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 I: Introduction01:28

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: Pathogenesis and Management01:20

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-III: Symptoms and Complications01:24

Asthma-III: Symptoms and Complications

Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:

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:
Upper Respiratory Drugs: Antitussives, Expectorants, and Mucolytics01:23

Upper 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...

Area of Science:

  • Obstetrics and Gynecology
  • Pulmonology
  • Perinatal Medicine

Background:

  • Asthma is a common medical condition complicating pregnancy.
  • Approximately one-third of pregnant women experience worsening asthma, one-third improve, and one-third remain unchanged.

Purpose of the Study:

  • To emphasize the importance of optimal asthma control during pregnancy for maternal and fetal well-being.
  • To highlight key management strategies and risks associated with poorly controlled asthma.

Main Methods:

  • Review of current understanding and guidelines for asthma management in pregnancy.
  • Identification of preferred controller and add-on therapies.
  • Analysis of asthma exacerbation triggers and associated risks.

Main Results:

  • Optimal asthma control is essential for maternal health and fetal development.
  • Key management strategies include preconception care, trigger avoidance (especially smoking), and adherence to controller medications.
  • Inhaled corticosteroids (ICS), particularly budesonide, are the preferred controller therapy, with long-acting beta-agonists (LABA) as add-on therapy.
  • Viral infections and nonadherence to ICS are major triggers for exacerbations.
  • Acute exacerbations in the first trimester increase the risk of congenital malformations.
  • Poorly controlled asthma is linked to low birth weight, preeclampsia, and preterm birth.

Conclusions:

  • Effective asthma management during pregnancy requires a proactive approach, starting before conception.
  • Patient education on medication adherence, trigger avoidance, and prompt exacerbation treatment is vital.
  • Appropriate pharmacotherapy, prioritizing inhaled corticosteroids, ensures better outcomes for both mother and child.
