OBJECTIVE Severe mental disorder and cardiovascular disease (CVD) are often associated, and inflammation is implicated in both disorders. We investigated whether there is a relationship between CVD risk factors and inflammation in schizophrenia or bipolar disorder, and if second generation antipsychotics (SGA) interact. METHODS We included 361 patients in(More)
BACKGROUND Previous studies suggest elevated inflammation in schizophrenia and bipolar disorder, with increased activity of the Interleukin 1 (IL-1), interleukin 6 (IL-6), tumor necrosis factor (TNF)-alpha, von Willebrand factor (vWf) and osteoprotegerin (OPG). It is unclear how immune activation is involved in the psychopathology. We investigated if(More)
OBJECTIVE The hypothalamic-pituitary-adrenal (HPA) axis seems dysregulated and part of the pathophysiology in bipolar disorder and schizophrenia, but the underlying mechanisms are unknown. Recent evidence indicates that systemic cortisol metabolism influences blood cortisol levels and HPA axis functioning. Our objective was to estimate systemic cortisol(More)
OBJECTIVE Elevated levels of inflammation are reported in bipolar disorders (BP), but how this relates to affective symptoms is unclear. We aimed to determine if immune markers that consistently have been reported elevated in BP were associated with depressive and manic symptoms, and if this was specific for BP. METHODS From a catchment area, 112 BP(More)
BACKGROUND The mechanisms underlying cognitive impairment in schizophrenia and bipolar disorders are largely unknown. Immune abnormalities have been found in both disorders, and inflammatory mediators may play roles in cognitive function. We investigated if inflammatory markers are associated with general cognitive abilities. METHODS Participants with(More)
BACKGROUND Severe mental disorders are associated with elevated levels of inflammatory markers. In the present study, we investigated whether osteoprotegerin (OPG), a member of the tumour necrosis factor receptor family involved in calcification and inflammation, is elevated in patients with severe mental disorders. METHODS We measured the plasma levels(More)
OBJECTIVE Immunopathogenic mechanisms have been implicated in schizophrenia and bipolar disorder, and genome-wide association studies (GWAS) point to the major histocompatibility complex, a region that contains many immune-related genes. One of the strongest candidate risk genes for schizophrenia and bipolar disorder is the NOTCH4 gene within the major(More)
BACKGROUND Inflammation and immune activation have been implicated in the pathophysiology of severe mental disorders. Previous studies of inflammatory markers, however, have been limited with somewhat inconsistent results. AIMS We aimed to determine the effect sizes of inflammatory marker alterations across diagnostic groups of the psychosis continuum and(More)
OBJECTIVE Our objective was to examine the cortisol release during a mental challenge in severe mental disorders versus healthy controls (HC), analyzing effects of sex, clinical characteristics and medication, and comparing Bipolar Disorder (BD) to Schizophrenia (SCZ). METHODS Patients with BD and SCZ (n=151) were recruited from a catchment area. HC(More)
BACKGROUND Increased inflammation, endothelial dysfunction, and structural brain abnormalities have been reported in both schizophrenia and bipolar disorder, but the relationships between these factors are unknown. We aimed to identify associations between markers of inflammatory and endothelial activation and structural brain variation in psychotic(More)
