Abstract: The objective of the work was to study the survival peculiarities ofend-stage renal disease patients treated with continuous ambulatory peritoneal dialysis (CAPD) depending on the nutritional status and informative markers associated with it. Methods. 105 ESRD patients who received CAPD treatment during 2012 - 2017 years at the Kyiv Scientific and Practical Center of Nephrology and Dialysis, which is the clinical base of the State Institution "Institute of Nephrology National Academy of Medical Sciences of Ukraine" were included in the cohort prospective open study. The survival analysis was carried out both in the studied population as a whole and in groups depending on the nutritional status (NS) indicators defined basing on the calculation of the subjective global assessment (SGA) points: the first group (n = 51) consisted of patients without malnutrition, the second group (n = 30) - patients with a mild degree of malnutrition, the third group (n = 13) - patients with a moderate degree of malnutrition, and the fourth group (n = 11) - patients with a severe degree of malnutrition. The survival analysis was conducted both in the groups in compliance with NS, and depending on the informational markers associated with NS, in particular, albumin, body mass index (BMI), residual renal function (RRF). Survival were calculated using the Kaplan-Meier method, and the difference between survival rates was analyzed using the log-rank test and χ². The starting date of peritoneal dialysis treatment was considered as the starting point of the monitoring. The difference was considered to be accurate at p 24 kg/m2 was apparently higher than those with an indicatorBMI ≤ 24 kg/m2, and it was in 1 and 3 years 94% vs 86% and 79% vs 47%, respectively (p = 0.00321, log-rank test). Veritable differences have been registered in the cumulative frequencies of survivors depending on RRF value: the survival rate was significantly higher among patients with RRF ≥ 5 ml/min/1.73 m² and significantly lower among patients with RRF
