    • The Alternative Complement Pathway Is Activated Without a Corresponding Terminal Pathway Activation in Patients With Heart Failure 

      Shahini, Negar; Bjørkelund, Elisabeth; Bendz, Christina; Massey, Richard J; Schjalm, Camilla; Halvorsen, Bente; Broch, Kaspar; Ueland, Thor; Gullestad, Lars; Nilsson, Per H.; Aukrust, Pål; Mollnes, Tom Eirik; Louwe, Maria Cornelia; Holt, Margrethe Flesvig; Michelsen, Annika E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-12-24)
      Objective: Dysregulation of the complement system has been described in patients with heart failure (HF). However, data on the alternative pathway are scarce and it is unknown if levels of factor B (FB) and the C3 convertase C3bBbP are elevated in these patients. We hypothesized that plasma levels of FB and C3bBbP would be associated with disease severity and survival in patients with ...

    • The alternative complement pathway is dysregulated in patients with chronic heart failure 

      Shahini, Negar; Michelsen, Annika E.; Nilsson, Per H.; Ekholt, Karin; Gullestad, Lars; Broch, Kaspar; Dahl, Christen P.; Aukrust, Pål; Ueland, Thor; Mollnes, Tom Eirik; Yndestad, Arne; Louwe, Mieke C. (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-02-14)
      The complement system, an important arm of the innate immune system, is activated in heart failure (HF). We hypothesized that HF patients are characterized by an imbalance of alternative amplification loop components; including properdin and complement factor D and the alternative pathway inhibitor factor H. These components and the activation product, terminal complement complex (TCC), were measured ...

    • Leptin and adiponectin as predictors of cardiovascular risk after gestational diabetes mellitus 

      Lekva, Tove; Michelsen, Annika E.; Aukrust, Pål; Henriksen, Tore; Jens, Bollerslev; Ueland, Thor (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-01-10)
      Background: Gestational diabetes mellitus (GDM) is a significant risk factor for cardiovascular disease (CVD) in later life, but the mechanism remains unclear. Adipokine imbalance in the presence of metabolic dysfunction may be a key event in promoting CVD. The aim of the study was to examine the relationships between GDM, cardiovascular risk, and plasma adiponectin, leptin and the leptin/adiponectin ...

    • Prediction of gestational diabetes mellitus and pre-diabetes 5 years postpartum using 75 g oral glucose tolerance test at 14-16 Weeks' gestation 

      Lekva, Tove; Godang, Kristin; Michelsen, Annika E.; Qvigstad, Elisabeth; Normann, Kjersti R.; Norwitz, Errol R.; Tore, Henriksen; Bollerslev, Jens; Roland, Marie; Ueland, Thor (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-06)
      Early detection and treatment of women at risk for gestational diabetes mellitus (GDM) could improve perinatal and long-term outcomes in GDM women and their offspring. We explored if a 75 g oral glucose tolerance test (OGTT) at 14-16 weeks of gestation could identify women who will (1) develop GDM or give birth to large-for-gestational-age (LGA) babies in 1031 pregnant women from the STORK study ...

    • Wnt5a is associated with right ventricular dysfunction and adverse outcome in dilated cardiomyopathy 

      Abraityte, Aurelija; Lunde, Ida Gjervold; Askevold, Erik Tandberg; Michelsen, Annika E.; Christensen, Geir Arve; Aukrust, Pål; Yndestad, Arne; Fiane, Arnt; Andreassen, Arne; Aakhus, Svend; Dahl, Christen Peder; Gullestad, Lars; Broch, Kaspar; Ueland, Thor (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-14)
      The Wingless (Wnt) pathway has been implicated in the pathogenesis of dilated cardiomyopathy (DCM). To explore the role of Wnt modulators Wnt5a and sFRP3 in DCM patients we analyzed the expression of Wnt5a and sFRP3 in plasma and myocardium of DCM patients and evaluated their effects on NFAT luciferase activity in neonatal mouse cardiomyocytes. Elevated circulating Wnt5a (n = 102) was associated ...
