The vibratory perception threshold in young diabetic patients: associations with glycemia and puberty
JM Sosenko, AJ Boulton, DB Kubrusly, JK Weintraub and JS Skyler
The vibratory perception threshold, an indicator of sensory neuropathy, was
measured in young type I diabetic patients (N = 55) and nondiabetic control
subjects (N = 34) of similar age. Values were significantly higher in the
diabetic patients (P less than 0.01), and 20% had values greater than that
of any control subject. This difference was most marked among those
postpubertal and persisted with allowances for age and gender in an
analysis of covariance. Although the vibratory perception threshold was not
related to hemoglobin A1 in younger diabetic patients (Tanner stage less
than 5), there was a highly significant positive relationship in
postpubertal patients (r = 0.72, P less than 0.001). There were also
associations of the vibratory perception threshold with age in diabetic and
control subjects (r = 0.44 and r = 0.43, respectively, P less than 0.01 for
both) and with diabetes duration (r = 0.36, P less than 0.01). These data
indicate that vibratory perception threshold abnormalities occur early in
the course of type I diabetes mellitus; however, they are more evident in
those patients who are postpubertal. In addition, they suggest that the
association between the vibratory perception threshold and glycemia may be
modified by developmental factors.
