Definitions

  • Diabetes adversely affects the way the body uses sugars and starches which, during digestion, are converted into glucose. Diabetes mellitus is generally caused in almost all instances by diminished rates of insulin secretion (absolute or relative) by the beta cells of the islets of Langerhans in the pancreas or by reduced insulin sensitivity. Insulin, a hormone produced by the pancreas, makes the glucose available to the body's cells for energy. In muscle, adipose (fat), and connective tissues, insulin facilitates the entry of glucose into the cells by an action on the cell membranes. The ingested glucose is normally converted in the liver to CO 2 and H 2 O (50%); to glycogen (5%); and to fat (30-40%), the latter being stored in fat depots. Fatty acids from the adipose tissues are circulated, returned to the liver for re- synthesis of triacylglycerol and metabolized to ketone bodies for utilization by the tissues. The fatty acids are also metabolized by other organs.
  • Type 1 diabetes juvenile-onset, insulin-dependent diabetes mellitus [IDDM]
  • IDDM insulin-dependent diabetes mellitus
  • Type 1 diabetes the pancreas produces little or no insulin, and insulin must be injected daily.
  • Type 2 diabetes the pancreas retains the ability to produce insulin and in fact may produce higher than normal amounts of insulin, but the amount of insulin is relatively insufficient, or less than fully effective, because of cellular resistance to insulin.
  • Type 2 diabetes may present as non-obese NIDDM, obese NIDDM, or maturity-onset diabetes of the young (MODY).
  • Type 1 is likely to occur in those with a family history of diabetes and is characterized by blurred vision, itching, unusual thirst, drowsiness, obesity, fatigue, skin infections, slow healing, and tingling or numbness in the feet.
  • Type I Diabetes Type 1 diabetes accounts for around ten percent of all cases of diabetes mellitus.
  • the action of Type 1 diabetes is to cause hyperglycemia (elevated blood glucose concentration) and a tendency towards diabetic ketoacidosis (DKA).
  • DKA diabetic ketoacidosis
  • Treatment requires chronic administration of insulin. No single standard exists for patterns of administration of insulin and treatment plans vary and may be selected from one of three treatment regimens: conventional, multiple subcutaneous injections, or continuous subcutaneous insulin infusion.
  • Conventional insulin therapy involves the administration of one or two injections a day of intermediate-activity insulin such as zinc insulin or isophane insulin with or without the addition of small amounts of regular insulin.
  • Regular insulin has a duration of action lasting from 3 to 8 hours, whereas other forms of insulin are absorbed slowly from the injection site and therefore have effects that may last as long as ten to forty-eight hours.
  • the multiple subcutaneous insulin injection technique involves administration of intermediate- or long- acting insulin in the evening as a single dose together with regular insulin prior to each meal.
  • Continuous subcutaneous insulin infusion involves the use of a small battery-driven pump that delivers insulin subcutaneously into the abdominal wall, usually through a butterfly needle. Insulin is delivered at a basal rate continuously throughout the day, with increased rates programmed prior to meals. Insulin may also be delivered by way of an implant that is administered parenterally, or by way of slow-release formulations.
  • Type 2 Diabetes Type 2 diabetes is marked by hyperglycemia that is not linked with DKA. Sporadic or persistent incidence of hyperglycemia may be controlled by administering insulin. Uncontrolled hyperglycemia may transiently adversely affect the insulin-producing cells of the pancreas (the beta-islet cells), which may eventually result in greater insulin deficiencies.
  • the fundamental defects to which such abnormalities may be traced include (1 ) a reduced entry of glucose into various "peripheral" tissues, and (2) an increased liberation of glucose into the circulation from the liver. There is therefore an extracellular glucose excess and an intracellular glucose deficiency. There is also a decrease in the entry of amino acids into muscle and an increase in lipolysis. The cumulative effect of these diabetes-associated abnormalities may be severe blood vessel and nerve damage.
  • 2 diabetic subjects may be treated with insulin, if necessary.
  • Type 2 often develops in subjects of certain at risk populations. Obesity predisposes an individual to Type 2 diabetes due to long-term effects on insulin resistance. If the beta- cells are compromised, diabetes may well ensue. Type 2 also develops from the at risk population of individuals with gestational diabetes mellitus (GDM). Pregnancy normally is associated with progressive resistance to insulin-mediated glucose disposal. In fact, insulin sensitivity is lower during late pregnancy than in nearly all other physiological conditions. The insulin resistance is thought to be mediated in large part by the effects of circulating hormones such as placental lactogen, progesterone, and cortisol, all of which are elevated during pregnancy.
  • GDM gestational diabetes mellitus
  • pancreatic beta-cell responsiveness to glucose normally increases nearly 3-fold by late pregnancy, a response that serves to minimize the effect of insulin resistance on circulating glucose levels.
  • pregnancy provides a major "stress-test" of the capacity for beta-cells to compensate for insulin resistance.
  • Type 2 diabetes Other populations thought to be at risk for developing Type 2 diabetes are the elderly; certain minorities; persons with Syndrome X; persons with concomitant hyperinsulinemia; persons with insulin resistance characterized by hyperinsulinemia and by failure to respond to exogenous insulin; and persons with abnormal insulin and/or evidence of glucose disorders associated with excess circulating glucocorticoids, growth hormone, catecholamines, glucagon, parathyroid hormone, and other insulin-resistant conditions.
  • Diabetes has become a leading health care issue in the United States and other countries, accounting for one seventh of the national health care budget.
  • the incidence of diagnosed diabetes has increased five-fold in America over the past 35 years, with currently 8 million diagnosed diabetic patients, another estimated 8 to 12 million undiagnosed diabetic individuals, and still an additional 23 million Americans with pre-diabetes, or impaired glucose tolerance (IGT).
  • ITT impaired glucose tolerance
  • the American populace continues its trend towards aging, obesity, and greater minority representation, the number of individuals who are diabetic and suffer from other glucose metabolism disorders is likely to increase.
  • Diabetic Complications and Symptoms Although progress has been made in reducing the short term complications of diabetes, e.g. ketoacidosis, dehydration, and non-ketotic hyperosmolar coma, less progress has been made in preventing or minimizing the chronic complications of the disease, e.g. premature atherosclerosis, retinopathy, nephropathy, and neuropathy. It is estimated that a diabetic patient's life is shortened by 10 to 15 years, and those years of life are distinguished by significantly increased medical care costs as compared to a non-diabetic patient. Some complications of diabetes includes blindness and end-stage renal disease.
  • diabetes mellitus Another complication of diabetes mellitus is diabetic neuropathy (also called neuritis), which has been an unusually refractive complication of diabetes. Endoneural hypoxia is the overt cause of diabetic neuropathy. Early symptoms include numbness, irritation, and pain, usually in the extremities, and more advanced ones include gastroparesis and impotence.
  • EFA essential fatty acid
  • GLA gamma-linolenic acid
  • Prostacyclin is a vasoprotective molecule with multiple physiological functions, and the enzyme cyclooxygenase (cox) is involved in its synthesis.
  • cox-1 which produces both prostacyclin and anti-inflammatory prostaglandins
  • cox-2 which produces both thromboxane A, (TxA 2 ) and some of the prostaglandins responsible for inflammation.
  • neurotrophic factors such as the superfamiliy of neurotrophins including nerve growth factor, may present an alternative pathogenic mechanism that results in neuropathy.
  • Another complication of diabetes is increased cardiovascular risk factor, especially among women.
  • a man's risk of dying by heart disease doubles upon developing diabetes, whereas a woman's risk increases three to five-fold.
  • Type 2 diabetes presents a number of co-existent cardiovascular metabolic risk factors, e.g., insulin resistance, hyperinsulinemia, central obesity, hypertriglyceridemia, low HDL level, qualitatively abnormal LDL (diabetic dyslipidemia), hypertension, glucose intolerance, and elevated blood pressure.
  • cardiovascular metabolic risk factors e.g., insulin resistance, hyperinsulinemia, central obesity, hypertriglyceridemia, low HDL level, qualitatively abnormal LDL (diabetic dyslipidemia), hypertension, glucose intolerance, and elevated blood pressure.
  • This state has been identified as "Syndrome X.”
  • These cardiovascular risk factors may precede the onset of diabetes by as much as a decade, and they may explain the presence of overt clinical cardiovascular disease in as many as 60% of newly diagnosed diabetic patients.
  • elevated glycated hemoglobin (HbAlc) is believed to be a risk marker for short-term mortality following acute myocardial infarction in non-diabetic subjects.
  • Diabetic dyslipidemia is another complication of diabetes and is of import to cardiovascular health.
  • Plasma cholesterol and triglycerides are transported in lipoproteins (HDL, VLDL, and LDL).
  • Dyslipoproteinemias are conditions in which the concentration and composition of these cholesterol- or triglyceride-carrying lipoproteins are abnormal. Elevated concentration of lipoproteins LDL and VLDL may accelerate the development of atherosclerosis, with the secondary possibilities of thrombosis and infarction. Evidence suggests that reduction of the concentration of lipoproteins LDL and VLDL in plasma may diminish the increased risk of atherosclerosis that accompanies hyperlipoproteinemia.
  • Dyslipoproteinemias have been designated as either primary or secondary.
  • dyslipoproteinemias involve complications of a more generalized metabolic disturbance, such as diabetes mellitus or excessive intake of ethanol.
  • primary dyslipoproteinemias are typically caused either by an inherited single-gene defect (monogenic dyslipoproteinemias) or a combination of multiple subtle genetic factors that act together with environmental ones (multifactorial or polygenic dyslipoproteinemias).
  • cardiac mortality there may be an excessive risk of cardiac mortality in diabetic patients even after adjusting for the co-existence of other cardiovascular risk factors such as hypertension, dyslipidemia, and cigarette smoking.
  • This increase risk of cardiac mortality is secondary to both the atherogenicity of insulin resistance, which may precede the onset of diabetes by at least 8 years, and the atherogenicity of undiagnosed and uncontrolled hyperglycemia, which may be present for 9-12 years before diabetes is first diagnosed.
  • One means of attenuating the cardiovascular effects of diabetes would involve earlier diagnosis and improved management of diabetes to reduce insulin resistance and control blood glucose. To this end, screening for risk factors for vascular complications followed by appropriate treatment may be appropriate.
  • alpha-glucosidase inhibitors competitively inhibit alpha- glucosidase, which metabolizes carbohydrates, thereby delaying carbohydrate absorption and attenuating post-prandial hyperglycemia.
  • therapies for treatment of diabetes that have not yet been approved for human use.

  • the diabetic patient may be at risk for developing magnesium depletion via inadequate dietary intake and gastrointestinal and renal losses, especially with poorly controlled blood glucose and resultant glucosuria.
  • the diagnosing magnesium deficiency in the clinical setting remains extremely difficult because serum magnesium measures only 0.3% of the total body magnesium and is therefore difficult to determine.
  • Magnesium appears to improve glucose metabolism and to arrest or reduce any diabetes associated risk factors. Many preparations of magnesium are available but they may differ in potency, bioavailability (absorption), tolerability, and cost. Magnesium taken orally is absorbed primarily in the jejunum and ileum. Some magnesium salts, such as the oxide or the carbonate, although inexpensive, are not highly soluble in water, poorly absorbed and associated with gastrointestinal side effects, especially diarrhea. Other magnesium-containing complexes present better solubility, bioavailability, potency, tolerability, safety, and predictability in repleting intracellular and serum levels of

  • Magnesium acetate, magnesium ascorbate and magnesium lactate are soluble in gastric fluid and share the upper gastrointestinal passive absorption potential of magnesium citrate.
  • the ascorbate radical serves as a source of vitamin C by conversion to ascorbic acid upon exposure to hydrochloric acid in the gastric fluid, whereas the magnesium ion is converted to soluble magnesium chloride.
  • the satisfactory water solubility of magnesium acetate, magnesium ascorbate, magnesium citrate and magnesium lactate provide for a diffusional gradient of magnesium in the upper small intestine where some passive absorption of magnesium occurs.
  • Magnesium oxide is converted to magnesium chloride in the stomach, and offers the advantage of a high ionic magnesium content, since 60% by weight of the magnesium oxide molecule is elemental magnesium

  • Aspi ⁇ n may be use to reduce the ⁇ sk of either p ⁇ mary (high risk for cardiovascular disease) or secondary (cardiovascular disease)
  • the health promoting benefits of aspirin derive in part from its antiplatelet effect. It appears to work, in part, by inhibiting cyclooxygenase, an enzyme necessary for the synthesis of thromboxane, a potent stimulator of platelet aggregation, a condition known to be increased in diabetes and to be causative in the atherosclerotic process. In patients with diabetes and other glucose metabolism disorders, aspirin appears to co ⁇ ect this abnormal increase in platelet activity.
  • Platelet aggregation is implicated in thrombus formation, which involves interaction of aggregated platelets and activated coagulation factors with a damaged vascular wall. Platelets are normally non-adherent, but upon damage to the endothelial lining of a vessel, the platelets adhere to exposed subendothelial collagen. The von Willebrand factor (vWF) is involved in this adhesion. Collagen and thrombin initiate platelet activation and activate phospholipase C, which hydrolyzes membrane phospholipids. Protein kinase C is thereby activated, and the calcium concentration of platelet cytosol increases.
  • vWF von Willebrand factor
  • Arachidonic acid is liberated from membrane phospholipids and is oxidized in part to prostaglandin H 2 (PGH 2 ) and TxA 2 . After platelet aggregation, fibrinogen is converted to fibrin to secure the hemostatic platelet plug. Platelet aggregation is mediated by the PGH, derivative prostacyclin, which is also a vasodilator. In the arachidonic acid cascade, aspirin acts as a cyclooxygenase inhibitor, blocking the conversion of arachidonic acid to the PGH 2 precursor prostaglandin G 2 (PGG 2 ).
  • PGG 2 is a precursor to both TxA 2 and prostacyclin
  • aspirin blocks both the aggregation inducing and aggregation inhibiting effects of these factors.
  • naproxen, indomethacin, piroxicam and acetaminophen inhibit production of the pain-producing prostaglandins by cox-2, but they all, other than aspirin, substantially inhibit cox-1 , which produces prostacyclin.
  • Aspirin inhibits prostacyclin production the least (3-4 hrs), and piroxicam the most (3-4 days). It is believed that that one aspirin taken every 3 days maximizes prostacyclin production and minimizes production of TxA 2 , which causes hypertension and has been implicated in development of vascular disease.

  • Vitamin E supplementation reduces significantly atherosclerosis in primates, including humans. This observation assumes greater importance in those with diabetes, in view of the fact that as many as 60% of newly diagnosed diabetic patients already have clinically obvious cardiovascular disease. A number of studies confirm such observation/ A significantly lower risk of coronary artery disease was observed in a four year, prospective, observational study in healthy middle-aged men who had higher intakes of dietary vitamin E as compared to those consuming small amounts. In another prospective, epidemiological study, middle-aged women free of cardiovascular disease at baseline were found to have a highly significant reduced risk of coronary artery disease if they had been on vitamin E supplements for at least two years during the eight year study. In a more recent and similar seven year prospective study of postmenopausal women without cardiovascular disease, dietary vitamin E consumption, but not vitamin A or C, was inversely associated with the risk of death from coronary artery disease.
