Abstract
BACKGROUND The effect of systemic treatment of ventilator-associated pneumonia (VAP) with telavancin, a semisynthetic lipoglycopeptide with good penetration in vitro biofilms, has not been tested in vivo during mechanical ventilation. This study examined the efficacy of telavancin compared with linezolid against endotracheal tube (ETT) biofilms in a porcine model of methicillin-resistant Staphylococcus aureus (MRSA) VAP. METHODS VAP was induced in 18 pigs by instilling 107 colony-forming units (CFU/mL) of an MRSA strain susceptible to telavancin and linezolid into each pulmonary lobe. Randomization into three groups was done at pneumonia diagnosis: control (IV glucose 0.5% solution q24); linezolid (10 mg/kg q12) and telavancin groups (22.5 mg/kg q24). After 72 h of MV, data regarding bronchoalveolar lavage (BAL), tracheal aspirate (TA), ETT MRSA biofilm load and thickness measured by scanning electron microscopy were obtained. RESULTS All 18 pigs completed the study. MRSA was isolated in 100% of ETTs from the control and linezolid groups and in 67% from the telavancin group. Telavancin treatment presented a lower MRSA load compared to the control and linezolid treatments (telavancin median [interquartile range (IQR)] = 1.94 [0.00-5.45], linezolid 3.99 [3.22-4.68] and control 4.93 [4.41-5.15], P = 0.236). Telavancin treatment also resulted in the lowest biofilm thickness according to the SEM (4.04 [2.09-6.00], P < 0.001). We found a positive correlation between ETT and BAL load (rho = 0.511, P = 0.045). CONCLUSIONS In our VAP model, systemic telavancin treatment reduced ETT MRSA occurrence, load, and biofilm thickness. Our findings may have a bearing on ICU patients' clinical outcomes.

Abstract
BACKGROUND Oritavancin, a long-acting lipoglycopeptide approved for use in acute bacterial skin and skin structure infections, has limited data evaluating use in serious infections due to Gram-positive organisms. We aimed to assess the effectiveness and safety of oritavancin for consolidative treatment of Gram-positive bloodstream infections (BSI), including infective endocarditis (IE). METHODS We conducted a retrospective cohort study evaluating adult patients admitted to University of Colorado Hospital from March 2016 to January 2022 who received ≥ 1 oritavancin dose for treatment of Gram-positive BSI. Patients were excluded if the index culture was drawn at an outside facility or were > 89 years of age. The primary outcome was a 90-day composite failure (clinical or microbiological failure) in those with 90-day follow-up. Secondary outcomes included individual components of the primary outcome, acute kidney injury (AKI), infusion-related reactions (IRR), and institutional cost avoidance. RESULTS Overall, 72 patients were included. Mean ± SD age was 54 ± 16 years, 61% were male, and 10% had IE. Organisms most commonly causing BSI were Staphylococcus aureus (68%, 17% methicillin-resistant), followed by Streptococcus spp. (26%), and Enterococcus spp. (10%). Patients received standard-of-care antibiotics before oritavancin for a median (IQR) of 11 (5-17) days. Composite failure in the clinically evaluable population (n = 64) at 90-days occurred in 14% and was composed of clinical and microbiological failure, which occurred in 14% and 5% of patients, respectively. Three patients (4%) experienced AKI after oritavancin, and two (3%) experienced an IRR. Oritavancin utilization resulted in earlier discharge for 94% of patients corresponding to an institutional cost-avoidance of $3,055,804 (mean $44,938/patient) from 1,102 hospital days saved (mean 16 days/patient). CONCLUSIONS The use of oritavancin may be an effective sequential therapy for Gram-positive BSI to facilitate early discharge resulting in institutional cost avoidance.

Abstract
PURPOSE The purpose of this study was to assess the potential of new lipoglycopeptides as novel topical therapies for improved treatment of recalcitrant ocular infections. We evaluated the in vitro antimicrobial activity of oritavancin, dalbavancin, and telavancin compared with vancomycin (VAN) against a large collection of ocular staphylococcal isolates and their cytotoxicity on human corneal epithelial cells (HCECs). METHODS Antimicrobial susceptibility testing was performed by broth microdilution against 223 Staphylococcus spp. clinical isolates. Time-kill kinetics were determined for methicillin-resistant strains of Staphylococcus aureus (MRSA) (n = 2) and Staphylococcus epidermidis (MRSE) (n = 1). In vitro cytotoxicity assays were performed with AlamarBlue and live/dead staining on HCECs. RESULTS All new lipoglycopeptides showed strong in vitro potency against ocular staphylococci, including multidrug-resistant MRSA strains, with dalbavancin showing a slightly higher potency overall [minimum inhibitory concentration (MIC) 90 0.06 μg/mL] compared with telavancin and oritavancin (MIC 90 0.12 μg/mL), whereas VAN had the lowest potency (MIC 90 2 μg/mL). Oritavancin exerted rapid bactericidal activity within 1 h for MRSA and 2 h for MRSE. All other drugs were bactericidal within 24 h. At a concentration commonly used for topical preparations (25 mg/mL), cytotoxicity was observed for VAN after 5 min of incubation, whereas reduction in HCEC viability was not seen for telavancin and was less affected by oritavancin and dalbavancin. Cytotoxicity at 25 mg/mL was seen for all drugs at 30 and 60 min but was significantly reduced or undetected for lower concentrations. CONCLUSIONS Our study demonstrates that new lipoglycopeptides have substantially better in vitro antimicrobial activity against ocular staphylococcal isolates compared with VAN, with a similar or improved toxicity profile on HCECs.

Abstract
The opioid overdose epidemic is one of the leading causes of death in adults. Its devastating effects have included not only a burgeoning overdose crisis but also multiple converging infectious diseases epidemics. The use of both opioids and other substances through intravenous (IV) administration places individuals at increased risks of infectious diseases ranging from invasive bacterial and fungal infections to human immunodeficiency virus (HIV) and viral hepatitis. In 2012, there were 530,000 opioid use disorder (OUD)-related hospitalizations in the United States (US), with $700 million in costs associated with OUD-related infections. The scale of the crisis has continued to increase since that time, with hospitalizations for injection drug use-related infective endocarditis (IDU-IE) increasing by as much as 12-fold from 2010 to 2015. Deaths from IDU-IE alone are estimated to result in over 7,260,000 years of potential life lost over the next 10 years. There have been high-profile injection-related HIV outbreaks, and injection drug use (IDU) is now the most common risk factor for hepatitis C virus (HCV). As this epidemic continues to grow, clinicians in all aspects of medical care are increasingly confronted with infectious complications of IDU. This review will describe the pathogenesis, clinical syndromes, epidemiology, and models of treatment for common infectious complications among persons who inject drugs (PWIDs).

Abstract
Background: Pulmonary disease caused by Mycobacterium abscessus (M. abscessus) spreads around the world, and this disease is extremely difficult to treat due to intrinsic and acquired resistance of the pathogen to many approved antibiotics. M. abscessus is regarded as one of the most drug-resistant mycobacteria, with very limited therapeutic options. Methods: Whole-cell growth inhibition assays was performed to screen and identify novel inhibitors. The IC50 of the target compounds were tested against THP-1 cells was determined to calculate the selectivity index, and then time–kill kinetics assay was performed against M. abscessus. Subsequently, the synergy of oritavancin with other antibiotics was evaluated by using checkerboard method. Finally, in vivo efficacy was determined in an immunosuppressive murine model simulating M. abscessus infection. Results: We have identified oritavancin as a potential agent against M. abscessus. Oritavancin exhibited time-concentration dependent bactericidal activity against M. abscessus and it also displayed synergy with clarithromycin, tigecycline, cefoxitin, moxifloxacin, and meropenem in vitro. Additionally, oritavancin had bactericidal effect on intracellular M. abscessus. Oritavancin significantly reduced bacterial load in lung when it was used alone or in combination with cefoxitin and meropenem. Conclusions: Our in vitro and in vivo assay results indicated that oritavancin may be a viable treatment option against M. abscessus infection.

Abstract
OBJECTIVES The in vitro antimicrobial activities of telavancin and comparator antimicrobials were evaluated against recent Staphylococcus aureus (S. aureus) clinical isolates collected in the United States of America (USA). METHODS A total of 15882 S. aureus isolates were collected (2014-2016) as part of the SENTRY Antimicrobial Surveillance Program from sites located in all US Census Bureau divisions. Broth microdilution MIC values were measured using current reference methods. Data were stratified by year and census division, and resistance rates were analysed for significant trends. Previously published data on methicillin-resistant S. aureus (MRSA) and multidrug-resistant (MDR) MRSA isolates (collected 2011-2013) were merged with the current isolate set to examine longer term resistance trends. RESULTS Telavancin antimicrobial activity against MRSA and MDR MRSA isolates (MIC50/90 values, 0.03/0.06μg/mL for both subsets) remained unchanged over the 3-year surveillance period, and all isolates were susceptible to telavancin. No difference in telavancin activity was noted when MIC data were stratified by year or US Census Bureau division. When merged data (2011-2016) were analysed, the MRSA rate decreased for the entire USA and six individual census divisions, although the overall rate remained considerable. The overall US MDR MRSA rate also remained considerable and was unchanged from 2011-2016. CONCLUSIONS The sustained potent activity of telavancin against US S. aureus isolates (100% susceptible) and the high rates of MRSA and MDR MRSA in the USA support the continued use of telavancin to treat indicated serious infections caused by S. aureus.

Abstract
OBJECTIVE To assess critically oritavancin, a second-generation lipoglycopeptide, for the treatment of Acute Bacterial Skin and Skin Structure Infections caused by susceptible Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus. METHOD An evaluation report of oritavancin in Acute Bacterial Skin and Skin Structure Infections was carried out according to the methodology of the Group for drug evaluation, standardization and research in drug selection of the Spanish Society of Hospital Pharmacy (SEFH)1, with the MADRE 4.0 program. A search was made in PubMed, in the web www.clinicaltrials. gov, Embase, PubMed and UptoDate. The European Medication Agency and Food and Drug Administration evaluation reports were also used. RESULTS Single-dose oritavancin demonstrated its non-inferiority efficacy versus vancomycin in Acute Bacterial Skin and Skin Structure nfections, with a similar safety profile. Its potential advantage over other therapeutic alternatives lies in its administration in single dose and in its no need for plasma levels monitoring, which would allow its administration on an outpatient basis. Regarding to the other alternative possibilities of oral (linezolid, tedizolid) or IM (teicoplanin) treatment, oritavancin would improve the adherence to the treatment. Although oritavancin could be more efficient in certain scenarios (outpatient treatment versus inpatient treatment with alternatives), there are no convincing studies in this regard so far. On the other hand, alternative drugs above-mentioned, can also allow outpatient treatment, reducing advantages of oritavancin and further increasing cost differences. Therefore, given that the efficacy is similar to the alternatives, a cost minimization analysis could be considered. CONCLUSIONS Oritavancin is comparable in terms of efficacy and safety to the existing alternatives in Acute Bacterial Skin and Skin Structure Infections, without improvements in the cost-effectiveness ratio, because of the proposed positioning is to consider it for the treatment of vancomycinresistant enterococcal infection in adult patients when the use of linezolid or tedizolid is contraindicated.

Abstract
Acute bacterial skin and skin structure infections (ABSSSI) are some of the most commonly encountered infections worldwide. Hospitalizations as a result of ABSSSI are associated with high mortality. This article discusses the role of oritavancin and dalbavancin, two new lipoglycopeptides, in the context of the other I.V. available standard therapy options.
