Daptomycin is approved for the treatment of skin and soft tissue infections, Staphylococcus aureus bacteremia, and right-sided native-valve endocarditis (3). There are, however, few data on the efficacy of daptomycin in the treatment of left-sided native-valve endocarditis caused by S. aureus. In a randomized clinical trial, only 1 (11%) of 9 patients treated with intravenous (i.v.) daptomycin at 6 mg/kg daily was cured (9). In a registry of patients at 45 U.S. institutions who received daptomycin for any indication, a successful clinical outcome was achieved in 12 (63%) of 19 cases of left-sided endocarditis caused by S. aureus (14).. The efficacy of daptomycin in left-sided native- or prosthetic-valve S. aureus endocarditis may be improved either by increasing the dose to 10 to 12 mg/kg daily or by achieving synergy by the addition of a second agent. The addition of gentamicin or rifampin did not, however, increase the activity of daptomycin in a rabbit model of methicillin-resistant S. aureus ...
Daptomycin remains as one of the main treatment options for Methicillin-Resistant Staphylococcus aureus (MRSA). Sporadic resistance cases reported in patients treated with either daptomycin or glycopeptides are a growing concern. In a previous study, we described a clinical case of a patient with a community-acquired MRSA infection resistant to daptomycin and with intermediate resistance to vancomycin who developed a recurrent infection with a susceptible isogenic strain. In the present work, we further investigated the sequential events to determine whether the switch from a daptomycin resistance to a susceptible phenotype was due to a phenomenon of resistance reversion or recurrent infection with a susceptible strain. Pairwise competition experiments showed that the susceptible clinical recurrent SA6850 strain had increased fitness when compared to the resistant counterpart SA6820 strain. In fact, although we have demonstrated that reversion of daptomycin resistance to daptomycin susceptible can occur

Pharmacological and pharmacokinetic aspects are reviewed and the current clinical use of daptomycin is presented. Daptomycin seems to be a reliable drug in the treatment of complicated skin and skin structure infections, infective right-sided endocarditis, and bacteremia caused by Gram-positive agents. Its unique mechanism of action and its low resistance
Objectives: Daptomycin is a lipopeptide antimicrobial that is primarily excreted by the kidney. We examined daptomycin bactericidal activity in an in vitro pharmacodynamic model (IVPM) under normal and simulated impaired renal function against methicillin-susceptible Staphylococcus aureus (MSSA) and methicillin-resistant S. aureus (MRSA).. Methods: Two clinical strains MSSA-1199 and MRSA-494 were used in an IVPM. MICs and MBCs were determined according to CLSI. Daptomycin free concentrations were simulated that corresponded to dose regimens of 4, 6 and 8 mg/kg every 24 h at 8 h t1/2 (Scheme I) and every 48 h at 30 h t1/2 (Scheme II). In addition, we simulated daptomycin free concentrations corresponding to fractional dose regimens of 2, 3 and 4 mg/kg every 24 h at 30 h t1/2 (Scheme III). The targeted Cmax free/MIC for 2, 3, 4, 6 and 8 mg/kg against MSSA-1199 ranged from 5.2 to 21.2. The targeted Cmax free/MIC for 2, 3, 4, 6 and 8 mg/kg against MRSA-494 ranged from 10.4 to 42.2. The targeted ...
Daptomycin binding proteins (DBPs) are membrane proteins which act as daptomycin targets. Daptomycin is a cyclic lipopeptide antibiotic which is active against Gram-positive bacteria and was shown to be the first inhibitor of lipoteichoic acid (LTA) synthesis. It was found that the antibiotic did not penetrate the bacterial cytoplasm but bound membranes with a non-covalent bond and in particular some proteins which were called DBPs. DBPs were indicated as enzymes involved in LTA synthesis whose binding and inhibition by daptomycin is responsible for the observed effect on bacterial LTA synthesis. The purification of DBPs will make it possible not only to shed light on the biosynthesis of the cell wall polymer but will also provide innovative targets for selection of new antibacterial compounds. In this study, the purification of DBPs is described. Affinity chromatography was used with daptomycin as the ligand. Final elution of DBPs from daptomycin-coupled resin was performed using either 0.1% SDS or 3 M
5 Children , 3months and , 16 years with Gram-positive meningitis will receive a single dose of daptomycin 24 hours after the first dose of ceftriaxone. 4-8 hours after daptomycin administration a second lumbar puncture is performed to determine the peak concentration of daptomycin in the cerebrospinal fluid. In parallel peak and trough level of daptomycin will be measured in the plasma. The investigators anticipate that daptomycin penetrates into the cerebrospinal fluid in bactericidal ...
OUTLINE: This is an open-label, pilot study.. Patients first receive standard treatment for gram-negative bacteria for 72 hours. If the patient is still febrile at 72 hours, daptomycin is administered.. Patients receive daptomycin IV over 30 minutes once daily. Patients who are afebrile, not neutropenic (absolute neutrophil count [ANC] , 500/mm³), and have no signs of infection after 72 hours of therapy may discontinue daptomycin. Patients who are afebrile and neutropenic (ANC , 500/mm³) after 72 hours of therapy continue to receive daptomycin until absolute neutrophil count (ANC) , 500/mm³ for 2 consecutive days. Patients who are febrile with or without continued neutropenia (ANC , 500/mm³) after 72 hours of therapy continue to receive daptomycin for up to 10-14 days in the absence of unacceptable toxicity.. PROJECTED ACCRUAL: A total of 30 patients will be accrued for this study. ...
Objectives: In a prospective, randomized trial, daptomycin was non-inferior to standard therapy for Staphylococcus aureus bacteraemia and right-sided endocarditis. Since rates of infection due to methicillin-resistant S. aureus (MRSA) infection are increasing and treatment outcomes for bacteraemia caused by MRSA are generally worse than those observed with methicillin-susceptible S. aureus bacteraemia, clinical characteristics and treatment results in the trials pre-specified subset of patients with MRSA were analysed. Methods: Clinical characteristics and outcomes of patients receiving daptomycin were compared with those receiving vancomycin plus low-dose gentamicin. Success was defined as clinical improvement with clearance of bacteraemia among patients who completed adequate therapy, received no potentially effective non-study antibiotics and had negative blood cultures 6 weeks after end of therapy. Results: Twenty of the 45 (44.4%) daptomycin patients and 14 of the 43 (32.6%) ...
Context: Daptomycin is the only antibiotic available with in vitro bactericidal activity against vancomycin-resistant enterococci (VRE). Its increased use has resulted in cases of decreased daptomycin efficacy. Recent in vitro studies have shown effective use of beta (beta)-lactam and daptomycin antibiotics, as a combination therapy, in the treatment of VRE. We describe a case of effective treatment in a patient with VRE infection using dual ampicillin and daptomycin therapy that shows bench-to-bedside application of the abovementioned finding. Case Report: A 76-year-old gentleman with a history of bilateral arthroplasty was admitted with a swollen left knee. Blood cultures were positive for Enterococcus faecium. Left knee joint aspiration showed leukocytosis and alpha defensins. Extensive imaging did not show any other source of infection. Culture sensitivity results showed multidrug-resistant enterococci sensitive to daptomycin. The patient was started on intravenous (IV) daptomycin. His left ...
The aim of the present study was to compare the potential of ceftobiprole, dalbavancin, daptomycin, tigecycline, linezolid and vancomycin to achieve their requisite pharmacokinetic/pharmacodynamic (PK/PD) targets against methicillin-resistant Staphylococcus aureus isolates collected from intensive care unit (ICU) settings. Monte Carlo simulations were carried out to simulate the PK/PD indices of the investigated antimicrobials. The probability of target attainment (PTA) was estimated at minimum inhibitory concentration values ranging from 0.03 to 32 μg/mL to define the PK/PD susceptibility breakpoints. The cumulative fraction of response (CFR) was computed using minimum inhibitory concentration data from the Canadian National Intensive Care Unit study. Analysis of the simulation results suggested the breakpoints of 4 μg/mL for ceftobiprole (500 mg/2 h t.i.d.), 0.25 μg/mL for dalbavancin (1000 mg), 0.12 μg/mL for daptomycin (4 mg/kg q.d. and 6 mg/kg q.d.) and tigecycline (50 mg b.i.d.), and 2 ...
Daptomycin (DAP) is a cyclic lipopeptide antibiotic used to treat complicated skin and skin structure infections caused by Staphylococcus aureus or enterococci. In addition, it has been approved to treat S. aureus-induced bacteremia and infective endocarditis (21), and animal model studies suggest that it may be a useful alternative for treatment of inhalational anthrax (26). The mechanism of action involves the calcium-dependent insertion of DAP into the bacterial membrane, followed by depolarization of the membrane and extrusion of potassium ions, leading to arrest of macromolecular synthesis and to cell death (49, 51).. The introduction of new antibacterial compounds seems to be followed inevitably by the emergence of resistant isolates. It is estimated that over 1 million patients have been treated with DAP (J. Silverman, personal communication). According to the SENTRY Antimicrobial Surveillance Program in the United States for the years 2002 to 2010, 99.9% of methicillin-resistant S. ...
Even with prompt treatment, Staphylococcus aureus Infective Endocarditis (IE) continues to be associated with significant morbidity and mortality indicating a need for new therapeutic approaches. In vitro, daptomycin is rapidly bactericidal, with concentration-dependent killing, and MIC90 of 0.5 g/ml for S. aureus; in clinical studies, daptomycin appears to be well tolerated and can be administered once every 24 hours by i.v. infusion. These characteristics suggest it should be clinically and microbiologically effective in the treatment of serious S. aureus infections, including IE and bacteremia. ...
Dependence on antimicrobial agents to treat simple to extremely complex illnesses is ever growing and thus so is bacterial antibiotic resistance. Due to this it is integral to truly understand, on a molecular level how an antibiotics kills a target cell. By understanding the mode of action of an antibiotic, it could not only mean that the drug could be better used in regards to usage and the infections it should be used against, but also give an insight into potential novel antibiotics. Whilst antibiotics kill or prevent growth of bacteria via different several methods; all antibiotics must meet and cross the bacterial membrane meaning understanding this interaction is vital. This is especially true in cases where the antimicrobial kills cells by disrupting the cell membrane, such as with daptomycin and chlorhexidine focused upon in this project. Whilst daptomycin is an antibiotic, which works on specifically gram-positive bacteria, such as Staphylococcus aureus, chlorhexidine not targets both ...

Results: A total of 332 daptomycin plasma concentrations were determined in 86 patients. 66% (n=218) of all determinations were trough concentrations (Cmin) and 34% (n=114) were peak concentrations (Cmax). Cmin ranged 2-68mg/L (median 16.7mg/L) and Cmax 20-236mg/L (median 66.2mg/L). A significant positive association of total dose, albumin, creatinine, and a significant negative association of dose interval and intermittent haemodialysis with Cmin was found in the regression analysis. Total dose and Intensive Care Unit (ICU)_-stay was significantly associated with Cmax (P,0.05). However, only 28% (P,0.005) of Cmin variability and 8% (P=0.08) of Cmax variability was explained by the factors included in the analysis ...

The bactericidal activities of daptomycin, vancomycin, teicoplanin and linezolid at human peak free serum concentrations (C(max,free)) were determined against Staphylococcus aureus (one methicillin-susceptible and two methicillin-resistant strains), Enterococcus faecalis and Enterococcus faecium (one vancomycin-susceptible and one vancomycin-resistant strain of each). Daptomycin was rapidly bactericidal against 7/7 strains at C(max,free) of 22.0 mg/L (corresponding to 63% protein binding) and against 3/7 strains at 4.8 mg/L (corresponding to 92% protein binding). Vancomycin (18.0 mg/L) was bactericidal against only two strains. Both teicoplanin (4.5 mg/L) and linezolid (10.4 mg/L) were consistently bacteriostatic. Daptomycin is a useful option for the treatment of Gram-positive infections owing to its strong bactericidal activity ...

Background: Vancomycin-resistant Enterococcus faecium are difficult nosocomial pathogens to treat. Daptomycin (DAP) is a key front-line bactericidal antibiotic against VRE. Development of DAP resistance during therapy raises concerns about the role of DAP monotherapy in severe enterococcal infections. Limited previous data suggest that ceftaroline (CPT) enhances the in vitro activity of DAP against enterococci. We sought to evaluate the in vivo activity of DAP plus CPT against a DAP-R strain of E. faecium using an experimental infective endocarditis (IE) rat model. Methods: MICs and time-kill assays were performed using standard methods. IE was produced in carotid artery and jugular vein catheterized rats by intracardiac inoculation of 10X the ID90 of E. faecium HOU497. Therapy (3 days, via infusion pump) was begun 24 h after inoculation. Some animals were sacrificed at the time of therapy initiation to evaluate bacterial loads (T=0). Drug regimens included i) CPT, 30 min, 40 mg/kg q8h, ii) DAP, ...
Complicated skin and soft tissue infections: literature review of evidence for and experience with daptomycin Beth White, R Andrew SeatonBrownlee Center, Gartnavel General Hospital, Glasgow, ScotlandAbstract: Skin and soft tissue infections (SSTIs) are the second most common infection encountered in hospitals. Management decisions have become increasingly complex due to the prevalence of resistant pathogens, the wide array of licensed antimicrobials and the availability of potent oral agents and of out-patient parenteral antibiotic therapy. Daptomycin is one of the newer therapeutic agents licensed for complex SSTI management. Rapid cidality, good soft tissue penetration, once daily IV bolus administration and activity against resistant Gram-positive infections make daptomycin an attractive option both in hospitalized and community treated patients. A comprehensive review of the evidence for and experience with daptomycin and its use in SSTIs is presented.Keywords: SSTI, MRSA, OPAT, outpatient
Lien vers Pubmed [PMID] - 23700464. PLoS ONE 2013;8(5):e64218. Enterococcus faecalis (E. faecalis) has become a major leading cause of nosocomial endocarditis. Treatment of such infections remains problematic and new therapeutic options are needed. Nine E. faecalis strains were tested: six obtained from patients presenting endocarditis, one with isolated bacteremia, and two reference strains. Antibiotics included daptomycin, alone or in combination, linezolid, tigecycline, rifampicin, gentamicin, teicoplanin, ceftriaxone and amoxicillin. Time-kill studies included colony counts at 1, 4 and 24 h of incubation. Significant bactericidal activity was defined as a decrease of ≥3log10CFU/ml after 24 h of incubation. Antibiotics were tested at a low (10(6) CFU/ml) and high (10(9) CFU/ml) inoculum, against exponential- and stationary-phase bacteria. We also performed time kill studies of chemically growth arrested E. faecalis. Various pH conditions were used during the tests. In exponential growth ...

Having a background in both Biology and Physics, working in Dr. Zoya Leonenkos Nanoscale Biophysics Group is the perfect marriage for both my passions. I get to use methods and theories from physics to study a biological issue on the nanoscale. To study the effect of daptomycin on bacterial membrane and lung surfactant lipid models, I use atomic force microscopy (Figure 3) or AFM to observe any structural changes that take place in the presence of daptomycin by taking images of the samples surface. To understand how AFM works, imagine that the AFM has a tip that is comparable to the needle of a record player and that the sample surface is like the vinyl record. This tip runs back and forth along the sample surface, experiencing attractive and repulsive ...
Carbapenems are a class of beta-lactam classes of drugs which include penicillins, cephalosporins,. cephamycins and carbapenems. These antibiotics have a common element in. their molecular structure: a four-atom ring known as a beta-lactam. The. lactamase enzyme breaks that ring open, deactivating the molecules. antibacterial properties.. Jones also noted that current susceptibility patterns of newer antimicrobial drugs goes up every year, especially with drugs such as Vancomycin and Daptomycin MIC, a glycopeptide antibiotic and a novel lipopeptide antibiotic respectively, used in the prophylaxis and treatment of infections caused by Gram-positive bacteria..

Owing to their massive use, Staphylococcus epidermidis has recently developed significant resistance to several antibiotics, and became one of the leading causes of hospital-acquired infections. Current antibiotics are typically ineffective in the eradication of bacteria in biofilm-associated persistent infections. Accordingly, the paucity of effective treatment against cells in this mode of growth is a key factor that potentiates the need for new agents active in the prevention or eradication of biofilms. Daptomycin and linezolid belong to the novel antibiotic therapies that are active against gram-positive cocci. on the other hand, rifampicin has been shown to be one of the most potent, prevalent antibiotics against S. epidermidis biofilms. Therefore, the main aim of this study was to study the susceptibility of S. epidermidis biofilm cells to the two newer antimicrobial agents previously mentioned, and compare the results obtained with the antimicrobial effect of rifampicin, widely used in ...
Brilacidin (PMX30063) has shown potent bactericidal activity against drug-resistant and -susceptible strains of multiple Gram-negative and Gram-positive pathogens. In this study, we demonstrate that brilacidin causes membrane depolarization in the Gram-positive bacterium Staphylococcus aureus, to an extent comparable to that caused by the lipopeptidic drug daptomycin. Transcriptional profiling of Staphylococcus aureus by deep sequencing shows that the global response to brilacidin treatment is well correlated to those of treatment with daptomycin and the cationic antimicrobial peptide LL37 and mostly indicates abrogation of cell wall and membrane functions ...
