Pathways to care, DUP, and types of interventions over 5 years following psychosis onset: findings from a naturalistic study conducted in routine generalist mental health services

Pathways to care: Source of referral at first-episode psychosis, a cross-country comparison between Bologna and South London

OBJECTIVES

Pathways to Care (PtC) are useful indicators of how patients access mental healthcare, especially in the context of first-episode psychosis (FEP). We explored how PtC: source of referral, is associated with patients' characteristics and clinical presentation and assessed the cross-country differences of the PtC predictors between South London and Bologna.

METHODS

This study included 427 FEP individuals in the context of the European Union Gene-Environment Interactions (EU-GEI) study. We performed multinomial logistic regression to test the associations between our outcome variables (PtC) and the independent study variables.

RESULTS

In London, patients were more likely to be referred by GPs or specialists, while in Bologna, most patients followed the emergency route. Despite the study centre differences, older patients were more likely to be referred by GPs; patients referred informally and via specialist services were more likely to be single. Compared with emergency referrals, patients referred by GPs and specialists experienced a longer DUP. We found insufficient evidence of an association between symptoms profile and PtC.

CONCLUSIONS

PtC characteristics of FEP patients were associated with several sociodemographic and DUP in both study centres. Our results highlight the importance of social networks and social services and public engagement, and public health initiatives (such as psychoeducation in schools and leisure centres) in easing help-seeking behaviours.

Disorganization in first episode affective psychosis: Treatment response and clinical considerations from a 2-year follow-up study in a "real world" setting

INTRODUCTION

Disorganization is a crucial domain in affective psychoses. However, it has received poor research attention, especially at the illness onset. The aims of this study were: (a) to monitor the longitudinal course of disorganization in young people with first episode affective psychosis (FEAP) across 2 years of follow-up, and (b) to investigate any relevant correlation of disorganized symptoms with psychopathology, functioning and the specific treatment elements of an "Early Intervention in Psychosis" (EIP) protocol along the follow-up period.

MATERIALS AND METHODS

Seventy-five FEAP participants (aged 12-35 years) completed the Positive And Negative Syndrome Scale (PANSS) and the Global Assessment of Functioning (GAF). Spearman's rank correlation coefficients were calculated.

RESULTS

During the follow-up, disorganized symptoms showed significant enduring positive correlations with PANSS items representing delusional thought content and uncooperativeness, as well as a persistent negative association with the GAF score. Across the 2-year follow-up period, FEAP individuals also had a relevant reduction in disorganization levels. This symptom decrease was specifically related with the combination of antipsychotic medication with the specific psychosocial components of our EIP intervention offered to FEAP patients during the first 12 months of treatment.

CONCLUSIONS

Disorganization is relevant in FEAP subjects already at their enrollment in specialized EIP protocols. However, it decreases over time, together with the delivery of specific, combined (person-tailored) EIP interventions.

Machine learning based prediction and the influence of complement - Coagulation pathway proteins on clinical outcome: Results from the NEURAPRO trial

BACKGROUND

Functional outcomes are important measures in the overall clinical course of psychosis and individuals at clinical high-risk (CHR), however, prediction of functional outcome remains difficult based on clinical information alone. In the first part of this study, we evaluated whether a combination of biological and clinical variables could predict future functional outcome in CHR individuals. The complement and coagulation pathways have previously been identified as being of relevance to the pathophysiology of psychosis and have been found to contribute to the prediction of clinical outcome in CHR participants. Hence, in the second part we extended the analysis to evaluate specifically the relationship of complement and coagulation proteins with psychotic symptoms and functional outcome in CHR.

MATERIALS AND METHODS

We carried out plasma proteomics and measured plasma cytokine levels, and erythrocyte membrane fatty acid levels in a sub-sample (n = 158) from the NEURAPRO clinical trial at baseline and 6 months follow up. Functional outcome was measured using Social and Occupational Functional assessment Score (SOFAS) scale. Firstly, we used support vector machine learning techniques to develop predictive models for functional outcome at 12 months. Secondly, we developed linear regression models to understand the association between 6-month follow-up levels of complement and coagulation proteins with 6-month follow-up measures of positive symptoms summary (PSS) scores and functional outcome.

RESULTS AND CONCLUSION

A prediction model based on clinical and biological data including the plasma proteome, erythrocyte fatty acids and cytokines, poorly predicted functional outcome at 12 months follow-up in CHR participants. In linear regression models, four complement and coagulation proteins (coagulation protein X, Complement C1r subcomponent like protein, Complement C4A & Complement C5) indicated a significant association with functional outcome; and two proteins (coagulation factor IX and complement C5) positively associated with the PSS score. Our study does not provide support for the utility of cytokines, proteomic or fatty acid data for prediction of functional outcomes in individuals at high-risk for psychosis. However, the association of complement protein levels with clinical outcome suggests a role for the complement system and the activity of its related pathway in the functional impairment and positive symptom severity of CHR patients.

Sex Differences in Bipolar Disorders: Impact on Psychopathological Features and Treatment Response

INTRODUCTION

Sex differences were demonstrated in bipolar disorders (BD) concerning epidemiological, clinical, and psychopathological characteristics, but consensus is lacking. Moreover, data concerning the influence of sex on treatment response in BD is contrasting. The present cross-sectional study aimed to analyze sex differences in a population of BD subjects, with specific focus on psychopathological features and treatment response.

MATERIALS AND METHODS

Subjects diagnosed with BD according to the Diagnostic and Statistical Manual of Mental Disorders, 5th version (DSM-5) were recruited. Socio-demographic and clinical characteristics were collected. The Hamilton Rating Scale for Depression, the Mania Rating Scale (MRS), the brief version of the Temperament Evaluation of Memphis, Pisa and San Diego-Münster version (briefTEMPS-M), and the Barratt Impulsiveness Scale-11 items (BIS-11) were used for psychopathological assessment. Treatment response was appraised with the Alda Scale. We performed bivariate analyses to compare socio-demographic, clinical, and psychopathological characteristics between men and women (p < 0.05). A logistic regression was run to analyze features that were significantly associated with female sex.

RESULTS

Among the recruited 219 BD subjects, 119 (54.3%) were females. Women had a lower scholarity (p = 0.015) and were less frequently employed (p = 0.001). As for psychopathological features, a higher MRS total score (p < 0.001) was detected among women, as well as higher BIS-11 total score (p = 0.040), and briefTEMPS-M score for anxious temperament (p = 0.006). Men showed higher prevalence of DSM-5 mixed features (p = 0.025), particularly during a depressive episode (p = 0.014). Women reported longer duration of untreated illness (DUI) (p < 0.001). There were no sex differences in the Alda Scale total score when considering the whole sample, but this was significantly higher among men (p = 0.030) when evaluating subjects treated with anticonvulsants. At the logistic regression, female sex was positively associated with longer DUI (p < 0.001; OR 1.106, 95% CI 1.050-1.165) and higher MRS total score (p < 0.001; OR 1.085, 95% CI 1.044-1.128) and negatively associated with employment (p = 0.003; OR 0.359, 95% CI 0.185-0.698) and DSM-5 mixed features (p = 0.006; OR 0.391, 95% CI 0.200-0.762).

CONCLUSIONS

The clinical presentation of BD may differ depending on sex. The severity of BD should not be neglected among women, who may also display worse treatment response to anticonvulsants.

The 'Parma-Early Psychosis' programme: Characterization of help-seekers with first episode psychosis

AIM

Research on early psychosis paradigm has demonstrated the importance of early intervention (EI) in reducing illness severity and persistence. From January 2013, the Parma Department of Mental Health developed a specific care pathway [the 'Parma-Early Psychosis' (Pr-EP) programme] as a diffused EI infrastructure aimed to offer an evidence-based protocol of care to help-seekers with a first episode psychosis (FEP). Aim of this study was to investigate sources of referral, drop-out rate, sociodemographic and clinical characteristics of patients enrolled in the Pr-EP programme during the first 6 years of activity.

METHODS

Participants (n = 279) were individuals (aged 12-54 years) completing an ad-hoc socio-demographic/clinical schedule.

RESULTS

At baseline, the most frequent diagnoses were schizophreniform disorder (30.5%) and schizophrenia (29.4%). Only 31 (11.1%) subjects dropped out during the first year of treatment. FEP participants were mainly referred by general practitioners (36.9%) and emergency room/general hospital (28.7%). FEP individuals who were referred by emergency room/general hospital showed a higher percentage of current suicidal ideation compared to those entering the Pr-EP protocol through other sources of referrals.

CONCLUSIONS

EI in FEP help-seekers within Italian public mental health services is feasible and desirable, also in adolescence, where the risk of falling through the child-adult service gap is high.
