Schizophrenia is a severe mental disorder with various medical comorbidities and early mortality. Hyperprolactinemia is common in women and its impact on sexual function, galactorrhea and amenorrhea is well known. This paper evaluates the risk of 25-hydroxy vitamin D deficiency and other metabolic related laboratory abnormalities in women with schizophrenia having hyperprolactinemia (N = 43). The mean prolactin level in these women was 88.5 ± 56.0 ng/mL. We found that 100% of women were overweight of which 74% (32/43) of the women were obese, 56% (23/41) had abnormal total cholesterol levels and 30% (13/43) had high fasting blood glucose. Vitamin D levels were considered deficient or inadequate in 37% of women. We did not see significant correlations of prolactin with laboratory measures, however all female patients had elevated and high prolactin levels, leading to low variability in a small sample, which may have precluded seeing any direct relationships. Recognizing prolactin related side effects and understanding the role of other health measures seen in women with antipsychotic induced hyperprolactinemia in our female patients are critical steps toward better personalization of their care and recovery.

Schizophrenia is a serious mental illness that requires continuous and effective long-term management to reduce symptoms, improve quality of life, and prevent relapse. Oral antipsychotic medications have proven efficacy for many patients taking these medications; however, a considerable number of patients continue to experience ongoing symptoms and relapse, often due to lack of adherence. The advent of long-acting injectable (LAI) formulations of antipsychotic medications provided an opportunity to improve treatment adherence and overall patient outcomes. Despite data to support LAI efficacy, safety, and improved adherence over oral formulations, there are several misconceptions about and barriers to LAI implementation within a standard of care for patients with schizophrenia. Areas of resistance around LAIs include (1) doubts regarding their benefits outside of improved adherence, (2) questions regarding their prescribing to a broader population of patients with schizophrenia, (3) when to initiate LAIs, (4) concerns regarding the safety of LAIs in comparison with oral medication, and (5) the most effective ways to educate healthcare providers, patients, and caretakers to enable appropriate LAI consideration and acceptance. Here, we discuss these key controversies associated with LAIs and provide supportive evidence to facilitate LAI use in a manner that is constructive to the clinician–patient relationship and successful treatment., Plain Language Summary Schizophrenia is a mental condition that affects how a person acts, thinks, sees, and interprets their surroundings and expresses how they feel. Relapse can lead to hospitalization and other poor outcomes. Almost half of patients with schizophrenia tend to start and stop treatment, which can cause more relapses and make symptoms worse over time. Using antipsychotic drugs long term can reduce impairing illness symptoms and improve patient quality of life. Consistent use of antipsychotic drugs can help prevent relapse. Available antipsychotic drugs can be taken by mouth (oral) or by an injection. Oral drugs have to be taken every day, whereas long-acting injections (LAIs) of antipsychotic drugs can be given less often, such as every 2 weeks, monthly, and up to once every 3 months. In the past, LAIs were used only when oral antipsychotic drugs did not work, which was usually because patients did not take them every day. However, LAIs also work as an early treatment, which can be better for the patient. Patients taking LAIs skip fewer doses and so may have fewer relapses and hospitalizations. Because LAIs have to be given at the clinic, patients get more regular medical care and tend to keep taking their medicine for longer. Most LAI side effects are similar to those of oral antipsychotic drugs. Despite this, some clinicians hesitate to prescribe LAIs. More education for clinicians and patients about LAIs could increase interest and use. Recovery and relapse prevention are the main treatment goals for patients and their care team, and LAIs can improve both.

Background This post hoc analysis of clinical trial data evaluated long-term, self-reported mental and physical health-related quality of life (HRQoL) scores in schizophrenia patients receiving aripiprazole lauroxil (AL), an atypical long-acting injectable (LAI) antipsychotic approved for the treatment of schizophrenia in adults. Methods The study population included 291 stable schizophrenia outpatients enrolled in 2 consecutive long-term safety studies of AL given every 4 weeks for up to 124 weeks. HRQoL was measured using the SF-36v2® Health Survey (SF-36v2) over the course of the follow-up. The primary outcome was change in SF-36v2 mental component summary (MCS) and physical component summary (PCS) scores from baseline to 124 weeks. To contextualize these scores, descriptive analyses were conducted to compare the scores with available scores for the general population as well as for other populations with chronic medical (ie, hypertension and type 2 diabetes) or psychiatric (ie, depression) conditions. Results Results from this post hoc analysis indicated that the mean MCS score for patients continuing AL improved significantly from baseline over 124 weeks (P Conclusions In this post hoc analysis, outpatients with schizophrenia who continued the LAI antipsychotic AL showed gradual and sustained improvement in self-reported mental HRQoL over several years of follow-up, whereas self-reported physical HRQoL did not change. By the end of follow-up, mental health scores of study patients with schizophrenia were comparable to those of the general population and better than those of patients with depression.

Olanzapine is a second-generation atypical antipsychotic with proven efficacy for the treatment of schizophrenia. Approved in 1996, olanzapine is one of the most studied antipsychotics, resulting in a considerable amount of clinical data across diverse patient populations. Despite the fact that olanzapine is associated with a known risk of metabolic side effects, including weight gain, many clinicians continue to prescribe olanzapine for the treatment of schizophrenia with the expectation of additional therapeutic antipsychotic efficacy relative to other first-line atypical antipsychotics. The goal of this narrative is to revisit the role of oral olanzapine in the management of patients with schizophrenia, including those with recently diagnosed schizophrenia ("first-episode"), those with an established schizophrenia diagnosis who experience acute exacerbations, those receiving long-term antipsychotic treatment as a maintenance intervention, and those with suboptimal response to antipsychotic treatment, including treatment resistance. Collectively, data from published literature support the favorable efficacy of olanzapine compared with other first- and second-generation antipsychotics, including lower rates of treatment discontinuation and clinically meaningful improvements in the symptoms of schizophrenia. The development of antipsychotic medications with the favorable efficacy of olanzapine, but with reduced weight gain, could address a major unmet need in the treatment of schizophrenia.

Purpose Tardive dyskinesia (TD) is a common but serious hyperkinetic movement disorder and side effect of antipsychotic medications used to treat bipolar disorder (BD), major depressive disorder (MDD), and schizophrenia (SZ). The purpose of this study was to evaluate health-related quality of life (HRQoL) in a population with diagnoses for BD, MDD, or SZ by comparing patients with TD (n = 197) with those without TD (n = 219). HRQoL in each group was also compared with HRQoL of the general population. Methods This study employed a cross-sectional web-based survey. HRQoL was assessed by four instruments: the SF-12 Health Survey, Version 2 (SF-12v2), the Quality of Life Enjoyment and Satisfaction Questionnaire, Short Form (Q-LES-Q-SF), the Social Withdrawal subscale of the Internalized Stigma of Mental Illness Scale (SW-ISMI); and two questions on movement disorders. Results Patients with TD had significantly worse HRQoL and social withdrawal than those without. The differences were more pronounced for physical HRQoL domains than for mental health domains. Patients with more-severe TD, assessed through either self-rating or clinician rating, experienced significantly worse HRQoL than did those with less-severe TD. The impact of TD was substantially greater in patients with SZ than in those with BD or MDD. Compared with the general population, patients with BD, MDD, or SZ experienced significantly worse HRQoL regardless of TD status, although this deficit in HRQoL was greater among those with TD. Conclusions The presence of TD is associated with worse HRQoL and social withdrawal. The most severe impact of TD is on physical aspects of patients’ HRQoL.

The metabolic syndrome is highly prevalent in patients with schizophrenia. We previously found that blood C-reactive protein (CRP), interleukin-6 (IL-6), and leptin levels were predictors of current metabolic syndrome in schizophrenia. In the present study, we investigated whether baseline levels of total and differential white blood cell (WBC) counts, inflammatory markers, and adipokines predicted incident metabolic syndrome in schizophrenia.For subjects from the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) schizophrenia trial who did not have metabolic syndrome at baseline (n = 726), WBC counts, inflammatory markers, and adipokines were investigated as predictors of incident metabolic syndrome over 12 months of antipsychotic treatment. Cox proportional hazards regression models, controlling for multiple potential confounding factors, were used to investigate these associations.39% of subjects (n = 280) had incident metabolic syndrome over 12 months. After controlling for potential confounders, baseline blood IL-6 (HR = 1.12, 95% CI 1.01-1.24, p = 0.031) and leptin (HR = 1.12, 95% CI 1.01-1.24, p = 0.038) were significant predictors of incident metabolic syndrome, and there was a trend-level association with CRP (HR = 1.09, 95% CI 1.00-1.19, p = 0.059).Our findings provide additional evidence that measurement of inflammatory markers and adipokines are germane to the clinical care of patients with schizophrenia. Specifically, these markers may identify-prior to treatment-patients with schizophrenia at heightened risk for incident adverse cardiometabolic effects of antipsychotics. Given the tremendous burden of cardiovascular disease morbidity and mortality in schizophrenia, vigilant screening for and treatment of metabolic risk factors in this patient population are warranted.

OBJECTIVE Clozapine use is associated with myocarditis. In this study, we investigated what clinical signs and symptoms, and/or laboratory test(s), alert clinicians to presumptive myocarditis (PrMy) most accurately and at the earliest time point. We also investigated the incidence of PrMy during the initial exposure to clozapine versus in patients restarted on clozapine after extended interruption of prior prolonged treatment. METHODS 100 patients admitted to state psychiatric hospital started on clozapine were recruited into the study. 76 patients were treated with clozapine for the first time and 24 patients were restarts. Creatine kinase (CK), troponin I (TROP), eosinophil count (EOS), and C-reactive protein (CRP) were obtained at baseline and weeks 1, 2, 3, and 4. Descriptive statistics were calculated for demographic and clinical variables. Student's t test and chi-squared test were used to compare means and proportions between initial exposure and restart groups. RESULTS Clinical features and laboratory tests suggestive of PrMy were seen in 4 patients (5.3%) in initial exposure group and none in restart group. 3.5% of TROP levels were abnormal in initial exposure group and no abnormal levels were found in the restart group. 30% and 46% of CK, 23% and 39% of CRP, and 14% and 23% of EOS were abnormal in initial exposure group and restart groups, respectively. CONCLUSIONS PrMy was common (5.3%) during clozapine initiation. Prospective management through serial laboratory monitoring with weekly TROP levels was sensitive enough to allow for timely clozapine discontinuation.

Objective: Insomnia occurs frequently in the clinical course of schizophrenia. There is a robust association between insomnia and suicide in other psychiatric disorders. Several previous studies found associations between insomnia and suicidal ideation, suicide attempt, and psychopathology in schizophrenia. We explored these associations in a cross-sectional study of a large sample of patients with schizophrenia. Methods: In February 2020, we investigated relationships between current insomnia, suicidal ideation over the past 2 weeks, suicide attempt in the past 6 months (assessed by either the Calgary Depression Scale for Schizophrenia or self-report), and current psychopathology for subjects with baseline data from the Clinical Antipsychotic Trials of Intervention Effectiveness (DSM-IV schizophrenia trial conducted 2001-2004) using regression models. Results: After controlling for multiple potential confounding factors, terminal insomnia was associated with significant, 2.7-fold increased odds of current suicidal ideation (OR = 2.7, 95% CI = 2.0-3.6, P

Patients taking dopamine-blocking agents such as antipsychotics are at risk for developing tardive dyskinesia. In this webcast, Drs McEvoy and Nierenberg discuss symptoms of tardive dyskinesia, how to observe patients (whether in person or via telemedicine), and how to educate patients and families about TD.

​​​​​​ Clinicians now have 2 effective and well-tolerated vesicular monoamine transporter 2 (VMAT2) inhibitors-valbenazine and deutetrabenazine-for the treatment of patients with tardive dyskinesia (TD), a severe and potentially irreversible side effect associated with dopamine receptor blocking agents. Clinicians should use measurement-based care, eg, the Abnormal Involuntary Movement Scale with activation maneuvers, to assess and document TD symptoms and treatment progress. Each follow-up visit should be personalized with questions related to patients' functioning and level of distress regarding their specific TD symptoms. Family members, if available, can provide information on symptom changes and assistance with medication adherence. With continued treatment and measurement-based care, patients can experience improvement in their TD symptoms.

BackgroundSuicide risk among individuals with schizophrenia (SZ) is intractably high, with over 40% of individuals attempting to take their own lives during their lifetime and an estimated 5–10% completing suicide. At present, available pharmacological and psychotherapeutic treatments offer limited risk reduction benefits, and thus, there remains an urgent need to explore novel interventions that will ameliorate this risk. Aerobic exercise (AE) has been shown to improve a number of predictors of suicide risk (e.g., depressed mood, sleeping difficulties). As individuals with SZ display a highly sedentary lifestyle, AE may reduce suicide risk.MethodsEmploying a multi-site, single-blind, randomized clinical trial design, we will examine the impact of AE on risk for suicide and related variables in individuals with SZ. Participants will be randomized to one of two 12-week exercise interventions: AE or a stretching and toning (ST) control intervention. Primary outcome measures will include suicide risk (Columbia Suicide Severity Rating Scale, C-SSRS) and aerobic fitness (VO2max), along with additional measures of suicide risk, mood, emotion regulation, sleep, cognition, and physical activity, with assessments completed at baseline and after 6 and 12 weeks of interventions.DiscussionIt is hypothesized that AE will reduce suicide risk among individuals with SZ. This study may offer support for a more efficacious treatment method for this population in addition to the pre-existing pharmacological and psychotherapeutic treatment regimens.Trial registrationClinicaltrials.gov,NCT03270098.

​​ Tardive dyskinesia (TD) is a condition of potentially irreversible abnormal involuntary movements associated with dopamine receptor blocking agents, such as antipsychotics. While prevention is the best strategy, it is not always possible. This report outlines strategies to reduce TD symptoms, including the use of the FDA-approved treatment options (valbenazine and deutetrabenazine).

Objective To determine if a single baseline adherence assessment (Brief Adherence Rating Scale [BARS]) could identify patients who are likely to respond to long-acting injectable (LAI) antipsychotic treatment. Method The current secondary analysis included a sub-sample of adult outpatients (N = 176) with schizophrenia or schizoaffective disorder who participated in the “A Comparison of Long-Acting Injectable Medications for Schizophrenia (ACLAIMS)” trial and had a baseline BARS assessment and a baseline and month 3 Positive and Negative Syndrome Scale (PANSS) rating. The main outcome was LAI treatment response, defined as a ≥ 20% decrease (baseline to month 3) on the PANSS total score. Receiver Operating Characteristic (ROC) and Area Under the Curve (AUC) analysis was conducted to determine the optimal cutpoint of baseline BARS adherence in discriminating LAI treatment response at month 3. A logistic mixed model estimated the odds of response to LAI treatment at month 3 from the optimal baseline BARS cutpoint. Results The ROC analysis determined that the single baseline BARS rating (cutoff ≤66%), indicating low adherence, best discriminated patients likely to respond to LAI treatment (AUC = 0.603, SE = 0.046, 95% binomial exact CI = 0.527 to 0.676, p = 0.025), with 38% sensitivity and 85% specificity. The logistic mixed model analysis revealed that patients with ≤66% BARS adherence had 3.464 times the predicted odds (95% CI = 1.604 to 7.480, p = 0.001) of responding to LAI treatment than those who were >66% BARS adherent. Conclusion A single baseline BARS assessment discriminated response to LAI treatment suggesting it is a reasonable tool to identify candidates for LAI antipsychotic treatment.

In schizophrenia, the years before psychosis are morbid, not premorbid. Widespread, low-grade corruption of circuitry (brain damage) occurs, resulting in enduring deficits in cognitive, social, and motor functioning and motivation. These deficits persist during patients’ lifetime and do not respond to medication or talking. Expectations of patients’ functioning must be modified (reduced); interactions and environments must be accommodated to support best residual functioning, and prostheses (mechanical or actions of others) must replace functions no longer available. One of the deficits—anosognosia—interferes with treatment efforts. When the circuits managing dopamine neurons in the ventral tegmental area are corrupted, storms of dopamine imbue random items of sensory experience and intrapsychic life with salience—psychosis appears. Early and uninterrupted dopamine antagonist medication results in sustained remission of psychosis but is rarely achieved because of the inadequacies of standard care. Enduring engagement by multi-disciplinary teams is the necessary response to the neurobiology of schizophrenia.

Schizophrenia is associated with abnormal levels of blood inflammatory markers, which may be correlated with levels of psychopathology. Few previous studies have explored whether baseline inflammatory marker levels predict longitudinal changes in psychopathology. In the present study, we explored this association in a cohort of patients with schizophrenia.We investigated inflammatory markers and psychopathology after 3, 6, and 12 months of antipsychotic treatment for subjects with baseline and follow-up data from the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) schizophrenia trial. Linear regression models, controlling for multiple potential confounding factors, were used to investigate these associations.There was a significant decrease in monocyte, ICAM, and adiponectin levels between baseline and 12 months. Higher baseline blood interleukin-6 (IL-6) predicted greater reduction in PANSS total and general subscale scores at 3 and 6 months, and PANSS negative subscale scores at 3 months (β = -0.10 to -0.16, p 0.05 for each). Higher baseline blood leptin levels predicted greater reduction in PANSS total, negative and general subscale scores at 6 months (β = -0.09 to -0.11, p 0.05 for each). In post-hoc analyses, associations between baseline IL-6 levels and symptom reduction were strongest in patients treated with either ziprasidone or quetiapine. Changes in blood inflammatory markers were generally not associated with changes in psychopathology.Our findings provide additional support that measuring blood inflammatory markers may be relevant to the clinical care of patients with schizophrenia. Specifically, these markers may help guide selection of antipsychotic treatment towards more personalized medicine approaches for patients with schizophrenia.

Prolactin-related adverse effects contribute to nonadherence and adverse health consequences, particularly in women with severe mental illness. Treating these adverse effects may improve treatment acceptability, adherence, and long-term outcomes.Premenopausal women with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision diagnosis of schizophrenia, schizoaffective disorder, or bipolar disorder were recruited for a randomized, double-blind, placebo-controlled 16-week trial of adjunct aripiprazole (5-15 mg/d). Participants had elevated prolactin (24 ng/mL) and were experiencing galactorrhea, amenorrhea, oligomenorrhea, or sexual dysfunction on a prolactin-elevating antipsychotic. Participants were evaluated biweekly for prolactin elevation and galactorrhea and completed a menstrual diary review. Psychiatric symptoms and adverse effects were closely monitored.Forty-six women were randomized (n = 25 aripiprazole, n = 21 placebo). Thirty-seven completed at least 8 weeks of the study (n = 20 [80%] aripiprazole and n = 17 [81%] placebo). Aripiprazole (mean dose, 11.7 ± 2.4 mg/d) was effective for lowering prolactin relative to placebo (P = 0.04). In addition, 45% (9/20) of the aripiprazole group had a normalized prolactin (24 mg/mL) compared with 12% (2/17) of the placebo group (P = 0.028). Galactorrhea resolved in 77% (10/13) of the aripiprazole-treated participants compared with 33% (4/12) in the placebo group (P = 0.028). Normalization of sexual function (16 on the Arizona Sexual Experience Scale) occurred in 50% on aripiprazole (7/14) versus 9% (1/11) on placebo (P = 0.030). No differences between groups in symptoms or adverse effects were noted. Overall, women rated a mean score of 4.6 ± 0.6 on a 5-point Likert scale for sexual function improvement, suggesting their particular satisfaction with improvement in this domain.Building upon prior studies, this rigorous evaluation confirms the utility of adjunctive aripiprazole as a strategy for improving prolactin and managing prolactin-related adverse effects in premenopausal women with psychosis.

Insomnia and inflammation are both common in schizophrenia. In the general population, insomnia is associated with inflammation. In n=519 subjects from the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) schizophrenia trial, terminal insomnia was investigated as an indicator of inflammation using non-parametric ANCOVA. After controlling for potential confounders, insomnia was significantly associated with higher blood IL-6 (F=4.12, p=0.007) and leptin (F=9.67, p0.001) with large effect sizes (d=1.03 and d=0.79, respectively). Findings suggest that the assessment of insomnia is relevant to studies of inflammation in schizophrenia, and germane to trials of adjunctive hypnotics and anti-inflammatory agents in these patients.

OBJECTIVE To evaluate durability of therapeutic effect of long-term treatment with aripiprazole lauroxil in patients with schizophrenia following successful treatment of an acute psychotic episode. METHODS This post hoc analysis assessed long-term outcomes for a subgroup of patients who entered a 52-week extension study after being successfully stabilized with one of 2 doses of aripiprazole lauroxil (441 or 882 mg) in a pivotal 12-week, placebo-controlled, randomized clinical trial. Durability of therapeutic effect was measured by the proportion of patients completing the 1-year course of aripiprazole lauroxil, the trajectories of the Positive and Negative Syndrome Scale (PANSS) total and the Clinical Global Impression-Severity (CGI-S) item scores beyond the first 12 weeks, and the likelihood of remission at any follow-up point. RESULTS In total, 181 patients treated with aripiprazole lauroxil entered the extension study; 73% and 66% of patients from the 441 mg and 882 mg groups, respectively, completed all 13 aripiprazole lauroxil treatments scheduled every 4 weeks over 52 weeks. Both groups continued on a positive trajectory of symptom improvements (P < .0001 for reductions in PANSS total and CGI-S scores from week 12 to end of follow-up). Most patients (74% and 68% in the aripiprazole lauroxil 441 mg and 882 mg groups, respectively) achieved remission during follow-up. CONCLUSIONS These post hoc analyses of a subgroup of patients demonstrate the continued therapeutic efficacy of aripiprazole lauroxil after successful treatment of an acute episode of schizophrenia. Both the 441 mg and 882 mg groups had similar retention rates, degree of symptom improvement, and likelihood of remission.

Summary Background Tardive dyskinesia results from exposure to dopamine receptor antagonists, such as typical and atypical antipsychotics. If clinically appropriate, clinicians often manage this disorder by lowering the dose of, or discontinuing, the causative drug. There is a significant unmet need for a treatment option that does not disrupt treatment regimens for underlying psychiatric illnesses. We aimed to assess the efficacy, safety, and tolerability of fixed doses of deutetrabenazine—a novel vesicular monoamine transporter-2 inhibitor—in patients with tardive dyskinesia. Methods We did this double-blind, randomised, placebo-controlled, phase 3 trial at 75 centres in the USA and Europe. Patients aged 18–80 years with tardive dyskinesia (≥3 months before screening) were randomly assigned centrally (1:1:1:1), via interactive response technology, to receive one of three fixed doses of deutetrabenazine (12 mg/day, 24 mg/day, or 36 mg/day) or matching placebo. Randomisation was stratified by baseline use of dopamine receptor antagonists. Patients were started on oral deutetrabenazine 12 mg/day, and this dose was increased through week 4 until the randomised dose was achieved, then maintained over 8 weeks. During the treatment period, patients, investigators, their site personnel, and sponsor were masked to group assignment. The primary efficacy endpoint was change in Abnormal Involuntary Movement Scale (AIMS) score from baseline to week 12 in patients with at least one post-baseline rating. The primary efficacy analysis was done in the modified intention-to-treat population (baseline AIMS score ≥6 and at least one post-baseline rating). The safety analysis was done in patients who received any study drug. This trial is registered with ClinicalTrials.gov, number NCT02291861. Findings Between Oct 29, 2014, and Aug 19, 2016, we randomly assigned 298 patients to receive at least one dose of placebo (n=74), deutetrabenazine 12 mg/day (n=75), 24 mg/day (n=74), or 36 mg/day (n=75); 222 patients comprised the modified intention-to-treat population and 293 patients comprised the safety population. From baseline to week 12, the least-squares mean AIMS score improved by −3·3 points (SE 0·42) in the deutetrabenazine 36 mg/day group, −3·2 points (0·45) in the 24 mg/day group, and −2·1 points (0·42) in the 12 mg/day group, with a treatment difference of −1·9 points (SE 0·58, 95% CI −3·09 to −0·79; p=0·001), −1·8 points (0·60, −3·00 to −0·63; p=0·003), and −0·7 points (0·57, −1·84 to 0·42; p=0·217), respectively, versus −1·4 points (0·41) in the placebo group. The rate of adverse events was similar between patients in the deutetrabenazine 36 mg/day group (n=38/74 [51%]), 24 mg/day group (n=32/73 [44%]), and 12 mg/day group (n=36/74 [49%]), and those in the placebo group (n=34/72 [47%]). Serious adverse events were reported in four (5%) patients given deutetrabenazine 36 mg/day, six (8%) patients given 24 mg/day, and two (3%) patients given 12 mg/day, compared with four (6%) patients given placebo. Two (1%) patients in the safety population died, one each in the deutetrabenazine 24 mg/day and 36 mg/day groups; neither death was deemed related to study drug by the investigator or sponsor. Interpretation Deutetrabenazine 24 mg/day and 36 mg/day provided a significant reduction in tardive dyskinesia, with favourable safety and tolerability. These findings suggest that dosing regimens could be individualised and tailored for patients on the basis of dyskinesia control and tolerability. Funding Teva Pharmaceutical Industries.

Clozapine is the sole antipsychotic agent effective for the treatment of refractory schizophrenia. Sixty percent of clozapine-treated patients, however, fail to adequately respond. Minocycline, a tetracycline antibiotic, possesses antiinflammatory and neuroprotective properties that may play a role in schizophrenia. Clozapine is mainly metabolized by CYP1A2 enzymes, and minocycline may potentially inhibit CYP1A2 as hypothesized by case report data. To date, no pharmacokinetic interaction has been reported between minocycline and clozapine. This is a secondary analysis of a 10-week controlled study of adjunctive minocycline to clozapine in treatment refractory schizophrenia. Clozapine plasma levels were collected every two weeks during the study. 28 participants assigned to receive minocycline and 22 assigned to placebo were included. No differences existed in baseline demographics, clozapine dose or plasma levels. Average changes from baseline in clozapine plasma level (p = 0.033) were significantly higher in the minocycline group despite maintenance of stable doses. No statistically significant treatment differences were found in the norclozapine (p = 0.754) or total clozapine (p = 0.053) changes in plasma levels, although possible changes in total clozapine levels require further investigation. This analysis suggests that minocycline administration may lead to increased clozapine plasma levels. Further study is needed to examine possible explanations.

Tardive dyskinesia (TD), a condition characterized by involuntary movements, is found in patients taking antipsychotics or other agents that block dopamine receptors. Symptoms of TD are associated with reduced quality of life, psychosocial problems, and medication nonadherence. Few agents tested in the treatment of TD had sufficient data to support or refute their use, until recently. A review of new evidence was combined with the existing guideline to provide new treatment recommendations. This activity provides an overview of treatments for patients with TD, including valbenazine and deutetrabenazine, which both received FDA approval for the treatment of TD.

Dopamine receptor blocking agents-including antipsychotics-can produce tardive dyskinesia (TD). First-generation antipsychotics were effective in treating schizophrenia and severe forms of bipolar disorder; however, they were associated with substantial extrapyramidal effects, especially at high doses. Second-generation antipsychotics are effective and produce fewer adverse movement effects; nevertheless, the risk for TD was not eliminated. Tardive dyskinesia can be distressing to patients with good insight into their illness and the movements, especially if they are working and in relationships, and should be treated to improve psychosocial outcomes. In patients with poor insight into their illness and lack of awareness of their TD symptoms, clinicians should treat TD if it causes severe impairment.

Schizophrenia is associated with an increased prevalence of infections throughout the life span. Previous studies have found an association between urinary tract infection (UTI) and acute psychosis. We investigated the prevalence and correlates of UTI in a large cohort of patients with schizophrenia.We estimated the prevalence of UTI at the baseline visit of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) schizophrenia trial. We then investigated associations between UTI and inflammatory markers, psychopathology, and cognition, controlling for potential confounding factors.The prevalence of probable UTI at baseline in the CATIE trial was 1.2% (n = 13 of 1,061 participants). Compared with participants with a normal urinalysis (n = 387), after controlling for potential confounders, UTI was a significant predictor of greater impairments (approximately 1 standard deviation difference) in the cognition composite score (beta = -0.153, P = .002), and poorer working memory (beta = -0.190, P.001). There were no differences in psychopathology scores between participants with probable UTI and those with a normal urinalysis.Urinary tract infections in patients with schizophrenia may have an impact on cognition. Findings provide additional evidence regarding infectious disease comorbidity, which may be clinically relevant in the treatment of patients with schizophrenia.

Objective A nominal group process followed by a modified Delphi method was used to survey expert opinions on best practices for tardive dyskinesia (TD) screening, diagnosis, and treatment and to identify areas lacking in clinical evidence. Participants A steering committee of 11 TD experts met in nominal group format to prioritize questions to be addressed and identify core bibliographic materials and criteria for survey panelists. Of 60 invited experts, 29 (23 psychiatrists and 6 neurologists) agreed to participate. Evidence A targeted literature search of PubMed (search term: tardive dyskinesia) and recommendations of the steering committee were used to generate core bibliographic material. Inclusion criteria were as follows: (1) review articles, meta-analyses, guidelines, or clinical trials; (2) publication in English between 2007 and 2017; (3) > 3 pages in length; and (4) publication in key clinical journals with impact factors ≥ 2.0. Of 29 references that met these criteria, 18 achieved a score ≥ 5 (calculated as the number of steering committee votes multiplied by journal impact factor and number of citations divided by years since publication) and were included. Consensus process Two survey rounds were conducted anonymously through electronic media from November 2017 to January 2018; responses were collected, collated, and analyzed. Respondent agreement was defined a priori as unanimous (100%), consensus (75%-99%), or majority (50%-74%). For questions using a 5-point Likert scale, agreement was based on percentage of respondents choosing ≥ 4 ("agree completely" or "agree"). Round 1 survey included questions on TD screening, diagnosis, and treatment. Round 2 questions were refined per panelist feedback and excluded Round 1 questions with 75% agreement (unless feedback suggested further investigation). Conclusions Consensus was reached that (1) a brief, clinical assessment for TD should be performed at every clinical encounter in patients taking antipsychotics; (2) even mild movements in 1 body area may represent possible TD; (3) management requires an overall evaluation of treatment, including reassessment of antipsychotics and anticholinergics as well as consideration of vesicular monoamine transporter 2 (VMAT2) inhibitors; and (4) informed discussions with patients/caregivers are essential.

BACKGROUND: Women with serious mental illnesses like bipolar disorder and schizophrenia are more likely to be tobacco smokers as compared to women without mental illness. Antipsychotic medications may impact craving and nicotine’s rewarding effects via dopaminergic neurotransmitter activity. Differences in pharmacologic profiles and receptor affinity among antipsychotic agents may lead to variability in impact on craving and/or substance use. Aripiprazole, a partial dopamine agonist antipsychotic, may impact tobacco craving. To our knowledge, no one has specifically examined tobacco craving/usage patterns in women with psychotic disorders treated with adjunctive aripiprazole. METHODS: We report baseline and endpoint tobacco use/craving data for cigarette smokers completing a 16-week randomized double-blind placebo-controlled trial of adjunct aripiprazole vs placebo. Participants recruited were all women with high prolactin levels and not reporting any desire to change smoking behaviors, which provides the opportunity to look at a naturalistic population. Assessments included the Fagerstrom Test for Nicotine Dependence (FTND) Scale, the Tobacco Craving Questionnaire-Short Form (TCQ-SF), the Drug and Alcohol Use Summary, expired carbon monoxide (CO), and all answered questions about smoking habits at baseline, 8 weeks, and 16 weeks (endpoint). Between-group changes from baseline to endpoint were measured by Effect size (Cohen’s D) due to the underpowered pilot nature of the data. RESULTS: Of the 16 women smokers included, 9 were assigned to aripiprazole and 7 to placebo. The average age of participants was 38.5 years (SD=9.9) and mean age at onset of illness was 20.9 (SD=8). The average number of cigarettes smoked daily was 10.6 (SD=7.6) and the average years of smoking was 20.9 (SD=10.4). Of the 16 participants, 2 (12.5%) were diagnosed with bipolar disorder, 4 (25%) had schizoaffective disorder, and 10 (62.5%) had schizophrenia. There were no baseline differences in demographic or smoking measures between groups. During the 16-week study the FTND scores were moderately decreased with aripiprazole relative to placebo with an effect size (ES) of -0.49. The ES for expired CO favoring aripiprazole was -0.86, however there wasn’t a decrease in the aripiprazole group, only an increase noted in the study with placebo. Aripiprazole, compared to placebo, did not appear to affect the number of cigarettes smoked daily (ES= -0.22) or the TCQ-SF scores (ES= 0.20). DISCUSSION: This pilot study is the first to evaluate the effect of adjunct aripiprazole on measures of tobacco and use and craving in women smokers with psychotic disorders. In this small sample there were moderate effect size favoring adjunct aripiprazole on a decrease in dependency scores but not in craving and cigarette smoking. Future research should investigate the impact of aripiprazole on tobacco craving in a larger sample. Additionally, both men and women should be included for a representative sample and to examine potential sex differences. This study was funded by NIMH R01 (MH090071-04) (Kelly PI) and NIDA K23 (DA034034-01A1) (Wehring PI). Aripiprazole and matching placebo were supplied by Bristol-Myers Squibb/Otsuka.

Olanzapine is a second-generation atypical antipsychotic with proven efficacy for the treatment of schizophrenia. Approved in 1996, olanzapine is one of the most studied antipsychotics, resulting in a considerable amount of clinical data across diverse patient populations. Despite the fact that olanzapine is associated with a known risk of metabolic side effects, including weight gain, many clinicians continue to prescribe olanzapine for the treatment of schizophrenia with the expectation of additional therapeutic antipsychotic efficacy relative to other first-line atypical antipsychotics. The goal of this narrative is to revisit the role of oral olanzapine in the management of patients with schizophrenia, including those with recently diagnosed schizophrenia (“first-episode”), those with an established schizophrenia diagnosis who experience acute exacerbations, those receiving long-term antipsychotic treatment as a maintenance intervention, and those with suboptimal response to antipsychotic treatment, including treatment resistance. Collectively, data from published literature support the favorable efficacy of olanzapine compared with other first- and second-generation antipsychotics, including lower rates of treatment discontinuation and clinically meaningful improvements in the symptoms of schizophrenia. The development of antipsychotic medications with the favorable efficacy of olanzapine, but with reduced weight gain, could address a major unmet need in the treatment of schizophrenia.

Individuals with schizophrenia (SZ) display cognitive deficits that have been identified as major determinants of poor functioning and disability, representing a serious public health concern and an important target for interventions. At present, available treatments offer only minimal to moderate benefits to ameliorate cognitive deficits. Thus, there remains an urgent need to identify novel interventions to improve cognition in people with SZ. Emerging evidence from animal and basic human research suggests aerobic exercise training (AE) has beneficial effects on cognition. Preliminary findings suggest that AE is efficacious in improving cognitive functioning in SZ, however the extant studies have been limited by small samples, a dearth of information on biologically-relevant covariates, and limited information on impact on daily functioning. Additionally, while AE-related cognitive benefits have been linked to Brain-Derived Neurotrophic Factor (BDNF) upregulation, this putative mechanism needs confirmation. The present report describes a study protocol designed to address these limitations—we review and summarize the current literature on treatment of cognitive deficits in SZ, state the rationale for employing AE to target these deficits, and describe the current protocol—a multi-site, single-blind, randomized clinical trial aiming to recruit 200 community-dwelling individuals with SZ. Participants are randomized to one of two 12-week interventions: AE using active-play video games (i.e., Xbox Kinect) and traditional cardiovascular exercise equipment or a stretching-and-toning (ST) control intervention. Participants undergo assessments of aerobic fitness, cognition, and daily functioning, as well as BDNF and other biomarkers of cognitive change, at baseline and after 6- and 12-weeks.

Clozapine is a highly effective antipsychotic medication, which provides a range of significant benefits for patients with schizophrenia, and is the standard of care for treatment-resistant schizophrenia as well as for reducing the risk of suicidal behaviors in schizophrenia and schizoaffective disorder. However, clozapine is widely underutilized, largely because prescribing clinicians lack experience in prescribing it and managing its adverse events (AEs). Clozapine is associated with three uncommon but immediately dangerous AEs-agranulocytosis, myocarditis/cardiomyopathy, and seizures-as well as AEs that may become dangerous if neglected, including weight gain, metabolic syndrome and constipation, and others that are annoying or distressing such as sedation, nighttime enuresis and hypersalivation. Because of the risk of agranulocytosis, clozapine formulations are available only through restricted distribution via a patient registry, with mandatory, systematized monitoring for absolute neutrophil count using a specific algorithm. We identified articles on managing clozapine-associated AEs by searching PubMed using appropriate key words and search techniques for each topic. A review of the prevalence and clinical characteristics of clozapine-associated AEs shows that these risks can be managed efficiently and effectively. The absolute risks for both agranulocytosis and myocarditis/cardiomyopathy are low, diminish after the first six months, and are further reduced with appropriate monitoring. Weight gain/metabolic disorders and constipation, which develop more gradually, can be mitigated with regular monitoring and timely interventions. Sedation, hypersalivation, and enuresis are common but manageable with ameliorative measures and/or medications.

In this study, we examined if a self-report of trait spite, the Spitefulness Scale, retains the same associations with dark personality traits in individuals with severe mental illness. We also examine if reports on the Spitefulness Scale are correlated with observed spiteful behavior in a game developed to offer opportunities for spite. One hundred twenty individuals clinically diagnosed with psychotic spectrum disorders and receiving inpatient treatment at a state hospital participated in this study and completed measures of personality. The Spitefulness Scale retained its associations with measures of dark personality traits in individuals with psychosis. Spitefulness Scale scores were also related to a performance measure of spite and spite was evidenced by a significant proportion of participants across measures (20.8%-26.7%). These data suggest the presence of spite as it is understood in the general population in a significant subset of individuals with psychosis. Spite could be considered an independent personality trait and part of the family of dark personality traits.

Brexpiprazole is an antipsychotic medication and received approval by the U.S. Food and Drug Administration for the treatment of schizophrenia in July 2015. Brexpiprazole acts as a partial agonist at dopamine D2 and serotonin 5-HT1A receptors, and as an antagonist at serotonin 5-HT2A and at adrenergic alpha1B and alpha2C receptors. Compared with aripiprazole, brexpiprazole is more potent at 5-HT1A receptors and displays less intrinsic activity at D2 receptors. The recommended dose range of brexpiprazole for the treatment of schizophrenia is 2-4 mg/day; the recommended titration schedule is to start with 1 mg/day and increase to 2 mg/day on Day 5 to Day 7, then to 4 mg/day on Day 8. Two positive, 6-week, Phase 3 randomized controlled trials in acute schizophrenia demonstrated superiority of brexpiprazole over placebo. Pooled responder rates were 46% for brexpiprazole 2-4 mg/day vs. 31% for placebo, resulting in a number needed to treat (NNT) of 7. In a 52-week, randomized withdrawal study, significantly fewer patients relapsed in the brexpiprazole group compared with placebo (13.5% vs. 38.5%), resulting in an NNT of 4. The most commonly encountered adverse event (incidence ≥4% and at least twice the rate of placebo) is increased weight. Short-term weight gain appears modest (approximately 10% of patients receiving brexpiprazole 1-4 mg/day gained ≥7% body weight from baseline, compared with 4% for those randomized to placebo, resulting in a number needed to harm [NNH] of 17); however, more outliers with an increase of ≥7% of body weight were evident in open-label, 52-week safety studies. Effects on glucose and lipids were small. Rates of akathisia as an adverse event were 5.5% for the pooled doses of brexpiprazole 1-4 mg/day vs. 4.6% for placebo, yielding an NNH of 112. Minimal effects on prolactin were observed, and no clinically relevant effects on the ECG QTc interval were evident. Brexpiprazole is also approved as an adjunct medication for the treatment of major depressive disorder. Phase 3 trials are ongoing in patients with agitation associated with Alzheimer's disease.

Background In the KINECT 3 (NCT02274558; October 2014 to September 2015) study, valbenazine efficacy in tardive dyskinesia (TD) was demonstrated based on mean changes from baseline in the Abnormal Involuntary Movement Scale (AIMS) total score (sum of items 1-7). Data from this study were analyzed further to provide a more clinically meaningful interpretation of the primary AIMS results. Methods The study included adults who had a DSM-IV diagnosis of schizophrenia, schizoaffective disorder, or any mood disorder and also met DSM-IV criteria for neuroleptic-induced TD. Study participants received 6 weeks of double-blind treatment with valbenazine (40 or 80 mg/d) or placebo. Post hoc AIMS analyses, based on available data, included Cohen d effect sizes, response analyses with odds ratios (ORs) and numbers needed to treat (NNTs), and shift analyses. Results At week 6 (N = 202), medium-to-high effect sizes were found for mean improvements in AIMS total score (40 mg/d, d = 0.52; 80 mg/d, d = 0.89). For AIMS total score responses of ≥ 10% to ≥ 70% improvement from baseline, statistical significance was found for valbenazine 80 mg/d versus placebo (P ≤ .01), with ORs (range, 3.0-10.3) and NNTs (range, 3-9) indicating clinical relevance. For response per AIMS item (score ≤ 1 at week 6), significant differences between valbenazine (both doses or 80 mg/d) and placebo were found in the lips, jaw, tongue, and upper extremities. In participants who had an AIMS item score ≥ 1 at baseline, the percentage with a ≥ 1-point improvement at week 6 (shift) was significantly higher with valbenazine (40 and/or 80 mg/d) versus placebo in all 7 body regions. Conclusions Consistent with primary published results for KINECT 3, these supplemental analyses indicate that participants treated with valbenazine (40 or 80 mg/d) had statistically significant and clinically relevant improvements in TD severity both overall and in specific body regions.

OBJECTIVE: To investigate subgroup responses to long-acting injectable (LAI) haloperidol decanoate (HD) and paliperidone palmitate (PP) in a randomized controlled trial that found no difference between the treatments on the primary outcome of efficacy failure. METHOD: A Comparison of Long-Acting Injectable Medications for Schizophrenia (ACLAIMS) enrolled 311 participants from March 2011 to July 2013 meeting DSM-VI-TR criteria for diagnoses of schizophrenia or schizoaffective disorder at risk of relapse due to medication non-adherence or substance abuse. Participants were randomly assigned to double-blinded treatment with HD or PP and followed for up to 2 years. A committee blinded to treatment assignment adjudicated efficacy failure based on meeting at least one of these criteria: psychiatric hospitalization, crisis stabilization, increased outpatient visits, could not discontinue oral antipsychotic, discontinued assigned LAI due to inadequate therapeutic benefit, or prolonged need for adjunctive oral antipsychotic medication. Survival analyses examined modification of treatment effects on efficacy failure by age, gender, race, substance abuse, baseline symptom severity, and baseline adherence. Mixed effect linear models and analysis of covariance examined this modification on safety outcomes. RESULTS: An interaction between age and treatment (p=0.009) revealed younger participants assigned HD had longer time to efficacy failure than those assigned PP. Interactions were not significant between treatment group and gender, race, substance use disorder, baseline symptom severity, or baseline adherence. An interaction of treatment and age on akathisia (p=0.047) found an advantage for PP that was larger among younger persons. An advantage for HD on serum prolactin levels was larger among younger women (p=0.033). CONCLUSION: Among younger persons, HD was associated with lower rates of efficacy failure than PP. Age effects on adverse effects were mixed. Age-related heterogeneity of antipsychotic treatment effects warrants further investigation and consideration in clinical practice.

BackgroundTardive dyskinesia (TD) is an often-irreversible movement disorder that may intensify the stigma of patients with psychiatric disorders and worsen quality of life. In two randomized, double-blind, placebo (PBO)-controlled, 12-week trials, ARM-TD and AIM-TD (‘parent studies’), deutetrabenazine (DTB) demonstrated statistically significant improvements in centrally read Abnormal Involuntary Movement Scale (AIMS) scores at Week 12 compared with PBO and was generally well tolerated.Study ObjectiveTo evaluate the long-term efficacy of DTB in an open-label safety study following double-blind treatment using site-rated efficacy measures: AIMS, the Clinical Global Impression of Change (CGIC) and the Patient Global Impression of Change (PGIC), which may be used in real-world clinical practice settings.MethodPatients with TD who completed the parent studies were eligible to enter this open-label, long-term extension (OLE) after completing the 1-week washout period and final evaluation in the blinded portion of the trial. This extension comprised a 6-week titration period followed by a long-term maintenance phase. Patients began DTB at 12mg/day, titrating up to a maximum total dose of 48mg/day based on dyskinesia control and tolerability. Efficacy endpoints included in this analysis are the change in site-rated AIMS score (items 1–7) from parent study baseline, and the proportion of patients who were “Much Improved” or “Very Much Improved” (treatment success) on the CGIC and PGIC from OLE baseline.ResultsAt the end of the parent studies (Week 12), patients treated with DTB had experienced greater mean (standard error) improvements in site-rated AIMS score (–5.0[0.40]) than patients given PBO (–3.2[0.47]). With long-term DTB treatment, both groups experienced improvements in site-rated AIMS scores (prior DTB, –7.9[0.62]; prior placebo, –6.6[0.64]) compared with parent study baseline. Similarly, at the end of the parent studies, a greater proportion of patients treated with DTB had treatment success on the CGIC (DTB, 51%; PBO, 32%) and the PGIC (DTB, 46%; PBO: 33%); whereas at Week 54 of the OLE study, treatment success on CGIC and PGIC were similar in both the CGIC (prior DTB: 66%; prior PBO: 68%) and PGIC (prior DTB: 62%; prior PBO: 62%) groups. DTB was generally well tolerated.ConclusionsPatients treated with DTB showed improvements in abnormal movements, as measured by site-rated AIMS, CGIC, and PGIC scores, which may be used in real-world clinical practice settings. These results corroborate the previously reported efficacy of DTB as observed in the 12-week, double-blind ARM-TD and AIM-TD trials, in which central raters were used to evaluate AIMS scores.Presented at: American Psychiatric Association Annual Meeting; May 5–9, 2018, New York, New York, USAFunding Acknowledgements: Funding: This study was supported by Teva Pharmaceuticals, Petach Tikva, Israel.

The metabolic syndrome is highly prevalent in patients with schizophrenia, and is associated with a state of chronic, low-grade inflammation. We investigated relationships between total and differential white blood cell (WBC) counts, inflammatory markers, adipokines and the metabolic syndrome in patients with schizophrenia.For subjects with available data from the baseline/screening visit of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) schizophrenia trial, WBC counts, inflammatory markers, and adipokines were investigated as predictors of the metabolic syndrome (and its components), using linear and binary logistic regression models, controlling for potential confounding effects of age, sex, race, smoking, fasting status, alcohol, and illicit drug use.After controlling for potential confounders, blood CRP, interleukin-6, and leptin were significant predictors of all five individual components of the metabolic syndrome (as both continuous and categorical outcome measures). Furthermore, total WBC (OR=2.31, 95% CI 1.58-3.41, p0.01) and lymphocyte (OR=2.51, 95% CI 1.75-3.60, p0.01) counts were the strongest predictors of current metabolic syndrome.Our findings provide the strongest evidence to date that measurement of total and differential WBC counts are germane to the clinical care of patients with schizophrenia, and that inflammation and adipokines are associated with metabolic disturbance in these patients.

Schizophrenia has been associated with aberrant blood levels of inflammatory markers. However, patients with comorbid illicit drug use have been inadequately studied with respect to immune function. Furthermore, associations between inflammatory markers, psychopathology, and cognition have been inconsistently considered. We investigated relationships between inflammatory markers, comorbid marijuana and cocaine use, and psychopathology and cognition in patients with schizophrenia.For subjects with available fasting data from the baseline visit of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) schizophrenia trial, inflammatory markers were investigated as predictors of psychopathology and cognition in patients with and without comorbid marijuana or cocaine use, using linear regression models controlling for potential confounding factors.Compared to subjects with a negative urine drug screen (UDS), marijuana use was a predictor of higher lymphocytes and E-selectin, and lower leptin (p≤0.04 for each); cocaine use was a predictor of higher adiponectin (p=0.04). In subjects with marijuana use, lower WBC and higher IL-6 were predictors of higher PANSS total score (p0.05 for each). In subjects with cocaine use, lower total and differential WBC were predictors of higher PANSS total score (p0.04 for each). In younger, non-obese subjects with a negative UDS, higher monocytes and IL-6 were predictors of PANSS total score (p0.04 for each).Our findings provide additional evidence that inflammation may be associated with psychopathology and cognition in some patients with schizophrenia. Furthermore, there is preliminary evidence for differential effects of comorbid marijuana and cocaine use on these relationships.
