Abstract
OBJECTIVE We conducted a 12-week double-blind study of stabilization pharmacotherapy in patients with remitted psychotic depression (PD). METHODS Seventy-one persons aged 18 years or older who had achieved remission of PD when randomized to either olanzapine plus sertraline or olanzapine plus placebo were continued on the double-blind treatment associated with remission. Symptoms of depression and psychosis, and weight, were measured once every 4 weeks. Cholesterol, triglycerides, and glucose were measured at stabilization phase baseline and Week 12/termination. RESULTS The effect of treatment did not significantly change with time for depression, weight, or metabolic measures in the stabilization phase. Eight of the 71 participants (11.3%; 95% CI: 5.8, 20.7) experienced a relapse of major depression, psychosis, or both. Treatment groups did not differ in the frequency of relapse. In the entire study group, the adjusted estimate for change in weight was an increase of 1.66 kg (95% CI: 0.83, 2.48) and the adjusted estimate for change in total cholesterol was a decrease of 14.8 mg/dL (95% CI: 3.5, 26.1) during the 12-week stabilization phase; the remaining metabolic measures did not significantly change. CONCLUSION Continuation of acute treatment was associated with stability of remission.

Abstract
Research findings are particularly important for medication choice for first-episode patients as individual prior medication response to guide treatment decisions is unavailable. We describe the first large-scale double-masked randomized comparison with first-episode patients of aripiprazole and risperidone, 2 commonly used first-episode treatment agents. One hundred ninety-eight participants aged 15-40 years with schizophrenia, schizophreniform disorder, schizoaffective disorder or psychotic disorder Not Otherwise Specified, and who had been treated in their lifetime with antipsychotics for 2 weeks or less were randomly assigned to double-masked aripiprazole (5-30 mg/d) or risperidone (1-6 mg/d) and followed for 12 weeks. Positive symptom response rates did not differ (62.8% vs 56.8%) nor did time to response. Aripiprazole-treated participants had better negative symptom outcomes but experienced more akathisia. Body mass index change did not differ between treatments but advantages were found for aripiprazole treatment for total and low-density lipoprotein cholesterol, fasting glucose, and prolactin levels. Post hoc analyses suggested advantages for aripiprazole on depressed mood. Overall, if the potential for akathisia is a concern, low-dose risperidone as used in this trial maybe a preferred choice over aripiprazole. Otherwise, aripiprazole would be the preferred choice over risperidone in most situations based upon metabolic outcome advantages and some symptom advantages within the context of similar positive symptom response between medications.

Abstract
This randomized open-label study compared the incidence of metabolic side effects of aripiprazole, ziprasidone and quetiapine in a population of medication-naïve first-episode psychosis patients. A total of 202 subjects were enrolled. Body weight, body mass index, leptin, fasting lipids and fasting glycaemic parameters were measured at baseline and at 3 months follow-up. A hundred and sixty-six patients completed the follow-up and were included in the analyses. A high proportion of patients experienced a significant weight increase (>7% of their baseline weight): 23% ziprasidone (n=12), 32% with quetiapine (n=16) and 45% with aripiprazole (n=31). Patients treated with aripiprazole gained significantly more weight than the patients in the ziprasidone group (1.2 kg [SD=4.1] versus 4.3 kg [SD=4.8], respectively). The increase in leptin levels was greater in women treated with aripiprazole than in those treated with ziprasidone (p=0.030). Mean prolactin levels significantly increased in patients treated with quetiapine and ziprasidone but not in those treated with aripiprazole. Patients treated with quetiapine and aripiprazole showed a significant increase in total cholesterol and LDL-cholesterol plasma levels. Quetiapine-treated patients resulted in a higher increase in LDL-cholesterol than patients treated with ziprasidone (p=0.021). No other significant differences between groups were found. No significant changes in glycaemic parameters were observed. Our results suggest that ziprasidone has a lower liability for inducing weight gain and lipid abnormalities than aripiprazole or quetiapine.

Abstract
OBJECTIVE To compare longer-term safety and effectiveness of the 4 most commonly used atypical antipsychotics (aripiprazole, olanzapine, quetiapine, and risperidone) in 332 patients, aged > 40 years, having psychosis associated with schizophrenia, mood disorders, posttraumatic stress disorder, or dementia, diagnosed using DSM-IV-TR criteria. METHOD We used equipoise-stratified randomization (a hybrid of complete randomization and clinician's choice methods) that allowed patients or their treating psychiatrists to exclude 1 or 2 of the study atypical antipsychotics due to past experience or anticipated risk. Patients were followed for up to 2 years, with assessments at baseline, 6 weeks, 12 weeks, and every 12 weeks thereafter. Medications were administered employing open-label design and flexible dosages, but with blind raters. The study was conducted from October 2005 to October 2010. OUTCOME MEASURES Primary metabolic markers (body mass index, blood pressure, fasting blood glucose, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and triglycerides), percentage of patients who stay on the randomly assigned atypical antipsychotic for at least 6 months, psychopathology, percentage of patients who develop metabolic syndrome, and percentage of patients who develop serious and nonserious adverse events. RESULTS Because of a high incidence of serious adverse events, quetiapine was discontinued midway through the trial. There were significant differences among patients willing to be randomized to different atypical antipsychotics (P < .01), suggesting that treating clinicians tended to exclude olanzapine and prefer aripiprazole as one of the possible choices in patients with metabolic problems. Yet, the atypical antipsychotic groups did not differ in longitudinal changes in metabolic parameters or on most other outcome measures. Overall results suggested a high discontinuation rate (median duration 26 weeks prior to discontinuation), lack of significant improvement in psychopathology, and high cumulative incidence of metabolic syndrome (36.5% in 1 year) and of serious (23.7%) and nonserious (50.8%) adverse events for all atypical antipsychotics in the study. CONCLUSIONS Employing a study design that closely mimicked clinical practice, we found a lack of effectiveness and a high incidence of side effects with 4 commonly prescribed atypical antipsychotics across diagnostic groups in patients over age 40, with relatively few differences among the drugs. Caution in the use of these drugs is warranted in middle-aged and older patients. TRIAL REGISTRATION ClinicalTrials.gov identifier: NCT00245206.

Abstract
BACKGROUND Schizoaffective disorder shares clinical characteristics with schizophrenia and affective disorders, with patients experiencing concurrent manic, mixed, or depressive episodes during psychosis. Because efficacy may be better in schizoaffective disorder than schizophrenia, this post-hoc analysis examines the efficacy, safety, and tolerability of aripiprazole in patients with schizoaffective disorder. METHOD Data were obtained from a sub-sample of subjects with schizoaffective disorder (randomized: aripiprazole n=123, placebo n=56) who participated in two 4-week, multicenter, double-blind trials of subjects with schizophrenia or schizoaffective disorder. Aripiprazole was administered at fixed doses of 15 mg/day, 20 mg/day, or 30 mg/day. Efficacy assessments included the Positive and Negative Syndrome Scale (PANSS) Total score, and the Positive, Negative, and General Psychopathology subscale scores. Safety and tolerability evaluations included incidence of treatment-emergent adverse events and extrapyramidal symptom assessments (SAS, BARS, and AIMS), and metabolic profile changes including weight and BMI. RESULTS A significantly greater improvement from baseline to endpoint was observed with aripiprazole compared with placebo on the PANSS Total (-15.9 vs. -3.4; p=0.038) and PANSS Positive subscale (-4.6 vs. -1.0; p=0.027). Differences between treatments were not significant for the PANSS Negative subscale score (-3.7 vs. -1.2; p=0.15) or PANSS General Psychopathology subscale score (-8.3 vs. -3.1; p=0.06). There were no statistically significant differences at endpoint between groups in the mean change from baseline to endpoint in weight, glucose, or total cholesterol, or on SAS, BARS, or AIMS scores. There was a statistically significant decrease in prolactin in subjects treated with aripiprazole compared with placebo (-5.6 vs. -1.3, p<0.001). CONCLUSION Aripiprazole was efficacious and well tolerated in patients with schizoaffective disorder.

Abstract
Few studies have assessed the comparative efficacy and safety of atypical and typical antipsychotic medications in patients within their first episode of psychosis. This study examined the effectiveness of the atypical antipsychotic olanzapine and the typical antipsychotic haloperidol in patients experiencing their first episode of a schizophrenia-related psychotic disorder over a 2-year treatment period. Two hundred and sixty-three patients were randomized to olanzapine or haloperidol in a doubleblind, multisite, international 2-year study. Clinical symptoms and side effects were assessed at baseline and longitudinally following randomization for the duration of the study. Olanzapine and haloperidol treatment were both associated with substantial and comparable reductions in symptom severity (the primary outcome measure) over the course of the study. However, the treatment groups differed on two secondary efficacy measures. Patients were less likely to discontinue treatment with olanzapine than with haloperidol: mean time (in days) in the study was significantly greater for those treated with olanzapine compared to haloperidol (322.09 vs. 230.38, p<0.0085). Moreover, remission rates were greater in patients treated with olanzapine as compared to those treated with haloperidol (57.25% vs. 43.94%, p<0.036). While extrapyramidal side effects were greater in those treated with haloperidol, weight gain, cholesterol level and liver function values were greater in patients treated with olanzapine. The data from this study suggest some clinical benefits for olanzapine as compared to haloperidol in first episode patients, which must be weighed against those adverse effects that are more likely with olanzapine.

The Journal of clinical psychiatry. 2006;(4):547-53
Abstract
BACKGROUND The main objective was to assess the efficacy of a weight management program designed for outpatients taking olanzapine for schizophrenia or schizoaffective disorder and to compare these patients with a randomized control group. The effects of the weight management program were also assessed with regard to safety and quality of life. METHOD Forty-eight patients were enrolled in a 12-week, randomized, multicenter weight management study. Thirty-three patients were randomly allocated to an intervention group in which they received olanzapine within a weight management program. Fifteen patients were allocated to a control group in which they were given olanzapine treatment as usual outpatients. Weight, body mass index (BMI), and measurements of safety and quality of life were evaluated. The study was conducted from January 7, 2003, to September 16, 2003. RESULTS Thirty-six patients (75%) completed this study. We found significant differences in weight (-3.94 +/- 3.63 kg vs. -1.48 +/- 1.88 kg, p = .006) and BMI (-1.50 +/- 1.34 vs. -0.59 +/- 0.73, p = .007) change from baseline to endpoint between the intervention and control groups, respectively. Significant differences in weight reduction were initially observed at week 8 (p = .040). No significant differences were found with regard to the safety outcomes. When the ratio of low-density lipoproteins to high-density lipoproteins was calculated, change from baseline was greater in the intervention group than the control group (-0.19 vs. -0.04), but the difference was not statistically significant (p = .556). After the completion of the weight management program, there was a trend toward statistical difference in the physical health score changes between the weight management and control groups (1.12 in the intervention group vs. -0.93 in the control group, p = .067). CONCLUSION The weight management program was effective in terms of weight reduction in patients with schizophrenia or schizoaffective disorder taking olanzapine and was also found to be safe in terms of psychiatric symptoms, vital signs, and laboratory data. In addition, such a weight management program might improve quality of life in patients with schizophrenia or schizoaffective disorder with respect to their physical well-being.

Harefuah. 2003;(8-9):592-6, 647
Abstract
INTRODUCTION Although there is great progress in the treatment of positive symptoms in schizophrenic patients and movement disorders induced by neuroleptics, it is still a problem for clinicians. In this study vitamin B6 treatment was provided to 15 patients who suffered from schizophrenia and schizoaffective disorder with positive psychotic symptoms and tardive dyskinesia. METHODS This study was a double-blind crossover controlled during 9 weeks. Each patient was treated with up to 400 mg/day vitamin B6 versus placebo. Every week the patients' conditions were evaluated with Positive and Negative Symptoms Scale (PANSS), Extrapyramidal Symptoms Rating Scale (ESRS) and a blood sample of level pyridoxal was taken. RESULTS The results did not show any therapeutic effect of psychotic symptoms from vitamin B6 added to antipsychotic agents, which patients received on a constant base. On the other hand, there was significant improvement in tardive dyskinesia and parkinsonian symptoms. There was no direct correlation between pathological symptoms and the serum baseline level of vitamin B6 nor its level during the treatment. CONCLUSION The authors suggest that vitamin B6 may be efficient as the treatment for tardive dyskinesia and parkinsonism induced by neuroleptic agents. There is a need for further studies with larger samples and higher doses of vitamin B6 in order to examine the possibility of a positive therapeutic effect as an augmentation agent for the treatment of psychotic symptoms.

Smoking, gender, and dietary influences on erythrocyte essential fatty acid composition among patients with schizophrenia or schizoaffective disorder.
Hibbeln, JR, Makino, KK, Martin, CE, Dickerson, F, Boronow, J, Fenton, WS
Biological psychiatry. 2003;(5):431-41
Abstract
BACKGROUND Prior reports of decreased levels of essential fatty acids among schizophrenic patients have generated several hypotheses proposing inherent abnormalities in phospholipid and fatty acid metabolism and have provided the basis for treatment trials; however, these essential fatty acid aberrations may be attributable to uncontrolled factors, such as smoking, rather than abnormalities inherent to schizophrenia. METHODS Erythrocyte fatty acid compositions were quantified in 72 medicated schizophrenic or schizoaffective patients both at baseline and after 16 weeks of supplementation with 3 g/day of either ethyl-eicosapentaenoic acid or placebo. Current smoking status, gender, dietary survey, and Montgomery Asburg Depression Rating Scale, Repeatable Battery for the Assessment of Neuropsychological Status, Abnormal Involuntary Movement Scale, and Positive and Negative Syndrome Scale scores were assessed. RESULTS Schizophrenic patients who smoked had lower baseline erythrocyte docosahexaenoic acid percent (2.98 +/-.7 vs. 3.59 +/- 1.2, p <.005) and eicosapentaenoic acid (EPA) percent (.39 +/-.13 vs. 47 +/-.22, p <.05), compared with nonsmokers, with a significant gender interaction (p <.01) in multivariate analyses of variance. Baseline arachidonic acid did not differ. Smokers reported lower dietary intake (percent total fat) of linolenic acid (F = 10.1, p <.003) compared with nonsmokers. Nonsmoking women reported greater dietary intake of EPA compared with smoking men or nonsmokers of either gender. CONCLUSIONS Smoking status, gender, and dietary intake significantly predicted erythrocyte polyunsaturated fatty acid status among schizophrenic patients. No evidence was found for subgroups of schizophrenia or relationships to specific symptom severity on the basis of erythrocyte fatty acids. Prior reports of abnormalities of essential fatty acid metabolism among schizophrenic patients may have been an artifact of patients' smoking behavior and differences in dietary intake of omega-3 fatty acids.
