PURPOSE: Guidelines need to be tailored to where they are applied. We aimed to describe the distinctive asthma severity profile and the pattern of controller prescription in Korean children. METHODS: Twelve pediatric allergists from tertiary medical centers reviewed medical records of all asthmatic children who visited their clinics between September 1 and November 30 of 2013. Controller prescriptions were re-classified into 4 categories, then the prevalence of each asthma severity category and the controller prescription patterns according to asthma severity assessed by a Western (Global Initiative for Asthma, GINA) and an Asia-Pacific (Japanese Pediatric GuideLine, JPGL) guideline were evaluated...

Against recurrent controversies around the safety of short- and long-acting β2-agonists (SABA and LABA), and the National Review of Asthma Deaths inquiry in the United Kingdom, we investigated the prevalence of inappropriate therapy in asthma. Our study aimed to determine the prevalence of inappropriate use of asthma therapy in the United Kingdom and in France. Two interval, parallel, population-based cohorts (2007 and 2013) were developed in each country by using the UK OPCRD and the French EGB databases...

INTRODUCTION: Long-acting β2-agonists (LABAs) combined with inhaled corticosteroids (ICSs) are still commonly prescribed to asthmatic children. Unfortunately, pediatric LABA use is based primarily on data from adults, despite the fact that children are not simply small adults and the magnitude of changes in dose exposure and/or exposure response may not be solely reflected by differences in body weight. AREAS COVERED: The differences in pharmacokinetics (PK) and pharmacodynamics (PD) of LABAs are described and discussed with reference children and adults...

Asthma is a chronic inflammatory airway disease, and its treatment is frequently challenging despite detailed national and international guidelines. While basic anti-inflammatory therapy usually consists of inhaled corticosteroids in doses adapted to the asthma severity, add-on treatment with bronchodilators is essential in more severe asthma. Only recently, the long-acting anticholinergic tiotropium was introduced into the GINA guidelines. This review reports on the studies that have been performed with tiotropium in adult asthmatic patients...

BACKGROUND: Vilanterol (VI) is a long-acting beta2-agonist (LABA) that binds to the beta2-adrenoceptor on the airway smooth muscle, producing bronchodilation. LABA therapy, which is well established in adults as part of the British Thoracic Society (BTS) Guidelines for the Management of Asthma, leads to improvement in symptoms and lung function and reduction in exacerbations. At present, the commonly used LABAs licensed for use in asthma management (formoterol and salmeterol) require twice-daily administration, whereas VI is a once-daily therapy...

BACKGROUND: Long-acting beta-agonists (LABAs) have been shown to increase the risk of asthma-related death among adults and the risk of asthma-related hospitalization among children. It is unknown whether the concomitant use of inhaled glucocorticoids with LABAs mitigates those risks. This trial prospectively evaluated the safety of the LABA salmeterol, added to fluticasone propionate, in a fixed-dose combination in children. METHODS: We randomly assigned, in a 1:1 ratio, children 4 to 11 years of age who required daily asthma medications and had a history of asthma exacerbations in the previous year to receive fluticasone propionate plus salmeterol or fluticasone alone for 26 weeks...

BACKGROUND: Adding a long-acting β2-agonist (LABA) to inhaled corticosteroids (ICS) using a fixed-dose combination (FDC) inhaler is the UK guideline recommendation for children aged more than 4 years with uncontrolled asthma. The evidence of benefit of adding an FDC inhaler over a separate LABA inhaler is limited. OBJECTIVE: The objective of this study was to compare the effectiveness of a LABA added as an FDC inhaler, and as a separate inhaler, in children with uncontrolled asthma...

BACKGROUND: The Gly-to-Arg substitution at the 16 position (rs1042713) in the β2-adrenoceptor gene (ADRB2) is associated with enhanced downregulation and uncoupling of β2-receptors. OBJECTIVES: We sought to undertake a meta-analysis to test the hypothesis that there is an interaction between the A allele of rs1042713 (Arg16 amino acid) and long-acting β-agonist (LABA) exposure for asthma exacerbations in children. METHODS: Children with diagnosed asthma were recruited in 5 populations (BREATHE, Genes-Environments and Admixture in Latino Americans II, PACMAN, the Paediatric Asthma Gene Environment Study, and the Pharmacogenetics of Adrenal Suppression with Inhaled Steroid Study)...

BACKGROUND: Safety concerns associated with long-acting β2-agonists (LABAs) have led to many US Food and Drug Administration (FDA) regulatory activities for this class of drugs. Little is known about the effect of these regulatory activities on use of LABA-containing agents or other asthma medications. METHODS: We created rolling cohorts of pediatric and adult asthmatic patients in the Mini-Sentinel Distributed Database between January 2005 and June 2011. The proportions of asthmatic patients using LABA-containing products, inhaled corticosteroids (ICSs), leukotriene modifiers, short-acting β2-agonists, oral corticosteroids, other bronchodilators, and no medications were measured on a monthly basis, and the changes were evaluated by using interrupted time series with segmented regression analysis...

PURPOSE OF REVIEW: Although the use of inhaled anticholinergics in obstructive airway disease has been established for several years, the clinical experience using these medications in treating patients with asthma is limited. Only few studies so far have included pediatric patients with asthma, but these studies demonstrate relevant therapeutic effects. This review will explore the pharmacological effects of inhaled anticholinergics, provide an overview about current adult and pediatric asthma studies using tiotropium, and describe future research needs...

BACKGROUND: Long-acting beta2-agonists (LABA) in combination with inhaled corticosteroids (ICS) are increasingly prescribed for children with asthma. OBJECTIVES: To assess the safety and efficacy of adding a LABA to an ICS in children and adolescents with asthma. To determine whether the benefit of LABA was influenced by baseline severity of airway obstruction, the dose of ICS to which it was added or with which it was compared, the type of LABA used, the number of devices used to deliver combination therapy and trial duration...

BACKGROUND: Bronchiectasis is a chronic respiratory disease characterised by abnormal dilatation of the bronchi, and presents typically with a chronic productive cough (or chronic wet cough in children) and recurrent infective exacerbations. It significantly impacts daily activities and quality of life, and can lead to recurrent hospitalisations, severe lung function impairment, respiratory failure and even death. OBJECTIVES: To provide an overview of the efficacy and safety of interventions for adults and children with bronchiectasis from Cochrane reviews...

This multi-center, randomized, double-blind, placebo-controlled, two-way crossover study was designed to characterize the safety, tolerability, pharmacokinetic, and pharmacodynamic profile of single and once-daily repeat doses of vilanterol 25 µg in children aged 5-11 years. Twenty-eight children with persistent asthma received a single inhaled dose of vilanterol 25 µg or placebo via the ELLIPTA™ dry powder inhaler (DPI) on Day 1, followed 7 days later by once-daily treatment for 7 days. Nine (33%) subjects reported adverse events (AEs) with vilanterol 25 µg and 6 (23%) with placebo...

BACKGROUND: When standard doses of inhaled corticosteroids (ICS) fail to control symptoms in children aged >4 years, guidelines recommend the addition of a long-acting β2-agonist (LABA), with other treatment options being available if symptoms persist. AIMS: To determine the proportion of initial 'step-up' episodes where LABAs were prescribed and to describe characteristics of individuals not stepped up with LABA. METHODS: Between 1999 and 2011, initial step-up episodes from ICS monotherapy were identified in children aged 5-12 years with asthma and in receipt of ICS...

BACKGROUND: Because randomized controlled trials of established pediatric asthma therapies are expensive and difficult to perform, observational studies may fill gaps in the evidence base. OBJECTIVES: To compare the effectiveness of representative small-particle inhaled corticosteroid (ICS) with that of standard size-particle ICS for children initiating or stepping up ICS therapy for asthma (analysis 1) and to compare the effectiveness of ICS dose step-up using small-particle ICS with adding long-acting β2-agonist (LABA) to the ICS (analysis 2)...

BACKGROUND: Asthma is the most common chronic medical condition among children and is one of the most common causes of hospitalisation and medical visits. Poorly controlled asthma often leads to preventable exacerbations that require additional medications, hospital stays, or treatment in the emergency department.Long-acting beta2-agonists (LABA) are the preferred add-on treatment for children with asthma whose symptoms are not well controlled on inhaled corticosteroids (ICS). The US Food and Drug Administration has issued a 'black box' warning for LABA in asthma, and now recommends that they be used "for the shortest duration of time required to achieve control of asthma symptoms and discontinued, if possible, once asthma control is achieved"...

OBJECTIVE: To summarize the principal findings pertaining to most effective long-term pharmacologic treatment of childhood asthma. METHODS: Systematic reviews of randomized clinical trials (SRCTs) on pharmacologic chronic treatment in children (1-18 years) with persistent asthma were retrieved through MEDLINE, EMBASE, CINAHL, SCOPUS, and CDSR (up to January2014). RESULTS: One hundred eighty-three SRCTs were searched from databases. Among those, 39 SRCTs were included: two were related to step 1, 24 to step 2, nine to steps 3 and 4, and four to step 5 (according with NAEPP and GINA guidelines)...
