Classification of Abnormal Glucose Metabolism Based on the 2-Hour Oral Glucose Tolerance Test, Which Consists of Fasting Blood Glucose Level and Blood Glucose Level Measured 2 Hours after a 75-g Oral Glucose Load4
Diagnosis Fasting Glucose (mg/dL) 2-Hour Post Load Glucose (mg/dL) Normal glucose metabolism <110 and <140 Impaired fasting glucose 110–125 and <140 Impaired glucose tolerance <126 and 140–199 Diabetes mellitus ≥126 or ≥200 - Table 2.
Age-Adjusted Prevalence of Neuropathy in Patients with Altered Glucose Metabolism Compared with That of Control Subjects5
Normal Glucose Metabolism 3.9% Impaired Glucose Tolerance 11.2% Diabetes Mellitus 25.8% - Table 3.
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).
