Summary
Asthma management during pregnancy showed slightly lower exacerbation rates but variable control. Close monitoring is recommended, especially for women with pre-existing poor asthma control.
Area of Science:
- Reproductive medicine
- Pulmonology
- Public health
Background:
- Asthma affects a significant number of pregnancies.
- Limited research exists on asthma management changes during pregnancy.
- Understanding these changes is crucial for maternal and fetal health.
Purpose of the Study:
- To determine asthma prevalence in pregnant women.
- To identify changes in asthma treatment and exacerbation rates during pregnancy.
- To control for seasonal variations in exacerbation rates.
Main Methods:
- Utilized UK General Practice Research Database (2000-2008).
- Identified asthma medications and treatment steps (British Thoracic Society).
- Analyzed exacerbations and treatment changes, stratified by trimester and intensity, controlling for seasonality.
Main Results:
- Prevalence of treated asthma in pregnancies was 8.3%.
- 68.4% received short-acting β2-agonists, 41.2% inhaled corticosteroids.
- Exacerbation rates were lower during pregnancy (4.8%) vs. prior year (5.9%).
- Treatment step increased in 45.0% of pregnancies; poor inhaled corticosteroid persistence was common.
Conclusions:
- Pregnancy-associated asthma exacerbation rates were slightly reduced.
- Asthma control during pregnancy appears variable.
- Close monitoring is advised, particularly for those with pre-pregnancy poor control.

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.

01:25Antiasthma 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...

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...
01:23Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics
Respiratory symptoms, such as congestion and cough, commonly accompany respiratory tract conditions. Various medications, such as antitussives, expectorants, and mucolytics, play crucial roles in providing relief.
Antitussives include codeine, dextromethorphan (Robitussin), and benzonatate (Tessalon). Codeine and dextromethorphan exert their effects centrally by suppressing the cough reflex center in the medulla. Benzonatate operates peripherally within the respiratory tract by anesthetizing...
