Filter by:The difference between active treatment and placebo in a clinical trial of an analgesic appears to depend on a variety of factors other than the actual efficacy of the drug itself, including various aspects of study design and conduct. One potential such factor is how information about the study is presented to research staff and patients. The purpose of this study is to examine the impact of different presentations of information on the difference between pregabalin and placebo observed in a clinical trial in patients with painful diabetic neuropathy.
Anecdotal reports and scientific literature suggest that the risk of recurrence of diabetic foot ulcers can be minimized by nerve decompression procedures at anatomic sites of nerve pinching and entrapment. Historical risk of 25% annually has been reported to decrease by >80% to under 5% yearly. Since an open wound precedes the large majority (85%) of amputations in diabetes, avoidance of ulcer recurrences is important. This study tests the current academic opinion that nerve decompression will not decrease ulcer recurrence risk. Null hypothesis: nerve decompression will not decrease diabetic foot ulcer recurrence risk.
The purpose of this study is to evaluate the efficacy and safety of inotersen given for 65 weeks in participants with Familial Amyloid Polyneuropathy (FAP).
Background: The pathogenetic factors underlying development of diabetic polyneuropathy (DP) remain unclear. Reduced neurotrophic stimulation has been proposed as a possible mechanism. The neurotrophic factors IGF I and II, sCD-163, NGF, VEGF and BDNF are essential for development and regeneration of the nervous system. In earlier studies reduced concentrations of IGF-I and II in blood and reduced concentrations of NGF and BDNF in muscle and skin biopsies have been found in patients with DP. Purpose: Our purpose is to determine the concentration and biological activity of Insulin-like Growth Factor I and II (IGF-I and II), soluble Cluster of Differentiation 163 (sCD-163), Nerve Growth Factor (NGF), Vascular Endothelial Growth Factor (VEGF) and Brain-derived Neurotropic Factor (BDNF) in cerebrospinal fluid and in blood in patients with diabetes and/or nerve disease (especially diabetic polyneuropathy) as well as in healthy control subjects. We will furthermore relate the findings to peripheral nerve function. In addition the composition of the cerebrospinal fluid will be analyzed using mass spectrometry. Hypothesis: We hypothesize that DP develops due to reduced concentration and biological activity of neurotrophic factors. We expect the concentration of IGF-I and II, VEGF, NGF and BDNF to be reduced in cerebrospinal fluid in patients with DP compared to diabetic patients without damage to the nervous system and healthy control subjects. Methods: Study subjects consists of patients from Department of Neurology and Department of Department of Clinical Medicine (Endocrinology and Diabetes) Aarhus University Hospital, Denmark, who are having a lumbar puncture performed.
This study is comparing the efficacy and tolerability of Qutenza with that of pregabalin in patients suffering from peripheral neuropathic pain. Treatment allocation will be to one of these treatments and the duration of the study will be about 10 weeks (assuming that from screening to treatment allocation takes 2 weeks). Participants will be asked to complete questionnaires about various aspects relating to their condition throughout the study. This study will include subjects suffering from Postherpetic Neuralgia, Peripheral Nerve Injury or Non Diabetic peripheral polyneuropathy.
An International, multicenter, epidemiological observational study investigating the prevalence of Transthyretin-Related Familial Amyloidotic Polyneuropathy (TTR-FAP) in participants with small fiber polyneuropathy of no obvious etiology.
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.
This study is an online (web-based) or paper-based survey for patients with transthyretin familial amyloidosis polyneuropathy (TTR-FAP) and caregivers. The results will be used to describe the emotional, physical, and financial impact of having TTR-FAP or caring for someone who has the disease.
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.
