The diagnosis of pollinosis is established on the basis of typical clinical manifestations of the disease in spring and summer. Rinoscopically determine the pale or bluish color of the nasal mucosa, an increase in the inferior nasal shell. The presence of clinical and anamnestic signs of pollinosis is the basis for an allergological examination (conducted outside the flowering season). Since, regardless of the site of the synthesis, allergen-specific IgE antibodies are evenly distributed in the skin, nasal mucosa and serum of patients, endo-initial or conjunctival provocative tests (according to indications), prik test and skin scarification tests, the determination of specific IgE are carried out. During the exacerbation, a large number of eosinophils can be detected in nasal secretions, persistent eosinophilia of peripheral blood (12% or more).
Thus, the diagnosis of pollinosis and allergic dermatitis combined with it, bronchial asthma is based on seasonality of exacerbations, rhinoconjunctival syndrome that occurs during the flowering period of plants, the appearance of spasms of coughing or choking during walks in the countryside, in the field, in the park, in the forest; exacerbation of symptoms in windy weather (increased circulation of pollen in the air); an increase in eosinophils in peripheral blood, eosinophils in the nasal secretion cytogram, in smears-prints from the nasal mucosa and from the conjunctiva. Etiological diagnostics is based on taking into account the seasonality of exacerbations and the flowering calendar of plants characteristic of the relevant region, the conduct of a skin disease test in the period of remission in the conditions of an allergological cabinet.
