Abstract
Aim The anticholinergic properties of medications are associated with poorer cognitive performance in schizophrenia. Numerous scales have been developed to assess anticholinergic burden and yet, there is no consensus indicating which anticholinergic burden scale is more relevant for patients with schizophrenia. We aimed to identify valid scales for estimating the risk of iatrogenic cognitive impairment in schizophrenia. Methods We identified 27 scales in a literature review. The responses to neuropsychological tests of 839 individuals with schizophrenia or schizoaffective disorder in the FACE-SZ database were collected between 2010 and 2021. We estimated the association between objective global cognitive performance and the 27 scales, the number of psychotropic drugs, and chlorpromazine and lorazepam equivalents in bivariable regressions in a cross-sectional design. We then adjusted the bivariable models with covariates: the predictors significantly associated with cognitive performance in multiple linear regressions were considered to have good concurrent validity to assess cognitive performance. Results Eight scales, the number of psychotropic drugs, and drug equivalents were significantly associated with cognitive impairment. The number of psychotropic drugs, the most convenient predictor to compute, was associated with worse executive function (Standardized β = -0.12, p = .004) and reasoning (Standardized β = -0.08, p = .037). Conclusion Anticholinergic burden, the number of psychotropic drugs, and drug equivalents were weakly associated with cognition, thus suggesting that cognitive impairment in schizophrenia and schizoaffective disorder is explained by factors other than medication. The number of psychotropic drugs was the most parsimonious method to assess the risk of iatrogenic cognitive impairment.

Predictors of valproic acid steady-state serum levels in adult and pediatric psychiatric inpatients: a comparative analysis. Psychopharmacology (Berl) 2024:10.1007/s00213-024-06603-y. [PMID: 38733528 DOI: 10.1007/s00213-024-06603-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Accepted: 04/30/2024] [Indexed: 05/13/2024]
Abstract
RATIONALE Valproic acid (VPA) is commonly used as a second-line mood stabilizer or augmentative agent in severe mental illnesses. However, population pharmacokinetic studies specific to psychiatric populations are limited, and clinical predictors for the precision application of VPA remain undefined. OBJECTIVES To identify steady-state serum VPA level predictors in pediatric/adolescent and adult psychiatric inpatients. METHODS We analyzed data from 634 patients and 1,068 steady-state therapeutic drug monitoring (TDM) data points recorded from 2015 to 2021. Steady-state VPA levels were obtained after tapering during each hospitalization episode. Electronic patient records were screened for routine clinical parameters and co-medication. Generalized additive mixed models were employed to identify independent predictors. RESULTS Most TDM episodes involved patients with psychotic disorders, including schizophrenia (29.2%) and schizoaffective disorder (17.3%). Polypharmacy was common, with the most frequent combinations being VPA + quetiapine and VPA + promethazine. Age was significantly associated with VPA levels, with pediatric/adolescent patients (< 18 years) demonstrating higher dose-adjusted serum levels of VPA (β = 7.6±2.34, p < 0.001) after accounting for BMI. Women tended to have higher adjusted VPA serum levels than men (β = 5.08±1.62, p < 0.001). The formulation of VPA (Immediate-release vs. extended-release) showed no association with VPA levels. Co-administration of diazepam exhibited a dose-dependent decrease in VPA levels (F = 15.7, p < 0.001), suggesting a potential pharmacokinetic interaction. CONCLUSIONS This study highlights the utility of population-specific pharmacokinetic data for VPA in psychiatric populations. Age, gender, and co-administration of diazepam were identified as predictors of VPA levels. Further research is warranted to establish additional predictors and optimize the precision application of VPA in psychiatric patients.

[PMID: 36134676 PMCID: PMC10482725 DOI: 10.1017/s0033291722002732] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Revised: 08/04/2022] [Accepted: 08/08/2022] [Indexed: 11/05/2022]
Abstract
BACKGROUND Relatively few studies have explored the differential contributions of the accumulative dosage of psychotropic medications on mortality in patients with schizophrenia. METHODS We aimed to explore the effects of the exposure dosage of psychotropic medications on mortality during a follow-up period of 5 years with a national cohort of individuals with schizophrenia in 2010. Causes of death were linked through Taiwan's National Mortality Registry. The mean defined daily dose of antipsychotics, antidepressants, mood stabilizers, and sedative-hypnotics, were calculated and survival analyses were conducted. RESULTS A total of 102 964 individuals (54 151 men, 52.59%) with schizophrenia were included. Compared to patients with no exposure to antipsychotics, those with antipsychotic exposure had better survival outcomes, regardless of antipsychotic dosage. Antidepressant exposure, in low and moderate dosage, was associated with decreased all-cause mortality; exposure to mood stabilizers appeared to be associated with an increase in all-cause mortality. Although 89.7% of the patients had been prescribed sedative-hypnotics, exposure to sedative-hypnotics was associated with dose-related increased mortality risk [hazard ratio (HR) in low dose group: 1.16, 95% confidence interval (CI) 1.07-1.27; HR in moderate dose: 1.32, 95% CI 1.21-1.44; HR in high dose: 1.83, 95% CI 1.67-2.01)]. CONCLUSIONS The results indicate that in the treatment of schizophrenia, antipsychotics and antidepressants are associated with lower mortality when using adequate dosages and mood stabilizers and sedative-hypnotics with higher mortality compared with no use. Furthermore, exposure to sedative-hypnotics is associated with a dose-related increased mortality risk which warrants clinical attention and further study.

Abstract
BACKGROUND Antipsychotic polypharmacy (APP) occurs commonly but it is unclear whether it is associated with an increased risk of adverse drug reactions (ADRs). Electronic health records (EHRs) offer an opportunity to examine APP using real-world data. In this study, we use EHR data to identify periods when patients were prescribed 2 + antipsychotics and compare these with periods of antipsychotic monotherapy. To determine the relationship between APP and subsequent instances of ADRs: QT interval prolongation, hyperprolactinaemia, and increased body weight [body mass index (BMI) ⩾ 25]. METHODS We extracted anonymised EHR data. Patients aged 16 + receiving antipsychotic medication at Camden & Islington NHS Foundation Trust between 1 January 2008 and 31 December 2018 were included. Multilevel mixed-effects logistic regression models were used to elucidate the relationship between APP and the subsequent presence of QT interval prolongation, hyperprolactinaemia, and/or increased BMI following a period of APP within 7, 30, or 180 days respectively. RESULTS We identified 35 409 observations of antipsychotic prescribing among 13 391 patients. Compared with antipsychotic monotherapy, APP was associated with a subsequent increased risk of hyperprolactinaemia (adjusted odds ratio 2.46; 95% CI 1.87-3.24) and of registering a BMI > 25 (adjusted odds ratio 1.75; 95% CI 1.33-2.31) in the period following the APP prescribing. CONCLUSIONS Our observations suggest that APP should be carefully managed with attention to hyperprolactinaemia and obesity.

Benzodiazepines and Mood Stabilizers in Schizophrenia Patients Treated with Oral versus Long-Acting Injectable Antipsychotics-An Observational Study. Brain Sci 2023; 13:brainsci13020173.

Abstract
Schizophrenia is a chronic, invalidating, and polymorphic disease, characterized by relapses and remission periods. The main treatment option in schizophrenia are antipsychotics, administered as an oral or as a long-acting injectable (LAI) formulation. Although international guidelines rarely recommend it, mood stabilizers (MS) and/or benzodiazepines (BZD) are frequently prescribed as adjunctive therapy in schizophrenia patients for various reasons. This is an observational, cross-sectional study including stabilized schizophrenia patients. A total of 315 patients were enrolled. Of these, 77 patients (24.44%) were stabilized on LAIs and 238 (75.56%) patients on oral antipsychotics (OAP). Eighty-four patients (26.66%) had concomitant treatment with MS and 119 patients (37.77%) had concomitant benzodiazepine treatment. No statistical significance was observed in MS or BZD use between LAIs and OAPs. In total, 136 patients (43.17%) were stabilized on antipsychotic monotherapy. Our study shows that the long-term use of benzodiazepines and mood stabilizers remains elevated among stabilized schizophrenia patients, regardless of the antipsychotic formulation (oral or LAI). Patients receiving second-generation LAI antipsychotics (SGA-LAI) seem to be more likely to be stabilized on monotherapy compared to those receiving oral antipsychotics. Further randomized controlled trials are necessary in order to clarify the benefits of the current drug polypharmacy trends.

Vasiliu O. The pharmacogenetics of the new-generation antipsychotics - A scoping review focused on patients with severe psychiatric disorders. Front Psychiatry 2023; 14:1124796.

Abstract
Exploring the possible correlations between gene variations and the clinical effects of the new-generation antipsychotics is considered essential in the framework of personalized medicine. It is expected that pharmacogenetic data will be useful for increasing the treatment efficacy, tolerability, therapeutic adherence, functional recovery, and quality of life in patients with severe psychiatric disorders (SPD). This scoping review investigated the available evidence about the pharmacokinetics, pharmacodynamics, and pharmacogenetics of five new-generation antipsychotics, i.e., cariprazine, brexpiprazole, aripiprazole, lumateperone, and pimavanserin. Based on the analysis of 25 primary and secondary sources and the review of these agents' summaries of product characteristics, aripiprazole benefits from the most relevant data about the impact of gene variability on its pharmacokinetics and pharmacodynamics, with significant consequences on this antipsychotic's efficacy and tolerability. The determination of the CYP2D6 metabolizer status is important when administering aripiprazole, either as monotherapy or associated with other pharmacological agents. Allelic variability in genes encoding dopamine D2, D3, and serotonin, 5HT2A, 5HT2C receptors, COMT, BDNF, and dopamine transporter DAT1 was also associated with different adverse events or variations in the clinical efficacy of aripiprazole. Brexpiprazole also benefits from specific recommendations regarding the CYP2D6 metabolizer status and the risks of associating this antipsychotic with strong/moderate CYP2D6 or CYP3A4 inhibitors. US Food and Drug Administration (FDA) and European Medicines Agency (EMA) recommendations about cariprazine refer to possible pharmacokinetic interactions with strong CYP3A4 inhibitors or inducers. Pharmacogenetic data about cariprazine is sparse, and relevant information regarding gene-drug interactions for lumateperone and pimavanserin is yet lacking. In conclusion, more studies are needed to detect the influence of gene variations on the pharmacokinetics and pharmacodynamics of new-generation antipsychotics. This type of research could increase the ability of clinicians to predict favorable responses to specific antipsychotics and to improve the tolerability of the treatment regimen in patients with SPD.

Abstract
BACKGROUND Evidence is limited for the associations between use of psychotropic medications and overactive, aggressive, disruptive or agitated behavior (OADA)1 in clinical practice. AIMS To investigate the associations between risk of readmission with OADA and use of antipsychotics, antidepressants, mood stabilizers and benzodiazepines in patients with schizophrenia. METHOD A consecutive total cohort diagnosed with schizophrenia (N = 663) after admission to the Haukeland University Hospital psychiatric acute unit in Bergen, Norway, was followed from discharge over a 10-year period. At every following readmission, the level of OADA was assessed using the first item of the Health of the Nation Outcome Scale (HoNOS). Periods of use versus non-use of antipsychotics, antidepressants, mood stabilizers and benzodiazepines were recorded as time-dependent variables in each patient and compared using Cox multiple regression analyses. RESULTS A total of 161 (24.3 %) patients were readmitted with OADA, and the mean (SD) and median times in years to readmission with OADA were 2.8 (2.6) and 2.1, respectively. We found that the risk of readmission with OADA was negatively associated with use of antipsychotics (adjusted hazard ratio (AHR) = 0.33, p < 0.01, CI: 0.24-0.46) and antidepressants (AHR = 0.57, p = 0.03, CI: 0.34-0.95), positively associated with use of benzodiazepines (AHR = 1.95, p < 0.01, CI: 1.31-2.90) and not significantly associated with use of mood stabilizers. CONCLUSIONS Use of antipsychotics and antidepressants is associated with reduced risk of readmission with OADA whereas benzodiazepines are associated with an increased risk of readmission with OADA in patients with schizophrenia.

Abstract
Positive mental health (PMH) and mental illness are distinct, yet interrelated, constructs. However, this relationship has yet to be adequately established. We aimed to evaluate the level of PMH and its relationship with sociodemographic and clinical determinants as well as to explore the relationship between PMH and the positive constructs of recovery, subjective wellbeing (SWB), insight and functioning in patients with psychotic disorder. A multicenter, descriptive, cross-sectional and correlational study with a sample of 347 patients with psychotic disorder was conducted. The following assessment instruments were used: Positive Mental Health Questionnaire, Maryland Assessment of Recovery in Serious Mental Illness scale, Insight Scale, Personal Wellbeing Index-Adult version (PWI-A), Overall Life Satisfaction (OLS) and Global Assessment of Functioning scale. The mean global level of PMH was 116.16 (range of 39–156, SD = 19.39). Significant differences were found in PMH in relation to sociodemographic (sex, civil status and employment situation) and clinical variables (family history of mental disorders, number of prescribed antipsychotics, treatment with anxiolytics, treatment with antidepressants and suicide attempts). PMH was significantly and positively correlated with recovery (r = 0.760), SWB (PWI-A: r = 0.728 and OLS: r = 0.602) and functioning (r = 0.243), and negatively with insight (r = −0.335). These results can lead to a major change in mental health care. If actions are taken to increase PMH, then recovery, SWB and functioning will also increase. At the same time, interventions should be carried out to boost insight, since increasing PMH could decrease insight, all resulting in better quality of life for patients with psychotic disorder.

Abstract
OBJECTIVE Variation in prescription of psychotropic medications to patients with schizophrenia spectrum disorders may underlie health inequities. Using a national U.S. Medicaid sample, the authors examined prescription patterns of psychotropic medications commonly used for managing schizophrenia. METHODS Data from the 2011-2012 Medicaid Analytic eXtract were examined for demographic predictors of and variation across states in psychotropic medication prescription among adult patients diagnosed as having schizophrenia spectrum disorders (N=357,914). Percentages of patients in each state who filled prescriptions of at least 15 days of any antipsychotic, clozapine, antidepressant, benzodiazepine, mood stabilizer, or long-acting injectable (LAI) antipsychotic medication were determined after adjustment for demographic and clinical covariates. Multivariate regressions of clinical and demographic factors predicting prescription patterns were conducted. RESULTS Prescribing patterns for all types of psychotropic medications varied across states. Clozapine and LAI prescriptions showed the most dramatic differences across states and among patients with different demographic characteristics. Across states, adjusted proportions of prescriptions ranged from 4% to 22% for LAIs and from 1% to 11% for clozapine. Non-Hispanic Blacks and people of other race-ethnicities were more likely than non-Hispanic Whites to fill prescriptions for LAIs, and non-Hispanic Whites were more likely than individuals from other racial-ethnic groups to fill prescriptions for clozapine and all other medications. CONCLUSIONS Considerable variation in prescribing patterns of LAIs and clozapine by race-ethnicity and across states suggests uneven quality of care for individuals with schizophrenia spectrum disorders in the United States. A better understanding of what causes this variation could inform policy makers to improve treatment for this vulnerable population.

Abstract
Although the optimal dosing of an antipsychotic medication is known to be essential in the long-term management of schizophrenia, in case of novel drugs such as cariprazine, determining the right dosing strategy is not that simple. Without decades of experience with a particular compound, evidence regarding dosing and titration comes primarily from double-blind, placebo controlled clinical trials that are not necessarily mirroring the real-life experiences of doctors. Via summarizing data from both clinical data (n = 3275) and real-world evidence (observational study n = 116, case studies n = 29), this perspective paper aims to shed a light on the appropriate dosing strategies of cariprazine from treatment initiation through switching strategies to concomitant medications.

Abstract
PURPOSE Little is known about the impact of different psychotropic drugs on acute readmission risk, when used concomitantly in a real-life setting. We aimed to investigate the association between acute readmission risk and use of antipsychotic drugs, antidepressants, mood stabilizers, and benzodiazepines in patients with schizophrenia. METHODS A cohort study included all patients diagnosed with schizophrenia admitted to a psychiatric acute unit at Haukeland University Hospital in Bergen, Norway, during a 10-year period (N = 663). Patients were followed from discharge until first readmission or censoring. Cox multiple regression analyses were conducted using antipsychotic drugs, antidepressants, mood stabilizers, and benzodiazepines as time-dependent variables, and periods of use and nonuse were compared within individual patients. Adjustments were made for sex, age at index admission, and excessive use of alcohol and illicit substances. RESULTS A total of 410 patients (61.8%) were readmitted during follow-up, and the mean and median times in days to readmission were 709 and 575, respectively. Compared with nonuse, the use of antipsychotic drugs was associated with reduced risk of readmission (adjusted hazards ratio, 0.20; P < 0.01; confidence interval, 0.16-0.24), and the use of benzodiazepines was associated with increased risk of readmission (adjusted hazards ratio, 1.51; P < 0.01; confidence interval, 1.13-2.02). However, no relation to readmission risk was found for the use of antidepressants and mood stabilizers. CONCLUSIONS We found that use of benzodiazepines and antipsychotic drugs are inversely associated with acute readmission risk in schizophrenia.

Abstract
Schizophrenia is a debilitating illness with a lifetime prevalence estimate of 0.6% and consists of symptoms from the positive, negative, and cognitive domains. Social support, therapy, psychoeducation, and overall case management are very important aspects of the treatment of schizophrenia. However, as abnormalities in neurotransmission are one of the key findings of schizophrenia pathology, pharmacotherapies are cornerstones of the management of schizophrenia. Antipsychotics have been used as the primary pharmacological treatment of schizophrenia. These agents often have a good effect on reducing positive symptoms, but may not markedly improve negative symptoms or cognitive defects. However, at least 20% of individuals with schizophrenia do not experience a substantial response from monotherapy with antipsychotics. Further, despite evolving treatment protocols and advances in early recognition of the disorder, 70% of patients with schizophrenia require long-term, even lifetime, medication to control their symptoms and do not achieve complete recovery. To address these shortcomings, clinicians and research scientists have explored different combinations of treatments, polypharmacy, to improve the treatment of patients. Antipsychotic polypharmacy has been shown to cause more side effects than monotherapy, which is the main reason why most treatment guidelines caution against it. Antipsychotic monotherapy should be strived for and clozapine should be tried at the latest if two monotherapy trials with other antipsychotics have failed and no absolute contraindications exist. If residual symptoms exist despite trials of adequate dose and duration, other reasons that may reduce treatment effect should be ruled out. Long-acting injectables or blood concentration measurements should be considered to affirm compliance and proper serum levels. Antipsychotic polypharmacy should be considered and discussed with patients from whom the aforementioned procedures do not produce a satisfactory treatment result. In some cases, antipsychotic polypharmacy may produce better results than other forms of treatment augmentation, such as benzodiazepines. In particular, combining aripiprazole with clozapine may be effective in reducing treatment side effects or residual symptoms, and this is likely to hold true for combining other partial dopamine D2 agonists with clozapine as well, although currently scant data exist. More research is needed, both in controlled but also real-world settings, to define optimal antipsychotic polypharmacy and/or other psychotropic treatment augmentation strategies for specific patient groups and situations.

Abstract
AIMS To evaluate the effects of mindfulness-based intervention on psychotic symptoms, positive symptoms, negative symptoms, depressive symptoms, anxiety, and rehospitalization. DESIGN A meta-analysis of randomized controlled trials. DATA SOURCES Medline, Embase, Cochrane Central Register of Controlled Trials, PsycINFO, CINAHL, National Digital Library of Theses and Dissertations in Taiwan, and Airiti Library were searched from their earliest available date up to April 2019. REVIEW METHODS The guidelines of the Cochrane Collaboration were followed to report this systematic review. Two authors conducted this meta-analysis independently. RESULTS Nine randomized controlled trials were included. Meta-analysis showed that mindfulness-based intervention significantly decreased psychotic symptoms, positive symptoms, negative symptoms, depressive symptoms, and duration of rehospitalization among patients with schizophrenia, and that the reduction in negative symptoms lasted through short-term follow-up. The moderation analysis showed that significantly decreased positive symptoms occurred in the nurse-led intervention group, while no significant impact was found in the psychologist-led intervention group. CONCLUSION The psychotic symptoms of the patients with schizophrenia are improved after mindfulness-based intervention and the effects on the negative symptoms can be maintained for at least 3 to 6 months. Mindfulness-based intervention provided by nurses produces more improvements in positive symptoms than intervention provided by psychologists. IMPACT A growing number of mindfulness-based interventions have been implemented for patients with schizophrenia, although the effectiveness had not previously been established by meta-analysis. Mindfulness-based interventions appear to reduce the symptom severity of schizophrenia patients. Further suggestions for healthcare providers and researchers are provided and discussed.

Abstract
AIMS An association between antibody deficiency and clozapine use in individuals with schizophrenia has recently been reported. We hypothesised that if clozapine-associated hypogammaglobulinaemia was clinically relevant this would manifest in referral patterns. METHODS Retrospective case note review of patients referred and assessed by Immunology Centre for Wales (ICW) between January 2005 and July 2018 with extraction of clinical and immunological features for individuals with diagnosis of schizophrenia-like illness. RESULTS 1791 adult patients were assessed at ICW during this period; 23 patients had a psychiatric diagnosis of schizophrenia or schizoaffective disorder. Principal indications for referral were findings of low calculated globulin and immunoglobulins. Clozapine was the single most commonly prescribed antipsychotic (17/23), disproportionately increased relative to reported use in the general schizophrenia population (OR 6.48, 95% CI: 1.79 to 23.5). Clozapine therapy was noted in 6/7 (86%) of patients subsequently requiring immunoglobulin replacement therapy (IgRT). Marked reduction of class-switched memory B cells (CSMB) and plasmablasts were observed in clozapine-treated individuals relative to healthy age-matched controls. Clozapine duration is associated with CSMB decline. One patient discontinued clozapine, with gradual recovery of IgG levels without use of IgRT. CONCLUSIONS Our findings are consistent with enrichment of clozapine-treatment within schizophrenic individuals referred for ICW assessment over the last 13 years. These individuals displayed clinical patterns closely resembling the primary immunodeficiency common variable immunodeficiency, however appears reversible on drug cessation. This has diagnostic, monitoring and treatment implications for psychiatry and immunology teams and directs prospective studies to address causality and the wider implications for this patient group.

Mortality risk from long-term treatment with antipsychotic polypharmacy vs monotherapy among adults with serious mental illness: A systematic review and meta-analysis of observational studies. Schizophr Res 2020; 223:18-28. [PMID: 32948381 DOI: 10.1016/j.schres.2020.08.026] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2020] [Revised: 08/21/2020] [Accepted: 08/29/2020] [Indexed: 11/29/2022]
Abstract
BACKGROUND Long-term use of more than one concurrent antipsychotic [antipsychotic polypharmacy (APP)] is widely believed to contribute to excess mortality in people with serious mental illness (SMI) compared to those taking only one antipsychotic (monotherapy). However, no conclusive evidence is available. METHODS We conducted a systematic search in 6 major electronic databases from inception until December 2019, identifying observational studies examining the association between mortality and exposure to long-term APP vs monotherapy. Studies were eligible if they adopted a follow-up design and antipsychotic exposure was >3 months among adults with SMI. We determined the pooled mortality risk using random-effects meta-analyses. The review was registered in PROSPERO (CRD42019148044). RESULTS A total of 12 studies fulfilled all eligibility criteria reporting quantitative data for 834, 534 person years. No difference was found in the association between all-cause mortality and APP vs monotherapy use, in both crude (rate ratio = 0.94, 95% CI 0.81-1.10, p = 0.446; I2 = 83.2%, p < 0.001; 10 studies) and adjusted models (adjusted HR = 0.98, 95% CI 0.80-1.19, p = 0.802; I2 = 58.3%, p < 0.05; 5 studies). Meta-regression did not identify any moderators influencing all-cause mortality risk. For natural causes of death, risk estimates followed the same pattern: (i) crude rate ratio = 0.88, 95% CI 0.67-1.14, p = 0.324; I2 = 77.7%, p = 0.01 (5 studies); (ii) adjusted HR = 1.04, 95% CI 0.90-1.99, p = 0.590; I2 = 0.0%, p = 0.744 (5 studies). CONCLUSION Mortality risk of APP use in people with SMI appears to be comparable to that of monotherapy use, although work to date remains heterogeneous, precluding firm conclusions from made. Complex real-world clinical scenarios may be contributing to this lack of variation between these two types of antipsychotic use.

Abstract
OBJECTIVES Data on psychotropic medications of older patients with schizophrenia spectrum disorder are scarce. Specifically, information about the use of benzodiazepines among older patients with schizophrenia spectrum disorder is very limited. Because benzodiazepine use in older patients has been associated with many disabling side effects, its use in actual practice must be described and questioned. This study aimed at exploring the prevalence of benzodiazepine use and the clinical factors associated with such use among older patients with schizophrenia spectrum disorder. METHODS/DESIGN Data from the Cohort of individuals with Schizophrenia Aged 55 years or more (CSA) were used to examine the prevalence of benzodiazepine use among older patients with schizophrenia spectrum disorder. Demographic and clinical characteristics associated with benzodiazepine prescription were also explored. RESULTS The prevalence of benzodiazepine use was 29.8% of older patients with schizophrenia spectrum disorder. These patients were significantly more likely to have medical comorbidities, cognitive and social functioning impairments, to report a lifetime history of suicide attempt, to be institutionalized, and to have been hospitalized in a psychiatric service in the past year compared to those without a benzodiazepine prescription (all p<0.05). There were no between-group differences in schizophrenia severity and psychiatric comorbidity. CONCLUSIONS Although it can be hypothesized that benzodiazepine prescription is part of a short-term therapeutic strategy toward patients with more severe trouble or comorbid disorders, our results suggest a strong link between benzodiazepine prescription and a particularly vulnerable subpopulation of older patients with schizophrenia spectrum disorder.

Abstract
Objective: To evaluate the effectiveness of 6-month treatment with aripiprazole long-acting injectable (LAI) in improving psychotic symptoms, social functioning and side effects and reducing co-administered antipsychotic drugs.Methods: Multicentre, observational, prospective study that enrolled 53 patients with diagnosis of schizophrenia spectrum disorders who initiated or switched to aripiprazole LAI. The effectiveness of aripiprazole LAI was assessed through the Positive and Negative Syndrome Scale (PANSS), the Udvalg for Kliniske Undersogelser scale for side effects, the Global Assessment of Functioning and the Clinical Global Impression-Schizophrenia (CGI-SCH).Results: Upon treatment with aripiprazole LAI, patients significantly improved all the domains of PANSS (p < .05). Adverse event severity significantly improved after a 6-month aripiprazole LAI treatment (p < .05). Differences from baseline to month 6 in Global Assessment of Functioning score were significant (p = .0002). The proportion of severely ill patients decreased upon treatment with aripiprazole LAI (CGI-SCH scale). Prolactin levels were normalised after a 6-month treatment (from 43.0 to 14.7 ng/mL). Co-administered antipsychotic drugs significantly decreased after a 6-month treatment with aripiprazole LAI.Conclusion: A 6-month treatment with aripiprazole LAI improved the clinical status of our patients without modifying their metabolic profile, and allowed the reduction of co-administered antipsychotic drugs.Practice implicationsLong-acting injectable antipsychotics are effective treatment options for the maintenance of patients with schizophrenia and related disorders, and to ensure treatment adherence. This study describes the evolution of patients over six months of treatment with aripiprazole long-acting injectable. The results from this study support previous data on the efficacy and safety of this atypical antipsychotic. This study may be of wide interest to the community of psychiatrists and may help clinicians optimise treatment adherence in patients with schizophrenia spectrum disorders.Key pointsAripiprazole long-acting injectable is an atypical antipsychotic intended to improve treatment adherence and prevent relapses.This multicentre prospective study evaluated the effectiveness of aripiprazole long-acting injectable over six months of treatment on the control of a comprehensive set of clinical variables.Clinical rating scales showed that treatment with aripiprazole long-acting injectable improved clinical symptoms and social functioning, and reduced the severity of adverse events.Aripiprazole long-acting injectable contributed to the maintenance of adequate metabolic profiles and the normalisation of prolactin levels.Patients significantly decreased co-administered antipsychotic drugs after 6-month treatment with aripiprazole.

Abstract
These updated guidelines from the British Association for Psychopharmacology replace the original version published in 2011. They address the scope and targets of pharmacological treatment for schizophrenia. A consensus meeting was held in 2017, involving experts in schizophrenia and its treatment. They were asked to review key areas and consider the strength of the evidence on the risk-benefit balance of pharmacological interventions and the clinical implications, with an emphasis on meta-analyses, systematic reviews and randomised controlled trials where available, plus updates on current clinical practice. The guidelines cover the pharmacological management and treatment of schizophrenia across the various stages of the illness, including first-episode, relapse prevention, and illness that has proved refractory to standard treatment. It is hoped that the practice recommendations presented will support clinical decision making for practitioners, serve as a source of information for patients and carers, and inform quality improvement.

Abstract
IMPORTANCE People with schizophrenia are commonly treated with psychotropic medications in addition to antipsychotics, but there is little evidence about the comparative effectiveness of these adjunctive treatment strategies. OBJECTIVE To study the comparative real-world effectiveness of adjunctive psychotropic treatments for patients with schizophrenia. DESIGN, SETTING, AND PARTICIPANTS This comparative effectiveness study used US national Medicaid data from January 1, 2001, to December 31, 2010, to examine the outcomes of initiating treatment with an antidepressant, a benzodiazepine, a mood stabilizer, or another antipsychotic among adult outpatients (aged 18-64 years) diagnosed with schizophrenia who were stably treated with a single antipsychotic. Data analysis was performed from January 1, 2017, to June 30, 2018. Multinomial logistic regression models were used to estimate propensity scores to balance covariates across the 4 medication groups. Weighted Cox proportional hazards regression models were used to compare treatment outcomes during 365 days on an intention-to-treat basis. MAIN OUTCOMES AND MEASURES Risk of hospitalization for a mental disorder (primary), emergency department (ED) visits for a mental disorder, and all-cause mortality. RESULTS The study cohort included 81 921 adult outpatients diagnosed with schizophrenia (mean [SD] age, 40.7 [12.4] years; 37 515 women [45.8%]) who were stably treated with a single antipsychotic and then initiated use of an antidepressant (n = 31 117), a benzodiazepine (n = 11 941), a mood stabilizer (n = 12 849), or another antipsychotic (n = 26 014) (reference treatment). Compared with initiating use of another antipsychotic, initiating use of an antidepressant was associated with a lower risk (hazard ratio [HR], 0.84; 95% CI, 0.80-0.88) of psychiatric hospitalization, whereas initiating use of a benzodiazepine was associated with a higher risk (HR, 1.08; 95% CI, 1.02-1.15); the risk associated with initiating use of a mood stabilizer (HR, 0.98; 95% CI, 0.94-1.03) was not significantly different from initiating use of another antipsychotic. A similar pattern of associations was observed in psychiatric ED visits for initiating use of an antidepressant (HR, 0.92; 95% CI, 0.88-0.96), a benzodiazepine (HR, 1.12; 95% CI, 1.07-1.19), and a mood stabilizer (HR, 0.99; 95% CI, 0.94-1.04). Initiating use of a mood stabilizer was associated with an increased risk of mortality (HR, 1.31; 95% CI, 1.04-1.66). CONCLUSIONS AND RELEVANCE In the treatment of schizophrenia, initiating adjunctive treatment with an antidepressant was associated with reduced risk of psychiatric hospitalization and ED visits compared with initiating use of alternative psychotropic medications. Associations of benzodiazepines and mood stabilizers with poorer outcomes warrant clinical caution and further investigation.

Adipokine levels are associated with insulin resistance in antipsychotics users independently of BMI. Psychoneuroendocrinology 2019; 103:87-95. [PMID: 30659986 DOI: 10.1016/j.psyneuen.2019.01.001] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2018] [Revised: 11/24/2018] [Accepted: 01/03/2019] [Indexed: 01/10/2023]
Abstract
BACKGROUND The prevalence of obesity, metabolic syndrome and type 2 diabetes mellitus is increased among patients with severe mental disorders, and particularly use of second generation antipsychotic drugs is associated with metabolic side effects. Antipsychotics have been found to alter levels of adipokines which regulate insulin sensitivity, but their role in antipsychotic-associated insulin resistance is not established, and it is unclear whether adipokines affect insulin resistance independently of body mass index (BMI). METHODS We included 1050 patients with severe mental disorders and 112 healthy controls aged 18-65 years from the Oslo area, Norway. Clinical variables, BMI and use of medication were assessed, fasting blood samples were obtained for calculation of the leptin/adiponectin ratio (L/A ratio) and estimate of insulin resistance using the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR). Case-control analyses were followed by mediation analyses to evaluate the possible direct effect of antipsychotics on HOMA-IR and indirect effect mediated via the L/A ratio. This was performed both with and without adjustment for BMI, in the total sample and in an antipsychotic monotherapy subsample (N = 387). RESULTS BMI, L/A ratio and HOMA-IR were significantly higher in patients than controls (p < 0.001-p = 0.01). There was a significant direct effect from use of antipsychotics in general on HOMA-IR both without (b = 0.03, p = 0.007) and with adjustment for BMI (b = 0.03, p = 0.013), as well as a significant mediating effect via L/A ratio both without (b = 0.03, p < 0.001) and with adjustment for BMI (b = 0.01, p = 0.041). Use of olanzapine (b = 0.03, p < 0.001) or aripiprazole (b = 0.04, p < 0.001) in monotherapy showed significant effects on HOMA-IR mediated via L/A ratio. CONCLUSIONS The study suggests that use of antipsychotics may alter adipokine levels, and that increased L/A ratio may play a role in the development of insulin resistance associated with use of antipsychotics also independently of BMI.

Abstract
Aims Several drugs increase the risk of ventricular fibrillation and sudden cardiac death (SCD). We aimed to investigate in detail the toxicological findings of all young SCD throughout Denmark. Methods and results Deaths in persons aged 1-49 years were included over a 10-year period. Death certificates and autopsy reports were retrieved and read to identify cases of sudden death and establish cause of death. All medico-legal autopsied SCD were included and toxicological reports collected. Positive toxicology was defined as the presence of any substance (licit and/or illicit). All toxicological findings had previously been evaluated not to have caused the death (i.e. lethal concentrations were excluded). We identified 620 medico-legal autopsied cases of SCD, of which 77% (n = 477) were toxicologically investigated post-mortem, and 57% (n = 270) had a positive toxicology profile. Sudden cardiac death with positive toxicology had higher rates of sudden arrhythmic death syndrome (SADS), compared with SCD with negative toxicology (56% vs. 42%, P < 0.01). In total, 752 agents were detected, and polypharmacy (defined as the presence of more than one drug) was present in 61% (n = 164), all substances combined. Psychotropic drugs were the most frequent (62%, n = 467), and 82% (n = 385) were in pharmacological or subpharmacological levels. Conclusion We found that more than half of all toxicologically investigated SCD victims have positive post-mortem toxicological findings, and polypharmacy is displayed in a considerable proportion. SCD with positive toxicology had higher rate of SADS, suggesting that the compounds may play a proarrhythmic role in these cases.

Abstract
OBJECTIVE While "dual diagnosis" involving both psychiatric and substance use disorders has long been a focus of schizophrenia research, recent studies have advocated for a shift of focus to multimorbidity, addressing comorbidity from both additional psychiatric disorders and substance use disorders. We hypothesized that more extensive mental health multimorbity would be associated with poorer quality of life (QOL) and functioning, and that additional psychiatric comorbidity in schizophrenia would have similar adverse effects on QOL as substance use comorbidity. METHODS Participants with schizophrenia in the NIMH-funded Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) were classified using baseline diagnostic data into four groups: 1) monomorbid schizophrenia: 2) additional psychiatric comorbidity, 3) additional substance use comorbidity, and 4) both additional psychiatric and substance use comorbidity. Mixed models compared groups on self-reported QOL (SF-12 and Lehman QOLI) and rater-evaluated QOL (the Quality of Life Scale) using baseline, 6, 12 and 18-month follow-up data. RESULTS As hypothesized, patients with schizophrenia alone had a better QOL than those with any multimorbidity; patients with both psychiatric and substance use comorbidities had a worse QOL than those with fewer comorbidities; and patients with comorbid substance use alone were not significantly worse off than those with comorbid psychiatric disorder. CONCLUSION The multimorbidity framework more richly differentiates complex clinical presentations of schizophrenia than the current dual diagnosis concept and deserves further study as to its etiology, consequences, and treatment.

Abstract
OBJECTIVE To compare treatment patterns and Medicaid spending between schizophrenia patients initiating once-monthly paliperidone palmitate (PP1M) and oral atypical antipsychotics (OAAs) within four comorbid populations: cardiovascular disease (CVD), diabetes, hypertension and obesity. METHODS Five-state Medicaid data identified comorbid adults with schizophrenia initiating PP1M or OAAs (index) from September 2009 balanced with inverse probability of treatment weighting. Chi-squared and t-tests compared index antipsychotic (AP) exposure (no gap >90 days) duration, AP polypharmacy, and index AP adherence (proportion of days covered ≥80%) and persistence (no gap ≥60 days) at 12 months post-index. Linear models with a non-parametric bootstrap procedure compared costs. RESULTS PP1M patients consistently had longer index AP exposure (e.g. CVD: 244 vs. 189 days; p < .001) and less AP polypharmacy (e.g. CVD: 21.1% vs. 28.1%; p < .001) versus OAA patients. Relative to OAA patients, adherence was more likely in PP1M patients with CVD or obesity (e.g. CVD: 28.6% vs. 22.1%; p < .001) and less likely for patients with diabetes (22.0% vs. 24.4%; p = .031). Persistence was consistently more likely for PP1M versus OAA patients (e.g. CVD: 49.9% vs. 27.4%; p < .001). Total costs were not significantly different between PP1M and OAA patients for any comorbidity. PP1M patients with diabetes, hypertension or obesity had higher pharmacy and lower medical costs (all p < .05). CONCLUSIONS Treatment with PP1M versus OAAs may reduce AP polypharmacy and increase AP persistence in comorbid patients with schizophrenia, without increasing total healthcare costs. Comorbidities are a highly prevalent driver of excess mortality in this vulnerable population; thus, future studies should specifically address the real-world effectiveness of therapies, including long acting injectable therapies (LAIs), for these patients.

Abstract
OBJECTIVE Individuals with psychotic-spectrum disorders use tobacco and cannabis at higher rates than the general population and individuals with other psychiatric disorders, which may contribute to increased rates of medical problems and mortality. The present study examined whether individuals with psychosis and comorbid tobacco and/or cannabis use disorders exhibit differing clinical characteristics in terms of their sociodemographic, mental health, substance use, physical health, and medication use patterns. Elucidation of these profiles, and determining their relative severity, has important implications for treatment, including offering more targeted interventions based on type of comorbidity pattern. METHODS We examined the electronic medical records of 829 patients with psychotic-spectrum disorders admitted to a psychiatric hospital and categorized them as having: (1) cannabis use disorder (CUD); (2) tobacco use disorder (TUD); (3) comorbid cannabis and tobacco use disorders (CUD + TUD); or (4) neither disorder (no CUD/TUD). Multinomial logistic regression was used to compare the aforementioned groups on multiple variables controlling for age and sex. RESULTS Alcohol and stimulant use disorder diagnoses were each related to higher odds of having a CUD and CUD + TUD, relative to no CUD/TUD. Stimulant and polysubstance use disorder diagnoses were each related to higher odds of having a TUD compared to no CUD/TUD. Greater number of prescribed psychotropic medications was related to higher odds of a TUD compared to no CUD/TUD. CONCLUSIONS Although several differences between groups were accounted for by age of cannabis versus tobacco users, findings point to the importance of considering comorbid alcohol and substance use disorders among those with psychosis and CUD/TUD, as these comorbidities have important implications for screening and treatment selection during and following acute hospitalization.

Abstract
BACKGROUND Current evidence-based guidelines provide unclear support for many common polypharmacy practices in schizophrenia. Excessive or complex polypharmacy (≥4 psychotropics) has been studied in patients with bipolar disorder, but not in schizophrenia to date. METHODS We conducted a digital medical record data extraction of 829 patients consecutively admitted to a psychiatric hospital and diagnosed as having schizophrenia-spectrum disorders. RESULTS In those prescribed psychiatric medication preadmission, 28.1% (n = 169) met the criteria for complex polypharmacy. Complex polypharmacy patients were older, female, white, and disabled, and had more comorbidities compared with those without complex polypharmacy. In multivariable analysis, complex polypharmacy was specifically associated with being white and disabled, and having a comorbid anxiety disorder, tobacco use disorder, metabolic condition, and neurological condition compared with noncomplex polypharmacy patients. CONCLUSIONS Although there is little evidence to support complex polypharmacy in schizophrenia, rates were relatively high in patients requiring hospitalization, especially when they are also diagnosed as having comorbid psychiatric and medical conditions. Future research is needed to study the risk-benefit profile for these patients, especially considering their higher medical burden and related health risks.

Abstract
BackgroundDepression in schizophrenia predicts poor outcomes, including suicide, yet the effectiveness of antidepressants for its treatment remains uncertain.AimsTo synthesise the evidence of the effectiveness of antidepressants for the treatment of depression in schizophrenia.MethodMultiple databases were searched and inclusion criteria included participants aged over 18 years with schizophrenia or related psychosis with a depressive episode. Papers were quality assessed used the Cochrane risk bias tool. Meta-analyses were performed for risk difference and standardised mean difference of all antidepressants, antidepressant class and individual antidepressant where sufficient studies allowed.ResultsA total of 26 moderate- to low-quality trials met inclusion criteria. In meta-analysis a significant risk difference was found in favour of antidepressant treatment, with a number needed to treat of 5 (95% CI 4-9). Studies using tools specifically designed to assess depression in schizophrenia showed a larger effect size. However, after sensitivity analysis standardised mean difference of all antidepressants did not show a statistically significant improvement in depression score at end-point, neither did any individual antidepressant class.ConclusionsAntidepressants may be effective for the treatment of depression in schizophrenia, however, the evidence is mixed and conclusions must be qualified by the small number of low- or moderate-quality studies. Further sufficiently powered, high-quality studies are needed.

Immune activation in lactating dams alters sucklings' brain cytokines and produces non-overlapping behavioral deficits in adult female and male offspring: A novel neurodevelopmental model of sex-specific psychopathology. Brain Behav Immun 2017; 63:35-49. [PMID: 28189716 DOI: 10.1016/j.bbi.2017.01.015] [Citation(s) in RCA: 23] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2016] [Revised: 12/26/2016] [Accepted: 01/23/2017] [Indexed: 01/04/2023] Open
Abstract
Early immune activation (IA) in rodents, prenatal through the mother or early postnatal directly to the neonate, is widely used to produce behavioral endophenotypes relevant to schizophrenia and depression. Given that maternal immune response plays a crucial role in the deleterious effects of prenatal IA, and lactation is a critical vehicle of immunological support to the neonate, we predicted that immune activation of the lactating dam will produce long-term abnormalities in the sucklings. Nursing dams were injected on postnatal day 4 with the viral mimic poly-I:C (4mg/kg) or saline. Cytokine assessment was performed in dams' plasma and milk 2h, and in the sucklings' hippocampus, 6h and 24h following poly-I:C injection. Male and female sucklings were assessed in adulthood for: a) performance on behavioral tasks measuring constructs considered relevant to schizophrenia (selective attention and executive control) and depression (despair and anhedonia); b) response to relevant pharmacological treatments; c) brain structural changes. Maternal poly-I:C injection caused cytokine alterations in the dams' plasma and milk, as well as in the sucklings' hippocampus. Lactational poly-I:C exposure led to sex-dimorphic (non-overlapping) behavioral abnormalities in the adult offspring, with male but not female offspring exhibiting attentional and executive function abnormalities (manifested in persistent latent inhibition and slow reversal) and hypodopaminergia, and female but not male offspring exhibiting despair and anhedonia (manifested in increased immobility in the forced swim test and reduced saccharine preference) and hyperdopaminergia, mimicking the known sex-bias in schizophrenia and depression. The behavioral double-dissociation predicted distinct pharmacological profiles, recapitulating the pharmacology of negative/cognitive symptoms and depression. In-vivo imaging revealed hippocampal and striatal volume reductions in both sexes, as found in both disorders. This is the first evidence for the emergence of long-term behavioral and brain abnormalities after lactational exposure to an inflammatory agent, supporting a causal link between early immune activation and disrupted neuropsychodevelopment. That such exposure produces schizophrenia- or depression-like phenotype depending on sex, resonates with notions that risk factors are transdiagnostic, and that sex is a susceptibility factor for neurodevelopmental psychopathologies.

Abstract
Contexte Cet article vise à décrire les facteurs associés à la prescription d’antipsychotiques par un psychiatre plutôt qu’un omnipraticien, la prescription d’un antipsychotique de seconde plutôt que de première génération, la prescription d’une multithérapie d’antipsychotiques et le non-renouvellement de la prescription initiale.
Méthodologie Il s’agit d’une étude pharmacoépidémiologique observationnelle avec analyses secondaires d’une banque de données médicoadministratives (RAMQ). Les données disponibles portaient sur un échantillon exhaustif des personnes adultes ayant reçu un diagnostic de schizophrénie et ayant obtenu un antipsychotique couvert par le régime public d’assurance médicaments de 1998 à 2006. Les résultats de régression logistique multiple sont rapportés.
Résultats Parmi les 16 225 personnes éligibles, 46,2 % étaient des femmes et 70 % étaient bénéficiaires d’une aide financière. La clientèle des psychiatres était plus jeune et plus atteinte au niveau de la santé mentale. La multithérapie était associée aux hospitalisations pour psychose, au faible statut socio-économique et à un âge entre 35 et 64 ans. Les antipsychotiques de seconde génération ont pris une place importante au cours de la période à l’étude. Le non-renouvellement était associé à l’abus de substances et était moins fréquent suite à une hospitalisation pour trouble mental.
Conclusions Malgré les limites liées à l’utilisation de données administratives, l’utilisation d’une banque de données exhaustive provenant autant de médecine générale que de spécialité permet à cette étude de brosser un portrait populationnel pertinent pour connaître la situation réelle du traitement incident de la schizophrénie au Québec de 1998 à 2006, une période caractérisée par l’introduction des antipsychotiques de seconde génération.

Abstract
Objective: The aim of our study was to examine the prevalence of and factors associated with antipsychotic polypharmacy (APP) among patients with serious mental illness in the current South African health care context. Methods: We collected data on patient, illness, and treatment characteristics of patients discharged on one or more antipsychotic agents from January to June 2014. We analyzed the associations of APP with demographic and clinical variables using hierarchical multivariable logistic regression, and examined prescription patterns. Results: The prevalence of APP in our study population of 577 patients was 28.4%. Demographic and clinical characteristics significantly associated with APP included age > 29, male sex, diagnosis of schizophrenia, comorbid intellectual disability, comorbid substance use, greater number of hospital admissions, and high-dose prescribing. First-generation antipsychotics and long-acting injectable preparations were prominent in APP combinations. Co-prescription of anticholinergic agents and sodium valproate demonstrated a significant association with APP. Conclusion: APP appears common in our population, despite lack of evidence for the practice and possible risk of harm. Our findings suggest a complex interplay among patient, illness, and treatment factors relevant to APP in our setting that could be targeted for intervention.

Abstract
OBJECTIVE The aim of this study was to observe potential drug-drug interactions in the medication of Mexican schizophrenic patients. METHODS We performed a retrospective and cross-sectional study that was carried out in a psychiatric clinic. Only the prescriptions of patients with schizophrenia whose diagnoses were based on the DSM-IV instrument were included in this study. The Drug Interactions Checker software ( http://www.drugs.com/drug_interactions.html ) was used in this study to analyse potential drug-drug interactions. RESULTS In total, 86 of 126 patients were at risk of potential drug-drug interactions. Haloperidol and biperiden was the most common drug pair of 232 pairs evaluated. In our study, 13.8% of drug-drug interaction showed a major level of severity, whereas in 83.2%, the interaction was moderate. Finally, central nervous system (CNS) depression and anticholinergic effect were the main possible effects of drug-drug interaction. CONCLUSIONS Our results revealed a high number of patients with schizophrenia receiving two or more drugs. The potential drug-drug interactions observed in the Mexican population are consistent with the concomitant use of antipsychotics, benzodiazepines, and antidepressants prescribed in schizophrenia that could cause central nervous system (CNS) depression and anticholinergic effect. Drug-drug interaction must be considered when the patient with schizophrenia is medicated.

Antipsychotic Medication Prescribing Practices Among Adult Patients Discharged From State Psychiatric Inpatient Hospitals. J Psychiatr Pract 2016; 22:283-97.

Abstract
OBJECTIVES The goal of this study was to explore antipsychotic medication prescribing practices in a sample of 86,034 patients discharged from state psychiatric inpatient hospitals and to find the prevalence of patients discharged with no antipsychotic medications, on antipsychotic monotherapy, and on antipsychotic polypharmacy. For patients discharged on antipsychotic polypharmacy, the study explored the adjusted rates of antipsychotic polypharmacy, the reasons patients were discharged on antipsychotic polypharmacy, the proportion of antipsychotic polypharmacy by mental health disorder, and the characteristics associated with being discharged on antipsychotic polypharmacy. METHODS This cross-sectional study analyzed all discharges for adult patients (18 to 64 y of age) from state psychiatric inpatient hospitals between January 1 and December 31, 2011. The relationship among variables was explored using χ, t test, and analysis of variance. Logistic regression was used to determine predictors of antipsychotic polypharmacy. RESULTS The prevalence of antipsychotic polypharmacy was 12%. Of the discharged patients receiving at least 1 antipsychotic medication (adjusted rate), 18% were on antipsychotic polypharmacy. The strongest predictors of antipsychotic polypharmacy being prescribed were having a diagnosis of schizophrenia and a length of stay of 90 days or more. Patients were prescribed antipsychotic polypharmacy primarily to reduce their symptoms. CONCLUSIONS Antipsychotic polypharmacy continues at a high enough rate to affect nearly 10,000 patients with a diagnosis of schizophrenia each year in state psychiatric inpatient hospitals. Further analysis of the clinical presentation of these patients may highlight particular aspects of the illness and its previous treatment that are contributing to practices outside the best-practice guideline. An increased understanding of trend data, patient characteristics, and national benchmarks provides an opportunity for decision-making that is sensitive to the patient's needs and cognizant of the hospital's accomplishments in adopting best practices.

Abstract
We have recently proposed a model for subtyping schizophrenia based on antipsychotic (AP) treatment response. Evidence suggests that APs, both old and new, are comparable in terms of efficacy; however, one AP, clozapine, is uniquely effective in one subgroup of patients (that is, those with treatment-resistant schizophrenia [TRS]). This permits us to subdivide schizophrenia into 3 specific groups: AP responsive, clozapine responsive, and clozapine resistant. Here, we integrate this model with current criteria related to TRS and ultraresistant schizophrenia, the latter referred to in our model as clozapine resistant. We suggest several modifications to existing criteria, in line with current evidence and practice patterns, particularly emphasizing the need to focus on positive symptoms. While APs can favourably impact numerous dimensions related to schizophrenia, it is their effect on positive symptoms that distinguishes them from other psychotropics. Further, it is positive symptoms that are central to AP and clozapine resistance, and it is these people that place the greatest demands on acute and long-term inpatient resources. In moving AP development forward, we advocate specifically focusing on positive symptoms and capitalizing on the evidence we have of 3 subtypes of psychosis (that is, positive symptoms) based on treatment response, implicating 3 distinguishable forms of underlying pathophysiology. Conversely, pooling these groups risks obfuscating potentially identifiable differences. Such a position does not challenge the importance of dopamine D2 receptor blockade, but rather highlights the need to better isolate those other subgroups that require something more or entirely different.

Abstract
BACKGROUND Zinc can modulate fast-excitatory transmission, facilitate the release of amino butyric acid and potentiate nicotinic acetylcholine receptors. There are also emerging evidences discussing the implication of these neurotransmitters in pathophysiology of schizophrenia. OBJECTIVES The purpose of this study was to evaluate the efficacy of Zn sulfate as an add-on therapy in the treatment of schizophrenia in a 6-week, double-blind and placebo-controlled trial. PATIENTS AND METHODS Eligible participants were 30 inpatients with schizophrenia according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria. Patients were randomly allocated into two equal groups; one group of patients received risperidone 6 mg/day plus capsules of Zn sulfate (each containing 50 mg elemental Zn) three times a day and another group received risperidone 6 mg/day plus placebo. The Positive and Negative Syndrome Scale (PANSS) was applied to assess the psychotic symptoms and aggression risk at baseline, week 2, 4, and 6 of the study. RESULTS The results of this study showed that both protocols significantly decreased the scores on all subscales of the PANSS and supplemental aggression risk subscale as well as PANSS total score over the study. However, this improvement was significantly higher in Zn sulfate receiving group compared to the placebo group. No major clinical side-effects were detected. CONCLUSIONS It may be concluded that Zn is an effective adjuvant agent in the management of patients with schizophrenia.

Abstract
Clinical development in brain diseases has one of the lowest success rates in the pharmaceutical industry, and many promising rationally designed single-target R&D projects fail in expensive Phase III trials. By contrast, successful older CNS drugs do have a rich pharmacology. This article will provide arguments suggesting that highly selective single-target drugs are not sufficiently powerful to restore complex neuronal circuit homeostasis. A rationally designed multitarget project can be derisked by dialing in an additional symptomatic treatment effect on top of a disease modification target. Alternatively, we expand upon a hypothetical workflow example using a humanized computer-based quantitative systems pharmacology platform. The hope is that incorporating rationally multipharmacology drug discovery could potentially lead to more impactful polypharmacy drugs.

Abstract
Modern neuropsychopharmacology commenced in the 1950s with the serendipitous discovery of first-generation antipsychotics and antidepressants which were therapeutically effective yet had marked adverse effects. Today, a broader palette of safer and better-tolerated agents is available for helping people that suffer from schizophrenia, depression and other psychiatric disorders, while complementary approaches like psychotherapy also have important roles to play in their treatment, both alone and in association with medication. Nonetheless, despite considerable efforts, current management is still only partially effective, and highly-prevalent psychiatric disorders of the brain continue to represent a huge personal and socio-economic burden. The lack of success in discovering more effective pharmacotherapy has contributed, together with many other factors, to a relative disengagement by pharmaceutical firms from neuropsychiatry. Nonetheless, interest remains high, and partnerships are proliferating with academic centres which are increasingly integrating drug discovery and translational research into their traditional activities. This is, then, a time of transition and an opportune moment to thoroughly survey the field. Accordingly, the present paper, first, chronicles the discovery and development of psychotropic agents, focusing in particular on their mechanisms of action and therapeutic utility, and how problems faced were eventually overcome. Second, it discusses the lessons learned from past successes and failures, and how they are being applied to promote future progress. Third, it comprehensively surveys emerging strategies that are (1), improving our understanding of the diagnosis and classification of psychiatric disorders; (2), deepening knowledge of their underlying risk factors and pathophysiological substrates; (3), refining cellular and animal models for discovery and validation of novel therapeutic agents; (4), improving the design and outcome of clinical trials; (5), moving towards reliable biomarkers of patient subpopulations and medication efficacy and (6), promoting collaborative approaches to innovation by uniting key partners from the regulators, industry and academia to patients. Notwithstanding the challenges ahead, the many changes and ideas articulated herein provide new hope and something of a framework for progress towards the improved prevention and relief of psychiatric and other CNS disorders, an urgent mission for our Century.

[PMID: 25619433 DOI: 10.1016/j.psychres.2014.12.046] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/29/2014] [Revised: 12/30/2014] [Accepted: 12/31/2014] [Indexed: 02/05/2023]
Abstract
This study aimed to assess the delay in initiation of clozapine, number of adequate antipsychotic trials prior to starting clozapine and practice of polypharmacy prior to starting clozapine. A retrospective study design was followed. Treatment records of 200 patients started on clozapine during the period of January 2006-June 2014 were reviewed. The mean delay in clozapine initiation was 1.93 (S.D. 1.82) years and median was 1.5 years. Mean of 3 (S.D. 1.18) adequate antipsychotic trials was given prior to considering clozapine and 27.5% patients had received polypharmacy prior to clozapine. Factors related to delay in starting of clozapine included higher age, longer duration of illness, age more than 20 years of age, polypharmacy, use of an adequate trial of typical antipsychotic medication, patients from urban locality and those with onset of illness prior to introduction of clozapine into Indian market. Findings of the present study suggest that there is a delay of 1.5-2 years in starting of clozapine and about one-fourth of patients receive polypharmacy prior to receiving clozapine. These finding suggests that there is a need to change the prescribing habits to reduce the delay in starting of clozapine.

Abstract
OBJECTIVE To examine how advances in our understanding of schizophrenia have shaped thinking about antipsychotics (APs) and their role in treatment. METHOD Three specific developments in the field of schizophrenia are highlighted: advances in knowledge related to the earliest stages of schizophrenia, specifically the prodrome; reconceptualization of schizophrenia as an illness of multiple symptom domains; and greater clarification regarding the efficacy of clozapine and a new generation of APs. RESULTS Evidence indicating that negative and cognitive symptoms are present during the prodrome suggests that intervention at the time of first-episode psychosis constitutes late intervention. The limited efficacy of APs beyond psychosis argues against a magic bullet approach to schizophrenia and for polypharmacy that is symptom domain-specific. Clozapine's unique, but limited, efficacy in treatment resistance supports subtyping schizophrenia based on treatment response. CONCLUSIONS Advances in our understanding of schizophrenia have important implications regarding the current use of APs, expectations regarding response, and future drug development.

Abstract
Insufficient treatment of psychosis often manifests as violent and aggressive behaviors that are dangerous to the patient and others, and that warrant treatment strategies which are not considered first-line, evidence-based practices. Such treatment strategies include both antipsychotic polypharmacy (simultaneous use of 2 antipsychotics) and high-dose antipsychotic monotherapy. Here we discuss the hypothesized neurobiological substrates of various types of violence and aggression, as well as providing arguments for the use of antipsychotic polypharmacy and high-dose monotherapy to target dysfunctional neurocircuitry in the subpopulation of patients that is treatment-resistant, violent, and aggressive. In this review, we focus primarily on the data supporting the use of second-generation, atypical antipsychotics both at high doses and in combination with other antipsychotics.

Abstract
The inaugural Collegium Internationale Neuro-Psychopharmacologicum (CINP) Think Tank, a small open meeting sponsored by the CINP, discussed impediments to developing new drugs for psychiatric disorders and approaches to overcome these impediments. Whilst neuropsycharmacology has a rich pharmacopeia (current treatments benefiting many individuals), issues of treatment resistance, sub-optimal response and unwanted side effects remain problematic. Many scientific, economic and social issues are impeding the development of drugs (e.g. higher risk of failure, placebo effects, problematic regulatory environments, pressures imposed by patent protection, downward pressure on reimbursements and financial, legal and social risk aversion). A consensus of the meeting was that efforts to understanding the core pathophysiology of psychiatric disorders are fundamental to increasing the chance of developing new drugs. However, findings from disorders such as Huntington's chorea, have shown that knowing the cause of a disorder may not reveal new drug targets. By contrast, clinically useful biomarkers that define target populations for new drugs and models that allow findings to be accurately translated from animals to humans will increase the likelihood of developing new drugs. In addition, a greater accent on experimental medicine, creative clinical investigations and improved communication between preclinical neuropsychopharmacologists, clinicians committed to neuropsychopharmacological research, industry and the regulators would also be a driver to the development of new treatments. Finally, it was agreed that the CINP must continue its role as a conduit facilitating vibrant interactions between industry and academia as such communications are a central component in identifying new drug targets, developing new drugs and transitioning new drugs into the clinic.

Schizophr Res 2014; 152:246-54. [PMID: 24275583 DOI: 10.1016/j.schres.2013.10.034] [Citation(s) in RCA: 48] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2013] [Revised: 10/11/2013] [Accepted: 10/25/2013] [Indexed: 11/28/2022]
Abstract
BACKGROUND Leading guidelines recommend antipsychotic (AP) monotherapy for schizophrenia, nonetheless the combination of antipsychotics (polypharmacy) is common practice worldwide. We conducted a nationwide population-based study to investigate the comparative effectiveness of monotherapy versus polypharmacy in schizophrenia and other psychotic disorders. METHODS Data was collected from the Hungarian National Health Insurance Fund's database and a non-interventional retrospective-prospective parallel arm study was designed with a monotherapy arm (MA, switch to a new antipsychotic after >60 days of monotherapy, N=5480) and a polypharmacy arm with two APs (PA, addition of a second antipsychotic after >60 days of monotherapy, N=7901). The analyses focused on therapy changers, who started a new monotherapy or added a new AP to the existing one. Polypharmacy combinations with more than two APs were not investigated. Fourteen APs were investigated representing the majority of marketed antipsychotics of Hungary in the period of 1/2007-12/2009. The principal endpoint was the time to all-cause treatment discontinuation during a one-year observation period. Kaplan-Meier survival analysis and Cox proportional hazards model were applied with propensity score adjustment. RESULTS The principal outcome measure time to all-cause discontinuation indicated superiority for monotherapy over polypharmacy for the majority of (oral and depot) second generation APs (SGAs). For first generation APs (FGAs), oral formulations did not show a difference between monotherapy and polypharmacy, while depot formulations exhibited polypharmacy advantage. For the four most frequently used oral SGAs, the median times to all-cause discontinuation for monotherapy and polypharmacy, respectively, were 192 and 100 days for aripiprazole; 222 and 86 days for olanzapine; 176 and 91 days for quetiapine; and 157 and 93 days for risperidone. For mortality and hospitalization, a significant overall advantage of polypharmacy was detected. CONCLUSIONS Our study provides evidence for the superiority of monotherapy over polypharmacy for SGAs in terms of all-cause treatment discontinuation in schizophrenia. Polypharmacy, however, was associated with a lower likelihood of mortality and hospitalizations. The finding that MA is superior to PA for long-term sustained treatment whereas polypharmacy has advantage in mortality and psychiatric hospitalizations suggests that combination treatments may be more efficacious during exacerbation of psychotic symptoms.
