Purpose and tasks: to establish new prognostic criteria of date of prolongation of pregnancy with premature discharge of amniotic fluid on the basis of performance monitoring of cell immunity of mother in the dynamics of observation and the child at the time of completion childbirth. Material and methods. A clinical and laboratory examination of 50 pregnant women, the pregnancy of women was complicated by premature rupture of membranes at 22-34 weeks of gestation. The control group consisted of 40 women with normal pregnancy with the same time of gestation. The traditional methods of clinical and laboratory examination were used to assess the status of pregnant women. The study of peripheral blood was performed with hematological analyzer BC- 3000+. Subpopulations of peripheral blood lymphocytes was studied by cytometry using monoclonal antibodies (apparatus «FAC SCalibur» company «BectonDickinson», USA). Results. The development of leukocytosis with absolute and relative lymphopenia, reduction of CD16+56+lymphocytes and CD19 B lymphocytes were revealed in pregnant women with premature rupture of membranes. The failure of proliferative activity CD3+4+ T-helper cells, the increase of level of CD3+8+ cytotoxic T lymphocytes were revealed at the time of onset of labor after the prolongation of pregnancy. Prolongation of pregnancy at patients with premature rupture of membranes combined with the development of leukocytosis in the fetus, as well as the mother in the same period of observation. At the same time, unlike the parent organism, activation of B-lymphocyte proliferation and humoral immunity at fetus were occurred.

Background/aim: Ureaplasma urealyticum, a common commensal of the female lower genital tract, has been observed as an important opportunistic pathogen during pregnancy. The aims of this study were to determine the degree of cervical colonization with U. urealyticum in pregnant women with risk pregnancy and in pregnant women with normal term delivery and to evaluate the correlation between high-density cervical U. urealyticum colonization and premature rupture of membranes (PROM) as well. Methods. This research was conducted on the samples comprising 130 hospitalized pregnant women with threatening preterm delivery and premature rupture of membranes. The control group consisted of 39 pregnant women with term delivery without PROM. In addition to standard bacteriological examination and performing direct immunofluorescence test to detect Chlamydia trachomatis, cervical swabs were also examined for the presence of U. urealyticum and Mycoplasma hominis by commercially available Mycofast Evolution 2 test (International Microbio, France). Results. The number of findings with isolated high-density U. urealyticum in the target group was 69 (53.08%), while in the control group was 14 (35.90%). Premature rupture of membranes (PROM) occurred in 43 (33.08%) examinees: 29 were pPROM, and 14 were PROM. The finding of U.urealyticum ?104 was determined in 25 (58.14%) pregnant women with rupture, 17 were pPROM, and 8 were PROM. There was statistically significant difference in the finding of high-density U. urealyticum between the pregnant women with PROM and the control group (?? = 4.06, p < 0.05). U. urealyticum was predominant bacterial species found in 62.79% of isolates in the PROM cases, while in 32.56% it was isolated alone. Among the 49 pregnant women with preterm delivery, pPROM occurred in 29 (59.18%) examinees, and in 70.83% of pregnant women with findings of high-density U. urealyticum pPROM was observed. Conclusion. Cervical colonization with U. urealyticum ? 104 is more frequent in pregnant women with risk pregnancy than in pregnant women with normal term delivery. High-density cervical U. urealyticum colonization should be observed as a possible etiological factor for PROM.

Objective: The purpose of this study was to evaluate the prevalence of cervical colonization by genital mycoplasmas in patients with preterm premature rupture of the membranes (PPROM). Method: We studied 225 women between 24 and 36 weeks of gestation with PPROM. Cervical swabs were obtained for genital mycoplasmas and standard vaginal smears of bacterial culture were performed at the time of patients’ admission. In the control group were 225 women with a normal pregnancy. Results: Ureaplasma urealyticum was detected in 68 % (152/225) and Mycoplasma hominis was detected in 28 % (63/225) of the patients with PPROM between 24 and 36 weeks of gestation and. In the control group Ureaplasma urealyticum was found in 17 % (38/225) and Mycoplasma hominis in 15 % (35/225) pregnant women. Conclusion: Our results provide evidence of an association between cervical colonization with genital mycoplasmas and preterm premature rupture of the membranes.

Abstract The aim of this study was to determine possible predictors of an increased frequency of micronucleus (MN) and the impact of thrombophilia on the chromosomal instability in peripheral blood lymphocytes (PBL) of pregnant women in their first trimester. This study was designed as a case-control study on 74 pregnant women. It was performed in the gestational age of 11 to 14 weeks, when blood samples were collected and incubated for 72 hours. The individual MN frequency in PBL was measured by cytokinesis-block micronucleus (CBMN) assay. Women were grouped in control group [≤4 MN/1000 binucleated (BN) cells] and case group (>4 MN/1000 BN cells). Potential mutagenic effects of exogenous/endogenous factors in pregnant women were analyzed. By analyzing the given results, it can be concluded that pregnant women with thrombophilia have 26.69-times more chance of having a frequency of >4 MN/1000 BN than pregnant women with no thrombophilia. Our research was primarily aimed at showing that the presence of thrombophilia was a statistically important predictor of an increased MN frequency in pregnant women and it can predict about one-third of the total variance in MN frequency in the studied population.

Pregnant women with intrauterine growth restriction (IUGR) have an increased risk of adverse perinatal and long-term complications compared with the birth of children with normal body weight. Thus, IUGR is one of the main challenges for the global health system, especially in poor and developing countries. Morpho-functional studies of the placentas help in determining the causes of IUGR, and therefore, timely prevent complications in pregnant women with IUGR. The objective: The purpose of this study is to investigate various morphometric and pathomorphological changes in the placenta, including inflammatory, in cases of IUGR, and to establish a correlation of these results with the etiology and complications for the fetus. Materials and methods. In the current study, 54 placentas of the fetuses with IUGR (the main group) were compared with 50 placentas of the fetuses with normal development (control group). The criteria for the inclusion of IUGR were gestational age more than 30 weeks and all fetuses with a weight less than 10th percentile for this period of pregnancy. The placenta material was studied pathomorphologically with laboratory screening for infection and inflammation. Similarly, the results were determined for placentas of the fetuses with normal development compared to placentas with IUGR. Results. The placenta study showed the presence of calcification in the case of IUGR, as well as in the case of prolonged pregnancy. However, calcification of the placenta in the case of IUGR was more progressive compared with placenta in the normal pregnancy. In addition, the presence of intrauterine infection and inflammation was observed, which could also lead to an adverse outcome for the further progression of pregnancy with IUGR. Conclusion. A comparative macro- and microscopic pathomorphological study of the placentas in the two groups has shown a significant increase in the pathological changes in all the anatomical structures of the fetuses with IUGR. Key words: Intrauterine growth restriction (IUGR), fetal weight, pathomorphological changes of the placenta.

Background: The amniotic membrane plays an important role in maintaining a healthy pregnancy. The main population cells from amniotic membrane include human amnion epithelial cells (hAECs) which have been shown to possess immunomodulatory properties. Objective: The proximity of hAECs with monocyte leads to the generation of tollerogenic dendritic cells. Materials and Methods: hAECs were obtained from normal pregnancy. Peripheral blood monocytes were isolated by anti-CD14 MACS method. Co-cultures of monocytes and hAECs were established in Transwell chambers supplemented with granulocytemacrophage colony-stimulating factor (GM-CSF) and interleukin-4 (IL-4) in the absence and presence of lipopolysaccharide (LPS) to produce immature and mature DCs, respectively. Immunophenotyping of the obtained DCs was done through flow cytometry and the production of cytokines was measured by ELISA. Mixed leukocyte Reaction (MLR) was also performed for the functional assessment of DCs. Results: Immunophenotyping of [hAECs - Immature DC (iDC)] and [hAECs - iDC] + LPS cells revealed that the expression of CD1a, CD80, CD86, CD40, HLA-DR, and CD83 markers showed no significant difference as compared with the control group (iDCs and mDCs alone). In the [hAECs-iDCs] + LPS cells, the percentage of CD14 cells at the ratio of 1:2.5 showed significant differences compared to the control group. The production of IL-10 and IL-12 showed no significant difference in any of the cultures as compared to the control groups. Also, co-cultured DCs did not inhibit proliferation of lymphocyte. Conclusion: Our findings show that factors secreted from cultured hAECs are unable to generate of tollerogenic dendritic cells. To achieve a better understanding of other mechanisms more investigations are needed. Key words: Amniotic membrane, Dendritic cells, Human placenta, Immunomodulation, Monocyte.

Background: Various hematological and immunological changes can occur in pregnancy which could be beneficial for the growth of the fetus and the maintenance of the pregnancy although some of these changes could be hazardous to the fetus and can cause complications during pregnancy. Thus, this study was conducted to investigate the hematological and immunological changes in normal pregnancy and preeclampsia (PE). Materials and Methods: To this end, hematological and immunological changes were evaluated in 62 normal pregnant women and 56 pregnant women with PE. Moreover, 58 healthy non-pregnant women were studied as the control group. The study was done between December 1, 2018 to May 1, 2019 in Chwarbakh Private Clinic and Shorsh Teaching Hospital. The venous peripheral blood from the antecubital vein was used in this study. Results: The results revealed a significant increase in the number of granulocytes, monocytes, and mean platelet (PLT) volume in both normal pregnant women and PE patients in comparison to normal (non-pregnant) controls (P<0.01). In addition, there was a significant correlation between a reduction in their hematocrit (HCT), PLT, and lymphocytes (P<0.01). With regard to immunological changes, a significant increase was also observed in the serum interleukin-4 (IL-4) levels in both normal pregnancy and preeclamptic patients when compared to non-pregnant controls (P<0.01), but gamma interferon was not significantly different. Conversely, there were no significant associations between the serum level of antiphospholipid antibodies and anticardiolipin antibodies in the study groups except for antiphospholipid antibodies which were significantly lower in the third trimester of pregnancy in the preeclamptic patients (P<0.05). Conclusion: In general, significant changes in hematological and immunological parameters were observed in both normal pregnant and PE patients although further studies are required to include more immunological parameters.

Abstract The continual recirculation of lymphocytes between the blood, tissues, and lymph is essential for the coordination and dissemination of immune responses. We have compared the functional and phenotypic properties of lymphocytes isolated from blood and lymph, the two major migratory populations. Lymph-borne lymphocytes migrated readily into the lymphatic recirculation pathway, but greater than one third of all peripheral blood lymphocytes (PBLs) were excluded from the lymphatic circuit and showed an enhanced migration to the spleen. Phenotypic analysis showed that most non-recirculating PBLs were B cells. The migration competence of B cells correlated with the surface expression of CD21 and L-selectin; recirculating B cells expressed both of these molecules, whereas non-recirculating B cells lacked both antigens. These results establish that blood contains distinct pools of lymphocytes that differ in their recirculation competence. Clearly, blood sampling is not an efficient method to directly measure the status of the recirculating immune system, and implies important constraints and restrictions in the interpretation of experimental or clinical data that include phenotypic and quantitative analyses of blood lymphocytes.
