[Long-terme outcome of peritoneal dialysis treatment--27 years of single centre experience].

Abstract

By the end of 2007 we had 160 patients on CAPD treatment in our centre (44% male, 56% female) aged between 29-78 years. Till 1994 13% of our patients were diabetics. In the last 10 years (1997-2007) the percentage of diabetics increased to 36%. During the 27 years period 44% of our patients died, 35% switched to haemodialysis and 3% have undergone renal transplantation. The survival rate after three years of treatment was 75%, after five years 63% and after 10 years 44%. Technique survival was 77%, 65% and 48% respectively. There were 309 episodes of peritonitis as the main complication of treatment (one episode on every 9, 4 months of treatment till 1994 and one episode on every 25, 8 months in the last ten years), out of which 58% was caused by Gram positive bacteria, 18% by Gram negative, 4% were fungal infections while the remaining 20% were culture negative. Regarding other complications we had 42 exit-site infections and 8 episodes of sclerosing peritonitis with 4 deaths. We found peritonitis to be the main reason of switching to haemodialysis (71%) and the main reason of death (39%) among the patients on CAPD. In the last 10 years (1997-2007) we analyzed the diabetics group separately and we found that the rate of CAPD dropout was not significantly different between diabetics and non-diabetics group. However, when analysing the causes of CAPD dropout, we found significant difference in mortality ate (50% among diabetics versus 26% among non-diabetics) and the rate of switching to haemodialysis (37% versus 55% respectively). In addition we established that the rate of CAPD survival was better after 1994 and we speculate that the main reason is the diminished peritonitis rate.
