'The link between allergic rhinitis and asthma has been established: the presence of allergic rhinitis increases the risk of asthma and compared to other allergens sensitisation to HDM [house dust mite] was greatly associated with an increase risk of asthma.'
'The incidence of asthma has doubled since the late 1990s, now affecting 300 million people worldwide.'
'Asthma is a symptom with multiple aetiologies [causes]. Identifying patient phenotypes [genes + environment or traits] is necessary. HDM allergens can trigger both innate [non-specific] and adaptative [specific] immunity. Actually, the application of guidelines is driven by disease severity and not phenotypes. More attention should be given to treating the cause of the disease [gene + environment] and allergen immunotherapy is an answer', Professor Stephen T Holgate.
