OBJECTIVE Peripheral neuropathy (PN) and optic neuropathy (ON) associated with linezolid use are described in the adult literature; however limited information is available in pediatrics. The purpose of this communication is to summarize pediatric cases of linezolid-associated neuropathy and to increase awareness of these neurologic side effects so that clinicians can most appropriately balance...

OBJECTIVES The aim of the study was to assess the biliary penetration of linezolid and the probabilities of attaining optimal pharmacodynamic exposure against vancomycin-resistant enterococci (VRE) in the bile of liver transplant (LTx) patients who received linezolid for the treatment of multidrug-resistant Gram-positive hospital infections. METHODS After at least 2 days of standard 600 mg tw...

Clinical enterococcal resistance to linezolid is defined by the presence of the G2576T mutation. We evaluated the incidence of genetically proven linezolid resistance among vancomycin-resistant Enterococcus faecium strains and linezolid consumption for a possible association. A relationship was found (r(2) = 0.73, P = 0.03) and predicts increasing resistance with current trends of linezolid use.

The levels of effectiveness of linezolid, vancomycin, and the combination of linezolid and vancomycin were compared in the rabbit model of endocarditis caused by a clinical methicillin-resistant Staphylococcus aureus (MRSA) isolate. Vancomycin alone was more effective than either linezolid alone or the combination of linezolid and vancomycin for the treatment of endocarditis due to MRSA.

OBJECTIVES The G2576T mutation in domain V of 23S rRNA has been most often associated with the rare cases of linezolid resistance in Staphylococcus aureus. In a linezolid-susceptible S. aureus (A8761B) possessing a single mutated (G2576T) copy, originally derived from a resistant clinical isolate, we assessed the persistence of the mutation on further passage on antibiotic-free medium and the s...

PURPOSE The aim was to evaluate the stability of linezolid in commonly used intravenous fluids and in aqueous solution to determine the kinetics of degradation and shelf-life values at alkaline pH values. METHODS Forced degradation studies were performed on linezolid in solution to develop a validated high-performance liquid chromatography analysis. Sodium chloride 0.9%, sodium lactate, and g...

BACKGROUND The aim of this study was to compare the antibacterial efficacy of vancomycin and linezolid in a rabbit model of methicillin-resistant Staphylococcus aureus (MRSA) meningitis. MATERIAL/METHODS Meningitis was induced by intracisternal inoculation of ATCC 43300 strain. After 16 h incubation time and development of meningitis, the vancomycin group received vancomycin 20 mg/kg every 12...

sion were polytraumatism, brain trauma, respiratory failure, acute renal failure, peritonitis, necrotic pancreatitis, spontaneous brain haemorrhage and subarachnoid haemorrhage. Twelve of 26 strains were from patients with ,2–12 weeks of exposure to linezolid. This study describes the molecular epidemiology and the mechanism of linezolid resistance in S. epidermidis strains from Greece. Two int...

UNLABELLED INTRODUCTION Linezolid-induced black hairy tongue has been rarely reported. The purpose of this paper is to report a case of linezolid-induced black hairy tongue and review the literature. CASE PRESENTATION A 56-year-old Caucasian man was admitted with community-acquired pneumonia that failed to respond to levofloxacin 750mg daily. He was started on linezolid and meropenem and w...

We investigated the activity of linezolid, alone and in combination with rifampin (rifampicin), against a methicillin-resistant Staphylococcus aureus (MRSA) strain in vitro and in a guinea pig model of foreign-body infection. The MIC, minimal bactericidal concentration (MBC) in logarithmic phase, and MBC in stationary growth phase were 2.5, >20, and >20 microg/ml, respectively, for linezolid; 0...
