Recent studies indicate that stress induces increased food intake only when stress is followed by a neuroendocrine reaction with increased cortisol concentrations. The stress of modern society may contribute to the current epidemic of abdominal obesity, which is characterised by increases in cortisol and leptin concentrations. This is a condition which carries a great risk for cardiovascular disease, type 2 diabetes mellitus and stroke.

Several issues should be addressed when managing women with Turner's syndrome. Female sex hormone substitution should be offered to help prevent the increased morbidity seen in Turner's women, which consists of an increased risk of fractures and osteoporosis, and a clustering of diseases such as ischaemic heart disease, hypertension, stroke and type 2 diabetes, the latter entities being part of the insulin resistance syndrome. Furthermore, hypothyroidism is often seen, and the risk of type 1 diabetes may also be increased. Congenital malformations of the heart are frequently seen in Turner's syndrome, possibly increasing the risk of dissecting aorta aneurysm. Liver enzymes are often elevated and there may be an increased risk of liver cirrhosis. Mortality seems to be increased in Turner's syndrome, women with the "pure" 45,X karyotype being the most severely affected. In clinical practice, careful monitoring of glucose and bone metabolism, weight, thyroid function and blood pressure should be carried out. A cardiovascular risk profile should be determined and the patient informed of the risks and benefits of sex hormone replacement therapy. Sex hormone replacement therapy is highly recommended, although at present there are no longitudinal data documenting the long-term positive effect of sex steroid substitution. However, hypogonadism is expected to explain at least part of the decreased lifespan found in Turner's syndrome. Since general physicians only encounter these patients infrequently, it is recommended that the care and treatment of Turner's syndrome be centralized.

Major clinical trials have shown that excellent glycemic control, sustained over time, can prevent or delay the microvascular complications of diabetes, including retinopathy, nephropathy, and neuropathy. No prospective trial has clearly shown that glycemic intervention can prevent the macrovascular complications of diabetes, such as myocardial infarction, cerebrovascular accident, and amputation. However, a number of landmark clinical trials have shown the efficacy of control of blood pressure and lipids and use of antiplatelet agents (mainly aspirin) in protecting the macrovasculature of individuals with diabetes. In this article, glycemic, blood pressure, lipid, and antiplatelet trials relevant to the treatment of people with type 2 diabetes are reviewed.

Type 2 diabetes mellitus and impaired glucose tolerance are associated with antipsychotic treatment. Risk factors for type 2 diabetes and impaired glucose tolerance include abdominal adiposity, age, ethnic status, and certain neuropsychiatric conditions. While impaired glucose metabolism was first described in psychotic patients prior to the introduction of antipsychotic medications, treatment with antipsychotic medications is associated with impaired glucose metabolism, exacerbation of existing type 1 and 2 diabetes, new-onset type 2 diabetes mellitus, and diabetic ketoacidosis, a severe and potentially fatal metabolic complication. The strength of the association between antipsychotics and diabetes varies across individual medications, with the largest number of reports for chlorpromazine, clozapine, and olanzapine. Recent controlled studies suggest that antipsychotics can impair glucose regulation by decreasing insulin action, although effects on insulin secretion are not ruled out. Antipsychotic medications induce weight gain, and the potential for weight gain varies across individual agents with larger effects observed again for agents like chlorpromazine, clozapine, and olanzapine. Increased abdominal adiposity may explain some treatment-related changes in glucose metabolism. However, case reports and recent controlled studies suggest that clozapine and olanzapine treatment may also be associated with adverse effects on glucose metabolism independent of adiposity. Dyslipidemia is a feature of type 2 diabetes, and antipsychotics such as clozapine and olanzapine have also been associated with hypertriglyceridemia, with agents such as haloperidol, risperidone, and ziprasidone associated with reductions in plasma triglycerides. Diabetes mellitus is associated with increased morbidity and mortality due to both acute (e.g., diabetic ketoacidosis) and long-term (e.g., cardiovascular disease) complications. A progressive relationship between plasma glucose levels and cardiovascular risk (e.g., myocardial infarction, stroke) begins at glucose levels that are well below diabetic or "impaired" thresholds. Increased adiposity and dyslipidemia are additional, independent risk factors for cardiovascular morbidity and mortality. Patients with schizophrenia suffer increased mortality due to cardiovascular disease, with presumed contributions from a number of modifiable risk factors (e.g., smoking, sedentary lifestyle, poor diet, obesity, hyperglycemia, and dyslipidemia). Patients taking antipsychotic medications should undergo regular monitoring of weight and plasma glucose and lipid levels, so that clinicians can individualize treatment decisions and reduce iatrogenic contributions to morbidity and mortality.

Patients with type 2 diabetes have a two- to four-fold greater risk of cardiovascular mortality than non-diabetic individuals. In order to prevent coronary events in the diabetic population, it is important to treat modifiable cardiovascular risk factors. Data from the Multiple Risk Factor Intervention Trial (MRFIT) show that serum cholesterol level, systolic blood pressure level and cigarette smoking were significant predictors of cardiovascular disease mortality in men with and without diabetes. At every risk factor level, the absolute risk of age-adjusted coronary death rate was three times greater for diabetic men than non-diabetic men (p<0.0001). Patients with diabetes have an abnormal (dyslipidaemic) lipoprotein profile with high levels of very low density lipoprotein cholesterol and triglycerides, and a low level of high density lipoprotein cholesterol. Although levels of total cholesterol or low density lipoprotein (LDL) cholesterol do not differ significantly between patients with and without diabetes, those with diabetes have higher levels of atherogenic small dense LDL particles. MRFIT data show that at any serum cholesterol level, diabetes confers two-three times the risk for a coronary event. These findings constitute the rationale for considering hypolipaemic therapy, e.g. with HMG-CoA reductase inhibitors (statins), in diabetic patients with dyslipidaemia, particularly in those with evidence of coronary heart disease. Evidence shows that statins significantly lower cholesterol, exhibit beneficial effects on many components of atherosclerosis, and can significantly reduce the incidence of stroke.

If a strong association between intima-media thickness of the common carotid artery (CCA-IMT) and ischemic stroke can be determined in diabetic subjects, it may be a useful predictor to help identify patients at high risk of ischemic stroke. To investigate the relative contribution of CCA-IMT to ischemic stroke in patients with type 2 diabetes, we measured CCA-IMT and other conventional risk factors in 438 Japanese patients with type 2 diabetes, including 45 with ischemic stroke and 393 controls. Stroke patients were characteristically and significantly older with higher body mass index, longer duration of diabetes, likely to be smokers, higher blood pressure, and higher total cholesterol compared with the controls. CCA-IMT in stroke patients (1.23 +/- 0.04 mm) was significantly greater than in control patients (0.95 +/- 0.01 mm, P <.01). CCA-IMT in stroke patients was still significantly greater than controls after adjustment for age, sex, body mass index, and smoking status (P <.05). A 0.1-mm increase in CCA-IMT was associated with 1.80-fold increase in the odds ratio of stroke in diabetic patients (95%confidence interval [CI], 1.49 to 2.17; P <.01). Four independent factors were found to correlate significantly with CCA-IMT: age, systolic blood pressure, HbA(1c), and high-density lipoprotein (HDL) cholesterol. Thus, thickening of the intima-media of common carotid arteries is associated with ischemic stroke in type 2 diabetic patients. To prevent ischemic stroke, strict control of diabetes, hypertension, and dyslipidemia and monitoring of CCA-IMT may be important.

In this study, prevalence and incidence of complications as well as co-morbidity in type 2 diabetes patients in Germany were evaluated as part of a cost-of-illness study (CODE-2(TM), Costs of Diabetes in Europe - Type 2)In a pre-study, 197 general practitioners and diabetes specialists all over Germany provided data on the complication status of 2701 randomly selected patients with type 2 diabetes. The patients were grouped into five mutually exclusive strata. This pre-study was performed to generate a general overview on complication status to select proper patients for the main study. The main study was performed on stratified samples derived from the pre-study. Irrespective of the real prevalence of the five strata, an equal number of 160 were randomly selected from each stratum. Thus, rare complications were also covered in the study. Data from 809 patients were collected retrospectively on the basis of medical files during interviews with the physician. To achieve representative estimates of absolute prevalence and incidence of diabetes-related complications in Germany, results were weighted using frequencies of the strata. Severe complications were diagnosed in 50% of these patients. Prevalences were: 10.56% myocardial infarction, 6.66% stroke, 3.97% foot ulcer, 2.30% amputations and 1.34% blindness. Overall incidences in the diabetes population were estimated at 0.78% myocardial infarction, 1.28% stroke and 0.80% amputations. 23% of the diabetes patients suffered from 2 or more complications. The complication status became considerably worse with increasing time since the diagnosis of diabetes. The mean HbA1c level was 7.51% (i.e. 122% of the upper limit of the respective normal ranges). The presence of complications and co-morbidity in type 2 diabetes patients was a frequent finding. This underlines the importance of complications in diabetes patients and the necessity to increase any means of prevention in order to relieve the personal and economic burden of type 2 diabetes.

There is an age-related increase in total body fat and visceral adiposity until age 65 years that often is accompanied by diabetes or impaired glucose tolerance. The prevalence of type 2 diabetes increases progressively with age, peaking at 16.5% in men and 12.8% in women at age 75-84 years. Over age 65, diabetes or glucose intolerance was present in 30%-40% of Framingham Study subjects. There has been an alarming increase, of epidemic proportions, in both obesity and diabetes in the general population. Type 2 diabetes and obesity are both associated with a clustering of atherogenic risk factors, and when three or more are present it generally signifies an insulin resistance syndrome. This is promoted by weight gain and visceral adiposity. The risk of macrovascular disease is increased before glucose levels reach the diagnostic threshold for "diabetes," and 25% of newly diagnosed diabetics already have overt cardiovascular disease. In the Framingham Study, increased risk of cardiovascular disease was two-fold in men and three-fold in women, eliminating the female advantage over men for all outcomes except stroke. Coronary disease is the most common and lethal sequela, and unrecognized myocardial infarctions are three times more common in diabetic than nondiabetic men. Following a myocardial infarction, diabetes imposes a high rate of recurrence, heart failure, and death, more so in women than men. The risk of cardiovascular sequelae in diabetics is variable, the majority of events occurring in those with two or more additional risk factors. Because of the variable risk of cardiovascular disease in either the diabetic or obese person, risk stratification is necessary to determine the hazard of impending cardiovascular disease. This is readily accomplished with Framingham cardiovascular risk formulations. For persons with diabetes or obesity, the chief goal is to avoid the common cardiovascular sequelae. Comprehensive care should include not only normalization of the blood sugar, but also weight reduction, dietary fat restriction, strict blood pressure and lipid control, exercise, and avoidance of tobacco. Trial data indicate that preventive measures benefit obese diabetics even more than nondiabetics.

Glycogen synthase kinase 3 (GSK-3) is a serine/threonine protein kinase that has recently emerged as a key target in drug discovery. It has been implicated in multiple cellular processes and linked with the pathogenesis of several diseases. GSK-3 inhibitors might prove useful as therapeutic compounds in the treatment of conditions associated with elevated levels of enzyme activity, such as type 2 diabetes and Alzheimer's disease. The pro-apoptotic feature of GSK-3 activity suggests a potential role for its inhibitors in protection against neuronal cell death, and in the treatment of traumatic head injury and stroke. Finally, selective inhibitors of GSK-3 could mimic the action of mood stabilizers such as lithium and valproic acid and be used in the treatment of bipolar mood disorders.

Last year, in 2001, the results of several major clinical trials have been published, concerning hypertensive patients with type 2 diabetes (IRMA, RENAAL and IDNT studies) and patients with previous strokes. Angiotensin II antagonists (irbesartan and losartan) are able to reduce the rate of progression of diabetic nephropathy in hypertensive patients with type 2 diabetes. This preventive effect occurs independently of the stage of renal dysfunction (early stage in IRMA, patent nephropathy in RENAAL and advanced nephropathy in IDNT). The PROGRESS study shows that the decrease in blood pressure, in response to an ACE inhibitor/diuretic bitherapy (perindopril/indapamide), in patients with previous minor stroke or transient ischaemic attack, reduces significantly the risk of recurrent stroke.
