© 2017 Elsevier Ltd While positron emission tomography (PET) studies have provided invaluable data on antipsychotic effects, selection bias remains a serious concern. A systematic review of PET studies that measured dopamine D2 receptor blockade with antipsychotics was conducted to examine their inclusion/exclusion criteria, using PubMed, EMBASE, and ClinicalTrials.gov (last search, September 2016). PET studies were included if they measured D2 receptor occupancy in patients with schizophrenia and included introduction of antipsychotic treatment or antipsychotic regimen change in a systematic manner. Twenty-six studies were identified. Age limit was included in 13 studies; one study solely included geriatric patients while others targeted younger adults. Eleven, 6, and 3 studies specifically targeted clinically stable patients, patients with severe psychopathology, and antipsychotic-free patients, respectively. Nineteen and 18 studies excluded patients with physical comorbidity and substance abuse, respectively. As a result, the mean age of subjects ranged from 23 to 42 years when one study that targeted geriatric patients was excluded. Mean Positive and Negative Syndrome Scale total scores ranged from 54 to 95. No comparison active-drug or placebo arm was employed in 24 studies. Blind assessment of symptomatology was performed in 5 studies. In general, subjects participating in clinical PET studies were relatively young, presented with mild symptomatology, and were free from substance abuse or physical comorbidities. These characteristics need to be taken into account when clinical PET data are interpreted. On the other hand, it should also be noted that this study was only qualitative and conservative interpretation is necessary for possibility of subjective bias.

Objective: The aim of this post hoc analysis was to evaluate which specific depressive items could predict subsequent durable recovery in patients with bipolar depression. Methods: The study population was at least 18 years old and met DSM-IV criteria for a major depressive episode associated with either bipolar I or II disorder. The data were derived from the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD), in which patients with bipolar depression were randomly assigned to treatment for acute depression with a mood stabilizer plus an adjunctive antidepressant drug or placebo. The primary and secondary outcomes were durable recovery (ie, 8 consecutive weeks of euthymia) and treatment-emergent affective switch (ie, transition to mania or hypomania), respectively. Binary logistic regression analysis was performed to identify specific symptoms whose improvement during the first 2 weeks predicted those outcomes; the score change of each individual symptom in the continuous symptom subscales for depression (SUM-D) from week 0 to week 2 was used as an independent variable. Results: In the evaluable 188 participants who took placebo and active drugs, the improvement in loss of self-esteem (P =.037) or loss of energy (P =.040) at week 2 was significantly associated with higher chances of subsequent durable recovery. For participants taking active drugs (n = 91), solely the improvement in loss of energy at week 2 was significantly associated with subsequent durable recovery (P =.027). There was a significant association between the improvement of psychomotor retardation at week 2 and subsequent affective switch (P =.008). Conclusions: These findings imply that focusing on individual symptoms is important in bipolar depression, rather than relying solely on a summed score in rating scales. Trial Registration: The original STEP-BD dataset is registered on ClinicalTrials.gov (identifier: NCT00012558).

Objectives To assess the impact of reducing the dose of antipsychotics on cognition and dopaminergic D₂ receptor availability in the whole striatum, and identify their relationship in patients with schizophrenia aged 50 years or older. Design Open-label prospective PET [¹¹C]-raclopride study. Setting A tertiary care center outpatient setting. Participants Thirty-seven clinically stable participants with schizophrenia or schizoaffective disorder, aged 50 years or greater, and having been treated with olanzapine or risperidone monotherapy at the same dose for at least 6 months. Intervention Gradual reduction in their olanzapine or risperidone daily dose of up to 40%. Measurements Clinical and cognitive assessments, and [¹¹C]-raclopride PET to determine D₂ receptor availability at baseline and after the dose reduction. Main outcome measures were overall cognition and D₂ receptor availability in whole striatum. Results Reducing the antipsychotic dose resulted in an increase in D₂ receptor availability in the whole striatum and an association between D₂ receptor availability and overall cognition despite lack of change in the latter. There was also an association between change in D₂ receptor availability and change in overall cognition. Conclusions Our findings suggest that optimizing D₂ receptor availability by reducing antipsychotic dose allows this system to contribute more significantly to cognitive function in patients with schizophrenia. This uncovered association could be harnessed by cognitive-enhancing interventions.

Objective: The impact of religious/spiritual activities on clinical outcomes in patients with serious mental illnesses remains controversial, which was addressed in this international cross-sectional study. Method: Three-hundred sixty-nine subjects were recruited from Austria (n = 189) and Japan (n = 180), consisting of 112 outpatients with paranoid schizophrenia, 120 with bipolar I disorder (DSM-IV), and 137 healthy controls. Religiosity was assessed in terms of attendance and importance of religious/spiritual activities, while resilience was assessed using the 25-item Resilience Scale. General linear models were used to test whether higher religiosity will be associated with higher resilience, higher social functioning, and lower psychopathology. The association between levels of spiritual well-being and resilience was also examined. Results: Attendance of religious services (F_[4,365] = 0.827, P = 0.509) and importance of religion/spirituality (F_[3,365] = 1.513, P = 0.211) did not show significant associations with resilience. Regarding clinical measures, a modest association between higher importance of religion/spirituality and residual manic symptoms was observed in bipolar patients (F_[3,118] = 3.120, P = 0.029). In contrast to the findings regarding religiosity, spiritual well-being showed a strong positive correlation with resilience (r = 0.584, P < 0.001). Conclusion: The protective effect of religiosity in terms of resilience, social functioning, and psychopathology was not evident in our sample. Spiritual well-being appears more relevant to resilience than religiosity.

© 2016 Wolters Kluwer Health, Inc. No study has investigated psychological dependence on antidepressants in patients with panic disorder, which was addressed in this study. This study was carried out in four psychiatric clinics in Tokyo, Japan. Individuals were eligible if they were outpatients aged 18 years or older and fulfilled the diagnostic criteria for panic disorder (ICD-10). Assessments included the Japanese Versions of the Severity of Dependence Scale (SDS), the Self-Report Version of Panic Disorder Severity Scale (PDSS-SR), and the Quick Inventory of Depressive Symptomatology-Self Report. Eighty-four individuals were included; of these, 30 patients (35.7%) showed psychological dependence on antidepressants (i.e. a total score of ≥5 in the SDS). A multiple regression analysis showed that PDSS scores and illness duration were correlated positively with SDS total scores. A binary regression model showed that absence of remission (i.e. a total score of ≥5 in the PDSS) and longer duration of illness increased the risk of dependence on antidepressants. Approximately one-third of the patients with panic disorder, receiving antidepressants, fulfilled the criteria for psychological dependence on these drugs. The results underscore the need for close monitoring, especially for those who present severe symptomatology or have a chronic course of the illness.

Introduction Data on the knowledge about antipsychotic medications prescribed in patients with schizophrenia are very limited. Moreover, it remains unclear how patients’ knowledge about prescribed antipsychotics affects medication adherence. Methods ighty-one Japanese outpatients with schizophrenia according to the International Classification of Diseases, 10th edition, were included. Patients’ knowledge of the primary antipsychotics prescribed to them in terms of therapeutic effects, type, and implicated neurotransmitters was assessed with a multiple-choice questionnaire developed for this study. Medication possession ratios (MPRs) were compared between patients who answered correctly and those who did not in each category. Results The percentages of subjects who answered correctly regarding antipsychotic effects, type, and implicated neurotransmitters were low at 30.9%, 30.9%, and 7.4%, respectively. No differences were found in MPRs between subjects who answered correctly and those who did not. Discussion Our preliminary results indicate that patients lack knowledge about their antipsychotic medications. More concerning, they suggest that knowledge about prescribed antipsychotics may not directly translate into actual medication adherence in patients with schizophrenia.

Objective: Although hyperprolactinemia carries a long-Term risk of morbidity, the threshold of dopamine D2/3 receptor (D2/3R) occupancy for hyperprolactinemia has not been investigated in older patients with schizophrenia. Data were taken from a positron emission tomography (PET) study conducted between August 2007 and August 2015. The present post hoc study included 42 clinically stable outpatients with schizophrenia (DSM-IV) (mean SD age = 60.2 6.7 years) taking olanzapine or risperidone. Subjects underwent [11C]-raclopride PET scans to measure D2/3R occupancy before and after reducing their dose of antipsychotic by up to 40%. Blood samples were collected before each PET scan to measure prolactin levels. Methods: The relationship between prolactin levels and D_2/3R occupancy was examined using stepwise linear regression analyses. The D2/3R occupancy thresholds for hyperprolactinemia were explored using Fisher exact tests. Results: Prolactin levels decreased following dose reduction (mean SD = 24.1 30.2 ng/mL to 17.2 15.1 ng/mL; P < .001). Prolactin levels were associated with female gender (β = .32, P = .006, vs male), antipsychotics (β = .23, P = .02, risperidone vs olanzapine), and D_2/3R occupancy (β = .23, P = .04). Those with D_2/3R occupancy of 66% or higher were more likely to have hyperprolactinemia than those with D_2/3R occupancy lower than 66% (P = .03). Sensitivity, specificity, positive predictive value, and negative predictive value of this threshold were 0.44, 0.81, 0.78, and 0.48, respectively. We identified a D_2/3R occupancy threshold for hyperprolactinemia of 66% in older patients with schizophrenia, which is lower than that reported in younger patients (73%) by other researchers. Conclusions: Our results suggest a higher sensitivity to antipsychotics in older patients. Prolactin levels could assist in the determination of appropriate antipsychotic dosing to minimize adverse effects.

© 2016, Springer-Verlag Berlin Heidelberg. Introduction: Dopamine D2 receptor occupancy levels needed for the maintenance treatment of schizophrenia remain to be elucidated. We examined 3-year clinical outcomes of patients with schizophrenia who received long-acting injectable risperidone (LAI risperidone) at baseline and investigated their dopamine D2 receptor occupancy levels, estimated from plasma drug concentrations. Methods: A chart review of 52 outpatients with schizophrenia who participated in the original cross-sectional study was conducted to examine their 3-year clinical outcomes between April and September 2015. Patients who continued outpatient treatment with LAI risperidone without any usage of concomitant chlorpromazine equivalent antipsychotic dosage at >200 mg/day for the 3-year period were asked to participate in the follow-up assessments that included the Brief Psychiatric Rating Scale (BPRS) and estimated dopamine D2 receptor occupancy levels at trough, using plasma concentrations of risperidone plus 9-hydroxyrisperidone. Data were compared with the same patients collected 3 years earlier. Results: Among the original 52 participants, 14 participants (27 %) continued outpatient treatment with LAI risperidone. Ten participants (19 %) provided plasma samples; mean ± SD measured trough concentration of risperidone plus 9-hydroxyrisperidone significantly increased from 22.9 ± 15.6 to 31.8 ± 17.5 ng/mL (P = 0.02). Estimated dopamine D2 receptor occupancy numerically increased from 63.0 ± 10.9 to 69.0 ± 11.0 % (P = 0.12). A significant worsening was observed in the BPRS total score among these patients (mean ± SD, 34.3 ± 12.7 to 46.5 ± 16.9, P = 0.003). Conclusion: Paradoxically, the increased plasma concentration was found to be associated with a significant worsening of the clinical outcome. More investigations are indicated to shed further light on optimal levels of D2 blockade in the maintenance treatment of schizophrenia.

© 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd Objective: Improving quality of life (QoL) is an important objective in the treatment of schizophrenia. The aim of the current study was to examine to what extent resilience, self-esteem, hopelessness, and psychopathology are correlated with QoL. Method: We recruited 52 out-patients diagnosed with schizophrenia according to DSM-IV criteria and 77 healthy control subjects from the general community. In patients, psychopathology was quantified by the Positive and Negative Syndrome Scale. The following scales were used in both patients and control subjects: the Berliner Lebensqualitätsprofil, the Resilience Scale, the Rosenberg Self-Esteem Scale, and the Beck Hopelessness Scale to assess QoL, resilience, self-esteem, and hopelessness respectively. Results: Patients with schizophrenia presented with significantly less QoL, resilience, self-esteem, and hope compared to healthy control subjects. In patients, QoL correlated moderately with resilience, self-esteem, and hopelessness and weakly with symptoms. With respect to the latter, particularly depression and positive symptoms were negatively correlated with QoL. Conclusion: Our results highlight the complex nature of QoL in patients suffering from schizophrenia. They underscore that significant efforts are necessary to enhance resilience and self-esteem and to diminish hopelessness as well as affective and positive symptoms in patients with schizophrenia.
