Summary
Near-fatal asthma (NFA) patients in stable conditions are clinically similar to mild-to-moderate asthmatics. Reduced corticosteroid use is a key characteristic of NFA patients.
Area of Science:
- Pulmonology
- Clinical Medicine
- Asthma Research
Background:
- Near-fatal asthma (NFA) involves severe attacks often requiring intensive care.
- NFA has primarily been studied in acute, rather than stable, conditions.
Purpose of the Study:
- To compare clinical, functional, and inflammatory markers of NFA patients with mild-to-severe asthmatics during stable periods.
- To identify distinguishing characteristics of NFA in a stable state.
Main Methods:
- 155 asthma patients were recruited across five European centers.
- Patients were categorized into mild-to-moderate, severe, and NFA groups based on exacerbation history and treatment.
- All participants underwent examination in stable asthma conditions.
Main Results:
- NFA patients reported lower corticosteroid use and adherence compared to other groups.
- Lung function and inflammatory markers in NFA patients resembled those with mild-to-moderate asthma, not severe asthma.
- NFA patients showed similar blood gas levels and atopic status to mild-to-moderate asthmatics.
Conclusions:
- In stable states, NFA patients are indistinguishable from mild-to-moderate asthmatics based on lung function and inflammation.
- NFA patients differ from severe asthmatics in lung function and airway inflammation.
- Reduced prophylactic corticosteroid use is a significant risk factor characterizing NFA patients.

01:23Chronic Obstructive Pulmonary Disease II: Emphysema
Emphysema, a major phenotype of chronic obstructive pulmonary disease (COPD), is characterized by irreversible destruction of alveolar walls and permanent enlargement of distal airspaces. Unlike chronic bronchitis, which primarily affects the airways, emphysema predominantly involves the lung parenchyma, where structural damage leads to airflow limitation.PathophysiologyIt most commonly results from prolonged exposure to cigarette smoke and other toxic gases, particularly cigarette smoke.
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,...
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:

01:20Asthma: 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.

01:28Asthma 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...
01:24Asthma-III: Symptoms and Complications
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:
