Subgroup analysis of phase 2 study of ceftolozane/tazobactam in neonates and young infants with pyelonephritis. Microbiol Spectr 2023; 11:e0180023. [PMID: 37698430 PMCID: PMC10581202 DOI: 10.1128/spectrum.01800-23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Accepted: 07/13/2023] [Indexed: 09/13/2023] Open
Abstract
Ceftolozane/tazobactam is approved for the treatment of patients from birth to <18 y old with complicated urinary tract infections (cUTI). This post hoc analysis evaluated the safety, efficacy, and pharmacokinetics (PK) of ceftolozane/tazobactam compared with meropenem in neonates and young infants. NCT03230838 was a phase 2, randomized, active comparator-controlled, double-blind study of patients from birth to <18 y of age with cUTI, including pyelonephritis, given ceftolozane/tazobactam or meropenem in a 3:1 ratio. This subset analysis included only neonates and young infants < 3 mo of age. The microbiologic modified intent-to-treat population (mMITT) included 20 patients (ceftolozane/tazobactam, n = 14; meropenem, n = 6). All patients had pyelonephritis at baseline; two patients in each treatment group had bacteremia (overall 4/20, 20%). Escherichia coli was the most common baseline pathogen (overall 16/20, 80%). Safety and efficacy results were similar between treatment groups and consistent with the overall pediatric population. There were no serious drug-related adverse events (AEs), no discontinuations due to AEs, and no AEs leading to death in either treatment group. For the ceftolozane/tazobactam and meropenem treatment groups, clinical cure rates in the mMITT population were 92.9% and 100%, respectively. The population PK analysis of neonates and young infants demonstrated similar ceftolozane and tazobactam exposures to those of adults, achieving pharmacodynamic targets associated with clinical and microbiologic cure. Ceftolozane/tazobactam has a favorable safety profile and achieves high clinical cure and microbiologic eradication rates in neonates and young infants < 3 mo of age with cUTI and pyelonephritis. IMPORTANCE Extrapolation of antibacterial agent pharmacokinetics from adults to newborns and young infants may not be appropriate; similarly, the clinical manifestations of infectious diseases and outcomes following antibacterial treatment may not be similar. Ceftolozane/tazobactam is an antibacterial drug combination active against Pseudomonas aeruginosa and other multidrug-resistant gram-negative bacteria. A clinical study led to the approval for ceftolozane/tazobactam in patients from birth to 18 y of age who have complicated urinary tract infections, including those with serious kidney infections. Based on data collected during that clinical study, we compared newborns and young infants who were treated with ceftolozane/tazobactam (14 patients) and those who were treated with meropenem (6 patients). We found that ceftolozane/tazobactam treatment of newborns and young infants up to 3 mo of age who have complicated urinary tract infections demonstrated a favorable safety profile and high clinical cure and microbiologic eradication rates, similar to meropenem.

Abstract
BACKGROUND Ceftolozane/tazobactam, a cephalosporin-β-lactamase inhibitor combination, active against multidrug-resistant Gram-negative pathogens, is approved for treatment of adults with complicated urinary tract infections (cUTI). Safety and efficacy of ceftolozane/tazobactam in pediatric participants with cUTI, including pyelonephritis, were assessed. METHODS This phase 2 study (NCT03230838) compared ceftolozane/tazobactam with meropenem for treatment of cUTI in participants from birth to <18 years of age. The primary objective was safety and tolerability. Key secondary end points included clinical cure and per-participant microbiologic response rates at end of treatment (EOT) and test of cure (TOC) visits. RESULTS The microbiologic modified intent-to-treat (mMITT) population included 95 participants (ceftolozane/tazobactam, n = 71; meropenem, n = 24). The most common diagnosis and pathogen were pyelonephritis (ceftolozane/tazobactam, 84.5%; meropenem, 79.2%) and Escherichia coli (ceftolozane/tazobactam, 74.6%; meropenem, 87.5%); 5.7% (ceftolozane/tazobactam) and 4.8% (meropenem) of E. coli isolates were extended-spectrum β-lactamase-producers. Rates of adverse events were similar between treatment groups (any: ceftolozane/tazobactam, 59.0% vs. meropenem, 60.6%; drug-related: ceftolozane/tazobactam, 14.0% vs. meropenem, 15.2%; serious: ceftolozane/tazobactam, 3.0% vs. meropenem, 6.1%). Rates of clinical cure for ceftolozane/tazobactam and meropenem at EOT were 94.4% and 100% and at TOC were 88.7% and 95.8%, respectively. Rates of microbiologic eradication for ceftolozane/tazobactam and meropenem at EOT were 93.0% and 95.8%, and at TOC were 84.5% and 87.5%, respectively. CONCLUSIONS Ceftolozane/tazobactam had a favorable safety profile in pediatric participants with cUTI; rates of clinical cure and microbiologic eradication were high and similar to meropenem. Ceftolozane/tazobactam is a safe and effective new treatment option for children with cUTI, especially due to antibacterial-resistant Gram-negative pathogens.

Abstract
The use of catheters and bladder catheters in hospitals can increase the risk of bacterial infections. This study aimed to identify the bacterial strains involved in catheter-related infections (CRI) in southern Benin hospitals. The study included 407 samples, including 95 catheter tip samples and 312 urine samples collected from bladder catheters from patients on the first day and 48 h after admission. The catheter tip samples were analyzed using traditional bacterial isolation and identification methods, while the urine samples were analyzed using VITEK-2. Antibiotic sensitivity was tested using the Kirby Bauer method, and virulence and resistance genes were detected through standard PCR. The results showed a predominance of Escherichia coli (53.5%), Klebsiella pneumoniae (23.3%), and Enterobacter aerogenes (7.0%) among Gram-negative bacilli, and coagulase-negative Staphylococcus as the most identified cocci. Bacterial susceptibility to antibiotics showed variable levels of resistance, with blaTEM being detected in 42.9% of identified bacterial species, followed by blaSHV (26.2%) and blaCTX-M-15 (16.7%). The blaNDM gene was only found in three identified bacterial strains, while vanA and vanB genes were detected in 3.2% of strains with a prevalence of 55% for the mecA gene. A prevalence of 18.8% for fimH was noted for the virulence genes. In conclusion, this study highlights the importance of following proper hygiene and aseptic practices during catheterization to effectively prevent CRIs. These findings should be used to improve interventions in hospitals and reduce healthcare-associated infections in developing countries.

Abstract
Bacterial urinary tract infections (UTI) commonly occur in children; if left untreated, they may result in severe consequences such as uro-sepsis and renal damage. This study aimed to determine the bacterial profile, antimicrobial susceptibility patterns and associated factors among paediatric patients suspected of urinary tract infections in Arba Minch General Hospital (AMGH). An institution-based cross-sectional study was conducted from 01 October 2020 to 31 January 2021. A convenient sampling technique was used to recruit the participants; data were collected using a pre-tested questionnaire. To quantify the bacteria (as per the Kass count, >105CFU/ml), midstream urine samples were streaked onto bacteriological media. Isolates were identified by following standard procedures. The antibiotic susceptibility test was performed as per the Kirby-Bauer disc diffusion technique. Data were analyzed using SPSS software. Out of the 246 children included, 38 (15.4%) were found to be positive for significant bacteriuria. Isolates of Escherichia coli, 9/38 (23.7%), and Staphylococcus aureus, 9/38 (23.7%), were the most predominant. The majority of Gram-negative bacterial (GNB) isolates showed resistance towards amoxicillin-clavulanate (89.5%), ampicillin (84.6%), and ceftazidime (81%). Likewise, 76.9 and 76.5% of Gram-positive bacteria (GPB), respectively, had shown resistance towards co-trimoxazole and tetracycline. Multi-drug and extensively drug resistance were detected respectively in the case of 68.4 and 15.8% of the total isolates; ESBL production was found in 57.1% of GNB, whereas 55.6% of S. aureus were methicillin-resistant S. aureus (MRSA). The process of un-circumcision was significantly associated with UTI [(adjusted odds ratio= 3.578; 95% confidence interval: 1.263 - 10.13; p=0.016)].

Abstract
Background Antibiotic resistance is growing worldwide due to the magnitude of the rational and irrational use of antibiotics, particularly in children. Evidence regarding the use of antibiotics without a prescription in Saudi children is limited, and the factors that affect frequent antibiotic use in children are poorly understood. Therefore, we investigated the rate of the use of antibiotics in Saudi children reported by their parents and the factors associated with parents that affect the use of antibiotics in children. Methods A cross-sectional survey using a 27-item self-administered questionnaire was conducted among parents living in Saudi Arabia. Parents with at least one child aged 16 years or less were eligible to participate in the study. The results were analyzed via descriptive and inferential statistics. Results A total of 284 parents participated in the study. Of the participants, 81% (n = 230) had given their children at least one course of antibiotics, and 57% of their children were male (n = 164). Many parents did not have a regular general practitioner (GP) for providing care to their children (n = 201, 70%). Further, 164 (n = 71%) parents administered antibiotics without consulting a general practitioner. Neither the parent and child demographics nor the parent knowledge and behavioral variables were significantly associated with the parent's variable of interest in the administration of antibiotics. Conclusions Generally, parents reported alarmingly high rates of antibiotic use among their children. Reducing the unnecessary use of antibiotics in children is crucial for preventing antimicrobial resistance. No apparent statistically significant factor was identified as being associated with antibiotic use. The need for additional measures to limit antibiotic use in children may be warranted. Initiatives to educate parents for consulting a regular general practitioner for their children before administering antibiotics may improve the health outcomes of children.

Abstract
Purpose of Review Urinary tract infection (UTI) in children is a major source of office visits and healthcare expenditure. Research into the diagnosis, treatment, and prophylaxis of UTI has evolved over the past 10 years. The development of new imaging techniques and UTI screening tools has improved our diagnostic accuracy tremendously. Identifying who to treat is imperative as the increase in multi-drug-resistant organisms has emphasized the need for antibiotic stewardship. This review covers the contemporary management of children with UTI and the data-driven paradigm shifts that have been implemented into clinical practice. Recent Findings With recent data illustrating the self-limiting nature and low prevalence of clinically significant vesicoureteral reflux (VUR), investigational imaging in children has become increasingly less frequent. Contrast-enhanced voiding urosonogram (CEVUS) has emerged as a useful diagnostic tool, as it can provide accurate detection of VUR without the need of radiation. The urinary and intestinal microbiomes are being investigated as potential therapeutic drug targets, as children with recurrent UTIs have significant alterations in bacterial proliferation. Use of adjunctive corticosteroids in children with pyelonephritis may decrease the risk of renal scarring and progressive renal insufficiency. The development of a vaccine against an antigen present on Escherichia coli may change the way we treat children with recurrent UTIs. Summary The American Academy of Pediatrics defines a UTI as the presence of at least 50,000 CFU/mL of a single uropathogen obtained by bladder catheterization with a dipstick urinalysis positive for leukocyte esterase (LE) or WBC present on urine microscopy. UTIs are more common in females, with uncircumcised males having the highest risk in the first year of life. E. coli is the most frequently cultured organism in UTI diagnoses and multi-drug-resistant strains are becoming more common. Diagnosis should be confirmed with an uncontaminated urine specimen, obtained from mid-stream collection, bladder catheterization, or suprapubic aspiration. Patients meeting criteria for imaging should undergo a renal and bladder ultrasound, with further investigational imaging based on results of ultrasound or clinical history. Continuous antibiotic prophylaxis is controversial; however, evidence shows patients with high-grade VUR and bladder and bowel dysfunction retain the most benefit. Open surgical repair of reflux is the gold standard for patients who fail medical management with endoscopic approaches available for select populations.

Abstract
BACKGROUND Febrile urinary tract infection (fUTI) is a common bacterial infection among children. This study investigated the risk factors for fUTI caused by cefazolin-resistant bacteria in children. METHODS The medical records of patients with fUTI hospitalized between April 2014 and March 2020 were retrospectively analyzed. The patients were divided into two groups based on the cefazolin susceptibility of the infection-causing bacteria: cefazolin-resistant and cefazolin-susceptible groups. RESULTS The records of 80 patients were evaluated. The median age was 5.0 months (range 0.5-119.4 months). Cefazolin-susceptible bacteria were detected in 60 patients (75.0%). Significant differences were noted between the cefazolin-resistant and cefazolin-susceptible groups regarding UTI-related antimicrobial prophylaxis and recurrence of UTI within 3 months (P = 0.0318 and P = 0.00876, respectively). However, no significant differences were observed between these two groups regarding renal anomalies, or UTI history. Logistic regression analysis revealed that the recurrence of UTI within 3 months was an independent, significant risk factor for cefazolin-resistant fUTI (odds ratio 3.81, 95% confidence interval: 1.07-13.5, P = 0.0388). Six patients who were empirically treated with antibiotics ineffective against the infection-causing bacteria recovered from fever before these antibiotics were switched to those effective against the infection-causing bacteria. CONCLUSIONS In children, a recurrence of UTI within 3 months is a risk factor for fUTI caused by cefazolin-resistant bacteria. Recognizing these risk factors before initiating fUTI treatment in children may support treatment with narrower-spectrum antibiotics, such as first-generation cephalosporins (e.g., cefazolin).

Abstract
Febrile urinary tract infection (UTI) is currently considered the most frequent cause of serious bacterial illness in children in the first 2 years of life. UTI in paediatrics can irreversibly damage the renal parenchyma and lead to chronic renal insufficiency and related problems. To avoid this risk, an early effective antibiotic treatment is essential. Moreover, prompt treatment is mandatory to improve the clinical condition of the patient, prevent bacteraemia, and avoid the risk of bacterial localization in other body sites. However, antibiotic resistance for UTI-related bacterial pathogens continuously increases, making recommendations rapidly outdated and the definition of the best empiric antibiotic therapy more difficult. Variation in pathogen susceptibility to antibiotics is essential for the choice of an effective therapy. Moreover, proper identification of cases at increased risk of difficult-to-treat UTIs can reduce the risk of ineffective therapy. In this review, the problem of emerging antibiotic resistance among pathogens associated with the development of paediatric febrile UTIs and the best potential solutions to ensure the most effective therapy are discussed. Literature analysis showed that the emergence of antibiotic resistance is an unavoidable phenomenon closely correlated with the use of antibiotics themselves. To limit the emergence of resistance, every effort to reduce and rationalise antibiotic consumption must be made. An increased use of antibiotic stewardship can be greatly effective in this regard.

Abstract
The development and spread of antibiotic resistance is an increasingly important global public health problem, even in paediatric urinary tract infection (UTI). In light of the variability in the data, it is necessary to conduct surveillance studies to determine the prevalence of antibiotic resistance in specific geographical areas to optimize therapeutic management. In this observational, retrospective, multicentre study, the medical records of 1801 paediatric patients who were hospitalised for UTI between 1 January 2012, and 30 June 2020, in Emilia-Romagna, Italy, were analysed. Escherichia coli was the most frequently detected pathogen (75.6%), followed by Klebsiella pneumoniae (6.9%) and Pseudomonas aeruginosa (2.5%). Overall, 840 cases (46.7%) were due to antimicrobial-resistant uropathogens: 83 (4.7%) extended spectrum beta-lactamase (ESBL)-producing, 119 (6.7%) multidrug resistant (MDR) and 4 (0.2%) extensively drug resistant (XDR) bacteria. Empirical antibiotic therapy failed in 172 cases (9.6%). Having ESBL or MDR/XDR uropathogens, a history of recurrent UTI, antibiotic therapy in the preceding 30 days, and empirical treatment with amoxicillin or amoxicillin/clavulanate were significantly associated with treatment failure, whereas first-line therapy with third-generation cephalosporins was associated with protection against negative outcomes. In conclusion, the increase in the resistance of uropathogens to commonly used antibiotics requires continuous monitoring, and recommendations for antibiotic choice need updating. In our epidemiological context, amoxicillin/clavulanate no longer seems to be the appropriate first-line therapy for children hospitalised for UTI, whereas third-generation cephalosporins continue to be useful. To further limit the emergence of resistance, every effort to reduce and rationalise antibiotic consumption must be implemented.

Abstract
The prevalence of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae urinary tract infections (UTIs) is increasing worldwide. We investigated the prevalence, clinical findings, impact and risk factors of ESBL E. coli/K. pneumoniae UTI through a retrospective review of the medical records of children with UTI aged <15 years admitted to Prince of Songkla University Hospital, Thailand over 10 years (2004–2013). Thirty-seven boys and 46 girls had ESBL-positive isolates in 102 UTI episodes, compared with 85 boys and 103 girls with non-ESBL isolates in 222 UTI episodes. The age of presentation and gender were not significantly different between the two groups. The prevalence of ESBL rose between 2004 and 2008 before plateauing at around 30–40% per year, with a significant difference between first and recurrent UTI episodes of 27.3% and 46.5%, respectively (P = 0.003). Fever prior to UTI diagnosis was found in 78.4% of episodes in the non-ESBL group and 61.8% of episodes in the ESBL group (P = 0.003). Multivariate analysis indicated that children without fever (odds ratio (OR) 2.14, 95% confidence interval (CI) 1.23–3.74) and those with recurrent UTI (OR 2.67, 95% CI 1.37–5.19) were more likely to yield ESBL on culture. Congenital anomalies of the kidney and urinary tract were not linked to the presence of ESBL UTI. In conclusion, ESBL producers represented one-third of E. coli/K. pneumoniae UTI episodes but neither clinical condition nor imaging studies were predictive of ESBL infections. Recurrent UTI was the sole independent risk factor identified.

Abstract
BACKGROUND The prevalence of extended-spectrum beta-lactamase producing Εnterobacteriaceae (ESBL-PE) is increasing globally. ESBL-PE are an important cause of urinary tract infections (UTIs) in children. We aimed to characterize the clinical presentation, treatment and outcomes of childhood UTI caused by ESBL-PE in Europe. METHODS Multicenter retrospective cohort study. Children 0 to 18 years of age with fever, positive urinalysis and positive urine culture for an ESBL-PE uropathogen, seen in a participating hospital from January 2016 to July 2017, were included. MAIN OUTCOME MEASURES Primary outcome measure: day of defervescence was compared between (1) initial microbiologically effective treatment (IET) versus initial microbiologically ineffective treatment (IIT) and (2) single initial antibiotic treatment versus combined initial antibiotic treatment. SECONDARY OUTCOME MEASURES Clinical and microbiologic failure of initial treatment. RESULTS We included 142 children from 14 hospitals in 8 countries. Sixty-one children had IET and 77 IIT. There was no statistical difference in time to defervescence for effective/ineffective groups (P = 0.722) and single/combination therapy groups (P = 0.574). Two of 59 (3.4%) and 4/66 (6.1%) patients exhibited clinical failure during treatment (P = 0.683) when receiving IET or IIT, respectively. Eight of 51 (15.7%) receiving IET and 6/58 (10.3%) receiving IIT patients (P = 0.568) had recurring symptoms/signs suggestive of a UTI. Recurrence of a UTI occurred 15.5 days (interquartile range, 9.0-19.0) after the end of treatment. CONCLUSIONS Time to defervescence and clinical failure did not differ between IET/IIT groups. Non-carbapenem beta-lactam antibiotics may be used for the empiric treatment of ESBL febrile UTIs, until susceptibility testing results become available.

Abstract
Introduction Urinary tract infection (UTI) is one of the most common bacterial infections in childhood, and the increasing rate of antibiotic resistance to the commonly prescribed antimicrobial agents against it has become a major concern. The aim of this study was to determine the antibiotic resistance and genotyping of bacteria isolated from urine cultures in patients referred to the Children’s Medical Center, Tehran, Iran. Methods During the 1-year period, antimicrobial susceptibility profiles of strains isolated from patients with UTI were determined. Typing of the isolates causing nosocomial infections was performed by random amplified polymorphic DNA (RAPD) analysis, and the results were analyzed by Gelcompar II software. Results In this study, 203 children (130 girls and 73 boys) were included. The patients’ age ranged from 1 day to 16 years (IQR average=4 months to 4 years). The most frequent isolated organisms were Escherichia coli (118 isolates, 58%), followed by Klebsiella pneumoniae (30 isolates, 15%). Sixty-two strains (18 strains of E. coli, 13 strains of K. pneumoniae, 11 strains of Enterococcus faecium, and five strains of Burkholderia cepacia complex) had criteria of nosocomial infection. A high resistance rate to trimethoprim-sulfamethoxazole (69%) and cefotaxime (60%) was reported in E. coli and K. pneumoniae strains, respectively. Pseudomonas aeruginosa strains showed high sensitivity to amikacin (100%). All E. faecium strains were susceptible to trimethoprim-sulfamethoxazole (100%), and 23% of the strains were resistant to vancomycin. The analysis of RAPD-typing revealed the presence of three clusters in E. coli, two clusters in E. faecium, and one clone in K. pneumoniae. Besides, four out of five isolates of B. cepacia complex had more than 90% genetic similarity. Conclusion The most frequent isolated pathogen was E. coli, and an increasing rate of antibiotic resistance to the commonly prescribed antimicrobial agents such as trimethoprim/sulfamethoxazole and cephalosporins was observed. Moreover, the results of this study showed the presence of clones with ≥80% similarity in E. coli, K. pneumoniae, E. faecium, and B. cepacia complex isolates; therefore, the transmission of nosocomial infections from one patient to another or one ward to another is probable.

Abstract
BACKGROUND Increased antimicrobial resistance is a problem in managing urinary tract infections (UTI). With this study we assessed the resistance patterns of urinary isolates in children with UTI between January 2017 and January 2018. METHODS A retrospective cohort study was conducted. Among 5,443 isolates, a total of 776 UTI episodes in 698 patients were included. Patients' gender, age, voiding dysfunction, UTI history, prophylaxis status, and presence of vesicoureteral reflux were noted. Patients were divided into three age groups: group 1 for ages ≤12 months; group 2 for ages 13-60 months; and group 3 for ages >60 months. The susceptibilities of etiologic agents to different antimicrobials were explored. RESULTS Median age was 54 months (range 1 month-21 years); male to female ratio was 1:5. The most common causative agent was Escherichia coli (83% of the cases), followed by Klebsiella pneumoniae (7.5%). Resistance to ampicillin (62.6%) and co-trimoxazole (39.8%) were remarkable in all isolates. Overall extended-spectrum beta-lactamase (ESBL) positivity was 23.5%. The highest resistance rates, higher ESBL positivity (28.6%), and K. pneumoniae frequency (13.5%) were observed in group 1. Ceftriaxone resistance was significantly low (0.5%) in the ESBL (-) group, which constituted the majority of the isolates. Higher resistance rates were observed among the patients on prophylaxis compared to those off prophylaxis (P < 0.001). CONCLUSION Ceftriaxone can still be used for empirical treatment; however, initial urine culture results are crucial due to high ESBL positivity. Special consideration must be taken for patients under 1 year of age. Periodical surveillance studies are needed to explore the changing resistance patterns of uropathogens and modify treatment plans.

Abstract
INTRODUCTION Extensively drug-resistant (XDR) is defined as isolates sensitive only to two or fewer antimicrobial categories. This paper aims to present the treatment outcome and identify factors associated with poor clinical response among children with XDR gram-negative urinary tract infection (UTI). METHODS This is a retrospective cohort conducted at a tertiary pediatric hospital from January 2014 to June 2017. All patients diagnosed with culture-proven XDR gram-negative UTI were identified and analyzed. Descriptive statistics were used to summarize demographic and clinical characteristics. Patients were categorized according to treatment outcomes: success vs. failure. Univariate analysis and multivariate logistic regression were used to assess statistical differences between the groups and determined patient variables that are predictive of poor response. Odds ratio (OR) and corresponding 95% confidence interval (CI) were generated. RESULTS A total of 29 (19.2%) XDR gram-negative pediatric UTIs were identified within the 42-month study period. No significant differences were noted in demographic characteristics between the groups. Treatment outcome of XDR gram-negative UTI patients showed that combination therapy with colistin had the highest success rate (40.9%), followed by non-colistin (36.4%) and combination therapy without colistin (22.7%). However, univariate analysis showed no significant difference among the different treatment groups (p=0.65). On multivariate logistic regression, receiving immunosuppressant and the presence of indwelling urinary catheters were independent predictors of poor clinical response among pediatric patients with XDR gram-negative UTI (OR 19.44, 95% CI 1.50-251.4, p=0.023 and OR 20.78, 95% CI 1.16-371.28, p=0.039; respectively). CONCLUSIONS The treatment success rate of XDR gram-negative pediatric UTI ranged from 22.7-36.4%. This finding emphasizes the need to advocate antibiotic stewardship to prevent further increase in XDR UTIs. Indwelling urinary catheters and receipt of immunosuppressants are associated with poor clinical outcome.

Abstract
BACKGROUND The aim of this study was to investigate the risk factors for acquisition of extended spectrum β-lactamase (ESBL)-producing bacteria in community-acquired urinary tract infection (UTI) and to evaluate their antimicrobial resistance. METHODS The medical records of hospitalized children were retrospectively evaluated. Children with ESBL-producing bacteria UTI were matched with controls with non-ESBL-producing bacteria UTI of the same age and gender. RESULTS A total of 243 patients with community-acquired UTI in a 5 year period were evaluated, of whom 46% had UTI caused by ESBL bacteria. Seventy-seven cases were matched with 77 controls. There were no significant differences in the clinical presentation between the two groups apart from a longer hospital stay in the ESBL group (9.1 ± 5.5 days vs 8.0 ± 4.4 days, P = 0.013). Significant potential risk factors for ESBL-UTI were previous use of antibiotics in the last 3 months, previous hospitalization in the last 3 months, history of recurrent UTI, and presence of renal anomalies. On logistic regression analysis, history of previous hospitalization in the last 3 months (OR, 3.83; 95%CI: 1.49-9.84) was identified as an independent significant risk factor for ESBL-UTI. There was a significantly higher resistance to amoxicillin-clavulanate, amikacin, gentamycin and quinolones in the ESBL group compared with the control group. CONCLUSION Recognizing the risk factors for ESBL-UTI helps to identify the high-risk cases and enables proper management.

Abstract
Objective: The aim of this study was to determine the clinical outcome, microbiological outcome and safety profile of CSE-1034, a novel combination of Ceftriaxone, Sulbactam and EDTA in patients with complicated urinary tract infections (cUTI). Materials and Methods: This was a randomized, controlled, open-labeled Phase-3 trial with the primary objective of assessing the efficacy and safety of CSE-1034 versus Ceftriaxone for the empirical treatment of cUTI. Adult cUTI patients were randomized to receive either intravenous dose of CSE-1034 or Ceftriaxone. The primary end point was composite cure rate (clinical response and bacterial eradication) in mMITT population at test of cure (TOC) visit. Secondary measures included verification of primary endpoint across other visits in different population sets, safety of patients and treatment duration. Results: Overall, 204 patients were enrolled in the study and received one of the two treatments. At primary endpoint (TOC visit), the composite cure rate was much higher in CSE-1034 treatment arm compared to Ceftriaxone arm i.e. 97% (68/70) vs 83% (58/71) (treatment difference 12.6%; 95% CI: 5.9% to 26.4%). The adverse events (AEs) rates reported in two treatment arms were 21% in CSE-1034 and 36% in Ceftriaxone groups. Additionally, the treatment duration in CSE-1034 arm was significantly less (P < 0.05). Conclusions: CSE-1034 3 g every 24 h showed a high favorable clinical and bacteriological response, and 95% CI around the treatment difference prove the superiority of CSE-1034 vs. Ceftriaxone for the treatment of cUTI. Therefore, CSE-1034 provides an effective alternative in the treatment of patients with cUTI.

Abstract
CONTEXT Antibiotic resistance to uropathogens has grown significantly worldwide. Today, pediatric urologist experience a situation that needs appropriate action because urinary tract infections are one of the most common bacterial infections in children. OBJECTIVE In this overview we aimed at presenting the clinical aspects of antibiotic usage in pediatric urology. Our intention was to take part of the important debate regarding future management of bacterial resistance against antibiotics. EVIDENCE ACQUISITION We searched PubMed for the terms: [UTI in children], [Recurrent UTI in children], and [Antibiotic resistance in UTI]. When using these terms, we found a numerous amount (3875) of published clinical articles related to the topic. By means of an overview, we chose not to focus on a specific condition but to an overall understanding of the problems related to pediatric urology in general. EVIDENCE SYNTHESIS We found that usage of antibiotics has had an unquestionable benefit to reduce the morbidity and mortality related to urinary tract infections in childhood. However, recent studies suggest that early exposure to antibiotics in childhood might have negative systemic effects related to neurocognitive function, body metabolism, and fat distribution. In addition to increased resistance to common antimicrobial agents, it has resulted in increased costs and inadequate effect in severe infections. This calls for changes in the clinical management of urinary pathogens in pediatric urology. CONCLUSIONS As the prevalence of antibiotic resistance grows, pediatric urologists have a key role in managing its consequences and its prevention. PATIENT SUMMARY In this overview we looked at the consequences of antibiotic usage treating urinary tract infections in childhood. We found that the prevalence of antibiotic resistance has grown. We concluded that decision-makers must know about the short- and long-term effects of antibiotic usage in children. When we understand the development of antibiotic resistance better, we can build up prevention strategies.

Abstract
PURPOSE Escherichia coli sequence type (ST) 131, a multidrug-resistant clone causing extraintestinal infections, has rapidly become prevalent worldwide. However, the epidemiological and clinical features of pediatric infections are poorly understood. We aimed to explore the characteristics of ST131 Escherichia coli isolated from Korean children with urinary tract infections. METHODS We examined 114 uropathogenic E. coli (UPEC) isolates from children hospitalized at Chung-Ang University Hospital between 2011 and 2014. Bacterial strains were classified into STs by partial sequencing of seven housekeeping genes (adk, fumC, gyrB, icd, mdh, purA, and recA). Clinical characteristics and antimicrobial susceptibility were compared between ST131 and non-ST131 UPEC isolates. RESULTS Sixteen UPEC isolates (14.0%) were extended-spectrum β-lactamase (ESBL)-producers; 50.0% of ESBL-producers were ST131 isolates. Of all the isolates tested, 13.2% (15 of 114) were classified as ST131. There were no statistically significant associations between ST131 and age, sex, or clinical characteristics, including fever, white blood cell counts in urine and serum, C-reactive protein, radiologic abnormalities, and clinical outcome. However, ST131 isolates showed significantly lower rates of susceptibility to cefazolin (26.7%), cefotaxime (40.0%), cefepime (40.0%), and ciprofloxacin (53.3%) than non-ST131 isolates (65.7%, 91.9%, 92.9%, and 87.9%, respectively; P<0.001 for all). ESBL was more frequently produced in ST131 (53.3%) than in non-ST131 (8.1%) isolates (P<0.01). CONCLUSION ST131 E. coli isolates were prevalent uropathogens in children at a single medical center in Korea between 2011 and 2014. Although ST131 isolates showed higher rates of antimicrobial resistance, clinical presentation and outcomes of patients were similar to those of patients infected with non-ST131 isolates.

Abstract
OBJECTIVES We aimed to evaluate the prevalence of paediatric urinary tract infections (UTIs) caused by extended spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE), identify predisposing factors and examine their effect on the length of hospital stay (LOS). METHODS For this systematic review and meta-analysis, we searched the PubMed and EMBASE databases for studies that provide data on the rate of ESBL-PE among paediatric UTIs. RESULTS Out of 1828 non-duplicate citations, 16 studies reporting a total of 7374 cases of UTI were included. The prevalence of ESBL-PE was 14% [(95%CI 8, 21)]. Vesicoureteral reflux (VUR) [OR = 2.79, (95%CI 1.39, 5.58)], history of UTI [OR = 2.89 (95%CI 1.78, 4.68)] and recent antibiotic use [OR = 3.92, (95%CI 1.76, 8.7)] were identified as risk factors. The LOS was significantly longer among children infected with ESBL-PE, compared to those infected with other uropathogens. [SMD = 0.88, (95%CI 0.40, 1.35)]. CONCLUSIONS In the paediatric population, 1 out of 7 UTIs are caused by ESBL-PE. Patients with VUR, previous UTI or recent antibiotic use constitute a high risk group and these pathogens are associated with increased LOS. The significant incidence of ESBL-PE in this population should be taken into consideration in the development of empiric treatment protocols and antibiotic stewardship programmes, especially in high-prevalence areas.
