Abstract:
Objective To explore the relationship between cat fur or dog fur allergens and clinical presentation, as well as allergenic cross-reactivity between cat fur or dog fur allergens and other allergens. Methods Totally 548 children with allergic disorders were assayed with 13 international standard allergen agents by means of SPT. The results were denominated according to the size of skin areola or welt, reference histamine as positive, isotonic Na chloride as negative. Results In 143 children with cat fur allergenic SPT position, 98 cases were boys and 45 cases were girls with an average age of 5. 84 years. In 96 children with dog fur allergenic SPT positive,60 cases were boys and 36 cases were girls with an average age of 6.06 years. The most had occurred in summer. Of them,a large number of cases presented asthma,secondly presented mild cough. Besides, the cross- reactivity of cat fur and dog fur allergenic SPT positive in 64 cases with acarid was most common, followed by latex, which exceeded animal protein, while the cross - reactivity of mold, plant farina and chomophyte allergens were rare. Conclusions About 20% children with allergic disorders are cat fur or dog fur allergenic SPT positive. Cat fur or dog fur allergenic SPT positive results are significantly correlative to age and season, however they are not relative.to sex. Cat fur or dog fur allergens exist correlations with other allergens.
