Abstract
Background Metabolic syndrome (MetS) is a concern in psychiatric patients. We aimed to study the influence of the modifiable lifestyle factors on MetS in adult psychiatric patients along with associated clinical factors and quality of life. Methods Factors such as diet (Healthy Eating Index), exercise, substance use, cardiovascular risk (QRISK), illness severity (Clinical Global Impression), medications, adverse events (Systematic Monitoring of Adverse Events Related to Treatments), and quality of life (Recovering Quality of Life Scale) were assessed along with clinical components for MetS in 323 psychiatric patients receiving routine care and monitoring in a Community Mental Health Team. Results MetS was present in 50.5% (95% CI: 45.0-55.9). It was significantly associated with higher age, duration of mental illness, body mass index (BMI), QTc, QRISK, and antipsychotic drugs. In logistic regression, age, QTc, QRISK, and BMI remained significantly linked to MetS. Patients with or without MetS were comparable in their lifestyle factors such as diet, exercise, and substance use, along with the family history of metabolic disorders, age at onset of mental illness, duration of antipsychotic medication, side effects, psychiatric diagnoses, and quality of life. However, many patients with or without MetS had poorer diet and physical inactivity, indicating scope for interventions. Conclusions Around half of the psychiatric patients had MetS, and modifiable lifestyle factors did not differentiate individuals with or without MetS. The need for further research on the prevention and management of MetS in psychiatric patients is highlighted.

Prevalence of the metabolic syndrome and associated factors among inpatients with severe mental illness in Botswana: a cross-sectional study. BMC Cardiovasc Disord 2022; 22:515. [PMID: 36460970 PMCID: PMC9717503 DOI: 10.1186/s12872-022-02939-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Accepted: 11/08/2022] [Indexed: 12/03/2022] Open
Abstract
INTRODUCTION The metabolic syndrome, a cluster of inter-related risk factors for cardiovascular diseases is highly prevalent among individuals with obesity and sedentary lifestyle. Chronic psychiatric disorders such as severe mental illness are associated with increased risk for cardiovascular diseases. We aimed to assess the prevalence and correlates of metabolic syndrome among inpatients with severe mental illness in a resource limited setting with high HIV prevalence. METHODS This was a cross-sectional study among adult inpatients at a referral psychiatric hospital in Botswana. We used convenience sampling to enrol participants available at the time of the study. The National Cholesterol Education Program Adult Treatment Panel-III (NCEP-ATP III) criteria was used to define the metabolic syndrome. Data were analysed using descriptive statistics as well as multiple logistic regression modelling. RESULTS A total of 137 participants were enrolled. Of these, 119 (87%) had complete data for the main analysis. The overall prevalence of metabolic syndrome was 22.6% (95% CI 15.9, 30.6) and did not differ significantly by gender or HIV status. Age was significantly associated with the risk of having the metabolic syndrome while gender, body mass index, HIV status, and days of moderate physical activity were not. CONCLUSION There was a moderately high prevalence of metabolic syndrome. Thus, the management of individuals with severe mental illness in resource limited settings should include assessment of cardiovascular risk and target modifiable risk factors in this population. Consideration for the patient's age should be made when rationalizing the limited resources available for assessing metabolic syndrome among patients with severe mental illness.

Abstract
Metabolic syndrome (MetS) in patients with schizophrenia occurs 2-3 times more frequently than in the general population. Antipsychotic medication is a primary risk factor for patients with MetS. In particular, the widely used second-generation antipsychotics can affect glucose and lipid metabolism and can induce insulin resistance and other metabolic abnormalities through various receptors. Notably, the metabolic risks of various antipsychotics may differ because of their different pharmacological affinity to MetS-related receptors. Several previous studies have shown that switching from high to low metabolic risk antipsychotics may improve patients' metabolic parameters. The current review aims to discuss the strategies for switching antipsychotic medications and the impact on metabolic abnormalities in patients with schizophrenia.

Abstract
The prevalence of metabolic syndrome (MetS) in schizophrenia patients is increasing worldwide. The aim of the current study was to examine the progress of MetS in a schizophrenia cohort we had previously investigated and determine the role of various related factors, including sociodemographic and clinical variables, nutritional status and physical activity. Of the 319 patients investigated in the first study, 149 patients agreed to be included in the follow-up. Physical measurements and laboratory tests were performed in addition to evaluations with the Positive and Negative Syndrome Scale, Udvalg for Kliniske Undersogelser Side Effects Scale, International Physical Activity Questionnaire, 24 h dietary recall method and Nutrition Information Systems Package Program. According to the ATPIII, ATPIIIA and IDF criteria, the MetS prevalences had increased from 35.6 to 44.3%, 38.9 to 53% and 43.6 to 55.7%, respectively. Patients with MetS had a shorter period of hospitalization and a higher UKU total side effects score, and most of them were married or divorced/widowed. Patients with MetS also had a higher daily consumption of added sugar, cholesterol, polyunsaturated fatty acids and omega 3 fatty acid, and the daily added sugar intake was found to be related to the increase in MetS. Unexpectedly, the physical activity level was not found to significantly differ in the patients with and without MetS. In conclusion, the MetS prevalence was found to be increased among schizophrenia patients over time, and the increase in the young age group was particularly striking. Among all of the factors investigated, nutritional status was found to play a major role in this increased prevalence.

Prevalence and Associated Factors of Metabolic Syndrome among Patients with Severe Mental Illness Attending a Tertiary Hospital in Southwest Uganda. BIOMED RESEARCH INTERNATIONAL 2019; 2019:1096201. [PMID: 31815121 PMCID: PMC6877961 DOI: 10.1155/2019/1096201] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 07/04/2019] [Accepted: 09/19/2019] [Indexed: 12/14/2022]
Abstract
Globally, the prevalence of metabolic syndrome (MetS) and its components which are the major cardiovascular disease (CVD) risk factors, is higher among patients with severe mental illness (SMI) compared to the general population. This is mainly due to the deleterious lifestyles characterized by physical inactivity, excessive alcohol consumption, smoking, and unhealthy diets common among patients with SMI as well as due to cardiometabolic effects of psychotropic medications. Despite these conditions being highly prevalent among patients with SMI, little attention is given to these conditions during routine reviews in the mental health clinics in most low-income countries including Uganda. The main objective of this study was to determine the prevalence and associated factors of MetS among patients with SMI at Mbarara Regional Referral Hospital (MRRH), a tertiary hospital in southwestern Uganda. Through a cross-sectional study at the mental health clinic of the hospital, we recruited 304 patients with SMI and evaluated them for MetS using the National Cholesterol Education Programme Adult Treatment Panel III (NCEP ATP III) criteria. We defined the prevalence of MetS as the proportion of patients meeting the NCEP ATP III criteria. We used logistic regression to evaluate associations between MetS and independent variables. We included a total of 302 (44.37% male, 55.63% female) patients with a diagnosis of SMI in the analysis. The prevalence of MetS was 23.51% (95% CI 18.84–28.71). At multivariable logistic regression, age >40 years and long duration of mental illness (>10 years) were significantly associated with MetS. The prevalence of MetS is high among patients with psychiatric disorders, and thus metabolic screening, especially among the high-risk groups, is critical.

Abstract
OBJECTIVE Second-generation antipsychotics (SGAs) increase the risk of metabolic syndrome (MetS). Despite the risk of MetS, SGAs may have to be continued with change in some patients. The aim of this study was to trace the evolution of MetS in these patients. METHODS Patients with schizophrenia who had been maintained on a fixed SGA regimen for more than a year were followed-up without changing the regimen. Metabolic indicators were evaluated at baseline and at follow-up. Prevalence, incidence and spontaneous normalization rate of MetS were estimated. Risk factors that might have influenced the evolution were scrutinized. RESULTS A total of 151 subjects were included. During the mean observation period of 389.9±162.4 days, the prevalence of MetS was increased from 35.1 to 45.0%. The incidence rate was 29.6%, while the normalization rate was 26.4%, risk factors affecting incidence were age (OR=1.09, 95% CI: 1.03-1.17), baseline continuous values of metabolic syndrome risk scores (cMetS, OR=1.77, 95% CI:1.29-2.55) and baseline body weight (OR=1.06, 95% CI: 1.01-1.13). Normalization was influenced by age (OR=0.74, 95% CI: 0.57-0.89) and baseline body weight (OR=0.85, 95% CI: 0.72-0.95). CONCLUSION The prevalence of MetS steadily increased with the continuous use of SGAs. However, individual difference was extensive and about a quarter of the patients were able to recover naturally without specific measurements.

Abstract
OBJECTIVE Single nucleotide polymorphisms in serotonin 2C receptor (HTR2C), leptin (LEP), and leptin receptor (LEPR) genes are reportedly associated with the presence of metabolic syndrome (MS). We investigated whether HTR2C:rs518147 (-697G/C), rs12836771 (A/G), LEP: rs7799039 (-2548G/A) and LEPR:rs1137101 (668A/G) are related to MS in psychotic disorder patients treated with atypical antipsychotics. METHODS A cross-sectional study including 200 patients was conducted; genetic polymorphisms in HTR2C (rs518147 and rs12836771), LEP (rs7799039) and LEPR (rs1137101) were genotyped. The presence of MS was evaluated according to the 2005 International Diabetes Federation (IDF) Asia criteria. The associations of genetic factors with the presence of MS are analysed. KEY FINDINGS Two SNPs in the HTR2C gene but not LEP and LEPR were associated with the presence of MS after adjustment for the combination of atypical antipsychotics. With respect to the effect of gender after treatment with risperidone and clozapine was statistically significant. Moreover, genotype combinations had no effect on MS. CONCLUSIONS Therefore, HTR2C genetic variants may be involved in the susceptibility to MS in patients treated with atypical antipsychotics. Additionally, there was a gender effect in the presence of MS. No effect of LEP or LEPR polymorphisms or the combination of HTR2C-LEP and HTR2C-LEPR was observed for the presence of MS.

Abstract
Metabolic syndrome (MetS) is highly prevalent in schizophrenia. However very little is known about the time course of MetS and its components. The few longitudinal studies that have been carried out had small sample sizes and a short follow-up. The aim of our study was to evaluate the prevalence of MetS and its components, at baseline and one year later, and to investigate predictors of weight gain (WG) in a cohort of individuals with schizophrenia. We followed 167 schizophrenia patients from the FACE-SZ cohort for one year. The Structured Clinical Interview for DSM-IV (SCID) was used to confirm the diagnosis of schizophrenia. Data on socio-demographic and clinical characteristics, antipsychotic treatment, and comorbidities were collected, and a blood sample was drawn. We found that the prevalence of MetS increased from 21.0% to 26.6% after one year. Patients with baseline depressive symptoms had a 4.5-fold higher risk of WG at the one-year follow-up (p = 0.02) than those without depressive symptoms, after adjusting for confounding variables. WG also correlated with high levels of metabolic parameters and peripheral inflammation. These findings highlight the need to systematically diagnose depression in Schizophrenia. Future studies should determine whether specific pharmacological and non-pharmacological interventions for depression in SZ subjects are effective in preventing rapid high weight gain.

Prevalence of Metabolic Syndrome in Patients with Schizophrenia in Korea: A Multicenter Nationwide Cross-Sectional Study. Psychiatry Investig 2017; 14:44-50. [PMID: 28096874 PMCID: PMC5240463 DOI: 10.4306/pi.2017.14.1.44] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2016] [Revised: 05/02/2016] [Accepted: 06/03/2016] [Indexed: 12/19/2022] Open
Abstract
OBJECTIVE We designed a nationwide study with limited exclusion criteria to investigate the prevalence of metabolic syndrome (MetS) in Korea and its relationship with antipsychotic medications. METHODS This multicenter, cross-sectional, and observational study included patients diagnosed with schizophrenia or schizoaffective disorder. Sixteen hospitals enrolled 845 patients aged 18 to 65 years prescribed any antipsychotic medication between August 2011 and August 2013. MetS was diagnosed using the criteria of the modified Adult Treatment Panel III of the National Cholesterol Education Program with the Korean abdominal obesity definition (waist circumference ≥85 cm in women, ≥90 cm in men). RESULTS The prevalence of MetS in all patients was 36.5% and was significantly higher in men than women (men, 40.8%; women, 32.2%) and was significantly correlated with age [odds ratio (OR) 1.02] and duration of illness (OR 1.03). The prevalence of MetS across antipsychotic drugs in the major monotherapy group was as follows: 18.8% for quetiapine, 22.0% for aripiprazole, 33.3% for both amisulpride and paliperidone, 34.0% for olanzapine, 35% for risperidone, 39.4% for haloperidol, and 44.7% for clozapine. CONCLUSION The prevalence of MetS is very high in patients with schizophrenia or schizoaffective disorder. Screening and monitoring of MetS is also strongly recommended.

Recommendations for the optimal care of patients with recent-onset psychosis in the Asia-Pacific region. Asia Pac Psychiatry 2016; 8:154-71. [PMID: 27062665 PMCID: PMC4834614 DOI: 10.1111/appy.12234] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2015] [Accepted: 12/29/2015] [Indexed: 12/31/2022]
Abstract
Providing optimal care to patients with recent-onset psychosis can improve outcomes and reduce relapse. However, there is a lack of consistency of the implementation of guidelines for such patients across the Asia-Pacific region. We determined a pragmatic set of recommendations for use on a day-to-day basis to help provide optimal care at this crucial stage of illness. The recommendations were developed over a series of meetings by an international faculty of 15 experts from the Asia-Pacific region, Europe, and South Africa. A structured search of the PubMed database was conducted. This was further developed based on the faculty's clinical experience and knowledge of the literature into 10 key aspects of optimal care for patients during the first five years of a diagnosis of a psychotic disorder, with particular relevance to the Asia-Pacific region. Several common principles emerged: adherence to antipsychotic medications is crucial; substance abuse, psychiatric and medical comorbidities should be addressed; psychosocial interventions play a pivotal role; and family members can play a vital role in overall patient care. By following these recommendations, clinicians may improve outcomes for patients with recent-onset psychosis.

Abstract
Background: Metabolic syndrome is commonly associated with cardiovascular diseases and psychiatric mental illness. Hence, we aimed to assess the metabolic syndrome among severe mental illness (SMI). Materials and Methods: The study included 267 patients who were referred to the psychiatric unit at 5th Azar Education Hospital of Golestan University of Medical Sciences in Gorgan, Iran. Results: The mean waist circumference, systolic and diastolic blood pressure, triglyceride and fasting blood glucose levels were significantly higher in the SMI with metabolic syndrome, but the high density lipoprotein (HDL)-cholesterol was significantly lower. The prevalence of metabolic syndrome in SMI patients was 20.60%. There were significant differences in the mean of waist circumference, systolic (except for women) and diastolic blood pressure, triglyceride, HDL-cholesterol and fasting blood glucose in men and women with metabolic syndrome when compared with subjects without metabolic syndrome. The prevalence of metabolic syndrome in SMI women was higher than men. The most age distribution was in range of 30-39 years old. The most prevalence of metabolic syndrome was in age groups 50-59 years old. The prevalence of metabolic syndrome was increased from 30 to 59 years old. Conclusion: The prevalence of metabolic syndrome in patients with SMI in Gorgan is almost similar to those observed in Asian countries. The prevalence of metabolic syndrome was lower than western countries. These observations may be due to cultural differences in the region. It should be mention that the families of mental illness subjects in our country believe that their patients must be cared better than people without mental illness. These findings of this study suggest that mental illness patients are at risk of metabolic syndrome. According to our results, risk factors such as age and gender differences may play an important role in the presence of metabolic syndrome. In our country, women do less physical activity than men; therefore, the incidence of metabolic syndrome is higher among women.

Abstract
Background There is a surge of cardiovascular disease (CVD) in Africa. CVD is the leading cause of mortality among patients with severe mental illness (SMI) in developed countries, with little evidence from the African context. Objective To determine the prevalence and risk factors for MetS among South African patients with SMI. Method In a cross sectional study, individuals with SMI treated with antipsychotics and a control group without a mental illness, matched for age, gender and ethnicity were evaluated for MetS using the 2009 Joint Interim statement (JIS) criteria. Results Of the 276 study group subjects, 65.9% were male, 84.1% black African, 9.1% white, 5.4% of Indian descent and 1.5% coloured (mixed race) with a mean age of 34.7 years (±12.5). Schizophrenia was the most common diagnosis (73.2%) and 40% were taking first generation antipsychotics. The prevalence of MetS was 23.2% (M: 15.4%, F: 38.3%) in the study group and 19.9% (M: 11.9%, F: 36.3%) in the control group (p = 0.4). MetS prevalence was significantly higher in study subjects over 55 years compared to controls (p = 0.03). Increased waist circumference (p< 0.001) and low high density lipoprotein (HDL) cholesterol (p = 0.003) were significantly more prevalent in study subjects compared to controls. In study subjects, risk factors associated with MetS included age (OR: 1.09, 95% CI 1.06–1.12, p < 0.001), female gender (OR: 2.19, 95% CI 1.06–4.55, p = 0.035) and Indian descent (OR: 5.84, 95% CI 1.66–20.52, p = 0.006) but not class of antipsychotic (p = 0.26). Conclusion The overall MetS prevalence was not increased in patients with SMI compared to controls; however, the higher prevalence of the individual components (HDL cholesterol and waist circumference) suggests an increased risk for CVD, especially in patients over 55 years.

Abstract
OBJECTIVES The use of atypical antipsychotic drugs in patients with psychiatric illness may result in dyslipidemia, hypertension, glucose intolerance, and abdominal obesity, which are together referred to as metabolic syndrome (MS). To investigate any correlations among insulin-like growth factor-1 (IGF-1), schizophrenia, and MS, we examined the metabolic profiles of patients with schizophrenia taking atypical antipsychotics. DESIGN Patients with schizophrenia, their siblings, and controls participated in this study (N=50 in each group). The Structured Clinical Interview for DSM-IV Axis 1 Disorders (SCID I) and the Brief Psychiatric Rating Scale (BPRS) were administered to patients, and SCID I was administered to patients' siblings. We drew blood to measure IGF-1 levels and to determine the metabolic profiles of all participants; we also conducted anthropometric measurements. RESULTS There were no significant differences in IGF-1 levels between groups. By comparing IGF-1 levels with MS-related parameters, we found that IGF-1 levels were negatively correlated with triglyceride levels in the control group, and positively correlated with HDL levels in the patient group (Pearson's correlation: r=-0.291, P=0.04, and r=0.328, P=0.02, respectively). Compared to their siblings, patients with schizophrenia had a significantly different body mass index, waist circumference, and insulin resistance, and showed a trend toward a difference in glucose levels (ANOVA: P=0.004, P<0.0001, P=0.004, P=0.072, respectively). CONCLUSION A correlation between IGF-1 and MS may significantly influence future therapeutic strategies for MS. In order to determine the role of IGF-1 in schizophrenia, comprehensive longitudinal studies with first-episode drug-naive patients are needed.

Abstract
A meta-analysis was conducted to explore the risk for cardio-metabolic abnormalities in drug naïve, first-episode and multi-episode patients with schizophrenia and age- and gender- or cohort-matched general population controls. Our literature search generated 203 relevant studies, of which 136 were included. The final dataset comprised 185,606 unique patients with schizophrenia, and 28 studies provided data for age- and gender-matched or cohort-matched general population controls (n=3,898,739). We found that multi-episode patients with schizophrenia were at increased risk for abdominal obesity (OR=4.43; CI=2.52-7.82; p<0.001), hypertension (OR=1.36; CI=1.21-1.53; p<0.001), low high-density lipoprotein cholesterol (OR=2.35; CI=1.78-3.10; p<0.001), hypertriglyceridemia (OR=2.73; CI=1.95-3.83; p<0.001), metabolic syndrome (OR=2.35; CI=1.68-3.29; p<0.001), and diabetes (OR=1.99; CI=1.55-2.54; p<0.001), compared to controls. Multi-episode patients with schizophrenia were also at increased risk, compared to first-episode (p<0.001) and drug-naïve (p<0.001) patients, for the above abnormalities, with the exception of hypertension and diabetes. Our data provide further evidence supporting WPA recommendations on screening, follow-up, health education and lifestyle changes in people with schizophrenia.

Abstract
Metabolic syndrome (MetS) has been recognized as a risk factor for cardiovascular morbidity and mortality in general population and in patients with severe mental illnesses like schizophrenia. This paper reviews studies on MetS in schizophrenia and related psychotic disorders, and assesses the contribution of antipsychotics toward the development of MetS. Databases of Medline (PubMed), PsycINFO, and Scopus were searched for MetS, psychotic disorders, and antipsychotic drugs from inception till present. Prevalence of MetS in patients with schizophrenia was found to be ranging from 3.3% to 68.0%. Prevalence in antipsychotic-naïve and antipsychotic-treated patients ranged between 3.3-26.0% and 32.0-68.0% respectively, and was higher in younger patients, female gender and Hispanics, and lower in African-Americans and Orientals. Prevalence of metabolic abnormalities was higher in patients receiving second generation antipsychotics (SGAs), especially with clozapine, olanzapine, and risperidone, as compared to first generation antipsychotics (FGAs). Antipsychotic-induced changes on metabolic indices became evident after 2 weeks and reached maximum at 3 months of treatment. There is a need to sensitize the mental health professionals at all levels about the need of screening and monitoring for MetS in patients receiving antipsychotics.

Abstract
To review the data with respect to prevalence of metabolic syndrome (MetS) and its correlates in schizophrenia. For this review, electronic search engines PUBMED, Sciencedirect, and Google Scholar were used. Available data suggests that most of the studies have been of cross-sectional design. Prevalence rates of MetS have varied from 11% to 69% in medicated patients, and 4-26% in drug naive patients in cross-sectional evaluations. Longitudinal studies have shown the prevalence rates to range from 0% to 14% at the baseline in drug naive patients, which increase to as high as 52.4% by 3 months of antipsychotic medication treatment. The prevalence rates of MetS in patients with schizophrenia are much higher than that seen in general population or healthy controls. Though there is no causal association with any demographic or clinical variables, the risk increases with increase in age. Among antipsychotics, there seems to be an association between MetS and atypical antipsychotics like clozapine and olanzapine. Therefore, the psychiatrists should be more vigilant regarding the presence of MetS in these high risk groups. Research on biological correlates of MetS in schizophrenia is still in its primitive stage, however, these is some evidence to suggest an association of MetS with adiponectin levels, hematological indices, methylenetetrahydrofolate reductase (MTHFR) and Alpha-1A adrenergic receptor (ADRA1A) gene. These areas hold promise, and targeting these with appropriate interventions may help us to prevent the occurrence of MetS in patients with schizophrenia in future.

Abstract
OBJECTIVE The aim of the study was to determine the prevalence of cardiometabolic dysregulations and their somatic treatment regimens in a group of psychiatric patients treated with antipsychotics. METHODS In a naturalistic cohort study, baseline cardiometabolic parameters were measured in 543 outpatients. After one year, a second assessment was performed in 220 patients out of the total sample. In addition, it was investigated whether in patients with somatic comorbidities adequate treatment was prescribed. RESULTS In this cohort, about half of the patients fulfilled the criteria for metabolic syndrome. Only a limited number of patients, however, received pharmacologic treatment for individual risk factors: About 19% for hypercholesterolemia, 26% for hypertension, and 52% for diabetes. Non-treated patients were significantly younger than treated patients. Follow-up data show that the course of the cardiometabolic parameters can be dynamic. CONCLUSIONS Cardiometabolic risk factors are highly prevalent in psychiatric patients treated with antipsychotic drugs. Unfortunately, adequate treatment of cardiometabolic comorbidity in these relatively young patients is seriously hampered. Thus, specific guidelines for psychiatric patients have to be developed taking into account the high cardiovascular risk at a relatively young age and potential pharmacokinetic interactions between psychotropics and somatic compounds. Moreover, integration of psychiatric and physical health care systems for patients with mental disorders is urgently needed.

Abstract
BACKGROUND Patients with severe mental illness are at increased risk of developing metabolic disorders. The risk of metabolic syndrome in the Hong Kong general population is lower than that observed in western countries; however the prevalence of metabolic syndrome in patients with severe mental illness in Hong Kong is unknown. METHOD This cross-sectional study aimed to estimate the prevalence of metabolic syndrome in patients with severe mental illness in Hong Kong and to identify the relationships between metabolic syndrome and socio-demographic, clinical and lifestyle factors. RESULTS A total of 139 patients with a diagnosis of severe mental illness participated in the study. The unadjusted prevalence of metabolic syndrome was 35%. The relative risk of metabolic syndrome in comparison with the general Hong Kong population was 2.008 (95% CI 1.59-2.53, p < 0.001). In a logistic regression model sleep disruption and being prescribed first generation antipsychotics were significantly associated with the syndrome, whilst eating less than 3 portions of fruit/vegetables per day and being married were weakly associated. CONCLUSION The results demonstrate that metabolic syndrome is highly prevalent and that physical health inequalities in patients with severe mental illness in Hong Kong are similar to those observed in western countries. The results provide sufficient evidence to support the need for intervention studies in this setting and reinforce the requirement to conduct regular physical health checks for all patients with severe mental illness.

Abstract
AIMS The main aims of the study were to investigate the prevalence of pre-diabetes and diabetes mellitus (DM) in patients with schizophrenia, to compare it with those published in the general population, and to assess significant associations with dysglycemia defined as having either pre-DM or DM. METHODS A cross-sectional study carried out in 4 governmental primary psychiatric healthcare centers in Northern West-Bank, Palestine. Fasting blood glucose (FBG) and glycated hemoglobin (HbA1c) were measured. The World Health Organization (WHO) criteria for defining pre-DM and DM were used. Dysglycemia was defined as FBG >110mg/dl. RESULTS Based on WHO criteria, 27 patients (10.8%) had diabetes and 34 (13.6%) had pre-diabetes. The prevalence of DM in patients with schizophrenia was not significantly higher than that reported in the general population of Palestine. However, the prevalence of pre-DM was significantly higher than that reported in the general population of Palestine. Regression analysis showed that advancing age and abnormal waist circumference were significant predictors of dysglycemia in patients with schizophrenia. CONCLUSIONS This study confirmed the high prevalence of dysglycemia in patients with schizophrenia, supporting the need for monitoring of blood glucose in this category of patients. The presence of primary risk factors is more important in the development of dysglycemia in patients with schizophrenia than exposure to antipsychotic drugs.

Abstract
Metabolic syndrome (MetS), a constellation of central obesity, hypertension, dyslipidaemia and glucose intolerance, is highly prevalent in individuals with schizophrenia and conveys significant cardiovascular risk and mortality. Associated risk factors are female sex, some ethnic groups, advanced age, long duration of illness, smoking and exposure to antipsychotic agents. The prevalence of MetS varies across countries and psychiatric populations, and its development can be very rapid. Regular monitoring of all features of MetS is the cornerstone of its early detection and management. Future research needs to focus more on genetic determinants of MetS in the context of schizophrenic illness. This review aims to update the reader with the latest knowledge about the prevalence of MetS in schizophrenia and what might be the underlying pathophysiological mechanisms.

Abstract
PURPOSE To identify the point prevalence of metabolic syndrome in patients with schizophrenia and to evaluate the association between depressive symptoms and metabolic syndrome in patients with schizophrenia. PATIENTS AND METHODS Metabolic syndrome was assessed based on an updated definition derived from the modified National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) and the International Diabetes Federation criteria. The 17-item Hamilton Depression Rating Scale (HDRS-17) was used to measure depressive symptoms in 80 patients with schizophrenia. Odds ratios and 95% confidence intervals were calculated using logistic regression for the association between each depressive symptom and metabolic syndrome. RESULTS The point prevalence rates of metabolic syndrome according to the modified NCEP-ATP III and International Diabetes Federation criteria were 37% and 35%, respectively. The risk of having metabolic syndrome significantly increased in those who were widowed or separated, or had longer duration of illness. Central obesity was the metabolic feature with the highest odds ratios for metabolic syndrome at 19.3. Three out of 17 items of HDRS subscales were found to be significantly associated with metabolic syndrome, including depressed mood, middle insomnia, and retardation with the odds ratios of 3.0, 3.4, and 3.6, respectively. CONCLUSION This study showed that the prevalence of metabolic syndrome in patients with schizophrenia was higher than the overall rate but was slightly lower than in the general population in the USA. Central obesity, measured by waist circumference, was found to be highly correlated with metabolic syndrome. Depressed mood, middle insomnia, and retardation were significantly associated with metabolic syndrome in patients with schizophrenia. Waist circumference and screening for depression should be done at the clinics during patient follow-up.

Abstract
Women and children with psychotic disorders in developing countries may be vulnerable and have considerable social disadvantages. Gender disadvantage has implications for all health outcomes including mental illnesses. In the more relevant gender-related context we discuss several important issues which affect women with schizophrenia, namely stigma, caregiver burden, functional outcome, marriage, victimization and help-seeking. The findings indicate that there are variations in clinical and functional outcomes and age of onset of illness between different regions. Drug side effects, such as metabolic syndrome appear to be quite common, adding to disease burden in women from developing countries. Victimization and coercion may contribute to poor quality of life and health concerns such as STIs and HIV. Stigma among women with schizophrenia appears to play a major role in help-seeking, caregiver burden and issues such as marriage and parenting. Gender-sensitive care and practices are few and not well documented. Research in the area of psychoses in children and adolescents from LAMI countries is sparse and is mainly restricted to a few clinic-based studies. More research is needed on organic and medical factors contributing to childhood psychoses, pathways to care, help-seeking, and impact of early detection and community care.

Abstract
AIM The article aims to study the prevalence of metabolic syndrome (MS) and subthreshold MS in antipsychotic naïve patients with schizophrenia. MATERIALS AND METHODS Forty-six antipsychotic naïve patients diagnosed with schizophrenia were evaluated for the presence of metabolic abnormalities using International Diabetes Federation and modified National Cholesterol Education Program-Third Adult Treatment Panel criteria. RESULTS Five patients (10.86%) fulfilled International Diabetes Federation criteria for MS and six patients (13.04%) met modified National Cholesterol Education Program-Third Adult Treatment Panel criteria for MS. Additionally, 14 (30.43%) more patients fulfilled 2 out of the 5 criteria for MS and another 19 (41.3%) fulfilled 1 criterion for MS. Of the 19 patients who fulfilled one criterion for MS, 18 had an abnormality other than increase in waist circumference. CONCLUSION Findings of the present study suggest that although only few antipsychotic naïve patients diagnosed with schizophrenia have MS, a significantly large proportion of patients have subsyndromal MS. Awareness of this in clinicians can have implications in the selection of antipsychotic medication.

Abstract
Second-generation antipsychotics (SGAs) increase the risk of metabolic syndrome (MetS). Although ethnicity also contributes to MetS risk, the majority of the studies on the relationship of SGAs to this syndrome come from Western countries, whereas few reports have come from Asian countries, especially regarding patients taking a single SGA. We reviewed the electronic medical records of patients with schizophrenia who received aripiprazole, olanzapine or risperidone monotherapies for at least three months. We evaluated the prevalence of MetS in our sample as well as the indirect standardized prevalence ratio (ISPR) using data from the 4th Korean National Health and Nutrition Examination Survey (KNHNES, 2007). The prevalence of MetS in our sample (n=145) was 31.7%, and the ISPR was 2.09. Male patients had a higher prevalence of MetS than female patients (odds ratio [OR]=4.18, 95% CI=1.93-9.03). The ISPR of male patients was 2.67 and statistically significant, whereas the ISPR of female patients was not significant. In our sample, the frequency of abnormal MetS subcomponents occurred in descending order: increased waist circumference, increased triglyceride levels, decreased HDL-cholesterol levels, elevated blood pressure and elevated fasting blood glucose levels. Patients who received aripiprazole were significantly less likely to have MetS. However, a logistic regression showed that age and sex, but not the type of antipsychotic, its dose or the use of antidepressants, were significantly related to the presence of MetS. There were no statistically significant differences among SGAs in terms of MetS subcomponent abnormalities of after adjusting for age and sex. In conclusion, only male Korean patients with schizophrenia who received a monotherapy of aripiprazole, olanzapine or risperidone for more than three months were more likely to have MetS than the general population.

Abstract
Schizophrenia is a psychiatric disorder characterized by heterogeneous symptoms, affecting 0.8-1% of the population worldwide. It usually begins in early adulthood and demonstrates a chronic course. In recent years research interest has turned to the increased burden of somatic illness in schizophrenia, with special emphasis on metabolic syndrome and diabetes. In this article I review the theoretical and practical aspects of the comorbidity of schizophrenia with metabolic syndrome and diabetes mellitus. Epidemiological studies demonstrate the occurrence of metabolic syndrome between 22% and 66%, while the prevalence of diabetes is at least threefold compared to the non-psychiatric population in all age groups. Etiologically it is not clear to what extent these alterations are caused by direct genetic and biological effects in contrast to environmental factors. Among the latter the role of atypical antipsychotics should be emphasized. Clinical management of prediabetic conditions and diabetes in schizophrenia warrants the close cooperation of professionals working in the areas of psychiatry and diabetology. This cooperation should include close metabolic monitoring, lifestyle and dietary training, moreover careful modification and in some cases switching of antipsychotic medication. Persisting metabolic symptoms or diabetes require treatment with oral antidiabetics, fibrates, and statins.

Abstract
The lifespan of people with severe mental illness (SMI) is shorter compared to the general population. This excess mortality is mainly due to physical illness. We report prevalence rates of different physical illnesses as well as important individual lifestyle choices, side effects of psychotropic treatment and disparities in health care access, utilization and provision that contribute to these poor physical health outcomes. We searched MEDLINE (1966 - August 2010) combining the MeSH terms of schizophrenia, bipolar disorder and major depressive disorder with the different MeSH terms of general physical disease categories to select pertinent reviews and additional relevant studies through cross-referencing to identify prevalence figures and factors contributing to the excess morbidity and mortality rates. Nutritional and metabolic diseases, cardiovascular diseases, viral diseases, respiratory tract diseases, musculoskeletal diseases, sexual dysfunction, pregnancy complications, stomatognathic diseases, and possibly obesity-related cancers are, compared to the general population, more prevalent among people with SMI. It seems that lifestyle as well as treatment specific factors account for much of the increased risk for most of these physical diseases. Moreover, there is sufficient evidence that people with SMI are less likely to receive standard levels of care for most of these diseases. Lifestyle factors, relatively easy to measure, are barely considered for screening; baseline testing of numerous important physical parameters is insufficiently performed. Besides modifiable lifestyle factors and side effects of psychotropic medications, access to and quality of health care remains to be improved for individuals with SMI.

Abstract
Most studies point to an increased prevalence of metabolic syndrome (MS) and an increased risk of coronary heart disease (CHD) in schizophrenia patients with MS. The aims of this study were to compare the prevalence of MS in schizophrenia patients with the general population, to explore the clinical correlates and predictors of MS and to evaluate the risk for CHD within 10 years. Consecutive 319 patients, aged 18-75 years, with a diagnosis of schizophrenia according to the DSM-IV were enrolled. The ATP-III, the ATP-IIIA and the IDF criteria were used to define MS. 10-year risk of CHD events was calculated with the Framingham score. One hundred nine (34.2%) patients met the ATP-III criteria, 118 (37%) the ATP-IIIA and 133 (41.7%) the IDF criteria for MS. Patients with MS were older, had a later onset of illness and an older age at first hospitalization. The prevalence of MS in schizophrenia patients was higher from the general population only within the 20-29 age group. Patients with MS had a higher age and sex-corrected 10-year risk of CHD events. The only predictor of MS was the age of illness onset. In conclusion, countries where the general population prevalence of MS is already too high, schizophrenia patients younger than 30 years of age might be under higher risk of morbidity and mortality related with MS. This study points to the necessity for aggressive interventions to correct MS in schizophrenia as early as possible, within the first 10 years of post detection.

Abstract
OBJECTIVE The aim of this study was to identify the prevalence of metabolic syndrome and its putative precursors in a naturalistic study of non-acute inpatients at a psychiatric hospital. METHOD Anthropometric and biochemical data collected from the hospital's annual cardiometabolic survey, along with information about prescribed medications, were used to assess the prevalence and predictors of physical health problems in patients with schizophrenia. RESULTS Of the 167 patients included in the survey, 52.4% met criteria for metabolic syndrome. A shorter duration of hospital admission and clozapine use were significant predictors of metabolic syndrome. Age, gender, duration of admission and clozapine use were all predictors of individual cardiometabolic risk factors. CONCLUSIONS The findings from this naturalistic study reinforce the high prevalence of physical health problems in patients with schizophrenia and the important influence that psychiatric treatments can have on physical health. The impact of clozapine on cardiometabolic health appears to occur early in the course of treatment and emphasizes the need for proactive monitoring and interventions from the outset of management.

Abstract
Schizophrenia patients have high prevalence of cardiovascular (CV) disease risk factors and high CV mortality, with increasing concern over the contribution of antipsychotic medications to cardiometabolic risk. The design of the NIMH-sponsored Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) Schizophrenia Trial was driven by a need to understand the efficacy and safety differences between atypical antipsychotics, and between atypical and typical antipsychotics. The CATIE data indicated differences between olanzapine and other antipsychotics in phase 1 on the primary outcome measure, time to drug discontinuation, yet olanzapine was not superior to risperidone in the phase 2 tolerability arm, and was inferior to clozapine in the phase 2 efficacy arm. However, CATIE provided clear confirmation of the metabolic liability for olanzapine and also quetiapine, particularly on measures associated with insulin resistance: fasting triglycerides and central adiposity. Current research is focused on analyzing the adiposity-independent impact of certain antipsychotics on glucose-insulin homeostasis, and the disease-specific biological factors that predispose schizophrenia patients to metabolic dysfunction. The CATIE data also highlighte the high prevalence of metabolic disorders in chronic schizophrenia patients, and the moderating role of gender and race or ethnicity in antipsychotic-associate metabolic adverse effects. In the post-CATIE era, safety concerns remain the primary driver of antipsychotic prescribing habits. Absent compelling efficacy data that differentiates between antipsychotics for nonrefractory schizophrenia, the CATIE results reinforce the need for additional metabolically neutral antipsy chotic treatment options, and the importance of ongoing physical health monitorin for schizophrenia patients.

Abstract
Sex differences observed in the adverse effects associated with psychotropic drugs have not been reported consistently in the literature. In this review, we discuss the current published data on sex differences observed in the occurrence, symptomatology and reporting of the adverse effects associated with psychotropic drug effects, and discuss their clinical relevance. We reviewed the published data up to April 2009 on sex differences in the side effects of antipsychotics, antidepressant and mood stabilizers, by systematically searching PubMed using combinations of search terms and retrieving relevant references specifically reporting on these issues. The majority of the data was retrieved from clinical studies where the main outcome parameters did not relate specifically to sex differences. In most instances, sex was associated with other factors influencing side effects such as age, disease and body weight. Sex-related differences were reported in the side effects associated with antipsychotic drug-induced weight gain and metabolic syndrome, symptoms of sexual dysfunction caused by antidepressants and antipsychotic drugs and cardiac arrhythmic side effects associated with antipsychotic drugs. Women might differ from men not only in incidence but also in the presentation of clinical symptoms associated with adverse psychotropic drug effects. Clinicians should be made aware of the differences reported in the literature regarding the symptomatology, severity and recognition of the adverse psychotropic drug effects found in men and women.

Abstract
Cross-sectional studies showed a high prevalence of metabolic syndrome in patients with schizophrenia.This study aimed to identify the incidence of metabolic syndrome and its reversal in a non-preselected cohort of chronic psychotic patients in routine practice in one year follow-up and to find variables to describe development and reversal of metabolic syndrome. This cohort study was conducted as part of a disease management program and patients were included if they had two complete assessments in a one year follow-up. We conducted two logistic regressions to find variables to describe the development of metabolic syndrome and the reversal of metabolic syndrome. At the time of the first assessment 35% (n=92) of the 260 included patients had metabolic syndrome. Within one year 21 patients developed metabolic syndrome and 30 patients had it reversed. This was an incidence of 13% (21/168) and a reversal of 33% (30/92). Smoking, family history of cardiovascular diseases, and duration of disease >6 years was associated with a higher risk of developing metabolic syndrome as well as abdominal obesity and dyslipidemia. Patients with abdominal obesity had a smaller chance of reversing metabolic syndrome. Other variables included in the logistic regression such as receiving cardiovascular/antidiabetic drug treatment or duration of disease >6 years did not alter the risk of reversing the metabolic syndrome. Our study showed that the natural course of metabolic syndrome is dynamic. A considerable number of patients developed or reversed the metabolic syndrome in one year follow-up.

Abstract
INTRODUCTION Having a mental illness has been and remains even now, a strong barrier to effective medical care. Most mental illness, such as schizophrenia, bipolar disorder, and depression are associated with undue medical morbidity and mortality. It represents a major health problem, with a 15 to 30 year shorter lifetime compared with the general population. METHODS Based these facts, a workshop was convened by a panel of specialists: psychiatrists, endocrinologists, cardiologists, internists, and pharmacologists from some French hospitals to review the information relating to the comorbidity and mortality among the patients with severe mental illness, the risks with antipsychotic treatment for the development of metabolic disorders and finally cardiovascular disease. The French experts strongly agreed on these points: that the patients with severe mental illness have a higher rate of preventable risk factors such as smoking, addiction, poor diet, lack of exercise; the recognition and management of morbidity are made more difficult by barriers related to patients, the illness, the attitudes of medical practitioners, and the structure of healthcare delivery services; and improved detection and treatment of comorbidity medical illness in people with severe mental illness will have significant benefits for their psychosocial functioning and overall quality of life. GUIDELINES FOR INITIATING ANTIPSYCHOTIC THERAPY: Based on these elements, the French experts propose guidelines for practising psychiatrists when initiating and maintaining therapy with antipsychotic compounds. The aim of the guidelines is practical and concerns the detection of medical illness at the first episode of mental illness, management of comorbidity with other specialists, family practitioner and follow-up with some key points. The guidelines are divided into two major parts. The first part provides: a review of mortality and comorbidity of patients with severe mental illness: the increased morbidity and mortality are primarily due to premature cardiovascular disease (myocardial infarction, stroke...).The cardiovascular events are strongly linked to non modifiable risk factors such as age, gender, personal and/or family history, but also to crucial modifiable risk factors, such as overweight and obesity, dyslipidemia, diabetes, hypertension and smoking. Although these classical risk factors exist in the general population, epidemiological studies suggest that patients with severe mental illness have an increased prevalence of these risk factors. The causes of increased metabolic and cardiovascular risk in this population are strongly related to poverty and limited access to medical care, but also to the use of psychotropic medication. A review of major published consensus guidelines for metabolic monitoring of patients treated with antipsychotic medication that have recommended stringent monitoring of metabolic status and cardiovascular risk factors in psychiatric patients receiving antipsychotic drugs. There have been six attempts, all published between 2004 and 2005: Mount Sinai, Australia, ADA-APA, Belgium, United Kingdom, Canada. Each guideline had specific, somewhat discordant, recommendations about which patients and drugs should be monitored. However, there was agreement on the importance of baseline monitoring and follow-up for the first three to four months of treatment, with subsequent ongoing reevaluation. There was agreement on the utility of the following tests and measures: weight and height, waist circumference, blood pressure, fasting plasma glucose, fasting lipid profile. In the second part, the French experts propose guidelines for practising psychiatrists when initiating and maintaining therapy with antipsychotic drugs: the first goal is identification of risk factors for development of metabolic and cardiovascular disorders: non modifiable risk factors: these include: increasing age, gender (increased rates of obesity, diabetes and metabolic syndrome are observed in female patients treated with antipsychotic drugs), personal and family history of obesity, diabetes, heart disease, ethnicity as we know that there are increased rates of diabetes, metabolic syndrome and coronary heart disease in patients of non European ethnicity, especially among South Asian, Hispanic, and Native American people. Modifiable risk factors: these include: obesity, visceral obesity, smoking, physical inactivity, and bad diet habits. Then the expert's panel focussed on all the components of the initial visit such as: family and medical history; baseline weight and BMI should be measured for all patients. Body mass index can be calculated by dividing weight (in kilograms) by height (in meters) squared; visceral obesity measured by waist circumference; blood pressure; fasting plasma glucose; fasting lipid profiles. These are the basic measures and laboratory examinations to do when initiating an antipsychotic treatment. ECG: several of the antipsychotic medications, typical and atypical, have been shown to prolong the QTc interval on the ECG. Prolongation of the QTc interval is of potential concern since the patient may be at risk for wave burst arrhythmia, a potentially serious ventricular arrhythmia. A QTc interval greater than 500 ms places the patient at a significantly increased risk for serious arrhythmia. QTc prolongation has been reported with varying incidence and degrees of severity. The atypical antipsychotics can also cause other cardiovascular adverse effects with, for example, orthostatic hypotension. Risk factors for cardiovascular adverse effects with antipsychotics include: known cardiovascular disease, electrolyte disorders, such as hypokaliemia, hypomagnesaemia, genetic characteristics, increasing age, female gender, autonomic dysfunction, high doses of antipsychotics, the use of interacting drugs, and psychiatric illness itself. In any patient with pre-existing cardiac disease, a pre-treatment ECG with routine follow-up is recommended. CONCLUDING REMARKS Patients on antipsychotic drugs should undergo regular testing of blood sugar, lipid profile, as well as body weight, waist circumference and blood pressure, with recommended time intervals between measures. Clinicians should track the effects of treatment on physical and biological parameters, and should facilitate access to appropriate medical care. In order to prevent or limit possible side effects, information must be given to the patient and his family on the cardiovascular and metabolic risks. The cost-effectiveness of implementing these recommendations is considerable: the costs of laboratory tests and additional equipment costs (such as scales, tape measures, and blood pressure devices) are modest. The issue of responsibility for monitoring for metabolic abnormalities is much debated. However, with the prescription of antipsychotic drugs comes the responsibility for monitoring potential drug-induced metabolic abnormalities. The onset of metabolic disorders will imply specific treatments. A coordinated action of psychiatrists, general practitioners, endocrinologists, cardiologists, nurses, dieticians, and of the family is certainly a key determinant to ensure the optimal care of these patients.

Abstract
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.

Abstract
OBJECTIVE To summarize the accumulated data on metabolic syndrome prevalence in patients with schizophrenia, examine evidence for a biological contribution of the mental illness to metabolic risk and review novel options available for management of prediabetic states. METHOD A Medline search using metabolic syndrome, insulin resistance and insulin sensitivity cross-referenced with schizophrenia was performed on articles published between 1990 and May 2008. RESULTS Recent evidence indicates that schizophrenia increases predisposition towards metabolic dysfunction independent of environmental exposure. Both fasting and non-fasting triglycerides have emerged as important indicators of cardiometabolic risk, while metformin, thiazolidinediones and GLP-1 modulators may prove promising tools for managing insulin resistance. CONCLUSION Because of lifestyle, disease and medication effects, schizophrenia patients have significant risk for cardiometabolic disease. Routine monitoring, preferential use of metabolically neutral antipsychotics and lifestyle education are critical to minimizing risk, with a possible role for antidiabetic medications for management of insulin resistant states that do not respond to other treatment strategies.

Abstract
OBJECTIVE Cardiovascular disease is one of the most prevalent factors responsible for excess mortality in schizophrenia. Metabolic syndrome (MetS) is associated with the development of coronary heart disease and diabetes mellitus. The aim in this cross-sectional study was to assess the prevalence of MetS in schizophrenic Turkish inpatients. METHOD The study was conducted from January 2006 to June 2006, and included 231 patients with schizophrenia. All participants were enrolled from inpatients attending the Samsun Mental Health Hospital psychiatry clinic. All subjects were aged between 18 and 65 and met the DSM IV criteria for schizophrenia. MetS was taken as central obesity (defined as waist circumference: men > or = 94 cm, women > or = 80 cm) and meeting > or = 2 of the following abnormalities described by the International Diabetes Federation (IDF): a serum triglyceride level > 150 mg/dL, high-density lipoprotein (HDL) cholesterol < 40 mg/dL in men and < 50 mg/dL in women, blood pressure > or = 130/85 mm Hg, and a fasting serum glucose level > or = 100 mg/d/L. RESULTS The study group consisted of 174 male and 57 female patients. Mean age was 38.5 +/- 10.5 and mean duration of illness was 15.76 +/- 9.95 years. The overall prevalence of MetS diagnosed according to the IDF criteria was 32.0% (n = 74) and was higher in females (61.4%) than in males (22.4%; p = 0.0001). In logistic regression analysis the last step of the regression model was gender (B = 1.70, p = 0.0001, OR = 5.50, 95% CI = 2.90-10.45). CONCLUSION This study shows that the prevalence of MetS in Turkish patients with schizophrenia is similar to that of the general population, but lower than in other reports regarding the schizophrenia population.

Change in metabolic syndrome parameters with antipsychotic treatment in the CATIE Schizophrenia Trial: prospective data from phase 1. Schizophr Res 2008; 101:273-86. [PMID: 18258416 PMCID: PMC3673564 DOI: 10.1016/j.schres.2007.12.487] [Citation(s) in RCA: 181] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2007] [Revised: 12/06/2007] [Accepted: 12/22/2007] [Indexed: 10/22/2022]
Abstract
BACKGROUND The metabolic syndrome (MS) is associated with increased risk for diabetes mellitus and coronary heart disease, and is highly prevalent among schizophrenia patients. Given concerns over antipsychotic metabolic effects, this analysis explored MS status and outcomes in phase 1 of the CATIE Schizophrenia Trial. METHODS The change in proportion of subjects with MS and individual criteria was compared between antipsychotic treatment groups, along with mean changes for individual criteria. Primary analyses examined subjects with fasting laboratory assessments at baseline and 3 months. Other analyses examined 3-month changes in MS status, waist circumference (WC), HDL cholesterol and blood pressure in all subjects, metabolic changes at the end of phase 1 participation (EOP), and repeated measures changes in HDL, blood pressure (BP) and WC over phase 1. RESULTS At 3 months, there were no significant between-drug differences for the change in proportion of subjects meeting MS status or individual MS criteria in the smaller fasting cohort (n = 281) or for those meeting criteria for parameters not dependent on fasting status (BP, HDL, WC) among all subjects (n=660). Among all subjects whose MS status could be determined at 3 months (n=660), MS prevalence increased for olanzapine (from 34.8% to 43.9%), but decreased for ziprasidone (from 37.7% to 29.9%) (p=.001). Although effect sizes varied across subgroups, at 3 months olanzapine and quetiapine had the largest mean increase in waist circumference (0.7 in. for both) followed by risperidone (0.4 in.), compared to no change for ziprasidone (0.0 in.) and a decrease in waist circumference for perphenazine (-0.4 in.). Olanzapine also demonstrated significantly different changes in fasting triglycerides at 3 months (+21.5 mg/dl) compared to ziprasidone (-32.1 mg/dl). EOP exposure data was obtained, on average, nine months from baseline for all metabolic variables. Results from EOP and repeated measures analyses were consistent with those at 3 months for mean changes in WC and fasting triglycerides, but between group differences emerged for HDL and SBP. CONCLUSIONS This large non-industry sponsored study confirms the differential metabolic effects between antipsychotics. Clinicians are advised to monitor all metabolic parameters, including WC, HDL and serum triglycerides, during antipsychotic treatment.

Typical and atypical antipsychotics differentially affect long-term incidence rates of the metabolic syndrome in first-episode patients with schizophrenia: a retrospective chart review. Schizophr Res 2008; 101:295-303. [PMID: 18299188 DOI: 10.1016/j.schres.2008.01.028] [Citation(s) in RCA: 178] [Impact Index Per Article: 11.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2007] [Revised: 01/22/2008] [Accepted: 01/28/2008] [Indexed: 11/29/2022]
Abstract
UNLABELLED The presence of the metabolic syndrome (MetS) is an important risk factor for cardiovascular disease and diabetes. There are limited data on the prevalence of MetS in patients with schizophrenia at the onset of the disorder and specifically no data on patients treated in the era when only first-generation antipsychotics were available. METHODS Data from a historic cohort of consecutively admitted first-episode patients with schizophrenia treated with first-generation antipsychotics (FGAs) were compared with an age and sex matched series of consecutive first-episode patients treated only with second-generation antipsychotics (SGAs). Rates of MetS were compared at baseline and after on average 3 years of treatment exposure. RESULTS At first episode there was no difference in the prevalence of MetS between the historic and the current cohort. Rates of MetS increased over time in both groups, but patients started on SGAs had a three times higher incidence rate of MetS (Odds Ratio 3.6, CI 1.7-7.5). The average increase in weight and body mass index was twice as high in patients started on SGA. The difference between the FGA and SGA group was no longer significant when patients started on clozapine and olanzapine were excluded. CONCLUSION Rates of MetS at the first episode of schizophrenia today are not different from those of patients 15 to 20 years ago. This finding counters the notion that the high rates of metabolic abnormalities in patients with schizophrenia currently reported are mainly due to lifestyle changes over time in the general population. Some SGAs have a significantly more negative impact on the incidence of MetS compared to FGAs in first-episode patients.
