Emergence of vancomycin resistance in Staphylococcus aureus. Glycopeptide-Intermediate Staphylococcus aureus Working Group. (1/2494)

BACKGROUND: Since the emergence of methicillin-resistant Staphylococcus aureus, the glycopeptide vancomycin has been the only uniformly effective treatment for staphylococcal infections. In 1997, two infections due to S. aureus with reduced susceptibility to vancomycin were identified in the United States. METHODS: We investigated the two patients with infections due to S. aureus with intermediate resistance to glycopeptides, as defined by a minimal inhibitory concentration of vancomycin of 8 to 16 microg per milliliter. To assess the carriage and transmission of these strains of S. aureus, we cultured samples from the patients and their contacts and evaluated the isolates. RESULTS: The first patient was a 59-year-old man in Michigan with diabetes mellitus and chronic renal failure. Peritonitis due to S. aureus with intermediate resistance to glycopeptides developed after 18 weeks of vancomycin treatment for recurrent methicillin-resistant S. aureus peritonitis associated with dialysis. The removal of the peritoneal catheter plus treatment with rifampin and trimethoprim-sulfamethoxazole eradicated the infection. The second patient was a 66-year-old man with diabetes in New Jersey. A bloodstream infection due to S. aureus with intermediate resistance to glycopeptides developed after 18 weeks of vancomycin treatment for recurrent methicillin-resistant S. aureus bacteremia. This infection was eradicated with vancomycin, gentamicin, and rifampin. Both patients died. The glycopeptide-intermediate S. aureus isolates differed by two bands on pulsed-field gel electrophoresis. On electron microscopy, the isolates from the infected patients had thicker extracellular matrixes than control methicillin-resistant S. aureus isolates. No carriage was documented among 177 contacts of the two patients. CONCLUSIONS: The emergence of S. aureus with intermediate resistance to glycopeptides emphasizes the importance of the prudent use of antibiotics, the laboratory capacity to identify resistant strains, and the use of infection-control precautions to prevent transmission.  (+info)

Isolation and chemical characterization of a capsular polysaccharide antigen shared by clinical isolates of Enterococcus faecalis and vancomycin-resistant Enterococcus faecium. (2/2494)

Enterococci are a common cause of serious infections, especially in newborns, severely immunocompromised patients, and patients requiring intensive care. To characterize enterococcal surface antigens that are targets of opsonic antibodies, rabbits were immunized with various gentamicin-killed Enterococcus faecalis strains, and immune sera were tested in an opsonophagocytic assay against a selection of clinical isolates. Serum raised against one strain killed the homologous strain (12030) at a dilution of 1:5,120 and mediated opsonic killing of 33% of all strains tested. In addition, this serum killed two (28%) of seven vancomycin-resistant Enterococcus faecium strains. Adsorption of sera with the homologous strain eliminated killing activity. The adsorbing antigens were resistant to treatment with proteinase K and to boiling for 1 h, but were susceptible to treatment with sodium periodate, indicating that the antigen inducing opsonic activity is a polysaccharide. Antibodies in immune rabbit sera reacted with a capsule-like structure visualized by electron microscopy both on the homologous E. faecalis strain and on a vancomycin-resistant E. faecium strain. The capsular polysaccharides from E. faecalis 12030 and E. faecium 838970 were purified, and chemical and structural analyses indicated they were identical glycerol teichoic acid-like molecules with a carbohydrate backbone structure of 6-alpha-D-glucose-1-2 glycerol-3-PO4 with substitution on carbon 2 of the glucose with an alpha-2-1-D-glucose residue. The purified antigen adsorbed opsonic killing activity from immune rabbit sera and elicited high titers of antibodies (when used to immunize rabbits) that both mediated opsonic killing of bacteria and bound to a capsule-like structure visualized by electron microscopy. These results indicate that approximately one-third of a sample of 15 E. faecalis strains and 7 vancomycin-resistant E. faecium strains possess shared capsular polysaccharides that are targets of opsonophagocytic antibodies and therefore are potential vaccine candidates.  (+info)

Infective endocarditis due to Staphylococcus aureus: 59 prospectively identified cases with follow-up. (3/2494)

Fifty-nine consecutive patients with definite Staphylococcus aureus infective endocarditis (IE) by the Duke criteria were prospectively identified at our hospital over a 3-year period. Twenty-seven (45.8%) of the 59 patients had hospital-acquired S. aureus bacteremia. The presumed source of infection was an intravascular device in 50.8% of patients. Transthoracic echocardiography (TTE) revealed evidence of IE in 20 patients (33.9%), whereas transesophageal echocardiography (TEE) revealed evidence of IE in 48 patients (81.4%). The outcome for patients was strongly associated with echocardiographic findings: 13 (68.4%) of 19 patients with vegetations visualized by TTE had an embolic event or died of their infection vs. five (16.7%) of 30 patients whose vegetations were visualized only by TEE (P < .01). Most patients with S. aureus IE developed their infection as a consequence of a nosocomial or intravascular device-related infection. TEE established the diagnosis of S. aureus IE in many instances when TTE was nondiagnostic. Visualization of vegetations by TTE may provide prognostic information for patients with S. aureus IE.  (+info)

Molecular diversity and evolutionary relationships of Tn1546-like elements in enterococci from humans and animals. (4/2494)

We report on a detailed study on the molecular diversity and evolutionary relationships of Tn1546-like elements in vancomycin-resistant enterococci (VRE) from humans and animals. Restriction fragment length polymorphism (RFLP) analysis of the VanA transposon of 97 VRE revealed seven different Tn1546 types. Subsequent sequencing of the complete VanA transposons of 13 VRE isolates representing the seven RFLP types followed by sequencing of the identified polymorphic regions in 84 other VanA transposons resulted in the identification of 22 different Tn1546 derivatives. Differences between the Tn1546 types included point mutations in orf1, vanS, vanA, vanX, and vanY. Moreover, insertions of an IS1216V-IS3-like element in orf1, of IS1251 in the vanS-vanH intergenic region, and of IS1216V in the vanX-vanY intergenic region were found. The presence of insertion sequence elements was often associated with deletions in Tn1546. Identical Tn1546 types were found among isolates from humans and farm animals in The Netherlands, suggesting the sharing of a common vancomycin resistance gene pool. Application of the genetic analysis of Tn1546 to VRE isolates causing infections in Hospitals in Oxford, United Kingdom, and Chicago, Ill., suggested the possibility of the horizontal transmission of the vancomycin resistance transposon. The genetic diversity in Tn1546 combined with epidemiological data suggest that the DNA polymorphism among Tn1546 variants can successfully be exploited for the tracing of the routes of transmission of vancomycin resistance genes.  (+info)

Synergy of an investigational glycopeptide, LY333328, with once-daily gentamicin against vancomycin-resistant Enterococcus faecium in a multiple-dose, in vitro pharmacodynamic model. (5/2494)

The pharmacodynamics of an investigational glycopeptide, LY333328 (LY), alone and in combination with gentamicin, against one vancomycin-susceptible and two vancomycin-resistant Enterococcus faecium strains were studied with a multiple-dose, in vitro pharmacodynamic model (PDM). Dose-range data for the PDM studies were obtained from static time-kill curve studies. In PDM experiments conducted over 48 h, peak LY concentrations of 0.1x and 1x the MIC every 24 h and peak gentamicin concentrations of 18 micrograms/ml every 24 h (Gq24 h) and 6 micrograms/ml every 8 h (Gq8 h) were studied alone and in the four possible LY-gentamicin combinations. Compared to either antibiotic alone, LY-gentamicin combination regimens produced significantly higher apparent killing rates (KRs) calculated during the initial 2 h postdosing. The mean KRs for LY or gentamicin alone versus those for the LY-gentamicin combination regimens were 0.35 +/- 0.55 log10 CFU/ml/h (95% confidence interval [CI95%], 0 to 0.70) and 1.46 +/- 0.71 log10 CFU/ml/h (CI95%, 1.01 to 1.91), respectively (P < 0.0001). Bacterial killing at 48 h (BK48), which was calculated by subtracting the bacterial counts at 48 h from the initial inoculum, with a negative value indicating net growth, was also significantly greater. The mean BK48S were -0.69 +/- 0.44 log10 CFU/ml (CI95%, -0.41 to -0.97) and 3.72 +/- 2.28 log10 CFU/ml (CI95%, 2.28 to 5.17) for LY or gentamicin alone versus LY-gentamicin combination regimens, respectively (P < 0.0001). None of the 12 regimens with LY or gentamicin alone but 75% (9 of 12) of the LY-gentamicin combination regimens were bactericidal. Eighty-three percent (10 of 12) of the LY-gentamicin combination regimens also demonstrated synergy. No significant differences between the pharmacodynamics of LY-gentamicin combination regimens containing Gq24 h versus those containing Gq8h were detected.  (+info)

Evaluation of bactericidal activities of LY333328, vancomycin, teicoplanin, ampicillin-sulbactam, trovafloxacin, and RP59500 alone or in combination with rifampin or gentamicin against different strains of vancomycin-intermediate Staphylococcus aureus by time-kill curve methods. (6/2494)

This in vitro study evaluated the activities of vancomycin, LY333328, and teicoplanin alone and in combination with gentamicin, rifampin, and RP59500 against Staphylococcus aureus isolates with intermediate susceptibilities to vancomycin. Ampicillin-sulbactam and trovafloxacin were also evaluated. LY333328 and ampicillin-sulbactam resulted in bactericidal activity against all isolates. The combination of gentamicin with glycopeptides showed synergistic activity, while rifampin had no added benefit.  (+info)

Changing susceptibilities of coagulase-negative staphylococci to teicoplanin in a teaching hospital. (7/2494)

The susceptibility of two collections of coagulase-negative staphylococci (CNS) isolated from clinical specimens for teicoplanin and vancomycin were compared. They comprised 91 and 101 isolates, collected in 1985 and 1994 respectively, from different departments of a teaching hospital. MICs of vancomycin and teicoplanin were determined by a modified Etest method. Additionally, a disc diffusion test was performed for teicoplanin. All isolates were susceptible to vancomycin (MIC < or = 4 mg/L). Two of the 91 isolates collected in 1985 were intermediate to teicoplanin (MIC between 8 and 32 mg/L), whereas in 1994 the number of intermediate isolates was 20 out of 101 (P < 0.01). The correlation between MICs, as determined by the modified Etest assay, and disc diffusion zones was poor (r = -0.35). Results show that resistance to teicoplanin in CNS has increased in the study hospital over a period of 9 years. This increase is likely to be correlated with the introduction of teicoplanin. Furthermore, a disc diffusion method does not appear to be the first method of choice for detection of strains of CNS with diminished susceptibility to teicoplanin.  (+info)

Transmission dynamics of epidemic methicillin-resistant Staphylococcus aureus and vancomycin-resistant enterococci in England and Wales. (8/2494)

A simple epidemiological framework for the analysis of the transmission dynamics of hospital outbreaks of epidemic methicillin-resistant Staphylococcus aureus (EMRSA) and vancomycin-resistant enterococci (VRE) in hospitals in England and Wales is presented. Epidemic strains EMRSA-15 and EMRSA-16 are becoming endemic in hospitals in the United Kingdom, and theory predicts that EMRSA-15 and EMRSA-16 will reach respective endemic levels of 158 (95% confidence interval [CI], 143-173) and 116 (95% CI, 109-123) affected hospitals with stochastic fluctuations of up to 30 hospitals in each case. An epidemic of VRE is still at an early stage, and the incidence of hospitals newly affected by VRE is growing exponentially at a rate r=0.51/year (95% CI, 0.48-0.54). The likely impact of introducing surveillance policies if action is taken sufficiently early is estimated. Finally, the role of heterogeneity in hospital size is considered: "Super-spreader hospitals" may increase transmission by 40%-132% above the expected mean.  (+info)

The aim of this study was to evaluate the influence of patient body mass index (BMI) and estimated creatinine clearance (CrCl) on serum vancomycin concentrations to define a possible optimal dosage regimen in overweight patients based on data obtained during therapeutic drug monitoring. This retrospective study used data collected from January 2017 to January 2019. Adult patients (n = 204) received vancomycin treatment at a dose of 1000 mg every 12 h and underwent serum monitoring. Data collected included patient disease category, sex, age, height, weight, vancomycin concentrations, and serum creatinine. The CrCl values were estimated using the Cockcroft-Gault formula. In this study, statistical comparisons were performed on the results of patients according to serum vancomycin concentration. Serum vancomycin concentration was significantly related to BMI (P | 0.001) and CrCl (P | 0.05) in adult patients. Furthermore, the trough serum vancomycin concentration showed a logarithmic correlation with BMI
ABSTRACT. Vancomycin is widely used in the prophylaxis and treatment of infections in neutropenic patients with cancer.. The objective of this study was to analyze liver damage effects on vancomycin pharmacokinetics and determine the necessity for liver function evaluation when selecting vancomycin dosing schedules in these patients. A population pharmacokinetic analysis was performed using the global two-stage method. To this purpose serum vancomycin concentrations from 154 cancer patients were measured and individual vancomycin pharmacokinetic parameters were estimated by the Sawchuk and Zaske method. Mean and standard deviation of the vancomycin pharmacokinetic parameters were estimated for various subgroups of patients classified according to the degree of liver damage. Then a multiple linear regression analysis was performed to select the best predictive models for vancomycin clearance (Clvan) and steady state distribution volume (V).. Results revealed that Clvan is not influenced by liver ...
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), ...

Each hospital was asked to complete questionnaires on 25 consecutive patients or all patients for whom vancomycin was prescribed during a 1-month period. RESULTS: In Survey I, 55 of 65 (85%) hospitals reported their vancomycin control policies. Three ...
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 ...
Monitoring of vancomycin trough concentrations is recommended for pediatric patients in the product label and by several professional societies. However, among a network of freestanding childrens hospitals vancomycin therapeutic drug monitoring (TDM) practices were reported to be highly variable. In this study, we sought to evaluate whether trends in vancomycin use and TDM changed across a large healthcare delivery system in Utah and Idaho from 2006 to 2012. Children ≤18 years who received ≥2 vancomycin doses were included. Overall, vancomycin TDM was performed during 5,035 (80%) of 6,259 hospital encounters, in which 85,442 doses were administered and 7,935 concentrations were obtained. Across this time period, the median trough concentration increased from 10.9 to 13.7 µg/mL (P | .001), which temporally coincided with recommendations published by the Infectious Disease Society of America that recommend targeting higher trough concentrations. Two or more abnormally low trough concentrations were

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 ...
The antibiotic vancomycin was effective in preventing bacterial contamination during studies with psittacosis and trachoma (PT) agents. This antibiotic was not toxic to chick embryos at 80 mg per egg, or to HeLa 229 cells cultivated in a medium containing 3,200 μg/ml of vancomycin; however, it was toxic to LLC-MK2 cells at a concentration of 1,600 μg/ml. Vancomycin did not affect the growth of a variety of PT agents at a concentration of 2 mg per egg or 800 μg per ml of cell culture medium, but it did inhibit the growth of common gram-positive bacterial air contaminants. ...

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.
Outer membrane of Gram-negative bacteria is a permeability barrier to many antibacterial agents, including the glycopeptide antibiotics such as vancomycin hydrochloride and as a result these antibiotics are ineffective against Gram negative bacteria. Different strategies have been described to overcome such limitation, including application of nanoparticles, as was shown in our previous studies for polymeric nanoparticles. On the other hand, some nanoparticles have the ability to reduce the permeation of drugs through biological barriers. Therefore, in this investigation, the effects of fusogenic liposomes, which are expected to interact well with biological barriers, toward antimicrobial effects of vancomycin in different bacteria, are investigated. Vancomycin-loaded liposomes were prepared by lipid film hydration method from a phospholipid mixture composed of either DPPC: DOPE: Chol or DPPC: DOPE: CHEMS, both in 1: 0.5: 1 molar ratios. Obtained liposomes were then assessed in regard to their
Current treatments for methicillin-resistant Staphylococcus aureus (MRSA) infections require intravenously delivered vancomycin; however, systemically delivered vancomycin has its problems. To determine the feasibility and safety of locally delivering vancomycin hydrochloride (~25 mg/Kg) to the medullary canal of long bones, we conducted a pharmacokinetics study using a rat tibia model. We found that administering the vancomycin intraosseously resulted in very low concentrations of vancomycin in the blood plasma and the muscle surrounding the tibia, reducing the risk for systemic toxicity, which is often seen with traditional intravenous administration of vancomycin. Additionally, we were able to inhibit the development of osteomyelitis in the tibia if the treatment was administered locally at the same time as a bacterial inoculum (i.e., Log10 7.82 CFU/mL or 6.62x107 CFU/mL), when compared to an untreated group. These findings suggest that local intramedullary vancomycin delivery can achieve ...

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
Enterococcus are intrinsically resistant to many of the antibiotics used in clinical practice. Moreover, they have acquired resistance to other antibiotics, with the consequent appearance of multiresistant strains, turning treatment of these infections very difficult in many cases. Vancomycin. Particularly worisome is the acquisition of vancomycin resistance in enterococcal strains. Vancomycin is considered a last resource antibiotic in the treatment of multiresistant enterococcal strains and is also used to treat infections caused by other pathogens like Staphylococcus, Streptococcus and Clostridium. After the introduction of this antibiotic into the clinical practice in the 80s, the first report of VRE (Vancomycin-Resistant Enterococcus) appreared soon in 1986. Vancomycin resistance is now spread both in the Hospital settings and in other environments. Vancomycin resistance in Enterococcus is generally acquired and is encoded in genetic mobile elements, like transposons. It can be associated ...
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

The purpose of this observational study is to evaluate the effect of an active pharmacy intervention to facilitate timely discontinuation of empiric vancomycin therapy in oncology patients with febrile neutropenia who lack objective evidence of a Gram-positive infection. This was a two-phase study. Vancomycin use was evaluated retrospectively on all oncology patients with febrile neutropenia over four weeks (phase I). In a parallel four weeks a year later, vancomycin use in this patient population was evaluated prospectively (phase II). In the absence of evidence of Gram-positive infection after 72 hours of treatment initiation, the team was contacted by a pharmacist to encourage discontinuation. Usage was compared between both phases. Forty-three patients in phase I and 25 patients in phase II were treated with vancomycin with no evidence for Gram-positive infections. Pharmacists interventions were documented on 18 patients in phase II. Of these, 56% of interventions to discontinue vancomycin ...

Vancomycin became available for clinical use ,50 years ago but was soon discarded in favor of other antibiotics that were deemed to be more efficacious and less toxic. The advent of pseudomembranous enterocolitis, coupled with the spread of methicillin-resistant Staphylococcus aureus, led to a resurgence in the use of vancomycin. Almost immediately, concerns arose with regard to its therapeutic utility. In addition, resistance to vancomycin developed, first in enterococci and later in staphylococci. Several types of resistance have now been identified, each with a unique effect on infections treated with vancomycin. Recent studies have rekindled interest in the best way to administer the antibiotic. The findings of future studies may result in a return to measuring levels of vancomycin in serum, to assure a successful therapeutic outcome.. ...
Introduction DRESS (drug reaction and eosinophilia with systemic symptoms) syndrome is a severe drug-induced reaction most typically characterized by fevers, lymphadenopathy, transaminitis, kidney injury, and/or rash. We present a case of DRESS syndrome after vancomycin administration masquerading as Red Man syndrome. Case Description A 63-year old woman with history of Rheumatoid arthritis, hyperlipidemia, and recent right foot osteomyelitis presented to our hospital with fever, malaise, and a diffuse macular, erythematous, blanching rash which started after receiving vancomycin. She had been receiving vancomycin for 4 weeks at the time of presentation for her osteomyelitis. Her symptoms were initially attributed to Red Man Syndrome secondary to rapid infusion of vancomycin, and she was treated with antihistamines with immediate resolution of her rash. The next day, she was noted to have recurrent fevers, worsening rash, transaminitis, and significant eosinophilia. The RegiSCAR (European Registry of
Vancomycin pharmacokinetics are significantly altered following burn injury, requiring a higher total daily dose to achieve adequate serum concentrations. Wide interpatient variability necessitates close, frequent monitoring of serum concentrations for efficacy and safety. The aim of this study is to systematically evaluate published data regarding vancomycin pharmacokinetic alterations in burn patients, to determine whether evidence-based recommendations for dosing and monitoring can be formulated, and to identify future research opportunities. The systematic review included studies published in English, involved human subjects with at least a 10% TBSA burn who received vancomycin intravenously, and obtained serum concentration(s). Database searches returned 130 titles for review. Twelve studies met a priori inclusion criteria. The most common dosing regimens in adult and pediatric patients were 5 to 20 mg/kg/dose every 6 to 8 hours. Mean trough concentrations were 7.24 ± 1.5 mg/L. Only 12.5% of

Both methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-sensitive S. aureus (MSSA) are rapidly overcoming the current array of drugs. One hundred and fifty isolates from a hospital were studied for resistance towards linezolid and vancomycin. Fifty-four (36.0 %) isolates were MRSA. Both MRSA and MSSA showed high resistance towards linezolid when using the disc diffusion method, with the figures being 48.1 and 29.2 %, respectively. The figures for the E-test were 46.3 and 27.0 %, respectively. The vancomycin resistance was remarkable in MRSA (14.8 %), but relatively low in MSSA (3.1 %). The E-test results were 13.0 and 4.16 %, respectively. The cfr gene was detected in 78 % of linezolid-resistant isolates and the vanA operon was detected in 74 % of vancomycin-resistant isolates. This level of resistance against linezolid and vancomycin is unprecedented. These results are alarming and highlight the threat of non-treatable S. aureus strains.
Vancomycin trough (Vt) concentrations of 15-20 mcg/mL have been associated with an increased rate of renal injury in adults. Current data in pediatrics suggests Vts of 15-20 mcg/mL do not increase the risk of renal injury in children admitted to a pediatric intensive care unit (PICU). The primary objective was to determine if a difference exists in the incidence of renal injury in PICU patients receiving a β-lactam as compared with vancomycin therapy with Vts of 15-20 mcg/mL. This was a retrospective cohort study conducted within a PICU within a freestanding tertiary care pediatric hospital. The records of children admitted to the PICU between 10/2008-6/2009 who received vancomycin for ≥48 h targeting higher Vt concentrations of ≥15 mcg/mL for pneumonia, bacteremia, and meningitis were reviewed. This cohort (V group) was compared to children admitted from July 2009-July 2013 who received cefepime or piperacillin/tazobactam for ≥72 h (B group). Serum creatinine values were collected from 48 h
We present a unique case of vancomycin-induced drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome masquerading as elusive endocarditis. A 37-year-old female actively using intravenous drugs presented with worsening right upper extremity pain, fever, and chills. Workup revealed methicillin-resistant staphylococcus aureus (MRSA) bacteremia and multiple right-sided septic pulmonary emboli. Echocardiogram was negative for vegetation. Vancomycin was initiated for bacteremia management suspected secondary to right upper extremity abscesses. However, despite resolution of abscesses, fevers persisted, raising suspicion for endocarditis not detected by echocardiogram. On hospital day 25, the patient began showing signs of DRESS syndrome, ultimately manifesting as transaminitis, eosinophilia, and a diffuse, maculopapular rash. Vancomycin was switched to Linezolid and she improved on high dose steroids. The persistent fevers throughout this hospital course were thought to be an elusive
Six complexes of vancomycin and peptidoglycan precursors were studied via molecular dynamics simulations. The interactions between the antibiotic and peptidoglycan fragments were identified and described in detail. All six studied modifications of the peptidoglycan precursor resulted in a weakening of the interaction with vancomycin when comparing to the native D-Ala-D-Ala-terminated fragment. It was confirmed that the N-terminus of the vancomycin is directly responsible for peptidoglycan recognition and antimicrobial activity. In simulated systems, the saccharide part of the antibiotic interacts with peptide precursors, thus it could also be important for antimicrobial activity. The complex terminated with D-Lac is the only one in which there is a weak interaction with the sugar moiety in the simulated systems. Analysis of conformational changes is a major scope of this work. The lack of interactions resulting from modification of the peptidoglycan precursors (D-Lac, D-Ser or other ...
Aims: To investigate the antibacterial efficacy of vancomycin towards Staphylococcus aureus under aerobic and anaerobic conditions, and to assess the influence of oxygen on the duration of the post-antibiotic effect (PAE) after exposure to vancomycin. Methods and Results: Culture-based techniques and flow cytometric measurements of 5-cyano-2,3-ditolyl tetrazolium chloride (an indicator of redox activity) and the membrane potential-sensitive fluorophore Sytox Green, were used to test four staphylococcal strains. The MICs for all strains, and the duration of PAE, were similar whether tested with or without oxygen. However, a fivefold logarithmic reduction in cell counts was observed in 10-15 h aerobically, depending on strain, compared with longer than 60 h in an anaerobic environment. Flow cytometric data correlated well with counts of colony-forming units under both aerobic and anaerobic conditions. Conclusions: The death rate of Staph. aureus exposed to vancomycin was greater in the presence of ...

Importance β-Lactam antibiotics are often coadministered with intravenous (IV) vancomycin hydrochloride for children with suspected serious infections. For adults, the combination of IV vancomycin plus piperacillin sodium/tazobactam sodium is associated with a higher risk of acute kidney injury (AKI) compared with vancomycin plus 1 other β-lactam antibiotic. However, few studies have evaluated the safety of this combination for children.. Objective To assess the risk of AKI in children during concomitant therapy with vancomycin and 1 antipseudomonal β-lactam antibiotic throughout the first week of hospitalization.. Design, Setting, and Participants This retrospective cohort study focused on children hospitalized for 3 or more days who received IV vancomycin plus 1 other antipseudomonal β-lactam combination ...
Introduction: Percutaneously inserted double-lumen central venous hemodialysis catheters provide the nephrologist with an excellent temporary access for an immediate hemodialysis treatment and preserve the peripheral veins for the future creation of a permanent arteriovenous vascular access. Unfortunately catheterrelated infections are usually common. In this study, the impact of intra luminal vancomycin administration on catheter-related infections in a group of hemodialyzed patients has been investigated. Method: A total of 100 patients with renal failure requiring hemodialysis by way of double-lumen central venous catheters inserted into the internal jugular or subclavian vein in 6 months period, were randomly divided into two groups of receiving a single intravenous dose of 1000 mg of vancomycin during catheter insertion and no antibiotics. The rate of infection, in situ duration of the initial catheter, number of dialysis sessions per week, site of catheter, length of the catheter which was outside
October 09, 2012. Antibiotic treatment of mild-to-moderate C. Difficile Colitis is generally with oral metronidazole or oral vancomycin. The recommended regimen is 500 mg 3 times daily or 250 mg 4 times daily for 14 days. If oral vancomycin is used, the dosage is 125 mg 4 times daily for 14 days. Intravenous metronidazole may be used if oral therapy cannot be given, but intravenous vancomycin has no clinical effect on C difficile colitis. Emerg Med Clin N Am 29 (2011) 347-368. ...
TY - JOUR. T1 - The epidemiology of vancomycin resistant enterococcus (VRE); The first 1044 isolates. AU - Perl, T. M.. AU - Karanfil, L. K.. AU - Pryor, P.. PY - 1997/12/1. Y1 - 1997/12/1. N2 - VRE are concerning nosocomial pathogens because of the limited therapeutic options and the potential to transfer the resistance genes to methicillin-resistant Staphylococcus aureus. Between 1989 and 1996, we maintained a database which includes demographic and clinical data on all JHH patients with VRE colonization or infection (C/I). VRE culture rates increased from 0.90/1000 patient discharges (pdc) in 1989 to 7.3/1000 pdc in 1996. The most significant increases have occurred on the solid organ transplant and the pediatric services. Among the first 1044 patients who developed VRE C/I; 22% were in intensive care units, 9% on oncology wards, 3% on pediatric wards, and 4% on solid organ transplant service. Over 50% of patients were housed on medical and surgical wards. Cases were distributed throughout ...
Staphylococcus aureus is one of the major pathogens causing serious infections both within the hospital setting and in the community. This pathogen is characterized by rapid acquisition of resistance to antibiotics introduced into clinical practice. Thus, methicillin-resistant S. aureus (MRSA) emerged first in the hospital setting and then spread to the community (CA-MRSA) [1]. In the late 1990s, MRSA strains emerged with reduced susceptibility to vancomycin, VISA (vancomycin-intermediate S. aureus) [2] and VRSA (vancomycin-resistant S. aureus) [3]. Tigecycline (TIG) is an antibiotic belonging to the glycylcyclines class and representing a treatment option for infections caused by S. aureus [4]. Surveillance studies of S. aureus have exhibited good activity of this antibiotic, with 99.9 % of isolates found to be susceptible [5]. A high susceptibility rate was also reported in Latin America from 2004 to 2010 [6] and in several countries around the world [7, 8]. The aim of this work was to select ...
Little is known about risk factors for subsequent infections among vancomycin resistant Enterococcus faecium (VREfm) colonizers, especially characterized by concordant pulsotypes (CP) of paired colonization and infection-related isolates. This case-control study was conducted at a teaching hospital between 2011 and 2014. Targeted patients received active surveillance culture for VREfm by anal swabs at admission. Cases were those who developed VREfm infection within 180 days after colonization of VREfm. Controls were those colonized with VREfm without subsequent VREfm infection. CP were defined by similarities ≥86.7% using pulsed-field gel electrophoresis between paired colonization and infection-related isolates. Ninety-seven cases and 194 controls were enrolled. By conditional multivariable logistic regression analysis, the risk factors for subsequent infection among VREfm colonizers were intensive care unit (ICU) admission (adjusted odds ratio [aOR], 9.32; 95% CI, 3.61-24.02), receipt of central
BioAssay record AID 67253 submitted by ChEMBL: In vitro antibacterial activity against vancomycin resistant Enterococcus faecalis (VanA, BM4166).
The frequency of infections with multiply antibiotic-resistant gram-positive bacteria is increasing, and in some cases these organisms remain susceptible only to the glycopeptides vancomycin and teicoplanin. The appearance of transferable high-level glycopeptide resistance in enterococci- producing some strains that are now resistant to all available antibiotics-is thus a cause for concern. The enterococci readily colonize the bowel, spread rapidly among hospital patients, and transfer their antibiotic resistances widely among themselves and other gram-positive species. Glycopeptide resistance has not yet transferred in vivo to other significant pathogens, but experimental transfer to Staphylococcus aureus has been achieved in vitro. The emergence of glycopeptideresistant enterococci has been encouraged by the increasing use of aminoglycosides, cephalosporins, and quinolones for the treatment of infections due to gram-negative bacteria and glycopeptides for infections due to staphylococci and ...
In this meta-analysis, a comprehensive search of multiple electronic databases and bibliographies was conducted to identify clinical studies that evaluated the rates of surgical site infection with and without the use of intrawound vancomycin powder in spine surgery. Independent reviewers extracted data and graded the quality of each paper that met inclusion criteria. A random effects meta-analysis was then performed.. The research identified eight retrospective cohort studies (level III evidence) and one randomised controlled trial (level II). There were 2,424 cases and 95 infections in the control group (3.9%) and 2,368 cases and 28 infections (1.1%) in the treatment group, yielding a pooled absolute risk reduction and relative risk reduction of 2.8% and 72%, respectively. The meta-analysis revealed the use of vancomycin powder to be protective in preventing infection (relative risk=0.30, 95% confidence interval 0.14-0.67, p,0.011). The number needed to treat to prevent one infection was 36. A ...

Update on the emerging role of telavancin in hospital-acquired infections Obinna N Nnedu,1 George A Pankey2 1Infectious Disease Department, Ochsner Clinic Foundation, New Orleans, LA, USA; 2Infectious Disease Research, Ochsner Clinic Foundation, New Orleans, LA, USA Abstract: Telavancin is a lipoglycopeptide that has activity against gram-positive aerobic and anaerobic bacteria. It has activity against methicillin-resistant Staphylococcus aureus, vancomycin-intermediate S. aureus and non-Van-A strains of vancomycin-resistant enterococci. It has been approved by the US Food and Drug Administration (FDA) for complicated skin and skin structure infections and hospital-acquired pneumonia. There is a need for more clinical studies to determine the role of telavancin in treating bacteremia and prosthetic device infections. In this review, we discuss the published data on the use of telavancin in treating hospital-acquired infections and provide an update on new research. Keywords: telavancin, vancomycin,
Using oral antibiotics when possible and limiting the durations of vancomycin treatment may decrease V-AKI in patients with ABSSSI.
The emerging problem of intermediate resistance to the glycopeptide antibiotic vancomycin in Staphylococcus aureus isolates has raised concern, since few therapeutic options remain for treatment. The antibiotics kill gram-positive bacteria by interfering with the synthesis of peptidoglycan on the bacterial surface. To identify any cell-surface alterations that correlated with increased resistance, MRSEC researchers Hahm and Sibener, working in conjunction with infectious disease experts Prof. Robert Daum and Dr. Susan Boyle-Vavra of the UC Pritzker Medical School, imaged the bacterial particles with AFM (A).. High-resolution images showed that resistant strains of the bacteria had shallow grooves on their surfaces (B) but that susceptible strains had deeper grooves and often a larger number of surface features (C). While the mechanistic significance of these phenotypic differences are not clear, the use of AFM imaging has provided a new opportunity for identifying and then understanding modes of ...

A panel of Enterococcus strains which have been tested for resistance to vancomycin and teicoplanin. The presence of |i>vanA, vanB,|/i> or |i>vanC|/i> genes in resistant strains has been confirmed by molecular testing at ATCC.
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 ...

Employing novel dosing regimens and antimicrobials are advantageous to combat the therapeutic problems associated with S. aureus IE. The administration of short courses of combination regimens involving aminoglycosides has previously demonstrated benefit and efficacy in treating IE. Korzeniowski and Sande found that the administration of nafcillin for 6 weeks and gentamicin for 2 weeks resulted in a more rapid mean clinical response and a reduced duration of bacteremia in patients with right-sided endocarditis (25). In addition, other investigators have shown that the outcomes of patients receiving 2-week combination aminoglycoside therapy were similar to the outcomes of patients receiving 4- to 6-week regimens (12, 17, 42). There have been no human studies investigating the effect of administering aminoglycosides in combination for less than 24 h against S. aureus IE. We attempted to investigate whether short-course, 24-h regimens of gentamicin in combination with vancomycin or daptomycin can ...

The presence of diabetes mellitus increases the risk of several severe infections, but data on its effect on treatment outcomes in patients with nosocomial pneumonia (NP) caused by methicillin-resistant Staphylococcus aureus (MRSA) are limited. We retrospectively analyzed data from a double-blind, randomized, multi-center, international clinical trial of culture-confirmed MRSA NP that compared treatment with linezolid to vancomycin. Specifically, we evaluated the clinical and microbiologic outcomes of patients with and without diabetes in the modified intent to treat population at end-of-treatment (EOT) and end-of-study (EOS, 7-30 days post-EOT). Among 448 enrolled patients 183 (40.8 %) had diabetes mellitus, 87 (47.5 %) of whom received linezolid and 96 (52.5 %) vancomycin. Baseline demographic and clinical characteristics were similar for the two treatment groups. Clinical success rates at EOS were 57.6 % with linezolid and 39.3 % with vancomycin, while microbiological success rates were 58.9 % with
A 14-year-old male with bilateral above-the-knee amputations presented to our hospital for treatment of a skin and soft-tissue infection. We report the experience of vancomycin and gentamicin therapy in this patient. Because these medications require weight-based dosages and pharmacokinetic monitoring of serum levels, it was necessary to obtain peak and trough levels of the two drugs in order to determine the pharmacokinetic differences in this patient compared to those in an adolescent male without amputations. To our knowledge, this is the first report describing pharmacokinetic differences in an adolescent amputee.

Avoparcin, a glycopeptide antimicrobial agent related to vancomycin, has been used extensively as a growth promoter in animal feeds for more than 2 decades, and evidence has shown that such use contributed to the development of vancomycin-resistant enterococci. A cluster that includes three genes, vanH, vanA, and vanX, is required for high-level resistance to glycopeptides. In the vancomycin producer Amycolatopsis orientalis C329.2, homologs of these genes are present, suggesting an origin for the cluster. We found substantial bacterial DNA contamination in animal-feed-grade avoparcin. Furthermore, nucleotide sequences related to the cluster vanHAX are present in this DNA, suggesting that the prolonged use of avoparcin in agriculture led to the uptake of glycopeptide resistance genes by animal commensal bacteria, which were subsequently transferred to humans.
A 59-year-old man with a history of intravenous drug use (DU) presented with a 3-day history of right-hand swelling, redness, warmth and pain. Physical examination was notable for a tensely oedematous hand with non-pitting oedema, warmth, blanching erythema and decreased range of motion (figure 1). He was empirically started on intravenous vancomycin for presumed skin and soft-tissue infection (SSTI). The patient was afebrile and studies including C reactive protein, leucocyte count and blood cultures were normal. An ultrasound study did not reveal any deep vein thrombosis. X-rays showed no fracture, foreign bodies or gas formation. There was no improvement after 48 hours of antibiotic therapy. MRI of the hand showed diffuse myositis of the intrinsic hand muscles and surrounding skin oedema (figures 2 and 3). Initially, he denied intravenous drug use into his arms, however, on further questioning, the patient admitted to injecting methamphetamine. Although he denied recent use, urine toxicology ...
The action of vancomycin and teicoplanin depends on their ability to bind specifically to the terminal D-alanyl-D-alanine group on the peptide side chain of the membrane-bound intermediates in peptidoglycan synthesis. Bacitracin was isolated in 1943 from a strain of a Bacillus sp., which was originally classified as Bacillus subtilis but now is known as Bacillus licheniformis. Binding of bacitracin prevents the enzymatic dephosphorylation of the lipid carrier molecule to its monophosphate form, a reaction which occurs during the second stage of peptidoglycan biosynthesis. Bacitracin is highly active against most gram-positive bacteria, particularly Staphylococcus aureus and Streptococcus pyogenes. Vancomycin binds reversibly to the D-Ala-D-Ala dipeptide segment of the muramyl pentapeptide present in peptidoglycan monomers which are exposed at the external cell surface of the cytoplasmic membrane. The dimeric structure of vancomycin is held together by four hydrogen bonds between the two amide backbones.
The increased prevalence of vancomycin-intermediate (VISA) can be an emerging healthcare threat. site-specific allelic variant within and between isolate populations. Inhabitants hereditary methods were after that applied to measure the general levels of variant over the three period points also to determine individual variations that display anomalous degrees of allelic modification between populations. A successive Nutlin 3b decrease in the overall degrees of inhabitants genomic variant was observed over the three period points in keeping with a inhabitants bottleneck caused by antibiotic treatment. Not surprisingly general reduction in variant several individual mutations had been swept to high rate of recurrence in the VISA inhabitants. These mutations had been implicated as possibly mixed up in VISA phenotype and interrogated regarding their functional jobs. This process allowed us to recognize several mutations previously Nutlin 3b implicated in VISA along with allelic adjustments within a ...

DescriptionMethicillin Resistant Staphylococcus aureus (MRSA) causes a myriad of infections ranging from mild skin-infection to more serious infections affecting internal organs. A glycopeptide, Vancomycin, remains the last line of defense against MRSA. The aim of this study is to investigate whether liposomal encapsulated Vancomycin had a better antimicrobial action than free Vancomycin in terms of infection-specific targeting and circulation time. For the same, encapsulation efficiency and release kinetics of the liposomes was evaluated along with Minimum Inhibitory Concentrations (MIC) of the liposomal preparations. The liposomes showcased a 12-15% encapsulation efficiency. Sustained release at pH 6.0 as compared to little to no release at pH 7.4 was demonstrated by the pH sensitive liposomes. Also, in acidic pH, an increase in efficacy was observed with a greater decrease in the MIC of the pH responsive liposomes as compared to the lower decrease in MIC of the non pH-responsive liposomes and ...
In a recent small trial, 43 patients (mean age 68 years) with recurrent C. difficile diarrhea after at least 1 course of antibiotics were randomized to 1 of 3 treatments. The first group had a 4-5 day course of vancomycin followed by bowel lavage and then donor feces infusion through nasoduodenal tube. Feces were diluted in 500 ml of 0.9% saline, stirred, and the supernatant was then administered within 6 hours following collection from donor. All donors were , 60 years old and screened for risk factors associated with potentially transmissible diseases. An additional infusion with feces from a different donor was given if infection recurred. The second group received a 14-day course of vancomycin plus lavage, and the third received vancomycin for 14 days only ...
