Plasma sorbitol dehydrogenase in diabetic subjects with or without vascular complications.

ABSTRACT

Plasma Sorbitol Dehydrogenase levels were determined in subjects with diabetes mellitus and normal people. The diabetic subjects had circulating plasma levels of SDH significantly higher (p less than 0.001) than those observed in controls. Moreover, the diabetics with vascular complications presented the highest SDH values. The lack of positive correlation between plasma glucose and SDH levels suggests that SDH, like hemoglobin A1C, reflect the degree of previous metabolic control of diabetes mellitus.
