Abstract

Background: Aluminum (Al) contamination of parenteral nutrition (PN) solutions remains a concern for long-term PN patients. Al accumulates particularly in bone. Excessive exposure to Al may result in increased Al body burden and impaired bone formation and mineralization, leading to bone disease. Although the U.S. Food and Drug Administration (FDA) has limited Al contamination in large-volume parenteral solutions, small-volume parenterals may still contribute considerable amounts of Al to PN solutions. The goal of this study is to determine whether or not long-term adult PN patients remain at risk for increased bone Al accumulation. Methods: We measured Al accumulation in autopsy bones from 7 patients who had received PN for 2-21 years and compared bone Al levels with those in living control patients undergoing hip or knee replacement. Electrothermal atomic absorption spectrometry was used for bone Al measurements. Results: When compared with bone Al content in controls, markedly elevated Al levels (P
