Xu Q, et al. - Researchers investigated if and how perennial dust mites (DMs) allergy and multiple serum sIgE-mediated autumn pollen allergy coexistence could impact symptom severity in adult patients with allergic rhinitis (AR) in autumn. In the autumn pollen season, they recruited 153 patients with AR and with autumn pollen allergy (Artemisia argyi, ragweed, and hop) with or without DMs allergy. The Chinese version of the visual analog scale was applied: scoring of four rhinitis symptoms (sneezing, rhinorrhea, nasal pruritus, and nasal congestion) and two ocular symptoms (ocular itching and/or grittiness and/or redness, and ocular tearing) was done at nearly the same period. According to the findings, in adult patients with AR and with autumn pollen allergy in autumn, severity of symptoms remained unaffected by the coexistence of perennial DMs allergy and multiple autumn pollen allergy.
