Insights

Asthma does not increase the risk of severe coronavirus disease-2019 (COVID-19). This meta-analysis found no significant association between asthma and severe COVID-19 outcomes.

Area of Science:

  • Pulmonary Medicine
  • Infectious Diseases
  • Epidemiology

Background:

  • Previous studies suggest a correlation between COVID-19 and asthma.
  • Data on asthma as a COVID-19 risk factor and its prevalence in COVID-19 cases remain limited.

Purpose of the Study:

  • To analyze the association between COVID-19 and asthma.
  • To determine if asthma is a risk factor for severe COVID-19.
  • To assess the prevalence of asthma in COVID-19 patients.

Main Methods:

  • Systematic literature search of PubMed, Embase, and Web of Science databases (Jan 1 - Aug 28, 2020).
  • Inclusion of 18 studies reporting epidemiological and clinical features of COVID-19 and asthma prevalence.
  • Meta-analysis of pooled data.

Main Results:

  • The pooled prevalence of asthma in COVID-19 cases was 0.08 (95% CI, 0.06-0.11).
  • Asthma was not found to increase the risk of developing severe COVID-19 (OR 1.04, 95% CI 0.75-1.46).
  • No significant difference in asthma incidence with age was observed in COVID-19 infections.

Conclusions:

  • Asthma is not a significant risk factor for the development of severe COVID-19.
  • The findings contribute to understanding the interplay between respiratory conditions and severe viral infections.

Asthma-I: Introduction01:29

Asthma-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...

Asthma: 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.

Asthma-II: Pathophysiology and Classification01:26

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:

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
