[Natural history of allergic reactions to Hymenoptera insect bites].

In 30 patients suffering from systemic allergic reactions following Hymenoptera insect bites risk factors have been evaluated. Life-style, place of living, patients' age, sex and the presence of atopy have been considered. Moreover, the clinical course and value of the intracutaneous quantitative tests have been analysed and their value in both the diagnosis and prognosis of the said reactions have been assessed. Significant correlation between the results of quantitative diagnostic tests and severity of the hypersensitivity to insect poison has been found. A phenomena of the spontaneous diminished skin reactions has been noted. It has been found that only an individual analysis of the natural history might be a base for the choice of appropriate therapy.
