摘要: 目的:探讨鱼尾葵花粉过敏的变应性鼻炎(AR)患者中血清总IgE、特异性IgE和变应原皮肤试验之间的关系。方法:选择429例对鱼尾葵花粉过敏的AR患者为实验组,243例健康体检者为对照组。实验组进行皮肤试验和特异性IgE水平检测,鱼尾葵花粉特异性IgE采用BSA-ELISA法;所有个体均检测血清总IgE水平。结果:实验组血清总IgE的阳性率明显高于对照组的阳性率(分别为66.2%和15.6%,P<0.01);实验组皮肤试验与血清特异性IgE之间差异无统计学意义(χ2=0.758 8,P>0.05);实验组血清特异性IgE和总IgE之间差异有统计学意义(χ2=50.639,P<0.01);海口长居患者与来海南旅游过客血清特异性IgE之间、总IgE之间差异均无统计学意义(P>0.05)。结论:变应原皮肤试验与检测鱼尾葵花粉特异性IgE 2种方法在诊断鱼尾葵花粉过敏的AR中有重要作用,检测血清总IgE对鱼尾葵花粉过敏的AR患者的诊断有参考价值,鱼尾葵花粉过敏的AR患者IgE的阳性率与接触时间之间的关系,有待进一步研究。Abstract: Objective:Exploring the relationship between total and specific IgE in serum and allergen skin test of carvota mitis pollen-induced allergic rhinitis patients.Method:Four hundred and twenty-nine carvota mitis pollen-induced allergic rhinitis patients and 243 healthy control subjects were recruited.The experimental group carried out skin tests.and pollen-specific IgE were also examined by BSA-ELISA method.Total IgE in serum of all of the subjects were determined by ELISA.Result:The positive rate of the total IgE level of the patients were much higher than those of the controls(66.2% vs.15.6%,P<0.01).No statistically significance was found between the positivity of skin test and serum specific IgE of the experimental group(χ2=0.758 8,P>0.05).The difference between serum-specific IgE and total IgE was statistically significant(χ2=50.639,P<0.01).There was no statistical significance of specific IgE and the total IgE in serum between long term residents in Haikou and Hainan Tourisms(P>0.05).Conclusion:Allergen skin test and carvota mitis pollen-specific IgE are two effective methods for the diagnosis of carvota mitis pollen-induced allergic rhinitis.The detection of total IgE in serum of carvota mitis pollen-induced allergic rhinitis provides a reference value for diagnosis.The relationship between concentration of IgE in serum of the carvota mitis pollen-induced allergic rhinitis and allergen contact duration is waiting for further study.
