BACKGROUND: Although the prevalence of @entity2023 ( @entity2023 ) is increasing, relatively little is known about @entity1 characteristics in Spain. The aim of this study was to investigate the clinical profile and therapeutic strategies in @entity1 attending Spanish specialists for @entity2023 caused by grass pollen or house-dust mites (HDMs). METHODS: This was a multicenter cross-sectional epidemiological study of consecutive @entity1 aged >= 5 years with confirmed diagnosis of @entity2023 caused by grass pollen or HDMs attending @entity566 specialists throughout Spain. Demographic and clinical data and information on treatment were collected. RESULTS: Data from 1043 @entity1 were analyzed (524 with grass pollen @entity566 and 519 with @entity566 ; mean age, 27.1 years). Three-quarters had persistent @entity2023 as per the @entity2023 and Its Impact on Asthma ( @entity6048 ) definition, with disease duration of >2 years in 94.3% of those with pollen @entity566 and 85.5% of those with @entity566 . Approximately 38% had concurrent @entity565 . Over one-half of the @entity1 were considered to have gotten worse since the first onset of symptoms. In total, 51.5% did not achieve @entity66 control with pharmacotherapy and 47.7% were treated with immunotherapy (52.2% of HDM allergic @entity1 and 43.2% of grass pollen-allergic @entity1 ). CONCLUSION: The duration of @entity2023 in @entity1 attended for the first time by specialists is long and, in general, the disease does not improve over time and is often not well controlled with pharmacologic interventions. Less than one-half of @entity1 receive allergen-specific immunotherapy that is more often prescribed in @entity566 .
