Effectiveness and duration of daptomycin therapy in resolving clinical symptoms in the treatment of complicated skin and skin structure infections.

Objective: Compare the rapidity of the resolution of clinical signs and symptoms of complicated skin and skin structure infections (cSSSIs) caused by gram-positive organisms between daptomycin and comparator agents.

Patients And Methods: A subset of South African patients with gram-positive cSSSIs and no or one comorbid condition from two phase III clinical trials were included in the analysis. Patients were treated with daptomycin (n = 174) or comparator (penicillinase-resistant penicillins [n = 146] or vancomycin [n = 6]).

Daptomycin versus standard therapy for bacteremia and endocarditis caused by Staphylococcus aureus.

Background: Alternative therapies for Staphylococcus aureus bacteremia and endocarditis are needed.

Methods: We randomly assigned 124 patients with S. aureus bacteremia with or without endocarditis to receive 6 mg of daptomycin intravenously per kilogram of body weight daily and 122 to receive initial low-dose gentamicin plus either an antistaphylococcal penicillin or vancomycin.

Daptomycin: a novel agent for Gram-positive infections.

The alarming increase in the incidence of Gram-positive infections, including those caused by resistant bacteria, has sparked renewed interest in novel antibiotics. One such agent is daptomycin, a novel lipopeptide antibiotic with proven bactericidal activity in vitro against all clinically relevant Gram-positive bacteria. These include resistant pathogens, such as vancomycin-resistant enterococci (VRE), methicillin-resistant Staphylococcus aureus (MRSA), glycopeptide intermediately susceptible Staphylococcus aureus (GISA), coagulase-negative staphylococci (CNS) and penicillin-resistant Streptococcus pneumoniae (PRSP), for which there are very few therapeutic alternatives.

Daptomycin: a lipopeptide antibiotic for the treatment of serious Gram-positive infections.

Infections caused by drug-resistant pathogens are on the rise. Daptomycin, a cyclic lipopeptide with activity against most Gram-positive pathogens, including vancomycin-resistant enterococci and methicillin-resistant Staphylococcus aureus, is a newly US-FDA approved antimicrobial for complicated skin and skin structure infections (cSSSI). Daptomycin has a unique mechanism of action that results in destruction of the membrane potential.
