Abstract:
Three bed-ridden patients who had had only one kind of enteral nutrition without sufficient copper element during a few years showed very low levels of serum copper. Two of them also had leukopenia. The abnormal findings disappeared after the feeding nutrients rich in copper element. The leukopenia may have been due to copper deficiency rather than zinc deficiency. We confirmed that long-term parenteral nutrition must contain trace elements, for example copper.
