Diabetic peripheral neuropathy (DPN), a common and troublesome complication in patients with type 2 diabetes mellitus (T2DM), contributes to a higher risk of diabetic foot ulcer and lower limb amputation. These situations can negatively impact the quality of life of affected individuals. Despite its high prevalence and clinical importance, most diabetes mellitus patients not only do not recognize the presence of diabetic neuropathy, but also do not report their symptoms to physicians or other health care providers. Therefore, DPN is usually under diagnosed and undertreated. For early detection and appropriate intervention for DPN, a careful history, physical with neurologic examination, and prompt treatment are needed in T2DM patients. 相似文献

AimsThe aim was to see the frequency of CAN in type 2 diabetes mellitus patients with peripheral neuropathy, and its association with peripheral nerve conduction abnormalities.MethodsA cross-sectional study at BIRDEM was conducted in 62 patients with type 2 diabetes mellitus having electrophysiologically diagnosed peripheral neuropathy. CAN was detected by four clinical tests - heart rate response to deep breathing and valsalva maneuver, blood pressure response to standing and sustained handgrip.ResultThe study showed that all patients had CAN – 14.52% had early, 26.67% had definitive and 59.68% had severe CAN. Patients with severe CAN had significantly reduced nerve conduction velocity and amplitude of peripheral nerves (sural 4.36 ± 12.77 vs 9.65 ± 17.77 m/s, p = 0.009; 2.23 ± 1.89 vs 3.01 ± 2.76 mV, p = 0.001; peroneal 7 ± 4.23 vs 8.53 ± 5.99 mV, p = 0.047; tibial 0.008 ± 0.03 vs 0.026 ± 0.05 mV, p = 0.009) and higher serum triglyceride levels (221.17 ± 120.61 vs 197.76 ± 68.43 mg/dl, p = 0.033).ConclusionDiabetic patients with peripheral neuropathy have CAN, the severity of which increases with worsening neuropathy. 相似文献

ObjectiveBurning mouth syndrome (BMS) has been attributed secondarily to diabetes, poor glycemic control, and diabetic neuropathy. The prevalence and predictor factors of BMS were compared in type 1 diabetes mellitus (T1DM) and nondiabetic subjects.Study designAn assessment of 371 adult T1DM subjects and 261 control subjects participating in a cross-sectional epidemiological study of oral health complications of diabetes was performed. Subjects were participants of the Pittsburgh Epidemiology of Diabetes Complications study. Prevalence of BMS was determined by response to the following questions: “Do you now or in the last month had any persistent uncomfortable sensations in your mouth or tongue? If yes, would you describe the feeling as tingling, burning, sore, numb, or other?”ResultsBurning mouth syndrome symptoms were reported by 28 T1DM and control subjects (4.6%). Eleven had oral pathologies that might explain the BMS, including atrophy of the tongue papillae, fissured tongue, denture stomatitis, and candidiasis. The prevalence of BMS within the two groups with no pathologies was similar; 12/371 (3.2%) vs. 5/233 (2.1%). Multivariate analyses of the 12 T1DM subjects with BMS found significant associations for female gender (P=.042) and a diagnosis of diabetic peripheral neuropathy (P=.024).ConclusionsIn this T1DM population, BMS or related discomforts occurred slightly more frequently than in the control group. Symptomatic T1DM subjects were more likely to be female who had also developed peripheral neuropathy. These findings and other similarities between BMS and diabetic peripheral neuropathy suggest that a neuropathic process may be an underlying source of BMS in some patients who have no apparent oral abnormality. 相似文献

AimsTo examine for differences in circulating progenitor cells (CPCs) and endothelial progenitor cells (EPCs) in patients with and without diabetic peripheral neuropathy (DPN).MethodsA total of 105 participants were included: 50 patients with type 2 diabetes (T2DM) and DPN, 30 patients with T2DM without DPN and 25 healthy individuals. CPCs and 6 different EPCs phenotypes were assessed with flow cytometry. We also measured plasma levels of vascular endothelial growth factor (VEGF), stromal cell-derived factor 1 (SDF-1), vascular cell adhesion protein-1 (VCAM-1), intracellular adhesion molecule-1 (ICAM) and tumor necrosis factor a (TNFa).ResultsNo difference was observed in the number of CPCs among the 3 groups. Patients with DPN had higher numbers of all 6 EPCs phenotypes when compared with patients without DPN and higher number of 5 EPCs phenotypes when compared with healthy individuals. Plasma VEFG, VCAM-1, ICAM-1 and TNFa levels did not differ among the 3 groups. Patients with DPN had lower SDF-1 levels in comparison with healthy individuals.ConclusionCirculating EPCs are increased while SDF-1 levels are decreased in the presence of DPN. Our findings suggest that DPN may be associated with impaired trafficking of EPCs and impaired EPCs homing to the injured endothelium. 相似文献

The aim of the study was to evaluate differences in the relationship between peripheral diabetic neuropathy and microvascular reactivity in type 1 and type 2 diabetic patients. Twenty-eight type 1 and 37 type 2 diabetic patients were included in the study. Control groups consisted of 18 and 25, age and body mass index matched healthy persons. The presence of peripheral neuropathy was estimated by vibration perception threshold higher than 20 V evaluated by biothesiometry. Microvascular reactivity was examined by laser doppler fluxmetry using postocclusive reactive hyperemia and thermal hyperemia. The following variables of vascular reactivity were examined: peak flow after occlusion as a difference between maximal and basal perfusion (PORH (max)), mean velocity increase during postocclusive hyperemia (PORH (max)/t (1)), peak flow during thermal hyperemia (TH (max)) and the mean velocity increase in the perfusion during thermal hyperemia (TH (max)/t (2)). These parameters are expressed in perfusion units (PU) or in perfusion units per second (PU . s (-1)). The microvascular reactivity in type 1 diabetic patients without evidence of peripheral neuropathy was comparable with that in healthy persons and it was significantly higher than in type 1 diabetic patients with peripheral neuropathy in all tested parameters (PORH (max): 64 [40; 81] PU vs. 24 [17; 40] PU, p < 0.001, PORH (max)/t (1): 5.41 [2.69; 8.18] PU/s vs. 1.21 [0.69; 2.5] PU/s, p < 0.001, TH (max): 105 [77; 156] PU vs. 56 [46; 85] PU, p < 0.001 and TH (max)/t (2): 2.48 [1.67; 3.33] PU/s vs. 0.87 [0.73; 1.06] PU/s, p < 0.001). On the contrary, no difference in the microvascular reactivity parameters was found between type 2 diabetic patients with and without neuropathy (PORH (max): 48 [30; 60] PU vs. 49 [36; 57] PU, NS, PORH (max)/t (1): 3.46 [2.15; 5.19] PU/s vs. 3.29 [2.45; 4.8] PU/s, NS, TH (max): 95 [78; 156] PU vs. 97 [73; 127] PU, NS and TH (max)/t (2): 1.45 [0.95; 2.84] PU/s vs. 1.37 [1.12; 1.95] PU/s, NS). In both these groups microvascular reactivity was comparable with that estimated in the age and BMI matched healthy persons. An inverse relationship was observed between microvascular reactivity and vibratory perception threshold in type 1 diabetic patients, but it was not true in type 2 diabetic patients. We suppose that the pathogenesis of neuropathy and impaired microvascular reactivity may be differently influenced by metabolic factors in type 1 and type 2 diabetic patients. 相似文献

Objective Patients with type 2 diabetes mellitus are at greater risk of bone fractures than nondiabetics. However, the risk factors for fractures in patients with diabetes have not been fully evaluated. This study was designed to evaluate the relative frequency of fractures at different sites and the diabetes‐associated factors that affect nontraumatic bone fracture in patients with type 2 diabetes. Patients and design This retrospective case–control study recruited 144 patients with type 2 diabetes, who presented with nontraumatic fractures between March 2004 and March 2009 and 150 age‐, gender‐, body mass index (BMI)‐ and duration of diabetes‐matched control subjects. Nontraumatic fractures were confirmed using patients’ medical records and radiological findings. All subjects were examined for their diabetes status and associated factors for fracture, including bone mineral density (BMD). Results Of 150 reported bone fractures, the hip was the most frequent fracture site (32·7%), followed by the upper extremity (19·3%). Nontraumatic fractures were associated with diabetic retinopathy, diabetic peripheral neuropathy, stroke history, previous fracture and insulin treatment (P < 0·05). In multivariate analyses, independently associated factors for bone fracture were diabetic peripheral neuropathy [odds ratio (OR) = 37·3, 95% confidence interval (CI) = 1·46–652·57] and previous fracture (OR = 9·54, 95% CI = 1·18–77·37; P < 0·05). Conclusions The hip was the most frequent site of nontraumatic fracture, and diabetic peripheral neuropathy was significantly associated with an increased risk of nontraumatic fractures in patients with type 2 diabetes. 相似文献

OBJECTIVE: The objective of this study was to evaluate the sensitivity and specificity of a new indicator test (Neuropad) for the diagnosis of peripheral neuropathy in type 2 diabetes patients as compared with clinical examination and nerve conduction study (NCS). PATIENTS AND METHODS: This study included 120 type 2 diabetes patients (58 men) with a mean age of 67.3 +/- 5.9 years and a mean diabetes duration of 13.1 +/- 3.2 years. Diabetic neuropathy was diagnosed through the Neuropathy Disability Score. An NCS was performed on radial, ulnar, sural, and common and deep peroneal nerves. Patients were also examined with the new indicator test. The "time to complete color change of the test" from blue to pink was recorded. The test was considered abnormal in patients who exhibited a time to complete color change of the test exceeding 600 s in at least one foot. RESULTS: Neuropathy was diagnosed by clinical examination in 83 (69.2%) patients. The sensitivity of the indicator test for clinical neuropathy was 95.2%, and its specificity was 67.6%. The sensitivity of NCS for clinical neuropathy was 94%, and its specificity was 62.1%. The sensitivity of the indicator test for abnormal NCS was 97.8%, and its specificity was 96.4%. CONCLUSIONS: The new indicator test has a very high sensitivity not only for the diagnosis of clinical neuropathy but also for the diagnosis of neurophysiological neuropathy. Specificity is moderately high for the diagnosis of clinical neuropathy, while it is particularly high for the diagnosis of neurophysiological neuropathy. The indicator test has a validity comparable to that of NCS for the diagnosis of diabetic neuropathy. Finally, the time to complete color change of the test is associated with the severity of nerve conduction impairment. 相似文献

Aim
To explore the relationship between plasma total homocysteine concentration and diabetic neuropathy in Chinese patients with type 2 diabetes.Methods
Chinese patients with type 2 diabetes (n = 249) were enrolled in a cross-sectional hospital based study. Diabetic neuropathy status was documented by presence of clinical signs and confirmed by electromyography. Plasma total homocysteine concentration was measured using fluorescence polarization immunoassay. Traditional risk factors for diabetic neuropathy were obtained from fasting blood samples and interviewer-questionnaire.Results
Plasma total homocysteine levels were higher in subjects with diabetic neuropathy than without (12.8 (9.2-14.8) μmol/l vs. 8.0 (7.7-9.1) μmol/l, p = 0.005). The association of homocysteine with diabetic neuropathy was independent of major traditional risk factors for diabetic neuropathy (duration of diabetes, HbA1c) and determinants of higher homocysteine concentration (age, gender, serum folate and vitamin B12, renal status, and Biguanide use) (OR: 1.12 (1.00-1.25), p = 0.042). Furthermore, per increase of 4.0 μmol/l plasma homocysteine was related to neuropathy, after controlling for per unit increase of other factors (OR: 1.17 (0.94-1.33), p = 0.045).Conclusion
Plasma total homocysteine concentration was independently associated with occurrence of diabetic neuropathy in Chinese people. Future prospective studies are warranted to clarify the relationship. 相似文献15.

Diabetic neuropathy is probably the most frequent of the chronic complications of diabetes, and is usually found in association with diabetic retinopathy and/or nephropathy. We report seven patients with long-standing insulin-dependent diabetes mellitus in whom symptomatic peripheral neuropathy was the first and only documented complication. The diagnosis of peripheral symmetrical neuropathy was based on the presence of symptoms and abnormal physical findings, confirmed with abnormal electrophysiological and/or vibratory and thermal threshold measurements. Diabetic retinopathy and nephropathy were absent. We conclude that in some type 1 insulin-dependent diabetic patients, similar to what has been reported in type 2 non-insulin-dependent diabetes, peripheral neuropathy may be the first chronic complication to become manifest. This observation provides additional evidence to suggest that each of the diabetic complications may have a different pathogenic mechanism. 相似文献

AIMS: The aim of the present study was to assess the performance of a new indicator test (NIT), based on the measurement of sweat production after exposure to dermal foot perspiration, in the diagnosis of both peripheral sensorimotor polyneuropathy (PSN) and autonomic neuropathy in patients with diabetes. METHODS: One hundred and seventeen diabetic patients were examined. PSN was assessed using the neuropathy symptoms score, the neuropathy disability score and the vibration perception threshold. Cardiac autonomic neuropathy (CAN) was assessed using the battery of the four classical standardized tests proposed by Ewing et al., Diabetes Care 1985; 8: 491-498. Sudomotor dysfunction was assessed using the NIT. Results: Fifty patients (42.7%) had PSN and 44 patients (37.6%) had CAN. Of the 50 patients with PSN, 43 had a positive NIT (sensitivity 86%) and, out of the 67 patients without PSN, a negative NIT was obtained in 45 patients (specificity 67%). The positive and the negative predictive value of the NIT in detecting PSN were 66.2 and 86.5%, respectively. The sensitivity and specificity of NIT in detecting CAN was 59.1 and 46.5%, respectively. In the case of severe CAN, the sensitivity was increased to 80.9% and the specificity to 50%. CONCLUSIONS: The NIT has good sensitivity and negative predictive value for diagnosis of PSN and can be used as a screening method for detection of this complication in patients with diabetes. In addition, the test has a low sensitivity for detection of autonomic neuropathy in patients with milder forms of CAN. 相似文献
