Metabolic considerations in the use of antipsychotic medications: A review of recent evidence
ABSTRACT Compared with the general population, persons with schizophrenia have up to a 20% shorter lifespan, with cardiovascular disease as the leading cause of death. In addition, persons with schizophrenia have increased prevalence of the metabolic syndrome (obesity, insulin resistance, dyslipidemia, impaired glucose tolerance, and hypertension), increased prevalence of risk factors such as smoking, poverty, and poor nutrition, and reduced access to medical care. Results from the recent Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) provide further evidence of the metabolic risk associated with different atypical antipsychotics. Based on this study and a growing number of other randomized clinical trials, clozapine and olanzapine treatment can produce substantial mean changes in weight and an increased risk of associated metabolic disturbances. Risperidone and quetiapine treatment can produce intermediate changes in mean weight in comparison to treatment with other atypical antipsychotics, with discrepant results with respect to metabolic risk. Aripiprazole and ziprasidone treatment induced the lowest mean changes in weight gain and had no effect on risk for adverse metabolic changes, among currently available atypical agents. Considerable evidence indicates that mentally ill patients often do not receive adequate recognition of, monitoring of, or care for their medical illnesses. There is a critical need for psychiatrists and primary care professionals to increase awareness of and attention to the physical health problems of persons with mental illness, including appropriate management of metabolic adverse events associated with psychiatric medications.

ABSTRACT: Objective: Several studies indicate increased prevalence of metabolic syndrome (MetS) among patients with psychiatric disorders as well as among individuals with gender dysphoria (GD) treated by cross-sex hormonal treatment. However, the MetS prevalence among hormone treated GD individuals suffering from psychiatric problems has not been detected. Methods: From a sample of 146 GD patients we selected 122 metabolically healthy individuals in order to investigate the prevalence of MetS after the beginning of the cross-sex hormonal treatment in a 2 year follow-up assessment. Furthermore, we assessed differences in MetS prevalence between hormone treated GD patients with and without concomitant psychiatric problems. Results: When treated with hormone therapy, GD patients reported changes in several parameters which are clustered in MetS, with statistically significant differences compared to baseline. Glyco-insulinemic alterations were more pronounced in male to female patients (MtFs). However, weight gain, waist circumference increases, blood pressure increases, and lipid alterations were similar in MtFs and female to male patients (FtMs). 14.8% of the sample at year 1 and 17.2% at year 2 developed MetS. Among patients with concomitant psychiatric problems, 50% at year 1 and 55% at year 2 developed MetS against 8% at year 1 and 10% at year 2 of patients without concomitant psychiatric problems. Conclusion: This study indicates that sex hormones induce MetS in a relatively low proportion of healthy GD individuals and especially during the first year of hormonal treatment. Most importantly, concomitant psychiatric problems are associated with considerably greater MetS prevalence in hormone treated GD individuals.Journal of Psychosomatic Research 02/2015; 78(4).

ABSTRACT: The prevalence rate of metabolic syndrome (MS) and coronary artery disease (CAD) has been found to be high in patients with chronic schizophrenia. Current evidence shows that CAD is underdiagnosed in this group. Our study evaluated the prevalence of MS and the risk of CAD in patients with chronic schizophrenia in a chronic care mental hospital in southern Taiwan. We included all patients with the diagnosis of schizophrenia or schizoaffective disorder. We collected all laboratory, physical examination, psychiatric interview, and chart review data. We also evaluated the risk of CAD in these patients using the Framingham point system. There was no significant age difference in the MS prevalence rate in these patients. The young patients with schizophrenia in our study tended to have a higher prevalence of MS than the general population. In addition, female patients had a higher prevalence rate of MS than males. Based on the Framingham point system, we found the 10-year risk of CAD to be higher among the patients with schizophrenia than in the general population. Our study highlights the importance of the high risk of MS in both younger and older patients with schizophrenia, without a significant relationship to the use of antipsychotics. More complete cohort studies are needed to confirm these findings. Psychiatrists may want to establish more specific and detailed clinical guidelines for patients with chronic schizophrenia with comorbid physical diseases, especially MS and CAD.The Kaohsiung journal of medical sciences 11/2014; DOI:10.1016/j.kjms.2014.09.002 · 0.81 Impact Factor

ABSTRACT: Objective To explore the temporal relationship between 9/11-related posttraumatic stress disorder (PTSD) and new-onset diabetes in World Trade Center (WTC) survivors up to 11 years after the attack in 2001. Methods Three waves of surveys (conducted from 2003 to 2012) from the WTC Health Registry cohort collected data on physical and mental health status, sociodemographic characteristics, and 9/11-related exposures. Diabetes was defined as self-reported, physician-diagnosed diabetes reported after enrollment. After excluding prevalent cases, there were 36,899 eligible adult enrollees. Logistic regression and generalized multilevel growth models were used to assess the association between PTSD measured at enrollment and subsequent diabetes. Results We identified 2143 cases of diabetes. After adjustment, we observed a significant association between PTSD and diabetes in the logistic model [adjusted odds ratio (AOR) 1.28, 95% confidence interval (CI) 1.14–1.44]. Results from the growth model were similar (AOR 1.37, 95% CI 1.23–1.52). Conclusion This exploratory study found that PTSD, a common 9/11-related health outcome, was a risk factor for self-reported diabetes. Clinicians treating survivors of both the WTC attacks and other disasters should be aware that diabetes may be a long-term consequence.Preventive Medicine 09/2014; 66.
