    • 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 ...

    • Increased complement factor B and Bb levels are associated with mortality in patients with severe aortic stenosis 

      Shahini, Negar; Ueland, Thor; Auensen, Andreas; Michelsen, Annika; Ludviksen, Judith K; Hussain, Amjad Iqbal; Pettersen, Kjell; Aakhus, Svend; Espeland, Torvald; Lunde, Ida Gjervold; Kirschfink, Michael; Nilsson, Per; Mollnes, Tom Eirik; Gullestad, Lars; Aukrust, Pål; Yndestad, Arne; Louwe, Maria Cornelia (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-24)
      Inflammation is involved in initiation and progression of aortic stenosis (AS). However, the role of the complement system, a crucial component of innate immunity in AS, is unclear. We hypothesized that circulating levels of complement factor B (FB), an important component of the alternative pathway, are upregulated and could predict outcome in patients with severe symptomatic AS. Therefore, plasma ...
