Factors associated with nutritional status in peritoneal dialysis patients

Abstract

The aim of our study was to examine the relationship between nutritional status (NS) in patients undergoing continuous ambulatory peritoneal dialysis (CAPD) and dialysis-related factors.Methods. 105 patients who were treated by CAPD were included in this observational study. To assess the NS we determined the level of serum albumin, body mass index (BMI) and subjective global assessment (SGA). The study was carried out in two stages. At the first stage of the work PD patients’ nutrition status was examined. For further analysis, the patients were divided into four groups according to the condition of the NS: the first group (n = 54) consisted of patients without disturbance of nutrition, the second (n = 27) with mild nutrition disorders, the third (n = 13) - with an average degree and the fourth (n = 11) with a severe degree of malnutrition. At the second stage of the work specialty of the nutritional status and residual renal function, frequency of PD-peritonitis, transport characteristics of the peritoneum were studied.Results. Nutritional disorders were observed in 54 (51.4 %) patients. A mild malnutrition was diagnosed in 28.7 % of patients, medium and severe in 12,38 % and 10,48% of patients, respectively. Parameters of NS, except BMI, were higher in patients without nutrition disorders (ND) comparing with the patients who had it. RRF was higher in patients without ND; but anuria was observed practically in all patients with severe ND. We receive direct relationship between the level of serum albumin and RRF (r = 0.53; p
