title: Efficacy of teicoplanin for enterococcal infections: 63 cases and review.
abstract: Sixty-three cases of monomicrobial enterococcal infections treated with teicoplanin in two open clinical studies in Europe from 1982 to 1989 are presented. Infections were documented as endocarditis (n = 18); septicemia (n = 8); and urinary tract (n = 29), skin/soft-tissue (n = 6), or bone/joint (n = 2) infections. A total of 63 enterococcal strains were isolated; all of 29 strains tested were susceptible to teicoplanin (geometric mean MIC, 0.16 micrograms/mL; range, 0.06-0.5 micrograms/mL). Forty-eight patients were treated with teicoplanin alone and 15 were treated with teicoplanin in combination with an aminoglycoside. The rate of clinical cure was 84.1%; 4.8% of patients clinically improved, 7.9% had clinical recurrence, and 3.2% did not respond to therapy. Bacteriologic eradication was observed in 87.2% of patients; persistence, in 3.2%; recurrence, in 3.2%; and reinfection, in 4.8%. One case was not evaluable bacteriologically. Of 18 patients with endocarditis, 15 were cured with a mean daily dose of 5.4 mg/kg--six with monotherapy and nine with combination therapy. All patients with urinary tract infections were treated with monotherapy, and 89.7% were cured (mean daily dose, 4.6 mg/kg). Lower rates of clinical cure and bacteriologic eradication were observed in septicemic patients without endocarditis (62.5%). This study demonstrated a good efficacy of teicoplanin for the treatment of enterococcal infections due to susceptible strains, but further clinical studies would be useful for establishing optimal dosage and the indications for combination therapy, especially for severe infections.
