Selenium depletion in patients on home parenteral nutrition. The effect of selenium supplementation.

Author information

Medical Department A, Rigshospitalet, Denmark.


Severe selenium (Se) depletion was found in nine patients receiving long-term home parenteral nutrition because of short bowel syndrome. Plasma Se ranged from 0-0.51 (median 0.21 mumol/L), and erythrocyte Se ranged from 0.7-2.6 (median 1.8 mumol/gHgb), which was significantly lower than in the controls. Glutathione peroxidase (GSHPx) in plasma and erythrocytes was also decreased. After bolus injections with 200 micrograms Se/d in the form of sodium selenite for 4 mo, followed by 100 micrograms/d for 8 mo, plasma Se increased to values slightly but significantly higher than in the controls. Erythrocyte Se reached normal levels in most of the patients after 4 mo substitution, but it remained lower than in the controls. Following Se supplementation, plasma and erythrocyte GSHPx did not differ between patients and controls. These data suggest that all patients receiving long-term parenteral nutrition because of short bowel syndrome should receive at least 100 micrograms sodium selenite/d when given as bolus injections to avoid Se depletion.
