The aim: To obtain the prevalence of postpartum endometritis women and antimicrobial resistance of responsible pathogens in Ukraine. Materials and methods: We performed a retrospective multicenter cohort study. The study population consisted of all women who had a vaginal delivery or cesarean section in 14 Regional Women’s Hospitals of Ukraine. Results: Total 2460 of 25,344 patients were found to have postpartum endometritis, for an overall infection rate of 9.7%. The postpartum endometritis rates were 7.6% after vaginal delivery and 16.4% after cesarean section. Incidence of postpartum endometritis after cesarean section is affected mainly by the mode of delivery (scheduled caesarean deliveries (done before labor starts) – 13.8% and unscheduled caesarean deliveries (done after labor starts) – 22.5%. The predominant pathogens were: Escherichia coli (32.7%), Enterococcus faecalis (13.0%), Streptococcus spp. (12.1%), Klebsiella spp. (10.4%) and Enterobacter spp. (10%). Among the antimicrobial agents tested, the ertapenem, piperacillin/ tazobactam, and cefotaxim were the most consistently active in vitro against Enterobacteriaceae in both vaginal deliveries and after cesarean section infections. The overall proportion of extended spectrum beta-lactamase (ESBL) production among Enterobacteriaceae was 22.8% and of methicillin-resistance in Staphylococcus aureus (MRSA) 15.4%. Conclusions: Postpartum endometritis and antimicrobial resistance of responsible pathogens presents a significant burden to the hospital system. Postpartum infections surveillance is required in all women’s hospitals. This knowledge is essential to develop targeted strategies to reduce the incidence of postpartum infections.

The clinical confirmation of the relationship between uterine leiomyoma and female infertility is of interest to scholars. The aim of our research was to study obstetric history and the level of sex hormones in women of reproductive age with leiomyoma. Materials and methods. The main group consisted of 90 women of reproductive age with uterine leiomyoma, the control group - 45 healthy women. Gynaecological and obstetric history, hormone content in peripheral blood and pelvic vessels (estradiol, progesterone) were analysed. Statistical processing of clinical material was performed using Microsoft Excel, Statistica 7.0, and Statistica 8.0 for Windows. Results. The frequency of infertility in the surveyed women with LM was 18.9 %. One in three patients in the main group (33.3 %) did not give birth, which was statistically different from the healthy women group. In this case, 25.6 % of women in the main group did not use any methods of contraception. It was found that 51.11 % of patients with LM had threatened miscarriage in their history, 37.5 % – complicated delivery. Pathological changes in the concentrations of estradiol and progesterone in the preferential blood and blood vessels of women with fibroids have been identified. We have found that the content of sex hormones in the local bloodstream has a reliable relationship with the location of the myomatous node. Conclusion. The obtained results may indicate that leiomyoma contributes to the reduction of fertility. This is evidenced by the fact that women with LM are more likely to have the risk of miscarriage, complicated delivery and delivery by caesarean section, including complicated one. The findings have made a significant contribution to the further development of effective strategies for the prevention and treatment of infertility in women with fibrotic uterine lesions.
