Abstract
AIM Relapse rates are very high in schizophrenia. However, little is known about the predictors of the time to relapse other than treatment non-adherence. We investigated possible risk factors for the time to relapse in patients with first-episode schizophrenia (n = 107) who received assured treatment by way of long-acting injectable antipsychotic over 24 months and who underwent regular clinical, cognitive, and metabolic assessments. METHODS Using Cox regression analyses we assessed selected premorbid and baseline potential predictors of time to relapse. Relapse was defined using operationally defined relapse criteria. RESULTS In the primary analysis only neurological soft signs total score retained significance, with higher scores predicting shorter time to relapse (HR = 1.05, 95% CI = 1.01-1.10, p = .029). In a more detailed secondary analysis poorer social relationships predicted shorter time to relapse (HR = 0.85, 95% CI = 0.76-0.95, p = .003). CONCLUSION Our predominantly negative findings suggest that many of the previously implicated risk factors for the time to relapse are mediated by non-adherence rather than having a direct effect on relapse-proneness. Neurological soft signs, and perhaps quality of life in social relationships appear to play a role and merit further investigation.

The association between psychosocial stress, interpersonal sensitivity, social withdrawal and psychosis relapse: a systematic review. SCHIZOPHRENIA (HEIDELBERG, GERMANY) 2023; 9:22. [PMID: 37037858 PMCID: PMC10086007 DOI: 10.1038/s41537-023-00349-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Accepted: 03/15/2023] [Indexed: 04/12/2023]
Abstract
Psychosis is associated with a high risk of relapse, with 67% of clients relapsing within one year following a first episode. In light of the high personal, social, and healthcare costs of the illness, it is paramount to understand the risk factors associated with psychosis relapse. The current systematic review aims to critically review the role of psychosocial stress in psychosis relapse in individuals with an established psychotic disorder. This review systematically searched Ovid (PsycINFO, EMBASE, MEDLINE) literature databases from inception until 28th February 2022. Sixteen studies were eligible for inclusion. Most studies found that individuals with psychosis demonstrate high levels of psychosocial stress and are more likely to be socially withdrawn compared to healthy controls or other clinical presentations. Most studies reported a statistically significant association between psychosocial stress and psychosis relapse, as well as between social withdrawal and psychosis relapse. However, no studies examined the association between high levels of interpersonal sensitivity and psychosis relapse. Individuals with psychosis tend to experience high levels of psychosocial stress and social withdrawal, and these appear to increase the risk of psychosis relapse. Due to high levels of heterogeneity within the literature, we could only conduct a narrative synthesis of the findings. Future studies would benefit from employing a meta-analytic approach.

Association between childhood maltreatment and the clinical course of bipolar disorders: A survival analysis of mood recurrences. Acta Psychiatr Scand 2022; 145:373-383. [PMID: 35080248 DOI: 10.1111/acps.13401] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/18/2021] [Revised: 01/08/2022] [Accepted: 01/16/2022] [Indexed: 12/17/2022]
Abstract
OBJECTIVES Childhood maltreatment, also referred as childhood trauma, increases the severity of bipolar disorders (BD). Childhood maltreatment has been associated with more frequent mood recurrences, however, mostly in retrospective studies. Since scarce, further prospective studies are required to identify whether childhood maltreatment may be associated with the time to recurrence in BD. METHODS Individuals with BD (N = 2008) were assessed clinically and for childhood maltreatment at baseline, and followed up for two years. The cumulative probability of mood recurrence over time was estimated with the Turnbull's extension of the Kaplan-Meier analysis for interval-censored data, including childhood maltreatment as a whole, and then maltreatment subtypes as predictors. Analyses were adjusted for potential confounding factors. RESULTS The median duration of follow-up was 22.3 months (IQR:12.0-24.8). Univariable analyses showed associations between childhood maltreatment, in particular all types of abuses (emotional, physical, and sexual) or emotional neglect, and a shorter time to recurrence (all p < 0.001). When including potential confounders into the multivariable models, the time to mood recurrence was associated with multiple/severe childhood maltreatment (i.e., total score above the 75th percentile) (HR = 1.32 95%CI (1.11-1.57), p = 0.002), and more specifically with moderate/severe physical abuse (HR = 1.44 95%CI(1.21-1.73), p < 0.0001). Living alone, lifetime anxiety disorders, lifetime number of mood episodes, baseline depressive and (hypo)manic symptoms, and baseline use of atypical antipsychotics were also associated with the time to recurrence. CONCLUSIONS In addition to typical predictors of mood recurrences, an exposure to multiple/severe forms of childhood maltreatment, and more specifically to moderate to severe physical abuse, may increase the risk for a mood recurrence in BD. This leads to the recommendations of more scrutiny and denser follow-up of the individuals having been exposed to such early-life stressors.

Abstract
OBJECTIVE Early life adversity is suspected to play an important role for onset and course of psychosis, but its relationship with longer-term clinical outcome is not entirely clear. In this longitudinal study, we investigated the impact of childhood trauma (CT) on positive and negative symptom remission in first episode psychosis (FEP) patients over two years. METHODS A total of 210 FEP patients were assessed with the Childhood Trauma Questionnaire. Patients reporting moderate to severe trauma (CT; N = 114; 54.3%) were compared to those without trauma (N-CT; N = 96; 45.7%). Positive (PSR) and negative symptom remission (NSR) were determined monthly over 24 months following established criteria using the Scale for Assessment of Positive Symptoms and the Scale for Assessment of Negative Symptoms. Global Functioning was evaluated at baseline and 24 months of follow-up. RESULTS Compared to N-CT patients, CT patients had achieved significantly lower rates of PSR at 12 months and significantly lower rates of NSR at 24 months. A dose-response relationship was observed between the number of trauma categories fulfilled and the number of patients not achieving PSR and NSR at these time points. Higher trauma scores were significantly associated with poor functioning and higher positive and negative symptom severity at 24 months, but not at baseline and 12 months of follow-up. CONCLUSION Differential effects of CT on clinical outcome may not be apparent at psychosis onset, but only become evident through poor symptomatic remission and general functioning over time. Targeted diagnostic and therapeutic efforts after illness onset might limit these detrimental consequences.

Abstract
AIM The trauma-psychosis cycle proposes an interactive relationship between impaired developmental and cognitive trajectory, childhood trauma exposure, and increased risk for psychosis. This study explored how childhood trauma (CT) and atypical development (AD) impact clinical course in an early psychosis cohort. METHODS A retrospective chart review of behavioural and clinical research data was conducted with individuals ages 12 to 40 (N = 508; 72.4% males) evaluated by an early psychosis program. RESULTS CT exposure was associated with earlier onset of full threshold psychosis, more hospitalizations, higher ratings of negative symptoms, and increased likelihood of engaging in suicidal behaviour. AD alone was associated with earlier onset of psychosis symptoms, higher ratings of negative symptoms and greater likelihood of engaging in non-suicidal self-injury. The combination of CT and AD was associated with the earliest symptom onset and poorest psychosocial functioning. CONCLUSIONS The findings contribute to our understanding of heterogeneity in the early psychosis population and highlight the specific risk factors that could be targets in treatment.

Abstract
Relapse rates among individuals with psychotic disorders are high. In addition to the financial burden placed on clinical services, relapse is associated with worse long-term prognosis and poorer quality of life. Robust evidence indicates that stressful life events commonly precede the onset of the first psychotic episode; however, the extent to which they are associated with relapse remains unclear. The aim of this systematic review is to summarize available research investigating the association between recent stressful life events and psychotic relapse or relapse of bipolar disorder if the diagnosis included psychotic symptoms. PsycINFO, Medline and EMBASE were searched for cross-sectional, retrospective and prospective studies published between 01/01/1970 and 08/01/2020 that investigated the association between adult stressful life events and relapse of psychosis. Study quality was assessed using the Effective Public Health Practice Project guidelines. Twenty-three studies met eligibility criteria (prospective studies: 14; retrospective studies: 6; cross-sectional: 3) providing data on 2046 participants in total (sample size range: 14-240 participants). Relapse was defined as a return of psychotic symptoms (n = 20), a return of symptoms requiring hospitalization (n = 2) and a return of symptoms or hospitalization (n = 1). Adult stressful life events were defined as life events occurring after the onset of psychosis. Stressful life events included but were not limited to adult trauma, bereavement, financial problems and conflict. Eighteen studies found a significant positive association between adult stressful life events and psychotic relapse and five studies found a non-significant association. We conclude that adult stressful life events, occurring after psychosis onset, appear to be associated with psychotic relapse.

Childhood trauma and being at-risk for psychosis are associated with higher peripheral endocannabinoids. Psychol Med 2020; 50:1862-1871.

Abstract
BACKGROUND Evidence has been accumulating regarding alterations in components of the endocannabinoid system in patients with psychosis. Of all the putative risk factors associated with psychosis, being at clinical high-risk for psychosis (CHR) has the strongest association with the onset of psychosis, and exposure to childhood trauma has been linked to an increased risk of development of psychotic disorder. We aimed to investigate whether being at-risk for psychosis and exposure to childhood trauma were associated with altered endocannabinoid levels. METHOD We compared 33 CHR participants with 58 healthy controls (HC) and collected information about previous exposure to childhood trauma as well as plasma samples to analyse endocannabinoid levels. RESULTS Individuals with both CHR and experience of childhood trauma had higher N-palmitoylethanolamine (p < 0.001) and anandamide (p < 0.001) levels in peripheral blood compared to HC and those with no childhood trauma. There was also a significant correlation between N-palmitoylethanolamine levels and symptoms as well as childhood trauma. CONCLUSIONS Our results suggest an association between CHR and/or childhood maltreatment and elevated endocannabinoid levels in peripheral blood, with a greater alteration in those with both CHR status and history of childhood maltreatment compared to those with either of those risks alone. Furthermore, endocannabinoid levels increased linearly with the number of risk factors and elevated endocannabinoid levels correlated with the severity of CHR symptoms and extent of childhood maltreatment. Further studies in larger cohorts, employing longitudinal designs are needed to confirm these findings and delineate the precise role of endocannabinoid alterations in the pathophysiology of psychosis.

Abstract
INTRODUCTION Different types of childhood trauma have been repeatedly shown to contribute to psychotic symptoms. Gender differences in schizophrenia are well known. Some studies argue that trauma history means a significantly higher risk of psychosis for women than men. However, there is evidence of early adverse life events to be associated with higher stress-sensitivity in men. Little is known about the connection of specific type of trauma and specific psychotic symptoms as well as the course of illness with explicit regard to gender differences. METHODS 102 men and women with schizophrenia spectrum disorder were tested using Structured Clinical Interview for DSM-IV-TR Axis I Disorders, Scale for Assessing Positive Symptoms, Early Trauma Inventory-SR. RESULTS Although, women had a later age at onset without regarding trauma history (d = 0.74), this difference became non-significant when introducing trauma variables. Patients reporting physical abuse had a significantly earlier age at onset, regardless of their sex (V = 0.13, F = 3.11, p = 0.03. Physical abuse predicted an earlier age at onset only in women (R2 = 0.23). History of general trauma predicted more frequent hospitalizations only in men (R2 = 0.55). CONCLUSIONS Although women generally tend to have a more favorable course of illness including a later age at onset men, women with CPA seem to lose this "advantage". It is necessary to investigate the contribution of gender interacting with adverse life events in contribution to the phenomenology and etiology of schizophrenia.

Abstract
Exposure to childhood trauma has been associated with psychotic symptoms, being at ultra-high risk for psychosis (UHR), and psychotic disorders such as schizophrenia. Negative self-beliefs have been shown to partially mediate the relationship between childhood trauma and paranoia and have been shown to be characteristic of patients with psychosis. However, whether the association between childhood trauma and being at high risk of developing psychosis (e.g., UHR) and paranoia symptoms is mediated by altered cognitive schema is unknown and warrants investigation to inform preventive interventions. Data was collected on 30 UHR patients from Outreach and Support in South London about exposure to childhood trauma, cognitive schema, paranoia and cannabis use. Relative to healthy controls (n = 38), UHR patients were significantly more likely to report exposure to various types of childhood trauma (emotional and sexual abuse, and emotional and physical neglect), had more negative schema and less positive schema about themselves and others, and were more likely to use cannabis more than once a month. Emotional neglect was found to be significantly associated with UHR status even after controlling for the effects of previous exposure to cannabis use (b = 0.262, 95% CI: 0.115-0.408), and this association was partially mediated by negative self-schema (b = 0.045, 95% CI: 0.004-0.159). Similarly, emotional neglect was significantly associated with paranoia (b = 1.354, 95% CI: 0.246-2.462), and this association was partially mediated by negative self-schema (b = 0.988, 95% CI: 0.323-1.895). These findings provide preliminary evidence about the cognitive mechanisms that may underlie the association between childhood trauma and later risk for psychosis.
