Acute bacterial skin and skin structure infections (ABSSSI) and osteoarticular infections compound the burden of morbidity, mortality and prolonged hospitalizations among gram-positive infections. Dalbavancin, a second-generation, intravenous lipoglycopeptide, due to its prolonged half-life, can be a valuable alternative in their treatment when administered as inpatient treatment at the price of an extended hospital stay. Between October 2019 and September 2023, 31 children and adolescents were treated with dalbavancin because of bone and joint infections (n = 12 patients, 39%), ABSSSI (n = 13 patients, 42%), mainly for the limbs, facial cellulitis or complicated ABSSSI (n = 6 patients, 19%), at five Italian pediatric centers...

BACKGROUND: Severe gram-positive infections are frequent in people who inject drugs, and successful completion of treatment presents unique challenges in this population. OBJECTIVES: We aimed to evaluate the feasibility of a long-acting antibiotic, dalbavancin, as an alternative to standard-of-care antibiotics for severe infections due to vancomycin-susceptible pathogens requiring ⩾2 weeks of therapy. DESIGN: We designed an investigator-initiated single-arm unblinded prospective cohort study to evaluate the safety and efficacy of an early switch to dalbavancin in two doses administered 1 week apart...

Nosocomial central nervous system (CNS) infections with carbapenem- and colistin-resistant Gram-negative and vancomycin-resistant Gram-positive bacteria are an increasing therapeutic challenge. Here, we review pharmacokinetic and pharmacodynamic data and clinical experiences with new antibiotics administered intravenously for the treatment of CNS infections by multi-resistant bacteria. Cefiderocol, a new siderophore extended-spectrum cephalosporin, pharmacokinetically behaves similar to established cephalosporins and at high doses will probably be a valuable addition in our therapeutic armamentarium for CNS infections...

Dalbavancin is a long-acting lipoglycopeptide that is registered for the treatment of acute bacterial skin and skin structure infections, and it is also increasingly used for infections that require prolonged antibiotic treatment. Here, we present the results from the first 2 years of a service set up in December 2021 for the therapeutic drug monitoring (TDM) of dalbavancin in clinical settings. In particular, we compared the trough concentration (Cmin) to maximum concentration (Cmax) in patients with osteoarticular infections receiving prolonged treatment with dalbavancin...

Antibiotic resistance is fast spreading globally, leading to treatment failures and adverse clinical outcomes. This review focuses on the resistance mechanisms of the top five threatening pathogens identified by the World Health Organization's global priority pathogens list: carbapenem-resistant Acinetobacter baumannii , carbapenem-resistant Pseudomonas aeruginosa , carbapenem-resistant, extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae , vancomycin-resistant Enterococcus faecium and methicillin, vancomycin-resistant Staphylococcus aureus ...

OBJECTIVES: To retrospectively describe the patterns of use of dalbavancin for treating infections in diabetic patients in Italian and Spanish standard clinical practice. METHODS: DALBADIA [NCT04959799] was a multicenter, observational, retrospective cohort study, conducted in Italy and Spain. The study enrolled 97 adults with type 1 or 2 diabetes mellitus, treated with dalbavancin as per standard clinical practice for a Gram-positive bacterial infection or the Gram-positive component of a mixed infection...

PURPOSE: Dalbavancin, approved in 2014 for Gram-positive acute bacterial skin and skin structure infections (ABSSSI), has pharmacokinetics enabling treatment with one or two doses. Dalbavancin might be useful in outpatient parenteral antibiotic therapy (OPAT) of deep-seated infections, otherwise requiring inpatient admission. We documented our experience with pragmatic dalbavancin use to assess its effectiveness for varied indications, on- and off-label, as primary or sequential consolidation therapy...

INTRODUCTION: The aim of this study was to assess the incidence of Corynebacterium striatum prosthetic joint infections (PJI) to determine if an increase has occurred recently. Moreover, susceptibility testing was conducted on C. striatum preserved isolates to determine antibiotic options for these infections. METHODS: Retrospective review of PJI cases was conducted from 1/2017 through 1/2021 compared to 1/2021 through 7/2022 to determine how many cases of C. striatum have occurred for each of these time points...

The overall low-quality evidence concerning the clinical benefits of different antibiotic regimens for the treatment of infective endocarditis (IE), which has made it difficult to strongly support or reject any regimen of antibiotic therapy, has led to a discrepancy between the available guidelines and clinical practice. In this complex scenario, very recently published guidelines have attempted to fill this gap. Indeed, in recent years several antimicrobials have entered the market, including ceftobiprole, ceftaroline, and the long-acting lipoglycopeptides dalbavancin and oritavancin...

INTRODUCTION: The increasing emergence of bacterial strains with new resistance determinants has become a threat to current antibiotic therapies in recent years. This has prompted research for innovative options with improved efficacy and safety profiles: long-acting glycopeptides, such as dalbavancin and oritavancin, are currently approved for the treatment of acute bacterial skin and skin structure infections (ABSSSI). Their efficacy, microbiological profile, and ease of administration may provide an answer to this challenge, as well as reducing length of stay and hospital costs...

We report the case of a patient with infective endocarditis on a prosthetic aortic valve due to Staphylococcus epidermidis, not a candidate for prosthetic replacement surgery. After three months of supressive treatment with dalbavancin, fever reappears, with growth of S. epidermidis. Susceptibility testing showed new-onset resistance to dalbavancin, with a mutation in walK gene.

This review discusses small molecule antibiotics approved for clinical use in the time frame 2010-2022. This time span saw the approval of four synthetic antibiotics (bedaquiline, pretomanid, delafloxacin, tedizolid), nine natural product derivatives (ceftaroline fosamil, cefiderocol, plazomicin, omadacycline, eravacycline, sarecycline, lefamulin, dalbavancin, oritavancin), and one natural product (fidaxomicin).

BACKGROUND: Infection is the leading cause of morbidity and mortality in patients with left ventricular assist devices (LVADs). Prolonged suppressive therapy should be strongly considered and is often used in patients with recurrent infections when source control cannot be achieved. Dalbavancin is a promising option in patients with LVADs requiring prolonged durations of antibiotic therapy, especially when no oral alternatives are available. METHODS: This case series included 8 patients receiving dalbavancin for the long-term suppression of gram-positive infections at Emory University Hospital and Emory St Joseph's Hospital...

Nonomuraea gerenzanensis (N. gerenzanensis) is known for its ability to biosynthesize A40926, the precursor of the glycopeptide antibiotic (GPA) Dalbavancin. However, challenges and uncertainties related to the genetic manipulation of the rare actinomycetes remain. In order to improve the conjugation transfer of N. gerenzanensis, the crucial factors affecting conjugal transfer were evaluated, including agar medium, mycelial state, donor-recipient ratio, magnesium ion concentration, and antibiotic coverage time firstly...

Dalbavancin represents a promising treatment for cardiovascular prosthetic infections due to its prolonged half-life, bactericidal activity, large spectrum of activity, and excellent biofilm penetration. However, the use of dalbavancin in this setting is limited, and only a few cases have performed therapeutic drug monitoring (TDM) analysis to optimize dosage in suppressive treatments longer than 4 weeks. Our retrospective case series reports the use of dalbavancin in a small cohort of patients with cardiovascular prosthetic infections (cardiac implantable electronic device infections (CEDIs), prosthetic valve endocarditis (PVE), prosthetic vascular graft infections (PVGIs)) treated with dalbavancin as sequential therapy...

Skin and soft tissue infections are a common reason for patients seeking inpatient and outpatient medical care. Surgery is an essential part of managing in many episodes. Careful evaluation of antibiotic therapy could help clinicians in early identification to patients with treatment failure and to consider an alternative approach or a new surgical revision in "focus control". With the arrival of new drugs, there is a need to refine the appropriate drug's decision-making. Drugs with a long half-life (long-acting lipoglycopeptides such as dalbavancin or oritavancin), which allows weekly administration (or even greater), can reduce hospital admission and length of stay with fewer healthcare resources through outpatient management (home hospitalization or day hospitals)...

Dalbavancin is being increasingly used for long-term treatment of subacute and/or chronic staphylococcal infections. Here we implemented and validated a new Bayesian model by means of the MwPharm software for accurately forecasting duration of pharmacodynamic target attainment above the efficacy thresholds of 4.02 or 8.04 mg/L against staphylococci. Forecasting accuracy improved substantially with the a posteriori approach compared to the a priori approach, especially when two measured concentrations were used...

OBJECTIVES: We aimed to describe the efficacy and safety of dalbavancin in treatment of patients with diabetes-related foot osteomyelitis with bone culture confirmation. PATIENTS AND METHODS: Between January 2019 and December 2021, all consecutive patients receiving at least one 1500 mg dose of dalbavancin for diabetes-related foot osteomyelitis were included in a retrospective study. Remission was defined as absence of relapsing infection or need for surgery at the initial or a contiguous site during 6-month follow-up from the last dose of dalbavancin...

PURPOSE: Sternal osteomyelitis is a major complication of cardiac operations performed through median sternotomy. The surgical treatment, which involves the debridement and removal of whole infected and necrotic tissue is the standard of care, although it is sometimes unachievable. This may occur, for instance, when the infectious-inflammatory process invades the anterior mediastinum and tenaciously incorporates one or more of vital anatomical structures. METHODS AND RESULTS: An inoperable case of postoperative sternal osteomyelitis that involved the right ventricle and the right coronary artery, and that was successfully treated using a nonsurgical multidisciplinary approach, is reported here...
