Abstract Background Current evidence on antipsychotic treatment and risk of psychiatric hospitalization in first-episode schizophrenia (FES) is largely based on the findings from randomized clinical trials (RCTs). However, the generalization of the findings to real-world patients is limited due to inherent caveats of the RCT. We aimed to investigate the treatment discontinuation and risk of psychiatric hospitalization using a nationwide population database. Methods The Health Insurance Review Agency database in South Korea was obtained, and the observation period started from 1 January 2009 to 31 December 2016. We defined the maintenance period as the period from 6-month after the diagnosis of schizophrenia, which is utilized for the main results. For a total of 44 396 patients with FES, a within-individual Cox regression model was used to compare the risk of the treatment discontinuation and psychiatric hospitalization. Results In group comparison, a long-acting injectable (LAI) antipsychotic group was associated with the lowest risk of the treatment discontinuation (0.64, 0.55–0.75) and psychiatric hospitalization (0.29, 0.22–0.38) in comparison with a typical antipsychotic group and no use, respectively. Among individual antipsychotics, the lowest risk of the treatment discontinuation was observed in LAI paliperidone (0.46, 0.37–0.66) compared to olanzapine. Clozapine was found to be the most effective antipsychotic in lowering the risk of psychiatric hospitalization as monotherapy compared to no use (0.23, 0.18–0.31). Conclusions In real-world patients with FES, LAI paliperidone and clozapine were associated with low treatment discontinuation and better effectiveness in lowering the risk of psychiatric hospitalization.

Objectives: As Ireland confronts the many challenges of broadening the introduction of early intervention services (EIS) for first episode psychosis (FEP) as national policy, this article describes Carepath for Overcoming Psychosis Early (COPE), the EIS of Cavan–Monaghan Mental Health Service, and presents prospective research findings during its first 5 years of operation. Methods: COPE was launched as a rural EIS with an embedded research protocol in early 2012, following an education programme for general practitioners (GPs). Here, operational activities are documented and research findings presented through to late 2016. Results: During this period, 115 instances of FEP were incepted into COPE, 70.4% via their GP and 29.6% via the Emergency Department. The annual rate of inception was 24.8/100,000 of population aged > 15 years and was 2.1-fold more common among men than women. Mean duration of untreated psychosis was 5.7 months and median time from first psychotic presentation to initiation of antipsychotic treatment was zero days. Assessments of psychopathology, neuropsychology, neurology, premorbid functioning, quality of life, insight, and functionality compared across 10 DSM-IV psychotic diagnoses made at six months following presentation indicated minimal differences between them, other than more prominent negative symptoms in schizophrenia and more prominent mania in bipolar disorder. Conclusions: COPE illustrates the actuality of introducing and the challenges of operating a rural EIS for FEP. Prospective follow-up studies of the 5-year COPE cohort should inform on the effectiveness of this EIS model in relation to long-term outcome in psychotic illness across what appear to be arbitrary diagnostic boundaries at FEP.

AbstractBackgroundPoor response to dopaminergic antipsychotics constitutes a major challenge in the treatment of psychotic disorders and markers for non-response during first-episode are warranted. Previous studies have found increased levels of glutamate and γ-aminobutyric acid (GABA) in non-responding first-episode patients compared to responders, but it is unknown if non-responders can be identified using reference levels from healthy controls (HCs).MethodsThirty-nine antipsychotic-naïve patients with first-episode psychosis and 36 matched HCs underwent repeated assessments with the Positive and Negative Syndrome Scale and 3T magnetic resonance spectroscopy. Glutamate scaled to total creatine (/Cr) was measured in the anterior cingulate cortex (ACC) and left thalamus, and levels of GABA/Cr were measured in ACC. After 6 weeks, we re-examined 32 patients on aripiprazole monotherapy and 35 HCs, and after 26 weeks we re-examined 30 patients on naturalistic antipsychotic treatment and 32 HCs. The Andreasen criteria defined non-response.ResultsBefore treatment, thalamic glutamate/Cr was higher in the whole group of patients but levels normalized after treatment. ACC levels of glutamate/Cr and GABA/Cr were lower at all assessments and unaffected by treatment. When compared with HCs, non-responders at week 6 (19 patients) and week 26 (16 patients) had higher baseline glutamate/Cr in the thalamus. Moreover, non-responders at 26 weeks had lower baseline GABA/Cr in ACC. Baseline levels in responders and HCs did not differ.ConclusionGlutamatergic and GABAergic abnormalities in antipsychotic-naïve patients appear driven by non-responders to antipsychotic treatment. If replicated, normative reference levels for glutamate and GABA may aid estimation of clinical prognosis in first-episode psychosis patients.

AimsWe here present preliminary results from our study to understand better the changes in people’ s experience of food in the months after diagnosis with first episode psychosis (FEP). Weight gain often occurs in the weeks/months after diagnosis and is related to an increase in appetite and food intake. Many drugs that are effective in treating psychosis are associated with changes in the way that people experience reward when they eat.The aim of this project is to increase our understanding of exactly why this happens in terms of an individual's experience of food reward and reduced satiety – and therefore how we can help people with FEP to keep their weight down. At this stage we are looking at the feasibility of applying currently available evaluation tools to people in this situation.MethodA convenience sample was used to recruit 10 service users from RDaSH NHS FT Early Intervention Services. This is a feasibility study which will provide data to underpin a fully powered, larger trial.Rating scales applied were:Power of food questionnaire: measures responsiveness to the food environment.Intuitive Eating Scale: measures an individual's tendency to follow their physical hunger and satiety cues.The loss of control over eating scale (LOCES): measures a global sense of whether individuals experience LOC over eating.Dutch Eating Behaviour Questionnaire (DEBQ): measures restrained eating, emotional eating and external eating.ResultThe ages of the participants ranged from 17-26 years. All were started on Olanzapine at the dose of 5 or 10 mg daily.Baseline total scores for the Power of Food (2.47-3.80)/5 (higher score = more responsiveness) and Intuitive Eating scales (2.10-2.62)/5 (higher score = greater tendency to follow hunger and satiety cues) were in the mid-range, while the LOCES scores varied widely from 1.50-2.38/5.The DEBQ restrained subscale score range was 2.40-2.80/5 (higher indicates greater restraint with food) while the DEBQ external subscale ranged from 2.70—3.00/5 (higher = greater tendency to overeat) and the DEBQ emotional subtotal score was 1.92-1.94/5, in keeping with a relatively low emotional drive to eat.ConclusionOur preliminary results reveal at the beginning of antipsychotic treatment a moderate responsiveness to food and tendency to follow hunger/ satiety cues, with scores for Loss of Control of eating in the low to moderate range and a low emotional drive to eat. The difference between these and the follow-up eating behaviour scores will provide important clues as to the precise changes in eating behaviour with anti-psychotic treatment in FEP.
