Abstract:Objective To study the physiological characteristics of peripheral neuropathy of impaired glucose regulation (IGR), and to analyze the influencing factors of neuropathy in IGR patients. Methods Fifty four IGR patients treated from August 2016 to August 2018 in our hospital were selected as research group. 50 healthy check-ups were selected as control group. The peripheral nerve function of the two groups of subjects was evaluated by nerve electrophysiological test. Nerve conduction detections (central nerve, ulnar nerve, tibia nerve, and total peroneal nerve) were used to evaluate large fiber conduction function, and small fiber function was evaluated by skin sympathetic reaction (SSR); the clinical biochemical indexes of fasting blood glucose (FBG), 2 h postprandial plasma glucose (2 hPG), glycosylated hemoglobin (HbA1c), cholesterol (TC) and triacylglycerol (TG) as well as blood uric acid (UA), Homocysteine (Hcy), body mass index (BMI) were observed. The Logistic regression equation was used to analyze its influence factors. Results The SCV of tibial nerve and sural nerve in the study group was lower than that in the control group (P?0.05). The amplitude of SSR in the study group was lower than that in the control group (P?0.05). The levels of FBG, 2 hPG, HbAlc, TC, LDL-C, BMI, UA and Hcy in the study group were higher than those in the control group (P?0.05). Multi-factor Logistic regression analysis showed that the factors affecting peripheral neuropathy in IGR patients were TG [OlR=8.529, (95% CI: 1.634, 43.372), LDL-C [OlR?=?3.273, (95% CI: 1.202, 8.927)], BMI [OlR?=?1.385, (95% CI: 1.122, 1.708)], UA [OlR?=?9.265, (95% CI: 1.896, 9.437)] and Hcy [OlR?=?11.336, (95% CI: 1.928, 16.774)]. Conclusions Peripheral neuropathy in IGR patients is caused by sensory neuromyopathy in large fibers and small fibers. The causes of neuropathy in IGR patients may be related to metabolic syndrome caused by disorders of BMI, TC, UA, and Hcy.
