IntroductionAggressive behavior can be a dangerous complication of schizophrenia. Hostility is related to aggression. This study aimed to compare the effects of olanzapine, perphenazine, risperidone, quetiapine, and ziprasidone on hostility in schizophrenia.MethodsWe used the data that were acquired in the 18-month Phase 1 of the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) study. We analyzed the scores of the Positive and Negative Syndrome Scale (PANSS) hostility item in a subset of 614 patients who showed at least minimal hostility (a score ≥ 2) at baseline.ResultsThe primary analysis of hostility indicated an effect of difference between treatments (F4,1487 = 7.78, P < 0.0001). Olanzapine was significantly superior to perphenazine and quetiapine at months 1, 3, 6, and 9. It was also significantly superior to ziprasidone at months 1, 3, and 6, and to risperidone at months 3 and 6.DiscussionOur results are consistent with those of a similar post-hoc analysis of hostility in first-episode subjects with schizophrenia enrolled in the European First-Episode Schizophrenia Trial (EUFEST) trial, where olanzapine demonstrated advantages compared with haloperidol, quetiapine, and amisulpride.ConclusionOlanzapine demonstrated advantages in terms of a specific antihostility effect over the other antipsychotics tested in Phase 1 of the CATIE trial.

The Relationship

Background: Previous studies have implicated childhood trauma and abnormal brain-derived neurotrophic factor in the pathogenesis of schizophrenia. Here, we explored whether brain-derived neurotrophic factor levels mediated the relationship between childhood trauma and psychopathological symptoms in patients with first-episode schizophrenia. Methods: Patients with first-episode schizophrenia ( n = 192) and healthy controls ( n = 136) were enrolled. Childhood traumatic experiences and psychopathology were assessed by Childhood Trauma Questionnaire and Positive and Negative Syndrome Scale, respectively. Enzyme-linked immunosorbent assay was used to quantify brain-derived neurotrophic factor levels. Results: The patients with first-episode schizophrenia experienced more severe childhood trauma and had lower serum brain-derived neurotrophic factor levels than healthy controls. Emotional abuse and Childhood Trauma Questionnaire total score showed positive correlation with Positive and Negative Syndrome Scale positive, general psychopathological subscore and total score. Emotional neglect showed positive correlation with Positive and Negative Syndrome Scale positive subscore. Physical neglect was positively associated with Positive and Negative Syndrome Scale negative subscore. Emotional neglect and Childhood Trauma Questionnaire total score were negatively correlated with serum brain-derived neurotrophic factor levels. The serum brain-derived neurotrophic factor levels mediated the relationship between both Childhood Trauma Questionnaire total score and Positive and Negative Syndrome Scale total score and negative symptoms in the patients. The brain-derived neurotrophic factor levels also mediated the relationship between emotional neglect and Positive and Negative Syndrome Scale total score in the patients. Conclusion: Childhood trauma might contribute to the clinical symptoms of schizophrenia by affecting brain-derived neurotrophic factor levels. Perhaps we can prevent schizophrenia by reducing childhood traumatic experiences.

BackgroundEarly improvement with treatment is thought to be important in patients with first-episode schizophrenia, yet a valid definition is still outstanding.AimsTo develop a valid definition of early improvement and test its predictive validity regarding response and remission.MethodWe examined 188 in-patients with first-episode schizophrenia. Early improvement was defined as improvement in Positive and Negative Syndrome Scale (PANSS) total score at week 2, response as a 40% PANSS total score improvement at end-point, and remission according to consensus criteria.ResultsReasonable predictive validity of early improvement was found for a 46% PANSS total score improvement at week 2 and a 50% improvement for remission (area under the curve: response 0.707, remission 0.692). Estimated confidence intervals ranged from 26 to 62% PANSS reduction for response and remission.ConclusionsPatients with a first episode of schizophrenia should improve by at least 30% in PANSS total score at week 2 to achieve response and remission.

Background. Although patients with schizophrenia have increased rates of neurological soft signs, few studies have examined prospectively their trait or state characteristics in relation to psychopathology.Method. In a prospective study of 97 patients with first-episode schizophrenia (DSM-IV criteria) we assessed neurological soft signs and psychopathology at presentation and at 6 month follow-up for 73 cases. To establish whether soft signs were associated with variations in clinical state, neurological soft signs were measured using two validated examinations (Neurological Evaluation Scale and Condensed Neurological Examination); psychopathology was assessed using the Positive and Negative Syndrome Scale.Results. There was significant improvement in overall neurological function, primarily in motor-related and cortical signs, which were associated with improvement in psychopathology. Conversely, ‘harder’ signs were unrelated to improvement in psychopathology.Conclusions. Neurological soft signs in schizophrenia are heterogenous. Motor and cortical signs evidence state-like characteristics and vary with clinical course, while ‘harder’ signs evidence more static, trait-like characteristics in accordance with a neurodevelopmental basis.

AbstractBackground: Reported rates of depression in schizophrenia vary considerably.Objective: To measure the prevalence of depression in a first episode sample of people with schizophrenia.Methods: All referrals with a first episode of schizophrenia diagnosed using SCID interviews were assessed pre-discharge and again six months later. We used the Calgary Depression Scale for Schizophrenia (CDSS) and Positive and Negative Syndrome Scale (PANSS) to assess the severity of symptoms.Results: Pre-discharge, 10.4% of the sample met CDSS criteria for depression. According to the PANSS depression (PANSS -D) subscale, 3% of patients were depressed, with a mean score of 7.48 (SD = 2.97). Only 3% of patients pre-discharge were found to be depressed on both the CDSS and the PANSS-D. Six months later 6.5% were depressed according to the CDSS. However none reached depression criteria according to the PANSS-D. The CDSS correlated with PANSS-D both pre-discharge and at follow-up. Feelings of depression and self-deprecation were the most common symptoms at baseline and follow-up. The CDSS was unrelated to negative symptoms at both stages. A lifetime history of alcohol abuse increased the risk for depression.Conclusion: Rates of depression in this sample were low. The CDSS appears to discriminate between depression and negative symptoms. Like the general population, alcohol misuse is a risk factor for depression in first episode schizophrenia.

SummaryPurposeMany factors influencing compliance in schizophrenia have been reported in the literature. Our aim was to assess predictors of noncompliance in male patients with first-episode schizophrenia, schizophreniform and schizoaffective disorder in a naturalistic setting.Subjects and methodsFifty-six male patients, discharged from hospital, were included in a 1-year follow-up study. Psychopathological symptoms were assessed with positive and negative syndrome scale at admission and discharge, while extrapyramidal side effects were recorded weekly during hospitalisation using the Simpson–Angus and Barnes akathisia scales. Socio-demographic and some other variables were also recorded.ResultsThirty patients (53.6%) dropped out of treatment in the first year and 21 of them relapsed. With the Cox survival analysis three predictors of noncompliance were found: diagnosis of schizophrenia versus the other two diagnoses, positive symptoms at admission, and lack of insight at discharge.DiscussionIn spite of a specific methodology and selection of only first-episode male patients, the results are in accordance with the findings of other authors. This confirms the universality of noncompliance in psychotic patients.ConclusionsFirst-episode patients have a high dropout rate. However, in compliant patients, the relapse rate was low, and therefore special attention and compliance-promoting interventions in first-episode patients are needed.

Objetivo: Ainda não está claro quais são os fatores de risco para a esquizofrenia resistente ao tratamento (ERT) em primeiro episódio psicótico (PEP). O objetivo deste trabalho é investigar indicadores de risco para ERT em PEP. Métodos: Foram selecionados 53 pacientes em primeiro episódio psicótico, com diagnóstico de esquizofrenia, que deram entrada à enfermaria de psiquiatria do Hospital das Clínicas Luzia de Pinho Melo entre 2011 e 2015. Ao ser admitido na enfermaria, o paciente era avaliado com a Escala de Sintomas para as Síndromes Positiva e Negativa (Positive and Negative Syndrome Scale – PANSS) e recebia tratamento inicial por 4 semanas. Caso sua resposta fosse inferior a 40% de redução na PANSS, o antipsicótico era trocado, e as escalas eram aplicadas novamente após mais 4 semanas. Após a falha com dois antipsicóticos, em doses plenas, por 4 semanas cada, a clozapina era introduzida, e o paciente era considerado ERT. Uma regressão logística foi aplicada onde sexo, idade de início, tempo de doença não tratada, uso de substâncias, avaliação global do funcionamento inicial e PANSS inicial total foram inseridos como variáveis independentes, e ERT foi inserida como variável dependente. Resultados: Tempo de doença não tratada apresentou significância de p = 0,038 e Exp (B) = 4,29, enquanto que PANSS total apresentou p = 0,012 e Exp (B) = 1,06. Conclusão: Identificar os fatores associados à resistência precoce ao tratamento poderia permitir aos clínicos evitar o atraso na introdução da clozapina e prevenir um pior prognóstico para esses pacientes.

Abstract Objective: Microstate analysis is a powerful tool to probe the brain functions, and changes in microstates under electroencephalography (EEG) have been repeatedly reported in patients with schizophrenia. This study aimed to investigate the dynamics of EEG microstates in drug-naïve, first-episode schizophrenia (FE-SCH) and to test the relationship between EEG microstates and clinical symptoms.Methods: Resting-state EEG were recorded for 23 patients with FE-SCH and 23 healthy controls using a 64-channel cap. Three parameters, i.e., contribution, duration, and occurrence, of the four microstate classes were calculated. Group differences in EEG microstates and their clinical symptoms (assessed using the Positive and Negative Syndrome Scale) were analyzed.Results: Compared with healthy controls, patients with FE-SCH showed increased duration, occurrence and contribution of microstate class C and decreased contribution and occurrence of microstate class D. In addition, the score of positive symptoms in PANSS was negatively correlated with the occurrence of microstate D.Conclusions: Our findings showed abnormal patterns of EEG microstates in drug-naïve, first-episode schizophrenia, which might help distinguish individuals with schizophrenia in the early stage and develop early intervention strategies.

Objective. It has been reported that the prevalence of metabolic syndrome (MS) in multiepisode patients with schizophrenia is 35.3%, which is 2- to 4-fold higher than in the general population. The study is designed to compare the glycolipid metabolism in patients with first-episode schizophrenia (FES) with sex- and age-matched healthy controls to investigate changes in serum levels of homocysteine (Hcy), macrophage migration inhibitory factor (MIF), and high-sensitive C-reactive protein (hs-CRP) and their relationships with the glycolipid metabolism in patients with FES. Methods. His case-control study included 88 patients diagnosed with FES and 88 sex- and age-matched healthy controls. Patient psychopathology was assessed using the Positive and Negative Syndrome Scale (PANSS), Young Mania Rating Scale (YMRS), and 17-item Hamilton Rating Scale for Depression (HAMD-17). Patients with FES were classified into MS and non-MS groups. Results. There were significant differences in the education level, body mass index (BMI), and waist circumference between the patients with FES and healthy controls (all p > 0.05 ). The patients with FES had higher levels of FPG and blood glucose at the oral glucose tolerance test (OGTT) (2 h glucose) concomitant with higher proportion of impaired glucose tolerance (IGT) and homeostasis model assessment of insulin resistance (HOMA2-IR) than healthy controls (all p < 0.001 ). It was revealed that the patients with FES showed higher serum levels of Hcy, MIF, and hs-CRP than healthy controls (all p < 0.001 ). The serum level of Hcy shared positive correlations with the score of PANSS totals (r = 0.551) and the negative syndrome of the PANSS scale (r = 0.494). The serum levels of MIF and hs-CRP was only positively correlated with the negative syndrome of the PANSS scale (r = 0.320 and r = 0.446). The level of Hcy shared positive correlations with the levels of FPG, 2 h glucose, and HOMA2-IR; the level of MIF was only positively correlated with the level of HOMA2-IR; the level of hs-CRP had a positive correlation with both levels of FPG and 2 h glucose (all p < 0.001 ). The levels of Hcy, MIF, and hs-CRP all shared positive correlations with the TG level and negative correlations with the HDL-C level (all p < 0.001 ). There were remarkable differences between the MS and non-MS groups with regard to BMI, waist circumference, negative subscale of the PANSS scale, FPG, TG, and HDL-C (all p < 0.05 ). Elevated levels of Hcy, MIF, and hs-CRP were detected in the MS group compared to the non-MS group (all p < 0.05 ). Conclusion. These findings suggest that increased concentrations of HCY, MIF, and hs-CRP may contribute to the abnormal glycolipid metabolism in the context of schizophrenia.

Introduction: Duration of untreated psychosis (DUP) is an important predictor for prognosis in first episode of psychotic disorders. Caregivers often seek help from alternative healers first and health professional later. These would delay proper treatments for the patients, resulting in more severe symptoms and lower functioning on their visit to medical facility. The present study aims to find the association between DUP, symptoms severity, and global functioning in patients with first-episode psychotic disorders. Methods: We identified 100 patients with first episode of psychotic disorders and their caregivers. The instruments used were Brief Psychotic Rating Scale (BPRS), Positive and Negative Syndrome Scale (PANSS), Premorbid Schizoid-Schizotypal Traits (PSST), and Global Assessment of Functioning (GAF). Results: There were no significant association between BPRS, PANSS, PSST, and GAF scores and DUP in our subjects. Nevertheless, we found that men had significantly longer DUP compared to women. Conclusion: We found significant association between sex and DUP in this study. Longer DUP leads to delayed treatments and poorer prognosis. Further study is required to confirm our finding.
