Abstract

Introduction: Hemodialysis patients are at risk of developing trace elements imbalance and increase in heavy metals. Objective: The objective of this study was to asses plasma levels of copper, zinc, selenium, cadmium and lead of hemodialysis patients. Design: The study comprised 40 patients aged 27-65 years under regular hemodialysis for 1.8-13 years and 28 healthy age and sex matched the control. Copper, zinc, selenium, cadmium and lead plasma levels were determined by atomic absorption spectrophotometry. Results: Levels of copper, zinc and selenium were significantly decreased in dialysis patients compared with the control group; the percentage decrease was 25.5%, 20.4% and 19.0% for copper zinc and selenium, respectively. Moreover, cadmium and lead plasma levels showed significant increases among hemodialysis patients versus their matched controls with percentage of 144.6% and 28.1% for cadmium and lead, respectively. Conclusions: Levels of trace elements are altered and heavy metals showed increased plasma levels by hemodialysis. Regular monitoring of trace elements and heavy metals in hemodialytic patients is advisable.
