Current definitions of encapsulating peritoneal sclerosis are practical and clinically relevant. It is important to adhere to a more uniform use of the proper terminology, and it is the recommendation of the authors that EPS be adopted as the more appropriate term. The best literal definition of EPS is based on clinical-pathologic criteria. Differentiation(More)
The objective of this study was to evaluate the association of peritoneal membrane transport with technique and patient survival. In the Canada-USA prospective cohort study of adequacy of continuous ambulatory peritoneal dialysis (CAPD), a peritoneal equilibrium test (PET) was performed approximately 1 mo after initiation of dialysis; patients were defined(More)
OBJECTIVE No studies have been done to examine factors that predict the outcome of bacterial peritonitis during peritoneal dialysis (PD), beyond the contribution of the organism causing the peritonitis, concurrent exit-site or tunnel infection, and abdominal catastrophes. DESIGN In this study we examined several clinical and laboratory parameters that(More)
The optimal target for glycated hemoglobin (HbA1c) has not been well defined in peritoneal dialysis (PD) patients with diabetes mellitus. The objective of our study was to examine the predictive value of predialysis and time-averaged follow-up HbA1c values on technique and patient survival in diabetic PD patients treated in the Toronto General Hospital Home(More)
OBJECTIVE We analyzed residual renal function (RRF) in a large number of new peritoneal dialysis (PD) patients to prospectively define the time course of decline of RRF and to evaluate the risk factors assumed to be associated with faster decline. STUDY DESIGN Single-center, prospective cohort study. SETTING Home PD unit of a tertiary care University(More)
In this paper we examine the relationship of serum levels of Ca, P, Ca X P, P/Mg, Ca X P/Mg, alkaline phosphatase, and iPTH to the development or regression of peripheral arterial calcifications (AC) in 44 patients with end-stage renal disease being treated by continuous ambulatory peritoneal dialysis (CAPD). The average follow-up time of this longitudinal(More)
The aim of this study was to assess the clinical and laboratory correlations of bone mineral density (BMD) measurements among a large population of patients on chronic peritoneal dialysis (PD). This cross-sectional, multicenter study was carried out in 292 PD patients with a mean age of 56 ± 16 years and mean duration of PD 3.1 ± 2.1 years. Altogether, 129(More)
The peritoneal catheter is the CAPD patient's lifeline. Advances in catheter knowledge have made it possible to access the peritoneal cavity safely and maintain access over an extended period of time. Infection at the exit site remains a major problem, a solution for which is being extensively researched. The successful outcome of a catheter in an(More)
The incidence, distribution, and progression of arterial calcification in severe chronic renal disease were studied from 364 skeletal survey examinations in 152 patients (ages 15-60). The incidence increased from 30% in the 15-30 age group to 50% in the 40-50 group. The earliest and commonest site of calcification was the ankles, followed in frequency by(More)
