Summary

Chronic kidney disease (CKD) is associated with alterations in the balance of trace elements and metals, which may result from reduced dietary intake, impaired renal function, dialysis-related removal, or environmental exposure. Hemodialysis may play a relevant role in both the removal and potential introduction of these elements. This pilot study aims to investigate trace element and metal imbalances in older patients with advanced CKD and to assess the influence of bicarbonate hemodialysis and dialysis-related environmental exposure on their elemental profile.
