Faster Transport Status and Mortality in Anuric Patients Undergoing Continuous Ambulatory Peritoneal Dialysis.


PMID 26278549

Abstract

There are limited data regarding the relationship between transport status and mortality in anuric continuous ambulatory peritoneal dialysis (CAPD) patients. According to the dialysate to plasma creatinine ratio (D/P Cr), 292 anuric CAPD patients were stratified to faster (D/P Cr ≥0.65) and slower transport groups (D/P Cr <0.65). The Cox proportional hazards models were used to evaluate the association of transport status with mortality. During a median follow-up of 22.1 months, 24% patients died, 61.4% of them due to cardiovascular disease (CVD). Anuric patients with faster transport were associated with an increased risk of all-cause mortality (HR (95% CI) = 2.16 (1.09-4.26)), but not cardiovascular mortality, after adjustment for confounders. Faster transporters with pre-existing CVD had a greater risk for death compared to those without any history of CVD. Faster transporters were independently associated with high all-cause mortality in anuric CAPD patients. This association was strengthened in patients with pre-existing CVD.
