Prevalence of allergic rhinitis in Beijing--a community survey / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To estimate the prevalence of allergic rhinitis (AR) in a community center in Beijing.@*METHOD@#We randomly investigated a community with 13 900 inhabitents in Beijing by means of questionnaire survey.@*RESULT@#A total of 2000 questionnaires was send out, and 1988 of them were collected, which included 952 males and 1036 females (age: 1 to 96 years old, 128 cases are younger than 14 years old. Among of them, 194 cases (9.76%) were diagnosed as having AR according to epidemiologic definition, including 14 children. The prevalence of AR was 9.68% in adults, with male 10.21% and female 9.18%, 10.94% in children. The prevalence in male are slightly higher than in female both with adults and children but without statistic significance.@*CONCLUSION@#The survey showed the incidence of AR in Beijing are 9.76% in population, adults 9.68%, children (younger than 12) 10.94%. AR patients are more likely to have other allergic diseases.

Evaluation of tryptase measurement in diagnosing allergic diseases / 中华检验医学杂志

Objective To evaluate the use of tryptase in diagnosing allergic diseases.Methods Serum tryptase was measured by Unicap 100 in 35 patients with different types and states of allergic diseases, and 30 healthy volunteers as controls ;Serum tryptases were compared with IgE level.Results Among the 35 allergic patients, 18 cases were with chronic urticaria(4.74?2.54)?g/L; 10 cases had past histories of anaphylaxis shocks(4.86?2.55)?g/L ;7 cases were in acute phase of anaphylaxis(17.4?7.87)?g/L ;30 healthy volunteers(4.36?1.67)?g/L. A statistically significant increase in tryptase concentration was found in patients with acute phase of anaphylaxis compared with other groups.No correlation was found between tryptase concentration and total IgE level.Conclusions Measurement of Serum tryptase level could be an additional tool for diagnosis of anaphylaxis but not chronic urticaria.
