Abstract
Continuous ambulatory peritoneal dialysis is an important modality of therapy for patients with renal disease. However, peritonitis continues to be a major risk factor and is usually treated by intraperitoneal administration of antimicrobial agents. Few data are available concerning the stability of antimicrobial agents in peritoneal dialysis solution beyond 48 h. Our investigation was designed to establish the chemical and biological stability of gentamicin alone and in combination with cefazolin in peritoneal dialysis solution at 6 and 72 h by an immunoassay and by an in vitro bactericidal test against American Type Culture Collection (Rockville, Md.) strains of Pseudomonas aeruginosa, Staphylococcus aureus, and Staphylococcus epidermidis. In addition, uninfected peritoneal dialysis effluent was inoculated with three American Type Culture Collection strains and gentamicin or imipenem. Gentamicin alone or in combination with cefazolin was not altered chemically and was bactericidal for Staphylococcus spp. but not P. aeruginosa. In contrast, imipenem was active against both Staphylococcus spp. and P. aeruginosa. Undefined factors other than inactivation of gentamicin may be responsible for the lack of bactericidal activity and treatment failure of Pseudomonas infections.
