[Zinc level in the blood of children with nephrotic syndrome and correction of its deficiency with animal blood preparation Livex].

Serum and erythrocyte zinc levels have been assayed in in 45 children with steroid-dependent nephrotic syndrome in both acute phase and remission. Out of these children a group of 22 has been distinguished. These patients have been treated with Livex--animal blood preparation containing amino acids and trace elements, including zinc. It was found, that serum zinc has been significantly lowered in children with the acute phase of nephrotic syndrome who were not treated with Livex. Erythrocyte zinc levels have been normal in these patients. A significant increase in both serum and erythrocyte zinc levels has been noted during remission, but they have still been lower that in healthy children. A three-month cure with Livex produced statistically significant increase in zinc levels in children during remission.
