Initial low-dose gentamicin for Staphylococcus aureus bacteremia and endocarditis is nephrotoxic.

Background: The safety of adding initial low-dose gentamicin to antistaphylococcal penicillins or vancomycin for treatment of suspected Staphylococcus aureus native valve endocarditis is unknown. This study evaluated the association between this practice and nephrotoxicity.

Methods: We performed a prospective cohort study of safety data from a randomized, controlled trial of therapy for S.

Daptomycin versus vancomycin plus gentamicin for treatment of bacteraemia and endocarditis due to Staphylococcus aureus: subset analysis of patients infected with methicillin-resistant isolates.

Objectives: In a prospective, randomized trial, daptomycin was non-inferior to standard therapy for Staphylococcus aureus bacteraemia and right-sided endocarditis. Since rates of infection due to methicillin-resistant S. aureus (MRSA) infection are increasing and treatment outcomes for bacteraemia caused by MRSA are generally worse than those observed with methicillin-susceptible S.

The relationship between the initiation of antimicrobial therapy and the incidence of stroke in infective endocarditis: an analysis from the ICE Prospective Cohort Study (ICE-PCS).

Background: Embolic events to the central nervous system are a major cause of morbidity and mortality in patients with infective endocarditis (IE). The appropriate role of valvular surgery in reducing such embolic events is unclear. The purpose of this study was to determine the relationship between the initiation of antimicrobial therapy and the temporal incidence of stroke in patients with IE and to determine if this time course differs from that shown for embolic events in previous studies.

Outcomes with daptomycin versus standard therapy for osteoarticular infections associated with Staphylococcus aureus bacteraemia.

Objectives: To evaluate the clinical characteristics, treatment and outcomes of patients with osteoarticular infections (OAIs) associated with Staphylococcus aureus bacteraemia (SAB).

Methods: The clinical characteristics and outcomes for patients with OAI were described using a post hoc analysis of an open label, randomized trial comparing daptomycin with standard therapy (vancomycin or anti-staphylococcal penicillin with initial gentamicin) for the treatment of SAB.

Results: OAI occurred in 32 of 121 patients (21 daptomycin and 11 standard therapy) with complicated SAB (18 septic arthritis, 9 vertebral osteomyelitis and 7 others).

Propionibacterium endocarditis: a case series from the International Collaboration on Endocarditis Merged Database and Prospective Cohort Study.

Propionibacterium species are occasionally associated with serious systemic infections such as infective endocarditis. In this study, we examined the clinical features, complications and outcome of 15 patients with Propionibacterium endocarditis using the International Collaboration on Endocarditis Merged Database (ICE-MD) and Prospective Cohort Study (ICE-PCS), and compared the results to 28 cases previously reported in the literature. In the ICE database, 11 of 15 patients were male with a mean age of 52 y.
