目的:探讨慢性湿疹和皮炎患者接触性致敏原及其特点。方法:应用斑贴试验分析178例慢性湿疹和皮炎患者接触性致敏原。结果:列前的致敏原分别是硫酸镍、甲醛、香料、对苯二胺、重铬酸钾、松香、橡胶、白降汞、乙二胺;引起手部湿疹和皮炎患者的致敏原主要是香料和重铬酸钾、躯干和四肢湿疹和皮炎患者的致敏原主要为硫酸镍和松香、头面部湿疹和皮炎患者的主要致敏原为甲醛和香料,脐周皮炎和系统性接触性皮炎患者的致敏原主要为硫酸镍。结论:斑贴试验有助于明确慢性湿疹和皮炎患者的接触性致敏原及其性质。

ObjectiveTo explore the distribution of mite allergens in chronic obstructive pulmonary disease (COPD) patients and the role of allergen in acute exacerbation of COPD (AECOPD) in Hainan Province. MethodsWe selected 65 COPD patients, 58 other patients without allergic disease and 34 healthy subjects as the control group from January to June in 2009. All subjects underwent skin prick test (SPT) to make statistical analysis. We observed the COPD patients for 3 years to analyze the correlation between SPT positive incidence and frequency of acute exacerbation. ResultsThe SPT positive incidence was higher in the COPD group (P<0.05). The most frequent allergen in COPD group was Blomia Tropicalis. But the SPT positive incidence and frequency of acute exacerbation was not obvious correlated (P>0.05). ConclusionThe exogenous allergens may participate in the pathogenesis of COPD. Blomia Tropicalis may be an important allergen of COPD patients in Hainan Province other than Dermatophagoides Pteronyssinus and Dermatophagoides Farinae. But allergy does not play a role in acute exacerbation of COPD.
