Salivary IgE in allergic patients and normal donors

A prospective study was conducted on 73 allergic patients and 14 normal volunteers in order to measure the IgE concentration in both serum and saliva, and analyze salivary IgE according to the characteristics of the allergic disease. IgE was more frequently detected in saliva from allergic patients than from normal subjects, but its concentration was not significantly higher in the allergic group. The IgE concentration in saliva was not related to serum IgE or to the type of syndromes of the allergic disease, but increased with the symptoms during the pollen season in patients suffering from pollen-induced rhinitis and conjunctivitis.
