Incidence of CAPD peritonitis in patients using UVXD or O-set systems.

Abstract

Eighty-one patients were placed either on the O-set (39) or the UVXD germicidal system (42). Total experience was 13.7 +/- 8.0 and 17.8 +/- 14.8 months, respectively. There were 48 and 85 new episodes of peritonitis in 24 and 28 patients, respectively, and an additional 11 and 28 episodes of relapse or probable relapse. The peritonitis rate was 1 episode each 11.14 and 8.83 patient months, which was not significantly different. There was no significant difference between the 2 groups in terms of the mean numbers of peritonitis-free days (393.7 versus 503.8) or in the mean time to the first episode of peritonitis (6.60 versus 6.54 months). The odds ratio of relative risk of peritonitis with the two systems was 1:1.17 (O-set:UVXD). There appears to be no difference in ability of the two systems to prevent peritonitis.
