Summary
The causes of severe asthma are unclear, leading to significant healthcare costs. Further research into genetic, environmental, and physiological factors is needed for better treatment strategies.
Area of Science:
- Pulmonology and Respiratory Medicine
- Clinical Immunology
Background:
- Severe asthma represents a significant burden, disproportionately consuming healthcare resources.
- The underlying mechanisms driving severe asthma development remain poorly understood.
- Disease onset can be gradual or rapid, highlighting complex etiological pathways.
Purpose of the Study:
- To elucidate the poorly understood mechanisms contributing to severe asthma development.
- To identify key genetic and environmental factors implicated in severe disease.
- To characterize the physiological and pathological heterogeneity in severe asthma.
Main Methods:
- Review of existing literature on severe asthma pathophysiology.
- Analysis of physiological parameters such as air trapping and airway collapsibility.
- Examination of pathological findings including inflammation and airway remodeling.
Main Results:
- Severe asthma exhibits heterogeneous pathologies, including eosinophilic inflammation and structural remodeling.
- Physiological hallmarks include air trapping and airway collapsibility.
- The precise genetic and environmental triggers remain largely unidentified.
Conclusions:
- Understanding the diverse mechanisms of severe asthma is critical for improving patient outcomes.
- Current treatment strategies are limited by the incomplete knowledge of disease development.
- Further research is essential to develop targeted and effective therapies for severe asthma.

01:20Asthma: Pathogenesis and Management
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.

01:29Asthma-I: Introduction
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...
01:26Asthma-II: Pathophysiology and Classification
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:

01:28Asthma I: Introduction
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...
01:13Asthma III: Clinical Manifestations
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,...
