title: Treatment and prevention of relapses of CAPD Pseudomonas peritonitis.
abstract: Pseudomonas peritonitis in continuous ambulatory peritoneal dialysis (CAPD) can be difficult to eradicate, because it is frequently resistant to common antibiotics, inducing the loss of the peritoneal cavity in some cases. A total of 14 episodes of Pseudomonas peritonitis in 12 patients (6 male, 6 female) were treated with intraperitoneal (IP) administration of a combination of ceftazidime and tobramycin. All patients were hospitalized. The loading doses were 1000 mg/2 L of ceftazidime and 1.7 mg/kg of tobramycin, and the maintenance IP doses were 250 mg/2 L of ceftazidime and 16 mg/2 L of tobramycin. The therapy duration was 14 days. In 7 episodes (group A) no other antibiotic regimen was provided, while in the remaining 7 episodes (group B) therapy was continued with 500 mg b.i.d. of oral ciprofloxacin for the next 14 days. Pseudomonas species isolated in group A were P. alcaligenis (1), P. putida (1), P. maltophilia (1), R. cepacia (1), and unidentified (3). In group B the following Pseudomonas species were isolated: P. aeruginosa (4), P. diminuta (1), P. stutszeri (1), and unidentified (1). Recurrence of peritonitis was seen in 4 episodes of group A with 2 catheter removals, while all episodes were cured in group B. These results suggest that IP ceftazidime and tobramycin with the additional use of oral ciprofloxacin is successful in the treatment and prevention of relapses of Pseudomonas peritonitis.
