Abstract
Blood cultures are fundamental in diagnosing and treating sepsis in the pediatric intensive care unit (PICU), but practices vary widely. Overuse can lead to false positive results and unnecessary antibiotics. Specific factors underlying decisions about blood culture use and overuse are unknown. Therefore, we aimed to identify perceived determinants of blood culture use in the PICU. Methods We conducted semistructured interviews of clinicians (M.D., D.O., R.N., N.P., P.A.) from 6 PICUs who had participated in a quality improvement collaborative about blood culture practices. We developed interview questions by combining elements of the Consolidated Framework for Implementation Research and behavioral economics. We conducted telephone interviews, open-coded the transcripts, and used modified content analysis to determine key themes and mapped themes to elements of Consolidated Framework for Implementation Research and behavioral economics. Results We reached thematic saturation in 24 interviews. Seven core themes emerged across 3 Consolidated Framework for Implementation Research domains: individual characteristics [personal belief in the importance of blood cultures, the perception that blood cultures are a low-risk test]; inner setting [adherence to site-specific usual practices, site-specific overall approach to PICU care (collaborative versus hierarchical), influence of non-PICU clinicians on blood culture decisions]; and outer setting [patient-specific risk factors, sepsis guidelines]. In addition, outcome bias, default bias, and loss aversion emerged as salient behavioral economics concepts. Conclusions Determinants of blood culture use include individual clinician characteristics, inner setting, and outer setting, as well as default bias, outcome bias, and loss aversion. These determinants will now inform the development of candidate strategies to optimize culture practices.

Abstract
INTRODUCTION Antibiotic prescription is a challenging issue in critical care settings. Different pharmacokinetic and pharmacodynamic properties, polypharmacy, drug interactions, and high incidence of multidrug-resistant microorganisms in this population can influence the selection, safety, and efficacy of prescribed antibiotics. AREAS COVERED In the current article, we searched PubMed, Scopus, and Google Scholar for estimating renal function in acute kidney injury, nephrotoxicity of commonly used antibiotics, and nephrotoxin stewardship in intensive care units. EXPERT OPINION Early estimation of kidney function with an accurate method may be helpful to optimize antimicrobial treatment in critically ill patients. Different antibiotic dosing regimens may be required for patients with acute kidney injury. In many low-resource settings, therapeutic drug monitoring is not available for antibiotics. Acute kidney injury may influence treatment effectiveness and patient outcome.

Abstract
Antimicrobial and diagnostic stewardship initiatives have become increasingly important in paediatric settings. The value of qualitative approaches to conduct stewardship work in paediatric patients is being increasingly recognized. This article seeks to provide an introduction to basic elements of qualitative study designs and provide an overview of how these methods have successfully been applied to both antimicrobial and diagnostic stewardship work in paediatric patients. A multidisciplinary team of experts in paediatric infectious diseases, paediatric critical care and qualitative methods has written a perspective piece introducing readers to qualitative stewardship work in children, intended as an overview to highlight the importance of such methods and as a starting point for further work. We describe key differences between qualitative and quantitative methods, and the potential benefits of qualitative approaches. We present examples of qualitative research in five discrete topic areas of high relevance for paediatric stewardship work: provider attitudes; provider prescribing behaviours; stewardship in low-resource settings; parents' perspectives on stewardship; and stewardship work focusing on select high-risk patients. Finally, we explore the opportunities for multidisciplinary academic collaboration, incorporation of innovative scientific disciplines and young investigator growth through the use of qualitative research in paediatric stewardship. Qualitative approaches can bring rich insights and critically needed new information to antimicrobial and diagnostic stewardship efforts in children. Such methods are an important tool in the armamentarium against worsening antimicrobial resistance, and a major opportunity for investigators interested in moving the needle forward for stewardship in paediatric patients.

Characteristics and Outcomes of Bloodstream Infections in a Tertiary-Care Pediatric Hematology-Oncology Unit: A 10-Year Study. J Clin Med 2022; 11:jcm11030880. [PMID: 35160334 PMCID: PMC8836920 DOI: 10.3390/jcm11030880] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2021] [Revised: 01/24/2022] [Accepted: 02/03/2022] [Indexed: 12/21/2022] Open
Abstract
Bloodstream infections (BSIs) after chemotherapy or hematopoietic stem cell transplantation (HSCT) are a leading cause of morbidity and mortality. Data on 154 BSIs that occurred in 111 onco-hematological patients (57 hematological malignancies, 28 solid tumors, and 26 non-malignant hematological diseases) were retrospectively collected and analyzed. Monomicrobial Gram-positive (GP), Gram-negative (GN), and fungal BSIs accounted for 50% (77/154), 38.3% (59/144), and 3.2% (5/154) of all episodes. Polymicrobial infections were 7.8% (12/154), while mixed bacterial-fungal infections were 0.6% (1/154). The most frequent GN isolates were Escherichia coli (46.9%), followed by Pseudomonas aeruginosa (21.9%), Klebsiella species (18.8%), and Enterobacter species (6.3%). Overall, 18.8% (12/64) of GN organisms were multidrug-resistant (seven Escherichia coli, three Klebsiella pneumoniae, and two Enterobacter cloacae), whereas GP resistance to glycopeptides was observed in 1% (1/97). Initial empirical antibiotic therapy was deemed inappropriate in 12.3% of BSIs (19/154). The 30-day mortality was 7.1% (11/154), while the bacteremia-attributable mortality was 3.9% (6/154). In multivariate analysis, septic shock was significantly associated with 30-day mortality (p = 0.0001). Attentive analysis of epidemiology and continuous microbiological surveillance are essential for the appropriate treatment of bacterial infections in pediatric onco-hematological patients.

Abstract
Especially critically ill children are exposed to antibiotic overtreatment, mainly caused by the fear of missing out a severe bacterial infection. Potential adverse effects and selection of multi-drug resistant bacteria play minor roles in decision making. This narrative review first describes harm from antibiotics and second focuses on different aspects that could help to reduce antibiotic overtreatment without harming the patient: harm from antibiotic treatment, diagnostic approaches, role of biomarkers, timing of antibiotic therapy, empiric therapy, targeted therapy, and therapeutic drug monitoring. Wherever possible, we linked the described evidence to the current Surviving Sepsis Campaign guidelines. Antibiotic stewardship programs should help guiding antibiotic therapy for critically ill children. IMPACT: Critically ill children can be harmed by inadequate or overuse of antibiotics. Hemodynamically unstable children with a suspicion of infection should be immediately treated with broad-spectrum antibiotics. In contrast, in hemodynamically stable children with sepsis and organ dysfunction, a time frame of 3 h for proper diagnostics may be adequate before starting antibiotics if necessary. Less and more targeted antibiotic treatment can be achieved via antibiotic stewardship programs.

Abstract
OBJECTIVE Our study aimed to describe the use of aminoglycosides (AGs) in the pediatric population in acute settings and to assess its compliance with the most recent national recommendations. METHODS A single-center retrospective study conducted over a 5-month period. Pediatric patients who received at least one dose of AGs in emergency or intensive care unit were included. Compliance with the 2011 French recommendations was assessed. RESULTS A total of 153 AG prescriptions (120 with gentamicin and 33 with amikacin) for 139 patients (median age of patients = 10 months [IQR: 3-36]) were analyzed. Most of the AG prescriptions were initiated in the emergency department (n = 117, 76%) and, overall, compliance with national guidelines was met in half (n = 77) of the prescriptions. In the emergency department, cases of misuse concerned the indication, mostly for patients with pyelonephritis. In the pediatric intensive care unit setting, the misuse concerned underdosing and a low rate of pharmacological monitoring. CONCLUSION AGs are still misused in pediatric acute settings. In order to limit drug resistance and to be more efficacious, higher doses should be used and monitoring should be performed, in particular in pediatric intensive care units. In the emergency department, more objective criteria should be used to initiate AGs.

Abstract
INTRODUCTION Sufficient empirical antimicrobial therapy in febrile patients with cancer is challenging, owing to the limited arsenal of available antibiotics in an era of growing resistance. Because of the emergence of gram-negative bacteria resistant to ceftazidime and piperacillin, a combination antibiotic therapy was employed that uses meropenem combined with gentamicin and/or vancomycin if the patient further deteriorates. METHODS A retrospective cohort analysis was performed including all patients with catheter-associated bloodstream infections (BSIs) and treated for childhood cancer in a tertiary single centre between 1 January 2000 and 31 June 2018. We calculated the prevalence and the risk for BSIs and compared the in vitro susceptibility to various antimicrobial agents. RESULTS Of 653 patients with childhood cancer, 113 patients (17.3%) were identified with a total of 139 BSIs, most of them occurring in patients with leukaemia (n = 90, 64.7%) and were associated with gram-positive bacteria (60.5%). In our cohort, all BSIs with gram-negative bacteria exhibited in vitro susceptibility against meropenem alone without any signs of resistance development. The antibiotic coverage of our meropenem-based combination therapy was also highly effective for gram-positive and non-fermenting bacteria. Thus, BSI-related mortality in all 139 BSI episodes was 1.4%. Clostridium difficile infections (CDIs), as main adverse event of carbapenem usage, occurred in only 16 (2.5%) patients. CONCLUSION Our meropenem-based combination therapy showed sufficient empirical antibiotic coverage in the majority of BSIs (96.4%) and did not result in an increased rate of unwanted side effects or development of antibiotic resistance.

Abstract
BACKGROUND Healthcare-associated infections (HAIs) are considered a major threat to public health resulting in significant morbidity, mortality, and additional costs. The present study aimed to assess the current patterns and risk factors of HAIs among hospitalized children. MATERIALS AND METHODS Three repeated point prevalence surveys were conducted in the pediatric inpatients of four hospitals by using the methodology developed by the European Center for Disease Prevention and Control. All patients present in the ward at 8:00 AM on the survey day and not discharged from the hospital on the same day were included. A standardized data collection form containing information on the presence of HAIs and the associated risk factors was completed for the patients. FINDINGS Out of 888 hospitalized patients, 116 (13.1%) had the symptoms of HAIs. Most common infections were bloodstream infections (BSIs) (32.8%), pneumonia (21.0%), ear, eyes, nose and throat infections (11.8%), and skin and soft tissue infections (SSTs) (19.0%). Factors significantly associated with infections were the length of hospital stay (p = 0.000), admission to the medicine ward (p = 0.034), and male gender (p = 0.010). BSIs were most common in children belonging to the age group of less than one month (78.9%), who were admitted to intensive care units (73.7%). SSTs including surgical site infections were more prevalent in surgery wards (78.3%). CONCLUSIONS A high rate of HAIs among pediatrics was found in Pakistan. Infection control and prevention strategies are needed with a major focus on interventions to prevent the spread of most prevalent HAIs.

Abstract
ZusammenfassungDie antibiotische Therapie stellt eine wichtige und in vielen Fällen unverzichtbare Maßnahme zum Erreichen einer Restitutio ad integrum bei bakteriellen Infektionen dar. Hierdurch können auch schwere Infektionen bei immungeschwächten Patienten geheilt werden. Wir wissen heute aber auch, dass insbesondere kritisch kranke Kinder häufig inadäquat antibiotisch behandelt werden – mit ebenfalls potenziell schädlichen Nebenwirkungen. In diesem Spannungsfeld aus kritisch krankem Kind, der Angst, etwas zu verpassen, und potenzieller Übertherapie ist es oft nicht einfach, eine rationale Therapieentscheidung zu fällen. Im vorliegenden Review werden aktuelle Studien zu wichtigen Aspekten der antibiotischen Therapie bei kritisch kranken Kindern beleuchtet und im Hinblick auf klinische Umsetzbarkeit interpretiert. Folgende Teilaspekte werden besprochen: 1) Zeitpunkt der antibiotischen Therapie und Möglichkeiten eines abwartenden Verhaltens, 2) die Auswahl der Antibiotika in der empirischen Therapie, 3) Deeskalationsstrategien und 4) die Dauer der antibiotischen Therapie. Antibiotic-Stewardship-Programme, unter Einbeziehung von pädiatrischen Infektiologen, klinischen Pharmazeuten und Mikrobiologen, spielen bei den häufig schwierigen klinischen Entscheidungen eine entscheidende Rolle.

Abstract
Aminoglycosides are commonly prescribed to children with febrile neutropenia (FN) but their impact on clinical outcomes is uncertain and extent of guideline compliance is unknown. We aimed to review aminoglycoside prescription and additional antibiotic prescribing, guideline compliance and outcomes for children with FN. We analysed data from the Australian Predicting Infectious ComplicatioNs in Children with Cancer (PICNICC) prospective multicentre cohort study, in children <18 years with FN between November 2016 and January 2018. Impact of aminoglycoside use in the first 12 hours of FN on composite unfavourable outcome of death, ICU admission, relapse of infection or late-onset sepsis was assessed using multivariable Cox regression. The study was conducted in Australia where antimicrobial resistance among gram negative organisms is relatively low. Data from 858 episodes of FN in 462 children from 8 centres were assessed, median age 5.8 years (IQR 3.5-10.8 years). Early empiric aminoglycosides were prescribed in 255 episodes (29.7%). Guideline non-compliance was common: in 46% (184/400) of eligible episodes, patients did not receive aminoglycosides, while aminoglycosides were prescribed in 9% (39/458) of guideline-ineligible episodes. Adjusted hazard of the composite unfavourable outcome was 3.81 times higher among patients prescribed empiric aminoglycosides than among those who weren't (95% confidence interval, 1.89-7.67), with no increased risk of unfavourable outcome in eligible patients who did not receive aminoglycosides. In a large paediatric FN cohort, aminoglycoside prescription was common and was often non-compliant with guidelines. There was no evidence for improved outcome with aminoglycosides, even in those who met guideline criteria, within a low-resistance setting. Empiric aminoglycoside prescription for children with FN requires urgent review in guidelines and in national practice.

Abstract
OBJECTIVES To develop evidence-based recommendations for clinicians caring for children (including infants, school-aged children, and adolescents) with septic shock and other sepsis-associated organ dysfunction. DESIGN A panel of 49 international experts, representing 12 international organizations, as well as three methodologists and three public members was convened. Panel members assembled at key international meetings (for those panel members attending the conference), and a stand-alone meeting was held for all panel members in November 2018. A formal conflict-of-interest policy was developed at the onset of the process and enforced throughout. Teleconferences and electronic-based discussion among the chairs, co-chairs, methodologists, and group heads, as well as within subgroups, served as an integral part of the guideline development process. METHODS The panel consisted of six subgroups: recognition and management of infection, hemodynamics and resuscitation, ventilation, endocrine and metabolic therapies, adjunctive therapies, and research priorities. We conducted a systematic review for each Population, Intervention, Control, and Outcomes question to identify the best available evidence, statistically summarized the evidence, and then assessed the quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation approach. We used the evidence-to-decision framework to formulate recommendations as strong or weak, or as a best practice statement. In addition, "in our practice" statements were included when evidence was inconclusive to issue a recommendation, but the panel felt that some guidance based on practice patterns may be appropriate. RESULTS The panel provided 77 statements on the management and resuscitation of children with septic shock and other sepsis-associated organ dysfunction. Overall, six were strong recommendations, 49 were weak recommendations, and nine were best-practice statements. For 13 questions, no recommendations could be made; but, for 10 of these, "in our practice" statements were provided. In addition, 52 research priorities were identified. CONCLUSIONS A large cohort of international experts was able to achieve consensus regarding many recommendations for the best care of children with sepsis, acknowledging that most aspects of care had relatively low quality of evidence resulting in the frequent issuance of weak recommendations. Despite this challenge, these recommendations regarding the management of children with septic shock and other sepsis-associated organ dysfunction provide a foundation for consistent care to improve outcomes and inform future research.

Abstract
BACKGROUND Community-acquired Gram-Negative (GN) bacteremia caused more morbidity and mortality recently in children. The increasing drug resistance was also an important issue. However, published reference was few about children. METHODS We conducted a retrospective study to collect febrile patients with blood culture from a pediatric emergency department during 2007∼2013, and exclude cases ever admitted to hospital within 14 days. These blood cultures all showed single GN organism. The demographic characteristics of enrolled patients and the antibiogram of pathogens were recorded, and then were compared statistically to find out the immediate and appropriate antibiotics. RESULTS Total 143 sets of blood culture were GN bacilli and the median age of cases was 2 (IQR, 1-5) years old. Male gender was predominant. Non-fermenting Gram-negative bacilli group (NFGNB spp.), Salmonella spp. and Escherichia coli were first three common pathogens respectively. However, total 37 cases of NFGNB spp. other than Pseudomonas aeruginosa were the possible pathogens. By multiple logistic regression analysis, lower hemoglobin and higher alanine aminotransferase were significant difference between common pathogens and possible ones. Besides, the prevalent age regarding resistant strains of Escherichia coli and Pseudomonas aeruginosa were both focused on less than 1 year old. However, Salmonella spp. were prevalent in the age from 1 to 3 years old. CONCLUSIONS For different age groups, Salmonella spp. and Escherchia coli were the most common pathogens of community-acquired GN bacteremia. For infants, Pseudomonas aeruginosa sepsis and resistant strain of Escherchia coli should be alert, and broader antibiotics should be considered.

Abstract
Machine learning is a branch of computer science that has the potential to transform epidemiologic sciences. Amid a growing focus on "Big Data," it offers epidemiologists new tools to tackle problems for which classical methods are not well-suited. In order to critically evaluate the value of integrating machine learning algorithms and existing methods, however, it is essential to address language and technical barriers between the two fields that can make it difficult for epidemiologists to read and assess machine learning studies. Here, we provide an overview of the concepts and terminology used in machine learning literature, which encompasses a diverse set of tools with goals ranging from prediction to classification to clustering. We provide a brief introduction to 5 common machine learning algorithms and 4 ensemble-based approaches. We then summarize epidemiologic applications of machine learning techniques in the published literature. We recommend approaches to incorporate machine learning in epidemiologic research and discuss opportunities and challenges for integrating machine learning and existing epidemiologic research methods.

Antipseudomonal monotherapy or combination therapy for older adults with community-onset pneumonia and multidrug-resistant risk factors: a retrospective cohort study. Am J Infect Control 2019; 47:1053-1058. [PMID: 30904374 PMCID: PMC6710104 DOI: 10.1016/j.ajic.2019.02.018] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2019] [Revised: 02/13/2019] [Accepted: 02/14/2019] [Indexed: 11/19/2022]
Abstract
BACKGROUND Infectious Diseases Society of America guidelines recommend empiric antipseudomonal combination therapy when Pseudomonas is suspected. However, combination antipseudomonal therapy is controversial. This study compares all-cause 30-day mortality in older patients who received antipseudomonal monotherapy (PMT) or antipseudomonal combination therapy (PCT) for the treatment of community-onset pneumonia. METHODS This population-based, retrospective cohort study used data from over 150 Veterans Health Administration hospitals. Patients were classified as being at low, medium, or high risk of drug-resistant pathogens. In total, 31,027 patients were assigned to PCT or PMT treatment arms based on antibiotics received in the first 48 hours of hospital admission. RESULTS The unadjusted 30-day mortality difference between PCT and PMT was most pronounced in the low-risk group (18% vs 8%), followed by the medium-risk group (24% vs 18%) and then the high-risk group (39% vs 33%). PCT was associated with higher 30-day mortality than PMT overall (adjusted odds ratio [aOR], 1.54; 95% confidence interval [CI], 1.43-1.66) in all 3 risk groups: low (aOR, 1.69; 95% CI, 1.50-1.89), medium (aOR, 1.30; 95% CI, 1.14-1.48), and high (aOR, 1.21; 95% CI, 1.04-1.40). CONCLUSIONS Older adults who received combination antipseudomonal therapy for community-onset pneumonia fared worse than those who received monotherapy. Empiric combination antipseudomonal therapy should not be routinely offered to all patients suspected of having pseudomonal pneumonia.

Abstract
BACKGROUND This study was conducted to assess the variation in prescription practices for systemic antimicrobial agents used for prophylaxis among pediatric patients hospitalized in 41 countries worldwide. METHODS Using the standardized Antibiotic Resistance and Prescribing in European Children Point Prevalence Survey protocol, a cross-sectional point-prevalence survey was conducted at 226 pediatric hospitals in 41 countries from October 1 to November 30, 2012. RESULTS Overall, 17693 pediatric patients were surveyed and 36.7% of them received antibiotics (n = 6499). Of 6818 inpatient children, 2242 (32.9%) received at least 1 antimicrobial for prophylactic use. Of 11899 prescriptions for antimicrobials, 3400 (28.6%) were provided for prophylactic use. Prophylaxis for medical diseases was the indication in 73.4% of cases (2495 of 3400), whereas 26.6% of prescriptions were for surgical diseases (905 of 3400). In approximately half the cases (48.7% [1656 of 3400]), a combination of 2 or more antimicrobials was prescribed. The use of broad-spectrum antibiotics (BSAs), which included tetracyclines, macrolides, lincosamides, and sulfonamides/trimethoprim, was high (51.8% [1761 of 3400]). Broad-spectrum antibiotic use for medical prophylaxis was more common in Asia (risk ratio [RR], 1.322; 95% confidence interval [CI], 1.202-1.653) and more restricted in Australia (RR, 0.619; 95% CI, 0.521-0.736). Prescription of BSA for surgical prophylaxis also varied according to United Nations region. Finally, a high percentage of surgical patients (79.7% [721 of 905]) received their prophylaxis for longer than 1 day. CONCLUSIONS A high proportion of hospitalized children received prophylactic BSAs. This represents a clear target for quality improvement. Collectively speaking, it is critical to reduce total prophylactic prescribing, BSA use, and prolonged prescription.

Combination therapy with ciprofloxacin and third-generation cephalosporin versus third-generation cephalosporin monotherapy in Escherichia coli meningitis in infants: a multicentre propensity score-matched observational study. Clin Microbiol Infect 2018; 25:1006-1012. [PMID: 30593862 DOI: 10.1016/j.cmi.2018.12.026] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2018] [Revised: 12/18/2018] [Accepted: 12/19/2018] [Indexed: 11/24/2022]
Abstract
OBJECTIVES Escherichiacoli is the second cause of bacterial meningitis in neonates. Despite the use for 35 years of third-generation cephalosporins (3GCs), high morbidity and mortality rates with E. coli meningitis continue to occur. Because ciprofloxacin has good microbiologic activity against E. coli and good penetration in cerebrospinal fluid and brain, some authors have suggested adding ciprofloxacin to a 3GC regimen. The objective of this study was to assess combining 3GCs with ciprofloxacin versus 3GCs alone in a cohort of infants with E. coli meningitis. METHODS We included all cases of E. coli meningitis diagnosed in infants <12 months of age that were prospectively collected through the French paediatric meningitis surveillance network between 2001 and 2016. The main outcome was the proportion of short-term neurologic complications with versus without ciprofloxacin. The analysis was conducted retrospectively by multivariable regression and propensity score (PS) analysis. RESULTS Among the 367 infants enrolled, 201 (54.8%) of 367 had ciprofloxacin and 3GC cotreatment and 166 (45.2%) of 367 only a 3GC. Median age and weight were 15 days (range, 1-318 days) and 3.42 kg (range, 0.66-9.4 kg). A total of 86 (23.4%) of 367 infants presented neurologic complications (seizures, strokes, empyema, abscesses, hydrocephalus, arachnoiditis); 57 received ciprofloxacin cotreatment. Complications were associated with ciprofloxacin cotreatment on multivariable analysis (odds ratio (OR) = 1.9; 95% confidence interval (CI), 1.1-3.4) and PS analysis (OR = 1.9; 95% CI, 1.1-3.3). Mortality rate did not differ with and without ciprofloxacin: 22 (10.9%) of 201 versus 16 (9.6%) of 166 deaths (OR = 0.7; 95% CI, 0.3-1.6; PS analysis). CONCLUSIONS Ciprofloxacin added to 3GCs at least offers no advantage for neurologic outcome and mortality in infants with E. coli meningitis.

Patients and methods Retrospective review of consecutive patients treated with piperacillin, meropenem or flucloxacillin who underwent therapeutic drug monitoring (TDM) at St Vincent's Hospital (Sydney, Australia) between January 2013 and December 2015. Adverse events investigated included neurotoxicity, nephrotoxicity, hepatotoxicity and opportunistic Clostridium difficile infection. Toxicity was measured using observational grading criteria, clinical assessment and relevant serum biomarkers. These findings were correlated with trough TDM measurements at the time of toxicity presentation. Results TDM results from 378 patients (piperacillin = 223, meropenem = 94 and flucloxacillin = 61) were investigated. There was no difference in baseline patient characteristics across antibiotic groups. A statistically significant elevation in mean serum trough concentrations (Cmin) was found in patients diagnosed with neurotoxicity (piperacillin, P < 0.01; meropenem, P = 0.04; flucloxacillin, P = 0.01) and those who developed nephrotoxicity whilst being treated with piperacillin (P < 0.01) or meropenem (P < 0.01). Incidence of hepatotoxicity and C. difficile was not related to Cmin. Threshold concentrations for which there is 50% risk of developing a neurotoxicity event (piperacillin, Cmin >361.4 mg/L; meropenem, Cmin >64.2 mg/L; flucloxacillin, Cmin >125.1 mg/L) or nephrotoxicity (piperacillin, Cmin >452.65 mg/L; meropenem, Cmin >44.45 mg/L) varied across antibiotics. Conclusions Our data reveal an association between toxic concentrations for a number of β-lactam agents and neurotoxic/nephrotoxic effects. We have defined threshold concentrations above which these toxicities become more likely. Clinicians should balance concerns for therapeutic efficacy with potential toxicity when considering aggressive therapy.

Abstract
Background Guidelines from 2005 for treating suspected sepsis in low- and middle-income countries (LMIC) recommended hospitalisation and prophylactic intramuscular (IM) or intravenous (IV) ampicillin and gentamicin. In 2015, recommendations when referral to hospital is not possible suggest the administration of IM gentamicin and oral amoxicillin. In an era of increasing antimicrobial resistance, an updated review of the appropriate empirical therapy for treating sepsis (taking into account susceptibility patterns, cost and risk of adverse events) in neonates and children is necessary. Methods Systematic literature review and international guidelines were used to identify published evidence regarding the treatment of (suspected) sepsis. Results Five adequately designed and powered studies comparing antibiotic treatments in a low-risk community in neonates and young infants in LMIC were identified. These addressed potential simplifications of the current WHO treatment of reference, for infants for whom admission to inpatient care was not possible. Research is lacking regarding the treatment of suspected sepsis in neonates and children with hospital-acquired sepsis, despite rising antimicrobial resistance rates worldwide. Conclusions Current WHO guidelines supporting the use of gentamicin and penicillin for hospital-based patients or gentamicin (IM) and amoxicillin (oral) when referral to a hospital is not possible are in accordance with currently available evidence and other international guidelines, and there is no strong evidence to change this. The benefit of a cephalosporin alone or in combination as a second-line therapy in regions with known high rates of non-susceptibility is not well established. Further research into hospital-acquired sepsis in neonates and children is required.

Abstract
OBJECTIVES Aminoglycosides (AG) are a group of bactericidal antibiotics with nephrotoxic effects that are commonly used in the treatment of hospitialized children. We have examined previous AG treatment as a risk factor for acute kidney injury (AKI) during current AG treatment. STUDY DESIGN We performed a retrospective cohort study of children ranging in age from 1 month to 18 years who were treated with AG between October 2008 and April 2012 at Montreal's Children's Hospital. Children for whom no serum creatinine data (SCr) were available and those with baseline renal disease were excluded from the analysis. Main exposures were prior AG use (number and hours of prior treatments) and time since last AG treatment. The main outcome was AKI, defined on the basis of the Kidney Disease: Improving Global Outcomes guidelines. Logistic regression was used to examine exposure-outcome associations. RESULTS AG treatments episodes with Stage 1, 2, and 3 AKI, respectively, were associated with a median of 98 [interquartile range (IQR) 339], 231 (IQR 688), and 111 (IQR 505) h of prior AG treatment, respectively, versus non-AKI (median 0, IQR 54 h) (p < 0.0001). AKI episodes were associated with a mean (± standard deviation) of 1.5 ± 1.8 AG treatments in the previous 6 months, versus 0.9 ± 1.6 AG treatments for non-AKI. The number of AG-treatment days during the preceding 6 months [adjusted odds ratio (adjOR) 1.04, 95 % confidence interval (CI) 1.03-1.06; p < 0.001], younger age (adjOR 0.96, 95 % CI 0.93-0.99; p = 0.009), admission to hematology-oncology department (adjOR 3.88, 95 % CI 2.17-6.96; p < 0.001), and tobramycin use (adjOR 1.77, 95 % CI 1.04-3.02; p = 0.04) were independently associated with AKI. Episodes with Stage 1 and 2 AKI were associated with fewer days since last treatment compared to non-AKI treatment (p < 0.02 and p < 0.005, respectively; Mann-Whitney test). CONCLUSIONS Based on these results, prior AG treatment is a risk factor for AKI and should be considered when dosing and monitoring hospitalized children being treated with AG.

Abstract
RATIONALE Ecthyma gangrenosum (Eg) is a necrotic lesion that is mostly seen in immunocompromised patients. It reflects a severe sepsis, possibly caused by Pseudomonas aeruginosa (Pa). PATIENT CONCERNS A healthy 3-year-old girl admitted to the Pediatric Emergency Department presented a sepsis-associated purpura with neurological and respiratory distress. INTERVENTIONS An empiric antibiotherapy (anti-meningococcal) was prescribed. DIAGNOSES Forty-eight hours after admission, blood and wound cultures were positive for Pa. As a result, the decision was made to change the antibiotic therapy.Unfortunately, on day 3, the patient died. Exhaustive immunologic tests are presently being carried out. OUTCOMES Eg caused by Pa is uncommon in healthy children, and purpura sepsis is usually caused by Neisseria meningitides infection. LESSONS Eg should be recognized rapidly so that the appropriate treatment can be prescribed as quickly as possible.

Abstract
OBJECTIVES ICU-acquired bloodstream infection (ICUBSI) in Intensive Care unit (ICU) is still associated with a high mortality rate. The increase of antimicrobial drug resistance makes its treatment increasingly challenging. METHODS We analyzed 571 ICU-BSI occurring amongst 10,734 patients who were prospectively included in the Outcomerea Database and who stayed at least 4 days in ICU. The hazard ratio of death associated with ICU-BSI was estimated using a multivariate Cox model adjusted on case mix, patient severity and daily SOFA. RESULTS ICU-BSI was associated with increased mortality (HR, 1.40; 95% CI, 1.16-1.69; p = 0.0004). The relative increase in the risk of death was 130% (HR, 2.3; 95% CI, 1.8-3.0) when initial antimicrobial agents within a day of ICU-BSI onset were not adequate, versus only 20% (HR, 1.2; 95% CI, 0.9-1.5) when an adequate therapy was started within a day. The adjusted hazard ratio of death was significant overall, and even higher when the ICU-BSI source was pneumonia or unknown origin. When treated with appropriate antimicrobial agents, the death risk increase was similar for ICU-BSI due to multidrug resistant pathogens or susceptible ones. Interestingly, combination therapy with a fluoroquinolone was associated with more favorable outcome than monotherapy, whereas combination with aminoglycoside was associated with similar mortality than monotherapy. CONCLUSIONS ICU-BSI was associated with a 40% increase in the risk of 30-day mortality, particularly if the early antimicrobial therapy was not adequate. Adequacy of antimicrobial therapy, but not pathogen resistance pattern, impacted attributable mortality.

Aminoglycoside use in a pediatric hospital: there is room for improvement-a before/after study. Eur J Pediatr 2016; 175:659-65. [PMID: 26792290 DOI: 10.1007/s00431-016-2691-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/28/2015] [Revised: 11/12/2015] [Accepted: 01/08/2016] [Indexed: 10/22/2022]
Abstract
UNLABELLED Aminoglycoside prescriptions were rarely evaluated in children care facilities. Because of risk of toxicity, these narrow spectrum antibiotics are commonly misused. In this study, we evaluate aminoglycoside prescription and assess the impact of an information campaign on modalities of prescription and monitoring practices in a pediatric hospital. This prospective study, before/after diffusion of local recommendations, has been conducted over 6 months. All computerized prescriptions were analyzed. A semi-passive diffusion of local recommendations to prescribers allowed researchers to differentiate between a pre-intervention (P1) and post-intervention period (P2). Endpoints were the improvement of administered doses (mg/kg), modalities of administration, treatment duration, indications, and the presence of pharmacological monitoring. Three hundred and ten prescriptions were analyzed (P1 = 163, P2 = 147). Most common sites of infection treated were as follows: joint-bone (33 %), urinary tract (17 %) and intra-abdominal (15 %). Among all prescriptions, respectively, 12 and 13 % were avoidable. Short-duration treatment and single daily dosing seem to be widely achieved, but despite an improvement between the two periods, 45 % of prescribed doses in P2 were still below our recommendations (77 % in P1). CONCLUSION The semi-passive diffusion of recommendations has not improved significantly medical practices. Active diffusion with a regular monitoring could be useful to improve the use of aminoglycosides. WHAT IS KNOWN • Misuse of aminoglycosides has been frequently described and evaluated in adult hospitals. • This misuse could be explained by their nephrotoxicity and their low therapeutic index. What is New: • Through this study, conducted in a pediatric hospital, we highlighted that practitioners misunderstand the aminoglycoside pharmacokinetic and pharmacodynamic targets and 12.3 % of aminoglycoside prescriptions could be avoided. • Finally, we showed that a semi-passive diffusion of local recommendations is not enough to improve aminoglycoside prescriptions.

Abstract
BACKGROUND Bacteremia caused by members of the Enterobacteriaceae can be life threatening. Appropriate antimicrobial therapy is critical to reducing morbidity and mortality. METHODS This retrospective cohort study (2008-2011) was conducted in children and young adults (<21 years of age) hospitalized with Enterobacteriaceae bacteremia with clinical signs and symptoms of infection. We investigated whether combination empiric antimicrobial therapy was superior to monotherapy for treatment. Monotherapy was defined as empiric therapy with a β-lactam agent alone. Combination therapy was defined as coadministration of a β-lactam agent with an aminoglycoside agent for at least 48 hours before the susceptibility data were known. Outcome was measured as the response to therapy (defined as the time to negative blood culture) and was compared among patients administered monotherapy versus combination therapy. RESULTS Of 203 episodes of Enterobacteriaceae bacteremia, 78 (38%) were caused by Klebsiella spp, 73 (36%) were caused by Escherichia coli, and 52 (26%) were caused by Enterobacter spp. Of 203 episodes of bacteremia caused by 3 organisms of greatest interest, 101 (50%) were treated with combination therapy. Patients with cancer were more likely to receive combination therapy (38% vs. 16%; P < 0.001); patients with gastrointestinal disease and those receiving total parenteral nutrition were more likely to receive monotherapy (58% vs. 39%; P = 0.006 and 54% vs. 37%; P = 0.013, respectively). There was no difference in outcome in patients receiving monotherapy versus combination therapy (P = 0.86). CONCLUSION Combination therapy consisting of a β-lactam agent and an aminoglycoside agent was not superior to monotherapy with a β-lactam agent alone for managing Enterobacteriaceae bacteremia in children and young adults.

Abstract
BACKGROUND Uncertainty exists regarding the role of synergistic gentamicin for uncomplicated Enterococcus faecalis bacteremia in children. METHODS We conducted a retrospective, observational study comparing clinical outcomes of children with E. faecalis bacteremia without endocarditis receiving ampicillin monotherapy with those receiving ampicillin along with low-dose gentamicin therapy. To account for nonrandom assignment of combination therapy, propensity score weighting was combined with multivariable regression to estimate the effect of combination therapy on duration of bacteremia, bacteremic relapse, and acute kidney injury (AKI). RESULTS One hundred sixty-three (52%) patients received ampicillin with low-dose gentamicin, and 150 (48%) patients received ampicillin monotherapy. Incorporating propensity-score weighting with additional adjustment for source control measures, patients receiving combination therapy experienced bacterial clearance 10 hours faster than children receiving ampicillin monotherapy (adjusted mean difference 0.42; confidence interval (CI), .02 to .82; P = .04). Bacteremic relapse was similar between the two groups (17% vs 18%); adjusted hazards ratio (aHR) 1.12; 95% CI, .65 to 1.92. Children receiving low-dose gentamicin had approximately twice the risk of developing AKI compared to children not receiving this agent, adjusting for the receipt of additional nephrotoxins (aHR 1.94; 95% CI, 1.48-2.97). CONCLUSIONS Our study suggests that for children with uncomplicated E. faecalis bacteremia, the addition of low-dose gentamicin may decrease the time to bacterial clearance by 10 hours but without any impact on recurrent bacteremia. However, with this potential benefit comes the increased likelihood of AKI. Low-dose gentamicin for the treatment of uncomplicated enterococcal bacteremia may pose harm to children with limited benefit.

Abstract
Sepsis caused by multidrug-resistant microorganisms is one of the most serious infectious diseases of childhood and poses significant challenges for pediatricians involved in management of critically ill children. This review discusses the use of pharmacokinetic/dynamic principles (i.e., prolonged infusion of β-lactams and vancomycin, once-daily administration of aminoglycosides and rationale of therapeutic drug monitoring) when prescribing antibiotics to critically ill patients. The potential of 'old' agents (i.e., colistin, fosfomycin) and newly approved antibiotics is critically reviewed. The pros and cons of combination antibacterial therapy are discussed and finally suggestions for the treatment of sepsis caused by multidrug-resistant organisms are provided.

Abstract
BACKGROUND Empirical combination antibiotic regimens consisting of a β-lactam and an aminoglycoside are frequently employed in the pediatric population. Data to demonstrate the comparative benefit of empirical β-lactam combination therapy relative to monotherapy for culture-proven Gram-negative bacteremia are lacking in the pediatric population. METHODS We conducted a retrospective cohort study of children treated for Gram-negative bacteremia at The Johns Hopkins Hospital from 2004 through 2012. We compared the estimated odds of 10-day mortality and the relative duration of bacteremia for children receiving empirical combination therapy versus empirical monotherapy using 1:1 nearest-neighbor propensity-score matching without replacement, before performing regression analysis. RESULTS We identified 226 matched pairs of patients well balanced on baseline covariates. Ten-day mortality was similar between the groups (odds ratio, 0.84; 95% confidence interval [CI], 0.28 to 1.71). Use of empirical combination therapy was not associated with a decrease in the duration of bacteremia (-0.51 days; 95% CI, -2.22 to 1.48 days). There was no survival benefit when evaluating 10-day mortality for the severely ill (pediatric risk of mortality III score ≥15) or profoundly neutropenic patients (absolute neutrophil count ≤100 cells/mL) receiving combination therapy. However, a survival benefit was observed when empirical combination therapy was prescribed for children growing multidrug-resistant Gram-negative organisms from the bloodstream (odds ratio, 0.70; 95% CI, 0.51 to 0.84). CONCLUSIONS Although there appears to be no advantage to the routine addition of an aminoglycoside to a β-lactam as empirical therapy for children who have Gram-negative bacteremia, children who have risk factors for MDRGN organisms appear to benefit from this practice.
