Trace Element Status of Chronic Renal Patients Undergoing Hemodialysis

Abstract

The purpose of this study was to examine the status of trace elements (Cu, Zn, and Fe) and minerals (Mg, K, Na, and Cl) and the level of biochemical parameters (urea, creatinine, total protein, albumin, and glucose) in hemodialysis (HD) patients. This study included 30 HD patients (25 men and 5 women) aged 52.12 +/- 3.13 years and 30 healthy subjects (23 men and 7 women) aged 51.64 +/- 2.22 years. This study investigated the status of trace elements and minerals in HD patients. It was found that the total HD patients (before and after dialysis) had statistically lower Zn and albumin in the after-dialysis group K and Cl levels and higher Mg, creatinine, and urea in the before-dialysis group K and in the after-dialysis group glucose levels than those of the controls. It was determined that the results might be helpful in monitoring patients with renal failure in terms of insufficiency or excess of trace elements and minerals. There was positive correlation for Mg-K (r=0.64; p=0.001), creatinine-urea (r=0.59; p=0.001), K-urea (r=0.56; p=0.001), K-creatinine (r=0.52; p=0.003), Mg-creatinine (r=0.47; p=0.008), Zn-albumin (r=0.40; p=0.028), and Zn-creatinine (r=0.40; p=0.031) in the before-dialysis session. There was also positive correlation for creatinine-urea (r=0.56; p=0.001), K-urea (r=0.39; p=0.035), and Mg-creatinine (r=0.38; p=0.041) in the after-analysis session. As a result of the analysis of regression between serum levels of albumin and zinc in total HD patients, the use of the level of albumin might be a suitable choice in determining zinc deficiency resulting from the decrease in the level of zinc in parallel to that of albumin. The results also suggest that the relationship between creatinine and K, Mg, and Zn could be ascribed to the loss of renal function.
