There are 3 clinical trials
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.

Measure: Non-pain Neuropathic Signs (UENS) Time: Baseline week [Day-7 to Day 1] compared to Week 12Peripheral neuropathy affects about 50% of the diabetic population and there is no treatment other than good blood glucose control, which is ineffective in subjects with type 2 diabetes. Part of the problem for the lack of an effective treatment is the inability to detect peripheral neuropathy in its early stage. The hypotheses to be addressed in the first phase of this study is that changes in cornea sensitivity (blinking and squinting) following addition of a hyperosmotic solution will provide a novel screening tool for early diagnosis of peripheral neuropathy. For the second phase of the study the investigators will examine the effect of fish oil treatment of diabetic subjects with neuropathy on corneal nerve density and sensitivity. Corneal nerves are the most highly innervated part of the human body with great sensitivity. The first phase will use this property and determine whether sensitivity is lost in diabetic patients with neuropathy. Preclinical studies have supported this hypothesis and now this will be tested in human subjects. Preclinical studies have also shown that treating diabetic rodents with fish oil improves nerve regeneration and outcome measures of peripheral in diabetic rodents. In the second phase the investigators will perform preliminary studies in human subjects with diabetic neuropathy and determine whether treating them with fish oil increases corneal nerve density and sensitivity.
Description: A recording of the eyes will be performed using a multi-camera video platform for a period of 150 seconds at four different time points. The first will be a baseline, second after a drop of isotonic saline and 3 and 4 after drops of 2 increasing concentrations of Muro 128 (2% sodium chloride, and 5% sodium chloride). Each of these will be separated by a 5 minute rest period. After, this is completed each subject will also be asked to record their sense of pain to each eye drop solution on a scale of 1 to 10. Squinting (an analysis of the amount of time a extent that the eye is closed) and blinking (number of blinks during the procedure) will be quantified during each time point using an image analysis program which analyzes the recorded digital video frames.
Measure: Change in corneal sensitivity to hyperosmotic eye drop Time: Done once as the primary outcome of phase 1 of the study and again at the end of the study after 12 months of fish oil treatment.Description: This is a primary endpoint for phase 2 of the study. Prior to beginning treatment with fish oil and 1 year later after fish oil intervention is complete the subjects cornea nerve density will be determined using cornea confocal microscopy. This is a non-invasive procedure that takes images on the sub-epithelial layer of the cornea. Six images will be collected at each of the two visits. From these images the total corneal nerve length will be determined and reported as mm/mm2

The subject will remove their footwear and lie down on a table. The filament will be applied perpendicular to the skin surface on the bottom of the feet will sufficient force to allow the filament to bend. Each subject will be asked to tell the examiner if they feel it. A lack of sensation is a marker for diabetic neuropathy.
Measure: Change in 10 g monofilament test Time: Done once as a baseline measurement for phase 2 of the study and again at the end of the study after 12 months of fish oil treatment.Description: Vibratory sensation is a standard of care test used with patients with diabetes to test sensory nerve sensation. A 129 Hz tuning fork is used and placed over the dorsum of the great toe on the boney prominence of the distal interphalangeal joint. The subject is asked to tell the examiner if they feel the object touching their toe. A lack of sensation is a marker for diabetic neuropathy.
Measure: Change in vibratory sensation of the great toe. Time: Done once as a baseline measurement for phase 2 of the study and again at the end of the study after 12 months of fish oil treatment.Description: Reflex testing is commonly used to detect sensory neuropathy in diabetic patients. The ankle reflex is examined by aligning the subjects ankle into a neutral position and the examiner strikes the Achilles tendon with a neurological hammer. An abnormal result is recorded if the subject does not display any ankle plantarflexion.
Measure: Change in reflex testing Time: Done once as a baseline measurement for phase 2 of the study and again at the end of the study after 12 months of fish oil treatment.Description: Cold and warm thresholds measure response of A-delta and C fibers of sensory nerves. A Velcro strap containing a metal circular pad about the size of a half dollar is attached to the dorsal part of the right foot. The subject is asked to push a button on a hand held device when they feel hot or cold from the circular pad attached to their foot. The device is set to default before any damaging temperature is reached. First warm followed by cold will be tested and the temperature of the pad will be recorded when the patient pushes the button. The commercial TSA-II Neurosensory Analyzer will be used.
