OBJECTIVE: To investigate the effect of nasal instillation of vitamin D3 on patients with allergic rhinitis symptoms including nasal itching, sneezing, clear nasal discharge, and nasal congestion. METHOD: Thirty subjects with allergic rhinitis proved by skin prick test (SPT) and 30 subjects with deviated septum alone were recrui ted and administrated with 300 000 IU of vitamin D3 by nasal instillation weekly. Seven days after the intervention, the four major symptoms including nasal itching, sneezing, clear nasal discharge, and nasal congestion were evaluated by score. RESULT: After intranasal instillation of vitamin D3, the symptoms in allergic rhinitis group in cluding nasal itching, sneezing, nasal discharge and nasal congestion, and serum 25-hydroxyvitamin D level has statistical differences (P < 0.05). CONCLUSION Vitamin D3 could be well absorbed through nasal mucosa. It demonstrated to have significantly effect on serum 25-hydroxyvitamin D to improve the symptoms for patients with allergic rhinitis. Vitamin D3 may be a kind of adjuvant therapy for prevention and treatment of allergic rhinitis.

OBJECTIVE: To explore the distribution of allergen tested by skin prick test (SPT) in about 5,843 allergic rhinitis patients in south Shanghai. METHOD: SPT test was conducted in 5,843 allergic rhinitis patients who came to our clinic from January 2007 to August 2012. The result was analyzed by age, sex and year. RESULT: The top three allergens by percentage are dermatophagoides pteronyssinus, dermatophagoides culinae and fungus among 15 common allergens. Incidence rate between male and female in each year had statistical significance, both of which showed no increasing trend with year. Incidence rates among different age groups aging from 6 to 17 years' old had no statistically significant difference, but statistically significant difference among different age groups existed in other age groups. Incidence rate showed increasing trend with year in age group of 40-65, which was not observed in other groups. The incidence rate showed decreasing trend with age in male and female, while the incidence rate in male was always higher than female. CONCLUSION In south Shanghai, primary allergens causing allergic rhinitis are dermatophagoides pteronyssinus, dermatophagoides culinae and fungus. Statistically significant difference about allergic rhinitis existed in age and sex. SPT has important significance in diagnosis of allergens.
