Corticosteroids suppress in vitro tonsillar proliferation in children with obstructive sleep apnoea
European Respiratory Journal, 2009
Intranasal corticosteroids (CS) are potentially useful interventions for children with obstructive sleep apnoea (OSA), and may reduce lymphadenoid tissue size in the upper airway. The present authors hypothesised that CS would reduce cellular proliferation and the production of pro-inflammatory cytokines in a tonsil/adenoid mixed-cell culture system. Dissociated tonsils or adenoids harvested intra-operatively from children with polysomnographically diagnosed OSA were cultured in control medium (CO) or after stimulation with lipopolysaccharide and concanavalin A (STIM), and incubated with dexamethasone (DEX; 10 -5 -10 -7 M), fluticasone (FLU; 10 -5 -10 -14 M) and budesonide (BUD; 10 -4 -10 -14 M). Proliferation and apoptosis were assessed, and supernatants were assayed for the cytokines tumour necrosis factor (TNF)-a, interleukin (IL)-6 and IL-8.

Background and Objective Many studies have supported the potential effect of anti-inflammatory medications treatment for childhood obstructive sleep apnea (OSA). This study aimed to evaluate the outcomes of intranasal corticosteroid treatment in children with OSA symptoms and adenoid hypertrophy (AH), and to identify factors associated with the treatment outcome.Methods This retrospective study included children aged 1–15 years who snored, had sleeprelated symptoms, and received intranasal corticosteroid treatment for 4–16 weeks. Treatment outcome was considered a success if all symptoms were completely resolved or if the child still snored without sleep-related symptoms; treatment was considered a failure if the child still snored and had concomitant sleep-related symptoms.Results Among the 328 eligible children, 109 (33.2%) experienced treatment failure. The age of the children was significantly higher in the failure group than in the success group (median [interquartile range], 5...

Introduction and objectives: Adenoid hypertrophy and sleep disordered breathing (SDB) are generally considered common diseases of childhood. Oral corticosteroids have been used to treat upper airway blockages through their anti-inflammatory and lympholytic impacts. Although nasal corticosteroids are widely used in adenoid hypertrophy, there are few information about the effects of oral corticosteroids to the adenoid tissue. We supposed that oral corticosteroid treatment may be helpful in adenoid hypertrophy due to its inflammatory related background. According to this idea we evaluated the effect of short-term oral corticosteroid treatment on adenoid hypertrophy in patients receiving oral corticosteroids for any other reasons. Methods: A prospective, observational study was conducted. In total, 51 children (2–11years old) were enrolled into this study. All patients received a 3-day course of oral corticosteroid (1 mg/kg) treatment. They were evaluated before treatment and immediatel...
Inflammatory Factors: Nonobese Pediatric Obstructive Sleep Apnea and Adenotonsillectomy
Journal of Clinical Medicine, 2020
Background: Inflammation is often considered relating to pediatric obstructive sleep apnea (OSA). We conducted a study investigating cytokines, including Il-17 and Il-23, in children with OSA before and after adenotonsillectomy (T&A), compared with controls. Methods: Children with OSA between age 4 and 12 receiving T&A were prospectively followed. Evaluation before and reevaluation six months after the treatment were done, including polysomnography (PSG), blood tests, and questionnaires. Blood samples were obtained to determine the values of high-sensitivity-C-reactive-protein (HS-CRP); tumor-necrosis-factor-alpha (TNF-α); and interleukin (IL)-1, 6, 10, 12, 17, and 23. We compared the results with an age-matched control group. Results: We included 55 OSA children and 32 controls. Children with OSA presented significant improvement after T&A in complaints, signs, apnea hypopnea index (AHI) (p < 0.001), mean oxygen desaturation index (p < 0.001), and mean oxygen saturation (p = 0.010). Upon entering this study, children with OSA had significantly higher cytokine levels than the controls and significant changes in HS-CRP (p = 0.013), TNF-α (p = 0.057), IL-1β (p = 0.022), IL-10 (p = 0.035), and IL-17 (p = 0.010) after T&A. Children with improved but persistently abnormal AHI did not have all cytokine levels normalized, particularly IL-23 and HS-CRP. Conclusion: Sleep-disordered breathing can persist after T&A and can continue to have a negative inflammatory effect. HS-CRP and IL-23 may serve as blood markers for the persistence of sleep-disordered breathing after T&A.

To determine if pediatric obstructive sleep apnea syndrome (OSAS) caused by adenotonsillar hypertrophy (ATH) could be treated by a short course of systemic corticosteroids, we conducted an openlabel pilot study in which standardized assessments of symptomatology, OSAS severity, and adenotonsillar size were performed before and after a 5-day course of oral prednisone, 1.1 0.1 (+ SE) mgkg per day. Outcome measures included symptom severity, adenotonsillar size, and polysomnographic measures of OSAS. Selection criteria included age from 1 to 12 years, ATH, symptomatology suggesting OSAS, an apneahypopnea index ( M I ) 2 3/hour, and intent to perform adenotonsillectomy. Only one of nine children showed enough improvement to avoid adenotonsillectomy. Symptomatology did not improve after corticosteroid treatment but did after removal of tonsils and adenoids. Polysomnographic indices of OSAS severity did not improve after corticosteroid treatment. After corticosteroids, tonsillar size decreased in only two patients, adenoidal size was only marginally reduced, and the size of the nasopharyngeal airway was not significantly increased. These results sug gest that a short course of prednisone is ineffective in treating pediatric OSAS caused by ATH.

Purpose Local and systemic inflammatory markers and pro-inflammatory cytokines are increased in children with obstructive sleep apnea syndrome (OSAS). Therefore, systemic or topical anti-inflammatory agents are used to treat this syndrome. We evaluated the treatment with systemic corticosteroids in children with severe OSAS and adenotonsillar hypertrophy before surgery. Methods This was an unblinded open label study. Children with severe OSAS (diagnosed through polysomnography, obstructive apnea-hypopnea index [AHI] > 10 eV/h) were recruited. Exclusion criteria included age < 3 years, history of acute or chronic cardiorespiratory or neuromuscular or metabolic disease; major craniofacial abnormalities; and chromosomal syndromes and epilepsy. Computer-generated random numbers were used for simple randomization of subjects. All children were treated with intranasal beclomethasone spray, and 15 children additionally received oral betamethasone and 0.1 mg/ kg per day for 7 days. Sleep clinical record (SCR) and pulsoximetry were performed before and after 7 days in all children. Results Among 28 children with severe OSAS mean age was 4.5 ± 1.8 years, AHI 20.4 ± 1.8 eV/h). In children treated with intranasal and oral corticosteroids, mean (95.3 ± 1.1 vs 97.0 ± 0.8%, p = 0.0001) and minimum oxygen saturation (78.8 ± 6.3 vs 89.2 ± 4.2, p = 0.001) improved, and the SCR score (12.6 ± 1.2 vs 8.3 ± 1.1, p = 0.0001) was reduced. Children treated only with intranasal beclomethasone spray showed no differences in outcome measures before and after treatments. When we considered the oximetry measures, after corticosteroid treatment, we obtained statistical differences between the 2 groups (p < 0.01). Conclusions These results seem to suggest that a short course of oral betamethasone could be useful to treat children with severe OSAS and adenotonsillar hypertrophy waiting for surgery.
Anti-inflammatory therapy for obstructive sleep apnea in children
PubMed, 2011
Question: A 4-year-old child was diagnosed by polysomnography as experiencing mild obstructive sleep apnea (OSA). Despite the child being inattentive and distracted during the day at school, his parents prefer to avoid surgical treatment (adenotonsillectomy). Are there any non-surgical treatments for mild OSA in young children? Answer: Obstructive sleep apnea in children is caused mainly by adenotonsillar hypertrophy and can lead to considerable morbidities, including neurocognitive and behavioural disturbances. Surgical removal of the tonsils and adenoids is the treatment of choice. In recent years, however, a new understanding of the inflammatory components of OSA has led to the assumption that anti-inflammatory treatment can reduce adenotonsillar size and improve OSA symptoms. Evidence from a few studies suggests that intranasal steroids and oral leukotriene receptor antagonists have beneficial effects, but data from randomized controlled trials are still lacking.

Tonsillectomy and adenoidectomy (T&A) is a frequent surgical procedure in children with obstructive sleep apnea (OSA). Many symptomatic children who do not fulfill the currently recommended criteria for T&A may benefit from topical intranasal steroid therapy. However, the expression of glucocorticoid receptor (GCR) expression in adenoid and tonsillar tissue is currently unknown. The objective of this study was to assess and compare expression patterns of the human GCR in children who undergo T&A for either recurrent throat infections (RI) or OSA. Adenotonsillar tissues from 36 children with OSA or RI were subjected to quantitative PCR using specific primers for GCR-alpha and GCR-beta and to immunohistochemistry and Western blotting for protein expression of GCR isoforms. mRNA encoding for expression of both GCR-alpha and GCR-beta was detected in the tonsils and adenoids of all children, with markedly higher relative abundance of the GCR-alpha. Furthermore, GCR-alpha mRNA expression ...

The study aims to explore the inflammatory cytokines and oxidative stress in children with obstructive sleep apnea syndrome (OSAS) triggered by adenoids and/or tonsillar hypertrophy and their changes after adenotonsillectomy (AT) and to investigate the associated behavioral disorders in OSAS, before and after AT. Thirty patients with OSAS and 20 healthy children, aged 3 - 13 years were included in the study. According to apnea-hypopnea index (AHI), OSAS children were classified into 3 groups: mild (n = 19), moderate (n = 5), and severe OSAS (n = 6). Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), interleukin (IL)-6, tumor necrosis factor (TNF)-α, malondialdehyde (MDA) and antioxidant enzymes activities were assessed in serum, preoperative and 6 weeks after AT. TNF-α, IL-6 and malondialdehyde levels were also estimated in adenoid and tonsils tissues. A Pediatric Sleep Questionnaire was completed by the parents before and after AT. As a result of the study, we obtained...
