The Predictive Value of KT/V and Peritoneal Solute Transport in CAPD Patients is Dependent on the Type of Comorbidity Present

Abstract

Comorbidity, age, dialysis dose (KT/Vurea)’ plasma albumin, and peritoneal function (DIP treat) were measured cross-sectionally in 228 continuous ambulatory peritoneal dialysis (CAPD) patients, who were then followed up for a mean of two years. Comorbidity, utilizing a semiquantitative score described previously, was the most powerful predictor of mortality in both univariate and multivariate analysis. Using univariate analysis, all the variables predicted outcome with statistical significance, mortality being associated with lower KT/V and plasma albumin and a higher DIP treat On multivariate analysis only comorbidity, age, and KT/V remained independent predictors.

Data was further analyzed on the basis of type of comorbid condition. In those patients without comorbid disease (n = 127) neither KT/V, albumin nor DIP
