Infant Parenteral Nutrition Remains a Significant Source for Aluminum Toxicity

Area of Science:

• Neonatal Medicine
• Clinical Chemistry
• Toxicology

Background:

• Aluminum toxicity poses risks including anemia, bone defects, and liver disease.
• Aluminum is a common contaminant in parenteral nutrition (PN), particularly for infants.
• Assessing aluminum levels in infant PN is crucial for patient safety.

Purpose of the Study:

• To evaluate current aluminum contamination levels in infant PN.
• To identify potential sources and correlations of aluminum in PN formulations.
• To compare measured aluminum levels with established safety guidelines.

Main Methods:

• Collected 30 discarded infant PN samples from a neonatal intensive care unit.
• Analyzed aluminum content using inductively coupled plasma mass spectrometry.
• Compared aluminum levels with PN components using regression and ANOVA.

Main Results:

• Mean aluminum contamination was 14.02 mcg/kg/d, exceeding the <5 mcg/kg/d FDA guideline.
• Significant correlations found between aluminum and calcium gluconate (P < .0001) and phosphate (P = .05).
• No association observed between aluminum levels and infant weight in this cohort.

Conclusions:

• Infant PN exhibits aluminum contamination significantly above recommended levels.
• Calcium gluconate and phosphate are likely contributors to aluminum contamination.
• Further research is needed to pinpoint sources and reduce aluminum in infant PN.
