In recent years, serious skin and soft tissue infections (SSTIs) caused by multidrug resistant pathogens have become more common. While the majority of SSTIs are caused by Staphylococcus aureus or beta-haemolytic streptococci that are methicillin/oxacillin susceptible, the emergence of methicillin-resistant and vancomycin-resistant community-acquired and(More)
To discern whether the characteristics and outcome of invasive aspergillosis in liver transplant recipients have evolved during the past decade, 26 patients who underwent transplantation during 1990-1995 (known as "the earlier cohort") were compared with 20 patients who underwent transplantation during 1998-2001 (known as "the later cohort"). Twenty-three(More)
A progressive increase in the incidence of vancomycin resistance in strains of Enterococcus faecium (VREF) has severely constrained treatment options for patients with infection caused by this emerging pathogen. Quinupristin/dalfopristin (Synercid), the first injectable streptogramin antibiotic, is active in vitro against VREF, with an MIC90 of 1.0 mg/L. We(More)
The spectrum of available therapeutic options has become drastically narrowed in recent years, particularly for nosocomial multidrug-resistant gram-negative pathogens. This therapeutic void has created a resurgence of interest in colistin. In 5 published series since 1999, clinical response rates for pneumonia due to Pseudomonas aeruginosa or Acinetobacter(More)
Enterococcus spp. is now the third most common pathogen among hospitalized patients, accounting for nearly 12% of nosocomial infections. Enterococcus faecalis is the most prevalent enterococcal species (85%-89%), whereas Enterococcus faecium accounts for 10%-15% of enterococcal isolates. Only 5% of E. faecalis isolates are resistant to glycopeptides. E.(More)
To determine the spectrum and impact of mycelial fungal infections, particularly those due to non-Aspergillus molds, 53 liver and heart transplant recipients with invasive mycelial infections were prospectively identified in a multicenter study. Invasive mycelial infections were due to Aspergillus species in 69.8% of patients, to non-Aspergillus(More)
Serious infection due to strains of Pseudomonas aeruginosa that exhibit resistance to all common antipseudomonal antimicrobials increasingly is a serious problem. Colistin was used as salvage therapy for 23 critically ill patients with multidrug-resistant P. aeruginosa infection. Twenty-two patients who had septic shock (n=14) and/or renal failure (n=21)(More)
BACKGROUND Enterococcus species are major nosocomial pathogens and are exhibiting vancomycin resistance with increasing frequency. Previous studies have not resolved whether vancomycin resistance is an independent risk factor for death in patients with invasive disease due to Enterococcus species or whether antibiotic therapy alters the outcome of(More)
Solid organ transplantation is one of the most remarkable and dramatic therapeutic advances in medicine during the past 60 years. This field has progressed initially from what can accurately be termed a "clinical experiment" to routine and reliable practice, which has proven to be clinically effective, life-saving and cost-effective. This remarkable(More)
