Filter by:This study is a diagnostic accuracy study that aims to evaluate the role of DTI in evaluation of DPN in comparison to clinical scores and nerve conduction studies (NCS). The study included 30 patients with diabetes mellitus complaining of neuropathy symptoms and 15 healthy volunteers. All subjects underwent evaluation using 1.5T DTI of median nerves and NCS. Patients underwent clinical evaluation using Neuropathy Deficit Score (NDS), Neuropathy Impairment Score in the Lower Limbs (NIS-LL) and Diabetic Neuropathy Examination (DNE) score. The values of these tests were compared and correlated and diagnostic accuracy tests were performed together with identification of cut-off score for abnormal diffusion tensor imaging parameters in diabetic neuropathy
This study evaluated the spatio-temporal gait parameters and gait symmetry in individuals with lower extremity burn injury due to diabetic polyneuropathy. Study group consisted of 14 subjects with unilateral lower extremity burn injuries due to diabetic polyneuropathy and control group consisted of 14 subjects with only diabetic polyneuropathy.
Through the multinational pooled dataset approach, this trial will aim to derive and validate specific in vivo Corneal Confocal Microscopy (CCM) parameter thresholds for the identification of diabetic polyneuropathy, and - more importantly - the identification of individuals at future risk. Results of the study will permit application in clinical practice and intervention trials for diabetic polyneuropathy (DPN) risk stratification. The primary goal of the study is to re-examine individuals with type 1 and type 2 diabetes with and without neuropathy, who had CCM performed in the past as a part of their neurological examination, to assess concurrent and predictive validity of different CCM parameters in individuals . These subjects will be invited to the study to be re-examined by CCM along with other neurological tests (physical exam, nerve conduction studies, quantitative sensory testing, blood test and in some centres also skin biopsy) during the single study visit. Additionally CCM data will be analyzed both manually and by recently developed automated analytical software to evaluate accuracy of the automated method. Evaluation of automated image analysis will influence likelihood of successful knowledge translation of this surrogate biomarker for DPN into clinical practice - in which the procedure could be harmonized with annual retinal examinations - and into intervention trials. Secondary aim of the study is to determine the factors associated with CCM parameters and their longitudinal change and collect bio-samples for future research in this field.
Aims: To evaluate the effect of ezetimibe/simvastatin and rosuvastatin on oxidative stress and mitochondrial function in patients with DPN. Methods: We performed a randomized, double-blinded, placebo-controlled phase II clinical trial in adult patients with type 2 Diabetes Mellitus (T2DM) who had Diabetic Polyneuropathy (DPN) evaluated by composite scores and nerve conduction studies (NCS), HBA1C <12% (108 mmol/mol), previous exclusion of other neuropathies. Ninety-eight persons with T2DM were allocated 1:1:1 to either placebo, ezetimibe/simvastatin 10/20 mg or rosuvastatin 20 mg for 16 weeks, and healthy controls (not randomized) were included for comparisons. Primary outcomes were lipid peroxidation (LPO), nitric oxide (NO), and total antioxidant capacity (TAC); secondary were clinical, NCS and metabolic parameters. Results were expressed as mean ± standard deviation (SD) or standard error of the mean (SEM), frequencies and percentages. Non-parametric analysis was used.
The purpose of the study is to determine whether phyllanthus niruri and sida cordifolia are effective in treatment of diabetic polyneuropathy compared to placebo. Also two different administration forms (extract capsules and crude herbs) are used to find out whether there are differences in efficiency and compliance.
This project aims to develop high field MR techniques to detect nerve lesions in diabetic patients. The MRI findings will be compared to results from conventional evaluations and nerve conduction studies to determine the validity as part of a clinical practice.
To evaluate the impact of oral rosuvastatin in diabetic polyneuropathy, and the role of lipid peroxidation and nerve growth factor.
The purpose of this study is to determine whether Magnetic Marker Monitoring is an appropriate opportunity to diagnose and to quantify a suspicious gastroparesis in subjects with diabetic polyneuropathy.
The purpose of this study is to find out the impact of improving diabetes control through weight reduction and lifestyle changes on a common diabetes complication called peripheral neuropathy.
The prevalence of diabetes mellitus (DM) in industrialized countries is estimated to be about 7.3% and its incidence has been growing in recent years. The prevalence of diabetic neuropathy in the diabetic patient population is up to 50%. When limb surgery is necessary, it is reasonable to assume that diabetic patients will benefit from a peripheral regional anesthesia because of the severe comorbidities associated with DM. On the other hand, the use of regional anesthesia (RA) has generally not been recommended in patients with preexisting neuropathies mainly because of medical liability issues, as worsening neuropathy could be attributed to nerve damage caused by the regional anesthetic. The current state of the art of peripheral regional anesthesia for the identification of correct placement of an injection needle suitably close to the target nerve is to elicit a motor response by current injection through the needle. Constant reduction of the current as the nerve is approached ensures close proximity so that an effective nerve block is obtained when the local anesthetic is delivered through the needle, and absence of a motor response at 0.3 mA is generally accepted as a safety marker to avoid harmful intraneural injection. An important deficit in our understanding is whether diabetic neuropathy influences the stimulation parameters for peripheral nerve stimulation (PNS), possibly decreasing safety. The currently proposed research is guided by the hypothesis that nerves in patients with DM are more resistant to stimulation and the current thresholds for PNS have to be set much higher to prevent injections from occurring within the epineurium. The investigators will examine the effect of DM on nerve excitability in a blinded, prospective, observational case control trial. Accordingly, the investigators have defined following aims: Specific Aim 1: To characterize the required stimulation current in patients with and without diabetes mellitus. Specific Aim 2: Follow-up to examine if the rate of adverse neurologic events is higher in diabetic patients. Specific Aim 3: Guided by the results, formulate recommendations for the performance of regional anesthesia in patients with a history of DM. These experiments will provide better understanding of the needle-current-nerve relationship during peripheral nerve stimulation. Findings from this study will have a major impact on patient safety, especially in the subgroup with preexisting neuropathy, undergoing regional anesthesia.
