To determine the new criteria for predicting the outcome of pregnancy in women with habitual abortion based on features of differentiation of naive T cells and memory cells in a population of T-helper (CD4+) and cytotoxic T lymphocytes (CD8+). The study involved 61 women with threatened and habitual abortion in the first trimester of gestation. Depending on the outcome of pregnancy was allocated to 3 groups: I went to 39 women whose pregnancy ended in timely delivery; in II - 10 women whose pregnancies ended in premature birth; in III - 11 patients in whom there was a spontaneous miscarriage. Using three-color flow cytometry as peripheral venous blood in populations of CD8+ and CD4+ determined by the content Tn, Tcm, Tem and Temra cells. Statistical analysis was carried out in the program «MicrosoftOffice 2010», «Statistica for Windows 6.0» and MedCalc». When conducting a retrospective assessment, it was found that in the group of patients whose pregnancy ended in preterm delivery, the percentage of CD4 + Tem memory cells was significantly higher and CD4 + Tn lower than in the subgroup with timely delivery (p = 0.013 and p = 0.025, respectively ) In patients with early spontaneous miscarriage, the level of CD8 + Tn significantly decreased against the background of the growth of CD8 + Tem memory cells compared with the same parameters in patients with timely delivery (p = 0.040 and p = 0.014, respectively). Prediction of spontaneous abortion is possible up to CD4+ Tn equal to 34.2% or less (sensitivity - 100.0%, specificity - 56.4%, accuracy - 63.8%), premature birth - if the CD4+ Tn equal to 35, 2% or less (sensitivity - 66.7%, specificity - 74.4% accuracy - 72.9%). Thus, the new criteria will allow additional time to identify risk and assign adequate treatment aimed at prolonging the desired pregnancy.
Perinatal lesions of the Central nervous system (CNS) in newborns occupy a leading place in the structure of perinatal morbidity and subsequent disability of children. To identify the features of the content of sRAGE in pregnant women with threatening preterm labor (UPR) in the period of 22-27 weeks, who subsequently gave birth to children with perinatal CNS lesion. Serum of venous blood of pregnant women with UPR at the term of 22-27 weeks was determined by ELISA once the content of sRAGE. If the value of sRAGE in pregnant women is 659.5 PG/ml or less, perinatal hypoxic lesions of the Central nervous system in newborns are predicted with an accuracy of 75.8% (sensitivity of 82.6%, specificity of 66.7%).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
