광주,전남지역 알레르기 환자에서 흡입성 항원에 대한 감작률의 종적 변화와 기온과의 관련성 분석

Background: Recent investigations have reported that climate changes may influence the development of allergic diseases. Objective: We aimed to investigate how sensitization rates to common inhalant allergens would change in association with the alteration in ambient temperature with the passage of time. Method: We included 1,575 subjects who were residing in Gwangju and Chonnam areas and visited our hospital due to allergic symptoms between 2003 and 2008. The data on ambient temperature were obtained from a regional meteorological station. Skin prick tests were performed. Subjects were classified into 5 groups according to the study year: the 2003, 2004, 2006, 2007 and 2008 groups. Result: The regional mean temperatures in Gwangju and Chonnam areas gradually increased with the passage of time. In subjects aged ＜40 years, sensitization rates to tree pollens such as beech (P＜0.05) and alder (P＜0.05) and grass pollens such as rye grass (P＜0.05) and orchard grass (P＜0.05) significantly increased. There were positive correlations between sensitization rates to alder (Rs=0.90, P＜0.05), beech (Rs=0.90, P＜0.05) or rye grass (Rs=0.90, P＜0.05) and the corresponding mean monthly temperature. However, the frequency of atopy and the sensitization rates to dust mites, fungi, cockroach and weed pollens did not increase. Conclusion: Sensitization rates to tree and grass pollens have recently increased in Gwangju and Chonnam areas, which might be associated with global climate changes.
