Dopamine supersensitivity psychosis (DSP) is observed in patients with schizophrenia under antipsychotic treatment, and it is characterized by rebound psychosis, an uncontrollable psychotic episode following a stable state and tardive dyskinesia. DSP, first described in patients taking typical antipsychotics in the late 1970s, sometimes appears even in patients who are treated with current atypical antipsychotics. It was recently demonstrated that DSP can have a negative impact on the long-term prognosis of schizophrenia patients and that DSP could be involved in the etiology of some cases of treatment-resistant schizophrenia...

This study aimed to evaluate the stigma and its correlates among patients with severe mental disorders. Patients with diagnosis of schizophrenia (N = 707), bipolar disorder (N = 344) and recurrent depressive disorder (N = 352) currently in clinical remission from 14 participating centres were assessed on Internalized Stigma of Mental Illness Scale (ISMIS). Patients with diagnosis of schizophrenia experienced higher level of alienation, sterotype endorsement, discrimination experience and total stigma when compared to patients with bipolar disorder and recurrent depressive disorder...

Olanzapine, an antipsychotic agent mainly used for treating schizophrenia, is frequently associated with body weight gain and diabetes mellitus. Nonetheless, studies have shown that not every individual is equally susceptible to olanzapine's weight-gaining effect. Therefore, Roman high and low avoidance rat strains were examined on their responsiveness to olanzapine treatment. The Roman high avoidance rat shares many behavioral and physiological characteristics with human schizophrenia, such as increased central dopaminergic sensitivity, whereas the Roman low avoidance rat has been shown to be prone to diet-induced obesity and insulin resistance...

Here, we investigated neurological soft signs (NSSs) in treatment resistant schizophrenia (TRS) vs treatment responder schizophrenia (SZ) patients. TRS is a severe condition, affecting approximately one-third of schizophrenia patients and representing a relevant clinical challenge. NSSs are neurological abnormalities reportedly described in schizophrenia patients and linked to dysregulated network connections. We explored the possibility that NSSs may be: i) more severe in TRS patients; ii) differentially associated to clinical/cognitive variables in TRS vs SZ; iii) predictive of having TRS...

BACKGROUND: When treatment-refractory schizophrenia shows an insufficient response to a trial of clozapine, clinicians commonly add a second antipsychotic, despite the lack of robust evidence to justify this practice. OBJECTIVES: The main objectives of the study were to establish the clinical effectiveness and cost-effectiveness of augmentation of clozapine medication with a second antipsychotic, amisulpride, for the management of treatment-resistant schizophrenia...

BACKGROUND: The role of oxidative stress in schizophrenia has been demonstrated, particularly in subjects with treatment-resistant schizophrenia (TRS). In such patients, the decreased levels of antioxidants in conjunction with the increased generation of reactive oxygen species in the brain exposes the neurons to a higher risk of damage. METHODS AND FINDINGS: We evaluated the association of deletion polymorphisms of two genes of the antioxidant Glutathione S-Transferase family, GSTT1 and GSTM1, with susceptibility to TRS...

Clozapine is an atypical antipsychotic used in the treatment of refractory schizophrenia. It has a well-known side effect profile, including agranulocytosis, decreased seizure threshold, and tardive dyskinesia. In addition, numerous case reports have described clozapine-induced stuttering in adults. However, there has been only one previous case report describing it in the adolescent population. In addition, concurrent lithium therapy has been shown to enhance the neurotoxic effects of antipsychotics and lower the seizure threshold...

BACKGROUND: The second-generation antipsychotics (SGAs) are associated with metabolic disturbances. Diabetic ketoacidosis (DKA) is a rare, but potentially fatal sign of acute glucose metabolism dysregulation, which may be associated with the use of SGAs. This study aims to review published reports of patients with schizophrenia and antipsychotic drug-associated DKA, focusing on the effective management of both conditions. METHODS: Using a predefined search strategy, we searched PubMed and EMBASE from their inception to July 2016...

Consultations for patients with chronic mental health conditions are conceived as meetings of experts: medical and experiential, respectively. Treatment decisions, in these terms, become a joint responsibility rather than handed down ex-cathedra. One resource for constituting decisions as 'shared' is the treatment recommendation - decisional authority can be invoked through its design. There is concern that people diagnosed with schizophrenia are infrequently involved in treatment decisions. However, the methods psychiatrists actually employ remain undefined...

Introduction: Clozapine is a well-recognized effective treatment for some patients with treatment-resistant schizophrenia (TRS). Although it has potential benefits and approximately 30% of patients have a clinical indication for clozapine use, prescription rates are low. Objective: To evaluate clozapine prescription trends over a 5-year period in a tertiary psychiatric hospital. Methods: In this observational study, data prospectively collected by the Medical and Statistical File Service (Serviço de Arquivo Médico e Estatístico) and the Pharmacy Division of Instituto de Psiquiatria de Santa Catarina between January 2010 and December 2014 were summarized and analyzed by investigators blinded to data collection...

Clozapine (CLZ), a dibenzodiazepine, is demonstrated as the optimal antipsychotic for patients suffering from treatment-resistant schizophrenia. Like many other drugs, understanding the concentration of CLZ in a patient's blood is critical for managing the patients' symptoms, side effects, and overall treatment efficacy. To that end, various electrochemical techniques have been adapted due to their capabilities in concentration-dependent sensing. An open question associated with electrochemical CLZ monitoring is whether drug-protein complexes (i...

INTRODUCTION: Catatonia is a rare and severe psychomotor condition in children and adolescents. In the current report, we aimed to review the recent literature. METHOD: Using a PRISMA approach, we searched MEDLINE between 1982 and 2017 using the keywords 'CATATONIA' and 'CHILD' or 'ADOLESCENT'. In total, we reviewed 130 reports (controlled study, N=4; clinical chart, N=23; case report, N=54; and editorial/review, N=42). RESULTS: Several aspects seem to be age specific: (1) although the clinical presentation resembles that in adults, some symptoms are important in children and adolescents (e...

OBJECTIVE: This study evaluated rates of all-cause mortality and self-harm in association with clozapine treatment in individuals with treatment-resistant schizophrenia. METHOD: A population-based cohort of 2,370 individuals with treatment-resistant schizophrenia after Jan. 1, 1996, was followed until death, first episode of self-harm, emigration, or June 1, 2013. Time to all-cause death and time to first episode of self-harm were analyzed in Cox regression models with time-varying treatment, adjusted for clinical and sociodemographic covariates...

Increased predisposition of schizophrenia patients (SP) to development of obesity and insulin resistance suggested common signaling pathway between metabolic syndrome (MetS) and schizophrenia. Deficiency of kynurenine-3-monooxygenase (KMO), enzyme catalyzing formation of 3-hydroxykynurenine (3-HK) from kynurenine (Kyn), a tryptophan (Trp) metabolite, might contribute to development of MetS as suggested by non-expression of KMO genes in human fat tissue and elevated serum concentrations of Kyn and its metabolites, kynurenic (KYNA) and anthranilic (ANA) acids, in diabetic patients and Zucker fatty rats (ZFR)...

BACKGROUND: Concerns exist that clozapine is underutilized in the management of treatment-resistant schizophrenia. Although a 2015 change in the US Food and Drug Administration (FDA) monitoring recommendations lowered the threshold of the absolute neutrophil count for treatment interruption from 1,500/μL to 1,000/μL and removed white blood cell count thresholds from the monitoring algorithm, the implications of this policy change on clozapine interruptions remain unknown. METHODS: We analyzed outpatient prescribing records for antipsychotic medications in the Veterans Integrated Service Network 7 (VISN 7) database between 1999 and 2012 to assess the potential impact of the recent changes in FDA neutropenia monitoring recommendations on clozapine treatment discontinuation...

BACKGROUND: Genes, molecules and neural circuits that are associated with, or confer risk to developing schizophrenia have been studied and mapped. It is hypothesized that certain neural systems may counterbalance familial risk of schizophrenia, and thus confer resilience to developing the disorder. This study sought to identify resting-state functional brain connectivity (rs-FC) representing putative risk or resilience endophenotypes in schizophrenia. METHODS: Resting-state functional magnetic resonance imaging (rs-fMRI) was performed in 42 individuals with treatment resistant schizophrenia (TRS), 16 unaffected first-degree family members (UFM) and 42 healthy controls...

Studies have suggested that stigma resistance plays an important role in the recovery from mental illness. However, there has been limited research in Asian countries that has examined the benefits of stigma resistance among the mentally ill in Asian populations. Hence, this study aimed to assess the prevalence of stigma resistance and establish the socio-demographic correlates of stigma resistance, as well as its association with internalised stigma and psychosocial outcomes among a multi-ethnic population of 280 outpatients with obsessive compulsive disorder (OCD), schizophrenia, depressive disorders and anxiety disorders in Singapore...

OBJECTIVE: Overestimating patients' medication adherence diminishes the ability of psychiatric care providers to prescribe the most effective treatment and to identify the root causes of treatment resistance in schizophrenia. This study was conducted to determine how credible patient drug adherence information (PDAI) might change prescribers' treatment decisions. METHODS: In an online survey containing 8 clinical case vignettes describing patients with schizophrenia, health care practitioners who prescribe antipsychotics to patients with schizophrenia were instructed to choose a preferred treatment recommendation from a set of predefined pharmacologic and non-pharmacologic options...

There is growing evidence that the cerebellum plays a crucial role in the pathophysiology of schizophrenia symptoms. Despite increasing evidence for cerebellar involvement in affective, attentive, and cognitive functions including language processing and perception, investigations of cerebellar contributions to auditory verbal hallucinations (AVH) in schizophrenia are lacking. Using structural magnetic resonance imaging at 3T, we investigated the data of 20 patients with schizophrenia and 14 matched healthy controls...
