      Background: Schizophrenia (SCZ) and bipolar disorder (BD) are severe mental illnesses (SMI) associated with elevated cardiovascular disease (CVD) risk, including obesity. Leptin and adiponectin are secreted by adipose tissue, with pro- and anti-inflammatory properties, respectively. The second generation antipsychotics (AP) olanzapine, clozapine, and quetiapine have been associated with high leptin ...

      <p><i>Background:</i> Cardiovascular disease (CVD) is a major cause of premature death in patients with psychotic disorders, where dyslipidemia occurs frequently. In the pathogenesis of these serious mental disorders, a low-grade inflammation seems to be a possible contributor. Concurrently, systemic inflammation and its interplay with dyslipidemia is a central driver in the pathogenesis of CVD. We ...
    • Increased Interleukin 18 Activity in Adolescents With Early-Onset Psychosis Is Associated With Cortisol and Depressive Symptoms 

      Wedervang-Resell, Kirsten; Friis, Svein; Lonning, Vera Louise Hiorth; Smelror, Runar; Johannessen, Cecilie Haggag; Reponen, Elina Johanna; Lyngstad, Siv Hege; Lekva, Tove; Aukrust, Pål; Ueland, Thor; Andreassen, Ole Andreas; Agartz, Ingrid; Myhre, Anne Margrethe (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-14)
      <i>Objective</i> - Evidence indicates that the pathophysiology of adult psychosis involves immune dysregulation, but its associations with stress are often not considered. The inflammatory cytokine interleukin (IL)-18, which is elevated in adult schizophrenia, is suggested to be sensitive to stress. We compared the associations of IL-18 with cortisol and clinical variables in adolescents with ...
    • Polygenic risk for schizophrenia and bipolar disorder in relation to cardiovascular biomarkers 

      Reponen, Elina Johanna; Ueland, Thor; Rokicki, Jaroslav; Bettella, Francesco; Aas, Monica; Werner, Maren C. F.; Dieset, Ingrid; Steen, Nils E.; Andreassen, Ole A.; Tesli, Martin Steen (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-05)
      Individuals with schizophrenia and bipolar disorder are at an increased risk of cardiovascular disease (CVD), and a range of biomarkers related to CVD risk have been found to be abnormal in these patients. Common genetic factors are a putative underlying mechanism, alongside lifestyle factors and antipsychotic medication. However, the extent to which the altered CVD biomarkers are related to genetic ...
    • Reduced brain-derived neurotrophic factor is associated with childhood trauma experiences and number of depressive episodes in severe mental disorders 

      Aas, Monica; Dieset, Ingrid; Mørch, Ragni Helene; Steen, Nils Eiel; Hope, Sigrun; Reponen, Elina Johanna; Anderssen, Jannicke Fjæra; Ueland, Thor; Aukrust, Pål; Melle, Ingrid; Agartz, Ingrid; Andreassen, Ole Andreas (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-17)
      <p><i>Background - </i>Although several studies have found reduced plasma BDNF levels in patients with severe mental disorders, the sample sizes have been small and have exhibited variation and heterogeneity. Furthermore, long-term neurobiological changes following childhood trauma and clinical severity have been linked to a reduction in BDNF levels. Accordingly, we aim to clarify, using the largest ...
