887例皮肤点刺试验结果分析

目的探讨过敏性疾病常见过敏原的致病状况,为过敏性疾病流行病学研究及临床诊断、治疗和预防提供重要依据。方法应用阿罗格点刺试液进行皮肤点刺试验,同时应用生理盐水和组胺液进行阴性和阳性对照。结果887例行皮肤点刺试验,504例皮试阳性,皮试阳性率56．8％。儿童组皮试阳性率明显高于成人组（X^2检验,P〈0．01）;吸人性过敏原皮试阳性率明显高于食物类过敏原（X^2检验,P〈0．005）;呼吸道过敏病（过敏性鼻炎和／或哮喘）吸人性过敏原皮试阳性率明显高于过敏性皮炎（X^2检验,P〈0．005）;尘螨过敏原（粉尘螨和屋尘螨）皮试阳性率明显高于其他过敏原（X^2检验,P〈0．005）。结论过敏性疾病通常由过敏原致病,吸人性过敏原为常见过敏原,尘螨为首要过敏原。呼吸道过敏病更容易由吸人性过敏原致病。

Result analysis of the 887 eases skin prick tests

Objective To study the pathogenic conditions of the common allergens of the allergic diseases.To provide the important evidence that the epidemiology researches, diagnosis, treatment and prevention of the allergic diseases.Methods The skin prick tests were undertaken by using the prick reagents of the "Allergopharma"company, and histamine hydrogen chloride was used as the positive control and physiologic saline as the negative one.Results The skin prick tests were performed in the 887 cases,504 cases were the positive, the positive rate was the 56.8 percent. The positive rate of the skin prick test is much higher in the children group than the adult one (χ2 inspection, P<0.01). The inhalant allergens much higher than the food ones (χ2 Inspection, P<0.005). The positive rate of the skin prick test to the inhalant allergens is much higher than the respiratory tract allergosis (allergic rhinitis and/or asthma) or the allergic dermatitis (χ2 inspection, P<0.005). The positive rate of the skin prick test is much higher than the mite allergens (Dermatophagoides Farinae and Dermatophagoides Pteronyssinus) or the other ones(χ2 inspection,P<0.005).Conclusion The allergic diseases usually have been caused by the allergens. The inhalant allergens are the common allergens. The mite allergens are the first ones in them. The respiratory tract allergosis has been easier caused by the inhalant allergens than the other ones.
