Filter by:Diabetic peripheral neuropathy (DPN) occurs due to long standing hyperglycemia and associated metabolic derangements. Cognitive impairment is a common complication in diabetes mellitus. It is associated with a faster rate of cognitive decline.
Peripheral 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.
The objectives of the MEDIAN study are to evaluate the short-term and long-term safety and nutritional benefits of Metanx® versus placebo in subjects with mild to moderate diabetic peripheral neuropathy (DPN). Short-term effects will be evaluated during the first 16 weeks of treatment, and long-term effects will be evaluated over the duration of a 48 week treatment period.
