BACTERIAL INFECTION CAUSES OF PREGNANCY LOSS AND PREMATURE BIRTH IN THE WOMEN IN UKRAINE

Abstract

Objective: The aim: To find out whether or not the presence of pregnancy loss and preterm birth was associated with the history of healthcare-associated infection (HAI) of women reproductive tract.

Patients and methods: Materials and methods: We performed a retrospective cohort study was based on surveillance data. This study included 1,027 fertile women aged 21-50 years admitted to 8 hospitals from 2017-2019 with complaints to pregnancy loss or preterm birth. Definitions HAI of women reproductive tract were used from the CDC/ NHSN.

Results: Results: Of 1,027 fertile women with complaints to pregnancy loss or preterm birth, 702 (68.4%) HAIs of reproductive tract were detected. The predominant HAIs were: postpartum endometritis (19.1), bacterial vaginitis (15.8%), chorioamnionitis (11.3%), vaginal cuff infection (9.1%), and parametritis (5.6%). According to the statistical data, a significant association between HAI of women reproductive tract and the history of pregnancy loss (p < 0.05) was determined. The presence of HAI had no effect on the first trimester miscarriage (p > 0.05), but HAI women reproductive tract had strongly affected the second trimester pregnancy losses (p < 0.05). Main causative agents of HAI were Escherichia coli (31.5%), Enterobacter spp. (18.4%), Klebsiella pneumoniae (12.5%), Enterococcus faecalis (11.6%),Staphylococcus aureus (10.2%), Pseudomonas aeruginosa (8.4%).

Conclusion: Conclusions: This study identified a significant association between healthcare-associated infection of women reproductive tract and a history of miscarriage. However, there was no association between HAI and a history of preterm birth.
