Abstract
The patient survival (PS) and technique survival (TS) were evaluated in 1990 patients on continuous ambulatory peritoneal dialysis (CAPD) (males: 55.9%, mean age +/- SD: 58.4 +/- 14.8 years), treated in 30 centers participating in the Italian PD Study Group, from 1980 to 1989 (follow-up: 3953 years; mean +/- SD: 2.02 +/- 1.86 years). The total PS was 50.7% at 4 years, compared to 73.3% of patients without clinical high-risk condition (HRC) at the beginning of CAPD. In this group (34.0%) PS was significantly higher (p < 0.001) compared, respectively, to patients with cardiovascular disease (30.5%), diabetes (13.1%), and age > or = 70 years (11.2%). The percentage of death reached the mean value of 11.3% per year without any statistically significant tendency to variation during the follow-up, despite the increased number of patients > or = 65 years old and those with HRC (p < 0.001). Cardiovascular diseases (47.3%) and cachexia (17.8%) were the most frequent causes of death, whereas the mortality due to peritonitis showed a progressive increase in patients with peritonitis incidence 1 ep/year (G4) compared to those with < 0.5 ep/year (G2). Peritonitis (0.68 ep/year) was the most frequent cause of technique failure (30.0%), with clinical complications (18.2%) and peritoneal membrane failure (16.4%) as the second and third causes. The dropout percentage was 8.3% per year with a significant decrease over time (p = 0.012) and a positive correlation with the reduction of peritonitis incidence (p = 0.035). The total TS was 50.1% at 7 years, and it was significantly worse in G4 compared to G2.(ABSTRACT TRUNCATED AT 250 WORDS)
