Abstract
Urinary tract infections (UTIs) are serious bacterial infections affecting children of all ages. An understanding of the methods of urine collection is important to prevent the contamination of urine specimens and to interpret results. The diagnosis of a UTI requires appropriate interpretation of both urinalysis and urine culture results because testing must indicate evidence of inflammation and the presence of bacteria. Rapid treatment of UTIs is imperative to prevent acute decompensation and systemic illness. Empiric antibiotics should be narrowed as soon as possible to tailor antibiotic treatment and limit antibiotic overuse. Imaging with a renal ultrasound scan is recommended for all infants with first febrile UTIs rather than a voiding cystourethrogram. An additional goal of UTI treatment is to prevent renal scarring, which can lead to lifelong health consequences. Children with anatomic abnormalities of the urinary tract and those who have recurrent UTIs are at increased risk of renal scarring. [Pediatr Ann. 2024;53(6):e217-e222.].

Lactobacillus rhamnosus PL1 and Lactobacillus plantarum PM1 versus Placebo as Prophylaxis for Recurrence of Urinary Tract Infections in Children. Microorganisms 2024; 12:1037.

Abstract
Urinary tract infections (UTIs) rank among the most prevalent bacterial infections in children. Probiotics appear to reduce the risk of recurrence of UTIs. This study aimed to evaluate whether probiotics containing Lactobacillus rhamnosus PL1 and Lactobacillus plantarum PM1 therapy prevent UTIs in the pediatric population compared to a placebo. A superiority, double-blind, randomized, controlled trial was conducted. In total, 54 children aged 3-18 years with recurrent UTIs or ≥one acute pyelonephritis and ≥one risk factor of recurrence of UTIs were randomly assigned (27 patients in each arm) to a 90-day probiotic or placebo arm. The age, sex, diagnosis, renal function, risk factors, and etiology of UTIs did not vary between the groups. During the intervention, 26% of children taking the probiotic had episodes of UTI, and it was not significantly less than in the placebo group. The number of UTI episodes during the intervention and the follow-up period decreased significantly in both groups, but the difference between them was insignificant. We observed a decrease in UTIs during the study of almost 50% in the probiotic group compared to the placebo group. Probiotics can be used as natural, safe prophylaxis for children with risk factors for UTIs in whom antibiotic prevention is not indicated.

Abstract
Despite the American Academy of Pediatrics guidelines for the evaluation, treatment, and management of urinary tract infections (UTIs), UTI diagnosis and management remains challenging for clinicians. Challenges with acute UTI management stem from vague presenting signs and symptoms, diagnostic uncertainty, limitations in laboratory testing, and selecting appropriate antibiotic therapy in an era with increasing rates of antibiotic-resistant uropathogens. Recurrent UTI management remains difficult due to an incomplete understanding of the factors contributing to UTI, when to assess a child with repeated infections for kidney and urinary tract anomalies, and limited prevention strategies. To help reduce these uncertainties, this review provides a comprehensive overview of UTI epidemiology, risk factors, diagnosis, treatment, and prevention strategies that may help pediatricians overcome the challenges associated with acute and recurrent UTI management.

Abstract
A retrospective, cross-sectional study of children with suspected urinary tract infections (UTIs) 3 months to 18 years of age who had a urinalysis and urine culture (UC) during an emergency department (ED) visit between 2019 and 2020 was performed. Chi-square, Fisher exact, and independent samples T tests were used as appropriate. Median age was 6.6 years (interquartile range = 3.3-12.4). Urinalysis positivity was 92.8%, of which 81.9% of children were prescribed a first-line antibiotic. First-line antibiotic use was 82.7%. Positive UC rate was 84.7%, with 84% receiving a first-line antibiotic (P = .025). The correlation between a positive urinalysis and a positive UC was 80.8% (P < .001). Change of antibiotics based on the uropathogen of positive UCs was 6.3% (P < .001). The urinalysis and UC guided the diagnosis and treatment of UTIs. First-line antibiotics can be safely administered in the ED and prescribed for positive urinalyses. Studies are needed to evaluate the discontinuation of antibiotics with negative UCs as part of antibiotic stewardship initiatives.

Abstract
Bacteriuria in paediatric oncology patients have not been well studied. This retrospective study analysed clinical features, distribution and antimicrobial susceptibility of bacterial pathogens cultured from urine in paediatric oncology patients over a 4-year period (2019-2022). A total of 143 episodes of bacteriuria were documented in 74 patients. Neutropenia was present in 17.5% (25/143), symptoms in 25.9% (37/143) and urinary catheter in 7.0% (10/143) episodes. Symptomatic bacteriuria episodes were statistically significantly more frequent in patients with neutropenia (p = 0.0232). The most common bacterial pathogens were Escherichia coli (n = 49; 32.2%), Klebsiella spp. (n = 34; 22.4%), Pseudomonas aeruginosa (n = 22; 14.5%) and Enterococcus spp. (n = 21; 13.8%). Extended-spectrum β-lactamases-producing (ESBL) Enterobacterales were found in 11 episodes (11/143; 7.7%) with the highest proportion among Klebsiella pneumoniae isolates (n = 7/34; 20.6%). No carbapenem-resistant Enterobacterales, multidrug-resistant P. aeruginosa or vancomycin-resistant Enterococcus spp. were found. The most important novelties are demonstrating P. aeruginosa as one of the prominent bacteriuria pathogens in this patient population, presence of ESBL isolates and carbapenem-resistant P. aeruginosa later during hospitalization highlights the need for appropriate antimicrobial treatment. However, because of the small number of symptomatic patients, further studies are needed to clarify the importance of including urine culture in the diagnostic process in patients with febrile neutropenia.

Abstract
Human Ribonuclease (RNase) 6 is a monocyte and macrophage-derived protein with potent antimicrobial activity toward uropathogenic bacteria. The RNASE6 gene is heterogeneous in humans due to the presence of single nucleotide polymorphisms (SNPs). RNASE6 rs1045922 is the most common non-synonymous SNP, resulting in a G to A substitution that determines an arginine (R) to glutamine (Q) transversion at position 66 in the protein sequence. By structural analysis we observed that R66Q substitution significantly reduces the positive electrostatic charge at the protein surface. Here, we generated both recombinant RNase 6-R66 and -Q66 protein variants and determined their antimicrobial activity toward uropathogenic Escherichia coli (UPEC), the most common cause of UTI. We found that the R66 variant, encoded by the major SNP rs1045922 allele, exhibited superior bactericidal activity in comparison to the Q66 variant. The higher bactericidal activity of R66 variant correlated with an increase in the protein lipopolysaccharide binding and bacterial agglutination abilities, while retaining the same enzymatic efficiency. These findings encourage further work to evaluate RNASE6 SNP distribution and its impact in UTI susceptibility.

Abstract
This study investigates the susceptibility of different age groups and genders to urinary tract infections (UTIs) in pediatric populations, focusing on anatomical and behavioural factors. A systematic review of clinical data explores manifestations, accurate diagnosis methods, and antibiotic treatment regimens. Escherichia coli is a prevalent uropathogen, and the study addresses concerns about antibiotic resistance. The research aims to close knowledge gaps, influence guidelines, and enhance public health initiatives. Factors influencing UTI prevalence, such as age, gender, and structural abnormalities, are discussed. The review follows a robust search methodology, presenting a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) flow diagram. The included studies cover a wide range of topics related to pediatric UTIs, including aetiology, treatment, prevention, and diagnostic approaches. The study emphasizes the importance of understanding and addressing pediatric UTIs for effective management and prevention.

Abstract
We aimed to investigate if children with their first UTI and a concomitant positive blood culture have a higher risk of abnormalities. We performed a retrospective study of children younger than 18 years of age with their first UTI. Multivariate logistic regression and receiver operating characteristic (ROC) curves were used to evaluate if positive blood cultures are associated with urinary abnormalities. After the screening process, we considered the enrolled 161 children with UTIs. The median age was three months, and 83 were females (43.2%). In multivariate analysis, age (p = 0.001, 95% CI 1.005-1.020), the presence of Pseudomonas aeruginosa or unusual germs in urine cultures (p = 0.002, 95% CI 2.18-30.36) and the positivity of blood cultures (p = 0.001, 95% CI 2.23-18.98) were significantly associated with urinary abnormalities. A model based on these parameters has an AUC of 0.7168 to predict urinary malformations (p = 0.0315). Conclusions include how greater age, a positive blood culture and the presence of Pseudomonas aeruginosa or unusual germs in urine culture in children hospitalised for their first episode of a UTI are factors associated with a significantly higher risk of urinary abnormalities. These data can guide the implementation of more personalized strategies to screen for urinary abnormalities that may be included in future guidelines.

Abstract
BACKGROUND A first febrile urinary tract infection (UTI) is a common condition in children, and pathways of management have evolved over time. OBJECTIVE To determine the extent to which pediatricians and surgeons differ in their investigation and management of a first febrile UTI, and to evaluate the justifications for any divergence of approach. MATERIALS AND METHODS A literature search was conducted for papers addressing investigation and/or management following a first febrile UTI in children published between 2011 and 2021. Searches were conducted on Medline, Embase, and the Cochrane Controlled Trials Register. To be eligible for inclusion, a paper was required to provide recommendations on one or more of the following: ultrasound (US) and voiding cystourethrogram (VCUG), the need for continuous antibiotic prophylaxis and surgery when vesicoureteral reflux (VUR) was detected. The authorship required at least one pediatrician or surgeon. Authorship was categorized as medical, surgical, or combined. RESULTS Pediatricians advocated less imaging and intervention and were more inclined to adopt a "watchful-waiting" approach, confident that any significant abnormality, grades IV-V VUR in particular, should be detected following a second febrile UTI. In contrast, surgeons were more likely to recommend imaging to detect VUR (p<0.00001), and antibiotic prophylaxis (p<0.001) and/or surgical correction (p=0.004) if it was detected, concerned that any delay in diagnosis and treatment could place the child at risk of kidney damage. Papers with combined authorship displayed intermediate results. CONCLUSION There are two distinct directions in the literature regarding the investigation of an uncomplicated first febrile UTI in a child. In general, when presented with a first febrile UTI in a child, physicians recommend fewer investigations and less treatment, in contrast to surgeons who advocate extensive investigation and aggressive intervention in the event that imaging detects an abnormality. This has the potential to confuse the carers of affected children.

Abstract
BACKGROUND Ureteral reimplantation remains the primary surgical method used for patients with vesicoureteral reflux (VUR). Cystoscopy is commonly performed first to visualize anatomy and rule out possible abnormalities. Urine cultures may also be obtained. The objective of this study is to evaluate the prudency of preoperative urine cultures and cystoscopies in pediatric patients undergoing ureteral reimplantation. METHODS Pediatric urologists were surveyed regarding collecting urine cultures in asymptomatic patients and cystoscopies before reimplantation. A retrospective review was also conducted of patients who underwent ureteral reimplantation for VUR between March 2018 and April 2021 at Cook Children's Medical Center. RESULTS When physicians were asked the frequency they obtain urine cultures before reimplantation on asymptomatic patients, 36% said "never" and 38% said "always." Regarding cystoscopy, 53% said "never" and 32% said "always." Inclusion criteria were met by 101 patients. Cystoscopies were performed in 46 patients and never altered the reimplantation. There were 20 preoperative, 90 intraoperative, and 61 postoperative urine cultures. Complications were associated with positive cultures of urine collected intraoperatively and postoperatively only. CONCLUSION Cystoscopies and asymptomatic urine cultures obtained before ureteral reimplantation provide no additional benefit while increasing cost for patients' families. Further research is needed to thoroughly identify the prudency of such practices in ureteral reimplantation for VUR.

Pediatr Nephrol 2023; 38:3337-3346.

Abstract
BACKGROUND To determine whether urine neutrophil gelatinase-associated lipocalin (uNGAL) might be superior to pyuria for detecting urinary tract infection (UTI) regardless of urine specific gravity (SG) in young children. METHODS We conducted a retrospective analysis of children aged < 3 years who were evaluated for UTI with urinalysis, urine culture, and uNGAL measurements during a 5-year period. Sensitivity, specificity, likelihood ratios (LRs), predictive values (PVs), area under the curves (AUCs) of uNGAL cut-off levels, and various microscopic pyuria thresholds for detecting UTI were calculated for dilute (SG < 1.015) and concentrated urine (SG ≥ 1.015). RESULTS Of 456 children included, 218 had UTI. The diagnostic value of urine white blood cell (WBC) concentration to define UTI changed with urine SG. For detecting UTI, uNGAL cut-off of 68.4 ng/mL had higher AUC values than pyuria ≥ 5 WBCs/high power field (HPF) for dilute and concentrated urine samples (both P < 0.05). Positive LR and PV and specificity of uNGAL were all greater than those of pyuria ≥ 5 WBCs/HPF regardless of urine SG, although the sensitivity of pyuria ≥ 5 WBCs/HPF was higher than that of uNGAL cut-off for dilute urine (93.8% vs. 83.5%) (P < 0.05). At uNGAL ≥ 68.4 ng/mL and ≥ 5 WBCs/HPF, posttest probabilities of UTI were 68.8% and 57.5% for dilute urine and 73.4% and 57.3% for concentrated urine, respectively. CONCLUSIONS Urine SG can affect the diagnostic performance of pyuria for detecting UTI and uNGAL might be helpful for identifying UTI regardless of urine SG in young children.

Zhou Y, Zhou Z, Zheng L, Gong Z, Li Y, Jin Y, Huang Y, Chi M. Urinary Tract Infections Caused by Uropathogenic Escherichia coli: Mechanisms of Infection and Treatment Options. Int J Mol Sci 2023; 24:10537. [PMID: 37445714 DOI: 10.3390/ijms241310537] [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: 05/24/2023] [Revised: 06/20/2023] [Accepted: 06/21/2023] [Indexed: 07/15/2023] Open
Abstract
Urinary tract infections (UTIs) are common bacterial infections that represent a severe public health problem. They are often caused by Escherichia coli (E. coli), Klebsiella pneumoniae (K. pneumonia), Proteus mirabilis (P. mirabilis), Enterococcus faecalis (E. faecalis), and Staphylococcus saprophyticus (S. saprophyticus). Among these, uropathogenic E. coli (UPEC) are the most common causative agent in both uncomplicated and complicated UTIs. The adaptive evolution of UPEC has been observed in several ways, including changes in colonization, attachment, invasion, and intracellular replication to invade the urothelium and survive intracellularly. While antibiotic therapy has historically been very successful in controlling UTIs, high recurrence rates and increasing antimicrobial resistance among uropathogens threaten to greatly reduce the efficacy of these treatments. Furthermore, the gradual global emergence of multidrug-resistant UPEC has highlighted the need to further explore its pathogenesis and seek alternative therapeutic and preventative strategies. Therefore, a thorough understanding of the clinical status and pathogenesis of UTIs and the advantages and disadvantages of antibiotics as a conventional treatment option could spark a surge in the search for alternative treatment options, especially vaccines and medicinal plants. Such options targeting multiple pathogenic mechanisms of UPEC are expected to be a focus of UTI management in the future to help combat antibiotic resistance.

Abstract
The emergence of multi-drug-resistant Klebsiella pneumoniae (Kp) strains constitutes an enormous threat to global health as multi-drug resistance-associated treatment failure causes high mortality rates in nosocomial infections. Rapid pathogen detection and antibiotic resistance screening are therefore crucial for successful therapy and thus patient survival. Reporter phage-based diagnostics offer a way to speed up pathogen identification and resistance testing as integration of reporter genes into highly specific phages allows real-time detection of phage replication and thus living host cells. Kp-specific phages use the host's capsule, a major virulence factor of Kp, as a receptor for adsorption. To date, 80 different Kp capsule types (K-serotypes) have been described with predominant capsule types varying between different countries and continents. Therefore, reporter phages need to be customized according to the locally prevailing variants. Recently, we described the autographivirus vB_KpP_TUN1 (TUN1), which specifically infects Kp K64 strains, the most predominant capsule type at the military hospital in Tunis (MHT) that is also associated with high mortality rates. In this work, we developed the highly specific recombinant reporter phage rTUN1::nLuc, which produces nanoluciferase (nLuc) upon host infection and thus enables rapid detection of Kp K64 cells in clinical matrices such as blood and urine. At the same time, rTUN1::nLuc allows for rapid antibiotic susceptibility testing and therefore identification of suitable antibiotic treatment in less than 3 h.

Abstract
BACKGROUND Urinary tract infection (UTI) in children is one of the commonest bacterial infections seen in the pediatric population. Clinical presentation ranges from fever with or without focus and isolation of microbiological agents streamline the treatment. Moreover, local/regional microbial profiles are helpful in antibiotic selection, we conducted a study to assess the prevalence of urine culture positivity in a suspected case of UTI. In addition, antibiotic susceptibility patterns and ultrasonography (USG) finding in culture-positive patients were also studied. METHODS AND MATERIALS It is a prospective observational study comprising symptomatic children aged one month to 18 years presenting to the outpatient department (OPD), inpatient department (IPD), and the emergency department of Pediatrics with UTI during the period of September 2019 to September 2020. The recorded variables were demographic, clinical presentation, anthropometry, physical examination, blood biochemistry, and outcome. Urine samples were collected and processed as per standard protocols. USG was done for all culture-positive children. Data were presented as frequency, mean (SD) and parametric and non-parametric data were analyzed by Wilcoxon-Mann-Whitney U Test, Chi-Squared Test, or Fisher's Exact Test. Results: Of the total 354 children, 202 (57.1%) were male and the prevalence of UTI was 64 (18.1%). E. coli (70.3%) was the commonest isolated organism followed by Klebsiella spp (15.6%) and Pseudomonas spp (7%) respectively. The mean (SD) age (months) of presentation of symptoms was significantly lower in culture-positive children as compared to [ 83.49 (58.96) vs 110.10 (58.60); p=0.001] culture-negative children. Fever (96.6%) followed by dysuria (20.1%) were the most common symptoms presented for UTI however dysuria (p=0.003), pus cells (p<0.0001), and RBCs (p=0.002) were significantly present in culture positive children. This study shows increased resistance to third generation of cephalosporins. This study revealed significant differences among various groups (organism growth in positive culture) and the Antibiotic susceptibility test (AST) with a p-value of <0.001. Conclusion: The prevalence of culture-positive UTI was similar to the reported literature and the presence of fever, dysuria, pus cells, and RBC in urine were commonly observed in the lower age group. Amikacin can be used in suspected UTIs with cephalosporin as empirical antibiotics in the Himalayan Foothills region.

Abstract
Background Proteus mirabilis is one of the pathogens commonly causing urinary tract infections (UTIs). The molybdate-binding protein ModA encoded by modA binds molybdate with high affinity and transports it. Increasing evidence shows that ModA promotes the survival of bacteria in anaerobic environments and participates in bacterial virulence by obtaining molybdenum. However, the role of ModA in the pathogenesis of P. mirabilis remains unknown. Results In this study, a series of phenotypic assays and transcriptomic analyses were used to study the role of ModA in the UTIs induced by P. mirabilis. Our data showed that ModA absorbed molybdate with high affinity and incorporated it into molybdopterin, thus affecting the anaerobic growth of P. mirabilis. Loss of ModA enhanced bacterial swarming and swimming and up-regulated the expression of multiple genes in flagellar assembly pathway. The loss of ModA also resulted in decreased biofilm formation under anaerobic growth conditions. The modA mutant significantly inhibited bacterial adhesion and invasion to urinary tract epithelial cells and down-regulated the expression of multiple genes associated with pilus assembly. Those alterations were not due to anaerobic growth defects. In addition, the decreased bacteria in the bladder tissue, the weakened inflammatory damage, the low level of IL-6, and minor weight change was observed in the UTI mouse model infected with modA mutant. Conclusion Here, we reported that in P. mirabilis, ModA mediated the transport of molybdate, thereby affecting the activity of nitrate reductase and thus affecting the growth of bacteria under anaerobic conditions. Overall, this study clarified the indirect role of ModA in the anaerobic growth, motility, biofilm formation, and pathogenicity of P. mirabilis and its possible pathway, and emphasized the importance of the molybdate-binding protein ModA to P. mirabilis in mediating molybdate uptake, allowing the bacterium to adapt to complex environmental conditions and cause UTIs. Our results provided valuable information on the pathogenesis of ModA-induced P. mirabilis UTIs and may facilitate the development of new treatment strategies.

Abstract
BACKGROUND To compare the epidemiologic, microbiologic and imaging characteristics of urinary tract infections (UTI) in children <2 years of age with and without anatomic urinary tract abnormalities (AA). METHODS All children hospitalized with UTI during 1.1.2005-31.12.2018 were included. The study group (patients with AA) included 76 patients. The control group (99 patients) included patients without AA. RESULTS 1163 children were hospitalized. Age at diagnosis was younger in the study group vs. controls (5.2 ± 6.0 vs. 7.9 ± 7.5 months, P = 0.038). Uropathogens distribution was different (P = 0.007), with lower Escherichia coli (Ec) and Proteus mirabilis (Pm) percentages in the study group and higher percentages of Enterococcus spp. (Ent) in controls. In the study group, Ec nonsusceptibility rates to ampicillin, amoxicillin/clavulanic acid, cefazolin, cefuroxime, TMP/SMX and ceftriaxone were 58%, 40%, 14%, 14%, 12% and 10%, respectively, with no differences vs. controls. Ultrasound (US) was performed in 69/76 (98%) patients with AA (84.1%, abnormal); bilateral (39.7%) and unilateral (32.7%) ureteral dilatation were the most frequent findings. Voiding cystourethrography was performed in 46 patients (pathologic in 35, 76%); 31 (81.6%) patients had vesicoureteral reflux (VUR) (bilateral in 11, 35.5%; grade 4/5 in 7 patients). Uropathogens distribution in VUR patients differed between study and control groups, with lower Ec and Pm in the first group and higher Pseudomonas aeruginosa and Ent percentages in the control group. CONCLUSION Age at diagnosis was lower and pathogen distribution was different in patients with AA. Antibiotic susceptibility patterns of the main uropathogens were similar between patients with or without AA.

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
OBJECTIVE To describe geographic and sociodemographic variations in operating hours and availability of medications commonly prescribed by pediatric urologists at Washington State retail pharmacies. METHODS We identified all retail pharmacies in the state. We stratified counties by population density and household income (HI) and compared differences in pharmacy operating hours and availability of 10 commonly prescribed medications. RESULTS 1057/1058 pharmacies were contacted. All pharmacies had liquid formulations of oxycodone, hydrocodone, ibuprofen, acetaminophen, amoxicillin, and trimethoprim-sulfamethoxazole in stock. Liquid formulations of ciprofloxacin (10%) and oxybutynin (14.3%) were uncommonly stocked, while 92.5% of pharmacies stocked nitrofurantoin suspension, and 80.9% nitrofurantoin capsules. Statewide, 108 (10.2%) of pharmacies were closed on Saturdays and 297 (28.1%) closed on Sunday. More high (HPDC) than low population density (LPDC) (62.5% vs 0%, P < .001) and high-HI than low-HI counties (62.5% vs 0%, P = .30) had 24-hour pharmacies. A larger proportion of pharmacies were open 7-days in HPDC than LPDC (75.6% vs 56.2%, P < .0001) and in high-HI than low-HI counties (100% vs 62.5%, P = .30). The likelihood of a pharmacy being open 7 days/week was significantly higher in HPDC (vs LPDC; OR = 13.2, 95% CI: 4.39-39.7) and high-HI (vs low-HI; OR = 4.98, 95% CI: 2.58-9.60) counties. CONCLUSION Most pharmacies in Washington State carry medications commonly prescribed by pediatric urologists. However, retail pharmacy operating hours are widely variable and create geographic and temporal barriers in rural and poor areas that may limit the timely administration of prescription medication. Providers should consider a patient's practical ability to fill a prescription when starting a time-sensitive medication.

Abstract
Ribonuclease 7 (RNase 7) is an antimicrobial peptide that prevents urinary tract infections (UTI); however, it is yet unknown how RNASE7 genetic variations affect its antimicrobial activity and its mitigation of UTI risk. This study determined whether the RNASE7 SNP rs1263872 is more prevalent in children with UTI and defined how rs1263872 affects RNase 7's antimicrobial activity against uropathogenic E. coli (UPEC). We performed genotyping for rs1263872 in 2 national UTI cohorts, including children enrolled in the Randomized Intervention for Children with Vesicoureteral Reflux trial or the Careful Urinary Tract Infection Evaluation study. Genotypes from these cohorts were compared with those of female controls with no UTI. To assess whether rs1263872 affects RNase 7's antimicrobial activity, we generated RNase 7 peptides and genetically modified urothelial cultures encoding wild-type RNase 7 and its variant. Compared with controls, girls in both UTI cohorts had an increased prevalence of the RNASE7 variant. Compared with the missense variant, wild-type RNase 7 peptide showed greater bactericidal activity against UPEC. Wild-type RNase 7 overexpression in human urothelial cultures reduced UPEC invasive infection compared with mutant overexpression. These results show that children with UTI have an increased prevalence of RNASE7 rs1263872, which may increase UTI susceptibility by suppressing RNase 7's antibacterial activity.

Abstract
Background: The prevalence and risk factors of urinary tract infection (UTI) in neonates with unexplained hyperbilirubinemia are not studied thoroughly. Since the prevalence of UTI is highly variable in different areas and countries, this study aimed to review the existing data of Iranian neonates with UTI presented with unexplained hyperbilirubinemia. Methods: This study is a meta-analysis of Iranian newborns with unexplained hyperbilirubinemia. We identified all studies indexed in international (Web of Science, PubMed, Scopus, Google Scholar) and national (Science Information Database, Magiran) databases from 2000–2018. Search terms included: Urinary Tract Infections OR UTI AND urine OR culture OR microbio, jaundice OR icter OR hyperbili, AND Iran. Results: Overall, 4210 neonates from 17 studies were included. The pooled prevalence of UTI in neonates with unexplained hyperbilirubinemia was 6.81% (95% CI: 4.86–8.77). Considering the subgroups analyses; the prevalence of UTI was higher in the prolonged vs. not-prolonged state (8.34% vs. 4.00%), low birth weight vs. normal birth weight (7.81% vs. 4.51%), and exclusive vs. non-exclusive breastfeeding (8.84% vs. 4.72%). Male gender and low birth weight increased the risk of UTI about two times compared to the female gender and normal birth weight, respectively. The results of the analyses in neonates with unconjugated hyperbilirubinemia also showed the above-mentioned subgroup differences. Conclusion: Due to considerable prevalence of UTI in neonates with unexplained hyperbilirubinemia and risk factors in this age group, investigation for UTI is essential for the workup in this situation.

Abstract
LUTD is one of the possible factors influencing pediatric kidney graft outcomes. This study evaluates the results of a thorough assessment of voiding behavior in pediatric transplants. Data of patients with kidney disease of nephrological origin are compared to those with urological origin. A single-center analysis of pediatric kidney transplants performed from 2005 to the present was executed. Donor and recipient characteristics as well as voiding and drinking habits were documented using FVCs and uroflowmetry with PVR measurements. LUTD was defined by a mean MVV >150% or <65% of the EBC for age, abnormal uroflowmetry, PVR repeatedly >15% of EBC or >20 mL, abnormal voiding patterns or behavior, and presence of LUT symptoms. LUTD was diagnosed in 71% of the 56 screened children and more present in urological origin of kidney disease (100%) compared to nephrological origin (61%, P = .005). Individual presence of LUT symptoms, abnormal voiding behavior, FVC parameters, UTIs, and uroflowmetry/PVR parameters were not different between the two groups. Polyuria after transplantation was seen in 63% of patients, mainly in the first post-transplant years and recipients aged <10 years. Time after transplantation was a significant independent predictive factor for the presence of LUTD. LUTD is common in all pediatric kidney recipients and underestimated in those with a nephrological origin of disease. Active screening, monitoring and a care attention plan prior to transplantation and during follow-up, is advocated to optimize outcomes for all patients.

Abstract
AIM Urinary tract infection is a common cause of paediatric morbidity. However, there is no consensus on the default method for urine culture collection in children. This study aimed to examine the contamination rates of different urine collection methods. METHODS This was a retrospective cohort study in a paediatric emergency department. Data were collected from electronic health records on all children whose urine culture samples were obtained in the paediatric emergency department between March 2018 and March 2019. Different methods of urine collection included the midstream (MS) method, clean catch (CC), transurethral bladder catheterisation and suprapubic aspiration. Contamination rates and positive urine culture rates were calculated and compared for sex, age, and collection method. RESULTS Urine culture samples were collected from 1507 children. There were 284 (18.8%) cultures that were positive with significant growth and 52 (3.5%) that were defined as 'contaminated'. The contamination rates for the midstream method in toilet-trained children were 1.6% (10/609), 4.9% (17/348) for CC in pre-continent children, 4.9% (25/515) for transurethral bladder catheterisation and 0% (0/35) (P = 0.006) for suprapubic aspiration. There was no significant difference in contamination rates of urine cultures collected by CC and catheterisation in the compared groups. The rates of positive cultures in the subgroup of children with high suspicion for Urinary tract infection were also found to be similar. CONCLUSIONS Our study shows that CC is non-inferior to catheterisation for collecting urine cultures in young children.

Three-Year Trend in Escherichia coli Antimicrobial Resistance among Children's Urine Cultures in an Italian Metropolitan Area. CHILDREN-BASEL 2021; 8:children8070597. [PMID: 34356576 PMCID: PMC8303248 DOI: 10.3390/children8070597] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Revised: 07/10/2021] [Accepted: 07/13/2021] [Indexed: 11/17/2022]
Abstract
Urinary tract infections (UTIs) are among the most common bacterial infections in children, and Escherichia coli is the main pathogen responsible. Several guidelines, including the recently updated Italian guidelines, recommend amoxicillin-clavulanic acid (AMC) as a first-line antibiotic therapy in children with febrile UTIs. Given the current increasing rates of antibiotic resistance worldwide, this study aimed to investigate the three-year trend in the resistance rate of E. coli isolated from pediatric urine cultures (UCs) in a metropolitan area of northern Italy. We conducted a retrospective review of E. coli-positive, non-repetitive UCs collected in children aged from 1 month to 14 years, regardless of a diagnosis of UTI, catheter colonization, urine contamination, or asymptomatic bacteriuria. During the study period, the rate of resistance to AMC significantly increased from 17.6% to 40.2% (p < 0.001). Ciprofloxacin doubled its resistance rate from 9.1% to 16.3% (p = 0.007). The prevalence of multidrug-resistant E. coli rose from 3.9% to 9.2% (p = 0.015). The rate of resistance to other considered antibiotics remained stable, as did the prevalence of extended spectrum beta-lactamases and extensively resistant E. coli among isolates. These findings call into question the use of AMC as a first-line therapy for pediatric UTIs in our population, despite the indications of recent Italian guidelines.

Abstract
BACKGROUND Neutrophil gelatinase-associated lipocalin (NGAL) has emerged as a valuable biomarker of urinary tract infection (UTI) in children. PURPOSE This study aimed to compare the diagnostic accuracy of urinary NGAL (uNGAL) with those of serum C-reactive protein (CRP) and white blood cell (WBC) count for predicting UTI and acute pyelonephritis (APN) in febrile children. METHODS The medical charts of children undergoing uNGAL measurements between November 2017 and August 2019 were retrospectively reviewed. Patients with a suspected or diagnosed UTIs were included. The diagnostic accuracies of uNGAL, serum CRP, and WBC count for detecting UTI and APN were investigated. Independent predictors of UTI and APN were investigated using multivariable logistic regression analyses. RESULTS A total of 321 children were enrolled in this study. The uNGAL levels were higher in the UTI group (n=157) than in the non-UTI group (n=164) (P<0.05). Among children with a UTI, uNGAL levels were higher in the APN group (n=70) than, the non-APN group (n=87) (P<0.05). In the multivariate analysis, uNGAL was independently associated with UTI and APN (both P<0.05). Serum CRP and WBC count were not correlated with the presence of UTI and APN. Receiver operating curve analyses showed that the uNGAL level had the highest area under the curve (AUC) for predicting UTI and APN, respectively (AUC, uNGAL vs. CRP vs. WBC count, 0.860 vs. 0.608 vs. 0.669 for UTI; 0.780 vs. 0.680 vs. 0.639 for APN, all P<0.05, respectively). The predictive values and likelihood ratios of uNGAL were superior to those of serum CRP and WBC count for detecting UTI and APN at each cutoff level. CONCLUSION UNGAL may be more useful than serum CRP and WBC count for identifying and assessing UTI in febrile children.

Abstract
Urinary tract infections (UTIs) are a major public health concern in both community and hospital settings worldwide. Uropathogenic Escherichia coli (UPEC) is the main causative agent of UTI and increasingly associated with antibiotic resistance. Herein, we report the draft genome sequence of 9 fluoroquinolone-resistant UPEC isolates from Brazil and examine selected major phenotypic features, such as antimicrobial resistance profile, phylogroup, serotype, sequence type (ST), virulence genes, and resistance marks. Besides the quinolone resistance, beta-lactams, ESBL production, aminoglycosides, and tetracycline resistance were observed. High prevalence of 20 virulence genes was detected in all isolates, such as those encoding type 1 fimbriae, acid tolerance system, and hemolysin E, particularly within E. coli B2 phylogroup, as ST131 and ST1193 strains, among other genomic analyses as genomic islands, resistance plasmids, and integron identification.

Abstract
INTRODUCTION Urinary tract infection is the second most common bacterial infection in children, after respiratory tract infection. The objective of this work was to study the bacterial ecology and antibiotic susceptibility of germs isolated during childhood urinary tract infections at the Paediatric University Hospital Charles-de-Gaulle in Ouagadougou. PATIENTS AND METHOD This was a descriptive retrospective study covering the period from July 1st, 2010 to June 30, 2015, including 141 children from 0 to 15 years old hospitalized in the medical paediatrics department for a urinary tract infection. RESULTS The hospital frequency of urinary tract infection was 0.7%. The mean age of the patients was 43.1 months. Female patients accounted for 57.4%, a sex-ratio of 0.7. Gram-negative bacilli were often involved (67.4%) with Escherichia Coli and Klebsiella in 35.5% and 22% of cases respectively. The main Gram-positive bacteria were staphylococci (15.5%), enterococci (11.3%) and streptococci (5.6%). Enterobacteriaceae isolated were sensitive to netilmicin (80%), chloramphenicol (76.4%), and furan (82.6%). All strains of staphylococcus were susceptible to furan, gentamicin, chloramphenicol and cefixime. In 66.7% of cases, the isolated strains of staphylococcus were resistant to amoxicillin. CONCLUSION Urinary tract infection is a common problem in pediatrics. Its management must be early and adequate based on knowledge of the bacterial ecology in order to reduce the risk of long-term renal complications.

Abstract
One of the most frequent bacterial infections in children are urinary tract infections (UTIs). In recent years, an increasing incidence of UTIs caused by resistant bacterial strains has been observed, especially with extended-spectrum β-lactamase-producing Enterobacteriaceae that represent about 15% of UTIs. A retrospective study was performed comprising 331 pediatric cases with UTI. Our study aimed to detect the resistance of the uropathogens to common drugs used in UTI treatment. High resistance rates have been recorded for ampicillin, amoxicillin, trimethoprim/sulfamethoxazole (TMP/SMX), cefuroxime, and ciprofloxacin, among E. coli and Klebsiella. The multidrug-resistance (MDR) rate was detected in one-third of the uropathogens, among which more than half were isolated in patients with urinary tract abnormalities. Our study highlighted that nitrofurantoin, ceftriaxone, amikacin and carbapenem may be used for the empirical treatment for febrile or complicated UTI in children. This is the first comprehensive study that evaluates antibiotic resistance in UTIs in children, and their association with urinary tract abnormalities in Romania. As a result of this research, the protocol for initial empiric treatment of infants with febrile or complicated UTI should be modified considering a detailed and ongoing monitoring of local sensitivity of uropathogens to antimicrobial agents.

Abstract
Urinary tract infections (UTIs) are a very widespread infection that can occur in disparate age range, in both sexes and in pregnancy/menopause state. Treatment of UTIs is difficult due to the emergence of antibiotic-resistant bacterial strains. The present study shows five years of data collected on patients admitted at the University Hospital "San Giovann di Dio e Ruggi d'Aragona" in Salerno, Italy. The investigation exhibits the incidence of the infection, of the gender, and of the age group affected, identifying the most representative bacteria involved, drawing their profile of antimicrobial resistance. Bacterial identification and antibiotic susceptibility testing were performed using the VITEK 2 system. Among the 46382 studied patients, 9896 (21.34%) and 36486 (78.66%) were positive and negative for microorganism growth, respectively. Of 9896 positive patients, 6158 (62.23%) females and 3738 (37.77%) males were identified. The highest incidence of positive subjects (56.66%) was recorded in the elderly (>61 years). 8431 (85.20%) uropathogens were Gram-negative, 1367 (13.81%) were Gram-positive, and 98 (0.99%) were Candida species (Candida spp.). Escherichia coli (E. coli) and Enterococcus faecalis (E. faecalis) were the most representative Gram-negative and Gram-positive strains, respectively. The Gram-negative bacteria most representative were highly resistant to ampicillin, whereas among the Gram-positive bacteria, E. faecalis was highly resistant to gentamicin and streptomycin high level synergy, and Enterococcus faecium (E. faecium) to ampicillin, ampicillin/sulbactam, and imipenem. This retrospective work investigates the local epidemiological trend in our university hospital in order to induce an increasingly targeted empirical therapeutic approach for the treatment of UTIs.

Abstract
OBJECTIVE This study aimed to review results of urinalysis with flow cytometry technique at the time of diagnosis of urinary tact infection (UTI), and to determine uropathogenes with their antibiotic resistance patterns in children with first-time UTI. MATERIAL AND METHODS This single-centered, retrospective, cross-sectional study was conducted from January 2015 to December 2017. The study included 361 children with a first-time UTI diagnosis. Age, gender, results of automated urinalysis, urine culture results were recorded. RESULTS Mean ages of children were 55.8±50.7 months. E. coli was the most common isolated microorganism followed by K. pneumoniae, Proteus, Enterococcus, and P. aeroginosa. Median count of pyuria was 44 leukocyte/mm3 (range:0-2954/mm3). Median count of pyuria in female and male patients were 53 and 22 leukocyte/mm3, respectively (p=0047). A total of 98 patients (27.1%) had no pyuria. Proportion of pyuria in female and male patients were 81.2% and 76%, respectively (p>0.05). Mean age of patients with and without pyuria were 59±52 months and 46±44months, respectively (p<0.05). According to uropathogen, there was pyuria at the ratio of 60% in Pseudomonas, 62.5% in Enterococcus spp, 66.7% in Proteus, 78.3% in Klebsiella, and 82.7% in E. coli. Children with UTI induced by E. coli had resistance ratios of 30.5% and 22.4% to cefixime and ceftiaxone, respectively. Children with UTI by Klebsiella spp had resistance ratios of 47.8% and 39.1% to cefixime and ceftriaxone, respectively. CONCLUSION E. coli was the most common uropathogen in children with first-time UTI. Pyuria may be lacking according to age, gender, and type of uropathogene. Pyuria level was higher in females. In addition, ceftriaxone and cefixime resistance is increasing making ampirical treatment choices limited.

Abstract
BACKGROUND To examine the epidemiologic and microbiologic characteristics of first and recurrent UTI in young infants. METHODS A retrospective study of all infants <1 year hospitalized during 2014-2017 with their first UTI and followed during their first year of life. RESULTS 191 infants were enrolled; 69 (36.12%) patients were <2 months and 32 (16.8%) developed R-UTI during the follow-up. The five most common uropathogens were Escherichia coli, Klebsiella spp., Enterococcus spp., Proteus mirabilis and Staphylococcus aureus. High resistance rates were recorded for ampicillin, amoxicillin/clavulanic acid, TMP/SMX, cefuroxime, ceftriaxone, piperacillin/tazobactam and gentamicin among E. coli and Klebsiella spp.; 29.15% E. coli and 42.9% Klebsiella spp. were ESBL-positive. 53.2% of recurrent UTI (R-UTI) episodes were diagnosed within 2 months after the initial UTI episode. E. coli (40.6%) and Klebsiella spp. (37.55) were the most frequent R-UTI pathogens. Twenty-five (78.1%) R-UTIs were caused by recurrent uropathogens representing new infections. Antibiotic resistance rates at recurrence were similar to those at initial UTI, except for a significant increase in E. coli and Klebsiella spp. resistance to piperacillin/tazobactam. CONCLUSION We reported high antibiotic resistance rates to major antibiotic classes used in UTI treatment. Most R-UTI episodes were caused by uropathogens different than those isolated at the initial UTI episode and were caused by highly-resistant organisms. Our findings require frequent monitoring and possible modification of the empiric and prophylactic antibiotic therapy protocols in use. As a result of our findings, the protocol for initial empiric treatment of infants with suspicion of UTI was modified by changing gentamicin to amikacin in the treatment of infants <2 months of life and amikacin monotherapy (intravenous or intramuscular) was introduced as first-line therapy for infants >2 months of life.

Abstract
BACKGROUND Graft survival in pediatric kidney transplant recipients has increased in the last decades. Determining prognostic factors for graft function over time allows the identification of patients at risk for graft loss and could lead to improvement of current guidelines. METHODS Data were collected among pediatric kidney transplant recipients in a single center during the first 5 years after transplantation. Mixed model analysis was used to indicate possible prognostic factors for the loss of graft function. RESULTS A total of 100 pediatric kidney transplant recipients were analyzed. Negative prognostics of graft function are higher donor age and higher recipient age, presence of obstructive uropathology, re-transplant, and occurrence of BK viremia. The negative influence on graft function of both donor age and presence of obstructive uropathology increased over time. In this study, the factors that did not influence graft function over time were the number of HLA mismatches, pre-transplant dialysis, intra-abdominal graft placement, ischemia time, occurrence of acute rejection, presence of lower urinary tract dysfunction, occurrence of urinary tract infections, and infections with cytomegalovirus and Epstein-Barr virus. CONCLUSIONS This study showed that a higher donor age and higher recipient age, presence of obstructive uropathology, a re-transplant, and the occurrence of BK viremia were negative prognostic factors of graft function over time, in the first 5 years after transplant. Graft function was comparable between steroid-sparing regimens (preferable in low-risk patients) and regimens including steroids (for special reasons).

Abstract
Background: Leptin is a hormone that plays an important role in human health against infections. Some studies have reported that leptin acts as a reactant phase marker in some infectious diseases. The role of leptin in febrile urinary tract infection (UTI) has not been adequately evaluated. Objectives: This study was conducted to determine the role of serum leptin in febrile UTI in children. Methods: Thirty-nine febrile UTI patients were compared with 40 healthy children for the serum leptin level. Serum leptin was measured by the enzyme-linked immunosorbent assay method. The results were compared between the groups. Results: Median (IQR) of serum leptin in the case and control groups was 2 ng/mL and 0.6 ng/mL, respectively. A significant difference was observed between the groups in the serum leptin level (P = 0.001). No significant difference was observed between cystitis and acute pyelonephritis patients in the serum leptin level. The correlation analysis showed no significant association between the serum leptin level and acute-phase reactant markers such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) (r = -0.13 and P = 0.41; r = -0.15 and P = 0.36, respectively). Conclusions: The present study showed that although serum leptin increases in febrile UTI, this increase is not correlated with C-reactive protein and erythrocyte sedimentation rate. Also, this marker cannot discriminate between cystitis and acute pyelonephritis.

Abstract
BACKGROUND Increased understanding of characteristics of urinary tract infection (UTI) among very low birthweight infants (VLBW) might lead to improvement in detection and treatment. Continuous monitoring for abnormal heart rate characteristics (HRC) could provide early warning of UTIs. OBJECTIVE Describe the characteristics of UTI, including HRC, in VLBW infants. METHODS We reviewed records of VLBW infants admitted from 2005-2010 at two academic centers participating in a randomized clinical trial of HRC monitoring. Results of all urine cultures, renal ultrasounds (RUS), and voiding cystourethrograms (VCUG) were assessed. Change in the HRC index was analyzed before and after UTI. RESULTS Of 823 VLBW infants (27.7±2.9 weeks GA, 53% male), 378 had > / = 1 urine culture obtained. A UTI (≥10,000 CFU and >five days of antibiotics) was diagnosed in 80 infants, (10% prevalence, mean GA 25.8±2.0 weeks, 76% male). Prophylactic antibiotics were administered to 29 (36%) infants after UTI, of whom four (14%) had another UTI. Recurrent UTI also occurred in 7/51 (14%) of infants not on uroprophylaxis after their first UTI. RUS was performed after UTI in 78%, and hydronephrosis and other major anomalies were found in 19%. A VCUG was performed in 48% of infants and 18% demonstrated vesicoureteral reflux (VUR). The mean HRC rose and fell significantly in the two days before and after diagnosis of UTI. CONCLUSIONS UTI was diagnosed in 10% of VLBW infants, and the HRC index increased prior to diagnosis, suggesting that continuous HRC monitoring in the NICU might allow earlier diagnosis and treatment of UTI.

Abstract
INTRODUCTION Urinary tract infections (UTIs) are usual diseases caused by different strains of microorganisms. Many antibiotics have been applied for the treatment of these infections. However, the development of multidrug-resistant strains is a major problem in these treatments. As alternative complementary agents, several medicinal plants are often used to prevent and/or treat these diseases. AREAS COVERED This review summarized the current evidence about the efficacy of medicinal plants' consumption to prevent and/or co-treat UTIs. The most precise scientific databases, e.g. Medline, Scopus, and Web of Science were comprehensively searched, using relative keywords to identify the relative in vivo and ex vivo animal and human studies. EXPERT OPINION Current studies supported evidence for potential benefit overall concerning medicinal plants' consumption against UTIs by preventing bacterial adherence and inhibiting inflammation cascades through responding immunologically to bacteria invasion. However, most of the current evidence have been focused on in vivo and ex vivo animal studies, while human studies are currently limited and did not focus on a specific medicinal plant. Thus, well-designed clinical trials for long study periods focused on individual medicinal plants are intensely recommended to delineate their effectiveness on the prevention and/or co-treatment of UTIs.

Abstract
Suspected neonatal sepsis is one of the most common diagnoses made in newborns (NBs), but very few NBs actually have sepsis. There is no international consensus to clearly define suspected neonatal sepsis, but each time that this suspected diagnosis is assumed, blood samples are taken, venous accesses are used to administer antibiotics, and the mother-child pair is separated, with prolonged hospital stays. X-rays, urine samples, and a lumbar puncture are sometimes taken. This is of concern, as generally <10% and no more than 25%-30% of the NBs in whom sepsis is suspected have proven neonatal sepsis. It seems easy to start antibiotics with suspicion of sepsis, but stopping them is difficult, although there is little or no support to maintain them. Unfortunately, the abuse of antibiotics in inpatient and outpatient NBs is foolish. Its negative impact on neonatal health and the economy is a public health problem of epidemiological and even epidemic proportions. This manuscript is a shortened version of the 10th Clinical Consensus of the Ibero-American Society of Neonatology (SIBEN) on suspected neonatal sepsis at the end of 2018, updated with publications from its completion to February 2020. This manuscript describes useful strategies for everyday neonatal practice when neonatal sepsis is suspected, along with important aspects about the indisputable value of clinical evaluation of the NB and about obtaining and interpreting blood cultures, urine cultures, and other cultures. Likewise, the low value of laboratory tests in suspected neonatal sepsis is demonstrated with evidence and clinical recommendations are made on the appropriate use of antibiotics.

Abstract
Urinary tract infection (UTI) is defined as the growth of a significant number of microorganisms of a single species in the urine, in the presence of symptoms. Symptoms in young children are non-specific such as fever without focus; young infants may manifest with irritability, failure to thrive, jaundice, vomiting and diarrhea. Older children usually have symptoms of cystitis or pyelonephritis. Symptoms of cystitis are dysuria, frequency, new onset incontinence and malodorous urine while symptoms of pyelonephritis are high grade fever, flank pain and vomiting. Rapid urine testing by microscopy for pus cells, dipstick testing for leukocyte esterase and nitrite, and enhanced urinalysis are supportive tests. Urine culture samples should be collected with proper technique and results interpreted for significant growth accordingly. Antibiotic therapy for 7-14 d for complicated UTI and 3-4 d for uncomplicated UTI is adequate. Further evaluation is recommended clinically for bladder-bowel dysfunction and obvious anatomical defects and by imaging for vesicoureteral reflux (VUR), usually by micturating cystourethrography (MCU). Since MCU involves exposure to radiation and urethral catheterization, it is now reserved for children with parenchymal involvement or recurrent UTI. VUR is the backward flow of urine into one or both ureters. Clinical manifestations other than UTI include incidental diagnosis on antenatal ultrasonography. Reflux nephropathy, the renal scarring associated with VUR may manifest clinically as hypertension, proteinuria and renal failure. The management of VUR is primarily with antibiotic prophylaxis. Anatomical correction is indicated in case of breakthrough febrile UTI. No intervention has been shown to reduce renal scarring.

Abstract
BACKGROUND A link between vitamin D deficiency and susceptibility to bacterial and viral infections has recently been suggested. AIM To investigate a possible association between vitamin D deficiency and urinary tract infection (UTI). METHODS A case-control study was undertaken comprising 75 children aged 2-7 years with UTI (cases) compared with 75 healthy controls in terms of serum 25 hydroxyvitamin D [25(OH)D] levels. Serum 25(OH)D levels were measured using a chemiluminescence assay. For cases, dimercaptosuccinic acid (DMSA) renal scan was used as the gold standard to distinguish between acute lower UTI (cystitis) and acute pyelonephritis. RESULTS Median (IQR) 25(OH)D levels were lower in the UTI group [14.5 ng/mL (9.4-18.8)] than in the controls [27 ng/mL (22.4-39.0)] (p< 0.001). In addition, the prevalence of 25(OH)D levels <20 ng/mL was higher in the children with UTI than in the controls (68% vs 18%) (p< 0.001). There was a statistically significant difference between the cystitis and pyelonephritis groups in mean (SD) serum 25(OH)D levels-18.76 (9.35) ng/mL vs 13.94 (6.97) ng/mL, p< 0.05, respectively. CONCLUSION Low serum vitamin D is associated with UTI and supports the hypothesis that children with low vitamin D levels could be at greater risk of UTI.

Abstract
AIM To explore Italian paediatric nurses' reported burnout and its relationship to their perceptions of safety and adverse events. DESIGN A cross-sectional study using the RN4CAST@IT-Ped database with a web-based survey design. METHODS The RN4CAST@IT-Ped questionnaire was used to collect data in 2017. This comprised three main components: three dimensions (22 items) of the Maslach Burnout Inventory including emotional exhaustion, depersonalization and personal accomplishment. Participants also scored an overall grade of patient safety and estimated the occurrence of adverse clinical events. RESULTS Nurses (N = 2,243) reported high levels of burnout. Most rated clinical safety as high. The risk of adverse events ranged from 1.3-12.4%. The degree of burnout appeared to influence the perception of safety and adverse events. CONCLUSION The association between nurses' burnout and perceptions of higher rates of adverse events and reduced safety in clinical practice is an important finding. However, it is unclear whether this was influenced by a negative state of mind, and whether reduced safety and increased adverse events negatively influenced nurses' well-being, thus leading to burnout. Regardless, the association between nurses' burnout and these quality concepts needs further exploration to examine the effect, if any, on burnout and safety, and identify supportive mechanisms for nurses. IMPACT The association between reported burnout and perception of safety and risk of adverse events in Italian paediatric nurses has been reported for the first time. Nurses reporting burnout are at greater risk of intensely negative perceptions of clinical safety and adverse events. This is an important finding as perceptions can influence practice and behaviours. Quality measures in children's clinical environments need to go beyond obvious indicators to examine nurses' well-being as this also influences quality and safety.

Abstract
OBJECTIVES To determine if a multicomponent intervention was associated with increased use of first-line antibiotics (cephalexin or sulfamethoxazole and trimethoprim) among children with uncomplicated urinary tract infections (UTIs) in outpatient settings. METHODS The study was conducted at Kaiser Permanente Colorado, a large health care organization with ∼127 000 members <18 years of age. After conducting a gap analysis, an intervention was developed to target key drivers of antibiotic prescribing for pediatric UTIs. Intervention activities included development of new local clinical guidelines, a live case-based educational session, pre- and postsession e-mailed knowledge assessments, and a new UTI-specific order set within the electronic health record. Most activities were implemented on April 26, 2017. The study design was an interrupted time series comparing antibiotic prescribing for UTIs before versus after the implementation date. Infants <60 days old and children with complex urologic or neurologic conditions were excluded. RESULTS During January 2014 to September 2018, 2142 incident outpatient UTIs were identified (1636 preintervention and 506 postintervention). Pyelonephritis was diagnosed for 7.6% of cases. Adjusted for clustering of UTIs within clinicians, the proportion of UTIs treated with first-line antibiotics increased from 43.4% preintervention to 62.4% postintervention (P < .0001). The use of cephalexin (first-line, narrow spectrum) increased from 28.9% preintervention to 53.0% postintervention (P < .0001). The use of cefixime (second-line, broad spectrum) decreased from 17.3% preintervention to 2.6% postintervention (P < .0001). Changes in prescribing practices persisted through the end of the study period. CONCLUSIONS A multicomponent intervention with educational and process-improvement elements was associated with a sustained change in antibiotic prescribing for uncomplicated pediatric UTIs.

Abstract
BACKGROUND The 2011 American Academy of Pediatrics clinical practice guideline recommends when to obtain renal and bladder ultrasound (RBUS) and voiding cystourethrography (VCUG) following febrile urinary tract infection (UTI) for children age 2-24 months. However, there is not consensus about when to obtain imaging in neonates. The objective of this study is to evaluate UTI diagnostic criteria along with RBUS and VCUG in neonates admitted to the NICU in the first 3 months of life. METHODS A retrospective electronic medical record review was performed of neonates admitted to Nationwide Children's Hospital system NICUs between January 2010 and December 2014 with UTI as a primary or secondary diagnosis. Urine culture results were evaluated versus established UTI criteria and renal US and VCUG results were compared. RESULTS Of 81 patients with a straight catheterized urine culture obtained, 28 patients met laboratory criteria for diagnosis of UTI and all but 4 had a RBUS. Urine cultures had an equal distribution of Enterobacter cloacae, Escherichia coli, Klebsiella pneumoniae, and Coagulase negative staphylococcus. RBUS showed dilation of the collecting system in 37.5% of patients with UTI compared to 41.3% without UTI. VCUG showed vesicourteral reflux (VUR) on 41.7% of those with UTI compared to 34.8% without UTI. For patients with UTI, the sensitivity of RBUS for VUR on VCUG was 60% with CI [0.17, 0.93] and specificity was 43% with CI [0.12, 0.80]. In patients without UTI, sensitivity of RBUS for VUR on VCUG was 63% with CI [0.26, 0.90] and specificity was 71% with CI [0.42, 0.90]. CONCLUSIONS Fewer than half of neonates that were diagnosed clinically with UTI met laboratory criteria for a UTI. Positive urine cultures grew a wide variety of organisms. The sensitivity of renal ultrasound for VUR is only about 60%.

Abstract
BACKGROUND Urinary tract infection (UTI) is common in children. The purpose of this retrospective study was to determine the various risk factors that usually affect the prognosis of UTI in children diagnosed with the disease. METHODS In the present retrospective study, we enrolled all pediatric patients diagnosed with UTI and hospitalized between 1 January 2013 and 31 July 2016 at Nanjing Children's Hospital. We then collected all the relevant patient clinical demographics and characteristics. RESULTS The study involved 2,092 pediatric patients diagnosed with UTI. On logistic regression analysis, factors that could affect the prognosis of pediatric UTI were complications, hospitalization, intensive care unit (ICU) admission, type of UTI, urine culture results, blood lymphocytes, urine nitrites (NIT) and antibiotics (unstandardized coefficients, 0.06, <0.001, -0.28, 0.32, <0.001, 0.01, -0.11, 0.01, respectively, all P < 0.001). CONCLUSION Complications, hospitalization, type of UTI, urine culture results, blood lymphocytes, and antibiotics had a significant, positive association with UTI prognosis. Meanwhile, ICU admission and urine NIT had a negative association with prognosis.

Abstract
BACKGROUND Urinary Tract Infection (UTI) is a common infection in children. Prompt diagnosis and appropriate treatment are very important to reduce the morbidity associated with this condition. OBJECTIVE To provide an update on the evaluation, diagnosis, and treatment of urinary tract infection in children. METHODS A PubMed search was completed in clinical queries using the key terms "urinary tract infection", "pyelonephritis" OR "cystitis". The search strategy included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews. The search was restricted to English literature and the pediatric age group. Patents were searched using the key terms "urinary tract infection" "pyelonephritis" OR "cystitis" from www.google.com/patents, http://espacenet.com, and www.freepatentsonline.com. RESULTS Escherichia coli accounts for 80 to 90% of UTI in children. The symptoms and signs are nonspecific throughout infancy. Unexplained fever is the most common symptom of UTI during the first two years of life. After the second year of life, symptoms and signs of pyelonephritis include fever, chills, rigor, flank pain, and costovertebral angle tenderness. Lower tract symptoms and signs include suprapubic pain, dysuria, urinary frequency, urgency, cloudy urine, malodorous urine, and suprapubic tenderness. A urinalysis and urine culture should be performed when UTI is suspected. In the work-up of children with UTI, physicians must judiciously utilize imaging studies to minimize exposure of children to radiation. While waiting for the culture results, prompt antibiotic therapy is indicated for symptomatic UTI based on clinical findings and positive urinalysis to eradicate the infection and improve clinical outcome. The choice of antibiotics should take into consideration local data on antibiotic resistance patterns. Recent patents related to the management of UTI are discussed. CONCLUSION Currently, a second or third generation cephalosporin and amoxicillin-clavulanate are drugs of choice in the treatment of acute uncomplicated UTI. Parenteral antibiotic therapy is recommended for infants ≤ 2 months and any child who is toxic-looking, hemodynamically unstable, immunocompromised, unable to tolerate oral medication, or not responding to oral medication. A combination of intravenous ampicillin and intravenous/intramuscular gentamycin or a third-generation cephalosporin can be used in those situations. Routine antimicrobial prophylaxis is rarely justified, but continuous antimicrobial prophylaxis should be considered for children with frequent febrile UTI.

Acquisition, Divergence, and Personalization of the Female Perineal Microbiomes Are Driven by Developmental Milestones and Disrupted by Urinary Tract Infection: A Pilot Study. Front Pediatr 2020; 8:542413. [PMID: 33364220 PMCID: PMC7752998 DOI: 10.3389/fped.2020.542413] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2020] [Accepted: 11/04/2020] [Indexed: 12/11/2022] Open
Abstract
Introduction: The pediatric perineal microbiomes inhabit a dynamic environment with changes related to diet, toileting habits, and hormonal development. We hypothesized that next-generation sequencing would reveal different perineal bacterial signatures associated with developmental milestones in premenstrual females. Furthermore, we predicted that these microbial changes would be disrupted in premenstrual females with a history of urinary tract infection (UTI). Study Design: Healthy females were recruited at well-child visits. Subjects were divided into 4 developmental groups: (1) 0-3 month old newborns; (2) 4-10 month old infants transitioning to solid foods; (3) 2-6 year old toddlers peri-toilet training; and (4) 7-12 year old premenstrual girls. A separate group of females with a history of culture proven UTI and off antibiotics >1 month was also recruited. DNA was isolated from swabs of the perineum and subjected to 16S rRNA sequencing. The diversity and species changes between developmental cohorts and age matched children with history of UTI was determined. Results: A total of 75 subjects were recruited: 15 in each group. There was a clear evolution of the perineal microbiomes with development. There was a significant microbial disruption in girls with a history of UTI, irrespective of developmental milestone age group. The periurethral/perivaginal site displayed greater changes in microbiome structure than other sites in girls with a history of UTI. Discussion: This pilot study evaluates the normal microbiome of the premenstrual girl at specific developmental milestones. Although the number of children per cohort was limited to 15, we observed statistical significance corresponding with developmental milestones. This study provides the first, culture independent delineation of the development of the perineal microbiome in girls. Furthermore, the sites closest to the site of infection appear to be more sensitive to antibiotic remodeling than those more distant. The factors that remodel the perineal microbiomes and predispose females, particularly girls, to UTIs (e.g., increase in uropathogen presence, absence of protective organisms) are unclear. Identification of specific signatures that increase susceptibility to UTI and their sequelae will improve patient care and promote personalized medicine.

Abstract
The lower urinary tract is routinely exposed to microbes residing in the gastrointestinal tract, yet the urothelium resists invasive infections by gut microorganisms. This infection resistance is attributed to innate defenses in the bladder urothelium, kidney epithelium, and resident or circulating immune cells. In recent years, surmounting evidence suggests that these cell types produce and secrete soluble host defense peptides, including members of the Ribonuclease (RNase) A Superfamily, to combat invasive bacterial challenge. While some of these peptides, including RNase 4 and RNase 7, are abundantly produced by epithelial cells, the expression of others, like RNase 3 and RNase 6, increase at infection sites with immune cell recruitment. The objective of this mini-review is to highlight recent evidence showing the biological importance and responses of RNase A Superfamily members to infection in the kidney and bladder.

Abstract
BACKGROUND Extended-spectrum-beta-lactamase (ESBL)-producing bacteria are an increasingly important cause of urinary tract infections (UTIs) worldwide. We evaluated clinical characteristics and associated risk factors of UTIs in young children according to ESBL-producing status and relapse rates. METHODS All urinary culture results in patients younger than 2 years old were assessed, and only children with febrile UTIs from gram-negative bacterial infections were reviewed. RESULTS Of 845 episodes evaluated, 146 (17.3%) were caused by ESBL-positive bacteria. Significant differences were observed in previous UTIs, use of antibiotics or history of hospitalization within previous 3 months, and underlying urinary abnormalities between the ESBL UTI and non-ESBL UTI groups. After 2 weeks of treatment completion, UTI relapse occurred in 2.7% of children in the ESBL group and 1.1% of children in the non-ESBL group (P = 0.13). In the ESBL UTI group, relapse rate was not significantly different between patients treated with susceptible antibiotics and those treated with non-susceptible but clinically effective antibiotics. CONCLUSIONS Previous history of UTI, antibiotic treatment, or hospitalization within previous 3 months and underlying disease are risk factors for ESBL UTI in children under 24 months of age. However, relapse rate was < 3% regardless of in vitro susceptibility of the treating antibiotics, as long as the antibiotics were clinically effective. We cautiously propose that we may continue the use of initial empirical antibiotics when a definite clinical response is observed, although further study is necessary to confirm the findings of this study.

Abstract
PURPOSE Urinary tract infections (UTIs) are common bacterial infections among children. OBJECTIVE To systematically review the antimicrobials used for febrile UTIs in paediatric clinical trials and meta-analyse the observed cure rates and reasons for treatment failure. MATERIALS AND METHODS We searched Medline, Embase and Cochrane central databases between January 1, 1990, and November 24, 2016, combining MeSH and free-text terms for: "urinary tract infections", AND "therapeutics", AND "clinical trials" in children (age range 0-18 years). Two independent reviewers assessed study quality and performed data extraction. The major outcome measures were clinical and microbiological cure rates according to different antibiotics. RESULTS We identified 2762 published studies and included 30 clinical trials investigating 3913 cases of paediatric febrile urinary tract infections. Children with no underlying condition were the main population included in the trials (n = 2602; 66.5%). Cephalosporins were the most frequent antibiotics studied in trials (22/30, 73.3%). Only a few antibiotics active against resistant UTIs have been tested in randomised clinical trials, mainly aminoglycosides. The average point cure rate of all investigational drugs was estimated to 95.3% (95% CI 93.5-96.9%). Among 3002 patients for whom cure and failure rates were reported, only 3.9% (3.9%; 118/3002) were considered clinically to have treatment failure, while 135 (4.5%; 135/3002) had microbiological failure. CONCLUSIONS We observed high treatment cure rates, regardless of the investigational drug chosen, the route of administration, duration and dosing. This suggests that future research should prioritise observational studies and clinical trials on children with multi-drug-resistant infections.

Abstract
Purpose of review This review highlights the most common congenital anomalies of the kidney and urinary tract (CAKUT) that are encountered in pediatric practices. CAKUT are the most common cause of prenatally diagnosed developmental malformations and encompass a spectrum of disorders impacting lower urinary tract development as well as kidney development and function. In pediatric and adolescent populations, developmental abnormalities are the leading cause of end-stage kidney disease. The goal of this review is to provide pediatric providers a framework for appropriate clinical management as well as highlight when referral to subspecialty care is needed. Recent findings While the exact etiologies of CAKUT are not completely defined, new evidence demonstrates that genetic and molecular changes impact embryonic kidney and urinary tract development. As a result, phenotypes and clinical outcomes may be affected. Summary Because pediatric providers provide front-line care to children and adolescents with developmental kidney and urinary tract anomalies, updated knowledge of CAKUT pathogenesis, embryology, clinical management, and patient outcomes is needed. This manuscript reviews CAKUT etiologies and essential diagnostic, prognostic, and management strategies.
