In vitro studies have shown a two-stage process proliferation followed by differentiation menstruation thesaurus generic anastrozole 1mg line. The proliferative phase is initiated by hormonal stimulation with insulin and glucocorticoids pregnancy varicose veins buy 1mg anastrozole free shipping. After the cells begin to grow they enter a state of differentiation where they acquire the genetic state of mature fat cells that can store fatty acids breast cancer gifts order anastrozole 1 mg, break down triglycerides breast cancer stage 0 grade 3 buy 1mg anastrozole amex, and make and release the many hormones that characterize the mature fat cell women's health center university of arizona purchase anastrozole 1mg on-line. Most of the fatty acids that are stored in human fat cells are derived from the diet womens health partners summerville sc buy anastrozole 1mg line, although these cells maintain the capacity for de novo synthesis of fatty acids [72]. The discovery of leptin catapulted the fat cell into the arena of endocrine cells [73]. The finding of a peptide released from adipose tissue that acts at a distance has refocused interest in the fat cell from primarily a cell that stores fatty acids to a cell with endocrine and paracrine functions. Messages to the brain from the environment and from the body the brain receives a continuous stream of information from both the external and internal environments that have a role in the control of feeding. The external information provided by sight, sound and smell are all distant signals for identifying food. Taste and texture of foods are proximate signals generated when food enters the mouth. The classic tastes are sweet, sour, bitter and salty as well as "umami," a fifth taste. In nature most "sweet" foods also have vitamins and minerals, because they come from fruits. The extreme example of this is "bait shyness" or "taste aversion," the property that some items have that produces a permanent rejection of future food with the same taste. This is a "hard-wired" response in the brain that overrides the usual "feedback" signals. The discovery of taste and smell receptors for polyunsaturated fatty acids on the taste bud that involves a potassium rectifier channel offers an opening into modifying taste inputs into the food-intake system [74]. When this receptor is activated, there is a rise in pancreatic secretions and an increase in their content [75]. Several gastrointestinal peptides have been studied as potential regulators of food intake. Investigation of the growth hormone secretagogue receptor has led to the identification of a new gastrointestinal hormone involved with the control of feeding. It is a 28 amino acid peptide with an n-octanoyl residue on the serine in the 3-position. The level is low in overweight people, suggesting that it may have a role in controlling appetite and weight gain [7880]. Amylin is produced in the beta cell of the pancreas along with insulin and is co-secreted. In experimental studies, amylin has been shown to reduce food intake by acting on the amylin (calcitonin-like gene product) receptor. The major locations for this receptor are in the hind-brain and hypothalamus [81]. Pramlintide is a commercial analog of amylin which is currently used to treat diabetes. A dip in the circulating level of glucose precedes the onset of eating in more than 50% of the meals in animals and human beings [82]. The pattern recognized by this dip is independent of the level from which the drop in glucose begins. The dip follows a small rise in insulin, suggesting a relationship of these two signals [1,77]. The brain and food intake the brain plays the central role as receiver, transducer and transmitter of information from the peripheral organs [83]. This control is accomplished through sensory organs and internal signals that are integrated through central neurotransmitters that in turn activate neural, hormonal and motor efferent pathways. Weight gain and overeating were common side effects of frontal leucotomy performed in the mid-1900s for psychosis. Damage to the right frontal lobe can cause the gourmand syndrome, a passion for eating and a specific preference for fine food. Hyperphagia correlates positively with right frontal atrophy and negatively with left frontal atrophy in degenerative dementia. Monoamines, such as norepinephrine, serotonin, dopamine and histamine, as well as certain amino acids and neuropeptides, are involved in the regulation of food intake. The serotonin system has been one of the most extensively studied of the monoamine pathways [1,77]. Its receptors modulate both the quantity of food eaten and macronutrient selection. Stimulation of the serotonin receptors in the paraventricular nucleus reduces fat intake with little or no effect on the intake of protein or carbohydrate. Phenylpropanolamine is an agonist acting on this receptor that has a modest inhibition of food intake. Some of the antagonists to the 1 receptors that are used to treat hypertension produce weight gain, indicating that this receptor is also clinically important. Stimulation of 2 receptors increases food intake in experimental animals, and a polymorphism in the 2a-adrenoceptor has been associated with reduced metabolic rate in humans. These receptors can be activated by agonist drugs (betablockers), by releasing norepinephrine in the vicinity of these receptors, or by blocking the reuptake of norepinephrine. Experimentally this has been utilized by modulating the H3 autoreceptor, which controls histamine release. When the autoreceptor is stimulated, histamine secretion is reduced and food intake increases. The histamine system is important in control of feeding because drugs that modulate histamine receptors may produce weight gain. In animals, seasonally variable dopamine transmission in the suprachiasmatic nucleus appears to drive the storage of food at the appropriate time of year in anticipation of hibernation or migration. Loss-of-function mutations in the D2 receptor gene are associated with overweight in human beings, and dopamine antagonists can induce obesity in humans. One suggestion is that this is through modulation of nutrient partitioning, with obesity in humans or fat storage in migratory and hibernating species as the results [85]. The opioid receptors were the first group of peptide receptors shown to modulate feeding. Stimulation of the mu-opioid receptors increases the intake of dietary fat in experimental animals. The endocannabinoid system is a most recent addition to the central controllers of feeding [87]. Isolation of the cannabinoid receptor was followed by identification of two fatty acids, anandamide and 2-arachidonoylglycerol, which are endogenous ligands in the brain for this receptor. Infusion of anandamide or 2-arachidonoylglycerol into the brain stimulates food intake. Antagonists to this receptor have been shown to reduce food intake and lead to weight loss. The discovery of leptin in 1994 opened a new window on the control of food intake and body weight [1,77,88]. This peptide is produced primarily in adipose tissue, but can also be produced in the placenta and stomach. As a placental hormone it can be used as an indicator of trophoblastic activity in patients with trophoblastic tumors (hydatidiform moles or choriocarcinoma). Leptin is secreted into the circulation and acts on a number of tissues, with the brain being one of its most important targets. The response of leptin-deficient children to leptin indicates the critical role that this peptide has in the control of energy balance. To act on leptin receptors in the brain, leptin must enter brain tissue, probably by transport across the bloodbrain barrier [86]. Leptin acts on receptors in the arcuate nucleus near the base of the brain to regulate, in a reciprocal fashion, the production and release of at least four peptides. It produces these effects through interaction with either the Y-1 or the Y-5 receptor. When 133 Part 2 Normal Physiology these receptors are knocked out by genetic engineering, the mice become grossly overweight. In recent human studies, genetic defects in the melanocortin receptors are associated with significant excess of body weight. Some of these genetic changes profoundly affect feeding, whereas others have little or no effect. Antagonists to these peptides or drugs that prevent them from being degraded would make sense as potential treatment strategies. Two other peptide systems with neurons located in the lateral hypothalamus in the brain have also been linked to the control of feeding. This peptide increases food intake when injected into the ventricular system of the brain. Animals that overexpress this peptide gain weight and animals that cannot produce this peptide are lean. This peptide was identified in a search of G-protein linked peptides that affect food intake. It increases food intake, but its effects are less robust than those described above. The first of these peptides to be isolated from a mollusk had only four amino acids. This family of peptides has been involved in feeding from early phylogetic times including Caenorhabdis elegans. Testosterone levels fall as human males grow older, and there is a corresponding increase in visceral and total body fat and a decrease in lean body mass in older men. This may be compounded by the decline in growth hormone that is also associated with an increase in fat relative to lean mass, particularly visceral fat. One recent finding suggests that the activity of the enzyme 11-hydroxysteroid dehydrogenase type 1, which reversibly converts cortisone to cortisol, may be important in determining the quantity of visceral adipose tissue. Changes in this enzyme may contribute to the risk of women of developing more visceral fat after menopause. A high level of this enzyme keeps the quantity of cortisol in visceral fat high and provides a fertile ground for developing new fat cells. The sympathetic nervous system is an important link between the brain and peripheral metabolism. It appears to be involved in the oscillation of fatty acids in visceral fat that accompanies the increased fat as dogs overeat a high-fat diet [93]. Using genetic homologous recombination (knockout) mice lacking the 1, 2 and 3 receptor have been produced. Thus sympathetic nervous system function is essential to prevent obesity and to resist cold [9496]. Conclusions this chapter aims to provide a snapshot of our understanding of the regulatory systems for factors that are etiologic in obesity. Both epidemiologic and metabolic feedback models are reviewed in assembling this information. It is clear, however, that we have a much better glimpse into its operation one that can provide us a better framework for thinking about both the etiology of obesity and its possible treatments. Neural and hormonal control of metabolism the motor system for acquisition of food and the endocrine and autonomic nervous systems provide the major information for control of the major efferent systems involved with acquiring food and regulating body fat stores. Among the endocrine controls are growth hormone, thyroid hormone, gonadal steroids (testosterone and estrogens), glucocorticoids and insulin. During growth, growth hormone and thyroid hormone work together to increase the growth of the body. At puberty, gonadal steroids enter the picture and lead to shifts in the relationship of body fat to lean body mass in boys and girls.

Another new class of drugs women's health clinic omaha ne purchase anastrozole 1mg online, acting on the incretin system, were introduced in 2005. Tolbutamide, phenformin and insulin were compared in the treatment of maturity-onset diabetes in the first randomized controlled trial, the University Group Diabetes Program [7375]. This much-criticized study concluded that the death rate was higher for both oral agents than for placebo, and that insulin (whether given in a fixed or variable dose) was no better than placebo [75]. Long-acting insulins were welcomed by diabetes specialists and patients, but their use as a single daily injection probably produced worse glycemic control than three or four injections of soluble insulin. Indeed, delayed-action preparations were initially condemned by some diabetes specialists, such as Russell Wilder of the Mayo Clinic, because the patient could slip without apparent warning into hypoglycemia. The number and variety of insulin preparations proliferated, but the main advances were in methods to produce highly purified preparations from porcine or bovine pancreas, which remained the source for therapeutic insulin until the early 1980s. From there, genetic engineering has been used to produce "designer" insulins such as the fast-acting insulin analogs lispro and aspart and the "peakless" basal insulins such as glargine and detemir. How much these will improve glycemic control in the generality of people with diabetes is debatable; weekend golfers do not become champions when given expensive clubs! Patients and manufacturers hope that there will eventually be an Glucose control and treatment targets During the 1920s, opinion leaders advocated normalizing blood glucose in young patients with diabetes, the rationale being to "rest" the pancreas, in the hope that it might regenerate. The only way of monitoring diabetic control was by testing the urine for glucose, and attempts to keep the urine free from sugar inevitably resulted in severe hypoglycemia and often psychologic damage. This led to the so-called "free diet" movement linked particularly with Adolf Lichtenstein (Stockholm) and Edward Tolstoi (New York) which encouraged patients to eat whatever they liked and not to worry about glycosuria, however heavy. Only one-third of diabetes physicians questioned in England in 1953 thought that normoglycemia would prevent diabetic complications, and only one-half advised urine testing at home [77]. Practical monitoring of diabetic control became feasible in the late 1970s with the introduction into clinical practice of test strips for measuring blood glucose in a fingerprick sample and the demonstration that ordinary patients could use them at home [78,79]. These methods in turn made possible the North American Diabetes Control and Complications Trial, which in 1993 finally established that good control prevents and delays the progression of microvascular complications in type 1 diabetes [81]. By the late 1990s it was clear that reducing glucose levels, high blood pressure or cholesterol separately would reduce the frequency of heart disease and death and it was natural to wonder whether tackling them simultaneously (multiple risk factor intervention) would be even better. The Steno 2 study, which began in Denmark in 1992, enrolled patients with type 2 diabetes with microalbuminuria and after 13 years of follow-up showed that multiple risk factor intervention reduced the risk of death by 20% and the risk of developing nephropathy, retinopathy and neuropathy by 50% [84]. Diabetic complications Apart from the general benefits of controlling blood glucose, some specific treatments have emerged for certain chronic complications. Well-conducted clinical trials during the late 1970s showed the effectiveness of laser photocoagulation in preventing visual loss from both maculopathy and proliferative retinopathy [85]. This technique was derived from the xenon arc lamp originally described in the late 1950s by Gerd Meyer-Schwickerath (192192) of Essen, Germany [86]. The importance of blood pressure control in preventing the progression of nephropathy is now fully recognized, and angiotensin-converting enzyme inhibitors may be particularly beneficial; that blood pressure control slowed the progression of nephropathy was shown in studies by Carl-Erik Mogensen (b. Diabetic ketoacidosis the introduction of insulin was only one aspect of the management of this acute and previously fatal complication of diabetes. Of the first 33 cases treated by Joslin and his colleagues between January 1, 1923 and April 1, 1925, 31 survived an excellent outcome, even by modern standards, which Joslin [89] attributed to: "Promptly applied medical care, rest in bed, special nursing attendance, warmth, evacuation of the bowels by enema, the introduction of liquids into the body, lavage of the stomach, cardiac stimulants, and above all the exclusion of alkalis. In 1933, the death rate from ketoacidosis in Boston was only 5%, but elsewhere in North America and Europe it averaged 30% and could be as high as 75%. An important advance in management was the acceptance of relatively low-dose insulin replacement, following the example of Ruth Menzel and colleagues in Karlsburg, Germany [90]. Another step forward was the recognition by Jacob Holler in 1946 of the danger of hypokalemia [92]. Delivery of care for people with diabetes From the earliest days of insulin injection and urine testing, it was apparent that people with diabetes needed knowledge and practical skills to manage their disease effectively. Lip-service was often paid to the importance of diabetes education, but most patients were badly informed. In 1952, Samuel Beaser (1910 2005) questioned 128 patients attending the Boston Diabetes Fair, and found that "all were distinctly deficient in knowledge of their disease" [95]; he felt that responsibility lay with both doctors and administrators. Further studies during the 1960s by Donnell Etzwiler (19272003) in Minneapolis showed that many doctors and nurses were also ignorant about managing diabetes. Since the Diabetic pregnancy As late as 1950, the outcome of pregnancy in women with diabetes was still very poor in most units, with perinatal fetal losses of 4565%, some 10 times higher than in the general population. Exceptions to this depressing rule were the units run by Priscilla White at the Joslin Clinic in Boston, who had published excellent results as early as 1935 [93], and by Jшrgen Pedersen in Copenhagen (Figure 1.

In the symptomatic person a single abnormal value, either casual or fasting, is often enough to confirm the diagnosis. In asymptomatic individuals two abnormal values are required and an oral glucose tolerance test may be needed · the diagnosis of diabetes can not be excluded by measuring fasting plasma glucose alone · HbA1c has major advantages over glucose testing in terms of convenience and lack of variability, although it is not adequately quality assured or standardized in many places, and is costly. Nonetheless, it is already recommended in some countries as an alternative diagnostic test. This is likely to become more widespread Introduction Diabetes mellitus is a disease of antiquity (see Chapter 1). A treatment was described in the Ebers papyrus and as long ago as 600 bc two main types were distinguished. Perhaps the most famous description was by Arateus the Cappadocian who talked of the melting down of flesh into urine and of the end being speedy. Over the ensuing centuries sporadic descriptions were noted, with Maimonides in Egypt pointing out its relative rarity. It was attributed to a salt-losing state although the sweetness of the urine had long been known. Diabetes was better recognized in the 17th and 18th centuries, with the association with obesity noted in some cases. The obvious breakthrough came in the 17th century with the demonstration of excess glucose in the urine and later also in blood. A clear description of the two main types of diabetes appeared at the end of the 19th century, with the distinction being made between that occurring in young people with a short time course before ketoacidosis supervened, and that found in older people who were obese. Over the next decades these became known as juvenile-onset diabetes and maturity-onset diabetes, although it Textbook of Diabetes, 4th edition. Diagnosis now depended on glucose measurement with some using glucose tolerance tests. There were no standard criteria for these initially, although glucose levels were clearly above normal. Diagnosis usually occurred after clinical development of the disease with the combination of symptoms with raised glucose in the blood or glycosuria being diagnostic, together with ketonuria in the juvenile-onset form. The next milestone was the development of the radioimmunoassay for insulin which allowed the unequivocal demonstration of insulin deficiency, or indeed absence, in those with juvenile-onset diabetes while levels were apparently normal or raised in those with maturity-onset diabetes. At that time, diabetes was still considered to be a relatively uncommon disorder occurring predominantly in Europids. These events form the starting point for the diagnostic criteria and classification used today. It is characterized by chronic hyperglycemia together with disturbances of carbohydrate, fat and protein metabolism resulting from defects of insulin secretion, insulin action or both [6]. These are associated with the development of the specific microvascular complications of retinopathy, which can lead to blindness, nephropathy with potential renal failure, and neuropathy. The latter carries the risk of foot ulcers and amputation and also autonomic nerve dysfunction. The characteristic clinical presentation is with thirst, polyuria, blurring of vision and weight loss. Often, symptoms are mild or absent and mild hyperglycemia can persist for years with tissue damage developing, although the person may be totally asymptomatic. Type 1 diabetes (-cell destruction) · Autoimmune · Idiopathic Type 2 diabetes (insulin resistance with insulin hyposecretion) Other specific types (Table 2. Classification There was awareness of different grades of severity of diabetes for many centuries; however, the possibility that there were two distinct types only emerged at the beginning of the 20th century. There were many other phenotypes in vogue at that time including brittle, gestational, pancreatic, endocrine, insulin-resistant and iatrogenic diabetes, but for most cases there was no clear indication of etiology. This gave a clear indication that younger patients with diabetes, all of whom required insulin therapy, had an autoimmune disorder. Malnutrition-related diabetes mellitus was also introduced in recognition of a different phenotype found particularly in Asia and sub-Saharan Africa. The new classification attempted to encompass both etiology and clinical stages of the disease as well as being useful clinically. As with autoimmune diabetes, however, there is clear loss of -cell function as measured by low or absent C-peptide secretion. Typically, they do not require insulin to survive but often will eventually need insulin to maintain reasonable glycemia control, often after many years. Major efforts have been made to discover underlying genetic abnormalities but with only modest success (see Chapter 12). Both obesity, particularly visceral adiposity, and physical inactivity cause insulin resistance which will result in diabetes in those with only a small capacity to increase insulin secretion. Thus, those of Polynesian, Micronesian, South Asian, sub-Saharan African, Arabian and Native American origin are much more prone to develop diabetes than Europids. Other specific types of diabetes Diabetes occurs both as a result of specific genetic defects in insulin secretion and action and in a range of other conditions (Table 2. These account for a small number of people with diabetes but are important in determining therapeutic approaches. The association of diabetes with defects in insulin action has long been known, particularly in type A insulin resistance, leprechaunism and lipoatrophic diabetes. Not surprisingly, diseases of the exocrine pancreas often cause diabetes through destruction of the islets. Pancreatitis secondary to alcohol is probably the most common of these (see Chapter 18). Originally, this was part of malnutrition-related diabetes mellitus where there were two proposed variants: one associated with cassava consumption in malnourished people but without evidence of calculi, while the other was found after tropical pancreatitis and presented with fibrocalculous disease. The latter is akin to the diabetes found with other forms of chronic pancreatitis. In 1999 it was felt that this latter form would fit into the category of "other specific types" and that more evidence was needed before a specific malnutrition-related diabetes category could be included.
