Of the various types of diabetes mellitus, non-insulin-dependent diabetes NIDDM is by far the most common and is increasing rapidly in many populations around the niddm.

Diabetes Care 1 March ; 15 3 : — Non-insulin-dependent diabetes mellitus NIDDM results from an imbalance between insulin sensitivity and insulin secretion. Both longitudinal and cross-sectional studies have demonstrated that the earliest detectable abnormality in NIDDM is an impairment in the body's ability to respond to insulin. Because the pancreas is able to appropriately augment its secretion of insulin to offset the insulin resistance, glucose tolerance remains normal. In the postabsorptive state hepatic glucose output is normal or increased, despite the presence of fasting hyperinsulinemia, whereas the efficiency of tissue glucose uptake is reduced. In response to both endogenously secreted or exogenously administered insulin, hepatic glucose production fails to suppress normally and muscle glucose uptake is diminished.

Several lines of evidence indicate that NIDDM is a heterogeneous disease that results from a combination of abnormalities in both insulin secretion and insulin action. There is increasing interest in using a combined determination of immunological markers of IDDM for the identification of subjects at risk of developing clinical IDDM in first degree relatives of IDDM patients and in the general population. It is hypothesized that the presence of a combination of immunological markers of autoimmune diabetes such as autoantibodies to GAD, IA-2 and insulin, in the serum of patients should predict a more rapid loss in beta-cell function, and subsequent insulin dependency, in a subgroup of NIDDM patients who have beta-cell autoimmunity. To determine who among these individuals will be more prone to develop the disease and consequently be exposed to its pathologic consequences, including for example, heart failure, the Institute will recruit approximately NIDDM patients per year. Glycemic control will be assessed by periodic monitoring of glycated hemoglobin; a minute intravenous glucose tolerance test IVGTT to assess first phase insulin release FPIR ; C-peptide and total insulin; as well as by home blood glucose monitoring performed by the patients. Each subject will have an HLA typing and an annual examination of beta-cell autoimmunity markers. This study will provide information regarding the feasibility to predict a loss of beta-cell function in patients clinically diagnosed with NIDDM by using a combined analysis of immunological as well as genetic markers of beta-cell autoimmunity and will give new insight for the selection of candidates for safe prevention of insulin dependency among NIDDM patients. In healthy nondiabetic individuals, FFA are the predominant oxidative substrate of skeletal muscle during post-absorptive conditions. Gas exchange across the leg was measured to perform regional indirect calorimetry in order to determine leg glucose and lipid oxidation. In more recent clinical investigations involving limb balance studies, we have added measurements of FFA fractional extraction and uptake across the leg by determining arterio-venous differences of 3H-palmitate assayed by HPLC. The second hypothesis is that activity of muscle carnitine-palmitoyl transferase CPTI is reduced in NIDDM, caused by allosteric inhibition from muscle malonyl CoA, which we postulate to be increased due to hyperglycemia. The hypothesis that FFA uptake is reduced by hyperglycemia during post-absorptive conditions can be tested in two clinical investigations.

In addition, people with NIDDM and poor niddm control may develop severe microvascular complications of diabetes, including retinopathy, nephropathy and neuropathy. Email alerts Article Activity Alert. Email alerts Article Activity Alert, niddm.

Diabetes Care 1 April ; 20 4 : — Subjects were randomized by clinic into a clinical trial, either to a control group or to one of three active treatment groups: diet only, exercise only, or diet plus exercise. Follow-up evaluation examinations were conducted at 2-year intervals over a 6-year period to identify subjects who developed NIDDM. Cox's proportional hazard analysis was used to determine if the incidence of NIDDM varied by treatment assignment. The cumulative incidence of diabetes at 6 years was Sign In or Create an Account.

In response to both endogenously secreted or exogenously administered insulin, hepatic glucose production fails to suppress normally and muscle glucose uptake is diminished. The accelerated rate of hepatic glucose output is due entirely to augmented gluconeogenesis.

Type 2 diabetes is a condition that happens because of a problem in the way the body regulates and uses sugar as a fuel. That sugar also is called glucose. This long-term condition results in too much sugar circulating in the blood.

In NIDDM subjects, post-absorptive leg FFA uptake and oxidation is assessed during fasting hyperglycemia and after overnight euglycemia, and compared to respective rates in nondiabetics. Gas exchange across the leg was measured to perform regional indirect calorimetry in order to determine leg glucose and lipid oxidation. Leg balance methods to measure glucose uptake, net lactate balance, limb indirect calorimetry leg gas exchange , fractional extraction of palmitate and blood flow are used to ascertain skeletal muscle metabolism. During 40 minutes of moderate intensity exercise 40 percent of maximal VO2 , rates of systemic glucose and FFA utilization and oxidation are determined in NIDDM subjects and in obese and nonobese nondiabetics. Information for Researchers. Of the various types of diabetes mellitus, non-insulin-dependent diabetes NIDDM is by far the most common and is increasing rapidly in many populations around the world. With these early results, we have now created islet hyperfunction in other transgenic mice using related growth factors. In healthy nondiabetic individuals, FFA are the predominant oxidative substrate of skeletal muscle during post-absorptive conditions. Several lines of evidence indicate that NIDDM is a heterogeneous disease that results from a combination of abnormalities in both insulin secretion and insulin action.
