Abstract
Background Schizophrenia is a complex, chronic mental health disorder that confers a substantial disease burden globally. Oral antipsychotic treatments (OATs) are the mainstay for treating early and advanced stages of schizophrenia. Our systematic review aimed to synthesize literature describing real-world effectiveness, economic, and humanistic outcomes of OATs (asenapine, brexpiprazole, cariprazine, iloperidone, lumateperone, lurasidone, olanzapine/samidorphan, paliperidone, and quetiapine) for successful management of the disease. Methods PubMed, American Psychological Association PsycINFO (EBSCOhost), and Cumulative Index of Nursing and Allied Health Literature were searched according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies reporting real-world effectiveness, costs, humanistic, behavioral (eg, interpersonal relations, suicide ideation), medication adherence, and product-switching outcomes for selected OATs published in English from January 2010 to March 2022 were identified and evaluated qualitatively. Results We included 48 studies with different designs providing extensive evidence on schizophrenia. All studies were conducted in countries outside of the United States. In most studies, antipsychotic medications were more effective than placebo, suggesting their value in the management of schizophrenia. Sixteen studies measured the economic outcomes of OATs. Eight studies assessed humanistic outcomes, while one reported behavioral outcomes in three second-generation antipsychotics. Medication adherence was described in two studies, while five studies evaluated product switching. Non-adherence was commonly reported for OATs. Medication non-adherence and treatment discontinuation were predominant factors contributing to the economic burden of schizophrenia. Conclusion Our research showcased a significant knowledge gap across OATs spanning the humanistic and behavioral outcomes and medication adherence and switching, suggesting a need for robust evidence generation to help clinicians and payers make informed decisions regarding treatment opportunities and cost-effective strategies for patients with schizophrenia.

Long-acting injectable versus oral antipsychotics for the maintenance treatment of schizophrenia: a systematic review and comparative meta-analysis of randomised, cohort, and pre-post studies. Lancet Psychiatry 2021; 8:387-404. [PMID: 33862018 DOI: 10.1016/s2215-0366(21)00039-0] [Citation(s) in RCA: 172] [Impact Index Per Article: 57.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2020] [Revised: 01/25/2021] [Accepted: 01/25/2021] [Indexed: 12/15/2022]
Abstract
BACKGROUND Evidence of comparative benefits of long-acting injectable antipsychotics (LAIs) versus oral antipsychotics for schizophrenia has been inconsistent across study designs. The aim of this study was to evaluate the comparative benefits of LAIs versus oral antipsychotics in three study designs to inform clinical decision making. METHODS We did a comprehensive systematic review and meta-analysis comparing LAIs versus oral antipsychotics for schizophrenia covering three study designs: randomised controlled trials (RCTs), cohort studies, and pre-post studies. Our literature search was without language restrictions, in MEDLINE and PubMed, the Cochrane Library, Scopus, and Embase, for studies published from database inception up to a last search on March 13, 2020. We also searched for unpublished studies and ClinicalTrials.gov. We included studies lasting at least 6 months that targeted adults with schizophrenia and related disorders (>80% of participants). Studies on penfluridol (neither an LAI or daily oral antipsychotic), case reports, and case series with fewer than 20 patients were excluded. Two investigators independently extracted study-level data and resolved disagreement by consensus, or via a third investigator. Study authors were contacted to obtain additional information as needed. For our primary outcome we meta-analysed the risk ratio (RR) for hospitalisation or relapse with LAIs versus oral antipsychotics by a random-effects model, with hospitalisation used preferentially over relapse. As secondary analyses, we reversed the preferential order to relapse over hospitalisation, and assessed hospitalisation risk and relapse risk individually. Other secondary outcomes included all meta-analysable data, classed by relevance to effectiveness, efficacy, safety, quality of life, cognitive function, and other outcomes, and analysed by study design. Dichotomous outcomes were expressed as pooled RR and continuous outcomes as standardised mean difference (SMD). The protocol is registered with PROSPERO (CRD42019142094). FINDINGS We identified 14 687 records, of which 137 studies (397 319 patients) met the inclusion criteria (32 RCTs [23·4%; 8577 patients], 65 cohort studies [47·4%; 377 447 patients], and 40 pre-post studies [29·2%; 11 295 patients]) and were analysed. The quality of studies in terms of risk of bias varied across study designs and within each study design from low to high. LAIs were associated with a lower risk of hospitalisation or relapse than oral antipsychotics in each of the three study designs (RCTs: 29 studies, 7833 patients, RR 0·88 [95% CI 0·79-0·99], p=0·033; cohort studies: 44 studies, 106 136 patients, RR 0·92 [0·88-0·98], p=0·0044; pre-post studies: 28 studies, 17 876 patients, RR 0·44 [0·39-0·51], p<0·0001). This association was maintained across the study designs when we reversed the preferential order to risk of relapse over hospitalisation, and in individual analysis of hospitalisation risk. The association was maintained only in pre-post studies for relapse risk alone. In all other outcomes related to effectiveness, efficacy, safety, quality of life, cognitive function, and other outcomes, LAIs were more beneficial than oral antipsychotics in 60 (18·3%) of 328 comparisons, not different in 252 (76·8%) comparisons, and less beneficial in 16 (4·9%) comparisons when analysed by study design. Significant heterogeneity was observed across all three study designs. Publication biases were apparent in cohort and pre-post studies, but effect sizes were similar after trim-and-fill analyses. INTERPRETATION Although study designs have strengths and weaknesses, including potential low quality of observational studies, we consistently identified significant benefit with LAIs versus oral antipsychotics in preventing hospitalisation or relapse, in settings ranging from restricted research (RCTs) to real-word application (cohort and pre-post studies). Our findings suggest that increased clinical use of LAIs could improve outcomes in schizophrenia. FUNDING None.

Abstract
Introduction: In this review, the authors discuss the role of long-acting injectable antipsychotics (LAIs) for schizophrenia, focusing on the effectiveness and new perspectives introduced by such treatment strategy. Despite their promising pharmacokinetic features and their potential advantages in medication adherence, clinical outcomes, and medical costs, LAIs are not habitually presented as an option for patients, especially in the early phase of schizophrenia.Areas covered: This review explores the panorama of available LAIs for the treatment of schizophrenia, first-episode of psychosis, approved indications, medical costs, medication adherence, side effects, effectiveness and differences between first-generation (FGA)-LAIs and second-generation (SGA)-LAIs.Expert Opinion: LAIs differ in terms of specific indications, approved injection sites, needle size, injection volume, injection interval as well as potential drug-drug interactions, and commonly reported adverse reactions. The approved indications have expanded beyond schizophrenia to include bipolar and schizoaffective disorder. SGA-LAIs are often preferred to FGA-LAIs. FGA-LAIs although are less chosen in new patients due to the induction of cognitive and extrapyramidal side effects, even if, on the other hand, many SGA-LAIs are burden by hyperprolactinemia and weight gain. After a review of the available evidence, insight is provided into the potential and current therapeutic opportunities offered by LAI antipsychotic formulations.

Abstract
OBJECTIVE Obesity and adverse metabolic outcomes in patients with severe mental illness are clinically significant but potentially preventable. Importantly, the evidence for switching to antipsychotics to reduce cardiometabolic burden is unclear. METHOD PubMED, Embase, PsycINFO, and Cochrane were searched from inception to March 8, 2020. Articles reporting weight and metabolic changes after antipsychotic switching vs staying on the previous antipsychotic were meta-analyzed both across and within group. RESULTS Of 61 identified studies, 59 were meta-analyzed (40% rated high quality). In the switch-vs-stay pairwise meta-analyses, only aripiprazole significantly reduced weight (-5.52 kg, 95% CI -10.63, -0.42, P = .03), while olanzapine significantly increased weight (2.46 kg, 95% CI 0.34, 4.57, P = .02). Switching to aripiprazole also significantly improved fasting glucose (-3.99 mg/dl, 95% CI -7.34, -0.64, P = .02) and triglycerides (-31.03 mg/dl, 95% CI -48.73, -13.34, P = .0001). Dropout and psychosis ratings did not differ between switch and stay groups for aripiprazole and olanzapine. In before-to-after switch meta-analyses, aripiprazole (-1.96 kg, 95% CI -3.07, -0.85, P < .001) and ziprasidone (-2.22 kg, 95% CI -3.84, -0.60, P = .007) were associated with weight loss, whereas olanzapine (2.71 kg, 95% CI 1.87, 3.55, P < .001), and clozapine (2.80 kg, 95% CI 0.26, 5.34, P = .03) were associated with weight gain. No significant weight or other cardiometabolic changes were observed when switching to amisulpride, paliperidone/risperidone, quetiapine, or lurasidone. CONCLUSIONS Switching antipsychotics to agents with lower weight gain potential, notably to aripiprazole and ziprasidone, can improve weight profile and other cardiometabolic outcomes. When choosing switch agents, both the weight gain potential of the pre- and post-switch antipsychotic must be considered. Antipsychotic switching in psychiatrically stable patients must be weighed against the risk of psychiatric worsening.

Abstract
OBJECTIVE Previous research shows that patients with schizophrenia have increased cardiovascular disease risk than general population. Increased cardiovascular risk in schizophrenia patients have been associated with many reasons such as antipsychotic drugs, genetic predisposition, andlifestyle. In this study, we aimed to investigate the relationship between the risk of heart disease and schizophrenia symptomatology. METHODS The 10-year cardiovascular risk was assessed by the Framingham Risk Score (FRS) in 103 patients with schizophrenia and in 39 healthy controls. Sociodemographic characteristics, age at schizophrenia onset, duration of illness, number of hospitalizations, the course of the disease and antipsychotic medications were recorded. Patients' symptoms were evaluated via The Scale for the Assessment of Negative Symptoms (SANS), The Scale for the Assessment of Positive Symptoms (SAPS), and Calgary Depression Scale for Schizophrenia (CDSS). RESULTS Ten-year cardiovascular risk was 5.16% inpatients with schizophrenia, and 3.02% in control group (p=0.030). No significant correlation was found between FRS scores, SANS, SAPS, and CDSS scores. However, FRS scores were significantly correlated with age, number of hospitalizations and duration of disease (r=0.300, 0.261, 0.252, respectively). Moreover FRS scores were higher (p=0.008) and high-density lipoprotein (HDL) levels were lower (p=0.048) in patients using multiple antipsychotics. CONCLUSION Our findings suggest a relationship between the risk of cardiovascular disease and the duration and overall severity of schizophrenia and also highlights the role of antipsychotics in this relationship.

Abstract
Schizophrenia is a chronic syndrome involving different clinical dimensions, and causes significant disability with a negative impact on the quality of life of patients and their caregivers. Current guidelines for the treatment of schizophrenia focus on maximizing a patient's adaptive functioning and quality of life in a recovery-oriented approach that encourages active collaboration among patients, caregivers, and mental health professionals to design and manage a customized and comprehensive care plan. In the present study, a panel of experts (psychiatrists, psychologists, nurse, and social worker) gathered to review and explore the need for contemporary use of second-generation antipsychotic long-acting injectables (SGA LAIs) in "recovery-oriented" and "patient-centered" care of schizophrenia. Starting from the available data and from sharing personal attitudes and experiences, the panel selected three clinical dimensions considered useful in characterizing each patient: phase of disease, adherence to treatment, and level of functioning. For each clinical dimension, perspectives of patients and caregivers with regard to needs, expectations, and personal experiences were reviewed and the role of SGA LAIs in achieving shared goals examined. The experts concluded that from today's modern perspectives, SGA-LAIs may play an important role in breaking the spiral of desocialization and functional decline in schizophrenia, thus favoring the recovery process.

Abstract
AbstractBackground:To present real-world evidence on the effects of switching from oral to long-acting injectable (LAI) antipsychotic maintenance treatment (AMT) in a sample of clinically stable patients with schizophrenia, with regard to subjective experience of treatment, attitude towards drug and quality of life.Methods:50 clinically stable adult schizophrenic outpatients were recruited. At the time of enrolment (T0), all patients were under a stabilized therapy with a single oral second-generation antipsychotic (SGA) and were switched to the equivalent maintenance regimen with the long-acting formulation of the same antipsychotic. 43 patients completed the 24-month prospective, longitudinal, open-label, observational study. Participants were assessed at baseline (T0), after 12 (T1) and 24 months (T2), using psychometric scales (PANSS, YMRS and MDRS) and patient-reported outcome measures (SWN-K, DAI-10 and SF-36).Results:The switch to LAI-AMT was associated with a significant clinical improvement at T1 and T2 compared to baseline (T0). All of the psychometric indexes, as well as patients’ subjective experience of treatment (SWN-K), and quality of life (SF-36) showed a significant improvement after one year of LAI-AMT, with stable results after two years. Patients’ attitude towards drug (DAI-10) increased throughout the follow-up period, with a further improvement during the second year.Conclusions:The switch to LAI-AMT may help to address the subjective core of an optimal recovery in stabilized schizophrenic patients. A sustained improvement in patients’ attitude towards drug may help to achieve patient’s compliance. The size of this study needs to be expanded to produce more solid and generalizable results.

Abstract
RATIONALE Long-acting injectable antipsychotic therapies may offer benefits over oral antipsychotics in patients with schizophrenia. OBJECTIVE This study aimed to explore the safety, tolerability, and treatment response of paliperidone palmitate once-monthly in non-acute but symptomatic adult patients switched from previously unsuccessful monotherapy with frequently used oral atypical antipsychotics. METHODS This was a post hoc analysis of a prospective, interventional, single-arm, international, multicenter, open-label, 6-month study. RESULTS The patients (N = 472) were switched to paliperidone palmitate once-monthly (PP1M) from daily oral treatment with either aripiprazole (n = 46), olanzapine (n = 87), paliperidone extended-release (n = 104), quetiapine (n = 44), or risperidone (n = 191). In all groups, mean Positive and Negative Syndrome Scale total (p < 0.0001) and Clinical Global Impression-Severity scores improved significantly (p = 0.0004 to p < 0.0001). An improvement of ≥50 % in the Positive and Negative Syndrome Scale total score was observed in 21.7 % (aripiprazole), 29.9 % (olanzapine), 29.8 % (paliperidone extended-release), 27.3 % (quetiapine), and 37.2 % (risperidone) of patients. The patients showed significant improvements in the Personal and Social Performance score (aripiprazole p = 0.0409, all others p ≤ 0.0015); Mini International Classification of Functionality, Disability and Health Rating for Activity and Participation Disorders in Psychological Illnesses total scores (all p < 0.01); and Treatment Satisfaction Questionnaire for Medication Global Satisfaction score (olanzapine and risperidone p < 0.0001, quetiapine p = 0.0465, paliperidone extended-release p = 0.0571, aripiprazole p = NS). Paliperidone palmitate once-monthly was well tolerated, presenting no new safety signals. CONCLUSIONS These data illustrate that stable, non-acute but symptomatic patients on oral antipsychotic monotherapy may show clinically meaningful improvement of symptoms, functioning, and treatment satisfaction after direct transition to PP1M. The findings are limited by the naturalistic study design; thus, further studies are required to confirm the current findings.

Abstract
Schizophrenia presents unique difficulties in clinical trial design associated with the condition's variable presentation and clinical course, and multiple features influencing affect, cognition, volition and perception. Randomized controlled trials (RCTs) are explanatory studies using a carefully selected patient population, predefined assessment intervals and, generally, symptom-focused endpoints. Naturalistic studies are pragmatic, with no active intervention, and outcomes that are generally those used in clinical practice (e.g. hospitalization, relapse rate). Both naturalistic studies and RCTs have pros and cons, making it difficult for physicians in clinical practice to apply research findings to their own treatment decisions. The choice of clinical trial design can have a significant impact on the comparative effectiveness or efficacy of drugs. This is particularly true for studies comparing long-acting injectable (LAI) antipsychotics with oral antipsychotics in schizophrenia, in which RCTs generally show no benefit for LAIs over oral drugs, whereas observational studies do. The more pragmatic the study design, the more likely it is to show a benefit for LAIs versus oral therapy. This article reviews the pros and cons of different study types, using published examples. Criteria are outlined to help physicians design appropriate prospective studies in schizophrenia including the relevant pragmatic and/or explanatory features, as required.

Abstract
OBJECTIVE To assess the effects of aripiprazole once-monthly 400 mg (AOM 400) on clinical symptoms and global improvement in schizophrenia after switching from an oral antipsychotic. METHODS In a multicenter, open-label, mirror-image, naturalistic study in patients with schizophrenia (>1 year, Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision [DSM-IV-TR] criteria), changes in efficacy measures were assessed during prospective treatment (6 months) with AOM 400 after switching from standard-of-care oral antipsychotics. During prospective treatment, patients were cross-titrated to oral aripiprazole monotherapy (1-4) weeks followed by open-label AOM 400 (24 weeks). Mean change from baseline of the open-label AOM 400 phase in Positive and Negative Syndrome Scale (PANSS) scores (total, positive and negative subscales) and Clinical Global Impression-Severity (CGI-S) scores; mean CGI-Improvement (CGI-I) score; and proportion of responders (≥30% decrease from baseline in PANSS total score or CGI-I score of 1 [very much improved] or 2 [much improved]) were assessed. RESULTS PANSS and CGI-S scores improved from baseline (P<0.0001) and CGI-I demonstrated improvement at all time points. By the end of the study, 49.0% of patients were PANSS or CGI-I responders. CONCLUSIONS In a community setting, patients with schizophrenia who were stabilized at baseline and switched to AOM 400 from oral antipsychotics showed clear improvements in clinical symptoms.

LAI versus oral: A case-control study on subjective experience of antipsychotic maintenance treatment. Eur Psychiatry 2016; 37:35-42. [PMID: 27442981 DOI: 10.1016/j.eurpsy.2016.05.008] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2016] [Revised: 04/05/2016] [Accepted: 05/13/2016] [Indexed: 01/12/2023] Open
Abstract
BACKGROUND To present real-world evidence on the differences between long-acting injectable (LAI) and oral antipsychotic maintenance treatment (AMT) in terms of subjective well-being, attitudes towards drug and quality of life in a sample of remitted schizophrenic subjects. METHODS Twenty outpatients with remitted schizophrenia treated with either olanzapine or paliperidone and switching from the oral to the LAI formulation of their maintenance treatment were recruited before the switch (LAI-AMT group). A group of 20 remitted schizophrenic subjects with oral AMT and matching main sociodemographic, clinical and treatment variables made up the control group (oral-AMT group). All participants were assessed in terms of objective (PANSS, YMRS, MADRS) and subjective (SWN-K, DAI-10, SF-36) treatment outcomes at baseline (T0) and after 6 months (T1). RESULTS Between T0 and T1, general psychopathology of the PANSS, DAI-10, and all but one of the SWN-K dimensions (except for social integration), showed significantly higher percentages of improvement in the LAI-AMT group compared to the oral-AMT group. A generalized expansion of health-related quality of life, with better functioning in almost all areas of daily living, was reported by the LAI-AMT group after the 6-month period. In contrast, the oral-AMT group reported a significant worsening of health-related quality of life in the areas of emotional role and social functioning in the same period. CONCLUSIONS Our study indicates possible advantages of LAI over oral antipsychotic formulation in terms of subjective experience of maintenance treatment in remitted schizophrenic patients. Size and duration of this study need to be expanded in order to produce more solid and generalizable results.

Schizophrenia-spectrum patients treated with long-acting injectable risperidone in real-life clinical settings: functional recovery in remitted versus stable, non-remitted patients (the EVeREST prospective observational cohort study). BMC Psychiatry 2016; 16:8. [PMID: 26772753 PMCID: PMC4714464 DOI: 10.1186/s12888-016-0712-1] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2015] [Accepted: 01/08/2016] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Previous studies showed functional improvement in stable patients with schizophrenia treated with risperidone long-acting injection (LAI). We therefore re-investigated functional improvement with risperidone LAI in remitted patients, in comparison with stable patients. The study was conducted in real-life conditions because of the high heterogeneity of the patients' situations. METHOD This was a multi-centre, prospective observational cohort study involving adult schizophrenia-spectrum chronic patients who were previously treated with risperidone LAI for 6 months. Remission was evaluated using the consensus criteria proposed by the Remission in Schizophrenia Working Group (RSWG). The primary endpoint was global functioning (assessed with the Global Assessment of Functioning scale, GAF) after one year of treatment. Social functioning was a secondary outcome. RESULTS The analysis included 1490 patients. Attrition rate was 9.1 % at the end of the study. 27.7 % of patients were in remission after one year of risperidone LAI treatment. The mean GAF rating score (62.5 ± 1.5) was higher than the cut-off previously used to identify patients with satisfactory functioning (60) and significantly higher than the mean GAF score in stable, non-remitted patients (48.3, p < 0.001). Social functioning was also high in remitted patients (21.0 ± 3.6 vs. 17.2 ± 3.7 in non-remitted patients, p < 0.001). CONCLUSION The results clearly show that after one year of treatment with risperidone LAI, RSWG-remitted patients have a high level of global functioning, which is significantly higher than in stable, non-remitted patients. Social functioning was also higher in remitted patients as compared with stable, non-remitted patients.

Abstract
BACKGROUND The challenges of comparative effectiveness to support health technology assessment (HTA) agencies are important considerations in the choices of antipsychotic medications for the treatment of schizophrenia. OBJECTIVES Our aim was to assess the study methods used and outcomes reported in the published literature to address the question of comparative effectiveness of newer antipsychotic agents and the adequacy and availability of evidence to support HTA agencies. DATA SOURCE A systematic search of the PubMed database from 1 January 2009 to 30 September 2013 was conducted to identify studies evaluating new atypical antipsychotics reporting on comparative effectiveness. STUDY SELECTION The systematic review comprised of studies on schizophrenia patients where at least two drugs were being compared and at least one treatment group received one of the following second-generation antipsychotics: risperidone, olanzapine, aripiprazole, paliperidone, asenapine, iloperidone, lurasidone, and quetiapine. The included studies were also required to have an efficacy, safety or economic outcome, such as Positive and Negative Syndrome Scale (PANSS) score, weight gain, resource utilization, or costs. STUDY APPRAISAL AND SYNTHESIS METHODS Two reviewers (BW and GK) independently applied the inclusion criteria. Disagreements between reviewers were resolved by consensus, referring to the original sources. Information on the methodology and outcomes was collected for each included study. This included study description, head-to-head drug comparison, patient population, study methodology, statistical methods, reported outcomes, study support, and journal type. RESULTS A total of 198 studies were identified from electronic search methods. The largest category of studies was randomized controlled trials [RCTs] (N = 73; 36.9%), which were largely directed at the regulatory endpoint. Fewer studies were undertaken for HTA-purposes cohort studies (N = 53; 26.8%), meta-analyses (N = 32; 16.2%), economic studies (N = 14; 7.1%), and cross-sectional studies (N = 13; 6.6%). Direct head-to-head comparisons preferred by HTA were dominated by the comparison involving olanzapine and risperidone, representing 149 (75.3%) and 119 (60.1%) studies, respectively. RCTs, which are the primary study type for regulatory submissions, showed a lack of bias. Studies aimed at HTA were not as well performed. Cohort studies suffered from bias in the selection of comparison groups, lack of control for confounders, and differential dropout rates. As a group, cross-sectional studies scored poorly for bias, with a primary failure to identify a representative sample. Economic studies showed highly variable bias, with bias in the representation of effectiveness data, model assumptions without validation, and lack of sensitivity analyses. LIMITATIONS One limitation of this systematic review is that it only included studies from 2009 to 2013, potentially excluding some earlier comparator studies, particularly those involving first-generation antipsychotics. CONCLUSIONS This review of comparative effectiveness studies of second-generation antipsychotic agents for schizophrenic patients revealed a wide range of study types, study methodologies, and outcomes. For traditional efficacy outcomes and select safety outcomes, there is strong evidence from many well-conducted studies; however, there are fewer studies of types preferred by HTA with limited head-to-head comparisons and a higher risk of bias in the execution of these studies.

Abstract
OBJECTIVE To present real-world preliminary evidence on the specific effects of switching from oral to long-acting injectable (LAI) antipsychotic treatment on patient's subjective experience and quality of life (QoL) in a sample of clinically stable psychotic subjects. METHODS Twenty-six clinically stable adult schizophrenic and schizoaffective outpatients were recruited. All patients were under a stabilized therapy with a single oral second-generation antipsychotic and were switched to the equivalent maintenance regimen with the long-acting formulation of the same antipsychotic. Two subgroups of patients were created on the basis of the presence/absence of a complete clinical remission at enrollment. Anthropometric (body mass index), psychometric (Montgomery-Asberg Depression Rating Scale, Young Mania Rating Scale, and Positive And Negative Syndrome Scale), and patient's reported outcome (Subjective Well-Being Under Neuroleptics scale short form, Drug Attitude Inventory short version, and Short Form-36 health survey) data were collected at enrollment (T0) and after 6 months from the treatment switch (T1). RESULTS Significant improvements in psychometric indexes, and patients' subjective experience of treatment and attitudes toward drug (reflecting in an enrichment of patients' health-related QoL) were found both in initial remitters and non-remitters. CONCLUSIONS Our preliminary results suggest that the switch from oral to LAI antipsychotic treatment may help to address the subjective core of an optimal and satisfying recovery of psychotic patients. Size and duration of this study need to be expanded in order to produce more solid and generalizable results.

Abstract
BACKGROUND Most women with psychotic disorders and bipolar disorders have children but their pregnancies are at risk of adverse psychiatric and fetal outcome. The extent of modifiable risk factors - both clinical and socio-demographic - is unclear as most studies have used administrative data or recruited from specialist tertiary referral clinics. We therefore aimed to investigate the socio-demographic and clinical characteristics of an epidemiologically representative cohort of pregnant women with affective and non-affective severe mental illness. METHODS Women with severe mental illness were identified from a large electronic mental health case register in south London, and a data linkage with national maternity Hospital Episode Statistics identified pregnancies in 2007-2011. Data were extracted using structured fields, text searching and natural language processing applications. RESULTS Of 456 pregnant women identified, 236 (51.7%) had schizophrenia and related disorders, 220 (48.3%) had affective psychosis or bipolar disorder. Women with schizophrenia and related disorders were younger, less likely to have a partner in pregnancy, more likely to be black, to smoke or misuse substances and had significantly more time in the two years before pregnancy in acute care (inpatient or intensive home treatment) compared with women with affective disorders. Both groups had high levels of domestic abuse in pregnancy (recorded in 18.9%), were from relatively deprived backgrounds and had impaired functioning measured by the Health of the Nation Outcome Scale. Women in the affective group were more likely to stop medication in the first trimester (39% versus 25%) whereas women with non-affective psychoses were more likely to switch medication. CONCLUSIONS A significant proportion of women, particularly those with non-affective psychoses, have modifiable risk factors requiring tailored care to optimize pregnancy outcomes. Mental health professionals need to be mindful of the possibility of pregnancy in women of childbearing age and prescribe and address modifiable risk factors accordingly.

A prospective flexible-dose study of paliperidone palmitate in nonacute but symptomatic patients with schizophrenia previously unsuccessfully treated with oral antipsychotic agents. Clin Ther 2014; 36:1372-88.e1. [PMID: 25444566 DOI: 10.1016/j.clinthera.2014.08.014] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2014] [Revised: 07/18/2014] [Accepted: 08/09/2014] [Indexed: 11/23/2022]
Abstract
PURPOSE The goal of this study was to explore the tolerability, safety, and treatment response of flexible doses of once-monthly paliperidone palmitate (PP) in the subset of nonacute but symptomatic adult patients with schizophrenia previously unsuccessfully treated with oral antipsychotic agents in the PALMFlexS (Paliperidone Palmitate Flexible Dosing in Schizophrenia) study. METHODS This was an interventional, single-arm, international, multicenter, unblinded, 6-month study performed in patients with schizophrenia. Patients were categorized according to reasons for switching. In patients switching because of lack of efficacy or for other reasons, primary efficacy outcomes were the proportion achieving treatment response (defined as ≥20% improvement in Positive and Negative Syndrome Scale [PANSS] total score from baseline to last-observation-carried-forward end point) and maintained efficacy (defined as noninferiority in the change in PANSS total score at end point versus baseline [Schuirmann's test]), respectively. FINDINGS A total of 593 patients (intention-to-treat population) were enrolled: 63.1% were male; their mean (SD) age was 38.4 (11.8) years; and 78.6% had paranoid schizophrenia. The main reasons for transition to PP were patient's wish (n = 259 [43.7%]), lack of efficacy (n = 144 [24.3%]), lack of compliance (n = 138 [23.3%]), and lack of tolerability (n = 52 [8.8%]) with the previous oral antipsychotic medication. The recommended PP initiation regimen (150 milligram equivalents [mg eq] day 1 and 100 mg eq day 8) was administered in 93.9% of patients. Mean PANSS total score decreased from 71.5 (14.6) at baseline to 59.7 (18.1) at end point (mean change, -11.7 [15.9]; 95% CI, -13.0 to -10.5; P < 0.0001). Sixty-four percent of patients showed an improvement of ≥20% in PANSS total score, and the percentage of patients rated mildly ill or less in Clinical Global Impression-Severity increased from 31.8% to 63.2%. Mean personal and social performance total score (SD) increased (ie, improved) significantly for all patients from baseline to end point (58.1 [13.4] to 66.1 [15.7]; P < 0.0001). IMPLICATIONS The PALMFlexS study is a pragmatic interventional study compared with randomized controlled trials, conducted in a large, more representative sample of patients with schizophrenia, and designed specifically to mimic real-world clinical situations. The findings support the results from randomized controlled studies. They also demonstrate that a clinically relevant treatment response is possible in patients who are considered to be clinically stable by their physician, supporting the use of flexibly dosed PP in such patients.

Abstract
OBJECTIVE Safety and tolerability assessment of initiating treatment with a once monthly long-acting injectable form of aripiprazole (aripiprazole once monthly) in patients stabilized on oral antipsychotics other than aripiprazole. METHODS Patients with schizophrenia treated with oral atypical antipsychotics other than aripiprazole and with a history of aripiprazole tolerability were enrolled. Patients were stabilized per investigator's judgment for ≥14 days on oral atypical antipsychotics during screening. Patients then received one dose of aripiprazole once monthly (400 mg). Concomitant with aripiprazole once monthly, subjects received their current oral atypical antipsychotic for 14 ± 1 days at doses reduced to the mid/lower recommended dose range. Safety and tolerability were assessed for the 28-day treatment phase. For pharmacokinetic analyses, aripiprazole plasma concentrations were measured on Days 7, 14, and 28. RESULTS Sixty patients were enrolled and initiated with aripiprazole once monthly while continuing treatment with oral olanzapine (n = 3), quetiapine (n = 28), risperidone (n = 24) or ziprasidone (n = 5). Duration of co-administered oral antipsychotic treatment varied, ranging from 0 to 15 days. Treatment was well tolerated. Frequently reported treatment-emergent adverse events (TEAEs) were injection-site pain and toothache (4/60 subjects each, 6.7%), followed by dystonia, fatigue, increased blood creatine phosphokinase, insomnia and restlessness (3/60 subjects each, 5.0%). Most TEAEs occurred in the first 8 days of co-administration irrespective of days of oral overlap. No clinically relevant mean changes from baseline were observed for laboratory values or fasting metabolic parameters. Psychotic symptoms remained stable. Aripiprazole plasma concentrations were similar to those observed following daily doses of oral aripiprazole. CONCLUSIONS The adverse-event profile of patients receiving aripiprazole once monthly concomitant with oral atypical antipsychotics other than aripiprazole was consistent with previous reports of aripiprazole once monthly concomitant with oral aripiprazole. Adverse events were similar irrespective of prior atypical antipsychotic and duration of oral antipsychotic overlap, suggesting that patients can be safely switched from their existing oral antipsychotic to aripiprazole once monthly without requiring an intermediate stabilization phase with oral aripiprazole. Aspects of the study design (open-label trial and short duration) and patient population (predominantly male and of African-American ethnicity) may limit the generalizability of these findings.

Abstract
Objective The objective of this work was to compare two generic questionnaires assessing patients’ satisfaction with medication. In addition we tested whether satisfaction can predict adherence to medication regimens in patients with chronic diseases, and which dimensions of satisfaction are most involved. Methods This prospective, observational study was conducted over one year in a heterogeneous population of patients with various chronic diseases. Satisfaction with medication was assessed by using the TSQM® vII and the SatMed-Q® questionnaires, and adherence to treatment was assessed with the Morisky-Green questionnaire. Clinical pharmacists interviewed patients to collect clinical, demographic and therapeutic data. Results 190 patients were enrolled. Both questionnaires showed excellent reliability and correlation was high (R = 0.70; p<0.001). Adherence was correlated with satisfaction with medication whether assessed with the SatMed-Q® (R = 0.23; p = 0.002) or the TSQM® (R = 0.17; p = 0.02). Among different dimensions of satisfaction, convenience of use and side effects are prominent predictors of adherence. Conclusion Adherence is related to the patient’s satisfaction with medication whether assessed with the TSQM® vII or the SatMed-Q®. Therefore, these simple questionnaires could be used as predictive tools to identify patients whos’ adherence needs to be improved.
