Long-acting injectable (LAI) antipsychotics are important for improving adherence and preventing relapse. Risperidone in-situ microparticles (ISM), a once monthly LAI using ISM technology, rapidly achieves therapeutic plasma levels without loading doses or oral supplementation. Real-world evidence on its use remains limited. This multicenter observational-naturalistic-retrospective study assessed prescribing patterns of risperidone-ISM across nine Public Mental Health Departments in Lombardy, Italy. Data from 218 inpatients and outpatients with psychotic disorders diagnosed according to diagnostic and statistical manual of mental disorders, fifth edition, text revision criteria were collected. Demographic, clinical, and pharmacological variables were analyzed. Patients were stratified by dose (75 vs. 100 mg), and group differences were assessed using χ2 and analysis of variance tests. Multivariable logistic regression identified independent correlates of prescription of the 100 mg dose. Sample's mean age was 41.8 years (69% male), with 71.1% receiving 100 mg. LAI initiation was primarily intended to improve adherence in 77.7% of cases. Among hospitalized patients, Brief Psychiatric Rating Scale scores decreased between admission and discharge (59.35 vs. 33.48); however, causality could not be inferred. The 100 mg group had significantly more male patients and showed higher rates of substance use and involuntary hospitalization, while the 75 mg group more often presented depressive symptoms and antidepressant use. In multivariable analysis, only involuntary hospitalization remained independently associated with receiving the 100 mg dose. This study provides real-world evidence on prescribing patterns of different risperidone-ISM doses and short-term clinical outcomes among treated patients.

Although second-generation antipsychotics (SGAs) have proven to be effective therapeutic options for patients with schizophrenia, there is a notable lack of evidence on patients’ subjective perspectives regarding their well-being, quality of life, and satisfaction with these medications. This study aimed to evaluate the treatment satisfaction and effectiveness of lurasidone on quality of life and functioning in adult patients with schizophrenia in real-world Italian clinical practice. This was a multicentre, national, non-interventional, single-arm, 3-month prospective study. Patients who were naive to lurasidone treatment and whose treating physician had decided to start them on this medication were enrolled and evaluated over a 3-month period. Eligible patients were adults (≥ 18 years of age) with a primary diagnosis of schizophrenia who were being treated with lurasidone (for the first time [i.e., they were lurasidone naive]) as part of routine clinical practice. Efficacy endpoints were changes in patient/caregiver treatment satisfaction (seven-point Likert scale from the Treatment Satisfaction Questionnaire for Medication), patient quality of life and functioning (QLS), investigator-rated global assessment of functioning (CGI-S, IAQ) after 6 weeks and 3 months of lurasidone, and number of relapses and hospitalizations. Sixty-one patients were enrolled and 59 completed the study. The median dosage of lurasidone at baseline was 37.00 mg/day. The median duration of titration was 86.0 days (Min 28; Max 115 days); the median number of dosage changes was 1.0. At the end of 3-month observation period, the median dose of lurasidone was 74.00 mg/day. QoL and Functioning Score showed a trend of improvement over time, reaching a mean change from baseline of 9.8 at the end of the study. According to the CGI-S, the percentage of patients who were “markedly or severely ill” showed a continuous decrease from baseline to 3 months, from 62.29

From the deinstitutionalization of the second half of the twentieth century, the Mental Health Care System has focused on outpatient care and community-based services. The goal is reaching recovery in patients with severe mental illness, that means improving symptoms and allowing patients to develop their cognitive, emotional and social skills in order to live in the community. In this new scenario, psychosocial interventions find an important role in improving functioning in schizophrenia. Some psychosocial interventions based on multiple randomized controlled trials demonstrated to be effective at improving the outcome of schizophrenia, whereas others led to promising findings. In this chapter we will focus on evidence-based psychosocial practices to achieve recovery in schizophrenia, such as psychoeducation, cognitive behavioural therapy for psychosis, cognitive remediation and on interventions which led to potential benefits in this population, such as healthy lifestyle interventions, physical exercise and integrated treatments for co-occurring substance use disorder. Despite international guidelines recommend psychosocial interventions as supportive treatments alongside pharmaceutic or psychotherapeutic ones, until now only a minority of patients received a person-centred evidence-based psychiatric rehabilitation intervention. It is necessary to redesign services on the principles of recovery and to implement services that deliver interventions supported by scientific evidence.

The early and correct assessment of psychomotor agitation (PMA) is essential to ensure prompt intervention by healthcare professionals to improve the patient's condition, protect healthcare staff, and facilitate future management. Proper training for recognizing and managing agitation in all care settings is desirable to improve patient outcomes. The best approach is one that is ethical, non-invasive, and respectful of the patient's dignity. When deemed necessary, pharmacological interventions must be administered rapidly and avoid producing an excessive state of sedation, except in cases of severe and imminent danger to the patient or others. The purpose of this brief review is to raise awareness about best practices for the management of PMA in emergency care situations and consider the role of new pharmacological interventions in patients with agitation associated with bipolar disorder or schizophrenia.

Background: Many evidences have demonstrated the effectiveness of cognitive remediation on cognition and functioning in patients with schizophrenia. Some researchers speculate that cognitive deficits are more amenable to remediation during earlier phases of illness than in chronicity. Therefore, cognitive rehabilitation should be used as an early intervention, seeking to produce durable functional changes in the early course of schizophrenia. Although there is strong evidence that cognitive remediation is effective in adult schizophrenia, there is little evidence about its efficacy and long-term generalized effectiveness in the early course of the disease. In this paper, we intended to investigate the possibility that cognitive remediation may produce more beneficial effects when applied in the early phase of the illness compared to chronic patients. Materials and methods: Data were gathered from a database used for a previous study performed by our group, in which 56 patients with schizophrenia received a cognitive remediation intervention. In a post hoc analysis, patients with a duration of illness shorter than 5 years were defined as “early course” patients, while patients with a duration of illness longer than 5 years were defined as “chronic.” Clinical, neuropsychological, and functional outcome variables were assessed at baseline and after treatment. Result: Of the 56 patients included in the study, 11 were “early course” and 45 were “chronic.” Both the early course group and the chronic group showed significant improvements in all the clinical, neurocognitive, and functional parameters analyzed. A significantly greater improvement in early course patients compared with chronic patients emerged in clinical and functional measures. No differential change was observed between early course patients and chronic patients in the cognitive composite score. Conclusion: Our study confirms the effectiveness of cognitive remediation in improving clinical, cognitive, and functional parameters in patients with schizophrenia, both in patients in the early course and in chronic patients. However, patients in the early course showed a differential, greater change in clinical and functional parameters compared to chronic patients. Although this study has some limitations, it confirms the effectiveness of cognitive remediation interventions, particularly if applied in the early course of the illness.

Cognitive impairment is a central feature of schizophrenia and has shown to play a crucial role in the psychosocial function of the disorder. Over the past few years, several cognitive remediation (CR) interventions have been developed for schizophrenia, whose effectiveness has also been widely demonstrated by systematic reviews and meta-analysis studies. Despite these evidences, many questions remain open. In particular, the identi fi cation of CR response predictors in patients with schizophrenia is still a topic with equivocal fi ndings and only a few studies have looked for the relationship between CR response or resistance and the biological, socio-demographic, clinical and cognitive features in schizophrenia. The current knowledge on positive or negative response predictors to CR treatment in schizophrenia include: age, duration of illness, premorbid adjustment, baseline cognitive performance, intrinsic motivation, hostility, disorganized symptoms, neurobiological reserve, genetic polymorphisms, the amounts of antipsychotics, the type of CR, etc. The aim of this review is to identify neurobiological, psychopathological, cognitive, and functional predictors of CR response or resistance in schizophrenia, taking into account both cognitive and functional outcome measures. The information obtained could be very useful in planning integrated and personalized interventions, also with a better use of the available resources.

Objectives Integrated Psychological Therapy (IPT) is a group-based cognitive-behavior therapy program for schizophrenia that integrates cognitive and social cognitive remediation with psychosocial rehabilitation. IPT is based on the underlying assumption that basic deficits in cognitive functioning have a pervasive effect on higher levels of behavioral organization, including social skills and social and independent functioning. Meta-analytic studies underlined that IPT is an evidence-based rehabilitation approach for schizophrenia patients. The aim of this review was to discuss the feasibility and effectiveness in implementing IPT in everyday clinical practice in an Italian mental health service, among patients with schizophrenia and to identify the promoting strategies and the barriers against IPT implementation. Methods For these purpose, five studies published from 2011 to 2016 were included in the review, investigating the IPT cost-effectiveness ratio, compared with treatment as usual (TAU) in people with schizophrenia in a real-world psychiatric rehabilitative setting at the University Department of Mental Health of the Spedali Civili Hospital in Brescia (Italy). Results IPT was accepted by the majority proportion of schizophrenia patients and findings have shown promising improvement in clinical, cognitive and psychosocial functioning, persisting over time, after IPT intervention, with a favorable cost-effectiveness ratio. Conclusions In summary, our experience demonstrated that IPT could be effectively implemented as an integral component of psychosocial interventions and that it was accepted by a significant proportion of people with schizophrenia admitted to a medium-length-of-stay psychiatric rehabilitation setting. Participants who completed the cognitive training were observed to have significantly improved cognition and psychosocial functioning, whereas the groups who did not participate or discontinued the training did not demonstrate similar gains. Although these promising and encouraging results on IPT efficacy in real-world psychiatric rehabilitative setting, there is need for further translational research evaluating the effectiveness and applicability of cognitive remediation in everyday clinical practice.

BACKGROUND AND PURPOSE: Previous studies have suggested that structural changes do occur in the brain of patients with schizophrenia compared with healthy control participants. However, findings from such studies are inconclusive, probably because of the different methodologic approaches, the clinical heterogeneity of patient samples, and also the fact that patients enrolled were treated with antipsychotic drugs. The aim of this study was to investigate brain GM volumes and intrinsic structural WM changes in first-contact, antipsychotic drug-naïve patients with schizophrenia. MATERIALS AND METHODS: A total of 43 first-contact, drug-naïve, patients with schizophrenia and 17 age-matched control participants were studied. All participants underwent T1-weighted MR imaging and DTI scans. Voxel-based morphometry and tract-based spatial statistics were used to compare GM volumes and WM DTI metrics between groups. MR imaging measures were correlated with the duration of the untreated psychosis and the clinical positive and negative symptoms. RESULTS: Compared with control participants, patients with schizophrenia showed smaller volumes of the temporal, parietal, and occipital GM, and a pattern of decreased mean diffusivity and increased fractional anisotropy in the brain stem and cerebellum bilaterally, interhemispheric and cortico-cortical connections bilaterally, and right anterior and posterior limb of the internal capsule. In patients, decreased mean diffusivity and increased fractional anisotropy in several brain regions were related to a longer duration of the untreated psychosis and the severity of positive symptoms. CONCLUSIONS: First-contact, drug-naïve, patients with schizophrenia present with volumetric and DTI changes, which correlated with their clinical features. This study increases our knowledge on the neural networks involved in the pathophysiologic mechanisms of schizophrenia.

BACKGROUND:Recent studies supported associations between four NMDA-receptor-mediated signalling genes (D-amino acid oxidase, DAO; D-amino acid oxidase activator, DAOA; protein phosphatase 3 catalytic subunit gamma isoform, PPP3CC; dystrobrevin-binding protein 1, DTNBP1) and schizophrenia susceptibility, even though with contrasting results.METHODS:In an attempt to replicate these findings for the first time in an Italian population, a panel of 32 tagSNPs was analysed in a representative case-control sample involving 879 subjects.RESULTS:An association in the allele frequency was observed for the estimated PPP3CC CAG triplotype in the SNP window rs4872499 T/C-rs11780915 A/G-rs13271367 G/A (pcorrect = 0.001). Similarly, the clustered genotype frequencies of the estimated/phased CAG triplotype differed between cases and controls (p = 0.004), with the carriers having a higher frequency in the control population (p = 0.002, odd ratio OR = 0.59, 95% confident interval CI: 0.43-0.82).Following the phenotypic dissection strategy, the analysis of single SNPs evidenced a protective effect in males of rs11780915 and rs13271367 in PPP3CC gene (pcorrect = 0.02, pcorrect = 0.04 respectively). Moreover the estimated/phased GT diplotype (rs2070586A/G-rs3741775G/T) carriers of the DAO gene were more highly represented in female controls (p = 0.017, OR = 0.58, 95% CI: 0.37-0.90), as were the estimated/phased CAG triplotype carriers of the PPP3CC gene in females (p = 0.01, OR = 0.53, 95% CI: 0.32-0.87). In addition, we performed an interaction analysis, and a 66% (p = 0.003, OR = 0.34, 95% CI: 0.17-0.70) lower risk of developing schizophrenia for female (CAG + GT) carriers versus non-CAG or -GT carriers was observed. For DTNBP1, we found a protective effect in males for the rs6459409 (pcorrect = 0.02) and the estimated/phased CT diplotype (rs6459409-rs9476886) carriers (p = 3x10-4, OR = 0.46, 95% CI: 0.30-0.70).In relation to diagnostic subtypes, the estimated/phased DAO GT diplotype and PPP3CC CAG triplotype female carriers were found to show relative risk ratio (RRR) values of 0.52 and 0.54 lower risk for a paranoid phenotype respectively.CONCLUSIONS:Although the results are preliminary and needed replication in a larger sample, this study suggests that NMDA receptor-mediated signalling genes (DAO, PPP3CC, DTNBP1) might be involved in schizophrenia pathogenic mechanisms related to gender.

Ziprasidone, a benzisothiazolyl piperazine derivative of tiospirone, is a second-generation antipsychotic with high-affinity antagonism for 5-hydroxytryptophan (5HT)2A, 5HT2C, 5HT1D and D2 receptors, pre- and post-synaptic agonism for 5HT1A receptors, and inhibition of reuptake for serotonin and norepinephrine. Initially approved for the treatment of adults with schizophrenia, ziprasidone has more recently received supplementary indications for acute manic and mixed episodes and as maintenance therapy for people affected by bipolar disorder. Based on MEDLINE citations up to November 2010 and hand-searched references, this article relating to ziprasidone addresses its short- and long-term efficacy and safety, according to the results of randomized clinical trials, open-label studies and real-world experiences. Emerging evidence indicates that in patients with bipolar disorder, ziprasidone provides valid efficacy and remarkable safety when administered alone for the treatment of manic and mixed episodes. The same applies when ziprasidone is administered in combination with lithium or valproate for the prevention of affective relapses and recurrences. Any conclusion on the potential of ziprasidone as an antidepressant should be postponed because of insufficient evidence.

This 18-week, randomized, flexible-dose, double-blind, double-dummy trial evaluated ziprasidone as an alternative to clozapine in treatment-refractory schizophrenia patients. Patients had a DSM-IV diagnosis of schizophrenia, a history of resistance and/or intolerance to at least three acute cycles with different antipsychotics given at therapeutic doses, PANSS score >or= 80, and CGI-S score >or= 4. Patients were randomized to ziprasidone (80-160 mg/day, n = 73) or clozapine (250-600 mg/day, n = 74). On the primary ITT-LOCF analysis, baseline-to-endpoint decreases in PANSS total scores were similar in the ziprasidone (- 25.0 +/- 22.0, 95% CI - 30.2 to - 19.8) and clozapine (- 24.5 +/- 22.5, 95% CI - 29.7 to - 19.2) groups. A progressive and significant reduction from baseline in PANSS total score was observed from day 11 in both study arms. There were also significant improvements on PANSS subscales, CGI-S, CG-I, CDSS, and GAF, without between-drug differences. The two treatment groups had similar rates of early discontinuations due to AEs. AEs were mostly of similar mild-moderate severity in the two groups. There were also no detrimental effects on prolactin, renal and liver function, hematology, and cardiovascular parameters. However, ziprasidone but not clozapine showed a significant reduction of SAS and AIMS scores. Moreover, when compared with clozapine, ziprasidone also had a more favorable metabolic profile, with significant endpoint differences in weight, fasting glucose, total cholesterol, LDL cholesterol, and triglycerides. In conclusion, this trial indicates that both ziprasidone and clozapine, having comparable efficacy coupled with satisfactory general safety and tolerability, may be regarded as valuable options for the short-term treatment of difficult-to-treat schizophrenia patients with a history of multiple resistance and/or intolerance to antipsychotics. The more favorable metabolic profile of ziprasidone may represent an added value that could guide clinicians, at least in the presence of patients at high risk for metabolic disorders.

Background: Recent data have suggested few differences in the cognitive effects of antipsychotic medications. However, assessment of such effects can be complex, due to a number of factors. Clozapine has previously shown greater clinical and lesser cognitive benefits than other atypicals. This study compared the cognitive benefits of clozapine and ziprasidone in schizophrenia patients (n = 130) with a history of either failure to respond to or intolerance of previous adequate antipsychotic treatments.Methods: Patients were randomized (double-blind) to either clozapine or ziprasidone in a single country (Italy), multi-site trial. The cognitive assessments examined episodic memory (RAVLT), executive functioning (Stroop test), and processing speed (Trail-making test (TMT) Parts A and B).Results: Analyses found statistically significant within-group improvements for ziprasidone in learning and delayed recall on the RAVLT and on TMT Parts A and B. Clozapine-treated patients improved on the RAVLT, but not on the TMT. A composite cognitive score improved from baseline in both groups, but the improvements were significantly larger in the ziprasidone group (p=.029).Implications: These results indicated that cognitive functioning improved following treatment with ziprasidone in patients with a history of either treatment resistance or intolerance, and that the effects are comparable or greater than those observed with clozapine. One interpretation of these findings is that clozapine treatment interferes with the performance benefits associated with practice. (c) 2007 Elsevier B.V. All rights reserved.

Background: There is evidence of a link between schizophrenia and a deficit of working memory, but this has been derived from tasks not specifically developed to probe working memory per se. Our aim was to investigate whether working memory deficits may be detected across different paradigms using the self-ordered pointing task (SOPT) and the visual conditional associative learning task (VCALT) in patients with schizophrenia spectrum disorders and healthy controls. The current literature suggests deficits in schizophrenia spectrum disorder patients versus healthy controls but these studies frequently involved small samples, broad diagnostic criteria, inclusion of patients on antipsychotic medications, and were not controlled for symptom domains, severity of the disorder, etc. To overcome some of these limitations, we investigated the self-monitoring and conditional associative learning abilities of a numerically representative sample of healthy controls and a group of nondeteriorated, drug-free patients hospitalized for a schizophrenia spectrum disorder with florid, mainly positive psychotic symptoms.Methods: Eighty-five patients with a schizophrenia spectrum disorder (DSM-IV-TR diagnosis of schizophrenia (n = 71) or schizophreniform disorder ( n = 14)) and 80 healthy controls entered the study. The clinical picture was dominated by positive symptoms. The healthy control group had a negative personal and family history of schizophrenia or mood disorder and satisfied all the inclusion and exclusion criteria other than variables related to schizophrenia spectrum disorders.Results: Compared to controls, patients had worse performances on SOPT, VCALT and higher SOPT/VCALT ratios, not affected by demographic or clinical variables. ROC curves showed that SOPT, VCALT, and SOPT/VCALT ratio had good accuracy in discriminating patients from controls. The SOPT and VCALT scores were inter-correlated in controls but not in patients.Conclusion: The selection of a clinically homogeneous group of patients, controlled for a number of potential confounding factors, and the high level of significance found in the different analyses confirm the presence of SOPT and VCALT abnormalities in a large preponderance of patients with schizophrenia spectrum disorder with positive symptoms. SOPT, VCALT, and SOPT/VCALT ratio showed good accuracy in discriminating patients from healthy controls. These conclusions cannot be extended to schizophrenia spectrum disorder patients with a different clinical profile from our patient population.

Background: Corpus callosum is the most important commissure of the brain and therefore represents a first-choice candidate to challenge hypotheses of disrupted inter-hemispheric connectivity and white matter pathology in patients with schizophrenia. Recent studies oil diffusion tensor imaging (DTI) of corpus callosum yielded promising but equivocal evidence of reduced fractional anisotropy (FA) in schizophrenia patients who were, for the most part, chronic cases on medication for a lengthy period of time. To exclude potentially confounding effects of the course of the disorder and its treatment, we compared callosal FA of first-contact, antipsychotic drug-naive schizophrenia patients (n=21) and healthy controls (n=21).Methods: Splenium and genu FA were obtained by two independent observers utilizing large, rectangular, tractography-guided regions of interest outlined on directional color-coded maps. Inter-observer agreement on FA was evaluated by means of the Bland and Altman and the Passing and Bablok procedures together with an estimate of the intra-class correlation coefficient.Results: Strong inter-observer agreement of FA values emerged from each of the three statistical approaches utilized. ANCOVA showed a significant effect oil FA for the interaction between patient-control membership and callosal region (F=5.354; p=0.026); post hoc multiple comparisons demonstrated that, when compared to the controls, the patients had lower mean FA values (p=0.005) in the splenium but not in the genu and that this difference tended to be more evident in males (p=0.090).Conclusions: Lowered mean FA values in the splenium of first-con tact, antipsychotic drug-naive patients with respect to healthy controls strongly Support the hypothesis that processes operant at least since the earliest phases of the disorder and independent from exposition to antipsychotic drugs contribute to reduced anisotropy in schizophrenia.
