title: [Analysis of mite-allergic characteristics in patients with allergic rhinitis].
abstract: OBJECTIVE
  To investigate the characteristics of allergic rhinitis sensitized with mite, providing the evidence for the treatment plan of allergic rhinitis in Tianjin area.
  
  
  METHODS
  The medical records of skin prick test results on 2390 allergic rhinitis patients from March 2009 to February 2012 were retrospectively studied. The data of mite sensitivity in gender, age, season, and regional differences were analyzed.
  
  
  RESULTS
  There was no significant difference of the positive rate of Dermatophagoides pteronyssinus and Dermatophagoides farinae between male and female (P > 0. 05); The positive rate of dust mite decreased gradually with the growth of the age in the three groups of < 18,18-39,40-60 years old, but the positive rate of the patients over the age of 60 years old increased then. There were significant differences of positive rate to dust mite in different season (P < 0.05). The positive rate of Dermatophagoides pteronyssinus was the highest in the autumn (55.4%), and the lowest in winter (39.7%). The positive rate of Dermatophagoides farinae was the highest in winter (73.8%), and the lowest in spring (47.2%). There was no significant difference of the positive rate to dust mite between urban and suburb (P > 0.05).
  
  
  CONCLUSIONS
  There were some relationship of the positive rate of dust mite with age and season, but not gender and region among allergic rhinitis in tianjin.
