Abstract
Introduction: We aimed to examine the clinical characteristics of peritoneal dialysis (PD) patients with different baseline peritoneal transport characteristics and the effect of peritoneal transport characteristics on the prognosis of PD patients.
Methods: Patients who received PD for more than 3 months were included. Clinical characteristics, risk factors for high peritoneal transport, and risk factors for death and technique failure were examined. All patients were treated with glucose-containing peritoneal dialysis solution, and the peritoneal dialysis protocol was either day ambulatory peritoneal dialysis (DAPD) or continuous ambulatory peritoneal dialysis (CAPD).
Results: A total of 351 patients were enrolled, comprising 70 in the low transport group, 149 in the low average transport group, 88 in the high average transport group, and 44 in the high transport group. Multivariate logistic regression analysis showed that a high Charlson's comorbidity index (CCI) and low albumin were risk factors for a high baseline transport status. In the nonhigh transport group, the proportion of patients with albumin less than 30 g/L, who developed high transport status, was higher than those with albumin more than 30 g/L (P = .029). The survival rate in the high transport group was significantly lower than that in the other three groups (P < .001). Multivariate Cox regression analysis showed that age, systolic blood pressure, CCI, C-reactive protein (CRP) and high transport were independent risk factors for all-cause mortality. Male sex, triglycerides and CRP were independent risk factors for technique failure.
Conclusion: High peritoneal transport status is an independent risk factor for death. High CCI and low albumin are determinants of baseline high peritoneal transport. To avoid development of a high transport state, serum albumin should be increased to more than 30 g/L. DOI: 10.52547/ijkd.7617.
期刊介绍：
The Iranian Journal of Kidney Diseases (IJKD), a peer-reviewed journal in English, is the official publication of the Iranian Society of Nephrology. The aim of the IJKD is the worldwide reflection of the knowledge produced by the scientists and clinicians in nephrology. Published quarterly, the IJKD provides a new platform for advancement of the field. The journal’s objective is to serve as a focal point for debates and exchange of knowledge and experience among researchers in a global context. Original papers, case reports, and invited reviews on all aspects of the kidney diseases, hypertension, dialysis, and transplantation will be covered by the IJKD. Research on the basic science, clinical practice, and socio-economics of renal health are all welcomed by the editors of the journal.
