Treatment of infections by staphylococci and other gram-positive bacteria with teicoplanin: an open study.

Teicoplanin, 200-400 mg (3-6 mg/kg) daily iv or im, was used to treat 71 episodes of infection. The average duration of treatment was 22 days. The 64 evaluable episodes comprised 24 skin/soft tissue, 20 osteoarticular, ten urinary tract and one ventriculo-atrial shunt infections; one case of primary bacteraemia, three of endocarditis, two of pneumonia and three of pleural empyema. Fifty-five episodes were treated with teicoplanin monotherapy and nine with teicoplanin in association to other antibiotics. Overall 61% (39/64) of the evaluable infections were cured, 25% (16/64) improved and 14% (9/64) failed. Staphylococcus aureus was the most frequent pathogen, with 46 isolates. Infections by both methicillin-sensitive and resistant Staph. aureus strains showed favourable clinical and microbiological responses to teicoplanin. Side effects were observed in eight of the 64 episodes (12.5%). Bronchospasm was observed in two other cases at the beginning of therapy and the antibiotic administration was discontinued. Teicoplanin is an effective and well tolerated antibiotic for infections by Gram-positive bacteria, and it is effective against methicillin-resistant staphylococci.
