Lecture 10 (pulm)-Exam 5 Flashcards
Pathophysio
Asthma:
* Allergen from an environmental trigger picked up by what?
* What do the cells present them to?
* What is released after that?
- Allergen from an environmental trigger picked up by dendritic cells
- Dendritic cells present them to TH2 cells
- TH2 cells release cytokines causing inflammation-> Cytokines (IL4 and IL5)
Pathophysio
What does IL4 and IL5 cause?
IL4
* Stimulates B-cells to produce IgE which binds to Fc€RI receptors on mast cells
* Mast cells use phospholipase A2 to produce arachidonic acid (AA)
* AA metabolized by:
* COX to prostaglandins
* 5-LOX to leukotrienes
IL5
* Activates eosinophils
* Promotes immune response by releasing more cytokines and leukotrienes
Asthma
* Airway obstruction caused by what? (irreversible or not?)
* Part of what triad?
ASTHMA – GOALS OF TREATMENT
* Reduce impairment: Prevent what, require what, normal what?
- Prevent chronic symptoms (if no txt: damage)
- Require minimal use of reliever (ex: SABA)
- Normal or near normal lung function and activity levels
Asthma: goals of treatment:
* Reduce risk: Prevent what? (2) Minimize what? (2)
- Prevent exacerbations
- Minimize need for emergency care and hospitalization
- Prevent decreased lung function
- Minimize pharmacotherapy adverse effects
What are the Nonpharmacologic treatment of asthma? (4)

- Weight loss
- Breathing exercise programs->Adults
Medication definitions
* What is a reliever?
