Asthma - allergen, sensitizer
Causes [strength of evidence]:
Notes
Allergens causing allergic asthma can also cause allergic rhinitis. Over 250 agents have been documented to cause immunological occupational asthma, a few broad categories are included here. The haplotype HLA DQB1*0503 is associated with TDI asthma, while allele DQB1*0501 confers protection to TDI. The Th2 type of T helper cells has been associated with an increased likelihood of developing allergies and asthma. Air pollutants may act in conjunction with common allergens to increase sensitivity to other common allergens.
