Abstract
RATIONALE The long-term effectiveness of olanzapine and aripiprazole in real clinical conditions at flexible doses in patients after hospital discharge has not been evaluated yet. OBJECTIVES This study was a multicenter retrospective cohort study. Patients with schizophrenia (n = 398) were prescribed olanzapine (n = 303) or aripiprazole (n = 95) at hospital discharge. The continuation of olanzapine or aripiprazole at 26, 52, or 104 weeks after the hospital discharge were compared using a Cox proportional hazards model and adjusted for possible confounders. RESULTS The Kaplan-Meier survival curves revealed that the continuation of olanzapine at 26 (P = 0.001) and 52 weeks (P = 0.018) was significantly higher than that of aripiprazole but not at 104 weeks. Olanzapine was better than aripiprazole in efficacy at 26 (hazard ratio: 0.321, 95% confidence interval: 0.159-0.645, P = 0.001), 52 (hazard ratio: 0.405, 95% confidence interval: 0.209-0.786, P = 0.008), and 104 weeks (hazard ratio: 0.438, 95% confidence interval: 0.246-0.780, P = 0.005). Aripiprazole was better than olanzapine in tolerability at 104 weeks (hazard ratio: 4.574, 95% confidence interval: 1.415-14.787, P = 0.011). Rates after two years continuation of olanzapine and aripiprazole were not significantly different in patients with less than five years' duration of illness, but olanzapine was more commonly maintained for more than two years in those patients who had been ill for over five years' due to its greater efficacy. CONCLUSION Olanzapine treatment showed better continuation rates at 26 and 52 after hospital discharge than aripiprazole, whereas maintenance with the two antipsychotics did not differ significantly at 104 weeks, due reduced tolerability of long-term olanzapine treatment.

Abstract
There is a paucity of biomarkers for the prediction of treatment response in schizophrenia. In this study, we aimed to investigate whether diminished antipsychotic treatment response in relapsed versus first-episode schizophrenia can be revealed and predicted by a panel of blood-based biomarkers. A cross-sectional cohort consisting of 655 schizophrenia patients at different episodes and 606 healthy controls, and a longitudinal cohort including 52 first-episode antipsychotic-naïve schizophrenia patients treated with the same antipsychotic drugs during the 5-year follow-up of their first three episodes were enrolled. Plasma biomarker changes and symptom improvement were compared between the drug-free phase of psychosis onset and after 4 weeks of atypical antipsychotic drug (AAPD) treatment. In response to treatment, the extent of changes in the biomarkers of bioenergetic, purinergic, phospholipid and neurosteroid metabolisms dwindled down as number of episode and illness duration increased in relapsed schizophrenia. The changes of creatine, inosine, progesterone, allopregnanolone, cortisol and PE(16:0/22:6) were significantly correlated with the improvement of symptomatology. Inosine and progesterone at baseline were shown to be strong predictive biomarkers of treatment response. The results suggest that AAPD treatment response is diminished in the context of relapse, and our findings open new avenues for understanding the pathophysiology of treatment-resistance schizophrenia.

Ther Adv Psychopharmacol 2021; 11:20451253211029490. [PMID: 34349980 PMCID: PMC8295959 DOI: 10.1177/20451253211029490] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Accepted: 06/13/2021] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND The pragmatic management of psychotic disorders is more complex than that delivered in a controlled trial environment. Therefore, this study aims to evaluate the real-world effectiveness of aripiprazole long-acting injectable (ALAI) and compare it with another commonly used long-acting anti-psychotic, once-monthly paliperidone palmitate (PP1M). METHODS This naturalistic, independent 4-year mirror image study compared the mean number and length of hospital admissions 2 years before and 2 years after treatment initiation with ALAI. Retention rates, discontinuation reasons and level of adherence were also recorded. Furthermore, indirect comparisons were made between treatment outcomes on ALAI and PP1M. RESULTS A total of 109 eligible patients with a severe mental illness (65% with schizophrenia and 35% with other diagnosis) commenced on ALAI and 173 patients (69% with schizophrenia and 31% with other diagnoses) initiated on PP1M were included. Of these, 37% on ALAI and 34% on PP1M stopped treatment at 2 years; retention rates were most favourable for the schizophrenia group on PP1M. Patients were more likely to discontinue due to lack of effectiveness on ALAI and due to tolerability issues on PP1M. Those who continued for 2 years on ALAI (n = 69), demonstrated an overall decrease of 84% in the mean number and 88% in the mean length of hospital admissions compared with the 2 years before initiation. Although patients on ALAI appeared to have a significantly higher bed occupancy the 2-year period before initiation than patients on PP1M, the reductions in hospitalizations were comparable across both cohorts after 2 years of treatment. CONCLUSIONS The introduction of ALAI had a substantial impact on long-term clinical outcomes in this naturalistic cohort; more than half of patients continued treatment and had no admission during 2 years of follow up. There were no significant differences in hospitalisation rates between patients on ALAI and PP1M at 2 years.

Abstract
Resumo Ancorado numa perspectiva psicossocial, frente aos desafios da reinserção social e da composição de estratégias de cuidado em liberdade, este estudo tem por objetivo analisar as narrativas dos familiares de ouvidores de vozes sobre suas experiências como cuidadores. Foram realizadas entrevistas narrativas com familiares de participantes de um grupo de ouvidores de vozes em um Centro de Atenção Psicossocial (Caps) da cidade de Pelotas, no Rio Grande do Sul, Brasil. A partir da análise temática, produziram-se três eixos temáticos: (1) experiência de ouvir vozes e necessidade de cuidado; (1) família: práticas de cuidado; e (3) estratégias terapêuticas: tecendo redes de cuidado compartilhadas em saúde mental. As narrativas dos cuidadores reportam dificuldades na convivência com familiares que ouvem vozes, sobrecarga de trabalho relacionada ao cuidado e desafios enfrentados no cotidiano. Destaca-se a importância de espaços grupais de ajuda mútua que possam auxiliar os cuidadores.

Abstract
BACKGROUND The symptoms and signs of schizophrenia have been linked to high levels of dopamine in specific areas of the brain (limbic system). Antipsychotic drugs block the transmission of dopamine in the brain and reduce the acute symptoms of the disorder. An original version of the current review, published in 2012, examined whether antipsychotic drugs are also effective for relapse prevention. This is the updated version of the aforesaid review. OBJECTIVES To review the effects of maintaining antipsychotic drugs for people with schizophrenia compared to withdrawing these agents. SEARCH METHODS We searched the Cochrane Schizophrenia Group's Study-Based Register of Trials including the registries of clinical trials (12 November 2008, 10 October 2017, 3 July 2018, 11 September 2019). SELECTION CRITERIA We included all randomised trials comparing maintenance treatment with antipsychotic drugs and placebo for people with schizophrenia or schizophrenia-like psychoses. DATA COLLECTION AND ANALYSIS We extracted data independently. For dichotomous data we calculated risk ratios (RR) and their 95% confidence intervals (CIs) on an intention-to-treat basis based on a random-effects model. For continuous data, we calculated mean differences (MD) or standardised mean differences (SMD), again based on a random-effects model. MAIN RESULTS The review currently includes 75 randomised controlled trials (RCTs) involving 9145 participants comparing antipsychotic medication with placebo. The trials were published from 1959 to 2017 and their size ranged between 14 and 420 participants. In many studies the methods of randomisation, allocation and blinding were poorly reported. However, restricting the analysis to studies at low risk of bias gave similar results. Although this and other potential sources of bias limited the overall quality, the efficacy of antipsychotic drugs for maintenance treatment in schizophrenia was clear. Antipsychotic drugs were more effective than placebo in preventing relapse at seven to 12 months (primary outcome; drug 24% versus placebo 61%, 30 RCTs, n = 4249, RR 0.38, 95% CI 0.32 to 0.45, number needed to treat for an additional beneficial outcome (NNTB) 3, 95% CI 2 to 3; high-certainty evidence). Hospitalisation was also reduced, however, the baseline risk was lower (drug 7% versus placebo 18%, 21 RCTs, n = 3558, RR 0.43, 95% CI 0.32 to 0.57, NNTB 8, 95% CI 6 to 14; high-certainty evidence). More participants in the placebo group than in the antipsychotic drug group left the studies early due to any reason (at seven to 12 months: drug 36% versus placebo 62%, 24 RCTs, n = 3951, RR 0.56, 95% CI 0.48 to 0.65, NNTB 4, 95% CI 3 to 5; high-certainty evidence) and due to inefficacy of treatment (at seven to 12 months: drug 18% versus placebo 46%, 24 RCTs, n = 3951, RR 0.37, 95% CI 0.31 to 0.44, NNTB 3, 95% CI 3 to 4). Quality of life might be better in drug-treated participants (7 RCTs, n = 1573 SMD -0.32, 95% CI to -0.57 to -0.07; low-certainty evidence); probably the same for social functioning (15 RCTs, n = 3588, SMD -0.43, 95% CI -0.53 to -0.34; moderate-certainty evidence). Underpowered data revealed no evidence of a difference between groups for the outcome 'Death due to suicide' (drug 0.04% versus placebo 0.1%, 19 RCTs, n = 4634, RR 0.60, 95% CI 0.12 to 2.97,low-certainty evidence) and for the number of participants in employment (at 9 to 15 months, drug 39% versus placebo 34%, 3 RCTs, n = 593, RR 1.08, 95% CI 0.82 to 1.41, low certainty evidence). Antipsychotic drugs (as a group and irrespective of duration) were associated with more participants experiencing movement disorders (e.g. at least one movement disorder: drug 14% versus placebo 8%, 29 RCTs, n = 5276, RR 1.52, 95% CI 1.25 to 1.85, number needed to treat for an additional harmful outcome (NNTH) 20, 95% CI 14 to 50), sedation (drug 8% versus placebo 5%, 18 RCTs, n = 4078, RR 1.52, 95% CI 1.24 to 1.86, NNTH 50, 95% CI not significant), and weight gain (drug 9% versus placebo 6%, 19 RCTs, n = 4767, RR 1.69, 95% CI 1.21 to 2.35, NNTH 25, 95% CI 20 to 50). AUTHORS' CONCLUSIONS For people with schizophrenia, the evidence suggests that maintenance on antipsychotic drugs prevents relapse to a much greater extent than placebo for approximately up to two years of follow-up. This effect must be weighed against the adverse effects of antipsychotic drugs. Future studies should better clarify the long-term morbidity and mortality associated with these drugs.

Abstract
This is a report of a joint World Psychiatric Association/International College of Neuropsychopharmacology (WPA/CINP) workgroup concerning the risk/benefit ratio of antipsychotics in the treatment of schizophrenia. It utilized a selective but, within topic, comprehensive review of the literature, taking into consideration all the recently discussed arguments on the matter and avoiding taking sides when the results in the literature were equivocal. The workgroup's conclusions suggested that antipsychotics are efficacious both during the acute and the maintenance phase, and that the current data do not support the existence of a supersensitivity rebound psychosis. Long-term treated patients have better overall outcome and lower mortality than those not taking antipsychotics. Longer duration of untreated psychosis and relapses are modestly related to worse outcome. Loss of brain volume is evident already at first episode and concerns loss of neuropil volume rather than cell loss. Progression of volume loss probably happens in a subgroup of patients with worse prognosis. In humans, antipsychotic treatment neither causes nor worsens volume loss, while there are some data in favor for a protective effect. Schizophrenia manifests 2 to 3 times higher mortality vs the general population, and treatment with antipsychotics includes a number of dangers, including tardive dyskinesia and metabolic syndrome; however, antipsychotic treatment is related to lower mortality, including cardiovascular mortality. In conclusion, the literature strongly supports the use of antipsychotics both during the acute and the maintenance phase without suggesting that it is wise to discontinue antipsychotics after a certain period of time. Antipsychotic treatment improves long-term outcomes and lowers overall and specific-cause mortality.

Abstract
BACKGROUND The comparative effectiveness of antipsychotic long-acting injections (LAIs) and oral medication is not clear due to various methodological problems. METHODS To compare the effectiveness of LAIs and oral antipsychotics in preventing readmission in patients with schizophrenia, we performed a within-subject analysis of data collected from 75,274 patients hospitalized with schizophrenia over a 10-year period (2008-2017). Readmission rates were compared according to medication status (non-medication, oral medication alone, and LAI medication). Each admission episodes were compared according to medication status before admission. RESULTS Total 132,028 episodes of admission were analyzed. During 255,664 person-years of total observation, 101,589 outcome events occurred. Comparing LAI to only oral medication, IRR was 0.71 (0.64-0.78, P < 0.001). IRR of LAI to only oral medication of first index admission was 0.74 (0.65-0.86). As hospitalization was repeated, IRR of second, third, and fourth or more index admission decreased 0.65 (0.53-0.79), 0.56 (0.43-0.76), and 0.42 (0.31-0.56), respectively. CONCLUSIONS LAI treatment reduced the readmission rate by 29% compared with oral medication in real-world settings. Moreover, LAIs reduced the readmission rate by 58% in patients with repeated admissions. The more readmissions, the greater the effect of LAIs in reducing the risk of re-hospitalization compared with oral antipsychotics.

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

Identifying Modifiable Risk Factors for Relapse in Patients With Schizophrenia in China. Front Psychiatry 2020; 11:574763. [PMID: 33061925 PMCID: PMC7518216 DOI: 10.3389/fpsyt.2020.574763] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2020] [Accepted: 08/24/2020] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Preventing relapse of schizophrenic patients is really a challenge. The present study sought to provide more explicit evidence and factors of different grades and weights by a series of step-by-step analysis through χ2 test, logistic regression analysis and decision-tree model. The results of this study may contribute to controlling relapse of schizophrenic patients. METHODS A total of 1,487 schizophrenia patients were included who were 18-65 years of age and discharged from 10 hospitals in China from January 2009 to August 2009 and from September 2011 to February 2012 with improvements or recovery of treatment effect. We used a questionnaire to collect information about relapse and correlative factors during one year after discharge by medical record collection and telephone interview. The χ2 test and logistic regression analysis were used to identify risk factors and high-risk factors firstly, and then a decision-tree model was used to find predictive factors. RESULTS The χ2 test found nine risk factors which were associated with relapse. Logistic regression analysis also showed four high-risk factors further (medication adherence, occupational status, ability of daily living, payment method of medical costs). At last, a decision-tree model revealed four predictors of relapse; it showed that medication adherence was the first grade and the most powerful predictor of relapse (relapse rate for adherence vs. nonadherence: 22.9 vs. 55.7%, χ2 = 116.36, p < 0.001). The second grade factor was occupational status (employment vs. unemployment: 19.7 vs. 42.7%, χ2 = 17.72, p < 0.001); the third grade factors were ability of daily living (normal vs. difficult: 28.4 vs. 54.3%, χ2 = 8.61, p = 0.010) and household income (household income ≥ 3000 RMB vs. <3000 RMB: 28.6 vs. 42.4%, χ2 = 6.30, p = 0.036). The overall positive predictive value (PPV) of the logistic regression was 0.740, and the decision-tree model was 0.726. Both models were reliable. CONCLUSIONS For schizophrenic patients discharged from hospital, who had good medication adherence, more higher household income, be employed and normal ability of daily living, would be less likely to relapse. Decision tree provides a new path for doctors to find the schizophrenic inpatient's relapse risk and give them reasonable treatment suggestions after discharge.

Abstract
The cardinal symptoms of psychosis include hallucination and delusion, which can be both distressing and disabling. International guidelines recommend cognitive behavioural therapy for psychosis (CBTp) as an adjunctive intervention to medication management. Considering the difficulty in the widespread dissemination of the individual CBTp, group CBTp is an alternative in improving patients' access to psychological intervention. Although it has been found feasible and effective in various studies, systematic review on group CBTp, particularly in Asia, was not identified. Hence, this systematic review tried to examine the recent evidence of group CBTp in Asia in order to shed light on its implementation in routine psychiatric care. A relevant literature search was conducted in three databases (Pubmed, Web of Knowledge, and PsycINFO) during the period from January 2000 to December 2018. A total of 114 journal articles were identified. After a full-text review, four studies met our inclusion and exclusion criteria. Despite methodological shortcomings, positive results were found in terms of improvements on psychotic symptoms, functioning, and quality-of-life. These encouraging results indicate the need for future research studies with more rigorous methodology, leading to a better understanding on the applicability and effectiveness of group CBTp in the Asian context.

Abstract
Resumo Este estudo se trata de uma revisão sistematizada da literatura e teve como objetivo revisar os achados sobre o tema ouvidores de vozes, enfatizando a relação deles com suas vozes. A investigação foi realizada em duas bases de dados, PubMed e Lilacs, sem limite temporal e com os seguintes termos em inglês: “voice hearing” OR “auditory verbal hallucination”. A busca resultou no total de 2.464 títulos de artigos que foram examinados quanto à adequação ao objetivo. Identificaram-se 126 artigos para análise de texto completo, dos quais 35 preencheram critérios para inclusão. Evidenciou-se que o sentido que o ouvidor atribui às vozes está atrelado a sua história de vida, fazendo ele as considerar ameaçadoras, intrusivas, controladoras, ou gentis, amigáveis e positivas. Portanto, o sentido atribuído às vozes se mostrou determinante na relação que o ouvidor estabelecerá com elas mesmas, bem como a forma como ele se relaciona socialmente.

Abstract
INTRODUCTION Schizophrenia is a debilitating condition with three main symptom domains: positive, negative, and cognitive. Approximately one-third of persons with schizophrenia will fail to respond to treatment. Growing evidence suggests that treatment-resistant (refractory) schizophrenia (TRS) may be a distinct condition from treatment-respondent schizophrenia. There is limited evidence on effective treatments for TRS, and a lack of standardized diagnostic criteria for TRS has hampered research. Areas covered: A literature search was conducted using Pubmed.gov and the EMBASE literature database. The authors discuss the pragmatic definitions of TRS and review treatments consisting of antipsychotic monotherapy and augmentation strategies. Expert opinion: Currently available first-line antipsychotic medications are generally effective at treating the positive symptoms of schizophrenia, leaving residual negative and cognitive symptoms. Before diagnosing TRS, rule out any pharmacodynamic or pharmacokinetic failures. Most evidence supports clozapine as having the most efficacy for TRS. If clozapine is used, it should be optimized, and serum levels should be at least 350-420 ng/ml. If clozapine is unable to be tolerated, some evidence suggests olanzapine at dosages up to 40mg/day can be useful. Augmentation strategies have weak evidence. Tailoring treatment to the specific domain is the preferred approach, and the use of a structured assessment/outcome measure is encouraged.

Abstract
PURPOSE A retrospective study was conducted to evaluate the time to discontinuation (TTD) of the first- (FGAs) and second-generation antipsychotics (SGAs). METHODS In total, 918 treatment episodes of patients with schizophrenia, initiated on one of the investigated drugs on an outpatient basis during 2004-2006, were entered into the study. The primary outcome was the duration of the investigated treatment episode. Discontinuation was defined when either patients were admitted or the investigated drug had been stopped for more than 28 days. We used the Cox proportional hazard model to compare hazards of discontinuations among 8 SGAs versus 2 FGAs (haloperidol and sulpiride). The follow-up period was up to 18 months. RESULTS During the follow-up period, clozapine had the highest rate of continuous treatment in the primary analysis: clozapine, 40.6%; olanzapine, 23.4%; aripiprazole, 22.9%; amisulpride, 21.9%; zotepine, 21.3%; sulpiride, 17.0%; risperidone, 12.8%; quetiapine, 12.5%; haloperidol, 10.6%; and ziprasidone, 10.4%. Compared with haloperidol, 5 SGAs had significantly longer TTD (adjusted hazard ratios and 95% confidence intervals): clozapine (0.403, 0.267-0.607), olanzapine (0.611, 0.439-0.849), aripiprazole (0.570, 0.407-0.795), amisulpride (0.680, 0.487-0.947), and zotepine (0.687, 0.497-0.948), but only clozapine had significantly longer TTD compared with sulpiride (0.519, 0.342-0.786). The sensitivity analysis showed similar results. IMPLICATIONS/CONCLUSIONS The current findings suggested that SGAs or FGAs are not homogeneous groups. Clozapine has the highest rate of continuous treatment among SGAs, and haloperidol is not the representative drug for all FGAs. Furthermore, antipsychotics dropout rate is high in naturalistic situation. A good service model needs to be constructed to enhance antipsychotic treatment adherence of people with schizophrenia.

Abstract
OBJECTIVE There is evidence that over time health outcomes of people with schizophrenia are deteriorating rather than improving both in terms of mortality rate and levels of morbidity, even in Australia where service resourcing is substantial. Our objective was to examine the evidence of whether poor outcomes reflect decreases in treatment effectiveness and, if so, what are the barriers to improving standards of care. This review will argue that the confidence of clinicians to diagnose schizophrenia early, and provide assertive and long-term care, may be being undermined by a series of controversies in the published literature and discrepancies in clinical practice guidelines. METHOD A critical review was conducted of the evidence regarding six issues of high clinical relevance to the treatment of schizophrenia formulated as questions: (1) Is schizophrenia a progressive disease? (2) Does relapse contribute to disease progression and treatment resistance? (3) When should the diagnosis of schizophrenia be made? (4) Should maintenance antipsychotic medication be discontinued in fully remitted first-episode patients? (5) Do antipsychotic medications cause deleterious reductions in cortical grey matter volumes? and (6) Are long-acting injectable antipsychotics more effective in reducing relapse rate compared to oral formulations? RESULTS There is reliable evidence for schizophrenia being a progressive disease with emergent treatment resistance in most cases, that relapse contributes to this treatment resistance, that maintenance antipsychotic medication should not be discontinued in remitted first-episode patients, that antipsychotic medication does not appear to cause deleterious grey matter volume changes, that maintenance antipsychotic medication reduces the mortality rate in schizophrenia and that long-acting injectable antipsychotics are more effective in preventing relapse than oral formulations. CONCLUSION There is an urgent need to re-engineer the early management of schizophrenia and to routinely evaluate this type of innovation within practice-based research networks. A proposal for an assertive treatment algorithm is included.

Abstract
BACKGROUND Sub-anesthetic doses of the NMDA antagonist ketamine have been shown to model the formation and stability of delusion in human subjects. The latter has been predicted to be due to aberrant prediction error resulting in enhanced destabilization of beliefs. To extend the scope of this model, we investigated the effect of administration of low dose systemic ketamine on memory in a rodent model of memory reconsolidation. METHODS Systemic ketamine was administered either prior to or immediately following auditory fear memory reactivation in rats. Memory strength was assessed by measuring freezing behavior 24h later. Follow up experiments were designed to investigate an effect of pre-reactivation ketamine on short-term memory (STM), closely related memories, and basolateral amygdala (BLA) specific destabilization mechanisms. RESULTS Rats given pre-reactivation, but not post-reactivation, ketamine showed larger freezing responses 24h later compared to vehicle. This enhancement was not observed 3h after the memory reactivation, nor was it seen in a closely related contextual memory. Prior inhibition of a known destabilization mechanism in the BLA blocked the effect of pre-reactivation ketamine. CONCLUSIONS Pre- but not post-reactivation ketamine enhances fear memory. These data together with recent data in human subjects supports a model of delusion fixity that proposes that aberrant prediction errors result in enhanced destabilization and strengthening of delusional belief.

Abstract
OBJECTIVE The goals of this study were to (i) estimate the rate of non-response to first-line treatment in first-episode schizophrenia, (ii) evaluate other outcomes associated with symptom non-response and (iii) identify demographic, baseline clinical and early treatment response predictors of non-response. METHODS This was a single-site, longitudinal cohort study assessing the effects of treatment with flupenthixol decanoate according to a standardised protocol over 12 months in patients with schizophrenia, schizophreniform and schizo-affective disorders. RESULTS Of 126 patients who received at least one dose of study medication, 84 (67%) completed the study. Fifteen (12%) met our predefined criteria for non-response. Non-responders were younger and at baseline had more prominent disorganised symptoms, poorer social and occupational functioning, poorer quality of life for psychological, social and environmental domains, more prominent neurological soft signs (NSS) and lower body mass index. At endpoint, the non-responders were characterised by higher levels of symptomatology in all domains, poorer functional outcome, poorer quality of life and greater cognitive impairments. They also had more prominent NSS and lower body mass index. The strongest predictors of non-response were more prominent baseline NSS and poor early (7 weeks) treatment response. CONCLUSIONS Results are consistent with a lower rate of refractoriness to treatment in first-episode schizophrenia compared with multi-episode samples.

Abstract
BACKGROUND Long-acting depot injections of drugs such as flupenthixol decanoate are extensively used as a means of long-term maintenance treatment for schizophrenia. OBJECTIVES To evaluate the effects of flupenthixol decanoate in comparison with placebo, oral antipsychotics and other depot neuroleptic preparations for people with schizophrenia and other severe mental illnesses, in terms of clinical, social and economic outcomes. SEARCH METHODS We identified relevant trials by searching the Cochrane Schizophrenia Group Trials Register in March 2009 and then for this update version, a search was run in April 2013. The register is based on regular searches of CINAHL, EMBASE, MEDLINE and PsycINFO. References of all identified studies were inspected for further trials. We contacted relevant pharmaceutical companies, drug approval agencies and authors of trials for additional information. SELECTION CRITERIA All randomised controlled trials that focused on people with schizophrenia or other similar psychotic disorders where flupenthixol decanoate had been compared with placebo or other antipsychotic drugs were included. All clinically relevant outcomes were sought. DATA COLLECTION AND ANALYSIS Review authors independently selected studies, assessed trial quality and extracted data. For dichotomous data we estimated risk ratios (RR) with 95% confidence intervals (CI) using a fixed-effect model. Analysis was by intention-to-treat. We summated normal continuous data using mean difference (MD), and 95% CIs using a fixed-effect model. We presented scale data only for those tools that had attained prespecified levels of quality. Using Grading of Recommendations Assessment, Development and Evaluation (GRADE) we created 'Summary of findings tables and assessed risk of bias for included studies. MAIN RESULTS The review currently includes 15 randomised controlled trials with 626 participants. No trials compared flupenthixol decanoate with placebo.One small study compared flupenthixol decanoate with an oral antipsychotic (penfluridol). Only two outcomes were reported with this single study, and it demonstrated no clear differences between the two preparations as regards leaving the study early (n = 60, 1 RCT, RR 3.00, CI 0.33 to 27.23,very low quality evidence) and requiring anticholinergic medication (1 RCT, n = 60, RR 1.19, CI 0.77 to 1.83, very low quality evidence).Ten studies in total compared flupenthixol decanoate with other depot preparations, though not all studies reported on all outcomes of interest. There were no significant differences between depots for outcomes such as relapse at medium term (n = 221, 5 RCTs, RR 1.30, CI 0.87 to 1.93, low quality evidence), and no clinical improvement at short term (n = 36, 1 RCT, RR 0.67, CI 0.36 to 1.23, low quality evidence). There was no difference in numbers of participants leaving the study early at short/medium term (n = 161, 4 RCTs, RR 1.23, CI 0.76 to 1.99, low quality evidence) nor with numbers of people requiring anticholinergic medication at short/medium term (n = 102, 3 RCTs, RR 1.38, CI 0.75 to 2.25, low quality evidence).Three studies in total compared high doses (100 to 200 mg) of flupenthixol decanoate with the standard doses (˜40mg) per injection. Two trials found relapse at medium term (n = 18, 1 RCT, RR 1.00, CI 0.27 to 3.69, low quality evidence) to be similar between the groups. However people receiving a high dose had slightly more favourable medium term mental state results on the Brief Psychiatric Rating Scale (BPRS) (n = 18, 1 RCT, MD -10.44, CI -18.70 to -2.18, low quality evidence). There was also no significant difference in the use of anticholinergic medications to deal with side effects at short term (2 RCTs n = 47, RR 1.12, CI 0.83 to 1.52 very low quality evidence). One trial comparing a very low dose of flupenthixol decanoate (˜6 mg) with a low dose (˜9 mg) per injection reported no difference in relapse rates (n = 59, 1 RCT, RR 0.34, CI 0.10 to 1.15, low quality evidence). AUTHORS' CONCLUSIONS In the current state of evidence, there is nothing to choose between flupenthixol decanoate and other depot antipsychotics. From the data reported in clinical trials, it would be understandable to offer standard dose rather than the high dose depot flupenthixol as there is no difference in relapse. However, data reported are of low or very low quality and this review highlights the need for large, well-designed and reported randomised clinical trials to address the effects of flupenthixol decanoate.

Abstract
It has long been suspected that relapse in schizophrenia is associated with disease progression in so far as time to response is longer, negative and other symptoms persist, some patients become treatment refractory and neuroprogression in terms of structural brain changes may occur. This article examines the evidence for illness progression after relapse in patients with schizophrenia. It reports on indirect evidence obtained from retrospective, naturalistic and brain-imaging studies, as well as a few prospective studies examining pre- and post-relapse treatment response. Findings suggest that the treatment response after relapse is variable, with many patients responding rapidly, others exhibiting protracted impairment of response and a subgroup displaying emergent refractoriness. This subgroup comprises about 1 in 6 patients, irrespective of whether it is the first or a subsequent relapse, and even when the delay between onset of first symptoms of relapse and initiation of treatment is brief. While there is a lack of well-designed studies investigating the post-relapse treatment outcome, available evidence gives sufficient cause for concern that, in addition to the considerable psychosocial risks, an additional risk of biological harm may be associated with relapse.

Abstract
BACKGROUND Multiple relapses characterise the course of illness in most patients with schizophrenia, yet the nature of these episodes has not been extensively researched and clinicians may not always be aware of important implications. METHODS We critically review selected literature regarding the nature and underlying neurobiology of relapse. RESULTS Relapse rates are very high when treatment is discontinued, even after a single psychotic episode; a longer treatment period prior to discontinuation does not reduce the risk of relapse; many patients relapse soon after treatment reduction and discontinuation; transition from remission to relapse may be abrupt and with few or no early warning signs; once illness recurrence occurs symptoms rapidly return to levels similar to the initial psychotic episode; while most patients respond promptly to re-introduction of antipsychotic treatment after relapse, the response time is variable and notably, treatment failure appears to emerge in about 1 in 6 patients. These observations are consistent with contemporary thinking on the dopamine hypothesis, including the aberrant salience hypothesis. CONCLUSIONS Given the difficulties in identifying those at risk of relapse, the ineffectiveness of rescue medications in preventing full-blown psychotic recurrence and the potentially serious consequences, adherence and other factors predisposing to relapse should be a major focus of attention in managing schizophrenia. The place of antipsychotic treatment discontinuation in clinical practice and in placebo-controlled clinical trials needs to be carefully reconsidered.

Abstract
This study investigated whether illness progression and treatment refractoriness emerge after relapse in schizophrenia. We compared outcomes in a cohort treated with a standardized protocol for the first and second episodes of illness. The sample comprised 31 participants who (1) had successfully completed a 2-year open-label treatment phase with risperidone long-acting injection (RLAI) for a first episode of schizophrenia; (2) underwent an intermittent treatment extension phase up to 3 years or until recurrence, and (3) entered a further 2-year treatment phase with RLAI for a recurrence episode. For the patients who remained in treatment (n = 14 [45%]), Positive and Negative Syndrome Scale score reductions, response rates, remission rates, time to response, time to remission, functional outcome scores, and modal RLAI doses were similar for the 2 treatment periods. However, 17 (55 %) of the 31 patients discontinued the study in the second episode compared with 14 (28%) of 50 patients in the first episode, suggesting reduced effectiveness of antipsychotics when reintroduced after illness recurrence. Most notably, emergent treatment nonresponsiveness was observed in 5 participants (16%), consistent with the hypothesis that relapse may be biologically harmful in a subset of patients.

Abstract
While placebo-controlled studies continue to be required by regulatory authorities for the licensing of new drugs for schizophrenia to demonstrate maintenance of effect, the long-term risks to participants are largely unknown. We compared the response to treatment with paliperidone palmitate before and after relapse in such a study. This was a post-hoc analysis of 97 patients with schizophrenia who relapsed while receiving placebo in a multinational relapse prevention clinical trial. Patients underwent an initial open-label treatment phase of 33 weeks (comprising a 9-week transition phase to switch patients to paliperidone palmitate, a 12-week flexible-dose phase and a 12-week fixed-dose phase); a double-blind phase of variable duration during which stabilized patients were randomized 1:1 to either continue paliperidone palmitate or receive placebo; and an optional 52-week open-label flexible-dose extension phase. There was a small but significant increase in PANSS total scores after eight months of treatment following relapse (56.7[12.68]) compared with prerelapse endpoint (54.5[11.74]) (p=0.026). Fourteen of 97 (14.4%) patients who had initially responded favorably to treatment met predefined nonresponse criteria in the postrelapse treatment phase, suggesting that treatment refractoriness may evolve in a subset of patients after relapse. However, relapses occurred in 18% of patients randomized to ongoing treatment in the double-blind phase, raising the possibility that treatment failure may also evolve in patients receiving continuous treatment. These findings may help inform decisions regarding the future of placebo-controlled trials in schizophrenia.

Abstract
BACKGROUND The symptoms and signs of schizophrenia have been firmly linked to high levels of dopamine in specific areas of the brain (limbic system). Antipsychotic drugs block the transmission of dopamine in the brain and reduce the acute symptoms of the disorder. This review examined whether antipsychotic drugs are also effective for relapse prevention. OBJECTIVES To review the effects of maintaining antipsychotic drugs for people with schizophrenia compared to withdrawing these agents. SEARCH METHODS We searched the Cochrane Schizophrenia Group's Specialised Register (November 2008), with additional searches of MEDLINE, EMBASE and clinicaltrials.gov (June 2011). SELECTION CRITERIA We included all randomised trials comparing maintenance treatment with antipsychotic drugs and placebo for people with schizophrenia or schizophrenia-like psychoses. DATA COLLECTION AND ANALYSIS We extracted data independently. For dichotomous data we calculated relative risks (RR) and their 95% confidence intervals (CI) on an intention-to-treat basis based on a random-effects model. For continuous data, we calculated mean differences (MD) or standardised mean differences (SMD) again based on a random-effects model. MAIN RESULTS The review currently includes 65 randomised controlled trials (RCT(s)) and 6493 participants comparing antipsychotic medication with placebo. The trials were published from 1959 to 2011 and their size ranged between 14 and 420 participants. In many studies the methods of randomisation, allocation and blinding were poorly reported. Although this and other potential sources of bias limited the overall quality, the efficacy of antipsychotic drugs for maintenance treatment in schizophrenia was clear. Antipsychotic drugs were significantly more effective than placebo in preventing relapse at seven to 12 months (primary outcome; drug 27%, placebo 64%, 24 RCT(s), n=2669, RR 0.40 CI 0.33 to 0.49, number needed to treat for an additional beneficial outcome (NNTB 3 CI 2 to 3). Hospitalisation was also reduced, however, the baseline risk was lower (drug 10%, placebo 26%, 16 RCT(s), n=2090, RR 0.38 CI 0.27 to 0.55, NNT 5 CI 4 to 9). More participants in the placebo group than in the antipsychotic drug group left the studies early due to any reason (at 7-12 months: drug 38%, placebo 66%, 18 RCT(s), n=2420, RR 0.55 CI 0.46 to 0.66, NNTB 4 CI 3 to 5) and due to inefficacy of treatment (at 7-12 months: drug 20%, placebo 50%, 18 RCT(s), n=2420, RR 0.36 CI 0.28 to 0.45, NNTB 3 CI 2 to 4). Quality of life was better in drug-treated participants (3 RCT(s), n=527, SMD -0.62 CI -1.15 to -0.09). Conversely, antipsychotic drugs as a group and irrespective of duration, were associated with more participants experiencing movement disorders (e.g. at least one movement disorder: drug 16%, placebo 9%, 22 RCT(s), n=3411, RR 1.55 CI 1.25 to 1.93, NNTH 25 CI 13 to 100), sedation (drug 13%, placebo 9%, 10 RCT(s), n=146, RR 1.50 CI 1.22 to 1.84, number needed to treat for an additional harmful outcome (NNTH) not significant) and weight gain (drug 10%, placebo 6%, 10 RCT(s), n=321, RR 2.07 CI 1.31 to 3.25, NNTH 20 CI 14 to 33). The results of the primary outcome were robust in a number of subgroup, meta-regression and sensitivity analyses, the main exception being that the drug-placebo difference in longer trials was smaller than in shorter trials. AUTHORS' CONCLUSIONS The results clearly demonstrate the superiority of antipsychotic drugs compared to placebo in preventing relapse. This effect must be weighed against the side effects of antipsychotic drugs. Future studies should focus on outcomes of social participation and clarify the long-term morbidity and mortality associated with these drugs.

Abstract
These guidelines from the British Association for Psychopharmacology address the scope and targets of pharmacological treatment for schizophrenia. A consensus meeting, involving experts in schizophrenia and its treatment, reviewed key areas and considered the strength of evidence and clinical implications. The guidelines were drawn up after extensive feedback from the participants and interested parties, and cover the pharmacological management and treatment of schizophrenia across the various stages of the illness, including first-episode, relapse prevention, and illness that has proved refractory to standard treatment. The practice recommendations presented are based on the available evidence to date, and seek to clarify which interventions are of proven benefit. It is hoped that the recommendations will help to inform clinical decision making for practitioners, and perhaps also serve as a source of information for patients and carers. They are accompanied by a more detailed qualitative review of the available evidence. The strength of supporting evidence for each recommendation is rated.

Abstract
BACKGROUND Chlorpromazine, one of the first generation of antipsychotic drugs, is effective in the treatment of schizophrenia. For most people schizophrenia is a life-long disorder but about a quarter of those who have a first psychotic breakdown do not go on to experience further breakdowns. Most people with schizophrenia are prescribed antipsychotic drugs, although use is often intermittent. The effects of stopping medication are not well researched in the context of systematic reviews. OBJECTIVES To quantify the effects of stopping chlorpromazine for people with schizophrenia stable on this drug. SEARCH STRATEGY We supplemented an electronic search of the Cochrane Schizophrenia Group Trials Register (March 2006) with reference searching of all identified studies. SELECTION CRITERIA We included all relevant randomised clinical trials. DATA COLLECTION AND ANALYSIS We independently inspected citations and abstracts, ordered papers and re-inspected and quality assessed these. We independently extracted data and resolved disputes during regular meetings. We analysed dichotomous data using fixed effects relative risk (RR) and the 95% confidence interval (CI). For continuous data, where possible, we calculated the weighted mean difference (WMD). We excluded the data where more than 40% of people were lost to follow up. MAIN RESULTS We included ten trials involving 1042 people with schizophrenia stable on chlorpromazine. Even in the short term, those who remained on chlorpromazine were less likely to experience a relapse compared to people who stopped taking chlorpromazine (n=376, 3 RCTs, RR 6.76 CI 3.37 to 13.54, NNH XX CI XX to XX). Medium term (n=850, 6 RCTs, RR 4.04 CI 2.81 to 5.8, NNH 4 CI 3 to 7) and long term data were similar (n=510, 3 RCTs, RR 1.70 CI 1.44 to 2.01, NNH XX CI XX to XX). People allocated to chlorpromazine withdrawal were not significantly more likely to stay in the study compared with those continuing chlorpromazine treatment (n=374, 1 RCT, RR 1.14 CI 0.55 to 2.35). In sensitivity analyses, there was a significant difference in the 'relapse' outcome between trials for those diagnosed according to checklist criteria compared to those with a clinical diagnosis. AUTHORS' CONCLUSIONS This review confirms clinical experience and quantifies the risks of stopping chlorpromazine medication for a group of people with schizophrenia who are stable on this drug. With its moderate adverse effects, chlorpromazine is likely to remain one of the most widely prescribed treatments for schizophrenia.

Abstract
The authors review the literature on cognitive-behavioral approaches to the treatment of schizophrenia. They begin by providing a historical context to explain the recent resurgence of interest in this area. Next, they provide an overview of studies of cognitive-behavioral interventions that target poor insight, medication nonadherence, and refractory symptoms. Insight and nonadherence are emphasized because these are particularly common and problematic areas that present major stumbling blocks in the treatment of patients suffering from schizophrenia that are not yet sufficiently addressed by the interventions clinicians currently have in their treatment arsenal. The authors conclude that support exists for the efficacy of interventions derived from cognitive-behavioral approaches in improving some aspects of insight into illness, increasing adherence to medication, ameliorating the severity of symptoms, and mitigating other negative consequences of schizophrenia. Finally, the authors offer guidelines for future work in this area and emphasize the importance of identifying patients who are most likely to benefit from the use of cognitive-behavioral approaches.

Abstract
BACKGROUND 'Relapse' is a common outcome indicator in intervention studies in schizophrenia. In community studies it is frequently equated with hospitalisation and in psychopharmacological studies with predetermined symptom scores. Its clinical meaning, however, remains undefined. METHOD Consensus on the defining features of 'relapse' in schizophrenia used by academic and clinical schizophrenia experts in the UK, was investigated using a four stage Delphi process. A two panel, four stage, Delphi based methodology was used to investigate the implicit meanings of 'relapse' in clinical practice. A multidisciplinary panel of twelve members each listed anonymously ten indicators of relapse. A second panel, of ten experienced psychiatrists, rated the 188 submitted indicators from essential-unimportant (1-5). This panel completed a one day workshop during the remaining Delphi rounds ending with a structured discussion of the results. RESULTS Very strong consensus was achieved on the relative importance of potential relapse indicators. There was complete agreement about some aspects of a definition of relapse (such as recurrence of positive symptoms) and a number of the complex issues underlying the concept were clearly articulated. CONCLUSIONS This four stage Delphi process achieved consensus on core features of relapse. The elucidation of the "softer" features at the threshold between normal fluctuations in functioning and the start of relapse require continuing investigations.

Abstract
In the United Kingdom there are plans to close most mental hospitals over the next 10 years. There is continuing uncertainty about the effectiveness of community psychiatric services that will be expected to cope with mental hospital inpatients after discharge, most of whom have schizophrenia. A survey was conducted to assess the severity of illness among such patients and implications for their future care. All 222 patients in non-psychogeriatric long stay wards of a mental hospital who met research diagnostic criteria for schizophrenia were interviewed by two psychiatrists with the comprehensive psychopathological rating scale to establish the prevalence of psychiatric symptomatology. A complete interview was not possible for 28 patients, mainly for reasons related to their schizophrenia. Despite energetic pharmacological and social treatments almost half of the 194 patients interviewed had enduring florid psychotic symptoms that presented as one or more delusions or auditory hallucinations, or both, and a sizable proportion showed behaviour that would set them apart in a community setting. The results illustrate a problem that is still imperfectly understood by policy makers and administrators in central and local government and in health authorities who are responsible for planning and implementing services for psychiatric care in the community.

Abstract
Twenty six consecutive patients with neuroleptic-induced Parkinson's syndrome (NIPS) are described. Their median age was 61 years, 60% were female, and most had received chronic neuroleptic medication for psychiatric indications. The clinical features were indistinguishable from idiopathic Parkinson's disease, except for the presence of co-existing orofacial chorea, limb dyskinesia or akathisia which provided an aetiological clue in 11 cases. Complete resolution of NIPS occurred in only two patients, one of whom later developed Parkinson's disease. Sixteen patients were treated with 300-1000 mg levodopa/benserazide for up to 4 years with few adverse effects but therapeutic response was disappointing.

Abstract
A randomised double blind placebo controlled trial is the most reliable method of assessing putative new developments in medical treatment. In schizophrenia, however, some clinicians believe that relapse contributes to long term deterioration and therefore that patients exposed to either placebo or an inactive new treatment may be put at a disadvantage in the long run if the trial leads to an additional relapse. A seven year follow up of patients included in a randomised placebo controlled trial of fluphenazine decanoate, in which 66% of the group given placebo relapsed compared with 8% of those who received the active drug, permitted examination of any long term adverse consequences in those patients who had received placebo. Seventy six (94%) of the 81 patients in the original trial were followed up. At the end of the follow up period there were no consistent or important differences in any measure of clinical or social outcome between the patients who had received placebo and those who had received the active drug. This negative finding has implications for the debate on the risk of placebo controlled trials of maintenance treatment in chronic schizophrenia.

Abstract
The following are key factors to consider in assessing a patient for long-term neuroleptics: 1. Who--accurate diagnosis of schizophrenia is of primary concern. There are no good prognostic indicators other than a history of repeated relapses and positive responses to neuroleptics. 2. When and for how long--should always be considered for the patient who has had more than two acute episodes. The first year post-acute episode back in the community is extremely critical. Consider maintaining patient on tapering dosage of medication for at least four to five years. 3. What benefits--symptoms of acute psychosis respond, those of chronic defect state do not. Medication also can act as buffer against stress. 4. Dosages--standard range is the equivalent of 300-800 mg. of Thorazine for most patients. Dose range for depot administration of Prolixin decanoate is 25-62.5 mg. 2-4 week intervals. Differences within this range may not be important. Data about very low doses (one-tenth standard dose) and megadoses (4-5 times standard dose) are inconsistent. 5. Risks--extrapyramidal symptoms, tardive dyskinesia, and akinetic depression are the most prevalent risks. Extrapyramidal symptoms can often be controlled effectively with dosage reduction. However, anticholinergic drugs are the treatment of choice during acute phases, and for the first 3-5 months post-acute phase. Tardive dyskinesia rarely occurs after a few weeks or months, but occurs most commonly beginning after two years of drug treatment. The usual form is persistent, but transient forms also occur. The earliest signs are reversible in some patients.(ABSTRACT TRUNCATED AT 250 WORDS)
