Local humoral immunity in patients with pollen allergy.
All classes of immunoglobulins and albumin have been studied in different phases of disease, both in blood and in the nasal secretions of 75 patients with pollen allergy. There were 20 healthy persons in the test group. Total correlational analysis was done to determine interdependence of the researched indexes. The percentage of local synthesis of immunoglobulins in the nasal secretion was calculated with the help of Donovan's formula. The results obtained allowed us to find out that the local origin was responsible for 74% of total IgE, 97% of IgA and 10% of IgG in the nasal secretion in patients with pollen allergy. While comparing the results of skin tests with RAST, both in blood and in the nasal secretion, a positive coincidence was found considering the results of skin tests and RAST in serum in 93.8% cases, and in the nasal secretion in 91% of the cases. Coincidence between negative skin tests and the results of RAST in serum was as high as 89% of the cases. In some cases with negative skin test, specific IgE to the corresponding pollen allergens was found in the nasal secretion. In most of the cases there was correlation between allergen specific IgE in blood and in the nasal secretion in the phase of remission (88% of cases) and in the phase of exacerbation (100%). Total and allergen specific IgE in the nasal secretion can be widely used to diagnose allergy "in vitro".
