Abstract
Objective
To evaluate the use of the combination of cefazolin and ceftazidime for initial treatment of peritoneal dialysis (PD)-related peritonitis in pediatric patients.
Design
Retrospective nonrandomized study.
Setting
Pediatric dialysis units of the University Medical Center of Utrecht and Nijmegen, The Netherlands.
Patients
40 children (median age 5.4 years) who were treated with PD during the study period of 4.5 years.
Interventions
All 50 episodes of peritonitis that occurred during the study period were evaluated by review of medical records. Patients were given intraperitoneal ceftazidime 500 mg/L dialysis fluid, and cefazolin 500 mg/L as a loading dose, followed by a maintenance dose of ceftazidime 125 mg/L and cefazolin 100 mg/L, intraperitoneally, 4 times daily. Antibiotics were continued for 14 days.
Results
After identification of the causative microorganism, one of the antibiotics was discontinued in 34 cases, and the antibiotic schedule was adapted in 2 cases. All cases were initially cured within 3 days. In 5 cases (10%), there was a peritonitis with the same organism recurring within 2 weeks after completion of treatment. There were 4 cases of PD-related peritonitis caused by pseudomonas, all of which were cured.
Conclusions
The antibiotic combination of cefazolin and ceftazidime is effective for the initial therapy of PD-related peritonitis in children. The toxic complications of aminoglycosides are avoided with this combination.
