Yang Z, Leng K, Shi G. Causes of death among patients with hepatocellular carcinoma in United States from 2000 to 2018. Cancer Med 2023. [PMID: 37083308 DOI: 10.1002/cam4.5986] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Revised: 03/21/2023] [Accepted: 04/09/2023] [Indexed: 04/22/2023] Open
Abstract
BACKGROUND The gains in survival outcomes of US patients with hepatocellular carcinoma (HCC) have come at the expense of developing non-cancer-related morbidities, such as cardiovascular diseases (CVDs) and infections. However, population-based data on causes of death (CODs) in patients with HCC are scarce. METHODS A cancer registry database in the United States was used to analyze the CODs among patients with HCC. Death cause distribution and standardized mortality ratios were calculated to quantify the disease-specific death burden. RESULTS A total of 40,094 patients with a histological diagnosis of HCC were identified from the SEER-18 database between 2000 and 2018, of which 30,796 (76.8%) died during the follow-up period. The majority of these deaths (25,153, 81.7%) occurred within 2 years after diagnosis, 13.2% (4075) occurred within 2-5 years, and 5.1% (1568) occurred after 5 years. All age groups had a lower burden of female deaths than of male deaths during the study period. With respect to CODs, 23,824 (77.4%), 2289 (7.4%), and 4683 (15.2%) were due to HCC, other cancers, and non-cancer causes, respectively. Non-cancer-related deaths were more common among older patients and those with longer latency periods since diagnosis. The major causes of non-cancer-related deaths are other infectious and parasitic diseases, including HIV and CVDs. CONCLUSIONS CODs during HCC survivorship varied, and a growing number of survivors tended to die from causes other than HCC, with an increasing latency period since diagnosis. Comprehensive analyses of mortality patterns and temporal trends could underpin strategies to reduce these risks.

Shorter antibiotic courses in the immunocompromised: the impossible dream? Clin Microbiol Infect 2023; 29:143-149. [PMID: 35988852 DOI: 10.1016/j.cmi.2022.08.007] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Revised: 08/08/2022] [Accepted: 08/09/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND A growing number of studies have demonstrated similar outcomes with shorter courses of antibiotics for bacterial infections. Immunocompromised patients are frequently excluded from these studies despite anticipated benefits associated with shortening antibiotic courses (including lower risks of antibiotic toxicity, Clostridioides difficile infection, drug-resistant pathogens, and microbiome alterations). OBJECTIVES To critically review the literature that assesses shorter antibiotic courses in immunocompromised patients, specifically among solid organ transplant recipients and neutropenic fever (NF) syndromes among patients on antineoplastic chemotherapy and undergoing haematopoietic cell transplant. SOURCES References were identified through searches of PubMed, Embase, MEDLINE, and clinical guidelines documents. CONTENT Among organ transplant recipients, the majority of studies assessing outcomes associated with shorter antibiotic courses have been retrospective but have demonstrated similar rates of clinically relevant endpoints. Patients with high- and low-risk NF have been well-studied, including enrolment in randomized studies, albeit with heterogeneous patient populations and outcomes assessed. Clinical improvement-guided adoption of shorter courses has been associated with fewer antibiotic days and similar rates of fever recurrence and mortality. IMPLICATIONS Similar to studies demonstrating efficacy in immunocompetent patients, shorter antibiotic courses should be considered for immunocompromised hosts with presumed bacterial infections. Organ recipients and patients with NF syndromes should be prioritized for study in randomized controlled clinical trials assessing shorter course therapy.

MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58091157. [PMID: 36143836 PMCID: PMC9501244 DOI: 10.3390/medicina58091157] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Revised: 08/10/2022] [Accepted: 08/23/2022] [Indexed: 11/16/2022]
Abstract
Background and Objectives: Neutropenic fever (NF) is a major cause of mortality and morbidity in patients undergoing hematopoietic stem cell transplantation (HSCT). To date, no study has discussed the relationship of fever days in HSCT with the time between recording the fever and administering antibiotics. This study aimed to examine the association between fever days in HSCT and the time interval between recording the fever and intravenous (IV) antibiotics to the febrile neutropenia patient. Materials and Methods: A total of 22 patients who developed NF after HSCT in one hospital were analyzed. Patients who received IV antibiotics injection within 30 min were categorized in group A and those who received the injection after 30 min were categorized in group B. Fever was defined by an attack with an oral temperature of 38.3 °C. Patients’ characteristics and possible risk factors were recorded and analyzed. Results: Groups A and B had 14 and 8 patients, respectively. Patient characteristics, including age, diagnosis, sex, and antibiotics level, were similar between the two groups. The median duration of fever days was 1.5 (range, 1−5) in group A and 6.5 (range, 1−14) in group B (p = 0.003). Multivariant analysis of possible independent impact factors of “fever days in HSCT” was performed. The odds ratio of “antibiotics given time” was 4.00 (95% confidence interval [CI] = 2.26 to 7.22, p = 0.001). The “antibiotics level” did not affect the NF period (odds ratio = −0.80, 95% CI = −2.40 to 1.07, p = 0.453). Conclusions: Rapid IV administration of antibiotics (<30 min after fever attack) can reduce the fever days in patients undergoing HSCT.

Abstract
Simple Summary The transfer of a normal intestinal microbial community from healthy donors by way of their fecal material into patients with various diseases is an emerging therapeutic approach, particularly to treat patients with recurrent or refractory C. difficile infections (CDI). This approach, called fecal microbiota transplant (FMT), is increasingly being applied to patients with hematologic and oncologic diseases to treat recurrent CDI, modulate treatment-related complications, and improve cancer treatment outcome. In this review paper, we discussed the principles and methods of FMT. We examined the results obtained thus far from its use in hematologic and oncologic patients. We also propose novel uses for the therapeutic approach and appraised the challenges associated with its use, especially in this group of patients. Abstract Understanding of the importance of the normal intestinal microbial community in regulating microbial homeostasis, host metabolism, adaptive immune responses, and gut barrier functions has opened up the possibility of manipulating the microbial composition to modulate the activity of various intestinal and systemic diseases using fecal microbiota transplant (FMT). It is therefore not surprising that use of FMT, especially for treating relapsed/refractory Clostridioides difficile infections (CDI), has increased over the last decade. Due to the complexity associated with and treatment for these diseases, patients with hematologic and oncologic diseases are particularly susceptible to complications related to altered intestinal microbial composition. Therefore, they are an ideal population for exploring FMT as a therapeutic approach. However, there are inherent factors presenting as obstacles for the use of FMT in these patients. In this review paper, we discussed the principles and biologic effects of FMT, examined the factors rendering patients with hematologic and oncologic conditions to increased risks for relapsed/refractory CDI, explored ongoing FMT studies, and proposed novel uses for FMT in these groups of patients. Finally, we also addressed the challenges of applying FMT to these groups of patients and proposed ways to overcome these challenges.

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. [PMID: 35146042 PMCID: PMC8826378 DOI: 10.1093/ofid/ofab624] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Accepted: 12/07/2021] [Indexed: 11/26/2022] Open
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.

Abstract
Cancer treatment options have evolved to include immunotherapy and targeted therapy, in addition to traditional chemoradiation. Chemoradiation places the patient at a higher risk of infection through a myelosuppressive effect. High clinical suspicion and early use of antimicrobials play a major role in decreasing any associated morbidity and mortality. This has led to a widespread use of antimicrobials in cancer patients. Antimicrobial use, however, does not come without its perils. Dysbiosis caused by antimicrobial use affects responses to chemotherapeutic agents and is prognostic in the development and severity of certain cancer treatment-related complications such as graft-versus-host disease and Clostridioides difficile infections. Studies have also demonstrated that an intact gut microbiota is essential in the anticancer immune response. Antimicrobial use can therefore modulate responses and outcomes with immunotherapy targeting immune checkpoints. In this review, we highlight the perils associated with antimicrobial use during cancer therapy and the importance of a more judicious approach. We discuss the nature of the pathologic changes in the gut microbiota resulting from antimicrobial use. We explore the effect these changes have on responses and outcomes to different cancer treatment modalities including chemotherapy and immunotherapy, as well as potential adverse clinical consequences in the setting of stem cell transplant.

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
Introduction Cancer patients are prone to infections, but the mortality of fatal infections remains unclear. Understanding the patterns of fatal infections in patients with cancer is imperative. In this study, we report the characteristics, incidence, and predictive risk factors of fatal infections among a population-based cancer cohort. Methods A total of 8,471,051 patients diagnosed with cancer between 1975 and 2016 were retrospectively identified from the Surveillance, Epidemiology, and End Results (SEER) program. The primary outcome was dying from fatal infections. Mortality rates and standardized mortality ratios (SMRs) adjusted for age, sex, race, and calendar year were calculated to characterize the relative risks of dying from fatal infections and to compare with the general population. Furthermore, cumulative mortality rates and the Cox regression models were applied to identify predictive risk factors of fatal infections. Results In cancer patients, the mortality rate of fatal infections was 260.1/100,000 person-years, nearly three times that of the general population [SMR, 2.92; 95% (confidence interval) CI 2.91–2.94]. Notably, a decreasing trend in mortality rate of fatal infections was observed in recent decades. SMRs of fatal infections were highest in Kaposi sarcoma (SMR, 162.2; 95% CI 159.4–165.1), liver cancer (SMR, 30.9; 95% CI 30.0–31.8), acute lymphocytic leukemia (SMR, 19.1; 95% CI 17.0–21.4), and acute myeloid leukemia (SMR, 13.3; 95% CI 12.4–14.3). Patients aged between 20 and 39 years old exhibited a higher cumulative mortality rate in the first few years after cancer diagnosis, whereas the cumulative mortality rate of those > 80 years old was rapidly increasing and became the highest approximately 3 years post-cancer diagnosis. Predictive risk factors of dying from fatal infections in cancer patients were the age of 20–39 or > 80 years, male sex, black race, diagnosed with cancer before 2000, unmarried status, advanced cancer stage, and not receiving surgery and radiotherapy, but receiving chemotherapy. Conclusion Cancer patients were at high risks of dying from infectious diseases. Certain groups of cancer patients, including those aged between 20 and 39 or > 80 years, as well as those receiving chemotherapy, should be sensitized to the risk of fatal infections.

Abstract
For better management of patients with febrile neutropenia, our study investigated the epidemiologic, microbiologic, and clinical characteristics of adult inpatients with febrile neutropenia and their mortality-associated factors. To this end, we carried out a prospective, observational, multicenter study in 28 Argentinian hospitals between 2007 and 2012. We included 515 episodes of febrile neutropenia from 346 patients, median age 49 years. Neutropenia followed chemotherapy in 77% of cases, half of the cases due to hematological malignancies. Most episodes were classified as high-risk according to MASCC criteria, and 53.6% of patients were already hospitalized at the onset of febrile neutropenia. Bloodstream infections were detected in 14% episodes; whereas an infectious source of fever was identified in 80% of cases. Mortality rate achieved to 14.95%. The binary regression analysis showed that persistence of fever at day 7, or neutropenia at day 14, dehydration and tachycardia at the onset of febrile neutropenia as well as prior infections were significantly associated with mortality. In addition to expanding our current knowledge on the features of adult patients with febrile neutropenia, present findings provide useful information for better management of them in Argentina, given the appropriate representativeness of centers participating in the study.

Abstract
Cancer consists of heterogeneous multiple cell subpopulation which at a later stage develop resistant phenotypes, which include resistance to pro-apoptotic stimuli and/or cytotoxic resistance to anticancer compounds. The property of cancerous cells to affect almost any part of the body categorizes cancer to many anatomic and molecular subtypes, each requiring a particular therapeutic intervention. As several modalities are hindered in a variety of cancers and as the cancer cells accrue varied types of oncogenic mutations during their progression the most likely benefit will be obtained by a combination of therapeutic agents that might address the diverse hallmarks of cancer. Natural compounds are the backbone of cancer therapeutics owing to their property of affecting the DNA impairment and restoration mechanisms and also the gene expression modulated via several epigenetic molecular mechanisms. Bioactive peptides isolated from flora and fauna have transformed the arena of antitumour therapy and prompt progress in preclinical studies is promising. The difficulties in creating ACP rest in improving its delivery to the tumour site and it also must maintain a low toxicity profile. The substantial production costs, low selectivity and proteolytic stability of some ACP are some of the factors hindering the progress of peptide drug development. Recently, several publications have tried to edify the field with the idea of using peptides as adjuvants with established drugs for antineoplastic use. This review focuses on peptides from natural sources that precisely target tumour cells and subsequently serve as anticancer agents that are less toxic to normal tissues.

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
Febrile neutropenia (FN) is a common dose-limiting toxicity of chemotherapy, with a profound impact on the evolution of patients with cancer, due to the potential development of serious complications, mortality, delays, and decrease in treatment intensity. This article seeks to present an updated clinical guideline, with recommendations regarding the diagnosis, prevention, and treatment of febrile neutropenia in adults with solid tumors. The aspects covered include how to properly approach the risk of microbial resistances, epidemiological aspects, considerations about the initial empirical approach adapted to the risk, special situations, and prevention of complications. A decision-making algorithm is included for use in the emergency department based on a new, validated tool, the Clinical Index of Stable Febrile Neutropenia, which can be used in patients with solid tumors who appear stable in the initial phase of neutropenic infections, and can help detect those at high risk for complications in whom early discharge must be avoided.

Abstract
INTRODUCTION Infections represent a major complication of hematological malignancies. C-reactive protein (CRP) and procalcitonin (PCT) have been used as diagnostic biomarkers of infections, but do not produce definitive findings. Recently, a new biomarker, presepsin, has been used as a diagnostic tool for detecting infections in the fields of emergency and neonatal medicine. However, the usefulness of presepsin for identifying infections in patients with hematological malignancies, including those who develop febrile neutropenia, remains unclear. METHODS In this study, we retrospectively analyzed the utility of PCT, presepsin, and CRP as biomarkers of infections during 49 febrile episodes that occurred in 28 patients with hematological malignancies. RESULTS The levels of PCT, but not those of CRP or presepsin, were significantly higher in the infection group than in the uninfected group (P<.03), indicating that PCT might be a more sensitive biomarker of infections. No differences in presepsin levels were detected between the patients with and without neutropenia, or between the infected and uninfected patients with neutropenia, indicating that presepsin might have less diagnostic value in patients with neutropenia. CONCLUSIONS We conclude that PCT might provide additional information and could be used in combination with other biomarkers to detect infections in patients with hematological malignancies.

Abstract
BACKGROUND In 2012, new international guidelines for children with chemotherapy-induced febrile neutropenia (FN) were issued, recommending reduced-intensity management strategy based on stratification of infectious risks. Some studies have highlighted practice disparities in different countries and within the same country. Our aim was to assess the current management strategies for the treatment of chemotherapy-induced FN in children in France. PROCEDURE This survey of all French pediatric oncology-hematology reference centers (n = 30) in late 2012 and early 2013 sent a standardized questionnaire to each center inquiring about their definition of an FN episode, its initial empiric treatment and ongoing management, use of management stratified by risk, and any criteria used for the risk assessment. Each center's management protocol was also analyzed. RESULTS All French reference centers participated in this survey, completing 88% of the questionnaire items. Definitions of both fever and neutropenia varied between centers. Ten centers used a risk-stratification strategy for initial management. In all, 42 probabilistic first-line antibiotic treatments were identified. After 48 hr of apyrexia, 17 units applied different forms of step-down therapy. CONCLUSIONS Most French centers already offered some form of reduced-intensity or step-down therapy, although they differed substantially in their management of FN episodes. Risk stratification with validated tools is essential to facilitate the implementation of the international recommendations, which would ultimately help to standardize practices in France.

Abstract
The European Hematology Association (EHA) Roadmap for European Hematology Research highlights major achievements in diagnosis and treatment of blood disorders and identifies the greatest unmet clinical and scientific needs in those areas to enable better funded, more focused European hematology research. Initiated by the EHA, around 300 experts contributed to the consensus document, which will help European policy makers, research funders, research organizations, researchers, and patient groups make better informed decisions on hematology research. It also aims to raise public awareness of the burden of blood disorders on European society, which purely in economic terms is estimated at €23 billion per year, a level of cost that is not matched in current European hematology research funding. In recent decades, hematology research has improved our fundamental understanding of the biology of blood disorders, and has improved diagnostics and treatments, sometimes in revolutionary ways. This progress highlights the potential of focused basic research programs such as this EHA Roadmap.The EHA Roadmap identifies nine 'sections' in hematology: normal hematopoiesis, malignant lymphoid and myeloid diseases, anemias and related diseases, platelet disorders, blood coagulation and hemostatic disorders, transfusion medicine, infections in hematology, and hematopoietic stem cell transplantation. These sections span 60 smaller groups of diseases or disorders.The EHA Roadmap identifies priorities and needs across the field of hematology, including those to develop targeted therapies based on genomic profiling and chemical biology, to eradicate minimal residual malignant disease, and to develop cellular immunotherapies, combination treatments, gene therapies, hematopoietic stem cell treatments, and treatments that are better tolerated by elderly patients.

Abstract
BACKGROUND Monotherapy is recommended as the first choice for initial empirical therapy of febrile neutropenia, but local epidemiological and antibiotic susceptibility data are now considered pivotal to design a correct management strategy. AIM To evaluate the proportion of Gram-negative rods isolated in bloodstream infections in children with cancer resistant to antibiotics recommended for this indication. MATERIALS & METHODS The in vitro susceptibility to ceftazidime, piperacillin-tazobactam, meropenem and amikacin of Gram-negatives isolated in bacteremic episodes in children with cancer followed at the Istituto "Giannina Gaslini", Genoa, Italy in the period of 2001-2013 was retrospectively analyzed using the definitions recommended by EUCAST in 2014. Data were analyzed for any single drug and to the combination of amikacin with each β-lactam. The combination was considered effective in absence of concomitant resistance to both drugs, and not evaluated by means of in vitro analysis of antibiotic combinations (e.g., checkerboard). RESULTS A total of 263 strains were evaluated: 27% were resistant to piperacillin-tazobactam, 23% to ceftazidime, 12% to meropenem and 13% to amikacin. Concomitant resistance to β-lactam and amikacin was detected in 6% of strains for piperacillin-tazobactam, 5% for ceftazidime and 5% for meropenem. During the study period there was a nonsignificant increase in the proportions of strains resistant to β-lactams indicated for monotherapy, and also increase in the resistance to combined therapies. CONCLUSION in an era of increasing resistance to antibiotics guideline-recommended monotherapy could be not appropriate for initial empirical therapy of febrile neutropenia. Strict local survey on etiology and antibiotic susceptibility is mandatory for a correct management of this complication in cancer patients.

Abstract
The prevention and treatment of sepsis in the immunocompromised host present a challenging array of diagnostic and management issues. The neutropenic patient has a primary defect in innate immune responses and is susceptible to conventional and opportunistic pathogens. The solid organ transplant patient has a primary defect in adaptive immunity and is susceptible to a myriad of pathogens that require an effective cellular immune response. Risk for infections in organ transplant recipients is further complicated by mechanical, vascular, and rejection of the transplanted organ itself. The immune suppressed state can modify the cardinal signs of inflammation, making accurate and rapid diagnosis of infection and sepsis difficult. Empiric antimicrobial agents can be lifesaving in these patients, but managing therapy in an era of progressive antibiotic resistance has become a real issue. This review discusses the challenges faced when treating severe infections in these high-risk patients.

Abstract
BACKGROUND Fever occurring in a neutropenic patient remains a common life-threatening complication of cancer chemotherapy. The common practice is to admit the patient to hospital and treat him or her empirically with intravenous broad-spectrum antibiotics. Oral therapy could be an alternative approach for selected patients. OBJECTIVES To compare the efficacy of oral antibiotics versus intravenous (IV) antibiotic therapy in febrile neutropenic cancer patients. SEARCH METHODS The Cochrane Central Register of Controlled Trials (CENTRAL) (2013, Issue 1) in The Cochrane Library, MEDLINE (1966 to January week 4, 2013), EMBASE (1980 to 2013 week 4) and LILACS (1982 to 2007). We searched several databases for ongoing trials. We checked the conference proceedings of the Interscience Conference of Antimicrobial Agents and Chemotherapy (ICAAC) (1995 to 2007), and all references of included studies and major reviews were scanned. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing oral antibiotic(s) to intravenous antibiotic(s) for the treatment of neutropenic cancer patients with fever. The comparison between the two could be started initially (initial oral) or following an initial course of intravenous antibiotic treatment (sequential). DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial eligibility and methodological quality and extracted data. Data concerning mortality, treatment failures and adverse events were extracted from the included studies assuming an 'intention-to-treat' basis for the outcome measures whenever possible. Risk ratios (RR) with 95% confidence intervals (CI) were estimated for dichotomous data. Risk of bias assessment was also made in line with methodology of The Cochrane Collaboration. MAIN RESULTS Twenty-two trials (3142 episodes in 2372 patients) were included in the analyses. The mortality rate was similar when comparing oral to intravenous antibiotic treatment (RR 0.95, 95% CI 0.54 to 1.68, 9 trials, 1392 patients, median mortality 0, range 0% to 8.8%). Treatment failure rates were also similar (RR 0.96, 95% CI 0.86 to 1.06, all trials). No significant heterogeneity was shown for all comparisons but adverse events. The effect was stable in a wide range of patients. Quinolones alone or combined with another antibiotic were used with comparable results. Adverse reactions, mostly gastrointestinal, were more common with oral antibiotics. AUTHORS' CONCLUSIONS Based on the present data, oral treatment is an acceptable alternative to intravenous antibiotic treatment in febrile neutropenic cancer patients (excluding patients with acute leukaemia) who are haemodynamically stable, without organ failure, and do not have pneumonia, infection of a central line or a severe soft-tissue infection. The wide CI for mortality allows the present use of oral treatment in groups of patients with an expected low risk for mortality, and further research should be aimed at clarifying the definition of low risk patients.

Abstract
Background: No evidence-based guidelines or protocols to treat the infection-related symptoms in cancer patients with terminal stages have been established. Materials and Methods: We retrospectively analyzed all the patients with terminal stage cancer who died between April 2009 and March 2010. The patients’ background, the prevalence of infection and clinical outcomes, pathogens isolated, antibiotics used, and whether blood cultures and some of examinations were performed or not were evaluated. Results: A total of 62 (44 males and 18 females) patients were included in this study. The median age was 73 years (35–98 years). The most common cancer was that of the lung (n =59, 95.2%). A total of 32 patients were diagnosed with the following infections: Infection of respiratory tract in 27 (84.4%), of urinary tract in 4 (12.5%), and cholangitis in 1 (3.1%). Two cases (6.3%) had pneumonia complicated with urinary tract infection. Blood cultures and antibiotic therapies were performed in 28 and 30 cases, respectively. Four (14.3%) positive cultures were isolated from the blood obtained from 28 individual patients. As for clinical course, 3 (10%) of them experienced improved symptoms after antibiotic therapy. Twenty-seven (90%) patients were not confirmed as having any symptom improvement. Conclusions: Blood cultures and antibiotic therapy were limited, and might not be effective in terminally ill cancer patients with lung cancer. We suggest that administering an antibiotic therapy without performing a blood culture would be one of choices in those with respiratory tract infections if patients’ life expectancy is short.

Abstract
OBJECTIVE Neutropenia is frequent during treatment of chronic hepatitis C (CHC) with peginterferon and ribavirin. It remains unclear whether neutropenia is associated with infection in CHC. The aim was to study the relationship between neutropenia and infection during treatment with peginterferon and ribavirin for CHC. METHODS A retrospective cohort on 399 patients treated with peginterferon α and ribavirin derived from our hospital database was conducted. The occurrence of infections and their relationship to neutropenia were investigated. Potential risk factors for infection were identified by multivariate analysis. RESULTS During treatment, neutropenia [absolute neutrophil counts (ANC) <1.5 × 10⁹/l] occurred in 251 patients, mild neutropenia [ANC (0.75-1.5) × 10⁹/l] occurred in 132 patients, moderate neutropenia [ANC (0.50-0.75) × 10⁹/l] occurred in 103 patients, and severe neutropenia (ANC<0.50 × 10⁹/l) occurred in 16 patients. Eighty infections (20.1%) occurred, 14 infections (17.5%) were defined as severe. There was no significant difference in infection rate between patients with and without moderate and severe neutropenia (21.0%, 25/119 vs. 19.6%, 55/280; χ²=0.097, P=0.755). There was no significant difference in infection rate between patients with and without peginterferon dose modifications (21.5%, 31/144 vs. 19.2%, 49/255; χ²=0.307, P=0.580). In multivariate logistic regression analysis, the independent factors associated with infection were age (P=0.021), diabetes (P=0.004), and cirrhosis (P=0.012). CONCLUSION Infections during treatment with peginterferon α and ribavirin for CHC are not associated with neutropenia. The independent factors associated with infection are age, diabetes, and cirrhosis.

Abstract
Bacterial infections, particularly those due to gram-positive bacteria, continue to predominate in patients with cancer. Coagulase-negative and coagulase-positive staphylococci and enterococci remain as common pathogenic microorganisms. Clostridium difficile has emerged as a significant pathogen. Major clinical syndromes include vascular catheter-related infection, febrile neutropenia, diarrhea and colitis. Rising antimicrobial resistance among gram-positive bacteria is of serious concern. The clinical utility of penicillin against streptococci and vancomycin against coagulase-negative and coagulase-positive staphylococci and enterococci may be rapidly diminishing. Liberal empiric use of vancomycin during neutropenic fever needs careful reconsideration. Newer promising anti-gram-positive bacterial drugs with activity against methicillin-resistant staphylococci include daptomycin, linezolid, tigecycline and telavancin. However, toxicity concerns, limited data in immunocompromised populations and high cost prevent the widespread use of these drugs among patients with cancer.

Abstract
BACKGROUND We determined whether mannose-binding lectin (MBL) deficiency is associated with an increased risk of febrile neutropenia (FN) and/or infection in pediatric oncology patients. PROCEDURE We systematically searched and reviewed all the literature on MBL and infections in children with cancer, identified from a literature search of Medline, Embase, and Central (1966-April 2010). We extracted information on the type of study, patient characteristics, definition of MBL deficiency, definition of infection and method of detection, follow-up period and the results of the outcome in different groups. The validity of each study was assessed. RESULTS Six cohort studies were retrieved, consisting of 581 children with leukemia (n = 2) or varying types of cancer (n = 4). Many different outcome definitions were used. In only one out of three genotype studies, variant MBL2 genotypes, as well as MBL levels < 1,000 µg/L, were associated with an increased duration of FN. In one additional MBL level study the number of FN episodes, bacteremia and severe bacterial infection were increased in patients with MBL levels < 100 µg/L as compared to those with MBL levels of 100-999 µg/L. Sepsis, pneumonia, viral infection, and fungal infection were not associated with either MBL levels or genotypes in any of the studies. CONCLUSIONS MBL deficiency could not be identified as an independent risk factor for FN or infection in pediatric oncology patients. A multicenter study of children with comparable chemotherapy regimens, relevant and equal outcome definitions and measuring both MBL levels and genotypes, will be required to avoid clinical and methodological inconsistencies.

Abstract
Patients with neoplastic disease are often highly susceptible to severe infections. The following factors influence the types, severity, and response to therapy of these infections: (1) Changing epidemiology of infections; (2) cancer- and/or treatment-associated neutropenia; (3) acquired immune deficiency states such as cellular immune defect; (4) recent development of new-generation diagnostic tools including widely available DNA amplification tests; (5) effective intervention for infection prevention; (6) empiric or presumptive therapy during high-risk periods; (7) availability of new classes of highly active antimicrobial drugs; (8) strategies to promote hosts’ immune response; and (9) future measures. This introductory chapter intended for the reader to become familiar with the important historical milestones in the understanding and development in the field of infectious diseases in immunosuppressed patients with an underlying neoplasms and patients undergoing hematopoietic stem cell transplantation.

Abstract
UNLABELLED Neutropenia during treatment with peginterferon alfa and ribavirin for chronic hepatitis C virus (HCV) infection is a common cause of dose reductions of peginterferon alfa. These reductions are performed to prevent bacterial and fungal infections, which are common during HCV treatment and can be attributed to neutropenia. The aims of this study were to investigate the occurrence of infections and their relation to neutropenia and to identify potential risk factors for infections during HCV treatment. In this single-center cohort study, 2,876 visits of 321 patients treated with peginterferon alfa and ribavirin were evaluated for neutropenia, infections, dose reductions, and potential risk factors for infection during HCV treatment. The baseline mean absolute neutrophil count (ANC) was 3,420 cells/μL, and 16 patients had a baseline ANC of <1,500 cells/μL. During treatment, neutropenia, which was defined as ANC <750 cells/μL, was observed in 95 patients (29.7%) and ANC <375/μL was observed in 16 patients (5%). Ninety-six infections were observed in 70 patients (21.8%). Thirteen infections (13.5%) were defined as severe. Infections were not correlated with neutropenia during treatment. Dose reductions did not lead to a decrease in infection rate. Multivariate logistic regression analysis revealed that age >55 years (odds ratio [OR] 2.06, 95% confidence interval [CI] 1.19-3.56, P = 0.01) and baseline hyperglycemia (OR 2.17, 95% CI 1.15-4.10, P = 0.016) were associated with an increased risk of infection during HCV treatment. Cirrhosis and chronic obstructive pulmonary disease were not risk factors for infection. CONCLUSION Bacterial infections during treatment with peginterferon alfa and ribavirin are not associated with neutropenia. Older patients and patients with poorly controlled diabetes mellitus have a greater risk of developing infections during HCV treatment.

Abstract
BACKGROUND Bloodstream Infections (BSIs) in neutropenic patients often cause considerable morbidity and mortality. Therefore, the surveillance and early identification of patients at high risk for developing BSIs might be useful for the development of preventive measures. The aim of the current study was to assess the predictive power of three scoring systems: Infection Probability Score (IPS), APACHE II and KARNOFSKY score for the onset of Bloodstream Infections in hematology-oncology patients. METHODS A total of 102 patients who were hospitalized for more than 48 hours in a hematology-oncology department in Athens, Greece between April 1st and October 31st 2007 were included in the study. Data were collected by using an anonymous standardized recording form. Source materials included medical records, temperature charts, information from nursing and medical staff, and results on microbiological testing. Patients were followed daily until hospital discharge or death. RESULTS Among the 102 patients, Bloodstream Infections occurred in 17 (16.6%) patients. The incidence density of Bloodstream Infections was 7.74 per 1,000 patient-days or 21.99 per 1,000 patient-days at risk. The patients who developed a Bloodstream Infection were mainly females (p = 0.004), with twofold time mean length of hospital stay (p < 0.001), with fourfold time mean length of neutropenia (p < 0.001), with neutropenia < 500 (p < 0.001), suffered mainly from acute myeloid leukemia (p < 0.001), had been exposed to antibiotics (p = 0.045) and chemotherapy (p = 0.023), had a surgery (p = 0.048) and a Hickman catheter (p = 0.025) as compared to the patients without Bloodstream Infection. The best cut-off value of IPS for the prediction of a Bloodstream Infection was 10 with a sensitivity of 75% and specificity of 70.9% CONCLUSION Between the three different prognostic scoring systems, Infection Probability Score had the best sensitivity in predicting Bloodstream Infections.

Abstract
All bacterial isolates from 7058 patients admitted to haemato-oncology wards at National Taiwan University Hospital between 2002 and 2006 were characterized. In total 1307 non-duplicate bloodstream isolates were made from all patients with haematological malignancy; 853 (65%) of these were from neutropenic patients. Gram-negative bacteria predominated (60%) in neutropenic isolates with Escherichia coli (12%), Klebsiella pneumoniae (10%), Acinetobacter calcoaceticus-baumannii complex (6%), and Stenotrophomonas maltophilia (6%) the most frequent. Coagulase-negative staphylococci (19%) and Staphylococcus aureus (4%) were the most common Gram-positive pathogens. Resistance to ciprofloxacin was found in 50% of E. coli and 20% of K. pneumoniae isolates from neutropenic patients. Extensively drug-resistant A. calcoaceticus-baumannii complex and vancomycin-resistant enterococci were also found during the study period. Emerging antimicrobial resistant pathogens are an increasing threat to neutropenic cancer patients.

Abstract
Literature provides no specific data concerning the type and the risk factors for infection in adult patients with acute lymphoblastic leukemia (ALL). We retrospectively analyzed 97 adult ALL patients who underwent conventional chemotherapy during a 14-year period with the aim to assess the incidence and the factors affecting onset and outcome of infections. We found that during induction therapy 50% of patients developed infection, mainly caused by gram-negative bacteria and with a mortality rate of 11%. In multivariate analysis age > 60 years was significantly associated with more infections (P = 0.04) and higher related mortality (P = 0.03). Moreover, in 22% of patients infectious complications occurred during consolidation or maintenance therapy. Mortality rate of these infections, mostly due to opportunistic pathogens, was 16%. Factors affecting mortality was the cumulative dose of methylprednisolone given during induction therapy ( < or = 2600 mg = 31% vs. > 2600 mg = 69%; P = 0.03). Among neutropenic patients, adults with ALL represent a peculiar population since they frequently develop gram negative infections during induction and opportunistic infections during post-remission treatments. Advanced age and high-dose methylprednisolone result the major risk factors for infection related mortality in the former therapeutic phase and in the latter one, respectively.

Abstract
The urgent need to treat presumptive bacterial or fungal infections in neutropenic patients has meant that initial therapy is empiric and based on the pathogens most likely to be responsible, and drug resistance. The traditional empirical treatment in Norway has been penicillin G and an aminoglycoside, and this combination has been criticized over recent y. We wished to analyse the microbiological spectrum and susceptibility patterns of pathogens causing bacteraemia in febrile neutropenic patients. This was a prospective multicentre study. During the study period of 2 y, a total of 282 episodes of fever involving 243 neutropenic patients was observed. In 34% of episodes bacteraemia was documented. Overall, 40% of the episodes were caused by Gram-positive organisms, 41% by Gram-negative organisms and 19% were polymicrobial. The most frequently isolated bacteria were Escherichia coli (25.6%), a- and non-haemolytic streptococci (15.6%), coagulase-negative staphylococci (12.4%) and Klebsiella spp. (7.4%). None of the Gram-negative isolates was resistant to gentamicin, meropenem, ceftazidime or ciprofloxacin. Only 5 coagulase-negative staphylococci isolates were resistant to both penicillin G and aminoglycoside. The overall mortality rate was 7%, and 1.2% due to confirmed bacteraemic infection.

Abstract
Aggressive chemotherapy has a deleterious effect on all components of the defense system of the human body. The resulting neutropenia as well as injury to the pulmonary and gastrointestinal mucosa allow pathogenic micro-organisms easy access to the body. The symptoms of an incipient infection are usually subtle and limited to unexplained fever due to the absence of granulocytes. This is the reason why prompt administration of antimicrobial agents while waiting for the results of the blood cultures, the so-called empirical approach, became an undisputed standard of care. Gram-negative pathogens remain the principal concern because their virulence accounts for serious morbidity and a high early mortality rate. Three basic intravenous antibiotic regimens have evolved: initial therapy with a single antipseudomonal β-lactam, the so-called monotherapy; a combination of two drugs: a β-lactam with an aminoglycoside, a second β-lactam or a quinolone; and, thirdly, a glycopeptide in addition to β-lactam monotherapy or combination. As there is no single consistently superior empirical regimen, one should consider the local antibiotic susceptibility of bacterial isolates in the selection of the initial antibiotic regimen. Not all febrile neutropenic patients carry the same risk as those with fever only generally respond rapidly, whereas those with a clinically or microbiologically documented infection show a much slower reaction and less favorable response rate. Once an empirical antibiotic therapy has been started, the patient must be monitored continuously for nonresponse, emergence of secondary infections, adverse effects, and the development of drug-resistant organisms. The averageduration of fever in serious infections in eventually successfully treated neutropenic patients is 4–5 days. Adaptations of an antibiotic regimen in a patient who is clearly not responding is relatively straightforward when a micro-organism has been isolated; the results of the cultures, supplemented by susceptibility testing, will assist in selecting the proper antibiotics. The management of febrile patients with pulmonary infiltrates is complex. Bronchoscopy and a high resolution computer-assisted tomographic scan represent the cornerstones of all diagnostic procedures, supplemented by serological tests for relevant viral pathogens and for aspergillosis. Fungi have been found to be responsible for two thirds of all superinfections that may surface during broad-spectrum antibiotic treatment of neutropenic patients. Antibiotic treatment is usually continued for a minimum of 7 days or until culture results indicate that the causative organism has been eradicated and the patient is free of major signs and symptoms. If a persistently neutropenic patient has no complaints and displays no evidence of infection, early watchful cessation of antibiotic therapy or a change to the oral regimen should be considered.

Abstract
The purpose of this study was to determine if the Multinational Association for Supportive Care in Cancer (MASCC) risk-index score is able to predict the outcome of febrile neutropenia in patients with underlying hematological malignancy and to look at the other possible predictors of outcome. A retrospective study of 116 episodes of febrile neutropenia in patients who were admitted to the hematology ward of a local medical center in Malaysia between January 1st 2004 and January 31st 2005. Patient characteristics and the MASCC score were compared with outcome. The MASCC score predicted the outcome of febrile neutropenic episodes with a positive predictive value of 82.9%, a sensitivity of 93%, and specificity of 67%. Other predictors of a favorable outcome were those patients who had lymphomas versus leukemias, duration of neutropenia of less than 7 days, low burden of illness characterized by the absence of an infective focus and absence of lower respiratory tract infection, a serum albumin of >25 g/l, and the absence of gram-negative bacteremia on univariate analysis but only serum albumin level, low burden of illness, and presence of respiratory infection were significantly associated with unfavorable outcome after multivariate analysis. The MASCC score is a useful predictor of outcome in patients with febrile neutropenia with underlying hematological malignancies. This scoring system may be adapted for use in local settings to guide the clinical management of patients with this condition.

Abstract
Significant changes in the epidemiology of infectious complications in cancer patients have emerged during the past decade. Among blood culture isolates from febrile neutropenic patients, Gram-positive pathogens have become predominant, and an increasing spread of methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococci must be taken into consideration. Risk factors such as indwelling venous catheters or chemotherapy-induced mucosal damage are associated with an increased incidence of Gram-positive infections. Invasive fungal infections, particularly invasive aspergillosis, have become most important in severely neutropenic patients and are associated with fatality rates of 40-60%. The use of nucleoside analogues and the CD52-antibody alemtuzumab induce a long-lasting lymphopenia facilitating the occurrence of opportunistic infections specifically caused by viruses and fungi. In elderly patients undergoing intensive myelosuppressive chemotherapy, infectious complications may be managed as successfully as in younger patients by appropriate antimicrobial therapy. The broad use of fluoroquinolones for antibacterial prophylaxis in neutropenic patients may lead to very high resistance rates among Gram-negative bacilli such as E. coli. In patients given moxifloxacin for infection prevention, unacceptably large numbers of Clostridium difficile-associated enterocolitis have been reported.

Abstract
BACKGROUND Information on the incidence of infectious complications during for treatment for high risk neuroblastoma (HR-NB) is limited. Bacteremias and invasive mycoses may be considered surrogate markers of the infection burden. PATIENTS AND METHODS Data on bacteremias and invasive mycoses occurring during 3 consecutive protocols for front line (NB-89; NB-92; NB-97) or salvage therapy (TVD) for HR-NB were reviewed. The cumulative risk of developing a first episode and the rate of infections during the entire length of each protocol were evaluated. RESULTS Front line protocols were given to 80 patients for a total of 22,070 days at risk; salvage treatment was given to 24 children for 2,909 days at risk. During front line therapy 41 infectious episodes were diagnosed in 29 (36%) patients, for a 45% cumulative risk and an infection rate (IR) of 0.19/100 patient-days-at risk. Salvage therapy determined five infectious episodes in four (17%) patients, with a 39% cumulative risk, and an IR of 0.17. The IR during the phase of high dose chemotherapy with hematopoietic stem cell rescue (megatherapy) included in the three front line protocols decreased over time (1.54 in NB-89; 0.52 in NB-92 and 0.0 in NB 97; P = 0.001), possibly because of the use of less aggressive conditioning regimens, without radiotherapy. CONCLUSIONS The IRs of protocols for HR-NB did not change over time. The megatherapy-related phases are those at highest risk.

Abstract
Children with cancer have an overall chance of survival of 70-80%. Despite significant advances in supportive care during the last years, infections remain a major cause of therapy-associated morbidity and death. Between January and December 2000, oncology patients (ONC) treated on a pediatric oncology ward after chemotherapy (n = 109), loco-regional thermochemotherapy (n = 13), or hematopoietic stem cell (HSCT) transplantation (n = 35) suffered a total of 249 febrile infectious complications (HSCT 40/ONC 209). These episodes were analyzed retrospectively and compared with 125 ONC patients with 133 febrile infections in 1980/81. The relative incidence of fever of unknown origin (FUO) decreased from 1980/81 to 2000 (p <.001). The frequency of bloodstream infections (BSI) in febrile episodes was comparable in both periods with 37% (50/135) in 1980 and 29% (72/249) in 2000. In both periods, gram-positive bacteria were the most frequent organisms, whereas gram-negative organisms were detected in approximately 20% of BSI. In 1980/81 microbiologically (MDI) or clinically documented infections (CDI) were not detected, whereas in 2000 27% of all infectious were MDI/CDI. During the last 20 years, improved diagnostic tools have resulted in an increased detection rate of infectious agents causing febrile episodes in pediatric cancer patients. The comparison of the two observation periods did not reveal a change in the microbiologic spectrum. Despite the fact that in 2000 more patients were treated with intensified chemotherapy because of relapse, infection-related mortality was unchanged compared to 1980/81. This observation may indicate a sufficient preemptive antibacterial therapy followed by better diagnostic tools and goal-oriented treatment.

Abstract
OBJECTIVE To assess the variation in the current UK management strategies for the treatment of febrile neutropenia in childhood. DESIGN AND SETTING A postal survey of all 21 United Kingdom Children's Cancer Study Group (UKCCSG) centres assessing and collating local policies, protocols or guidelines relating to the management of febrile neutropenia. Further direct contact was undertaken to clarify any uncertainties. RESULTS All 21 centres provided information. The policies used to manage febrile neutropenia in the centres around the UK vary in almost every aspect of management. Definitions of fever ranged from a persistent temperature of >37.5 degrees C to a single reading of >39 degrees C. Neutropenia was inconsistently defined as an absolute neutrophil count of <1x10(9), <0.75x10(9 )or <0.5x10(9). Choices of antibiotic approaches, empirical modifications and antistaphylococcal treatment were different in each protocol. The use of risk stratification was undertaken in 11 centres, with six using a policy of reduced intensity therapy in low risk cases. Empirical antifungal treatment was very poorly described and varied even more widely. CONCLUSIONS There was a great deal of variation in definitions and treatment of febrile neutropenia in the UKCCSG children's cancer treatment centres. A degree of variation as a result of local microbiological differences is to be expected, but beyond this we should seek to standardise the core of our approach to defining fever and neutropenia, risk stratification and duration of empirical therapy in a way that maintains safety, minimises resource utilisation and maximises quality of life.

Abstract
OBJECTIVES This study was initiated to determine the local profile of blood culture isolates and antibiotic sensitivities in febrile neutropenic patients following chemotherapy, and to establish if any modifications to treatment guidelines are necessary. DESIGN A total of 116 episodes of febrile neutropenia admitted to the adult hematology ward at a university medical center in Malaysia were studied retrospectively from January 2004 to January 2005. RESULTS The study showed 43.1% of febrile neutropenic episodes had established bacteremia. Gram-negative bacteria accounted for 60.3% of isolates. Sensitivities of Gram-negative bacteria to the antibiotics recommended in the Infectious Diseases Society of America (IDSA) guidelines were 86.1-97.2%. Coagulase-negative staphylococci were the most common Gram-positive organisms isolated (23.3%). The majority of these were methicillin-resistant. CONCLUSIONS Carbapenem monotherapy, as recommended in the 2002 IDSA guidelines, is effective treatment for the infections most often encountered at our center. Combination therapy with an aminoglycoside should be considered when using ceftazidime, cefepime or piperacillin-tazobactam, particularly in high-risk patients. Vancomycin should be used if a Gram-positive organism is suspected or isolated.

Abstract
Defining the severity of an infection can play a central role for a correct therapeutic choice, avoiding inadequate antimicrobial treatments. Severe bacterial infections are, in fact, characterized by high morbidity and mortality rates so that the appropriateness of therapy can have a profound clinical impact. Indeed, initial inappropriate empirical therapies, and the further need to modify them, substantially increase the mortality risk. Several strategies have been suggested to improve the clinical outcome of patients affected by severe bacterial infections, such as the use of guidelines, use of antibiotics in combination, de-escalation therapy, cycling therapy and the use of infectious disease specialist consultation. A closer collaboration between the medical staff in the wards and infectious disease specialists can possibly bridge the gap between different strategies and individual needs of the patient, thereby improving the decision-making process.

A randomized, open-label, multicenter comparative study of the efficacy and safety of piperacillin-tazobactam and cefepime for the empirical treatment of febrile neutropenic episodes in patients with hematologic malignancies. Clin Infect Dis 2006; 43:447-59.

Abstract
BACKGROUND The empirical treatment of febrile, neutropenic patients with cancer requires antibacterial regimens active against both gram-positive and gram-negative pathogens. This study was performed to demonstrate the noninferiority of monotherapy with piperacillin-tazobactam, compared with cefepime. METHODS We conducted a randomized-controlled, open-label, multicenter clinical trial among high-risk patients from 34 university-affiliated tertiary care medical centers in the United States, Canada, and Australia who were undergoing treatment for leukemia or hematopoietic stem cell transplantation and were hospitalized for empirical treatment of febrile neutropenic episodes. Patients received piperacillin-tazobactam (4.5 g every 6 h) or cefepime (2 g every 8 h) intravenously. The primary outcome was success (defined by defervescence without treatment modification) at 72 h of treatment, end of treatment, and test of cure in the modified intent-to-treat analysis. Secondary outcomes included time to defervescence, microbiological efficacy, the additional use of glycopeptide antibiotics, emergence of resistant bacteria, and safety. RESULTS For 528 subjects (265 received piperacillin-tazobactam and 263 received cefepime), success rates were 57.7% and 48.3%, respectively (P = .04) at the 72-h time point, 39.6% and 31.6% (P = .06) at end of treatment, and 26.8% and 20.5% (P = .11) at the test-of-cure visit. The analyses demonstrated noninferiority for piperacillin-tazobactam at all time points (P< or = .0001). Treatment with piperacillin-tazobactam was independently associated with treatment success in multivariate analysis (odds ratio, 1.65; 95% confidence interval, 1.04-2.64; P = .035). Both regimens were well tolerated. CONCLUSIONS This study demonstrates the noninferiority and safety of piperacillin-tazobactam monotherapy, compared with cefepime, for the empirical treatment of high-risk febrile neutropenic patients with cancer.

Abstract
Acute leukemia is common in the elderly and, due to the aging population and poorer prognosis, represents a major challenge. Elderly acute leukemia patients have been arbitrarily defined as >or=55 to 65 years of age and are underrepresented in clinical trials. There are physiologic differences between elderly and non-elderly patients. A comprehensive understanding of these differences allows the development of a systematic approach to assessing the risks for treatment-related complications. Use of a comprehensive geriatric assessment (CGA), initially developed and validated in the general geriatric population, may allow more accurate assessment of the likelihood of chemotherapy-induced complications and allow for proactive risk minimization. Once complications to therapy develop, aggressive treatment is essential. Treatment related to common complications that arise from therapy will be reviewed. Further research directed at this population is required.
