Diabetes mellitus is a disease with major long-term implications, not only for the health and well-being of affected individuals, but also for costs to the National Health Service. Treatment of the disease and its complications takes up 4-5% of total health care expenditure in the U.K. These costs are dominated by in-patient care for the complications arising from diabetes. This paper presents a review of studies which have been carried out on the costs of diabetes and its complications. For such a chronic and potentially disabling disease with numerous complications it is surprising that costs have not been more extensively researched. A large amount of data are available about the implications of diabetes in terms of incidence and prevalence, but few costs have been collected, particularly indirect and marginal costs. Both insulin dependent (IDDM) and non-insulin dependent (NIDDM) diabetic patients exhibit similar complications so that the cost of treatment may be comparable, but further studies are needed to establish this. In addition, few studies have included diabetes as a secondary diagnosis. The studies which are available have tended to focus on direct costs, for example, the costs of hospital care, consultations and drugs, because they are the easiest to measure. Fewer studies have included indirect costs, such as the effect of time lost from work, early retirement and premature death, because of the difficulties in assigning monetary values to these factors. The most important contributors to the costs of diabetes are those of treating complications such as eye and limb disease, heart disease, neuropathy and nephropathy.(ABSTRACT TRUNCATED AT 250 WORDS)

Non-insulin-dependent diabetes mellitus (NIDDM) is a chronic disabling disease, that shortens length of life and implies a high burden for a community. Its prevalence goes from 0 per cent in Papua, New Guinea to 34 per cent in Pima Indians. There are very few prevalence studies in Mexico, and the strength of association of the known risk factors with the occurrence of the disease is not established. A prevalence cross sectional study was carried out with users of a first level medical care unit, with a meter measure of capillary glucose levels. Those with a previous diagnosis of diabetes or whose capillary glucose level were 200 mg or over were considered diabetics. Hyperglycemia was when the levels were recorded between 121 and 199 mg. The crude prevalence of NIDDM was 5.6 per cent (CI 95% 4.5-6.8), With almost no sex difference. Hyperglycemia prevalence was 2.9 per cent (CI 95% 2.0-3.7). Age was the main risk factor for the development of NIDDM. Those between 40 and 59 years showed a high risk (OR 10.8; CI 95% 5.4-22.0; p < 0.0001), and it was greater for the 60 years or elder (OR 20.6; CI 95% 9.8-44.1; p < 0.0001). Weight was also an important risk factor, with a 2.7 fold greater risk for obese persons (CI 95% 1.6-4.6; p < 0.0001). Other, risk factors were familiar history of diabetes (OR 1.5; CI 95% 0.9-2.3; p = 0.096), and overcrowding (OR 1.9; CI 95% 1.0-3.4; p = 0.03). In order to analyze independently each variable, a logistic regression model was applied, and a similar strength of association was observed for the crude model, but for obesity whose effect was modified by age. When only new cases were analyzed in the former model, the association with obesity was maintained. There is a need to develop prevalence studies of NIDDM in Mexico and to measure the strength of association with the known and the not jet well known risk factors of this disease in order to establish health policies according to the Mexican reality.

The United States is experiencing an epidemic of obesity among both adults and children. Approximately 35 percent of women and 31 percent of men age 20 and older are considered obese, as are about one-quarter of children and adolescents. While government health goals for the year 2000 call for no more than 20 percent of adults and 15 percent of adolescents to be obese, the prevalence of this often disabling disease is increasing rather than decreasing. Obesity, of course, is not increasing because people are consciously trying to gain weight. In fact, tens of millions of people in this country are dieting at any one time; they and many others are struggling to manage their weight to improve their appearance, feel better, and be healthier. Many programs and services exist to help individuals achieve weight control. But the limited studies paint a grim picture: those who complete weight-loss programs lose approximately 10 percent of their body weight, only to regain two-thirds of it back within 1 year and almost all of it back within 5 years. These figures point to the fact that obesity is one of the most pervasive public health problems in this country, a complex, multifactorial disease of appetite regulation and energy metabolism involving genetics, physiology, biochemistry, and the neurosciences, as well as environmental, psychosocial, and cultural factors. Unfortunately, the lay public and health-care providers, as well as insurance companies, often view it simply as a problem of willful misconduct--eating too much and exercising too little. Obesity is a remarkable disease in terms of the effort required by an individual for its management and the extent of discrimination its victims suffer. While people often wish to lose weight for the sake of their appearance, public health concerns about obesity relate to this disease's link to numerous chronic diseases that can lead to premature illness and death. The scientific evidence summarized in Chapter 2 suggests strongly that obese individuals who lose even relatively small amounts of weight are likely to decrease their blood pressure (and thereby the risk of hypertension), reduce abnormally high levels of blood glucose (associated with diabetes), bring blood concentrations of cholesterol and triglycerides (associated with cardiovascular disease) down to more desirable levels, reduce sleep apnea, decrease their risk of osteoarthritis of the weight-bearing joints and depression, and increase self-esteem. In many cases, the obese person who loses weight finds that an accompanying comorbidity is improved, its progression is slowed, or the symptoms disappear. Healthy weights are generally associated with a body mass index (BMI; a measure of whether weight is appropriate for height, measured in kg/m2) of 19-25 in those 19-34 years of age and 21-27 in those 35 years of age and older. Beyond these ranges, health risks increase as BMI increases. Health risks also increase with excess abdominal/visceral fat (as estimated by a waist-hip ratio [WHR] > 1.0 for males and > 0.8 for females), high blood pressure (> 140/90), dyslipidemias (total cholesterol and triglyceride concentrations of > 200 and > 225 mg/dl, respectively), non-insulin-dependent diabetes mellitus, and a family history of premature death due to cardiovascular disease (e.g., parent, grandparent, sibling, uncle, or aunt dying before age 50). Weight loss usually improves the management of obesity-related comorbidities or decreases the risks of their development. The high prevalence of obesity in the United States together with its link to numerous chronic diseases leads to the conclusion that this disease is responsible for a substantial proportion of total health-care costs. We estimate that today's health-care costs of obesity exceed $70 billion per year.(ABSTRACT TRUNCATED AT 400 WORDS)

Type 2 diabetes mellitus is a common disabling disease with onset in middle-aged individuals, caused by an imbalance between insulin production and action. Genetic studies point to major genetic components, but, with the exception of maturity-onset diabetes of the young (MODY), specific diabetes susceptibility genes remain to be identified. Recent studies showed that a dominant negative mutation in the insulin promoter factor-1 (IPF-1), a pancreatic beta-cell specific transcription factor, causes pancreatic agenesis and MODY. Thus, we investigated 192 French, non-MODY type 2 diabetic families for mutations in IPF-1. We identified 3 novel IPF-1 mutations, including 2 substitutions (Q59L and D76N) and an in-frame proline insertion (InsCCG243). Functional transactivation assays of these IPF-1 mutant isoforms in a beta-pancreatic tumor cell line transfected with a transcriptional reporter and IPF-1 expression plasmids demonstrate a significant inhibition of basal insulin promoter activity (stronger with the InsCCG243 mutant). We find that the InsCCG243 mutation is linked, in 2 families, to an autosomal dominant-like late-onset form of type 2 diabetes, in which insulin secretion becomes progressively impaired. The lower penetrance D76N and Q59L mutations were more prevalent and were associated with a relative risk of 12.6 for diabetes and with decreased glucose-stimulated insulin-secretion in nondiabetic subjects. We propose that IPF-1 mutations can cause MODY or apparently monogenic late-onset diabetes and that they represent a significant risk factor for type 2 diabetes in humans.

Erythromelalgia is a rare poorly understood clinical condition characterized by intense burning pain, pronounced erythema, and increased skin temperature. Although there are many classifications of the disease, it can basically be divided into primary, which begins spontaneously at any age, and secondary, which is associated with myeloproliferative disorders-related thrombocythemia, polycythemia, collagen-vascular diseases, diabetes mellitus, peripheral neuropathy, autoimmune and infectious diseases, and use of certain medicaments. A wide variety of etiological conditions can cause erythromelalgia, all having a single common pathogenetic mechanism - microvascular arteriovenous shunting. The disease is characterized by severe pain associated with redness and hotness in extremities. The diagnosis is based on the medical history and clinical findings. The most useful oral medications for erythromelalgia seem to be aspirin, propranolol, clonazepam, cyproheptadine, drugs inhibiting serotonin re-uptake (venlafaxine and sertraline), tricyclic antidepressants (amitriptyline, imipramine), anticonvulsants (gabapentin), calcium antagonists (nifedipine, diltiazem), and prostaglandins (micoprostol). Erythromelalgia is usually chronic, sometimes progressive, and disabling disease, which can greatly affect the quality of life. Some patients have stable disease and get better, or even experience full resolution of the disease, with time. This review article presents the etiological basis, diagnostics, and therapy of erythromelalgia.

Peripheral arterial disease (PAD), when accompanied by claudication, is a disabling disease that affects 12 percent of the population of the United States (US). PAD is associated with increased mortality as well as decreased functional status and quality of life. Smoking cessation and treatment of diabetes are key aspects of risk factor modification for the PAD patient as well as controlling other cardiovascular risk factors. Typically, only the most severely diseased patients with PAD receive surgery for the indication of claudication and other therapeutic options are being sought. Exciting developments are taking place in the area of drug development for instance. The benefits of a supervised walking exercise program have been consistently demonstrated in persons with PAD and therefore, exercise rehabilitation constitutes an important form of therapy for these persons. Unfortunately, in the US, exercise rehabilitation is not always reimbursed which may lessen its utility presently. All therapies which are used to treat claudication should incorporate measures of functional status and quality of life in addition to treadmill walking in order to ascertain the benefit of a given treatment for patients with PAD.

Diabetes mellitus can lead to metabolic changes that alter normal hepatic and biliary function and structure. These alterations in hepatic and biliary function and structure are usually benign, but in certain situations lead to significant, disabling disease. This article reviews the hepatic and biliary complications of diabetes, with emphasis on epidemiology, diagnosis, and management, as well as the glucose intolerance seen in liver disease.

Stroke is a deadly and disabling disease that preferentially afflicts older adults. It shares common risk factors with myocardial infarction (MI), such as hypertension, diabetes, and hyperlipidemia. Blood pressure control, cholesterol reduction with statins, and glucose control reduce the risk for both stroke and MI. Additionally, management of atrial fibrillation with warfarin reduces stroke risk. Beyond risk factor reduction, antiplatelet therapy is an effective option for lowering the likelihood of stroke in at-risk patients. Among antiplatelet agents, aspirin has been shown effective for secondary stroke prevention as well as primary and secondary MI prevention; clopidogrel for secondary stroke and MI prevention; and both ticlodipine and dipyridamole for secondary stroke prevention. Combining antiplatelet agents is rational. Carotid endarterectomy should be considered for stroke prevention in patients with ischemic symptoms; for patients with asymptomatic stenosis, potential benefit must be balanced against surgical risk.

Matrix metalloproteinases (MMP) and their inhibitors (TIMP) are central factors in the control of extracellular matrix turnover. They are important in normal physiology and also during a range of pathological states. In this review, we have systematically identified clinical articles relevant to cardiovascular disease in diabetes from the last 10 years. Our aim was to outline the structure, function and regulation of metalloproteinases and their key roles in cardiomyopathy and vasculopathy in diabetes. We also explore the effects of drug intervention on both human subjects with diabetes and experimental animal models. The modulation of MMP and TIMP activity using drugs that affect the expression and function of these proteins may provide us with new ways to treat this serious and disabling disease, and we explore potential mechanisms and treatments.

Obesity is a disabling disease which has gained greater attention worldwide and particularly in the United States. It significantly increases the risk for other diseases such as insulin independent diabetes mellitus also known as diabetes type 2. The most common surgical procedure for obesity is liposuction. It is traditionally performed either as small-volume liposuction or large-volume liposuction, the majority being small-volume liposuction procedures. Large-volume and small-volume liposuction have been clinically shown to improve insulin sensitivity in obese patients thus reducing their risk of developing type 2 diabetes. In this paper, evidence is presented to support the hypothesis that liposuction disrupts the pathway that brings about insulin insensitivity in the obese patient. It is proposed that using liposuction in the overall treatment of obesity could lead to an improvement in insulin sensitivity and thus greatly improve the quality of life of the obese patient.
