The case of a 4 years old boy, hospitalized for an unexplained coma, is reported. He is the first child of a non-consanguin couple. The psychomotor development of this child was considered as normal up to the age of 18 months; then, a delay in language development, behaviour disorders with an important instability interrupted by episodes of somnolence, were observed. This child was treated for psychotic disorders. At the age of 3 and half, he had two episodes of seizures associated with fever. He was hospitalized for a 24 hours coma (4 years old). An hepatomegaly and a dry, brittle hair were then observed. Hyperammonemia was made obvious by a protein tolerance test. The diagnosis of argininosuccinate lyase (ASAL) deficiency was based on the increased levels of ASA in plasma and urine. The deficiency was proved by a fibroblast culture. With protein restriction, hepatomegaly disappeared, hair became normal, the behaviour disorders and the delay in language development was improved. However, some school difficulties persist. This case shows that an hereditary metabolic syndrome can be revealed by psychotic like symptoms in childhood.

BACKGROUND: Since the introduction of the first atypical antipsychotics in the early 1990s, this class of medication has been increasingly relied upon for the treatment of a variety of patients with psychotic and mood disorders.DATA SOURCES: The following retrospective review was derived from the MEDLINE database using the search terms metabolic syndrome, insulin resistance, obesity, diabetes, severe mental illness, schizophrenia, bipolar disorder, mood disorders, depression, unipolar depression, and prevalence from 1966 to the present. LITERATURE SYNTHESIS: Coincident with the growing usage of these agents, there have been a growing number of literature reports of changes in metabolic homeostasis among patients taking these medications. These changes have led to interest in evaluating whether there is a relationship among these mental illnesses, their psychiatric treatments, and certain physical comorbidities known collectively as the metabolic syndrome. This article reviews the existing literature around the metabolic syndrome in patients with severe mental illnesses. CONCLUSION: Patients with severe mental illnesses, particularly schizophrenia and chronic mood disorders, demonstrate a higher prevalence of metabolic syndrome or its components compared with the general population. Based upon this increased risk in these patients, baseline and periodic medical evaluations should become a standard component in ongoing clinical assessment.

The metabolic effect of atypical antipsychotic drugs may manifest itself in weight gain, disturbances in glucose homeostasis and dyslipidemia. One confounding factor is that psychotic disorders themselves make the patients prone to specific metabolic changes. Nevertheless clinical studies have confirmed that atypical anti-psychotic drugs have a different metabolic effect. In the present prospective case-series, four male antipsychotic drug-naive psychiatric patients without any familial history of metabolic disorder were studied. The patients received risperidone or olanzapine monotherapy for 12 weeks; weight, plasma levels of triglyceride, cholesterol, HDL, and fasting glucose were measured in every 4th week. In two patients, oral glucose tolerance test (OGTT) was also performed at days 0 and 56. The average weight gain during the 12-week period was 12%. The cholesterol and triglyceride plasma concentrations were also elevated. The fasting glucose levels did not change during the observation period. In the OGTT performed in two patients, normal fasting glucose and insulin plasma levels were observed after 8 weeks; however, the plasma insulin concentrations were highly elevated after glucose intake, which may suggest the presence of insulin resistance. Our preliminary results confirmed the previous results on the metabolic effect of atypical anti-psychotic drugs, which may lead to metabolic syndrome. The regular control of the metabolic laboratory parameters, early intervention and the modification of the atypical antipsychotic treatment may help to avoid this adverse effect of the drugs.

The introduction of second-generation antipsychotic drugs for the treatment of schizophrenia has provided significant benefits for clients experiencing this disorder. While they have been found effective in reducing psychotic symptoms, there is evidence that these drugs are also linked with a group of side effects commonly known as the metabolic syndrome. Mental health nurses are well positioned to prevent, detect and/or manage the development of this problematic constellation of symptoms. Guidelines for practice can be useful in prevention and management of the syndrome and enhance nursing care of clients who are taking second-generation antipsychotics.

Patients with severe mental illness have elevated rates of cardiovascular disease (CVD) and diabetes compared with the general population, but little is known about the prevalence of the metabolic syndrome that predisposes patients with severe mental illness to both medical conditions. The purpose of this study was to assess the prevalence of the metabolic syndrome by surveying hospital records of psychiatric inpatients with severe mood and psychotic disorders. The study group was 102 consecutively admitted adult patients with a primary DSM-IV diagnosis of a mood or psychotic disorder. Criteria for comorbid metabolic syndrome required at least three of the five factors defined by the National Cholesterol Education Program. The prevalence of the metabolic syndrome was 38.6% in this cohort, and it was associated with increasing age, body mass index, and Caucasian ethnicity. The metabolic syndrome was common in this cohort of psychiatric inpatients, and the high rate of the metabolic syndrome likely represents an intermediate step in the future development of CVD and diabetes, which may provide a point of early intervention to prevent the occurrence of these two medical illnesses in chronically mentally ill patients.

Depression affects millions of people in the United States. Drugs used to treat depression can lead to weight gain, which could predispose a person to type 2 diabetes. Also, certain medications that may be used to treat depression with psychotic features can lead to metabolic syndrome and new-onset diabetes. Diabetes is another chronic health care condition that affects millions of people in the United States. Diabetes is the leading cause of nontraumatic amputations and a leading cause of blindness. Both conditions can result in a lower quality of life. Clinicians face challenges in treating either condition, but can face greater ones when the conditions occur together. This article reviews the literature concerning depression and diabetes.

Reviews of the association between psychotic disorder, the metabolic syndrome, diabetes, and antipsychotic drugs conclude that there is a need for active, routine physical health screening of patients' prescribed antipsychotic drugs. From published guidelines, we derived the audit standard that all such patients should, as a minimum, have their blood pressure, body mass index (BMI) (or other measure of obesity such as waist circumference), blood glucose (or HbA(1c)), and plasma lipids measured at least once a year. We conducted an audit of the clinical records of 1966 eligible patients under the care of 48 multidisciplinary, assertive outreach clinical teams in 21 mental health services across the United Kingdom. This revealed a recorded measurement within the previous year for blood pressure in 26% of the patients, obesity in 17%, blood glucose (or HbA(1c)) in 28% and plasma lipids in 22%, with all 4 measures documented in 11%. In the total national sample, 6% had a documented diagnosis of diabetes, 6% hypertension, and 6% dyslipidemia. Extrapolating from the prevalence of these disorders in similar populations suggests that for every patient with a known diagnosis of diabetes, another had not been recognized, for every known case of hypertension, 4 had been missed, and for every known case of dyslipidemia, 7 had been missed. The responses of the clinical teams to a questionnaire yielded information on obstacles to screening in routine practice, revealing uncertainty about whose responsibility this was, a lack of confidence about the interpretation of abnormal screening results, and limited access to basic equipment.

The frequency of obesity, insulin resistance, type 2 diabetes mellitus and other components of metabolic syndrome appear to be significantly elevated in some psychiatric patients. This is a notable example of genetic/environment interaction. Considering the genetic contribution, evidence of insulin resistance in persons with schizophrenia was reported in the pre-pharmacological era. High insulin, glucose, and cortisol levels are observed in first episode psychosis. The frequency of type 2 diabetes mellitus is significantly increased in persons with schizophrenia and bipolar disorder and in their first-degree relatives. Finally, a link exists between schizophrenia and enzymes involved in glycolysis and between antipsychotic drug-induced weight gain and serotonin receptor polymorphism. Important environmental factors are poor dietary habits, smoking, lack of physical exercise, and drug treatment, mostly with antipsychotic drugs (APDs) and perhaps with mood stabilizers. The APDs probably induce metabolic dysfunction by producing sudden appetite increase and weight gain in predisposed subjects. However, direct drug effects on glucose and lipid metabolism independent from body weight change have been proposed. Excessive weight gain is mainly observed with clozapine, olanzapine, chlorpromazine, and thioridazine and is less consistently noted with risperidone or quetiapine. Two recently introduced APDs, ziprasidone and aripiprazole, display a neutral effect on weight and metabolism. Subjects at high risk must be identified early during APD treatment so that provide lifestyle counseling and pharmacological assistance can be provided. The immediate research agenda for the APDs is to improve the animal models of drug-induced metabolic dysfunction; to clarify mechanisms other than weight gain and appetite stimulation; and to test pharmacological agents in randomized, double-blind studies to prevent or reverse metabolic syndrome in selected patients.

Clozapine is known to be associated with higher risk of metabolic syndrome, including dyslipidaemia, but the mechanisms of such a relationship are still under debate. The case we reported shows a seemingly dose-dependent effect of clozapine on a patient's lipid profiles with no influence on his blood sugar in a relatively short period of time. A direct effect of clozapine on lipid metabolism, independent of insulin or obesity-related metabolic changes, is suggested. The rapid effect of clozapine on lipid profile allows fine-tuning in dose adjustment while treating refractory schizophrenia complicated with drug-related dyslipidaemia but worrying about psychotic rebound during clozapine discontinuation.

Revisions of DSM and ICD are forthcoming. Should the old categories of psychotic disorder, in particular the construct of schizophrenia, be retained or is a new system of representation of psychosis in order? It is argued that both scientific and societal developments point to a system of classification combining categorical and dimensional representations of psychosis in DSM and ICD. Furthermore, it is proposed to introduce, analogous to the functional descriptive term ;metabolic syndrome', the diagnosis of salience dysregulation syndrome. Within this syndrome, three sub-categories may be identified, based on scientific evidence of relatively valid and specific contrasts: with affective expression; with developmental expression; and not otherwise specified.
