Abstract

Objective: To establish the prevalence of sensitization to dog and cat epithelium in a pediatric population aged 3 to 6 years.

Methods: A descriptive, cross-sectional prevalence study was conducted as part of the study "Prevalence and risk factors for asthma, rhinitis, eczema, and atopy among preschool children in an Andean city." The study population consisted of children from the city of Cuenca, Ecuador, who were administered the culturally validated ISAAC survey and underwent inhalant skin testing.

Results: A total of 600 children were enrolled, with a prevalence of atopy of 33.45% (n = 179), sensitization to dog epithelium of 1.76% (n = 10), and sensitization to cat epithelium of 2.12% (n = 12), representing 5.59% and 6.70% of the atopic population, respectively.

Conclusion: The prevalence of sensitization to cat and dog epithelium in children under 6 years of age is lower than expected in the clinical setting. Future studies should assess the sample size in relation to the prevalence of sensitization to cat and dog epithelium.

[厄瓜多尔昆卡城市学龄前患者对狗和猫上皮的敏感程度]。

目的：了解3 - 6岁儿童对狗和猫上皮的敏感程度。方法：作为“安第斯山脉城市学龄前儿童哮喘、鼻炎、湿疹和特应性反应的患病率和危险因素”研究的一部分，进行了一项描述性的、横断面的患病率研究。研究人群包括来自厄瓜多尔昆卡市的儿童，他们进行了文化验证的ISAAC调查并进行了吸入性皮肤测试。结果：共纳入600名儿童，特应性患病率为33.45% (n = 179)，对狗上皮致敏率为1.76% (n = 10)，对猫上皮致敏率为2.12% (n = 12)，分别占特应性人群的5.59%和6.70%。结论：6岁以下儿童对猫和狗上皮过敏的发生率低于临床预期。未来的研究应评估样本量与猫和狗上皮致敏率的关系。
