[Prognostic value of allergic reaction indicators in the vaccination of children with chronic diseases].

To define the likelihood of development of adverse reactions and complications due to vaccination, the authors conducted clinical and laboratory studies of 115 children aged 1 to 15 years with chronic pathology (allergic diseases, pyelonephritis, immunodeficiency states), vaccinated with diphtheria and tetanus toxoids and pertussis vaccine and diphtheria and tetanus-M anatoxin and revaccinated with diphtheria and tetanus-M anatoxin. The results of the study suggested the prognostic value of allergic reaction indicators (total IgE, DA- and CA-specific IgE, vaccine sensitization detected by the basophil degranulation test) against adverse events and complications of immunization. Vaccination in children with chronic pathology in the presence of higher parameters of allergic reactions, by using hyposensitization therapy, was followed by to the formation of tense antidiphtheria and antitetanus immunity. The given data support the immunological efficiency and safety of immunization of children with chronic diseases against diphtheria and tetanus provided that hyposensitization therapy is performed, by keeping in mind the results of prior clinical and laboratory studies.
