BACKGROUND Glycopeptides such as vancomycin are frequently the antibiotics of choice for the treatment of infections caused by methicillin resistant Staphylococcus aureus (MRSA). For the last 7 years incidence of vancomycin intermediate S. aureus and vancomycin resistant S. aureus (VISA and VRSA respectively) has been increasing in various parts of the world. The present study was carried out t...
Nitazoxanide versus vancomycin in Clostridium difficile infection: a randomized, double-blind study.
BACKGROUND Vancomycin is the only US Food and Drug Administration-approved drug for treatment of Clostridium difficile infection (CDI). Metronidazole has been widely used for this purpose but may be inferior to vancomycin, especially for hospitalized patients with severe disease. We report a prospective, double-blind, randomized controlled trial comparing nitazoxanide with vancomycin for treatm...
Despite the need for effective vancomycin therapy, there are few data guiding vancomycin monitoring in children. We reviewed retrospectively vancomycin use in children 1 month to 12 years of age. Initial and adjusted target trough vancomycin concentrations in serum were infrequently achieved regardless of the dosing schedule. Currently recommended trough concentrations need to be re-examined wi...
OBJECTIVES To measure the concentrations of vancomycin in the vitreous of patients with postoperative endophthalmitis after administration of 1 g of vancomycin hydrochloride intravenously and injection of 1 mg of vancomycin hydrochloride into the vitreous, and to determine whether these concentrations are adequate for treatment of gram-positive infections. METHODS Patients with acute postoper...
BACKGROUND Evidence from a recent randomized controlled trial suggests that dexamethasone as adjunct therapy in adult pneumococcal meningitis reduces mortality and neurological sequelae. However, adding dexamethasone has the potential to reduce penetration of vancomycin into the cerebrospinal fluid (CSF). We sought to determine concentrations of vancomycin in serum and CSF of patients with susp...
A ratio of the vancomycin area under the concentration-time curve to the MIC (AUC/MIC) of ≥ 400 has been associated with clinical success when treating Staphylococcus aureus pneumonia, and this target was recommended by recently published vancomycin therapeutic monitoring consensus guidelines for treating all serious S. aureus infections. Here, vancomycin serum trough levels and vancomycin AUC/...
Glycopeptides are still the gold standard to treat MRSA (Methicillin Resistant Staphylococcus aureus) infections, but their widespread use has led to vancomycin-reduced susceptibility [heterogeneous Vancomycin-Intermediate-Staphylococcus aureus (hVISA) and Vancomycin-Intermediate-Staphylococcus aureus (VISA)], in which different genetic loci (regulatory, autolytic, cell-wall turnover and cell-e...
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 foun...
Vancomycin is an increasingly important option for the treatment of Clostridium difficile infection, but economic barriers to its use remain significant in the outpatient setting. Generic vancomycin capsules are still inexplicably expensive and not universally covered by insurers. This report highlights the potential adverse consequences of cost-related nonadherence to vancomycin therapy and th...
Vancomycin was radioactively labelled by iodination with (125)I.Iodinated vancomycin was only a little less potent as an antibiotic than vancomycin itself. It was shown, both by chromatography and differential absorption measurements, to combine with acyl-d-alanyl-d-alanine residues. Radioactive vancomycin was used to follow the fate of the antibiotic in bacteria that had been subjected to the ...
