Flashcards

Environmental Control for Asthma

Identifying and avoiding triggers in your environment like dust mites, pet dander, cigarette smoke, and work irritants.

Allergen Immunotherapy for Asthma

A treatment that desensitizes your immune system to allergens, reducing asthma symptoms over time.

Monoclonal Antibody Therapy for Asthma

Medications that target inflammatory pathways in asthma, used for moderate to severe cases that don't respond to inhaled corticosteroids.

Bronchial Thermoplasty for Asthma

A minimally invasive procedure for severe asthma that uses heat to reduce muscle thickening in the airways and improve airflow.

Beta2-adrenergic agonists

Short-acting bronchodilators that quickly relax airway muscles, relieving bronchospasm and improving airflow during asthma attacks. Used for immediate relief.

Anticholinergic agents

Short-acting bronchodilators that work by blocking a different pathway than beta2-agonists to relax airway muscles and improve airflow. May be used alone or with beta2-agonists for quick relief.

Beta2-Agonist/Corticosteroid Combinations

Combine a long-acting beta2-agonist with an inhaled corticosteroid. This provides both quick relief and long-term control of inflammation.

Study Notes

Asthma

  • Pathophysiology:
    • Airway hyper-responsiveness: Airways become overly sensitive to triggers, causing constriction.
    • Inflammation: Immune cells (eosinophils, mast cells, T-lymphocytes) cause inflammation, damaging airways and producing mucus.
    • Airway remodeling: Chronic inflammation leads to permanent narrowing and thickening of the airways.

Etiology

  • Complex interplay of genetics and environmental factors: The exact cause is unknown, but genetics (family history) and environmental exposures (allergens, irritants, viral infections, occupational exposures, socioeconomic factors) play a role.

Epidemiology

  • Global health problem: A significant global concern affecting millions.
  • Variations in prevalence: Rates vary geographically, higher in developed countries and urban areas, with low-income populations also affected by socioeconomic factors.

Understanding Factors

  • Identifying at-risk populations: Understanding these factors helps in identification of at-risk groups and development of preventive strategies.

Prognosis

  • Lifelong condition, but manageable: Asthma is a chronic condition. Proper management and treatment can allow for a fulfilling life.
  • Early diagnosis and treatment crucial: Early diagnosis and treatment can help prevent complications like lung decline and hospitalization.
  • Importance of good asthma control: Well-controlled asthma improves quality of life and life expectancy.
