Abstract
Carbapenem-resistant Enterobacteriaceae (CRE) infections are associated with high morbidity and mortality rates in haematopoietic cell transplantation (HCT) recipients. Factors like mucositis, neutropenia, prolonged hospital stay, and frequent use of prophylactic antimicrobials make HCT recipients especially susceptible to CRE infections. Low culture positivity rates, delay in microbiological diagnosis, and resistance to empirical antimicrobial therapy for febrile neutropenia are responsible for high mortality rates in HCT recipients infected with CRE. In this review we discuss the epidemiology, diagnosis, and management of CRE infections with particular emphasis on patients undergoing HCT. We emphasise the need for preventive strategies like multidisciplinary antimicrobial stewardship, and pre-emptive screening for CRE colonisation in prospective HCT patients as measures to mitigate the adverse impact of CRE on HCT outcomes. Newer diagnostic tests like polymerase chain reaction and matrix-assisted laser desorption ionisation-time of flight (MALDI-TOF) assay that enable earlier and better identification of CRE isolates are discussed. Antimicrobial agents available against CRE, including newer agents like ceftazidime-avibactam and meropenem-vaborbactam, have been reviewed. We also discuss the data on promising experimental treatments against CRE: phage therapy and healthy donor faecal microbiota transplant. Finally, this review puts forth recommendations as per existing literature on diagnosis and management of CRE infections in blood and marrow transplant (BMT) unit.

Abstract
BACKGROUND Antimicrobial de-escalation (ADE) is a strategy of antimicrobial stewardship, aiming at preventing the emergence of antimicrobial resistance (AMR) by decreasing the exposure to broad-spectrum antimicrobials. There is no high-quality research on ADE and its effects on AMR. Its definition varies and there is little evidence-based guidance for clinicians to use ADE in the intensive care unit (ICU). METHODS A task force of 16 international experts was formed in November 2016 to provide with guidelines for clinical practice to develop questions targeted at defining ADE, its effects on the ICU population and to provide clinical guidance. Groups of 2 experts were assigned 1-2 questions each within their field of expertise to provide draft statements and rationale. A Delphi method, with 3 rounds and an agreement threshold of 70% was required to reach consensus. RESULTS We present a comprehensive document with 13 statements, reviewing the evidence on the definition of ADE, its effects in the ICU population and providing guidance for clinicians in subsets of clinical scenarios where ADE may be considered. CONCLUSION ADE remains a topic of controversy due to the complexity of clinical scenarios where it may be applied and the absence of evidence to the effects it may have on antimicrobial resistance.

Abstract
Objective: To review the use of antibiotic stewardship interventions in the adult oncology and hematopoietic cell transplantation (HCT) populations. Data Sources: A literature search of PubMed was performed from inception to October 31, 2019. The general search terms used were oncology, cancer, hematologic malignancy, antimicrobial stewardship, antibiotic stewardship, febrile neutropenia, neutropenic fever, de-escalation, discontinuation, prophylaxis, practice guidelines, clinical pathway, rapid diagnostics, Filmarray, Verigene, MALDI-TOF, antibiotic allergy, and antimicrobial resistance. Study Selection and Data Extraction: Relevant English-language studies describing interventions supported by the Infectious Diseases Society of America guidelines on "Implementing an Antibiotic Stewardship Program" were included. Data Synthesis: Antibiotic stewardship publications in the oncology population have increased in recent years. Studies have described the impact of stewardship interventions, including preauthorization, prospective audit and feedback, implementation of clinical pathways, de-escalation of empirical antibiotics for febrile neutropenia (FN) prior to neutrophil recovery, allergy assessments, and use of rapid diagnostic testing. Many of these interventions have been shown to decrease antibiotic use without increased negative consequences, such as affecting length of stay or mortality. Relevance to Patient Care and Clinical Practice: This review synthesizes available evidence for implementing antibiotic stewardship interventions, particularly de-escalation of antibiotics for FN and implementation of clinical pathways for FN and sepsis, in oncology patients and HCT recipients. Summary tables highlight studies and specific research needs for clinicians. Conclusions: Immunocompromised populations, including oncology patients, have often been excluded from stewardship studies. Antibiotic stewardship is effective in reducing antibiotic consumption and improving outcomes in this patient population, although more quality data are needed.

Abstract
To investigate rates and outcomes of antibiotic de-escalation during pre-engraftment neutropenia in allogeneic hematopoietic stem cell transplantation (HSCT) recipients. 110 consecutive HSCTs performed between January 2013 and March 2014 were analyzed. De-escalation was defined as narrowing the spectrum of antibiotic treatment either within (early) or after 96 hours (late) from starting antibiotics. Discontinuation, considered a form of de-escalation, was defined as stopping antibiotics before engraftment. De-escalation failure was defined as restarting/escalating antibiotics within 96 hours after de-escalation. Predictors of de-escalation were analyzed. Among 102 patients who started antibiotics and were included, 68 (67%) received monotherapy (mainly piperacillin-tazobactam, n = 58), whereas 34 (33%) received combination therapy (mainly meropenem plus glycopeptide, n = 24). Median duration of neutropenia was 17 days. Bloodstream infections (BSIs) were diagnosed in 28 patients (20%). Early de-escalation rate was 25.5% (n = 26) and mostly consisted of reducing the spectrum of β-lactams (n = 11, 42%). In comparison with theoretical scenario of continuing therapy until engraftment, the median savings in terms of antibiotic days were 10 for meropenem, 8 for piperacillin-tazobactam, and 7 for vancomycin. Failure rate of early de-escalation was 15% (4/26). Late de-escalation rate was 30.4% (n = 31) and failure rate 19% (6/31). The rate of de-escalation any time before engraftment was 55.9% (n = 57), including discontinuation in 33 patients (32%). Death at day 60 after HSCT occurred in 3 patients who never underwent de-escalation. Acute myeloid disease and BSIs were independent predictors of early de-escalation. De-escalation, including discontinuation, is feasible and safe in pre-engraftment neutropenia after allogeneic HSCT.

Abstract
Background Carbapenem-resistant Gram-negative bacteria are recognized as a cause of difficult-to-treat infections associated with high mortality. Objectives To perform a systematic review of currently available data on distribution, characteristics and outcome associated with carbapenem-resistant bloodstream infections in adult neutropenic patients. Methods Included studies were identified through Medline, Embase and Cochrane databases between January 1995 and April 2016. Random effect meta-analysis was used to quantify the association between carbapenem resistance and mortality and between carbapenem exposure and resistance. Results A total of 30 studies from 21 countries were included. Overall carbapenem resistance varied from 2% to 53% (median 9%) among studies. Infections due to carbapenem-resistant Pseudomonas spp . were reported in 18 (60%) studies showing high median resistance rates (44% of all carbapenem-resistant Gram-negatives and 19% of Pseudomonas isolates). Resistance of Enterobacteriaceae was less commonly reported and bloodstream infections due to carbapenem-resistant Klebsiella spp. were mainly documented from endemic areas (Greece, Italy, Israel). Carbapenem resistance in Acinetobacter spp. was reported in 9 (30%) studies (median resistance 58% of Acinetobacter isolates). Mortality rates ranged from 33% to 71% (median 50%) in patients with carbapenem-resistant infections. Carbapenem resistance appeared to correlate with mortality (OR 4.89, 95% CI 3.30-7.26) and previous exposure to carbapenems (OR 4.63, 95% CI 3.08-6.96). Conclusions Carbapenem resistance represents a threat to neutropenic patients. In this group, resistance is likely promoted by previous carbapenem use and leads to high mortality rates. The knowledge of resistance patterns is crucial and can direct clinicians in the use of alternatives to carbapenem-based regimens.

Abstract
Modern burn care has led to unprecedented survival rates in burn patients whose injuries were fatal a few decades ago. Along with improved survival, new challenges have emerged in the management of burn patients. Infections top the list of the most common complication after burns, and sepsis is the leading cause of death in both adult and pediatric burn patients. The diagnosis and management of sepsis in burns is complex as a tremendous hypermetabolic response secondary to burn injury can be superimposed on systemic infection, leading to organ dysfunction. The management of a septic burn patient represents a challenging scenario that is commonly encountered by providers caring for burn patients despite preventive efforts. Here, we discuss the current perspectives in the diagnosis and treatment of sepsis and septic shock in burn patients.

Abstract
Extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-PE) are an increasing cause of resistant infections among patients with malignancy. This study sought to estimate the prevalence of bloodstream infections (BSIs) caused by ESBL-PE in this population and to examine regional and temporal differences. The PubMed and EMBASE databases (to 30 April 2016) were searched to identify studies reporting ESBL-PE BSI rates among patients with malignancies. Of 593 non-duplicate reports, 22 studies providing data on 5650 BSI cases satisfied the inclusion criteria. Among all BSIs the pooled prevalence of ESBL-PE was 11% (95% CI 8-15%) and among Gram-negative BSIs it was 21% (95% CI 16-27%). Among patients with haematological malignancies, the pooled ESBL-PE prevalence was 11% (95% CI 8-15%), whereas no studies providing specific data on patients with solid tumours were identified. Stratifying per geographic region, the pooled prevalence was 7% each in Europe (95% CI 5-11%), the Eastern Mediterranean region (95% CI 4-11%) and South America (95% CI 2-14%), 10% in the Western Pacific region (95% CI 4-19%) and 30% in Southeast Asia (95% CI 18-44%). Importantly, there was a 7.1% annual increase in the ESBL-PE incidence (P = 0.004). Overall, ca. 1 in 10 BSIs in patients with malignancy is caused by ESBL-PE and in some areas this rate can be as high as 1 in 3 cases. Additionally, the incidence of these resistant infections is rising. These findings should be considered when selecting empirical antimicrobial therapy and should prompt strict adherence to antimicrobial stewardship.

Abstract
INTRODUCTION Extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE) constitute a global threat and are prevalent in both nosocomial and community settings. These pathogens have been associated with delays in initiation of appropriate antimicrobial therapy and worse clinical outcomes. Patients with solid or hematologic malignancy represent a high-risk population for both colonization and infection with ESBL-PE. Areas covered: A description of the microbiology and epidemiology of the ESBL-PE is presented. Also, we explore studies on ESBL-PE colonization and infection, and examine areas where future research is needed. Expert commentary: ESBL-PE constitute an increasing threat to patients with malignancy. Unfortunately, substantial geographic variations as well as knowledge gaps in certain regions of the world limit our ability to reach conclusions that are valid globally. Furthermore, there is limited evidence regarding the optimal ways to prevent and manage infections caused by ESBL-PE. Research is urgently needed to elucidate these areas and allow the institution of appropriate infection control and antimicrobial stewardship policies and recommendations.
