The Incidence of Occult Diabetes and Impaired Glucose Tolerance in Patients Referred to Neuromuscular Clinics with a Diagnosis of ′Idiopathic′ Sensory Neuropathy
| Study | Incidence of Impaired Glucose Metabolism |
|---|---|
| Palade et al, 200010 | 10/75 (13%) |
| Singleton et al, 200111 | 48/107 (45%)* 13 DM and 35 IGT |
| Novella et al, 200112 | 24/48 (50%)† 11 DM and 13 IGT |
| Sumner et al, 200313 | 41/73 (56%) 15 DM and 26 IGT |
DM, diabetes mellitus; IGT, impaired glucose tolerance; GTT, oral glucose tolerance test.
* Includes 13 of 33 patients with abnormal GTT and normal fasting glucose, and 10 of 21 patients with abnormal GTT and normal glycosylated hemoglobin level.
† Of the 28 patients with painful neuropathy, 18 (65%) had abnormal glucose metabolism (8 of 28 DM and 10 of 28 IGT).
