Zinc metabolism in adrenal cortical insufficiency: effects of carbohydrate-active steroids. 1984

R I Henkin, and D M Foster, and R L Aamodt, and M Berman

Detailed studies of zinc kinetics were performed in two patients with adrenal cortical insufficiency to investigate the effects of carbohydrate-active steroids (CAS) on zinc metabolism. Zinc- 69m was administered intravenously to each patient under two conditions: (1) treated with CAS replacement therapy and (2) untreated, ie, without hormone treatment for five to six days. Radioactivity was measured in blood plasma, red blood cells, urine, and stool and by means of external probes placed over liver and thigh. Data were analyzed using a previously developed multicompartmental model, which describes the early phase of zinc metabolism. The results of these studies suggest that CAS promotes the internalization of zinc into red blood cells and liver cells. These results are consistent with previous in vitro and in vivo studies in which CAS was shown to induce the synthesis of metallothionein in liver cells.
