Diabetes, known since antiquity, has been defined by glycosuria. In 1886, when Minkowski demonstrated that pancreatectomized dogs developed diabetes, the islets of Langerhans became a focus of the search for an active principle culminating in the discovery and the isolation of insulin in 1921 by Banting, Best and Collip. In 1959, the radioimmunoassay of Yalow and Berson solidified the concept of insulin resistance in non-insulin dependent diabetes (NIDDM). In 1971, the insulin receptor was defined as a cell surface protein that initiated the insulin signal transduction cascade. Today, we know that NIDDM accounts for at least 90% of all diabetes worldwide and involves approximately 100 million people. The microvascular complications of NIDDM are the same as for insulin dependent diabetes (IDDM) and are related to the intensity and duration of hyperglycaemia. Further, it is clear from the Diabetes Control and Complications Trial (DCCT) that all microvascular complications can be reduced with intensive control of the blood glucose. Macrovascular disease is also accelerated in NIDDM, including both hypertension and dyslipidemia. The major risk factor for NIDDM are age, obesity, physical inactivity, and genetic background. The earliest features seen in individuals destined to develop NIDDM is insulin resistance, but for hyperglycaemia to ensure there must be a defect in insulin secretion. Thus, insulin resistance defines the prehyperglycaemic phase of NIDDM, but varying degrees of insulin secretory deficiency define the hyperglycaemic phase. Macrovascular risk occurs throughout the lifetime of the individual, whereas microvascular risk ensues with the inception of hyperglycaemia. Tomorrow, we will understand more clearly whether lifestyle changes, such as diet and exercise, or new classes of drugs, can delay or prevent NIDDM. Clinical trials are now beginning to test whether impaired glucose tolerance (IGT) can be delayed or prevented from moving to overt NIDDM. The genetics of NIDDM are under intense study. Mutations in the insulin receptor lead to NIDDM in a small number of patients, and mutations in the glucokinase gene lead to maturity onset diabetes of the young (MODY). Work is now underway to study other candidate genes as well as work on positional cloning techniques to identify diabetes genetic loci. The hormone Leptin has just been discovered and is a major regulator of body weight. In summary, the most important new emphasis on the treatment of NIDDM is the recognition of the importance of hyperglycaemia and our ability to both treat and possibly prevent this metabolic perturbation. This joins the longer-term emphasis on cardiovascular risk reduction from both treatment and prevention of hypertension and dyslipidemia.

Hyperuricemia (HU) is present in 5-30% of the general population, although the prevalence is higher among some ethnic groups and seems to be increasing worldwide. Classically, chronic HU has been considered a risk factor for gout or lithiasis and is associated with alcoholism, obesity, hypertension, dyslipidemia, hyperglycemia/diabetes mellitus, renal failure and intake of certain drugs. HU is also associated with cardiovascular diseases such as hypertension, vascular disease, pre-eclampsia, pulmonary arterial hypertension, stroke, heart failure, ischemic heart disease and also metabolic syndrome, renal disease and increased mortality. It is uncertain if these associations are dependent or not, especially cardiovascular and renal diseases. Patients with chronic HU and also those with gout require both medical investigation for associated diseases or drugs as well as nutritional counseling and life-style changes. HU should alert physicians to possible complications.

The prevalence of childhood obesity is increasing worldwide, as is the prevalence of obesity-related co-morbidity. Altered glucose metabolism, manifested as impaired glucose tolerance (IGT), appears early in obese children and adolescents. Obese young people with IGT are characterized by marked peripheral insulin resistance and a relative beta-cell failure. Lipid deposition in muscle and the visceral compartment, and not only adiposity per se, is related to increased peripheral insulin resistance, the "driving force" of the metabolic syndrome. Other elements of the metabolic syndrome, such as dyslipidemia and hypertension, are already present in obese youngsters and worsen with the degree of obesity. Similarly, markers of systemic "low-grade inflammation" worsen with increasing adiposity. The long-term impact on cardiovascular and liver morbidity of obesity-related insulin resistance in young people is expected to emerge as these youngsters become young adults.

Polycystic ovary syndrome (PCOS) is increasingly being recognized in adolescent girls seeking treatment for signs and symptoms of hyperandrogenism. It is difficult to diagnose PCOS in adolescents, therefore a high index of suspicion is necessary. Timely screening and treatment are crucial because another important component of the syndrome is insulin resistance/hyperinsulinemia increasing the risk for type 2 diabetes, dyslipidemia, and cardiovascular sequelae. Diagnosis of PCOS in adolescents should include a thorough family history, exclusion of other causes of hyperandrogenism, and appropriate laboratory evaluation. The scarcity of controlled clinical trials makes treatment controversial. Therapeutic options include lifestyle intervention, oral contraceptive pills, and insulin sensitizers. Long-term follow-up is needed to determine the effectiveness of these approaches in changing the natural history of the reproductive and metabolic outcomes without causing undue harm.

By the time of renal transplantation, end-stage renal disease patients have a huge burden of cardiovascular disease (CVD) and are heavily saturated with atherosclerotic risk factors. Worsening of preexisting risk factors or new CVD risk factors may develop in the posttransplant period consequent in part to the diabetogenic and atherogenic potential of immunosuppressive drugs. The annual risk of a fatal or non-fatal CVD event of 3.5 to 5% in kidney transplant recipients is 50-fold higher than the general population. Renal allograft dysfunction, proteinuria, anemia, moderate hyperhomocysteinemia and elevated serum C-reactive protein concentrations, each dependently confer greater risk of CVD morbidity and mortality in the posttransplant period. Long-term care of renal transplant recipients should programmatically incorporate the recommendations of the National Kidney Foundation Working Groups and European Best Practice Guidelines Expert Group on Renal Transplantations into the management of hypertension, dyslipidemia, smoking, and posttransplant diabetes mellitus. Timely utilization of coronary revascularization procedures should be undertaken as these treatments are equally effective in the kidney transplant population.

Patients with type-2 diabetes mellitus (T2DM) are considered to be at particularly high risk for cardiovascular disease. Over the last decade, the members of the peroxisome proliferator-activated receptor (PPAR) subfamily of nuclear receptors have emerged as valuable pharmacological targets whose activation can normalize metabolic dysfunctions and reduce some cardiovascular risk factors associated with T2DM. PPARalpha agonists, such as the fibrates, can correct dyslipidemia. PPARgamma agonists, such as the thiazolidinediones, act as insulin sensitizers and improve insulin resistance in patients with T2DM. Because of restricted potency and certain side-effects of PPAR agonists, as well as the increasingly epidemic incidence of T2DM, there is a real need for the development of selective PPAR agonists with improved clinical efficacy. This chapter focuses on the PPAR agonists currently used in the clinic, as well as on the discovery and development of the next generation of PPAR agonists.

Atherosclerotic cardiovascular disease (CVD) is the main cause of death in developed and developing countries. It is well accepted that several diseases - including hypertension, dyslipidemia and diabetes mellitus - increase CVD. More recently also chronic inflammatory diseases, such as rheumatoid arthritis, have been shown to accelerate CVD. This association further supports a responsible role for inflammatory processes in all stages of CVD pathophysiology. Clinically, CVD ranges through different acute and chronic syndromes with ischemic symptoms in distal tissues, including heart, cerebral region or peripheral arteries. Several treatments for reducing CVD are under investigation. In this review we focus on statins, angiotensin-converting-enzyme (ACE) inhibitors, and angiotensin-II receptor blockers (ARBs), updating therapeutic evidence from the last clinical trials with particular relevance to diabetic patients.

There has been a remarkable rise in the number of kidney transplant recipients (KTR) in the US over the last decade. Increasing use of potent immunosuppressants, which are also potentially diabetogenic and atherogenic, can result in worsening of pre-existing medical conditions as well as development of post-transplant disease. This, coupled with improving long-term survival, is putting tremendous pressure on transplant centers that were not designed to deliver primary care to KTR. Thus, increasing numbers of KTR will present to their primary care physicians (PCP) post-transplant for routine medical care. Similar to native chronic kidney disease patients, KTRs are vulnerable to cardiovascular disease as well as a host of other problems including bone disease, infections and malignancies. Deaths related to complications of cardiovascular disease and malignancies account for 60-65% of long-term mortality among KTRs. Guidelines from the National Kidney Foundation and the European Best Practice Guidelines Expert Group on the management of hypertension, dyslipidemia, smoking, diabetes and bone disease should be incorporated into the long-term care plan of the KTR to improve outcomes. A number of transplant centers do not supply PCPs with protocols and guidelines, making the task of the PCP more difficult. Despite this, PCPs are expected to continue to provide general preventive medicine, vaccinations and management of chronic medical problems. In this narrative review, we examine the common medical problems seen in KTR from the PCP's perspective. Medical management issues related to immunosuppressive medications are also briefly discussed.

Obstructive sleep apnea (OSA) is recurrent obstruction of the upper airway leading to sleep fragmentation and intermittent hypoxia (IH) during sleep. There is growing evidence from animal models of OSA that IH is independently associated with metabolic dysfunction, including dyslipidemia and insulin resistance. The precise mechanisms by which IH induces metabolic disturbances are not fully understood. Over the last decade, several groups of investigators developed a rodent model of IH, which emulates the oxyhemoglobin profile in human OSA. In the mouse model, IH induces dyslipidemia, insulin resistance and pancreatic endocrine dysfunction, similar to those observed in human OSA. Recent reports provided new insights in possible mechanisms by which IH affects lipid and glucose metabolism. IH may induce dyslipidemia by up-regulating lipid biosynthesis in the liver, increasing adipose tissue lipolysis with subsequent free fatty acid flux to the liver, and inhibiting lipoprotein clearance. IH may affect glucose metabolism by inducing sympathetic activation, increasing systemic inflammation, increasing counter-regulatory hormones and fatty acids, and causing direct pancreatic beta-cell injury. IH models of OSA have improved our understanding of the metabolic impact of OSA, but further studies are needed before we can translate recent basic research findings to clinical practice.

Early in the HIV epidemic, multiple endocrine and metabolic abnormalities were observed in HIV-infected patients. These abnormalities were either related glandular infection or infiltration with opportunistic diseases or the effects of systemic inflammation and severe illness on hormonal function and metabolic homeostasis. This review describes the epidemiology and pathogenesis of dyslipidemia, disorders of bone homeostasis, and dysfunction of the adrenal, gonadal, and thyroid axes in the untreated HIV-infected patient. While this review is most applicable to the HIV epidemic in the developing world where effective antiretroviral therapy is not available, understanding the effect of systemic inflammation on endocrine and metabolic function in the untreated HIV-infected person has valuable lessons for the pathogenesis of endocrine disease in HIV-infected patients receiving antiretroviral treatment.
