The study presents data of different authors, as well as its own data on the frequency of multiple trisomies among the early reproductive losses in the I trimester of pregnancy and live fetuses in pregnant women at high risk of chromosomal abnormalities (CA) in I and II trimesters of gestation. The objective: determining the frequency of occurrence of double (DT) and multiple trisomies (MT) among the early reproductive losses in the I trimester of pregnancy and live fetuses in pregnant women at high risk of occurrence of HA in I and II trimesters of gestation; establishment of the most common combinations of diesel fuel and the timing of their deaths compared with single regular trisomy; comparative assessment materinskogo age with single, double and multiple trisomies. Patients and methods. During the period from 1997 to 2016, the first (primary) group of products in 1808 the concept of missed abortion (ST) of I trimester was formed from women who live in Dnepropetrovsk, Zaporozhye, Kirovograd, Cherkasy, Kherson, Mykolaiv regions. The average term of the ST was 8±3 weeks. The average age of women was 29±2 years. The second group (control) consisted of 1572 sample product concepts received during medical abortion in women (mostly residents of Krivoy Rog) in the period of 5-11 weeks of pregnancy, the average age was 32 years. The third group was made prenatally karyotyped fruits (n = 9689) pregnant women with high risk of HA of the above regions of Ukraine, directed the Centre to invasive prenatal diagnosis for individual indications: maternal age, changes in the fetus by ultrasound (characteristic malformations and echo markers HA) and high risk of HA on the results of the combined prenatal screening I and II trimesters. From 11 th to 14 th week of pregnancy, chorionic villus sampling was performed (n=1329), with the 16th week – platsentotsentez (n=2240), 18 th and 24 th week – amniocentesis (n=6120). Results. A comparative evaluation of maternal age and the prevalence anembriony among multiple trisomies. Analyzed 13,069 karyotyped embryonic and fetal I-II trimester of which have found 40 cases of multiple trisomies – 31 cases in the group in 1808 missed abortion (2.84% of total HA), 3 cases including 1 572 induced medabortov and 7 cases during 9689 prenatal research (0.51% of HA). Determined to share the double trisomies preembrionalny, fetal, early, middle and late periods of fetal development. Conclusion. There were no significant differences either in terms of destruction of single and multiple trisomies or in maternal age or in fractions anembrionalnyh pregnancies in these groups. Key words: multiple trisomies, double trisomy, missed abortion, prenatal diagnosis.

The objective: evaluating the effectiveness and safety of the drug complex hinekit during preconception preparation for women with complicated pregnancy loss history and uncomplicated mixed genital infections. Patients and methods. The study involved 65 women with reproductive losses in history, who turned over the abnormal vaginal discharge. Diagnosis of sexual transmitted infections (C. trachomatis, T. vaginalis, HSV-II, HPV), assessment of vaginal microbiota was performed by PCR with detection results in real time. Bacterial Vaginosis verified by the Amsel system. Results. All the examinees in the history have miscarriage in the first (56.9%) or the second (43.1%) trimester of pregnancy. According to the results of the patient survey were divided into clinical groups. In 26.2% of women infectious pathology of the lower genital tract has not been confirmed, 26.2% of patients did not give consent to participate in the study and were formed in the control group that received therapy according to existing clinical settings. 31 patients with mixed genital infection (study group) received complex preparation gіnekit. This positive trend was observed in all the patients of the main group (the disappearance of subjective sensations on average 2.2±0.3 hours). After treatment T. vaginalis, BV were not detected in one patient, active mycotic process in the absence of complaints remained at 4.8% of women, complete eradication of C. trachomatis was achieved in 92.3% of patients. Conclusions. Reducing the duration of treatment of mixed genital infections at the preconception in women with reproductive losses in the history is achieved in terms of clinical, microbiological and pharmaco-economic benefits by prescribtion an gіnekit preparation. Summary of clinical and microbiological effects of the proposed approach is 96.0 ± 0.9%, which corresponds to all requirements for multimodal therapy of genital infections, and no side effects, short course of treatment provides a high compliance of patients (9.2±0.7 points). Key words: mixed genital infections, miscarriages, gіnekit, azithromycin, fluconazole, seknidazol.

This article is devoted to the assessment of the role of ALK5 in the profile of early reproductive losses in the use of assisted reproductive technologies, in particular, by using immunohistochemical study in the group of patients with early spontaneous abortion after the procedure of embryo transfer, a lower level of ALK5 expression in the decidual tissue was revealed (in comparison with control), which may be related to the occurrence of early reproductive losses caused by the imbalance in Th1 / Th2 and its effect on the increase in the concentration of natural killer cells.

The problem of differential prevalence of congenital malformation and reproductive losses in Ukrainian populations becomes especially relevant in the context of increasing the impact of environmental and genetic and demographic factors that can influence their gene pool. The purpose of the study is to determine, during long-term monitoring, the statistically significant differences between the rural populations of Kherson oblast on the incidence of birth defects, involuntary miscarriages and stillbirths, in order to further identify the causes of detected heterogeneity. In calculating the frequency of these indicators in urban and rural populations, the materials of the regional medical-statistical register (medical form 21, 13, 49) are used. The statistical computation of the results obtained (calculation of confidence intervals and the reliability of the differences) was carried out using STATISTICA and Microsoft Excel 9-2000 programs. It has been established that there are significant differences between urban and rural populations in the prevalence of congenital malformations and reproductive losses. In Kherson, for the period of 2000–2013, the average incidence of developmental defects (37.8±11.3‰) and stillbirths (8.2±1.1‰) significantly exceeded similar rates in rural populations (respectively 23.9±1.4‰ and 4.8±0.6‰). However, in rural populations, the incidence of involuntary miscarriages was significantly higher (31.2 ± 1.9 ‰) than in the oblast center (18.9 ± 2.1 ‰). In addition, according to these indicators there is a significant differentiation between rural populations. The prevalence of birth defects in infants in the region is due to an increase in the frequency of “model” defects (r=0.69, p<0.05), which have a significant hereditary component. It was found that in the urban Kherson population, the relatively high frequency of postnatal violations testifies to the weakening of the “sifting” effect of natural selection. On the contrary, selection in rural populations eliminates most of the non-viable embryos in the early stages of pregnancy, as evidenced by the relatively high prevalence of involuntary miscarriages. In the long term, it is necessary to establish the correlation between the indices of the incidence of congenital and hereditary pathology in populations and the parameters of their genetic and demographic structure.

We have studied HLA allogeneic interactions in short-term cultures of lymphocytes from the parents having children with congenital heart defects (CHD), or subject to early reproductive losses. Twentyone married couples (CHD as the main group) who had children with sporadic CHD (interventricular septal defect) without chromosomal diseases were observed. Fifty married couples (a comparison group) had two or more reproductive losses in early gestation (up to 9 weeks), denoted as PNPs (miscarriages, missed abortions, habitual miscarriages. Forty-one families with three or more healthy children represented a control group. Immune response in cell cultures was evaluated by increasing expression of HLA-DR in a mixed culture, as compared to spontaneous lymphocyte cultures. Initial labeling of female and male lymphocytes with monoclonal antibodies to CD45 conjugated to different fluorescent dyes (PC-5 and PC-7) allowed us to evaluate the immune response of female lymphocytes to males and vice versa. The suppressor effect of autologous female serum upon the mixed culture of the lymphocytes of the spouses was also evaluated. Results of the present study showed a difference in HLA allogeneic interactions in the short-term culture of lymphocytes registered for spouses with reproductive losses and children with congenital heart defects. Reproductive losses were associated with a low blocking effect of female auto-serum upon allogeneic HLA interactions in the short-term culture of the lymphocytes of the spouses. Congenital heart defects were associated with high activity of female B-lymphocytes (CD3-/HL-DR+) in short-term mixed culture of lymphocytes from the spouses.

The article is devoted to the analysis of the morphological characteristics of placental tissue in women with early reproductive losses with recurrent miscarriage, depending on the presence of polymorphic variants of metalloproteinases and hemostasis. It was established that in women with recurrent miscarriage, the area of the trophoblast of the placenta is significantly larger (р < 0.003), the area of the chorionic villi is smaller (р < 0.04) than in the group of women with implemented reproductive function. Thrombosis of the chorionic vessels, necrosis and calcinates in the placenta with PNF were detected in 80.0 % (р = 0.001), 93.3 % (р = 0.001), and 30.0 % (р = 0.049) of cases, respectively, which is significantly higher than in the comparison group. In patients with PNP with the T/T genotype of the 735 C/T polymorphism of the MMP-2 gene, the trophoblast area is significant (р < 0.05) more than with the C/C genotype, acute full-back (р = 0.02) and intervillous hemorrhage (р = 0.02). In women with the C/T genotype of the polymorphism 735 C/T of the MMP-2 gene, edema and dystrophic changes in the chorionic villi, placental necrosis are determined more often (р = 0.02) than with the C/C genotype. In carriers of the T allele of the polymorphism 735 C/T of the MMP-2 gene in the placenta, necrosis is significantly more common than in the CC genotype; the carriage of the T allele is also associated with large values of the relative area of the trophoblast and the stromal-intervillous relation, as well as with a smaller value of the ratio of the intervillous space area to the total area of the photograph.

Getah virus (GETV) is a mosquito-borne pathogen that can cause a mild illness and reproductive losses in animals. Although antibodies to GETV have been found in humans, there are no reports of clinical symptom associated with GETV. However, antivirals or vaccine against GETV is still unavailable due to lack of knowledge of the structure of GETV virion. Here, we present the structure of mature GETV at a resolution of 2.8 Å with capsid protein, envelope glycoproteins E1 and E2. Glycosylation and S-acylation sites in E1 and E2 are identified. The surface-exposed glycans demonstrated their impact on the viral immune evasion and host cell invasion. The S-acylation sites strongly stabilize the virion. In addition, a cholesterol and phospholipid molecule are observed in transmembrane hydrophobic pocket, together with two more cholesterols surround the pocket. These structural information are helpful for structure-based antivirals and vaccine design.
