Serum trace element concentrations and iron metabolism in allogeneic bone marrow transplant recipients.
Serum trace element concentrations, parameters of iron metabolism and serum protein concentrations were investigated in thirteen adult recipients of bone-marrow transplants receiving total parenteral nutrition. Six of the patients died during the four weeks follow-up. Serum zinc concentrations were initially low but increased during the treatment. They also tended to be lower in dying patients than in survivors. Concentrations of serum copper and selenium remained unaltered. Serum iron started to increase during the preconditioning and remained raised for three weeks. No significant changes occurred in serum transferrin levels. Transferrin saturation increased during the preconditioning and started to return to normal after day +14. Serum ferritin was greatly raised from the start and increased further during the procedure. Routine trace element substitution seemed to be sufficient during total parenteral nutrition with the possible exception of zinc. A return to normal transferrin saturation after day +14 may be an early favourable sign that the graft is taking and hematopoietic recovery commencing.
