RESUMO

OBJECTIVE: Akathisia is among the most unpleasant side effects related to antipsychotic drug (AP) use, and possible associations between akathisia and agitation, depression and suicidal behaviour, respectively, have been described in previous literature. New generation antipsychotics are however regarded less prone to induce this particular adverse effect compared to older drugs, but evidence is incomplete and in need of confirmation from clinically relevant samples and settings. We, therefore, aim to investigate akathisia at hospital discharge for patients consecutively admitted with acute-phase psychosis and treated with atypical antipsychotics according to guideline-concordant clinical practice. METHODS: This exploratory study is part of a naturalistic randomised controlled study in patients admitted with acute phase psychosis (N = 109). We report cross-sectional data at discharge/first follow-up after acute psychiatric hospital admission for patients with schizophrenia and related psychotic disorders. RESULTS: There were statistically significant positive associations between akathisia and the following; suicidality in men (Beta 0.306, p = 0.048), but not in women; agitation in those previously unexposed to antipsychotics (Beta 0.288, p = 0.047) and depression in those exposed to antipsychotics before hospital admittance (Beta 0.375, p = 0.031). CONCLUSION: Main findings were that akathisia is still a prevalent side effect in a clinically relevant sample of patients treated with atypical antipsychotics. Our results suggest that akathisia is significantly associated with depression, suicidality and agitation in different subgroups of patients receiving APs. Akathisia can be detrimental and the relations between akathisia and depression, suicidality and agitation should be investigated further in prospective, hypothesis-testing studies with larger samples.

RESUMO

BACKGROUND: Amisulpride, aripiprazole, and olanzapine are first-line atypical antipsychotics that have not previously been compared head-to-head in a pragmatic trial. We aimed to compare the efficacy and safety of these agents in a controlled trial. METHODS: This pragmatic, rater-blind, randomised controlled trial was done in three academic centres of psychiatry in Norway, and one in Austria. Eligible patients were aged 18 years or older, met ICD-10 criteria for schizophrenia-spectrum disorders (F20-29), and had symptoms of active psychosis. Eligible patients were randomly assigned to receive oral amisulpride, aripiprazole, or olanzapine. Treatment allocation was open to patients and staff, and starting dose, treatment changes, and adjustments were left to the discretion of the treating physician. Computer-generated randomisation lists for each study centre were prepared by independent statisticians. Patients were followed up for 52 weeks after random assignment, during which assessments were done 8 times by researchers masked to treatment. The primary outcome was reduction of the Positive And Negative Syndrome Scale (PANSS) total score at 52 weeks, and primary analyses were done in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NCT01446328. FINDINGS: Between Oct 20, 2011, and Dec 30, 2016, we assessed 359 patients for eligibility. 215 patients were excluded (107 did not meet inclusion criteria, 82 declined to participate, 26 other reasons). 144 patients (mean baseline PANSS total estimated score 78·4 [SD 1·4]) were randomly assigned 1:1:1 to receive amisulpride (44 patients), aripiprazole (48 patients) or olanzapine (52 patients). After 52 weeks, the patients allocated to amisulpride had a PANSS total score reduction of 32·7 points (SD 3·1) compared with 21·9 points reduction with aripiprazole (SD 3·9, p=0·027) and 23·3 points with olanzapine (2·9, p=0·025). We observed weight gain and increases of serum lipids and prolactin in all groups. 26 serious adverse events (SAEs) among 20 patients were registered (four [9%] of 44 patients allocated to amisulpride, ten [21%] of 48 patients allocated to aripiprazole, and six [12%] of 52 patients allocated to olanzapine), with no statistically significant differences between the study drugs. 17 (65%) of the 26 SAEs occurred during the use of the study drug, with readmission or protracted hospital admission accounting for 13 SAEs. One death by suicide, one unspecified death, and one life-threatening accident occurred during follow-up, after cessation of treatment. INTERPRETATION: Amisulpride was more efficacious than aripiprazole or olanzapine for reducing the PANSS total scores in adults with schizophrenia-spectrum disorders. Side-effect differences among the groups were generally small. This study supports the notion that clinically relevant efficacy differences exist between antipsychotic drugs. Future research should aim to compare first-line antipsychotics directly in pragmatic clinical trials that reflect everyday clinical practice. FUNDING: The Research Council of Norway, the Western Norway Regional Health Trust, and participating hospitals and universities.

RESUMO

Introduction: Psychosis is a multifaceted clinical phenomenon in which the various symptoms may show a differential response to treatment. Important information may be lost when heterogeneous symptoms are grouped together in global sum scores when studying treatment effects.Aims: The aim of this study was to compare the level and rate of change in the two separate symptoms hallucinations and delusions during the acute psychotic phase, and to explore whether potential temporal differences depend on diagnosis or patients being previously medicated with antipsychotics or not.Method: Patients admitted with active symptoms of schizophrenia or related psychotic disorders were included in the Bergen Psychosis Project (BPP) (N = 226), a prospective, pragmatic, study of four second-generation antipsychotics. The Positive and Negative Syndrome Scale were assessed at baseline, one, three and six months.Results: Over the total follow-up period, latent growth curve models showed greater reductions in delusions than in hallucinations. However, the percentage of the total reduction was found to be larger in hallucinations than that of delusions in the first interval (91% vs. 64%). The levels and changes in these variables were dependent on diagnosis and whether or not patients had a life-time history of antipsychotic use.Conclusion: Focusing on separate symptoms rather than general symptom clusters could offer clinicians a useful approach when evaluating the early response of antipsychotics.ClinicalTrials.gov ID: NCT00932529; URL: http://www.clinicaltrials.gov/.
