title: Calcium alpha-ketoglutarate administration to malnourished hemodialysis patients improves plasma arginine concentrations.
abstract: Calcium alpha-ketoglutarate administration to 24 malnourished hemodialysis patients for 1 year leads to a significant increase in plasma concentrations of L-arginine from 53.6 +/- 18.3 (compared to a healthy control group: 87.5 +/- 27.3) to 71.1 +/- 15.9 mumol/l (p < 0.05). Furthermore, concentrations in plasma of proline and histidine, precursors of glutamate biosynthesis, are increased; inorganic phosphate and urea are significantly decreased in hemodialysis patients after 1 year of calcium alpha-ketoglutarate administration.
