Abstract

Aim: To study the influence of season on patch tests results.

Methods: We conducted a retrospective epidemiological study which concerned all the patients of the Tunisian center, who consulted in the Dermato-Allergology Unit of Occupational Medicine Department of Farhat Hached University Hospital-Sousse (Tunisia) over a period of 07 years. All the patients were tested by the European Standard Battery allergens (BSE).

Results: The data of 1000 patch tests were analyzed during the study period. More than half of the patch tests (58.6%) was positive. In winter, 63% of patch tests showed a positive reaction versus 52% of patch tests in summer without a statistically significant association. However, results of lanolin alcohols, epoxy resin, and Sesquiterpene lactone mix varied significantly with season. Atopy was significantly associated with 18.8% of positive reactions in winter and only with 5.2% of positive reactions in summer (p = 0.015).

Conclusion: Seasonal variations in patch tests results were more significant with some allergens of European Standard Battery and in atopic patients.

欧洲基线系列斑贴试验结果的季节变化。

目的:探讨季节对斑贴试验结果的影响。方法:我们进行了一项回顾性流行病学研究，涉及突尼斯中心的所有患者，这些患者在突尼斯法哈特哈奇大学医院-苏塞(突尼斯)职业医学部皮肤过敏科咨询了07年。所有患者均采用欧洲标准电池过敏原(BSE)检测。结果:对研究期间进行的1000次斑贴试验数据进行分析。超过一半(58.6%)的斑贴试验呈阳性。在冬季，63%的斑贴试验显示阳性反应，而在夏季，52%的斑贴试验显示阳性反应，没有统计学上显著的关联。然而，羊毛脂醇、环氧树脂和倍半萜内酯混合物的结果随季节变化显著。特异反应与冬季18.8%的阳性反应显著相关，夏季仅与5.2%的阳性反应显著相关(p = 0.015)。结论:部分欧洲标准电池过敏原及特应性患者的斑贴试验结果季节性差异更显著。
