Neuroleptic Metabolic Syndrome: The New NMS

Objectives: The objective of this research was to understand physician, patient, and parent perspectives on barriers to second-generation antipsychotic (SGA) medication adherence in youth with bipolar spectrum disorders, and attitudes toward treatment of SGA-related weight gain. Methods: Patients diagnosed with bipolar disorder before age 18, parents of children diagnosed before 18, and clinicians with experience prescribing SGAs for these patients completed surveys regarding SGA-related side effects, adherence barriers, and acceptability of weight management strategies...

BACKGROUND: Antipsychotic treatment is associated with metabolic disturbance. However, the degree to which metabolic alterations occur in treatment with different antipsychotics is unclear. Predictors of metabolic dysregulation are poorly understood and the association between metabolic change and change in psychopathology is uncertain. We aimed to compare and rank antipsychotics on the basis of their metabolic side-effects, identify physiological and demographic predictors of antipsychotic-induced metabolic dysregulation, and investigate the relationship between change in psychotic symptoms and change in metabolic parameters with antipsychotic treatment...

Second-generation antipsychotics are associated with moderate benefits in terms of improved schizophrenia symptoms, but also with higher rates of side-effects such as excessive weight gain (WG); a consensus on their efficacy has not been reached. To date, no study has evaluated the interplay of treatments and side-effects in a single framework, which is a critical step to clarify the role of side-effects in explaining the efficacy of these antipsychotics. We used recent methods for mediation and interaction to clarify the role of WG in explaining the effects of second-generation drugs on schizophrenia symptoms...

BACKGROUND: Treatment-emergent weight gain is associated with antipsychotic efficacy in schizophrenia patients treated with clozapine and olanzapine. However, few studies have investigated this relationship in first-episode patients treated with other antipsychotics, in particular those with a lower obesogenic potential. Aim To investigate the relationships between weight gain and associated metabolic changes with psychopathology improvement in relation to age, sex, ethnicity, substance use, treatment duration and antipsychotic dose in first-episode schizophrenia spectrum disorder patients...

Importance: Compared with the general population, patients with schizophrenia have a 2- to 3-fold higher mortality rate primarily caused by cardiovascular disease. Previous interventions designed to counteract antipsychotic-induced weight gain and cardiometabolic disturbances reported limited effects. Objectives: To determine the effects of the glucagon-like peptide-1 receptor agonist liraglutide added to clozapine or olanzapine treatment of schizophrenia spectrum disorders...

OBJECTIVE: Diabetes mellitus contributes to excessive cardiovascular deaths and reduced life expectancy in schizophrenia. This population-based cohort study investigated the endogenous risk for diabetes in antipsychotic-naive schizophrenia and evaluated the risks added by starting antipsychotic treatment in people with schizophrenia. METHOD: The study followed all people born in Denmark on or after Jan. 1, 1977, until Jan. 1, 2013 (N=2,736,510). The Danish Psychiatric Central Research Register ascertained schizophrenia diagnoses...

Background: Reverse colocation care models reduce lifestyle risk factors, emergency department visits, and readmissions. Persons with serious mental illness have higher than average rates of cardiovascular disease-related morbidity and mortality, with second-generation antipsychotics (SGAs) conferring added related risks. Little is written about reverse colocated medical care (RCL) in inpatient psychiatric settings. The objective of this study was to identify associations between screening, diagnosis, and treatment of chronic medical comorbidities and mode of medical care for patients discharged from 2 inpatient psychiatric units on SGAs...

OBJECTIVE: It is well established that schizophrenia patients have high cardiovascular morbidity and mortality. However, the underlying risk factors in the earliest stages of both schizophrenia illness and antipsychotics treatment are less clear. This study aimed to characterize the metabolic features of those patients. METHODS: We performed a retrospective cohort study in a naturalistic setting, which included antipsychotic-naïve, first-episode schizophrenia (FES) inpatients with the baseline metabolic measurements and changes following a short term treatment with antipsychotic drugs...

IMPORTANCE: Atypical antipsychotic medications are indicated for the treatment of irritability and agitation symptoms in children with autism spectrum disorder (ASD). Unfortunately, these medications are associated with weight gain and metabolic complications that are especially troubling in children and with long-term use. OBJECTIVE: To evaluate the efficacy of metformin for weight gain associated with atypical antipsychotic medications in children and adolescents with ASD (defined in the protocol as DSM-IV diagnosis of autistic disorder, Asperger disorder, or pervasive developmental disorder not otherwise specified), aged 6 to 17 years...

BACKGROUND: Antipsychotic-induced metabolic adversities are often difficult to manage. Using concomitant medications to counteract these adversities may be a rational option. OBJECTIVE: To systematically determine the effectiveness of medications to counteract antipsychotic-induced metabolic adversities in patients with schizophrenia. DATA SOURCES: Published articles until November 2013 were searched using 5 electronic databases. Clinical trial registries were searched for unpublished trials...

This meta-analysis examined the effectiveness and safety of metformin to prevent or treat weight gain and metabolic abnormalities associated with antipsychotic drugs. We systematically searched in both English- and Chinese-language databases for metformin randomized controlled clinical trials (RCTs) using placebo in patients taking antipsychotics. Twenty-one RCTs (11 published in English and 10 in Chinese) involving 1547 subjects (778 on metformin, 769 on placebo) were included in this meta-analysis. Metformin was significantly superior to placebo (standard mean differences, -0...

Excess deaths from cardiovascular disease are a major contributor to the significant reduction in life expectancy experienced by people with schizophrenia. Important risk factors in this are smoking, alcohol misuse, excessive weight gain and diabetes. Weight gain also reinforces service users' negative views of themselves and is a factor in poor adherence with treatment. Monitoring of relevant physical health risk factors is frequently inadequate, as is provision of interventions to modify these. These guidelines review issues surrounding monitoring of physical health risk factors and make recommendations about an appropriate approach...

Although weight gain is a serious but variable adverse effect of antipsychotics that has genetic underpinnings, a comprehensive meta-analysis of pharmacogenetics of antipsychotic-related weight gain is missing. In this review, random effects meta-analyses were conducted for dominant and recessive models on associations of specific single nucleotide polymorphisms (SNP) with prospectively assessed antipsychotic-related weight or body mass index (BMI) changes (primary outcome), or categorical increases in weight or BMI (≥7%; secondary outcome)...

OBJECTIVE: We examine weight gain and metabolic consequences of risperidone monotherapy in children with autism spectrum disorder (ASD). METHOD: This was a 24-week, multisite, randomized trial of risperidone only versus risperidone plus parent training in 124 children (mean age 6.9 ± 2.35 years; 105 boys and 19 girls) with ASD and serious behavioral problems. We monitored height, weight, waist circumference, and adverse effects during the trial. Fasting blood samples were obtained before treatment and at week 16...

This review will concentrate on the clinical pharmacology, in particular pharmacodynamic data, related to atypical antipsychotics, clozapine, risperidone, paliperidone, olanzapine, que¬tiapine, amisulpride, ziprasidone, aripiprazole, asenapine, iloperidone, lurasidone and cariprazine. A summary of their acute pharmacokinetics properties are also reported. Four new second-generation antipsychotics are available: iloperidone, asenapine, lurasidone and in the next future cariprazine. Similar to ziprasidone and aripiprazole, these new agents are advisable for the lower propensity to give weight gain and metabolic abnormalities in comparison with older second-generation antipsychotics such as olanzapine or clozapine...

Several antipsychotics have well-known adverse metabolic effects. Studies uncovering molecular mechanisms of such drugs in patients are challenging due to high dropout rates, previous use of antipsychotics and restricted availability of biological samples. Rat experiments, where previously unexposed animals are treated with antipsychotics, allow for direct comparison of different drugs, but have been hampered by the short half-life of antipsychotics in rodents. The use of long-acting formulations of antipsychotics could significantly increase the value of rodent models in the molecular characterization of therapeutic and adverse effects of these agents...
