|Molecular Weight of Agent||Both|
|Activity Intervention|| Cessation of exposure to the causative agents of high molecular weight (HMW) or low molecular weight (LMW).|
|Participation Rate||73 of 178 patients with occupational asthma and with a positive specific inhalation challenge were included in the study (Participation rate: 40%). 105 patients were excluded from data analysis because of no contact or refused to participate.|
|Intervention Effectiveness||Patients removed from exposure (n=55),
Patients continued to be exposed (n=18),
- with cessation of HMW agent, statistically improved their symptoms of rhinitis, conjunctivitis and the percentage of eosinophils in blood p=0.002, 0.004, 0.018, respectively.
- 47% had clinical improvement and 14% had deterioration on GINA severity sca
- statistically deteriorated their symptoms of rhinitis and conjunctivitis p=0.039 and 0.012, respectivy
- 22% had clinical improvement and 17% had deterioration on GINA severity scale.
