Management of candidaemia and invasive candidiasis in critically ill patients.
Critically ill patients in the intensive care unit (ICU) are at increased risk of encountering bloodstream infections (BSIs) with Candida spp., associated with an elevated crude mortality rate. This supports the significance of early detection of infection and identification of the most effective management approach. A review of the various antifungal treatments and an evaluation of the diverse management approaches for invasive candidiasis in critically ill patients is necessary for guiding evidence-based decision-making. ⋯ This paper summarises the most recent literature as well as the guidelines issued by the Infectious Diseases Society of America. The objective is to identify the best diagnosis and management approaches for serious Candida infections in critically ill patients. In addition, this article addresses an important aspect associated with managing candidaemia in critically ill patients pertaining to the decision for intravenous catheter removal.

Case ReportsSuccessful treatment of extensively drug-resistant Acinetobacter baumannii ventriculitis and meningitis with intraventricular colistin after application of a loading dose: a case series.
Treatment results of six post-neurosurgical ventriculitis and meningitis cases caused by extensively drug-resistant Acinetobacter baumannii after application of an intraventricular loading dose of 500000 IU (40 mg) of colistin followed by a dose of 125000-250000 IU (10-20 mg) every 24-48 h plus parenteral colistin are reported. Simultaneous bacteraemia with an identical Acinetobacter strain was observed in three patients. The mean duration of treatment was 17.2 days (range 15-21 days) and the median time of sterilisation of cerebrospinal fluid was 2.5 days (range 1-5 days). All patients were cured, however one patient presented with chemical meningitis and one with chemical ventriculitis, conditions that clinically and biochemically resemble bacterial meningitis.

Implementation of a protocol for administration of vancomycin by continuous infusion: pharmacokinetic, pharmacodynamic and toxicological aspects.
Optimising antibiotic administration is critical when dealing with pathogens with reduced susceptibility. Vancomycin activity is dependent on the area under the concentration-time curve over 24 h at steady-state divided by the minimum inhibitory concentration (AUC/MIC), making continuous infusion (CI) or conventional twice daily administration pharmacodynamically equipotent. ⋯ Recursive partitioning analysis of AUC/MIC ratios versus success or failure suggested threshold values of 667 (total serum level) and 451 (free serum level), corresponding to organisms with a MIC>1 mg/L. Nephrotoxicity potentially related to vancomycin was observed in 10% of patients, but treatment had to be discontinued in only two of them.

Effectiveness and safety of daptomycin in complicated skin and soft-tissue infections and bacteraemia in clinical practice: results of a large non-interventional study.
This retrospective analysis of patients from eight countries included in the European Cubicin(®) Outcomes Registry and Experience (EU-CORE(SM)) captures the first post-approval years of clinical experience with daptomycin in its licensed indications. Of the total 1127 patients enrolled in EU-CORE between 2006 and 2008, 373 had a primary complicated skin and soft-tissue infection (cSSTI), most commonly surgical-site infection (48%), and 244 had bacteraemia, 55% of which were catheter-related. The most common pathogens were Staphylococcus aureus in cSSTIs (43%) and coagulase-negative staphylococci in bacteraemia (36%). ⋯ Daptomycin demonstrated a favourable safety profile. Adverse events regardless of relationship to study drug were reported for 11% of patients with cSSTIs and 24% with bacteraemia, most commonly septic shock [7 patients (2%) with cSSTIs and 5 patients (2%) with bacteraemia]. These results demonstrate that daptomycin is effective and well tolerated in the treatment of cSSTIs and bacteraemia caused by Gram-positive bacteria in clinical practice.
