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.

CATHETER-ASSOCIATED URINARY TRACT INFECTIONS AFTER CAESAREAN SECTION IN UKRAINE: RESULTS A MULTICENTER STUDY (2020-2022).

OBJECTIVE: The aim: To obtain the first national estimates of the current prevalence rate of catheter-associated urinary tract infections (CAUTIs) after caesarean section (CSEC) and antimicrobial resistance of causing pathogens in Ukraine. PATIENTS AND METHODS: Materials and methods: Prospective multicentre surveillance was conducted from January 2020 to December 2022 in 15 women hospitals of Ukraine. Definitions of CAUTIs were adapted from the CDC/NHSN. Antibiotic susceptibility was done by the disc diffusion test as recommended by European Committee on Antimicrobial Susceptibility Testing guidelines. RESULTS: Results: A total of 15,892 catheterized women undergoing primary CSEC and 13.6% CAUTI were identified. The most common uropathogen was Escherichia coli, Proteus mirabilis, and Enterococcus species followed by Providencia stuartii and Pseudomonas aeruginosa. Many uropathogens isolated from CAUTI cases were found to be multidrug resistant. CONCLUSION: Conclusions: This study showed that CAUTIs in catheterized women undergoing primary CSEC 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 CAUTIs in catheterized women undergoing primary CSEC, but prevention is the key element.

PREGNANCY AND BIRTH OUTCOMES IN FEMALE WITH AND WITHOUT ASSISTED REPRODUCTIVE TECHNOLOGY IN UKRAINE.

OBJECTIVE: The aim: To assess and compare the risk of maternal/perinatal complications and adverse outcomes in pregnancy and childbirth conceived by ART with those conceived naturally in Ukraine. PATIENTS AND METHODS: Materials and Methods: We conducted a retrospective multicenter cohort study from January 1st, 2019 to December 31st, 2021. This study included pregnant women who delivered at 14 Women's Hospitals from 8 regions of Ukraine. RESULTS: Results: A total of 21,162 pregnancies were included. Of these, there were 19,801 natural pregnancies and 1,361 pregnancies after ART. The proportion of ART. pregnancies has increased every year in during study period, peaking in 2021 (6.7%). Data analysis showed that the risks of gestational diabetes, preeclampsia, moderate or severe anemia, liver-related diseases, thyroid-related diseases, preterm birth, placenta previa, postpartum hemorrhage, and cesarean section were significantly increased in ART pregnancy. For neonatal outcomes, women conceived by ART were more likely to have twins. The effects of ART on the risk of premature rupture of membrane, cord entanglement, intrapartum fever, and cesarean section were more pronounced in singletons pregnancies. CONCLUSION: Conclusions: Women conceived by ART were at increased risks of several adverse pregnancy outcomes compared with women conceived naturally. Therefore, prenatal and intrapartum monitoring should be strengthened, and neonatal outcomes should be closely observed for ART pregnancy.

HYPERPLASIA OF THE FEMALE REPRODUCTIVE ORGANS IN UKRAINE.

OBJECTIVE: The aim: To determine the role of infectious diseases as the cause of the Cervical, Ovarian and Breast hyperplasia in Ukraine. PATIENTS AND METHODS: Materials and methods: We conducted a retrospective multicenter cohort study from January 1st, 2020 to December 31st, 2022. This study included patients aged 20-59 years with a diagnosis of hyperproliferative pathology of the women reproductive organs without atypia, who sought medical care for hyperplastic processes admitted to the 12 hospitals from 9 regions of Ukraine. RESULTS: Results: We had examined 4,713 women; out of which 81.1% met the clinical definition of female reproductive organs hyperplasia. Of all hyperplasia cases, most frequently recorded types were breast hyperplasia (41,7%), followed by cervical hyperplasia (31,1%) and ovarian hyperplasia (27,2%). History of Cervicitis (p<0.001), Vaginal cuff infection (p<0.001), Oophoritis (p<0.001), and Mastitis (p<0.001) were identified as independent risk factors of Cervical, Ovarian and Breast hyperplasia. CONCLUSION: Conclusions: This study showed that surgical site infections after obstetric and gynecological operations are is the cause of Cervical, Ovarian and Breast hyperplasia. Therefore, early detection and treatment SSIs can reduce the risk of hyperplasia these organs.

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.

INFECTIONS ASSOCIATED WITH OBSTETRIC AND GYNECOLOGICAL SURGERIES AS A CAUSE OF FEMALE INFERTILITY IN UKRAINE.

OBJECTIVE: The aim: To assess the role of surgical site infections types associated with obstetric and gynecological surgeries as a cause of infertility among women 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 women reproductive age from 2019 to 2021. Definitions of infertility were used from the WHO and surgical site infections were used CDC/ NHSN. RESULTS: Results: Among all the 3,825 of infertility women in this study, the prevalence of surgical site infection (SSI) was 67.9%. The prevalence of SSI among primary infertility group and secondary infertility group women was 67.5% and 71.4%, respectively. There were differences among SSI type associated with infertility, primary infertility and secondary infertility. In logistic multivariate regression analyses, infertility was associated history of induced abortion (p < 0.001), history of obstetric and gynecological surgeries (p < 0.001), Salpingitis (p < 0.001), Oophoritis (p < 0.001), Endometritis (p < 0.001), Adnexa utery (p=0.009), and Pelvic abscess or cellulitis (p=0.043). The main factors associated with primary infertility were history of Salpingitis (33.6%) and Oophoritis (28.2%) after gynecological surgery. A factors associated with secondary infertility were history of Endometritis (27.2%), Pelvic abscess or cellulitis (11.2%), Salpingitis (10.1%), Adnexa utery (9.4%), Oophoritis (4.8%), and Chorioamnionitis (3.9%). CONCLUSION: Conclusions: One of the main causes of infertility in women of reproductive age in Ukraine are SSIs after obstetric and gynecological surgeries, and induced abortion. This applies to both primary and secondary infertility group women's in this cohort study.

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.

PERINATAL INFECTIONS IN UKRAINE: RESULTS OF A MULTICENTER STUDY.

OBJECTIVE: The aim: To obtain the estimates of the сurrent incidence rate of perinatal infections, risk factors, as well as their associated impact on mortality and determine the antimicrobial resistance of responsible pathogens in Ukraine. PATIENTS AND METHODS: Materials and methods: We performed a multicentre retrospective cohort study was based on surveillance data. This study included infants aged 0 to 6 days delivered in 2017-2019 at 11 Ukrainian regional perinatal centers. Definitions of perinatal infections and mortality were used from the CDC/WHO/UNICEF. RESULTS: Results: Of 18,348 liveborn infants, 472 (2.6%) perinatal infections were detected. The incidence of perinatal infection was 25.7 per 1000 live births. The most frequently identified types of infections were: bloodstream infections, 35.6 %, lower respiratory tract infections, 21.4%, Meningitis, 18.2%, Conjunctivitis, 11.9%, skin and soft tissue infections, 6.6%, Dacryocystitis, 3.8%, and urinary tract infections, 2.5%. Early mortality rates from perinatai infections was 51.1%, with an incidence of 13.1 deaths/1000 live births. Potential risk factors the development of perinatal infections and mortality were low birth weight, prematurity, low gestasional age, mode of delivery (manual aid), premature rupture of membranes, preterm premature rupture of membranes, prolonged rupture of membranes, turbid and meconeal amniotic fluid, infection of the mother during labor. resuscitation during delivery, invasive procedure, asphyxia. Main causative agents of perinatal infections were Escherichia coli, Streptococcus agalactiae, Staphylococcus aureus, Klebsiella pneumoniae, CoNS, Enterobacter cloacae, Pseudomonas aeruginosa. CONCLUSION: Conclusions: This study showing that the high incidence rate of perinatal bacterial infections, as well as their associated impact on mortality, and presents a significant burden to the Ukraine.

HEALTHCARE ASSOCIATED INFECTION AFTER LEGAL INDUCED ABORTIONS IN UKRAINE: RESULTS A MULTICENTER STUDY.

OBJECTIVE: The aim: To determine trend of legal induced surgical abortion and to assess the frequency of infection complications after termination of pregnancy in Ukraine. PATIENTS AND METHODS: Materials and methods: We conducted a prospective multicentre cohort study was based on surveillance data of healthcare-associated infection (HAI) after legal induced surgical abortion in women's from January 2017 to 2019 in Ukraine. Definitions of HAI after induced abortion were used from the CDC/ NHSN. RESULTS: Results: The number of surgical abortions in Ukraine increased by 32.8%. A total of 25.9% HAIs were identified after surgical abortion. Of these HAIs, 25.9 were Endometritis, 21.8% Bacterial Vaginitis, 14.3% Parametritis, 13.1% Cervicitis, 9.9% Adnexa utery, 7.8% Salpingitis, 6.3% Chorioamnionitis, and 0.9% other reproductive tract infections. E.coli were most commonly reported, accounting for 25.9% of all organisms, followed by Enterococcus spp. (16.2%), Staphylococcus aureus (15.5%), P. aeruginosa (10.9%), and Enterobacter spp. (10.1%). Antimicrobial resistance in the isolates associated with HAIs showed, among the gram-positive bacteria, that 19.1% and 3.6% of coagulase-negative staphylococci isolates were b-lactam (oxacillin) - and glycopeptide-resistant, respectively. Meticillin resistance was reported in 23.2% of S aureus isolates. Vancomycin resistance was reported in 3.7% of isolated enterococci. Among the gram-negative bacteria, third-generation cephalosporins resistance was found in 33.1% of Klebsiella spp and in 24.1% of E.coli isolates. CONCLUSION: Conclusions: The results of this study revealed high rates of HAIs after surgical abortion and most causing pathogens were associated with resistant to antibiotic strains. This knowledge is essential to develop targeted strategies to surveillance and reduce the incidence of post-abortion infections.
