Serum-selenium concentrations in patients with maple-syrup-urine disease and phenylketonuria under dieto-therapy.
Serum-selenium concentrations were measured in 2 dietetically treated patients with maple-syrup-urine disease, in 11 dietetically treated patients with phenylketonuria, in 37 healthy children of different ages and in 183 healthy adults. The estimations were performed by instrumental neutron activation analysis. The values of the dietetically treated patients were much lower than those of healthy children of the same age group. Within 8 to 12 weeks the serum-selenium concentrations decreased from normal values before therapy to very low values under dieto-therapy. During infancy the serum-selenium concentrations of healthy individuals show an increase to the adult range of values.
