• Long
term studies suggest many children become asymptomatic by adolescence (M>F).
• May
return in some particularly in those with severe disease.
• Severity
does not vary in a given patient; those with mild asthma rarely progress to
more severe disease, whereas those with severe disease usually have severe
disease at the onset.
• Deaths
from asthma have declined over the years mostly attributed to widespread use of
inhaled corticosteroids.
• Risk
factors for asthma deaths :
> poorly controlled disease with frequent use of bronchodilator inhalers.
> lack of corticosteroid therapy.
> previous admission with near fatal asthma.
