Abstract
Blood culture, the gold-standard method for identifying pathogens in bloodstream infections, is time-consuming and demonstrates low sensitivity. These drawbacks are related to high mortality, especially among pediatric oncology patients presenting febrile neutropenia episodes. Here we describe two novel High-Resolution Melting assays designed for pathogen detection in bloodstream infections. The assays were initially evaluated using five sepsis-associated pathogens. Both assays demonstrated 100 % specificity, detected as low as 100 fg of bacterial DNA, and exhibited reproducibility. Clinical isolates from blood cultures were 100 % identified by both assays. Moreover, blind and direct identification of blood samples from pediatric cancer patients demonstrated sensitivities of 61.5 % and 69.2 % for "Primer Set 1" and "Primer Set 2", respectively. Our study highlights the potential of HRM-based assays as a rapid and efficient diagnostic approach for sepsis-related microorganisms. Further advancements could enhance their clinical utility for better management of febrile neutropenia episodes, especially in pediatric oncology patients.

Abstract
Background Neutropenic sepsis is a common complication of systemic anticancer treatment. There is variation in practice in timing of switch to oral antibiotics after commencement of empirical intravenous antibiotic therapy. Objectives To establish the clinical and cost effectiveness of early switch to oral antibiotics in patients with neutropenic sepsis at low risk of infective complications. Design A randomised, multicentre, open-label, allocation concealed, non-inferiority trial to establish the clinical and cost effectiveness of early oral switch in comparison to standard care. Setting Nineteen UK oncology centres. Participants Patients aged 16 years and over receiving systemic anticancer therapy with fever (≥ 38°C), or symptoms and signs of sepsis, and neutropenia (≤ 1.0 × 109/l) within 24 hours of randomisation, with a Multinational Association for Supportive Care in Cancer score of ≥ 21 and receiving intravenous piperacillin/tazobactam or meropenem for < 24 hours were eligible. Patients with acute leukaemia or stem cell transplant were excluded. Intervention Early switch to oral ciprofloxacin (750 mg twice daily) and co-amoxiclav (625 mg three times daily) within 12-24 hours of starting intravenous antibiotics to complete 5 days treatment in total. Control was standard care, that is, continuation of intravenous antibiotics for at least 48 hours with ongoing treatment at physician discretion. Main outcome measures Treatment failure, a composite measure assessed at day 14 based on the following criteria: fever persistence or recurrence within 72 hours of starting intravenous antibiotics; escalation from protocolised antibiotics; critical care support or death. Results The study was closed early due to under-recruitment with 129 patients recruited; hence, a definitive conclusion regarding non-inferiority cannot be made. Sixty-five patients were randomised to the early switch arm and 64 to the standard care arm with subsequent intention-to-treat and per-protocol analyses including 125 (intervention n = 61 and control n = 64) and 113 (intervention n = 53 and control n = 60) patients, respectively. In the intention-to-treat population the treatment failure rates were 14.1% in the control group and 24.6% in the intervention group, difference = 10.5% (95% confidence interval 0.11 to 0.22). In the per-protocol population the treatment failure rates were 13.3% and 17.7% in control and intervention groups, respectively; difference = 3.7% (95% confidence interval 0.04 to 0.148). Treatment failure predominantly consisted of persistence or recurrence of fever and/or physician-directed escalation from protocolised antibiotics with no critical care admissions or deaths. The median length of stay was shorter in the intervention group and adverse events reported were similar in both groups. Patients, particularly those with care-giving responsibilities, expressed a preference for early switch. However, differences in health-related quality of life and health resource use were small and not statistically significant. Conclusions Non-inferiority for early oral switch could not be proven due to trial under-recruitment. The findings suggest this may be an acceptable treatment strategy for some patients who can adhere to such a treatment regimen and would prefer a potentially reduced duration of hospitalisation while accepting increased risk of treatment failure resulting in re-admission. Further research should explore tools for patient stratification for low-risk de-escalation or ambulatory pathways including use of biomarkers and/or point-of-care rapid microbiological testing as an adjunct to clinical decision-making tools. This could include application to shorter-duration antimicrobial therapy in line with other antimicrobial stewardship studies. Trial registration This trial is registered as ISRCTN84288963.

Abstract
BACKGROUND Fever in neutropenia (FN) remains a serious complication of childhood cancer therapy. Clinical decision rules (CDRs) are recommended to help distinguish between children at high and low risk of severe infection. The aim of this analysis was to develop new CDRs for three different outcomes and to externally validate published CDRs. PROCEDURE Children undergoing chemotherapy for cancer were observed in a prospective multicenter study. CDRs predicting low from high risk infection regarding three outcomes (bacteremia, serious medical complications (SMC), safety relevant events (SRE)) were developed from multivariable regression models. Their predictive performance was assessed by internal cross-validation. Published CDRs suitable for validation were identified by literature search. Parameters of predictive performance were compared to assess reproducibility. RESULTS In 158 patients recruited between April 2016 and August 2018, 360 FN episodes were recorded, including 56 (16%) with bacteremia, 30 (8%) with SMC and 72 (20%) with SRE. The CDRs for bacteremia and SRE used four characteristics (type of malignancy, severely reduced general condition, leucocyte count <0.3 G/L, bone marrow involvement), the CDR for SMC two characteristics (severely reduced general condition and platelet count <50 G/L). Eleven published CDRs were analyzed. Six CDRs showed reproducibility, but only one in both sensitivity and specificity. CONCLUSIONS This analysis developed CDRs predicting bacteremia, SMC or SRE at presentation with FN. In addition, it identified six published CDRs that show some reproducibility. Validation of CDRs is fundamental to find the best balance between sensitivity and specificity, and will help to further improve management of FN.

Abstract
BACKGROUND Bacterial bloodstream infections are a major cause of morbidity and mortality in children with cancer and episodes of fever and neutropenia (FN). The aim of this study was to evaluate the clinical outcome in children with cancer with 2 or more microorganisms isolated from blood cultures during their episodes of FN. METHODS Between 2016 and 2021, children presenting with high-risk FN, admitted to any of the 6 participating hospitals in Santiago, Chile, were included in this study if they have positive blood cultures. We compared the clinical outcome of children with 2 or more microorganisms versus those with single agent isolation. RESULTS A total of 1074 episodes of high-risk FN were enrolled in the study period, of which 27% (298) had positive blood cultures and 3% (32) had 2 or more microorganisms isolated from blood cultures. The most frequent identified agents were Viridans group streptococci and Escherichia coli in 20%, followed by Coagulase negative staphylococci in 14%. Children with 2 or more microorganisms presented more days of fever (7 vs. 4 days, P = 0.02), needed longer courses of antimicrobial therapy (16 vs. 14 days, P = 0.04) and had higher mortality at day 30 (13% vs. 1%, P = 0.003). CONCLUSIONS Children with cancer and FN with 2 or more microorganisms isolated from blood cultures had a worse clinical outcome than children with single agent isolation.

Abstract
BACKGROUND Adolescents and young adults with cancer (AYA) are a complex group of patients. The development of fever and neutropenia (FN) is a potentially lethal complication of chemotherapy. Risk stratification of patients with FN has become increasingly valuable allowing for early intervention and to guide treatment type and duration appropriately. There are risk stratification guidelines that exist, but most are validated in young children with cancer (YCWC). AYA are frequently shown to have more numerous and severe side effects from chemotherapy. AIMS This study aimed to identify whether age contributes to the incidence and severity of FN. METHODS AND RESULTS Patients diagnosed with a malignancy in a 5-year period at our institution were included from ages 0-18 years. We reviewed details of their FN events, including duration of hospital admission, source (bacterial/fungal), PICU admission and duration, positive blood cultures and mortality. Adolescents with cancer (AWC) had a trend of being 1.56 times more likely to have FN events (CI 95% 0.936-2.622, p = 0.087). Assessment of the duration of PICU stay showed that AWC were 4.9 times more likely to have longer admissions (CI 95% 0.998-24.067, p = 0.050). There was no significant difference between the two groups in the rate of PICU admission, positive cultures, identification of a bacterial or fungal source, hospital admission duration or mortality from FN. CONCLUSION This study demonstrated a trend towards AWC being more likely to develop FN events. When such events occur in this group, the severity of them may be heightened as evidenced by longer duration of PICU admission.

Abstract
INTRODUCTION This guideline was written by a multidisciplinary committee with mandated members of the Dutch Society for Infectious Diseases, Dutch Society for Hematology, Dutch Society for Medical Oncology, Dutch Association of Hospital Pharmacists, Dutch Society for Medical Microbiology, and Dutch Society for Pediatrics. The guideline is written for adults and pediatric patients. METHOD The recommendations are based on the answers to nine questions formulated by the guideline committee. To provide evidence-based recommendations we used all relevant clinical guidelines published since 2010 as a source, supplemented with systematic searches and evaluation of the recent literature (2010-2020) and, where necessary, supplemented by expert-based advice. RESULTS For adults the guideline distinguishes between high- and standard-risk neutropenia based on expected duration of neutropenia (> 7 days versus ≤ 7 days). Where possible a distinction has been made between pediatric and adult patients. CONCLUSION This guideline was written to aid diagnosis and management of patients with febrile neutropenia due to chemotherapy in the Netherlands. The guideline provides recommendation for children and adults. Adults patient are subdivided as having a standard- or high-risk neutropenic episode based on estimated duration of neutropenia. The most important recommendations are as follows. In adults with high-risk neutropenia (duration of neutropenia > 7 days) and in children with neutropenia, ceftazidime, cefepime, and piperacillin-tazobactam are all first-choice options for empirical antibiotic therapy in case of fever. In adults with standard-risk neutropenia (duration of neutropenia ≤ 7 days) the MASCC score can be used to assess the individual risk of infectious complications. For patients with a low risk of infectious complications (high MASCC score) oral antibiotic therapy in an outpatient setting is recommended. For patients with a high risk of infectious complications (low MASCC score) antibiotic therapy per protocol sepsis of unknown origin is recommended.

Abstract
Febrile neutropenia is the most frequent complication in children treated with chemotherapy. Nevertheless, neutropenic children are a very heterogeneous group and invasive bacterial infections concern a minority of patients. Reducing antibiotics would bring many benefits. Yet, we can only explore this strategy if the safety of children is preserved. The main aims of this review were to study the safety and effectiveness of reducing antibiotic use in children with febrile neutropenia in terms of duration, route of administration (oral versus intravenous) and narrowing of antimicrobial spectrum. Cochrane Library, Pubmed and Embase were searched for relevant articles until February 2020. We have included all articles describing controlled trials written in French or in English. The risk of bias was assessed with ROB-2 (Cochrane Handbook for Systematic Reviews of Interventions Version 6.0. 2019, Chap. 8) or ROBINS-1 (Cochrane Handbook for Systematic Reviews of Interventions Version 6.0. 2019, Chap. 25). On 2351 articles, the systematic research retained 13 studies. Nine were used for a meta-analysis comparing oral versus intravenous treatment. We found no pediatric studies concerning de-escalation of empiric broad-spectrum antibiotics. No publication biases were found and almost all of the selected studies were at low risk or with some concern for bias. In comparing oral versus intravenous treatment and early cessation versus continuing antibiotics when no infection is proven, we found no difference in terms of safety (mortality and admission in intensive care unit) and efficacy (need of readmission/antibiotic modification/recurrence of fever). It seems safe and effective to provide oral treatment in low-risk febrile neutropenia and to stop antibiotics when no bacterial infection is proven. Spectrum reduction remains an important topic in pediatric research.Supplemental data for this article is available online at https://doi.org/10.1080/08880018.2022.2055245.

Abstract
Introduction Determining which febrile pediatric hematology/oncology (PHO) patients will decompensate from severe infection is a significant challenge. Serum lactate is a well-established marker of illness severity in general adult and pediatric populations, however its utility in PHO patients is unclear given that chemotherapy, organ dysfunction, and cancer itself can alter lactate metabolism. In this retrospective analysis, we studied the association of initial serum lactate in febrile immunosuppressed PHO patients with illness severity, defined by the incidence of clinical deterioration events (CDE) and invasive bacterial infection (IBI) within 48 hours. Methods Receiver operating characteristic (ROC) curves were reported using initial lactate within two hours of arrival as the sole predictor for CDE and IBI within 48 hours. Using a generalized estimating equations (GEE) approach, the association of lactate with CDE and IBI within 48 hours was tested in univariate and multivariable analyses including covariates based on Quasi-likelihood under Independence Model Criterion (QIC). Additionally, the association of lactate with secondary outcomes (i.e., hospital length of stay (LOS), intensive care unit (PICU) admission, PICU LOS, non-invasive infection) was assessed. Results Among 897 encounters, 48 encounters had ≥1 CDE (5%), and 96 had ≥1 IBI (11%) within 48 hours. Elevated lactate was associated with increased CDE in univariate (OR 1.77, 95%CI: 1.48-2.12, p<0.001) and multivariable (OR 1.82, 95%CI: 1.43-2.32, p<0.001) analyses, longer hospitalization (OR 1.15, 95%CI: 1.07-1.24, p<0.001), increased PICU admission (OR 1.68, 95%CI: 1.41-2.0, p<0.001), and longer PICU LOS (OR 1.21, 95%CI: 1.04-1.4, p=0.01). Elevated lactate was associated with increased IBI in univariate (OR 1.40, 95%CI: 1.16-1.69, p<0.001) and multivariable (OR 1.49, 95%CI: 1.23-1.79, p<0.001) analyses. Lactate level was not significantly associated with increased odds of non-invasive infection (p=0.09). The QIC of the model was superior with lactate included for both CDE (305 vs. 325) and IBI (563 vs. 579). Conclusions These data demonstrated an independent association of elevated initial lactate level and increased illness severity in febrile PHO patients, suggesting that serum lactate could be incorporated into future risk stratification strategies for this population.

Abstract
BACKGROUND Children receiving cytotoxic therapy for cancer have increased risk of infection due to drug-induced neutropenia and are therefore treated empirically for bacteremia when febrile or ill-appearing. However, viral infections, which are not frequently life-threatening, are the most common etiology of febrile episodes and there has been increased effort to differentiate patients who may have a higher risk for adverse outcomes. CASE We performed a retrospective chart review of pediatric oncology patients diagnosed with COVID-19 between December 20, 2021 and February 22, 2022 during the Omicron (B.1.1.529) surge at The Children's Hospital at Montefiore, a tertiary care center in the Bronx. CONCLUSION We found that no patients in our cohort developed respiratory distress, bacteremia, or serious illness after COVID-19 infection during the Omicron surge. Future studies will aid in understanding the relationship between community-acquired infections and bacteremia, and this knowledge can then be applied to develop optimal infection prevention clinical care guidelines.

Abstract
BACKGROUND Febrile neutropenia (FN) is an early indicator of infection in oncology patients post-chemotherapy. We aimed to determine clinical predictors of septic shock and/or bacteremia in pediatric cancer patients experiencing FN and to create a model that classifies patients as low-risk for these outcomes. METHODS This is a retrospective analysis with clinical data of a cohort of pediatric oncology patients admitted during July 2015 to September 2017 with FN. One FN episode per patient was randomly selected. Statistical analyses include distribution analysis, hypothesis testing, and multivariate logistic regression to determine clinical feature association with outcomes. RESULTS A total of 865 episodes of FN occurred in 429 subjects. In the 404 sampled episodes that were analyzed, 20.8% experienced outcomes of septic shock and/or bacteremia. Gram-negative bacteria count for 70% of bacteremias. Features with statistically significant influence in predicting these outcomes were hematological malignancy (P < .001), cancer relapse (P = .011), platelet count (P = .004), and age (P = .023). The multivariate logistic regression model achieves AUROC = 0.66 (95% CI 0.56-0.76). The optimal classification threshold achieves sensitivity = 0.96, specificity = 0.33, PPV = 0.40, and NPV = 0.95. CONCLUSIONS This model, based on simple clinical variables, can be used to identify patients at low-risk of septic shock and/or bacteremia. The model's NPV of 95% satisfies the priority to avoid discharging patients at high-risk for adverse infection outcomes. The model will require further validation on a prospective population.

A Dynamic Approach for Early Risk Prediction of Gram-Negative Bloodstream Infection and Systemic Inflammatory Response Syndrome in Febrile Pediatric Hemato-Oncology Patients. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9060833. [PMID: 35740770 PMCID: PMC9222073 DOI: 10.3390/children9060833] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Revised: 05/31/2022] [Accepted: 06/01/2022] [Indexed: 11/17/2022]
Abstract
Background: The aim of this study was to evaluate the usefulness of C-Reactive Protein (CRP), Procalcitonin (PCT), and Interleukine 6 (IL6) biomarkers in predicting the existence of high-risk episodes (HRE) during the first 24 h of fever in pediatric cancer patients. HRE were defined as the presence of Gram-negative bloodstream infections or Systemic Inflammatory Response Syndrome. Methods: The study included 103 consecutive fever episodes in 44 hemato-oncological pediatric patients, from whom samples for biomarkers were taken upon initial evaluation (CRP-1, PCT-1 and IL6-1) and then between 12 and 24 h afterward (CRP-2, PCT-2 and IL6-2). Results: An IL6-1 value higher than 164 pg/mL showed an area under the curve (AUC) of 0.890 (0.791−0.989) and OR of 48.68 (7.92−951.42, p < 0.001) to detect HRE in multivariate analysis. A PCT-1 higher than 0.32 ng/mL showed an AUC of 0.805 (0.700−0.910) and OR of 4.55 (0.90−27.84, p = 0.076). A PCT-2 higher than 0.94 ng/mL showed an AUC of 0.836 (0.725−0.947) and OR of 13.01 (1.82−149.13, p = 0.018), and an increase in CRP between the first and second sample (CRP-2vs1) higher than 291% also showed an AUC of 0.785 (0.655−0.915) and OR of 31.09 (4.87−355.33, p = 0.001). Conclusions: IL6-1, PCT-2, and CRP-2vs1 showed a strong and independent correlation with HREs in pediatric cancer patients. CRP variations over the first 24 h provide an improvement in predictive models that are especially useful if IL-6 and PCT are not available.

Abstract
Febrile neutropenia (FN) is a common condition in children receiving chemotherapy. Our goal in this study was to develop a model for predicting blood stream infection (BSI) and transfer to intensive care (TIC) at time of presentation in pediatric cancer patients with FN. We conducted an observational cohort analysis of pediatric and adolescent cancer patients younger than 24 years admitted for fever and chemotherapy-induced neutropenia over a 7-year period. We excluded stem cell transplant recipients who developed FN after transplant and febrile non-neutropenic episodes. The primary outcome was onset of BSI, as determined by positive blood culture within 7 days of onset of FN. The secondary outcome was transfer to intensive care (TIC) within 14 days of FN onset. Predictor variables include demographics, clinical, and laboratory measures on initial presentation for FN. Data were divided into independent derivation (2009-2014) and prospective validation (2015-2016) cohorts. Prediction models were built for both outcomes using logistic regression and random forest and compared with Hakim model. Performance was assessed using area under the receiver operating characteristic curve (AUC) metrics. A total of 505 FN episodes (FNEs) were identified in 230 patients. BSI was diagnosed in 106 (21%) and TIC occurred in 56 (10.6%) episodes. The most common oncologic diagnosis with FN was acute lymphoblastic leukemia (ALL), and the highest rate of BSI was in patients with AML. Patients who had BSI had higher maximum temperature, higher rates of prior BSI and higher incidence of hypotension at time of presentation compared with patients who did not have BSI. FN patients who were transferred to the intensive care (TIC) had higher temperature and higher incidence of hypotension at presentation compared to FN patients who didn't have TIC. We compared 3 models: (1) random forest (2) logistic regression and (3) Hakim model. The areas under the curve for BSI prediction were (0.79, 0.65, and 0.64, P < 0.05) for models 1, 2, and 3, respectively. And for TIC prediction were (0.88, 0.76, and 0.65, P < 0.05) respectively. The random forest model demonstrated higher accuracy in predicting BSI and TIC and showed a negative predictive value (NPV) of 0.91 and 0.97 for BSI and TIC respectively at the best cutoff point as determined by Youden's Index. Likelihood ratios (LRs) (post-test probability) for RF model have potential utility of identifying low risk for BSI and TIC (0.24 and 0.12) and high-risk patients (3.5 and 6.8) respectively. Our prediction model has a very good diagnostic performance in clinical practices for both BSI and TIC in FN patients at the time of presentation. The model can be used to identify a group of individuals at low risk for BSI who may benefit from early discharge and reduced length of stay, also it can identify FN patients at high risk of complications who might benefit from more intensive therapies at presentation.

Predictive Factors for Gram-negative Versus Gram-positive Bloodstream Infections in Children With Cancer. J Pediatr Hematol Oncol 2022; 44:e368-e373. [PMID: 34310469 DOI: 10.1097/mph.0000000000002253] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2021] [Accepted: 05/23/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND Identifying potential predictive factors for the type of bacteremia (Gram-negative vs. Gram-positive) in children with cancer would be crucial for the timely selection of the appropriate empiric antibiotic treatment. MATERIALS AND METHODS Demographic, clinical, and laboratory characteristics of children with cancer and a bacterial bloodstream infection (BSI) (February 1, 2011 to February 28, 2018) in a tertiary pediatric oncology department were retrospectively examined and were correlated with the type of isolated bacteria. RESULTS Among 224 monomicrobial bacterial BSI episodes, Gram-negative and Gram-positive bacteria were isolated in 110 and 114 episodes, respectively. Gram-negative bacteria were isolated significantly more frequently in girls (Gram-negative/Gram-positive ratio 1.7:1) versus boys (Gram-negative/Gram-positive ratio 0.72:1), P=0.002, in patients with previous BSI episodes (1.4:1) versus those without (0.8:1), P=0.042, and in children with hematologic malignancy (1.3:1) versus those who suffered from solid tumors (0.52:1), P=0.003. Gram-negative BSI episodes were more frequently correlated with a lower count of leukocytes, P=0.009, neutrophils, P=0.009 and platelets, P=0.002, but with significantly higher C-reactive protein (CRP) levels, P=0.049. Female sex, hematologic malignancy, and higher CRP levels remained independent risk factors for Gram-negative BSI in the multivariate analysis. Among neutropenic patients, boys with solid tumors and a recent central venous catheter placement appear to be at increased risk for Gram-positive BSI in the multivariate analysis. CONCLUSIONS Although Gram-negative and Gram-positive BSIs are close to balance in children with cancer, Gram-negative bacteria are more likely to be isolated in girls, children with hematologic malignancies and those with higher CRP level at admission. In contrast, neutropenic boys with solid tumors and a recently placed central venous catheter may be at increased risk for Gram-positive BSI indicating probably the need for initially adding antibiotics targeting Gram-positive bacteria.

Abstract
OBJECTIVE Although bacteremia in pediatric oncology patients with febrile neutropenia (FN) is not uncommon, sepsis and mortality are rare. Because of the lack of clinically meaningful decision tools to identify high-risk patients with bacteremia, time to antibiotic administration (TTA) is increasingly considered an important quality and safety measure in the emergency department. Because little evidence exists suggesting that this benchmark is beneficial, we sought to determine whether TTA of 60 minutes or less is associated with improved outcomes. METHODS We retrospectively reviewed patients presenting to a pediatric emergency department with FN from November 2013 to June 2016. Clinical outcomes including mortality, pediatric intensive care unit admission, imaging, fluid resuscitation of 40 mL/kg or greater in the first 24 hours, and length of stay were compared between TTA of 60 minutes or less and more than 60 minutes. RESULTS One hundred seventy-nine episodes of FN were analyzed. The median TTA was 76 minutes (interquartile range, 58-105). The incidence of bacteremia was higher in patients with TTA of more than 60 minutes (12% vs 2%, P = 0.04), but without impact on mortality, pediatric intensive care unit admission, fluid resuscitation, or median length of stay. The median TTA was not different for those who were and were not bacteremic (91 vs 73 minutes, P = 0.11). CONCLUSIONS Time to antibiotic administration of more than 60 minutes did not increase mortality in pediatric oncology patients with FN. Our study adds to the existing literature that TTA of 60 minutes or less does not seem to improve outcomes in pediatric FN. Further larger studies are required to confirm these findings and determine which features predispose pediatric FN patients to morbidity and mortality.

Abstract
Febrile neutropenia (FN) is a common complication of chemotherapy in oncological children and one of the most important causes of morbidity and mortality in these patients. The early detection of a bacteremia and the rapid therapeutic intervention are crucial to improve the outcome. We analyzed the literature in order to clarify the epidemiology of FN in children undergoing chemotherapy, the specific factors associated with a negative outcome, the most common etiology, and the value of biological markers as a tool to make an early diagnosis or to monitor the evolution of the infection. Several studies have tried to identify specific factors that could help the clinician in the detection of an infection and in its microbiological identification. However, due to the heterogenicity of the available studies, sufficient evidence is lacking to establish the role of these risk factors in clinical practice and future research on this topic appear mandatory. Determinations of risk factors, etiology, and markers of febrile episodes in these patients are complicated by the characteristics of the underlying illness and the effects of treatments received. Although some studies have tried to develop an evidence-based guideline for the empiric management of FN in pediatrics, validated predictive scores and algorithms are still lacking and urgently needed.

Abstract
INTRODUCTION Febrile neutropenia (FN) is a serious complication of cancer chemotherapy. The present study aimed to identify risk factors for documented infection in pediatric patients with FN and cancer. METHODS This prospective cohort study included patients under 18 years from 2016 to 2018. Infection was defined according to the Centers for Disease Control and Prevention criteria. RESULTS A total of 172 febrile neutropenic episodes were evaluated. From univariate analysis, the risk factors were: female gender; monocyte count < 100 cell/mm³, platelets < 50,000, C-reactive protein (CRP) > 90 mg/dl and hemoglobin < 7mg/dl at the onset of an episode; two or more episodes of FN, and; fever onset; positive blood culture at the fever onset. Independent risk factors according to the multivariate analysis were: CRP at the onset of a febrile episode > 90mg/dl, fever onset and first blood culture with a positive result. The lowest probability of infection was related to first episode and to platelets > 50,000 at the onset of fever. CONCLUSION A CRP > 90 at the onset of a febrile episode, platelets < 50,000, second episode or more, first fever episode during hospitalization and positive first blood culture were found to be associated with a higher risk of infection and they could be useful for the establishment of risk scores for infection in neutropenic children.

Abstract
OBJECTIVE Febrile neutropenia (FN) represents a life-threatening complication in hematological malignancies. We aimed to analyze the utility of soluble vascular cell adhesion molecule 1 (sVCAM-1), intercellular adhesion molecule 1 (sICAM-1), vascular endothelial growth factor (VEGF) levels compared with C-reactive protein (CRP) and procalcitonin (PCT) during febrile neutropenia episodes of pediatric patients with leukemia. METHODS Two plasma samples, on day 0 (initial of episode) and day 3 (48-72 h after episode), for VCAM-1, ICAM-1 and VEGF, CRP and PCT were prospectively collected concomitantly during each febrile neutropenic episode between December 2016 and December 2017. The primary outcome was bacteremia and the secondary outcome was intensive care unit (ICU) admission. RESULTS Twenty-two (28.6%) acute lymphoblastic lymphoma (ALL), seventeen (22.1%) acute myeloblastic lymphoma (AML) patients and thirty-eight (49.3%) control patients with no known underlying disease or fever were included in this study. Of the 39 patients; 16 (41%) had bacteremia. Mean serum sVCAM1 and sICAM1 levels were significantly higher in control group, compared to FN patients (p < 0.001). Mean serum sVCAM2 level was significantly higher in FN patients with bacteremia compared to FN patients without bacteremia (144.97 ± 70.35 pg/mL vs 85.45 ± 53.76 pg/mL, p = 0.022). Mean sVCAM1 and 2 levels were higher in FN patients with ICU admission. In this study, we found that sVCAM-1 and VEGF, when combined to CRP and PCT, could predict gram-negative bacteremia in FN episodes of pediatric hematological malignancy. CONCLUSION Serum endothelial adhesion molecules, excluding sVCAM-1, cannot predict bacteremia and ICU admission alone in FN patients; but may be associated with clinical outcome when used with PCT and CRP.

Abstract
The management of febrile neutropenia (FN) in pediatrics is evolving. Our objective was to describe current practices for the care of patients with FN in pediatric oncology centers in Latin America and identify areas for practice improvement. We used an online survey to enroll eligible healthcare providers who treat children with cancer in Latin America. The survey addressed respondents’ characteristics, the environment of care, and FN care practices, including risk assessment, criteria for hospitalization, initial management of FN, evaluation, antibiotic administration, and discharge. From 220 surveys sent, we received 109 responses and selected 108 from 19 countries for analysis. Most (94%) respondents were working in specialized oncology centers, oncology units within a pediatric or general care hospital. The cohort included oncologists (42%) and infectious diseases physicians (30%). Most (67%) respondents had available guidelines; they used a risk-stratification scoring system (73%) for severe infection; and their guidelines had locally adapted risk stratification (34%) or published risk stratification (51%). The respondents used diverse FN definitions and concepts, including fever definitions, temperature-obtaining methods, neutropenia values for assigning risk, empiric antimicrobials administration, and length of hospitalization. Overall, we detected common practices aligning with standard published recommendations, as well as care variability. These findings can guide further evaluations of care resources and practices to prioritize interventions, and professional networks can be used for FN discussions and consensus in Latin America.

Abstract
Objectives Febrile neutropenia (FN) causes treatment disruption and unplanned hospitalization in children with cancer. Serum biomarkers are infrequently used to stratify these patients into high or low risk for serious infection. This study investigated plasma abundance of cytokines in children with FN and their ability to predict bacteraemia. Methods Thirty-three plasma cytokines, C-reactive protein (CRP) and procalcitonin (PCT) were measured using ELISA assays in samples taken at FN presentation (n = 79) and within 8–24 h (Day 2; n = 31). Optimal thresholds for prediction of bacteraemia were identified and the predictive ability of biomarkers in addition to routinely available clinical variables was assessed. Results The median age of included FN episodes was 6.0 years and eight (10%) had a bacteraemia. On presentation, elevated PCT, IL-10 and Mip1-beta were significantly associated with bacteraemia, while CRP, IL-6 and IL-8 were not. The combination of PCT (≥0.425 ng/ml) and IL-10 (≥4.37 pg/ml) had a sensitivity of 100% (95% CI 68.8–100%) and specificity of 89% (95% CI 80.0–95.0%) for prediction of bacteraemia, correctly identifying all eight bacteraemia episodes and classifying 16 FN episodes as high-risk. There was limited additive benefit of incorporating clinical variables to this model. On Day 2, there was an 11-fold increase in PCT in episodes with a bacteraemia which was significantly higher than that observed in the non-bacteraemia episodes. Conclusion Elevated PCT and IL-10 accurately identified all bacteraemia episodes in our FN cohort and may enhance the early risk stratification process in this population. Prospective validation and implementation is required to determine the impact on health service utilisation.

Abstract
Introduction Rapid time to antibiotics (TTA) for pediatric patients with fever and neutropenia in an emergency department decreases in-hospital mortality. Additionally, national guidelines recommend outpatient antibiotic management strategies for low-risk fever and neutropenia (LRFN). This study had two specific aims: (1) improve the percent of patients with suspected fever and neutropenia who receive antibiotics within 60 minutes of arrival from 55% to 90%, and (2) develop and operationalize a process for outpatient management of LRFN patients by October 2018. Methods Using Lean methodologies, we implemented Plan-Do-Check-Act cycles focused on guideline development, electronic medical record reminders, order-set development, and a LRFN pathway as root causes for improvements. We used statistical process control charts to assess results. Results The project conducted from July 2016 to October 2018 showed special cause improvement in December 2016 on a G-chart. Monthly Xbar-chart showed improvement in average TTA from 68.5 minutes to 42.5 minutes. A P-chart showed improvement in patients receiving antibiotics within 60 minutes, from 55% to 86.4%. A LRFN guideline and workflow was developed and implemented in October 2017. Conclusions Implementation of guidelines, electronic medical record reminders, and order sets are useful tools to improve TTA for suspected fever and neutropenia. Utilizing more sensitive statistical process control charts early in projects with fewer patients can help recognize and guide process improvement. The development of workflows for outpatient management of LRFN may be possible, though it requires further study.

Early Discontinuation versus Continuation of Antimicrobial Therapy in Low Risk Pediatric Cancer Patients with Febrile Neutropenia, Before Recovery of Counts: A Randomized Controlled Trial (DALFEN Study). Indian J Pediatr 2021; 88:240-245.

Abstract
OBJECTIVE To determine if early discontinuation of antimicrobials in pediatric patients with low risk febrile neutropenia is as effective as continuing therapy before recovery of counts, in an outpatient setting. METHODS In an open label, non-inferiority, randomized controlled phase 3 trial at a tertiary cancer center, patients aged 3-18 y, with low risk febrile neutropenia were started on empirical intra-venous antibiotics in an outpatient setting. Randomization was done when the patients became afebrile for at least 24 h; standard arm consisted of oral antibiotics, while antibiotics were stopped in the experimental arm. Enrolled patients were followed for re-appearance of fever and rate of re-admission, until ANC ≥ 500. A pilot feasibility randomized study with similar design preceded this trial. RESULTS From Jan 2017-Dec 2018, 75 patients were randomized: 38 to stoppage arm while 37 patients received oral antibiotics. Baseline characteristics were equally matched. Success rates were 94.6% in the continuation arm vs. 94.7% in the stoppage arm; absolute risk difference was 0.1% (95% CI: -10.0% to +10.3%), thus suggesting that the experimental arm is non-inferior to the standard arm. There was no re-admission on failure in any arm. CONCLUSIONS Antimicrobial therapy in low risk afebrile neutropenic patients can be stopped early. This approach can lead to significant cost and resource benefits.

Abstract
In low-risk febrile neutropenia (FN) patients, outpatient management is now an accepted treatment, but there is a scarcity of data on high-risk patients. The aim of our study was to describe the outcome of FN treated primarily in an outpatient setting on the basis of the severity of illness at presentation, irrespective of the intensity of chemotherapy, and absolute neutrophil count. In this prospective study, not severely ill (NSI) patients were treated with empiric antibiotics at the daycare center (outpatient) and were admitted subsequently if there was persistent fever or any complication arose. Severely ill (SI) children were admitted to the hospital upfront. A total of 118 FN episodes among children with cancer on chemotherapy 18 years of age and younger were studied. Among NSI patients managed as outpatients (n=103), 89 patients (86%) recovered with outpatient treatment, and 14 patients required hospitalization after the median duration of 5 days (interquartile range: 4 to 6 d) of antibiotic therapy. The main indication for hospital admission in the SI group was hypotension (n=5), and in the NSI group, it was persistent fever (n=11). Overall, 5% of patients (6/118) died, and 2 of these were in the NSI group. The results of this study suggest that carefully selected NSI patients could be successfully treated at outpatient management in resource-poor settings and subsequent admission if warranted.

Abstract
Febrile neutropenia in pediatric oncology patients may lead to severe infection, with adverse events including septic shock or death. The aim of the study was to investigate the prevalence of severe adverse outcomes and to determine the associated risk factors. This is a retrospective cohort study of pediatric oncology patients with febrile neutropenia from October 2013 to September 2017 at Thammasat University Hospital, Thailand. Clinical assessment and time-to-event of severe outcomes were analyzed. There were 95 febrile neutropenic episodes; severe adverse outcomes were documented in 11 (11.5%), with no infection-associated mortalities. Those with severe outcomes were older, received prophylactic granulocyte-colony stimulating factor (G-CSF), and had documented infection, lower initial ANC, and central venous catheter insertion. The proportional hazard regression model revealed age ≥ 10 years (hazard ratio [HR], 5.96; p = 0.005), prophylactic G-CSF (HR, 4.52; p = 0.028), and microbiologically documented infections (HR, 12.53; p = 0.017) independently predicted severe adverse outcomes. Although severe adverse outcomes occurred in only 11.5% of our febrile neutropenic episodes, we identified a few risk factors that may help predict those at highest risk.

Abstract
BACKGROUND Infectious Diseases Society of America guidelines defines febrile neutropenia (FN) patients as high risk, if they have an absolute neutrophil count (ANC) ≤100 cells/µL anticipated to last >7 days. However, data evaluating the clinical significance of the depth and duration of neutropenia are limited. METHODS We conducted a retrospective cohort study of pediatric oncology patients presenting with FN to examine whether the effects of the depth and duration of neutropenia prior to presentation were predictive of blood stream infection (BSI), invasive fungal disease (IFD), pediatric intensive care unit (PICU) admission or length of stay. RESULTS A total of 585 FN episodes (FNEs) were identified in 265 patients. ANC at the time of presentation was <100 in 411 (70%), 100-500 in 119 (20%), and >500 cells/μL with subsequent decline to <500 cells/μL in the next 48 hours in 55 (10%) of FNEs. In the group with ANC > 500 with subsequent decline in 48 hours, rates of IFD and BSI were higher when compared with ANC < 100 cells/μL [odds ratio (OR) = 5.9, 95% confidence interval (CI): 0.7-29.6] and (OR = 2.35, 95% CI: 01.02-5.4), and patients in this group were more likely to be admitted to the PICU (OR= 5.1, 95% CI: 1.134-19.46). No difference in outcomes was identified when the groups of ANC < 100 and ANC of 100-500 cells/μL were compared. Neutropenia >7 days prior to FNE was an independent risk factor for BSI (OR = 2.88, 95% CI: 1.55-5.35 and increased length of stay. CONCLUSIONS Clinicians should not be reassured when patients present with FN and initial ANC >500 cells/mL after recent chemotherapy if continued decline is expected as patients in this group are at high risk of IFD, BSI and PICU admission.

Abstract
BACKGROUND Numerous paediatric febrile neutropenia (FN) clinical decision rules (CDRs) have been derived. Validation studies show reduced performance in external settings. We evaluated the association between variables common across published FN CDRs and bacterial infection and recalibrated existing CDRs using these data. METHODS Prospective data from the Australian-PICNICC study which enrolled 858 FN episodes in children with cancer were used. Variables shown to be significant predictors of infection or adverse outcome in >1 CDR were analysed using multivariable logistic regression. Recalibration included re-evaluation of beta-coefficients (logistic model) or recursive-partition analysis (tree-based models). FINDINGS Twenty-five unique variables were identified across 17 FN CDRs. Fourteen were included in >1 CDR and 10 were analysed in our dataset. On univariate analysis, location, temperature, hypotension, rigors, severely unwell and decreasing platelets, white cell count, neutrophil count and monocyte count were significantly associated with bacterial infection. On multivariable analysis, decreasing platelets, increasing temperature and the appearance of being clinically unwell remained significantly associated. Five rules were recalibrated. Across all rules, recalibration increased the AUC-ROC and low-risk yield as compared to non-recalibrated data. For the SPOG-adverse event CDR, recalibration also increased sensitivity and specificity and external validation showed reproducibility. INTERPRETATION Degree of marrow suppression (low platelets), features of inflammation (temperature) and clinical judgement (severely unwell) have been consistently shown to predict infection in children with FN. Recalibration of existing CDRs is a novel way to improve diagnostic performance of CDRs and maintain relevance over time. FUNDING National Health and Medical Research Council Grant (APP1104527).

Abstract
BACKGROUND It has been suggested that low-risk febrile neutropenia (FN) episodes can be treated in a step-down manner in the outpatient setting. This recommendation has been limited to implementation in middle-income countries due to concerns about infrastructure and lack of trained personnel. We aimed to determine whether early step-down to oral antimicrobial outpatient treatment is not inferior in safety and efficacy to inpatient intravenous treatment in children with low-risk FN. PROCEDURE A noninferiority randomized controlled clinical trial was conducted in three hospitals in Mexico City. Low-risk FN was identified in children younger than 18 years. After 48 to 72 hours of intravenous treatment, children were randomly allocated to receive outpatient oral treatment (experimental arm, cefixime) or to continue inpatient treatment (standard of care, cefepime). Daily monitoring was performed until neutropenia resolution. The presence of any unfavorable clinical outcome was the endpoint of interest. We performed a noninferiority test for comparison of proportions. RESULTS We identified 1237 FN episodes; 117 cases were randomized: 60 to the outpatient group and 57 for continued inpatient treatment. Of the FN episodes, 100% in the outpatient group and 93% in the inpatient group had a favorable outcome (P < 0.001). The mean duration of antibiotics was 4.1 days (SD 2.5; 95% CI, 3.4-4.8 days) in the outpatient group and 4.4 days (SD 2.5; 95% CI, 3.7-5.0 days) in the inpatient group (P = 0.70). CONCLUSIONS In our population, step-down oral outpatient treatment of low-risk FN was as safe and effective as inpatient intravenous treatment. Clinical Trials Identifier: NCT04000711.

Abstract
Background: Infectious complications (IC) caused by bacterial strains often impede anticancer therapy. The study aimed to retrospectively analyze bacterial IC that could help predict the risk and optimize the empirical treatment for bacterial infections in pediatric cancer patients. Patients and Methods: Over a 72-month period, all-in 5,599 children with cancer: 2,441 patients with hematological malignancy (HM including acute leukemias, Hodgkin and non-Hodgkin lymphomas [NHLs], and Langerhans cell histiocytosis) and 3,158 with solid tumors (STs including central nervous system tumors, neuroblastoma, Wilms' tumor, soft tissue sarcoma, germ cell tumors, Ewing sarcoma, osteosarcoma, hepatoblastoma, and others) were enrolled into the study. Episodes of bacterial infectious complications (EBICs) confirmed by microbiological findings were reported by each hospital and analyzed centrally. Results: At least 1 EBIC was diagnosed in 2,155 (36.8%) children (1,281 [59.4%] with HM and 874 [40.6%] with ST; p < 0.001). All-in 4,860 EBICs were diagnosed including 62.2% episodes in children with HM and 37.8% in children with ST (p < 0.001). Having analyzed the source of infections, blood stream infections predominated, apart from NHL patients in whom the most common type was gut infections. The profile of bacteria strains was different in HM and ST groups (p < 0.001). However, in both groups the most common Gram-negative pathogen was Enterobacteriaceae, with the rate being higher in the HM group. Among Gram-negative strains low susceptibility to ceftazidime, whereas among Enterococcus spp. low susceptibility to vancomycin was noticed. The rate of multidrug-resistant (MDR) pathogens was high, especially for Gram negatives (47.7% vs. 23.9%; p < 0.001). The survival after infections was comparable for HM and ST patients (p = 0.215). Conclusions: The risk of bacterial IC in HM patients was higher than in the ST group. The high rate of MDR strains was detected in pediatric cancer patients, especially in those with HM.

Risk stratification in children with cancer and febrile neutropenia: A national, prospective, multicentre validation of nine clinical decision rules. EClinicalMedicine 2020; 18:100220. [PMID: 31993576 PMCID: PMC6978200 DOI: 10.1016/j.eclinm.2019.11.013] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2019] [Revised: 11/12/2019] [Accepted: 11/18/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Reduced intensity treatment of low-risk febrile neutropenia (FN) in children with cancer is safe and improves quality of life. Identifying children with low-risk FN using a validated risk stratification strategy is recommended. This study prospectively validated nine FN clinical decision rules (CDRs) designed to predict infection or adverse outcome. METHODS Data were collected on consecutive FN episodes in this multicentre, prospective validation study. The reproducibility and discriminatory ability of each CDR in the validation cohort was compared to the derivation dataset and details of missed outcomes were reported. FINDINGS There were 858 FN episodes in 462 patients from eight hospitals included. Bacteraemia occurred in 111 (12·9%) and a non-bacteraemia microbiological documented infection in 185 (21·6%). Eight CDRs exhibited reproducibility and sensitivity ranged from 64% to 96%. Rules that had >85% sensitivity in predicting outcomes classified few patients (<20%) as low risk. For three CDRs predicting a composite outcome of any bacterial or viral infection, the sensitivity and discriminatory ability improved for prediction of bacterial infection alone. Across all CDRs designed to be implemented at FN presentation, the sensitivity improved at day 2 assessment. INTERPRETATION While reproducibility was observed in eight out of the nine CDRs, no rule perfectly differentiated between children with FN at high or low risk of infection. This is in keeping with other validation studies and highlights the need for additional safeguards against missed infections or adverse outcomes before implementation can be considered.

Efficacy of pre-emptive versus empirical antifungal therapy in children with cancer and high-risk febrile neutropenia: a randomized clinical trial. J Antimicrob Chemother 2019; 73:2860-2866. [PMID: 30010931 DOI: 10.1093/jac/dky244] [Citation(s) in RCA: 35] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2018] [Accepted: 05/24/2018] [Indexed: 02/07/2023] Open
Abstract
Objectives To compare the efficacy of pre-emptive versus empirical antifungal therapy in children with cancer, fever and neutropenia. Methods This was a prospective, multicentre, randomized clinical trial. Children presenting with persistent high-risk febrile neutropenia at five hospitals in Santiago, Chile, were randomized to empirical or pre-emptive antifungal therapy. The pre-emptive group received antifungal therapy only if the persistent high-risk febrile neutropenia was accompanied by clinical, laboratory, imaging or microbiological pre-defined criteria. The primary endpoint was overall mortality at day 30 of follow-up. Secondary endpoints included invasive fungal disease (IFD)-related mortality, number of days of fever, days of hospitalization and use of antifungal drugs, percentage of children developing IFD, requiring modification of initial treatment strategy and need for ICU. The trial was registered with Registro Brasileiro de Ensaios Clínicos (ReBEC) under trial number RBR-3m9d74. Results A total of 149 children were randomized, 73 to empirical therapy and 76 to pre-emptive therapy. Thirty-two out of 76 (42%) children in the pre-emptive group received antifungal therapy. The median duration of antifungal therapy was 11 days in the empirical arm and 6 days in the pre-emptive arm (P < 0.001), with similar overall mortality (8% in the empirical arm and 5% in the pre-emptive arm, P = 0.47). IFD-related mortality was the same in both groups (3%, P = 0.97), as were the percentage of children with IFD (12%, P = 0.92) and the number of days of fever (9, P = 0.76). The number of days of hospitalization was 19 in the empirical arm and 17 in the pre-emptive arm (P = 0.15) and the need for ICU was 25% in the empirical arm and 20% in the pre-emptive arm (P = 0.47). Conclusions Pre-emptive antifungal therapy was as effective as empirical antifungal therapy in children with cancer, fever and neutropenia, significantly reducing the use of antifungal drugs.

Pediatr Blood Cancer 2019; 66:e27887. [PMID: 31250539 DOI: 10.1002/pbc.27887] [Citation(s) in RCA: 25] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2019] [Revised: 06/01/2019] [Accepted: 06/03/2019] [Indexed: 11/12/2022]
Abstract
Routinely measurable biomarkers as predictors for adverse outcomes in febrile neutropenia could improve management through risk stratification. This systematic review assesses the predictive role of biomarkers in identifying events such as bacteraemia, clinically documented infections, microbiologically documented infection, severe sepsis requiring intensive care or high dependency care and death. This review collates 8319 episodes from 4843 patients. C-reactive protein (CRP), interleukin (IL)-6, IL-8 and procalcitonin (PCT) consistently predict bacteraemia and severe sepsis; other outcomes have highly heterogeneous results. Performance of the biomarkers at admission using different thresholds demonstrates that PCT > 0.5 ng/mL offers the best compromise between sensitivity and specificity: sensitivity 0.67 (confidence interval [CI] 0.53-0.79) specificity 0.73 (CI 0.66-0.77). Seventeen studies describe the use of serial biomarkers, with PCT having the greatest discriminatory role. Biomarkers, potentially with serial measurements, may predict adverse outcomes in paediatric febrile neutropenia and their role in risk stratification is promising.

Abstract
Background/aim Bacteremia remains an important cause of morbidity and mortality during febrile neutropenia (FN) episodes. We aimed to define the risk factors for bacteremia in febrile neutropenic children with hemato-oncological malignancies. Materials and methods The records of 150 patients aged ≤18 years who developed FN in hematology and oncology clinics were retrospectively evaluated. Patients with bacteremia were compared to patients with negative blood cultures. Results The mean age of the patients was 7.5 ± 4.8 years. Leukemia was more prevalent than solid tumors (61.3% vs. 38.7%). Bacteremia was present in 23.3% of the patients. Coagulase-negative staphylococci were the most frequently isolated microorganism. Leukopenia, severe neutropenia, positive peripheral blood and central line cultures during the previous 3 months, presence of a central line, previous FN episode(s), hypotension, tachycardia, and tachypnea were found to be risk factors for bacteremia. Positive central line cultures during the previous 3 months and presence of previous FN episode(s) were shown to increase bacteremia risk by 2.4-fold and 2.5-fold, respectively. Conclusion Presence of a bacterial growth in central line cultures during the previous 3 months and presence of any previous FN episode(s) were shown to increase bacteremia risk by 2.4-fold and 2.5-fold, respectively. These factors can predict bacteremia in children with FN.

Abstract
Local and systemic infections are a significant cause of morbidity and mortality among immunocompromised children, including but not limited to patients with hematologic and solid malignancies, congenital or acquired immunodeficiencies, or hematopoietic cell or solid organ transplantation patients. Progression to septic shock can be rapid and profound and thus requires specific diagnostic and treatment approaches. This chapter will discuss the diagnosis and the initial hemodynamic management strategies of septic shock in immunocompromised children, including strategies to improve oxygen delivery, reduce metabolic demand, and monitor hemodynamic response to resuscitation. This chapter also discusses strategies to reverse septic shock pathobiology, including the use of both empiric and targeted anti-infective strategies and pharmacologic and cell therapy-based immunomodulation. Specific consideration is also paid to the management of high-risk subpopulations and the care of septic shock patients with resolving injury.

Abstract
OBJECTIVE To assess the trends of inpatient resource use and mortality in pediatric hospitalizations for fever with neutropenia in the US from 2007 to 2014. STUDY DESIGN Using National (Nationwide) Inpatient Sample (NIS) and International Classification of Diseases, Ninth Revision, Clinical Modification codes, we studied pediatric cancer hospitalizations with fever with neutropenia between 2007 and 2014. Using appropriate weights for each NIS discharge, we created national estimates of median cost, length of stay, and in-hospital mortality rates. RESULTS Between 2007 and 2014, there were 104 315 hospitalizations for pediatric fever with neutropenia. The number of weighted fever with neutropenia hospitalizations increased from 12.9 (2007) to 18.1 (2014) per 100 000 US population. A significant increase in fever with neutropenia hospitalizations trend was seen in the 5- to 14-year age group, male sex, all races, and in Midwest and Western US hospital regions. Overall mortality rate remained low at 0.75%, and the 15- to 19-year age group was at significantly greater risk of mortality (OR 2.23, 95% CI 1.36-3.68, P = .002). Sepsis, pneumonia, meningitis, and mycosis were the comorbidities with greater risk of mortality during fever with neutropenia hospitalizations. Median length of stay (2007: 4 days, 2014: 5 days, P < .001) and cost of hospitalization (2007: $8771, 2014: $11 202, P < .001) also significantly increased during the study period. CONCLUSIONS Our study provides information regarding inpatient use associated with fever with neutropenia in pediatric hospitalizations. Continued research is needed to develop standardized risk stratification and cost-effective treatment strategies for fever with neutropenia hospitalizations considering increasing costs reported in our study. Future studies also are needed to address the greater observed mortality in adolescents with cancer.

Abstract
PURPOSE To validate a clinical risk prediction score (Ammann score) to predict adverse events (AEs) in paediatric febrile neutropenia (FN). PATIENTS AND METHODS Patients <16 years of age were enrolled. A risk prediction score (based on haemoglobin ≥ 9 g/dl, white cell count (WCC) < 0.3 G/l, platelet count <50 G/l and chemotherapy more intensive than acute lymphoblastic leukaemia maintenance therapy) was calculated and AEs were documented. RESULTS In total, 100 FN episodes occurred in 52 patients, male:female ratio was 1.8:1 and median age was 56 months. At reassessment, AEs occurred in 18 of 55 (45%) low-risk FN episodes (score < 9) and 21 of 42 (55%) high-risk episodes (score ≥9) (sensitivity 60%, specificity 65%, positive predictive value 53%, negative predictive value 71%). Total WCC and absolute monocyte count (AMC) were significantly associated with AEs. CONCLUSION This study identified total WCC and AMC as significantly associated with AEs but failed to validate the risk prediction score.

Abstract
BACKGROUND Although a number of risk factors have been associated with invasive fungal disease (IFD), a systematic review of the literature to document pediatric-specific factors has not been performed. METHODS We used the Ovid SP platform to search Medline, Medline In-Process, and Embase for studies that identified risk factors for IFD in children with cancer or those who undergo hematopoietic stem cell transplantation (HSCT). We included studies if they consisted of children or adolescents (<25 years) who were receiving treatment for cancer or undergoing HSCT and if the study evaluated risk factors among patients with and those without IFD. RESULTS Among the 3566 studies screened, 22 studies were included. A number of pediatric factors commonly associated with an increased risk for IFD were confirmed, including prolonged neutropenia, high-dose steroid exposure, intensive-timing chemotherapy for acute myeloid leukemia, and acute and chronic graft-versus-host disease. Increasing age, a factor not commonly associated with IFD risk, was identified as a risk factor in multiple published cohorts. CONCLUSIONS With this systematic review, we have confirmed IFD risk factors that are considered routinely in daily clinical practice. Increasing age should also be considered when assessing patient risk for IFD. Future efforts should focus on defining more precise thresholds for a particular risk factor (ie, age, neutropenia duration) and on development of prediction rules inclusive of individual factors to further refine the risk prediction.

Abstract
BACKGROUND Fever and neutropenia (FN) clinical decision rules (CDRs) are recommended to help distinguish children with cancer at high and low risk of severe infection. The aim of this study was to validate existing pediatric FN CDRs designed to stratify children with cancer at high or low risk of serious infection or medical complication. METHODS Pediatric CDRs suitable for validation were identified from a literature search. Relevant data were extracted from an existing data set of 650 retrospective FN episodes in children with cancer. The sensitivity and specificity of each of the CDR were compared with the derivation studies to assess reproducibility. RESULTS Six CDRs were identified for validation: 2 were designed to predict bacteremia and 4 to predict adverse events. Five CDRs exhibited reproducibility in our cohort. A rule predicting bacteremia had the highest sensitivity (100%; 95% confidence interval (CI): 93%-100%) although poor specificity (17%), with only 15% identified as low risk. For adverse events, the highest sensitivity achieved was 84% (95% CI: 75%-90%), with specificity of 29% and 27% identified as low risk. A rule intended for application after a 24-hour period of inpatient observation yielded a sensitivity of 80% (95% CI: 73-86) and specificity of 46%, with 44% identified as low risk. CONCLUSIONS Five CDRs were reproducible, although not all can be recommended for implementation because of either inadequate sensitivity or failure to identify a clinically meaningful number of low-risk patients. The 24-hour rule arguably exhibits the best balance between sensitivity and specificity in our population.

Abstract
UNLABELLED It is not clear if children with high fever are at increased risk for serious bacterial infection (SBI). Our aim was to systematically review if children suffering from high fever are at high risk for SBI. Our data sources were Embase, Medline, and Pubmed; from their inception until the last week of March 2017. The study selection were of cohort and case control studies comparing the incidence of SBI in children with hyperpyrexia with children with fever of 41 °C or less, and children with a temperature higher than 40 °C, with children with fever of 40 °C or less. Two reviewers independently pooled studies for detailed review using a structured data-collection form. We calculated the odds ratio and 95% confidence intervals (CI) for SBI, assuming a random-effects model. A sub-group analysis was conducted. In our results, 11 studies met the inclusion criteria. Two studies showed that children with hyperpyrexia are at higher risk for SBI (OR 1.96 95% CI 1.3-1.97). An increased risk for SBI in children with high fever (OR 3.21 95% CI 1.67; 6.22). SBI in infants with temperature over 40 °C was higher compared to infants with lower degree of fever (OR 6.3 95% CI 4.44; 8.95). On older children, the risk for SBI was only slightly higher in children with fever above 40 °C. The limitation of the study is the small amount of studies and that the heterogeneity of the studies was very high. CONCLUSION Young infants with temperature higher than 400 °C are at increased risk for SBI. Risk of SBI in older children with temperature > 400C is minimal. What is known: • An association between high fever and increased risk for SBI was reported in young infants. • Based on only two studies from the 1970s and 1980s, hyperpyrexia is associated with increased risk for SBI. What is new: • Infants under the age of 3 months with fever > 40 °C were found to have increased risk for SBI. • Risk of SBI in older children with temperature > 40 °C is minimal.

Pediatr Blood Cancer 2018; 65:10.1002/pbc.26790. [PMID: 28895277 PMCID: PMC6051353 DOI: 10.1002/pbc.26790] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2017] [Revised: 08/11/2017] [Accepted: 08/14/2017] [Indexed: 12/24/2022]
Abstract
BACKGROUND In low- and middle-income countries (LMICs), inconsistent or delayed management of fever contributes to poor outcomes among pediatric patients with cancer. We hypothesized that standardizing practice with a clinical algorithm adapted to local resources would improve outcomes. Therefore, we developed a resource-specific algorithm for fever management in Davao City, Philippines. The primary objective of this study was to evaluate adherence to the algorithm. PROCEDURE This was a prospective cohort study of algorithm adherence to assess the types of deviation, reasons for deviation, and pathogens isolated. All pediatric oncology patients who were admitted with fever (defined as an axillary temperature >37.7°C on one occasion or ≥37.4°C on two occasions 1 hr apart) or who developed fever within 48 hr of admission were included. Univariate and multiple linear regression analyses were used to determine the relation between clinical predictors and length of hospitalization. RESULTS During the study, 93 patients had 141 qualifying febrile episodes. Even though the algorithm was designed locally, deviations occurred in 70 (50%) of 141 febrile episodes on day 0, reflecting implementation barriers at the patient, provider, and institutional levels. There were 259 deviations during the first 7 days of admission in 92 (65%) of 141 patient episodes. Failure to identify high-risk patients, missed antimicrobial doses, and pathogen isolation were associated with prolonged hospitalization. CONCLUSIONS Monitoring algorithm adherence helps in assessing the quality of pediatric oncology care in LMICs and identifying opportunities for improvement. Measures that decrease high-frequency/high-impact algorithm deviations may shorten hospitalizations and improve healthcare use in LMICs.

Abstract
Introduction This study was planned to explore the clinical and hematological profile of febrile neutropenia (FN) in Indian children with focus on correlation of degree of neutropenia with fever and procalcitonin (PCT) level and the utility of serum PCT levels in cases of FN. Materials and Methods Children below 12 years, receiving chemotherapy for hematological malignancy having oral temperature more than 100°F and absolute neutrophil count (ANC) below 500/mm3 were included. The aim of this study was to observe the clinicohematological profile of FN and utility of serum PCT levels in neutropenic patients. PCT was done by two-step two-site electrochemiluminescence immunoassay. Serum PCT values were reported as nanogram/ml. Results Four categories were made based on serum PCT levels which had negative correlation with ANC but no correlation with microbiologically detected infections. Discussion PCT is generally used to support the diagnosis of bacterial infection or sepsis in the emergency department or to monitor the treatment of sepsis with regard to reviewing antimicrobial treatment. The use of PCT has been well established as a marker for infection in adults and in nonneutropenic children, but similar data are lacking in pediatric population, more so in children with FN in Indian contexts. This study aims to fulfill this lacuna. Conclusion The higher levels of PCT had a high negative correlation with ANC but low correlation with microbiologically detected infections.

Abstract
BACKGROUND Infection is the most important cause of treatment-related morbidity and mortality in pediatric patients treated for acute lymphoblastic leukemia (ALL). Although routine in adults with leukemia, antibacterial prophylaxis is controversial in pediatrics because of insufficient evidence for its efficacy or antibiotic choice and concerns about promoting antibiotic resistance and Clostridium difficile infection. METHODS This was a single-center, observational cohort study of patients with newly diagnosed ALL, comparing prospectively collected infection-related outcomes in patients who received no prophylaxis, levofloxacin prophylaxis, or other prophylaxis during induction therapy on the total XVI study. A propensity score-weighted logistic regression model was used to adjust for confounders. RESULTS Of 344 included patients, 173 received no prophylaxis, 69 received levofloxacin prophylaxis, and 102 received other prophylaxis regimens. Patients receiving prophylaxis had longer duration of neutropenia. Prophylaxis reduced the odds of febrile neutropenia, likely bacterial infection, and bloodstream infection by ≥70%. Levofloxacin prophylaxis alone reduced these infections, but it also reduced cephalosporin, aminoglycoside, and vancomycin exposure and reduced the odds of C. difficile infection by >95%. No increase in breakthrough infections with antibiotic-resistant organisms was seen, but this cannot be excluded. CONCLUSIONS This is the largest study to date of antibacterial prophylaxis during induction therapy for pediatric ALL and the first to include a broad-spectrum fluoroquinolone. Prophylaxis prevented febrile neutropenia and systemic infection. Levofloxacin prophylaxis also minimized the use of treatment antibiotics and drastically reduced C. difficile infection. Although long-term antibiotic-resistance monitoring is needed, these data support using targeted prophylaxis with levofloxacin in children undergoing induction chemotherapy for ALL.

Br J Cancer 2017; 117:171-178. [PMID: 28609435 PMCID: PMC5520507 DOI: 10.1038/bjc.2017.154] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2016] [Revised: 05/09/2017] [Accepted: 05/11/2017] [Indexed: 12/04/2022] Open
Abstract
BACKGROUND The aim of this study was to validate the 'Predicting Infectious ComplicatioNs in Children with Cancer' (PICNICC) clinical decision rule (CDR) that predicts microbiologically documented infection (MDI) in children with cancer and fever and neutropenia (FN). We also investigated costs associated with current FN management strategies in Australia. METHODS Demographic, episode, outcome and cost data were retrospectively collected on 650 episodes of FN. We assessed the discrimination, calibration, sensitivity and specificity of the PICNICC CDR in our cohort compared with the derivation data set. RESULTS Using the original variable coefficients, the CDR performed poorly. After recalibration the PICNICC CDR had an area under the receiver operating characteristic (AUC-ROC) curve of 0.638 (95% CI 0.590-0.685) and calibration slope of 0.24. The sensitivity, specificity, positive predictive value and negative predictive value of the PICNICC CDR at presentation was 78.4%, 39.8%, 28.6% and 85.7%, respectively. For bacteraemia, the sensitivity improved to 85.2% and AUC-ROC to 0.71. Application at day 2, taking into consideration the proportion of MDI known (43%), further improved the sensitivity to 87.7%. Length of stay is the main contributor to cost of FN treatment, with an average cost per day of AUD 2183 in the low-risk group. CONCLUSIONS For prediction of any MDI, the PICNICC rule did not perform as well at presentation in our cohort as compared with the derivation study. However, for bacteraemia, the predictive ability was similar to that of the derivation study, highlighting the importance of recalibration using local data. Performance also improved after an overnight period of observation. Implementation of a low-risk pathway, using the PICNICC CDR after a short period of inpatient observation, is likely to be safe and has the potential to reduce health-care expenditure.

Abstract
PURPOSE The study aims to validate a score predicting risk of complications in pediatric patients with chemotherapy-related febrile neutropenia (FN) and evaluate the performance of previously published models for risk stratification. PATIENTS AND METHODS Children diagnosed with cancer and presenting with FN were evaluated in a prospective single-center study. A score predicting the risk of complications, previously derived in the unit, was validated on a prospective cohort. Performance of six predictive models published from geographically distinct settings was assessed on the same cohort. RESULTS Complications were observed in 109 (26.3%) of 414 episodes of FN over 15 months. A risk score based on undernutrition (two points), time from last chemotherapy (<7 days = two points), presence of a nonupper respiratory focus of infection (two points), C-reactive protein (>60 mg/l = five points), and absolute neutrophil count (<100 per μl = two points) was used to stratify patients into "low risk" (score <7, n = 208) and assessed using the following parameters: overall performance (Nagelkerke R2 = 34.4%), calibration (calibration slope = 0.39; P = 0.25 in Hosmer-Lemeshow test), discrimination (c-statistic = 0.81), overall sensitivity (86%), negative predictive value (93%), and clinical net benefit (0.43). Six previously published rules demonstrated inferior performance in this cohort. CONCLUSION An indigenous decision rule using five simple predefined variables was successful in identifying children at risk for complications. Prediction models derived in developed nations may not be appropriate for low-middle-income settings and need to be validated before use.

Abstract
Purpose To update a clinical practice guideline (CPG) for the empirical management of fever and neutropenia (FN) in children with cancer and hematopoietic stem-cell transplantation recipients. Methods The International Pediatric Fever and Neutropenia Guideline Panel is a multidisciplinary and multinational group of experts in pediatric oncology and infectious diseases that includes a patient advocate. For questions of risk stratification and evaluation, we updated systematic reviews of observational studies. For questions of therapy, we conducted a systematic review of randomized trials of any intervention applied for the empirical management of pediatric FN. The Grading of Recommendation Assessment, Development and Evaluation approach was used to make strong or weak recommendations and to classify levels of evidence as high, moderate, low, or very low. Results Recommendations related to initial presentation, ongoing management, and empirical antifungal therapy of pediatric FN were reviewed; the most substantial changes were related to empirical antifungal therapy. Key differences from our 2012 FN CPG included the listing of a fourth-generation cephalosporin for empirical therapy in high-risk FN, refinement of risk stratification to define patients with high-risk invasive fungal disease (IFD), changes in recommended biomarkers and radiologic investigations for the evaluation of IFD in prolonged FN, and a weak recommendation to withhold empirical antifungal therapy in IFD low-risk patients with prolonged FN. Conclusion Changes to the updated FN CPG recommendations will likely influence the care of pediatric patients with cancer and those undergoing hematopoietic stem-cell transplantation. Future work should focus on closing research gaps and on identifying ways to facilitate implementation and adaptation.

Efficacy and safety of withholding antimicrobial treatment in children with cancer, fever and neutropenia, with a demonstrated viral respiratory infection: a randomized clinical trial. Clin Microbiol Infect 2017; 23:173-178. [PMID: 27856269 PMCID: PMC7129180 DOI: 10.1016/j.cmi.2016.11.001] [Citation(s) in RCA: 36] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2016] [Revised: 11/03/2016] [Accepted: 11/04/2016] [Indexed: 11/28/2022]
Abstract
OBJECTIVES To determine efficacy and safety of withholding antimicrobials in children with cancer, fever and neutropenia (FN) with a demonstrated respiratory viral infection. METHODS Prospective, multicentre, randomized study in children presenting with FN at five hospitals in Santiago, Chile, evaluated at admission for diagnosis of bacterial and viral pathogens including PCR-microarray for 17 respiratory viruses. Children positive for a respiratory virus, negative for a bacterial pathogen and with a favourable evolution after 48 h of antimicrobial therapy were randomized to either maintain or withhold antimicrobials. Primary endpoint was percentage of episodes with uneventful resolution. Secondary endpoints were days of fever/hospitalization, bacterial infection, sepsis, admission to paediatric intensive care unit (PICU) and death. RESULTS A total of 319 of 951 children with FN episodes recruited between July 2012 and December 2015 had a respiratory virus as a unique identified microorganism, of which 176 were randomized, 92 to maintain antimicrobials and 84 to withdraw. Median duration of antimicrobial use was 7 days (range 7-9 days) versus 3 days (range 3-4 days), with similar frequency of uneventful resolution (89/92 (97%) and 80/84 (95%), respectively, not significant; OR 1.48; 95% CI 0.32-6.83, p 0.61), and similar number of days of fever (2 versus 1), days of hospitalization (6 versus 6) and bacterial infections throughout the episode (2%-1%), with one case of sepsis requiring admission to PICU in the group that maintained antimicrobials, without any deaths. CONCLUSIONS The reduction of antimicrobials in children with FN and respiratory viral infections, based on clinical and microbiological/molecular diagnostic criteria, should favour the adoption of evidence-based management strategies in this population.

Hemming V, Jakes AD, Shenton G, Phillips B. Prospective cohort study of procalcitonin levels in children with cancer presenting with febrile neutropenia. BMC Pediatr 2017; 17:2. [PMID: 28056911 PMCID: PMC5217195 DOI: 10.1186/s12887-016-0766-8] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2015] [Accepted: 12/21/2016] [Indexed: 11/25/2022] Open
Abstract
Background Febrile neutropenia (FNP) causes significant morbidity and mortality in children undergoing treatment for cancer. The development of clinical decision rules to help stratify risks in paediatric FNP patients and the use of inflammatory biomarkers to identify high risk patients is an area of recent research. This study aimed to assess if procalcitonin (PCT) levels could be used to help diagnose or exclude severe infection in children with cancer who present with febrile neutropenia, both as a single measurement and in addition to previously developed clinical decision rules. Methods This prospective cohort study of a diagnostic test included patients between birth and 18 years old admitted with febrile neutropenia to the Paediatric Oncology and Haematology Ward in Leeds between 1st October 2012 and 30th September 2013. Each admission with FNP was treated as a separate episode. Blood was taken for a procalcitonin level at admission with routine investigations. ‘R’ was used for statistical analysis. Likelihood ratios were calculated and multivariable logistic regression. Results Forty-eight episodes from 27 patients were included. PCT >2 ng/dL was strongly associated with increased risk of severe infection (likelihood ratio of 26 [95% CI 3.5, 190]). The data suggests that the clinical decision rules are largely ineffective at risk stratification, frequently over-stating the risk of individual episodes. High procalcitonin levels on admission are correlated with a greatly increased risk of severe infection. Conclusions This study does not show a definitive benefit in using PCT in FNP though it supports further research on its use. The benefit of novel biomarkers has not been proven and before introducing new tests for patients it is important their benefit above existing features is proven, particularly due to the increasing importance of health economics.
