Renal and auditory toxicity of high-dose, prolonged therapy with gentamicin and tobramycin in pseudomonas endocarditis.
The nephrotoxicity and auditory toxicity of high-dose (mean, 28.6 g) and prolonged (mean, 61.6 days) courses of gentamicin and tobramycin were monitored in 15 patients receiving 17 courses of treatment for pseudomonas endocarditis. Doses were adjusted in a manner that maintained peak levels of aminoglycoside in serum at 12-15 micrograms/ml and trough levels at less than 2 micrograms/ml. Drug-related renal dysfunction and auditory toxicity occurred in 63% and 44%, respectively, of gentamicin-treated patients and in 43% and 25%, respectively, of tobramycin-treated patients. Mean maximal rises (+/- SEM) in serum creatinine levels were 0.8 (+/- 0.4) mg/dl in the group given gentamicin and 1.6 (+/- 0.7) mg/dl in the group given tobramycin. Mean maximal decreases in pure-tone hearing threshold levels were greater in gentamicin-treated patients (58.3 dB) than in those given tobramycin (22.5 dB). Both forms of toxicity appeared earlier and at a smaller dose with gentamicin than with tobramycin.

Characteristics of left-sided endocarditis due to Pseudomonas aeruginosa in the Detroit Medical Center.
Mortality due to left-sided endocarditis caused by Pseudomonas aeruginosa remains high despite the therapeutic regimen of high doses of an aminoglycoside plus a beta-lactam antibiotic. In this series, left-sided pseudomonal endocarditis presented as an acute illness refractory to optimal antibiotic therapy. Complications associated with active valvular infection, such as neurologic sequelae, ring and annular abscesses, congestive heart failure, and splenic abscesses, are frequent. The overall morbidity and mortality remain high; however, outcome appears to improve with surgery. Our present data suggest that early valve replacement accompanied by a 6-week course of high doses of a combination of drugs may be the optimal therapy for left-sided pseudomonal endocarditis. This approach not only may prevent serious and potentially lethal complications of the disease but also may cure them.
