Daptomycin-containing regimens for treatment of Gram-positive endocarditis.

Purpose: Infective endocarditis (IE) is a severe infection, and a leading cause of mortality and morbidity. Due to its favourable microbiological and pharmacological characteristics, daptomycin is routinely used in clinical practice for treating IE.

Methods: A prospective study was conducted at a large tertiary-care hospital in Italy over an 8-year period (January 2010-January 2018) on all patients with native-valve endocarditis (NVE) or prosthetic-valve endocarditis (PVE) caused by Gram-positive bacteria.

Tedizolid phosphate for the treatment of acute bacterial skin and skin-structure infections: an evidence-based review of its place in therapy.

Introduction: Tedizolid phosphate is an oxazolidinone approved for the treatment of acute bacterial skin and skin-structure infections (ABSSSIs) and active against methicillin-resistant .

Aims: The objective of this article was to review the evidence for the efficacy and safety of tedizolid phosphate for the treatment of ABSSSI.

Evidence Review: Approval of tedizolid phosphate for the treatment of ABSSSI was based on the results of two phase III randomized controlled trials, ESTABLISH-1 (NCT01170221) and ESTABLISH-2 (NCT01421511), comparing 6-day once-daily tedizolid vs 10-day twice-daily linezolid.

ECMM CandiReg-A ready to use platform for outbreaks and epidemiological studies.

Background: Recent outbreaks of Candida auris further exemplify that invasive Candida infections are a substantial threat to patients and healthcare systems. Even short treatment delays are associated with higher mortality rates. Epidemiological shifts towards more resistant Candida spp.

Neuraminidase inhibitors as a strategy for influenza treatment: pros, cons and future perspectives.

: Influenza represents a major public health threat worldwide. Implementation of good personal health and hygiene habits, together with vaccination, is the most effective tools to reduce influenza burden both in community and in healthcare setting. However, achieving adequate vaccination rates is challenging, and vaccination does not always guarantee complete protection.

The safety of treatment options for acute bacterial skin and skin structure infections.

Introduction: Acute bacterial skin and skin-structure infections (ABSSSI) may develop in both in-patients and out-patients, possibly with a severe clinical presentation. Since most phase 3 randomized clinical trials have shown non-inferiority in efficacy across different agents, considerations regarding their different safety profiles inevitably play a crucial role in the everyday choice about which of them should be employed for the treatment of ABSSSI.

Areas Covered: In this review, the authors discuss the safety profile of different treatment options for ABSSSI.

Intensive care management of influenza-associated pulmonary aspergillosis.

Background: Severe pulmonary infections are among the most common reasons for admission to intensive care units (ICU). Within the last decade, increasing reports of severe influenza pneumonia resulting in acute respiratory distress syndrome (ARDS) complicated by Aspergillus infection were published.

Objectives: To provide a comprehensive review of management of influenza-associated pulmonary aspergillosis in patients with ARDS.

Efficacy and Safety of Meropenem-Vaborbactam Versus Best Available Therapy for the Treatment of Carbapenem-Resistant Enterobacteriaceae Infections in Patients Without Prior Antimicrobial Failure: A Post Hoc Analysis.

Introduction: Infections due to Klebsiella pneumoniae carbapenemase (KPC)-producing Enterobacteriaceae are associated with increased morbidity and high mortality. Meropenem-vaborbactam (MV) is a novel β-lactam/β-lactamase inhibitor combination active against KPC-producing Enterobacteriaceae. The aim of this post hoc analysis of the TANGO-II randomized controlled trial was to assess the efficacy of MV versus best available therapy (BAT) in the subgroup of patients without prior antimicrobial failure.

Valuing antibiotics: The role of the hospital clinician.

The global public health threat of antibiotic-resistant infections as well as the lack of new treatments in clinical development is a critical issue. Reasons for this include diminished commercial incentives for pharmaceutical companies to develop new antibiotics, which part-reflects a shift in antibiotic marketing paradigm from broad deployment to targeted therapy in relatively small patient populations. Such changes are encouraged by antimicrobial stewardship (AMS).

ESICM/ESCMID task force on practical management of invasive candidiasis in critically ill patients.

Introduction: The term invasive candidiasis (IC) refers to both bloodstream and deep-seated invasive infections, such as peritonitis, caused by Candida species. Several guidelines on the management of candidemia and invasive infection due to Candida species have recently been published, but none of them focuses specifically on critically ill patients admitted to intensive care units (ICUs).

Material And Methods: In the absence of available scientific evidence, the resulting recommendations are based solely on epidemiological and clinical evidence in conjunction with expert opinion.

Prosthetic joint infections: clinical management, diagnosis, and treatment.

Purpose Of Review: Prosthetic joint infections (PJIs) represent one of the most disastrous complications in prosthetic surgery, requiring long hospitalization, prolonged antimicrobial treatment and repeated surgical interventions. No gold standard test to formulate diagnosis exist. A combination of high index of suspicion, physical examination, microbiological and biohumoral investigations is required.

Rationalizing antimicrobial therapy in the ICU: a narrative review.

The massive consumption of antibiotics in the ICU is responsible for substantial ecological side effects that promote the dissemination of multidrug-resistant bacteria (MDRB) in this environment. Strikingly, up to half of ICU patients receiving empirical antibiotic therapy have no definitively confirmed infection, while de-escalation and shortened treatment duration are insufficiently considered in those with documented sepsis, highlighting the potential benefit of implementing antibiotic stewardship programs (ASP) and other quality improvement initiatives. The objective of this narrative review is to summarize the available evidence, emerging options, and unsolved controversies for the optimization of antibiotic therapy in the ICU.

The ideal patient profile for new beta-lactam/beta-lactamase inhibitors.

Purpose Of Review: The worldwide spread of extended-spectrum beta-lactamase (ESBL)-producing bacteria, the overuse of carbapenems, the emergence of carbapenemase-producing organisms and the growing importance of multidrug-resistant and/or extended drug-resistant strains have totally changed prescribers' habits, leading to very few treatment options in many cases. Beta-lactam/beta-lactamase inhibitor (BLBLI) combinations should be considered as an alternative to carbapenems for treating ESBL-producing bacteria and Pseudomonas aeruginosa infections. The purpose of this study was to provide insight concerning the patients who would constitute ideal candidates to receive these new BLBLI combinations.

Effect and Safety of Meropenem-Vaborbactam versus Best-Available Therapy in Patients with Carbapenem-Resistant Enterobacteriaceae Infections: The TANGO II Randomized Clinical Trial.

Introduction: Treatment options for carbapenem-resistant Enterobacteriaceae (CRE) infections are limited and CRE infections remain associated with high clinical failure and mortality rates, particularly in vulnerable patient populations. A Phase 3, multinational, open-label, randomized controlled trial (TANGO II) was conducted from 2014 to 2017 to evaluate the efficacy/safety of meropenem-vaborbactam monotherapy versus best available therapy (BAT) for CRE.

Methods: A total of 77 patients with confirmed/suspected CRE infection (bacteremia, hospital-acquired/ventilator-associated bacterial pneumonia, complicated intra-abdominal infection, complicated urinary tract infection/acute pyelonephritis) were randomized, and 47 with confirmed CRE infection formed the primary analysis population (microbiologic-CRE-modified intent-to-treat, mCRE-MITT).

Risk stratification and treatment of ICU-acquired pneumonia caused by multidrug- resistant/extensively drug-resistant/pandrug-resistant bacteria.

Purpose Of Review: Describe the risk factors and discuss the management of multidrug-resistant (MDR) bacteria responsible for pneumonia among critically ill patients, including methicillin-resistant Staphylococcus aureus, extended spectrum beta-lactamase-producing Enterobactericeae, carbapenem-resistant Enterobactericeae, multidrug resistant Pseudomonas aeruginosa, and Acinetobacter baumannii.

Recent Findings: Multiple factors have been associated with infections because of MDR bacteria, including prolonged hospital stay, presence of invasive devices, mechanical ventilation, colonization with resistant pathogens, and use of broad-spectrum antibiotics. Management of these infections includes the prompt use of appropriate antimicrobial therapy, implementation of antimicrobial stewardship protocols, and targeted active microbiology surveillance.

A prognostic score for the resolution of bacteremia by Gram-negative bacteria resistant to carbapenems.

The management of bacteremia by carbapenem-resistant Gram-negative bacteria (CRGNB) necessitates a surrogate marker for response to treatment. We developed a prognostic score of bacteremia resolution using a test and a validation cohort. In the test cohort, five protein biomarkers were measured in serial daily serum samples from 39 patients with ventilator-associated pneumonia (VAP) and CRGNB bacteremia.

Clinical and pharmacokinetic drug evaluation of delafloxacin for the treatment of acute bacterial skin and skin structure infections.

In the era of multi-drug resistant pathogens, the adequate treatment of skin and skin structure infections remains a challenge for clinicians. Delafloxacin, with its broad spectrum against Gram-positive, Gram-negative and anaerobic organisms, represents a new therapeutic option in this setting, especially when coverage of methicillin-resistant Staphylococcus aureus is required in the empirical or targeted approach. Areas covered: In this drug evaluation, the Authors have reviewed the pharmacokinetic and pharmacodynamic characteristics of delafloxacin.

Invasive Candida Infections in Liver Transplant Recipients: Clinical Features and Risk Factors for Mortality.

Background: Invasive fungal infections remain a leading cause of morbidity and mortality among liver transplant recipients (LTRs). In this patient population, invasive Candida infections (ICIs) account for the large majority of cases. To date, only small studies and case-series analysing clinical presentation and risk factors for mortality in LTRs with ICIs are available.
