THE CHANGES IN CYTOKINS LEVEL AT THE EXACERBATION OF CHRONIC SIMPLE BRONCHITIS CAUSED BY VIRUS OF PARAINFLUENZA OF THE THIRD TYPE IN WOMEN IN THE FIRST TRIMESTER OF PREGNANCY
The contents of interleukin-4 (IL-4), tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) in the blood serum were studied in 89 women in the first trimester of pregnancy. The first group (control) was made out of 25 women with uncomplicated pregnancy; the second had 23 women with the exacerbation of chronic simple bronchitis caused by parainfluenza of the 3rd type with antibody titer 1:16-1:64; the third one consisted of 21 patients with the exacerbation of chronic simple bronchitis induced by parainfluenza infection with antibody titers 1:32-1:128; the fourth group had 20 women with exacerbation of chronic simple bronchitis of parainfluenza etiology with antibody titer 1:64-1:256 at early stages of gestation. In the second group in comparison with the first one there were higher contents of IL-4: 21.1±2.00 pg/ml and INF-γ: 29.5±2.31 pg/ml than in the control group: 12.9±1.16 pg/ml (р<0.001) and 22.3±2.08 pg/ml (р<0.05), respectively. In the third group in comparison with the first one there were higher values of IL-4 (the growth by 132.6%, р<0.001), TNF-α (by 36%, p<0.01) and IFN-γ (by 43%, p<0.01). The patients in the fourth group in comparison with the third one did not have significant differences in TNF-α and IFN-γ. Buy there was the decrease of the level of IL-4 by 11.3% (р<0.05) that shows the imbalance of cytokines in women with exacerbation of chronic simple bronchitis caused by parainfluenza of the third type with antibody titer 1:64-1:256 at early stages of gestation. This may lead to persistent course of infectious-inflammatory process as well as to autoimmune damage of vital organs and the formation of initial placental insufficiency.
