特应性皮炎和慢性荨麻疹患者皮肤点刺试验检查结果分析

目的:了解皮肤点刺试验对特应性皮炎和慢性荨麻疹患者的临床意义。方法:对进行皮肤点刺试验的33例特应性皮炎和20例慢性荨麻疹患者的结果进行总结分析。结果:在特应性皮炎和慢性荨麻疹患者中均以粉尘螨(分别为78.79%,75.00%)和屋尘螨(分别为75.76%,70.00%)的阳性率最高,粉尘螨和屋尘螨在两者中的阳性率比较,差异均有统计学意义(χ2=9.04,P<0.05;χ2=12.35,P<0.05)。牛奶在慢性荨麻疹患者中的阳性率(30.00%)高于在特应性皮炎患者中的阳性率(6.06%),差异有统计学意义(χ2=8.00,P<0.05)。结论:特应性皮炎患者较慢性荨麻疹患者对粉尘螨、屋尘螨更易过敏,而后者较前者对牛奶更易过敏。进行皮肤点刺试验可以有效寻找过敏原,减少病情反复机会。

Analysis on Outcome of Skin Prick Test in Patients with Chronic Urticaria and Patients with Atopic Dermatitis

Objective：To understand clinical significance of skin prick test in chronic urticaria and atopic dermatitis. Methods：The skin prick test results of 20 cases with chronic urticaria and 33 cases with atopie dermatitis were analyzed and summarized. Results：The highest positive rates were dermatophagoides farinae （78.79% and 75% respectively） and house dust mite （75.76% and 70% respectively） both in two groups. There were statistically significance in response rate between two groups （ x^2 = 9.04,P 〈 0.05 ; Z2 = 12.35, P 〈 0. 05 ） , and the positive rate of cow＇s milk （ x^2 = 8.00, P 〈 0. 05 ） also has statistically significant difference. Conclusion： The patients with atopic dermatitis are more allergic to house dust mite and dermatophagoides farinae than those with chronic urticaria, while the result of cow＇s milk is in the contrary. The skin prick test is an effective method to look for specific allergens and reduce relapse of the diseases.
