The switch to LAI-AMT may help to address the subjective core of an optimal recovery in stabilized schizophrenic patients. A sustained improvement in patients' attitude towards drug may help to achieve patient's compliance. The size of this study needs to be expanded to produce more solid and generalizable results.

Our study indicates possible advantages of LAI over oral antipsychotic formulation in terms of subjective experience of maintenance treatment in remitted schizophrenic patients. Size and duration of this study need to be expanded in order to produce more solid and generalizable results.

Objective: Switching to long-acting injectable (LAI) antipsychotic maintenance treatment (AMT) represents a valuable strategy for schizophrenia. In a recovery-oriented approach, patient-reported outcomes (PROs) such as perceived disability, subjective well-being, and quality of life cannot be neglected. Methods: Forty clinically stable outpatients with schizophrenia treated with oral second-generation antipsychotics were enrolled at the time of switching to the equivalent dose of LAI. 35 subjects completed this 2-year longitudinal, prospective, open-label, observational study. Patients were assessed at baseline, after 1 year, and after 2 years of LAI-AMT, using psychometric scales (Positive And Negative Syndrome Scale, PANSS; Young Mania Rating Scale, YMRS; Montgomery-Åsberg Depression Rating Scale, MADRS), PROs (Subjective Well-Being under Neuroleptics short form, SWN-K; Short Form-36 health survey, SF-36; 12-item World Health Organisation Disability Assessment Schedule, WHODAS 2.0), and caregiver-reported outcomes (12-item WHODAS 2.0). Results: No psychotic relapses were observed. Psychopathology measures (PANSS total and subscalesexcluding negative symptoms), mood symptoms (YMRS, MADRS), perceived disability (patient-and caregiver-administered WHODAS 2.0), subjective well-being (SWN-K), and quality of life (SF-36) showed a concomitant amelioration after 1 year, without further significant variations. Discussion: Switching to LAI-AMT may decrease perceived impairment, and increase subjective wellbeing and quality of life in clinically stable outpatients with schizophrenia. HIGHLIGHTSLAI treatment may improve outcomes by reducing psychopathology levels and relapses. In a recovery-oriented approach, patient-reported outcomes cannot be neglected. LAI antipsychotics may optimise the subjective experience of treatment. Switching to LAI therapy may result in a reduction in perceived disability. There is a significant correlation between proxy-and patient-reported disability.

Cariprazine is a third-generation antipsychotic medication approved for the treatment of schizophrenia and bipolar disorder, with unique pharmacodynamic and pharmacokinetic properties. In this case series, the functional and symptomatic improvement of three patients who had been diagnosed with different psychiatric disorders and who exhibited various symptoms from psychotic to mood symptoms is described. The first case is about a young male patient with bipolar disorder and cocaine abuse who managed to become abstinent from cariprazine. The second and third cases describe patients with psychosis suffering from positive, cognitive and mood symptoms who were non-adherent to previous medication. In both cases, cariprazine was well-tolerated and effective in alleviating symptoms, thus improving their everyday functioning as well. In the discussion, the associations between symptom domains and the receptor profile of cariprazine are also highlighted, providing an explanation of the observed effects. It is concluded that cariprazine is a good treatment option for patients with symptoms of psychosis and addiction; is well-tolerated without the induction of side effects such as weight gain or sedation; and is appropriate for patients who have problems with adherence.

Given the importance of patients' subjective experience and attitudes in the management of severe mental illness, the present study evaluated their potential role as predictors of future continuation of long-acting injectable antipsychotic maintenance treatment (LAI-AMT) in clinically stable outpatients with schizophrenia switching from an oral therapy. Retrospective data from 59 subjects receiving LAI-AMT for at least 6 months were collected. Patients who continued LAI treatment (n = 32) were compared to those who discontinued it (n = 27), assessing baseline socio-demographic and clinical characteristics, psychopathological features (Positive And Negative Syndrome Scale, Montgomery-Åsberg Depression Rating Scale and Young Mania Rating Scale) and patient-reported experience of treatment through Drug Attitude Inventory 10-item (DAI-10) and Subjective Well-being under Neuroleptics short form. Binary logistic and Cox regression analyses explored the predictive role of the mentioned variables on treatment discontinuation. The Kaplan-Meier estimator compared dropout from LAI treatment in subsamples with different characteristics.Unemployment and lower baseline DAI-10 scores predicted LAI-AMT discontinuation. No major differences were detected in other socio-demographic, clinical or psychometric indexes. When switching from oral to LAI-AMT, the preliminary assessment of attitude towards drug might be clinically relevant, allowing the identification of patients at risk for treatment discontinuation.

IntroductionLimited research has been devoted to the subjective impact of switching antipsychotic maintenance treatment (AMT) from oral to LAI formulation in schizophrenia.ObjectiveTo compare LAI AMT with oral AMT in terms of subjective experience of treatment, taking into account the effects on psychopathology.MethodsTwenty outpatients (7 males, mean age 40.55 ± 11.00 years) with remitted schizophrenia treated with either olanzapine or paliperidone and switching from oral to LAI AMT were recruited before the switch (LAI-AMT group). A group of 20 remitted schizophrenic subjects with oral AMT and matched for the main socio-demographic, clinical and treatment variables made up the controls (oral-AMT group). All participants were assessed by means of the PANSS and of the SWN-K at baseline (T0) and after 6 months (T1).ResultsBetween T0 and T1, general psychopathology of the PANSS and all but one of the SWN-K dimensions (except for “social integration”), showed significantly higher percent improvements in the LAI-AMT group compared to the oral-AMT group. After 6 months (T1), the LAI-AMT group showed significantly lower PANSS total and general psychopathology scores, as well as higher mean score of perceived “mental functioning” compared to the oral-AMT group. Item analysis of the general PANSS at T1 showed significant differences between the two groups in anxiety, tension, depression, guilt feelings, poor attention, and active social avoidance.ConclusionsOur data on switching from oral to LAI AMT in remitted schizophrenia suggest a better efficacy of the latter in terms of improvement of general psychopathology and subjective experience of treatment.Disclosure of interestThe authors have not supplied their declaration of competing interest.
