CHANGES OF NONESSENTIAL TRACE ELEMENTS LEVELS IN WHOLE BLOOD OF END STAGE RENAL DISEASE ADULT PATIENTS

Aims: Accumulation of trace elements occurs in conditions of decreased or termination of kidneys functions. In some conditions increased trace elements can obtain toxic features. On other hand, researches are showing that concentration of some trace elements could be decreased in ERSD patients, too. The most important factor affecting trace element concentration in ERSD patient is the degree of renal failure and using of replacement therapy. Materials and methods: We determined the concentration of microelements (beryllium, boron, aluminum, vanadium, chromium, nickel, arsenic, rubidium, strontium, cadmium, cesium, barium, thallium and lead) in whole blood of 41 ESRD patients with chronic kidney disease stage VD, who were treated with hemodialysis / hemodiafiltration and in 61 conditionally healthy donors. Determination of whole bloods trace elements content was conducted using inductive coupled plasma mass- spectrometry (ICPMS). Results: It is determinate that levels of beryllium, boron, aluminum, vanadium, chromium, strontium, cadmium, barium, thallium and lead is reliable increased in ESRD patients. Decreased levels are observed for nickel, arsenic, cesium and rubidium. Conclusions: ESRD is accompanied with substantial and multidirectional changes of trace elements blood levels. During researches has shown that in ESRD patients processes of trace elements accumulation are prevailing over elimination ones.
