BACKGROUND
Component resolved allergen diagnosis allows for a precise evaluation of the sensitization profiles of patients sensitized to felines and canines. An accurate interpretation of these results allows better insight into the evolution of a given patients sensitizations, and allows for a more precise evaluation of their prognoses.
METHODS
70 patients (42 women and 28 men, aged 18-65, with the average of 35.5) with a positive feline or canine allergy diagnosis were included in the research group. 30 patients with a negative allergy diagnosis were included in the control group. The total IgE levels of all patients with allergies as well as their allergen-specific IgE to feline and canine allergens were measured. Specific IgE levels to canine (Can f 1, Can f 2, Can f 3, Can f 5) and feline (Fel d 1, Fel d 2, Fel d 4) allergen components were also measured with the use of the ImmunoCap method.
RESULTS
Monosensitization for only one canine or feline component was found in 30% of patients. As predicted, the main feline allergen was Fel d 1, which sensitized as many as 93.9% of patients sensitized to felines. Among 65 patients sensitized to at least one feline component, for 30 patients (46.2%) the only sensitizing feline component was Fel d 1. Only 19 patients in that group (63.3%) were not simultaneously sensitized to dogs and 11 (36.7%), the isolated sensitization to feline Fel d 1 notwithstanding, displayed concurrent sensitizations to one of the canine allergen components. Fel d 4 sensitized 49.2% of the research group.64.3% of patients sensitized to canine components had heightened levels of specific IgE to Can f 1. Monosensitization in that group occurred for 32.1% of the patients. Sensitization to Can f 5 was observed among 52.4% of the patients.
CONCLUSIONS
Concurrent sensitizations to a few allergic components, not only cross-reactive but also originating in different protein families, are a significant problem for patients sensitized to animals.
背景
组分分辨过敏原诊断能够精确评估对猫和狗过敏患者的致敏谱。对这些结果的准确解读有助于更深入了解特定患者致敏情况的演变，并能更精确地评估其预后。
方法
研究组纳入70例确诊对猫或狗过敏的患者（42名女性和28名男性，年龄18 - 65岁，平均35.5岁）。对照组纳入30例过敏诊断为阴性的患者。测量所有过敏患者的总IgE水平以及他们对猫和狗过敏原的特异性IgE。还使用免疫捕获法测量对狗（Can f 1、Can f 2、Can f 3、Can f 5）和猫（Fel d 1、Fel d 2、Fel d 4）过敏原组分的特异性IgE水平。
结果
30%的患者仅对一种狗或猫的组分致敏。正如预期，主要的猫过敏原是Fel d 1，对猫过敏的患者中有多达93.9%对其致敏。在65例对至少一种猫组分致敏的患者中，30例（46.2%）唯一致敏的猫组分是Fel d 1。该组中只有19例患者（63.3%）不同时对狗过敏，11例（36.7%）尽管仅对猫的Fel d 1致敏，但同时对一种狗过敏原组分致敏。Fel d 4使49.2%的研究组患者致敏。对狗组分致敏的患者中有64.3%对Can f 1的特异性IgE水平升高。该组中32.1%的患者为单一致敏。52.4%的患者对Can f 5致敏。
结论
对多种过敏组分同时致敏，不仅包括交叉反应的组分，还包括源自不同蛋白质家族的组分，这对动物过敏患者来说是一个重大问题。
