Linezolid was introduced in clinical practice in the early 2000s. It was considered to be an ideal reserve drug for treatment of vancomycin-resistant Enterococcus spp. (VRE) and vancomycin-resistant Staphylococcus aureus (VRSA). The aim of our study was to describe and evaluate the use of linezolid in clinical practice at the intensive care unit (ICU) of the Tunisian military hospital. This is ...

UNLABELLED Linezolid is an oxazolidinone with potent activity against Mycobacterium tuberculosis. Linezolid toxicity in patients correlates with the dose and duration of therapy. These toxicities are attributable to the inhibition of mitochondrial protein synthesis. Clinically relevant linezolid regimens were simulated in the in vitro hollow-fiber infection model (HFIM) system to identify the l...

Linezolid is an effective antimicrobial agent to treat methicillin-resistant Staphylococcus aureus (MRSA). Resistance to linezolid due to the cfr gene is described worldwide. The present study aimed to analyze the prevalence of the cfr-mediated linezolid resistance among MRSA clinical isolates in our area. A very low prevalence of cfr mediated linezolid resistance was found: only one bacteremic...

Linezolid may be effective in treating multidrug-resistant tuberculosis and extensively drug-resistant tuberculosis. We conducted a prospective, multicentre, randomised study to further evaluate the efficacy, safety and tolerability of linezolid in patients with extensively drug-resistant tuberculosis in China. 65 patients who had culture-positive sputum for extensively drug-resistant tuberculo...

OBJECTIVE To determine linezolid concentrations in peritoneal dialysis fluid after multiple oral doses of the drug in a 46-year-old man with vancomycin-resistant Enterococcus faecium peritonitis who was undergoing peritoneal dialysis. METHODS After administration of oral linezolid 600 mg twice/day was started, peritoneal dialysis fluid was collected at the end of several 4- and 8-hour dwell t...

OBJECTIVES Linezolid is an oxazolidinone antibiotic used in the treatment of infections caused by vancomycin-resistant enterococci. Resistance to linezolid has been associated with a G2576U mutation in domain V of the 23S rRNA. PATIENT AND METHODS We present clinical details and susceptibility data from multiple Enterococcus faecium strains isolated from a liver transplant patient over 13 mon...

OBJECTIVES Therapeutic options in Clostridium difficile infection (CDI) are limited. We examined linezolid activity in vitro and potential therapeutic efficacy using a gut model of CDI. METHODS MICs were determined by agar incorporation for 118 diverse C. difficile faecal isolates, including epidemic strains and strains with reduced susceptibility to metronidazole. CDI was established in two ...

BACKGROUND Although previous studies have suggested that linezolid may be effective for treating multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis (TB), the optimal dose of linezolid for intractable MDR/XDR-TB is not clear. METHODS Twenty-four patients with intractable MDR/XDR-TB were treated with a daily 300 mg dose of linezolid as part of their anti-TB drug regimen...

OBJECTIVE To determine the linezolid clearance and serum concentrations in a critically ill man receiving continuous venovenous hemodiafiltration (CVVHDF). METHODS Intravenous linezolid 600 mg every 12 hours was administered to a critically ill, 85-year-old man with anuria who was receiving CVVHDF at a dialysate flow rate of 2000 ml/hour and a mean ultrafiltrate production rate of 775 ml/hour...
