The modality of dialysis does not influence atheromatous vascular disease progression or cardiovascular outcomes in dialysis patients without previous cardiovascular disease.

Background: There is limited and inconclusive information regarding the influence of the modality of renal replacement therapy on the atherosclerotic burden of patients on dialysis. The aim of this study was to compare the prevalence of asymptomatic atheromatous carotid disease, as also its rate of progression and cardiovascular outcomes, in two matched populations of patients treated with hemodialysis (HD) and peritoneal dialysis (PD).

Methods: Following a prospective, observational and multicenter design, we compared 237 PD and 237 HD patients without previous cardiovascular disease, included in the NEFRONA study, and matched for age, sex, diabetes and time on dialysis.

Low Serum Levels of Vitamin D are Associated with Progression of Subclinical Atherosclerotic Vascular Disease in Peritoneal Dialysis Patients: A Prospective, Multicenter Study.

Background: The prevalence of subclinical atherosclerosis and the main predictors of progression of this condition in patients undergoing peritoneal dialysis (PD) have been insufficiently investigated.

Objectives And Method: Following a prospective, multicenter, observational design, we studied 237 patients who were treated with PD for ≥3 months, without any clinical background of cardiovascular (CV) disease. Our objectives were the following: (1) to investigate the prevalence of subclinical atherosclerosis, as compared to a control group of age- and sex-matched healthy individuals, and (2) to disclose PD technique-related predictors of progression of disease during a 24-month follow-up period.

Baseline Residual Kidney Function and Its Ensuing Rate of Decline Interact to Predict Mortality of Peritoneal Dialysis Patients.

Background: Baseline residual kidney function (RKF) and its rate of decline during follow-up are purported to be reliable outcome predictors of patients undergoing Peritoneal Dialysis (PD). The independent contribution of each of these factors has not been elucidated.

Method: We report a multicenter, longitudinal study of 493 patients incident on PD and satisfying two conditions: a glomerular filtration rate (GFR) ≥1 mL/minute and a daily diuresis ≥300 mL.

Incremental peritoneal dialysis: Clinical outcomes and residual kidney function preservation.

Introduction: Initiation of peritoneal dialysis (PD) with 3 exchanges has become common practice in recent years, despite the lack of published clinical data.

Objective: To describe experience with incremental peritoneal dialysis (IPD) at a single site.

Material And Methods: A total of 46 IPD patients undergoing 2-year clinical, laboratory, treatment and progression follow-up.

Compared decline of residual kidney function in patients treated with automated peritoneal dialysis and continuous ambulatory peritoneal dialysis: a multicenter study.

Background: There is controversy concerning the compared rates of decline of residual kidney function (RKF) in patients treated with continuous ambulatory peritoneal dialysis (CAPD) and automated peritoneal dialysis (APD).

Objectives And Method: Following an observational, multicenter design, we studied 493 patients initiating peritoneal dialysis (PD) in four different Spanish units. We explored the effect of the PD modality on the rate of decline of RKF and the probability of anuria during follow-up.

[Results of the cooperative study of Spanish peritoneal dialysis registries: analysis of 12 years of follow-up].

Introduction And Objectives: There is currently no registry that gives a complete and overall view of the peritoneal dialysis (PD) situation in Spain. However, a report on PD in Spain was developed for various conferences and meetings over several years from data provided by each registry in the autonomous communities and regions. The main objective of this study is to analyse this data in aggregate and comparatively to obtain a representative sample of the Spanish population on PD in recent years, in order that analysis and results in terms of demographic data, penetration of the technique, geographical differences, incidence and prevalence, technical aspects, intermediate indicators, comorbidity, and outcomes such as patient and technique survival may be extrapolated to the whole country.
