It has long been known that psychiatric patients experience increased morbidity and mortality associated with a range of physical disorders. Lifestyle, inadequate health care, and a variety of other factors all contribute to the poor physical health of people with severe mental illness. Second-generation antipsychotics have gained widespread acceptance for the management of patients with schizophrenia and other forms of severe mental illness. While demonstrating several advantages over first-generation antipsychotics, second-generation antipsychotics have been found to cause or exacerbate several metabolic disorders, including diabetes, obesity, dyslipidemia, and metabolic syndrome. These disorders are closely linked and consistently associated with the development of cardiovascular disease, with varying prevalence rates depending on the second-generation antipsychotic used. As a result, several authoritative guidelines have been developed for the monitoring and management of metabolic disturbances in schizophrenia and other forms of severe mental illness. Specifically, the guidelines and recommendations generated from the Mount Sinai Conference on Medical Monitoring and the American Diabetes Association/American Psychiatric Association Consensus Development Conference on Antipsychotic Drugs and Obesity and Diabetes call for a more integrated and cooperative approach between primary care physicians and mental health care providers to improve the quality of health care for people with severe mental illness. By routinely performing physical health monitoring, referrals, and/or treatment for patients with schizophrenia and other forms of severe mental illness, mental health care providers can take a lead role in transforming the current system of fragmented mental and physical health services into a system focused on early intervention, wellness, and recovery.

People with schizophrenia are at greater risk of obesity, Type 2 diabetes, dyslipidaemia and hypertension than the general population. This results in an increased incidence of cardiovascular disease (CVD) and reduced life expectancy, over and above that imposed by their mental illness through suicide. Several levels of evidence from data linkage analyses to clinical trials demonstrate that treatment-related metabolic disturbances are commonplace in this patient group, and that the use of certain second-generation antipsychotics may compound the risk of developing the metabolic syndrome and CVD. In addition, smoking, poor diet, reduced physical activity and alcohol or drug abuse are prevalent in people with schizophrenia and contribute to the overall CVD risk. Management and minimization of metabolic risk factors are pertinent when providing optimal care to patients with schizophrenia. This review recommends a framework for the assessment, monitoring and management of patients with schizophrenia in the UK clinical setting.

Patients with chronic mental illness have multiple health care needs. These patients, particularly those with schizophrenia, have higher incidences of heart disease and metabolic syndrome than the general population and show increased risks of infectious disease, pulmonary disease, and substance abuse. In order to effectively monitor and treat these patients, psychiatric and general health care should be integrated as much as possible. This presentation describes the role of the psychiatrist in helping to maintain the physical health of his or her patients, including monitoring for weight gain and other cardiac risk factors that may be increased by psychotropic medications, and explains the importance of communication between psychiatrists and primary care physicians.

Patients with mental illnesses such as schizophrenia and bipolar disorder have an increased prevalence of metabolic syndrome and its components, risk factors for cardiovascular disease and type 2 diabetes. Although the prevalence of obesity and other risk factors such as hyperglycemia are increasing in the general population, patients with major mental illnesses have an increased prevalence of overweight and obesity, hyperglycemia, dyslipidemia, hypertension, and smoking, and substantially greater mortality, compared with the general population. Persons with major mental disorders lose 25 to 30 years of potential life in comparison with the general population, primarily due to premature cardiovascular mortality. The causes of increased cardiometabolic risk in this population can include nondisease-related factors such as poverty and reduced access to medical care, as well as adverse metabolic side effects associated with psychotropic medications, such as antipsychotic drugs. Individual antipsychotic medications are associated with well-defined risks of weight gain and related risks for adverse changes in glucose and lipid metabolism. Based on the medical risk profile of persons with major mental illnesses, and the evidence that certain medications can contribute to increased risk, screening and regular monitoring of metabolic parameters such as weight (body mass index), waist circumference, plasma glucose and lipids, and blood pressure are recommended to manage risk in this population. Treatment decisions should incorporate information about medical risk factors in general and cardiometabolic risk in particular. In addition to the implications for individual clinicians, the problem of disparity in meeting healthcare needs for persons with mental illness in comparison with the general population has become an important public policy concern, with recent recommendations from the National Association of State Mental Health Program Directors and the Institute of Medicine. This article provides an overview of cardiometabolic risk in patients with major mental illness and describes steps for risk reduction.

The objective of this study was to determine the occurrence of metabolic abnormalities among previously unmedicated female patients with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition schizophrenia spectrum disorders and their associations with olanzapine and risperidone treatment. We analysed 94 female patients who were treated with olanzapine or risperidone in the period of 3 months. Analysed variables included fasting glucose, total cholesterol, low-density lipoprotein (LDL), high-density lipoproteins and triglycerides in blood, blood pressure (BP), waist and hip circumferences and body mass index (BMI). At baseline, 14 patients (15%) fulfilled criteria for metabolic syndrome. After 3 months of treatment, 25 patients (27%) fulfilled criteria for metabolic syndrome, and their baseline BMI was the only predictor for its development. Treatment with both antipsychotics was associated with significant increase in waist circumference. Positive family history of diabetes mellitus contributed to a significant greater increase in abdominal obesity, significant higher baseline levels and a borderline significant increase in fasting glucose among olanzapine-treated patients. Olanzapine admission was associated with a significant increase in LDL and risperidone with a significant increase in triglycerides. Metabolic abnormalities seem to be more prevalent in unmedicated female patients with schizophrenia spectrum disorders than expected based on results in general population (adjusted for age and sex). Olanzapine treatment might induce significant alterations in metabolic profiles, especially among patients with positive family history of diabetes, mostly by inducing abdominal obesity. The association of risperidone application and increase in triglyceride level still needs to be determined.

Patients with bipolar disorder have been found to have high rates of endocrine and cardiovascular disorders as well as obesity. Some health problems may be influenced by the psychiatric disorder itself, and, similarly, health problems may influence the course of bipolar disorder. Further, some pharmacologic treatments used for bipolar disorder have been associated with obesity, diabetes, hyperglycemia, dyslipidemia, metabolic syndrome, prolonged QTc, and thyroid dysfunction. To optimize care and achieve the best possible treatment outcomes, integrated psychiatric and medical care is needed.

Obesity is reaching epidemic proportions worldwide and it is correlated with various comorbidities, among which the most relevant are diabetes mellitus, arterial hypertension, and cardiovascular diseases. Obesity management is a modern challenge because of the rapid evolution of unfavorable lifestyles and unfortunately there are no effective treatments applicable to the large majority of obese/overweight people. The current medical attitude is to treat the complications of obesity (e.g. dyslipidemia, hypertension, diabetes, and cardiovascular diseases). However, the potential of treating obesity is enormous, bearing in mind that a volitional weight loss of 10 kg is associated with important risk factor improvement: blood pressure -10 mmHg, total cholesterol -10%, LDL cholesterol -15%, triglycerides -30%, fasting glucose -50%, HDL cholesterol +8%. Drug treatment for obesity is an evolving branch of pharmacology, burdened by severe side effects and consequences of the early drugs, withdrawn from the market, and challenged by the lack of long-term data on the effect of medications on obesity-related morbidity and mortality, first of all cardiovascular diseases. In Europe three antiobesity drugs are currently licensed: sibutramine, orlistat, and rimonabant; important trials with clinical endpoints are ongoing for sibutramine and rimonabant. While waiting for their results, it is convenient to evaluate these drugs for their effects on body weight and cardiometabolic risk factors. Sibutramine is a centrally acting serotonin/noradrenaline reuptake inhibitor that mainly increases satiety. At the level of brown adipose tissue, sibutramine can also facilitate energy expenditure by increasing thermogenesis. The long-term studies (five) documented a mean differential weight reduction of 4.45 kg for sibutramine vs placebo. Considering the principal studies, attrition rate was 43%. This drug not only reduces body weight and waist circumference, but it decreases triglycerides and uric acid as well and it increases HDL cholesterol; in diabetics it improves glycated hemoglobin. Sibutramine has conflicting effects on blood pressure: in some studies there was a minimal decrease, in some others a modest increase. In all the studies this drug increased pulse rate. Sibutramine is not recommended in patients with uncontrolled hypertension, or in case of history of cardio- and cerebrovascular disease. Orlistat is a pancreatic lipase inhibitor that reduces fat absorption by partially blocking the hydrolysis of dietary triglycerides. A recent meta-analysis evaluated 22 studies lasting for at least 12 months, in obese patients with a mean body mass index of 36.7 kg/m2, where orlistat was associated with hypocaloric diet or behavioral interventions: the net average weight loss was 2.89 kg (confidence interval 2.27-3.51 kg). Considering the principal studies, attrition rate ranged from 33 to 57%. Orlistat significantly decreases waist circumference, blood pressure, total and LDL cholesterol, but has no effect on HDL and triglycerides. This drug significantly reduced the incidence of diabetes only in subjects with impaired glucose tolerance. The major adverse effects with orlistat are mainly gastrointestinal (fatty and oily stool, fecal urgency, oily spotting, fecal incontinence) and attenuate over time. Orlistat should be avoided in patients with chronic malabsorption and cholestasis. Rimonabant is a selective antagonist of cannabinoid type 1 receptor. This drug, by inhibiting the overactivation of the endocannabinoid system, produces anorectic stimuli at the central nervous level, but also has effects on the peripheral systems involved in metabolism control, such as liver, adipose tissue, skeletal muscles, endocrine pancreas, and gastrointestinal apparatus, influencing many processes partially unknown. An ample experimental program named RIO (Rimonabant In Obesity) involved about 6600 obese or overweight patients to identify the effects of rimonabant in weight loss and associated cardiometabolic abnormalities, over and beyond a caloric restriction of 600 kcal in the treatment and placebo arms. In the four double-blind RIO trials published (Rio-North America, RIO-Europe, RIO-Lipids, RIO-Diabetes), rimonabant 20 mg significantly (p <0.001) reduced weight by 6.3-6.9 kg in the non-diabetic groups vs placebo (-1.5-1.8 kg), whereas in the diabetic subjects enrolled in RIO-Diabetes, weight loss was 5.3 vs 1.4 kg in the placebo group. Attrition rate at 1 year ranged between 40 and 50%, similar to the studies with sibutramine or orlistat. Similarly to weight loss, also waist circumference was significantly reduced by rimonabant. As for cardiometabolic parameters, rimonabant induced a significant increase in HDL cholesterol and a significant decrease in triglycerides. Even if no significant LDL reduction was achieved, the RIO-Lipids study showed a significant decrease in small dense LDL particles, more atherogenic, in rimonabant-treated subjects. Non-diabetic treated patients improved basal insulin and indirect indexes of insulin resistance, while in the RIO-Diabetes study, the only one including diabetics, glycated hemoglobin improved by 0.7% in the active treatment arm vs placebo. The effects on HDL cholesterol and glycated hemoglobin seem in a large percentage unrelated to weight loss. These effects have been confirmed by another trial, named SERENADE, evaluating the treatment in naive diabetic patients. Rimonabant is not recommended in patients with a history of depressive disorders or suicidal ideation and with uncontrolled psychiatric illness, and is contraindicated in patients with ongoing major depression or ongoing antidepressive treatment. In conclusion, despite an enormous advancement in basic research to understand the pathogenetic mechanisms at the base of obesity, the pharmacological research did not reach the therapeutic opportunities available for other chronic conditions, like hypertension and dyslipidemia. However, the few molecules available for clinical practice (sibutramine, orlistat, rimonabant) have shown, when properly used, to contribute to reduce body weight and undoubtedly improve cardiometabolic risk factors. With this preamble, according to current guidelines and pharmacoeconomic studies, patients who might benefit from antiobesity treatment are those with a body mass index > or =30 or 27-29.9 kg/m2 with major obesity-related comorbidities such as hypertension, diabetes, dyslipidemia, obstructive sleep apnea, and metabolic syndrome.

The objective was to explore the impact on physical health of a lifestyle programme among persons with psychiatric disabilities, and their caregivers. Their satisfaction with the intervention was also assessed. Somatic comorbidity and an increased mortality related to the lifestyle among persons with psychiatric disabilities are well known. Few randomized controlled trials have been aimed specifically at lifestyle issues among persons with a psychiatric disability. This trial includes clients with psychiatric disabilities living in supported housing and their staff. Forty-one persons with a DSM-?V diagnosis of severe mental illness from psychiatric disability from 10 supported housing facilities and 41 of their caregivers participated in this 12-month study during 2005-2006 in Sweden. The supported housing facilities with residents and staff were randomly assigned to either a health intervention programme or a control programme with an aesthetic content. The presence of metabolic syndrome and changes in the mean of physiological parameters such as Hba1c, P-glucose, P-insulin, lipids, blood pressure, physical working capacity, body mass index, Heart Score were investigated and participants' satisfaction assessed. There was a significant reduction in the mean of metabolic syndrome criteria in the intervention group compared with the control group at the follow-up. The participants expressed satisfaction with the programme. The results indicate that health interventions on lifestyle issues when involving carers are appreciated, feasible and could be successful in reducing some health-related risk factors among persons with psychiatric disabilities.

The high prevalence of metabolic syndrome (MetS) in people with a mental illness has been reported recently in the literature. Gaps have emerged in the widespread use of systematic screening methods that identify this collection of critical risk factors for cardiac and metabolic disorders in people with severe mental illness. A sample (n = 103) of consumers with severe mental illness was screened for MetS using the Metabolic Syndrome Screening Tool and compared to a sample (n = 72) of consumers who were not receiving a systematic approach to screening for MetS. The results demonstrated ad hoc screening of consumers for MetS in the comparison group, potentially leaving patients at risk of cardiac and metabolic disorders being untreated. Mental health nurses are well placed to show leadership in the screening, treatment, and ongoing management of MetS in people with severe mental illness. A potential new speciality role entitled the 'cardiometabolic mental health nurse' is proposed as a means leading to improved outcomes for consumers who have both the complication of physical health problems and a severe mental illness.

Metabolic syndrome and other cardiovascular risk factors are highly prevalent in people with schizophrenia. Patients are at risk for premature mortality and overall have limited access to physical health care. In part these cardio-metabolic risk factors are attributable to unhealthy lifestyle, including poor diet and sedentary behaviour. But over recent years it has become apparent that antipsychotic agents can have a negative impact on some of the modifiable risk factors. The psychiatrist needs to be aware of the potential metabolic side effects of antipsychotic medication and to include them in the risk/benefit assessment when choosing a specific antipsychotic. He should also be responsible for the implementation of the necessary screening assessments and referral for treatment of any physical illness. Multidisciplinary assessment of psychiatric and medical conditions is needed. The somatic treatments offered to people with severe and enduring mental illness should be at par with general health care in the non-psychiatrically ill population.
