定量感觉检查在糖尿病周围神经病变诊断中的应用

目的 了解定量感觉检查在糖尿病周围神经病变诊断方面的应用。方法 使用温度觉分析仪及振动觉分析仪,用“极限”（limits)法测定22例正常人及45例糖尿病患者肢体四个部位的温度觉、振动觉阈值,并同时检查感觉传导速度。结果 糖尿病患者的温度觉阈值、振动觉阈值显著地高于年龄匹配的正常人;糖尿病患者温度觉阈值异常率显著地大于振动觉阈值,提示小神经纤维受损比大神经纤维更常见;定量温度觉检查对糖尿病周围神经病变的诊断敏感性高于定量振动觉检查及感觉神经传导速度;糖尿病患者温度觉阈值、振动觉阈值与血糖无显著相关性。结论 定量感觉检查（特别是定量温度觉检查）对糖尿病神经病变的诊断是一种敏感的方法。

定量感觉检查对早期糖尿病周围神经病变患者诊断的价值

根据有或无DPN症状将290名T2DM患者分为有症状组和无症状组,每个患者分别测定QST包括冷感觉（CPT）和热感觉（WPT）及振动觉（QVT）阈值,同时测定双侧正中、尺、胫神经运动支及正中、腓肠神经感觉支的NCV,分析QST与NCV异常率之间的差异和QST阈值与NCV之间的相关性。结果：有症状组T2DM患者CPT阈值明显降低、WPT及QVT阈值明显升高（P值〈0.05）。有症状组和无症状组T2DM患者中QST各项阈值的异常率均明显高于NCV各项的异常率（,P值〈0.05）。T2DM患者QST各项阈值和NCV之间存在一定的相关性。结论：T2DM患者未出现DPN的症状时,已存在QST阈值的异常,并随糖尿病病程的发展逐渐加剧;与NCV检测相比,QST异常能更早发生。

目的 通过比较无糖尿病的人群和2型糖尿病患者的纯音听阈值、振动觉阈值(VPT),了解2型糖尿病患者周围神经病变(DPN)与耳聋的关系.方法 测定173例研究对象的VPT及纯音听阈值,2型糖尿病患者同时测定感觉神经传导速度(SCV)和运动神经传导速度(MCV),将其分为对照组35例,无糖尿病神经病变组74例,糖尿病伴神经病变组64例.比较3组的基本情况、感音神经性耳聋(SNHL)发生率、纯音听阈值和VPT值,分析听阈值和神经传导速度的关系.结果 伴神经病变的糖尿病组SNHL发生率为29.69%,明显高于无糖尿病神经病变组(17.57%)和对照组(17.14%),且3组的年龄、糖尿病病程、HbA1c、糖化血清蛋白(GA)、空腹血糖、餐后2 h血糖、VPT和听阈值之间有显著性差异(均P＜0.05).不同VPT亚组的听阈值之间也存在明显差异(均P＜0.05).正中神经传导速度与1.00、2.00、4.00、8.00kHz听阈值呈明显负相关,logistic回归分析显示,年龄(回归系数=0.088,P＜0.01)是SNHL的独立危险因素,正中神经MCV(回归系数=-0.135,P=0.046)是影响SNHL的重要因素.结论 糖尿病患者易影响中高频听力,DPN患者常同时合并听力受损,年龄、正中神经MCV是影响SNHL的主要危险因素.

Abstract：

Objective In order to investigate the relationship between hearing loss and diabetic peripheral neuropathy( DPN ) via comparing the pure tone thresholds and vibration perception threshold(VPT) in type 2 diabetic patients and control person without diabetes. Methods 173 subjects including 138 type 2 diabetic patients(DM)and 35 non-diabetes controls were examined for VPT and hearing threshold. Nerve conducting velocity ( NCV )including sensory nerve conducting velocity( SCV )and motorial nerve conducting velocity( MCV )of diabetic patients were determined. The participants were divided into three groups: control group (n = 35 ), DM group without peripheral neuropathy( non-PN group, n = 74 ), and DM group complicated with peripheral neuropathy (PN group,n = 64 ). The clinical characteristics, biochemical parameters , the incidence of sensorineural hearing loss ( SNHL),pure tone threshold, and VPT were compared among three groups. At last, the relationship between hearing thresholds and NCV were analyzed. Results The incidence of hearing impairment of sensorineural type was 29.69% in PN group, which was significantly higher than that of non-PN group( 17.57% )and control group( 17. 14% ). There was significant differences in age, duration of diabetes, glycolated hemoglobin (HbA1c), glycolated serum albumin ( GA), Fasting blood glucose( FPG), 2h postprandial blood glucose( PPG), VPT, and hearing threshold among the three groups( all P＜0. 05 ). The value of hearing threshold increased significantly( all P＜0. 05 ) in 3 VPT subgroups with VPT≤ 15 V, VPT 16-25 V, and VPT ＞25 V. The Spearman correlation analysis showed median NCV was negatively correlated with hearing threshold on 1.00, 2.00, 4. 00, and 8. 00 kHz ( All P ＜ 0. 05 ). The logistic regression analysis indicated that the age( regression coefficient =0. 088, P＜0. 01 ) was the independent risk factor of SNHL, median nerve MCV ( regression coefficient = -0. 135, P = 0. 046 ) was the important influencing factor of SNHL. Conclusion Diabetic patients are more likely to suffer from impaired middle-frequency and high-frequency hearing, DPN in patients is often complicated with hearing impairment. Age and median nerve MCV were major risk factors of SNHL in diabetic patients.     

Prevalence and risk factors for diabetic peripheral neuropathy,neuropathic pain and foot ulceration in the Arabian Gulf region

Aims/IntroductionThis study determined the prevalence and risk factors for diabetic peripheral neuropathy (DPN), painful DPN and diabetic foot ulceration (DFU) in patients with type 2 diabetes in secondary healthcare in Qatar, Kuwait and the Kingdom of Saudi Arabia.Materials and MethodsAdults aged 18–85 years with type 2 diabetes were randomly enrolled from secondary healthcare, and underwent clinical and metabolic assessment. DPN was evaluated using vibration perception threshold and neuropathic symptoms and painful Diabetic Peripheral Neuropathy was evaluated using the Douleur Neuropathique 4 questionnaire.ResultsA total of 3,021 individuals were recruited between June 2017 and May 2019. The prevalence of DPN was 33.3%, of whom 52.2% were at risk of DFU and 53.6% were undiagnosed. The prevalence of painful DPN was 43.3%, of whom 54.3% were undiagnosed. DFU was present in 2.9%. The adjusted odds ratios for DPN and painful DPN were higher with increasing diabetes duration, obesity, poor glycemic control and hyperlipidemia, and lower with greater physical activity. The adjusted odds ratio for DFU was higher with the presence of DPN, severe loss of vibration perception, hypertension and vitamin D deficiency.ConclusionsThis is the largest study to date from the Middle East showing a high prevalence of undiagnosed DPN, painful DPN and those at risk of DFU in patients with type 2 diabetes, and identifies their respective risk factors.     

Ganglioside treatment in diabetic peripheral neuropathy: A multicenter trial

Summary Ganglioside treatment was evaluated with a multicenter, randomized, double-blind, controlled, cross-overvs placebo trial in 140 insulin-treated diabetic subjects with peripheral neuropathy. The patients entered the study when they showed an impairment in at least two of the electroneurographic parameters, and were assigned to two protocols according to the presence and severity of their neurological symptoms. Ninety-seven diabetic subjects with no or mild symptoms were assigned to protocol I, whereas 43 symptomatic patients were assigned to protocol II. The treatment periods lasted 6 weeks with an intermediate washout period of 4 weeks. The treatment consisted in the daily i.m. administration of 20 mg gangliosides or of placebo. Electroneurographic parameters were recorded at the beginning and at the end of each treatment period, whereas clinical and metabolic data (mean daily plasma glucose, glycosuria and glycosylated hemoglobin) were evaluated every three weeks in protocol I and every two weeks in protocol II. No change in the metabolic parameters was observed throughout the trial period. However, the treatment induced a statistically significant improvement of paresthesias (protocol II) and of some electrophysiological parameters; in particular, ganglioside treatment improved MCV of peroneal nerve (p<0.03) in patients of protocol I, MCV of ulnar nerve (p<0.002) and SCV of median nerve (p<0.06) in patients of protocol II. Furthermore, 22 subjects of protocol II showed a ‘drug preference’ while 10 preferred placebo and 9 had no preference. In conclusion, ganglioside treatment seems to have a positive effect on diabetic peripheral neuropathy, improving both some symptoms and some electrophysiological parameters.
