Evidence of beneficial effects of strict glycemic control on diabetic vascular complications--a prospective study with artificial devices.

This prospective study was undertaken to examine whether glycemic normalization could have beneficial on the course of diabetic vascular complications in 6 insulin-dependent diabetics. A significant amelioration of glycemic regulation was achieved by intensive glycemic control with artificial devices and multiple injections for 3 months, which also resulted in an improvement in conduction velocity, a regression in retinovascular permeability and a decrease in urinary total protein excretion. These results indicate that even after short-term treatment, glycemic near-normalization can have a beneficial effect on the early stage of diabetic vascular complications.
