Impaired insight in schizophrenia: impact on patient-reported and physician-reported outcome measures in a randomized controlled trial.

Background: Impaired insight poses a challenge in the treatment of patients with schizophrenia because of its potential to jeopardize therapeutic engagement and medication adherence. This study explored how insight impairment, graded from none to extreme, is related to patient-reported mental health status, depression, and neurocognition in schizophrenia.

Methods: In a post hoc analysis of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) study (NCT00014001), insight was measured using the Positive and Negative Syndrome Scale (PANSS) Item G12 (lack of insight).

25-Hydroxyvitamin D and metabolic-related laboratory values in women with schizophrenia and hyperprolactinemia.

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).

Controversies Surrounding the Use of Long-Acting Injectable Antipsychotic Medications for the Treatment of Patients with Schizophrenia.

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.

Insomnia and inflammation in phase 1 of the clinical antipsychotic trials of intervention effectiveness study.

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.

Monitoring for myocarditis during treatment initiation with clozapine.

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.

How to Evaluate Patients and Educate Them About Self-Examinations for Tardive Dyskinesia Between Appointments.

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.

Long-term effect of aripiprazole lauroxil on health-related quality of life in patients with schizophrenia.

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.

Longitudinal study of inflammatory markers and psychopathology in schizophrenia.

Objective: 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.

How to Assess Tardive Dyskinesia Symptom Improvement With Measurement-Based Care.

​​​​​​ 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.

Selecting Treatment for Patients With Tardive Dyskinesia Using Safety and Efficacy Evidence.

​​ 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).

A single assessment with the Brief Adherence Rating Scale (BARS) discriminates responders to long-acting injectable antipsychotic treatment in patients with schizophrenia.

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.

A Modified Delphi Consensus Study of the Screening, Diagnosis, and Treatment of Tardive Dyskinesia.

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.

Improving Cognition via Exercise (ICE): Study Protocol for a Multi-Site, Parallel-Group, Single-Blind, Randomized Clinical Trial Examining the Efficacy of Aerobic Exercise to Improve Neurocognition, Daily Functioning, and Biomarkers of Cognitive Change in Individuals with 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.

FDA-Approved Medications to Treat Tardive Dyskinesia.

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.

Psychosocial Implications of Tardive Dyskinesia in Patients With Mood Disorders Versus Schizophrenia.

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.

The characteristics of cognitive neuroscience tests in a schizophrenia cognition clinical trial: Psychometric properties and correlations with standard measures.

In comparison to batteries of standard neuropsychological tests, cognitive neuroscience tests may offer a more specific assessment of discrete neurobiological processes that may be aberrant in schizophrenia. However, more information regarding psychometric properties and correlations with standard neuropsychological tests and functional measures is warranted to establish their validity as treatment outcome measures. The N-back and AX-Continuous Performance Task (AX-CPT) are two promising cognitive neuroscience tests designed to measure specific components of working memory and contextual processing respectively.

Urinary tract infection, inflammation, and cognition in phase 1 of the Clinical Antipsychotic Trials of Intervention Effectiveness Study.

Background: 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.
