TI  - A Case of Occupational Rhinitis Induced by Maize Pollen Exposure in a Farmer: 
      Detection of IgE-Binding Components.

AB  - Corn is a major staple food, along with rice and wheat, in many parts of the 
      world. There are several reports of hypersensitivity to maize pollen. However, 
      cases of occupational allergic rhinitis induced by inhalation of maize pollen are 
      very rare. We herein report the case of a 67-year-old male with occupational 
      rhinitis caused by occupational exposure to maize pollen in a cornfield. He 
      showed positive responses to maize pollen, as well as grass pollens, in skin 
      prick tests. A high level of serum immunoglobulin E (IgE) specific to maize 
      pollen extracts was detected by an enzyme-linked immunosorbent assay (ELISA). 
      Laboratory tests showed a high serum level of total IgE (724 kU/L) and a high 
      level of IgE specific to maize pollen (8.32 kU/L) using the Immuno-CAP system. 
      Occupational rhinitis was confirmed by a nasal provocation test with maize pollen 
      extracts. IgE ELISA inhibition tests showed antibody cross-reactivity between 
      maize pollen and grass pollen extracts. IgE immunoblotting using maize pollen 
      extracts demonstrated a 27 kDa IgE-binding component. These findings suggest that 
      maize pollen can induce IgE-mediated occupational rhinitis in exposed workers.
