The Team Approach

Diabetes centers provide point-of-care testing (POCT) for consistent and regular management of glycemia and monitor markers that predict the development of hyperglycemia-related pathology. At diabetes centers and other facilities that provide preventive care for patients with chronic diseases, patients are helped to take responsibility to monitor their illness and plan activities to improve long-term outcome of the pathological consequences of the disease process. Such facilities help to reduce the progression of disease toward secondary complications and mortality. Patients receive education and support to make appropriate lifestyle changes. Medical personnel are available to monitor risk factors on a regular basis. POCT provides rapid biochemical analysis in a timely manner, allowing necessary changes to therapy during the patient visit.

Inhibition Of Parp Activity For Beta Cell Protection

The injection of a single dose of 160 to 200 mg streptozocin kg body weight (BW) to mice or 50 to 80 mg streptozocin kg BW to rats causes acute beta cell toxicity and results in persisting hyperglycemia about 2 days after application.21 Therefore, the administration of a single high dose of streptozocin represents a useful experimental approach to target a toxic attack, involving primary nuclear DNA damage, to the pancreatic beta cells in vivo. The application of multiple subdiabetogenic doses of streptozocin in mice (5 x 35 to 40 mg streptozocin kg BW on 5 consecutive days) elicits an immune response against autologous pancreatic islet structures, resulting in insulitis, beta cell destruction, and the development of hyperglycemia.64 The intraperitoneal application of nicotinamide at a dose of 500 mg kg BW preserved beta cell function and protected from diabetes development in mice treated with streptozocin at a single high dose of 200 mg kg BW. The animals were protected from...

Effects of Weight Loss on MetS Components

Effective for long-term weight loss are reduced-energy diets, consisting of a 500- to 1000-calorie day reduction. A realistic goal for weight reduction is to reduce body weight by 7-10 over a period of 6 to 12 months. Numerous studies have shown that significant improvement of several abnormalities of MetS, including dyslipidemia, hyperglycemia, and hypertension, can be observed, even with a modest amount of weight loss.6,10 For every kilogram of weight loss the following favorable changes occur fasting serum cholesterol, -1.0 LDL cholesterol, -0.7 triglycerides,-1.9 HDL cholesterol, +0.2 systolic blood pressure, -0.5 diastolic blood pressure, -0.4 and fasting glucose, -0.2 mmol L. The impact of weight reduction on diabetes mellitus is particularly impressive.10

Iiiiiiiiiiiimiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiismu Li Glucagon is a peptide hormone involved in increasing blood

Glucagon stimulates transcription of the enzyme phosphoenolpyruvate carboxykinase (PEPCK). PEPCK is a key enzyme in gluconeogenesis and transcription is the primary means of regulating it. By stimulating PEPCK transcription, glucagon can favor gluconeogenesis over glycolysis. (Conversely, the hormone insulin, which decreases blood glucose levels, stimulates PEPCK transcription.)

Antisense Oligonucleotide Therapy

Two phase I trials were conducted to evaluate the safety and activity of oblimersen as a single agent in patients with NHL.51,52 The larger included 21 patients with Bcl-2-positive relapsed NHL who received a 14-day subcutaneous infusion.52 The median age was 54 years, nine had follicular NHL, eight had small lymphocytic NHL, three had large cell lymphoma, and one had mantle cell lymphoma. All patients had received multiple chemotherapy regimens and four patients had received high-dose chemotherapy and autologous stem cell transplantation. Oblimersen was delivered by a continuous subcutaneous infusion for 14 days at doses of 4.6-195. 8 mg m2 day. All patients experienced local skin inflammation at the sites of subcutaneous infusion. Dose limiting toxicities were observed at doses greater than 147.2 mg m2 day and consisted of thrombocy-topenia, fevers, and hypotension. Non-dose-limiting toxicities included hyperglycemia during the infusion, fatigue, and transient increases in liver...

Test Methodology 42 Ketones

Dehydration is a common occurrence in the ketoacidosis of diabetes. Hyper-glycemia produces hyperosmolarity. The hyperosmolar state initiates multiple physiological responses, including increased renal excretion of glucose and ketones, resulting in polyuria and fluid oncotic shifts. Eventually polydipsia, or excessive thirst, is triggered and, if fluid replacement occurs, the dehydration is minimized. Fluid replacement therapy along with restoring normoglycemia is often an aspect of restoring normal conditions to the patient in diabetic ketoacidosis.15 Brandon has shown poor glycemic control with episodes of postprandial hyperglycemia and early-morning hypoglycemia by self-monitoring blood glucose technique. His parents reported early difficulties in motivating Brandon to comply with daily home monitoring of blood glucose and his treatment

Non Histone Protein Acetylation Link To Diseases

Pathways Thyroid Hormone Receptors

A factor acetyltransferase ARD1 that makes it susceptible to proteosomal degradation (Jeong et al., 2002). Insulin receptor substrate proteins (IRS) are the key regulators of insulin action. IRS1 is acetylated and the acetylation enhances its phosphorylation, which mediates the down stream insulin dependent signaling. IRS1 is associated with HDAC2 and HDAC2 mediated deacetylation have the reverse effect. HDAC2 specific small molecular inhibitors may elevate insulin sensitivity in otherwise insulin resistant conditions (Kaiser and James, 2004). Hyperglycemia also activates p53 and p53-regulated genes leading to myocyte cell death (Fiordaliso et al., 2001). p53 acetylation, site specific phosphorylation levels goes up in response to stress induced conditions like hypoxia, anti metabolites, nuclear export inhibitors thereby maintaining cellular homeostasis. p300 CBP mediated acetylation is negatively regulated by MDM2. MDM2 recruits HDAC1 and decatylates p53 making it susceptible for...

Why Cyclonxan Use For Kidney Patients

First Pass Metabolism Repaglinide

The major safety concern is severe hypoglycemia, with the longer-acting agents carrying a greater risk. In the United Kingdom Prospective Diabetes Study (UKPDS), the proportion of patients experiencing major hypoglycemic episodes was 1.0 and 1.4 per year with chlorpropamide and glyburide, respectively, as compared to 0.7 with diet and 1.8 with insulin therapy (82).Sulfonylureas are for the most part subject to hepatic metabolism, yielding less active or inactive metabolites that are then eliminated through the kidney. Patients with impaired hepatic or renal function risk severe hypoglycemia because of accumulation of active drug in circulation. As with insulin, gain in body weight is common. The University Group Diabetes Program (UGDP) study found an increased risk of cardiovascular mortality associated with the treatment of type 2 diabetes with tolbutamide, although the methods used have been criticized. The UKPDS showed no increase in cardiac...

LMF as a Pleiotropic Mediator

Glucose metabolism is also affected by LMF. Treatment of ex-breeder male NMRI mice with LMF isolated from the urine of cachectic cancer patients caused a significant increase in glucose oxidation to CO2, compared with control mice receiving phosphate-buffered saline 25 . Glucose utilisation was elevated in brain, heart, BAT, and gastrocnemius muscle. The tissue glucose metabolic rate was increased almost threefold in brain, accounting for the ability of LMF to decrease blood glucose levels. LMF also increased overall lipid oxidation. There was a significant increase in lipid accumulation in plasma, liver, and white and brown adipose tissue after administration of LMF. These results provide further evidence that changes in carbohydrate metabolism and loss of adipose tissue, together with increased whole-body fatty acid oxidation in cachectic cancer patients, may arise from tumour production of LMF.

Inflammation and atherothrombosis

There is extensive literature supporting the role of inflammation in CAD. Hemodynamic forces from hypertension and oxidative stressors, such as tobacco and hyperglycemia, result in vascular endothelial injury. The attachment of leukocytes, transformation of monocytes into macrophages, and subsequent uptake of cholesterol lipoproteins initiate the fatty streak. Cytokine release from the fatty streak recruits further inflammatory cells (macrophages, mast cells, activated T cells), with resulting uptake and oxidation of low-density lipoprotein (LDL). These cytokines also stimulate smooth muscle cell proliferation and development of a collagenous fibrous cap that covers this inflammatory mixture to form the mature atherosclerotic plaque 2 .

Basic theoretical concepts

In this concept, the initial step is considered dysfunction of the endothelium, the innermost layer of the vasculature, by local disturbances of blood flow, along with metabolic and humoral risk factors (e.g. hyperglycemia, dyslipidemia, cigarette smoking, inflammation). These alterations of the endothelium perpetuate a series of events that culminate in the development of an atherosclerotic plaque.

Structure Of Biguanides

Nateglinide Sar

First introduced in the late 1950, metformin (Table 1.6) is best described as an antihyperglycemicagent because it does not normally cause hypoglycemia. It enhances insulin sensitivity and is not effective in the absence of insulin (118). Metformin lowers blood glucose levels in NIDDM patients by suppressing hepatic glucose output and enhancing peripheral glucose uptake, but the underlying mechairism(s) is not completely understood. Other biguanides produce similar effects, but concern over potential to cause lactic acidosis has largely led to their removal from the market. Physiology and Pharmacology. Used in treatment of type 2 diabetes, metformin has typically been found to reduce fasting hyperglycemia by 1 to 3.9 mmol L and HbAlc by 1 to 2 (3,119, 121, 122), approximately equally efficacious with sulfonylureas, and also to reduce postprandial hyperglycemia. As monotherapy, it generally does not induce hypoglycemia nor does it increase insulin secretion....

Definition of MetS and Health Implications

MetS (also called deadly quartet, syndrome X, insulin resistance syndrome, plurimetabolic syndrome, dysmetabolic syndrome, cardiometabolic syndrome) comprises a cluster of abnormalities that occur as a result of perturbations in multiple metabolic pathways, leading to insulin resistance and hyperinsulinemia, hyperglycemia, athero-genic dyslipidemia, hypertension, fibrinolytic abnormalities, etc.3 Numerous other disturbances have been progressively added to the syndrome, including a prothrombotic state, endothelial dysfunction and inflammation, all conditions associated with cardiovascular diseases (CVD). In 1998, the World Health Organization (WHO) recommended a unifying definition and chose the term metabolic syndrome (MetS). However, an alternative definition has been proposed in 2001 by the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III).14 This definition is easier to use in clinical practice and now widely accepted.3 According to this definition,...

Disorders Of Water Balance

Osmotic diuresis and psychogenic polydipsia can also cause polyuria. In osmotic diuresis, hypertonicity of plasma is usually the cause, such as in diabetes mellitus with hyperglycemia and ketosis. Thus diabetes mellitus can cause polyuria and poly-dipsia, but the serum and urine are hyperosmolar due to excessive glucose and ketones. In psychogenic polydipsia, the psychological disorder induces the patient to have chronic excessive fluid intake, which induces polyuria. In either of these conditions, the polyuria is not due to ADH defects.

Highdose Dexamethasone Monotherapy

Dexamethasone, 20 mg m2 day on days 1-4, 9-12, and 17-20, induces responses in previously untreated patients with MM 40-50 of the time,55, 56 suggesting that dexamethasone accounts for most of the benefit derived from VAD and TD (described below). Dexamethasone monotherapy may be preferred for frail patients, since the toxicity is generally less than that seen with VAD or TD. Still, primary pulse dexam-ethasone treatment is somewhat more toxic than MP,57 and patients should be monitored closely for specific side effects, including hyperglycemia, gastrointestinal bleeding, mood disorder, insomnia, weight gain, increased susceptibility to infections, and rarely pancreatitis.58

Use Of Crystalloid Fluids In Surgical Procedures

Physiologic responses to perioperative crystalloid loading appear to be complex.The Starling equilibrium describes a simple relationship between capillary hydrostatic pressure and colloid osmotic pressure. However, multiple factors also influence net movement of fluid from capillaries from plasma into interstitium. Dilution of plasma colloid osmotic pressure by infusion of an isotonic crystalloid will increase fluid flux into the interstitium, which in turn will dilute interstitial colloid oncotic pressure and partially restore the gradient between plasma and interstitial colloid osmotic pressure. As fluid flux into the interstitium increases, lymphatic flow increases, which returns some interstitial protein to the vascular space (Drucker et al., 1981). Lung lymph flow has the capacity to increase vastly when challenged by lower plasma oncotic forces (Zarins et al., 1978 Kramer et al., 1983, Wareing et al., 1989). During hemorrhage, constriction of precapillary sphincters reduces...

Pharmacologic And Metabolic Effects On Stimulation Threshold

The stimulation threshold may demonstrate considerable variability over the normal 24-hour period, generally increasing during sleep and falling during the waking hours.54'55 The changes in threshold parallel fluctuations in autonomic tone and circulating catecholamines, and consequently there is a decreased threshold during exercise. The stimulation threshold is inversely related to the level of circulating corticosteroids. The stimulation threshold may increase following eating, during hyperglycemia, hypoxemia, hypercarbia, and metabolic aci-dosis or alkalosis.56-60 The stimulation threshold may increase dramatically during acute viral illnesses, especially in children. The concentration of serum electrolytes may also influence stimulation threshold. For instance, stimulation threshold typically rises during hyperkalemia.57-59

Corroborative Results From Genetic And Pharmacological Inactivation Of Parp

The PARP knockout mice also have been used extensively either to confirm or to explore the role of PARP activation in various animal models of human diseases. One of the early implications for its role in pathogenesis came from the finding that PARP activation was the culprit of streptozotocin-induced diabetes, an animal model to study type 1 diabetes.97 In P-islet cells, free radicals derived from streptozotocin catabolism damaged DNA and activated PARP. Consequently, depletion of NAD due to PARP activation prohibited the release of insulin and led to cell death, as PARP inhibitors such as nicotinamide and 3-aminobenzamide prevented stretptozo-tocin toxicity.98 Three groups have now independently replicated the studies in PARP knockout mice, and all demonstrated that PARP gene deletion renders mice resistant to P-islet cell destruction and hyperglycemia after streptozotocin treatment.36,45,46 In the nervous system, PARP activation was found to mediate glutamate excitotoxicity and...

High Anion Gap Metabolic Acidosis

The serum sodium level can be variable. Hyperglycemia causes water to move extracellularly, which can lead to hyponatremia. Similarly, phosphate levels can be variable in the presence of body store deficits with the extracellular movement of phosphate caused by catabolic state. Blood urea nitrogen (BUN) and creatinine levels are elevated, reflecting dehydration. Serum ace-toacetate may cause a false elevation in serum creatinine level because of interference with the assay. 2. Correction of hyperglycemia and, in turn, plasma osmolality counterregulatory hormones and hyperglycemia. Sudden reduction in hyperglycemia can lead to vascular collapse with shift of water intracellularly. To avoid this, initial replacement fluid should be isotonic normal saline (NS) to correct circulatory volume deficit. Over the first hour, 1-2 L of NS should be infused. Following this, total-body water deficit is corrected at the rate of 250-500 mL h. depending on the state of hydration. The composition of...

Choice Of Preparation

Soluble insulin inj. (neutral, regular insulin) is an aqueous solution of insulin. It is simple to use, being given s.c. 2-3 times a day, 30 min before meals. There is little risk of serious hypoglycaemic reaction if it is used sensibly. If a meal must be delayed, then the insulin injection should be delayed. The dose can easily be adjusted according to self-performed blood glucose measurements.4 For these reasons it is often used initially to balance diabetics needing insulin and always for the treatment of diabetic ketoacidosis. The biggest disadvantages of soluble insulin for long-term use are the need for frequent injections, and the occurrence of high blood glucose before breakfast.

Type 1 Diabetes Mellitus

T1DM results from an absolute deficiency of insulin due to the autoimmunologi-cal attack and destruction of the beta-cells. The present concept of the pathogenesis ofTIDM is mainly based on evidence from studies on the animal models of human T1DM. The diabetes-prone BioBreeding (BB-DP) rat spontaneously develops a diabetic syndrome with characteristics similar to the human T1DM. In the non-obese diabetic mice model (NOD), autoimmune diabetes can be transferred from a diabetic to a non-diabetic animal via T lymphocytes. This confirms that the T lymphocytes are the mediators of autoimmune diabetes in NOD mice. It seems that both glutamate decarboxylase-(GAD) and insulin-reactive T cells are diabetogenic in the NOD mice. Antibodies to the above antigens can be observed long before the manifestation of hyperglycemia. The major histocompatibility complex class II allele, HLA-DQ, is the major genetic element, conferring susceptibility to or protection from human T1DM. However, the...

Type 2 Diabetes Mellitus

Abnormalities in the four major organ systems involved in glucose homeostasis contribute to the hyperglycemia observed in T2DM. Knowledge of the precise molecular alterations associated with these abnormalities will be of great help for a successful disease prevention and treatment. troversial. Abnormalities in the four major organ systems involved in glucose homeostasis contribute to the hyperglycemia observed in T2DM. Knowledge of the precise molecular alterations associated with these abnormalities will be of great help for a successful disease prevention and treatment.

Impaired Insulin Secretion

In addition, altered beta-cell function is critical for the initial formation of islet amyloid fibrils. Progressive amyloid deposition and the eventual replacement of beta-cell mass by amyloid result in increased hyperglycemia. This in turn further aggravates beta-cell function. In T2DM, an overall reduction in insulin secretion is observed since beta-cells can no longer secrete sufficient insulin to maintain normal blood glucose levels. Development of beta-cell dysfunction and progression to complete beta-cell failure was attributed to a combination of beta-cell gene defects and environmental factors such as high fat diet leading to chronically increased FFA levels 26 . According to this model, beta-cell dysfunction is associated with the development of islet amyloid and subsequent reduction of the beta-cell mass. The resulting hyperglycemia further aggravates beta-cell function (Fig. 12.2). Autopsy studies revealed a reduction of the beta-cell mass of...

Impaired Insulin Action Insulin Resistance

Function, insulin resistance may be present for many years before the onset of overt hyperglycemia, because of a compensatory secretory response of the beta-cell. However, in individuals predisposed to T2DM, beta-cells either fail to compensate the developing insulin resistance or fail after compensating for some time due to exhaustion. Any defect in the control of hepatic glucose production and or peripheral glucose uptake could result in insulin resistance.

The Treatment of Diabetes Mellitus

In T1DM plasma insulin levels are low or absent and treatment with insulin is always necessary. Since it is not yet possible to mimic the normal function of a beta-cell, which precisely adjusts the rate of insulin secretion in response to biological needs, the treatment ofT1DM is complicated by episodes of hypoglycemia and hyperglycemia. Hypoglycemia can cause coma, and hyperglycemia increases the risk for diabetic complications in the form of eye disease, kidney disease, nervous system damage, and coronary artery disease and stroke 69 . intestine and therefore attenuate mealtime hyperglycemia 72 . Both biguanides and thiazolidinediones (TZDs) increase insulin sensitivity, although their mechanism and site of action are different. These agents may be used alone or in combination with each other or with insulin 73 . In the following we will focus on the TZDs, since they seem to be most promising to provide a long-term glycemic control. In addition, they are less likely than...

Diabetes Prevention in the NOD Mouse

Keeping in mind the narrow therapeutic window between the onset of hyper-glycemia and critical P-cell mass loss, only two published therapies, antilymphocyte serum and anti-CD3 antibody (13), have been demonstrated to reverse hyperglycemia in recently diabetic NOD mice, demonstrating the difficulties in treating overtly diabetic mice.

Hypoglycemic and Blood Lipid Lowering Effect

One of the traditional uses for O.sanctum is for treating diabetes. Experimental studies performed in the 1960's showed that basil leaves can decrease blood glucose in hyperglycemic rats. These results were confirmed kter by other studies which showed that oral administration of alcoholic extracts of O.sanctum leaves led to a marked lowering of blood sugar level in normal, glucose fed hyperglycemic and streptozotocin induced diabetic rats (Chattopadhyay 1993, Rai et al., 1997). In a randomized placebo-controlled, single blind trial performed on humans a significant decrease in fasting and postprandial blood glucose levels was found. The medication consisted of 2.50 g dried leaf powder of fresh leaves of O.sanctum and was given for 61 days. The fasting blood glucose fell by 21.0 mg dl and postprandial blood glucose fell by 15.8 mg dl. The urine glucose levels showed a similar trend. In addition the total cholesterol showed a mild reduction during the basil treatment period (Agrawal et...

Glucose - The liver produces glucose, both from its own glycogen stores and from gluconeogenesis, the latter using lactate and alanine from muscle, glycerol from adipose tissue, and the amino acids not needed for protein synthesis. An important role of liver is to buffer the level of blood glucose. It does this largely through the action of glucokinase, an enzyme peculiar to liver, with a high Km (about 10 mm) for glucose, and partly through a high-KM transport protein, the glucose transporter. Thus, liver is unique in being able to respond to high blood glucose levels by increasing the uptake and phosphorylation of glucose, which results eventually in its deposition as glycogen. Glucose-6-phosphate accumulation activates the D form of glycogen synthase. In addition, glucose itself binds to glycogen phosphorylase a, increasing the susceptibility of phosphorylase a to dephosphorylation (see Figure 13.18), with consequent inactivation. Thus, in addition to hormonal effects (see here),...

Experimental Control Of Oxidative Stress Pathways

Caloric restriction is the only reproducible experimental manipulation for extending lifespan in many species. Restriction of food intake by 30 to 50 below ad libitum levels during the early growth phase of life has been shown to produce significant increases in the mean lifespan of several species, including insects, mice, fish, and rats 98 . Moreover, calorically restricted rhesus monkeys showed physiological changes similar to those observed in rodents on a calorie-restricted diet. Both calorically restricted monkeys and rats are smaller, mature later, have lower blood glucose and insulin levels, lower body temperature, and increased daytime activity 99 . Although several theories have been proposed to explain the anti-aging effects of caloric restriction, one hypothesis proposes that it acts by decreasing oxidative stress. In support of this hypothesis, it has been shown that caloric restriction can stabilize mitochondrial function and reduce oxidative stress in brain cells 100 ....

Suberoylanilide Hydroxamic Acid Vorinostat

SAHA has been investigated in phase I clinical trials in hematological and non-hematological malignancies. The most common toxicities include fatigue, gastrointestinal symptoms, hyperglycemia, hypokalemia, anemia, and thrombocytopenia (29,30). Doses and schedules recommended for phase II studies include 300 mg po bid daily for 3 days a week, 400 mg po daily continuous, or 200 mg po bid daily continuous. The SAHA-related adverse events are generally rapidly reversible after study drug cessation. Inhibition of HDAC activity was achieved in peripheral blood mononuclear cells at the 200 mg dose level. At dose levels of 400 and 600 mg, the duration of HDAC inhibition lasted 10 or more hours. Tumor responses have been documented in patients with diffuse large B-cell lymphoma, laryngeal cancer, thyroid cancer, and mesothelioma. The FDA has recently approved SAHA (Zolinza, Mesck & Co., Inc.) for the treatment of cutaneous manifestations of cutaneous T-cell lymphoma (CTCL) in patients with...

Anti Islet Autoantibody Assays

Type 1A diabetes mellitus, as defined by an expert panel of the American Diabetes Association, is characterized by the presence of antiislet autoantibodies. The presence of islet autoantibodies in individuals who otherwise seem healthy denotes an increased risk for later development of type 1A diabetes. The early expression of insulin autoantibodies (IAAs) is associated with early development of diabetes in young children and NOD mice. IAAs appear early and then disappear at approximately the time of onset of hyperglycemia in most NOD mice.

Approach To Diabetes Mellitus Definitions

Diabetes mellitus is a general term for several different diseases that result in high blood sugar levels and that eventually lead to microvascular and macro vascular complications. The major classifications of diabetes mellitus are type I diabetes, type 2 diabetes, and gestational diabetes. Because of the lack of insulin, which is required for the metabolism of glucose, type I diabetics are prone to metabolize fats, with the resultant production of ketones. An extreme result of this process is diabetic ketoacidosis, a syndrome characterized by hyperglycemia, high levels of serum acetone, and an anion gap metabolic acidosis. This often occurs during times of physical stress, such as an infection or myocardial infarction, or when the patient does not use his or her insulin. Diabetic ketoacidosis is a medical emergency, requiring hospitalization, careful insulin management, correction of acidosis and electrolyte disturbances, and evaluation for the underlying cause of the condition....

Annexins And Diabetes

Diabetes is a chronic condition that can present in two different ways type-1 insulin-dependent diabetes or the more common type-2 insulin non-dependent diabetes. In both instances it is the resulting hyperglycemia that is thought to be primarily responsible for the disease facies. Although diabetes is a systemic condition that affects all parts of the body, for the purposes of this discussion the endothelium will be the main point of focus, since the most complete data regarding the role of annexins in diabetes have come from studies examining their actions in endothelial cells. There are thought to be four major effects of hyperglycemia on endothelial cells an increase in flux through the polyol pathway which leads to a depletion of NADPH and ultimately diminishes the cell's ability to produce protective anti-oxidants, an increase in conversion of glucosamine-6-phosphate to N-acetylglucosamine which leads to the formation of transcription factor-sugar adducts (which can affect...

Inulin and Diabetes Mellitus

There is a long history of inulin-containing plants being used to treat diabetes. The Greek physician Theophrastus used dandelion (Taraxacum officinale L.) to treat the condition, a plant also used as an early treatment in Eurasia. In North America, the root of elecampagne (Inula helenium L.) has historically been used to lower blood sugar levels (Tungland, 2003). In 1874, it was reported that no sugar appeared in the urine of diabetics who were given a daily inulin dose of 50 to 120 g (K lz, 1874). Jerusalem artichoke tubers are rich in inulin and fructooligosaccharides and are therefore an ideal item to include in diabetic diets. Jerusalem artichoke was fed to diabetic patients in the 1920s with promising results (e.g., Carpenter and Root, 1928). It proved beneficial when substituted for other carbohydrate foods, such as potatoes, over periods ranging from 6 days to several months. The increase in blood sugar after eating Jerusalem artichokes (0.02 to 0.07 in 3 h) was significantly...

Diseases Of The Adrenal Cortex

When the cortex region of the adrenal gland is overfunctioning, it is often due to a secreting adenoma, a benign hormone-secreting tumor. Primary hypercorti-solism is the name of this disorder because the disease resides in the primary organ of this endocrine structure, the adrenal cortex. It is associated with increased levels of cortisol throughout the day, loss of diurnal variation, and decreased levels of ACTH. ACTH is low due to the negative feedback response of the pituitary gland, which is functioning normally in primary hypercortisolism. Hypercortisolism in the adult is characterized by hyperglycemia and changes in fat and water distribution. Other characteristics include bruising and poor wound healing, weight gain, weakening of bones, and depression. The weight gain tends to be located in the middle of the body with accompanying muscle wasting, known as truncal obesity. Fat accumulation on the upper shoulders and collar bone causes a hump on the upper back and jutting...

Monitoring Glycemic Control In Diabetic Patients

Diabetes causes chronic high blood glucose leading to 1) hyperglycosylation of proteins and cellular structures, and 2) accumulation of toxic metabolites because of abnormal glucose metabolism (12). These metabolic disruptions lead to retinopathy, neuropathy, nephropathy, and other complications of the disease such that diabetes is the leading cause of blindness, end-stage renal disease, and lower-extremity amputations. Treatment of these disorders in the 16 million people in the United States with diabetes costs at least 100 billion annually, accounting for approx 15 of the national health care budget and 25 of Medicare costs (13). The Diabetes Control and Complications Trial (DCCT) (14) showed conclusively that intensive management of blood glucose, through frequent administration of insulin, markedly decreases the long-term complications of diabetes. The DCCT also concluded that glycohemoglobin is a good long-term indicator of average blood glucose and is therefore a good...

Clinical Correlation

Other hormones also affect carbohydrate metabolism. Epinephrine, a hormone that is released by the adrenal medulla at times of stress, inhibits insulin secretion and stimulates glycogenolysis and lipolysis. Glucocorticoids, such as cortisol, are released from the adrenal cortex to reduce blood glucose concentration by inhibiting gluconeogenesis the absorption of dietary glucose. Thyroxine, a thyroid hormone, increases glycogenolysis and gluconeogenesis and inhibits absorption of dietary glucose through the intestine.

Approach To Suspected Diabetic Ketoacidosis

DKA is a clinical syndrome that results when the triad of anion gap metabolic acidosis, hyperglycemia, and ketosis is present and is caused by a significant insulin deficiency. It is a medical emergency, with an overall mortality rate < 5 if patients receive prompt and appropriate medical treatment. The majority of episodes are preventable, and many of the deaths also are preventable with proper attention to detail during management. Diabetes is the condition of relative or absolute insulin deficiency. When there is a severe insulin deficiency and a relative excess of glucagon, lipolysis is enhanced, causing release of free fatty acids. Oxidation of the fatty acids produces ketones, such as acetoacetate and beta-hydroxybutyrate, which are organic acids and often referred to as ketoacids. The excess of these ketoacids can produce a life-threatening metabolic acidosis. In addition, hyperglycemia produces an osmotic diuresis, which causes severe volume depletion, and electrolyte...

Answers To Case 43 Diabetic Ketoacidosis

Summary A young woman presents with unintentional weight loss, nocturia, and polyuria, with hyperglycemia that likely represents new-onset diabetes mellitus. She is hypovolemic as a result of osmotic diuresis and has an anion gap metabolic acidosis, which is primarily caused by ketoacids. Her mental status and abdominal pain probably are manifestations of the metabolic acidosis and hyperosmolarity.

Diabetic Ketoacidosis

The clinical manifestations are the expected consequences of the major biochemical changes, hyperglycemia, glucosuria, and ketoacidosis. Hyperglycemia Early signs and symptoms represent exacerbations of the classic features of diabetes mellitus in poor control -thirst, polydipsia, polyuria, weakness, lethargy, and malaise. Glucosuria Hyperglycemia causes an osmotic diuresis with loss of Na+ and water, resulting in ECF volume contraction, low blood pressure, postural hypotension, and tachycardia. Anorexia, nausea, vomiting, and abdominal pain are frequent nonspecific gastrointestinal complaints, especially in children. These symptoms, together with abdominal tenderness, decreased bowel sounds, guarding, and leukocytosis, may be severe, mimicking an acute abdominal emergency. Rebound tenderness is usually (but not universally) absent - the presence of hyperglycemia and keto i nemia should signal the correct diagno iis. The cause for the abdominal pain is not entirely clear, but in some...

Approach To Suspected Diabetes Mellitus Definitions

Type I diabetes Caused by what is believed to be an autoimmune destruction of the pancreatic beta cells and complete loss of endogenous insulin production. The presentation of this type of diabetes usually is acute, with hyperglycemia and metabolic acidosis. These patients are dependent upon exogenous insulin delivery. Type 2 diabetes is believed to have a prolonged asymptomatic phase. During these years of asymptomatic hyperglycemia, however, organ damage begins to occur. Therefore, several organizations recommend screening of certain high-risk populations.

The incidence of cancer increases with age in humans and in laboratory animals alike, but patterns of age-related distribution of tumors is different for different tissues and different tumors. Aging may increase or decrease the susceptibility of individual tissues to early carcinogens and usually facilitates promotion and progression of carcinogenesis. Aging may predispose to cancer by two mechanisms tissue accumulation of cells in late stages of carcinogenesis and alterations in internal homeostasis, in particular, alterations in immune and endocrine system. Increased susceptibility to the effect of late-stage carcinogens is found both in aged animals and elderly humans, as predicted by the multistage model of carcinogenesis. Studies in mammals have led to the suggestion that hyperglycemia and hyperinsulinemia are important factors both in aging and in the development of cancer. Insulin insulin-like growth factor 1 (IGF-1) signaling molecules that have been linked to longevity...

Systemic Effects Periodontitis

An understanding ol the effects of other infections is useful in delineating the mechanisms by which periodontal infection influences glycemia. Acute bacterial and viral infections have been shown to increase insulin resistance and aggravate glycemic control.' litis occurs in individuals with diabetes and without. Systemic infections increase tissue resistance to insulin, preventing glucose from entering target cells, causing elevated blood glucose levels, and requiring increased pancreatic insulin production to maintain normoglycemia. Insulin resistance may persist for weeks or even months after the patient has recovered clinically from their illness. In the individual with type 2 diabetes, who already has significant insulin resistance, further tissue resistance to insulin induced by infection may considerably exacerbate poor glycemic control. In type 1 patients, normal insulin doses may be inadequate to maintain good glycemic control in the presence of infection-induced tissue...

Micronutrients CHD

Lowers LDL cholesterol and raises HDLs, thereby reducing risk of heart attack.13 Side effects (flushing) can be minimized by raising the dose gradually and taking the niacin with meals. Should betaken only under medical supervision at doses > 1 g day because of rare but potentially serious side effects, including liver inflammation and hyperglycemia


Diabetes is a chronic disease caused by inadequate secretion of, or peripheral resistance to, insulin. It is characterized by hyperglycemia and hyperlipidemia. Diabetes, when poorly controlled, causes widespread damage to blood vessels and nerves, which can result in blindness, kidney failure, or heart attack.

Case Scenario

Upon questioning the mother, the physician learned that Mrs. Morgan had a history of delivering big babies and having sugar problems during pregnancy. Mrs. Morgan probably had developed gestational diabetes. The fetus of a mother with gestational diabetes oversecretes insulin. When the neonate is born, fetal hyperglycemia is ended. Since the fetal pancreas is accustomed to oversecretion of insulin, the neonate goes into severe hypoglycemia. This hypoglycemia is usually transient. Baby Morgan's hypoglycemia was indeed transient. As revealed by capillary blood glucose monitoring several times a day for 3 days, his glucose levels returned to the normal reference range for his age group. As the effects of maternal hyperglycemia dissipated, the neonatal pancreas responded properly to Baby Morgan's first nutrients. Mrs. Morgan was referred to the diabetes educator for nutritional counseling and exercise classes to control her weight. She also received information about gestational diabetes,...

Physical Exercise

Physical Benefits Exercise Cardiac

This occurs as a result of smoking,hyperglycemia,hyperlipidemia, and hypertension. It can be improved by intensive physical exercise not only in normoglycemic patients but also in patients with diabetes melli-tus and coronary artery disease.6,9 In diabetics, however, this effect is not yet found after 4 weeks but only after a prolonged training period of 6 months. This delayed improvement in diabetic patients, as compared to normoglycemic patients, may be due to the rather diffuse atherosclerotic process that occurs in diabetes throughout the coronary tree with little normally functioning endothelium left to release nitric oxide (NO) and to react with a vasodilatory stimulus such as acetylcholine (Figure 18-2).

Sources of insulin

Insulin is synthesised and stored (bound to zinc) in granules in the p-islet cells of the pancreas. Daily secretion amounts to 30-40 units, which is about 25 of total pancreatic insulin content. The principal factor that evokes insulin secretion is a high blood glucose concentration.

Diet Alcohol

Further lowers nutrient absorption from foods. The liver is particularly vulnerable to alcohol - more than three drinks a day causes inflammation and accumulation of fat in the liver. This impairs liver function, reducing the ability to detoxify chemicals and drugs. Because the liver is important for blood sugar control, alcohol-induced liver damage can produce hypoglycemia, leading to fatigue, irritability, and concentration difficulties. Alcohol increases urinary losses of many minerals, including zinc, calcium, and magnesium.5 Because of these effects, a diet rich in fresh fruits and vegetables, whole grains, lean meats, and low-fat milk products should be carefully chosen.

Glucose Homeostasis

Following a meal (absorptive state), plasma glucose levels rise and promote hepatic glucose uptake. Elevated glucose levels stimulate the release and production of insulin by the beta-cell, which acts as a glucose sensor. Meaningfully, hepatic glucose production is suppressed by increased plasma insulin concentrations. Peripheral glucose uptake, mostly in the muscle, is also stimulated by insulin. In this way, hyperglycemia is minimized and the return of mealtime glycemic levels to pre-meal values is ensured 4 .

Phase 3 Study

In a subgroup analysis, adverse events were reported to be similar in patients younger than 65 years (n 392) compared with those who were at least 65 years of age (n 62). In this analysis, however, patients who were at least 65 years old experienced notably fewer adverse events in the nab-paclitaxel group compared with those treated with solvent-based paclitaxel (Table 2). Neutropenia, leucopenia, nausea, hyperglycemia, and flushing were all reported to be more frequent in the solvent-based paclitaxel treated patients, but statistical significance was not reported. These results suggest no additional safety concerns for nab-paclitaxel treated women at least 65 years of age compared with younger women. Hyperglycemia

Llactic Acidosis

Blood Diffusion Acidosis

Thiamin deficiency Thiamin (vitamin B1) de ficiency is a specific example of type B L-lactic acidosis that merits emphasis. Thia-min is an essential cofactor of the PDH complex, an enzyme required for the regeneration of ATP from glucose 2, 127 . A special circumstance where the effect of thiamin deficiency can be very acute occurs when keto-acids were the main brain fuel (alc oholic ketoacidosis), but ketoacids disappeared when insulin levels rise (restoration of ECF volume, especially if hyperglycemia is also present). The target organ for a deficit of thiamin is the brain for two reasons first, the brain is dependent on glucose as its energy fuel, and therefore flux through the PDH must occur in order to have ATP regeneration (unless ketoacids are present) second, there are very high rates of ATP turnover in certain areas of the brain. Hence, one can anticipate two hazards from a deficiency of thiamin, a local deficit of ATP, and a consequent local H+ accumuiation in an organ with...


Autonomic Instability

Excellent oral absorption, rapid onset of action, and short duration of effect. The magnitude of diuresis produced by the compound is similar to that seen with furosemide and ethacrynic acid. The renal sites of action are interpreted to be the proximal tubule and the ascending limb of Henle (254,255). Interestingly, a study of rats and dogs indicated that triflocin has no propensity for evoking hyperglycemia (256).The drug was studied in normal volunteers and found to be a markedly potent natriuretic agent free water clearance (CH5 0) was inhibited during water diuresis and solute-free water reabsorption (TCHzQ) reduced hydropenia, indicating a major site of action in the ascending limb of Henle. In addition a fall in the glomerular filtration rate of 10-15 was found at doses of 1 g given orally (257) .Long-term toxicity studies revealed adverse effects clinical studies were therefore discontinued (258).In rats, doses of 100 and 200 mg kg-' day'1 caused no adverse effects (259).Doses...

Clinical Approach

Hyponatremia associated with a hyposmolar state is more common and more dangerous. Some hyponatremic conditions are associated with hyperos-molarity or with normal osmolarity. Hyperosmolar hyponatremia is most often caused by an increase in the serum level of an osmotically active molecule that is confined to the extracellular space and that cannot readily cross cell membranes, such as glucose or mannitol. These solutes draw water out from the intracellular space, leading to relative hyponatremia. Hyperglycemia occurs in the setting of insulin-deficient states, such as uncontrolled diabetes mellitus. For glucose, each 100 mg dL increase in serum glucose leads to an approximately 1.6 mmol L decrease in the serum sodium level. Transurethral

Diabetes Mellitus

Diabetes is a family of disorders that is characterized by hyperglycemia. The disorders of diabetes differ in their etiology and symptoms and in the consequences of disease. The American Diabetes Association (ADA) estimates that approximately 7 of the population of America suffers from diabetes. Therefore, it is a serious public health threat and economic burden on health care funds.1-3 Type 1 diabetes is characterized by lack of insulin production and secretion by the beta cells of the pancreas. One cause of the hyperglycemia of type 1 diabetes mel-litus is an autoimmune destruction of the beta cells of the pancreas. The cellmediated response causes infiltration of the pancreas and reduction in the volume of beta cells. As a protein hormone, insulin acts through chemical responses to receptors on the cells of target tissues. In the muscle, insulin stimulates glucose uptake into cells and enhances glycogenesis. In adipose tissue, insulin stimulates glucose uptake into cells and...
