Chang SC, Goh KK, Lu ML. Metabolic disturbances associated with antipsychotic drug treatment in patients with schizophrenia: State-of-the-art and future perspectives. World J Psychiatry 2021; 11:696-710. [PMID: 34733637 PMCID: PMC8546772 DOI: 10.5498/wjp.v11.i10.696] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2021] [Revised: 03/16/2021] [Accepted: 08/31/2021] [Indexed: 02/06/2023] Open
Abstract
Metabolic disturbances and obesity are major cardiovascular risk factors in patients with schizophrenia, resulting in a higher mortality rate and shorter life expectancy compared with those in the general population. Although schizophrenia and metabolic disturbances may share certain genetic or pathobiological risks, antipsychotics, particularly those of second generation, may further increase the risk of weight gain and metabolic disturbances in patients with schizophrenia. This review included articles on weight gain and metabolic disturbances related to antipsychotics and their mechanisms, monitoring guidelines, and interventions. Nearly all antipsychotics are associated with weight gain, but the degree of the weight gain varies considerably. Although certain neurotransmitter receptor-binding affinities and hormones are correlated with weight gain and specific metabolic abnormalities, the precise mechanisms underlying antipsychotic-induced weight gain and metabolic disturbances remain unclear. Emerging evidence indicates the role of genetic polymorphisms associated with antipsychotic-induced weight gain and antipsychotic-induced metabolic disturbances. Although many guidelines for screening and monitoring antipsychotic-induced metabolic disturbances have been developed, they are not routinely implemented in clinical care. Numerous studies have also investigated strategies for managing antipsychotic-induced metabolic disturbances. Thus, patients and their caregivers must be educated and motivated to pursue a healthier life through smoking cessation and dietary and physical activity programs. If lifestyle intervention fails, switching to another antipsychotic drug with a lower metabolic risk or adding adjunctive medication to mitigate weight gain should be considered. Antipsychotic medications are essential for schizophrenia treatment, hence clinicians should monitor and manage the resulting weight gain and metabolic disturbances.

Impact of Lurasidone and Other Antipsychotics on Body Weight: Real-World, Retrospective, Comparative Study of 15,323 Adults with Schizophrenia. Int J Gen Med 2021; 14:4081-4094. [PMID: 34366678 PMCID: PMC8336993 DOI: 10.2147/ijgm.s320611] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Accepted: 07/09/2021] [Indexed: 01/03/2023] Open
Abstract
Purpose The primary objectives were to describe weight changes following initiation of lurasidone versus other antipsychotics and estimate the risk of clinically relevant (≥7%) weight changes. Patients and Methods This retrospective, longitudinal comparative cohort study was based on electronic medical records (EMRs) of United States (US) adult patients with schizophrenia who were prescribed lurasidone or other antipsychotics as monotherapy between 1 April 2013 and 30 June 2019. Results Overall, the study included 15,323 patients with a diagnosis of schizophrenia; 6.1% of patients received lurasidone, 60.4% received antipsychotics associated with a medium-high risk of weight gain (clozapine, olanzapine, quetiapine, risperidone, paliperidone) and 33.5% received antipsychotics with a low risk of weight gain (aripiprazole, first-generation antipsychotics, ziprasidone). Lurasidone was associated with the smallest proportion of patients experiencing clinically relevant weight gain and the greatest proportion of patients with clinically relevant weight loss. The risk of clinically relevant weight gain was numerically higher with all antipsychotics versus lurasidone and was statistically significant for olanzapine (hazard ratio [HR]=1.541; 95% confidence interval [CI]=1.121; 2.119; p=0.0078) versus lurasidone. The likelihood of ≥7% weight loss was significantly greater with lurasidone versus all antipsychotics (p<0.05), except ziprasidone. Conclusion This real-world study suggests that lurasidone has a lower risk of clinically relevant weight gain and a higher likelihood of clinically relevant weight loss than other commonly used antipsychotics.

Gender disparities in clozapine prescription in a cohort of treatment-resistant schizophrenia in the South London and Maudsley case register. Schizophr Res 2021; 232:68-76. [PMID: 34022618 DOI: 10.1016/j.schres.2021.05.006] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Revised: 04/29/2021] [Accepted: 05/01/2021] [Indexed: 11/30/2022]
Abstract
BACKGROUND Gender disparities in treatment are apparent across many areas of healthcare. There has been little research into whether clozapine prescription, the first-line treatment for treatment-resistant schizophrenia (TRS), is affected by patient gender. METHODS This retrospective cohort study identified 2244 patients with TRS within the South London and Maudsley NHS Trust, by using a bespoke method validated against a gold-standard, manually coded, dataset of TRS cases. The outcome and exposures were identified from the free-text using natural language processing applications (including machine learning and rules-based approaches) and from information entered in structured fields. Multivariable logistic regression was carried out to calculate the odds ratios for clozapine prescription according to patients' gender, and adjusting for numerous potential confounders including sociodemographic, clinical (e.g., psychiatric comorbidities and substance use), neutropenia, functional factors (e.g., problems with occupation), and clinical monitoring. RESULTS Clozapine was prescribed to 77% of the women and 85% of the men with TRS. Women had reduced odds of being prescribed clozapine as compared to men after adjusting for all factors included in the present study (adjusted OR: 0.66; 95% CI 0.44-0.97; p = 0.037). CONCLUSION Women with TRS are less likely to be prescribed clozapine than men with TRS, even when considering the effects of multiple clinical and functional factors. This finding suggests there could be gender bias in clozapine prescription, which carries ramifications for the relatively poorer care of women with TRS regarding many outcomes such as increased hospitalisation, mortality, and poorer quality of life.

Abstract
BACKGROUND Few studies have investigated the weight of patients with schizophrenia in China. OBJECTIVE The aim of this study was to analyse the prevalence, clinical characteristics and influencing factors of obesity and underweight in patients with chronic schizophrenia in China. METHODS A total of 325 patients with schizophrenia and 172 sex- and age-matched healthy controls from the community were recruited. Socio-demographic data and laboratory measurements were collected for all subjects. Using the Positive and Negative Syndrome Scale (PANSS), we evaluated the psychiatric symptoms of patients with schizophrenia. According to the body mass index (BMI) criteria in China, BMI ≥ 28 kg/m2 indicates obesity, and BMI < 18.5 kg/m2 indicates underweight. RESULTS Of the patients with schizophrenia, 16.3% were obese, and 6.8% were underweight; 11.0% of the healthy controls were obese, and 3.5% were underweight. There was no difference between the two groups in the prevalence of obesity and underweight. After controlling for relevant variables, the obesity rate remained non significant, but the underweight rate appeared to be different. The multinomial regression analysis revealed that among the patients with schizophrenia, female sex, triglyceride level and LDL level were independent risk factors for obesity and that HDL level was an independent protective factor against obesity. In contrast, male sex and HDL level were independent risk factors for underweight. CONCLUSION We found that the patients with schizophrenia had an increased rate of underweight and some factors related to weight. LEVEL OF EVIDENCE Level V, descriptive study.

Abstract
AIM The present study aimed to investigate the effect of Zingiber officinale (ZO) extract on weight gain, food intake, locomotor activity, and lipid and glucose metabolism in olanzapine-treated rats. METHODS The hydroalcoholic extract of ZO was prepared by macerating the coarse dry powder in 70% v/v ethanol for 7 days, filtered, and concentrated under reduced pressure. Animals were divided into six groups containing six animals in each. Three doses of extract (100, 200, and 400 mg/kg, p.o.) were co-administered with olanzapine 2 mg/kg i.p for 21 days. Bodyweight and food intake were recorded at the interval of three days and locomotor activity once a week. At the end of the study oral glucose tolerance test was performed followed by the estimation of lipid profile. RESULTS Co-administration of hydroalcoholic extract of ZO with olanzapine ameliorated olanzapine-induced weight gain and hyperphagia. Similarly, ZO extract also improved pancreatic β-cell function and glucose and lipid metabolism. CONCLUSIONS ZO extract ameliorated olanzapine-induced weight gain and hyperphagia by improving pancreatic β-cell functions and lipid metabolism.

Abstract
BACKGROUND Patients treated with antipsychotics experience significant weight gain and accompanying metabolic disorders. We investigated the efficacy of liraglutide 3.0 mg in reducing the weight of antipsychotic-treated obese patients. METHOD We retrospectively reviewed 16 obese patients with schizophrenia or bipolar disorder who were treated with 3.0 mg of liraglutide each. During the 16 weeks of treatment, changes in body weight and Clinical Global Impression-Severity scale (CGI-S) were analyzed. The participants were divided into responders (lost at least 5% of body weight) and non-responders for analysis. RESULTS Treatment with liraglutide 3.0 mg significantly decreased body weight (estimated marginal mean, 93.2 kg at baseline and 88.9 kg at 16 weeks; p < 0.001) as well as waist circumference, BMI and plasma glucose levels. Six of 16 patients (37.5%) complained of a modest degree of nausea. Six of the 12 subjects (50%) completing 16 weeks of treatment were responders. There were no significant differences in baseline characteristics between responders and non-responders. There was no worsening of CGI-S scores. CONCLUSION Liraglutide 3.0 mg significantly decreased body weight in obese patients treated with antipsychotics without altering the status of psychiatric diseases. A randomized controlled study is required to corroborate the results of this study.

Abstract
BACKGROUND Visceral adipose tissue (VAT) are deleterious fat deposits in the human body and can be effectively reduced by exercise intervention. Despite well-established exercise prescriptions are available, the effective dosage of exercise for reducing VAT requires verification. OBJECTIVES The aims of this systematic review and meta-analysis were to determine the most effective exercise dosage (modality, intensity, duration, and amount) for decreasing VAT. METHODS Nine databases (EMBASE, Medline, Cochrane Central Register of Controlled Trial, PubMed, CINAHL, Scopus, Web of Science, Airiti Library, and PerioPath) were systematically searched for randomized controlled trials that objectively assessed VAT. The arms of included studies covered with different exercise modalities and dosage. Relevant databases were searched through February 2020. RESULTS Of the 34 studies (n = 1962) included in systematic review, 32 (n = 1900) were pooled for pairwise or network meta-analysis. The results indicated that high-intensity interval training (SMD -0.39, 95% CI -0.60 to -0.18) and aerobic exercise (SMD -0.26, 95% CI -0.38 to -0.13) of at least moderate intensity were beneficial for reducing VAT. By contrast, resistance exercise, aerobic exercise combined with resistance exercise, and sprint interval training had no significant effects. No difference in VAT reduction was observed between exercising more or less than 150 min per week. Meta-regression revealed that the effect of VAT reduction was not significantly influenced by an increase in the duration of or amount of exercise in an exercise program. The effective dosage of exercise for reducing VAT was three times per week for 12 to 16 weeks, while duration per session for aerobic exercise was 30-60 min, and either less than 30 min or 30-60 min of high-intensity interval training accomplished sufficient energy expenditure to impact VAT. CONCLUSIONS These results can inform exercise prescriptions given to the general population for improving health by reducing VAT.

Abstract
INTRODUCTION Nutritional psychiatry is an emerging field of study that investigates the role of diet and nutrition in mental health. Studies conducted in the general population have linked depressive symptoms with poor dietary patterns. The aim of this study was to characterise the dietary intake and analyse the dietary pattern using the Dietary Approach to Stop Hypertension (DASH) in a sample of psychiatric patients in a multiethnic Asian nation. METHODS Participants were recruited from an outpatient clinic and an inpatient unit at the Institute of Mental Health in Singapore. Self-reported dietary habits of a sample of psychiatric patients (N=380) were analysed using DASH. To examine the variables associated with DASH scores, a linear regression was conducted with the full sample and sociodemographic variables. RESULTS Persons with depressive disorders had a mean DASH score of 21.3 (±4.2), while persons with psychotic disorders had a mean DASH score of 21.2 (±4.9). Respondents who were older (B=1.94, 95% confidence interval [CI] 0.91-2.96, P<0.001), female (B=1.09, 95% CI 0.07-2.11, P=0.04) and economically inactive (B=1.98, 95% CI 0.006-3.96, P=0.049) were more likely to report a higher diet quality compared with their respective counterparts, while smokers (B= -1.39, 95% CI -2.45 to -0.34, P=0.009) tended to report a lower diet quality compared with their non-smoking counterparts. CONCLUSION Dietary patterns of persons with mental disorders were characterised. A host of sociodemographic factors, and not diagnosis of mental disorders, influenced the dietary quality of people with depressive and psychotic disorders. Clinicians treating psychiatric patients need to be aware of the nuanced reasons behind poor dietary choices and provide targeted psychoeducation to specific subgroups within the patient population.

Abstract
Atypical antipsychotic drugs are commonly associated with undesirable side effects including body weight gain (BWG) and metabolic deficits. Many pharmacological interventions have been tested in an attempt to minimize or prevent these side effects. Preliminary evidence suggests that antidiabetic drugs may be effective in attenuating antipsychotic-induced BWG. In the current study, we examined the effect of an antidiabetic drug empagliflozin (EMPA) on BWG induced by anatypical antipsychotic drug olanzapine (Ola) in female and male Wistar rats. Rats were divided into six groups based on the dose they received: group 1 (female control), group 2 (female EMPA, 20 mg/kg; IG), group 3 (female Ola, 4 mg/kg; IP), group 4 (female Ola, 4 mg/kg; IP + EMPA, 20 mg/kg; IG), group 5 (male control), and group 6 (male Ola, 4 mg/kg; IP). Ola induced sustained increase in BWG. The subsequent treatment of Group 3 and 4 with EMPA attenuated the Ola-induced BWG in female Wistar rats. In terms of the gender difference between female and male Wistar rats, the male control group 5 gained more weight throughout the study as compared to the female control group 1. Similarly, the male Ola group 6 gained more weight throughout the study as compared to the female Ola group 3. However, Ola did not cause any weight difference between male rats treated with Ola in comparison with male control group, thus showing a significant gender difference regarding body weight between male and female Wistar rats regardless of Ola administration. In addition, the present findings showed that EMPA effectively attenuates the Ola induced BWG in female Wistar rats. These novel findings should help to better understand the underlying molecular and behavioral mechanisms contributing to the observed increase in body weight after treatment with Ola and other atypical antipsychotic drugs across male and female rats.

Abstract
BACKGROUND Rates of overweight and obesity are higher in patients suffering from psychiatric disorders than in the general population. Body composition and enzyme functions are affected by overweight, and consequently, the pharmacokinetics of drugs may vary in overweight patients. Thus, overweight and obesity are important factors in psychiatric disorders and their treatment. This analysis aimed to investigate the impact of body mass index (BMI) on serum concentrations of the antidepressant drugs amitriptyline, doxepin, escitalopram, mirtazapine, and venlafaxine, and the antipsychotic drugs clozapine, quetiapine, and risperidone, taking into account the following confounding parameters: age, sex, and smoking habit. METHODS Inpatients and outpatients (N = 1657) who took at least one of the target drugs were included in this retrospective analysis. Serum concentrations of the target drugs and their metabolites were determined at the Department of Psychiatry, Psychosomatics, and Psychotherapy of the University Hospital of Würzburg during routine therapeutic drug monitoring (January 2009-December 2010), which was performed in the morning (trough level) at steady state. RESULTS Dose-corrected serum concentrations (CD) of the active moiety of doxepin and venlafaxine and of O-desmethylvenlafaxine were negatively associated with BMI (partial Pearson correlation, R = -0.267, P = 0.002; R = -0.206, P ≤ 0.001; R = -0.258, P ≤ 0.001), and the CDs were different in normal weight, overweight, and obese patients (analysis of covariance, P = 0.004, P < 0.001, P ≤ 0.001). No association was found between BMI and serum concentrations of amitriptyline, escitalopram, mirtazapine, clozapine, quetiapine, and risperidone. CONCLUSIONS In obese patients, higher doses of doxepin and venlafaxine are necessary to achieve similar serum concentrations as in normal weight patients and to avoid treatment-resistant depression.

Abstract
BACKGROUND The use of Atypical antipsychotics (AAPs) is related to metabolic disturbances, which put psychiatric patients at risk for cardiovascular morbidity and mortality. Evidence is emerging of genetic risk factors. The HTR2C gene is an essential candidate in pharmacogenetic studies of antipsychotic-induced metabolic effects. Nevertheless, there were inconsistent results among studies. OBJECTIVE To investigate the relationship between -759C/T, functional polymorphism of the HTR2C gene and metabolic adverse effects in Thai psychiatric patients treated with risperidone monotherapy. METHOD In this cross-sectional study, 108 psychiatric patients treated with risperidone monotherapy for ≥3 months were recruited. Anthropometric measurements and laboratory tests were obtained upon enrollment and history of treatment was reviewed from medical records. Weight gain was defined as an increase ≥7% of baseline weight. Metabolic syndrome was evaluated according to the 2005 International Diabetes Federation (IDF) Asia criteria. The -759C/T, polymorphism was genotyped. The associations between -759C/T polymorphism and metabolic side effects were analyzed. Multiple logistic regression was used for determining potential confounders. RESULTS Neither weight gain nor metabolic syndrome was significantly associated with -759C/T allelic and genotype variants of HTR2C. However, T allele of -759C/T polymorphism significantly associated with the hypertension. This association was not affected by possible confounding factors such as gender, risperidone dose, duration of treatment and family history of hypertension. CONCLUSION Our findings suggest that psychiatric patients with T allele of -759C/T polymorphism may be at higher risk for hypertension. Further study with prospective design with larger patient groups are needed.

Abstract
Antipsychotic medications are critical to child and adolescent psychiatry, from the stabilization of psychotic disorders like schizophrenia, bipolar disorder, and psychotic depression to behavioral treatment of autism spectrum disorder, tic disorders, and pediatric aggression. While effective, these medications carry serious risk of adverse events-most commonly, weight gain and cardiometabolic abnormalities. Negative metabolic consequences affect up to 60% of patients and present a major obstacle to long-term treatment. Since antipsychotics are often chronically prescribed beginning in childhood, cardiometabolic risk accumulates. An increased susceptibility to antipsychotic-induced weight gain (AIWG) has been repeatedly documented in children, particularly rapid weight gain. Associated cardiometabolic abnormalities include central obesity, insulin resistance, dyslipidemia, and systemic inflammation. Lifestyle interventions and medications such as metformin have been proposed to reduce risk but remain limited in efficacy. Furthermore, antipsychotic medications touted to be weight-neutral in adults can cause substantial weight gain in children. A better understanding of the biological underpinnings of AIWG could inform targeted and potentially more fruitful treatments; however, little is known about the underlying mechanism. As yet, modest genetic studies have nominated a few risk genes that explain only a small percentage of the risk. Recent investigations have begun to explore novel potential mechanisms of AIWG, including a role for gut microbiota and microbial metabolites. This article reviews the problem of AIWG and AP metabolic side effects in pediatric populations, proposed mechanisms underlying this serious side effect, and strategies to mitigate adverse impact. We suggest future directions for research efforts that may advance the field and lead to improved clinical interventions.

Abstract
BACKGROUND Liraglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist that prevents metabolic side effects of the antipsychotic drugs (APDs) olanzapine and clozapine through unknown mechanisms. AIM This study aimed to investigate the effect of chronic APD and liraglutide co-treatment on key neural and peripheral metabolic signals, and acute liraglutide co-treatment on clozapine-induced hyperglycaemia. METHODS In study 1, rats were administered olanzapine (2 mg/kg), clozapine (12 mg/kg), liraglutide (0.2 mg/kg), olanzapine + liraglutide co-treatment, clozapine + liraglutide co-treatment or vehicle for six weeks. Feeding efficiency was examined weekly. Examination of brain tissue (dorsal vagal complex (DVC) and mediobasal hypothalamus (MBH)), plasma metabolic hormones and peripheral (liver and kidney) cellular metabolism and oxidative stress was conducted. In study 2, rats were administered a single dose of clozapine (12 mg/kg), liraglutide (0.4 mg/kg), clozapine + liraglutide co-treatment or vehicle. Glucose tolerance and plasma hormone levels were assessed. RESULTS Liraglutide co-treatment prevented the time-dependent increase in feeding efficiency caused by olanzapine, which plateaued by six weeks. There was no effect of chronic treatment on melanocortinergic, GABAergic, glutamatergic or endocannabionoid markers in the MBH or DVC. Peripheral hormones and cellular metabolic markers were unaltered by chronic APD treatment. Acute liraglutide co-treatment was unable to prevent clozapine-induced hyperglycaemia, but it did alter catecholamine levels. CONCLUSION The unexpected lack of change to central and peripheral markers following chronic treatment, despite the presence of weight gain, may reflect adaptive mechanisms. Further studies examining alterations across different time points are required to continue to elucidate the mechanisms underlying the benefits of liraglutide on APD-induced metabolic side effects.

Abstract
Objective Weight gain is an important risk factor for morbidity and mortality among patients with schizophrenia. We speculated that positive symptoms, related to dopaminergic hyperactivity and altered mesolimbic function, are associated with weight gain. Methods Twenty-two antipsychotic-naïve, first-episode patients with schizophrenia were enrolled. The Positive and Negative Syndrome Scale was completed at enrollment and follow-up. Body mass index (BMI) was also measured. Results The increase in BMI, after 6.04 ± 2.16 years of follow-up, was associated with positive symptoms, but not negative symptoms, before treatment with antipsychotics in antipsychotic-naïve patients with schizophrenia. Conclusion This finding implied that dopaminergic hyperactivity could be an important factor to predict the treatment outcome. Body weight control is important for the health management of patients with schizophrenia with more severe positive symptoms.

Abstract
Dopamine (DA) and norepinephrine (NE) are catecholamines primarily studied in the central nervous system that also act in the pancreas as peripheral regulators of metabolism. Pancreatic catecholamine signaling has also been increasingly implicated as a mechanism responsible for the metabolic disturbances produced by antipsychotic drugs (APDs). Critically, however, the mechanisms by which catecholamines modulate pancreatic hormone release are not completely understood. We show that human and mouse pancreatic α- and β-cells express the catecholamine biosynthetic and signaling machinery, and that α-cells synthesize DA de novo. This locally-produced pancreatic DA signals via both α- and β-cell adrenergic and dopaminergic receptors with different affinities to regulate glucagon and insulin release. Significantly, we show DA functions as a biased agonist at α2A-adrenergic receptors, preferentially signaling via the canonical G protein-mediated pathway. Our findings highlight the interplay between DA and NE signaling as a novel form of regulation to modulate pancreatic hormone release. Lastly, pharmacological blockade of DA D2-like receptors in human islets with APDs significantly raises insulin and glucagon release. This offers a new mechanism where APDs act directly on islet α- and β-cell targets to produce metabolic disturbances.

Abstract
AIM The primary aim of this study was to standardize the correlated effective dosage of the antidiabetic drug empagliflozin (EMPA) and the antipsychotic drug olanzapine (Ola). BACKGROUND Atypical antipsychotics are associated with BWG and metabolic disturbances for which many approaches have been used to minimize these issues, including antidiabetic drugs. The antidiabetic drugs have been quite effective in reversing BWG induced by the administration of antipsychotic drugs in patients who have psychosis, schizophrenia and bipolar disorder. OBJECTIVE The objective of this study was to standardize the correlated effective dosage of EMPA and Ola. METHODS The study was carried out for 28 days to represent the chronic effect of Ola on female Wistar rats. Rats were divided into three groups based on the dose they received: control (vehicle), Ola-4 and Ola-8 (4 and 8 mg/kg/OD, respectively), and EMPA-10 and EMPA-20 (10 and 20 mg/kg/OD, respectively). RESULTS Both doses of Ola produced a significant increase in the percentage of BWG, however, Ola-4 produced a higher BWG. Also, both the doses of EMPA were able to reverse the effect of Ola-induced BWG; however, EMPA-20 produced a higher reversal in BWG and normalized the rat's body weight. CONCLUSION We conclude that Ola-4 and EMPA-20 were the most effective dosage for experimental purposes in female Wistar rats. The findings of this study standardized the effective correlated dosage of olanzapine and empagliflozin in female Wistar rats that will help understand the underlying molecular and behavioral mechanisms.

Abstract
Introduction Aripiprazole and olanzapine are atypical antipsychotics. Both drugs can induce metabolic changes; however, the metabolic side effects produced by aripiprazole are more benign. The aim of the study was to evaluate if aripiprazole and olanzapine alter prolactin levels, lipid and glucose metabolism and hepatic, haematological, thyroid and renal function. Methods Twenty-four healthy volunteers received a daily oral dose of 10 mg aripiprazole and 5 mg olanzapine tablets for 5 days in a crossover randomised clinical trial and were genotyped for 51 polymorphisms in 18 genes by qPCR. Drug plasma concentrations were measured by LC–MS. The biochemical and haematological analyses were performed by enzymatic methods. Results Olanzapine induced hyperprolactinaemia but aripiprazole did not. Dopamine D3 receptor (DRD3) Ser/Gly and ATP binding cassette subfamily B member 1 (ABCB1) rs10280101, rs12720067 and rs11983225 polymorphisms and cytochrome P450 3A (CYP3A) phenotype had an impact on plasma prolactin levels. C-peptide concentrations were higher after aripiprazole administration and were influenced by catechol-O-methyltransferase (COMT) rs4680 and rs13306278 polymorphisms. Olanzapine and the UDP glucuronosyltransferase family 1 member A1 (UGT1A1) rs887829 polymorphism were associated with elevated glucose levels. CYP3A poor metabolizers had increased insulin levels. Volunteers’ weight decreased significantly during aripiprazole treatment and a tendency for weight gain was observed during olanzapine treatment. Triglyceride concentrations decreased as a result of olanzapine and aripiprazole treatment, and varied on the basis of CYP3A phenotypes and the apolipoprotein C-III (APOC3) rs4520 genotype. Cholesterol levels were also decreased and depended on 5-hydroxytryptamine receptor 2A (HTR2A) rs6314 polymorphism. All hepatic enzymes, platelet and albumin levels, and prothrombin time were altered during both treatments. Additionally, olanzapine reduced the leucocyte count, aripiprazole increased free T4 and both decreased uric acid concentrations. Conclusions Short-term treatment with aripiprazole and olanzapine had a significant influence on the metabolic parameters. However, it seems that aripiprazole provokes less severe metabolic changes.

Abstract
Objectives This study aimed to determine the prevalence of symptoms and risk of obstructive sleep apnoea (OSA) and to identify the risk factors associated with OSA among old Saudis. Methods In this population-based survey, we administered the Saudi National Survey for Elderly Health to old Saudis between 2006 and 2007. Symptoms of OSA and its associated risk factors were determined using the Berlin questionnaire. A multivariable logistic regression analysis was used to determine key factors associated with the risk of OSA. Results Out of 2946 participants, 1544 (52.4%) were at high risk of OSA, with women having a higher risk than men (60.8% vs. 44.2%, respectively; p-value <0.001). Obesity was higher among women than men (40.5% vs. 24.8%, respectively; p-value <0.001). Almost 56% of the participants reported snoring as a risk factor, but there was no statistical difference between women and men (57.3% vs. 53.5%, respectively; p-value = 0.317). The factors identified as independent predictors of a high risk of OSA were the female gender (OR 1.732, 95% CI [1.375–2.182]), living in rural areas (OR 1.384, 95% CI [1.094–1.750]), severe cognitive impairment (OR 2.709, 95% CI [1.350–5.436]), depression (OR: 1.432 95%CI [1.147–1.789]), and antidepressants usage (OR 2.959, 95% CI [1.402–6.244]). Conclusion This study reported a 52.4% prevalence of a high risk of OSA. Women were more likely to be at high risk of OSA than men. In addition to the female gender, depression, antidepressant usage, severe cognitive impairment, and living in rural areas were main predictors of OSA.

Abstract
Introduction: Williams syndrome (WS) is a neurogenetic disorder characterized by a hyper-social personality, intellectual disability, and multiple medical co-morbidities. Psychiatric co-morbidities are also common. Since medical co-morbidities are common in this population, the risk-benefit of the use of psychiatric medications must be carefully considered and monitoring for safety and tolerability is needed.Areas covered: We review the cognitive profile and common medical co-morbidities in WS. We then discuss the common presentations of psychiatric disorders and review the available evidence on the use of psychiatric medications in WS. No prospective psychiatric medication trials have been conducted. We highlight the side effect profile of common psychiatric medications as they pertain to WS.Expert opinion: Psychiatric disorders can have a major effect on the quality of life of individuals with WS. The lack of long-term safety data and high likelihood of medical co-morbidities in WS make the judicious use of psychiatric medications more challenging; however, they can play an important role in decreasing distress and improving functioning. We provide recommendations for first- and second-line classes of medications based on our clinical experience and consideration of adverse effect profiles, as well as safety monitoring parameters at baseline and periodically.

Study protocol of a randomized, double-blind, placebo-controlled, multi-center trial to treat antipsychotic-induced weight gain: the Metformin-Lifestyle in antipsychotic users (MELIA) trial. BMC Psychiatry 2021; 21:4. [PMID: 33402159 PMCID: PMC7783702 DOI: 10.1186/s12888-020-02992-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2020] [Accepted: 11/26/2020] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Antipsychotic-induced Weight Gain (AiWG) is a debilitating and common adverse effect of antipsychotics. AiWG negatively impacts life expectancy, quality of life, treatment adherence, likelihood of developing type-2 diabetes and readmission. Treatment of AiWG is currently challenging, and there is no consensus on the optimal management strategy. In this study, we aim to evaluate the use of metformin for the treatment of AiWG by comparing metformin with placebo in those receiving treatment as usual, which includes a lifestyle intervention. METHODS In this randomized, double-blind, multicenter, placebo-controlled, pragmatic trial with a follow-up of 52 weeks, we aim to include 256 overweight participants (Body Mass Index (BMI) > 25 kg/m2) of at least 16 years of age. Patients are eligible if they have been diagnosed with schizophrenia spectrum disorder and if they have been using an antipsychotic for at least three months. Participants will be randomized with a 1:1 allocation to placebo or metformin, and will be treated for a total of 26 weeks. Metformin will be started at 500 mg b.i.d. and escalated to 1000 mg b.i.d. 2 weeks thereafter (up to a maximum of 2000 mg daily). In addition, all participants will undergo a lifestyle intervention as part of the usual treatment consisting of a combination of an exercise program and dietary consultations. The primary outcome measure is difference in body weight as a continuous trait between the two arms from treatment inception until 26 weeks of treatment, compared to baseline. Secondary outcome measures include: 1) Any element of metabolic syndrome (MetS); 2) Response, defined as ≥5% body weight loss at 26 weeks relative to treatment inception; 3) Quality of life; 4) General mental and physical health; and 5) Cost-effectiveness. Finally, we aim to assess whether genetic liability to BMI and MetS may help estimate the amount of weight reduction following initiation of metformin treatment. DISCUSSION The pragmatic design of the current trial allows for a comparison of the efficacy and safety of metformin in combination with a lifestyle intervention in the treatment of AiWG, facilitating the development of guidelines on the interventions for this major health problem. TRIAL REGISTRATION This trial was registered in the Netherlands Trial Register (NTR) at https://www.trialregister.nl/trial/8440 as NTR NL8840 on March 8, 2020.

Abstract
BACKGROUND The length of stay (LOS) of patients with schizophrenia has been a wide concern of researchers. Reasonable management of the LOS to achieve a balance between quality of treatment and efficient medical source allocation has become a significant issue in clinical work in psychiatry. Figuring out the factors related to the LOS of schizophrenia patients can help optimize its management by the hospital. METHOD The essential information of patients was obtained from the electronic medical record system. The variables were divided into the following kinds: demographic, clinical, and biochemical. Univariate analysis and multivariate analysis were conducted to find the potential factors related to the LOS of schizophrenia patients. Receiver operating characteristic analyses were conducted to evaluate the accuracy of judging the LOS of the regression model. RESULT A total of 1,160 patients with schizophrenia were enrolled in our research. Our results demonstrated that the status of unmarried (single, separated, divorced, or widowed) and the abnormality of thyroid-stimulating hormone (TSH) were risk factors for the longer LOS of schizophrenia patients. The area under the curve was 0.576, which meant that the regression model had a certain predictive value. CONCLUSION To our knowledge, this research is the first study to analyze the effect of various factors, including the biochemical index, on the LOS of a single type of mental disorder. Marital status and TSH were proven to be related to the LOS of schizophrenia patients. The results of this study provided reference factors of LOS for clinical psychiatry, which will be helpful to the management of hospitalization and in optimizing the allocation of medical sources.

Effect of Miricorilant, a Selective Glucocorticoid Receptor Modulator, on Olanzapine-Associated Weight Gain in Healthy Subjects: A Proof-of-Concept Study. J Clin Psychopharmacol 2021; 41:632-637. [PMID: 34369902 PMCID: PMC8575171 DOI: 10.1097/jcp.0000000000001470] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/25/2022]
Abstract
PURPOSE Antipsychotic medications, including olanzapine, are associated with substantial weight gain and metabolic disturbances. We sought to determine whether coadministration of miricorilant, a selective glucocorticoid receptor modulator, with olanzapine can ameliorate these effects. METHODS Sixty-six healthy men were enrolled in a 2-week, randomized, double-blind, placebo-controlled trial. The primary objective was to evaluate changes in body weight after 14 days coadministration of olanzapine (10 mg) + miricorilant (600 mg) compared with olanzapine (10 mg) + placebo. Secondary objectives included evaluating (a) the safety and tolerability of the combination; (b) the effects of the combination on glucose, insulin, insulin resistance, and triglycerides; and (c) the impact of the combination on hepatic enzymes. RESULTS Subjects administered olanzapine + miricorilant gained less weight than subjects administered olanzapine + placebo (mean weight gain on day 15, 3.91 kg vs 4.98 kg; difference between groups, -1.07 kg; 95% confidence interval, -1.94 to -0.19; P = 0.017]). Compared with the placebo group, coadministration of miricorilant with olanzapine was associated with smaller increases in insulin (difference, -3.74 mIU/L; P = 0.007), homeostatic model assessment of insulin resistance (difference, -0.47; P = 0.007), triglycerides (difference, -0.29 mmol/L; P = 0.057), aspartate aminotransferase (difference, -32.24 IU/L; P = 0.009), and alanine aminotransferase (difference, -49.99 IU/L; P = 0.030). CONCLUSIONS Miricorilant may provide a promising option for ameliorating the detrimental effects of olanzapine, and investigation of this medication in patients affected by antipsychotic-induced weight gain is warranted. Two phase 2 studies of miricorilant in patients with recent and long-standing antipsychotic-induced weight gain are currently in progress.

Abstract
Antipsychotic long-acting formulations (LAI-AP) have emerged as a new therapeutic choice to treat patients presenting a severe mental disorder. Despite that, to date, there is a lack of safety data and studies regarding the use of LAI-AP formulations in pregnant women. Here we present the first six-case series of pregnant women with schizophrenia treated with aripiprazole-LAI reported in the literature. All patients remained psychopathologically stable through pregnancy and the postpartum period, and all of them were in treatment with aripiprazole-LAI. To date, all infants remain healthy with normal developmental milestones, without the presence of congenital malformations or adverse effects. Lack of information on safety data regarding the use of new antipsychotic formulations remains important in treating women with mental illness who desire to become pregnant. Further studies in this clinical population with a larger number of patients included remains necessary.

Abstract
Objectives: Food cravings may cause weight gain in patients with schizophrenia. This study investigated psychological characteristics associated with food cravings in patients with first-episode psychosis. Methods: This study analyzed data from a clinical cohort of first-episode psychosis patients taking antipsychotics for 3 months or less. The strength of food cravings was measured using the General Food Cravings Questionnaire-Trait (G-FCQ-T). Psychological characteristics and psychiatric symptoms were investigated with the Positive and Negative Symptom Scale (PANSS), Calgary Depression Scale for Schizophrenia (CDSS), Social and Occupational Functioning Assessment Scale, Rosenberg Self-Esteem Scale (RSES), and Perceived Stress Scale (PSS). Clinical characteristics were compared according to significant weight gain (≥10% increase in body weight compared to baseline) over 3 months. Associations between the G-FCQ-T and other psychiatric scales were investigated. We conducted sex-stratified analyses. Results: In total, 182 patients (78 males and 104 females) with first-episode psychosis were enrolled in this study. In females, the G-FCQ-T total score at baseline was associated with baseline body weight and significant weight gain over 3 months. The PSS scales were significantly associated the G-FCQ-T total and all subscale scores in female participants. Scores on the RSES and CDSS were significantly associated with the G-FCQ-T total score and with the preoccupation and loss of control subscale scores. The PANSS negative and general subscales were significantly associated with the positive outcome expectancy and loss of control subscales of the G-FCQ-T, respectively. In males, the only significant association was between the loss of control subscale and RSES scores. Linear regression analysis showed significant associations of PSS scores with the total and all subscale scores of the G-FCQ-T despite the loss of significance for other variables. Conclusion: These results indicate that the food cravings in patients with first-episode psychosis, which were associated with weight gain, were influenced by perceived stress in females. To reduce food cravings in female patients with schizophrenia, interventions aimed at perceived stress should be considered.

Abstract
OBJECTIVE A combination of olanzapine and the opioid receptor antagonist samidorphan is under development for the treatment of schizophrenia and bipolar I disorder. The single-tablet combination treatment is intended to provide the efficacy of olanzapine while mitigating olanzapine-associated weight gain. In this phase 3 double-blind trial, the authors evaluated the weight profile of combined olanzapine/samidorphan compared with olanzapine in patients with schizophrenia. METHODS Adults (ages 18‒55 years) with schizophrenia were randomly assigned to receive either combination treatment with olanzapine and samidorphan or olanzapine treatment for 24 weeks. Primary endpoints were percent change from baseline in body weight and proportion of patients with ≥10% weight gain at week 24. The key secondary endpoint was the proportion of patients with ≥7% weight gain. Waist circumference and fasting metabolic laboratory parameters were also measured. RESULTS Of 561 patients who underwent randomization (olanzapine/samidorphan combination, N=280; olanzapine, N=281), 538 had at least one postbaseline weight assessment. At week 24, the least squares mean percent weight change from baseline was 4.21% (SE=0.68) in the olanzapine/samidorphan group and 6.59% (SE=0.67) in the olanzapine group (the difference of -2.38% [SE=0.76] was significant). Significantly fewer patients in the olanzapine/samidorphan combination group compared with the olanzapine group had weight gain ≥10% (17.8% and 29.8%, respectively; number needed to treat [NNT]=7.29; odds ratio=0.50) and weight gain ≥7% (27.5% and 42.7%, respectively; NNT=6.29; odds ratio=0.50). Increases in waist circumference were smaller in the olanzapine/samidorphan combination group compared with the olanzapine group. Schizophrenia symptom improvement was similar between treatment groups. Adverse events (in ≥10% of the groups) in the olanzapine/samidorphan and olanzapine groups included weight gain (24.8% and 36.2%), somnolence (21.2% and 18.1%), dry mouth (12.8% and 8.0%), and increased appetite (10.9% and 12.3%). Metabolic changes were small and similar between treatments. CONCLUSIONS Olanzapine/samidorphan combination treatment was associated with significantly less weight gain and smaller increases in waist circumference than olanzapine and was well tolerated. The antipsychotic efficacy of the combination treatment was similar to that of olanzapine monotherapy.

Pharmacol Biochem Behav 2020; 199:173064. [PMID: 33127383 DOI: 10.1016/j.pbb.2020.173064] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2020] [Revised: 09/30/2020] [Accepted: 10/23/2020] [Indexed: 01/02/2023]
Abstract
Risperidone use in children and adolescents is associated with the development of metabolic disorders including increased accumulation of body fat, dyslipidemia, and glucose and insulin metabolism dysregulation. As pharmacological interventions are often limited in their ability to treat a range of side-effects, this study aimed to evaluate the effectiveness of daily voluntary exercise intervention to prevent metabolic side-effects induced by risperidone in juveniles. Thirty-two juvenile female Sprague Dawley rats were treated with risperidone (0.9 mg/kg; b.i.d; n = 16) or vehicle (0.3 g cookie dough pellet; n = 16). These rats were then assigned to a sedentary or voluntary exercise intervention (three hours daily access to running wheels) group (n = 8/group) for a period of four weeks. An intra-peritoneal glucose tolerance test was performed after three weeks of risperidone treatment and exercise intervention to assess glucose tolerance. During the exercise intervention, risperidone-treated rats ran significantly less than vehicle-treated rats. Risperidone treatment of sedentary rats resulted in significantly increased white adipose tissue, fasting triglyceride and fasting insulin compared to vehicle-treated sedentary rats. Exercise intervention of risperidone-treated rats prevented significant increases in these metabolic parameters compared to risperidone-treated sedentary rats. These results support voluntary exercise as an effective mitigator of metabolic side-effects associated with risperidone treatment in juvenile rats. Dyslipidemia and dysregulation of glucose and insulin metabolism are significant risk factors for morbidities and mortality later in life, therefore a focus on strategies to mitigate these adverse effects is critical. Our findings support clinical trials in exercise intervention to prevent metabolic disorders associated with antipsychotic medication in children and adolescents.

Metabolomic profiles associated with a mouse model of antipsychotic-induced food intake and weight gain. Sci Rep 2020; 10:18581. [PMID: 33122657 PMCID: PMC7596057 DOI: 10.1038/s41598-020-75624-2] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2020] [Accepted: 10/09/2020] [Indexed: 12/12/2022] Open
Abstract
Antipsychotic drugs (AP) are used to treat a multitude of psychiatric conditions including schizophrenia and bipolar disorder. However, APs also have metabolic side effects including increased food intake and body weight, but the underlying mechanisms remain unknown. We previously reported that minocycline (MINO) co-treatment abrogates olanzapine (OLZ)-induced hyperphagia and weight gain in mice. Using this model, we investigated the changes in the pharmacometabolome in the plasma and hypothalamus associated with OLZ-induced hyperphagia and weight gain. Female C57BL/6 mice were divided into groups and fed either i) control, CON (45% fat diet) ii) CON + MINO, iii) OLZ (45% fat diet with OLZ), iv) OLZ + MINO. We identified one hypothalamic metabolite indoxylsulfuric acid and 389 plasma metabolites (including 19 known metabolites) that were specifically associated with AP-induced hyperphagia and weight gain in mice. We found that plasma citrulline, tricosenoic acid, docosadienoic acid and palmitoleic acid were increased while serine, asparagine and arachidonic acid and its derivatives were decreased in response to OLZ. These changes were specifically blocked by co-treatment with MINO. These pharmacometabolomic profiles associated with AP-induced hyperphagia and weight gain provide candidate biomarkers and mechanistic insights related to the metabolic side effects of these widely used drugs.

Abstract
Weight gain is a common consequence of treatment with antipsychotic drugs in early psychosis, leading to further morbidity and poor treatment adherence. Identifying tools that can predict weight change in early psychosis may contribute to better-individualised treatment and adherence. Recently we showed that proteomic profiling with sequential window acquisition of all theoretical fragment ion spectra (SWATH) mass spectrometry (MS) can identify individuals with pre-diabetes more likely to experience weight change in relation to lifestyle change. We investigated whether baseline proteomic profiles predicted weight change over time using data from the BeneMin clinical trial of the anti-inflammatory antibiotic, minocycline, versus placebo. Expression levels for 844 proteins were determined by SWATH proteomics in 83 people (60 men and 23 women). Hierarchical clustering analysis and principal component analysis of baseline proteomics data did not reveal distinct separation between the proteome profiles of participants in different weight change categories. However, individuals with the highest weight loss had higher Positive and Negative Syndrome Scale (PANSS) scores. Our findings imply that mode of treatment i.e. the pharmacological intervention for psychosis may be the determining factor in weight change after diagnosis, rather than predisposing proteomic dynamics.

Early Intervention in Psychosis: Effectiveness and Implementation of a Combined Exercise and Health Behavior Intervention Within Routine Care. Front Endocrinol (Lausanne) 2020; 11:577691. [PMID: 33193094 PMCID: PMC7649318 DOI: 10.3389/fendo.2020.577691] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2020] [Accepted: 09/30/2020] [Indexed: 12/20/2022] Open
Abstract
Aim Young people with psychosis have higher rates of obesity, premature cardiovascular disease, and death compared to non-psychotic peers in the general population due to changes in metabolic regulation linked to antipsychotic medication and adverse health risk behaviors. The aim of this paper is to outline the development, implementation, and evaluation of a combined 12-week exercise and health behavior intervention delivered as part of an Early Intervention in Psychosis (EIP) routine service, within the UK. Methods Participants (n = 27) completed a 12-week combined intervention program, engaging in weekly, 90-min sessions comprising a healthy behavior education session (45 min), followed by a facilitated exercise session (45 min). Anthropometric data from participants (n = 26) were collected at baseline, 12 weeks, and 12 months post-intervention. Health behaviors and clinical measurements were assessed at baseline and 12 months. Results Mean baseline data suggests participants were at an increased health risk on entry to the program, with elevated values in mean body mass index (BMI; 70% overweight/obese), waist circumference, resting heart rate, and triglycerides. Fifty percent reported smoking daily, 64% ate < 5 fruits/vegetables per day, and 52% of participants were prescribed highly obesogenic antipsychotic medications (i.e., Olanzapine). At 12 weeks and 12 months, no changes were observed in mean BMI, waist circumference or any other clinical variable (p > 0.05). At 12 months, participants reported a positive impact on health behaviors including improved diet, increased physical activity levels, and cessation of substance use (n = 2), alcohol use (n = 2), and smoking (n = 4). Focus groups captured participant experiences, engagement with and satisfaction with the program, including challenges/barriers to program adherence. Conclusions The 12-week exercise and health behaviors program supported participants to attenuate their physical health risk which was sustained at 12-month follow-up. Self-reported positive health behavior changes are likely to have contributed to the prevention of excessive weight gain in this high-risk period. The evaluation was designed to have validity for a "real world EIP setting" and reflect the complexity of delivery to this participant group. Evaluation findings influenced subsequent commissioning of the physical health intervention as an ongoing element of routine EIP care within the participant site.

Abstract
BACKGROUND Clozapine remains the only medication licensed for treating refractory schizophrenia. However, it remains underutilized in part due to concerns regarding adverse events. SOURCES OF DATA Published literature. AREAS OF AGREEMENT Common adverse events during clozapine treatment include sedation, hypersalivation, postural hypotension, dysphagia, gastrointestinal hypomotility, weight gain, diabetes mellitus and dyslipidaemia. Rare but serious events include agranulocytosis, cardiomyopathy, myocarditis, pneumonia, paralytic ileus and seizure. AREAS OF CONTROVERSY It remains unclear how best to minimize clozapine-induced morbidity/mortality (i) during dose titration, (ii) from hypersalivation and (iii) from gastrointestinal hypomotility. It is also unclear how clozapine pharmacokinetics are affected by (i) gastrointestinal hypomotility, (ii) systemic infection and (iii) passive exposure to cigarette smoke. Whether monthly haematological monitoring needs to continue after 12 months of uninterrupted therapy is also a subject of debate. GROWING POINTS There is a need for better management of serious clozapine-related adverse events in addition to agranulocytosis. There is also a need for better education of patients and carers, general practitioners, A&E and ITU staff and others of the problems posed in using clozapine safely. AREAS TIMELY FOR DEVELOPING RESEARCH There is a need for more research on assessing clozapine dosage (i) as patients get older, (ii) with respect to exposure to cigarette smoke and (iii) optimizing response if adverse events or other factors limit dosage.

Abstract
Schizophrenia significantly limits social functioning with positive and negative symptoms and cognitive dysfunction. Blonanserin (LONASEN®), a novel second-generation antipsychotic approved for treating schizophrenia in Japan in 2008, reportedly shows beneficial effects on cognitive function as well as positive and negative symptoms, with potential for improving social functioning. To understand the safety and effectiveness of blonanserin in the real clinical practice, five Japanese post-marketing surveillances have been conducted and published to date. In this article, we reviewed all the Japanese post-marketing surveillances and discussed the clinical usefulness of blonanserin in patients with schizophrenia having diverse clinical characteristics. Adverse drug reactions, such as akathisia and extrapyramidal symptoms, were common in all surveillances. However, those specific to second-generation antipsychotics, such as weight gain and abnormalities in glycometabolism or lipid metabolism, were rarely observed. In addition, no adverse drug reactions apart from clinical trial results were found. Brief Psychiatric Rating Scale total scores in all surveillances significantly lowered at the last evaluation than at baseline. These results were consistent through 1-year of treatment, suggesting that effectiveness is maintained even after long-term use. In conclusion, blonanserin is considered a beneficial drug in real clinical practice for patients with schizophrenia having diverse characteristics.

Abstract
Objective: Only few psychotropic drugs are approved to treat tic disorders. The aim was to describe use of tic-suppressing medication and other psychotropic drugs in children with tics. Methods: Using nationwide registries, we identified children receiving a tic diagnosis in Denmark during 2006-2017 and extracted data on tic-suppressing medication and other psychotropic drugs. Results: Antipsychotics were used by 12%. Use of tic-suppressing medication increased with age and varied according to sex. Over time less children with tics were medicated (from 44% to 38% in the total use of psychotropic drugs) mainly due to decreased use of antipsychotics (from 18% to 6.4%). In recent years, use of aripiprazole exceeded that of risperidone (38% vs. 35%), although risperidone was most often first choice (34%) followed by aripiprazole (22%). Most children stayed on their initial treatment. Attention-deficit/hyperactivity disorder medication (27%) was the most common additional psychotropic drug class used. Regional variations were found in the treatment of tics. Hospital specialists were mainly responsible for treatment. Conclusions: Most children with tics do not use tic-suppressing or other psychotropic drugs. The use of aripiprazole superseded risperidone, however risperidone remains the most common first-choice treatment. Treatment was mainly handled by specialists, which is reassuring given the lack of national guidelines, however, regional variations merit further attention as do the variation in treatment between young girls and boys.

Recruited physicians completed a patient record form (PRF) for their first 10 consulted schizophrenia patients aged ≥18. These patients voluntarily completed a patient self-completion form (PSC). Compliance was measured by subjective physician assessment. Drivers of and outcomes associated with compliance were identified by regression analyses. Results A total of 150 physicians completed PRFs for 1489 patients (706 sometimes compliant (SC), 636 always compliant (AC)). A total of 680 patients completed a PSC (327 SC, 295 AC). AC patients were less likely to be male (52.2% vs. 58.6%; P = 0.021) and unemployed (odds ratio (OR) 0.91, 95% confidence interval (CI) 0.82-1.00; P < 0.001) or to have had a treatment regimen change (OR 0.56, 95% CI 0.40-0.80; P = 0.001) than SC patients. AC patients were less likely to have had more comorbidities (OR 0.91, 95% CI 0.82-1.00; P = 0.045) and hospitalizations in the past 12 months (OR 0.59, 95% CI 0.43-0.80; P = 0.001) than SC patients. Overall, AC patients had better clinical and humanistic outcomes. Weight gain was a common side effect for all patients; SC patients with weight gain had poorer outcomes than those without weight gain. Conclusion Schizophrenia patients that were SC experienced poorer clinical outcomes and quality of life. Weight gain may exacerbate these poorer outcomes.

Early Interv Psychiatry 2020; 14:428-438. [PMID: 31515972 PMCID: PMC7384107 DOI: 10.1111/eip.12868] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2018] [Revised: 02/19/2019] [Accepted: 08/06/2019] [Indexed: 01/08/2023]
Abstract
AIM This exploratory post hoc analysis of a randomized, double-blind (DB), multicentre, non-inferiority study (NCT01515423) evaluated the effects of the long-acting injectable antipsychotic therapies once-monthly paliperidone palmitate (PP1M) and once-every-3-months paliperidone palmitate (PP3M) on symptom severity and functional remission in patients with schizophrenia with differing durations of illness (≤5, 6-10 and >10 years). METHODS Endpoints included Personal and Social Performance (PSP) scale and Positive and Negative Syndrome Scale (PANSS) total scores during the DB phase (DB baseline and DB endpoint) and the proportion of patients meeting PSP or PANSS remission criteria at any time during the open-label (OL) or DB phases that were maintained for ≥3, ≥6, ≥9 or ≥12 months. RESULTS In both the OL and DB phases, significant improvements in PSP scale and PANSS scores were observed from baseline in all duration-of-illness groups, with significantly greater improvements observed in the ≤5-year and 6-10-year groups compared with the >10-year group. The proportion of patients who maintained PSP or PANSS remission criteria for ≥3, ≥6, ≥9 and ≥12 months was higher in the ≤5-year and 6-10-year groups than in the >10-year group. Safety profiles were similar across duration-of-illness groups in the DB phase. CONCLUSIONS Symptomatic and functional improvements were observed with PP1M/PP3M in patients with differing durations of schizophrenia, but the magnitude of the effects was greater in those with early illness vs chronic illness. These findings advocate implementation of PP1M and PP3M in all stages of schizophrenia, including early illness.

Abstract
Current antipsychotics have limited efficacy in controlling cognitive and negative symptoms of schizophrenia (SZ). Glutamatergic dysregulation has been implicated in the pathophysiology of SZ, based on the capacity of N-methyl-D-aspartate receptor (NMDAR) antagonists such as ketamine (KET) to induce SZ-like behaviors. This could be related to their putative neuropathological effect on gamma-aminobutyric (GABAergic) interneurons expressing parvalbumin (PV), which would lead to a hyperglutamatergic condition. Metabotropic glutamate receptor 2 (mGluR2) negatively modulates glutamate release and has been considered a potential clinical target for novel antipsychotics drugs. Our aim was to evaluate the efficacy of JNJ-46356479 (JNJ), a positive allosteric modulator (PAM) of the mGluR2, in reversing neuropathological and behavioral deficits induced in a postnatal KET mice model of SZ. These animals presented impaired spontaneous alternation in the Y-maze test, suggesting deficits in spatial working memory, and a decrease in social motivation and memory, assessed in both the Three-Chamber and the Five Trial Social Memory tests. Interestingly, JNJ treatment of adult mice partially reversed these deficits. Mice treated with KET also showed a reduction in PV+ in the mPFC and dentate gyrus together with an increase in c-Fos expression in this hippocampal area. Compared to the control group, mice treated with KET + JNJ showed a similar PV density and c-Fos activity pattern. Our results suggest that pharmacological treatment with a PAM of the mGluR2 such as JNJ could help improve cognitive and negative symptoms related to SZ.

Abstract
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. Results: Patients (n = 225), parents (n = 128), and clinicians (n = 54) reported weight gain as the most concerning SGA-related side effect (45.6%, 38.9%, and 70.4%, respectively). Weight gain was also the top adherence barrier for patients (35.9%), but was ranked fourth (41.8%) by parents. Patients (61.5%) were more likely "definitely" willing to co-initiate another medication to manage weight gain upon SGA initiation than parents (20.1%) or clinicians (1.9%). Conversely, parents (54.9%) and clinicians (84.9%) were "definitely" willing to accept/prescribe a second medication aiming to reverse weight gain of ≥10 lbs., and patients (61.1%) were willing to add another medication to reverse any weight gain. Conclusion: SGA-related weight gain impairs medication adherence in young patients with bipolar disorder. Many young patients would start pharmacologic treatment to mitigate SGA-related weight gain at treatment initiation, parents and clinicians are more hesitant. This research informs patient-centered perspectives on SGA adherence barriers and strategies to minimize potential side effects, which may improve adherence in this vulnerable patient population.

Severe weight gain as an adverse drug reaction of psychotropics: Data from the AMSP project between 2001 and 2016. Eur Neuropsychopharmacol 2020; 36:60-71.

Abstract
Severe weight gain induced by psychotropics is a known problem in psychiatry. Various drugs from different classes may lead to weight gain that may further lead to potentially life-shortening diseases, such as diabetes or cardiovascular disease. A total of 344 cases of severe weight gain (>10% of body weight) have been documented by the drug safety in psychiatry program AMSP between 2001 and 2016. Patients gained 12.7 ± 5.5 kg weight within 12±15 weeks. This equals a Body Mass Index (BMI) gain of 4.4 ± 1.9 kg/m² to a final BMI of 28.8 ± 5.5 kg/m². In addition, 142 retrospective reports documented at admission have been analyzed. Within one year these patients gained 6.4 ± 4.0 kg/m² to a final BMI of 31.9 kg/m². The weight gain was extreme in some cases. For example, 35% of the patients gained more than 20 kg. On average the patients reached overweight or even adiposity. Only 27% of the patients could loose some weight at the end of their stay. This emphasizes the relevance of this long-term problem for the patients' health. Mostly second generation antipsychotics, and therein olanzapine, as well as antidepressants and anticonvulsants have been imputed. Severe weight gain is a slow process and it is rarely documented as adverse drug reaction under real-life conditions compared to the high percentage of patients with weight gain in clinical studies. It might often remain unnoticed due to shorter stationary treatment and changing treatment settings.

Abstract
BACKGROUND The present study reports a case series where three adolescent patients with anorexia nervosa (AN) (two cases with typical AN and one case atypical AN) received nasogastric tube feeding under restraint in line with new dietetic clinical guidelines. METHODS Three cases were chosen out of 61 admitted patients over the period of 1 year who were fed via a nasogastric tube under restraint in a specialist eating disorders unit for children and adolescents. These cases were chosen to highlight a range of clinical scenarios that clinicians may encounter. They also represent clinical scenarios where decisions to feed patients under restraint were rendered more complex by additional concerns. RESULTS Despite the complexity of the cases, all patients tolerated the feeds well and were discharged home eating solid food. CONCLUSIONS The decision to feed a patient against their will is never an easy one. Sadly, there have been some recent high-profile deaths of adult patients on medical wards where treatment opinion was not considered, and the patient received no or minimal nutrition when awaiting specialist treatment. Dietetic guidelines have been published to help inform clinicians for whom feeding under restraint may be out of the scope of their daily practice. This case series highlights clinical scenarios that illustrate the utility of the guidelines, which we hope will support clinicians when making, potentially lifesaving decisions in children and young people.

Abstract
BACKGROUND Differences between people with schizophrenia and psychiatrically healthy controls have been consistently demonstrated on measures of retinal function such as electroretinography (ERG), and measures of retinal structure such as optical coherence tomography (OCT). Since our 2015 review of this literature, multiple new studies have been published using these techniques. At the same time, the accumulation of data has highlighted the "fault lines" in these fields, suggesting methodological considerations that need greater attention in future studies. METHODS We reviewed studies of ERG and OCT in schizophrenia, as well as data from studies whose findings are relevant to interpreting these papers, such as those on effects of the following on ERG and OCT data: comorbid medical conditions that are over-represented in schizophrenia, smoking, antipsychotic medication, substance abuse, sex and gender, obesity, attention, motivation, and influences of brain activity on retinal function. RESULTS Recent ERG and OCT studies continue to support the hypothesis of retinal structural and functional abnormalities in schizophrenia, and suggest that these are relevant to understanding broader aspects of pathophysiology, neurodevelopment, and neurodegeneration in this disorder. However, there are differences in findings which suggest that the effects of multiple variables on ERG and OCT data need further clarification. CONCLUSIONS The retina, as the only component of the CNS that can be imaged directly in live humans, has potential to clarify important aspects of schizophrenia. With greater attention to specific methodological issues, the true potential of ERG and OCT as biomarkers for important clinical phenomena in schizophrenia should become apparent.

Abstract
BACKGROUND Imbalances in metal concentrations have been suggested to contribute to the pathophysiology of different brain disorders, such as bipolar disorder (BD) and schizophrenia (SCZ). OBJECTIVES The aim of this exploratory study is to evaluate the association between the concentrations of macro/trace elements in serum from BD and SCZ patients considering the effects from different treatments. METHODS Eleven subjects with SCZ, seven with BD treated with lithium (BDL) and eight subjects with BD treated with other medications except lithium (BDN) were recruited for the study, as well as eleven healthy controls (HC). Serum concentrations of eleven macro/trace elements (Se, Zn, Fe, K, Ca, Mg, P, Al, Cu, Mn, and Ni) were determined using inductively coupled plasma mass spectrometry (ICP-MS). RESULTS Se and Zn concentrations were significantly lower for patients with SCZ and BD in comparison to HC by one-way ANOVA test. Moreover, serum concentrations for Fe were significantly higher (p < 0.05) in BDN (548 ± 92 μg L-1) and SCZ (632 ± 279 μg L-1) in comparison to HC (421 ± 121 μg L-1). A significant negative correlation was reported between Se and Fe in BDL group (r = -0.935, p < 0.05). In addition, a significantly higher Cu/Zn ratio was determined in SCZ group against HC (ratio = 2.4, p = 0.028). CONCLUSIONS The obtained results suggest that the imbalance in Fe concentrations is an effect of BD treatment. Lithium is supposed to have an antagonist effect for Se in BDL patients. A negative correlation reported between Fe and BMI in SCZ group could be related to antipsychotic treatment and the Cu/Zn ratio reported could be considered as a suggesting parameter to relate oxidative stress to SCZ. Future studies including larger number of patients with SCZ and BD before and after treatment are necessary to confirm the investigative results presented herein.

Abstract
Second-generation antipsychotic-related weight gain and metabolic disturbances are a major public health issue given the widespread prescribing of these medications. The lack of clearly known mechanisms of cardiometabolic adverse effects and the relevance of cardiometabolic health for survival make this an important area for research. While nonpharmacologic and some pharmacologic treatments have shown benefits vs control conditions or placebo, the effects are modest and long-term benefits are less clear. Therefore, new approaches to mitigate second-generation antipsychotic-associated cardiometabolic burden are sorely needed.

Abstract
BACKGROUND Cardiovascular (CV) disease is the leading cause of death for people with serious mental illness (SMI), but clinicians are often slow to address this risk. METHODS/DESIGN 78 Midwestern primary care clinics were randomized to receive or not receive access to a clinical decision support (CDS) tool. Between March 2016 and September 2018, primary care clinicians (PCPs) received CDS alerts during visits with adult patients with SMI who met minimal inclusion criteria and had at least one CV risk factor not at goal. The PCP CDS included a summary of six modifiable CV risk factors and patient-specific treatment recommendations. Psychiatrists received CDS alerts during their next visit with an eligible patient with SMI that alerted them to an elevated body mass index or recent weight gain and the presence of an obesogenic SMI medication. Study outcomes include total modifiable CV risk, six modifiable CV risk factors, and use of obesogenic SMI medications. DISCUSSION This cluster-randomized pragmatic trial allowed PCPs and psychiatrists the opportunity to improve CV risk in a timely manner for patients with SMI. Effectiveness will be assessed using an intent-to-treat analysis, and outcomes will be assessed largely through electronic health record data harvested by the CDS tool itself. In total, 10,347 patients with SMI had an index primary care visit in a randomized clinic, and 8937 patients had at least one follow-up visit. Analyses are ongoing, and trial results are expected in mid-2020. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02451670.

Neuropsychopharmacol Rep 2020; 40:63-72. [PMID: 31788985 PMCID: PMC7292214 DOI: 10.1002/npr2.12089] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2019] [Revised: 11/04/2019] [Accepted: 11/05/2019] [Indexed: 12/20/2022] Open
Abstract
OBJECTIVE To report the efficacy and safety of blonanserin in patients with schizophrenia compared with risperidone in a Japanese multicenter, randomized, double-blind study based on post hoc sensitivity analysis in addition to the previous results reported by Miura and discuss the current approaches for schizophrenia treatment. METHODS Of 302 patients randomized, 156 received blonanserin (8-24 mg/d) and 145 received risperidone (2-6 mg/d) for 8 weeks. Efficacy variables included the Positive and Negative Syndrome Scale (PANSS) total score for the primary outcome, PANSS subscale, Brief Psychiatric Rating Scale (BPRS), and Clinical Global Impression-Improvement (CGI-I) for secondary outcomes. Safety variables included treatment-emergent adverse events, Drug Induced Extrapyramidal Symptoms Scale scores, laboratory data, vital signs, electrocardiogram, etc RESULTS: Blonanserin was not inferior to risperidone in the change in PANSS total score at a non-inferior margin of -7 (intergroup difference, -0.46; 95% CI, -4.40 to 3.48). Post hoc analyses wholly supported the primary result. No major difference was found in the changes in BPRS scores and the improvement rate on CGI-I between the drugs. The incidence of adverse events was similar in the two drugs. Blonanserin was associated with a lower risk of prolactin increase, weight gain, and orthostatic hypotension compared with risperidone. However, blonanserin was associated with a higher incidence of akathisia and excitability compared with risperidone. Most of the adverse events were mild to moderate in severity with no specific events of predominant high severity in the both drugs. CONCLUSIONS Blonanserin exerted the similar efficacy to risperidone in both positive and negative symptoms in schizophrenia with a lower risk of prolactin increase, weight gain, and orthostatic hypotension compared with risperidone. Blonanserin will serve as a favorable treatment option for schizophrenia in daily clinical practice.

Abstract
BACKGROUND Clozapine is more effective than other atypical antipsychotics for treatment resistant schizophrenia, but has serious side effects. Clozapine has an estimated cumulative seizure risk of 10% in patients treated for 3.8 years. Bupropion can also induce seizures and its estimated risk is 0.4% at recommended doses. While some risk factors for seizures are known, much remains unknown about predicting seizure risk. Cases: We present 2 cases of seizures in patients treated with clozapine and bupropion without a seizure history. In the first case, a patient with schizoaffective disorder treated with dual antipsychotic therapy had a witnessed generalized tonic-clonic seizure. With the exception of bupropion/naltrexone which was started 2.5 months prior for weight loss, she had not had any recent medication changes. In the second case, a patient with schizoaffective disorder was treated with clozapine and was prescribed bupropion SR for smoking cessation for an extended duration. He had cut back on cigarette use in the 2 months prior to reporting "spells." The neurologist's assessment was probable epileptic seizures which resolved after the bupropion was stopped and divalproex was started for seizure prophylaxis. CONCLUSION Clozapine and bupropion are known to lower the seizure threshold, but little information is available regarding the risk when used in combination. It is unclear whether these agents, when used in combination, have additive seizure risk or possible synergistic effects. Bupropion should be used cautiously in patients treated with clozapine. Safer agents that do not lower the seizure threshold should be utilized whenever possible.
