Metabolic syndrome antipsychotic

Long-term treatment of schizophrenia with clozapine (CLZ), an atypical antipsychotic drug, is associated with an increased incidence of metabolic disorders mediated by poorly understood mechanisms. We herein report that CLZ, while slowing down the morphological changes and lipid accumulation occurring during SW872 cell adipogenesis, also causes an early (day 3) inhibition of the expression/nuclear translocation of CAAT/enhancer-binding protein β and peroxisome proliferator-activated receptor γ...

IMPORTANCE: Bipolar disorder affects approximately 8 million adults in the US and approximately 40 million individuals worldwide. OBSERVATIONS: Bipolar disorder is characterized by recurrent episodes of depression and mania or hypomania. Bipolar depressive episodes are similar to major depressive episodes. Manic and hypomanic episodes are characterized by a distinct change in mood and behavior during discrete time periods. The age of onset is usually between 15 and 25 years, and depression is the most frequent initial presentation...

Patients diagnosed with schizophrenia are characterized by early mortality compared to the general population. The main cause of this premature death reflects medical complications linked to metabolic syndrome (MetS). The use of antipsychotics such as clozapine is associated with weight gain and metabolic disturbances in certain predisposed individuals. Non-pharmacological interventions for weight control have become a key element for secondary prevention in the health of patients diagnosed with schizophrenia...

Schizophrenia spectrum disorders (SSD) are complex mental disorders, and while treatment with antipsychotics is important, many patients do not respond or develop serious side effects. Genetic variation has been shown to play a considerable role in determining an individual's response to antipsychotic medication. However, previous pharmacogenetic (PGx) studies have been limited by small sample sizes, lack of consensus regarding relevant genetic variants, and cross-sectional designs. The current study aimed to investigate the association between PGx variants and long-term clinical outcomes in 691 patients of European ancestry with SSD...

Clozapine is listed as one of the most effective antipsychotics and has been approved for treating treatment-resistant schizophrenia (TRS); however, several type A and B adverse reactions, including weight gain, metabolic complications, cardiotoxicity, convulsions, and discontinuation syndromes, exist. The critical mechanisms of clinical efficacy for schizophrenia, TRS, and adverse reactions of clozapine have not been elucidated. Recently, the GABA isomer L-β-aminoisobutyric acid (L-BAIBA), a protective myokine in the peripheral organs, was identified as a candidate novel transmission modulator in the central nervous system (CNS)...

OBJECTIVES: The main aim of the study was to assess the incidence of metabolic syndrome and its individual components in patients subject to a confinement measure, treated with antipsychotics in mono - or polytherapy. Additional objectives included the analysis of associations between the occurrence of metabolic syndrome and patients' age, psychiatric diagnosis, overweight or obesity, and the presence of addictions to psychoactive substances. METHODS: The study involved 61 patients of the Department of Forensic Psychiatry, including 9 women and 52 men, subject to a confinement measure from September 2019 to August 2021...

OBJECTIVES: Neuroleptic malignant syndrome (NMS) is a life-threatening condition that occurs as an adverse reaction to antipsychotic and antiemetic agents or sudden withdrawal of dopaminergic medications. Given the metabolic and functional reserves and the comorbidities in older adults, NMS may show an atypical course. METHODS: The medical records of patients with neurodegenerative diseases leading to dementia between 2013 and 2020 were reviewed for the diagnosis of NMS...

BACKGROUND: Clozapine is considered one of the most effective antipsychotic drugs, but it is most likely to cause metabolic abnormalities. Researchers have studied the causes of metabolic abnormalities caused by clozapine from multiple perspectives, but the reasons remain unclear. PURPOSE: Characterize the gut microbiota of people with schizophrenia taking clozapine, exploring the association between gut microbiota and glucose lipid metabolic markers in schizophrenia patients taking clozapine...

Metabolic disorders (dysglycaemia, dyslipidaemia, metabolic syndrome) may occur or worsen with antidepressants. Even if the metabolic risk appears lower with antidepressants than with certain atypical antipsychotics, it should not be neglected in clinical practice, especially with antidepressants that are associated with weight gain. Metabolic disorders may occur with both selective serotonin reuptake inhibitors and tricyclics, but with some between-molecule differences within each pharmacological family. Besides potential deleterious effects of medications, the psychiatric population is also exposed to bad lifestyle habits (unhealthy diet and sedentary life) and poor medication compliance, which all together could also contribute to enhance the risk of metabolic disorders and cardiovascular complications...

Schizophrenia is a chronic neuropsychiatric illness defined by the appearance of positive, and negative symptoms and/or cognitive impairment. Antipsychotic drugs are predominantly used in the treatment of psychotic disorders, but not all patients with schizophrenia respond to every antipsychotic medication. Clozapine is one of the best atypical antipsychotics and is highly effective in treating treatment-resistant schizophrenia. Evidence suggests that clozapine appears to be effective in lowering the risk of suicide, extrapyramidal side effects, and relapse in patients with schizophrenia...

The aim of this study was to evaluate how schizophrenia spectrum disorders (SSD) and applied long-term (5.1 years) antipsychotic (AP) treatment affect the serum levels of tryptophan (Trp) metabolites. A total of 112 adults (54 first-episode psychosis [FEP] patients and 58 control subjects [CSs]) participated in the study. The investigated changes in the metabolite levels appeared against a background of persistent increase in BMI and waist circumference among the patients. Regarding the kynurenine (KYN) pathway, the strongest changes were seen in AP-naïve FEP patients...

CYP2D6 analysis prior to the prescription of pimozide is required above a certain dose by the Food and Drug Administration in order to detect individuals with the poor metabolizer status. This precautionary measure aims to prevent the occurrence of serious adverse drug reactions. This study presents a case of a patient diagnosed with schizophrenia spectrum disorder. The patient suffered re-admission in the psychiatry ward because of severe secondary symptoms due to the antipsychotic drug pimozide, previously prescribed on a first admission...

Schizophrenia is a chronic debilitating condition associated with impaired social functioning, memory, and executive functioning. To date, we are still unsure about the exact etiology of schizophrenia, but there are many factors, such as genetics, diminished hippocampal volume, and imbalance of neurotransmitters, that lead to the pathogenies of the disease. Antipsychotics are the most effective treatment option for schizophrenia so far, yet they are associated with a wide array of side effects, ranging from extrapyramidal side effects to conditions, such as metabolic syndrome...

BACKGROUND A first psychotic episode requires the exclusion of toxic-metabolic, inflammatory, infective, and neoplastic causes. Wilson disease is a rare, autosomal recessive disorder of copper metabolism and can present with neuropsychiatric symptoms secondary to copper accumulation in the brain. CASE REPORT We describe the case of a 48-year-old man with parkinsonism on a background of longstanding schizophrenia and psychotic depression in the setting of previously undiagnosed Wilson disease. The common history of neuropsychiatric disturbance and neuroleptic use complicated the assessment of parkinsonism...

Objective: Metabolic syndrome is a potential side effect of atypical antipsychotics which are the current standard treatment for schizophrenia. Therefore, we aimed to examine the effect of barberry root (Berberis vulgaris) on the prevention of metabolic syndrome caused by atypical antipsychotic drugs in patients with schizophrenia. Method : Our research was a three-blind randomized clinical trial. The participants included all patients who were diagnosed with schizophrenia through the SCID-5 questionnaire and based on the DSM-5-TR criteria by two psychiatric experts...

BACKGROUND: The most common causes of death in schizophrenia are cardiovascular disorders, which are closely related to metabolic syndrome/obesity. To better understand the development of metabolic alterations early in the course of illness, we quantified daily medication exposure in the first days of the first hospitalization for psychosis and related it to changes in weight and metabolic markers. STUDY DESIGN: We recruited participants with first episode psychosis (FEP, N = 173) during their first psychiatric hospitalization and compared them to controls (N = 204)...

Introduction: Prescription of second-generation antipsychotics (SGAs) in youths is rapidly increasing globally, despite the potential for significant adverse effects and long-term health consequences. A known adverse reaction resulting from SGAs is metabolic syndrome (MS). Youths exposed to antipsychotics are at higher risk than adults for adverse drug reactions, including adverse events such as MS (with weight gain as the most significant adverse outcome) and other long-term endocrinological abnormalities...

INTRODUCTION: Metformin has shown good efficacy in the management of antipsychotic-induced metabolic syndrome (MetS) in patients with schizophrenia or schizoaffective disorders. Its ability to induce antidepressant behavioural effects and improve cognitive functions has also been investigated: yet information has not been systematized. The aim of this study was therefore to investigate the effects of metformin on cognitive and other symptom dimension in schizophrenic patients treated with antipsychotics through a systematic review and meta-analysis...

Paliperidone is an atypical antipsychotic medication commonly used to treat schizophrenia, schizoaffective disorder, and bipolar disorder. It is a metabolite of risperidone and has a similar mechanism of action, primarily blocking dopamine 2 receptors (D2 receptors) in the brain. Paliperidone has various adverse effects, including extrapyramidal symptoms, weight gain, and metabolic disturbances. Catatonia is rare but severe side effects can occur in the context of an underlying psychiatric, neurologic, or general medical condition...

BACKGROUND: First-episode psychosis (FEP) is associated with metabolic alterations. However, it is not known if there is heterogeneity in these alterations beyond what might be expected due to normal individual differences, indicative of subgroups of patients at greater vulnerability to metabolic dysregulation. METHODS: We employed meta-analysis of variance, indexed using the coefficient of variation ratio (CVR), to compare variability of the following metabolic parameters in antipsychotic naïve FEP and controls: fasting glucose, glucose post-oral glucose tolerance test (OGTT), fasting insulin, insulin resistance, haemoglobin A1c (HbA1c ), total-cholesterol, low-density lipoprotein (LDL)-cholesterol, high-density lipoprotein (HDL)-cholesterol, and triglycerides...
