This study will examine if one of the following methods: pupillometry, spectral analysis of heart rate variability and metaiodobenzylguanidine scintigraphy, is more capable to detect early diabetic autonomic neuropathy in patients with type 1 diabetes mellitus

Effect of DPP-IV Inhibitor on Glycemic Control and Autonomic Neuropathy in Adult Patients With Diabetes Mellitus
Rocca et al. reported first that the secretion of incretins, particular GLP-1 in rat is regulated by the enteric nervous system, the afferent and efferent vagus nerves [1]. Further, Kazakos et al. [2] reported that autonomic nerve disturbance (AND) in patients with T2DM impaired the incretin effect owing to decreased GLP-1 secretion. However, Toft-Nielsen et al. [3] reported that the decreased GLP-1 responses in the patients with type 2 diabetes mellitus (T2DM) are unlikely to be related to the AND and, thus, did not support the results of Rocca et al. and Kazakos et al. Recently, Yabe at al. [4] also observed the same observations in Japanese patients with T2DM. Meanwhile, Jin et al. reported that administration of DPP-IV inhibitor recovered the disturbance of diabetic nerve dysfunction in rat [5]. However, it is unknown whether the administration of DPP-IV inhibitor effects on the AND in human, although many studies are performed to investigate the effect of the DPP-IV inhibitors on glycemic control. Accordingly, it is significant to reinvestigate an effect of DPP-IV inhibitor on glycemic control and autonomic neuropathy in diabetic patients.

Central and Peripheral 24h BP and the Association to Autonomic Neuropathy and Diabetic Nephropathy in Type 1 Diabetic Patients
The aim of the study is to evaluate the prevalence of abnormal nocturnal blood pressure (BP) in patients with type 1 diabetes. The investigators wish to gain knowledge on the relation between central and peripheral 24 hour BP and a possible association to late complications in diabetes.

Improving Autonomic Function and Balance in Diabetic Neuropathy
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.
