Abstract
For clinicians involved in improving healthcare for patients with allergic and immunologic conditions, advocacy on a broader level through public outreach is key to advancing value-based care. In this article, we provide a toolkit of strategies and resources that can be used to raise public awareness of important issues through various mediums, including podcasts and social media, newspapers, testimonies, presentations, and interviews. A simple approach to effective media interactions is described using the acronym "RATIO," which stands for Research, Audience, Targeted topic, Interview rephrasing, and Optimism. The acronym also reminds the person who is presenting information that only a fraction of what is discussed will be recalled, and an even smaller proportion will be implemented. Key points should be made early. Examples of key talking points are provided for selected topics, including food allergy, anaphylaxis, asthma, rhinitis, and broader healthcare advocacy.

Sci Rep 2023; 13:13326. [PMID: 37587208 PMCID: PMC10432425 DOI: 10.1038/s41598-023-40489-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Accepted: 08/10/2023] [Indexed: 08/18/2023] Open
Abstract
Asthma and chronic obstructive pulmonary disease (COPD) are prevalent chronic respiratory disorders that cause significant morbidity and mortality. Some studies evaluated the use of inhaled unfractionated heparin (UFH) in the treatment of asthma and COPD. We aimed to synthesize the available evidence for the efficacy and safety of inhaled heparin in improving lung functions among asthmatic and COPD patients. A comprehensive search was performed using Pubmed, Embase, EBSCO, Scopus, Web of Science, Cochrane CENTRAL, WHO Clinical trials, clinicaltrials.gov, Iranian Clinical trials, Google Scholar, Research Gate, ProQuest Thesis, OVID, and medRxiv databases. Two independent reviewers included all pertinent articles according to PRISMA guidelines, and extract data independently. The two reviewers checked the quality of studies using the ROB2 tool. To determine the pooled effect estimate of the efficacy and safety of inhaled heparin, a meta-analysis was carried out using the R programming language. Publication bias was evaluated using Egger's regression test. The heterogeneity was explained using a meta-regression, and the quality of evidence was assessed by the GRADE approach. Twenty-six studies with a total of 581 patients were included in the qualitative analysis and 16 in the meta-analysis. The primary outcome was treatment success (improvement of lung function) that was measured by standardized mean differences (SMD) of the forced expiratory volume per second (FEV1) either per ml or percentage. Heparin has a large effect on both FEV1% and FEV1 ml when compared to the control group (SMD 2.7, 95% CI 1.00; 4.39; GRADE high, SMD 2.12, 95% CI - 1.49; 5.72: GRADE moderate, respectively). Secondary outcomes are other lung functions improving parameters such as PC20 (SMD 0.91, 95% CI - 0.15; 1.96). Meta-regression and subgroup analysis show that heparin type, dose, year of publication, study design, and quality of studies had a substantial effect. Regarding safety, inhaled heparin showed a good coagulation profile and mild tolerable side effects. Inhaled heparin showed improvement in lung functions either alone or when added to standard care. More large parallel RCTs are needed including COPD patients, children, and other types, and stages of asthmatic patients.

Abstract
Chronic respiratory diseases are prevalent medical conditions in dogs and cats requiring lifelong treatment. Mainstay of therapy for chronic inflammatory respiratory diseases are glucocorticoids. Concurrent treatment with bronchodilators may be necessary to control clinical signs sufficiently. Due to the successful use in people as well as subsequent reduction of adverse effects of long-term glucocorticoid therapy, inhalative therapy has become increasingly important in veterinary medicine as well. Primarily spacers or valved holding chambers, in combination with metered dose inhalers, are used in dogs and cats. The technical properties of these devices, as well as their use and maintenance will be described in the following article. Furthermore, the existing literature regarding efficacy of inhalative medications for therapy of chronic inflammatory airway diseases in dogs and cats will be summarized.

Abstract
International guidelines provide recommendations for a stepwise approach to the management of asthma in children 0-4 years old, 5-11 years old, and adolescents who are treated as adults. Therapy is aimed at two domains of control: current impairment and future risk. The long-term controller medications, inhaled corticosteroids (ICSs), ICSs in combination with long-acting β2 agonists, leukotriene receptor antagonists, and immunomodulators, exhibit different efficacies for these domains. The risk:benefit ratios of the available medications need to be carefully assessed. This review briefly presents the benefits and the potential risks of available asthma medications in children to assist the practitioner in the optimal use of asthma medications. Specifically, the systemic activity of the ICSs and how to minimize their effects on growth and adrenal activity are reviewed as well as other potential adverse effects. Dosing strategies such as intermittent therapy are also assessed.

Abstract
Objective To systematically review the literature and determine frequencies of adverse drug events (ADE) associated with pediatric asthma medications. Methods Following PRISMA guidelines, we systematically searched six bibliographic databases between January 1991 and January 2017. Study eligibility, data extraction and quality assessment were independently completed and verified by two reviewers. We included randomized control trials (RCT), case-control, cohort, or quasi-experimental studies where the primary objective was identifying ADE in children 1 month– 18 years old exposed to commercial asthma medications. The primary outcome was ADE frequency. Findings Our search identified 14,540 citations. 46 studies were included: 24 RCT, 15 cohort, 4 RCT pooled analyses, 1 case-control, 1 open-label trial and 1 quasi-experimental study. Studies examined the following drug classes: inhaled corticosteroids (ICS) (n = 24), short-acting beta-agonists (n = 10), long-acting beta-agonists (LABA) (n = 3), ICS + LABA (n = 3), Leukotriene Receptor Antagonists (n = 3) and others (n = 3). 29 studies occurred in North America, and 29 were industry funded. We report a detailed index of 406 ADE descriptions and frequencies organized by drug class. The majority of data focuses on ICS, with 174 ADE affecting 13 organ systems including adrenal and growth suppression. We observed serious ADE, although they were rare, with frequency ranging between 0.9–6% per drug. There were no confirmed deaths, except for 13 potential deaths in a LABA study including combined adult and pediatric participants. We identified substantial methodological concerns, particularly with identifying ADE and determining severity. No studies utilized available standardized causality, severity or preventability assessments. Conclusion The majority of studies focus on ICS, with adrenal and growth suppression described. Serious ADE are relatively uncommon, with no confirmed pediatric deaths. We identify substantial methodological concerns, highlighting need for standardization with future research examining pediatric asthma medication safety.

Abstract
El asma es la enfermedad crónica infantil más frecuente. El diagnóstico es fácil en la mayoría de las ocasiones por la aparición de episodios de disnea espiratoria con sibilancias reversibles espontáneamente o por el efecto de broncodilatadores. En el momento del diagnóstico, se requieren tres pruebas complementarias: las radiografías de tórax, las pruebas funcionales respiratorias y un estudio alergológico. El tratamiento de las exacerbaciones se basa en los beta2-adrenérgicos inhalados y, si es preciso, en la corticoterapia oral. El objetivo del tratamiento de fondo es mantener el control, prevenir las exacerbaciones y restaurar o mantener las funciones pulmonares normales. Se debe adaptar al nivel de control del asma y en él tiene un lugar destacado la corticoterapia inhalada y los broncodilatadores de acción prolongada. En los menores de tres años, el asma se diagnostica a partir de tres episodios de sibilancias. Se debe buscar la presencia de antecedentes particulares, de manifestaciones atípicas o persistentes y de anomalías en la radiografía de tórax para descartar las demás causas de manifestaciones sibilantes recidivantes. Cuando es necesario un tratamiento de fondo, se basa en la corticoterapia inhalada. Las cohortes prospectivas han permitido demostrar que la atopia, la gravedad clínica y la persistencia de una obstrucción clínica son los factores principales tanto de la persistencia como de la gravedad del asma durante la vida.

Abstract
Background Long-term inhaled corticosteroids (ICS) may reduce growth velocity and final height of children with asthma. We aimed to evaluate the association between ICS use of >12 months and growth. Methods We initially searched MEDLINE and EMBASE in July 2013, followed by a PubMed search updated to December 2014. We selected RCTs and controlled observational studies of ICS use in patients with asthma. We conducted random effects meta-analysis of mean differences in growth velocity (cm/year) or final height (cm) between groups. Heterogeneity was assessed using the I2 statistic. Results We found 23 relevant studies (twenty RCTs and three observational studies) after screening 1882 hits. Meta-analysis of 16 RCTs showed that ICS use significantly reduced growth velocity at one year follow-up (mean difference -0.48 cm/year (95% CI -0.66 to -0.29)). There was evidence of a dose-response effect in three RCTs. Final adult height showed a mean reduction of -1.20 cm (95% CI -1.90 cm to -0.50 cm) with budesonide versus placebo in a high quality RCT. Meta-analysis of two lower quality observational studies revealed uncertainty in the association between ICS use and final adult height, pooled mean difference -0.85 cm (95% CI -3.35 to 1.65). Conclusion Use of ICS for >12 months in children with asthma has a limited impact on annual growth velocity. In ICS users, there is a slight reduction of about a centimeter in final adult height, which when interpreted in the context of average adult height in England (175 cm for men and 161 cm for women), represents a 0.7% reduction compared to non-ICS users.

Abstract
OBJECTIVE The clinical relevance of lower basal cortisol levels in children with asthma is unclear. We compared the salivary cortisol response after a standardized exercise test in children with asthma versus the salivary cortisol response in healthy children. METHODS Nineteen prepubertal children with asthma and 20 prepubertal healthy children performed a standardized exercise test twice. Salivary cortisol levels were determined before exercise and immediately and 15 min after exercise. Morning salivary cortisol levels were determined from saliva collected at home. RESULTS Salivary cortisol levels increased in 84.2% of the healthy children compared to 35.0% in children with asthma after the 20-m shuttle-run test. Median increase in salivary cortisol levels was 200.3% [95% confidence interval (CI), 141.8-346.1] in healthy children compared to 89.8% (95% CI, 56.9-181.6) in children with asthma. The response was not related to the morning salivary cortisol level or maintenance dose of inhaled corticosteroids. The mean time to exhaustion of both shuttle-run tests was significantly shorter in children with asthma (mean difference 1.4 min; 95% CI, 0.7-2.3). None of the children had to stop because of dyspnea. CONCLUSION Our study demonstrates that children with asthma using a maintenance dose of inhaled corticosteroids (ICS) have an attenuated salivary cortisol response compared with healthy children.

Abstract
Inhaled corticosteroids (ICS) are recommended as the first-line therapy for children with persistent asthma. These agents are particularly effective in reducing underlying airway inflammation, improving lung function, decreasing airway hyper-reactivity, and reducing intensity of symptoms in asthmatics. Chronic diseases, such as asthma, have growth-suppressing effects independent of the treatment, which inevitably complicates growth studies. One year studies showed a small, dose-dependent effect of most ICS on childhood growth, with some differences across various ICS molecules, and across individual children. Some ICS at the doses studied did not affect childhood growth when rigorous study designs were used. Most studies did not conform completely with the FDA guidance. The data on effects of childhood ICS use on final adult height are conflicting, but one recent well-designed study showed such an effect, clearly warranting additional studies. In spite of these measurable effects of ICS on childhood growth, it is important to understand that the safety profile of all ICS preparations, with focal anti-inflammatory effects on the lung, is significantly better than oral glucocorticoids.

Abstract
OBJECTIVE To evaluate the effect of orally and nasally inhaled corticosteroids (ICS) on final adult height in pediatric patients with mild to moderate persistent asthma and allergic rhinitis. DATA SOURCES MEDLINE (1975-April 2013), Cochrane Library (through 2012), and International Pharmaceutical Abstracts (1975-April 2013) were searched for prospective clinical trials assessing the effects of orally or intranasally ICS use on growth in pediatric patients with asthma or allergic rhinitis using the terms inhaled/intranasal corticosteroid, linear growth, height, and asthma or allergic rhinitis. STUDY SELECTION AND DATA EXTRACTION Eligible articles included double-blind, randomized, placebo-controlled studies of at least 1 year with growth velocity or height as the primary outcome. DATA SYNTHESIS Seven trials and 1 follow-up study analyzing the effects of orally ICSs were examined. Of these studies, 4 found a delay in growth in at least 1 subset of its participants of approximately 1 cm, 1 study found a decrease in final adult height of 1.2 cm, and 3 studies found no effect. Of the 4 studies examining nasally ICS, 1 found evidence of growth delay in a subgroup using supratherapeutic dosing. There are conflicting data on whether ICS use causes long-term growth reduction in pediatric patients. The concern surrounding their long-term use including a potential delay or decrease in growth may result in underuse and potential mismanagement of persistent asthma and/or allergic rhinitis. Patients should be treated with the lowest effective corticosteroid dose to achieve symptomatic control while minimizing excessive systemic effects. Orally ICS use may cause a delay in growth, but a decrease in final adult height (1.2 cm) has been documented in only one study. This single report should not preclude daily use of inhaled corticosteroids if needed to decrease the morbidity and mortality associated with pediatric reactive airway disease. CONCLUSIONS Continued studies on the systemic effects of ICS are required before truly understanding the class's effect on growth in pediatric patients with asthma and allergic rhinitis. What is understood, however, is the detriment and potential danger of mismanaged asthma care.

Abstract
Eosinophilic esophagitis, an increasingly recognized chronic inflammatory disorder isolated to the esophagus, is triggered by an abnormal allergic response to dietary antigens. Current treatment includes swallowed topical steroids and dietary modification, which aim to resolve symptoms and prevent long-term complications such as formation of strictures. The dietary approach has become more widely accepted because long-term steroid therapy is associated with potential risks. Dietary treatment includes elemental and elimination diets. An exclusive elemental diet, which requires replacement of all intact protein with amino acid-based formula, offers the best response of all available therapies, with remission in up to 96% of subjects proving it to be superior to all other available therapies including topical steroids. However, compliance with this approach is challenging because of poor taste and monotony. The high cost of formula and the associated psychosocial problems are additional drawbacks of this approach. Empiric and allergy test-directed elimination diets have gained popularity given that elimination of a limited number of foods is much easier and as such is more readily acceptable. There is a growing body of literature supporting this type of therapy in both children and adults. This paper reviews the evidence for all types of dietary therapy in eosinophilic esophagitis.

Abstract
BACKGROUND Asthma guidelines recommend prescription of inhaled corticosteroids at a reduced dosage in children compared to older patients in order to minimize the systemic exposure and risk of unwanted side effects. In children, pressurized metered dose inhalers (pMDI) are recommended in combination with a valved holding chamber (VHC) to overcome the problem of coordinating inhalation with actuation. However, the influence of age and body size on the systemic exposure of drugs to be administered via a pMDI with VHC is still not fully elucidated. Therefore, we aimed to compare the systemic exposure to the active ingredients of a fixed combination of beclometasone-dipropionate/formoterol-fumarate administered via pMDI with VHC in children, adolescents and adults. METHODS The pharmacokinetics of formoterol and beclometasone-17-monopropionate (active metabolite of beclometasone-dipropionate) was evaluated over 8 h from three studies, each performed in a different age and body size group. Children (7-11 years, n = 20), adolescents (12-17 years, n = 29) and adults (≥18 years, n = 24) received a single dose of beclometasone/formoterol (children: 200 μg/24 μg, adolescents and adults: 400 μg/24 μg) via pMDI with AeroChamber Plus™. RESULTS The systemic exposure in children in comparison to adolescents was equivalent for formoterol while it was halved for beclometasone-17-monopropionate in accordance with the halved dose of beclometasone administered in children (90% CIs within 0.8-1.25 for formoterol and 0.4-0.625 for beclometasone-17-monopropionate). The systemic exposure to beclometasone-17-monopropionate and formoterol was equivalent between adolescents and adults. CONCLUSIONS The systemic exposure to the active ingredients of a fixed dose combination of beclometasone/formoterol administered via pMDI with AeroChamber Plus™ correlates with the nominal dose independently of patient age and body size. Thus, dose reduction in relation to age when using a pMDI with VHC may be unnecessary for reducing the systemic exposure in children.

Abstract
Potent, topically active corticosteroids with minimum systemic activity have fewer adverse effects than do systemic corticosteroids, and can control both asthma and allergic rhinitis when given in recommended doses. However, study findings show that children with asthma receiving budesonide and beclometasone dipropionate have decreased linear growth, and that children who receive long-term inhaled corticosteroid therapy for asthma have height deficits 1-2 years after treatment initiation that persist into adulthood. The effects of inhaled corticosteroids on growth seem to be dependent on both dose and duration; the degree of systemic effects is dependent on pharmacokinetic properties (ie, absorption, distribution, and elimination), whereas the effective dose delivered is dependent on the delivery system and potency of the molecule. The effects of corticosteroids on bone mineral density in children seem to be more amenable to intervention; long-term therapy with inhaled corticosteroid therapy is safer than frequent bursts of oral corticosteroids on bone mineral accretion in this regard. Importantly, adequate nutrition (particularly sufficient intake of calcium and vitamin D) should prevent or blunt the effects of corticosteroids on bone mineral density. The potential adverse effects of inhaled corticosteroids need to be weighed against the large and well established benefit of these drugs to control persistent asthma. To minimise any adverse effects, treatment with inhaled corticosteroids should always aim to reach the lowest effective dose that gives the patient good asthma control.

Abstract
Inhaled corticosteroids (ICS) are the guideline-preferred preventative therapy for persistent asthma of all severity levels and for all ages, including children. While these drugs are unquestionably efficacious, concerns of adverse systemic effects limit patient compliance with treatment regimens and thus the attainable benefits. Suppression of bone growth, bone density, and HPA axis function, in addition to cataract formation and elevated intraocular pressure/glaucoma, have been associated with ICS use. This review will focus on recent developments in the safety and efficacy of ICS as compared to oral CS corticosteroids and the achievement of a balance between risk and benefit in optimizing ICS therapy.

Abstract
Inhaled corticosteroids (ICSs) are used extensively in the treatment of asthma and chronic obstructive pulmonary disease (COPD) due to their broad antiinflammatory effects. They improve lung function, symptoms, and quality of life and reduce exacerbations in both conditions but do not alter the progression of disease. They decrease mortality in asthma but not COPD. The available ICSs vary in their therapeutic index and potency. Although ICSs are used in all age groups, younger and smaller children may be at a greater risk for adverse systemic effects because they can receive higher mg/kg doses of ICSs compared with older children. Most of the benefit from ICSs occurs in the low to medium dose range. Minimal additional improvement is seen with higher doses, although some patients may benefit from higher doses. Although ICSs are the preferred agents for managing persistent asthma in all ages, their benefit in COPD is more controversial. When used appropriately, ICSs have few adverse events at low to medium doses, but risk increases with high-dose ICSs. Although several new drugs are being developed and evaluated, it is unlikely that any of these new medications will replace ICSs as the preferred initial long-term controller therapy for asthma, but more effective initial controller therapy could be developed for COPD.

Abstract
AIMS The primary aim of the objective of the study was to determine the effects of long-term treatment with the recommended dose of inhaled fluticasone propionate spray usage on bone mineral status in children with asthma. METHODS This cross-sectional, case-control study was of 270 pre-pubertal children with asthma, who had used inhaled fluticasone propionate at a mean daily dose of 200 μg (range: 200-350 μg) for at least 5 years. The bone mineral density (BMD) of the lumbar spine was measured by dual-energy X-ray absorptiometry (DEXA). The results were compared to untreated controls (n=200), who were newly diagnosed children with asthma without any corticosteroid treatment. RESULTS The 270 study patients (175 males) were aged between 6 and 13 years. The average age (±SEM) was 9.2±0.6 years, and the mean (±SEM) steroid dosage used was 183.3±57.0 μg daily, with 236.5±17.2 g total steroid use during treatment. Between the study and the control groups, no significant difference was observed in BMD (p>0.05). CONCLUSION The findings suggest that long-term periodical treatment for 5 years with inhaled fluticasone propionate, 100 μg twice daily, in children with asthma revealed no negative effect on bone mineral density by using DEXA.

Abstract
Inhaled corticosteroids (ICS) are drugs of choice for persistent asthma. Less than 500 µg/d of fluticasone are believed to be safe. We found 92 cases of adrenal suppression in PubMed; among these cases there were 13 children who took 500 µg/d or less of fluticasone. Adrenal insufficiency was diagnosed in a 7-year-old boy on 460 µg ICS for 16 months, with a diagnosis of chronic persistent asthma. A random cortisol was nondetectable as was an early morning cortisol. ICS have greatly improved the day-to-day lives of children with chronic persistent asthma. Parents of children younger than 12 years, who use at least 400 µg of inhaled fluticasone (or bioequivalent), must be given oral and written instructions about warning symptoms of hypocortisolism. Major stress such as surgery, gastrointestinal, bronchopulmonary, or other systemic infections, and heat stress may mandate a written plan of action for use by hospital physicians.

Abstract
BACKGROUND The use of inhaled glucocorticoids for persistent asthma causes a temporary reduction in growth velocity in prepubertal children. The resulting decrease in attained height 1 to 4 years after the initiation of inhaled glucocorticoids is thought not to decrease attained adult height. METHODS We measured adult height in 943 of 1041 participants (90.6%) in the Childhood Asthma Management Program; adult height was determined at a mean (±SD) age of 24.9±2.7 years. Starting at the age of 5 to 13 years, the participants had been randomly assigned to receive 400 μg of budesonide, 16 mg of nedocromil, or placebo daily for 4 to 6 years. We calculated differences in adult height for each active treatment group, as compared with placebo, using multiple linear regression with adjustment for demographic characteristics, asthma features, and height at trial entry. RESULTS Mean adult height was 1.2 cm lower (95% confidence interval [CI], -1.9 to -0.5) in the budesonide group than in the placebo group (P=0.001) and was 0.2 cm lower (95% CI, -0.9 to 0.5) in the nedocromil group than in the placebo group (P=0.61). A larger daily dose of inhaled glucocorticoid in the first 2 years was associated with a lower adult height (-0.1 cm for each microgram per kilogram of body weight) (P=0.007). The reduction in adult height in the budesonide group as compared with the placebo group was similar to that seen after 2 years of treatment (-1.3 cm; 95% CI, -1.7 to -0.9). During the first 2 years, decreased growth velocity in the budesonide group occurred primarily in prepubertal participants. CONCLUSIONS The initial decrease in attained height associated with the use of inhaled glucocorticoids in prepubertal children persisted as a reduction in adult height, although the decrease was not progressive or cumulative.

Abstract
OBJECTIVE To determine the prevalence of hypothalamic-pituitary-adrenal (HPA) axis suppression in asthmatic children on inhaled corticosteroids (ICS). METHODS Clinical and demographic variables were recorded on preconstructed, standardized forms. HPA axis suppression was measured by morning serum cortisol levels and confirmed by low-dose adrenocorticotropic hormone stimulation testing. RESULTS In total, 214 children participated. Twenty children (9.3%, 95% CI 5.3% to 13.4%) had HPA axis suppression. Odds of HPA axis suppression increased with ICS dose (OR 1.005, 95% CI 1.003 to 1.009, P<0.001). All children with HPA axis suppression were on a medium or lower dose of ICS for their age (200 μg/day to 500 μg/day). HPA axis suppression was not predicted by drug type, dose duration, concomitant use of long-acting beta-agonist or nasal steroid, or clinical features. CONCLUSION Laboratory evidence of HPA axis suppression exists in children taking ICS for asthma. Children should be regularly screened for the presence of HPA axis suppression when treated with high-dose ICS (>500 μg/day). Consideration should be given to screening children on medium-dose ICS.

Abstract
BACKGROUND Inhaled corticosteroids (ICS) and intranasal steroids (INS) are frequently co-administered in children with asthma and rhinitis. In contrast to monotherapy with ICS or INS, little is known about the safety of concurrent use of topical steroids on hypothalamic-pituitary-adrenal (HPA) axis function in prepubertal children. OBJECTIVE Comparison of morning salivary cortisol levels in prepubertal children using maintenance treatment with ICS with and without concurrent use of INS to steroid naïve control groups (healthy children, and children with constipation who are under pediatric care). METHODS Cross-sectional observational study in prepubertal children (6-12 years) using ICS alone (n = 41) or in combination with INS (n = 22), compared to different control groups with no steroid treatment (18 healthy children, and 28 children with constipation). Morning salivary cortisol levels were determined from saliva samples collected at home. RESULTS The morning salivary cortisol levels of the healthy children (8.7 nmol/L; 95% CI 5.9-18.8), and the children with constipation (8.9 nmol/L; 8.0-11.3) were comparable. The salivary cortisol levels of prepubertal children using ICS (median 4.7 nmol/L; 95% CI 4.6-6.9) or a combination of ICS and INS (5.1 nmol/L; 4.2-7.6) were comparable, but significantly reduced compared to both control groups. There was no correlation between salivary cortisol level and age, duration of disease, or cumulative daily dose of topical steroids. CONCLUSION Salivary cortisol levels in prepubertal children using ICS, with or without concurrent use of INS, were comparable. However, salivary cortisol levels were significantly reduced compared to steroid naïve controls, irrespective of the cumulative daily dose of topical steroids. Pediatr.

Abstract
PURPOSE OF REVIEW The purpose of this review is to compare and contrast the newer inhaled corticosteroid (ICS) ciclesonide with older ICSs in terms of pharmacodynamic and pharmacokinetic properties and how these affect comparative efficacy. In addition, clinical dosing strategies for ICSs including as-needed use will be explored. RECENT FINDINGS Ciclesonide has demonstrated similar efficacy to that of fluticasone propionate and mometasone furoate in equipotent doses with a potentially improved therapeutic index. Once-daily administration of ICSs is generally not as effective as twice-daily. Continuous administration of ICSs does not change the natural history of asthma in either children or adults. Long-term administration of medium dose ICSs does not increase the risk of cataracts or osteopenia in children and young adults. Studies of as-needed ICSs in mild persistent asthma in adults and children have demonstrated mixed results, with some showing equal efficacy to continuous therapy and others showing superiority of continuous therapy. SUMMARY Ciclesonide provides a newer ICS with favorable pharmacokinetics that may improve the therapeutic index, but assessment of its systemic effects such as growth await further studies. Continuous administration of ICSs in low to medium dose over many years is well tolerated. The use of as-needed ICSs in patients with mild persistent asthma is promising as a potential step-down therapy but awaits further studies.

Abstract
Inhaled corticosteroids (ICSs) are the most effective anti-inflammatory agents available for the treatment of asthma and represent the mainstay of therapy for most patients with the disease. Although these medications are considered safe at low-to-moderate doses, safety concerns with prolonged use of high ICS doses remain; among these concerns is the risk of adrenal suppression (AS). AS is a condition characterized by the inability to produce adequate amounts of the glucocorticoid, cortisol, which is critical during periods of physiological stress. It is a proven, yet under-recognized, complication of most forms of glucocorticoid therapy that can persist for up to 1 year after cessation of corticosteroid treatment. If left unnoticed, AS can lead to significant morbidity and even mortality. More than 60 recent cases of AS have been described in the literature and almost all cases have involved children being treated with ≥500 μg/day of fluticasone. The risk for AS can be minimized through increased awareness and early recognition of at-risk patients, regular patient follow-up to ensure that the lowest effective ICS doses are being utilized to control asthma symptoms, and by choosing an ICS medication with minimal adrenal effects. Screening for AS should be considered in any child with symptoms of AS, children using high ICS doses, or those with a history of prolonged oral corticosteroid use. Cases of AS should be managed in consultation with a pediatric endocrinologist whenever possible. In patients with proven AS, stress steroid dosing during times of illness or surgery is needed to simulate the protective endogenous elevations in cortisol levels that occur with physiological stress. This article provides an overview of current literature on AS as well as practical recommendations for the prevention, screening and management of this serious complication of ICS therapy.

Abstract
Inhaled corticosteroids (ICS) are recommended by The National Asthma Education and Prevention Program's Expert Panel Report 3 for all levels of persistent asthma in the pediatric population. The recommended ICS doses are based on assessment of severity and control of asthma. The pharmacodynamics and pharmacokinetics of the current ICSs are reviewed. While comparable efficacy can be achieved with equipotent dosing, some of the newer ICSs, fluticasone propionate, mometasone furoate, and ciclesonide, have pharmacokinetic profiles that produce less risk of systemic effects. However, at high doses systemic activity increases with all ICSs. The clinicians need to weigh the benefits and risks of these different products and dosing schemes in their patients for optimal use.

Abstract
OBJECTIVE Although systemic, topical, and periocular corticosteroid administration have long been associated with ocular side effects, there has been little evidence to suggest that long-term inhaled corticosteroids can cause ocular side effects. The aim of this study was to evaluate the effects of long term treatment inhaled fluticasone propionate spray usage the recommended dose on some ocular functions in pediatric patients with asthma. METHODS The study group consisted of 266 prepubertal children with asthma who had used inhaled fluticasone propionate spray at 3-6 years intermittently. One hundred and sixty children who were newly diagnosed with asthma without any treatment made up the control group. Schirmer test results, central corneal thickness, visual acuity, intraocular pressure, cataract formation, keratometry and tear break-up time compared between study and control groups. RESULTS The ages of the 266 study patients (150 male) were between 7 and 11 years. The average age (±SEM) was 8.2±1.7 years, and the mean (±SEM) a daily dose of 323 μg (range 250-450 μg) inhaled fluticasone propionate spray, with 865.2±215 g total steroid use during treatment. Eye functions including cataract formation, corneal ectasia, ocular hypertension or glaucoma, and dry eye were not observed in any of the patients in the study group and were not correlated with total steroid dosage (t=0.150, p=0.384). CONCLUSION Our findings suggest that long-term intermittent treatment for 3-6 years with inhaled fluticasone propionate spray, as much as average 320 μg daily, in children with asthma seems to be safe for some eye functions.

Abstract
INTRODUCTION Asthma is the most frequent children's disease, with a tendency of further growth. Bearing in mind controversial data on obesity of asthmatic children and a possible effect of inhaled corticosteroids (ICS) on children's growth, the aim of our study was to determine the body mass index (BMI) in asthmatic children at the beginning of the therapy and to study the effect of the continuous application of ICS on growth and BMI during the period of 1 year. MATERIAL AND METHODS The study included 100 children aged 7 to 18 diagnosed to have partly controlled and uncontrolled allergic asthma, who were continuously given ICS as a prevention against asthma attacks at Pediatric Clinic of the Clinical Center in Kragujevac for the period of 1 year. Children with BMI < p10 by their age and gender were considered to be underweight, children with p10-84 as of normal weight, children with p85-97 as overweight and children with BMI > p97 as obese. RESULTS The highest percentage of children with asthma was within normal parameters (70%), 10% of the children were underweight (boys: n = 8/60, 13.3% vs. girls: n = 2/40, 5%), and 18% were overweight/obese. Monovariable analysis of variant with repeated measurements have shown a statistically significant difference in the height of children in all age groups after a year of continuous therapy of ICS (p = 0.000), except in girls aged 15-18, who did not show any significant difference in body height after the therapy (p > 0.05). CONCLUSION Asthmatic children with partly controlled and uncontrolled asthma have mostly normal BMI and ICS can be safely administered in asthmatic children.

Abstract
AIM Reduced basal cortisol is reported in allergic disease. We investigated if basal salivary cortisol levels were reduced in children with asthma or allergic rhinitis, controlling for inhaled corticosteroids (ICS) use. METHODS Morning and evening saliva of asthmatic children aged 7-12 years (n = 50) and that of controls (n = 52) were sampled. A total of 19 asthmatics and four controls had allergic rhinitis. Healthy children were controls without rhinitis. Of all, 14 asthmatic children used low, and 12 used moderate or high doses of ICS. Cortisol was analysed by radioimmunoassay. RESULTS Morning salivary cortisol median (95% CI) was lower in asthmatics (8.7 (7.1, 9.7)) compared with that in controls (10.4 (9.6, 11.8); p = 0.006), which was similar for evening cortisol levels. Regression analyses demonstrated that asthmatics using moderate or high doses of ICS had reduced morning salivary cortisol adjusted (for age and gender) odds ratio (aOR) (95% CI) (0.54 (0.37, 0.80); p = 0.002) and reduced evening cortisol aOR (0.09 (0.01, 0.6); p = 0.02) compared with that in healthy children. Asthmatics with rhinitis on no or low doses of ICS had reduced morning cortisol aOR (0.73 (0.56, 0.96); p = 0.02) compared with that in healthy children. CONCLUSION Asthmatic children on moderate or high doses of inhaled corticosteroids had reduced salivary cortisol, but co-morbidity of asthma and rhinitis was also associated with reduced cortisol levels.

Abstract
In a double-blind, randomized study, 136 children, 5-10-y-old, with newly detected persistent asthma received budesonide (BUD) 400 microg twice daily for 1 mo and thereafter 200 microg twice daily for 5 mo. Thereafter, 50 children were treated with BUD 100 microg twice daily, whereas 44 children used BUD as needed for 1 y; an additional 42 children received disodium cromoglycate (DSCG). Asthma exacerbations were treated with BUD for 2 wk in a dose of 400 microg twice daily in all groups. In this secondary analysis, bone mineral density (BMD) of the lumbar vertebrae was measured before and after the 18-mo treatment. Compared with DSCG, regular BUD treatment resulted in a significantly smaller increase in BMD (0.023 versus 0.034 g/cm; p = 0.023) and height (7.75 versus 8.80 cm; p = 0.001). Periodic treatment did not affect BMD. No intergroup differences were observed when BMD data were adjusted for changes in height. Daily BUD treatment in prepubertal children may slow down the increment in BMD and standing height. This was not observed in children receiving BUD periodically after the initial regular BUD treatment. The correlation between height and BMD suggests that following children's height might afford an estimation of inhaled corticosteroid effects on bone.

Abstract
The role of inhaled corticosteroids (ICS) as rescue medication for asthma exacerbations in children is controversial. ICS have the important potential advantage of direct delivery to the airways, which substantially reduces the risk of the adverse systemic effects that may be associated with oral corticosteroids. Oral corticosteroids are still preferred for severe attacks. Five randomized, controlled studies performed at home and six performed in the emergency department indicated that ICS are at least as effective as the oral route. Our pediatric out-patient asthma clinic has been using ICS for asthma exacerbations for more than 25 years. The key elements to success are the administration of repetitive doses at least four-times higher than the maintenance dose and parental adherence to the treatment plan. This article reviews the findings in the literature favoring this approach and describes our methodology in detail.

Abstract
Current national and international asthma guidelines recommend treatment of children with asthma towards achieving and maintaining asthma control. These guidelines provide more stringent recommendations to increase therapy for patients with uncontrolled asthma in order to reduce asthma-related morbidity and mortality. Newer combination agents such as budesonide and formoterol have been shown to be safe and effective in treatment of asthma in children. Use of long-term controller agents like this in combination with improved compliance and treatment of co-morbid conditions have been successful in this endeavor. This review discusses control of pediatric asthma with focus on the use of budesonide in combination with formoterol.

Abstract
Few studies on the concomitant effects of beclomethasone dipropionate and asthma-related factors on the growth of prepubertal asthmatic children have been published to date. In this prospective long-term 'real-life' cohort study we recruited 82 prepubertal steroid-naïve asthmatic patients aged 3 + years, excluding those with birth weight lower than 2500 g, malnutrition, and other concurrent chronic diseases. Height/age and weight/age Z scores were calculated every three months. Random effects multivariate longitudinal data analysis was used to adjust height/age and weight/age Z scores with independent variables. Among the studied patients, 63.4% were male, aged 4.7 + or - 1.5 years, 68.3% suffered from severe persistent asthma and had normal values for height/age and weight/age Z scores at enrolment. They were followed for 5.2 years (range 2.3-6.1) and used a mean daily beclomethasone dipropionate dose of 351.8 mcg (range 137.3-1140.0). Height/age and weight/age Z scores were not affected by either duration of treatment or doses of beclomethasone dipropionate up to 500 mcg, 750 mcg and higher than 750 mcg (p-values > 0.17). The multivariate analysis final model showed that severe persistent asthma was associated to lower height for age Z score (p = 0.04), whereas hospitalizations because of acute asthma (before and during follow-up) were associated (p = 0.02) to lower weight for age Z score. Growth parameters were not affected by the use of beclomethasone dipropionate.

Abstract
In adults, asthma treatment with high doses of inhaled corticosteroids has resulted in dermal thinning. The aim of this study was to investigate the skin thickness in children with asthma during budesonide treatment. In a double-blind study, 113 children, 5-10 y old, with persistent asthma received budesonide 400 microg twice daily for 1 mo and thereafter 200 microg twice daily for 5 mo. Thereafter, 56 children received 100 microg twice daily for 1 y, whereas 57 other children used budesonide periodically for exacerbations. An additional 54 children were treated with disodium cromoglycate (DSCG) for 18 mo. Skin thickness was measured on each forearm before and after treatment for 6, 12, and 18 mo using a 20-MHz high-resolution ultrasonic device. The initial 6-mo budesonide treatment resulted in a greater reduction in mean skin thickness in the forearms compared with DSCG (right: -35.9 versus -5.9 microm; p = 0.004; left: -30.6 versus -7.3 microm; p = 0.03). At month 18, the inter-group differences were no longer significant. Budesonide inhalations in daily doses of 400-800 microg in prepubertal children with newly detected asthma may cause minor dermal thinning. The changes were reversible during low dose or periodic treatment with budesonide.

Abstract
BACKGROUND International guidelines recommend regular treatment with inhaled glucocorticoids for children with frequent wheezing; however, prn inhaled bronchodilator alone or in combination with glucocorticoid is also often used in practice. We aimed to evaluate whether regular nebulized glucocorticoid plus a prn bronchodilator or a prn nebulized bronchodilator/glucocorticoid combination is more effective than prn bronchodilator alone in preschool children with frequent wheeze. METHODS Double-blind, double-dummy, randomized, parallel-group trial. After a 2-week run-in period, 276 symptomatic children with frequent wheeze, aged 1-4 years, were randomly assigned to three groups for a 3-month nebulized treatment: (1) 400 microg beclomethasone bid plus 2500 microg salbutamol prn; (2) placebo bid plus 800 microg beclomethasone/1600 microg salbutamol combination prn; (3) placebo bid plus 2500 microg salbutamol prn. The percentage of symptom-free days was the primary outcome measure. Secondary outcomes included symptom scores, use of relief medication and exacerbation frequency. RESULTS As compared with prn salbutamol (61.0 +/- 24.83 [SD]), the percentage of symptom-free days was higher with regular beclomethasone (69.6%, SD 20.89; P = 0.034) but not with prn combination (64.9%, SD 24.74). Results were no different in children with or without risk factors for developing persistent asthma. The effect of prn combination was no different from that of regular beclomethasone on the primary and on several important secondary outcomes. CONCLUSIONS Regular inhaled glucocorticoid is the most effective treatment for frequent wheezing in preschool children. However, prn bronchodilator/glucocorticoid combination might be an alternative option, but it requires further study.

Abstract
The global burden of childhood asthma is significant. Health care systems are faced with increasing financial costs, while children with asthma and their caretakers are faced with poorer physical health, emotional health, and quality of life. Despite the availability of effective treatment, the quality use of asthma medicines in children remains suboptimal. An investigation was conducted to explore issues related to children's asthma medicine usage from the perspective of the health care professional. Although current literature has elicited the views of caretakers and children, the health care professional viewpoint has been relatively unexplored. Semi-structured qualitative interviews were conducted with a convenience sample of 21 Australian asthma educators. Interviews were audiotaped and transcribed, and transcripts were thematically analyzed with the assistance of NVivo 7. Emergent themes associated with health care professionals, parents, medicines, children, and educational resources were found. Major issues included a lack of information provided to parents, poor parental understanding of medicines, the high cost of medicines and devices, child self-image, the need for more child responsibility over asthma management, and the lack of standardization, access to, and funding for educational resources on childhood asthma. There are multitudes of key issues that may affect asthma medicines usage in children. This research will help inform the development of educational tools on the use of medicines in childhood asthma that can be evaluated for their effectiveness in getting key messages to target audiences such as children, caretakers, and teachers.

Abstract
Inhaled corticosteroid (ICS) therapy in combination with long-acting beta-adrenergic agonists represents the most important treatment for chronic airways diseases such as asthma and chronic obstructive pulmonary disease (COPD). ICS therapy forms the basis for treatment of asthma of all severities, improving asthma control, lung function and preventing exacerbations of disease. Use of ICS has also been established in the treatment of COPD, particularly symptomatic patients, who experience useful gains in quality of life, likely from an improvement in symptoms such as breathlessness and in reduction in exacerbations, and an attenuation of the yearly rate of deterioration in lung function. The addition of long-acting beta-agonist (LABA) therapy with ICS increases the efficacy of ICS effects in moderate-to-severe asthma. Thus, a 800 mug daily dose of the ICS budesonide reduced severe exacerbation rates by 49% compared to a low dose of 200 mug daily, and addition of the LABA formoterol to budesonide (800 mug) led to a 63% reduction. In COPD, the effects of ICS are less prominent but there are beneficial effects on the decline in FEV(1) and the rate of exacerbations. A reduction in the rate of decline in FEV(1) of 16 ml/year with a 25% reduction in exacerbation rate has been reported with the salmeterol and fluticasone combination. A non-significant 17.5% reduction in all-cause mortality rate with ICS and LABA is reported. Chronic inflammation is a feature of both asthma and COPD, although there are site and characteristic differences. ICS targets this inflammation although this effect of ICS is less effective in patients with severe asthma and with COPD; however, addition of LABA may potentiate the anti-inflammatory effects of ICS. An important consideration is the presence of corticosteroid insensitivity in these patients. Currently available ICS have variably potent binding activities to specific glucocorticoid receptors, leading to inhibition of gene expression by either binding to DNA and inducing anti-inflammatory genes or by repressing the induction of pro-inflammatory mediators. Local side effects of ICS include oral candidiasis, hoarseness and dysphonia, while systemic side effects, such as easy bruising and reduction in growth velocity or bone mineral densitometry, are usually restricted to doses above maximally recommended doses. Use of LABA alone in patients with asthma increases the risk of asthma-related events including deaths, but this is less observed with the combination of ICS and LABA. Therefore, use of LABA alone is not recommended for asthma therapy. Future progress in ICS development will be characterised by the introduction of ICS with greater efficacy with a limited side-effect profile, and by longer-acting ICS that can be used in combination with once-daily LABAs. Other agents that could improve the efficacy of corticosteroids or reverse corticosteroid insensitivity may be added to ICS. ICS in combination with LABAs will continue to remain the main focus of treatment of airways diseases.

Abstract
The stress system co-ordinates the adaptive responses of the organism to stressors of any kind. Inappropriate responsiveness may account for increased susceptibility to a variety of disorders, including asthma. Accumulated evidence from animal models suggests that exogenously applied stress enhances airway reactivity and increases allergen-induced airway inflammation. This is in agreement with the clinical observation that stressful life events increase the risk of a new asthma attack. Activation of the hypothalamic-pituitary-adrenal (HPA) axis by specific cytokines increases the release of cortisol, which in turn feeds back and suppresses the immune reaction. Data from animal models suggest that inability to increase glucocorticoid production in response to stress is associated with increased airway inflammation with mechanical dysfunction of the lungs. Recently, a growing body of evidence shows that asthmatic subjects who are not treated with inhaled corticosteroids (ICS) are likely to have an attenuated activity and/or responsiveness of their HPA axis. In line with this concept, most asthmatic children demonstrate improved HPA axis responsiveness on conventional doses of ICS, as their airway inflammation subsides. Few patients may experience further deterioration of adrenal function, a phenomenon which may be genetically determined.

Abstract
OBJECTIVE The role of inhaled corticosteroids in the treatment of acute asthma exacerbations in children is controversial. This study compared the effect of inhaled budesonide and inhaled fluticasone in controlling acute asthma exacerbations in young children at home. METHODS In a quasi-randomized crossover design, children aged 5 months to 5 years with severe recurrent asthma episodes were treated either with inhaled budesonide 200 mcg or inhaled fluticasone 125 mcg delivered with a similar spacer. At the onset of asthma exacerbations, 2 puffs of inhaled terbutaline followed by inhaled budesonide or fluticasone was administered using one of the following treatment protocols: 1 4-day protocol for a relatively mild exacerbation; 2 8-day protocol for exacerbations that were more severe or uncontrolled by the 4-day protocol; and 3 8-day protocol + azithromycin for exacerbations uncontrolled by the 8-day protocol or possibly associated with infection with atypical agents. Children were followed for 2 months after each exacerbation. Good response was defined as the absence of asthma symptoms for at least 2 weeks from completion of treatment. RESULTS One hundred children were recruited: 36 were treated with budesonide, 21 with fluticasone, and 44 with both on different occasions. The groups were similar for preliminary data. Good response was noted in 87% of the budesonide group, 85% of the fluticasone group, and 86% of the budesonide/fluticasone group. By protocol, rates of good response were 84%, 83%, and 94% for the 4-day, 8-day, and 8-day+azithromycin treatment protocols, respectively; corresponding symptom-free periods after treatment were 4.0, 4.9, and 4.3 weeks. None of the children received oral corticosteroids. CONCLUSION Acute asthma exacerbations in young children can be effectively controlled at home with the use of high repetitive doses of inhaled budesonide or inhaled fluticasone, initially together with beta(2)-agonists, given at the beginning of the attack, for a period of 4-8 days.

Abstract
Drugs for asthma and other chronic obstructive diseases of the lungs should be preferably delivered by the inhalation route to match therapeutic effects with low systemic exposure. Inhaled drugs are delivered to the lungs via different devices, mainly metered dose inhalers and dry powder inhalers, each characterized by specific inhaler technique and instructions for use. The patient-device interaction is part of the prescribed therapy and can have a relevant impact on adherence and clinical outcomes. The most suitable device should be considered for each patient to assure the correct drug intake and adherence to the prescribed therapy. The development of new drugs/devices in the past decades improved the compliance with inhaler and possibly drug delivery to the bronchi. The present review focuses on the recently developed beclomethasone/formoterol extrafine fixed combination and technical aspects of drug delivery to the lungs in patient's perspective.

Abstract
Reduced responsiveness of the hypothalamic-pituitary-adrenal (HPA) axis in patients with various chronic allergic inflammatory disorders and a blunted HPA axis response of poorly controlled asthmatics before long-term treatment with inhaled corticosteroids (ICS) have been reported. It seems that pro- and anti-inflammatory cytokines might be involved in the attenuation of cortisol and adrenocorticotropic hormone (ACTH) responses to stress in these patients. Although long-term ICS treatment might produce mild adrenal suppression in some asthmatic children, improvement of adrenal function has been detected in the majority of cases. We postulate that the anti-inflammatory effects of ICS result both in asthma remission and HPA axis improvement. Adrenal suppression of some asthmatic patients on maintenance ICS seems to be a separate phenomenon, possibly constitutionally or genetically determined.

Abstract
BACKGROUND Topical administration of Corticosteroids (CS) can reduce the total dose of CS required to treat the patient and minimize side effects. Topical CS is extremely effective and has an excellent safety profile. Nonetheless, care must be taken when multiple sites such as lungs, nose and skin are being treated. CS mechanisms of action on the inflammatory process are complex. The aim of this study is to review such mechanisms and the adverse events secondary to it. METHODS Review English database (Embase, PubMed, Scielo) searching words: CS, adverse events, inhaled CS, intranasal CS, and children. RESULTS There is a classic mechanism involving a genomic effect of CS and a non-genomic effect, independently of gene transcription process. This mechanism acts by reducing mucosal blood flow in the asthmatic airways. Second-generation topical CS is the treatment of choice in allergic diseases control because of their good anti-inflammatory activity, poor absorption and first-pass hepatic metabolism. When comparing different CS, it is important to compare therapeutically equivalent doses. Although topical CS reduces systemic side effects, local and even systemic side effects can occur. Many factors affect the amount of drug that reaches the lung, including inhaler technique and inhaler type, fine particle dose and particle distribution. CONCLUSION Most patients with allergic diseases respond to CS treatment, but there is a small subset of them whose response is unsatisfactory even with high doses of CS. They are classified as corticosteroid-resistant asthmatics. Pro-inflammatory cytokines appear to up regulate the expression of GRb that has been associated with CS resistance.

Abstract
Specific concerns from 706 parents regarding their children's (M age = 8.0, SD = 3.9) use of daily asthma medications were systematically identified and organized. 270 (38.2%) of 706 parents expressed a total of 470 concerns (M = 1.74, SD = 0.93; Range 1-5), including concerns about side effects (48.9%; e.g., growth retardation); aspects of the regimen (29.3%; e.g., medication amount); and "steroid" use (10.4%). Independent predictors of parental concern included use of inhaled corticosteroids (OR = 1.60, 95% CI 1.07-2.40), nasal corticosteroids (OR = 1.70, 95% CI 1.21-2.38), and alternative therapies (OR = 1.84, 95% CI 1.32-2.56). Providers should be prepared to address a wide range of medication concerns, especially those related to side effects.

Abstract
OBJECTIVE To analyse trends in asthma medications used by school-entry children whose parents report they have asthma. DESIGN AND SETTING Annual cross-sectional study of all school-entry children (about 4400 each year) in the Australian Capital Territory in 2000-2005, by means of a questionnaire for parents on child health status and medication use; and a cross-sectional study of asthma prescriptions for children aged 5 years obtained from the Medicare Australia database for 2002-2005. PARTICIPANTS All school-entry children in the ACT with parent-reported asthma (numbers in the years 2000-2005 ranged between 435 and 589). MAIN OUTCOME MEASURES Changes in the use of different medications; changes in delivery devices for asthma; changes in the potency of inhaled fluticasone. RESULTS Response rates to kindergarten health screening were in the range 85%-89% for 2000-2005. Parent-reported asthma prevalence ranged from 11% to 15%. Each year, around 35% of children with asthma (age range, 4-6 years) used inhaled corticosteroids. An increase in the use of fluticasone (from 11% to 33% of children with asthma) was offset by decreases in beclomethasone use (from 14% to 3%) and budesonide (from 14% to 4%). Use of cromoglycate and nedocromil fell from 46% to 16%. Nebuliser use decreased (from 45% to 20%), while the use of spacer devices increased (from 70% to 83%). Use of combined salmeterol/fluticasone increased from 8% (in 2002) to 20% (in 2005) of children with parent-reported asthma. These trends were mirrored in Medicare Australia data for 5-year-old children in the ACT. CONCLUSIONS There was marked volatility in the types of asthma medication used over the 6 years. Reciprocal trends leading to increased use of spacers and decreased use of nebulisers are in accord with national guidelines for better asthma management. The increasing use of products containing a combination of salmeterol and fluticasone requires ongoing monitoring.

Abstract
Inflammatory processes of the upper and lower airway commonly co-exist. Patients with upper respiratory illnesses such as allergic rhinitis and acute and chronic rhinosinusitis often present to both otolaryngologists and primary care physicians for treatment of their symptoms of nasal and sinus disease. These patients often have concurrent lower respiratory illnesses such as asthma that may be contributing to their overall symptoms and quality of life. Unfortunately, asthma frequently remains undiagnosed in this population. It was the objective of this paper to examine the relationship between upper respiratory illnesses such as rhinitis and rhinosinusitis and lower respiratory illnesses such as asthma, and to provide a framework for primary care and specialty physicians to approach these illnesses as a spectrum of inflammatory disease. The present manuscript was developed by a multidisciplinary workgroup sponsored by the American Academy of Otolaryngic Allergy. Health care providers in various specialties contributed to the manuscript through preparation of written materials and through participation in a panel discussion held in August 2006. Each author was tasked with reviewing a specific content area and preparing a written summary for inclusion in this final document. Respiratory inflammation commonly affects both the upper and lower respiratory tracts, often concurrently. Physicians who are treating patients with symptoms of allergic rhinitis and rhinosinusitis must be vigilant to the presence of asthma among these patients. Appropriate diagnostic methods should be used to identify individuals with concurrent respiratory illnesses, and comprehensive treatment should be instituted to reduce symptoms and improve quality of life.
