Occupational Allergic Disorders Diagnosis and Treatment
What are occupational allergy disorders?
Occupational allergy refers to those disorders or conditions that are caused by exposure to allergenic substances in the work environment. The allergic diseases that may be contracted as a consequence of exposure to sensitizing agents in the workplace are rhinitis, conjunctivitis, asthma, hypersensitivity pneumonitis and skin diseases, such as contact urticaria and contact dermatitis. Different immunologic mechanisms may underlie these disorders. Occupational rhinitis and occupational asthma (OA) are usually due to an allergic response to high or low molecular weight antigens, either through the interaction with specific IgE antibodies or by other immune mechanisms. These allergic events lead to chronic and acute airway inflammation. Less commonly, OA can result from high level irritant exposures at work.
