[Bronchial asthma and obesity: common mechanisms]
Klinicheskaia Meditsina
|August 18, 2012
Summary
Obesity and bronchial asthma (BA) share common mechanisms, including inflammation and genetics. Understanding these links can lead to new treatments for both conditions.
Area of Science:
- Pediatrics
- Immunology
- Metabolic Diseases
Context:
- Rising prevalence of bronchial asthma (BA) and obesity in recent decades.
- Mechanisms linking BA and obesity remain incompletely understood.
- Early life factors like diet, gut microbiota, and growth influence both conditions.
Purpose:
- To analyze the association between bronchial asthma and obesity.
- To explore shared underlying mechanisms and distinct phenotypes.
- To identify potential therapeutic targets.
Summary:
- Obesity-associated BA presents with severe symptoms, frequent exacerbations, and poor control, often without cellular inflammation.
- Key mechanisms include comorbidities (GERD, sleep apnea), obesity-related inflammation (cytokines IL-6, TNF-alpha), oxidative stress, and hormonal changes (leptin, adiponectin).
- Common pathways involve genetic predisposition, systemic inflammation, mechanical factors, and comorbidities.
Impact:
- Highlights unique characteristics of obesity-related BA phenotypes.
- Identifies shared etiological factors between BA and obesity.
- Provides a foundation for developing novel, integrated therapeutic strategies for both conditions.

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...
01:26Asthma-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:

01:29Asthma-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...
01:20Asthma: 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.

01:24Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features
Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...
