Early diagnosis of Allergology is key to the prognosis of the disease and the health and socio-economic consequences that can represent for the patient.

Baker Asthma is a respiratory disease of immune occupational cause, because it is caused by prolonged exposure to allergens.


Allergens that influence Asma Baker

  • Allergens from cereal grain: the albumins and globulins present in wheat flour and rye are the main allergens involved in Asma Baker, most affectations is given by wheat flour. Although also been Occupational asthma Baker patients affected by flours that are not from cereal, such as soy.
  • Bakery additives: there is also prolonged exposure to enzymes that are used as additives in many products, such as amylase, cellulase, hemicellulase, xylanase and glucoamylase.
  • natural pollutants: the most common are mushrooms, Weevil and certain mites. Dust mites are the main culprits also the "Asthma Barn" habitual workers in mills, silos and farmers.

In the case of baker's asthma, try to control the concentration of flour in the working environment below the level that causes symptoms to individuals already sensitized, which is 10 ng / m3.

Respiratory protective measures: Some preventive measures for people sensitive to flour is to use a protective mask, even with a high efficiency filter to avoid breathing the flour particles present in the environment.

In the Ama Baker immunotherapy is effective in patients sensitized to wheat flour or natural contaminants, already have symptoms. Studies have shown that after 20 months of immunotherapy treatment against wheat flour, has been a significant decrease in bronchial hyperresponsiveness and skin sensitivity of patients.
  • Monoclonal Antibodies: This treatment has proven highly effective in controlling allergy and occupational asthma flour. It is recommended in patients with severe asthma, which could not be controlled with other treatments such as drugs or immunotherapy.
