Using immunologic techniques recently available, we report the evaluation of baker’s asthma due to wheat flour and demonstrate the usefulness of these techniques in occupational asthma. The diagnosis of baker’s asthma was very important in this case, as even a trial of avoidance of work exposure was not possible because of the social and economic factors involved. A commercial wheat extract was obtained and the wheat flour actually used at the work site was extracted. Prick skin testing with each of these extracts resulted in positive wheal and flare responses. Enzyme linked immunosorbent assay and inhibition assays were performed to assess the worker’s antibody response to wheat flour and wheat extracts. Significant specific IgE and IgG levels to the wheat flour and wheat extracts were detected in the worker’s serum. Because of unique psychosocial and educational factors, this worker was unable to change occupations. Even with respiratory protection, she continued to be symptomatic. She is currently controlled on bronohodilators and inhaled steroids.
