title: [Metabolism of B group vitamins in patients with insulin-dependent and non-insulin dependent forms of diabetes mellitus].
abstract: Metabolism of vitamins B, involving evaluation of these vitamins content in blood and excretion of their metabolites with urine, was studied in adult healthy persons as well as in patients with insulin-dependent and -independent forms of diabetes mellitus. Distinct alterations in metabolism of vitamin B2 were detected in the insulin-dependent diabetes: its content in erythrocytes and the rate of excretion with urine were increased. This phenomenon made some problems in evaluation of riboflavin consumption in patients with diabetes mellitus of the I type, while parameters of vitamin consumption in insulin-independent diabetes were similar to those of healthy persons. Parameters of metabolism of vitamins B1, B6 and PP were not different in patients with insulin-dependent and -independent forms of diabetes mellitus. Rates of excretion of 4-pyridoxic acid, 1-methyl nicotinamide, thiamine with urine as well as concentration of the corresponding vitamins in blood were similar to those parameters of healthy persons.
