Fourteen-year trends in prescribing patterns for patients with bipolar mania discharged from a public psychiatric hospital in Taiwan

Bipolar disorder is a complex mental illness. Pharmacological therapy, including antipsychotics and mood stabilizers, is the primary treatment approach for manic episode. The study aimed to analyze prescribing patterns over a 14-year period for patients with bipolar mania discharged from a psychiatric hospital in Taiwan. Patients with bipolar mania discharged from the study hospital between 2006 and 2019 (n = 2956) were included in the analysis. Prescribed drugs for the treatment of manic episode, included mood stabilizers (i.e., lithium, valproate, carbamazepine) and any antipsychotics (i.e., second- and first-generation antipsychotics; SGAs & FGAs). Monotherapy, simple polypharmacy, and complex polypharmacy were also examined. Simple polypharmacy was defined as being prescribed 2 different bipolar drugs (lithium, valproate, carbamazepine, and any antipsychotics), while complex polypharmacy at least 3 bipolar drugs. Temporal trends of each prescribing pattern were analyzed using the Cochran-Armitage Trend test. The prescription rates of valproate, SGAs, and complex polypharmacy significantly increased over time, whereas the prescription rates of any mood stabilizers, FGAs, and simple polypharmacy significantly decreased. Prescription rates of lithium and monotherapy did not significantly change. The study highlights the shifts in prescribing practices for bipolar mania. SGAs were prescribed more while FGAs declined, likely due to SGAs' favorable properties. Complex polypharmacy increased, reflecting the complexity of treating bipolar disorder. Long-term outcomes of these changes require further research.

Modulation of Leucine Sensors to Mitigate Antipsychotics-Induced Metabolic Syndrome: A New Vista

Second-generation antipsychotics (SGAs) are currently the mainstay in the pharmacotherapy of some psychiatric disorders, which have improved the quality of life of millions of patients globally. A broad spectrum of activity and diminished liabilities of extrapyramidal side effects have made SGAs better alternatives compared to first-generation antipsychotics. Nevertheless, they display a complex profile of activity by affecting an array of biological targets and, as a result, are associated with a constellation of metabolic abnormalities such as hyperglycemia, dyslipidemia, weight gain, and cardiovascular problems. The SGAs-induced metabolic syndrome's exact mechanism has remained nebulous, but some evidence points the finger at mTOR signaling. In this viewpoint, we propose potential strategies to prevent or alleviate the SGA-induced metabolic adverse effects by modulating the activity of the leucine sensors, Sestrins.

Priapism in a 31-Year-Old Male With Paranoid Schizophrenia

Priapism is a painful and emergent side effect that has been linked to some antipsychotics and other psychiatric medications, most often trazodone. This is thought to be due to some level of alpha-1 adrenergic blockade by these medications. Aripiprazole is an atypical antipsychotic with notably weak alpha-1 adrenergic antagonism. Thus, we report on a unique case of aripiprazole-induced priapism in a patient with schizophrenia and recurrent episodes of antipsychotic-induced priapism. This study offers insight into the potential mechanism of aripiprazole-induced priapism and offers alternative medications, such as olanzapine and lumateperone, to treat the patient's ongoing psychotic disorder.

Treatment-resistant depression: definition, prevalence, detection, management, and investigational interventions

Treatment-resistant depression (TRD) is common and associated with multiple serious public health implications. A consensus definition of TRD with demonstrated predictive utility in terms of clinical decision-making and health outcomes does not currently exist. Instead, a plethora of definitions have been proposed, which vary significantly in their conceptual framework. The absence of a consensus definition hampers precise estimates of the prevalence of TRD, and also belies efforts to identify risk factors, prevention opportunities, and effective interventions. In addition, it results in heterogeneity in clinical practice decision-making, adversely affecting quality of care. The US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) have adopted the most used definition of TRD (i.e., inadequate response to a minimum of two antidepressants despite adequacy of the treatment trial and adherence to treatment). It is currently estimated that at least 30% of persons with depression meet this definition. A significant percentage of persons with TRD are actually pseudo-resistant (e.g., due to inadequacy of treatment trials or non-adherence to treatment). Although multiple sociodemographic, clinical, treatment and contextual factors are known to negatively moderate response in persons with depression, very few factors are regarded as predictive of non-response across multiple modalities of treatment. Intravenous ketamine and intranasal esketamine (co-administered with an antidepressant) are established as efficacious in the management of TRD. Some second-generation antipsychotics (e.g., aripiprazole, brexpiprazole, cariprazine, quetiapine XR) are proven effective as adjunctive treatments to antidepressants in partial responders, but only the olanzapine-fluoxetine combination has been studied in FDA-defined TRD. Repetitive transcranial magnetic stimulation (TMS) is established as effective and FDA-approved for individuals with TRD, with accelerated theta-burst TMS also recently showing efficacy. Electroconvulsive therapy is regarded as an effective acute and maintenance intervention in TRD, with preliminary evidence suggesting non-inferiority to acute intravenous ketamine. Evidence for extending antidepressant trial, medication switching and combining antidepressants is mixed. Manual-based psychotherapies are not established as efficacious on their own in TRD, but offer significant symptomatic relief when added to conventional antidepressants. Digital therapeutics are under study and represent a potential future clinical vista in this population.

Longitudinal Gut Microbiota Dysbiosis Underlies Olanzapine-Induced Weight Gain

Olanzapine is one of the most effective medicines available for stabilizing schizophrenia spectrum disorders. However, it has been reported to show the greatest propensity for inducing body weight gain and producing metabolic side effects, which cause a great burden in patients with psychiatric disorders. Since the gut microbiota has a profound impact on the initiation and development of metabolic diseases, we conducted a longitudinal study to explore its role in olanzapine-induced obesity and metabolic abnormalities. Female Sprague-Dawley rats were treated with different doses of olanzapine, and metabolic and inflammatory markers were measured. Olanzapine significantly induced body weight gain (up to a 2.1-fold change), which was accompanied by hepatic inflammation and increased plasma triglyceride levels (up to a 2.9-fold change), as well as gut microbiota dysbiosis. Subsequently, fuzzy c-means clustering was used to characterize three clusters of longitudinal trajectories for microbial fluctuations: (i) genera continuing to increase, (ii) genera continuing to decrease, and (iii) genera temporarily changing. Among them, Enterorhabdus (r = 0.38), Parasutterella (r = 0.43), and Prevotellaceae UCG-001 (r = 0.52) positively correlated with body weight gain. In addition, two MetaCyc metabolic pathways were identified as associated with olanzapine-induced body weight gain, including the superpathway of glucose and xylose degradation and the superpathway of l-threonine biosynthesis. In conclusion, we demonstrate that olanzapine can directly alter the gut microbiota and rapidly induce dysbiosis, which is significantly associated with body weight gain. This may suggest gut microbiota targets in future studies on metabolic abnormalities caused by olanzapine. IMPORTANCE Olanzapine is one of the most effective second-generation antipsychotics for stabilizing schizophrenia spectrum disorders. However, olanzapine has multiple drug-induced metabolic side effects, including weight gain. This study provides insight to the gut microbiota target in olanzapine-induced obesity. Specifically, we explored the longitudinal gut microbiota trajectories of female Sprague-Dawley rats undergoing olanzapine treatment. We showed that olanzapine treatment causes a dynamic alteration of gut microbiota diversity. Additionally, we identified three genera, Parasutterella, Enterorhabdus, and Prevotellaceae UCG-001, that may play an important role in olanzapine-induced obesity. In this case, the supply or removal of specific elements of the gut microbiota may represent a promising avenue for treatment of olanzapine-related metabolic side effects.

Pathophysiology and management of risperidone-induced sialorrhea: case report

Background

Among antipsychotics, sialorrhea is most associated with clozapine, and when it occurs, it is uncomfortable, socially stigmatizing, and can contribute to medication non-adherence. Risperidone has a generally negligible muscarinic activity compared to clozapine, and yet, multiple reports of severe sialorrhea associated with risperidone have been reported.

Case presentation

This case report describes risperidone-induced sialorrhea that was unintentionally masked by simultaneous clonidine administration that was intended to treat hypertension. Interestingly, sialorrhea was present but mild when clonidine was present; however, when risperidone was further titrated and clonidine removed, a significant worsening of sialorrhea developed. Sialorrhea did not respond to treatment with anticholinergic medication.

Conclusion

The pathophysiology of antipsychotic-induced sialorrhea is complex and varies between antipsychotics. Risperidone-induced sialorrhea is suspected of having prominent adrenergic pathophysiology that is likely composed of highly viscoelastic saliva (high protein content), differing from the more commonly encountered clozapine-induced sialorrhea. Risperidone-induced sialorrhea is reported as more likely to respond to dose reduction and treatment with α2-adrenergic receptor agonists or β-adrenergic receptor antagonists and less likely to respond to anticholinergic (antimuscarinic) medications.

Prevention of First-Episode Psychosis in People at Clinical High Risk: A Randomized Controlled, Multicentre Trial Comparing Cognitive-Behavioral Therapy and Clinical Management Plus Low-Dose Aripiprazole or Placebo (PREVENT)

BACKGROUND

There is limited knowledge of whether cognitive-behavioral therapy (CBT) or second-generation antipsychotics (SGAs) should be recommended as the first-line treatment in individuals at clinical high risk for psychosis (CHRp).

HYPOTHESIS

To examine whether individual treatment arms are superior to placebo and whether CBT is non-inferior to SGAs in preventing psychosis over 12 months of treatment.

STUDY DESIGN

PREVENT was a blinded, 3-armed, randomized controlled trial comparing CBT to clinical management plus aripiprazole (CM + ARI) or plus placebo (CM + PLC) at 11 CHRp services. The primary outcome was transition to psychosis at 12 months. Analyses were by intention-to-treat.

STUDY RESULTS

Two hundred eighty CHRp individuals were randomized: 129 in CBT, 96 in CM + ARI, and 55 in CM + PLC. In week 52, 21 patients in CBT, 19 in CM + ARI, and 7 in CM + PLC had transitioned to psychosis, with no significant differences between treatment arms (P = .342). Psychopathology and psychosocial functioning levels improved in all treatment arms, with no significant differences.

CONCLUSIONS

The analysis of the primary outcome transition to psychosis at 12 months and secondary outcomes symptoms and functioning did not demonstrate significant advantages of the active treatments over placebo. The conclusion is that within this trial, neither low-dose aripiprazole nor CBT offered additional benefits over clinical management and placebo.

Personalized switching from oral to long-acting injectable second-generation antipsychotics in schizophrenia treatment using pharmacokinetic considerations

INTRODUCTION

Long-acting injectable (LAI) formulations of second-generation antipsychotics (SGA) are a mainstay in the treatment of schizophrenia-spectrum patients, and their use improves adherence and reduces relapse risk. Personalizing LAI-based therapy involves tailoring the transition from oral to LAIs based on individual and drug-related pharmacokinetic peculiarities.

AREAS COVERED

We discuss pharmacokinetic considerations as a cornerstone of a smooth transition from oral to LAI SGAs based on works identified using an updated search in PubMed and Embase in February 2023. Establishing the extent of antipsychotic exposure during oral SGA-treatment from the patient's SGA levels is often a more appropriate orientation method to choose the equivalent LAI dose than population-based data. Oral dose adjustment during LAI transition can also be guided by checking SGA levels before the LAI injection.

EXPERT OPINION

LAI SGAs may dominate the maintenance treatment of schizophrenia-spectrum disorders with increased use for other severe mental illnesses such as bipolar disorder. Spurring this trend is the development of newer formulations with longer injection intervals and increased administration ease, but transitioning from oral SGA remains a challenge. By understanding the pharmacokinetics of LAI formulations and measuring SGA levels during oral therapy, one can personalize/optimize the switch from oral SGAs to LAI counterparts.

Oral Dyskinesia in a Pediatric Patient Following Concurrent Use of Neuroleptics and Stimulants: Treatment Strategy Considerations to Avert Avoidable Adverse Side Effects

Withdrawal-emergent dyskinesia is a movement disorder that emerges following sudden discontinuation or rapid taper of antipsychotic medication. It is infrequently identified and typically resolves within a few weeks from symptom onset. This case report describes a unique case of reversible oral dyskinesia in a 13-year-old male in the context of concurrent neuroleptic withdrawal and stimulant titration. The extant literature describing tardive dyskinesia is well-established; however, few studies have thoroughly examined withdrawal-emergent dyskinesia and other tardive syndromes. This report highlights the importance of clinician awareness as far as the potential for extrapyramidal symptoms and withdrawal-emergent adverse effects in concomitant management of antipsychotics and stimulants in the child and adolescent populations and may help inform future treatment and management of disorders that would indicate the concurrent use of these psychotropics.

Atypical antipsychotics olanzapine and clozapine increase bone loss in female rats with experimental periodontitis

BACKGROUND AND OBJECTIVES

Periodontitis is a highly prevalent disease in psychiatric patients, including those undergoing symptomatic treatment with second-generation antipsychotics. Some of these drugs, such as clozapine (CLO) and olanzapine (OLA), have prominent metabolic effects such as weight gain, hyperglycemia, and dyslipidemia, which are risk factors for periodontitis. In addition to the metabolic effects, there are reports of changes in salivary flow, gingival bleeding, and caries. In this context, we aimed to evaluate if the metabolic effects of OLA and CLO alter periodontal parameters in an animal model of periodontitis without the environmental and psychosocial biases inherent to human diseases.

METHODS

In the first set of experiments, male and female adult Wistar rats received oral administration of CLO, OLA, or vehicle for 45 days. They were evaluated for body mass composition and weight gain, blood glucose parameters (fasting and glucose tolerance and insulin resistance tests), and lipid profile (HDL, total cholesterol, and triglycerides). In a second set of experiments, the same measurements were performed in female rats exposed to the antipsychotics for 45 days and ligature-induced periodontitis on the 30th day of treatment. Macroscopic measurements of exposed roots, microtomography in the furcation region of the first molar, and histological evaluation of the region between the first and second molars were evaluated to assess bone loss. Additionally, gingival measurements of myeloperoxidase activity and pro-inflammatory cytokine TNF-α were made.

RESULTS

Only females exposed to OLA had more significant weight gain than controls. They also exhibited differences in glucose metabolism. Ligature-induced periodontitis produced intense bone retraction without changing the density of the remaining structures. The bone loss was even higher in rats with periodontitis treated with OLA or CLO and was accompanied by a local increase in TNF-α caused by CLO. These animals, however, did not exhibit the same metabolic impairments observed for animals without periodontitis.

CONCLUSION

The use of clozapine and olanzapine may be a risk factor for periodontal disease, independent of systemic metabolic alterations.

Fourteen-year trends in the prescribing patterns of pediatric bipolar patients discharged from two public mental hospitals in Taiwan

INTRODUCTION

The management of pediatric bipolar disorder (PBD) requires pharmacotherapy to control acute symptoms, reduce relapse, prevent suicide, and improve psychosocial functioning. The purpose of this study was to investigate prescribing patterns among PBD patients discharged from two public mental hospitals in Taiwan, from 2006 to 2019.

METHODS

PBD patients discharged from the two study hospitals, from 1 January 2006 to 31 December 2019 (n = 420), were included in the analysis. Prescribed drugs at discharge, including mood stabilizers (i.e., lithium, valproate, carbamazepine, and lamotrigine), antipsychotics (i.e., second- and first-generation antipsychotics, SGAs and FGAs), and antidepressants, were explored. Complex polypharmacy was defined as the use of 3 or more agents among the prescribed drugs. Time trends of each prescribing pattern were analyzed using the Cochran-Armitage Trend test.

RESULTS

The most commonly prescribed psychotropic agents were SGAs (76.0%), followed by valproate (65.7%) and FGAs (24.8%). The prescription rates of SGAs, antidepressants, antidepressant plus antipsychotic, and antidepressant without mood stabilizer significantly increased over time, whereas the prescription rates of mood stabilizers, lithium, and FGAs significantly decreased.

DISCUSSIONS

Prescribing patterns changed greatly for PBD patients over time. However, much more evidence supporting the effectiveness of psychotropic agents in PBD patients is required.

Neurodevelopmental Disorders, Schizophrenia Spectrum Disorders and Catatonia: The "Iron Triangle" Rediscovered in a Case Report

Catatonia is a complex neuropsychiatric syndrome, occurring in the context of different psychiatric and neurodevelopmental disorders, in neurological and medical disorders, and after substance abuse or withdrawal. The relationship between Autism Spectrum Disorder (ASD), Schizophrenia Spectrum Disorders (SSDs) and catatonia has been previously discussed, with the three disorders interpreted as different manifestations of the same underlying brain disorder (the "Iron Triangle"). We discuss in this paper the diagnostic, clinical and therapeutic implications of this complex relationship in an adolescent with ASD, who presented an acute psychotic onset with catatonia, associated with mixed mood symptoms. Second-generation antipsychotics were used to manage psychotic, behavioral and affective symptoms, with worsening of the catatonic symptoms. In this clinical condition, antipsychotics may be useful at the lowest dosages, with increases only in the acute phases, especially when benzodiazepines are ineffective. Mood stabilizers with higher GABAergic effects (such as Valproate and Gabapentin) and Lithium salts may be more useful and well tolerated, given the frequent association of depressive and manic symptoms with mixed features.

Glucose and Lipid Profiles Predict Anthropometric Changes in Drug-Naïve Adolescents Starting Treatment with Risperidone or Sertraline: A Pilot Study

Psychiatric disorders are associated with cardiometabolic diseases, partly due to adverse drug effects with individual risk variabilities. Risperidone and sertraline are widely used for youths. Although they may be exposed to anthropometric changes, few data about this population exist. We evaluated the correlation between several blood parameters and body changes in a very small group of drug-naïve adolescents who had started risperidone or sertraline. We examined weight, waist circumference (WC), WC/height ratio and body mass index (BMI) at baseline (T0) and after at least three months of therapy (T1), and blood glucose and lipid profiles at T0. Here, we show significant increases in several anthropometric parameters in both groups, a negative correlation between HDL and ΔWC in the risperidone group and positive correlations between insulin and ΔBMI and between HOMA-IR and ΔBMI in the sertraline group. Despite the sample size, these results are important because it is difficult to study adolescents who are long-term-compliant with psychotropic drugs. This pilot study supports the importance of future large-scale investigations to understand the metabolic risk profiles of psychotropic drugs, their individual vulnerabilities and their underlying mechanisms. Simultaneous guideline-based psychiatric and metabolic interventions should be part of daily practice.

The Use of Second-Generation Antipsychotics in Patients with Severe Schizophrenia in the Real World: The Role of the Route of Administration and Dosage-A 5-Year Follow-Up

To assess the impact of the route of administration and doses of second-generation antipsychotics (SGAs) on treatment adherence, hospital admissions, and suicidal behaviour in patients with severe schizophrenia (Clinical Global Impression−Severity−CGI-S ≥ 5), we implemented an observational 5-year follow-up study. A total of 37.5% of the patients on oral antipsychotics (Aps) and 11.5% of those on long-acting injectables (LAIs) abandoned the treatment (p < 0.001). There were no differences in treatment discontinuation between the LAI-AP standard and high-dose groups. A total of 28.1% of the patients on oral Aps had at least one hospitalisation, as well as 13.1% of patients on LAIs (p < 0.001). There were fewer hospitalisations of patients on LAIs in the high-dose group (p < 0.05). Suicide attempts were recorded for 18% of patients on oral Aps but only for 4.6% of patients on LAIs (p < 0.001). No differences were found between the dosage groups on LAIs. Tolerability was good for all Aps and somewhat better for LAIs than oral Aps in terms of side effects (p < 0.05). There were no differences between the standard and high-dose groups. More patients discontinued treatment due to side effects in the oral AP group (p < 0.01). LAI SGA treatment was more effective than oral AP in terms of adherence and treatment outcomes for managing people with severe schizophrenia. Moreover, significant improvements were found that favour high-dose LAI SGA treatment for some of these patients. This study highlights the need to consider LAI antipsychotics and high-dose strategies for patients with severe schizophrenia.

Pharmacogenetics and Schizophrenia-Can Genomics Improve the Treatment with Second-Generation Antipsychotics?

Schizophrenia (SCZ) is a complex psychiatric disorder of multifactorial origin, in which both genetic and environmental factors have an impact on its onset, course, and outcome. Large variability in response and tolerability of medication among individuals makes it difficult to predict the efficacy of a chosen therapeutic method and create universal and precise guidelines for treatment. Pharmacogenetic research allows for the identification of genetic polymorphisms associated with response to a chosen antipsychotic, thus allowing for a more effective and personal approach to treatment. This review focuses on three frequently prescribed second-generation antipsychotics (SGAs), risperidone, olanzapine, and aripiprazole, and aims to analyze the current state and future perspectives in research dedicated to identifying genetic factors associated with antipsychotic response. Multiple alleles of genes involved in pharmacokinetics (particularly isoenzymes of cytochrome P450), as well as variants of genes involved in dopamine, serotonin, and glutamate neurotransmission, have already been identified as ones of significant impact on antipsychotic response. It must, however, be noted that although currently obtained results are promising, trials with bigger study groups and unified protocols are crucial for standardizing methods and determining objective antipsychotic response status.

Comparing the efficacy of aripiprazole as an add-on to valproate with other second-generation antipsychotics in acute mania symptoms in manic patients in Iran

BACKGROUND

Given the great importance of treating patients with bipolar disorder, the aim of this study was to compare the efficacy of aripiprazole with other second-generation antipsychotics in relieving acute symptoms of mania.

MATERIALS AND METHODS

In this study, 50 patients with bipolar I disorder, manic episode, were divided into two groups receiving aripiprazole (n = 25) and other second-generation antipsychotics (risperidone, olanzapine, and quetiapine) (n = 25) for 6 weeks. The disease severity was evaluated and compared according to YMRS and CGI criteria.

RESULTS

The mean severity of mania according to YMRS and CGI, at week 0 in comparison with weeks 2, 4 and 6 in both groups was significantly different (p < 0.0001) and the treatment with Aripiprazole at week 2 (p < 0.0001) and 4 (p = 0.0002) was significantly better than the other second-generation antipsychotics. The two groups also showed an overall improvement in CGI-based results at weeks 4 and 6 (p = 0.002). In addition, the efficacy index for aripiprazole at weeks 4 (p = 0.011) and 6 (p < 0.0001) as well as disease improvement in the second (p < 0.0001) and fourth (p = 0.026) weeks after treatment were better than the other second-generation antipsychotics.

CONCLUSIONS

Aripiprazole and other second-generation antipsychotics, 2 weeks after initiation of treatment, significantly reduced mania severity in patients with bipolar disorder, however, aripiprazole seems to be more efficient and faster for controlling mania in patients with bipolar disorder.KEY POINTSAripiprazole and other second-generation antipsychotics, 2 weeks after initiation of treatment, significantly reduced mania severity in patients with bipolar disorder.Comparison between the two drugs, aripiprazole showed a more beneficial role in the second and fourth weeks than second-generation antipsychotics.Due to the fact that the possible mechanisms involved in the role of aripiprazole have not been considered compared to other antipsychotics in patients with bipolar disorder, there is a need for more extensive studies in this field.

The relation between second-generation antipsychotics and laxative use in elderly patients with schizophrenia

BACKGROUND

We aimed to investigate factors associated with concomitant laxative use among elderly patients with schizophrenia, discharged on second-generation antipsychotics (SGAs), from two large public psychiatric hospitals in Taiwan.

METHODS

Elderly patients with schizophrenia who were discharged between 2006 and 2019 and received SGA monotherapy at discharge were included in the analysis. Multivariate logistic regression was used to identify factors associated with regular laxative use at discharge. The Cochrane-Armitage trend test was used to evaluate whether significant time trends existed for rates of laxative use at discharge.

RESULTS

A total of 2591 elderly patients with schizophrenia were discharged during the study period, and 1727 of 2591 patients who met the inclusion criteria were included for analysis. Of these 1727 patients, 732 (42.4%) also received concomitant laxatives. Female gender, mood stabiliser use and concomitant diabetes mellitus were found to be associated with increased laxative use. Among SGAs, clozapine was associated with the highest rate of laxative use, followed by zotepine, quetiapine, olanzapine and risperidone. Additionally, risperidone, amisulpride, aripiprazole, paliperidone and sulpiride were associated with comparable rates of laxative use. Laxative use rates grew over time from 30.8% in 2006 to 46.6% in 2019 (z = 4.83, P < 0.001).

CONCLUSIONS

Laxative use is common in elderly schizophrenia patients treated with SGAs. In cases of clinically significant constipation, switching to an SGA with a lower risk for constipation, or discontinuing the use of mood stabilisers should be considered, if clinically feasible.

Abuse and misuse of second-generation antipsychotics: an analysis using VigiBaseTM , the World Health Organisation pharmacovigilance database

The study aim was to assess the abuse/misuse potential of second-generation antipsychotics (SGAPs) using VigiBase^TM data. We extracted individual case safety reports (ICSRs) of 'Drug abuse, dependence, and withdrawal' involving SGAPs up to June 2018. We assessed disproportionate reporting by calculating the Information Component (IC), considering the lower end of the 95% credibility interval for IC (IC₀₂₅ ), and the Proportional Reporting Ratio (PRR). We identified 1,683 ICSRs recorded as 'abuse, dependence, and withdrawal' involving SGAPs, mainly quetiapine (n=1,089) and olanzapine (n=209). The disproportional reporting indicators highlighted an association between 'Drug abuse and dependence', and quetiapine, olanzapine, and ziprasidone, as indicated by the IC₀₂₅ (2.263, 0.259, and 1.051, respectively) and PRR values (3.929, 1.020, and 1.334, respectively). The abuse/misuse potential is confirmed for quetiapine and olanzapine and highlighted for the first time for ziprasidone. Physicians should consider these risks when prescribing these antipsychotics, especially to patients with history of drug abuse.

The effect of first- and second-generation antipsychotics on brain morphology in schizophrenia: A systematic review of longitudinal magnetic resonance studies with a randomized allocation to treatment arms

Schizophrenia manifests as loss of brain volume in specific areas in a progressive nature and an important question concerns whether long-term treatment with medications contributes to this. The aim of the current PRISMA systematic review was to search for prospective studies involving randomization to treatment. PROSPERO ID: CRD42020197874. The MEDLINE/PUBMED was searched and it returned 2638 articles; 3 were fulfilling the inclusion criteria. A fourth was published later; they included 359 subjects, of whom 86 were healthy controls, while the rest were first-episode patients, with 91 under olanzapine, 93 under haloperidol, 48 under risperidone, 5 under paliperidone, 6 under ziprasidone, and 30 under placebo. Probably one-third of patients were suffering from a psychotic disorder other than schizophrenia. The consideration of their results suggested that there is no significant difference between these medications concerning their effects on brain structure and also in comparison to healthy subjects. There does not seem to be any strong support to the opinion that medications that treat psychosis cause loss of brain volume in patients with schizophrenia. On the contrary, the data might imply the possible presence of a protective effect for D2, 5-HT2, and NE alpha-2 antagonists (previously called SGAs). However, the literature is limited and focused research in large study samples is essential to clarify the issue, since important numerical differences do exist. The possibility of the results and their heterogeneity to be artifacts secondary to a modification of magnetic resonance imaging (MRI) signal by antipsychotics should not be easily rejected until relevant data are available.

The FTO rs9939609 Variant Is Associated with Cardiometabolic Disease Risk and Dietary Energy Intakes in Children with Mental Health Disorders

Background

Second-generation antipsychotics (SGAs) are used to treat children for mental health disorders but in some children they cause cardiometabolic complications including weight gain and type 2 diabetes. Genetic variants can place a child at risk of developing these metabolic complications. The fat mass and obesity-associated (FTO) rs9939609 A allele has been associated with obesity and dietary energy intakes in healthy children but its relation to metabolic complications in SGA-treated children is not known.

Objectives

This study investigated the association of the FTO rs9939609 variant and SGA treatment with cardiometabolic complications and dietary intakes in children with mental health disorders.

Methods

A cross-sectional population of children (≤18 y; n = 506) with mental health disorders that were SGA-treated (n = 197) and SGA-naïve (n = 309) were recruited through the Department of Psychiatry at BC Children's Hospital. Dietary intakes were estimated using 3-d food records in a subset of children (n = 73).

Results

Genotype frequencies were not different between SGA-treated (TT genotype 42.6%, TA genotype 38.6%, AA genotype 18.8%) and SGA-naïve (TT 41.1%, TA 39.5%, AA 19.4%) children. Children with the A allele had lower BMI z-sores compared with the TT genotype (0.84 ± 1.19 compared with 1.19 ± 1.36; P = 0.005, adjusted for ethnicity). We observed an interaction between FTO genotype and SGA status on fasting glucose (P = 0.036). SGA-naïve children with the A allele had higher fasting glucose than those with the TT genotype (4.96 ± 0.35 compared with 4.81 ± 0.35 mmol/L; P = 0.001), in adjusted models (age, sex, ethnicity, and BMI z-score). This was not observed in SGA-treated children. Children with the A allele had higher daily total energy intakes compared with the TT genotype (1994 ± 619 compared with 1814 ± 484 kcal/d; P = 0.048), in adjusted models (age, sex, ethnicity, and BMI z-score); no effect of SGA-treatment was observed.

Conclusions

Our findings suggest the A allele of the FTO rs9939609 variant is associated with higher BMI in children with mental health disorders, but only in those not treated with SGAs.

Association of Lithium and Second-Generation Antipsychotics with Neurocognition in Youth with Bipolar Disorder

Objective: Numerous studies have examined the association of antimanic medications with neurocognition in adults with bipolar disorder (BD). However, few studies have examined this topic in youth. Thus, we aimed to examine the association of lithium and second-generation antipsychotics (SGAs), the first-line antimanic medications for youth with BD, with neurocognition in a relatively large sample of youth with BD. Methods: Participants included 91 youth with BD-I, -II, or -Not Otherwise Specified, aged 13-20 years (n = 14 current lithium use, n = 51 current SGA use). We examined four tests from the Cambridge Neuropsychological Test Automated Battery: Intra/Extra Dimensional Set-Shifting Task (IED), Rapid Visual Information Processing Task (RVP), Stockings of Cambridge Test (SOC), and Affective Go/No-Go (AGN). Within-sample Z-scores were computed, and a global neurocognitive composite score and g factor derived from these tests comprised the primary outcomes. Multivariable analyses controlled for age, sex, and IQ. Results: Current lithium use was significantly associated with poorer cognitive flexibility/set-shifting (IED). After further controlling for lifetime comorbid attention-deficit/hyperactivity disorder and current depression symptoms in sensitivity analyses, the lithium finding was no longer significant. Current SGA use was significantly associated with greater affective processing bias (AGN). No significant findings survived correction for multiple comparisons. All other cognitive outcomes were not significantly associated with current lithium use, current SGA use, or total number of current medications. Conclusions: Treatment with lithium or SGAs was associated with minimal neurocognitive impairments, with small effect sizes in primary multivariable analyses. This study adds to the limited body of literature examining medication use in relation to neurocognition in youth with BD. While the current study cannot rule out associations of smaller effect size, present findings suggest that leading mood-stabilizing medications are not associated with frank neurocognitive impairments in youth with BD.

The Predictive Role of Aberrant Metabolic Parameters and Negative Automatic Thinking on the Cognitive Impairments Among Schizophrenia Patients with Metabolic Syndrome

PURPOSE

The study aimed to clarify the cognitive impairments of schizophrenia with metabolic syndrome while evaluating their potential as risk factors.

PATIENTS AND METHODS

We recruited 153 participants and divided them into three groups according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, criteria and the guideline standards for the prevention and treatment of dyslipidemia in Chinese adults in 2007 for metabolic syndrome, as follows: healthy control group (n = 47); nonmetabolic syndrome group (n = 58); and metabolic syndrome group (n = 48). Psychotic symptoms were evaluated using the Positive and Negative Syndrome Scale. Cognitive function and automatic thinking were estimated using the Montreal Cognitive Assessment Scale, Verbal Fluency Test, and Automatic Thoughts Questionnaire. Serum biochemical parameters were measured by automatic biochemistry analyzer.

RESULTS

One-way ANOVA analysis revealed that differential cognition impairments in schizophrenia patients compared to controls. Furthermore, results of multiple comparisons showed that more serious barriers in orientation, language fluency, and negative automatic thinking existed in the metabolic syndrome group than in the healthy and non-metabolic syndrome groups. Spearman correlation and stepwise linear regression analyses showed that psychopathological symptoms, high waist circumference, and high triglyceride were the predictive factors for negative automatic thoughts, orientation, and language fluency. Those results collectively revealed that high waist circumference, high triglyceride and negative automatic thinking had validity and effectiveness in predicting the cognitive function impairments of the metabolic syndrome group.

CONCLUSION

The present findings strongly supported the notion that aberrant parameters of high waist circumference, high triglyceride and high negative automatic thoughts had validity and effectiveness predictive role for cognitive impairments in the schizophrenics with metabolic syndrome. The schizophrenia patients with metabolic syndrome should receive regular monitoring and adequate treatment for metabolic and psychological risk factors.

Aripiprazole-induced obsessive-compulsive symptoms

Aripiprazole is a novel antipsychotic with a unique pharmacological profile as a dopamine partial agonist. It is indicated for treatment of schizophrenia and bipolar disorder. This new antipsychotic has low rate of extrapyramidal side effects, metabolic changes and no significant adverse effect on serum prolactin concentration. In addition,it is not associated with significant weight gain like other atypical antipsychotics. As a reason, when other antipsychotics cause these adverse events, it's not uncommon to switch to Aripiprazole. Obsessive compulsive symptoms have been untoward sequel of a few second-generation antipsychotics. Among the second generation antipsychotics Clozapine, Olanzapine, and Risperidone are the most prominent agents associated with these sequelae, according to case reports. More recently, a handful of case reports indicated development of Obsessive-compulsive symptoms with Aripiprazole. We report a case that exhibited similar unexpected adverse effects after administration of Aripiprazole. Keywords: Aripiprazole, Second generation antipsychotics, Obsessive-compulsive symptoms (OCS).

Time to rehospitalization in involuntarily hospitalized individuals suffering from schizophrenia discharged on long-acting injectable antipsychotics or oral antipsychotics

BACKGROUND

Involuntarily hospitalized individuals suffering from schizophrenia often have a poorer prognosis after discharge.

OBJECTIVE

This study aimed to analyze time to rehospitalization within 6 months of discharge in involuntarily hospitalized individuals suffering from schizophrenia discharged on long-acting injectable antipsychotics (LAIs) or oral antipsychotics (OAPs). In addition, temporal trends in LAI use at discharge were explored.

METHODS

Involuntarily hospitalized individuals suffering from schizophrenia discharged from the study hospital between 2006 and 2019 (n = 806) were included in the analysis. Survival analysis was used to compare time to rehospitalization within 6 months of discharge between individuals discharged on LAIs and OAPs, and between first-generation antipsychotic (FGA) LAIs and second-generation antipsychotic (SGA) LAIs. The Cochran-Armitage trend test was used to test whether a temporal trend existed for LAIs use at discharge during the study period.

RESULTS

The LAIs group (n = 231) had a significantly lower rate of rehospitalization and a significantly longer time to rehospitalization than the OAPs group (n = 575). Rehospitalization rate and time to rehospitalization were not significantly different between individuals discharged on FGA-LAIs and SGA-LAIs. LAIs use at discharge grew significantly from 16.77% in 2006 to 50.00% in 2019 (Z = 6.81, p < 0.0001). Among all LAIs, only use of SGA-LAIs at discharge increased significantly (Z = 5.74, p < 0.0001), but not FGA-LAIs.

CONCLUSIONS

LAIs were superior to OAPs in preventing rehospitalization. However, SGA-LAIs were comparable with FGA-LAIs in reducing rehospitalization risk. Use of LAIs increased significantly in discharged involuntarily hospitalized individuals during the study period, especially SGA-LAIs.

Managing acute agitation and aggression in the world of drug shortages

Acute agitation and aggression create safety risks for both patients and staff, often leading to psychiatric emergencies. Quick and appropriate treatment is necessary to achieve safe and effective outcomes. Unfortunately, there are several factors that hinder timely interventions, such as medication shortages and delay in staff preparedness. Ultimately, the goal of managing acute agitation and aggression in the clinical setting is to de-escalate the situation and prevent harm to patients and staff. This article will explore useful interventions in realizing treatment goals for the management of agitation and aggression in adults while navigating limitations faced in practice.

The Relationship between the Second-Generation Antipsychotics Efficacy and the Traditional Chinese Medicine Body Constitutions in Patients with Schizophrenia

Background: Schizophrenia requires lifelong treatment; Second-generation Antipsychotics (SGAs) have become the most prescribed medication for schizophrenia patients. The efficacy of various SGAs treatment may differ in schizophrenia patients with various traditional Chinese medicine (TCM) body constitution (BC) types. Method: This study applied a longitudinal quantitative research design, where a total of 66 participants were recruited. The Positive and Negative Symptom Scale (PANSS) and the Clinical Global Impression (CGI) score were used to evaluate patients’ psychopathology status in hospitalization, and body constitution questionnaires were conducted by face-to-face interviews in the 1st, 3rd, and 6th week of hospitalization. Results: More than 60% of schizophrenia patients who were treated with SGAs were classified to have unbalanced BC types including Yin-Xu, Yang-Xu and Stasis. Generalized estimating equation analysis revealed significant time effects in CGI and PANSS score improvements in both unbalanced and gentleness (balance) BC types, but no significant changes in the group and group-time interaction in the CGI and PANSS scores in different BC type groups. Conclusions: Schizophrenia patients under SGAs treatment had a higher proportion of unbalanced BC types which may lead to poorer physical or mental statuses, such as overweight problems. Health care providers could apply interventions according to patients’ BC types for disease prevention.

The Choice of Either Quetiapine or Aripiprazole as Augmentation Treatment in a European Naturalistic Sample of Patients With Major Depressive Disorder

BACKGROUND

Augmentation with second-generation antipsychotics (SGAs) represents an evidence-based psychopharmacotherapeutic strategy recommended in case of insufficient response to the first-line antidepressant (AD) treatment in major depressive disorder (MDD). Comparative evidence regarding efficacy and prescription preferences of the individual SGAs is scarce.

METHODS

In the scope of this European, multi-site, naturalistic cross-sectional investigation with retrospective assessment of treatment outcome, we compared sociodemographic and clinical characteristics of 187 MDD patients receiving either quetiapine (n = 150) or aripiprazole (n = 37) as augmentation of their first-line AD psychopharmacotherapy.

RESULTS

Comorbid posttraumatic stress disorder and diabetes were significantly associated with aripiprazole augmentation in our primary and post-hoc binary logistic regression analyses. Furthermore, we identified an association between aripiprazole co-administration and the presence of additional psychotic features, higher rates of AD combination treatment, and a longer duration of psychiatric hospitalizations during the lifetime, which, however, lost significance after correcting for multiple comparisons. Regarding treatment outcome, we found a trend of higher response rates and greater reductions in severity of depressive symptoms in MDD patients dispensed quetiapine.

CONCLUSIONS

Factors associated with a more chronic and severe profile of MDD seem to encourage clinicians to choose aripiprazole over quetiapine, that was, however, administered in the majority of our MDD patients, which might reflect the current approval situation allowing to prescribe exclusively quetiapine as on-label augmentation in MDD in Europe. Given the retrospective assessment of treatment response, the markedly smaller proportion of patients receiving aripiprazole augmentation generally showing an unfavorable disease profile, and the partially heterogeneous statistical robustness of our findings, further studies are required to elaborate on our observation and to generate unambiguous recommendations regarding the choice of first-line SGA augmentation in MDD.

Long-acting second-generation and oral antipsychotics for substance use disorders and psychotic symptoms: Prescribing attitudes among Italian psychiatrists

PURPOSE

To explore Italian psychiatrists' attitudes toward the off-label use of second generation antipsychotics (SGAs) in patients with substance use disorder and psychotic symptoms.

DESIGN AND METHODS

A sample of 300 Italian psychiatrists associated with the Italian Society of Neuropsychopharmacology was randomly selected to complete a survey about the off-label prescription of SGAs.

FINDINGS

Oral aripiprazole (32.7%), olanzapine (30.2%), and quetiapine (25.2%) were considered "appropriate." Long-acting antipsychoticss were generally considered "inappropriate."

PRACTICE IMPLICATIONS

Our findings reflect a substantial level of uncertainty and a lack of coherent clinical guidance within the realm of dual diagnosis treatment. Therefore, they emphasize the need to develop specific guidelines to improve the management of pharmacotherapy among this population.

Second-Generation Antipsychotics in Management of Acute Pediatric Bipolar Depression: A Systematic Review and Meta-analysis

Objectives: To evaluate the efficacy in reduction of depressive symptoms, and safety and tolerability of second-generation antipsychotics (SGAs) to manage pediatric bipolar depression (PBD). Methods: We conducted a systematic review for randomized clinical trials (RCTs) for PBD in MEDLINE, Scopus, and EMBASE. Four (quetiapine: 2, lurasidone: 1, olanzapine-fluoxetine combination [OFC]: 1) out of 569 studies met the criteria for inclusion in meta-analysis. RevMan was used for statistical analysis, and the mean difference (MD) between mean children's depression rating scale-revised (CDRS-R) score was used to measure treatment difference between SGA and placebo. Results: Lurasidone displayed a significant reduction in depressive symptoms (MD -5.70, 95% confidence interval [CI] -8.67 to -2.73) in PBD, followed by OFC (MD -5.00, 95% CI -8.64 to -1.36) and quetiapine (MD -2.30, 95% CI -6.80 to 2.20; MD 1.00, 95% CI -9.88 to 11.88). The response was significantly higher for lurasidone (59.5% vs. 36.5%; p < 0.001) and OFC (78.2% vs. 59.2%, p = 0.003) compared with placebo. There was no statistically significant MD in treatment and response rates between quetiapine and placebo in all RCTs. The weighted mean CDRS-R total score difference was -4.58 (95% CI -6.59 to -2.56) and overall effect was significant (p < 0.00001). Importantly, the p value for heterogeneity was 0.46, which indicated that there was no heterogeneity between outcomes of the studies. The number needed to treat (NNT) for lurasidone was 4.3, followed by OFC (NNT = 5.3) and quetiapine (NNT = 12.5; NNT = 25). Conclusion: Our findings showed lurasidone and OFC were more efficacious than placebo for acute depressive episodes in PBD. RCTs of treatments for PBD remain scarce pressing the need for more research.

Metabolomic connections between schizophrenia, antipsychotic drugs and metabolic syndrome: A variety of players

BACKGROUND

Diagnosis of schizophrenia lacks of reliable medical diagnostic tests and robust biomarkers applied to clinical practice. Schizophrenic patients undergoing treatment with antipsychotics suffer a reduced life expectancy due to metabolic disarrangements that co-exist with their mental illness and predispose them to develop metabolic syndrome, also exacerbated by medication. Metabolomics is an emerging and potent technology able to accelerate this biomedical research. <P> Aim: This review focus on a detailed vision of the molecular mechanisms involved both in schizophrenia and antipsychotic-induced metabolic syndrome, based on innovative metabolites that consistently change in nascent metabolic syndrome, drug-naïve, first episode psychosis and/or schizophrenic patients compared to healthy subjects. <P> Main lines: Supported by metabolomic approaches, although not exclusively, noteworthy variations are reported mainly through serum samples of patients and controls in several scenes: 1) alterations in fatty acids, inflammatory response indicators, amino acids and biogenic amines, biometals and gut microbiota metabolites (schizophrenia); 2) alterations in metabolites involved in carbohydrate and gut microbiota metabolism, inflammation and oxidative stress (metabolic syndrome), some of them shared with the schizophrenia scene; 3) alterations of cytokines secreted by adipose tissue, phosphatidylcholines, acylcarnitines, Sirtuin 1, orexin-A and changes in microbiota composition (antipsychotic-induced metabolic syndrome). <P> Conclusion: Novel insights into the pathogenesis of schizophrenia and metabolic side-effects associated to its antipsychotic treatment, represent an urgent request for scientifics and clinicians. Leptin, carnitines, adiponectin, insulin or interleukin-6 represent some examples of candidate biomarkers. Cutting-edge technologies like metabolomics have the power of strengthen research for achieving preventive, diagnostic and therapeutical solutions for schizophrenia.

Greater Arterial Stiffness in Children with or without Second-generation Antipsychotic Treatment for Mental Health Disorders: Rigidité Artérielle Plus Importante Chez Les Enfants Avec ou Sans Traitement Par Antipsychotiques de la Deuxième Génération Pour des Troubles de Santé Mentale

OBJECTIVE

Second-generation antipsychotics (SGAs) are used for a variety of mental disorders and are associated with cardiometabolic side effects in children. The objective of this study was to assess the cardiovascular health of children with mental disorders that are SGA-treated or SGA-naive.

METHODS

SGA-treated (n = 47) or SGA-naive (n = 37) children (aged 6 to 18 years) with mental disorders and control children (n = 83, no mental disorder) underwent assessment for cardiac function and morphology by echocardiography, aortic pulse wave velocity (PWV), and carotid intima-media thickness (cIMT). Body mass index (BMI) z-scores, waist circumference z-scores, systolic and diastolic blood pressure (BP) percentiles for height and sex, and fasting plasma glucose, insulin, triglycerides, and cholesterol were also assessed. Differences between SGA-treated, SGA-naive, and control children were assessed by linear and log-linear regression models.

RESULTS

SGA-treated children had greater BMI z-scores and overweight/obesity (BMI ≥ 85th percentile for age and sex) and hypertension than SGA-naive and control children. The PWV geometric mean was 11.1% higher in SGA-treated (95%CI, 3.95 to 18.77) and 12.9% higher in SGA-naive children (95% CI, 5.60 to 20.59) compared to controls in models adjusted for age, sex, BMI, and systolic BP percentile. Left ventricular (LV) end-diastolic dimension/body surface area (BSA), LV end-systolic dimension/BSA, and LV ejection fraction were lower in SGA-treated and SGA-naive children compared to controls in models adjusted for sex and age.

CONCLUSIONS

Children with mental disorders have greater arterial stiffness and altered cardiac structure/function than children with no mental health diagnosis. SGA treatment in children is not associated with alterations in cardiovascular structure/function.

Long-Term Metabolic Monitoring of Youths Treated with Second-Generation Antipsychotics 5 Years after Publication of the CAMESA Guidelines Are We Making Progress? Surveillance Métabolique à Long Terme des Jeunes Traités par Antipsychotiques de Deuxième Génération, Cinq ans Après la publication des Lignes Directrices Camesa: Faisons-Nous des Progrès?

OBJECTIVE

The potential metabolic adverse effects of second-generation antipsychotics (SGA) need to be monitored. The Canadian Alliance for Monitoring Effectiveness and Safety of Antipsychotics (CAMESA) offers guidelines for this purpose. We aimed to evaluate the long-term rates of youths receiving monitoring in mental health clinics and document the factors that may influence them.

METHOD

The charts of 180 patients (13.3 ± 3.1 years, 54.4% males) receiving SGA treatment for the first time between January 2016 and June 2018 were reviewed. Monitoring was divided into baseline and 1- to 6-month and 9- to 24-month periods. Population under study was stratified into children (4 to 12 years) and adolescents (13 to 18 years). Sociodemographic characteristics, psychiatric diagnosis and comorbidities, prescribed SGAs and comedications, anthropometric measures (AM), blood pressure (BP), blood tests (BT), electrocardiogram, and the psychiatrist's years of practice were collected. Cross tables were used to present the monitoring rates. Categories were compared by covariate analysis. Rates of patients monitored across categories were compared using Fisher exact test.

RESULTS

Monitoring rates for AM, BT, and BP were 55%, 47.8%, and 46.7% at baseline; 50%, 41.7%, and 45.2% at 1 to 6 months; and 47.2%, 41.5%, and 40.6% at 9 to 24 months, respectively. Higher monitoring rates were significantly associated with adolescent status (baseline, 1 to 6 months), a diagnosis of psychotic and/or affective disorder (baseline, 1 to 6 months, 9 to 24 months), having ≤1 psychiatric comorbidities (1 to 6 months), high SGA dose (baseline, 1 to 6 months), and clinician's experience (baseline, 9 to 24 months). Significantly lower monitoring rates were associated with the psychostimulant/atomoxetine comedication (baseline, 1 to 6 months, 9 to 24 months).

CONCLUSION

Five years after publication of the CAMESA guidelines, metabolic monitoring is conducted for less than half of patients. In our sample, age, diagnostic category, psychiatric comorbidities, SGA dose, clinician's experience, and comedications influenced the monitoring rates. Major progress still needs to be made before reaching a satisfactory level of monitoring.

Monitoring for the metabolic side effects of second-generation antipsychotic medications: Psychiatrists' views and practices

PURPOSE

The aims of this study were to explore (1) the knowledge, attitudes, practices, and adherence of psychiatrists in Jordan regarding published guidelines for metabolic monitoring of patients taking second-generation antipsychotics (SGAs), and (2) their perceived barriers to metabolic screening.

METHODS

The study utilized a cross-sectional survey. Data were collected from 91 psychiatrists using a self-administered questionnaire.

FINDINGS

Almost 74% of psychiatrists reported they were aware of metabolic screening guidelines for patients taking SGA. However, the results of their assessment practices revealed a lack of adherence to these guidelines. Reported barriers to metabolic screening were the financial burden on the family and lack of family and patient compliance with recommendations of monitoring.

PRACTICE IMPLICATIONS

Metabolic side effects of SGAs are important in Arab countries, where baseline levels of obesity and metabolic syndrome are already high in the general population. By virtue of their close proximity to patients, nurses are ideally placed to monitor how patients perceive SGAs and to provide information, advice, and counseling support.

Profile of recipients of holistic health counselling in a psychiatric OPD in South India

BACKGROUND OF THE STUDY

Persons with mental illness (PwMI) are prone to weight gain as a side effect of antipsychotics. Health counselling on diet, physical activity, medication adherence, expressed emotions and technology use, by health professionals, can help in managing these side-effects.

AIM

The aim of this study was to identify the pre-counselling profile of the subjects such as body mass index (BMI), diet, physical activity, medication adherence, expressed emotions and technology use among PwMI; to attend the Holistic Health Clinic as part of follow-up services in the psychiatry Outpatient Department (OPD) as well as to find correlation and association between the study variables.

METHODS

The study involved a cross-sectional descriptive design based on convenience sampling. The sample consists of 56 patients who are receiving antipsychotics under symptom control (self-reported) and were overweight. Data were collected with a patient assessment proforma and analysed using SPSS-22.

RESULTS

The patients referred to the holistic health counselling (HHC) had abnormal weight and BMI. The mean and SD of weight was 74.48 ± 14.07 and BMI 29.51 ± 5.15. All the participants received counselling on diet, 87.5% on physical activity, 62.5% on sleep hygiene, 55.4% on medication adherence, 8.9% on family emotional climate and only 5.4% on healthy use of technology. Weight has shown significant relation with gender (male = 80.84 ± 17.71, female = 71.09 ± 10.52, t = -2.52, p = .015) and near to significant relationship (χ² = 7.685, p = .053) with educational status.

CONCLUSION

Patients receiving second-generation antipsychotics (SGA) have lesser extra pyramidal side-effects; however, they are more prone to gain weight. Proper screening and counselling during the follow-up visit in the outpatient setting can help in identification, prevention and management of the obesity-related metabolic syndrome and cardiovascular disease (CVD), and motivate them to adopt healthy behaviours.

Male-Specific Metabolic Considerations Concerning the Prescription of Second-Generation Antipsychotics to Adolescents

Objectives: Although males and females gain comparable weight when prescribed second-generation antipsychotics (SGAs), males may be uniquely vulnerable to an array of endocrinological, inflammatory, and psychosocial adverse drug effects. Methods: This opinion piece reviews work in each of these three areas for consideration. Results: Androgens may decrease both through hypothalamic-pituitary-gonadal axis dysregulation and as a consequence of increased adiposity. Testosterone has anti-inflammatory properties, and declining levels as well as many other factors may influence overall immunological functioning. Psychosocial stressors are gender specific in obesity, and SGA-induced obesity may affect males in unique and severe ways. Conclusion: This opinion piece supports the framework of the World Federation of Societies of Biological Psychiatry's Task Force on Men's Mental Health to advocate for further studies concerning the adverse drug effects of SGAs as unique manifested in male children, adolescents, and young men.

Cariprazine as a therapeutic option for schizophrenia: a drug evaluation

Introduction: Schizophrenia is a very disabling condition that may result in a significant impairment of individual, professional, and social adjustments. Antipsychotics (APs), the first-line treatment for schizophrenia, in many cases modify the course of the disease, by reducing the institutionalization risk, at the price of severe and invalidating side effects. Cariprazine is one of the latest second-generation APs (SGAs) acting as a partial agonist of type 2 and 3 dopamine receptors, which was recently approved for the treatment of adult schizophrenia.Areas covered: The authors provide a critical review and commentary on the currently available data on the effectiveness and tolerability of cariprazine in schizophrenic patients, with a particular focus on its specific target symptoms.Expert opinion: Cariprazine appears significantly effective on both acute and maintenance treatment of schizophrenia, and in improving positive, negative, and cognitive symptoms, slightly more than other SGAs. It shows a good safety and tolerability profile, with akathisia being its most common side effect. Although further independent studies are needed to clarify its precise advantages over other SGAs, cariprazine seems a promising compound not only in schizophrenia, but also in a broad range of psychiatric conditions, including perhaps bipolar and addictive disorders.

Long-acting injectable aripiprazole in pregnant women with schizophrenia: a case-series report

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.

Treatment-related weight gain and metabolic complications in children with mental health disorders: potential role for lifestyle interventions

Over 1 million Canadian children are estimated to have a mental health disorder, which are commonly treated with medications, such as second-generation antipsychotics (SGAs). Estimates suggest that SGA prescriptions to children are increasing in Canada. Although these medications are important and lifesaving components of psychiatric treatment, they are not without side effects. For some children, SGA treatment is associated with adverse metabolic complications including rapid weight gain, dyslipidemia, elevated blood pressure, and risk for type 2 diabetes. It is not clear why these complications develop, but it is assumed that SGAs stimulate appetite and food intake, and reduce resting energy expenditure leading to weight gain and that the metabolic complications occur secondary to the weight gain. Understanding the mechanisms underlying these complications is key to being able to identify children at risk and prevent and optimize treatment. In this narrative review, we provide an overview of the literature pertaining to the weight gain and metabolic complications in children treated with SGAs, highlighting the scope of the problem and the current limited research on how diet and physical activity can be used to prevent or lessen the severity of the metabolic complications and improve the long-term health trajectories of SGA-treated children. Novelty: Children are increasingly being treated with second-generation antipsychotics for mental health disorders. Dietary and physical activity assessments are not commonly considered in clinical settings. Randomized controlled trials of lifestyle interventions are needed to determine the effectiveness of mitigating the cardiometabolic complications in second-generation antipsychotic-treated children.

Dopamine, Cognitive Impairments and Second-Generation Antipsychotics: From Mechanistic Advances to More Personalized Treatments

The pharmacological treatment of cognitive impairments associated with schizophrenia is still a major unmet clinical need. Indeed, treatments with available antipsychotics generate highly variable cognitive responses among patients with schizophrenia. This has led to the general assumption that antipsychotics are ineffective on cognitive impairment, although personalized medicine and drug repurposing approaches might scale down this clinical issue. In this scenario, evidence suggests that cognitive improvement exerted by old and new atypical antipsychotics depends on dopaminergic mechanisms. Moreover, the newer antipsychotics brexpiprazole and cariprazine, which might have superior clinical efficacy on cognitive deficits over older antipsychotics, mainly target dopamine receptors. It is thus reasonable to assume that despite more than 50 years of elusive efforts to develop novel non-dopaminergic antipsychotics, dopamine receptors remain the most attractive and promising pharmacological targets in this field. In the present review, we discuss preclinical and clinical findings showing dopaminergic mechanisms as key players in the cognitive improvement induced by both atypical antipsychotics and potential antipsychotics. We also emphasize the concept that these mechanistic advances, which help to understand the heterogeneity of cognitive responses to antipsychotics, may properly guide treatment decisions and address the unmet medical need for the management of cognitive impairment associated with schizophrenia.

The effect of a computerized best practice alert system in an outpatient setting on metabolic monitoring in patients on second-generation antipsychotics

WHAT IS KNOWN AND OBJECTIVE

Metabolic syndrome is a well-documented adverse effect of second-generation antipsychotics (SGAs). Patients with metabolic syndrome are at an increased risk of potentially fatal cardiovascular events, including myocardial infarction and stroke. This elevated risk prompted the creation of a national guideline on metabolic monitoring for patients on SGAs in 2004. However, monitoring practices remained low at our clinic. To address this concern, a clinical decision support system was developed to alert providers of monitoring requirements. The purpose of this study is to determine the effect of the best practice alert (BPA), and to assess the impact of provider and patient characteristics on metabolic laboratory (lab) order rates.

METHODS

A retrospective chart review was conducted at a large outpatient psychiatric clinic. Data were collected from all adult patients who were prescribed an SGA and triggered the BPA (indicating lab monitoring is needed for the patient). Data collection included a variety of patient, provider and alert variables. The primary outcome was a composite of fasting blood glucose (FBG), haemoglobin A1c (HbA1c) and/or fasting lipid panel order rates. Secondary outcomes included the rate of valid response, which considered appropriate reasons for not ordering labs (ie monitoring already completed during recent primary care visit), as well as order rates of individual labs.

RESULTS AND DISCUSSION

Data from 1112 patients were collected and analysed. Patients with a thought disorder diagnosis had significantly more labs ordered than those without. No other patient factors affected order rates. Resident psychiatrists and nurse practitioners ordered significantly more labs and had significantly more valid responses than attending psychiatrists. An active alert, which fired during medication order entry, was associated with a higher rate of lab ordering and valid response compared to a passive alert, which fired whenever a prescribing healthcare provider opened the chart.

WHAT IS NEW AND CONCLUSION

Prescribers may associate metabolic syndrome with schizophrenia or with use of SGAs specifically in thought disorders, even though these medications pose a risk for all indications. Higher rates of monitoring by resident physicians may have been due to spending more time with patients during the encounter and in documentation. Lastly, the active BPA was an effective tool to increase metabolic monitoring in patients taking SGAs. Continued education on the importance of regular metabolic monitoring should be implemented for all providers.

Treatment Response of Add-On Esketamine Nasal Spray in Resistant Major Depression in Relation to Add-On Second-Generation Antipsychotic Treatment

In this meta-analysis, we aimed to estimate and compare the efficacy of add-on treatment of antidepressants with esketamine nasal spray and second-generation antipsychotics in patients with nonpsychotic major depressive disorder and inadequate response to antidepressants. Searching for acute-phase, double-blind, placebo-controlled, randomized trials, we found 22 second-generation antipsychotic (n = 8363) and 3 intranasal esketamine (n = 641) studies. Mean change in the Montgomery Åsberg Depression Rating Scale total score served as outcome. We determined a higher mean difference (vs placebo) for the pooled esketamine nasal spray trials (mean difference = 4.09, 95% confidence interval: 2.01 to 6.17) than for the pooled second-generation antipsychotic augmentation trials (mean difference  = 2.05, 95% confidence interval: 1.51 to 2.59). Thus, the effect size for intranasal esketamine was nearly twice as high as those for the second-generation antipsychotics. This indicates high efficacy of add-on esketamine nasal spray in treatment-resistant major depressive disorder compared with other well-established, evidence-based pharmacological options such as augmentation with second-generation antipsychotics.

New antipsychotic drugs for the treatment of agitation and psychosis in Alzheimer's disease: focus on brexpiprazole and pimavanserin

Behavioral and psychological symptoms of dementia are symptoms of disturbed perception, mood, behavior, and thought content that occurred frequently. These symptoms, which include apathy, depression, anxiety, psychosis, agitation, and aggression, can serve as predictors of and early clinical diagnostic markers for Alzheimer's disease (AD) and are common precipitants of institutional care. Agitation and psychosis are associated with accelerated disease progression and increased tau phosphorylation in patients with AD. Current guidelines recommend the use of second-generation antipsychotics for the treatment of agitation and psychosis in AD, but only after first-line non-pharmacological interventions and for no longer than 12 weeks because long-term use of these drugs is associated with an increased risk of mortality and an increased frequency of cerebrovascular events. Therefore, new antipsychotic drugs with improved efficacy and safety are needed as an alternative to current antipsychotic drugs. In this report, we discuss some of the most relevant advances in the field of agitation and psychosis in AD and focus on the recent positive clinical evidence observed with two new antipsychotics drugs: brexpiprazole and pimavanserin. Brexpiprazole is a receptor partial agonist (D2, D3, 5-HT1A), receptor antagonist (5-HT2A/B, α1B/α2C) according to the neuroscience-based nomenclature. Two recent phase III clinical trials have shown that brexpiprazole 2 mg/day is effective for the treatment of agitation in patients with AD and has an improved tolerability and safety profile compared with currently available second-generation antipsychotics. Pimavanserin is a receptor antagonist (5-HT2A, 5-HT2C) that has been given market authorization for psychosis occurring in Parkinson's disease. Recent phase II studies suggest that this drug is effective in AD patients with more severe psychosis, although further long-term studies are needed to better define the efficacy and long-term safety profile of pimavanserin for the treatment of psychosis in AD.

The Relationships Between Obsessive-Compulsive Disorder and Psychosis: An Unresolved Issue

OBJECTIVE

The aim of the present paper was to review and comment on available literature on the complex relationships between obsessive-compulsive disorder OCD and psychotic disorders, with a focus on diagnostic issues, as well as clinical and prognostic implications.

METHOD

The databases of PubMed, Scopus, Embase, PsycINFO and Google Scholar were accessed in order to research and collect articles published in English language only, according to the PRISMA guidelines. Free text terms and MeSH headings were combined as it follows: " Obsessive-compulsive disorder" OR "Obsessive-Compulsive Symptoms" AND "Schizophrenic Disorders" OR "Schizophrenic Symptoms" AND "Antipsychotic Treatment" OR "Second-Generation Antipsychotics "SGAs".

RESULTS

The relationships between obsessive-compulsive disorder (OCD) and schizophrenia spectrum disorders, intended as diagnostic categories, as well as the overlap between obsessive-compulsive and psychotic symptoms, represent an interesting example of how "neurosis" and "psychosis" actually stand along a longitudinal and transversal continuum, much more frequently than it was supposed in the past. It also poses a challenge for clinicians, since treating some symptoms of one disorder may trigger or worsen the other one.

CONCLUSIONS

The question of the symptom overlapping between OCD and psychoses remains unresolved, if considered within the stringent categorization of the available diagnostic systems, but even all the attempts to explain the heterogeneity of the clinical pictures, according to other theoretical constructs, result inconclusive. The controversial role of antipsychotics, especially of SGAs in the treatment of these complex patients is another problem to be clarified in future and more focused studies.

Current and Novel Approaches to Mitigate Cardiometabolic Adverse Effects of Second-Generation Antipsychotics

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.

Current follow-up practices often fail to detect metabolic and neurological adverse reactions in children treated with second-generation antipsychotics

AIM

This study examined the use and adverse reactions of second-generation antipsychotics (SGAs), alone or combined with other psychotropic medication, to identify areas for standardising prescribing and monitoring practices.

METHODS

We conducted a retrospective study at Tampere University Hospital, Finland, involving 128 patients (81% boys) who were under 13 years old at SGA initiation and had SGA treatment between October 2013 and October 2014.

RESULTS

The median age at baseline was 9.4 years. Weight gain was reported as an adverse reaction in 33%, but an increase in standardised body mass index, adjusted for age and sex (BMI z-score), was detected in 75% of patients with sufficient data. The statistically significant median changes during the study were an increase of 0.46 in BMI z-score, a reduction of 0.25 mmol/L in fasting plasma high-density lipoprotein and an increase of 0.28 mmol/L in triglyceride values. The weight gain was most apparent in patients treated with just an SGA or SGA plus melatonin. Patients treated with an SGA plus medication for attention deficit hyperactivity disorder were less likely to gain weight.

CONCLUSION

SGA-induced metabolic disturbances remained partly unrecognised in children under 13 years of age and more systematic monitoring is needed.

Second-Generation Antipsychotics and Dysregulation of Glucose Metabolism: Beyond Weight Gain

Second-generation antipsychotics (SGAs) are the cornerstone of treatment for schizophrenia because of their high clinical efficacy. However, SGA treatment is associated with severe metabolic alterations and body weight gain, which can increase the risk of type 2 diabetes and cardiovascular disease, and greatly accelerate mortality. Several underlying mechanisms have been proposed for antipsychotic-induced weight gain (AIWG), but some studies suggest that metabolic changes in insulin-sensitive tissues can be triggered before the onset of AIWG. In this review, we give an outlook on current research about the metabolic disturbances provoked by SGAs, with a particular focus on whole-body glucose homeostasis disturbances induced independently of AIWG, lipid dysregulation or adipose tissue disturbances. Specifically, we discuss the mechanistic insights gleamed from cellular and preclinical animal studies that have reported on the impact of SGAs on insulin signaling, endogenous glucose production, glucose uptake and insulin secretion in the liver, skeletal muscle and the endocrine pancreas. Finally, we discuss some of the genetic and epigenetic changes that might explain the different susceptibilities of SGA-treated patients to the metabolic side-effects of antipsychotics.

Efficacy and safety of electroacupuncture on metabolic syndrome due to olanzapine and risperidone: Study protocol for a randomized controlled pilot trial

INTRODUCTION

With the second-generation antipsychotics (SGAs) widely applied to treat patients with schizophrenia, adverse effects, especially the metabolic syndrome (MetS), were paid more attention following by the efficacy of SGAs. Several studies have suggested that acupuncture could be an effective and safe intervention for MetS. Here, we present a study protocol to investigate the effect of electroacupuncture on MetS due to olanzapine and risperidone.

METHODS

This study is a prospective, randomized, single-centered, patient-assessor-blinded, parallel-controlled clinical pilot trial. In all, 36 patients will be randomized to an experimental group or control group by a 1:1 ratio. All patients will receive lifestyle interventions. The experimental group will receive electroacupuncture treatment. The control group will receive sham electroacupuncture treatment. The primary outcomes are body mass index (BMI) and waist circumference (WC). The secondary outcome measures include blood pressure (BP), fasting blood glucose (FBG), triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), leptin, and adiponectin. We will assess at baseline, 8 weeks after intervention and at the end of 3 months' follow-up.

DISCUSSION

The results of this trial are expected to provide data on the efficacy and safety of electroacupuncture on MetS due to olanzapine and risperidone, and potential biochemical mechanism.

Time to Rehospitalization in Patients With Schizophrenia Receiving Long-Acting Injectable Antipsychotics or Oral Antipsychotics

BACKGROUND

This study aimed to investigate and compare time to rehospitalization in patients with schizophrenia receiving long-acting injectable antipsychotics (LAIs) after discharge with those receiving oral antipsychotics. Additionally, the trend of LAIs prescription rates was investigated.

METHODS

Patients with schizophrenia (n = 13 087), who were discharged from the study hospital from 2006 to 2017, were followed-up under naturalistic conditions in the year after discharge. The primary outcome was time to rehospitalization. Survival analysis was used in the comparisons between LAIs and oral antipsychotics and between FGA-LAIs and SGA-LAIs. Simple linear regression and Cochrane-Armitage trend test were used to test whether a time trend existed for LAIs prescription rates.

RESULTS

In the 1 year following discharge, patients in the LAIs group had a significantly lower rehospitalization rate and a significantly lengthened time to rehospitalization than those in the oral antipsychotics group. Rehospitalization rate and time to rehospitalization were not significantly different in patients receiving FGA-LAIs or SGA-LAIs. A significantly higher percentage of patients treated with FGA-LAIs received anticholinergic agents than those treated with SGA-LAIs. The LAIs prescription rate grew significantly from 2006 to 2017 by an average of 0.5% per year.

CONCLUSIONS

LAIs were significantly superior to oral antipsychotics in reducing rehospitalization risk, whereas SGA-LAIs were comparable with FGA-LAIs in reducing rehospitalization risk. However, use of concomitant anticholinergic agents was less frequent in the SGA-LAIs group than in the FGA-LAIs group. Increase in LAIs prescription rate may be due to growing experiences and success among clinicians in treating patients with LAIs.

The Effect of Long-Term Second-Generation Antipsychotics Use on the Metabolic Syndrome Parameters in Jordanian Population

Objectives: The aim of this study was to determine the incidence of metabolic syndrome in patients treated with second-generation antipsychotics (SGAs). Methods: In this retrospective study, we reviewed patients’ electronic medical records (EMRs) of all patients who received one SGA for at least six months, excluding patients who were taking other medications that are associated with significant effect on metabolic syndrome. Relevant clinical information was collected prior to starting the SGA and after six months of continuous use of the same SGA. Results: A total of 91 patients were included in the study. The majority of patients (72%) were diagnosed with schizophrenia. After six months of taking the SGA, 44% of patients experienced elevated systolic pressure, 54.9% had elevated triglyceride, and 31.9% had impaired glucose levels (p value < 0.05). Prior to initiating SGA therapy, 14.3% of patients had metabolic syndrome, while 37.4% had metabolic syndrome after six months of therapy, and it was more prominent in males compared to female patients (p value < 0.05). Conclusion: This study found a strong correlation between SGA use and the appearance of metabolic alterations, such as weight gain, glucose intolerance, and increased triglyceride levels. These findings highlight the importance of assessing metabolic deregulations to minimize SGA associated metabolic abnormalities.
