Abstract
BACKGROUND Inhaled corticosteroids (ICS) are the mainstay treatment for persistent asthma. Escalating treatment is required when asthma is not controlled with ICS therapy alone, which would include, but is not limited to, adding a long-acting beta2-agonist (LABA) or a long-acting muscarinic antagonist (LAMA) or doubling the dose of ICS. OBJECTIVES To assess the efficacy and safety of adding a LABA or LAMA to ICS therapy versus doubling the dose of ICS in adolescents and adults whose asthma is not well controlled on medium-dose (MD)-ICS using a network meta-analysis (NMA), and to provide a ranking of these treatments according to their efficacy and safety. SEARCH METHODS We searched the Cochrane Airways Trials Register, CENTRAL, MEDLINE, Embase, Global Health, ClinicalTrials.gov, and the World Health Organization ICTRP for pre-registered randomised controlled trials (RCTs) from January 2008 to 19 December 2022. SELECTION CRITERIA We searched for studies including adolescents and adults with uncontrolled asthma who had been treated with or were eligible for MD-ICS, comparing it to high-dose (HD)-ICS, ICS/LAMA, or ICS/LABA. We excluded cluster- and cross-over RCTs. Studies were of at least 12 weeks duration. DATA COLLECTION AND ANALYSIS We conducted a systematic review and network meta-analysis according to a previously published protocol. We used Cochrane's Screen4ME workflow to assess search results. We used Grading of Recommendations Assessment, Development and Evaluation (GRADE) to assess the certainty of evidence. The primary outcome is asthma exacerbations (moderate and severe). MAIN RESULTS We included 38,276 participants from 35 studies (median duration 24 weeks (range 12 to 78); mean age 44.1; 38% male; 69% white; mean forced expiratory volume in one second 2.1 litres and 68% of predicted). MD- and HD-ICS/LABA likely reduce and MD-ICS/LAMA possibly reduces moderate to severe asthma exacerbations compared to MD-ICS (hazard ratio (HR) 0.70, 95% credible interval (CrI) 0.59 to 0.82; moderate certainty; HR 0.59, 95% CrI 0.46 to 0.76; moderate certainty; and HR 0.56, 95% CrI 0.38 to 0.82; low certainty, respectively), whereas HD-ICS probably does not (HR 0.94, 95% CrI 0.70 to 1.24; moderate certainty). There is no clear evidence to suggest that any combination therapy or HD-ICS reduces severe asthma exacerbations compared to MD-ICS (low to moderate certainty). This study suggests no clinically meaningful differences in the symptom or quality of life score between dual combinations and monotherapy (low to high certainty). MD- and HD-ICS/LABA increase or likely increase the odds of Asthma Control Questionnaire (ACQ) responders at 6 and 12 months compared to MD-ICS (odds ratio (OR) 1.47, 95% CrI 1.23 to 1.76; high certainty; and OR 1.59, 95% CrI 1.31 to 1.94; high certainty at 6 months; and OR 1.61, 95% CrI 1.22 to 2.13; moderate certainty and OR 1.55, 95% CrI 1.20 to 2.00; high certainty at 12 months, respectively). MD-ICS/LAMA probably increases the odds of ACQ responders at 6 months (OR 1.32, 95% CrI 1.11 to 1.57; moderate certainty). No data were available at 12 months. There is no clear evidence to suggest that HD-ICS increases the odds of ACQ responders or improves the symptom or qualify of life score compared to MD-ICS (very low to high certainty). There is no evidence to suggest that ICS/LABA or ICS/LAMA reduces asthma-related or all-cause serious adverse events (SAEs) compared to MD-ICS (very low to high certainty). HD-ICS results in or likely results in little or no difference in the included safety outcomes compared to MD-ICS as well as HD-ICS/LABA compared to MD-ICS/LABA. The pairwise meta-analysis shows that MD-ICS/LAMA likely reduces all-cause adverse events (AEs) and results in a slight reduction in treatment discontinuation due to AEs compared to MD-ICS (risk ratio (RR) 0.86, 95% confidence interval (CI) 0.77 to 0.96; 4 studies, 2238 participants; moderate certainty; and RR 0.51, 95% CI 0.26 to 0.99; 4 studies, 2239 participants; absolute risk reduction 10 fewer per 1000 participants; moderate certainty, respectively). The NMA evidence is in agreement with the pairwise evidence on treatment discontinuation due to AEs, but very uncertain on all-cause AEs, due to imprecision and heterogeneity. AUTHORS' CONCLUSIONS The review findings suggest that MD- or HD-ICS/LABA and MD-ICS/LAMA reduce moderate to severe asthma exacerbations and increase the odds of ACQ responders compared to MD-ICS whereas HD-ICS probably does not. The evidence is generally stronger for MD- and HD-ICS/LABA than for MD-ICS/LAMA primarily due to a larger evidence base. There is no evidence to suggest that ICS/LABA, ICS/LAMA, or HD-ICS/LABA reduces severe asthma exacerbations or SAEs compared to MD-ICS. MD-ICS/LAMA likely reduces all-cause AEs and results in a slight reduction in treatment discontinuation due to AEs compared to MD-ICS. The above findings may assist in deciding on a treatment option during the stepwise approach of asthma management. Longer-term safety of higher than medium-dose ICS needs to be addressed in phase 4 or observational studies given that the median duration of included studies was six months.

Abstract
Standing height is an essential anthropometric measurement in pediatrics. In children unable to stand upright, measurement of ulna to predict standing height is recommended, but height prediction equations based on the ulna have not been established in children of African ancestry. We hypothesized that such equations would result in lower predicted height compared to using equations derived from non-African children. We measured prospectively standing height and both ulna in 358 African-Caribbean children without bone deformity or muscle disease, referred to two pulmonary function test laboratories. Interobserver variability was low for standing height (n = 54) and ulna measurement (n = 51) (mean biases [95%CI]: -0.02 [-0.99; 0.95] and 0.05 [-0.91; 1.01] cm, respectively), as well as inter-ulna variability (n = 352; mean bias 0.03 95%CI [-0.66; 0.73] cm). We used the mean value of 247 bilateral ulna measurements to calculate prediction equations using a generalized linear model including age, sex, ulna length, and geographic origin group, the latter showing no influence on the model. In the validation population of 107 children, the median difference [inter-quartile range] between standing height and ulna-predicted height was -0.4 [-2.7; 1.0] cm. Of 260 reliable baseline spirometry, there was a strong concordance between bronchial obstruction diagnosis established using standing height or ulna-predicted height (kappa coefficient: 0.85 [0.77; 0.94]) with only 11 (4.3%) children misclassified. The ulna predicted height calculated from African-Caribbean prediction equations resulted in a smaller height than the height calculated using equations derived from non-African children.

Abstract
BACKGROUND Infants and young children might be particularly susceptible to the potential side effects from inhaled corticosteroid (ICS) on height and bone mineral content (BMC), but this has rarely been studied in long-term prospective studies. METHODS Children from two Copenhagen Prospective Studies on Asthma in Childhood cohorts were included. ICS use was registered prospectively from birth to age 6 and the cumulative dose was calculated. Primary outcomes were height and BMC from dual-energy X-ray absorptiometry (DXA) scans at age 6. RESULTS At age 6, a total of 930 children (84%) from the cohorts had a valid height measurement and 792 (71%) had a DXA scan. 291 children (31%) received a cumulated ICS dose equivalent to or above 10 weeks of standard treatment before age 6. We found an inverse association between ICS use and height, -0.26 cm (95% CI: -0.45 to -0.07) per 1 year standard treatment from 0 to 6 years of age, p=0.006. This effect was mainly driven by children with ongoing treatment between age 5 and 6 years (-0.31 cm (95% CI: -0.52 to -0.1), p=0.004), while there was no significant association in children who stopped treatment at least 1 year before age 6 (-0.09 cm (95% CI: -0.46 to 0.28), p=0.64). There was no association between ICS use and BMC at age 6. CONCLUSIONS ICS use in early childhood was associated with reduced height at age 6 years but only in children with continued treatment in the sixth year of life.

Abstract
Asthma is a common chronic airways disease with significant impact on patients, caregivers, and the health-care system. Although most research and novel interventions mainly have focused on patients with uncontrolled severe asthma, most patients with asthma have mild disease. Epidemiologic studies suggest that many patients with mild asthma report frequent exacerbations of the disease and uncontrolled symptoms. However, despite its impact, mild asthma does not have either a uniformly agreed on definition for or a consensus on its clinical and pathophysiologic progression. More recently, the approach to treatment of patients with mild asthma has undergone significant changes primarily based on emerging evidence that airway inflammation in this population is important. This led to clinical research studies that explored the efficacy of as-needed inhaled corticosteroids along with the rescue medications that traditionally have been the mainstay of treatment. Despite some advancement in the field in recent years, many controversies and unmet needs remain. In this review, we examine the current understanding of the pathophysiologic features and management of mild asthma. In addition, we outline unmet needs for future research. We conclude that mild asthma contributes significantly to the morbidity and mortality of asthma and should be the focus of future research.

Abstract
OBJECTIVES To address concerns related to the safety profile of both Food and Drug Administration (FDA)-approved and non-FDA-approved intranasal corticosteroid (INCS) use in the pediatric population. DATA SOURCE Systematic review of MEDLINE, PubMed, and EMBASE databases using comprehensive search strategy, including all INCS formulations and adverse events. The study design was developed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Additional sources were identified from study references of relevant articles. REVIEW METHODS A structured literature search was conducted. Extracted data included age, population size, study design, drug (dosage, route, and frequency), presence of hypothalamic-pituitary-adrenal (HPA) axis suppression, ocular symptoms, and growth velocity adverse events. RESULTS A total of 33 studies met inclusion criteria. The studies included use of INCS as nasal sprays and drops. There were no persistent abnormalities noted in cortisol level or intraocular pressure change. Growth velocity reduction was reported in 3 of 10 randomized trials. Meta-analysis of epistaxis and headache showed no significant difference in the incidence of headache or epistaxis when FDA-approved INCSs were compared to placebo, with a relative risk of 1.12 (95% CI, 0.77-1.63; P = .56) and 0.84 (95% CI, 0.60-1.18; P = .32), respectively. Meta-analysis was not performed for growth velocity, HPA axis suppression, and ocular change. CONCLUSIONS INCSs in FDA-approved routes of administration are generally safe to use in the pediatric population. Use of non-FDA-approved INCS drops may increase risk of iatrogenic Cushing's syndrome. Growth velocity reduction, HPA axis suppression, and visual changes due to INCS are uncommon.

Abstract
Exposure to particulate matter (PM) has been known to be one of the risk factors to cause allergic asthma, leading to development of respiratory disease. Banhahubak-tang tablet (BHT), a standardized Korean Medicine, is prescribed for neurasthenia, laryngopharyngitis and asthma. In this study, we investigated therapeutic effects of BHT on airway inflammation in ovalbumin (OVA) and PM smaller than 10 μm (PM10)-induced allergic asthma mice. To establish allergic asthma with airway hyper-responsiveness by PM10, BALB/c mice were sensitized and challenged with OVA and PM10, and orally administered BHT. Histological staining was performed to assess airway remodeling. Serum and bronchoalveolar lavage fluid (BALF) was collected for measuring immunoglobulin levels and counting inflammatory cells, respectively. Expression levels of Janus kinase 1 (JAK1)/signal transducer and activator of transcription 6 (STAT6), pro-inflammatory cytokines and type 2 T-helper (Th2)-related cytokines were analyzed in vivo and in vitro models. Histopathological analysis demonstrated that BHT suppressed inflammatory cell infiltration, mucus hypersecretion and collagen deposition in the airway. BHT administration effectively decreased number of inflammatory cells in BALF. BHT reduced total serum Immunoglobulin E (IgE) and Immunoglobulin G (IgG) levels. In addition, BHT significantly inhibited the phosphorylation of JAK1 and STAT6 expressions. Release of pro-inflammatory cytokines and Th2-related cytokines were down-regulated by BHT. In conclusion, BHT mitigated airway inflammation by down-regulating pro-inflammatory and Th2-related cytokines via JAK1/STAT6 signaling. BHT might be a promising herbal medicine for preventing airway inflammation. Moreover, an intervention study among humans is needed to further evaluate the possible beneficial effects of BHT in allergic asthma.

Abstract
Asthma is the most common chronic inflammatory disease of children. Inhaled corticosteroids (ICS) are the cornerstone of asthma therapy which are the most effective, commonly used treatment of persistent asthma. Mostly, studies on the relationship between asthma and cortisol have focused on side effects of treatment. Recently, asthmatic patients not treated with ICS have been reported to have an attenuated activity and/or responsiveness of their Hypothalamic-Pituitary- Adrenal (HPA) axis. Moreover, it has been proposed that asthma worsening with stress may be due to a dysfunctional HPA axis, or cortisol insensitivity due to chronic psychological stress through impaired glucocorticoid receptor expression or function. Although long-term ICS treatment might produce adrenal suppression or iatrogenic Cushing syndrome, improvement of adrenal function has also been detected in some of asthmatic cases. Thus, the response scheme of HPA axis still contains undiscovered features in asthma. The management of asthma can be improved by increasing knowledge on the role of HPA axis in asthma pathophysiology. The risk for side effects of ICS can be minimized through increased awareness, early recognition of at-risk patients and regular patient follow-up. This review was written to draw attention to the role of HPA axis in both asthma and its treatment and to illustrate a follow up algorithm of HPA axis in the management of asthma.

Abstract
BACKGROUND Symptom-based adjustment (SBA) of inhaled corticosteroids may be an alternative patient-centered approach in which day-to-day inhaled corticosteroid use is adjusted by symptoms and short-acting β-agonist need. OBJECTIVE To evaluate the effectiveness of SBA in the primary care setting. METHODS We conducted a randomized, open-label, pragmatic equivalence trial in African-American children (6-17 years old) with mild asthma managed by 12 primary care providers (PCPs). A total of 206 participants were randomized to SBA (as-needed beclomethasone 80 μg with rescue short-acting β-agonist) or provider-based guideline-directed adjustment (PBA): maintenance beclomethasone 80 μg/d (6-11 years old), 160 μg/d (12-17 years old), with subsequent guideline-based dose adjustment by PCPs. PCPs implemented both treatment assignments, with outcomes measured by blinded staff. All participants received symptom recognition and albuterol use education from peer educators. Primary outcome was change in asthma control (measured by Asthma Control Test [ACT]/childhood ACT [cACT]) over 12 months. RESULTS Participants had adequately controlled asthma (mean ACT or cACT score = 21.6 ± 2.8) at baseline. After 1 year, there was no significant between-group difference in change in ACT scores (SBA - PBA): ACT: -0.88 (95% CI, -2.19 to 0.42), cACT: -0.73 (-2.09 to 0.62), or combined ACT and cACT (P = .10), and was within the predefined statistical clinical equivalence. The proportion with an exacerbation and measures of lung function were similar between groups. Compared with PBA, SBA led to less beclomethasone use (SBA: 526 μg/mo [95% CI, 412-639 μg] vs PBA: 1961 μg/mo [95% CI, 1681-2241]; P < .0001). More parents in the SBA arm felt they were managing their child's asthma. CONCLUSIONS SBA in African-American children with mild asthma was similar to PBA in asthma control and events when implemented by PCPs with lower inhaled corticosteroid exposure.

Tiotropium add-on therapy is safe and reduces seasonal worsening in paediatric asthma patients. Eur Respir J 2019; 53:13993003.01824-2018. [PMID: 31097514 PMCID: PMC6581158 DOI: 10.1183/13993003.01824-2018] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2018] [Accepted: 03/19/2019] [Indexed: 11/05/2022]
Abstract
There remains an unmet need for effective, well-tolerated therapeutic options in paediatric patients with not fully controlled asthma, for whom safety is of paramount importance.Data were pooled from five randomised, double-blind, placebo-controlled studies evaluating tiotropium 5 or 2.5 µg versus placebo add-on therapy in patients with symptomatic asthma aged 1-17 years. Analysis included adverse events (AEs) and serious AEs (SAEs) reported throughout and for 30 days following treatment.Of 1691 patients treated, 1119 received tiotropium. Reporting of AEs was low and comparable across all groups: tiotropium 5 µg (51%), tiotropium 2.5 µg (51%) and placebo (54%). Reporting of drug-related AEs, those leading to discontinuation and SAEs was also low and balanced between treatment groups, irrespective of age, disease severity or sex. The number of AEs related to asthma symptoms and exacerbations was lower with tiotropium (5 µg) than with placebo, particularly during the seasonal peaks of these AEs.This comprehensive analysis of a large safety database allowed subgroup analyses that are often impractical with individual trials and provides further support for the safety of once-daily tiotropium Respimat add-on therapy in paediatric patients with symptomatic asthma.

Abstract
Despite major advances in therapeutic interventions and the availability of detailed treatment guidelines, a high proportion of patients with symptomatic asthma remain uncontrolled. Asthma management is largely guided by the Global Initiative for Asthma (GINA) strategy and is based on a backbone of inhaled corticosteroid (ICS) therapy with the use of additional therapies to achieve disease control. Inhaled long-acting bronchodilators alone and in combination are the preferred add-on treatment options. Although long-acting muscarinic antagonists (LAMAs) are a relatively recent addition to disease management recommendations for asthma, tiotropium has been extensively studied in a large clinical trial program. In Europe and the United States, tiotropium is approved for patients aged ≥6 years and uncontrolled on medium- to high-dose ICS/long-acting β2-agonists at GINA Steps 4 and 5 with a history of exacerbations. Evidence supports the efficacy of tiotropium Respimat® in adults in terms of lung function and asthma control, with a safety profile comparable with that of placebo across a range of asthma severities. Similarly, clinical trials in patients aged 1-17 years have shown improvements in lung function and trends toward improved asthma control. Furthermore, its efficacy makes tiotropium relatively easy to incorporate into routine clinical practice, irrespective of allergic status and without the need for patient phenotyping. Tiotropium is a cost-effective treatment that may offer an important alternative to other, more expensive add-on therapies. This review discusses the potential future position of LAMAs in clinical practice by considering the continuously evolving evidence. Prominence is given to tiotropium, the only LAMA supported by a structured clinical trial program in asthma to date, while also considering other recommended treatment options for patients with uncontrolled asthma. The importance of effective patient/caregiver-clinician communication and shared decision-making in enhancing treatment adherence is also highlighted.

Abstract
Globally, asthma is one of the most common chronic conditions that affect individuals of all ages. When poorly controlled, it negatively impacts patient's ability to enjoy life and work. At the population level, effective use of recommended strategies in children and adults can reduce symptom burden, improve quality of life and significantly reduce the risk of exacerbation, decline of lung function and asthma-related death. Inhaled corticosteroid as the initial maintenance therapy, ideally started within 2 years of symptom onset, is highly effective in both children and adults and across various degrees of asthma severity. If asthma is not controlled, the choice of subsequent add-on therapies differs between children and adults. Evidence supporting pharmacological approach to asthma management, especially for those with more severe disease, is more robust in adults compared to children. This is, in part, due to various challenges in the diagnosis of asthma, in the recruitment into clinical trials and in the lack of objective outcomes in children, especially those in the preschool age group. Nevertheless, where evidence is emerging for younger children, it seems to mirror the observations in adults. Clinicians need to develop strategies to implement guideline-based recommendations while taking into consideration individual variations in asthma clinical phenotypes, pathophysiology and treatment responses at different ages.

Abstract
Asthma is a major pediatric respiratory morbidity requiring long-term management. A thorough knowledge of long-term medication side-effects in children is, thus, essential for every physician dealing with childhood asthma. Establishing diagnosis and initiating treatment is just a beginning of the journey. Ongoing monitoring is an essential component of comprehensive asthma management programme. Monitoring includes not only assessment of asthma control but also checking for adherence to treatment, technique of inhaler device use, associated co-morbities, if any, and potential environmental exposure. Various tools - both subjective and objective - are available for assessment of asthma control. However, evidence for their optimum use in different settings and patient groups is lacking and monitoring has to be customized depending on available resources and individual patient characteristics. Patient education is an important component of long-term asthma therapy. The ultimate aim is to achieve optimum asthma control i.e., achieve and maintain control of clinical symptoms, decrease future risk to patients (risk of exacerbations, progressive loss of lung function and development of fixed airflow obstruction, adverse effects of medications) and enabling the child to lead a life without restrictions, at lowest possible dose of drugs. This article reviews the side-effects of medications used for long-term management of asthma and discusses current literature on asthma monitoring and dose titration in pediatric population to help the asthma therapist not only prescribe the drugs rationally but also help the family make right choices for treatment.

Abstract
Despite international initiatives to promote clinical research in pediatrics, there are still many gaps of knowledge in the use of drugs to treat this specific population. When important information cannot be derived only from clinical trials, use of available observational research tools is required. In this paper, we provide an overview of the particular interest of pharmacoepidemiological research into the evaluation of drug effects in children and adolescents. We also sought to underline the unique challenges and specific needs regarding this research. Implementation of innovative methodologies and expansion of database networks to perform necessary studies could further improve performances of observational research.

Abstract
BACKGROUND Few studies have assessed the safety and efficacy of potential asthma medications in children younger than 5 years. We descriptively assessed the safety and efficacy of tiotropium, a long-acting anticholinergic drug, in children aged 1-5 years with persistent asthmatic symptoms. METHODS This exploratory 12-week, randomised, double-blind, placebo-controlled, parallel-group, phase 2/3, regulatory multicentre trial was done at 32 hospitals, clinics, and clinical research units in 11 countries in Asia, Europe, and North America. Children aged 1-5 years with at least a 6-month history of persistent asthmatic symptoms and a need for inhaled corticosteroids were eligible. Patients were randomly allocated using an interactive voice or web-based response system to receive once-daily tiotropium 2·5 μg, tiotropium 5 μg, or placebo as an add-on to inhaled corticosteroids with or without additional controller medication. Patients and investigators were masked to study group assignment. Tiotropium was given via the Respimat inhaler once daily as two puffs of 1·25 μg in the 2·5 μg group, two puffs of 2·5 μg in the 5 μg group, or two puffs of placebo. The primary outcomes were safety, which was assessed by comparing adverse events between the tiotropium and placebo groups, and efficacy, which was measured as the change in weekly mean combined daytime asthma symptom score from baseline to week 12. Statistical analyses of treatment effects were exploratory; although endpoints were defined, they were used for descriptive analyses only. The safety and primary analyses were done in all patients who received at least one dose of their assigned treatment. This study is registered with ClinicalTrials.gov (NCT01634113), and is completed. FINDINGS Between July 26, 2012, and Dec 4, 2014, 102 children were randomly assigned to the three treatment groups (36 to receive tiotropium 2·5 μg, 32 to receive tiotropium 5 μg, and 34 to receive placebo). 101 children completed the study and were included in the analyses. The changes in adjusted weekly mean combined daytime asthma symptom scores between baseline and week 12 were not significantly different between any of the groups. The adjusted mean difference between the tiotropium 2·5 μg group and placebo group was -0·080 (95% CI -0·312 to 0·152) and the difference between tiotropium 5 μg and placebo group was -0·048 (-0·292 to 0·195). Adverse events were less frequent with tiotropium treatment than with placebo (20 [56%] of 36 children with tiotropium 2·5 μg, 18 [58%] of 31 with tiotropium 5 μg, and 25 [74%] of 34 with placebo), although no formal statistical comparison between groups was performed. A greater proportion of children reported asthma exacerbations as adverse events in the placebo group (ten [29%] of 34) than in the tiotropium groups (five [14%] of 36 in the 2·5 μg group and two [6%] of 31 in the 5 μg group). Serious adverse events were reported in three patients (all of whom received placebo); no adverse events led to discontinuation of treatment or death. INTERPRETATION To our knowledge, our small study is the first to assess the safety and efficacy of tiotropium in children aged 1-5 years with persistent asthmatic symptoms. Tolerability of tiotropium was similar to that of placebo, which is consistent with previous findings in older populations. Although mean daytime asthma symptom scores were not significantly different between groups, tiotropium showed the potential to reduce asthma exacerbation risk compared with placebo. The findings of the study are limited by the small sample size and descriptive statistical analyses. Additional well powered trials are needed to further assess the safety and efficacy of tiotropium in young children. FUNDING Boehringer Ingelheim.

Abstract
Chronic respiratory disease can affect growth and nutrition, which can influence lung function. We investigated height, body mass index (BMI), and lung function in patients with primary ciliary dyskinesia (PCD).In this study, based on the international PCD (iPCD) Cohort, we calculated z-scores for height and BMI using World Health Organization (WHO) and national growth references, and assessed associations with age, sex, country, diagnostic certainty, age at diagnosis, organ laterality and lung function in multilevel regression models that accounted for repeated measurements.We analysed 6402 measurements from 1609 iPCD Cohort patients. Height was reduced compared to WHO (z-score -0.12, 95% CI -0.17 to -0.06) and national references (z-score -0.27, 95% CI -0.33 to -0.21) in male and female patients in all age groups, with variation between countries. Height and BMI were higher in patients diagnosed earlier in life (p=0.026 and p<0.001, respectively) and closely associated with forced expiratory volume in 1 s and forced vital capacity z-scores (p<0.001).Our study indicates that both growth and nutrition are affected adversely in PCD patients from early life and are both strongly associated with lung function. If supported by longitudinal studies, these findings suggest that early diagnosis with multidisciplinary management and nutritional advice could improve growth and delay disease progression and lung function impairment in PCD.

Abstract
Objective To describe recovery of adrenal insufficiency in asthmatic children treated with inhaled corticosteroids (ICS) and cortisol replacement therapy. Design Retrospective, observational study. Patients A total of 113 patients, 74 male; age 10.4 (3.3–16.5) years; beclomethasone-equivalent ICS dose, 800 μg, (100–1,000), tested by low dose short Synacthen (tetracosactide) test (LDSST), were studied. Test results were classified by basal and peak cortisol concentration: “normal” (basal >100 nmol/L, peak >500 nmol/L), “suboptimal” (basal >100 nmol/L, peak 350–499 nmol/L), “abnormal” (basal <100 nmol/L and/or peak <350 nmol/L). Patients with suboptimal results received hydrocortisone during periods of stress only, and those with abnormal responses received daily hydrocortisone, increased during periods of stress. A total of 73 patients (68%) had ≥2 LDSSTs over 2.2 years (0.2–7.7). Measurements Change in cortisol response to repeat LDSST (movement between diagnostic groups, difference in basal and peak cortisol >15% [2× the inter-assay coefficient of variation]), change in BMI and height standard deviation score (SDS). Results Baseline test results were abnormal in 17 patients (15%) and all of them had repeat tests. In 13 patients (76%), test results improved (normal in six, suboptimal in seven) and four (24%) remained abnormal. Baseline tests results were suboptimal in 54 patients (48%), of whom 50 (93%) were retested. Repeat tests were normal in 36 patients (72%), remained suboptimal in 11 (22%), and were abnormal in three (6%). Baseline tests results were normal in 42 patients, of whom six patients (14%) were retested. Results remained normal in three (50%), were suboptimal in two (33%), and abnormal in one (17%). Basal and peak cortisol levels increased by >15% in 33/73 (45%) and 42/73 (57%) patients, respectively, and decreased by >15% in 14/73 (19%) and 7/73 (10%), respectively. There was no significant change in height or BMI SDS. Conclusion Recovery of adrenal function is common and occurs during continued ICS and cortisol replacement therapy.

Abstract
Stimulant medications for the treatment of attention deficit hyperactivity disorder (ADHD) and inhaled corticosteroids (ICS) for the treatment of asthma are two classes of medications that are commonly prescribed in pediatrics. Among other adverse effects of these medications, growth attenuation has long been a focus of investigation. With stimulants, growth deficits of 1-1.4 cm/year have been observed in the short term, mainly in the first 2 years of treatment, in a dose-dependent manner. Long-term studies on stimulants have reported divergent effects on growth, with many studies showing no clinically significant height deficits by adulthood. The study that followed the largest cohort of children on stimulants, however, reported an overall adult height deficit of 1.29 cm in subjects who had received stimulant medications, with mean adult height deficit of 4.7 cm among those taking the medication consistently. With ICS use, mild growth suppression is seen in the short term (particularly in the first year of therapy) with growth rates reduced by 0.4-1.5 cm/year. Available current evidence indicates that the impact of ICS use on adult height is not clinically significant, with effects limited to 1.2 cm or less. There is significant individual variability in growth suppression with ICS use, with the specific pharmacologic agent, formulation, dose exposure, age, puberty, medication adherence, and timing of administration being important modifying factors. Based on currently available evidence, the therapeutic benefits of ICS for management of asthma and stimulant medications for management of ADHD outweigh the potential risk for growth suppression. Strategies to minimize growth attenuation and other potential adverse effects of these medications include using the lowest efficacious dose, frequent assessments and dose titration. Particular vigilance is essential with concomitant use of multiple medications that can attenuate growth and to evaluate for potential adrenal insufficiency from ICS use.

PLoS One 2017; 12:e0182738. [PMID: 28793336 PMCID: PMC5549998 DOI: 10.1371/journal.pone.0182738] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2016] [Accepted: 07/24/2017] [Indexed: 12/16/2022] Open
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
INTRODUCTION Asthma is the most common chronic disease in childhood, affecting approximately 10% of all children, and is the leading cause of hospitalization in developed countries. In this paper we aimed to review the evidence on chemical pharmacotherapy for long-term treatment of pediatric asthma, according to the latest updates. Area covered: Long-term treatment, essential for controlling symptoms and reducing future risks including exacerbations and decline in lung function, includes control agents such as inhaled corticosteroids, long-acting beta2-adrenergic agonists, and leukotriene modifiers. More recent strategies based on the use of a biological drug such as omalizumab, which is a monoclonal antibody directed against immunoglobulin E (IgE), can be considered in selected patients with severe asthma. Expert opinion: In the near future, the challenge of childhood asthma treatment will be to improve the chemical drugs that already exist as well as to carefully characterize the several different asthma subtypes, with special regard to children with severe disease. A better definition of patient features, made possible by the current advanced knowledge of the pathobiology of severe asthma, can ultimately allow the identification of specific phenotypes and endotypes of severe asthma, aimed to personalize pharmacological treatment.

Abstract
For any kind of therapeutic intervention in allergic diseases such as environmental control, pharmacological, or immunomodulating treatment including educational programs, children are addressed separately from adults. Health authorities like the Food and Drug Administration in the United States of America or the European Medicine Agency in Europe request a specific 'Pediatric investigational plan' with studies addressing dose-response relationship, safety, and efficacy for infants, children, and adolescents. During the last 2 years, promising advances have been reported for the treatment of a variety of allergic and immunologic disorders. This review summarizes the progress in the treatment of pediatric asthma and allergic diseases, based on publications of approximately the last 2.5 years (end of 2013 until May 2016) in and beyond this journal. Meanwhile, it highlights areas with promising novel therapeutic approaches, which are likely to change treatment for allergic children in the near future.

Abstract
Despite the availability of several formulations of inhaled corticosteroids (ICS) and delivery devices for treatment of childhood asthma and despite the development of evidence-based guidelines, childhood asthma control remains suboptimal. Improving uptake of asthma management plans, both by families and practitioners, is needed. Adherence to daily ICS therapy is a key determinant of asthma control and this mandates that asthma education follow a repetitive pattern and involve literal explanation and physical demonstration of the optimal use of inhaler devices. The potential adverse effects of ICS need to be weighed against the benefit of these drugs to control persistent asthma especially that its safety profile is markedly better than oral glucocorticoids. This article reviews the key mechanisms of inhaled corticosteroid action; recommendations on dosage and therapeutic regimens; potential optimization of effectiveness by addressing inhaler technique and adherence to therapy; and updated knowledge on the real magnitude of adverse events.

Pediatr Allergy Immunol 2016; 27:499-506. [PMID: 26919136 DOI: 10.1111/pai.12558] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 02/21/2016] [Indexed: 12/31/2022]
Abstract
BACKGROUND Controversial data exist on the possibility that inhaled corticosteroids (ICs) affect growth in children with mild-to-moderate asthma. We assessed whether ICs affect growth and final height (FH) in asthmatic children compared to controls. METHODS A retrospective study was conducted on 113 asthmatic children compared with 66 control children. Asthmatic children presented with mild-to-moderate asthma and had exclusive ICs. Anthropometric data of four specific time-points were collected for both groups (pre-puberty, onset and late puberty, and FH) and converted to standard deviation scores (SDS). Growth trajectories were assessed as follows: (i) in puberty, using peak height velocity (PHV) and pubertal height gain SDS (PHG-SDS); (ii) until FH achievement, using FH-SDS and FH gain SDS (FHG-SDS). Repeated measurement analysis was performed across longitudinal study visits. A general linear model (GLM) was performed in asthmatic group evaluating the effect of corticosteroid type, treatment duration, and cumulative dose on FH corrected for multiple variables. RESULTS At pre-puberty, height and weight SDS were similar between the groups (p > 0.05). Height SDS progressively declined over the study period in asthmatic patients from pre-puberty to FH (p-trend < 0.05), whereas it did not change over time in controls (p-trend > 0.05), in both boys and girls. Asthmatic children had exclusive ICs [budesonide (n = 36) vs. fluticasone (n = 43) vs. mometasone (n = 34)] for a mean period of 6.25 ± 1.20 years and a mean cumulative dose of 560.07 ± 76.02 mg. They showed decreased PHG-SDS and lower PHV compared to controls (all p < 0.05). FH-SDS and FHG-SDS were significantly reduced in asthmatic group compared to controls. FH in asthmatic patients was 2.5 ± 2.89 cm lower in boys and 2.0 ± 2.03 cm lower in girls than controls. The GLM showed that FH achievement was dependent on the type of ICs, duration of the treatment, and cumulative dose (p < 0.05). CONCLUSIONS ICs affect pubertal growth determining reduced final height in asthmatic children compared to controls, in a dose- and duration-dependent manner.

Abstract
The skeletal effects of inhaled glucocorticoids are poorly understood. Children with asthma treated with inhaled glucocorticoids have lower growth velocity, bone density, and adult height. Studies of adults with asthma have reported variable effects on BMD, although prospective studies have demonstrated bone loss after initiation of inhaled glucocorticoids in premenopausal women. There is a dose-response relationship between inhaled glucocorticoids and fracture risk in asthmatics; the risk of vertebral and non-vertebral fractures is greater in subjects treated with the highest doses in the majority of studies. Patients with COPD have lower BMD and higher fracture rates compared to controls, however, the majority of studies have not found an additional detrimental effect of inhaled glucocorticoids on bone. While the evidence is not conclusive, it supports using the lowest possible dose of inhaled glucocorticoids to treat patients with asthma and COPD and highlights the need for further research on this topic.

Abstract
Drug toxicity is, unfortunately, a significant problem in children both in the hospital and in the community. Drug toxicity in children is different to that seen in adults. At least one in 500 children will experience an adverse drug reaction each year. For children in hospital, the risk is far greater (one in ten). Additionally, different and sometimes unique adverse drug reactions are seen in the paediatric age groups. Some of the major cases of drug toxicity historically have occurred in neonates. It is important that we understand the mechanism of action of adverse drug reactions. Greater understanding alongside rational prescribing should hopefully reduce drug toxicity in children in the future.

Abstract
In recent years, much effort has been directed at redefining malnutrition in the pediatric population to include the acute clinical population in addition to the more traditional ambulatory populations. In 2013, an expert panel convened to perform a critical review of available literature to craft a new approach to malnutrition. Closely thereafter, the Academy of Nutrition and Dietetics and the American Society for Parenteral and Enteral Nutrition published recommended indicators for the identification and documentation of malnutrition in pediatric populations. The purpose of this article is to review the domains within the new definition of malnutrition in pediatric practice, describe populations in which the recommended indicators for identification and management are problematic in clinical practice, give case studies that apply the new definition, and finally describe the implementation of a malnutrition identification program within a large tertiary care children's hospital.

Abstract
Preschool children (ie, those aged 5 years or younger) with wheeze consume a disproportionately high amount of health-care resources compared with older children and adults with wheeze or asthma, representing a diagnostic challenge. Although several phenotype classifications have been described, none have been validated to identify individuals responding to specific therapeutic approaches. Several risk factors related to genetic, prenatal, and postnatal environment are associated with preschool wheezing. Findings from several cohort studies have shown that preschool children with wheeze have deficits in lung function at 6 years of age that persisted until early and middle adulthood, suggesting increased susceptibility in the first years of life that might lead to persistent sequelae. Daily inhaled corticosteroids seem to be the most effective therapy for recurrent wheezing in trials of children with interim symptoms or atopy; intermittent high-dose inhaled corticosteroids are effective in moderate-to-severe viral-induced wheezing without interim symptoms. The role of leukotriene receptor antagonist is less clear. Interventions to modify the short-term and long-term outcomes of preschool wheeze should be a research priority.
