Research objective: to identify a role of kisspeptine in the regulation of reproduction function.

Materials: literature data by foreign authors for the period from 1985 till 2016.

Methods: systematic analysis and compilation of information in the literature.

Results. The article provides a review of literature data on research of kisspeptine gene and its receptor; it includes description of their role in regulation of reproduction function and mutation in the genes responsible for realization of kisspeptine and neurokinin signaling pathways. Features of kisspeptine secretion in patients with hypogonadotropic hypogonadism, premature sexual development, hyperprolactinemic deficiency of ovaries, polycystic ovarian syndrome, genital endometriosis and opportunity of kisspeptine use in clinical practice as an ovulation trigger are described.

Conclusion. It is necessary to carry out further studies for clarification of kisspeptine role in patients with various diseases and the opportunity of its use as a therapeutic target.

The aim of the study was evaluation of clinical and laboratory manifestations of drug-induced cytolytic syndrome in pregnancy. In the research group included 62 pregnant women with drug-induced liver injury (DILI) in the first trimester of pregnancy. These pregnant women received hormone therapy at the planning stage and/or during pregnancy for the prevention and treatment of miscarriage and had clinical and biochemical manifestations of cytolytic syndrome. Pregnancy after IVF and ovulation induction was in 60.8% of cases. Hormone therapy for pregnant patients received long-term, 85% of pregnant women used estrogen and progestin drugs. DILI during pregnancy characterized by low-symptom or asymptomatic clinical manifestations. DILI manifested cytolytic biochemical syndrome, in which there is isolated increase of transaminase levels, in some cases accompanied by increased level of gamma glutamyl transpeptidase, liver glutamate dehydrogenase and decreased total protein levels, in the first place due to the albumin fraction.

Introduction. More and more researches dedicated to the communication of diseases of the oral cavity of pregnant women with diabetes. It is proved that the intensity of caries and inflammatory periodontal diseases (gingivitis and periodontitis) increase significantly during pregnancy, while the presence of comorbidities, such as diabetes, increase these indexes.

Aim. The aim of the work was to study the dental status of pregnant women with diabetes.

Materials and methods. The study compared women with gestational diabetes mellitus, type 1 diabetes, and type 2 diabetes, to a control group of pregnant women without diabetes. In addition to clinical research methods, liquid-based cytology of the contents of the gingival sulcus was performed.

Results. The results of clinical and laboratory studies have shown that inflammatory diseases of periodontium and teeth within pregnant women with diabetes are more common than within the pregnant women without this disease. It should be noted that the frequency of occurrence and severity of these diseases in the pregnant women with type I diabetes is higher than in the other groups.

Conclusion. Pregnant women with diabetes are at risk for dental disease and require more attention from dentists, endocrinologists and obstetricians. The use of liquid-based cytology method helps in the diagnosis of inflammatory periodontal diseases.

Aim. To study the nature of CYP24A1 gene expression in the placental tissue in women with different saturation of the body with vitamin D during normal pregnancy and preeclampsia.

Materials and methods. Cohort retrospective and prospective study. There were examined 110 pregnant women in Saint Petersburg and Leningrad region, who took multivitamin complex containing 400 IU of vitamin D from 12 weeks of pregnancy. Time of inclusion is from September to June. All pregnant women were taken blood samples with the following determination of the level of 25-hydroxycalciferol, fragments of placental tissue with the following study of mRNA expression of CYP24A1 gene.

Results. There were analyzed two groups of pregnant women. During the analysis of the saturation level of the body with vitamin D there were revealed the following things: the frequency of vitamin D deficiency in the main group was 69.6% in the group of comparison vitamin D deficiency was not found. The frequency of vitamin D insufficiency in the main group was 21.5% in the group of comparison – 18.5%. The frequency of the normal level of vitamin D in the main group was 8.9% in the group of comparison – 81.5%. Differences between the main group and the group of comparison are reliable (p < 0,0001). There revealed a statistically significant increase of the relative expression of mRNA of CYP24A1 gene in the placental tissue in women with preeclampsia (31,8 ± 20,6), in comparison with women with physiological pregnancy (11,2 ± 17,9) (p = 0.03)

Conclusion. In women with preeclampsia low level of vitamin D in blood serum (less than 30 ng/ml) is 5 times more common, that is why insufficiency and deficiency of vitamin D in pregnant women can be attributed to risk factors for the development of preeclampsia. Expression of mRNA of CYP24A1 gene in placental tissue in patients with preeclampsia is three times higher in comparison with patients with a normal pregnancy. Thus, the increased expression of CYP24A1 gene in the placental tissue can be considered as one of the risk factors for the development of preeclampsia.

The aim of this review is to estimate etiologic role of uterine fibroids in female infertility; it based on the results of current studies of infertility in various cases of fibroids (submucous, intramural and subserous). In article was analyzed the efficiency of the treatment of infertility in women with uterine myoma in IVF programs.

Conclusion: a detailed study of endometrial receptivity in women with uterine fibroids is necessary to for personalized strategy in patients with uterine fibroids (myoma) and infertility.
