Correlation of Serial IgE and Spirometry in a Case of Baker's Asthma

Occupational and baker’s asthma are well-understood forms of airway restriction and hypersensitivity. Serum immunoglobulin E (IgE) monitoring is often recommended to aid in the diagnosis of baker’s asthma but is rarely used to monitor temporal changes in IgE levels. Combined with the use of serial spirometry, this case aims to provide evidence that serial IgE testing can be used to show that removal from the antigen source leads to decreased IgE levels, improved spirometry results, and coincidence improved clinical symptoms of patients suffering from Occupational asthma (OA).
