[Effects of vitamin D on protein turnover in children with renal osteopathy]

Amino acid analysis and investigation of nitrogen balance were done in 2 groups of the patients with renal failure and osteodystrophy on the diet and vitamin D treatment. The results of the investigations confirm vitamin D influence on free amino acid turnover. We observed significant elevations of plasma amino acids in patients treated with the diet and vitamin D in comparison with the patients without vitamin D supplementation. Vitamin D didn't influence on the retention, urinary and fecal excretion of endogenous nitrogen in patients with renal failure
