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

Progress in personalised psychiatry is dependent on researchers having access to systematic and accurately acquired symptom data across clinical diagnoses. We have developed a structured psychiatric assessment tool, OPCRIT+, that is being introduced into the electronic medical records system of the South London and Maudsley NHS Foundation Trust which can help to achieve this. In this report we examine the utility of the symptom data being collected with the tool. Cross-sectional mental state data from a mixed-diagnostic cohort of 876 inpatients was subjected to a principal components analysis (PCA). Six components, explaining 46% of the variance in recorded symptoms, were extracted. The components represented dimensions of mania, depression, positive symptoms, anxiety, negative symptoms and disorganization. As indicated by component scores, different clinical diagnoses demonstrated distinct symptom profiles characterized by wide-ranging levels of severity. When comparing the predictive value of symptoms against diagnosis for a variety of clinical outcome measures (e.g. 'Overactive, aggressive behaviour'), symptoms proved superior in five instances (R(2) range: 0.06-0.28) whereas diagnosis was best just once (R(2):0.25). This report demonstrates that symptom data being routinely gathered in an NHS trust, when documented on the appropriate tool, have considerable potential for onward use in a variety of clinical and research applications via representation as dimensions of psychopathology.
