ReviewStrategies for managing systemic fungal infection and the place of itraconazole.
Systemic fungal infections are an increasing cause of mortality and morbidity in patients with haematological malignancies and certain other conditions associated with profound immunosuppression. The majority of such infections are caused by Aspergillus and Candida species. In recent years, the number of available drugs effective in the therapy of these difficult infections has expanded. ⋯ In the empirical setting, large randomized studies support the use of caspofungin and liposomal amphotericin B. Voriconazole and lipid-associated amphotericin B have been shown to be effective in first-line therapy and caspofungin for salvage. New approaches to management include efforts at improving diagnosis, combination antifungal therapy and treatment strategies for emerging moulds.

Randomized Controlled Trial Clinical TrialIsolation of fluoroquinolone-resistant rectal Escherichia coli after treatment of acute uncomplicated cystitis.
Given increasing rates of co-trimoxazole resistance among uropathogens causing acute uncomplicated cystitis, fluoroquinolones, nitrofurantoin and fosfomycin are often considered as alternative empirical therapy. The choice between these drugs should depend in part on whether they are associated with the isolation of drug-resistant microbial flora. We conducted a randomized treatment trial to assess the effects of ciprofloxacin, nitrofurantoin and fosfomycin on the rectal microbial flora of women with acute uncomplicated cystitis, including isolation of fluoroquinolone-resistant strains. ⋯ This study demonstrates that fluoroquinolone-resistant E. coli remain infrequent in the rectal flora of women with uncomplicated cystitis in Seattle. However, a 3 day course of a fluoroquinolone for treatment of uncomplicated cystitis was followed by isolation of fluoroquinolone-resistant rectal E. coli in one patient.

Multiple-dose pharmacokinetics of linezolid during continuous venovenous haemofiltration.
Linezolid is a new antibacterial agent with a broad spectrum of activity against Gram-positive pathogens including methicillin-resistant Staphylococcus aureus, vancomycin-resistant Enterococcus spp., and penicillin-resistant Streptococcus pneumoniae. The aim of this prospective, single-centre, open-label, two-arm study was to investigate the pharmacokinetics of linezolid during continuous venovenous haemofiltration (CVVH) in critically ill patients and to derive a dosage recommendation. ⋯ Our results showed that linezolid was highly removable by CVVH. These data suggest that a schedule of 600 mg linezolid at least twice daily may also be an appropriate dosing for patients with severe Gram-positive infections undergoing CVVH with both types of membranes.
