Background: To review evidence of chronic antipsychotic medication and the association with metabolic syndrome in mentally ill patients. This evidence was used to analyse a cohort of patients with severe mental illness and to deduce a correlation between the prevalence of metabolic syndrome and their dose regimens. Materials and Methods: Twenty-four male patients undergoing Psychiatric rehabilitation underwent a review of current medication and assessment of risk factors for metabolic syndrome. Assessment criteria was based upon National Cholesterol Education Programme expert panel on detection, evaluation and treatment of high blood cholesterol in adults (Adult Treatment Panel III) (NCEP ATP III) criteria, incorporating waist circumference, raised triglycerides, reduced high density lipoprotein, raised blood pressure and fasting blood glucose. PubMed, Nature and Science Direct databases have been used to compile the medical and scientific background on metabolic syndrome and antipsychotic medication and the effect on patients particularly on high dose. Results: Out of 24 patients, 10 patients (41.7%) were receiving high dose antipsychotics (HDA) and four were on maximum dosage limits of 100%. 8.3% (2/24) patients were receiving only one first generation antipsychotics (FGA), 37.5% (9/24) patients were receiving only one second generation antipsychotic (SGA), 45.8% patients (11/24) were receiving two or more SGA only, and only one patient was receiving two or more FGA. One patient was receiving a combination of FGA and SGA. PRN ("as needed") therapy was not included in this study as their usage was limited. Clozapine was mostly prescribed in these patients (10/24, 41.6%). Four out of the 24 patients refused blood tests therefore were excluded from the following results. In the patients evaluated, 55% (11/20) had confirmed metabolic syndrome. In these patients with metabolic syndrome, 45.4% (5/11) were on HDA and 27.3% (3/11) were on maximum British National Formulary (BNF) limits of 100% of dosage. Four out of the nine remaining patients not diagnosed with metabolic syndrome were on HDA. Conclusions: Evidence supports the association between antipsychotic medication and metabolic syndrome. The data extrapolated from this cohort of mentally ill patients demonstrates that there is an increase in risk factors for metabolic syndrome and weight gain in the majority of patients on antipsychotic medication. The data however does not support any further predisposition to metabolic syndrome in these patients taking HDA. It also cannot be assumed antipsychotic medication is independently associated with the prevalence of these abnormalities.
Human Psychopharmacology: Clinical and Experimental, 2012
Objective We evaluated prevalence and risk factors for metabolic syndrome in inpatients treated with antipsychotics, with or without other psychotropic drugs. Although the literature on metabolic syndrome in psychiatry has expanded in recent years, we seek to elucidate some of the remaining gaps by examining a severely and chronically ill population heavily treated with pharmacological agents. Methods With data from medical records of 589 adults hospitalized at McLean Hospital in 2010 and 2011, we used standard statistical analyses to characterize risks and covariates of metabolic syndrome. Results With prior antipsychotic treatment, prevalence of metabolic syndrome was 29.5%. The syndrome was strongly associated with being overweight (≥25 kg/m 2 in 60.1% of subjects), older age, longer treatment-exposure, schizoaffective diagnosis (39.8%), more illness-episodes or hospitalizations, polytherapy, and higher total daily chlorpromazine-equivalent doses, but not sex. Notably, metabolic syndrome risk was greater among young, antipsychotic treated patients (15.5-fold at age ≤25 years). Conclusions The findings extend information on the association of metabolic syndrome with antipsychotic treatment. Metabolic syndrome was found in 30% of antipsychotic-exposed inpatients. Risk was surprisingly high in young persons and after brief treatment-exposure, and psychotropic polytherapy increased risk.
Metabolic Syndrome in Patients with Psychosis Using Second-Generation Antipsychotics
PARIPEX INDIAN JOURNAL OF RESEARCH
Background: Persons with Schizophrenia are more likely to die from cardiovascular illness and are at a greater risk of developing obesity, diabetes mellitus (DM), hypertension (HTN), and dyslipidemias. Though the SGA were quite effective, their safety advantages have been questioned because of their propensity to induce weight gain and alter glucose,lipid metabolism. Objectives: 1.To study the incidence of metabolic syndrome (MS) due to selected SGA 2.To compare any differences in the metabolic profile of patients on various antipsychotics. Methodology: A Study was done for about a year among 120 Drug Naive patients with the diagnosis of schizophrenia or acute psychosis as per ICD 10 criteria,attending psychiatry OPD and were selected by systematic sampling method into four groups.With the Group (A) receiving Olanzapine, group (B) Risperidone, group (C) Quetiapine, group (D) Aripiprazole.Each group consisting of 30 patients.After 12 weeks of medication,Patients were screened for the...

Metabolic abnormalities are common in patients maintained on antipsychotics. These abnormalities increase the risk of cardiovascular diseases and mortality in this population. The aim of this study is to assess the prevalence of metabolic syndrome (MetS) in subjects maintained on antipsychotics relative to controls in Qatar, and to assess the factors contributing to the development of MetS. A cross sectional design was used to collect data and fasting blood samples from subjects maintained on antipsychotics for at least six months (n = 112) and from a control group (n = 114). The groups were compared in regard to prevalence of MetS, and multiple regression analysis was used to determine the risk factors in each group. The two groups (antipsychotics vs. control) were similar in regard to age (35.73 ± 10.28 vs. 35.73 ± 8.16 years) and gender ratio. The MetS was higher among the subjects on antipsychotics, but this difference did not reach statistical significance. Blood pressure (BP) ...

Introduction: The metabolic syndrome (MS) is an area of interest for mental health research because individuals with mental illnesses have an increased risk of medical morbidity and mortality compared with the general population. This cross-sectional study is aimed to estimate the prevalence of metabolic syndrome in an Italian psychiatric sample, treated with different types of antipsychotics. Methods: The data were derived from medical records of patient with affective and non-affective psychosis, admitted to the Hospital of L'Aquila psychiatric ward, from January 2012 to July 2014. The sample refers to consecutive admissions of subjects of both sexes, aged over 18 years, receiving one or more antipsychotic treatment. The diagnosis of MS was established when the clinical subject at least three of the five diagnostic criteria of the Adult Treatment Panel (NCEP-ATP III) were met. Results: 389 subjects were evaluated. We report a MS prevalence of 27.5%. This figure is very close to the metabolic syndrome prevalence in the Italian general population quoted around 26%. The BMI values also are very similar in these two populations, despite a higher obesity rate in the clinical sample. The MS prevalence rates in subject with schizophrenia, bipolar disorders and depressive disorders were respectively 30.6%, 36.4% and 36.8%. No significant differences in MS, diabetes or dyslipidemia rates were found among the three diagnostic groups. We did not find differences in metabolic syndrome prevalence either in relation to psychotropic polypharmacy or in relation to typical or atypical antipsychotics. However the psychiatric females in the clinical sample tend to have higher obesity rate, with a sort of all or none distribution (i.e. more obesity, more normal weight, but less overweight) compared to the general population. Conclusions: These findings could be explained by the interaction of some sort of liability due to drug treatment, illness related lifestyles, gender and other interacting factors (e.g. genetic) with metabolic issues.
Influence of antipsychotics on metabolic syndrome risk in patients with schizophrenia
Frontiers in Psychiatry
ObjectiveMany studies so far have shown that antipsychotic therapy may have an effect on the development of metabolic syndrome in patients diagnosed with schizophrenia. Our goal was to determine whether our respondents are at risk for developing metabolic syndrome and who is more predisposed to it.MethodsIn a stable phase, 60 patients diagnosed with schizophrenia were equally divided into three groups according to the drug (risperidone, clozapine, and aripiprazole monotherapy). Control group had 20 healthy examinees. Patients were evaluated first using The Positive and Negative Syndrome Scale (PANSS). Prolactin, lipid status, glycemia, insulin, cytokine values (IL-33, TGF-β, and TNF-α) and C-reactive protein (CRP) were measured. Also, Body mass index (BMI), Homeostatic Model Assesment for Insulin Resistance (HOMA index), waist and hip circumference (WHR) and blood pressure (TA) measurement were performed in the study.ResultsPatients treated with risperidone compared to healthy contr...
Metabolic Adverse Events in Patients With Mental Illness Treated With Antipsychotics
The Primary Care Companion to The Journal of Clinical Psychiatry, 2008
Background: Individuals with mental illness are at a higher risk of medical mortality than the general population, primarily due to an increased risk of cardiovascular disease. There are a number of modifiable metabolic risk factors associated with some atypical antipsychotics that warrant careful monitoring and treatment in both psychiatric and primary care practice if the risk of cardiovascular disease is to be effectively reduced. Data Sources: Previous guidelines have focused on awareness of metabolic risk factors in psychiatry, yet few articles have appeared in the primary care-focused journals. We present pragmatic guidelines that focus on monitoring metabolic abnormalities in primary care based on established guidelines, including joint recommendations of the American Diabetes Association, the American Psychiatric Association, the American Association of Clinical Endocrinologists, and the North American Association for the Study of Obesity, and the Mount Sinai conference. Data Synthesis: All patients receiving atypical antipsychotic agents associated with metabolic adverse events should be routinely monitored for weight gain and abnormalities in blood glucose and lipid levels. Effective communication and collaboration between mental health and primary care services and better access to primary care screening and treatment for individuals with mental health problems are needed. Conclusion: There is a clear need for awareness among primary care physicians, particularly as metabolic effects of atypical antipsychotics such as blood pressure and glucose and lipid levels are possibly best monitored in a primary care setting.
Metabolic syndrome with the atypical antipsychotics
Current Opinion in Endocrinology, Diabetes and Obesity, 2010
Purpose of review Metabolic syndrome and cardiovascular diseases are important causes of morbidity and mortality among patients with severe mental illnesses. Atypical or second-generation antipsychotics (SGAs) are associated with obesity and other components of metabolic syndrome, particularly abnormal glucose and lipid metabolism. This review aims to provide a summary of recent evidence on metabolic risks associated with SGAs, current recommendations for metabolic monitoring, and efficacy of treatment options currently available. Recent findings Studies have identified younger, antipsychotic-naive patients with first-episode psychosis as a population vulnerable to adverse metabolic effects from SGAs. These patients gained more weight and developed evident lipid and glucose abnormalities as soon as 8-12 weeks after treatment initiation. Findings are more striking among children and adolescents. The differential effects of various SGAs are well described, with clozapine and olanzapine associated with the highest metabolic risk. In addition to behavioral therapy, emerging data suggest that pharmacological therapy, most notably metformin, is efficacious in the treatment and possibly prevention of SGA-associated metabolic derangements. Summary More data have become available on the burden from metabolic complications associated with SGAs. New and effective treatment options are required in the near future to improve cardiovascular health in this susceptible population.

The presence of the metabolic syndrome is an important risk factor for cardiovascular disease and diabetes. There are limited data on the prevalence of the metabolic syndrome in European patients suffering from schizophrenia. Methods: All consecutive patients with schizophrenia at our university psychiatric hospital and affiliate services were entered in an extensive prospective metabolic study including an oral glucose tolerance test. The prevalence of the metabolic syndrome was assessed based on the National Cholesterol Education Program criteria (NCEP, Adult Treatment Protocol, ATP-III), adapted ATP-III criteria using a fasting glucose threshold of 100 mg/dl (AHA) and on the recently proposed criteria from the International Diabetes Federation (IDF). Results: The analysis of 430 patients showed a prevalence of the metabolic syndrome of 28.4% (ATP-III), 32.3% (ATP-III A) and 36% (IDF), respectively. The prevalence of the metabolic syndrome in our sample of patients with schizophrenia is at least twice as high compared to an age-adjusted community sample in Belgium. Conclusion: The metabolic syndrome is highly prevalent among treated patients with schizophrenia. It represents an important risk for cardiovascular and metabolic disorders. Assessment of the presence and monitoring of the associated risks of the metabolic syndrome should be part of the clinical management of patients treated with antipsychotics. D
