Glucose variability not a risk factor for neuropathy
45th Annual Meeting of the European Association for the Study of Diabetes
Glucose variability does not appear to be an additional risk factor for the development of diabetic neuropathy, researchers suggested here.
Using data from the Diabetes Control and Complications Trial (DCCT), researchers in The Netherlands and United Kingdom assessed glycemic variability as a risk factor for the development of peripheral or autonomic diabetic neuropathy. Seven-point glucose profiles were collected four times per year during the DCCT among 1,441 patients with type 1 diabetes. The researchers assessed peripheral neuropathy at baseline and four years follow-up.
Glucose variability had no effect on the incidence of clinical neuropathy confirmed by autonomic or electromyography abnormalities (OR=1.07; 95% CI, 0.83-1.35) or clinical neuropathy alone (OR=0.95; 95% CI, 0.77-1.18).
While glucose variability appeared to have an effect on overall autonomic dysfunction, the effect did not remain when adjusting for HbA1c or mean glucose.
"With respect to the prevention of diabetic neuropathy, we recommend to maintain the focus at achieving overall better glycemic control," Sarah Siegelaar, MD, of the department of internal medicine at Academic Medical Center of the University of Amsterdam, told Endocrine Today. - by Katie Kalvaitis
