Background

Cardiovascular diseases are the most important cause of mortality in hemodialysis (HD) patients. The aim of the study was to evaluate the relationship between serum asymmetric dimethylarginine (ADMA), apelin-13 levels, and mortality in HD patients.

Methods

The study comprised a total of 122 patients receiving HD thrice weekly. Baseline pre-dialysis blood samples were collected and stored at −80°C. Serum ADMA and apelin-13 were measured by ELISA. During the 2-year follow-up, patients who died due to all causes were recorded. Demographic features, baseline biochemical values, ADMA, apelin-13, and other inflammation markers of patients who died and were living were compared at the end of the second year.

Results

During two-year follow-up, 26 patients under HD treatment died. Patients who died and were living were compared. The patients who died were older (P<0.001), their apelin-13, albumin, and phosphorus levels were lower (P=0.007, P=0.025, P=0.031), and LDL-c levels and coronary artery disease rates were higher (P=0.027, P=0.020). Apelin-13 levels were 58.0 (46.0-130.8) ng/L in the patients who died and 121.6 (64.6-182.9) ng/L in the living patients. The ADMA levels of the patients who died were lower but not statistically significant (P=0.070). In univariate logistic regression analysis, age, phosphorus, apelin-13, neutrophil/lymphocyte ratio (NLR), and albumin levels were found to be related to mortality. In multivariate logistic regression analysis, age, phosphorus, apelin-13, and NLR were determined as independent variables in predicting mortality (P=0.007, P=0.016, P=0.017, and P=0.031, respectively).

Conclusion

ADMA did not show significant predictive value, suggesting heterogeneity among endothelial dysfunction markers in HD.
