The impact of parent history of severe mental illness on schizophrenia outcomes: results from the real-world FACE-SZ cohort.

Parent history of severe mental illness (PHSMI) may have long-term consequences in adult offspring due to genetic and early environmental factors in preliminary studies. To compare the outcomes associated in subjects with PHSMI to those in patients without PHSMI. The participants with schizophrenia and schizoaffective disorders were recruited in the ongoing FACE-SZ cohort at a national level (10 expert centers) and evaluated with a 1-day-long standardized battery of clinician-rated scales and patient-reported outcomes. PHSMI was defined as history of schizophrenia or bipolar disorders in at least one parent and was included as explanatory variable in multivariate models. Of the 724 included patients, 78 (10.7%) subjects were classified in the PHSMI group. In multivariate analyses, PHSMI patients had a better insight into schizophrenia and the need for treatment and reported more often childhood trauma history compared to patients without PHSMI. More specifically, those with paternal history of SMI reported more severe outcomes (increased childhood physical and emotional abuses, comorbid major depression and psychiatric hospitalizations). PHSMI is associated with increased risk of childhood trauma, major depressive disorder and psychiatric hospitalization and better insight in individuals with schizophrenia. Specific public health prevention programs for parents with SMI should be developed to help protect children from pejorative psychiatric outcomes. PHSMI may also explain in part the association between better insight and increased depression in schizophrenia.

Early-life factors associated with increased risk of disability pension in the national real-world schizophrenia FACE-SZ cohort study.

Among severe psychiatric disorders, schizophrenia has one of the highest impacts on professional and personal functioning with important indirect costs including disability pension allowance for the patients with the more severe forms of schizophrenia. To explore early-life factors associated with disability pension in schizophrenia. 916 patients were consecutively recruited at a national level in 10 expert centers and received a comprehensive standardized evaluation. Their disability pension status and early-life variables were reported from medical records and validated scales. Eight factors were explored: age, male sex, parental history of severe mental illness, childhood trauma exposure, education level, childhood ADHD, early age at schizophrenia onset and duration of untreated psychosis. 739 (80.7%) participants received a disability pension. In the multivariate model, early age at schizophrenia onset and low education level were associated with disability pension independently of age and sex while no significant association was found for parent history of severe mental illness, childhood trauma, childhood ADHD or duration of untreated psychosis. Low education level and early age at schizophrenia onset seem the best predictors of increased risk of disability pension in schizophrenia.

Redefining peripheral inflammation signature in schizophrenia based on the real-world FACE-SZ cohort.

BACKGROUND: Peripheral inflammation is associated with impaired prognosis in schizophrenia (SZ). Highly sensitive C-reactive protein (hs-CRP) is the most used inflammatory biomarker in daily practice. However, no consensual cut-off has been determined to date to discriminate patients with peripheral inflammation from those without. AIMS: To determine if patients with peripheral inflammation between 1 and 3 mg/L had poorer outcomes compared to those with undetectable CRP (<1 mg/L). METHOD: Consecutive participants of the FACE-SZ cohort with a hs-CRP < 3 mg/L were included in 10 expert academic centers with a national geographical distribution between 2010 and 2018. Potential sources of inflammation, socio-demographics, illness characteristics, current illness severity, functioning and quality of life and were reported following the FACE-SZ standardized protocol. RESULTS: 580 patients were included, of whom 226 (39%) were identified with low-grade inflammation defined by a hs-CRP between 1 and 3 mg/L. Overweight and lack of dental care were identified as potential sources of inflammation. After adjustment for these factors, patients with inflammation had more severe psychotic, depressive and aggressive symptomatology and impaired functioning compared to the patients with undetectable hs-CRP. No association with tobacco smoking or physical activity level has been found. CONCLUSIONS: Patients with schizophrenia with hs-CRP level between 1 and 3 mg/L should be considered at risk for inflammation-associated disorders. Lowering weight and increasing dental care may be useful strategies to limit the sources of peripheral inflammation. Hs-CRP > 1 mg/L is a reliable marker to detect peripheral inflammation in patients with schizophrenia.
