Abstract

The aim of the study was to determine the frequency of undiagnosed abnormal glucose metabolism in patients with idiopathic sensory neuropathy. Patients were separated into two groups depending on presence or absence of painful symptoms, and an oral glucose tolerance test was performed. Of the 48 patients studied, those with painful symptoms had a higher frequency of abnormal glucose metabolism than literature-based controls, whereas patients without painful symptoms showed no difference. Comparison of patients with and without painful symptoms had a P-value of 0.02. The results indicate the need to consider undiagnosed abnormal glucose metabolism in patients with idiopathic sensory neuropathy. © 2001 John Wiley & Sons, Inc. Muscle Nerve 24: 1229–1231, 2001
