Study Details

Prevention Level	Secondary
Author	Lemiere
Study Year	2000
Country	Canada
Molecular Weight of Agent	Both
Category	Various
Agent	N/A
Occupation	Various occupations
Outcome/Diagnosis	Occupational asthma with normal nonspecific bronchial reactivity
Activity Intervention	Removal from exposure (mean: 5.7 years)
Participation Rate	Limitation: no report of participation rate
Intervention Effectiveness	At time of study, all subjects (n=16) had normal lung function with no persistent asthma. Specific bronchial reactivity to HMW agents persisted in most cases. Decline in IgE was greater for subjects with no reaction (n=5) to specific inhalation challenge compared to subjects who did react (n=11). Declines in IgE for both groups were statistically signficant.
