Active clinical trials for "Diabetic Neuropathies"

In this study, a randomized, double-blind, placebo parallel-controlled design was used to evaluate the effectiveness and safety of YJ001 spray applied to local skin in patients with diabetic peripheral neuropathic pain, and to explore the best effective dose.

International Diabetes Federation estimates that there are now 415 million adults aged 20-79 with diabetes mellitus worldwide. By 2040 this will rise to 640 million. Although diabetes mellitus is highly prevalent in our environment and one of the most important challenges of modern medicine, only a handful of studies have examined the neuromuscular function in diabetic patients. The shortage of publications in this area is still more surprising if we consider that the neuromuscular blockers are one of the pillars in the administration of general anesthesia. Neuromuscular blockers during surgery are used in tracheal intubation and to improve surgical conditions.

The overall objective of this project is to describe the prevalence of and risk factors to diabetic neuropathy in a representative cohort of diabetes patients and to investigate pathophysiological conditions in those patients with neuropathy. This project will yield substantial new knowledge about the prevalence of diabetic neuropathy in type 1 and type 2 DM persons, new risk factors to neuropathy and the association to other diabetic complications. Findings related to the study may facilitate new treatment regimens prompting a better neuropathy treatment with reduced incidence of diabetic complications. First patients at SDCC will be screened for diabetic neuropathy (Study 1.1) with an extended neuropathy screening program as an addition to the routine neuropathy screening at SDCC. 1000 patients with type 1 DM and 1000 patients with type 2 DM will be included. This screening study is a prerequisite for the further study of study participants in substudies investigating associations between diabetic neuropathy and diabetic complications as described below. Hypothesis: Several patients with diabetes have undiagnosed neuropathy and associated diabetic complications. We hypothesize that diabetic neuropathy is underdiagnosed at SDCC and can be diagnosed with targeted screening with new and traditional measuring techniques. In addition, several patients may have complications related to neuropathy, including foot complications, and dysregulation of glucose metabolism Aim: This study consists of a screening study (study 1.1) and two substudies (1.2 and 1.3 ). Study 1.1 is a cross-sectional study describing the prevalence of diabetic neuropathy based on questionnaire data and objective measures as described below and associated diabetic complications including foot complications. The primary aim is to explore the prevalence of diabatic neuropathy in patients with type 1 and type 2 DM at SDCC and secondarily to explore associations between diabetic neuropathy and complications, as described in the respective sections below. The substudy 1.2 is an observational single center cohort study with the aim of investigating associations between neuropathy diagnosed with new devices for measurement of neuropathy and foot complications in patients with type 1 and type 2 diabetes. The substudy 1.3 is an observational single center cohort study investigating the association between CAN and glycemic variability in patients with type 1 diabetes.

Significant differences in the expression of individual Growth Differentiation Factor 15 (GDF-15) proteins among Taiwanese harboring different mitochondrial genotypes are noted, and their blood serum levels also exhibited associations with diabetes. GDF-15 was originally discovered as an autocrine regulator of macrophage activation and shown to play important roles in fibrosis, malignancy, cardiovascular disease, glycemic control, and obesity. However, the relationship between GDF-15 and pre-diabetes and diabetes in Asian populations has yet to be fully investigated. Besides, any indirect associations between GDF-15 levels and diabetic complications remain unclear. The investigators aim to further investigate the role of GDF-15 levels in the initial diagnosis of diabetes, the monitoring of medication effectiveness and disease progression, and related complications such as diabetic nephropathy and neuropathy. The DNA isolated from the blood samples will be evaluated to determine individual mitochondria haplogroups, including variants located within the coding and control regions of the mitochondrial genome.

To detect small fiber neuropathy in patients with possible or established diabetic peripheral neuropathy (DPN) by skin biopsy and explore clinical characteristics and pathological features in Chinese patients with diabetes.

This project intends to use high-throughput sequencing, molecular biology and bioinformatics technology to clarify the role of target lncrnas in the inflammatory response of DPN, to explore the correlation between target lncrnas and DPN pathogenesis, and to clarify the feasibility of target lncrnas as a marker of DPN cycle.

The primary purpose of this study is to determine the degree of loss of epidermal nerve fibers near a foot wound in patients with diabetic foot ulcers. The secondary purpose will be to determine whether the degree of epidermal nerve fiber loss, the clinical examination, nerve conduction studies or the molecular profile correlates with appearance of lower extremity ulcers in patients with diabetes.

This study will evaluate the balance ability of DPN (diabetic peripheral neuropathy)patients, which will help us to understand the relationship between peripheral and central nervous system, in order to early diagnosis and prevent the fall in DPN patients.

Painful Diabetic peripheral Neuropathy Study of Chinese OutPatiEnt (PDN-SCOPE): a multi-center cross-sectional registry study of clinical characteristics and treatment survey of PDN in China

In the context of peripheral neuropathy, we will aim to elucidate correlates between sensory symptoms and: Sensory nerve dysfunction. Cutaneous small nerve fibre innervation density. Psychological co-morbidity. Circadian rhythm disturbance co-morbidity. Functionality and Quality of life. Patterns of human brain activity in a subset of patients that consent to participate in the FMRI (functional magnetic resonance imaging) component of PINS. 2. We will also collect blood samples in this phenotyped cohort of patients. These blood samples coupled with detailed phenotype data will investigate potential gene associations only in the development of painful neuropathy. 3. Knowledge gained from the study will be used to aid the further development of pain questionnaires, designed to detect patients with painful neuropathy. 4.Knowledge gained from the study will be invaluable in informing on-going investigations of painful peripheral neuropathy in animal models, both in our laboratory and others.
