The ability of fluconazole to penetrate into ventilated, healthy and inflamed lung tissue in a model of severe sepsis in rats.

Background/aims: We measured the extracellular concentrations of fluconazole in lung tissue of septic and healthy rats.

Methods: A single intravenous dose of 6 mg/kg total body weight of fluconazole was administered intravenously to rats following insertion of microdialysis probes into lung tissue. Another probe was inserted into skeletal muscle and served as control.

Rapid and sensitive determination of the antibiotic linezolid in low plasma volumes by high-performance liquid chromatography.

A rapid and sensitive method for the determination of linezolid by high-performance liquid chromatography (HPLC) with UV detection (251 nm) is presented. Linezolid is an important antibiotic against severe infections caused by multi-resistant bacterial pathogens. Scientific efforts continue investigating its effectiveness in different conditions and patient populations including children and newborns.

Linezolid concentrations in infected soft tissue and bone following repetitive doses in diabetic patients with bacterial foot infections.

The present study aimed at assessing unbound extracellular concentrations of linezolid in inflamed soft tissue and bone of diabetic patients suffering from severe bacterial foot infections. Linezolid was administered intravenously twice daily at a dosage of 600 mg. At steady-state conditions, the microdialysis technique was utilised to sample serially interstitial space fluid from inflamed subcutaneous adipose tissue and metatarsal bone from 0-8h post dose in three representative patients.

Soft tissue and bone penetration abilities of daptomycin in diabetic patients with bacterial foot infections.

Objectives: In the attempt to overcome increasing glycopeptide- and methicillin-resistant soft tissue infections, daptomycin is presently considered as an attractive alternative to the class of glycopeptides. However, daptomycin dosing and its ability to penetrate into inflamed target tissues are still a matter of controversy. Thus, in the present investigation, we set out to evaluate daptomycin's ability to penetrate into inflamed subcutaneous adipose tissue and bone in diabetic patients presenting with severe bacterial foot infection.

High fosfomycin concentrations in bone and peripheral soft tissue in diabetic patients presenting with bacterial foot infection.

Objectives: Appropriate antimicrobial therapy and surgical intervention may be required in diabetic patients presenting with severe bacterial foot infection. Methicillin-resistant Staphylococcus aureus (MRSA) agents such as fosfomycin are increasingly in demand because of recent concern regarding vancomycin and daptomycin efficacy and constant use. Intravenous fosfomycin is approved for the therapy of severe soft tissue infections and is highly active against methicillin-susceptible S.
