Safety of empirical antibiotic therapy discontinuing for fever of unknown origin during high-risk neutropenia in children. J Infect 2024; 88:106171. [PMID: 38697268 DOI: 10.1016/j.jinf.2024.106171] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Revised: 04/19/2024] [Accepted: 04/24/2024] [Indexed: 05/04/2024]
Abstract
BACKGROUND ECIL-2021 recommends discontinuing empirical antibiotic therapy (EAT) in febrile-neutropenic children after 72 h of treatment and at least 24-48 h of apyrexia in the case of fever of unknown origin (FUO). These guidelines are rarely applied to high-risk children's neutropenia. MATERIAL AND METHODS We retrospectively included all consecutive FUO episodes occurring during profound neutropenia ≥ 10 days in children in our institution. We evaluated the safety of EAT discontinuation in patients for whom the ECIL guidelines were followed compared to those for whom they didn't. We used a combined criterion of mortality and intensive care unit admission at 30 days. We identified risk factors for recurrent fever after EAT discontinuation. RESULTS Fifty-one FUO episodes occurred in 37 patients. EAT discontinuation followed ECIL guidelines in 19 (37 %) episodes. No deaths and-or transfers in ICU occurred in the ECIL group. The duration of EAT was shorter by nine days in the group following ECIL guidelines (p < 0.001). We observed 14 (27 %) episodes of recurrent fever. Mucositis was significantly associated with recurrent fever (p < 0.01). CONCLUSION EAT discontinuation seems feasible and safe in FUO during prolonged febrile neutropenia in children. However, mucosal lesions should prompt thorough surveillance due to the risk of recurrent fever.

Abstract
Chemotherapy drug administration is a complex problem that often requires expensive clinical trials to evaluate potential regimens; one way to alleviate this burden and better inform future trials is to build reliable models for drug administration. This paper presents a mixed-integer program for combination chemotherapy (utilization of multiple drugs) optimization that incorporates various important operational constraints and, besides dose and concentration limits, controls treatment toxicity based on its effect on the count of white blood cells. To address the uncertainty of tumor heterogeneity, we also propose chance constraints that guarantee reaching an operable tumor size with a high probability in a neoadjuvant setting. We present analytical results pertinent to the accuracy of the model in representing biological processes of chemotherapy and establish its potential for clinical applications through a numerical study of breast cancer.

Dissecting bloodstream infections in febrile neutropenic patients with hematological malignancies, a decade-long single center retrospective observational study (2009-2019). J Infect Public Health 2024; 17:152-162. [PMID: 38029491 DOI: 10.1016/j.jiph.2023.11.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2023] [Revised: 11/07/2023] [Accepted: 11/13/2023] [Indexed: 12/01/2023] Open
Abstract
BACKGROUND The use of ill-suited antibiotics is a significant risk factor behind the increase in the mortality, morbidity, and economic burden for patients who are under treatment for hematological malignancy (HM) and bloodstream infections (BSI). Such unfitting treatment choices intensify the evolution of resistant variants which is a public health concern due to possible healthcare-associated infection spread to the general population. Hence, this study aims to evaluate antibiograms of patients with BSI and risk factors associated with septicemia. METHODS A total of 1166 febrile neutropenia episodes (FNE) among 513 patients with HM from the National Center for Cancer Care and Research (NCCCR), Qatar, during 2009-2019 were used for this study. The socio-demographic, clinical, microbial, and anti-microbial data retrieved from the patient's health records were used. RESULTS We analyzed the sensitivity of gram-negative and gram-positive bacilli reported in HM-FN-BSI patients. Out of the total 512 microorganisms isolated, 416 (81%) were gram-negative bacteria (GNB), 76 (15%) were gram-positive bacteria (GPB) and 20 (4%) were fungi. Furthermore, in 416 GNB, 298 (71.6%) were Enterobacteriaceae sp. among which 121 (41%) were ESBL (Extended Spectrum Beta-Lactamase) resistant to Cephalosporine third generation and Piperacillin-Tazobactam, 54 (18%) were Carbapenem-resistant or multidrug-resistant organism (MDRO). It's noteworthy that the predominant infectious agents in our hospital include E. coli, Klebsiella species, and P. aeruginosa. Throughout the study period, the mortality rate due to BSI was 23%. Risk factors that show a significant correlation with death are age, disease status, mono or polymicrobial BSI and septic shock. CONCLUSION Decision pertaining to the usage of antimicrobials for HM-FN-BSI patients is a critical task that relies on the latest pattern of prevalence, treatment resistance, and clinical outcomes. Analysis of the antibiogram of HM-FN-BSI patients in Qatar calls for a reconsideration of currently followed empirical antibiotic therapy towards better infection control and antimicrobial stewardship.

Curr Microbiol 2023; 81:10. [PMID: 37978091 PMCID: PMC10656328 DOI: 10.1007/s00284-023-03506-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Accepted: 09/27/2023] [Indexed: 11/19/2023]
Abstract
Fungal-contaminated compounded pharmaceuticals and medical devices pose a public health problem. This review aimed to provide an organized overview of the literature on that critical issue. Firstly, it was found that compounding pharmacies can produce drugs that are contaminated with fungi, leading to outbreaks of severe fungal diseases. Secondly, inadequate sterile compounding techniques or storage conditions, or exceeding the limit of a fungal count, can result in fungal contamination. Lastly, nanotools can be used to rapidly detect fungi, thus improving fungal diagnostic procedures. To achieve this goal, we have reviewed the published data on PubMed, the CDC, and FDA Web sites, and a literature search was undertaken to identify severe fungal infections associated with compounding pharmacies outside of hospitals, limited by the dates 2003 to 2021. The "Preferred Reporting Items for Critical Reviews" were followed in searching, including, and excluding papers. Fungal outbreaks have been documented due to contaminated pharmaceuticals and medical devices. In 2013, 55 people died from fungal meningitis caused by contaminated steroid injections containing methylprednisolone acetate. Additionally, in 2021, Aspergillus penicillioides contamination was reported in ChloraPrep drugs, which was attributed to the storage conditions that were conducive to the growth of this fungus. These incidents have resulted in severe infectious diseases, such as invasive mycoses, cornea infections, Endophthalmitis, and intestinal and gastric mycosis. By implementing preventive measures and policies, it is possible to avoid these outbreaks. Creating Nano-diagnostics presents a major challenge, where promptly diagnosing fungal infections is required to determine the proper corrective and preventive measures.

Defining research priorities and needs in cancer symptoms for adults diagnosed with cancer: an Australian/New Zealand modified Delphi study. Support Care Cancer 2023; 31:436.

Abstract
PURPOSE This study asked consumers (patients, carers) and healthcare professionals (HCPs) to identify the most important symptoms for adults with cancer and potential treatment interventions. METHODS A modified Delphi study was conducted involving two rounds of electronic surveys based on prevalent cancer symptoms identified from the literature. Round 1 gathered information on participant demographics, opinions and/or experience on cancer symptom frequency and impact, and suggestions for interventions and/or service delivery models for further research to improve management of cancer symptoms. In Round 2, respondents ranked the importance of the top ten interventions identified in Round 1. In Round 3, separate expert panels of consumers and healthcare professionals (HCPs) attempted to reach consensus on the symptoms and interventions previously identified. RESULTS Consensus was reached for six symptoms across both groups: fatigue, constipation, diarrhoea, incontinence, and difficulty with urination. Notably, fatigue was the only symptom to reach consensus across both groups in Round 1. Similarly, consensus was reached for six interventions across both groups. These were the following: medicinal cannabis, physical activity, psychological therapies, non-opioid interventions for pain, opioids for breathlessness and cough, and other pharmacological interventions. CONCLUSIONS Consumers and HCPs prioritise differently; however, the symptoms and interventions that reached consensus provide a basis for future research. Fatigue should be considered a high priority given its prevalence and its influence on other symptoms. The lack of consumer consensus indicates the uniqueness of their experience and the need for a patient-centred approach. Understanding individual consumer experience is important when planning research into better symptom management.

Abstract
BRCA1 and BRCA2 play a central role in DNA repair and their germline pathogenic variants (gBRCA) confer a high risk for developing breast and ovarian cancer. Standard chemotherapy regimens for these cancers include DNA-damaging agents. We hypothesized that gBRCA carriers might be at higher risk of developing chemotherapy-related hematologic toxicity and therapy-related myeloid neoplasms (t-MN). We conducted a retrospective study of women newly diagnosed with invasive breast or ovarian cancer who were screened for gBRCA1/gBRCA2 at Geneva University Hospitals. All patients were treated with (neo-)adjuvant chemotherapy. We evaluated acute hematologic toxicities by analyzing the occurrence of febrile neutropenia and severe neutropenia (grade 4) at day 7-14 of the first cycle of chemotherapy and G-CSF use during the entire chemotherapy regimen. Characteristics of t-MN were collected. We reviewed medical records from 447 patients: 58 gBRCA1 and 40 gBRCA2 carriers and 349 non-carriers. gBRCA1 carriers were at higher risk of developing severe neutropenia (32% vs. 14.5%, p = 0.007; OR = 3.3, 95% CI [1.6-7], p = 0.001) and of requiring G-CSF for secondary prophylaxis (58.3% vs. 38.2%, p = 0.011; OR = 2.5, 95% CI [1.4-4.8], p = 0.004). gBRCA2 carriers did not show increased acute hematologic toxicities. t-MN were observed in 2 patients (1 gBRCA1 and one non-carrier). Our results suggested an increased acute hematologic toxicity upon exposure to chemotherapy for breast and ovarian cancer among gBRCA1 but not gBRCA2 carriers. A deeper characterization of t-MN is warranted with the recent development of PARP inhibitors in frontline therapy in gBRCA breast and ovarian cancer.

Abstract
Background An escalation in cases of rhinomaxillary mucormycosis among post-COVID patients is being reported. However, there is limited information about periodontal features in mucormycosis cases. This study explored the periodontal signs and symptoms among post-COVID mucormycosis individuals. Materials and Methods This cross-sectional study was carried out with a total of 25 post-COVID mucormycosis patients attending tertiary care public teaching hospital. Clinical and radiographic assessments were done. Results An elevation in mean probing pocket depth (PPD) up to 6.21 ± 2.7 mm was noted. Nearly 16%-40% of patients had Miller's Grade III mobility in the affected site. Forty-four per cent had localized single or multiple abscess, 40% had palatal swelling, 32% had necrosis of soft tissue and bone exposure, and 52% had maxillary dentoalveolar segmental mobility in the affected site. Radiographic examination revealed varying stages of interdental bone loss. Conclusion The present study observed an increase in mobility and mean PPD which did not commiserate with interdental bone loss in the affected maxillary region.

Abstract
The haematopoietic system plays an essential role in our health and survival. It is comprised of a range of mature blood and immune cell types, including oxygen-carrying erythrocytes, platelet-producing megakaryocytes and infection-fighting myeloid and lymphoid cells. Self-renewing multipotent haematopoietic stem cells (HSCs) and a range of intermediate haematopoietic progenitor cell types differentiate into these mature cell types to continuously support haematopoietic system homeostasis throughout life. This process of haematopoiesis is tightly regulated in vivo and primarily takes place in the bone marrow. Over the years, a range of in vitro culture systems have been developed, either to expand haematopoietic stem and progenitor cells or to differentiate them into the various haematopoietic lineages, based on the use of recombinant cytokines, co-culture systems and/or small molecules. These approaches provide important tractable models to study human haematopoiesis in vitro. Additionally, haematopoietic cell culture systems are being developed and clinical tested as a source of cell products for transplantation and transfusion medicine. This review discusses the in vitro culture protocols for human HSC expansion and differentiation, and summarises the key factors involved in these biological processes.

Abstract
INTRODUCTION Infectious complications, particularly invasive bacterial and fungal infections, are still a major cause of morbidity in pediatric cancer patients and are associated with significant mortality. Over the last few years, there has been much effort in defining risk groups to tailor antimicrobial therapy, and in establishing pediatric-specific guidelines for antimicrobial strategies. AREAS COVERED This review provides a critical overview of defining risk groups for infection, diagnostic work-up, antimicrobial prophylaxis, empirical therapy, and treatment of established infections. EXPERT OPINION To date, no generalizable risk prediction model has been established for pediatric cancer patients. There is growing interest in defining the impact of the individual genetic background on infectious complications. New diagnostic tools have been developed over the last few years, but they need to be validated in pediatric cancer patients. International, pediatric-specific guidelines for antimicrobial prophylaxis, empirical therapy, and treatment of established infections have recently been published and will harmonize antimicrobial strategies in the future.

Risk of Bacterial, Viral, and Fungal Infections in Patients With Solid Malignant Tumors Treated With Curative Intent Radiation Therapy. Adv Radiat Oncol 2022; 7:100950. [PMID: 35677193 PMCID: PMC9168504 DOI: 10.1016/j.adro.2022.100950] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2021] [Accepted: 03/16/2022] [Indexed: 10/31/2022] Open
Abstract
Purpose The incidence, etiology, and association of infections with radiation therapy (RT)-induced lymphopenia in patients with solid tumors is not well elucidated. Methods and Materials We identified possible, probable, and definite infections caused by bacteria, fungi, and viruses, combining data on medication, microbiology, and diagnoses. Definite infections had either a diagnosis or a positive microbiological isolation. We analyzed the incidence and adjusted incidence-rate ratio of infections in the year after the start of RT among patients who received RT plus chemotherapy and RT monotherapy, by type of infection and according to the degree of RT-induced lymphopenia. Results A total of 4450 of 6334 (70.3%) patients experienced 11264 infections overall; 1424 (22.5%) patients developed 2104 definite infections in the first year after RT. Infections were more frequent among patients who received RT plus chemotherapy (2590 of 3469; incidence: 16.5 [95% confidence interval {CI}, 16.1-17.0], per 100 patient-years) compared with patients who received RT monotherapy (1860 of 2865; incidence: 12.7 [95% CI, 12.3-13.2]). The incidence of infection was highest in the first 3 months overall (28.2 vs 18.0 in patients who received RT plus chemotherapy compared with those who received RT monotherapy) and for definite infections (4.7 vs 3.8). The proportion of specific bacterial infections were similar among patients who received RT plus chemotherapy versus those who received RT monotherapy. Urinary tract infections were the most frequent (51.2% vs 56.2%), followed by pneumonias (24.1% vs 22.4%). Viral and fungal infections were more frequent among patients who received RT plus chemotherapy, but they were uncommon. In multivariable analyses, patients who received RT plus chemotherapy with a lymphopenia grade of 1-2 or ≥3 versus no lymphopenia at end of RT had an increased risk of bacterial infections 0 to 3 months after RT (incidence rate ratio, 1.45 [95% CI, 1.06-1.97] and 1.71 [95% CI, 1.26-2.34], respectively). Limiting to definite bacterial infections, the incidence rate ratio for lymphopenia grade ≥3 versus no lymphopenia was 2.66 (95% CI, 1.40-5.03). Conclusions The incidence of bacterial infections 0 to 3 months after RT plus chemotherapy for solid tumors was high, especially among patients with RT-induced lymphopenia grade 1-2 and ≥3.

Abstract
The severe acute respiratory syndrome coronavirus (SARS-CoV-2) pandemic has disrupted normal health care utilization patterns worldwide, including decreasing emergency department (ED) visits for various medical emergencies. We examined whether this pattern was present in febrile pediatric oncology patients. In this single-center cohort study, we conducted a retrospective chart review of ED visits of febrile pediatric oncology patients during the first 4 months of the global SARS-CoV-2 pandemic and compared those data to the same time periods in the previous 2 years. During the first 5 months of the pandemic, 25 pediatric oncology patients with fever visited our ED; 65 children visited during the same time period in 2018; and 60 visited in 2019. Compared with 2018 and 2019, encounters for 2020 were decreased by 62% and 58%, respectively. A significantly higher percentage of febrile pediatric oncology patients (84%) were admitted to our hospital during the pandemic compared the previous years (58%). Of concern is the possibility that fear of exposure to coronavirus disease-19 (COVID-19) at our health care facility prompted caregivers of pediatric oncology patients to avoid seeking care for their child with fever. Consistent communication with families about the life-threatening nature of fever should be prioritized among pediatric oncology providers.

Abstract
BACKGROUND: Febrile neutropenia occurs in more than 80% of patients with hematological malignances specially after chemotherapy cycles and an infectious source is identified in approximately 20–30%. Various bacterial, viral, and fungal pathogen contribute to the development of neutropenic fever and without prompt antibiotic therapy mortality rate can be as high as 70%.
AIM: The objective of the study was to document the current sites of infection in patients with febrile neutropenia in hematological ward in Baghdad Teaching Hospital, the microorganisms and antibiotic susceptibly in culture positive cases and mortality rate in 1 week and 4 weeks after episode of fever.
PATIENTS AND METHODS: One hundred cases of febrile neutropenia were evaluated in Hematological Ward of Baghdad Teaching Hospital from January 2019 to January 2020. Detailed history, physical examination, and laboratory investigations were conducted and statistical analysis of the results was done.
RESULTS: One hundred cases of febrile neutropenia, mean age of presentation was 41.56 ± 10.5 years. Acute myeloid leukemia (36%) and acute lymphocytic leukemia (26%) were the most common underlying hematological disorder, followed by Aplastic Anemia, Non-Hodgkin Lymphoma, and Hodgkin Lymphoma. Temperature ranged from 38°C to 39°C with mean temperature of 38.4°C and most of the patient presented with short duration of fever, 57% had absolute neutrophil count below 150 cells/μL with mean duration of neutropenia was 14.01 days. Respiratory tract was the most common site of infection (52%) followed by urinary tract (18%) and in 16% had no obvious focus of infection. Thirty percent of cases were culture Gram-positive and Gram-negative microorganism which were more common 62.9% which were generally sensitive to Aminoglycosides while Gram-positive microorganism constituted 29.6% of isolated bacteria and were generally sensitive to vancomycin. No mortality documented 1 and 4 weeks after fever.
CONCLUSION: We concluded that the most frequent sites of infection in patient with febrile neutropenia were respiratory tract followed by urinary tract infection, while 16% had undetermined source of infection. Thirty percent of patients had a positive blood culture with Escherichia coli being the most common infecting microorganism, Gram-negative microorganisms were more common than Gram-positive microorganism and fungal infection constituted about 6% of growth. Significant association was found between the fever and longer duration of neutropenia and the greater severity of neutropenia was observed. No mortality related to febrile neutropenia was documented.

Abstract
IMPORTANCE Prevention of chemotherapy-induced neutropenia (CIN) and its clinical consequences is an unmet need for which plinabulin, a selective immunomodulating microtubule-binding agent, is being tested. OBJECTIVE To demonstrate noninferiority between plinabulin and pegfilgrastim for days of severe neutropenia in cycle 1 in patients with solid tumors treated with docetaxel. DESIGN, SETTING, AND PARTICIPANTS The Plinabulin vs Pegfilgrastim for the Prevention of Docetaxel-Induced Neutropenia in Patients With Solid Tumors (PROTECTIVE-1) double-blind phase 3 randomized clinical trial was performed in multiple centers in China, Russia, Ukraine, and the US. Participants included patients with breast, prostate, or non-small cell lung cancer treated with single-agent docetaxel chemotherapy. Data were collected from June 1, 2018, to January 31, 2019. The database was locked on February 18, 2021. Data analysis was based on intention to treat and safety and performed from October 5, 2018, to February 23, 2021. INTERVENTIONS Plinabulin, 40 mg, plus placebo or pegfilgrastim, 6 mg, plus placebo. MAIN OUTCOMES AND MEASURES The primary end point was day of severe neutropenia in cycle 1. Additional end points included clinical consequences of CIN (febrile neutropenia, hospitalizations, infections, antibiotic use, and modifications of chemotherapy dose), patient-reported outcomes for bone pain score, markers for immune suppression (neutrophil-to-lymphocyte ratio [NLR] of >5), immature neutrophils (band, promyelocyte, and myelocyte counts >0), and safety. RESULTS Among the 105 patients included in the analysis (65 [6.19%] women; median age, 59 [range, 31-81] years), the primary end point was met within a noninferiority margin of 0.65 days, with a mean difference of 0.52 days (98.52% CI, 0.40-0.65 days). Grade 4 neutropenia frequency in cycle 1 was not significantly different. Plinabulin had earlier onset of action with less grade 4 neutropenia in week 1 of cycle 1. Plinabulin had fewer adverse clinical consequences with rates of febrile neutropenia (0 of 52 vs 1 of 53 [1.9%]), infections (4 of 52 [7.7%] vs 8 of 53 [15.1%]), chemotherapy dose delay of more than 7 days (2 of 52 [3.8%] vs 3 of 53 [5.7%]), and permanent chemotherapy discontinuation (7 of 52 [13.5%] vs 14 of 53 [26.4%]). Patients receiving plinabulin had significantly less bone pain (difference, -0.67 [95% CI, -1.17 to -0.16]; P = .01) and a better immunosuppressive profile (NLR >5 at day 8, 2 of 52 [3.8%] vs 24 of 51 [46.0%]; P < .001). Plinabulin was well tolerated, with comparable safety to pegfilgrastim. CONCLUSIONS AND RELEVANCE Plinabulin has comparable efficacy to pegfilgrastim for the prevention of CIN, with better safety and a better immunosuppressive profile. Plinabulin's same-day dosing compared with pegfilgrastim's next-day dosing offers distinct advantages, including reducing use of health care services.

Abstract
Children with cancer require central venous access which carries risk for line-related infections. The necessity of peripheral and central blood cultures is debated for those with fevers. We evaluated and described results for first episode of paired blood cultures from children with cancer who have a central venous line using retrospective database. Blood culture results, laboratory data, and medical outcomes were included. Descriptive analyses of blood culture results and clinical data were performed. There were 190 episodes of paired positive blood cultures with 167 true positive episodes. Of the true positive episodes, 104 (62.3%) were positive in both central and peripheral cultures, 42 (25.1%) were positive in central only cultures, and 21 (12.6%) were positive in peripheral cultures only. Intensive care unit admission within 48 hours after blood cultures (n=33) differed significantly: 28.7% for both central and peripheral, 10% for central only, and 0% for peripheral only (P=0.009). Central line removal (n=34) differed by type of positivity but was not significant: 22.1% for both central and peripheral, 23.8% for central only, and 4.8% for peripheral only (P=0.15). Peripheral blood cultures provided important medical information yet had differences in short-term clinical outcomes. Further evaluation of medical decision making is warranted.

Abstract
BACKGROUND Earlier initial antibiotic treatment for febrile neutropenia is associated with improved clinical outcomes. This study was conducted to evaluate the association of an emergency department (ED) intervention protocol with time to initial antibiotic treatment for febrile neutropenia patients. METHODS We conducted a cohort study of adult ED febrile neutropenia patients before and after implementation of an intervention protocol. Analyses included comparison of means and medians, Kaplan-Meier estimates, multivariable regression analyses, interrupted time-series analyses, and causal mediation analyses. The intervention protocol included specific triage and process-of-care actions to reduce the primary outcome of time to initial antibiotic treatment. RESULTS There were 69 patients in the 12-month preintervention period and 52 patients in the 8-month postintervention period. The mean (±SD) times to initial antibiotics were 197.6 (±85.4) min for the preintervention group and 97.7 (±51.0) min for the postintervention group (difference of 99.9 min with 95% confidence interval [CI] = 73.5 to 126.4, p < 0.001). The patients' probability for receiving initial antibiotics within 90 min was severalfold greater (adjusted risk ratio = 10.31, 95% CI = 4.99 to 21.30, p < 0.001) for the postintervention group versus preintervention group. ED length of stay, hospital length of stay, 30-day readmissions, and 30-day all-cause mortality were not different between the study groups. The association of the intervention protocol with time to initial antibiotics appeared to be mediated through times to treatment room placement, report of absolute neutrophil count, and initial antibiotic order. CONCLUSIONS The intervention protocol was associated with a significant reduction in time to initial antibiotics for ED patients with febrile neutropenia. This association appears to be facilitated through specific intermediate process-of-care variables. A larger multicenter study is needed to assess the potential effects of an ED febrile neutropenia protocol on patient-centered clinical outcomes and resource utilization.

Safety & efficacy of antibiotic de-escalation and discontinuation in high-risk haematological patients with febrile neutropenia: a single-centre experience. Open Forum Infect Dis 2021; 9:ofab624.

Abstract
Background There is currently no consensus on optimal duration of antibiotic treatment in febrile neutropenia. We report on the clinical impact of implementation of antibiotic de-escalation and discontinuation strategies based on the Fourth European Conference on Infections in Leukaemia (ECIL-4) recommendations in high-risk hematological patients. Methods We studied 446 admissions after introduction of an ECIL-4–based protocol (hereafter “ECIL-4 group”) in comparison to a historic cohort of 512 admissions. Primary clinical endpoints were the incidence of infectious complications including septic shock, infection-related intensive care unit (ICU) admission, and overall mortality. Secondary endpoints included the incidence of recurrent fever, bacteremia, and antibiotic consumption. Results Bacteremia occurred more frequently in the ECIL-4 group (46.9% [209/446] vs 30.5% [156/512]; P < .001), without an associated increase in septic shock (4.7% [21/446] vs 4.5% [23/512]; P = .878) or infection-related ICU admission (4.9% [22/446] vs 4.1% [21/512]; P = .424). Overall mortality was significantly lower in the ECIL-4 group (0.7% [3/446] vs 2.7% [14/512]; P = .016), resulting mainly from a decrease in infection-related mortality (0.4% [2/446] vs 1.8% [9/512]; P = .058). Antibiotic consumption was significantly reduced by a median of 2 days on antibiotic therapy (12 vs 14; P = .001) and 7 daily antibiotic doses (17 vs 24; P < .001) per admission period. Conclusions Our results support implementation of ECIL-4 recommendations to be both safe and effective based on real-world data in a large high-risk patient population. We found no increase in infectious complications and total antibiotic exposure was significantly reduced.

Comparative efficacy and safety of antipseudomonal β-lactams for pediatric febrile neutropenia: A systematic review and Bayesian network meta-analysis. Medicine (Baltimore) 2021; 100:e27266. [PMID: 34918626 PMCID: PMC8678002 DOI: 10.1097/md.0000000000027266] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Accepted: 08/31/2021] [Indexed: 01/05/2023] Open
Abstract
BACKGROUND Antipseudomonal β-lactams have been used for the treatment of febrile neutropenia (FN); however, the efficacy and safety of antipseudomonal β-lactams in pediatric patients remain unclear. The aim of this study was to comprehensively compare the efficacy and side effects of optional antipseudomonal β-lactams for pediatric FN. METHODS PubMed, Embase, Medline, and Cochrane Library were systematically searched from their inception to December 18, 2020. Eligible randomized controlled trials in which pediatric FN patients were treated with an empiric monotherapy of antipseudomonal β-lactams were selected. Data synthesis was performed using WinBUGS 14.0 software and meta packages implemented in R 3.6.2. Random-effects network meta-analysis was performed, and dichotomous data were pooled as odds ratios with 95% confidence intervals. The primary outcome was treatment success without modification; the secondary outcomes were adverse events (AEs), all-cause mortality, and new infections. The GRADE tool was used to assess the quality of the evidence. The protocol was registered with PROSPERO ID CRD42021226763. RESULTS Eighteen studies with 2517 patients were included. The results showed no statistically significant difference between the optional antipseudomonal β-lactams in the outcomes of treatment success without modification, all AEs, all-cause mortality, and new infections for pediatric FN. Based on the results of Bayesian rank probability, meropenem was ranked highest among all the treatment options with regard to treatment success without modification benefit; ceftazidime and meropenem were associated with a lower risk of AEs; cefoperazone/sulbactam and piperacillin/tazobactam were associated with a lower risk of mortality, and piperacillin/tazobactam and meropenem were associated with a lower risk of new infections. The quality of evidence was moderate. CONCLUSIONS Meropenem and piperacillin/tazobactam were found to be better with regard to treatment success without modification, with a comparable safety profile. Therefore, our findings support the use of meropenem and piperacillin/tazobactam as a treatment option for pediatric FN patients.

Abstract
Infections represent a significant cause of morbidity and mortality in cancer patients. Multiple factors related to the patient, tumor, and cancer therapy can affect the risk of infection in patients with solid tumors. A thorough understanding of such factors can aid in the identification of patients with substantial risk of infection, allowing medical practitioners to tailor therapy and apply prophylactic measures to avoid serious complications. The use of novel treatment modalities, including targeted therapy and immunotherapy, brings diagnostic and therapeutic challenges into the management of infections in cancer patients. A growing body of evidence suggests that antibiotic therapy can modulate both toxicity and antitumor response induced by chemotherapy, radiotherapy, and especially immunotherapy. This article provides a comprehensive review of potential risk factors for infections and therapeutic approaches for the most prevalent infections in patients with solid tumors, and discusses the potential effect of antibiotic therapy on toxicity and efficacy of cancer therapy.

Abstract
Adequate bone marrow recovery is a discharge requirement after admission for febrile neutropenia in oncology patients, without specific threshold in consensus guidelines. In January 2016, our institution implemented count recovery criteria of absolute neutrophil count ≥100 cells/μL and absolute phagocyte count ≥300 cells/μL compared with prior criteria of absolute neutrophil count ≥500 cells/μL. Retrospective analysis comparing pre (July 2013 to December 2015, N=68) and post (January 2016 to June 2018, N=30) groups showed no difference in readmissions (P>0.9), no patient deaths, and decreased average length of stay in the post group (P<0.0001). Updated count recovery criteria seem feasible and safe.

Cytomegalovirus reactivation in esophageal cancer patients receiving chemoradiotherapy: A retrospective analysis. Cancer Med 2021; 10:7525-7533. [PMID: 34514723 PMCID: PMC8559503 DOI: 10.1002/cam4.4269] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2021] [Revised: 08/13/2021] [Accepted: 09/01/2021] [Indexed: 12/18/2022] Open
Abstract
Background Although rare, cytomegalovirus (CMV) reactivation can be lethal in patients with cancer. However, the criteria for the prevention of cytomegalovirus reactivation during cancer treatment are unclear. This study aimed to identify factors associated with CMV reactivation in patients with esophageal cancer who were receiving chemoradiotherapy. Methods This retrospective study included esophageal cancer patients receiving definitive or palliative chemoradiotherapy during April 2013–March 2020. Patients with fever during chemoradiotherapy underwent a systemic work‐up to detect the primary focus of infection, and CMV antigenemia was assessed in cases of unidentifiable infection. Results Among 132 patients (80.3% male, median age 69 years [range, 39–86 years]), 124 received 5‐fluorouracil plus cisplatin and 8 received oxaliplatin–5‐fluorouracil–levofolinate chemotherapy. Overall, 19 patients had CMV reactivation, 37 had other infections, and 76 had no identified infection (groups 1, 2, and 3, respectively). Median minimum lymphocyte counts were 81.0/µl (interquartile range: 52.0–144.0/µl), 120.0/µl (81.0–162.5/µl), and 185.5/µl (120.5–328.0/µl) in groups 1, 2, and 3, respectively, with counts being significantly lower in groups 1 and 2 than in group 3 (p < 0.001). In multiple logistic regression analysis, the minimum lymphocyte count was associated with CMV reactivation (odds ratio 0.983, 95% confidence interval: 0.973–0.994, p = 0.002). Conclusion CMV reactivation is not rare in patients with esophageal cancer who were receiving chemoradiotherapy and is associated with the minimum lymphocyte counts. CMV reactivation should be considered during differential diagnosis for patients with a severe decline in lymphocyte counts when receiving chemoradiotherapy.

Granulocyte collection by polymorphonuclear cell-targeting apheresis with medium-molecular-weight hydroxyethyl starch. Int J Hematol 2021; 114:691-700. [PMID: 34453685 DOI: 10.1007/s12185-021-03207-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Revised: 08/06/2021] [Accepted: 08/18/2021] [Indexed: 11/27/2022]
Abstract
Granulocyte transfusion (GTX) is a therapeutic option for patients with prolonged neutropenia suffering from severe infections. Efficient granulocyte collection by apheresis from donors requires clear separation of granulocytes from red blood cells (RBCs), and infusion of high-molecular-weight (MW) hydroxyethyl starch (HES) facilitates RBC sedimentation. Recent research has shown that apheresis with medium-MW HES may prevent adverse effects of high-MW HES on donors, but the rationale for collection with medium-MW HES has yet to be evaluated. To validate the use of medium-MW HES, we first performed experiments with whole blood samples to determine how efficiently high-, medium- and low-MW HES separated granulocytes from RBCs, and found that medium-MW HES was just as efficient as high-MW HES. We also reviewed clinical data of granulocyte apheresis at our institution to evaluate granulocyte yields. Retrospective analysis of granulocyte collection revealed that apheresis with medium-MW HES yielded sufficient granulocytes for GTX and that donor anemia reduced collection efficiency. These results collectively may help us to establish a safer method for apheresis targeting polymorphonuclear granulocytes as an alternative to high-MW HES.

Abstract
PURPOSE Time to antibiotic administration (TTA) is a commonly used standard of care in pediatric cancer settings in high-income countries. Effective interventions to improve outcomes in cancer patients with febrile neutropenia (FN) often address timely and appropriate antibiotic administration. We assessed the effectiveness of a locally adapted multimodal strategy in decreasing TTA in a resource-constrained pediatric cancer center in Mexico. METHODS We conducted a prospective observational study between January 2014 and April 2019. A three-phase (phase I: execution, phase II: consolidation, phase III: sustainability) multimodal improvement strategy that combined system change, FN guideline development, education, auditing and monitoring, mentoring, and dissemination was implemented to decrease TTA in inpatient and ambulatory areas. Sustainability factors were measured by using a validated tool during phases I and III. RESULTS Our population included 105 children with cancer with 204 FN events. The baseline assessment revealed that only 50% of patients received antibiotics within 60 minutes of prescription (median time: inpatient, 75 minutes; ambulatory, 65 minutes). After implementing our improvement strategy, the percentage of patients receiving antibiotics within 60 minutes of prescription increased to 88%. We significantly decreased median TTA in both clinical areas during the three phases of the study. In phase III (sustainability), the median TTA was 40 minutes (P = .023) in the inpatient area and 30 minutes (P = .012) in the ambulatory area. The proportion of patients with sepsis decreased from 30% (baseline) to 5% (phase III) (P = .001). CONCLUSION Our results demonstrate that locally adapted multimodal interventions can reduce TTA in resource-constrained settings. Mentoring and dissemination were novel components of the multimodal strategy to improve FN-associated clinical outcomes. Improving local infrastructure, ongoing monitoring systems, and leadership engagement have been key factors to achieving sustainability during the 5-year period.

Abstract
Background Chemotherapy-induced neutropenia is commonly encountered in clinical practice. The management of neutropenia has been evolving from short-acting granulocyte colony-stimulating factors (G-CSFs) to long-acting G-CSFs. However, an evaluation of the safety and effectiveness of long-acting G-CSFs in clinical practice is still lacking. Methods This multicenter, non-interventional study was aimed at exploring the safety and effectiveness of mecapegfilgrastim in different cancer patients in China. All patients provided written informed consent prior to the study and were treated according to routine clinical practice. Different prophylactic strategies (primary or secondary prophylaxis) were also compared. Results This study included 638 patients from May 2019 to November 2020. More than half of the participants were breast cancer patients. The mean age of all the patients was 56 years. White blood cell increase (6.2%) was the most frequently reported adverse event (AE) possibly related to the study drug. No unexpected AEs were reported. Grade ≥3 neutropenia in chemotherapy treatment cycle 1 was reported in 36 (5.6%) patients. Incidence of grade ≥3 neutropenia in cycle 1 in the primary and secondary prophylaxis subgroups were of 4.3% and 9.2%, respectively. A decreasing trend of severe neutropenia incidence was observed from cycle 1 to cycle 4. Conclusions Mecapegfilgrastim was generally well tolerated, and no unexpected AEs were observed in this study. Primary administration of mecapegfilgrastim led to a lower incidence of neutropenia than did secondary administration. Continuous administration of mecapegfilgrastim could keep the incidence of neutropenia to a relatively low level.

Infection Complications after Lymphodepletion and Dosing of Chimeric Antigen Receptor T (CAR-T) Cell Therapy in Patients with Relapsed/Refractory Acute Lymphoblastic Leukemia or B Cell Non-Hodgkin Lymphoma. Cancers (Basel) 2021; 13:cancers13071684. [PMID: 33918340 PMCID: PMC8038233 DOI: 10.3390/cancers13071684] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2021] [Revised: 03/26/2021] [Accepted: 03/29/2021] [Indexed: 12/22/2022] Open
Abstract
Chimeric antigen receptor T (CAR-T) cell therapy has proven to be very effective in patients with relapsed/refractory acute lymphoblastic leukemia (ALL) and non-Hodgkin lymphoma (NHL). However, infections-related either due to lymphodepletion or the CAR-T cell therapy itself-can result in severe and potentially life-threatening complications, while side effects such as cytokine release syndrome (CRS) might complicate differential diagnosis. Sixty-seven dosings of CAR-T cells in sixty adult patients with NHL (85%) and ALL (15%) receiving CAR-T cell therapy were assessed for infectious complications. Almost two-thirds of patients (61%) developed fever following lymphodepletion and CAR-T cell dosing. Microbiological or radiological findings were observed in 25% of all cases (bacterial 12%, viral 5%, fungal 8%). Inpatient infections were associated with more lines of therapy and more severe CRS. However, overall serious complications were rare after CAR-T therapy, with one patient dying of infection. Pathogen detection after inpatient stay was infrequent and mostly occurred in the first 90 days after dosing. Infections in CAR-T cell treated patents are common. Fast and suitable identification and treatment are crucial in these heavily pretreated and immunocompromised patients. In most cases infectious complications are manageable. Nonetheless, standardized anti-infective prophylaxis and supportive therapy are mandatory to reduce morbidity and mortality in CAR-T cell therapy.

Abstract
Purpose The Multinational Association for Supportive Care in Cancer (MASCC) score is used to risk stratify outpatients with febrile neutropenia (FN). However, it is rarely used in hospital settings. We aimed to describe management, use of MASCC score, and outcomes among hospitalized patients with FN. Methods We conducted a retrospective cohort study of patients with cancer and FN. We collected patient demographics, cancer characteristics, microbiological profile, MASCC score, utilization of critical care therapies, documentation of goals of care (GOC), and inpatient deaths. Outcomes associated with low- (≥ 21) versus high-risk (< 21) MASCC scores are presented as absolute differences. Results Of 193 patients, few (2%, n = 3) had MASCC scores documented, but when calculated, 52% (n = 101) had a high-risk score (< 21). GOC were discussed in 12% (n = 24) of patients. Twenty one percent (n = 40) required intermediate/ICU level of care, and 12% (n = 23) died in the hospital. Those with a low-risk score were 33% less likely to require intermediate/ICU care (95% CI 23 to 44%) and 19% less likely to die in the hospital (95% CI 10% to 27%) compared to those with high-risk score. Conclusions MASCC score was rarely used for hospitalized patients with FN, but high-risk score was associated with worse outcomes. Education efforts to incorporate MASCC score into the workflow may help identify patients at high risk for complications and help clinicians admit these patients to a higher level of care (e.g., intermediate/ICU care) or guide them to initiate earlier GOC discussions.

Abstract
Allogeneic hematopoietic stem cell transplantation (HCT) is a complex therapeutic procedure causing significant morbidity and mortality, including the gastrointestinal tract. Early diagnosis and treatment of HCT-associated complications are, therefore, of utmost importance to improve overall HCT outcome. Sonography can be a powerful diagnostic tool and is easily accessible at the bedside of HCT patients. In the hands of a sonography-experienced physician, it allows for instant diagnosis and can also rule out several important transplant-associated complications. Here we review available evidence on the diagnostic and clinical value of ultrasound prior, during and after HCT.

Abstract
OBJECTIVE: This study aims to compare the frequency of respiratory viruses using real-time and multiplex polymerase chain reaction technology and nasopharyngeal swabs taken during exacerbation of patients aged 0–18 years followed for febrile neutropenia (FN) with non-FN children. METHODS: This prospective study included a total of 40 patients with FN and malignancies followed at Eskisehir Osmangazi University, Department of Pediatric Hematology and Oncology. The control group (n=76) consisted of age-matched patients with upper respiratory tract infections (URTIs) or lower respiratory tract infections (LRTIs) who were admitted to the emergency service due to fever. RESULTS: Viral agents were detected in 16 of 53 FN attacks (30.1%). The most commonly isolated viruses were coronavirus (23.7%, n=9), influenza B (18.4%, n=7), and adenovirus (18.4%, n=7). Of 76 children diagnosed with URTI with fever (52.6%) had viral agents, and only 28 of them had a single agent. The most commonly isolated virus was adenovirus (28.6%, n=14). Viral factors were found in 32 of 42 patients (76.1%) patients diagnosed with LRTI, while respiratory syncytial virus was the most common virus in 27 patients (21.7%, n=5). CONCLUSION: Our study results show that viral agents play an important role in the etiology of FN. This is the first study to show that viral agents play an important role in the etiology of this disease and viral factors in non-neutropenic febrile children at the same time period by detecting respiratory viruses in 30% of FN cases. More similar studies provide antiviral therapy in selected patients, as well as these studies lead to reduce the use of antimicrobial agents or allow more selective use of antibiotics and/or the earlier discontinuation of these antibiotics in febrile neutropenic children who have been shown to have viral cause of respiratory tract infection based on clinical and microbiological/molecular diagnostic criteria.

Abstract
BACKGROUND The role of urine studies in the detection of urinary tract infection (UTI) in febrile neutropenic patients with urinary symptoms (having a urinary catheter or having a positive urine analysis) is inarguable. However, the evidence is scarce regarding the indication for urine studies in asymptomatic (i.e., without urinary symptoms) patients with febrile neutropenia (FN) presenting to the emergency department (ED). The aim of this study is to evaluate the need for obtaining urine studies in asymptomatic febrile neutropenic patients. METHODS This was a retrospective cohort study conducted on adult cancer patients who presented to the ED with FN and had no urinary symptoms. We included all ED presentations of eligible patients between January 2013 and September 2018. Student's t-test and Wilcoxon rank-sum test were used for continuous data, while Chi-square and Fisher's exact tests were used for categorical data. Participants were divided into two groups based on their urine culture (UC) results: negative and positive UCs. Two cut-offs were used for positive UC results: ≥105 cfu/mL and ≥104 cfu/mL. RESULTS We included 284 patients in our study. The age of our patient population was 48.5±18.5 years. More than two-thirds (68.7%) of patients had severe neutropenia, while only 3.9% and 9.9% of the patients had positive UCs at ≥105 cfu/mL and ≥104 cfu/mL, respectively. UCs were expectedly positive in most patients with urinalysis (UA) abnormalities. However, 27.3% and 32.1% of patients with positive UCs at ≥105 cfu/mL and ≥104 cfu/mL respectively had a normal UA. CONCLUSIONS In our study, the incidence of UTI in adult febrile neutropenic cancer patients who present to the ED without urinary symptoms is low. Consequently, routine urine testing may not be warranted in this population, as it adds unnecessary financial burdens on the patients and delays timely management.

Abstract
Background Few small sample size studies have reported lymphocyte count was prognostic for survival in small-cell lung cancer (SCLC). This study aimed to validate this finding, to build prediction model for overall survival (OS) and to study whether novel models that combine lymphocyte-related variables can predict OS more accurately than a conventional model using clinical factors alone in a large cohort of limited-stage SCLC patients. Methods This study enrolled 544 limited-stage SCLC patients receiving definitive chemo-radiation with pre-radiotherapy lymphocyte-related variables including absolute lymphocyte count (ALC), platelet-to-lymphocyte ratio (P/L ratio), neutrophil-to-lymphocyte ratio (N/L ratio), and lymphocyte-to-monocyte ratio (L/M ratio). The primary endpoint was OS. These patients were randomly divided into a training dataset (n=274) and a validation dataset (n=270). Multivariate survival models were built in the training dataset, and the performance of these models were further tested in the validation dataset using the concordance index (C-index). Results The median follow-up time was 36 months for all patients. In the training dataset, univariate analysis showed that ALC (P=0.020) and P/L ratio (P=0.023) were significantly correlated with OS, while L/M ratio (P=0.091) and N/L ratio (P=0.436) were not. Multivariate modeling demonstrated the significance of ALC (P=0.063) and P/L ratio (P=0.003), and the improvement for OS prediction in combined models with the addition of ALC (C-index =0.693) or P/L ratio (C-index =0.688) over the conventional model (C-index =0.679). The validation dataset analysis confirmed a modest improvement of C-index with the addition of ALC or P/L ratio. All these models showed reasonable discriminations and calibrations. Conclusions This study validated the significant value of pre-radiotherapy ALC and P/L ratio on OS in limited-stage SCLC. The combined model with ALC or P/L ratio showed additional OS prediction values than the conventional model with clinical factors alone.

Abstract
Importance Plinabulin is a novel, non-granulocyte colony-stimulating factor (GCSF) small molecule with both anticancer and neutropenia-prevention effects. Objective To assess the efficacy and safety of plinabulin compared with pegfilgrastim for the prevention of chemotherapy-induced neutropenia following docetaxel chemotherapy in patients with non-small lung cancer. Design, Setting, and Participants This was a randomized, open-label, phase 2 clinical trial of 4 treatment arms that was conducted in 19 cancer treatment centers in the United States, China, Russia, and Ukraine. Participants were adult patients with non-small cell lung cancer whose cancer had progressed after platinum-based chemotherapy. Data were collected from April 2017 through March 2018 and analyzed from August 2019 through February 2020. Interventions All patients received docetaxel 75 mg/m2 on day 1 and were randomly assigned to 1 of 3 doses of plinabulin (5, 10, or 20 mg/m2) on day 1 or to pegfilgrastim 6 mg on day 2. Patients were treated every 21 days for 4 chemotherapy cycles. Main Outcomes and Measures The primary end point was the determination of the recommended phase 3 dose of plinabulin based on the days of severe neutropenia during chemotherapy cycle 1. Daily complete blood cell counts and absolute neutrophil counts were drawn during times of anticipated neutropenia during cycle 1. Results Of the 55 patients randomized and evaluated, the mean (SD) age was 61.3 (10.2) years, and 38 (69.1%) were men. With each escalation of the plinabulin dose, the incidence of any grade of neutropenia decreased. There were no significant differences in mean (SD) days of severe neutropenia among those treated with pegfilgrastim (0.15 [0.38] days) when dosed at day 2 vs plinabulin 20 mg/m2 (0.36 [0.93] days; P = .76) when dosed at day 1, and no safety signals were detected. Conclusions and Relevance Single dose-per-cycle plinabulin has a similar neutropenia protection benefit as pegfilgrastim. Plinabulin 40 mg fixed dose, which is pharmacologically equivalent to 20 mg/m2, will be compared with pegfilgrastim 6 mg in the phase 3 portion of this trial. Noninferior days of severe neutropenia will be the primary end point, and bone pain reduction, thrombocytopenia reduction, and quality of life maintenance will be secondary end points. Trial Registration ClinicalTrials.gov Identifier: NCT03102606.

Abstract
BACKGROUND Caregivers of children with cancer can experience stress when seeking care in the emergency department (ED). We sought to assess how caregivers prepare for and manage a medical emergency that arises in the community setting. METHODS A qualitative evaluation of ED visit preparations taken by children with cancer and their caregivers using self-reported interactive toolkits. Eligible participants included children with cancer (age: 11 to 21 y) currently receiving therapy for cancer diagnosis with an ED visit (besides initial diagnosis) within the previous 2 months and caregivers of same. Participants received a paper toolkit, which were structured as experience maps with several generative activities. Toolkits were transcribed, thematically coded, and iteratively analyzed using NVivo 12.0 software. RESULTS A total of 25 toolkits were received (7 children, 18 caregivers), with about three quarters of participants living >1 hour from the treating institution. Several important common themes and areas for improvement emerged. Themes included struggles with decision-making regarding when and where to seek ED care, preparing to go to the ED, waiting during the ED visit, repetition of information to multiple providers, accessing of ports, and provider-to-provider and provider-to-caregiver/patient communication. CONCLUSIONS The information gained from this study has the potential to inform a tool to support this population in planning for and managing emergent medical issues. This tool has the potential to improve patient and caregiver satisfaction, patient-centered outcomes, and clinical outcomes.

Abstract
BACKGROUND Hematopoietic cell transplantation (HCT) outcomes, including infectious complications, change between centers and countries. Thus, the aim of this study was to report the incidence of infections and isolated pathogens among recipients of HCT and the association with mortality at a tertiary referral center in Mexico. METHODS Two hundred and eighty-two patients undergoing autologous or allogeneic HCT between January 2005 and December 2018 at the National Institute of Medical Sciences and Nutricion Salvador Zubiran were included. RESULTS In autologous HCT (n = 176), within the preengraftment and the early postengraftment, 130 (74%) and 31 (18%) recipients presented infections, respectively. Within the preengraftment, the early postengraftment, and the late postengraftment, 81 (76%), 34 (33%), and 58 (60%) allogeneic HCT recipients presented infections, respectively. Non-relapse mortality (NRM) as a result of infections occurred in 1 (0.6%) and 5 (5%) autologous and allogeneic HCT recipients, respectively. CONCLUSIONS Our results demonstrated that despite our limited resources, infections were not a significant burden for NRM among HCT recipients. More importantly, the isolation rates were higher than international studies, which could be explained by the existence of a specialized infectious diseases department and laboratory, which we consider key elements for the establishment of an HCT program worldwide.

Abstract
BACKGROUND Children with cancer experience a wide range of conditions that require urgent evaluation in the emergency department (ED), yet variation in admission rates is poorly documented. PROCEDURE We performed a retrospective cohort study using the Pediatric Health Information System of ED encounters by children with cancer between July 2012 and June 2015. We compared demographics for admitted versus discharged using univariate statistics, and calculated admission rates by hospital, diagnosis, day of the week, and weekend versus weekday. We assessed the degree of interhospital admission rates using the index of dispersion (ID). RESULTS Children with cancer had 60 054 ED encounters at 37 hospitals. Overall, 62.5% were admitted (range 43.2%-92.1%, ID 2.6) indicating overdispersed admission rates with high variability. Children with cancer that visited the ED for a primary diagnosis of fever experienced the largest amount of variability in admission with rates ranging from 10.4% to 74.1% (ID 8.1). Less variability existed among hospital admission rates for both neutropenia (range 60%-100%, ID 1.0) and febrile neutropenia (FN) (range 66.7%-100%, ID 0.83). Admission rates by day of the week did not demonstrate significant variability for any of the scenarios examined (overall P = 0.91). There were no differences by weekend versus weekday either (overall P = 0.52). CONCLUSION The percentage of children with cancer admitted through the ED varies widely by institution and diagnosis. Standardization of best practices for children with cancer admitted through the ED should be an area of continued improvement.

Abstract
Filgrastim prophylaxis, both primary and secondary, was rapidly incorporated into clinical practice in the 1990s. When pegfilgrastim became available in 2002, it quickly replaced filgrastim as the colony-stimulating factor (CSF) of choice for prophylaxis. Use of prophylaxis increased markedly in the first decade of this century and has stabilized during the present decade. Data concerning real-world CSF prophylactic practice patterns are limited but suggest that both primary and secondary prophylaxis are common, and that use is frequently inappropriate according to guidelines. The extent of inappropriate use is controversial, as are issues concerning the cost-effectiveness of prophylaxis versus no prophylaxis and the cost-effectiveness of primary prophylaxis versus secondary prophylaxis. Nevertheless, CSF prophylaxis is firmly established as a valuable adjunct to chemotherapy and will almost certainly continue to be widely used for the foreseeable future. In this article, we chronicle the use and impact of CSF prophylaxis in US patients receiving myelosuppressive chemotherapy for non-myeloid malignancies. We emphasize the interplay of expert opinion, clinical evidence, and economic factors in shaping the use of CSFs in clinical practice over time, and, with the recent introduction of new CSF agents and options, we aim to provide useful clinical and economic information for healthcare decision makers.

Abstract
Infectious complications represent one of the most common causes of morbidity and mortality in allogeneic hematopoietic cell transplant (HCT) recipients. Prophylactic and preemptive treatment strategies against bacterial, fungal, viral, and parasitic pathogens are routinely implemented during high-risk post-HCT periods at most transplant centers. The basic concepts and review of current guidelines of antibiotic prophylaxis and empirical/preemptive antibiotic treatment in allogeneic HCT recipients are reviewed in this article.

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 A phase II study to evaluate the efficacy, tolerability and pharmacokinetics of oral or intravenous vinorelbine (VRL) plus cisplatin (CDDP) in Chinese patients with non-small cell lung cancer (NSCLC). Methods One hundred and thirty-one patients were randomised to oral VRL 60 mg/m2 (arm A) or intravenous VRL 25 mg/m2 (arm B) on days 1 and 8, plus CDDP 80 mg/m2 on day 1 (both arms). VRL was increased to 80 mg/m2 (arm A) or 30 mg/m2 (arm B) in cycles 2-4 in the absence of toxicity. Primary efficacy endpoint was objective response rate (ORR). VRL pharmacokinetics was evaluated for possible drug-drug interactions with CDDP. Results ORR was 25.8% in arm A and 23.1% in arm B. Disease control rate was 72.7% in arm A, 72.3% in arm B. Median overall survival was 16.1 months in arm A and 19.0 months in arm B. Median progression-free survival was 4.6 months in arm A and 4.9 months in arm B. Forty-three point nine percent and 86.2% of patients had grade 3/4 neutropenia in arms A and B, respectively; incidence of febrile neutropenia was low (6.1% and 9.2%, respectively). Frequency of grade 3/4 non-haematological adverse events was also low. VRL pharmacokinetics was not affected by co-administration of CDDP. Conclusions Oral and intravenous VRL in combination with CDDP is effective and well-tolerated in Chinese patients with advanced NSCLC. VRL pharmacokinetics is unaffected by CDDP co-administration. Oral VRL could be an effective alternative to intravenous VRL as a first-line treatment for NSCLC, as it optimises treatment convenience while maintaining high efficacy.

Abstract
Fever in a neutropenic oncology patient requires rapid initiation of effective empiric antibiotics to prevent mortality. We evaluated the appropriateness of our current empiric antibiotic regimen by assessing local antibiotic-susceptibility patterns in our pediatric oncology patients, and comparing them to the general pediatric patterns in our hospital. All blood culture isolates from pediatric oncology patients were reviewed over a 3-year period. Gram-negative and Gram-positive organisms were reviewed separately, with antibiotic susceptibilities for all unique isolates evaluated, and antibiograms generated and compared with general pediatric patients via the Fisher exact test. A total of 84% of Gram negatives were susceptible to meropenem; all resistant organisms were Pseudomonas aeruginosa, with 50% meropenem susceptibility. A total of 91% of Gram negatives were susceptible to cefepime, including 90% of P. aeruginosa and 80% of Escherichia coli. In total, 96% of Gram positives were vancomycin-susceptible; the only resistant organism was a single enterococcal isolate. In comparison with the general pediatric population, significantly fewer pseudomonal isolates were sensitive to meropenem among the oncology population (50% vs. 89%, P=0.0034). As such, in our population, meropenem does not provide adequate monotherapy against Pseudomonas. Ongoing surveillance of antibiotic resistance in this high-risk population is warranted, to ensure appropriate empiric antibiotic usage.

Abstract
Aims: Acinetobacter baumannii has become an important nosocomial pathogen that causes invasive infections. We conducted a retrospective study to evaluate the risk factors for mortality due to A. baumannii bacteremia in children. Materials and Methods: We reviewed data from Seoul National University Children's Hospital from 2002 to 2013 for children with A. baumannii bacteremia, including age, gender, underlying disease, associated site of infection, duration of hospitalization, presence of neutropenia, and antibiotic susceptibility data. The outcome measures were the 7- and 30-day mortality rates. Results: Among 74 A. baumannii bacteremia cases, 35.1% were carbapenem nonsusceptible. Common comorbidities were malignancy or hematologic diseases (28.4%), followed by gastrointestinal/hepatobiliary diseases (21.6%). A total of 47.3% of patients had isolated bacteremia, and in 33.8% of patients, pneumonia accompanied bacteremia. The mortality rates were 18.9% at 7 days and 35.1% at 30 days. The significant associated factors for 30-day mortality were carbapenem nonsusceptibility (adjusted hazard ratio [aHR]: 1.28, 95% confidence interval [CI]: 1.10-11.82, p = 0.034), neutropenia (aHR: 1.68, 95% CI: 1.60-18.03, p = 0.007), and prior intensive care unit (ICU) admission (aHR: 1.15, 95% CI: 1.03-9.73, p = 0.045). The mortality rate among neutropenic patients with inappropriate empirical antibiotics was higher than that among patients with appropriate empirical antibiotics (90.1% vs. 33.3%, p = 0.031). Conclusions: We identified carbapenem nonsusceptibility, neutropenia, and prolonged ICU stay as independent risk factors for mortality due to A. baumannii bacteremia in children. An early administration of appropriate antibiotics should be enacted, especially in patients with neutropenia.

Abstract
The association between fever and neutropenia and the risk for life-threatening infections in patients receiving cytotoxic chemotherapy has been known for 50 years. Indeed, infectious complications have been a leading cause of morbidity and mortality in patients with cancer. This review chronicles the progress in defining and developing approaches to the management of fever and neutropenia through observational and controlled clinical trials done by single institutions, as well as by national and international collaborative groups. The resultant data have led to recommendations and guidelines from professional societies and frame the current principles of management. Recommendations include those guiding new treatment options (from monotherapy to oral antibiotic therapy) and use of prophylactic antimicrobial regimens in high-risk patients. Of note, risk factors have changed with the advent of hematopoietic cytokines (especially granulocyte colony-stimulating factor) in shortening the duration of neutropenia, as well as with the discovery of more targeted cancer treatments that do not result in cytotoxicity, although these are still the exception. Most guiding principles that were developed decades ago-about when to begin empirical treatment after a neutropenic patient becomes febrile, whether and how to modify the initial treatment regimen (especially in patients with protracted neutropenia), and how long to continue antimicrobial therapy-are still used today. This review describes how the treatment principles related to the management of fever and neutropenia have responded to changes in the patients at risk, the microbes responsible, and the tools for their treatment, while still being sustained over the arc of time.

Abstract
PURPOSE Mucormycosis is a rare opportunistic and aggressive deep fungal infection that predominantly affects immunocompromised patients, and its mortality rate has been reported as up to 80%. Typing of the infection is based mainly on clinical and anatomic presentations, with the most common being the rhinocerebral type. MATERIALS AND METHODS This report presents 3 patients with cancer who had successful treatment of mandibular mucormycosis. Chemotherapy was administered 13 to 30 days before diagnosis of the infection, resulting in neutropenia in all patients. Each case is thoroughly presented from initial admission through its diagnosis and treatment sequence. RESULTS Early surgical ablative treatment and antifungal treatment resulted in the resolution of infection in all patients. Absolute neutrophil count increased 7 to 8 days after surgical debridement. CONCLUSIONS Bringing patients to the post-neutropenic state tremendously increases their odds for survival.

Abstract
PURPOSE To determine if time to antibiotics (TTA) improves outcomes of hospital length of stay, admission to the intensive care unit, and 30-day mortality in adult patients with febrile neutropenia. METHODS This retrospective cohort study evaluated the impact of time to antibiotic, in the treatment of febrile neutropenia, on hospital length of stay, admission to the intensive care unit, and 30-day mortality. Cases included were patients 18 years or older hospitalized with febrile neutropenia from August 1, 2006 to July 31, 2016. To adjust for other characteristics associated with hospital length of stay, admission to the intensive care unit, and 30-day mortality, a multivariate analysis was performed. RESULTS A total of 3219 cases of febrile neutropenia were included. The median hospital length of stay was 7.0 days (IQR 4.1-13.3), rate of intensive care unit admission was 13.6%, and 30-day mortality was 6.6%. Multivariate analysis demonstrated time to antibiotics was not associated with hospital length of stay but was associated with admission to the intensive care unit admission and 30-day mortality. Delays in time to antibiotic of up to 3 hours did not impact outcomes. CONCLUSIONS A shorter time to antibiotic is important in treatment of febrile neutropenia; however, moderate delays in antibiotic administration did not impact outcomes. Further investigation is needed in order to determine if other indicators of infection, in addition to fever, or other supportive management, in addition to antibiotics, are indicated in the early identification and management of infection in patients with neutropenia.

Abstract
Background In patients with hematological malignancies, febrile neutropenia (FEN) is the most frequent complication and the most important cause of mortality. Various risk factors have been identified for severe infection in neutropenic patients. However, to the best of our knowledge, it is not defined whether there is a change in the risk of febrile neutropenia according to seasons. The first aim of study was to determine the difference in frequency of febrile neutropenic episodes (FNEs) according to months and seasons. The second aim was to document isolated pathogens, as well as demographical and clinical characteristics of patients. Methods In the study, 194 FNEs of 105 patients who have been followed with hematological malignancies between June 2013 and May 2014 were evaluated retrospectively. Results Although the number of FNEs increased in autumn, there was no significant difference in frequency of FNEs between months (p = 0.564) and seasons (p = 0.345). There was no isolated pathogen in 54.6% of FNEs. In 45.4% of 194 FNEs, pathogens were isolated. Of all pathogens, 50.4% were gram negative bacteria, 29.2% were gram positive bacteria, 13.3% were viruses, 5.3% were fungi, and 1.8% were parasites. Conclusıons The frequency of FEN does not change according to months or seasons. Also, the relative proportions of different pathogens in the cause of FEN do not vary according to seasons.

Abstract
BACKGROUND People with cancer with febrile neutropenia are at risk of severe infections and mortality and are thus treated empirically with broad-spectrum antibiotic therapy. However, the recommended duration of antibiotic therapy differs across guidelines. OBJECTIVES To assess the safety of protocol-guided discontinuation of antibiotics regardless of neutrophil count, compared to continuation of antibiotics until neutropenia resolution in people with cancer with fever and neutropenia, in terms of mortality and morbidity. To assess the emergence of resistant bacteria in people with cancer treated with short courses of antibiotic therapy compared with people with cancer treated until resolution of neutropenia. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 10) in the Cochrane Library, MEDLINE, Embase, and LILACS up to 1 October 2018. We searched the metaRegister of Controlled Trials and the US National Institutes of Health Ongoing Trials Register ClinicalTrials.gov for ongoing and unpublished trials. We reviewed the references of all identified studies for additional trials and handsearched conference proceedings of international infectious diseases and oncology and haematology conferences. SELECTION CRITERIA We included randomised controlled trials (RCTs) that compared a short antibiotic therapy course in which discontinuation of antibiotics was guided by protocols regardless of the neutrophil count to a long course in which antibiotics were continued until neutropenia resolution in people with cancer with febrile neutropenia. The primary outcome was 30-day or end of follow-up all-cause mortality. DATA COLLECTION AND ANALYSIS Two review authors independently reviewed all studies for eligibility, extracted data, and assessed risk of bias for all included trials. We calculated risk ratios (RRs) with 95% confidence intervals (CIs) whenever possible. For dichotomous outcomes with zero events in both arms of the trials, we conducted meta-analysis of risk differences (RDs) as well. For continuous outcomes, we extracted means with standard deviations (SD) from the studies and computed mean difference (MD) and 95% CI. If no substantial clinical heterogeneity was found, trials were pooled using the Mantel-Haenszel fixed-effect model. MAIN RESULTS We included eight RCTs comprising a total of 662 distinct febrile neutropenia episodes. The studies included adults and children, and had variable design and criteria for discontinuation of antibiotics in both study arms. All included studies but two were performed before the year 2000. All studies included people with cancer with fever of unknown origin and excluded people with microbiological documented infections.We found no significant difference between the short-antibiotic therapy arm and the long-antibiotic therapy arm for all-cause mortality (RR 1.38, 95% CI 0.73 to 2.62; RD 0.02, 95% CI -0.02 to 0.05; low-certainty evidence). We downgraded the certainty of the evidence to low due to imprecision and high risk of selection bias. The number of fever days was significantly lower for people in the short-antibiotic treatment arm compared to the long-antibiotic treatment arm (mean difference -0.64, 95% CI -0.96 to -0.32; I² = 30%). In all studies, total antibiotic days were fewer in the intervention arm by three to seven days compared to the long antibiotic therapy. We found no significant differences in the rates of clinical failure (RR 1.23, 95% CI 0.85 to 1.77; very low-certainty evidence). We downgraded the certainty of the evidence for clinical failure due to variable and inconsistent definitions of clinical failure across studies, possible selection bias, and wide confidence intervals. There was no significant difference in the incidence of bacteraemia occurring after randomisation (RR 1.56, 95% CI 0.91 to 2.66; very low-certainty evidence), while the incidence of any documented infections was significantly higher in the short-antibiotic therapy arm (RR 1.67, 95% CI 1.08 to 2.57). There was no significant difference in the incidence of invasive fungal infections (RR 0.86, 95% CI 0.32 to 2.31) and development of antibiotic resistance (RR 1.49, 95% CI 0.62 to 3.61). The data on hospital stay were too sparse to permit any meaningful conclusions. AUTHORS' CONCLUSIONS We could make no strong conclusions on the safety of antibiotic discontinuation before neutropenia resolution among people with cancer with febrile neutropenia based on the existing evidence and its low certainty. Results of microbiological outcomes favouring long antibiotic therapy may be misleading due to lower culture positivity rates under antibiotic therapy and not true differences in infection rates. Well-designed, adequately powered RCTs are required that address this issue in the era of rising antibiotic resistance.

Abstract
Benign neutropenia, observed in different ethnic groups, is the most common form of neutropenia worldwide. A specific single nucleotide polymorphism, rs2814778, located at the promoter of the ACKR1 (previously termed DARC) gene, which disrupts a binding site for the GATA1 erythroid transcription factor, resulting in a ACKR1-null phenotype, was found to serve as a predictor of low white blood cell and neutrophil counts in African-Americans and Yemenite Jews. Individuals with benign neutropenia due to the ACKR1-null allele have been found to have an increased susceptibility to human immunodeficiency virus infection and, on the other hand, a protective effect against malaria. The associated protective effect may explain the spread of the ACKR1-null allele by natural selection. The reviewed relationships between ACKR1 polymorphism and various pathological states may have important clinical implications to individuals with and without benign neutropenia. Potential mechanisms for ACKR1 (previously termed DARC) modulation during neutrophil recruitment to inflammation, and chemokine bioavailability in the circulation and in local tissue are reviewed and discussed.

Abstract
Objectives: To determine effective risk factors on mortality in febrile neutropenic cases with hematologic malignancy. Patients with hematologic diseases are more prone to infections and those are frequent causes of mortality. Methods: This retrospective study was performed using data of 164 febrile neutropenic cases with hematologic malignancies who were followed up in a hematology clinic of a tertiary health care center between 2011-2015. The relationship between descriptive and clinical parameters rates and rates of mortality on the 7th and the 21st days were investigated. Results: Patients with absolute neutrophil count<100/mm3, duration of neutropenia longer than 7 days, pneumonia or gastrointestinal foci of infection, central catheterization (p=0.025), isolation of Gram (-) bacteria in culture, carbapenem resistance, septic shock, and bacterial growth during intravenous administration of antibiotic treatment were under more risk for mortality on both the 7th and the 21st days. The final multivariate logistic regression results showed that pneumonia (p<0.0001), septic shock (p=0.004) and isolation of Gram-negative bacteria (p=0.032) were statistically significant risk factors. Conclusion: Early diagnosis and appropriate treatment of serious infections, which are important causes of morbidity and mortality, are crucial in patients with febrile neutropenia. Thus, each center should closely follow up causes of infection and establish their empirical antibiotherapy protocols to accomplish better results in the management of febrile neutropenia.

Abstract
Los receptores de los diferentes tipos de trasplante presentan un riesgo elevado de infección. En los trasplantados de precursores hematopoyéticos predominan las infecciones nosocomiales. Durante el periodo posprendimiento temprano (30-100 días tras la infusión del trasplante), la incidencia de infección es más elevada en pacientes con enfermedad de injerto contra huésped. En el pulmón pueden aparecer lesiones nodulares por infección fúngica invasora o bien un patón difuso habitualmente secundario a infección vírica o a neumonía por P. jirovecii. Después de los primeros 100 días persiste un moderado riesgo de infección por microorganismos convencionales y oportunistas, como la infección tardía por CMV. Los avances en las técnicas quirúrgicas y el empleo de calcineurínicos han reducido la mortalidad por infecciones en trasplantados de órgano sólido. Durante el primer mes, son frecuentes las infecciones nosocomiales; entre el primer y sexto mes son más frecuentes las infecciones oportunistas dependientes de la inmunidad celular y a partir de sexto mes el riesgo baja y predominan las infecciones comunitarias semejantes a las de los pacientes inmunocompetentes.
