Summary
Asthma biomarkers lack specificity across its diverse phenotypes. This study reviews current tissue and lavage markers, comparing them with less invasive options to enhance asthma management.
Area of Science:
- Pulmonary Medicine
- Respiratory Research
- Biomarker Discovery
Background:
- Asthma is a complex respiratory condition with varied clinical presentations (phenotypes).
- Currently, no single biomarker in tissue or bronchoalveolar lavage fluid is definitively specific for diagnosing asthma.
- Understanding cellular and molecular differences is key to personalized asthma care.
Purpose of the Study:
- To review and discuss biomarkers associated with distinct asthma phenotypes, including eosinophilic, neutrophilic, and paucigranulocytic asthma.
- To explore biomarkers related to airway remodeling in asthma.
- To compare the utility of invasive biomarkers (tissue, lavage) with less invasive methods (sputum, serum, exhaled breath) for improved asthma diagnosis and management.
Main Methods:
- Literature review and synthesis of existing research on asthma biomarkers.
- Analysis of studies comparing tissue, bronchoalveolar lavage, sputum, serum, and exhaled breath biomarkers.
- Evaluation of markers related to specific asthma endotypes and airway remodeling.
Main Results:
- Identified various markers linked to eosinophilic, neutrophilic, and paucigranulocytic asthma phenotypes.
- Highlighted biomarkers associated with airway remodeling processes.
- Discussed the potential and limitations of less invasive biomarker measurements compared to traditional methods.
Conclusions:
- No single biomarker is specific for all asthma types, necessitating a phenotype-based approach.
- Less invasive biomarkers show promise for improving asthma diagnosis and treatment monitoring.
- Further research is needed to validate and integrate these biomarkers into clinical practice for better asthma management.

Asthma 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...
Asthma-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:

Asthma 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,...
