15 Clinical Trials for Various Conditions
The main objective is to demonstrate the effects of early dopaminergic activation on the autonomic nervous system in subjects with newly diagnosed vs. established type 2 diabetes. The primary endpoint is the effect of Bromocriptine QR on changes in autonomic function measured by assessing sympathetic and parasympathetic function using conventional measures of autonomic function, including power spectral analysis of heart rate as well as peripheral autonomic function using sudorimetry and laser scanning of peripheral microvascular autonomic control.
The focus of this project is cardiovascular diabetic autonomic neuropathy (DAN). DAN affects the nerves that control heart rate and blood flow to the heart in people with diabetes. DAN may cause problems with the rhythm of the heartbeat or decrease blood flow to the heart. Three medications will be tested for their effectiveness in DAN.
The purpose of this study is to measure the prevalence and severity of cardiac autonomic neuropathy (CAN), diabetic autonomic neuropathy (DAN) which in non-diabetics is termed advanced nervous system (ANS) dysfunction, and autonomic dysfunction as well as the overall sympathovagal balance (SB) in the CEFH population of diabetic patients versus non-diabetic patients undergoing elective vitreoretinal surgery.
The purpose of this study is to assess the durability of effect of Droxidopa in treating symptoms of neurogenic orthostatic hypotension in patients with Primary Autonomic Failure (Pure Autonomic Failure, Multiple System Atrophy, Parkinson's Disease), Non-diabetic neuropathy, or Beta Hydroxylase deficiency.
People with diabetes can, over time develop nerve damage throughout the body with symptoms such as pain, tingling, or numbness (loss of feeling) in the hands, arms, feet and legs.
The purpose of this study is to determine the safety and effectiveness of TAK-583, once daily (QD), in the treatment of neuropathy caused by diabetes mellitus.
The purpose of the study is to determine whether the combination of the the three drugs gabapentin, duloxetine, and donepezil are effective in treating pain in people with diabetic neuropathy or patients with failed low back syndrome (chronic back pain).
Investigators with the goal of optimizing glycemic and blood pressure control saw type 1 diabetic patients weekly. A control group received 3-4 subcutaneous insulin injections per day; an intravenous insulin pulsed infusion group received, in addition, three one hour infusions in a pulsatile fashion over one eight hour period each week. Patients were followed for 12 months with periodic testing of renal function by repeated blood and urinary analyses; diabetes control by blood testing and diabetes impact measurement score; cardiac and autonomic function by echocardiography, 24 hour electrocardiographic testing; and visual changes with repeated fundus photography. The study hypothesis was that correction of respiratory quotient would correct the defect leading to microvascular complications of diabetes (Type 1).
Type 2 diabetes results in a host of neuromuscular, muscular, and autonomic system impairments that accelerate age-associated limitations in functional independence and the risk of falls. Diabetic peripheral neuropathy (DPN) contributes to functional declines in balance and mobility because of limitations metabolic abnormalities. The constellation of impairments accompanying type 2 diabetes diminishes muscle function and performance including strength and power. Loss of strength at higher speeds of movement (deficit in power) occurs in neural activation of muscles, changes in muscle properties, and through in older individuals with DPN compared to older controls. Consequently, this deficit in speed dependent muscle power production leads to limitations in rapidly responding to sudden loss of balance stability to prevent falling. The goal of this pilot research program is to determine the feasibility and effectiveness of a mechanism-based therapeutic intervention fro improving balance and mobility functions and preventing falls in older adults with DPN. The investigators pan to use the results from this pilot study to design and implement a larger randomized control trial.
This is a case-controlled study using an innovative, non-invasive, FDA approved technology to measure the autonomic nervous system. Detection of unsuspected DPN or ANS dysfunction may allow physicians to re-assess current treatment and develop new dietary or pharmacological strategies. This also is an immense public health concern since there are currently 18 million diabetics in the United States and 220 million worldwide.
Type 2 diabetes (DM2) affects nearly 20 million people in the United States while impaired glucose regulation (IGR), which includes impaired glucose tolerance (IGT), impaired fasting glucose (IFG), and early diabetes affects a considerably larger but unknown population group. At the current time there is no effective therapy to completely prevent, or reverse neuropathy associated with IGR and this represents a considerable challenge in rehabilitation. There is a particularly strong incentive to prevent IGT and related complications from advancing to DM2. IGR is a growing problem among all older adults and its strong association with many functional limitations, particularly mobility limitations, is not always recognized, even though diabetes-related disability occurs in up to 2/3 of older adults with diabetes and is associated with dependency, poor quality of life, and increased acute and long-term care utilization. Autonomic dysfunction is a significant problem in subjects with IGT. The Preliminary Data shows that over 90% of subjects with IGT have an abnormal score on questionnaires about autonomic symptoms such as lightheadedness, dry mouth or dry eyes, pale or blue feet, feet that are colder than the rest of the body, decreased sweating in the feet or increased sweating in the hands, nausea or bloating after eating, persistent diarrhea or constipation, or leaking of urine. In addition, patients with IGR have impaired balance control. These factors can increase the risk of falls in affected subjects. A non-randomized and non-controlled study showed that a diet and exercise intervention in patients with diabetes led to an overall improvement in autonomic function. Furthermore, it was shown that standing balance can be improved with a balance intervention program. However, there are no published studies that assess the effect of an intense physical activity intervention on autonomic function in IGR related neuropathy. This study will test an aerobic exercise and balance intervention in participants with IGR. The investigators will examine if an individually tailored, carefully monitored, Diet, Physical Activity, and Balance Enhancement Program (DPAEP) can improve autonomic function and balance control when compared to patients who receive standard care. Improving balance control and autonomic function can decrease the risk of falls and have a significant effect on the health of participants. The research is also significant because it will test subjects either before they become diabetic, or at an early stage in their diabetes, thus enhancing the chance of reversing the autonomic neuropathy or balance impairment. Furthermore, the study is designed to test whether improvement in autonomic function and balance is associated with improvement in clinical outcomes, quality of life, and the metabolic state of participants. Thus, the proposed interventions are likely to have a real life impact on participants and their health.
This study will look at whether or not the medication exenatide improves signs and symptoms of diabetic peripheral neuropathy in people with type 2 diabetes and mild to moderate diabetic peripheral neuropathy.
The purpose of this study is to conduct an interventional, one year, randomized, double blind, placebo-controlled trial with Liraglutide in patients with type 2 diabetes (diabetes duration of \>6 months and \<10 years, HbA1c \<10%) to evaluate its effects on the peripheral autonomic nervous system, as well as inflammatory markers, and measures of oxidative and nitrosative stress.
The purpose of this study is to see whether droxidopa is effective in treating symptoms of neurogenic orthostatic hypotension in patients with Primary Autonomic Failure (Pure Autonomic Failure, Multiple System Atrophy, Parkinson's Disease), Non-diabetic neuropathy, or Beta Hydroxylase deficiency.
