Abstract
INTRODUCTION Inhaled corticosteroids (ICS) are known to increase the risk of systemic and local adverse effects, especially with high doses and long-term use. Hence, considerable resources are invested to improve pharmacokinetic/pharmacodynamic (PK/PD) properties of ICS, effective delivery systems and novel combination therapies to enhance the risk-to-benefit ratio of ICS. AREAS COVERED There is an unmet need for new solutions to achieve optimal clinical outcomes with minimal dose of ICS. This paper gives an overview of novel treatment strategies regarding the safety of ICS therapy on the basis of the three most recent molecules introduced to our everyday clinical practice - ciclesonide, mometasone furoate, and fluticasone furoate. Advances in aerosol devices and new areas of inhalation therapy are also discussed. EXPERT OPINION Current progress in improving the risk-to-benefit ratio of ICS through dose and delivery probably established pathways for further developments. This applies both to the improvement of the PK/PD properties of ICS molecules but also includes technical aspects that lead to simplified applicability of the device with simultaneous optimal drug deposition in the lungs. Indubitably, the future of medicine lies not only in the development of new molecules but also in technology and digital revolution.

Abstract
Background: Parental concerns about the adverse effects of asthma medications can lead to nonadherence and uncontrolled asthma in children. Ciclesonide (CIC) is a prodrug, with low oropharyngeal deposition and bioavailability that may minimize the risk of local and systemic adverse effects. CIC is U.S. Food and Drug Administration approved for asthma in children ages ≥ 12 years. Objective: To summarize safety results from the 13 phase II or III randomized controlled trials conducted in children with asthma during CIC clinical development. Methods: Four 12- to 24-week trials compared the safety of once-daily CIC 40, 80, or 160 µg/day with placebo; four 12-week trials compared the safety of CIC 80 or 160 µg/day with either fluticasone or budesonide; one 12-month trial compared the long-term safety of CIC 40, 80, or 160 µg/day with fluticasone; one 12-month trial compared growth velocity of CIC 40 or 160 µg/day with placebo; and three cross-over trials compared short-term growth velocity and hypothalamic-pituitary-adrenal (HPA) axis effects of CIC 40, 80, or 160 µg/day with placebo or fluticasone. Results: In all, 4399 children were treated with CIC. The incidence of treatment-emergent adverse events (AE) was similar among the CIC doses and between CIC and placebo in short-term studies and between CIC and fluticasone in the long-term safety study. No CIC-related serious AEs were reported in any study. The incidence of treatment-related oral candidiasis was low and similar between CIC (≤0.5%) and placebo (≤0.7%) or active controls (≤0.5%) in the short-term studies. There was no clinically relevant HPA axis suppression or reduction in growth velocity associated with CIC. Conclusion: Data from 13 studies demonstrate that CIC is associated with low rates of oropharyngeal AEs, with no indication of clinically relevant systemic effects in children with asthma. The favorable safety profile and demonstrated improvements in asthma control make CIC an ideal inhaled corticosteroid for the treatment of asthma in children.

Abstract
OBJECTIVES Systemic activity of inhaled corticosteroids (ICS) may be assessed via urinary cortisol measurement. Overnight urinary free cortisol corrected for creatinine (OUFCC) has been extensively reported in adult studies. However, a paediatric mass spectrometric (MS) reference range for OUFCC is not established. MS methods for OUFCC avoid cross-reactivity with other steroid hormones and are thus preferable to immunoassays. The aim of the present study was to define an MS OUFCC normative range in children. METHODS This was a cross-sectional study of healthy pre-pubertal children from 5 to 11 years. Children collected urine from 10 pm or bedtime, whichever was earlier, until 8 am. Urinary free cortisol was measured via a liquid chromatography tandem mass spectrometry (LC-MS/MS) assay (Acquity UPLC with Xevo TQ-S Mass Spectrometer [Waters]) with in-house reagents. Urinary creatinine was measured using a commercial assay (Roche). RESULTS Complete urine collections were obtained from 72 males and 70 females, mean age (SD) 8.6 (1.9) (range 5.0-11.8) years. The OUFCC 95% prediction interval was 1.7-19.8 nmol/mmol. Geometric mean OUFCC was 5.7; range 1.1-24.8 nmol/mmol. CONCLUSIONS The obtained normative LC-MS/MS OUFCC reference data facilitate the use of mass spectrometry OUFCC assays in assessment of systemic activity of endogenous and exogenous corticosteroids in children.

Abstract
BACKGROUND For more than a decade, urinary free cortisol corrected for creatinine (OUFCC) has been used to assess the systemic bioactivity of inhaled corticosteroids in children with asthma. Paediatric normative ranges, however, have not been established. The aim of the present study was to define a preliminary range for OUFCC in Tanner stage 1 children. METHODS A post hoc analysis was performed of 26 Tanner stage one children (aged 5-11 years) with mild asthma only requiring prn (pro re nata) treatment with short-acting β2-agonists, who participated in a 3-way cross-over knemometry study. The study comprised a run-in, two washout periods and three treatment periods (2 weeks each). Urine was collected at the end of each period. A normative range was derived using the 95% prediction interval for the geometric mean OUFCC, calculated from run-in and washout periods. RESULTS Twenty-six children contributed 41 OUFCC values. The geometric mean OUFCC was 9.0 nmol/mmol (95% PI: 3.6, 22.7 nmol/mmol). CONCLUSIONS The OUFCC preliminary normative range was 3.6 to 22.7 nmol/mmol in Tanner stage one children. A larger study in healthy children is warranted to confirm these findings and to assess potential differences in OUFCC across developmental stages and age groups, and by gender and race.

Abstract
As new therapies for pediatric asthma are approved by the Food and Drug Administration, clinicians should be aware of their benefits and limitations. Accompanying these therapies are potential obstacles, including the delivery of inhaled therapies and age-specific issues regarding implementation and adherence. New insights are being added to well-established controller medications, including inhaled corticosteroids and long-acting β-agonists, while new medications previously approved in adults, including tiotropium and biologics, are now being evaluated for use in children. These drugs can be useful additive therapies to treat patients who are currently not responding to guidelines-based therapy.

Abstract
INTRODUCTION Many trials have been published comparing inhaled corticosteroid (ICS) treatments in asthma. However, mixed results necessitate the summarization of available evidence to aid in decision-making. Areas covered: This systematic review evaluated randomized controlled trials (RCTs) that compared the efficacy and safety of inhaled fluticasone propionate (FP) with other ICS including beclomethasone dipropionate (BDP), budesonide (BUD) and ciclesonide (CIC). PubMed was searched and 54 RCTs that fit pre-determined criteria were included. Endpoints evaluated included lung function, asthma symptom control, exacerbation frequency, reliever use, quality of life and steroid-related side effects. Expert commentary: Across all studies, FP was associated with either more favorable or at least similar efficacy and safety, in comparison with BDP or BUD. This observation may be related to FP's higher relative potency and almost negligible oral bioavailability. FP was comparable to CIC for efficacy. However, CIC appeared to have a smaller impact on cortisol levels than FP, which is likely due to CIC's incomplete conversion to active metabolite (des-CIC) and the lower potency of des-CIC compared with FP. Although there were no significant differences in evaluated outcomes after treatment with different ICS in the majority of studies, some observed differences could be explained by their respective pharmacodynamic and pharmacokinetic properties.

Abstract
BACKGROUND Fluticasone propionate/formoterol (FP/FORM) is a pressurized metered-dose inhaler (pMDI; Flutiform®) approved for use in adolescents and adults and under development for pediatric use. OBJECTIVE To compare short-term growth in asthmatic children treated with FP/FORM, FP pMDI with valved holding chamber, and beclomethasone dipropionate (BDP) in a breath-actuated device. METHODS Children with persistent asthma (n = 48; 5 to <12 years) participated in an assessor-blinded, randomized, three-way crossover trial with run in, wash out, and active treatment periods, each of 2 weeks duration. Interventions were FP/FORM 100/10 μg b.i.d. with an AeroChamber Plus® Flow-Vu® Spacer, FP pMDI (Flixotide®) 100 μg b.i.d. with a Volumatic® spacer, and extra-fine BDP breath-actuated inhaler (Aerobec®/QVAR® Autohaler®) 100 μg b.i.d. Lower leg growth rate (LLGR) was measured by knemometry. RESULTS The least square (LS) mean difference in LLGR between FP/FORM and FP (per protocol population) was -0.006 mm/week (95% CI: -0.095 to 0.084; p < 0.001 for noninferiority [noninferiority margin -0.200 mm/week]). Both treatments elicited no change from baseline off-treatment growth rate. The LS mean treatment difference of FP/FORM versus BDP was 0.116 mm/week (95% CI: -0.004 to 0.235; p = 0.057) and of FP versus BDP 0.163 mm/week (95% CI: 0.078-0.249; p < 0.001). Results in the full analysis population were: FP/FORM versus FP -0.012 mm/week (95% CI: -0.080-0.056; p < 0.001); FP/FORM versus BDP 0.143 mm/week (95% CI: 0.064-0.222; p < 0.001); FP versus BDP 0.163 mm/week (95% CI: 0.093-0.233; p < 0.001). CONCLUSIONS FP/FORM pMDI with AeroChamber and FP pMDI with Volumatic spacer did not affect lower leg growth, measured by knemometry, in asthmatic children. Conversely, extra-fine BDP from a breath-actuated inhaler resulted in short-term growth suppression.

Knemometry is more sensitive to systemic effects of inhaled corticosteroids in children with asthma than 24-hour urine cortisol excretion. J Allergy Clin Immunol 2016; 140:431-436.

Abstract
BACKGROUND Pharmacodynamic assessment of the systemic effect of inhaled corticosteroids (ICSs) is often done by measuring 24-hour urine free cortisol (UFC) excretion. Knemometry assessing short-term lower-leg growth rate (LLGR) is a more rarely used alternative. OBJECTIVE The primary aim of this study was to compare the sensitivity of LLGR and 24-hour UFC excretion for evaluating systemic exposure to ICSs in prepubertal children with asthma. The secondary aim was to evaluate factors influencing the precision of LLGR calculated by the traditional 1 leg nonparametric method versus a new 2 leg parametric method. METHODS The study evaluated 60 children with mild asthma aged 5 to 12 years participating in a randomized controlled trial of ICSs with longitudinal concomitant assessments of LLGR and 24-hour UFC excretion. The sensitivity of the safety assessments was analyzed by comparing LLGR and 24-hour UFC in the placebo run-in period with values in the ICS treatment period by using paired t tests. Factors with a potential influence on LLGR were analyzed by means of ANOVA and the Levene test of homogeneity. RESULTS The mean LLGR was significantly reduced during the ICS versus placebo run-in periods: 0.18 mm/wk (SD, 0.55 mm/wk) versus 0.45 mm/wk (SD, 0.39 mm/wk), with a mean difference of 0.27 mm/wk (95% CI, 0.05-0.48 mm/wk; P = .02). In contrast, there was no difference in 24-hour UFC excretion: 6.91 nmol/mmol (SD, 4.67 nmol/mmol) versus 7.58 nmol/mmol (SD, 6.17 nmol/mmol), with a mean difference of 0.67 nmol/mmol (95% CI, -1.13 to 2.48 nmol/mmol; P = .46). We observed no significant difference in parametric determined LLGR caused by the child's age or sex, investigator, or season of measurement, whereas some differences were observed for the nonparametric LLGR. CONCLUSION These findings suggest that knemometry is a more sensitive pharmacodynamic measure of systemic effects of ICSs than 24-hour UFC excretion and that a parametric determination of LLGR increases the sensitivity of the method. These findings should be considered by legislative authorities in the future.

Abstract
Inhaled corticosteroids are used as one of the first-line drug therapy in patients with asthma. However, their long-term use is associated with various oropharyngeal and systemic side and adverse effects. Design of pro-soft drug is one of the strategies, which was adopted in the design of ciclesonide for mitigation of side effects usually observed with the use of inhaled corticosteroids. Ciclesonide, a pro-soft drug, is converted to an active metabolite desisobutyryl-ciclesonide in the lungs. The anti-inflammatory effect of desisobutyryl-ciclesonide is much higher than ciclesonide, and therefore, the local effect of the metabolite is higher with lower systemic side effects. Ciclesonide has favorable pharmacokinetic and pharmacodynamic properties as inhaled corticosteroid including low oral bioavailability, high plasma protein binding and rapid systemic clearance, high pulmonary deposition and distribution and long pulmonary residence duration. These advantageous properties make ciclesonide a very effective treatment option with low side effects. Various clinical studies support safety and efficacy of ciclesonide use in mild, moderate, and severe asthma patients.

Abstract
OBJECTIVES Knemometry, the precise measurement of lower leg (LL) length, suggests that childhood short-term (e.g., weekly) growth is a dynamic, nonlinear process. However, owing to the large size and complexity of the traditional knemometer device, previous study of short-term growth among children has been restricted predominantly to clinical settings in industrialized Western nations. The aim of the present study is to address this limitation and promote broader understandings of global variation in childhood development by: (1) describing a custom-built portable knemometer and assessing its performance in the field; and (2) demonstrating the potential application of such a device by characterizing childhood short-term LL growth among the indigenous Shuar of Amazonian Ecuador. MATERIALS AND METHODS Mixed-longitudinal LL length data were collected weekly from 336 Shuar children age 5-12 years old using the custom portable knemometer (n = 1,145 total observations). Device performance and Shuar short-term LL growth were explored using linear mixed effects models and descriptive statistics. RESULTS The portable knemometer performed well across a range of participant characteristics and possesses a low technical error of measurement of 0.18 mm. Shuar childhood LL growth averages 0.47 mm/week (SD = 0.75 mm/week), but exhibits large between- and within-individual variation. DISCUSSION Knemometry can be reliably performed in the field, providing a means for evaluating childhood short-term growth among genetically and ecologically diverse populations. Preliminary findings suggest that Shuar weekly LL growth is comparable in mean magnitude but likely more variable than reported for healthy Western children. Future work will further explore these patterns. Am J Phys Anthropol 160:353-357, 2016. © 2016 Wiley Periodicals, Inc.

Abstract
During recent years, extra-fine particle inhaled corticosteroids with a median aerodynamic diameter ≤2 μm have been introduced in the treatment of asthma. The aim of this paper was to review pharmacokinetics and systemic activity of extra-fine particle hydroalkane pressurized metered dose inhaled (pMDI) ciclesonide and beclomethasone dipropionate in children. A literature review was performed. Systemic bioavailability of oral and pulmonary deposition of extra-fine ciclesonide and beclomethasone dipropionate was 52% and 82%, the half-life in serum 3.2 and 1.5 h and first-pass hepatic metabolism >99% and 60%, respectively. Secondary analyses of urine cortisol/creatinine excretion found no effects of ciclesonide pMDI between 40 and 320 μg/day or of beclomethasone dipropionate pMDI between 80 and 400 μg/day. Ciclesonide pMDI 40, 80 and 160 μg/day caused no effects on short-term lower leg growth rate as assessed by knemometry. Ciclesonide 320 μg/day was associated with a numerically short-term growth suppression equivalent to 30% which was similar to 25% and 36% suppression caused by beclomethasone dipropionate HFA and CFC 200 μg/day, respectively. Consistent with the differences in key pharmacokinetic features, beclomethasone dipropionate is associated with a systemic activity detected by knemometry at a lower dose than ciclesonide. Whether that correlates with a clinically important difference remains to be explored. Assessments of systemic activity of beclomethasone dipropionate <200 μg/day and of ciclesonide >180 μg/day as well as head-to-head comparisons are warranted. Preferably, such studies should apply the sensitive method of knemometry.

Abstract
Inhaled corticosteroids (ICSs) are the cornerstone and the first stage of asthma treatment. The objective of this study was to synthesize data on the potential effects of ICSs on growth in children. Studies on the short-term impact of ICSs on growth evaluated by knemometry cannot be extrapolated to the medium or long term and therefore have no utility in real life for a given person. In the medium term, the various ICSs given at the usual doses cause a small reduction in growth after 6 months of treatment. This slowdown occurs at the beginning of treatment, especially in younger children, and the growth velocity corrects itself later but without catching up. In the long term, the prolonged use of ICSs seems to induce a small reduction in the final size in adulthood (close to 1cm) occurring in the first 2 years of treatment without worsening over time. The impact of gender, age at onset of treatment, different ICSs, modes of inhalation, and severity of asthma should also be studied further. The benefit of ICSs in asthma treatment is greater than the risk of side effects, including on growth. The majority of the therapeutic effect is obtained for small to moderate doses of ICSs. Regular adjustment of ICS dose for optimal asthma control should also reduce ICS dose and the impact on growth.

Abstract
INTRODUCTION Treatment of difficult asthma with oral corticosteroids (OCS) may suppress the hypothalamic-pituitary-adrenal axis. AIM In this study we have checked if the substitution of OCS with very high doses of ciclesonide may restore the adrenal function without losing the control of the disease. MATERIAL AND METHODS In 5 patients with difficult, uncontrolled asthma despite treatment with OCS, inhaled and systemic glucocorticosteroids were replaced with very high doses of ciclesonide (1600-2400 µg/day). The symptoms of asthma and the lung function were assessed at baseline and on the 28(th), 56(th) and 70(th) day of treatment, whereas the levels of cortisol and adrenocorticotropic hormone (ACTH) in the morning were measured at baseline and on the 28(th) and the 56(th) day of treatment. RESULTS In all patients, the control of asthma symptoms, measured with Asthma Control Test questionnaire, improved from the mean score of 9.4 to 19.8 in 70 days. In 4 subjects force expiratory volume in 1 s improved gradually through the entire study reaching a mean improvement of 585 ml in 70 days. The ACTH levels were normalized in 3 patients after 28 days of observation and in all patients after 56 days. The cortisol level was normalized in 4 patients after 28 days and in another subject after 56 days of treatment with ciclesonide. CONCLUSIONS Switching from prednisone to very high doses of ciclesonide normalized the hypothalamic-pituitary adrenal axis function and also improved the disease control and the lung function in these 5 patients with difficult asthma.

Abstract
Asthma severity is classified according to the level of treatment required to control symptoms. Inhaled corticosteroids are the recommended first-line therapy for the treatment of persistent asthma, and when asthma remains uncontrolled, one option is to increase the inhaled corticosteroids dose. However, there is a concomitant risk of increasing local and systemic adverse events, which may impact patient adherence and physician prescribing practices. Ciclesonide is delivered as a prodrug, has high peripheral lung deposition and high protein-binding capabilities, and is rapidly eliminated from the systemic circulation. This article reviews the use of high-dose ciclesonide in patients with severe asthma and considers whether the pharmacology of ciclesonide translates into it being an efficacious and well-tolerated option for patients requiring a step-up in their asthma treatment.

Abstract
Growth impairment in children with asthma, as a consequence of inhaled corticosteroids (ICS), is a major issue. Adverse systemic effects of ICS have been reviewed extensively, but no clinically relevant effects are reported if they are used in an appropriate dose as advocated in most guidelines. Growth studies can be divided into knemometry studies, intermediate term studies, and long term studies up to final adult height. These different studies provide different information. Knemometry demonstrates a dose dependent systemic effect, while all intermediate term studies demonstrate growth reduction of approximately one cm after one year of treatment. Most reassuring is that this delay seems to be temporary. The one study with a follow-up to final height shows no differences between the ICS and non-ICS treated children. The studies suggest that the use of ICS with respect to growth is safe if these drugs are used in a low to medium dose.

Abstract
BACKGROUND Inhaled corticosteroids (ICS) are the cornerstone of asthma maintenance treatment in children. Particularly among parents, there is concern about the safety of ICS as studies in children have shown reduced growth. Small-particle-size ICS targeting the smaller airways have improved lung deposition and effective asthma control might be achieved at lower daily doses.Ciclesonide is a relatively new ICS. This small-particle ICS is a pro-drug that is converted in the airways to an active metabolite and therefore with potentially less local (throat infection) and systemic (reduced growth) side effects. It can be inhaled once daily, thereby possibly improving adherence. OBJECTIVES To assess the efficacy and adverse effects of ciclesonide compared to other ICS in the management of chronic asthma in children. SEARCH METHODS We searched the Cochrane Airways Group Register of trials with pre-defined terms. Additional searches of MEDLINE (via PubMed), EMBASE and Clinical study results.org were undertaken. Searches are up to date to 7 November 2012. SELECTION CRITERIA Randomised controlled parallel or cross-over studies were eligible for the review. We included studies comparing ciclesonide with other corticosteroids both at nominally equivalent doses or lower doses of ciclesonide. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and extracted data. Study authors were contacted for additional information. Adverse effects information was collected from the trials. MAIN RESULTS Six studies were included in this review (3256 children, 4 to 17 years of age). Two studies were published as conference abstracts only. Ciclesonide was compared to budesonide and fluticasone.Ciclesonide compared to budesonide (dose ratio 1:2): asthma symptoms and adverse effect were similar in both groups. Pooled results showed no significant difference in children who experience an exacerbation (risk ratio (RR) 2.20, 95% confidence interval (CI) 0.75 to 6.43). Both studies reported that 24-hour urine cortisol levels showed a statistically significant decrease in the budesonide group compared to the ciclesonide group.Ciclesonide compared to fluticasone (dose ratio 1:1): no significant differences were found for the outcome asthma symptoms. Pooled results showed no significant differences in number of patients with exacerbations (RR 1.37, 95% CI 0.58 to 3.21) and data from a study that could not be pooled in the meta-analysis reported similar numbers of patients with exacerbations in both groups. None of the studies found a difference in adverse effects. No significant difference was found for 24-hour urine cortisol levels between the groups (mean difference 0.54 nmol/mmol, 95% CI -5.92 to 7.00).Ciclesonide versus fluticasone (dose ratio 1:2) was assessed in one study and showed similar results between the two corticosteroids for asthma symptoms. The number of children with exacerbations was significantly higher in the ciclesonide group (RR 3.57, 95% CI 1.35 to 9.47). No significant differences were found in adverse effects (RR 0.98, 95% CI 0.81 to 1.14) and 24-hour urine cortisol levels (mean difference 1.15 nmol/mmol, 95% CI 0.07 to 2.23).The quality of evidence was judged 'low' for the outcomes asthma symptoms and adverse events and 'very low' for the outcome exacerbations for ciclesonide versus budesonide (dose ratio 1:1). The quality of evidence was graded 'moderate' for the outcome asthma symptoms, 'very low' for the outcome exacerbations and 'low' for the outcome adverse events for ciclesonide versus fluticasone (dose ratio 1:1). For ciclesonide versus fluticasone (dose ratio 1:2) the quality was rated 'low' for the outcome asthma symptoms and 'very low' for exacerbations and adverse events (dose ratio 1:2). AUTHORS' CONCLUSIONS An improvement in asthma symptoms, exacerbations and side effects of ciclesonide versus budesonide and fluticasone could be neither demonstrated nor refuted and the trade-off between benefits and harms of using ciclesonide instead of budesonide or fluticasone is unclear. The resource use or costs of different ICS should therefore also be considered in final decision making. Longer-term superiority trials are needed to identify the usefulness and safety of ciclesonide compared to other ICS. Additionally these studies should be powered for patient relevant outcomes (exacerbations, asthma symptoms, quality of life and side effects). There is a need for studies comparing ciclesonide once daily with other ICS twice daily to assess the advantages of ciclesonide being a pro-drug that can be administered once daily with possibly increased adherence leading to increased control of asthma and fewer side effects.

Abstract
Inhaled corticosteroids (ICS) are mainstay treatment of asthma and chronic obstructive pulmonary disease. However, highly lipophilic ICS accumulate in systemic tissues, which may lead to adverse systemic effects. The accumulation of a new, highly lipophilic ICS, ciclesonide and its active metabolite (des-CIC) has not yet been reported. Here, we have compared tissue accumulation of des-CIC and an ICS of a moderate lipophilicity, budesonide (BUD), after 14 days of once-daily treatment in mice. Single, three or 14 daily doses of [(3) H]-des-CIC or [(3) H]-BUD were administered subcutaneously to male CD1 albino mice, which were killed at 4 hr, 24 hr or 5 days after the last dose. Distribution of tissue concentration of radioactivity was studied by quantitative whole-body autoradiography. Pattern of radioactivity distribution across most tissues was similar for both corticosteroids after a single as well as after repeated dosing. However, tissue concentration of radioactivity differed between des-CIC and BUD. After a single dose, concentrations of radioactivity for both corticosteroids were low for most tissues but increased over 14 days of daily dosing. The tissue radioactivity of des-CIC at 24 hr and 5 days after the 14th dose was 2-3 times higher than that of BUD in majority of tissues. Tissue accumulation, assessed as concentration of tissue radioactivity 5 days after the 14th versus 3rd dose, showed an average ratio of 5.2 for des-CIC and 2.7 for BUD (p < 0.0001). In conclusion, des-CIC accumulated significantly more than BUD. Systemic accumulation may lead to increased risk of adverse systemic side effects during long-term therapy.

Abstract
PURPOSE OF REVIEW Although inhaled corticosteroids (ICSs) are the mainstay of therapy in asthma, their use raises certain safety concerns. We review the articles appearing in the last year which have addressed the safety of ICSs when used in the treatment of asthma and chronic obstructive pulmonary disease (COPD). RECENT FINDINGS Recent studies suggest that patients with asthma as opposed to COPD do not experience an excess risk of pneumonia with ICS use. Patients with respiratory diseases are at increased risk of developing active tuberculosis and this excess risk is exacerbated by the use of high doses of ICSs. ICSs have systemic effects and one result appears to be an increase in the risk of diabetes onset and progression, especially at high doses of ICSs. When examining cases of glaucoma requiring therapy, there was no increase in risk with ICSs even at high current and cumulative doses. Finally, use of even high doses of ICSs during pregnancy does not appear to affect foetal adrenal function. SUMMARY ICSs are a highly effective therapy in asthma and have an excellent safety profile at the low doses usually required in asthma. Adverse effects appear mostly at higher doses.

Abstract
PURPOSE OF REVIEW Description of recent studies evaluating growth and inhaled corticosteroids. RECENT FINDINGS Corticosteroids are the gold standard of asthma maintenance treatment, but effects on growth remain controversial. This is a review of recent research in this area, which has focused on medications causing less adrenal suppression as well as alternative regimens for chronic illness such as asthma. SUMMARY The use of newer corticosteroids and regimens shows short-term evidence of minimal growth effects without worsening of asthma control.

Abstract
The treatment of children with asthma has historically relied upon expert opinion using data extrapolated from adult studies. Over the past few years, landmark studies have been completed providing healthcare professionals with evidence on which a reasonable approach can be made for children suffering from this common and serious disease. Asthmatic phenotype in children, unlike adults, tends to differ according to age, which must be taken into account as well as triggers, severity, and level of control. The care of the child with asthma is complex, but accumulating data have demonstrated that we are on the right path for optimizing control while reducing the burden of side effects. The newest Global Initiative for Asthma (GINA) guidelines, as well as recent updates from the landmark CAMP (Childhood Asthma Management Program) study and information from the PACT (Pediatric Asthma Control Trial) and budesonide/formoterol controller and reliever studies, along with recent comparisons of higher dose inhaled corticosteroids (ICS), and ICS/long-acting β(2)-adrenoceptor agonist (LABA) combination and leukotriene receptor antagonist (LTRA) therapies in children have clarified a few of the big questions in pediatric asthma. For children with asthma aged 5 years and older, the CAMP trial demonstrated that regular use of ICS reduces the frequency of symptoms; however, height was adversely affected and there is no evidence for altering the natural history of asthma. In patients aged 6 years and over whose asthma is uncontrolled on ICS alone, combination therapy with ICS and a LABA has been recently compared with the use of higher dose ICS and the addition of an LTRA in pediatric patients. The addition of a LABA statistically will be of most benefit; however, some children will have optimal control with doubling the baseline dose of ICS or addition of an LTRA. Use of budesonide/formoterol as a controller and reliever therapy extends the time to first exacerbation versus contemporary use of this medication in patients aged 4 years and older. Ciclesonide, a newer ICS, has demonstrated acceptable efficacy but has the added benefit of not affecting growth. Certainly, with mounting evidence, the care-map in pediatric asthma control is becoming clearer.

Abstract
PURPOSE Inhaled corticosteroids (ICS) improve symptoms in lung diseases, such as asthma. Initial data suggest that the effects of ICS remain localized in the lung; however, recent studies demonstrate alteration to the peripheral immune system in patients with asthma. We sought to evaluate the effect of ICS on peripheral immune mediators and hypothalamic-pituitary-adrenal axis and their response to exercise in healthy men. METHODS Eleven healthy males (18-30 yr old) were placed on 2 wk of fluticasone proprionate (440 μg) twice daily. A 30-min bout of exercise was performed on a cycle ergometer at approximately 70% of peak work rate before and after the start of ICS. Blood was sampled before and after exercise. Cytokines and hypothalamic-pituitary-adrenal axis mediators were measured by ELISA, and fluticasone was measured by liquid chromatography/tandem mass spectrometry. RESULTS After ICS treatment, cortisol and adrenocorticotropin were decreased, and a blunted exercise response was observed for cortisol, adrenocorticotropin, and growth hormone. Peripheral leukocytes and neutrophils were significantly increased in response to exercise in both the untreated and the ICS-treated conditions and at baseline after ICS treatment. Interleukin-6 was elevated with ICS treatment, but the exercise response was blunted. Circulating median fluticasone levels were 0.15 ng·mL(-1) and were increased to 0.20 ng·mL(-1) in response to exercise. CONCLUSIONS Exercise revealed deficits in growth hormone production after ICS treatment not identified by static markers. Neutrophils were shown to be surrogate markers of the systemic effect of ICS. Exercise significantly increased circulating levels of fluticasone. Exercise challenge tests can be used to assess the physiological effect of exogenous corticosteroids.

Abstract
Asthmatic syndrome, better definition of asthma, is an inflammatory chronic disease, probably the most frequent in pediatrics. An important characteristic of asthma is the bronchial inflammation with a complex network of cells and inflammatory mediators of pivotal importance in the pathogenesis. The long term control and treatment of this disease are cardinal points of the management of asthmatic syndrome. Inhaled corticosteroids (ICS) are the first-line treatment for persistent asthma in children of any age. The adverse events of the inhaled steroids on growth, bone mineralization, and hypothalamic-pituitary adrenal (HPA) axis function are the main concerns for the pediatricians. The long-term effects on growth and bone mineralization are actually reassuring. Good tolerance is achieved on hypothalamic-pituitary adrenal axis function with low to moderate doses in children. Scientific and clinical researches are pointed to find out molecules able to improve clinical efficacy of ICS with better tolerance and higher reduction of adverse events.

Abstract
OBJECTIVE To evaluate the efficacy and safety of three doses of ciclesonide (with or without spacer) in children with persistent asthma. PATIENTS AND METHODS This was a multicentre, double-blind, placebo-controlled, 12-week study of ciclesonide 40, 80 or 160 μg (once daily pm). Children (6-11 years) were randomised 1:1 to treatment via a metered dose inhaler (MDI) or MDI plus spacer. The primary variable was change from baseline in mean morning peak expiratory flow (PEF). Secondary variables included: time to first lack of efficacy (LOE), asthma control, forced expiratory volume in 1 s (FEV(1)), asthma symptom score and quality of life (QoL). Safety assessments included: adverse events (AEs), urinary cortisol excretion and body height. RESULTS In total, 1073 children received treatment. At endpoint, mean morning PEF significantly improved with all doses of ciclesonide vs. placebo. There was no difference over placebo in time to first LOE, but ciclesonide was superior to placebo on asthma control, symptom score, FEV(1) and QoL. There were no differences between the spacer or non-spacer subgroups. The incidences of AEs were comparable between treatment groups (approximately 35%) and there were no between-group differences in body height or urinary cortisol. CONCLUSIONS Ciclesonide 40-160 μg once daily is effective and well tolerated in children with persistent asthma; its efficacy and safety are unaffected by the use of a spacer. clinicaltrials.gov registration number: NCT00384189.
