Rancans E, Dombi ZB, Mátrai P, Barabássy Á, Sebe B, Skrivele I, Németh G. The effectiveness and safety of cariprazine in schizophrenia patients with negative symptoms and insufficient effectiveness of previous antipsychotic therapy: an observational study. Int Clin Psychopharmacol 2021; 36:154-161. [PMID: 33560040 PMCID: PMC8011502 DOI: 10.1097/yic.0000000000000351] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/19/2020] [Accepted: 01/13/2021] [Indexed: 11/26/2022]
Abstract
The aim of the study was to examine the effectiveness and safety of cariprazine in routine psychiatric settings on schizophrenia patients with negative symptoms who have been treated with antipsychotics previously but without sufficient success. This was an open-label, flexible-dose, 16-week, observational study in Latvia. The primary outcome measure was an array of anamnesis-based clinical questions on schizophrenia symptoms rated on a seven-point scale. Other outcome measurements were the clinical global impression improvement (CGI-I) and severity (CGI-S) scales. Safety parameters included spontaneous reports of adverse events and specific assessments of extrapyramidal side-effects. A mixed model for repeated measures was fit to the data to evaluate the mean change from baseline for all visits. A total of 116 patients enrolled in the study (completion: 83%). Change from baseline to termination in symptom control was statistically significant (-7.3; P < 0.001), with the most improvement in negative symptoms (-6.3; P < 0.001). Over 70% of patients improved minimally or much based on the CGI-I scores at the final visit, and the CGI-S scores indicated an overall improvement in severity from moderately to mildly ill. 40% of patients experienced treatment-emergent adverse events. Over 70% of doctors were satisfied with the effectiveness and tolerability of cariprazine. Cariprazine significantly improved negative symptoms in schizophrenia patients.

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

Abstract
BACKGROUND Introduction of second-generation antipsychotics (SGAs) has reduced neurologic toxicity but are associated with increased weight gain and obesity. The objective of this pilot study is to compare the effects of first-generation antipsychotics (FGAs) and SGAs in patients with schizophrenia on body fat and presumed concomitant metabolic parameters. METHODS Study compared schizophrenia nondiabetic men treated with FGAs (group 1, n = 5) and men treated with SGAs (group 2, n = 9). Each subject completed psychiatric and endocrine evaluation including severity of psychiatric symptoms, adverse effects, body weight, body composition, and measurements of glucose, insulin, adipokines, and inflammatory markers. Student t test was used for statistical analysis. RESULTS Men treated with FGAs had a lower mean body mass index with a trend toward statistical significance (25.3 ± 1.4 vs 29.3 ± 1.7, P = 0.06). Treatment with FGAs was associated with lower waist/height ratio (0.55 ± 0.02 vs 0.62 ± 0.02, P = 0.036) and android fat mass index (0.62 ± 0.01 vs 0.96 ± 0.1, P = 0.03). Homeostasis Model Assessment for insulin resistance values were suggestive of significantly lower peripheral insulin resistance in men treated with FGAs (0.92 ± 0.15 vs 2.3 ± 0.34, P = 0.014). CONCLUSIONS The results of this study are significant for decreased peripheral insulin resistance in men treated with SGAs in a setting of no significant age difference and only a trend toward higher body mass index, but consistent documentation of increased abdominal fat by 3 different methodologies. Future studies involving larger number of subjects are warranted to verify the present findings.

Abstract
OBJECTIVES Cardiovascular diseases are the most common causes of premature death in patients with schizophrenia. We aimed at reducing cardiovascular risk factors in non-selected outpatients with schizophrenia using methods proven effective in short-term trials. Furthermore, we examined whether any baseline characteristics were associated with positive outcomes. METHODS All outpatients treated for schizophrenia at two Danish hospitals were included in this 1-year follow-up study. The patients were offered health interventions both individually and in groups. Weight, waist circumference, blood glucose and lipids and information on smoking and alcohol were obtained. RESULTS On average, small significant increases in body mass index (BMI) and waist circumferences were observed while small non-significant improvements in other cardiovascular risk factors were seen. Patients with high baseline BMI and patients with duration of treated illness beyond 2 years had significantly better intervention outcomes. CONCLUSION Our results show that it was difficult to improve physical health in a group of non-selected patients with schizophrenia as part of routine care. The patients were not easily motivated to participate in the interventions, and it was difficult to monitor the recommended metabolic risk measures in the patient group. Future research should focus on simple strategies in health promotion that can be integrated into routine care.

Abstract
PURPOSE To compare the rates of antipsychotic response, remission, and relapse in patients with schizophrenia treated with olanzapine or other antipsychotics in usual clinical care in Japan. PATIENTS AND METHODS This analysis of a 12-month, prospective, noninterventional study examined outcomes for 1,089 inpatients and outpatients with schizophrenia who initiated antipsychotic monotherapy. All treatment decisions, including medication choice, were left to the discretion of the treating physician. The rates of treatment response, relapse, and 6-month sustained remission were compared between olanzapine monotherapy (OLZ) and other anti-psychotic monotherapy (OAN), and between OLZ and other atypical antipsychotic monotherapy (OAT). Visit-wise comparisons of treatment response and remission were examined using repeated-measures logistic regressions. Propensity scores were used to control for potential baseline differences between groups. RESULTS Response rates were higher for OLZ patients and relapse rates were consistently lower for OLZ patients, however the differences were not statistically significant. Rates of 6-month sustained remission were significantly higher for OLZ than OAN patients (P=0.032) and for OLZ than OAT patients (P=0.041). An exploratory analysis of OLZ and OAN comparison found outpatients treated with OLZ or OAN had similar sustained remission rates (OLZ: 22.2%, OAN: 22.8%), while inpatients treated with OLZ had significantly higher sustained remission rates than inpatients treated with OAN (OLZ: 17.1%, OAN: 6.6%, odds ratio [95% confidence interval] =3.54 [2.00-6.25]). CONCLUSION In usual care in Japan, treating the acute symptoms of schizophrenia with olanzapine was not found to be significantly different for response and relapse rates; however, treatment with olanzapine was found to have significantly greater sustained remission rates than treatment with other antipsychotics. In the inpatient setting, where patients tend to be more severe and difficult to manage, olanzapine treatment may lead to higher sustained remission rates than other antipsychotics.

Abstract
OBJECTIVE This study aims to assess the proportion of patients with schizophrenia or bipolar disorder who discontinued treatment with one of two oral formulations of olanzapine within 12 months in outpatient settings in Germany, Greece, and France. METHODS This 1-year, prospective, observational study included patients who had recently initiated treatment with olanzapine-coated tablets (OC) or the orodispersible (OD) formulation. Primary endpoint was olanzapine discontinuation for any reason. Clinical and functional status were also evaluated. RESULTS Out of 927 enrolled patients, 903 were included in the analyses (612 patients with schizophrenia, 291 with bipolar disorder). Within 12 months, 46 of 903 patients discontinued olanzapine. Most (95%) patients remained on olanzapine for 12 months with similar rates for patients with either diagnosis (94.5% for schizophrenia, 94.9% for bipolar disorder) and for both formulations (93.7% with OC, 95.3% with OD). The only factor significantly associated with time to discontinuation was baseline disease severity. Patients with more severe disease at baseline had a lower discontinuation risk. There were significant improvements in functioning and well-being and non-significant improvements in therapeutic alliance and compliance. CONCLUSIONS No significant difference was seen between discontinuation rates of the two formulations. Higher baseline severity was associated with a lower discontinuation rate.

Abstract
Knowledge regarding socio-demographic and clinical risk factors of medication nonadherence does not always help in addressing adherence in individual patients. Classifying patients according to subjective adherence influencing factors may aid practitioners in choosing adequate strategies for improving medication adherence. A total of 171 outpatients with schizophrenia and schizoaffective disorder were classified according to factors influencing their medication adherence assessed using the Rating of Medication Influences Scale. Additionally, psychotic symptoms, depression, and insight, also known to influence pharmacological treatment motivation, were assessed. A cluster analysis yielded 3 groups that were distinguished both by the relative ranking of adherence influences and by specific associations with risk factors of nonadherence. For the "Interpersonal, Future-oriented Group" (n=59, 35% of the sample), interpersonal factors (positive therapeutic relationship, positive attitudes of significant others towards medication), immediate positive consequences of the medication intake (daily benefits, no perceived pressure to take medication), and avoiding future negative consequences of non-compliance, such as relapse and re-hospitalization, were essential for adherence. The "Autonomous, Future-oriented Group" (n=69, 40% of the sample) appraised interpersonal factors as being less important as compared to the other groups. This group exhibited significantly fewer depressive symptoms than the first group and had significantly more stable partnerships as compared to the other groups. The "Autonomous, Present-oriented Group" (n=43, 25% of the sample) was mainly motivated by immediate positive consequences and displayed higher levels of cognitive disorganization and negative symptoms than the second group, as well as the lowest level of insight of all groups. Treatment strategies addressing adherence enhancement in schizophrenia may profit by considering both the patient's subjective adherence attitude profile as well as the specific pattern of risk factors for nonadherence including depression, lack of insight, negative syndrome, cognitive disorganization and socio-demographic factors, which are differentially associated with each adherence attitude profile.

Abstract
To assess baseline predictors and consequences of antipsychotic adherence during the long-term treatment of schizophrenia outpatients, data were taken from the 3-year, prospective, observational, European Schizophrenia Outpatients Health Outcomes (SOHO) study, in which outpatients starting or changing antipsychotics were assessed every 6 months. Physician-rated adherence was dichotomized as adherence/non-adherence. Regression models tested for predictors of adherence during follow-up, and associations between adherence and outcome measures. Of the 6731 patients analysed, 71.2% were adherent and 28.8% were non-adherent over 3 years. The strongest predictor of adherence was adherence in the month before baseline assessment. Other baseline predictors of adherence included initial treatment for schizophrenia and greater social activities. Baseline predictors of non-adherence were alcohol dependence and substance abuse in the previous month, hospitalization in the previous 6 months, independent housing and the presence of hostility. Non-adherence was significantly associated with an increased risk of relapse, hospitalization and suicide attempts. In conclusion, non-adherence is common but can partly be predicted. This may allow strategies to improve adherence to be targeted to high-risk patients. Also, reversal of some risk factors may improve adherence. Non-adherence is associated with a range of poorer long-term outcomes, with clinical and economic implications.

Abstract
BACKGROUND Studies describing long-term continuous care of outpatients with schizophrenia are relatively scarce. The prospective European Schizophrenia Outpatient Health Outcomes study (SOHO) provides data on a cohort of schizophrenic patients over a period of three years. METHODS Prospective, long-term, observational study including outpatients who initiate therapy or change to a new antipsychotic. The study was designed to provide two patient groups of approximately equal size: treated either with olanzapine or a non-olanzapine antipsychotic. Sociodemographic, clinical and disease characteristics at baseline were described. Clinical severity of symptoms was assessed at each visit using the Clinical Global Impression scale (CGI). Treatment outcomes were analyzed as treatment discontinuation, remission and relapse rates. RESULTS French results are presented in this report. Nine hundred and thirty-three patients (62% males) were recruited between March and December 2001. The mean age was 37.1+/-11.5 years. The mean time since first consultation for schizophrenia was 8.0+/-9.3 years. At study baseline, one quarter had paid employment, less than one third had a spouse or partner and more than half of them had an independent housing. Thirty percent of patients reported a previous suicide attempt. The mean CGI was 4.5+/-1.0 at admission. Overall, medication discontinuation for any cause occurred for 42% of patients. A remission (defined by a CGI<or=3 maintained for 6 months, without hospitalization) was obtained in 63% of patients, 49% of patients relapsed (defined as hospitalization or CGI increase reaching 4 or more) during the three-year follow-up period. A suicide attempt occurred in 60 patients (cumulative proportion 7%). CONCLUSIONS The clinical findings of the French cohort of patients confirmed the high burden of the disease. Identification of risk factors for discontinuation of treatment should provide a better individualization of patient care and a better impact on the different domains of effectiveness.
