INDUCTION OF EFFECTORS OF INNATE AND ADAPTIVE IMMUNITY IN THE PROCESS OF THERAPY OF TOPIC FORM OF RECOMBINANT INTERFERON-a2b DURING RESPIRATORY INFECTIONS IN PREGNANT

Abstract

Aim. Study immunologic phenotype of lymphocytes in the process of therapy of topic form of recombinant interferon-a2b during respiratory infections in pregnant. Materials aih. methods. 74 pregnant women from 14 weeks of gestation took part in the study, among their 55 - within 24 hours with symptoms of acute respiratory infection (ARI) of light and medium, severe course of infection, who do not need hospitalization. Group I - 34 pregnan omen with ARI receiving basic therapy with human recombinant interferon-a2b in gel form. Group 11 - 21 pregnant with ARI receiving only basic therapy. Control group had 19 pregnant omen without signs of ARI. Relative content of principle lymphocyte subpopulations was -:udied by flow cytofluorimetry: CD3+, CD3+CD4+, CD3+CD8+, CD3-CD19+, CD3-CD16+56+, CD3-CD8+; immune regulatory index was calculated in blood within 24 hours 'om the onset of the disease and 8 - 10 days later. Results. A disbalance of lymphocyte subpopulations was noted in pregnant women with light or medium severity course of acute 'espiratory infections, that was characterized by an increased content of CD3-CD16+56+ .nd CD3+CD8+, as well as a reduced content of CD3+ and CD3+CD8+. Inclusion of a :opical form of recombinant interferon-oc2b during the first days of development of the disease .as a systemic effect on cell immunity and results in normalization of subpopulation compoition of blood lymphocytes that is characteristic for physiological course of pregnancy. Conclusion. Administration of topic form of recombinant interferon in pregnant with light or medium severity of ARI can be accompanied by activation of factors of innate and adaptive immunity.
