SIMILAR PERITONITIS OUTCOME IN CAPD AND APD PATIENTS WITH DIALYSIS MODALITY CONTINUATION DURING PERITONITIS

As few data exist on treatment of peritonitis in patients on automated peritoneal dialysis (APD), and as pharmacokinetics of several antibiotics are reported to be unfavorable in APD, some favor switching to continuous ambulant PD (CAPD) while treating APD-related peritonitis. We explored whether treating peritonitis with patients continuing their usual PD modality had an effect on outcome. We performed a retrospective analysis of the 508 episodes of PD-associated peritonitis seen in 205 patients in our center from January 1993 to January 2007. During this period, the standard initial therapy for PD-related peritonitis was a combination of intraperitoneal gentamicin and rifampicin. There was no difference in cure rate between CAPD and APD groups. Likewise, initial and maximal leukocyte counts in the PD fluid (PDF), relapse rates, catheter removal rates, and death during treatment of peritonitis were similar in the CAPD and APD groups. Median (interquartile range) duration of elevated leukocyte count in PDF was longer in APD: 5.0 (3.0 - 9.0) days versus 4.0 (2.5 - 7.0) days in CAPD (p
