[Comparison of fructosamine, glycosylated hemoglobin and glucose in patients with type II diabetes].

The levels of blood glucose, glycosylated hemoglobin, and fructosamine were measured in 57 patients with type II diabetes in order to elucidate the value of measurements of glycosylated proteins in assessment of the disorders of carbohydrate metabolism. A highly significant correlation between the levels of glucose and fructosamine was revealed (r = 0.81, p < 0.05) and a reliable, though less significant one, between the levels of glucose and glycosylated hemoglobin (r = 0.55, p < 0.05) and those of fructosamine and glycosylated hemoglobin (r = 0.63, p < 0.05). Similarity between correlation coefficients for fructosamine and glucosylated hemoglobin with the mean concentration of glucose during both the first and second preceding months permits an assumption that the degree of metabolic control of carbohydrate metabolism in the examined patients was stable for at least 2 months.
