Abstract
BACKGROUND Despite the introduction of vaccination, there remains a need for pre-exposure prophylactic agents against SARS-CoV-2. Several patient groups are more vulnerable to SARS-CoV-2 infection by virtue of underlying health conditions, treatments received or suboptimal responses to vaccination. METHODS PROTECT-V is a platform trial testing pre-exposure prophylactic interventions against SARS-CoV-2 infection in vulnerable patient populations (organ transplant recipients; individuals with oncological/haematological diagnoses, immune deficiency or autoimmune diseases requiring immunosuppression or on dialysis). Multiple agents can be evaluated across multiple vulnerable populations sharing placebo groups, with the option of adding additional treatments at later time points as these become available. The primary endpoint is symptomatic SARS-CoV-2 infection, and each agent will be independently evaluated in real time when the required number of events occurs. Presently, three agents are approved in the platform: intranasal niclosamide, nasal and inhaled ciclesonide and intravenous sotrovimab. DISCUSSION Despite the introduction of vaccination, there remains a need for pre-exposure prophylactic agents against SARS-CoV-2. Several patient groups are more vulnerable to COVID-19 disease by virtue of underlying health conditions, treatments received or suboptimal responses to vaccination.

Abstract
This review presents an overview of the available literature regarding intranasal corticosteroids (INCs) for the treatment of allergic rhinitis (AR). Various treatment options exist for AR including INCs, antihistamines and leucotriene antagonists. INCs are considered to be the most effective therapy for moderate-to-severe AR, as they are effective against nasal and ocular symptoms and improve quality of life. Their safety has been widely observed. INCs are effective and safe for short-term use. Local adverse events are observed but generally well-tolerated. The occurrence of (serious) systemic adverse events is unlikely but cannot be ruled out. There is a lack of long-term safety data. INC may cause serious eye complications. The risk of INCs on the hypothalamic-pituitary-adrenal axis, on bone mineral density reduction or osteoporosis and on growth in children, should be considered during treatment. Pharmacological characteristics of INCs (e.g. the mode of action and pharmacokinetics) are well known and described. We sought to gain insight into whether specific properties affect the efficacy and safety of INCs, including nasal particle deposition, which the administration technique affects. However, advances are lacking regarding the improved understanding of the effect of particle deposition on efficacy and safety and the effect of the administration technique. This review emphasizes the gaps in knowledge regarding this subject. Advances in research and health care are necessary to improve care for patients with AR.

Abstract
Allergic rhinitis (AR), the most common chronic disease in childhood is often ignored, misdiagnosed and/or mistreated. Undertreated AR impairs quality of life, exacerbates asthma and is a major factor in asthma development. It can involve the nose itself, as well as the organs connected with the nose manifesting a variety of symptoms. Evidence-based guidelines for AR therapy improve disease control. Recently, paediatric AR guidelines have been published by the European Academy of Allergy and Clinical Immunology and are available online, as are a patient care pathway for children with AR and asthma from the Royal College of Paediatrics and Child Health. Management involves diagnosis, followed by avoidance of relevant allergens, with additional pharmacotherapy needed for most sufferers. This ranges, according to severity, from saline sprays, through non-sedating antihistamines, oral or topical, with minimally bioavailable intranasal corticosteroids for moderate/severe disease, possibly plus additional antihistamine or antileukotriene. The concept of rhinitis control is emerging, but there is no universally accepted definition. Where pharmacotherapy fails, allergen-specific immunotherapy, which is uniquely able to alter long-term disease outcomes, should be considered. The subcutaneous form (subcutaneous immunotherapy) in children has been underused because of concerns regarding safety and acceptability of injections. Sublingual immunotherapy is both efficacious and safe for grass pollen allergy. Further studies on other allergens in children are needed. Patient, carer and practitioner education into AR and its treatment are a vital part of management.

Abstract
The strong epidemiologic and pathophysiologic link between allergic rhinitis (AR) and asthma has led to the concept of 'united airways disease' or 'respiratory allergy', implying that allergy, in its widest sense, underlies this clinical syndrome. Progression from AR to asthma is frequent and part of the 'atopic march'. Since pediatric immune responses are more adaptable and therefore may be more amenable to treatment, interventions at early childhood are characterized by a higher chance to affect the natural history of respiratory allergy. Although current treatments are quite effective in alleviating respiratory allergy symptoms, it has proven much more difficult to confirm any influence on the progression of the disease. Much more promising is the field of specific allergen immunotherapy, where current evidence, although not yet of ideal robustness, points towards a disease-modifying effect. In addition, newer or emerging, possibly more effective or more targeted interventions are promising in the preventive sense.

Abstract
Given the relationship between allergic rhinitis (AR) and asthma, it can be hypothesized that reducing inflammation in the upper airway with intranasal corticosteroid (INCS) medications may improve asthma outcomes. The goal of this study was to perform a systematic review with meta-analysis of the efficacy of INCS medications on asthma outcomes in patients with AR and asthma. Asthma-specific outcomes from randomized, controlled studies evaluating INCS medications in patients with AR were evaluated, including studies that compared INCS sprays to placebo, INCS sprays plus orally inhaled corticosteroids to orally inhaled corticosteroids alone, and nasally inhaled corticosteroids to placebo. Sufficient data for meta-analysis were retrieved for 18 trials with a total of 2162 patients. Asthma outcomes included pulmonary function, bronchial reactivity, asthma symptom scores, asthma-specific quality of life, and rescue medication use. The subgroup of studies comparing INCS spray to placebo had significant improvements in FEV1 (SMD = 0.31; 95% CI, 0.04-0.58), bronchial challenge (SMD = 0.46; 95% CI, 0.12-0.79), asthma symptom scores (SMD = -0.42; 95% CI, -0.53 to -0.30), and rescue medication use (SMD = -0.29; 95% CI, -0.58 to -0.01). Nasal inhalation of corticosteroids significantly improved morning and evening peak expiratory flow. There were no significant changes in asthma outcomes with the addition of INCS spray to orally inhaled corticosteroids. Thus, the results of this meta-analysis demonstrated that intranasal corticosteroid medications significantly improve some asthma-specific outcome measures in patients suffering from both AR and asthma. This effect was most pronounced with INCS sprays when patients were not on orally inhaled corticosteroids, or when corticosteroid medications were inhaled through the nose into the lungs. Overall, intranasal corticosteroid medications improve some asthma-specific outcome measures in patients with both AR and asthma. Further research is needed to clarify the role of INCS sprays as asthma-specific therapy, as well as the role of the nasal inhalation technique as a monotherapy in patients suffering from both asthma and AR.

Abstract
Rhinitis is a common problem in childhood and adolescence and impacts negatively on physical, social and psychological well-being. This position paper, prepared by the European Academy of Allergy and Clinical Immunology Taskforce on Rhinitis in Children, aims to provide evidence-based recommendations for the diagnosis and therapy of paediatric rhinitis. Rhinitis is characterized by at least two nasal symptoms: rhinorrhoea, blockage, sneezing or itching. It is classified as allergic rhinitis, infectious rhinitis and nonallergic, noninfectious rhinitis. Similar symptoms may occur with other conditions such as adenoidal hypertrophy, septal deviation and nasal polyps. Examination by anterior rhinoscopy and allergy tests may help to substantiate a diagnosis of allergic rhinitis. Avoidance of relevant allergens may be helpful for allergic rhinitis (AR). Oral and intranasal antihistamines and nasal corticosteroids are both appropriate for first-line AR treatment although the latter are more effective. Once-daily forms of corticosteroids are preferred given their improved safety profile. Potentially useful add-on therapies for AR include oral leukotriene receptor antagonists, short bursts of a nasal decongestant, saline douches and nasal anticholinergics. Allergen-specific immunotherapy is helpful in IgE-mediated AR and may prevent the progression of allergic disease. There are still a number of areas that need to be clarified in the management of rhinitis in children and adolescents.

Abstract
BACKGROUND Allergic rhinitis (AR) is a common pediatric problem that significantly affects sleep, learning, performance, and quality of life. In addition, it is associated with significant comorbidities and complications. OBJECTIVE The aim was to provide an update on the epidemiology, comorbidities, pathophysiology, current treatment, and future direction of pediatric AR. METHODS Literature reviews in each of these areas were conducted, and the results were incorporated. RESULTS The prevalence of AR is increasing in the pediatric population and is associated with significant morbidity, comorbidities, and complications. The mainstay of current treatment strategies includes allergen avoidance, pharmacotherapy, and allergen specific immunotherapy. CONCLUSIONS In the future, diagnosis will be improved by microarrayed recombinant allergen testing and therapy will be expanded to include emerging treatments such as sublingual immunotherapy and combination products.

Abstract
BACKGROUND Allergic rhinitis frequently occurs as a comorbid condition in asthmatic people, suggesting that the upper and lower airways may be immunologically linked. Our research group has developed an experimental aeroallergen model of asthma in cats. We hypothesized that aeroallergen sensitization and challenge would induce morphologic changes in the nasal airways of cats that mimic those observed in the bronchial airways. METHODS Five mixed breed cats were sensitized to Bermuda grass allergen and then serially challenged with aerosolized Bermuda grass allergen to induce an asthmatic phenotype. Four control cats were similarly treated with saline vehicle. Nasal tissues and lungs were processed for histopathological and morphometric analyses. RESULTS Eosinophilic inflammation, epithelial hypertrophy and mucous cell metaplasia were observed along the pulmonary axial airway mucosa of allergen-sensitized (asthmatic) cats. Mild eosinophilic inflammation was observed in the nasal airways of asthmatic cats. This alteration was confined primarily to the anterior nasal cavity, resulting in an increase in tissue eosinophils at this site compared to controls (p < 0.05). A marked increase in tissue mast cells was observed throughout all regions of the nasal airways of asthmatic cats compared to control cats (p < 0.05). There was no difference in intraepithelial mucosubstances between the nasal airways of controls and asthmatic cats. There was no correlation between upper and lower airway eosinophils or mast cells. CONCLUSION Cats with experimentally induced asthma exhibit morphologic changes in the nasal airways that are distinct from the alterations observed in the lungs. These results are similar to those observed in people with comorbid asthma and allergic rhinitis.

Abstract
OBJECTIVES We compared the results of nasal sound spectral analysis (NSSA) with the results of peak nasal inspiratory flow (PNIF) testing and use of a visual analog scale in patients with allergic rhinitis with nasal obstruction. METHODS We performed NSSA and PNIF testing on 38 patients with allergic rhinitis and 35 healthy subjects. A diagnostic decongestion test was performed on the patients (not on the control subjects). Twenty minutes after decongestant was sprayed into the nostrils, NSSA and PNIF testing were performed again. RESULTS There was a significant difference in the PNIF values and the nasal inspiratory sound intensities before and after decongestion (p < 0.001). There was a correlation between the NSSA results at the frequency range of 2 to 4 kHz and the PNIF results. The calculated cutoffs between normal and pathological values were 14.8 dB (2 to 4 kHz) for NSSA and 116 +/- 14.1 L/min for PNIF testing. No significant differences were computed between NSSA and PNIF testing in terms of sensitivity (0.71 versus 0.76) or specificity (0.74 versus 0.80). CONCLUSIONS Use of NSSA and PNIF testing together for assessment of nasal obstruction in allergic rhinitis provides clinical relevance in that it allows a fair degree of reliability. Such testing can be performed as a surrogate for rhinomanometry.

Abstract
BACKGROUND Allergic rhinitis, especially when persistent (PER) and associated with asthma heavily impairs patients' quality of life (QoL). OBJECTIVE This study assessed the effect of mometasone furoate nasal spray (MFNS) on the QoL of patients with PER and asthma, using the Rhinasthma questionnaire (EUDRACT n. 2007-004683-45). METHODS Patients with moderate/severe PER and intermittent asthma were randomized to MFNS (alcohol-free) 200 μg/day or placebo for 28 days. Rhinasthma was completed at baseline and at weeks 2 and 4. The total five symptom score (T5SS) for rhinitis, the asthma symptom score and the sum of the two [global symptoms score (GSS)] were recorded daily. The primary outcome was the change in the Rhinasthma global summary (GS) at the end of treatment. Secondary end-points were (a) the change from baseline to end of treatment of each Rhinasthma factor: upper airways (UAs), lower airways (LAs) and respiratory allergy impact; (b) the change from baseline to end of treatment of the T5SS and of the GSS and (c) the use of rescue medication. RESULTS Fifty-two adults were randomized. Compared with placebo, MFNS produced a significant change in the Rhinasthma GS (-10.4 vs. 0.4; P<0.01). MFNS also achieved a significant improvement of the UA (-16.6 vs. 0.1; P<0.001), LA (-10.8 vs. 1.1; P<0.001) and GSS (-6.7 vs. -3.1; P=0.019). The change of the T5SS was greater in the MFNS group but did not reach statistical significance. CONCLUSION In patients with PER rhinitis and intermittent asthma, MFNS improves the QoL and the burden of respiratory symptoms. Treating rhinitis may affect the asthma-related QoL.

Abstract
BACKGROUND The mechanisms through which rhinitis affects asthma have not been completely elucidated. We explored whether the effect of nasal treatment on asthma control and respiratory-related quality of life (HRQoL) is mediated by inflammatory changes of the upper and lower airways. METHODS Allergic rhinitics with mild asthma were randomized to a 14-day treatment period with either nasal budesonide 100 μg, 1 puff per nostril twice a day, or placebo. Clinical, functional, and biological evaluations were performed before and after treatment. RESULTS Twenty subjects (M/F: 10/10; age: 31 ± 15 years; mean ± SD) were enrolled, and a total of 17 individuals completely participated in the study. Lung function was within the normal range. The total asthma control test (ACT) score was 20 ± 5.3 and the RHINASTHMA Global Summary (GS) was 44 ± 15. The percentage proportion of eosinophils in nasal lavage was 9.9% and significantly correlated with spirometric parameters reflecting peripheral airway function (for FEF(50): r = 0.48, p = .03; for FEF(25): r = 0.47, p = .03). The pH of the exhaled breath condensate (EBC) was 7.33 ± 0.4. After nasal treatment, the percentage proportion of eosinophils fell significantly (p = .002), and changes in percentage proportion of eosinophils were associated with changes both in the ACT score (r = 0.76, p = .04) and in the RHINASTHMA GS (r = 0.77, p = .02). The increase in the pH of the EBC was not associated with changes in the ACT score or with the RHINASTHMA GS. CONCLUSIONS These findings confirm that, in subjects with allergic rhinitis with mild asthma, nasal inflammation impacts on asthma control and HRQoL. The improved control of respiratory symptoms obtained with nasal corticosteroids seems to be mediated by functional changes in the peripheral airways.

Abstract
Rhinitis and asthma are often associated and the two disorders interact at various levels. Rhinitis typically precedes the development of asthma and can contribute to unsatisfactory asthma control. The presence and type of asthma is influenced by sensitization, and the duration and severity of allergic rhinitis. Nasal symptoms, airflow and markers of inflammation directly correlate with lower airway involvement. Local tissue factors, such as microbial stimuli and systemic inflammatory mechanisms, play a role in the clinical expression of the allergic airway syndrome. There is increasing evidence that suggests a major involvement of airway epithelial cells in the pathogenesis of both asthma and allergic rhinitis. Even in patients with rhinitis who do not have asthma, subclinical changes in the lower airways and inflammatory mediators can be detected. The pathogenic role of paranasal sinus infections in respiratory allergy has been better elucidated but there remains a need for further research. Treatment of established rhinitis may affect asthma control and could have some impact on airway obstruction, but a direct effect of rhinitis therapy on lower airway inflammation remains to be clearly established.

Abstract
Persistent allergic rhinitis (AR) and asthma constitute a common comorbidity. Combined treatment is recommended by prescribing intranasal plus oral inhaled corticosteroids. This study was carried out to assess the efficacy of an alternative regimen to treat this condition. All recruited patients suffered from persistent AR and asthma. Diagnosis and classification of AR and asthma were based on international guidelines. The experimental group received fluticasone propionate (FP), 500microg/day during six weeks, inhaled exclusively through the nose using a valved large volume spacer attached to a face mask. The comparison group also received the same dose of orally inhaled FP, during the same time period, plus intranasal aqueous fluticasone, 200microg/day. There were no statistical differences between both groups regarding AR and asthma severity, clinical scores, acoustic rhinometry, lung function, and FeNO upon admission and during the follow up period. Intragroup analysis demonstrated a significant improvement for allergic rhinitis and asthma scores as well as for FeNO from admission to the sixth week (p<0.01) in both groups. Results suggest that exclusive nasally inhaled fluticasone propionate should be considered as an alternative step in the management of patients suffering from AR and asthma comorbidity.

Abstract
Allergic asthma and rhinitis are highly prevalent diseases. Although they are diagnosed and treated separately, many patients suffer from both. There is data suggesting that they can be considered as manifestations of the same disease or syndrome, but in different locations. This article discusses the evidence favouring a joint clinical approach, and the main therapeutic tactics to achieve disease control; tries to establish the importance of isolated and adjuvant treatment of rhinitis and asthma, highlighting a small number of clinical studies regarding the subject; and indicates points for future research.

Abstract
Allergic rhinitis (AR) and asthma coexist frequently and a dual treatment is recommended by prescribing topical nasal plus oral inhaled corticosteroids. The purpose of this study was to assess the efficacy of a nasally inhaled corticosteroid aiming at concomitant control of AR and asthma. A controlled trial was conducted among 60 patients with AR and asthma, aged 6-18 years, who were randomized into two groups. During 8 weeks, the experimental group (30 patients) received exclusively fluticasone propionate hydrofluoroalkane (FP-HFA) inhaled through the nose (mouth closed) using a large volume spacer attached to a face mask. The comparison group (30 patients) received a nasal spray of isotonic saline plus oral inhalation of FP-HFA through a mouthpiece attached to the same spacer. Clinical scores for AR and asthma, nasal inspiratory peak flow (NIPF), and spirometry were assessed by blinded observers. There was a significant improvement in AR scores and NIPF in the experimental group (P <or= 0.01) up to week 8, when a worsening was observed after the intervention was interrupted. Asthma symptoms score, forced expiratory volume (FEV)(1), and FEF(25-75%) were not statistically different between groups at the baseline visit or along follow-up visits (P >or= 0.20). Prebronchodilator FEV(1) (% predicted value) improved by 10% in both groups, comparing values at inclusion with those obtained at the end of follow up. Our results suggest that nasally inhaled FP-HFA through a spacer may control AR and asthma in children and adolescents. This approach is likely to result in higher compliance, lower costs, and fewer side effects.

Abstract
BACKGROUND Allergic rhinitis is a very common chronic illness affecting 10% to 40% of children worldwide. There has been a significant increase in prevalence among children over the last two decades and this increase has been accompanied by a parallel increase in comorbid illnesses such as asthma. OBJECTIVES To evaluate the therapeutic effectiveness and adverse event profiles of topical nasal steroids for intermittent and persistent allergic rhinitis in children. SEARCH STRATEGY We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 3, 2005), MEDLINE (1950 onwards) and EMBASE (1974 onwards) on 5(th) September 2005. CINAHL, mRCT(a meta-database of controlled trials), NRR (the National Research Register), LILACS, MedCarib, KOREAMED, IndMed, Samed, Panteleimon, Zetoc, ISI Proceedings, the GlaxoSmithKline Clinical Trials Database and the websites of AstraZeneca, Schering Plough and Aventis were also searched. SELECTION CRITERIA Randomised controlled trials comparing topical nasal steroid preparations against each other or placebo, prescribed for allergic rhinitis in children. DATA COLLECTION AND ANALYSIS Two authors independently assessed trial quality and extracted data from the included trials. The limited and variable quality of reported data precluded any pooling of results and only a descriptive summary is presented. MAIN RESULTS Three trials involving a total of 79 participants were included. All three trials, which compared topical nasal steroids against placebo for perennial rhinitis, provided some, albeit limited data, relevant to our primary outcomes; but in two of the trials the data analysis was flawed and in the third trial it was incomprehensible. None of the trials provided data relevant to our secondary outcomes. There were no adverse events reported from any of the interventions. AUTHORS' CONCLUSIONS The three included trials provided some weak and unreliable evidence for the effectiveness of Beconase(R) and flunisolide used topically intranasally for the treatment of intermittent and persistent allergic rhinitis in children. The reduction of severity in symptoms as assessed by the trialists could not be confirmed with the data provided and decisions on the use of these medications should, until such time as more robust evidence is available, be guided by the physician's clinical experience and patients' individual circumstances and preferences.

Abstract
STUDY OBJECTIVES Rhinitis and asthma are considered to be synchronic or sequential forms of the same allergic syndrome. Treating the inflammation associated with allergic rhinitis influences the control of asthma. However, few studies have investigated the effect of treating perennial rhinitis on persistent asthma and vice versa. We determined the effects of inhaled or topical nasal beclomethasone dipropionate (BDP) administered separately or in combination on the control of asthma and bronchial hyperresponsiveness (BHR) in patients with the rhinitis/asthma association. DESIGN A double-blind, parallel, three-group study. SETTING Outpatient clinic of Pulmonary Division/Heart Institute (InCor) and the Division of General Internal Medicine, University of Sao Paulo Medical School, Sao Paulo, Brazil. PATIENTS Seventy-four patients with mild-to-moderate asthma and allergic rhinitis (median age, 25 years). INTERVENTIONS Patients received nasal or inhaled BDP separately or in combination for 16 weeks after a 2-week placebo run-in period. MEASUREMENTS AND RESULTS Nasal and pulmonary symptoms, as well as pulmonary function and BHR, were compared among the three groups after 4 weeks and 16 weeks of treatment. Patients in all three groups demonstrated a progressive and significant decrease in nasal and pulmonary symptoms, which started after 4 weeks (p < 0.05) and continued through the end of treatment (p < 0.001). Clinical improvement was similar and parallel in the three groups. Asthma-related morbidity, evaluated by quantifying absence from work, emergency department visits, and nighttime awakenings, also decreased in the three groups (p < 0.05). CONCLUSIONS Failure to consider treatment of rhinitis as essential to asthma management might impair clinical control of asthma. Furthermore, these data suggest that asthma and rhinitis in some patients can be controlled by the exclusive use of nasal medication.

Abstract
BACKGROUND Allergic rhinitis (AR) and asthma often coexist and may represent two manifestations of the same disease recently named combined AR and asthma syndrome (CARAS). AIM To review the common pathophysiology of combined AR and asthma and to investigate the efficacy of intranasal corticosteroids (INCS). METHODS Medline was used to identify articles relevant to mechanisms. A Cochrane systematic review was performed to assess the efficacy of INCS in CARAS. RESULTS There is cross-talk, evidence of a common inflammatory response in both sites, linked by a systemic component. The efficacy of anti-inflammatory INCS on asthma outcomes was assessed in a systematic review of 12 randomized controlled trials involving 425 subjects. After INCS there were non-significant trends for improvement in asthma symptom score (standardized mean difference (SMD) of 0.61; P=0.07), forced expiratory volume in 1 s (SMD of 0.31; P=0.08), and morning peak expiratory flow (weighted mean difference of 36.51; P=0.06). There was no impact on methacholine airways responsiveness (SMD of -0.20; P=0.4). The review identified two promising new treatment options in united airway disease such as INCS as monotherapy in rhinitis and mild asthma, and a combined intranasal and intrabronchial corticosteroid (IBCS) deposition technique. CONCLUSION Common mucosal inflammatory responses occur in CARAS. This systematic review shows trends for a benefit of INCS in CARAS, but recognizes that more research is needed. At this stage, the current best practice is to treat asthma conventionally with IBCS with or without beta(2)-agonist and to add INCS to improve specific rhinitis symptoms.

Abstract
Asthma and allergic rhinitis (AR) form a well-recognized comorbidity. This study aims at assessing the efficacy of nasally inhaled beclomethasone dipropionate (BDP) in their simultaneous treatment. A randomized controlled trial was conducted with 78 allergic rhinitis and asthma patients aged 5-17 years. Seventy-five individuals completed the study. During 8 weeks, 38 subjects received BDP-CFC aerosol (>or= 500 mcg/day) exclusively via nasal inhalation through a facemask attached to a plastic valved spacer. The control group (37 patients) received 200 mcg/day of aqueous intranasal beclomethasone plus oral inhalation of BDP-CFC (>or= 500 mcg/day) through a mouthpiece connected to the same spacer. Primary outcomes analyzed in order to assess the response to treatment were clinical scoring for allergic rhinitis and measurements of nasal inspiratory peak flow (NIPF). AR clinical scoring and NIPF did not differ in the two groups at admission or at nearly all follow-up visits. Nasal inhalation of beclomethasone dipropionate provides AR symptom relief while maintaining control of asthma by delivering it to the lungs. Therefore, this therapeutic strategy might be considered for patients suffering from this comorbidity, especially in low-resource countries, since it is less expensive than the conventional treatment.

Abstract
BACKGROUND Allergic rhinitis and asthma are mediated by similar allergic mechanisms. They may represent two manifestations of the same united airway disease and therefore intranasal corticosteroids (INCS) could improve asthma. Nevertheless none of the asthma guidelines have advocated intranasal corticosteroids for asthma. OBJECTIVES To assess the efficacy of intranasal corticosteroids on asthma outcomes in people with rhinitis and asthma. SEARCH STRATEGY We searched the Cochrane Airways Group trials register, the Cochrane Central Register of Controlled Trials (Issue 1, 2003), MEDLINE and reference lists of articles. We also contacted researchers in the field. Last search updated in March 2003. SELECTION CRITERIA Randomised controlled trials comparing intranasal corticosteroids to intranasal placebo or to other traditional asthma treatments were included. Intrabronchial corticosteroids were not allowed but a device combining intranasal and intrabronchial corticosteroid was considered as being a primary INCS technique and was therefore also compared to placebo. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed trial quality and extracted data. Study authors were contacted for additional information. Quality assessment for the 14 eligible studies was performed using the Jadad score and by ranking allocation concealment. Statistical analysis for continuous data was done by weighted mean difference or standardised mean difference. MAIN RESULTS Fourteen trials involving 477 people were included. Meta-analysis for asthma outcomes failed to show a statistically significant benefit of INCS in asthma. However, for symptom scores and forced expiratory volume in one second, the trend favoured a beneficial effect of INCS. For asthma symptom scores (two parallel studies), the standardised mean difference was 0.61 (95% confidence interval (CI) -0.04 to 1.26). Meta-analysis for forced expiratory volume in one second (five parallel studies) gave a standardised mean difference of 0.31 (95% CI -0.04 to 0.65). In the parallel studies, meta-analysis of peak expiratory flow gave a standardised mean difference of -0.10 Litres/min (95% CI -0.55 to 0.35) for mean peak flow (three studies). Meta-analysis for methacholine airway responsiveness (three parallel studies) showed a standardised mean difference of -0.20 (-95% CI 0.64 to 0.24). REVIEWER'S CONCLUSIONS Intranasal corticosteroids were well tolerated. While INCS tended to improve asthma symptoms and forced expiratory volume in one second, the results did not reach significance. The combination of intranasal plus intrabronchial corticosteroids should remain the current clinical practice until more research is done.

Abstract
Antihistamines and inhaled glucocorticoids, which can be targeted toward multiple points in the "allergic cascade" underlying allergic rhinitis and asthma, extend the promise of enhanced outcomes in children with allergic rhinitis, asthma, or both. Antihistamine therapy confers significant relief of subjective ratings of seasonal and perennial allergic symptoms (e.g., rhinorrhea, congestion, sneezing, pruritus), whereas topical steroids alleviate such discomfort while also improving objective anatomic and functional indices of nasal patency (e.g., nasal peak inspiratory flow). Youngsters with asthma also experience substantial clinical benefits from inhaled steroids, which improve objective measures of pulmonary function and reduce rescue beta 2-agonists for symptom management and quality-of-life enhancement. This paper reviews recent clinical findings on the role of antihistamines and topical corticosteroids in pediatric allergy and asthma management, as well as the favorable effects of these medications on both objective and subjective health outcomes.

Abstract
It is logical to look upon the nose and the bronchi as integrated parts of one 'united airway' and we would like to advance the hypothesis that optimal management of airway disease, caused by inhaled allergens, may necessitate control of inflammation in all parts of the airways. Nasal inflammation can aggravate asthma symptoms, and there is a rationale for giving intranasal anti-inflammatory treatment to patients with asthma. (i) Inhaled allergens are predominantly deposited in the nose, whether a patient suffers from rhinitis, asthma or both. (ii) Antigen presentation consequently takes place in the nose, and the response of the airway immune system is thus initiated in the nasal mucous membrane. (iii) Antigen presentation in the nose may possibly induce cell recruitment and activation not only in the nasal mucosa but also in the lower airways. (iv) Suppression of nasal inflammation may therefore be necessary for optimal management of asthma.
