  • This study was performed to evaluate the relationship between insulin-mediated glucose disposal and fat distribution in black males and females with type 2 diabetes. Female subjects had a substantially higher total fat volume than males, although abdominal fat volume did not differ between males and females. Despite these differences, glucose disposal decreased as the amount of adipose tissue increased, and this relationship was similar in males and females. The study concluded that abdominal fat, and not gender or subcutaneous fat, was the best predictor of impaired glucose regulation in this group of diabetics. It has been hypothesized that abdominal adipocytes may be more insulin-resistant than subcutaneous adipocytes and therefore more likely to generate free fatty acids.   Banerji MA.

  • Many factors contribute to the increased risk for medical comorbidities in patients with schizophrenia or other mental illnesses. These are related to the illness itself, health behaviours, drug treatments and system of care. Psychiatrists do not always address the detection and treatment of physical illness in their patients. However, co-morbid conditions may adversely affect the treatment and clinical course of schizophrenia, hence it is important that these are considered as part of the management of patients. This slide summarizes the various sources of risks for medical comorbidities in patients with mental illness. 1 Increased risk for medical illness in people with major mental disorders may be related to the disease itself. The negative symptoms of schizophrenia, including loss of social skills, drive, and motivation, may place the patient at increased medical risk. In addition, ongoing psychiatric symptoms can make it difficult for patients to coherently communicate their medical needs. The incidence of illnesses such as diabetes may also be inherently higher among those with schizophrenia or bipolar disorder, placing the individual at greater risk of diabetes-related morbidity. An unhealthy lifestyle, which might include high-risk behaviours such as smoking, substance abuse, lack of exercise, and poor diet, can certainly contribute to medical risk in people with major mental disorders. Substance and alcohol abuse leading to intravenous drug use and unsafe sex may also contribute to the prevalence of HIV/AIDS and hepatitis C in these patients. Treatment-related comorbidity results primarily from the use of neuroleptic and anticholinergic medications. Side effects associated with antipsychotics include weight gain, diabetes, hyperlipidaemia and hyperprolactinaemia — all of which increase metabolic risk and cardiovascular disease. In addition, r esearch has shown that patients with schizophrenia may suffer a downward socioeconomic shift that adversely affects their access to healthcare. Infrastructural barriers in the health care system, combined with fragmentation of healthcare services, can also create impediments to good care for those with major mental disorders. 1.

  • This slide illustrates the cumulative effect of risk factors and illustrates that risk factors are more than additive; the total risk is higher than just the sum of the individual risk factors. Monitoring of a USA population cohort in the town of Framingham, Massachusetts, USA, for the period of 12 years led to the identification of the major CVD risk factors, including high blood pressure, high total blood cholesterol, smoking, obesity and diabetes. Odds ratio for each of these risk factors alone ranges from around 1.2 to 2.2. When more than one factor is present, odds ratios are increased by more than an additive rate, so that all five (BMI>27, smoking, high total cholesterol, diabetes and hypertension) led to an approximate 7-fold increased risk compared to any one risk factor alone. 1.

  • The major cardiovascular risk factors revealed in the Framingham study (obesity, smoking, diabetes and hypertension and dyslipidaemia) are those that, in the general population, are modifiable by behavioural changes and improved care. Individuals with schizophrenia are at increased risk for modifiable cardiovascular risk factors than the general population as shown in this slide. These risk factors are a major contributor to increased mortality in schizophrenia. The increased cardiovascular risks in the schizophrenic population highlights the need for intervention in this patient population to improve overall patient health. Although diabetes cannot be considered a modifiable risk factor, maintainence of good glycaemic control by can prevent the progression of the impaired fasting glucose to full blown diabetes.

  • This slide summarises the criteria for defining metabolic syndrome according to the National Cholesterol Education Program (NCEP). NCEP published their updated recommendations for cholesterol testing and management in The Third Report of the Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (Adult Treatment Panel III, or ATP III). 1.

  • This slide illustrates the pooled incidence of clinically significant weight gain reported in the US product labels for aripiprazole, risperidone, quetiapine, and olanzapine. All data were obtained in placebo-controlled trials, with clinically meaningful weight gain defined as ≥ 7% increase in body weight from baseline (about 10 pounds for a woman and 15 pounds for a man), which is considered by the National Institutes of Health to be the threshold for the development of serious adverse effects. As seen in this graph, compared with placebo, clinically significant weight gain occurred in 29% of the patients taking olanzapine, 1 23% taking quetiapine, 2 18% taking risperidone, 3 and 8% taking aripiprazole. 4 With long-term exposure to olanzapine (median 238 days), up to 56% of patients experienced clinically significant weight gain. 1 These data provide a guide to clinicians about what to expect when choosing an atypical antipsychotic in terms of relative weight gain and potentially weight-related metabolic disturbances.

  • This was a double-blind, multi-center study to compare long-term weight effects of aripiprazole and olanzapine in patients with acute relapse of schizophrenia. Patients were randomized to aripiprazole (15-30 mg/day; n=154 ) or olanzapine (10-20 mg/day; n=156) for 26 weeks. Significant differences in mean weight change were observed throughout the study; at Week 26, there was a mean weight increase of 4.23 kg with olanzapine and a mean weight loss of 1.37 kg with aripiprazole ( P <0.001), a difference of 5.6 kg.
  • This slide lists some of the studies that have demonstrated the higher prevalence of diabetes or impaired glucose tolerance in schizophrenia and bipolar disorder. In a 2003 study, Ryan et al demonstrated that first-episode, drug-naive patients with schizophrenia have impaired fasting glucose tolerance significantly more often than healthy control subjects (P< 0.02). 1 Dixon et al examined Medicare and Medicaid data from 1991, a time predating the widespread use of atypical antipsychotics. H igher rates of diabetes were seen for patients with schizophrenia than the general population. 2 The study by Lilliker (1980), conducted a decade before atypical antipsychotics came into existence, similarly observed that diabetes occurred more often in patients with bipolar disorder than in the general population. 1.

  • Despite the limitations of database analyses, further evidence from case reports supports the link between some atypical antipsychotic and diabetes. This slide shows data from the FDA MedWatch Drug Surveillance System together with published reports and meetings abstracts that were used to identify reports of diabetes or hyperglycemia associated with each of the treatments. Analysis of cases identified from the FDA MedWatch system provides support for an association between clozapine and olanzapine therapy and diabetes development. 1. Koller E et al.
