Objective: To determine whether changing the transfer set on completion of antibiotic treatment for peritonitis affects the rate of relapsing peritonitis.
Methods: This randomized prospective study conducted in a renal unit in Hong Kong recruited all continuous ambulatory peritoneal dialysis (CAPD) patients who developed peritonitis and were successfully treated between August 2001 and October 2002. Exclusion criteria were tuberculosis or fungal peritonitis, relapsing peritonitis, peritonitis coexisting with exit-site or tunnel infection, and antibiotics due to infection of other origin. Patients were randomized to either transfer set change (Group I) or no transfer set change (Group II) on completion of antibiotic treatment.
Results: A total of 38 patients were recruited in Group I and 33 patients in Group II. The two groups were comparable for demographic data, duration of CAPD, and culture results. There were two episodes of relapsing peritonitis in both groups. There was no significant difference in relapsing peritonitis rates between patients who had the transfer set changed and those who did not have the transfer set changed.
Conclusions: Changing the transfer set on completion of antibiotic treatment for peritonitis does not reduce the relapsing peritonitis rate. This practice of transfer set change after antibiotic treatment may not be necessary to prevent relapsing peritonitis.
Key words: continuous ambulatory peritoneal dialysis, relapsing peritonitis, transfer set
