Pregnancy outcomes after assisted reproductive technology among women with endometriosis in Ukraine: results a multicenter study.

OBJECTIVE: Aim: To evaluate the association between adverse pregnancy outcome, assisted reproductive technology (ART) and a previous diagnosis of endometriosis in Ukraine. PATIENTS AND METHODS: Materials and Methods: We conducted a multicentre retrospective cohort study was based on infertility surveillance data among women reproductive age from January 1st, 2017 to December 31st, 2021 in Ukraine. The patients from 10 Ukrainian regions who achieved singleton pregnancy by ART were included in this study. Linked hospital, pregnancy/birth and mortality data were used. Logistic regression analysis was performed to calculate odds ratios (OR) and 95 % confidence interval (CI) for the rates of adverse pregnancy outcomes. RESULTS: Results: During study period within the cohort of 11,271 singleton births, 94 women with endometriosis diagnosed before birth delivered 102 infants. Compared with women without endometriosis, women with endometriosis had higher risks of preterm birth [adjusted odds ratio 1.33, 95% confidence interval (CI), 1.23-1.44]. Women with endometriosis had higher risks of antepartal bleeding/placental complications, pre-eclampsia and Caesarean section. There was no association between endometriosis and risk of SGA-birth or stillbirth. CONCLUSION: Conclusions: Endometriosis and ART use are both independently associated with increased risk of preterm birth, antepartum haemorrhage, placenta praevia and planned birth. These findings are clinically relevant to obstetricians for distinguishing high- and low-risk pregnancies. Pregnant women with endometriosis require increased antenatal surveillance.

Adverse pregnancy outcomes associated with endometriosis in Ukraine: results a multicenter study.

OBJECTIVE: Aim: To estimate pregnancy outcomes associated with endometriosis in Ukraine. PATIENTS AND METHODS: Materials and Methods: We performed the multicentre prospective cohort study during the period from January 1st, 2019 to December 31st, 2021. The study included pregnant women aged ≥18 years hospitalized in 17 hospitals from 15 regions of Ukraine. Logistic regression analysis provided odds ratios (OR) with 95% confidence intervals (CI). RESULTS: Results: Of the 27,558 women, 990 (3,6%) reported a diagnosis of endometriosis before pregnancy. In 990 deliveries, women with endometriosis had a higher risk of hypertension in pregnancy (OR 1.2, 95% CI 1.0-1.3), preeclampsia (OR 1.4, 95% CI 1.3-1.5), severe preeclampsia (OR 1.7, 95% CI 1.5-2.3), hemorrhage in pregnancy (OR 2.3, 95% CI 2.0-2.5), placental abruption (OR 2.0, 95% CI 1.7-2.3), placenta previa (OR 3.9, 95% CI 3.5-4.3), premature rupture of membranes (OR 1.7, 95% CI 1.5-1.8), and retained placenta (OR 3.1, 95% CI 1.4-6.6). The neonates had increased risks of preterm birth before 28 weeks (OR 3.1, 95% CI 2.7-3.6), birth before 34 weeks (OR 3.2, 95% CI 2.8-3.6), being small for gestational age (OR 1.5, 95% CI 1.4-1.6), being diagnosed with congenital malformations (OR 1.3, 95% CI 1.3-1.4), and neonatal death (OR 1.8, 95% CI 1.4-2.1). CONCLUSION: Conclusions: Pregnant women with endometriosis are at elevated risk for serious and important adverse maternal, fetal and neonatal outcomes. The magnitude of these complications calls for more intensive antenatal care of pregnant women with endometriosis.

Epidemiology of healthcare-associated endometritis after surgical abortion in Ukraine: results a multicenter study.

OBJECTIVE: Aim: To determine the current prevalence of healthcare-associated endometritis after surgical abortion and antimicrobial resistance of responsible pathogens in Ukraine. PATIENTS AND METHODS: Materials and Methods: We performed a prospective, multicentre cohort study was based on surveillance data of healthcare-associated endometritis after legal induced surgical abortion. Women who underwent induced surgical abortion at gynecological departments of 16 regional hospitals between 2020 and 2022 are included in the study. Definitions of endometritis were adapted from the CDC/NHSN. Antibiotic susceptibility was done by the disc diffusion test as recommended by EUCAST. RESULTS: Results: Among 18,328 women who underwent surgical abortion, 5,023 (27.4%) endometritis were observed. Of all post-abortion endometritis cases, 95.3% were detected after hospital discharge. The prevalence of endometritis in different types surgical abortion was: after vacuum aspiration at < 14 weeks, 23.8%, and after dilatation and evacuation at ≥ 14 weeks, 32%. The most responsible pathogens of post-abortion endometritis are Escherichia coli (24.1%), Enterococcus spp. (14.3%), Enterobacter spp. (12,8%), Pseudomonas aeruginosa (8.3%), Proteus mirabilis (6.6%), Serratia marcescens (6.2%), Staphylococcus aureus (5.9%), and Stenotrophomonas maltophilia (5.7%). A significant proportion these pathogens developed resistance to several antimicrobials, varying widely depending on the bacterial species, antimicrobial group. CONCLUSION: Conclusions: Results this study suggest a high prevalence of endometritis after surgical abortion in Ukraine. A significant proportion of women were affected by endometritis caused by bacteria developed resistance to several antimicrobials. Optimizing the antibiotic prophylaxis may reduce the burden of endometritis after surgical abortion, but prevention is the key element.

Factors associated with female infertility in Ukraine: results a multicenter study.

OBJECTIVE: Aim: To determine the current prevalence of female infertility and characterize and identify risk factors associated with infertility in Ukraine. PATIENTS AND METHODS: Materials and Methods: Multicenter prospective cohort study was conducted from January 2021 to December 2023 in twelve medical centers from nine regions of Ukraine. Definitions of infertility were adapted from the World Health Organization. According to the data collected from questionnaire, participants were divided into infertile and fertile groups and analyzed associated factors. RESULTS: Results: Among all the 7,618 participants in this study, the prevalence of female infertility was 24.3%. The prevalence of primary infertility was 5.9%, and the prevalence of secondary infertility was 18.4%. In logistic multivariate regression analyses, female infertility was associated with age of women (p<0.001), age of first sexual intercourse (p<0.001), history of gynecological surgery (p<0.001), marital status (p<0.001), age of marriage (p<0.001), decreased ovarian reserve (DOR) (p=0.006), family history of infertility (p<0.001), history of cervicitis (p=0.007), history of surgical abortion (p<0.001), history of endometritis (p=0.027), bacterial vaginosis (p=0.023), and aerobic vaginitis (< 0.001). CONCLUSION: Conclusions: Our data suggest a high prevalence of female infertility in Ukraine. The prevalence of secondary infertility was higher than primary infertility. Age of women, age of first sexual intercourse, history of gynecological surgery, marital status, age of marriage, DOR, family history of infertility, history of cervicitis, history of surgical abortion, history of endometritis, bacterial vaginosis, and aerobic vaginitis were associated with infertility.

Postpartum infections and antimicrobial resistance of responsible pathogens in Ukraine: results a multicenter study (2020-2022).

OBJECTIVE: Aim: To determine the current prevalence of postpartum infections and antimicrobial resistance and antimicrobial resistance of responsible pathogens in Ukraine. PATIENTS AND METHODS: Materials and Methods: Multicenter prospective cohort study was conducted from January 2020 to December 2022 in fifteen hospitals from twelve regions of Ukraine. Definitions of healthcare- associated postpartum infection were adapted from the Centers for Disease Control and Prevention's National Healthcare Safety Network. Antibiotic susceptibility was done by the disc diffusion test as recommended by EUCAST. RESULTS: Results: Among 21,968 women, 6,175 (28.1%) postpartum infections were observed. Of all postpartum infection cases, 83.1% were detected after hospital discharge. The postpartum infection rates were 17.3% after cesarean section and 10.8% after vaginal delivery. The most common postpartum infection types were endometritis (17.3%), followed by urinary tract Infection (3.5%), mastitis (3.4%), surgical site infection (excluding endometritis) (2.4%), and episiotomy site infection (1.5%). The predominant postpartum infection pathogens in Ukraine were: Escherichia coli (10.4%), Enterococcus spp. (9.6%), Staphylococcus aureus (6.7%), Pseudomonas aeruginosa (5.8%), Enterobacter spp. (5.8%). In our study pathogens of postpartum infection had differently levels of resistance to antibiotics. CONCLUSION: Conclusions: Our results indicate that postpartum infections requiring medical attention are common in Ukraine and that most postpartum infections occur after hospital discharge, so that use of routine inpatient surveillance methods alone will lead to underestimation of postpartum infection rates. Optimizing the antibiotic prophylaxis may reduce the burden of postpartum infection, but prevention is the key element.

Endometritis after hysteroscopic procedures in Ukraine: results a multicenter study.

OBJECTIVE: Aim: To determine the current prevalence of endometritis after hysteroscopic procedures and antimicrobial resistance of responsible pathogens in Ukraine. PATIENTS AND METHODS: Materials and Methods: Multicenter prospective cohort study was conducted from January 2020 to December 2022 in fifteen hospitals from twelve regions of Ukraine. Definitions of endometritis were adapted from the Centers for Disease Control and Prevention's National Healthcare Safety Network. Antibiotic susceptibility was done by the disc diffusion test as recommended by EUCAST. RESULTS: Results: Among 13,872 patients with hysteroscopic procedures, 1027 (7.4%) endometritis were observed. Of these cases, 0.4% were detected after diagnostic hysteroscopy, and 7.0% were detected after operative hysteroscopy. Of all endometritis cases, 64.2% were detected after hospital discharge. The most commonly reported bacterial species were Escherichia coli (24.3%), followed by Enterobacter spp. (12.7%), Enterococcus spp. (8.3%), Pseudomonas aeruginosa (8.1%), Serratia marcescens (6.8%), Staphylococcus aureus (5.9%), Proteus mirabilis (5.8%), Klebsiella oxytoca (5.1%), Stenotrophomonas maltophilia (4.5%), Klebsiella pneumoniae (4.1%). A significant proportion of patients were affected by endometritis caused by bacteria developed resistance to several antimicrobials, varying widely depending on the bacterial species, antimicrobial group, and geographical region of Ukraine. CONCLUSION: Conclusions: Our data suggest a high prevalence of endometritis after hysteroscopic procedures. Risk for endometritis was higher after operative hysteroscopy compared with diagnostic hysteroscopy. Many most of patients were affected by endometritis caused by bacteria developed resistance to several antimicrobials. These data underscore the importance of tracking antimicrobial resistance of responsible pathogens of HAIs in hospitals.

PREVALENCE OF AEROBIC VAGINITIS AFTER GYNECOLOGICAL SURGERIES AND ASSOCIATED ADVERSE PREGNANCY OUTCOME IN UKRAINE.

OBJECTIVE: Aim: To determine prevalence of Aerobic Vaginitis (AV) after gynecologic surgery, risk factors and antimicrobial resistance of responsible pathogens, and adverse pregnancy outcomes in Ukraine. PATIENTS AND METHODS: Materials and Methods: Multicenter retrospective cohort study was conducted from January 2020 to December 2022 in fifteen medical clinics from eight regions of Ukraine. Smears were analyzed using Donders' classification method and Dong's modified AV diagnosis for Gram stains. Definitions of HAIs were adapted from the CDC/NHSN. Antibiotic susceptibility testing of bacteria was determined by Kirby-Bauer disc diffusion test according to the protocol of the EUCAST. RESULTS: Results: Prevalence of AV among women's undergoing gynecologic surgery in Ukraine was 68.7%. Of the total AV cases, 70.3% were in non-pregnant and 29,7% in pregnant women. The most common pathogen of AV was Escherichia coli, followed by Enterococcus faecalis, Streptococcus agalactiae, Staphylococcus aureus, Enterococcus faecium, Klebsiella pneumoniae, and Pseudomonas aeruginosa. Among the S. aureus strains, 11,6% of MRSA (Methicillin resistant S.aureus) were isolated whereas none of the CoNS were cefoxitin resistant. History of vaginal infection, history of post-operative infection and antibiotic use acted as an important risk factor of AV incidence rate. The presence of AV worsened pregnancy outcomes, by increasing the incidence of preterm birth, the premature rupture of membranes, miscarriage, neonatal jaundice, and neonatal infection. CONCLUSION: Conclusions: Aerobic Vaginitis after gynecological surgeries in Ukraine is a common medical problem in women that is associated with significant morbidity, adverse pregnancy outcome, and hence frequent medical visits.

HEALTHCARE-ASSOCIATED BACTERIAL VAGINOSIS AFTER GYNECOLOGICAL SURGERIES AND ASSOCIATED ADVERSE PREGNANCY OUTCOME IN UKRAINE.

OBJECTIVE: The aim: To determine the prevalence of healthcare-associated bacterial vaginosis after gynecological surgeries and associated adverse pregnancy outcomes in Ukraine. PATIENTS AND METHODS: Materials and methods: Multicenter retrospective cohort study was conducted from January 2019 to December 2021 in eleven medical centers from eight regions of Ukraine. Vaginal cultures were obtained preoperatively from 3,502 women undergoing gynecologic surgery. Diagnosis of Bacterial Vaginosis is based on the Nugent and Amsel criteria. RESULTS: Results: Healthcare-associated bacterial vaginosis (HA BV) was diagnosed in 1,498 of 3,502 women, giving a prevalence rate of 42.8%. HA BV was significantly associated with preterm birth (risk ratio [RR], 2.68; 95% confidence interval [CI], 1.44-4.98), miscarriage (RR, 6.11; 95% CI, 3.22-14.11), low birth weight (RR, 3.20; 95% CI, 1.29-7.94), and premature rupture of membranes (RR, 6.75; 95% CI, 3.11-14.67). CONCLUSION: Conclusions: The HA BV after gynecological surgeries prevalence is high in Ukraine, with a concomitant adverse pregnancy outcome, including preterm birth, low birth weight, premature rupture of membranes, and miscarriage. A significant number of cases of bacterial vaginosis are associated with long-term use of antibiotics to treat post-operative infections.

URINARY TRACT INFECTIONS IN PREGNANT WOMEN IN UKRAINE: RESULTS OF A MULTICENTER STUDY (2020-2022).

OBJECTIVE: The aim: To obtain the first national estimates of the current prevalence rate of urinary tract infections (UTIs) in pregnant women and antimicrobial resistance of causing pathogens in Ukraine. PATIENTS AND METHODS: Materials and methods: Prospective multicentre cohort study was conducted from January 2020 to December 2022. The study population consisted of 36,876 pregnant women from 17 regions of Ukraine. Antibiotic susceptibility was done by the disc diffusion test as recommended by European Committee on Antimicrobial Susceptibility Testing guidelines. RESULTS: Results: A total 29.5% pregnant women were found to have UTIs. Among these cases, 36.5% Asymptomatic bacteriuria, 51.7% Cystitis and 11.8% Pyelonephritis were observed. Of all cases, 87.9% were defined as healthcare-acquired UTIs and 12.1% community-acquired UTIs. The most common uropathogen was Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, and Pseudomonas aeruginosa. Many uropathogens isolated from UTI cases were found to be multidrug resistant. CONCLUSION: Conclusions: UTIs in pregnant women in Ukraine is a common occurrence and many cases are caused by pathogens that are resistant to antibiotics. Optimizing the management and empirical antimicrobial therapy may reduce the burden of UTIs in pregnant women, but prevention is the key element.

VULVOVAGINAL CANDIDIASIS AFTER GYNECOLOGICAL SURGERIES AND ADVERSE PREGNANCY OUTCOME IN UKRAINE: A MULTICENTRE STUDY.

OBJECTIVE: The aim: To investigate the epidemiology and microbiology of vulvovaginal candidiasis (VVC) after gynecological surgeries, and adverse pregnancy outcomes in Ukraine. PATIENTS AND METHODS: Materials and methods: Multicenter prospective cohort study was conducted from January 2020 to December 2022 and recruited pregnant and non-pregnant women aged 15-65 years who had sought medical help for vaginal dysbiosis the seven medical clinic from five regions of Ukraine. RESULTS: Results: Between 2020 and 2022, 2,341 women were followed in gynecological practices, and 1,056 (41.5%) women were diagnosed with VVC during the same period. Of the total VVC cases, 31.9% were in non-pregnant and 68.1% in pregnant women. The use of antibiotics (OR=3.48), use hormonal contracep¬tives (OR=2.75) and pregnancy (OR=1.13) were associated with an increase in the risk of VVC diagnosis. Diabetes mellitus (OR=0.44) were additional risk factors. The most common pathogen of VVC was C. albicans, Nakaseomyces glabratus (C. glabrata), followed by Pichia kudriavzevii (C. krusei), C. parapsilosis, C. tropicalis, C. kefyr, C. guillieromondii, C. lusitaniae, and C. rugosa. We found no significant difference in adverse pregnancy outcomes between Candida-positive and Candida-negative women. CONCLUSION: Conclusions: Vulvovaginal candidiasis after gynecological surgeries in Ukraine is a common medical problem in women that is associated with significant morbidity, and hence frequent medical visits. High prevalence rate of vulvovaginal candidiasis in the present study warrants, the importance of conducting continuous epidemiological surveys to measure changes in species distribution from C. albicans to non-albicans Candida species in Ukraine.

PREVALENCE AND RISK FACTORS OF INFERTILITY IN UKRAINE: RESULTS A MULTICENTER STUDY (2019-2021).

OBJECTIVE: The aim: To assess the current prevalence and identify the risk factors for infertility among couples of reproductive age in Ukraine. PATIENTS AND METHODS: Materials and methods: We conducted a retrospective multicentre cohort study was based on reproductive health surveillance data among married populations from January 1st, 2019 to December 31st, 2021 in Ukraine. Definitions of infertility were used from the WHO. RESULTS: Results: Among all the 6,885 participants in this study, the prevalence of infertility was 25.4%. The prevalence of primary infertility was 5.8%, and the prevalence of secondary infertility was 19.6%. The levels of infertility in the regions of Ukraine had significant differences. It was found that among those women who had primary infertility, more were from rural than urban, while for secondary infertility women the situation was reversed. Infertility was associated with age, history of gynecological surgery, decreased ovarian reserve, age of marriage, long-term air-conditioning environment, and history of endometriosis. There were differences among factors associated with infertility, primary infertility and secondary infertility. The factors associated with primary infertility were age of marriage, age of first sexual intercourse, long-term air-conditioning environment, decreased ovarian reserve and age. A factors associated with secondary infertility were history of gynecological surgery and decreased ovarian reserve. CONCLUSION: Conclusions: The results of this study revealed high level the prevalence rate of infertility among couples of reproductive age in Ukraine is high. This applies to both primary and secondary infertility of married women. The most women who had experienced infertility have not sought medical or professional help for the problem.

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

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.
