Wheezing in Preschool Children
Introduction
Clinical Scenarios
Pathophysiology of Wheezing
∆P = KV
V = darrSvuarr
Re = 2rvdn gt 2000
∆P = KV2
Clinical Case 1
12 mo with 3 episodes of cough over the last year
Association with viral respiratory infections
Recurrent Viral-Associated Wheezing
Bisgaard et al AJRCCM 2005171315
Clinical Case 2
6 mo - cough for 2 months (uarr at night)ldquoCongestedrdquo chestClear nasal drainageMaternal asthma
Wheezing in Preschool Children
Wheezing and
Anti-inflammatory Treatment
Anti-inflammatory Medications for Wheezing to Preschool Children Why
Ameliorate symptoms associated with lower airway obstruction
Prevent recurrences and improve quality of life
Prevent deficits in lung function growth
To maximize efficacy of anti-inflammatory medications and to minimize side effects we need to know
Which preschool children will develop asthma
Which subjects are at risk for deficits in growth of lung function
Which wheezing phenotypes are responsive to anti-inflammatory medications
What are the possible side effects of ICS in relation to duration of treatment
Definition of Bronchial AsthmaNHLBI-Expert Panel Report 2 (1997)
Recurrent episodes of reversible lower airway obstruction (withoutwithout treatment)
Inflammation of the lower airways (eosinophils mastocytes lymphocytes)
Bronchial hyperresponsiveness

Anti-inflammatory Medications for Wheezing to Preschool Children Why
Ameliorate symptoms associated with lower airway obstruction
Prevent recurrences and improve quality of life
Prevent deficits in lung function growth
To maximize efficacy of anti-inflammatory medications and to minimize side effects we need to know
Which preschool children will develop asthma
Which subjects are at risk for deficits in growth of lung function
Which wheezing phenotypes are responsive to anti-inflammatory medications
What are the possible side effects of ICS in relation to duration of treatment
