Asthma: Pathogenesis and Management

449
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.

Asthma-I: Introduction

2.7K
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...

Area of Science:

  • Pulmonology and Virology
  • Immunology of Respiratory Infections

Background:

  • Asthma exacerbations are frequently triggered by viral infections.
  • Individuals with asthma exhibit heightened susceptibility to viruses, leading to more severe respiratory symptoms due to impaired immune responses.
  • Rhinovirus (RV) is the most common viral culprit in asthma exacerbations for both children and adults.

Purpose of the Study:

  • To review epidemiological, clinical, and mechanistic links between viral infections and asthma exacerbations.
  • To examine the impact of SARS-CoV-2 and COVID-19 on asthma patients.
  • To identify current and future therapeutic and prevention targets for virus-associated asthma exacerbations.

Main Methods:

  • Literature review of epidemiological and clinical studies.
  • Analysis of mechanistic studies on virus-host interactions in asthma.
  • Inclusion of recent evidence on SARS-CoV-2 and COVID-19 in asthma.

Main Results:

  • Viral infections are a primary cause of asthma exacerbations.
  • Specific viruses like rhinovirus are frequently implicated.
  • Emerging evidence on SARS-CoV-2/COVID-19 in asthma patients is considered.

Conclusions:

  • Early intervention against viral infections can significantly decrease asthma exacerbation rates.
  • Vaccine development offers promising strategies for prevention and management.
  • Future research should focus on broad-spectrum vaccines to enhance asthma patient quality of life and reduce healthcare costs.
