Abstract
To evaluate the complications of CAPD and their contributing factors in order to improve the patients' survival and reduce morbidity and mortality, we studied records of 65 CAPD patients treated at our hospital from October 1996 to January 2002. There were 32 (49%) males and the mean age of the patients was 48 +/- 16 years. All the patients were on the twin bag CAPD system. The mean duration of follow-up on CAPD was 29 +/- 20 months. There were 75 episodes of complications occurring in the patients with a rate of 0.41 episodes/patient years. Peritonitis was the most frequent and serious complication accounting for 55 episodes with a rate of 0.35 episodes/patient years. Only 51% of the episodes showed positive culture; the organisms included Staphylococcus epidermidis (18.2%), Staphylococcus aureus (3.6%), Pseudomonas (16.4%), E. coli (1.8%), Azadobacter (5.45%) and Serratia (3.6%). All the episodes of infection, except one, responded to treatment but 10 patients had recurrent infection; one patient was cured only after removal of the catheter. There were 12 exit site infection episodes and five catheters were removed due to mechanical and infectious reasons. Three patients were switched to hemodialysis (HD), nine patients were transplanted and 11 patients expired; none died due to peritonitis. We conclude that the mortality rate of the complications on CAPD has declined in the present study compared to our previous report early in the 1990s due mostly to the adoption of the twin bag CAPD system.
