Özet

Background: The relationship between hypoalbuminemia in peritoneal dialysis (PD) and mortality,

risk of peritonitis, and decreased residual renal function (RRF) is known. However, we have

not encountered a comprehensive study on which of the mean albumin values, at the beginning

of peritoneal dialysis, in the first year, and during the peritoneal dialysis period, provide more

predictive predictions regarding mortality, peritonitis risk, and RRF reduction.

Methods: A total of 407 PD patients in whom PD was initiated and followed up and PD was terminated

were included in the study. Albumin levels, peritonitis, and RRF at the beginning of PD

and at 3-month periods during PD were recorded.

Results: In the evaluation of the patients, there was a significant relationship between mean,

first-year albumin values in RRF loss (p¼0.001, p¼0.006, respectively) and peritonitis (p<0.001),

but no significant correlation was found with baseline albumin values (p¼0.213, p¼0.137,

respectively). In the comparison of mortality ROC analysis of PD patients, a significant correlation

was found with mortality at baseline, first year, and mean albumin values (p<0.001). However,

in the multivariate Cox regression analysis, it was determined that there was a more significant

relationship between first-year albumin and mean albumin values compared to baseline albumin

values (HR 0.918 [95% CI 0.302–0.528] (p<0.001)), (HR 1.161 [95% CI 0.229–0.429] (p<0.001)),

(HR 0.081 [95% CI 0.718–1.184] (p¼0.525)).

Conclusions: In conclusion, mean and first-year mean albumin levels provide more determinative

predictions for mortality, risk of peritonitis, and maintenance of residual renal functions in

peritoneal dialysis patients compared to baseline albumin.
