Abstract
BACKGROUND 22q11.2 deletion syndrome confers significant risk for the development of schizophrenia. While current recommendations regarding the management of psychotic symptoms in affected individuals are generally in keeping with treatment guidelines for general schizophrenia populations, evidence for the use of clozapine has come from case reports and retrospective observational data. As no reviews on the topic currently exist, a systematic review of clozapine use in 22q11.2 deletion syndrome was completed. METHODS In November 2023, a literature search was completed using both PubMed and Scopus to identify English-language articles that reported the use of clozapine in humans with 22q11.2 deletion syndrome. RESULTS Twenty-six articles describing 57 individuals were deemed eligible for inclusion. Most individuals had a diagnosis of treatment-resistant schizophrenia. Where reported, the mean or median dose of clozapine was relatively low, and the majority of individuals exhibited a good response (approximately 65.5% across individual case reports/series). While seizures were unsurprisingly the most commonly reported serious adverse effect, the majority of individuals were able to remain on (or be restarted on) clozapine by having their dose decreased and/or by adding an anticonvulsant (most commonly valproate). CONCLUSIONS This review reaffirms that individuals with 22q11.2 deletion syndrome may benefit from clozapine therapy even at a low dose, assuming they meet criteria for treatment-resistant schizophrenia and provided no contraindications exist. However, given the increased incidence of seizures in 22q11.2 deletion syndrome, the use of prophylactic anticonvulsant therapy should be considered, and hypoparathyroidism/hypocalcemia screened for and corrected before the initiation of clozapine. It is also recommended that clozapine blood levels be monitored.

Clozapine in Treatment-Resistant Schizophrenia and Its Augmentation with Electroconvulsive Therapy in Ultra-Treatment-Resistant Schizophrenia. Biomedicines 2023; 11:biomedicines11041072. [PMID: 37189691 DOI: 10.3390/biomedicines11041072] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Revised: 03/29/2023] [Accepted: 03/31/2023] [Indexed: 04/05/2023] Open
Abstract
Clozapine is considered the gold standard for patients with treatment-resistant schizophrenia (TRS) who have previously tried other antipsychotics at adequate doses (two or more, with at least one being atypical). However, despite optimal treatment, a subgroup of TRS patients with what is known as ultra-treatment-resistant schizophrenia (UTRS) fails to respond to clozapine, which occurs in 40–70% of cases. The most common approach to manage UTRS involves augmenting clozapine with pharmacological or non-pharmacological interventions, with a growing body of evidence that supports the use of electroconvulsive therapy (ECT) as an augmenter. This prospective non-randomized 8-week study, which followed the TRIPP Working Group guidelines and is one of few that separate TRS from UTRS, aimed to evaluate the effectiveness of clozapine in TRS patients and the efficacy of ECT augmentation of clozapine in UTRS patients. Patients with TRS were assigned to receive clozapine alone (clozapine group), whereas UTRS patients received bilateral ECT in addition to their current medication regimen (ECT plus clozapine group). The severity of symptoms was evaluated using the Clinical Global Impression Scale (CGI) and Positive and Negative Syndrome Scale (PANSS) at baseline and at the end of the 8-week trial. Both treatment approaches resulted in improved CGI and PANSS scores. The results suggest that both clozapine and ECT are effective treatment options for patients with TRS and UTRS, respectively, and that adherence to guidelines should provide a better frame for future clinical studies.

Abstract
Clozapine is currently the only antipsychotic with demonstrated efficacy in treatment-refractory schizophrenia (TRS). However, response to clozapine differs widely between TRS patients, and there are no available clinical or neural predictive indicators that could be used to increase or accelerate the use of clozapine in patients who stand to benefit. Furthermore, it remains unclear how the neuropharmacology of clozapine contributes to its therapeutic effects. Identifying the mechanisms underlying clozapine's therapeutic effects across domains of symptomatology could be crucial for development of new optimized therapies for TRS. Here, we present results from a prospective neuroimaging study that quantitatively related heterogeneous patterns of clinical clozapine response to neural functional connectivity at baseline. We show that we can reliably capture specific dimensions of clozapine clinical response by quantifying the full variation across item-level clinical scales, and that these dimensions can be mapped to neural features that are sensitive to clozapine-induced symptom change. Thus, these features may act as "failure modes" that can provide an early indication of treatment (non-)responsiveness. Lastly, we related the response-relevant neural maps to spatial expression profiles of genes coding for receptors implicated in clozapine's pharmacology, demonstrating that distinct dimensions of clozapine symptom-informed neural features may be associated with specific receptor targets. Collectively, this study informs prognostic neuro-behavioral measures for clozapine as a more optimal treatment for selected patients with TRS. We provide support for the identification of neuro-behavioral targets linked to pharmacological efficacy that can be further developed to inform optimal early treatment decisions in schizophrenia.

Abstract
The aim of our study was to evaluate the effectiveness of lurasidone augmentation of clozapine in treatment-resistant schizophrenia (SZ) in a retrospective chart review. From the medical records of 916 SZ patients, we identified 16 individuals treated with a combination of clozapine and lurasidone. The detailed clinical data are described separately for each patient. We compared the Clinical Global Impression—Severity (CGI-S) scores between three points of observation: before the treatment and one month and two months after its initiation. CGI Improvement (CGI-I) scores were used to evaluate the treatment response between the first and last points of observation. The vast majority of patients (14/16, 87.5%) responded to lurasidone augmentation of clozapine (CGI-I scores 1 or 2). Therapeutic effects were observable after 3–12 weeks of treatment (median 6 (4–6)). A reduction in CGI-S scores was observed after the first month of observation. There was an observable reduction in positive, depressive and anxiety symptoms, as well as an improvement in psychosocial functioning. Two patients discontinued treatment due to side effects. Our study suggests that lurasidone augmentation of clozapine may lead to improvements in a broad range of SZ symptom dimensions.

Visual P300 as a neurophysiological correlate of symptomatic improvement by a virtual reality-based computer AT system in patients with auditory verbal hallucinations: A Pilot study. J Psychiatr Res 2022; 151:261-271. [PMID: 35512620 DOI: 10.1016/j.jpsychires.2022.04.027] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2022] [Revised: 04/09/2022] [Accepted: 04/20/2022] [Indexed: 11/24/2022]
Abstract
Previous comparative trials showed that virtual reality (VR) therapies achieved larger effects than gold-standard cognitive-behavioral therapy (CBT) on overall auditory verbal hallucinations (AVHs). However, no trial has examined the corresponding underlying electrophysiological mechanisms. We performed a pilot randomized comparative trial evaluating the efficacy of a virtual reality-based computer AT system (CATS) over CBT for schizophrenia (SCZ) patients with treatment-resistant AVHs and explored these potential electrophysiological changes via the visual P300 component. Patients (CATS, n = 32; CBT, n = 33) completed the clinical assessments pre- and post-interventions and at 12-week follow-up. The visual P300 were measured before and after both therapies. The analysis of changes in psychiatric symptoms used linear mixed-effects models, and the P300 response in temporal and time-frequency domains was analyzed with repeated-measures analysis of variance. There was no interaction effect between change in clinical symptoms and treatment group. However, several statistically significant within-group improvements were found for CATS and CBT over time. AVH improved significantly after both treatments, as measured with the Psychotic Symptom Rating Scales-Auditory Hallucinations (PSYRATS-AH) sub-scores. Especially for the CATS group, omnipotence beliefs, anxiety symptoms, self-esteem, and quality of life also remained improved at the 12-week follow-up. Moreover, P300 amplitude had a significant interaction effect and correlation with AVH response. Overall, our analysis did not demonstrate general clinical superiority of CATS over CBT, but CATS improved refractory AVH in SCZ patients, likely by increasing P300 amplitude. These findings support the continued development of CATS for persistent AVH and suggest further trials to clarify the neurological effects of CATS.

Abstract
About 40%-70% of the patients with treatment-resistant schizophrenia have a poor response to adequate treatment with clozapine. The impact of clozapine-resistant schizophrenia (CRS) is even greater than that of treatment resistance in terms of severe and persistent symptoms, relapses and hospitalizations, poorer quality of life, and healthcare costs. Such serious consequences often compel clinicians to try different augmentation strategies to enhance the inadequate clozapine response in CRS. Unfortunately, a large body of evidence has shown that antipsychotics, antidepressants, mood stabilizers, electroconvulsive therapy, and cognitive-behavioural therapy are mostly ineffective in augmenting clozapine response. When beneficial effects of augmentation have been found, they are usually small and of doubtful clinical significance or based on low-quality evidence. Therefore, newer treatment approaches that go beyond the evidence are needed. The options proposed include developing a clinical consensus about the augmentation strategies that are most likely to be effective and using them sequentially in patients with CRS. Secondly, newer approaches such as augmentation with long-acting antipsychotic injections or multi-component psychosocial interventions could be considered. Lastly, perhaps the most effective way to deal with CRS would be to optimize clozapine treatment, which might prevent clozapine resistance from developing. Personalized dosing, adequate treatment durations, management of side effects and non-adherence, collaboration with patients and caregivers, and addressing clinician barriers to clozapine use are the principal ways of ensuring optimal clozapine treatment. At present, these three options could the best way to manage CRS until research provides more firm directions about the effective options for augmenting clozapine response.

Abstract
Clozapine remains the only drug treatment likely to benefit patients with treatment resistant schizophrenia. Its use is complicated by an increased risk of neutropenia and so there are stringent monitoring requirements and restrictions in those with previous neutropenia from any cause or from clozapine in particular. Despite these difficulties clozapine may yet be used following neutropenia, albeit with caution. Having had involvement with 14 cases of clozapine use in these circumstances we set out our approach to the assessment of risks and benefits, risk mitigation and monitoring with a practical guide.

Abstract
OBJECTIVE This study aimed to assess the clinical effectiveness and cognitive effects of maintenance electroconvulsive therapy (mECT) in patients with schizophrenia or schizoaffective disorder and explore factors associated with both outcomes. METHODS In this retrospective cohort study, we examined clinical records of 47 patients with a Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) diagnosis of schizophrenia or schizoaffective disorder treated with mECT at an academic mental health hospital between April 2010 and July 2016. Sixty-two mECT courses were reviewed. We assessed clinical effectiveness and cognitive effects as well as factors associated with response to treatment, including psychiatric diagnosis, concomitant pharmacological treatment, and previous treatment response. RESULTS Maintenance electroconvulsive therapy was able to maintain clinical response in 48 (77%) treatment courses. Significant cognitive adverse effects were reported in 7 (11%) of the courses. Use of antipsychotic, antidepressant or benzodiazepine medications, psychiatric disorder, and sex were not associated with response. CONCLUSION This study shows meaningful clinical effectiveness and good tolerability of mECT in patients with resistant schizophrenia over extended periods.

Abstract
OBJECTIVES The aim of this study was to survey and describe the contemporary practice of electroconvulsive therapy (ECT) in the Kingdom of Denmark (Denmark, Greenland, and the Faroe Islands). METHODS Data regarding number of ECTs and number of patients with different diagnoses treated with ECT were retrieved from the Danish National Patient Registry. In addition, a 45-item questionnaire was sent to all psychiatric departments practicing ECT in Denmark (n = 26), Greenland (n = 1), and the Faroe Islands (n = 1). RESULTS According to the Danish National Patient Registry, a total of 21,730 ECTs were administered to 1891 unique patients in 2017. All departments responded to the survey. The psychiatric departments' attitude toward ECT was generally favorable and in accord with official guidelines. Maintenance ECT was used in all departments but one. Bilateral electrode placement was preferred. All departments used a preselected age-based dosing strategy. Involuntary ECT was performed in 96% of the psychiatric departments, but infrequently (3% of all treatments). All departments used a Thymatron (brief pulse) device, and in 71% of the departments, ECT was given in a specialized ECT unit and preanesthetic evaluation was carried out in all departments. The departments reported several different practices regarding documentation and monitoring of treatment effect, patient consent, screening for side effects (including cognitive side effects), and guidelines for the discharge of ECT patients. CONCLUSIONS Electroconvulsive therapy is frequently used in Denmark, Greenland, and the Faroe Islands in a relatively uniform way in adherence with clinical guidelines.

Abstract
AIM To evaluate clinical and biological efficacy and safety of electroconvulsive therapy (ECT) in patients with treatment-resistant paranoid schizophrenia. MATERIAL AND METHODS Determination of CNS specific biological markers (BDNF, NSE, S100B), together with markers of inflammation and CNS alteration (IL-2, CPK, CPK-MB), and clinical evaluation were performed in two groups of patients: the ECT + antipsychotic treatment group (n=66) and the antipsychotic treatment group (n=32). RESULTS AND CONCLUSION In the ECT + antipsychotic treatment group, the more pronounced reduction of psychotic symptoms has been revealed compared with subjects on antipsychotic treatment as monotherapy. Patients receiving ECT showed no increase in plasma levels of inflammation and CNS alteration biomarkers (NSE, S100B, CPK, CPK-MB, IL-2). The plasma level of BDNF, capable to characterize both the efficacy and safety of antipsychotic therapy, had a more pronounced upward trend in subjects with combined electroconvulsive and antipsychotic treatment, which may indicate good tolerability and high effectiveness of ECT.

Abstract
BACKGROUND Treatment options for clozapine resistance are diverse whereas, in contrast, the evidence for augmentation or combination strategies is sparse. AIMS We aimed to extract levels of evidence from available data and extrapolate recommendations for clinical practice. METHODS We conducted a systematic literature search in the PubMed/MEDLINE database and in the Cochrane database. Included meta-analyses were assessed using Scottish Intercollegiate Guidelines Network criteria, with symptom improvement as the endpoint, in order to develop a recommendation grade for each clinical strategy identified. RESULTS Our search identified 21 meta-analyses of clozapine combination or augmentation strategies. No strategies met Grade A criteria. Strategies meeting Grade B included combinations with first- or second-generation antipsychotics, augmentation with electroconvulsive therapy for persistent positive symptoms, and combination with certain antidepressants (fluoxetine, duloxetine, citalopram) for persistent negative symptoms. Augmentation strategies with mood-stabilisers, anticonvulsants, glutamatergics, repetitive transcranial magnetic stimulation, transcranial direct current stimulation or cognitive behavioural therapy met Grades C-D criteria only. CONCLUSION More high-quality clinical trials are needed to evaluate the efficacy of add-on treatments for symptom improvement in patients with clozapine resistance. Applying definitions of clozapine resistance would improve the reporting of future clinical trials. Augmentation with second-generation antipsychotics and first-generation antipsychotics can be beneficial, but the supporting evidence is from low-quality studies. Electroconvulsive therapy may be effective for clozapine-resistant positive symptoms.

Abstract
UNLABELLED Treatment-resistant schizophrenia (TRS) is common and debilitating. A subgroup of patients even has clozapine-resistant schizophrenia (CRS). We aimed to evaluate the efficacy and safety of electroconvulsive therapy (ECT) augmentation of clozapine for CRS. Systematic literature search of randomized controlled trials (RCTs) reporting on ECT augmentation of clozapine in CRS. Co-primary outcomes included symptomatic improvement at post-ECT assessment and study endpoint. Eighteen RCTs (n = 1769) with 20 active treatment arms were identified and meta-analyzed. Adjunctive ECT was superior to clozapine regarding symptomatic improvement at post-ECT assessment (Standardized Mean Difference (SMD) = -0.88, 95% Confidence Interval (CI): -1.33 to -0.44; I2 = 86%, P = 0.0001) and endpoint assessment (SMD: -1.44, 95%CI: -2.05 to -0.84; I2 = 95%, P < 0.00001), separating as early as week 1-2 (SMD = -0.54, 95%CI: -0.88 to -0.20; I2 = 77%, P = 0.002). Adjunctive ECT was also superior regarding study-defined response at post-ECT assessment (53.6% vs. 25.4%, Risk Ratio (RR) = 1.94, 95%CI: 1.59-2.36; I2 = 0%, P < 0.00001, number-needed-to-treat (NNT) = 3, 95%CI: 3-5) and endpoint assessment (67.7% vs. 41.4%, RR = 1.66, 95%CI: 1.38-1.99; I2 = 47%, P < 0.00001, NNT = 4, 95%CI: 3-8), and remission at post-ECT assessment (13.3% vs. 3.7%, RR = 3.28, 95%CI: 1.80-5.99; I2 = 0%, P = 0.0001, NNT = 13, 95%CI: 6-100) and endpoint assessment (23.6% vs. 13.3%, RR = 1.80, 95%CI: 1.39 to 2.35; I2 = 5%, P < 0.0001, NNT = 14, 95%CI: 6-50). Patient-reported memory impairment (24.2% vs. 0%; RR = 16.10 (95%CI: 4.53-57.26); I2 = 0%, P < 0.0001, number-needed-to-harm (NNH) = 4, 95%CI: 2-14) and headache (14.5% vs 1.6%; RR = 4.03 (95%CI: 1.54-10.56); I2 = 0%, P = 0.005, NNH = 8, 95%CI: 4-50) occurred more frequently with adjunctive ECT. No significant group differences were found regarding discontinuation and other adverse effects. Despite increased frequency of self-reported memory impairment and headache, ECT augmentation of clozapine is a highly effective and relatively safe treatment for CRS.

Abstract
BACKGROUND Clozapine is the last-line antipsychotic agent for refractory schizophrenia. To date, there is no convincing evidence for augmentation on clozapine. Activation of N-methyl-D-aspartate receptors, including inhibition of D-amino acid oxidase that may metabolize D-amino acids, has been reported to be beneficial for patients receiving antipsychotics other than clozapine. This study aimed to examine the efficacy and safety of a D-amino acid oxidase inhibitor, sodium benzoate, for schizophrenia patients who had poor response to clozapine. METHODS We conducted a randomized, double-blind, placebo-controlled trial. Sixty schizophrenia inpatients that had been stabilized with clozapine were allocated into three groups for 6 weeks' add-on treatment of 1 g/day sodium benzoate, 2 g/day sodium benzoate, or placebo. The primary outcome measures were Positive and Negative Syndrome Scale (PANSS) total score, Scale for the Assessment of Negative Symptoms, Quality of Life Scale, and Global Assessment of Functioning. Side effects and cognitive functions were also measured. RESULTS Both doses of sodium benzoate produced better improvement than placebo in the Scale for the Assessment of Negative Symptoms. The 2 g/day sodium benzoate also produced better improvement than placebo in PANSS-total score, PANSS-positive score, and Quality of Life Scale. Sodium benzoate was well tolerated without evident side effects. The changes of catalase, an antioxidant, were different among the three groups and correlated with the improvement of PANSS-total score and PANSS-positive score in the sodium benzoate group. CONCLUSIONS Sodium benzoate adjuvant therapy improved symptomatology of patients with clozapine-resistant schizophrenia. Further studies are warranted to elucidate the optimal dose and treatment duration as well as the mechanisms of sodium benzoate for clozapine-resistant schizophrenia.

Abstract
Clozapine, a dibenzodiazepine developed in 1961, is a multireceptorial atypical antipsychotic approved for the treatment of resistant schizophrenia. Since its introduction, it has remained the drug of choice in treatment-resistant schizophrenia, despite a wide range of adverse effects, as it is a very effective drug in everyday clinical practice. However, clozapine is not considered as a top-of-the-line treatment because it may often be difficult for some patients to tolerate as some adverse effects can be particularly bothersome (i.e. sedation, weight gain, sialorrhea etc.) and it has some other potentially dangerous and life-threatening side effects (i.e. myocarditis, seizures, agranulocytosis or granulocytopenia, gastrointestinal hypomotility etc.). As poor treatment adherence in patients with resistant schizophrenia may increase the risk of a psychotic relapse, which may further lead to impaired social and cognitive functioning, psychiatric hospitalizations and increased treatment costs, clozapine adverse effects are a common reason for discontinuing this medication. Therefore, every effort should be made to monitor and minimize these adverse effects in order to improve their early detection and management. The aim of this paper is to briefly summarize and provide an update on major clozapine adverse effects, especially focusing on those that are severe and potentially life threatening, even if most of the latter are relatively uncommon.

Abstract
Abstract
Clozapine is the drug of choice for drug-resistant schizophrenia, but despite its use, 30-40% patients fail to achieve satisfactory therapeutic effects. In such situations, augmentation attempts are made by both pharmacological and non-pharmacological methods. To date, most of the work has been devoted to pharmacological strategies, much less to augemantation of clozapine with electroconvulsive therapy (C+ECT), transcranial direct current stimulation (tDCS) or transcranial magnetic stimulation (TMS).
Aim: The aim of the work is to present biological, non-pharmacological augmentation treatment methods with clozapine.
Material and methods: A review of the literature on non-pharmacological augmentation treatment methods with clozapine was made. PubMed database was searched using key words: drug-resistant schizophrenia, clozapine, ECT, transcranial magnetic stimulation, transcranial electrical stimulation and time descriptors: 1980-2017.
Results: Most studies on the possibility of increasing the efficacy of clozapine was devoted to combination therapy with clozapine + electric treatments. They have shown improved efficacy when using these two methods simultaneously from 37.5 to 100%. The only randomized trial so far has also confirmed the effectiveness of this procedure. Despite the described side effects of tachycardia or prolonged seizures, most studies indicate the safety and efficacy of combined use of clozapine and electroconvulsive therapy. Transcranial magnetic stimulation also appears to be a safe method in patients treated with clozapine. However, further research is needed before ECT can be included in standard TRS treatment algorithms. The data for combining transcranial electrical stimulation with clozapine, come only from descriptions of cases and need to be confirmed in controlled studies.
Conclusions: The results of studies on the possibility of increasing the effectiveness of clozapine using biological non-pharmacological treatment methods indicate a potentially beneficial effect of this type of methods in breaking the super-resistance in schizophrenia. Combination of clozapine and ECT can be considered as the most recommended strategy among these treatment methods.

Abstract
SummaryMany ethical dilemmas in medicine are associated with highly unusual clinical situations and are an almost daily challenge for mental health teams. We describe the ethical issues that arose in relation to a significant difference of opinion between team members about using nasogastric clozapine in the treatment of a severely ill patient. We discuss how conflicting emotions and perspectives within teams acquire ethical significance and how negotiation and reflection are essential for good-quality ethical reasoning to take place.Learning Objectives• Understand the different effects and importance of reasoning and emotions in moral decision-making• Use a clinical scenario involving a difficult and controversial procedure to explore the impact of social persuasion in moral decision-making• Consider the effects of heuristics against rational thinking

Abstract
Previous studies have suggested that a delay in initiating clozapine is one of the predictors of outcomes in treatment-resistant schizophrenia (TRS). However, whether there is a critical treatment window of clozapine in TRS and the duration of that window remain unclear. We conducted a secondary analysis of a previously published observational study using a retrospective chart review of 105 patients with TRS who were treated with clozapine. We included 90 patients who remained on clozapine for at least 3 months. The delay in initiating clozapine was an independent contributor to symptomatic improvement based on treatment with clozapine by multiple linear regression analysis. A receiver operating characteristic curve analysis (area under the curve: 0.78) confirmed 2.8 years was the best predictive cut-off value of delay in initiating clozapine for responses in patients treated with clozapine (sensitivity: 0.66, specificity: 0.84). In patients with a delay in initiating clozapine of ≤2.8 years and a delay in initiating clozapine of >2.8 years, the response rates were 81.6% and 30.8% (risk ratio=2.65; 95% confidence interval, 1.80, 3.63), respectively. Clinicians should reduce the delay in initiating clozapine to less than 3 years to improve symptomatic outcomes in TRS and to prevent clozapine-resistant schizophrenia.

Abstract
Acute agitation and aggression are common symptoms in patients with bipolar disorder and schizophrenia. In this review, we discuss the prevalence, clinical assessment strategies, treatment options, and current Western and Chinese guidelines for the management of acute agitation and aggression in patients with bipolar disorder or schizophrenia. Among available approaches, we discuss in detail recent evidence supporting the use of intramuscular (IM) antipsychotics and some recently approved oral atypical antipsychotics for the management of acute aggression and agitation in hospitalized patients with bipolar disorder or schizophrenia presenting with acute agitation or aggression, highlighting some differences between individual antipsychotic agents.

Abstract
BACKGROUND As a significant proportion of patients receiving palliative care suffer from states of anxiety, depression, delirium, or other mental symptoms, psychiatry and palliative care already collaborate closely in the palliative care of medical conditions. Despite this well-established involvement of psychiatrists in palliative care, psychiatry does not currently explicitly provide palliative care for patients with mental illness outside the context of terminal medical illness. DISCUSSION Based on the WHO definition of palliative care, a, a working definition of palliative psychiatry is proposed. Palliative psychiatry focuses on mental health rather than medical/physical issues. We propose that the beneficiaries of palliative psychiatry are patients with severe persistent mental illness, who are at risk of therapeutic neglect and/or overly aggressive care within current paradigms. These include long-term residential care patients with severe chronic schizophrenia and insufficient quality of life, those with therapy-refractory depressions and repeated suicide attempts, and those with severe long-standing therapy-refractory anorexia nervosa. An explicitly palliative approach within psychiatry has the potential to improve quality of care, person-centredness, outcomes, and autonomy for patients with severe persistent mental illness. CONCLUSIONS The first step towards a palliative psychiatry is to acknowledge those palliative approaches that already exist implicitly in psychiatry. Basic skills for a palliative psychiatry include communication of diagnosis and prognosis, symptom assessment and management, support for advance (mental health) care planning, assessment of caregiver needs, and referral to specialized services. Some of these may already be considered core skills of psychiatrists, but for a truly palliative approach they should be exercised guided by an awareness of the limited functional prognosis and lifespan of patients with severe persistent mental illness.

Abstract
OBJECTIVE We examined the time trends and correlates of clozapine use in schizophrenia patients in China. METHOD A total of 14,013 patients with schizophrenia treated in 45 psychiatric hospitals/centers nationwide were interviewed in 2002, 2006 and 2012. Patients' socio-demographic and clinical characteristics including psychopathology, medication side effects, satisfaction with treatment and quality of life (QOL) were recorded in a standardized fashion. RESULTS Clozapine was used in 32.9% of the whole sample; with corresponding figures of 39.7%, 32.5% and 26.4% in 2002, 2006 and 2012 (p<0.001). Families of clozapine users had lower satisfaction with treatment than those of the non-clozapine group, without significant differences with respect to patients' treatment satisfaction and mental or physical QOL. In multiple logistic regression analyses, compared to the non-clozapine group, patients on clozapine had an earlier age of onset, longer illness duration, more global illness severity and drug-induced central nervous system, gastrointestinal and other side effects, lower antipsychotic doses, less delusions and hallucinations, more negative symptoms, were more likely male, inpatients, to have a family history of psychiatric disorders, receive treatments in regional centers and receive antipsychotic polypharmacy, but less likely to have health insurance and receive first-generation antipsychotics and benzodiazepines (R(2)=0.498, p<0.001). CONCLUSIONS Clozapine was used in one-third of schizophrenia patients in China, with decreasing frequency since 2002. Patients prescribed clozapine had multiple markers of greater global illness severity/chronicity and decreased satisfaction with treatment by the families, but similar QOL and less delusions and hallucinations than patients not prescribed clozapine.
