Asthma exacerbation (AE) usually denotes worsening of asthma symptoms that requires intense management to prevent further deterioration. AE has been reported to correlate with clinical and demographic factors, such as race, gender, and treatment compliance as well as environmental factors, such as viral infection, smoking, and air pollution. In addition, recent observations suggest that there are likely to be genetic factors specific to AE. Understanding genetic factors specific to AE is essential to develop therapy tailored for exacerbation-prone asthma. Here, we summarize the results of studies involving genetic risk factors for AE. To simplify and enhance understanding, we reviewed the studies according to the following categories: hypothesis-driven approaches, hypothesis-free approaches, gene-environment interactions, and pharmacogenetics.

A 78-years-old man was treated for asthma and pansinusitis for >5 years, and mepolizumab was initiated two years previously. Two months after the cessation of mepolizumab treatment, the asthma symptoms worsened and acute progressive muscle weakness and sensory disturbance developed. On day 8 after the onset of weakness and hypoesthesia, the patient presented with complete flaccid tetraplegia and diffuse hypoesthesia of all extremities, without paresthesia or pain, and was admitted to our hospital.

Aim: To assess the effectiveness of intravenous caffeine citrate in paediatric asthma exacerbation unresponsive to beta2-agonists and steroids.
Methods: A 10-year retrospective cohort study was conducted on asthmatic children unresponsive to beta2-agonists and steroids, who were treated with either intravenous caffeine citrate or magnesium sulphate. The study outcomes were changes in the Paediatric Respiratory Assessment Measure (PRAM) score, duration of oxygen therapy and paediatric intensive care unit (PICU) length-of-stay.

Background: Air pollution is associated with poor asthma outcomes in children. However, most studies focus on ambient or indoor monitor pollution levels. Few studies evaluate breathing zone exposures, which may be more consequential for asthma outcomes.
View Article and Find Full Text PDFBackground: In patients with asthma, bronchoconstriction and airway inflammation both contribute to airway narrowing and airflow limitations, which lead to symptoms and exacerbations. Short-acting beta 2-agonist (SABA)-only rescue therapy addresses only bronchoconstriction and is associated with increased morbidity and mortality. Current asthma management guidelines recommend concomitant treatment of symptoms and inflammation with a fast-acting bronchodilator and inhaled corticosteroid (ICS) as rescue therapy for patients 12 years of age.

Introduction: Escalation to single- or multiple-inhaler triple therapy (SITT; MITT) is a recommended option for patients with asthma who remain uncontrolled by medium-dose inhaled corticosteroid/long-acting β-agonist; however, characterization of elderly users of triple therapy is limited. This real-world cohort study describes demographics and clinical characteristics of elderly patients with asthma with and without comorbid chronic obstructive pulmonary disease (COPD) who are new users of triple therapy, and asthma treatment patterns preceding triple therapy initiation.
Methods: This retrospective cohort study used administrative claims data from the Optum Clinformatics Data Mart database.
