The impact of peritonitis on CAPD results was evaluated in 1990 pts (mean age +/- SD:58.4 +/- 14.8 yrs, 55.9% males), treated in 30 centres participating in Italian PD Study Group, during 1980-89, with an overall observation period of 3953 years (mean +/- SD 24.1 +/- 22.3 months).

Peritonitis accounted for 24.2% of hospitalization causes and for 6.7% and 30.0% of death and of drop-out respectively. The probability of death and drop-out was significantly high (p < 0.001) in pts with a peritonitis incidence > 1 ep/year than in those with < 0.5 ep/year.

Abstract
The impact of peritonitis on CAPD results was evaluated in 1990 pts (mean age +/- SD:58.4 +/- 14.8 yrs, 55.9% males), treated in 30 centres participating in Italian PD Study Group, during 1980-89, with an overall observation period of 3953 years (mean +/- SD 24.1 +/- 22.3 months). The incidence of peritonitis decreases from 1.21 (1980-84) to 0.48 (1985-89) ep/year (overall:0.68) with a significant (P < 0.001) reduction of the probability of developing the first peritonitis episode (FPE) through the same periods. The probability of developing FPE and the relative risk of peritonitis were significantly lower (P < 0.001) in pts for whom CAPD has been the first treatment (80.1%); on the contrary these parameters did not gain significant difference according to sex, age 65 years, diabetes or cardiovascular disease. As far as the organisms responsible for peritonitis are concerned a significant reduction of S. epid. and an increase of S. aureus, other Gram pos. and Pseudomonas was observed in the second 5-yr periods. Peritonitis episodes caused catheter removal in 8.2% of cases and were associated with catheter infection in 10.8% of cases. Peritonitis accounted for 24.2% of hospitalization causes and for 6.7% and 30.0% of death and of drop-out respectively. The probability of death and drop-out was significantly high (p < 0.001) in pts with a peritonitis incidence > 1 ep/year than in those with < 0.5 ep/year. The probability of drop-out due to peritonitis was not higher in diabetic or older patients.
