Detailed Description:

The prevalence of diabetes mellitus is increasing recently, especially in the urban area of developing countries. Subjects with diabetes have higher rate of hospitalization and have higher mortality. Diabetes results in various complications including diabetic retinopathy, nephropathy, neuropathy, and cardiovascular complications. Among these, cardiovascular autonomic neuropathy is one of clinical important complication of diabetes. Diabetic subjects with reduced cardiovascular autonomic function have been shown to strongly associate with an increased risk of silent myocardial ischemia and increased mortality. They also have higher risk of sudden death, intraoperative and perioperative cardiovascular instability. Formation of advanced glycation end product (AGE) and oxidative stress are important causes of diabetic neuropathy. Vascular adhesion protein-1 (VAP-1), an adhesion molecule with an activity of semicarbazide-sensitive amine oxidases (SSAO), which can catalyze endogenous amines to produces corresponding aldehydes, H2O2, and ammonia. We have demonstrated that serum VAP-1 is a source of systemic AGE and oxidative stress, and is associated with nephropathy and atherosclerosis. There are reports demonstrating that subjects with diabetic retinopathy or stroke have higher serum VAP-1. To our best knowledge, there is no report regarding the relationship between serum VAP-1 and neuropathy. In present study, we will measure serum VAP-1 and check cardiovascular autonomic function. We will also explore the relationship between serum VAP-1 and cardiovascular autonomic neuropathy in subjects with type 2 diabetes mellitus.
