Randomized comparison trial of teicoplanin i.v., teicoplanin i.m., and cefazolin therapy for skin and soft tissue infections caused by gram-positive bacteria

Abstract

Teicoplanin, a glycopeptide antibiotic chemically related to the vancomycin-ristocetin group of antibiotics, has potent activity against aerobic and anaerobic gram-positive bacteria. In this study, we examined the efficacy and safety of teicoplanin for parenteral treatment of skin and soft tissue infections caused by gram-positive bacteria. Ninety-six hospitalized adults with moderate to severe skin and soft tissue infections were randomized to receive either teicoplanin intravenously (i.v.) once a day, teicoplanin intramuscularly (i.m.) once a day, or cefazolin i.v. every 8 hours. We evaluated patients' clinical and microbiologic status and assessed clinical and laboratory adverse events. Of 76 clinically assessable patients, 26 of 26 (100%) given teicoplanin i.v., 21 of 22 (95%) given teicoplanin i.m., and 26 of 28 (93%) given cefazolin showed improvement or cure. Of 60 microbiologically assessable patients, 22 of 22 (100%) given teicoplanin i.v., 16 of 18 (89%) given teicoplanin i.m, and 18 of 20 (90%) given cefazolin were cured. Of 96 patients assessable for adverse events, 7 of 34 (21%) given teicoplanin i.v., 4 of 31 (13%) give teicoplanin i.m., and 1 of 31 (3%) given cefazolin had adverse events. In this study, once daily teicoplanin appeared to be safe and effective therapy for skin and soft tissue infections.
