Prevention Level	Secondary
Author	Park
Study Year	2007
Country	Korea
Molecular Weight of Agent	LMW
Category	Other Chemicals
Agent	Reactive dye
Occupation	Not specified
Outcome/Diagnosis	Occupational asthma
Activity Intervention	Removal from exposure to reactive dye. First and second follow-up examinations were conducted at 4.3(2.3) and 13.7(2.3) years (means (SD)) after the initial examinations.
Participation Rate	Limitation: no report of participation rate. There were a total of 11 patients with reactive dye induced occupational asthma enrolled in this study.
Intervention Effectiveness	1. There is no significant improvement after patients were completely removed from exposure to RD over a 10-year period. 2. Reduced lung function did not recover after the cessation from exposure and proper pharmacological treatment. 3. Asthma severity and non-specific airway hyper-responsiveness to methacholine also did not improve over a period of 10 years, although skin reactivity to reactive dye almost disappeared over this time-frame.
