[Occupational airway sensitization due to subtilisin]

Since the 1960s an increasing number of occupational allergies against natural, and against modified recombinant enzymes were observed. Subtilisin, a frequently used enzyme often has been shown to cause airway sensitization. The present evaluation of clinical literature data confirms the sensitization potential of subtilisin. Several cases of specific airway hyperresponsiveness caused by subtilisin are verified by a number of studies. As symptoms, results of skin prick tests, detection of specific IgE-antibodies and results of specific bronchoprovocation tests are consistent, an immunologic mechanism is confirmed.
