OBJECTIVE: Higher vancomycin concentrations are thought necessary for treatment of deep-seated methicillin-resistant Staphylococcus aureus (MRSA) infection, yet this may result in greater risk of nephrotoxicity. We evaluated the relationship of serum vancomycin trough concentration with clinical outcomes and nephrotoxicity for patients with deep-seated MRSA infection.. METHODS: A retrospective cohort study evaluated adults with MRSA pneumonia, endocarditis or osteomyelitis who received vancomycin for , or = 5 days from June 2005 to June 2007. Patients were stratified by mean vancomycin trough level [low (, 15 mg/l), high (, or = 15 mg/l)]. Outcomes were clinical response, mortality, length of stay (LOS) and nephrotoxicity. Three definitions of nephrotoxicity were used: i) rise in serum creatinine (SCr) , or = 0.5 mg/dl; ii) 50% increase in SCr; and iii) 25% decrease in estimated creatinine clearance.. RESULTS: Fifty-five patients experiencing MRSA pneumonia (n = 28), endocarditis (n = 9), ...
Vancomycin Hydrochloride with NDC 70594-047 is a a human prescription drug product labeled by Xellia Pharmaceuticals Usa Llc. The generic name of Vancomycin Hydrochloride is vancomycin hydrochloride.
STUDY OBJECTIVES: To determine if a higher serum vancomycin (Vt) target trough concentration of 15-20 μg/ml or greater is associated with an increased rate of vancomycin-induced nephrotoxicity in children admitted to a pediatric intensive care unit (PICU), and to determine risk factors for developing vancomycin-induced nephrotoxicity.. DESIGN: Retrospective cohort study.. SETTING: A PICU within a freestanding tertiary care pediatric hospital.. PATIENTS: A total of 113 patients received vancomycin for at least 48 hours The high-trough cohort (H group [57 patients]) received vancomycin therapy between November 2008 and June 2009 for pneumonia, bacteremia, or meningitis that was managed by a clinical pharmacist who directed dosage adjustments driven by a novel algorithm to attain a target Vt concentration of 15-20 μg/ml or greater; the control group (C group [56 patients]) received vancomycin therapy during the preceding 10 months (between January and October 2008) for pneumonia or meningitis ...
Peak and Trough Guide. 1. Peak & Trough Vancomycin is a glycopeptide antibiotic. It is a time dependent killer. The level has to stay above a minimum concentration for a length of time for the medication to be effective. Thus, Vancomycin doses should not be held while waiting for a trough level. Vancomycin peak levels are not routinely monitored, however if ordered by the MD, the peak should be drawn 1 hour after medication dose is complete. Exception - if the ordered dose of Vancomycin is 2 grams or more then obtain the peak 2 hours after the infusion is complete.. 2. Peak & Trough (cont) Collect trough immediately prior to dose Blood must NOT be drawn from the line it was infusing in Blood is drawn from a different port, it is NOT drawn from the port it was infused in Do not draw a trough level while Vancomycin is infusing Do not wait for trough results before hanging antibiotic unless a specific order to wait for result is ordered by MD Administer antibiotic at prescribed rate so levels are ...

Patients admitted into the Intensive Care Unit (ICU) have an intravenous (IV) catheter (small plastic tube) placed in their vein. Very occasionally (4 times out of 100) the insertion of an intravenous catheter may cause an infection in the blood. It has been shown that the removal of the catheter and the insertion of a new one at a new site helps to get rid of this infection. Sometimes, antibiotics are also given.. Vancomycin is the antibiotic given intravenously (into the vein) to treat these catheter-related infections. At Vancouver General Hospital, some physicians may not give any vancomycin at all whereas others may treat with intravenous (IV) vancomycin for one to fourteen days.. Since there are a lack of data to support the length of IV vancomycin therapy, the investigators would like to find out if two days of IV vancomycin are as good as seven days.. Therefore, the purpose of this study is to determine if two days of IV vancomycin are as good as seven days for the treatment of ...
Vancomycin-resistant Enterococcus, or vancomycin-resistant enterococci (VRE), are bacterial strains of the genus Enterococcus that are resistant to the antibiotic vancomycin. Six different types of vancomycin resistance are shown by enterococcus: Van-A, Van-B, Van-C, Van-D, Van-E and Van-G. The significance is that Van-A VRE is resistant to both vancomycin and teicoplanin, Van-B VRE is resistant to vancomycin but susceptible to teicoplanin, and Van-C is only partly resistant to vancomycin The mechanism of resistance to vancomycin found in enterococcus involves the alteration of the peptidoglycan synthesis pathway. The D-alanyl-D-lactate variation results in the loss of one hydrogen-bonding interaction (four, as opposed to five for D-alanyl-D-alanine) being possible between vancomycin and the peptide. The D-alanyl-D-serine variation causes a six-fold loss of affinity between vancomycin and the peptide, likely due to steric hindrance. Once the individual has VRE, it is important to ascertain which ...
The increased vancomycin minimum inhibitory concentration values (MICs) for methicillin-resistant Staphylococcus aureus (MRSA) isolates are associated with treatment failure and mortality of MRSA infections. In the present study, 553 non-duplicate MRSA isolates from various specimens of patients with infections at a Chinese tertiary hospital from January 2003 to December 2014, were selected randomly for investigating the shift of vancomycin MICs determined by E-test method. The percentages of the MRSA isolates with vancomycin MICs of ≥ 2.0 mg/L, 1.5 mg/L, 1.0 mg/L and ≤0.75 mg/L were 16.3% (90/553), 38.5% (213/553), 35.6% (197/553) and 9.9% (55/553), respectively. The highest geometric mean MIC (GM MIC) value (1.648 mg/L) and the lowest GM MIC (0.960 mg/L) were found in the first year (2003) and the last year (2014) over the study period, with significant difference (p
Obesity alters the movement through the body of several antibiotics, including vancomycin. Based on literature to date, total body weight should be used to determine dosages and shorter dosing intervals may be needed. However, hospitals have different approaches to managing vancomycin in this patient population. The most common example is not exceeding a dose of 2,000mg of vancomycin at one time in these patients. However, some institutions including the Charleston Area Medical Center do not have a set maximum one time dose. To date, a study has not been done comparing two different dosing regimens in obese patients to determine if having a maximum dose cap is beneficial.. This research study is attempting to add to the limited existing body of literature regarding vancomycin dosing in obese patients. The investigators hypothesize that optimizing the initial or loading vancomycin dose that obese patients receive will decrease the time to target concentrations. For this study, obese adult ...
Purpose: To develop a sustained delivery system to improve the release kinetics of vancomycin as well as its therapeutic effectiveness to prevent postoperative corneal infection.. Methods: Vancomycin was incorporated into an engineered collagen hydrogel (10 and 15 wt%) scaffold through N-ethyl-N-[3-dimethylaminopropyl] carbodiimide/N-hydroxy succinimide (EDC/NHS) crosslinking technique. Vancomycin incorporation into the collagen hydrogel was examined by fourier transform infrared spectroscopy (FTIR) and quantified spectrophotometrically after collagen digestion with collagenase. Mechanical stability of hydrogel was measured by Instron instrument. In vitro release profile of vancomycin was measured in PBS at 37°C. Structural integrity of released vancomycin was assessed by circular dichroism (CD) spectroscopy. The minimum inhibitory concentration (MIC) of control and released vancomycin against S.aureus (SA) was determined by inoculating with bacterial suspension (106 colony-forming unit/ml). ...

Borrelia burgdorferi, the agent of Lyme disease, and B. turicatae, a neurotropic agent of relapsing fever, are susceptible to vancomycin in vitro, with an MIC of 0.5 microgram/ml. To determine the activity of vancomycin in vivo, particularly in the brain, we infected adult immunocompetent BALB/c and immunodeficient CB-17 scid mice with B. burgdorferi or B. turicatae. The mice were then treated with vancomycin, ceftriaxone as a positive control, or normal saline as a negative control. The effectiveness of treatment was assessed by cultures of blood and brain and other tissues. Ceftriaxone at a dose of 25 mg/kg of body weight administered every 12 h for 7 to 10 days eliminated cultivable B. burgdorferi or B. turicatae from all BALB/c or scid mice in the study. Vancomycin at 30 mg/kg administered every 12 h was effective in eliminating infection from immunodeficient mice if treatment was started within 3 days of the onset of infection. If treatment with vancomycin was delayed for 7 days or more, ...
Laboratory Detection of Vancomycin ResistanceVancomycin resistance can be difficult to detect in the clinical microbiology laboratory. Disk diffusion sensitivity testing using the standard 30-μg vancomycin disk frequently misclassifies intermediately susceptible isolates as fully susceptible (70). In a recent study, 75% of microbiology laboratories from around the world misreported a glycopeptide-intermediate strain of Staphylococcus epidermidis as susceptible based on the results of disk diffusion testing (71).. Automated testing methods like MicroScan rapid panels (Dade Behring) and Vitek (version 7.07; bioMerieux) also have pitfalls. While conventional MicroScan panels performed well in detecting reduced susceptibilities to vancomycin, the rapid panels are less reliable as they do not allow for the recommended 24-h incubation (14, 70). Prior to 1999, Vitek software was not programmed to report vancomycin MICs above 4 μg/ml and would thus report the MICs of intermediately susceptible or ...

Interestingly, we have been unable to find a textbook or reference that properly accounts for drug elimination during the infusion period. Popular textbooks like Applied Clinical Pharmacokinetics (Bauer), Basic Clinical Pharmacokinetics (Winter), Applied Pharmacokinetics (Evans), Applied Biopharmaceutics & Pharmacokinetics (Shargel), and Handbook of Basic Pharmacokinetics (Ritschel) just dont address this phenomenon.. Why wouldnt these textbooks address elimination during infusion? The most likely reason is that vancomycin is doses very differently today than a decade or two ago. Historically, vancomycin doses and dosing frequencies were much lower. With the ASHP/IDSA/SIDP vancomycin recommendations targeting trough levels of 15-20 mcg/mL and the obesity epidemic, were giving larger doses more frequently than ever before.. Because of these larger doses, drug elimination during the infusion actually matters. With lower doses or less frequent administration, accounting for drug elimination ...
Fifty-six methicillin-resistant Staphylococcus aureus clinical isolates were collected over a two-month period from a large teaching hospital in Pretoria, South Africa. Isolates were subjected to screening and confirmatory testing for vancomycin hetero-resistance. Thirty-three isolates were identified with the macro-method Etest as possibly being hetero-resistant to vancomycin. Twenty randomly selected hetero-resistant isolates were subjected to population analysis profile, area under the curve ratio methodology, of which 18 were confirmed to be vancomycin hetero-resistant. As a screening test, the macro-method Etest thus exhibited high sensitivity and specificity, for detecting hetero-resistant S. aureus at this institution.
Staphylococcus aureus has remained one of the most frequent causes of a wide range of both hospital- and community-acquired infections, from superficial skin and other soft tissue infections to life threatening toxic shock, pneumonia, endocarditis, and septicemia. The spectacular adaptive capacity of this pathogen resulted in the emergence and worldwide spread of lineages that acquired resistance to the majority of available antimicrobial agents. The choice of therapy against such multidrug-resistant S. aureus (MRSA) strains has been narrowed to a few antibacterial agents, among them the glycopeptide antibiotic vancomycin, which has become the mainstay of therapy worldwide. MRSA strains with reduced susceptibility to vancomycin have been reported in clinical specimen since the late 1990s (1). In most of these so-called vancomycin intermediate-resistant S. aureus (VISA) isolates, decrease in drug susceptibility, as expressed by the increase in the minimal inhibitory concentration (MIC) of ...
Treatment factors predictive of clinical and microbiological outcomes and the relationship between a pneumonia scoring system and clinical outcomes in vancomycin-treated patients with a Staphylococcus aureus-associated lower-respiratory-tract infection (LRTI) were studied. A computer database review identified patients for whom S. aureus was isolated from a respiratory-tract specimen between January 1 and December 31, 1998, and who had antimicrobials ordered within 72 hours of isolation of that organism. Through further review of individual patient charts, this group was restricted to those treated with vancomycin for a documented S. aureus-associated LRTI. Classification-and-regression-tree (CART) modeling was performed to determine which clinical variables were correlated with clinical outcomes and microbiological outcomes. Median changes in clinical pneumonia scores from baseline in two patient groups (those with clinical success and those with clinical failure) were compared. Seventy patients met
In neurosurgery, surgical site infections are major cause of morbidity and mortality. It has been significant burden in clinical practice, despite of best practices with or without use of antibiotics. Topical antibiotics are one potential method reducing the problem. In our study, we seek to evaluate the benefits of topical vancomycin. In this Institutional Review Board-approved retrospective observational study, patients who underwent neurosurgical intervention in Department of Neurological Surgery KMCTH enrolled retrospectively from October 1, 2014 to September 30, 2018. Patients in whom topical vancomycin powder applied intra operatively for post operative SSI prophylaxis and those without, comprising the vast majority of neurosurgical patients within the KMCTH, were examined. Patients presenting with infection, open wound, multiple scheduled surgeries, application of topical antibiotics other than vancomycin, or multiple antibiotics were excluded. Patients data were analyzed within the first ...
This study is a collaboration between NYP-Columbia and NYP-Cornell that seeks to evaluate the use of topical vancomycin and its reduction on surgical site infection (SSI) in neurosurgical procedures. Adult patients undergoing neurosurgery at either institution will be eligible for participation in this randomized control trial. Patients randomized to the treatment group will receive 2g of vancomycin applied as a powder or paste to the wound site and/or bone flap. Subjects in the control group will receive the current standard of care without topical vancomycin. All subjects will undergo swabbing of the anterior nares and the surgical site prior to surgery, once 10-14 days following the operation and 90 days following the operation. The primary outcome measure will be surgical site infection, assessed daily throughout the hospital stay, at the first follow-up visit, and by telephone at 30 days. Secondary outcomes will include length of hospital

OBJECTIVES: To develop a population pharmacokinetic (PK) model for vancomycin in Chinese neonates and infants less than 2 months of age (young infants) with a wide gestational age range, in order to determine the appropriate dosing regimen for this population. METHODS: We performed a retrospective chart review of patients from the neonatal intensive care unit (NICU) at Childrens Hospital of Fudan University to identify neonates and young infants treated with vancomycin from May 2014 to May 2017. Vancomycin concentrations and covariates were utilized to develop a one-compartment model with first-order elimination. The predictive performance of the final model was assessed by both internal and external evaluation, and the relationship between trough concentration and AUC0-24 was investigated. Monte Carlo simulations were performed to design an initial dosing schedule targeting an AUC0-24 ,/= 400. RESULTS: The analysis included a total of 330 concentration-time data points from 213 neonates and ...

To the editor: Allergic reactions to vancomycin are not rare and can be serious when a patient is infected by an organism (usually staphylococci) for which there is no satisfactory alternate antibiotic agent (1, 2). We report the case of a woman infected with a methicillin-resistant Staphylococcus aureus who was twice successfully hyposensitized to vancomycin after she had a severe systemic allergic reaction to the drug.. Our 36-year-old patient had a history of recurrent staphylococcal skin abscesses since childhood. She presented with a chronic, subcutaneous infection of her right elbow and a breast abscess. Both wounds contained methicillin-resistant S. aureus ...
Despite the emergence of glycopeptide insensitivity and resistance triggered through years of widespread use of glycopeptide antibiotics, vancomycin remains the mainstay treatment for MRSA infections.2 Although total resistance to vancomycin in S. aureus is still rare (VRSA), the increased incidence of infections caused by MRSA strains that display subtle reductions in susceptibility has dramatically increased (hVISA); such infections correlate with treatment failure and increased mortality.3 S. aureus strains of this nature arise in the hospital setting during failed prolonged glycopeptide therapy, particularly for patients with high bacterial load infections (e.g. endocarditis, osteomyelitis/septic arthritis, deep abscesses, infection of prosthetic devices) and/or history of prior vancomycin exposure. Vancomycin, which is dosed intravenously, has relatively poor pharmacokinetic properties, including a short half-life and poor tissue penetrating properties. The inability of vancomycin to fully ...
Oxidative phenol cross-linking reactions play a key role in the biosynthesis of glycopeptide antibiotics such as vancomycin. The vancomycin aglycone contains three cross-links between aromatic amino acid side-chains, which stabilize the folded backbone conformation required for binding to the target D-Ala-D-Ala dipeptide. At least the first cross-link is introduced into a peptide precursor whilst it is still bound as a thioester to a peptide carrier protein (PCP) domain (also called a thiolation domain) within the nonribosomal peptide synthetase. We described here methods for the solid-phase synthesis of peptides and their coupling to PCP domains, which may be useful for in vitro studies of cross-linking and related tailoring reactions during nonribosomal glycopeptide antibiotic biosynthesis. ...

Read: 84-Page Report Outlines 9 Ways to Beat Antibiotic Resistance. Researchers used sensitive equipment to measure mechanical forces that 4 different antibiotics exerted on bacterial cells, according to a news release. They tested bacteria that were particularly susceptible to antibiotics and bacteria that had become resistant to drugs. The forces the antibiotics exerted on susceptible bacteria were all similar, but the forces exerted by the drugs on resistant antibiotics varied greatly.. The team tested vancomycin, a powerful antibiotic used as a last resort treatment for MRSA and other infections, and oritavancin, a modified version of vancomycin used against complex skin infections.. Oritavancin is fast-acting antibiotic compared to vancomycin, killing bacteria in 15 minutes and 6-24 hours, respectively. Vancomycin disrupts vital processes in bacteria, causing them to slowly stop functioning and die. Oritavancin is technically a modified version of vancomycin, but the new study suggests that ...
