Summary
Asthma exacerbations and severe asthma require better treatment strategies. Current guidelines fall short, necessitating increased awareness and novel approaches for difficult-to-treat asthma patients.
Area of Science:
- Allergy and Clinical Immunology
- Respiratory Medicine
- Immunology
Background:
- Asthma exacerbations and severe asthma are associated with significant morbidity, mortality, and healthcare costs.
- Recurrent exacerbations lead to lung function decline and persistent asthma development in children.
- Current treatment guidelines inadequately address frequent exacerbations and severe, treatment-resistant asthma.
Purpose of the Study:
- To highlight shortcomings in existing asthma treatment guidelines.
- To advocate for increased awareness of asthma exacerbation severity.
- To emphasize the need for novel treatment strategies for severe, treatment-resistant asthma.
Main Methods:
- Review of current evidence on asthma exacerbations and severe asthma.
- Analysis of factors contributing to exacerbations, including viral infections, innate immunity, and allergic mechanisms.
- Discussion of nonadherence, environmental factors, and psychosocial influences in difficult-to-control asthma.
Main Results:
- Strong evidence links asthma exacerbations to viral infections, innate immunity deficiencies, and synergistic effects with allergic mechanisms.
- Medication nonadherence is a common issue in difficult-to-control asthma.
- Modifiable factors like smoking, allergen exposure, and psychosocial issues require clinical prioritization.
Conclusions:
- Current asthma guidelines need revision to better manage frequent exacerbations and severe, treatment-resistant cases.
- Increased awareness of exacerbation seriousness and the need for new treatments is crucial.
- Further research with advanced tools is essential to understand asthma pathophysiology and heterogeneity.

Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:

01:13Asthma III: Clinical Manifestations
49
Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...

01:28Asthma I: Introduction
112
Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

4.7K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
