BACKGROUND/OBJECTIVE: To integrate new evidence into the Canadian Asthma Management Continuum diagram, encompassing both pediatric and adult asthma.METHODS: The Canadian Thoracic Society Asthma Committee members, comprised of experts in pediatric and adult respirology, allergy and immunology, emergency medicine, general pediatrics, family medicine, pharmacoepidemiology and evidence-based medicine, updated the continuum diagram, based primarily on the 2008 Global Initiative for Asthma guidelines, and performed a focused review of literature pertaining to key aspects of asthma diagnosis and management in children six years of age and over, and adults.RESULTS: In patients six years of age and over, management of asthma begins with establishing an accurate diagnosis, typically by supplementing medical history with objective measures of lung function. All patients and caregivers should receive self-management education, including a written action plan. Inhaled corticosteroids (ICS) remain the first-line controller therapy for all ages. When asthma is not controlled with a low dose of ICS, the literature supports the addition of long-acting beta2-agonists in adults, while the preferred approach in children is to increase the dose of ICS. Leukotriene receptor antagonists are acceptable as second-line monotherapy and as an alternative add-on therapy in both age groups. Anti-immunoglobulin E therapy may be of benefit in adults, and in children 12 years of age and over with difficult to control allergic asthma, despite high-dose ICS and at least one other controller.CONCLUSIONS: The foundation of asthma management is establishing an accurate diagnosis based on objective measures (eg, spirometry) in individuals six years of age and over. Emphasis is placed on the similarities and differences between pediatric and adult asthma management approaches to achieve asthma control.

AbstractSevere therapy-resistant asthma has been defined as “asthma which requires treatment with high dose inhaled corticosteroids (ICSs) plus a second controller (and/or systemic corticosteroids) to prevent it from becoming ‘uncontrolled’ or which remains ‘uncontrolled’ despite this therapy”. Patients who usually present with ‘difficult-to-treat asthma’ should first be assessed to determine whether he/she has asthma with the exclusion of other diagnoses and if so, whether the asthma can be classified as severe therapy-resistant. This necessitates an assessment of adherence to medications, confounding factors, and comorbidities. Increasingly, management of severe therapy-resistant asthma will be helped by the determination of phenotypes to optimize responses to existing and new therapies. Severe asthma patients are usually on a combination of high dose ICS and long-acting β-agonist (LABA) and, in addition, are often on a maintenance dose of oral corticosteroids. Phenotyping can be informed by measuring blood eosinophil counts and the level of nitric oxide in exhaled breath, and the use of sputum granulocytic counts. Severe allergic asthma and severe eosinophilic asthma are two defined phenotypes for which there are efficacious targeted biologic therapies currently available, namely anti-immunoglobulin E (IgE) and anti-interleukin (IL)-5 antibodies, respectively. Further progress will be realized with the definition of noneosinophilic or non-T2 phenotypes. It will be important for patients with severe asthma to be ultimately investigated and managed in specialized severe asthma centers.

Consensus Report

BACKGROUND: Several sets of Canadian guidelines for the diagnosis and management of asthma have been published over the past 15 years. Since the last revision of the 1999 Canadian Asthma Consensus Report, important new studies have highlighted the need to incorporate new information into the asthma guidelines.OBJECTIVES: To review the literature on adult asthma management published between January 2000 and June 2003; to evaluate the influence of the new evidence on the recommendations made in the 1999 Canadian Asthma Consensus Guidelines and its 2001 update; and to report new recommendations on adult asthma management.METHODS: Three specific topics for which new evidence affected the previous recommendations were selected for review: initial treatment of asthma, add-on therapies in the treatment of asthma and asthma education. The resultant reviews were discussed in June 2003 at a meeting under the auspices of the Canadian Thoracic Society, and recommendations for adult asthma management were reviewed.RESULTS: The present report emphasises the importance of the early introduction of inhaled corticosteroids in symptomatic patients with mild asthma; stresses the benefit of adding additional therapy, preferably long-acting beta2-agonists, to patients incompletely controlled on low doses of inhaled corticosteroids; and documents the essential role of asthma education.CONCLUSION: The present report generally supports many of the previous recommendations published in the 1999 Canadian Asthma Consensus Report and provides higher levels of evidence for a number of those recommendations.

BACKGROUND: A novel anti-immunoglobulin E (anti-IgE) therapy for asthma, omalizumab, has been approved for use in Canada.OBJECTIVE: To review the basic and clinical data for omalizumab, and to examine its possible role for asthma management in Canada.METHODS: A literature search from 1960 to 2006 was conducted in MEDLINE to identify studies of omalizumab. In addition, abstracts from recent respiratory and allergy scientific meetings were sought, and any unpublished data were requested from the manufacturer. A consensus panel of respiratory and allergy specialists reviewed and summarized the data, and derived a set of recommendations for omalizumab use.RESULTS: Omalizumab is a humanized monoclonal antibody designed to bind to the C epsilon 3 domain of the IgE molecule, forming soluble immune complexes that are cleared by the reticuloendothelial system. Subcutaneous injections, given at two- or fourweek intervals at the recommended dose, result in a rapid decrease in free circulating IgE levels. In two phase III clinical trials of 1405 adult and adolescent patients with moderate to severe asthma maintained on moderate doses of inhaled corticosteroids (ICS), omalizumab reduced exacerbation rates compared with placebo, and was associated with improved symptoms and a greater corticosteroid-sparing effect. In a trial of 419 patients with severe disease that was uncontrolled despite the use of high-dose ICS and concurrent long-acting beta2-agonists, severe exacerbations were 50% less frequent in omalizumabtreated patients than in control subjects. Retrospective analyses have identified the characteristics of patients most likely to respond to omalizumab treatment.RECOMMENDATIONS: Omalizumab may be considered as a potential adjunctive therapy in atopic patients with severe asthma uncontrolled by conventional therapy with optimal doses of ICS and appropriate adjunctive therapy (eg, long-acting beta2-agonists). Typically, patients are identified by the need for frequent short course or continuous oral corticosteroids. Therapy should be initiated only after review by a specialist to confirm the diagnosis and that conventional therapy is optimal.

Asthma Mortality

AbstractThe prevalence of asthma is still high in many countries. However, the asthma mortality rate has been significantly decreased after the epidemic of asthma death in the 1970s. The epidemic was occurred in New Zealand and was associated with the use of high-dose inhaled fenoterol at that time. The increased use of inhaled corticosteroids (ICS) in asthma management is proposed as the key factor in the declining trend of asthma mortality rate. The risk factors of asthma-related deaths included history of near-fatal asthma requiring intubation and mechanical ventilation, hospitalisation or emergency care visit for asthma in the past year, currently using or having recently stopped using oral corticosteroids, not currently using ICS, overuse of short-acting b2-agonists, history of psychiatric disease or psychosocial problems, poor adherence with asthma medications and/or poor adherence with (or lack of) a written asthma action plan, food allergy in a patient with asthma, and air pollution.

Asthma is a common comorbidity during pregnancy and its prevalence is increasing in the community. Exacerbations are a major clinical problem during pregnancy with up to 45% of women needing to seek medical help, resulting in poor outcomes for mothers and their babies, including low birth weight and preterm delivery. The goals of effective asthma management in pregnancy are to maintain the best possible asthma control and prevent exacerbations. This is achieved by aiming to prevent day- and night-time symptoms, and maintain lung function and normal activity. In addition, maintaining fetal oxygenation is an important consideration in pregnancy. Guidelines recommend providing asthma advice and review prior to conception, and managing asthma actively during pregnancy, with regular 4-weekly review, provision of a written action plan, use of preventer medications as indicated for other adults with asthma, and management of comorbid conditions such as rhinitis.Improvements have been made in recent years in emergency department management of asthma in pregnancy, and multidisciplinary approaches are being proposed to optimise both asthma outcomes and perinatal outcomes. One strategy that has demonstrated success in reducing exacerbations in pregnancy is treatment adjustment using a marker of eosinophilic lung inflammation, the exhaled nitric oxide fraction (FeNO). The use of an algorithm that adjusted inhaled corticosteroids (ICS) according toFeNOand added long-acting β-agonists when symptoms remained uncontrolled resulted in fewer exacerbations, more women on ICS but at lower mean doses, and improved infant respiratory health at 12 months of age. Further evidence is needed to determine whether this strategy can also improve perinatal outcomes and be successfully translated into clinical practice.Key pointsAsthma is the most common chronic disease to affect pregnant women.Exacerbations occur in up to 45% of pregnant women with asthma.Asthma should be managed during pregnancy as for other adults.Treatment adjustment using a marker of airway inflammation reduces the exacerbation rate in pregnancy.Educational aimsTo identify the goals of and steps associated with effective asthma management in pregnancy.To understand the maternal and perinatal risks associated with asthma during pregnancy.To describe a management strategy that has been shown to reduce exacerbations in pregnant women with asthma.

Objective: To evaluate data on anti-immunoglobulin E (anti-IgE) therapy for asthma. Data Sources: Information was selected from PubMed from 1989 to May 2007 using the search term omalizumab and included randomized, controlled trials. These studies evaluated asthma treatment with omalizumab and focused on its efficacy, tolerability, and cost-effectiveness in this population. Study Selection and Data Extraction: All randomized clinical trials were reviewed (23 were identified and 19 were included; 3 were not relevant and 1 contained duplicative data). Other articles using the search words anti-IgE therapy and cost-effectiveness were evaluated; relevant information was extracted. Data Synthesis: IgE-dependent mechanisms play an important role in the development and maintenance of airway inflammation in asthma. Omalizumab is a subcutaneously administered monoclonal anti-IgE antibody that reduces unbound IgE concentrations and promotes down-regulation of IgE receptors. Results from clinical trials in adults, adolescents, and children with poorly controlled IgE-mediated asthma have shown that omalizumab improves symptom control and allows patients to be managed with lower doses of inhaled corticosteroids (ICS). It has been well tolerated in clinical trials lasting as long as 52 weeks, but injection-site reactions are common (45% in omalizumab group vs 43% in placebo group) and anaphylaxis has occurred in 0.2% of patients. A consensus expert panel has recommended that omalizumab should be considered for patients 12 years of age or older with allergic asthma who are inadequately controlled on guideline-based therapy and require maintenance therapy with systemic corticosteroids or high-dose ICSs, or who have poor adherence to ICS therapy. Conclusions: Anti-IgE therapy provides an effective and generally safe approach to the treatment of patients with IgE-mediated asthma who are not adequately controlled by conventional guideline-based medications. However, the potential benefit must be weighed against the cost and inconvenience of this new therapy.

Background: Dupilumab, an anti-IL-4 receptor a mAb, inhibits IL-4/IL-13 signaling, key drivers of type 2/TH2 immune diseases (eg, atopic/allergic disease). In a pivotal, phase 2b study (NCT01854047), dupilumab reduced severe exacerbations, improved lung function and quality of life, and was generally well tolerated in patients with uncontrolled persistent asthma despite using medium-to-high-dose inhaled corticosteroids plus long-acting b2-agonists. Objective: To examine dupilumabʼs effect on the 22-item Sino-Nasal Outcome Test (SNOT-22) total score and its allergic rhinitis (AR)-associated items in asthma patients with comorbid perennial allergic rhinitis (PAR). Methods: A post hoc analysis reporting data from the phase 2b study for the 200 and 300 mg every 2 week (q2w) doses under investigation in phase 3 (NCT02414854) was carried out. PAR was defined at study entry as a specific response to typical perennial antigens (IgE >0.35 Ku/L). Results: Overall, 241 (61%) patients had PAR. In asthma patients with PAR, dupilumab 300 mg q2w versus placebo significantly improved SNOT-22 total score (least squares mean difference, 25.98; 95% CI, 210.45 to 21.51; P 5.009) and all 4 AR-associated symptoms evaluated (nasal blockage, 20.60; 95% CI, 20.96 to 20.25; runny nose, 20.67; 95% CI, 21.04 to 20.31; sneezing, 20.55; 95% CI, 20.89 to 20.21; postnasal discharge, 20.49; 95% CI, 20.83 to 20.16; all P < .01). Dupilumab 200 mg q2w demonstrated numerical, but not statistically significant, decreases in SNOT-22 total score (21.82; 95% CI, 26.46 to 2.83; P 5 .443 vs placebo) and in each ARassociated symptom. In patients without PAR, no differences were observed for these measures versus placebo. Conclusions: Dupilumab 300 mg q2w significantly improved AR-associated nasal symptoms in patients with uncontrolled persistent asthma and comorbid PAR.

Tract Infections

Recurrent wheezing is common in young infants and toddlers, with 50% of all children having at least one wheezing episode in the first 6 years of life. Initial wheezing episodes in young children often are linked to respiratory infections due to viral pathogens, such as respiratory syncytial virus, human rhinovirus, human metapneumovirus, and influenza virus. Bacterial colonization of the neonatal airway also may be significant in the late development of recurrent wheeze and asthma. Wheezing in young children can be classified into specific phenotypes based on the onset and persistence of wheezing. Although some children will only wheeze transiently in early childhood, persistent wheezing is often classified as immunoglobulin E (IgE) associated and/or atopic or nonatopic. By using a modified asthma predictive index, future development of asthma can be interpreted, especially in high-risk populations. It is recommended to follow National Asthma Education and Prevention Program (NAEPP) guidelines for initiation of treatment; however, asthma management of young children often requires tailored regimens. Inhaled corticosteroids used as a daily controller medication have been shown to aid symptoms and exacerbation control; however, these do not change the natural course of the disease or progression to asthma. Although randomized double-blind studies in preschoolers investigated a role of macrolide antibiotics in early infection as well as high-dose inhaled corticosteroids during severe lower respiratory tract infections, more research is needed in this field to understand mechanisms of asthma development and optimal treatment in this young age group.
