The association between allergic rhinitis and bronchial asthma, that is, whether it is a seqential process or independent diseases, has not been established. We confirmed that a 25 year-old woman with allergic rhinitis sensitized to Artemisia spp. pollens and house dust mites developed bronchial asthma during a 2 year follow-up period. Severe broncho-constriction was noted after inhalation of methacholine, and the bronchoprovocation test with extract of Korean Artemisia spp. pollen showed early bronchoconstiction. Total IgE and specific IgE antibodies to Artemisia absinthium increased, compared to the initial levels. It is suggested that some patients with allergic rhinitis progress to bronchial ashtma.
