Osteopontin levels are elevated in patients with asthma
The Journal of International Medical Research
|October 12, 2011
Summary
Serum osteopontin (OPN) levels are higher in asthma patients, suggesting a role in asthma development. However, OPN levels did not correlate with asthma severity in this study.
Area of Science:
- Immunology
- Allergy Research
- Biochemistry
Background:
- Osteopontin (OPN) is implicated in T cell-mediated immunity.
- The role of OPN in Th2-associated allergic responses, specifically asthma, remains largely unexplored.
Purpose of the Study:
- To investigate elevated serum osteopontin (OPN) levels in asthma patients.
- To determine the correlation between serum OPN concentrations and asthma severity.
Main Methods:
- Cross-sectional case-control study design.
- Serum samples collected from mild, moderate, and severe asthma patients (n=129) and healthy controls (n=41).
- Enzyme-linked immunosorbent assay (ELISA) used to quantify OPN protein concentrations.
Main Results:
- Significantly higher serum OPN levels were observed in all asthma patient groups compared to healthy controls.
- No significant association was found between serum OPN concentration and asthma disease severity.
- These findings indicate a potential role for OPN in asthma pathogenesis.
Conclusions:
- Osteopontin (OPN) may be involved in the development of asthma.
- Further research is warranted to elucidate the specific mechanisms of OPN in various asthma aspects.

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:

01:20Asthma: 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.

Chronic obstructive pulmonary isease (COPD) involves a group of progressive lung disorders characterized by persistent airflow limitation and chronic respiratory symptoms. Asthma-COPD Overlap Syndrome (ACOS), encompassing features of both asthma and Chronic obstructive pulmonary disease (COPD), is a group of progressive lung disorders that includes chronic bronchitis, emphysema, and refractory (non-reversible) asthma. ACOS leads to complex clinical presentations that combine the inflammatory...
