Abstract
Aim
To determine the current prevalence of endometritis after hysteroscopic procedures and antimicrobial resistance of responsible pathogens in Ukraine.
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
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.
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.

Salmanov AG et al., 2026 · Polski merkuriusz lekarski : organ Polskiego Towarzystwa Lekarskiego
To estimates of the prevalence rate of urinary tract infections (UTIs) in pregnant women from the Ukrainian-Russian military conflict regions and antimicrobial resistance of causing pathogens. Materials and Retrospective multicenter cohort study was conducted from April, 2022 to May, 2025.The study population consisted of 2,576 pregnant women from the Ukrainian-Russian military conflict regions. Antibiotic susceptibility was done by the disc diffusion test as recommended by EUCAST guidelines. Among 2,576 pregnant women, 1,002 (38.9%) UTIs were observed. The most frequently reported UTI types were cystitis (48.4%) and asymptomatic bacteriuria (39%). Of all UTI cases, 14.6% were defined as acute pyelonephritis. The most common causative agents of UTIs were Escherichia coli (27.6%), Klebsiella pneumoniae (13.9%), Proteus mirabilis (11.2%), Coagulase-negative staphylococci (8.7%), Enterococcus faecalis (8.5%), Enterobacter spp. (7.2%), and Pseudomonas aeruginosa (6.6%). Methicillin-resistance S. aureus (MRSA), vancomycin resistance enterococci (VRE), and extended spectrum beta-lactamases (ESBL) production among Enterobacteriales was found observed in 11.3%, 9.1%, and 29.4% isolates, respectively. Carbapenem resistance was identified in 13.7% of P. aeruginosa strains. This study findings demonstrate the high rate of UTIs in pregnant women from the Ukrainian-Russian military conflict regions and many cases are caused by pathogens that are resistant to antibiotics. Strategies for deterrence include optimal hygiene practices to minimize the risk of bacterial colonization and ascending infection.

To provide an overview of complications and adverse outcomes related to induced abortion in female from the Eastern and Southern Ukrainian-Russian military conflict regions. Material and This are a multicentre combined retrospective and prospective cohort study. All women who underwent induced abortion in Eastern and Southern Ukrainian-Russian military conflict regions between 2022 and 2024 are included in the study. A total of 14,196 induced abortion were performed, 10,630 (74.9%) complications cases were observed. The most complication were infections (71.1%), cervical injury (6.6%), incomplete abortion (5.4%), hemorrhage (5.2%), and uterine perforation (4.9%). The most common infection related to induced abortions was endometritis (21.6%), cervicitis (17.8%), vaginal cuff infections (16.3%), peritonitis (12.3%) and pelvic abscess (10.7%), followed by adnexa utery (8.1%), parametritis (6.7%), salpingitis (5.1%), sepsis (1.3%) and other (0.2%) infections. The main risk factors was increased maternal age, surgical abortion approach, increased gestational age, prior cesarean delivery, presence of a bleeding disorder, fetal demise before the abortion, lack of healthcare facilities, lack of essential medication, lack of personnel and equipment, and surgical inexperience. This study findings demonstrate the high rate of complications related to induced abortion in the Ukrainian-Russian military conflict regions. The ongoing war has led to a decline in the quality of healthcare services and main reason for the high rate of complications and adverse outcomes related to induced abortion in female from the military conflict regions.

Obstetric and gynecological surgical procedures, and surgical site infections as risk for the development of endometriosis: a multicenter study
Salmanov AG et al., 2025 · Wiadomosci lekarskie (Warsaw, Poland : 1960)
Aim this study was to evaluate the incidence of endometriosis in women with a recent history of surgical site infections (SSIs), and obstetric and gynecological surgical procedures. Materials and A retrospective multicenter cohort was conducted on patients who have had obstetric or gynecological surgical procedures performer from January 2022 to December 2024 in 16 hospitals from six Ukrainian regions. Definitions of SSIs were adapted from the Centers for Disease Control and Prevention's National Healthcare Safety Network. The criteria for endometriosis were adapted from the ESHRE endometriosis guideline. The study included 33,126 reproductive women with endometriosis who had 16,724 obstetric and 32,383 gynecologic surgical procedures. The incidence of endometriosis in women with history of obstetric and gynecologic surgical procedures, and SSIs was 25.5% [95% confidence interval (CI), 24.3-26.4], 33.3% (95% CI, 33.0-33.6), and 22,1% (20.8-24.2), respectively. Multivariate analysis identified SSIs, obstetric and gynecological surgical procedures as three factors positively associated with the risk of endometriosis. Factors that increased the odds of endometriosis was SSIs (adjusted odds ratio [AOR], 3.76; 95% CI, 2.29-6.20), and obstetric and gynecological surgical procedures (AOR, 7.91; 95% CI, 3.68-37.3). An SSIs and obstetric and gynecological surgery history increased the odds of an endometriosis >7-fold in the cohort (AOR, 7.96; 95% CI, 3.64-37.2). Obstetric and gynecological surgical injury, and the inflammation resulting from SSIs may play a role in developing endometriosis.

Epidemiology of endometriosis in female evacuated from the Eastern Ukrainian military conflict regions: results a multicenter study (2022-2024)
Salmanov AG et al., 2025 · Wiadomosci lekarskie (Warsaw, Poland : 1960)
To estimate the prevalence and risk factors associated with endometriosis in female evacuated from the Eastern Ukrainian military conflict regions. Materials and A prospective multicenter cohort study was based on surveillance data for endometriosis. 982 women undergoing pelvic surgery were compared to 264 patients unexposed to surgery. The study cohort included women, who underwent a diagnostic and/or therapeutic laparoscopy or laparotomy in 2022-2024. Endometriosis among women was diagnosed visually at laparoscopy/laparotomy or by pelvic magnetic resonance imaging. The prospective multicenter study included 1,246 women. The overall prevalence of endometriosis was 31.5%. Prevalence of the three types of endometrioses included peritoneal/superficial endometriosis, ovarian endometriotic cyst/endometrioma and deep infiltrating endometriosis was 13.8%, 9.8%, and 4.8%, respectively. Three hundred sixty-one women 36,8% in the surgical group and thirty-one women 13.3% in the community treatment group (unexposed to surgery, population cohort) were diagnosed with incident endometriosis. The pelvic pain, infertility and early age at menarche to be a consistent risk factor for endometriosis in both the operative and population cohorts. Data analysis showed that odds were decreased for gravidity, parity, and BMI. Factors that increased the odds of endometriosis diagnosis included dysmenorrhea, older age at first sex, pelvic pain as a surgical indication for laparoscopy, and higher education. Our study findings demonstrate the high prevalence of endometriosis among women in Ukraine. The pelvic pain, infertility and early age at menarche to be a consistent risk factor for endometriosis in both the operative and population cohorts.

Postpartum infections and antimicrobial resistance of responsible pathogens in Ukraine: results a multicenter study (2020-2022)
Salmanov AG et al., 2024 · Wiadomosci lekarskie (Warsaw, Poland : 1960)
To determine the current prevalence of postpartum infections and antimicrobial resistance and antimicrobial resistance of responsible pathogens in Ukraine. Materials and 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. 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. 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.

PREVALENCE OF HEALTHCARE-ASSOCIATED CERVICITIS AND ANTIMICROBIAL RESISTANCE OF THE RESPONSIBLE PATHOGENS IN UKRAINE: RESULTS OF A MULTICENTER STUDY (2019-2021)
Salmanov AG et al., 2022 · Wiadomosci lekarskie (Warsaw, Poland : 1960)
The To obtain the first estimates of the current prevalence of healthcare-associated cervicitis (HACs) and antimicrobial resistance of responsible pathogens in Ukraine. Materials and We conducted a retrospective multicentre cohort study was based on surveillance data from January 1st, 2019 to December 31st, 2021 in Ukraine. Antibiotic susceptibility testing was determined by Kirby-Bauer disc diffusion test according to the protocol of the European Committee on Antimicrobial Susceptibility Testing. Of the 6,885 participants in this study, 1746 women (25.5%) met the clinical definition of cervicitis. Prevalence of HACs and cervcits caused sexually transmitted pathogens were 12.7% and 8.3%, respectively. The incidence of HACs among women with a history of gynecological procedures was 25.4%. The main causes of HACs were legal induced abortions (28.8%), vaginal hysterectomy (23.9%), and postpartum instrumental examination (12.8%). The predominant pathogens of HACs were: Escherichia coli, Enterobacter spp., Klebsiella spp., Staphylococcus aureus, Pseudomonas aeruginosa, Enterococcus faecalis. Methicillin-resistance was observed in 20.8% of S. aureus (MRSA). Vancomycin resistance was observed in 7.4% of isolated enterococci (VRE). Resistance to third-generation cephalosporins was observed in 13.1% Klebsiella spp. and E.coli 17.5% isolates. Carbapenem resistance was identified in 11.6% of P.aeruginosa isolates. The prevalence of ESBL production among E. coli isolates was significantly higher than in K. pneumoniae (33.5%, vs 8.7%). The overall proportion of extended spectrum beta-lactamases (ESBL) production among Enterobacteriaceae was 34.6%. This study showed that the prevalence of healthcare-associated cervicitis in Ukraine is high, and many cases were caused by antibiotic-resistant pathogens.

PREVALENCE OF AEROBIC VAGINITIS AFTER GYNECOLOGICAL SURGERIES AND ASSOCIATED ADVERSE PREGNANCY OUTCOME IN UKRAINE
Salmanov AG et al., 2023 · Polski merkuriusz lekarski : organ Polskiego Towarzystwa Lekarskiego
To determine prevalence of Aerobic Vaginitis (AV) after gynecologic surgery, risk factors and antimicrobial resistance of responsible pathogens, and adverse pregnancy outcomes in Ukraine. Materials and 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. 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. 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
Salmanov AG et al., 2023 · Wiadomosci lekarskie (Warsaw, Poland : 1960)
The To determine the prevalence of healthcare-associated bacterial vaginosis after gynecological surgeries and associated adverse pregnancy outcomes in Ukraine. Materials and 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. 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). 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.
