nasal airway obstruction in children with moderate to severe adenoidal hypertrophy.

SEARCH STRATEGY

Our search included the Cochrane Ear, Nose and Throat Disorders Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 2, 2007), MEDLINE (1951 to 2007) and EMBASE (1974 to 2007). All searches were initially performed in May 2007 and updated in April 2008.

SELECTION CRITERIA

Randomised controlled trials comparing intranasal corticosteroids with placebo or no intervention or other treatment in children aged 0-12 years with moderate to severe adenoidal hypertrophy.

DATA COLLECTION AND ANALYSIS

Data from the included trials were extracted and trial quality was assessed by two authors independently. Meta-analysis was not applicable and data were summarised in a narrative format.

MAIN RESULTS

Five randomised trials, including a total of 349 patients, met the inclusion criteria of the review. All trials except one showed significant efficacy of intranasal corticosteroids in improving nasal obstruction symptoms and in reducing adenoid size. The first eight-week cross-over study showed that treatment with beclomethasone (336 micrograms/day) yielded a greater improvement in mean symptom scores than placebo (-18.5 vs. -8.5, P < 0.05) and a larger reduction in mean adenoid/choana ratio than placebo (right, -14% vs. +0.4%, p=0.002; left, -15% vs. -2.0%, p=0.0006) between week 0 and week 4. The second four-week cross-over study demonstrated that the nasal obstruction index decreased by at least 50% from baseline in 38% of patients treated with beclomethasone (400 micrograms/day) between week 0 and week 2, whereas none of the patients treated with placebo had such improvement (p<0.01). The third randomized, parallel-group trial showed that 77.7% of patients treated with mometasone (100 micrograms/day) for 40 days demonstrated an improvement in nasal obstruction symptoms and a decrease in adenoid size, such that adenoidectomy could be avoided, whereas no significant improvement was observed in the placebo group. The fourth randomized, parallel-group trial showed that eight-weeks of treatment with flunisolide (500 micrograms/day) was associated with a lager reduction in adenoid size than isotonic saline solution (p<0.05). In contrast, one randomised, parallel-group trial did not find significant improvement in nasal obstruction symptoms and adenoid size after eight weeks of treatment with beclomethasone (200 micrograms/day).

AUTHORS' CONCLUSIONS

Limited evidence suggests that intranasal corticosteroids may significantly improve nasal obstruction symptoms in children with moderate to severe adenoidal hypertrophy, and this improvement may be associated with a reduction of adenoid size. The long-term effect of intranasal corticosteroids in these patients remains to be defined.
