This includes ICS-containing medications (alone or in combination), and add-on therapy including biologic therapy for severe asthma. Stopping ICS often leads to potentially dangerous worsening of asthma. For a small proportion of patients with severe asthma, long-ter guidelines on severe asthma in adults and school age children were published in 2014 (1). Severe asthma was defined as follows: 'When the diagnosis of asthma is confirmed and comorbidities addressed, severe asthma is defined as asthma that requires treatment with high dose inhaled corticosteroids plus a second controlle Continue the treatment with salbutamol for 24 to 48 hours (2 to 4 puffs every 4 hours) and prednisolone PO (1 to 2 mg/kg once daily) to complete 3 days of treatment. Reassess after 10 days: consider long-term treatment if the asthma attacks have been occurring for several months

In general, primary treatment (i.e., administration of oxygen, inhaled β 2 -agonists, and systemic corticosteroids) is the same for all asthma exacerbations, but the dose and frequency of administration, along with the frequency of patient monitoring, differ depending on the severity of the exacerbation (Figure 1 and Table 3) When a diagnosis of asthma is confirmed and comorbidities addressed, severe asthma is defined as asthma that requires treatment with high dose inhaled corticosteroids [] plus a second controller (and/or systemic corticosteroids) to prevent it from becoming 'uncontrolled' or which remains 'uncontrolled' despite this therapy

Severe asthma is a heterogeneous condition consisting of phenotypes such as eosinophilic asthma. Specific recommendations on the use of sputum eosinophil count and exhaled nitric oxide to guide therapy, as well as treatment with anti-IgE antibody, methotrexate, macrolide antibiotics, antifungal agents and bronchial thermoplasty are provided GENERAL TREATMENT PRINCIPLES Treatment of severe asthma frequently requires a multidisciplinary approach to address patient education needs, remediate irritant and allergic triggers, treat comorbidities, and design an optimal medication regimen Quality asthma care involves not only initial diagnosis and treatment to achieve asthma control, but also long-term regular follow-up care to maintain control.Asthma control focuses on two domains: 1) reducing impairment- the frequency and intensity of symptoms and functional limitations currently or recently experienced by a patient; and 2) reducing risk-the likelihood of future asthma attacks, progressive decline in lung function or lung growth, or medication side effects Preventive Treatment Consider preventive treatment if there are interval or persistent symptoms (more than one disturbed night per week, difficulty participating in physical activities, or bronchodilator use on more than one day per week). There is a limited role in children with viral induced asthma, even with frequent exacerbation Asthma has a national prevalence of 10.8% and affects 3.8 million Canadians over the age of 1 year.1 The last Canadian Thoracic Society (CTS) asthma pos-ition statement focused on the treatment and management of those with severe asthma,2 which is estimated to affect 5-10% of those with asthma.

  1. Background: COVID-19 vaccination has been recommended for severe asthmatics. We aimed to evaluate the safety, tolerability, and impact on disease control and patient's quality of life of the mRNA SARS-CoV-2/COVID-19 vaccine in severe asthma patients regarding biologic treatment. Methods: Severe asthmatic patients regularly managed by two big allergy and respiratory referral centers were.

In recent years, new treatments have become available, and different asthma.
  5. For moderate and severe acute asthma attacks, immediate treatment with oxygen via a tight-fitting face mask or nasal prongs should be given to achieve normal SpO 2 saturations of 94-98%. Trial an inhaled short-acting beta 2 agonist and if response is poor, combine nebulised ipratropium bromide to each nebulised beta 2 agonist dose

Early treatment of asthma exacerbations is the best strategy for management. Important elements of early treatment at the patient's home include a written asthma action plan; recognition of early signs and symptoms of worsening; appropriate intensification of therapy by increasing short-acting β-agonists and, in some cases, adding a short course of oral corticosteroids; removal, or withdrawal.
