Sari C, Demirbağ BC. Investigation of anxiety levels in caregivers who perform clean intermittent catheterization on their children and affecting factors. Neurourol Urodyn 2024; 43:738-747. [PMID: 38238988 DOI: 10.1002/nau.25388] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2023] [Revised: 11/20/2023] [Accepted: 12/21/2023] [Indexed: 03/21/2024]
Abstract
PURPOSE The study aimed to determine the anxiety levels of caregivers who performed clean intermittent catheterization (CIC) on their children and the factors affecting them. METHODS This descriptive study was conducted between January 6, and May 29, 2023 with caregivers of 42 patients who were followed up by the pediatric nephrology outpatient clinic of a university for CIC. The study data were collected using the "Participant Information Form" and the "State and Trait Anxiety Scale." RESULTS According to the results, of the children included in the study, 73.8% were female, 64.3% were diagnosed with spina bifida (SB), and 76.2% received CIC applications 4-6 times a day. All the caregivers were mothers, and 76.2% received CIC training from a doctor. However, 78.6% of them found the training insufficient, leading them to rely on self-experimentation when applying CIC to their own children. None of the caregivers received information or training on the CIC application from nurses, and there were no home visits or telephone counseling provided after the hospital discharge. The mean score for the state anxiety scale among the caregivers was 45.90 ± 10.57, while the mean score for the trait anxiety scale was 46.92 ± 8.43. Significantly higher mean trait anxiety scores were observed among caregivers with chronic diseases who did not receive training on the CIC application (p < 0.05). Additionally, caregivers of children who experienced 3-4 urinary tract infections (UTIs) within the last 3 months also had significantly higher mean trait anxiety scores (p < 0.05). The mean trait anxiety level scores of caregivers of children who had 3-4 UTIs in the last 3 months were significantly higher (p < 0.05). CONCLUSIONS It was concluded that caregivers' lack of training on CIC implementation, having chronic disease, and having frequent UTIs in their children were effective on anxiety levels.

Abstract
Background: Urinary tract infection (UTI) represents one of the most common infectious diseases and a major cause of antibiotic prescription in children. To prevent recurrent infections and long-term complications, low-dose continuous antibiotic prophylaxis (CAP) has been used. However, the efficacy of CAP is controversial. The aim of this document was to develop updated guidelines on the efficacy and safety of CAP to prevent pediatric UTIs. Methods: A panel of experts on pediatric infectious diseases, pediatric nephrology, pediatric urology, and primary care was asked clinical questions concerning the role of CAP in preventing UTIs in children. Overall, 15 clinical questions were addressed, and the search strategy included accessing electronic databases and a manual search of gray literature published in the last 25 years. After data extraction and narrative synthesis of results, recommendations were developed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) methodology. Results: The use of CAP is not recommended in children with a previous UTI, with recurrent UTIs, with vesicoureteral reflux (VUR) of any grade, with isolated hydronephrosis, and with neurogenic bladder. CAP is suggested in children with significant obstructive uropathies until surgical correction. Close surveillance based on early diagnosis of UTI episodes and prompt antibiotic therapy is proposed for conditions in which CAP is not recommended. Conclusions: Our systematic review shows that CAP plays a limited role in preventing recurrences of UTI in children and has no effect on its complications. On the other hand, the emergence of new antimicrobial resistances is a proven risk.

Jiang M, Deng J, Zhou G, Li S, Liu G. Risk factors for recurrent urinary tract infection in children with neurogenic bladder following clean intermittent catheterization. Urology 2022; 164:224-229. [PMID: 35026189 DOI: 10.1016/j.urology.2021.12.027] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2021] [Revised: 12/23/2021] [Accepted: 12/28/2021] [Indexed: 10/19/2022]
Abstract
OBJECTIVE To investigate the risk factors for recurrent urinary tract infection (UTI) in children with a neurogenic bladder (NB) managed by clean intermittent catheterization (CIC). METHODS Over a 5-year period, we retrospectively assessed the risk factors for recurrent UTIs in children (age 9-151 months) who had CIC. All patients were followed up for more than 12 months and had at least two clinic visits during the study period. Demographic, clinical, and urodynamic parameters were assessed. All data were compared between the recurrent UTI (>1.0 UTI/study-year) and episodic UTI (≤1.0 UTI/study-year) groups. RESULTS Of 327 patients, 79 (24.2%) had recurrent UTIs and 248 (75.8%) had episodic UTIs. Univariate and multivariate analyses showed that older age, lumbar level lesions, long duration of NB, presence of vesicoureteral reflux (VUR), increased bladder wall thickness (BWT), and low bladder compliance were the significant factors for recurrent UTIs. Bladder trabeculation was associated with recurrent UTIs on univariate analysis, but not on multivariate analysis. During the follow-up period, chronic renal insufficiency was diagnosed in 31 (39.2%) and 29 patients (11.7%) in the recurrent and episodic UTI groups (p<0.05), respectively. CONCLUSIONS These results suggest that older age, high level of spinal cord lesions, long duration of NB, VUR, increased BWT, and low bladder compliance may be directly associated with recurrent UTIs in children with NB. Children with NB might have higher susceptibility to chronic renal insufficiency after recurrent UTIs.

The impact of constant antibiotic prophylaxis in children affected by spinal dysraphism performing clean intermittent catheterization: a 2-year monocentric retrospective analysis. Childs Nerv Syst 2022; 38:605-610. [PMID: 34523011 PMCID: PMC8917099 DOI: 10.1007/s00381-021-05337-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Accepted: 08/14/2021] [Indexed: 11/05/2022]
Abstract
INTRODUCTION Spinal dysraphism (SD) is a general term used to refer to developmental abnormalities of the spine that involves many clinical conditions including myelomeningocele (MMC). In these patients, neurogenic bladder (NB) is a common and predisposing factor for renal damage; the most frequently used approach to manage this situation is based on clean intermittent catheterization (CIC) and anticholinergic drugs. Urinary tract infections (UTIs) are a significant concern for these patients, and antibiotic prophylaxis is frequently used even if it is still a debated topic of literature. The purpose of this paper is to investigate the role and the real effectiveness of antibiotic prophylaxis in the reduction of incidence of UTIs in patients with spina bifida performing CIC. METHODS We collected data of all patients performing CIC, who did their last follow-up visit in the period between January 2019 and January 2021, followed at the children multidisciplinary Spina Bifida Center of A. Gemelli Hospital in Rome. Data collected included age at referral, gender, type of SD lesion, serum creatinine and cystatin C levels, the use of anticholinergic medications, antibiotic prophylaxis and type of prophylaxis (oral/endovesical), age of starting prophylaxis with its duration/adherence, number of CIC/day and its duration, episodes of UTIs in the 2 years prior to the last follow-up, and presence and grade of vesical-ureteric reflux (VUR) on cystourethrogram. RESULTS A total of 121 patients with SD performing CIC was included in the study; 66 (54%) presented ≥ 1 episode of UTIs in the last two years and 55 (46%) none. During the study period, 85 (70%) patients received antibiotic prophylaxis (ABP group) and 36 (30%) did not (NABP group): no statistically significative difference in terms of UTI development was observed between the two groups (p = 0.17). We also evaluated compliance to the therapy; 71 patients (59%) took antibiotic prophylaxis constantly (CABP group) and 50 (41%) did not do antibiotic prophylaxis constantly or did not do antibiotic prophylaxis at all (NCABP group): we observed a statistically significative difference in terms of UTIs with a 2.2 times higher risk of development at least one episode of UTIs in NCABP group. CONCLUSION In conclusion, antibiotic prophylaxis performed constantly, without interruption, is associated with a lower risk of developing urinary tract infections and consequently to develop renal failure in adulthood.

Abstract
AbstractObjective:Ambulatory healthcare-associated infections (HAIs) occur frequently in children and are associated with morbidity. Less is known about ambulatory HAI costs. This study estimated additional costs associated with pediatric ambulatory central-line–associated bloodstream infections (CLABSIs), catheter-associated urinary tract infections (CAUTI), and surgical site infections (SSIs) following ambulatory surgery.Design:Retrospective case-control study.Setting:Four academic medical centers.Patients:Children aged 0–22 years seen between 2010 and 2015 and at risk for HAI as identified by electronic queries.Methods:Chart review adjudicated HAIs. Charges were obtained for patients with HAIs and matched controls 30 days before HAI, on the day of, and 30 days after HAI. Charges were converted to costs and 2015 USD. Mixed-effects linear regression was used to estimate the difference-in-differences of HAI case versus control costs in 2 models: unrecorded charge values considered missing and a sensitivity analysis with unrecorded charge considered $0.Results:Our search identified 177 patients with ambulatory CLABSIs, 53 with ambulatory CAUTIs, and 26 with SSIs following ambulatory surgery who were matched with 382, 110, and 75 controls, respectively. Additional cost associated with an ambulatory CLABSI was $5,684 (95% confidence interval [CI], $1,005–$10,362) and $6,502 (95% CI, $2,261–$10,744) in the 2 models; cost associated with a CAUTI was $6,660 (95% CI, $1,055, $12,145) and $2,661 (95% CI, −$431 to $5,753); cost associated with an SSI following ambulatory surgery at 1 institution only was $6,370 (95% CI, $4,022–$8,719).Conclusions:Ambulatory HAI in pediatric patients are associated with significant additional costs. Further work is needed to reduce ambulatory HAIs.

[PMID: 32197933 DOI: 10.1016/j.jpurol.2020.02.009] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2019] [Accepted: 02/16/2020] [Indexed: 01/24/2023]
Abstract
INTRODUCTION Damage to the glycosaminoglycan layer of the urothelium, which is composed of hyaluronic acid (HA), may increase the possibility of bacterial adherence and infections. Patients with neurogenic bladder (NB) who perform clean intermittent catheterization (CIC) 4-6 times a day are also under great risk for recurrent urinary tract infections (RUTIs). OBJECTIVE The aim of this study was to assess the efficacy and safety of intravesical HA in reducing the frequency of RUTIs in patients with spina bifida (SB) and NB, who perform CIC. MATERIALS AND METHODS Ten patients (nine girls, one boy) with SB and NB affected by RUTIs received intravesical instillation of HA. Ten patients (seven girls, three boys) with SB and NB who did not accept the intravesical HA therapy were included in the control group. All patients developed symptomatic RUTIs, which occurred at least three times in the previous 12 months. The study group was treated with intravesical 40 mg HA (Hyacyst®) weekly for four weeks, then monthly for the consequent three months. Recurrence of UTIs before and after the treatment was analyzed. RESULTS The mean age of the study group and the controls were 11.1 ± 4.8 (3.2-18.6) and 9.3 ± 5.4 (2.1-16.2) years, respectively. The mean UTIs per patient-month in the study group and the controls were 0.34 ± 0.05 and 0.35 ± 0.06, respectively. The mean follow-up time after the treatment was 16.6 ± 6.9 months in the study group and 16 ± 6.1 months in the controls. The mean UTIs per patient-month significantly decreased in the study group after the treatment (p < 0.001) but showed no significant difference in the control group (p = 0.174). When study and control groups were compared, the mean UTIs per patient-month showed no significant difference before treatment (p = 0.77) but significantly decreased in the study group after the treatment (p < 0.001). DISCUSSION To the best of the authors' knowledge, this study is the first one evaluating the efficacy of intravesical HA in the treatment of RUTIs in children with SB and NB. However, this study has several limitations, such as the small sample size and short follow-up time. CONCLUSION The findings of the present study indicate that intravesical HA is an effective and safe treatment that reduces RUTIs in patients with SB and NB, who perform CIC.

Abstract
INTRODUCTION Our objective was to provide guidelines covering all aspects of intermittent catheterisation (intermittent self-catheterisation and third-party intermittent catheterisation). MATERIALS AND METHODS A systematic review of the literature based on Pubmed, Embase, Google scholar was initiated in December 2014 and updated in April 2019. Given the lack of robust data and the numerous unresolved controversial issues, guidelines were established based on the formal consensus of experts from steering, scoring and review panels. RESULTS This allowed the formulation of 78 guidelines, extending from guidelines on indications for intermittent catheterisation, modalities for training and implementation, choice of equipment, management of bacteriuria and urinary tract infections, to the implementation of intermittent catheterisation in paediatric, geriatric populations, benign prostatic hyperplasia patients and continent urinary diversion patients with a cutaneous reservoir as well as other complications. These guidelines are pertinent to both intermittent self-catheterisation and third-party intermittent catheterisation. CONCLUSION These are the first comprehensive guidelines specifically aimed at intermittent catheterisation and extend to all aspects of intermittent catheterisation. They assist in the clinical decision-making process, specifically in relation to indications and modalities of intermittent catheterisation options. These guidelines are intended for urologists, gynaecologists, geriatricians, paediatricians, neurologists, physical and rehabilitation physicians, general practitioners and other health professionals including nurses, carers….

Outcome of Different Approaches to Reduce Urinary Tract Infection in Patients With Spinal Cord Lesions: A Systematic Review. Am J Phys Med Rehabil 2020; 99:1056-1066.

Abstract
Neurogenic bladder disorders are common among patients with spinal cord lesions, which often result in upper and lower urinary tract complications. Urinary tract infection has remained the most frequent type of infection in this population. Our aim is to review systematically the literature on the outcome of different intervention methods to reduce urinary tract infection incidence. A literature search was conducted in the database of Medline, PubMed, Embase, and Scopus. After screening 1559 articles, 42 were included in this review. The intervention methods can be categorized into the four following groups: (1) indwelling catheterization and intermittent catheterization, (2) medications, (3) surgery, and (4) others. Intermittent catheterization is still the most recommended treatment for persons with spinal cord lesions. Hydrophilic catheters are more suitable for adults than children because of complex handling. Bladder management with spontaneous voiding is initially considered for infants and toddlers with spina bifida. Antibiotics treatment should be based on the results of urine cultures. Shortening the course of antibiotics treatment can reduce its adverse effects but may increase urinary tract infection recurrence. Because botulinum toxin injections and bladder surgery can improve urodynamic function, both are conducive toward lowering urinary tract infection incidence.

Abstract
BACKGROUND People carrying out clean intermittent self-catheterisation (CISC) to empty their bladder often suffer repeated urinary tract infections (UTIs). Continuous once-daily, low-dose antibiotic treatment (antibiotic prophylaxis) is commonly advised but knowledge of its effectiveness is lacking. OBJECTIVE To assess the benefit, harms and cost-effectiveness of antibiotic prophylaxis to prevent UTIs in people who perform CISC. DESIGN Parallel-group, open-label, patient-randomised 12-month trial of allocated intervention with 3-monthly follow-up. Outcome assessors were blind to allocation. SETTING UK NHS, with recruitment of patients from 51 sites. PARTICIPANTS Four hundred and four adults performing CISC and predicted to continue for ≥ 12 months who had suffered at least two UTIs in the previous year or had been hospitalised for a UTI in the previous year. INTERVENTIONS A central randomisation system using random block allocation set by an independent statistician allocated participants to the experimental group [once-daily oral antibiotic prophylaxis using either 50 mg of nitrofurantoin, 100 mg of trimethoprim (Kent Pharmaceuticals, Ashford, UK) or 250 mg of cefalexin (Sandoz Ltd, Holzkirchen, Germany); n = 203] or the control group of no prophylaxis (n = 201), both for 12 months. MAIN OUTCOME MEASURES The primary clinical outcome was relative frequency of symptomatic, antibiotic-treated UTI. Cost-effectiveness was assessed by cost per UTI avoided. The secondary measures were microbiologically proven UTI, antimicrobial resistance, health status and participants' attitudes to antibiotic use. RESULTS The frequency of symptomatic antibiotic-treated UTI was reduced by 48% using prophylaxis [incidence rate ratio (IRR) 0.52, 95% confidence interval (CI) 0.44 to 0.61; n = 361]. Reduction in microbiologically proven UTI was similar (IRR 0.49, 95% CI 0.39 to 0.60; n = 361). Absolute reduction in UTI episodes over 12 months was from a median (interquartile range) of 2 (1-4) in the no-prophylaxis group (n = 180) to 1 (0-2) in the prophylaxis group (n = 181). The results were unchanged by adjustment for days at risk of UTI and the presence of factors giving higher risk of UTI. Development of antimicrobial resistance was seen more frequently in pathogens isolated from urine and Escherichia coli from perianal swabs in participants allocated to antibiotic prophylaxis. The use of prophylaxis incurred an extra cost of £99 to prevent one UTI (not including costs related to increased antimicrobial resistance). The emotional and practical burden of CISC and UTI influenced well-being, but health status measured over 12 months was similar between groups and did not deteriorate significantly during UTI. Participants were generally unconcerned about using antibiotics, including the possible development of antimicrobial resistance. LIMITATIONS Lack of blinding may have led participants in each group to use different thresholds to trigger reporting and treatment-seeking for UTI. CONCLUSIONS The results of this large randomised trial, conducted in accordance with best practice, demonstrate clear benefit for antibiotic prophylaxis in terms of reducing the frequency of UTI for people carrying out CISC. Antibiotic prophylaxis use appears safe for individuals over 12 months, but the emergence of resistant urinary pathogens may prejudice longer-term management of recurrent UTI and is a public health concern. Future work includes longer-term studies of antimicrobial resistance and studies of non-antibiotic preventative strategies.

Abstract
BACKGROUND Urinary tract infection (UTI) is common in children. Symptoms include fever, lethargy, anorexia, and vomiting. UTI is caused by Escherichia coli in over 80% of cases and treatment is a course of antibiotics. Due to acute illness caused by UTI and the risk of pyelonephritis-induced permanent kidney damage, many children are given long-term (several months to 2 years) antibiotics aimed at preventing recurrence. This is the third update of a review first published in 2001 and updated in 2006, and 2011. OBJECTIVES To assess whether long-term antibiotic prophylaxis was more effective than placebo/no treatment in preventing recurrence of UTI in children, and if so which antibiotic in clinical use was the most effective. We also assessed the harms of long-term antibiotic treatment. SEARCH METHODS We searched the Cochrane Kidney and Transplant Register of Studies up to 30 July 2018 through contact with the Cochrane Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal, and ClinicalTrials.gov. SELECTION CRITERIA Randomised comparisons of antibiotics with other antibiotics, placebo or no treatment to prevent recurrent UTI in children. DATA COLLECTION AND ANALYSIS Two authors independently assessed and extracted information for the initial and previous updates. A random-effects model was used to estimate risk ratio (RR) and risk difference (RD) for recurrent UTI with 95% confidence intervals (CI). MAIN RESULTS In this update sixteen studies (2036 children randomised, 1977 analysed) were included. Seven studies (612 children) compared two or more types of antibiotics, six (1088 children) compared antibiotics with placebo or no treatment, one four-armed study compared circumcision with and without antibiotic treatment, one study compared dose of antibiotic, and one three-armed study compared two different antibiotics as well as no treatment. Of the sixteen included studies only one study was judged to be at low risk of bias for all domains, with the majority judged to be at unclear risk of bias due to very poorly reported methodology. The number of studies judged to be a low risk of bias was: selection bias (7); performance bias (4); detection bias (1); attrition bias (6); reporting bias (7); and other bias (2). The number of studies judged to be at high risk of bias was: selection bias (0); performance bias (5); detection bias (1); attrition bias (4); reporting bias (6); and other bias (1).Compared to placebo/no treatment, antibiotics lead to a modest decrease in the number of repeat symptomatic UTI in children; however the estimate from combining all studies was not certain and the confidence interval indicates low precision indicating that antibiotics may make little or no difference to risk of repeat infection (RR 0.75, 95% CI 0.28 to 1.98). When we combined only the data from studies with concealed treatment allocation, there was a similar reduction in risk of repeat symptomatic UTI in children taking antibiotics (RR 0.68) and we have greater certainty in this estimate because of the more robust study designs, the confidence interval is smaller and it does not include the point of no effect (95% CI 0.48 to 0.95). The estimated reduction in risk of repeat symptomatic UTI for children taking antibiotics was similar in children with vesicoureteric reflux (VUR) (RR 0.65, 95% CI 0.39 to 1.07) compared to those without VUR (RR 0.56, 95% CI 0.15 to 2.12) however there was considerable uncertainty due to imprecision from fewer events in the smaller group of children with VUR. There was no consistency in occurrence of adverse events, with one study having more events in the placebo group and a second study having more events in the antibiotics group. Three studies reported data for antibiotic resistance with the analysis estimating the risk of a UTI caused by a bacteria resistant to the prophylactic antibiotic being almost 2.5 times greater in children on antibiotics than for children on placebo or no treatment (RR 2.40, 95% CI 0.62 to 9.26). However the confidence interval is wide, showing imprecision and there may be little or no difference between the two groups.Eight studies involving 659 children compared one antibiotic with another but few studies compared the same combination for the same outcome so little data could be pooled. Two studies reported microbial resistance data and analysis showed that treatment with nitrofurantoin may lead to a lower risk of a UTI caused by a bacteria resistant to the treatment drug compared to children given trimethoprim-sulphamethoxazole as their prophylactic treatment (RR 0.54, 95% CI 0.31 to 0.92). AUTHORS' CONCLUSIONS Long-term antibiotics may reduce the risk of repeat symptomatic UTI in children who have had one or more previous UTIs but the benefit may be small and must be considered together with the increased risk of microbial resistance.

Abstract
BACKGROUND Urinary tract infection is more common in children with spina bifida (SB) than neurologically intact children, and Escherichia coli is the most common urinary pathogen in the general pediatric population. Less is known of the pathogens responsible for urinary tract infections (UTI) in the pediatric SB population or their evolving antimicrobial resistance patterns. The goal of this study is to determine the epidemiology and antimicrobial resistance patterns of SB-associated urinary pathogens. METHODS Between January 1996 and August 2013, 231 patients aged 1 month to 18 years were identified with a diagnosis of SB-NB and at least one symptomatic urinary tract infection (UTI) event (Table). Two-hundred and thirty-one normally voiding children with a single symptomatic UTI were age-matched based on age at diagnosis of UTI at a 1:1 ratio. Chi-square tests and Generalized Estimating Equation analysis, controlling for clinicopathological factors, were performed to compare rates of pathogen-associations with UTI between groups and likelihood of UTI with multi-drug resistant (MDR) organisms. RESULTS Children in the SB-NB group had a higher rate of non-E. coli UTI compared with controls (64% vs. 41%, p < 0.01), particularly associated with Klebsiella species the SB-NB group had an overall higher infection rate with MDR organisms (21% vs. 10%, p < 0.01) and E. coli isolates, with a trend towards increased rates of antibiotic resistance to aminoglycosides, fluoroquinolones, cephalosporins, extended spectrum β-lactams, and TMP-SMZ. Additionally, patients in the SB-NB group had a 10-fold increase of urosepsis with 57% of events caused by MDR organisms. CONCLUSIONS Children with SB-NB are more likely to have non-E. coli UTI, UTIs with MDR organisms, and urosepsis than the general pediatric population.

Continuous low-dose antibiotic prophylaxis for adults with repeated urinary tract infections (AnTIC): a randomised, open-label trial. THE LANCET. INFECTIOUS DISEASES 2018; 18:957-968. [PMID: 30037647 PMCID: PMC6105581 DOI: 10.1016/s1473-3099(18)30279-2] [Citation(s) in RCA: 60] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/06/2018] [Revised: 03/27/2018] [Accepted: 04/20/2018] [Indexed: 12/17/2022]
Abstract
BACKGROUND Repeated symptomatic urinary tract infections (UTIs) affect 25% of people who use clean intermittent self-catheterisation (CISC) to empty their bladder. We aimed to determine the benefits, harms, and cost-effectiveness of continuous low-dose antibiotic prophylaxis for prevention of recurrent UTIs in adult users of CISC. METHODS In this randomised, open-label, superiority trial, we enrolled participants from 51 UK National Health Service organisations. These participants were community-dwelling (as opposed to hospital inpatient) users of CISC with recurrent UTIs. We randomly allocated participants (1:1) to receive either antibiotic prophylaxis once daily (prophylaxis group) or no prophylaxis (control group) for 12 months by use of an internet-based system with permuted blocks of variable length. Trial and laboratory staff who assessed outcomes were masked to allocation but participants were aware of their treatment group. The primary outcome was the incidence of symptomatic, antibiotic-treated UTIs over 12 months. Participants who completed at least 6 months of follow-up were assumed to provide a reliable estimate of UTI incidence and were included in the analysis of the primary outcome. Change in antimicrobial resistance of urinary and faecal bacteria was monitored as a secondary outcome. The AnTIC trial is registered at ISRCTN, number 67145101; and EudraCT, number 2013-002556-32. FINDINGS Between Nov 25, 2013, and Jan 29, 2016, we screened 1743 adult users of CISC for eligibility, of whom 404 (23%) participants were enrolled between Nov 26, 2013, and Jan 31, 2016. Of these 404 participants, 203 (50%) were allocated to receive prophylaxis and 201 (50%) to receive no prophylaxis. 1339 participants were excluded before randomisation. The primary analysis included 181 (89%) adults allocated to the prophylaxis group and 180 (90%) adults in the no prophylaxis (control) group. 22 participants in the prophylaxis group and 21 participants in the control group were not included in the primary analysis because they were missing follow-up data before 6 months. The incidence of symptomatic antibiotic-treated UTIs over 12 months was 1·3 cases per person-year (95% CI 1·1-1·6) in the prophylaxis group and 2·6 (2·3-2·9) in the control group, giving an incidence rate ratio of 0·52 (0·44-0·61; p<0·0001), indicating a 48% reduction in UTI frequency after treatment with prophylaxis. Use of prophylaxis was well tolerated: we recorded 22 minor adverse events in the prophylaxis group related to antibiotic prophylaxis during the study, predominantly gastrointestinal disturbance (six participants), skin rash (six participants), and candidal infection (four participants). However, resistance against the antibiotics used for UTI treatment was more frequent in urinary isolates from the prophylaxis group than in those from the control group at 9-12 months of trial participation (nitrofurantoin 12 [24%] of 51 participants from the prophylaxis group vs six [9%] of 64 participants from the control group with at least one isolate; p=0·038), trimethoprim (34 [67%] of 51 vs 21 [33%] of 64; p=0·0003), and co-trimoxazole (26 [53%] of 49 vs 15 [24%] of 62; p=0·002). INTERPRETATION Continuous antibiotic prophylaxis is effective in reducing UTI frequency in CISC users with recurrent UTIs, and it is well tolerated in these individuals. However, increased resistance of urinary bacteria is a concern that requires surveillance if prophylaxis is started. FUNDING UK National Institute for Health Research.

Abstract
OBJECTIVE To examine the effects of bowel management on the frequency of urinary infections in spina bifida patients. STUDY DESIGN The research was carried out from 2014 to 2017, with the recruitment process from June 2014 to March 2016. The first group consisted of 35 patients who were administered bowel management combined with anticholinergic medication therapy and clean intermittent catheterization (CIC). The second group consisted of 35 patients who were treated only with anticholinergic medication therapy and CIC. Bowel management included daily enema, laxative application, and a special diet, with a view to treating constipation that was estimated on the basis of Roma III criteria and echosonographically determined transversal rectal diameter. The effects of the administered bowel management on urinary infections were estimated on the basis of the number of urinary infections before and after the administered therapy. The observation period of every patient was 1 year. RESULTS There were no significant statistical differences regarding age, gender, and baseline clinical features between the two groups. In the group treated with bowel management combined with anticholinergic medication therapy and CIC, the average number of urinary infections was 0.3 ± 0.5 SD, whereas in the group treated exclusively with anticholinergic medication therapy and CIC the average number of urinary infections was 1.1 ± 1.0 SD. There was a statistical difference regarding urinary infections, that is the average number of urinary infections between these two groups of patients (p < 0.001). CONCLUSION Administering bowel management considerably decreases the frequency of urinary infections, and should form an integral part of treatment of spina bifida patients.

Abstract
PURPOSE To evaluate perioperative management for the prevention of postoperative shunt infection and malfunction after intraperitoneal urological surgery in patients with myelodysplasia and a ventriculoperitoneal shunt. METHODS From 2005 to 2015, 20 consecutive patients with myelodysplasia and a ventriculoperitoneal shunt who underwent intraperitoneal urological surgeries were managed with the same perioperative regimen. Intraperitoneal surgeries involved opening gastrointestinal tracts, including bladder augmentation by enterocystoplasty, creating continent catheterizable channels and Malone antegrade continent enema. We compared results with those from seven previous reports regarding postoperative shunt complications, surgical histories of previous shunt revisions, management of bacteriuria before surgery preoperative bowel preparation, antibiotic regimens, and duration of indwelling drain. RESULTS Of 20 patients, 18 received prior shunt revisions, and 14 had positive urine culture before surgery that was managed with oral antibiotics. Thirteen patients underwent bladder augmentation with ileum, and one underwent augmentation with sigmoid colon. Nineteen patients underwent Malone antegrade continent enema using the appendix. All parenteral antibiotics were stopped on postoperative day 2.5. Mean duration of indwelling peritoneal drain was 2.7days. Mean follow-up period was 59.8months. Neither postoperative shunt infections nor intraperitoneal shunt malfunctions were recognized during follow-up period. CONCLUSIONS This is the first study to evaluate postoperative ventriculoperitoneal shunt complications in patients with myelodysplasia who underwent intraperitoneal urological surgeries with a specific perioperative regimen. Shunt complications are greatly reduced by rigorous perioperative management, including preoperative control of bacteriuria, appropriate administration of prophylactic antibiotics, and early removal of intraperitoneal drains. LEVELS OF EVIDENCE The type of study: Case series with no comparison group, IV.

Abstract
Background Bacterial resistance to antibiotics is an increasingly threatening consequence of antimicrobial exposure for many decades now. In urinary tract infections (UTIs), antibiotic prophylaxis (AP) increases bacterial resistance. We studied the resistance patterns of positive urinary cultures in spina bifida children on clean intermittent catheterization, both continuing and stopping AP. Methods In a cohort of 176 spina bifida patients, 88 continued and 88 stopped using AP. During 18 months, a fortnightly catheterized urine sample for bacterial pathogens was cultured. UTIs and significant bacteriuria (SBU) were defined as a positive culture with a single species of bacteria, respectively with and without clinical symptoms and leukocyturia. We compared the percentage of resistance to commonly used antibiotics in the isolated bacteria in both groups. Results In a total of 4917 cultures, 713 (14.5%) had a positive monoculture, 54.3% of which were Escherichia coli. In the group stopping AP, the resistance percentage to antibiotics in UTI / SBU bacteria was lower than in the group remaining on AP, even when excluding the administered prophylaxis. Conclusion Stopping antibiotic prophylaxis for urinary tract infections is associated with reduced bacterial resistance to antibiotics in children with spina bifida.

Abstract
OBJECTIVE To identify risk factors for recurrent urinary tract infection (UTI) in patients who perform clean intermittent catheterization (CIC). METHODS A 6-year retrospective chart review of patients with spina bifida or tethered cord who perform clean intermittent catheterization (8 months to 58 years) was conducted. A strict case definition for UTI was applied, and per-subject UTI events, demographic, and clinical data were abstracted. Data were compared between groups defined by no or infrequent UTI (≤1.0 UTI/study year) and frequent UTI (>1.0 UTI/study year). RESULTS Of 194 total patients, 146 (75%) had no UTIs or infrequent UTIs, and 48 (25%) patients had frequent UTIs. On univariate analysis, only younger age and suprasacral cord lesions were associated with frequent UTIs (P = .002 and P = .007, respectively). Among the 128 patients with urodynamic studies, bladder capacity, compliance, detrusor overactivity, and detrusor leak point pressure were not associated with frequent UTI on univariate analysis. On multivariate analysis, increasing age was found to be associated with decreased odds of UTI by 7% per year (odds ratio 0.93, P = .016). CONCLUSION The risk of UTI among individuals with spina bifida or tethered cord declines with increasing age. Bladder function based on urodynamic parameters did not correlate with frequent UTIs.

Abstract
Background Spina bifida increases the risk for urinary tract infections (UTI). Antimicrobial prophylaxis (AP) reduces symptomatic UTI’s but selects resistant organisms. Measures to ensure regular and complete emptying of the bladder combined with treatment of constipation reduce the risk for UTI. Objectives Demonstrate that close adherence to a catheterization regimen in children with spina bifida (Selective Treatment - ST) reduces the need for antimicrobial prophylaxis. Methods Case series analysis of pediatric spina bifida clinic patients where routine antimicrobial prophylaxis was replaced by clean-catch catheterization and daily bowel regimen (ST). Retrospective chart review of 67 children (mean entry age: 24 months, median age: 4 months; 32 Males, 35 Females) enrolled between 1986 - 2004. Mean follow-up was 128.6 months (range 3 - 257 months). Asymptomatic and symptomatic UTI incidences were noted on AP and ST protocols. Creatinine clearance at study entry and follow-up was calculated by the age appropriate method. A multivariable regression model with delta Glomerular Filtration Rate (GFR) as the dependent variable, independent sample t-test and Wilcoxon rank sum were performed with SAS v. 9.2. Results The mean number of infections while on AP was 8.7 (95% CI 5.72, 11.68) and was 1.0 on ST (95% CI 0.48, 1.43). 5 infections on the AP protocol required intravenous (IV) antibiotics due to resistance to oral therapy, but none on ST. Comparing change in GFR between both protocols (AP vs. ST) found a significant difference in the change of GFR by treatment protocol. Conclusions AP did not prevent UTIs and resulted in more resistant organisms requiring IV antibiotics. Discontinuing AP allowed the return of susceptibility to oral antimicrobials and significantly improved GFR in those children who had previously been on AP. Adherence to a catheterization regimen with prompt treatment of symptomatic UTI conserved renal function and prevented selection of resistant organisms.

Antibiotic treatment for intermittent bladder catheterisation with once daily prophylaxis (the AnTIC study): Study protocol for a randomised controlled trial. Trials 2016; 17:276. [PMID: 27259552 PMCID: PMC4893270 DOI: 10.1186/s13063-016-1389-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2015] [Accepted: 05/11/2016] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Clean intermittent self-catheterisation is an important management option for people who cannot empty their bladder effectively. Recurrent urinary tract infections are common in these patients. Data from recent studies suggest that antibiotic prophylaxis may be beneficial in reducing infection risk, but the effectiveness of this intervention remains uncertain. METHODS/DESIGN This is a 52-site, patient randomised superiority trial set in routine care comparing an experimental strategy of once daily antibiotic prophylaxis for 12 months against a control strategy of no prophylaxis in people who carry out self-catheterisation and suffer recurrent urinary tract infections. The primary outcome is number of urinary tract infections during a 12-month treatment period. Both groups will otherwise receive usual care including on demand treatment courses of antibiotics for urinary tract infection. Participants and their clinicians will not be blinded to the allocated intervention, but central trial staff managing and analysing trial data will, as far as possible, be unaware of participant allocation. The analysis will follow intention-to-treat principles. DISCUSSION This trial was commissioned and funded by the United Kingdom National Health Service following prioritisation of the research question by the National Institute for Health and Care Excellence. TRIAL REGISTRATION ISRCTN67145101 EUDRACT2013-002556-32. Registered on 25 October 2013.

Abstract
AIM In this study, it was aimed to evaluate the frequency of significant bacteriuria and antibiotic resistance characteristics in children with myelodysplasia in whom clean intermittent catheterization was administered. MATERIAL AND METHODS The study group was composed of 71 patients with myelodysplasia who were found to have significant bacteriuria (age: 8.20±4.57 years; 39 girls) and the control groups was composed of 49 children who were diagnosed with community-acquired urinary tract infection (age: 7.94±4.17 years; 29 girls). The patient and control groups were evaluated in terms of the microorganisms grown in urinary cultures and antibiotic resistance characteristics. The study approved by the ethics committe (14/02/2012-19/E). RESULTS Growth of Escherichia coli (E. coli) was found with the highest rate in myelodysplasic patients. However, when compared with the control group in terms of microorganism types, an increase in the growth rates of the microorganisms excluding E. coli was observed in the patients with myelodysplasia which was close to the significance limit (p=0.055). When antibiotic resistance properties were examined, a significantly increased resistance against cotrimaxazole was found in the patient group compared to the control group (p=0.001). 84.5% of the patients were using prophylactic antibiotic including mainly co-trimoxazole. A significantly increased co-trimoxazole resistance was also found in the patients who were using prophylactic antibiotic compared to the patients who were not using prophylactic antibiotic (p=0.025). The rate of symptomatic UTI was found to be 21% in the patients with myelodysplasia and a significant increase was found in the complaints of abdominal/side pain and nausea/vomiting as well as fever in these patients compared to the patients with asymptomatic bacteriuria (p=0.029 and p=0.032, respectively). CONCLUSION Our results show that UTI is still a significant problem in patients with myelodysplasia. In addition, they show that use of prophylactic antibiotic may increase the frequency of development of resistance and co-trimoxazole used for this objective is not a good option..

Abstract
Background Significant bacteriuria (SBU) and urinary tract infections (UTIs) are common in patients with spina bifida and neuropathic detrusor sphincter dysfunction. Laboratory agar plated culture is the gold standard to establish SBU. It has the disadvantage of diagnostic and subsequent therapeutic delay. Leukocyte esterase tests (LETs) and dip slides proved to be useful in the general populations to exclude SBU and UTI. The aim of this study was to evaluate the reliability of LET and dip slide in children with spina bifida without symptoms of UTI. The reliability in children with asymptomatic SBU was not studied before. Methods In one hundred and twelve children with spina bifida on clean intermittent catheterization LETs and dip slides were compared with laboratory cultures. Both tests and agar plated cultures were performed on catheterized urine samples. The hypothesis was that the home tests are as accurate as laboratory cultures. Results A SBU was found in 45 (40%) of the 112 laboratory cultures. A negative LET excluded SBU (negative predictive value 96%), while a positive LET had a positive predictive value of 72%. The false positive rate was 28%. Dip slide determination of bacterial growth had no added value, other than serving as transport medium. Conclusions In spina bifida children, leukocyte esterase testing can be used to exclude significant bacteriuria at home, while dip slide tests have no added value to diagnose or exclude significant bacteriuria.

Abstract
Urinary tract infections (UTIs) represent one of the most commonly acquired diseases among the general population as well as hospital in-patients, yet remain difficult to effectively and consistently treat. High rates of recurrence, anatomic abnormalities, and functional disturbances of the urinary tract all contribute to the difficulty in management of these infections. However, recent advances reveal important molecular and genetic factors that contribute to bacterial invasion and persistence in the urinary tract, particularly for the most common causative agent, uropathogenic Escherichia coli. Recent studies using animal models of experimental UTIs have recently provided mechanistic insight into the clinical observations that question the effectiveness of antibiotic therapy in treatment. Ultimately, continuing research will be necessary to identify the best targets for effective treatment of this costly and widespread infectious disease.

Abstract
BACKGROUND People requiring long-term bladder draining commonly experience catheter-associated urinary tract infection and other problems. OBJECTIVES To determine if certain catheter policies are better than others in terms of effectiveness, complications, quality of life and cost-effectiveness in long-term catheterised adults and children. SEARCH METHODS We searched the Cochrane Incontinence Group Specialised Trials Register (searched 28 September 2011). Additionally, we examined all reference lists of identified trials. SELECTION CRITERIA All randomised and quasi-randomised trials comparing catheter policies (route of insertion and use of antibiotics) for long-term (more than 14 days) catheterisation in adults and children. DATA COLLECTION AND ANALYSIS Data were extracted by two reviewers independently and compared. Disagreements were resolved by discussion. Data were processed as described in the Cochrane Handbook. If the data in trials had not been fully reported, clarification was sought from the authors. When necessary, the incidence-density rates (IDR) and/or the incidence-density differences (IDD) within a certain time period were calculated. MAIN RESULTS Eight trials met the inclusion criteria involving 504 patients in four cross-over and four parallel-group randomised controlled trials. Only two of the pre-stated six comparisons were addressed in these trials. Four trials compared antibiotic prophylaxis with antibiotics when clinically indicated. For patients using intermittent catheterisation, there were inconsistent findings about the effect of antibiotic prophylaxis on symptomatic urinary tract infection (UTI). Only one study found a significant difference in the frequency of UTI favouring prophylaxis. For patients using indwelling urethral catheterisation, one small trial reported fewer episodes of symptomatic UTI in the prophylaxis group.Four trials compared antibiotic prophylaxis with giving antibiotics when microbiologically indicated. For patients using intermittent catheterisation, there was limited evidence that receiving antibiotics reduced the rate of bacteriuria (asymptomatic and symptomatic). There was weak evidence that prophylactic antibiotics were better in terms of fewer symptomatic bacteriuria. AUTHORS' CONCLUSIONS No eligible trials were identified that compared alternative routes of catheter insertion. The data from eight trials comparing different antibiotic policies were sparse, particularly when intermittent catheterisation was considered separately from indwelling catheterisation. Possible benefits of antibiotic prophylaxis must be balanced against possible adverse effects, such as development of antibiotic resistant bacteria. These cannot be reliably estimated from currently available trials.

Relationship among bacterial virulence, bladder dysfunction, vesicoureteral reflux and patterns of urinary tract infection in children. J Urol 2012; 188:236-41. [PMID: 22595065 DOI: 10.1016/j.juro.2012.03.025] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2011] [Indexed: 11/22/2022]
Abstract
PURPOSE We hypothesized that virulence levels of Escherichia coli isolates causing pediatric urinary tract infections differ according to severity of infection and also among various uropathies known to contribute to pediatric urinary tract infections. We evaluated these relationships using in vitro cytokine interleukin-6 elicitation. MATERIALS AND METHODS E. coli isolates were cultured from children presenting with urinary tract infections. In vitro cytokine (interleukin-6) elicitation was quantified for each isolate and the bacteria were grouped according to type of infection and underlying uropathy (neurogenic bladder, nonneurogenic bowel and bladder dysfunction, primary vesicoureteral reflux, no underlying etiology). RESULTS A total of 40 E. coli isolates were collected from children with a mean age of 61.5 months (range 1 to 204). Mean level of in vitro cytokine elicitation from febrile urinary tract infection producing E. coli was significantly lower than for nonfebrile strains (p = 0.01). The interleukin-6 response to E. coli in the neurogenic bladder group was also significantly higher than in the vesicoureteral reflux (p = 0.01) and no underlying etiology groups (p = 0.02). CONCLUSIONS In vitro interleukin-6 elicitation, an established marker to determine bacterial virulence, correlates inversely with clinical urinary tract infection severity. Less virulent, high cytokine producing E. coli were more likely to cause cystitis and were more commonly found in patients with neurogenic bladder and nonneurogenic bowel and bladder dysfunction, whereas higher virulence isolates were more likely to produce febrile urinary tract infections and to affect children with primary vesicoureteral reflux and no underlying etiology. These findings suggest that bacteria of different virulence levels may be responsible for differences in severity of pediatric urinary tract infections and may vary among different underlying uropathies.
