Abstract

Since less attention has been paid to the effect of passing blood pressure states on the survival of peritoneal dialysis (PD) patients, this study aimed to inves­tigate the survival of PD patients with and without hypertension, estimate the probability of hypertension and determine the influential factors. In this retro­spective cohort study, the data of 700 patients visiting dialysis centers from all provinces of Iran from 1997-2009 were analyzed. For data analysis, the multistate survival model was used. The median survival time (months) and five-year survival were 75% and 56%, respectively. Males had a higher probability of hypertension (63%) than females (52%). The risk of death in normotensive patients increased with age and fast blood sugar (FBS) (age: HR = 1.02, p-va­lue <0.001; FBS: HR = 1.03, p-value = 0.034) and decreased with increasing albumin (HR = 0.60, p-value = 0.015). When experiencing hypertension, the death risk increased with age (age: HR = 1.03, p-value<0.001); also, higher serum albumin and blood urea nitrogen (BUN) had a protective effect against mortality (albumin: HR = 0.66, p-value = 0.038; BUN: HR = 0.99, p-value = 0.014). Paying attention to age, obesity, and blood sugar in PD patients seems necessary.
