초록
Occupational allergic rhinitis caused by rabbit fur has been reported in Korea. However, occupational asthma due to rabbit fur has not yet reported in Korea. We report a suspected case of allergic asthma caused by rabbit fur on occupational exposure. A 35-year-old male developed dyspnea, chest discomfort related to rabbit fur. He has been worked for a spinning factory. He presented with a history of allergic rhinitis and asthma. Peripheral blood eosinophil count was 690/mm3. Bronchodilator response was positive, the results of skin prick test were positive for house dust mite, cockroach and rabbit fur. The level of specific IgE for rabbit fur was 8.39 KU/L. The methacholine challenge test was positive (PC20 1.96 mg/mL). These findings suggest that the rabbit fur could induce occupational asthma. We could not perform bronchoprovacation test with rabbit fur due to patient’s refusal. He is in a well controlled state with the use of a combination of inhaled corticosteroid and long acting β2 agonist after the avoidance of rabbit fur.
