      Background: Results showing that sera from double vaccinated individuals have minimal neutralizing activity against Omicron have been interpreted as indicating the need for a third vaccine dose for protection. However, there is little information about early immune responses to Omicron infection in double vaccinated individuals.<p> <p>Methods: We measured inflammatory mediators, antibodies to the ...
    • Circulating markers of extracellular matrix remodelling in severe COVID-19 patients 

      Murphy, Sarah Louise Mikalsen; Halvorsen, Bente; Holter, Jan Cato; Huse, Camilla; Tveita, Anders; Trøseid, Marius; Hoel, Hedda; Kildal, Anders Benjamin; Holten, Aleksander Rygh; Lerum, Tøri Vigeland; Skjønsberg, Ole Henning; Michelsen, Annika Elisabet; Aaløkken, Trond Mogens; Tonby, Kristian; Lind, Andreas; Dudman, Susanne Gjeruldsen; Granerud, Beathe Kiland; Heggelund, Lars; Bøe, Simen; Dyrholt-Riise, Anne Ma; Aukrust, Pål; Barratt-Due, Andreas; Ueland, Thor; Dahl, Tuva Børresdatter (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-17)
      Background Abnormal remodelling of the extracellular matrix (ECM) has generally been linked to pulmonary inflammation and fibrosis and may also play a role in the pathogenesis of severe COVID-19. To further elucidate the role of ECM remodelling and excessive fibrogenesis in severe COVID-19, we examined circulating levels of mediators involved in various aspects of these processes in COVID-19 ...
    • Cytokine pattern in patients with ST-elevation myocardial infarction treated with the interleukin-6 receptor antagonist tocilizumab 

      Woxholt, Sindre; Ueland, Thor; Aukrust, Pål; Anstensrud, Anne Kristine; Broch, Kaspar; Tøllefsen, Ingvild Maria; Ryan, Liv; Bendz, Bjørn; Hopp, Einar; Kløw, Nils-Einar; Seljeflot, Ingebjørg; Halvorsen, Bente; Dahl, Tuva Børresdatter; Huse, Camilla; Andersen, Geir Øystein; Gullestad, Lars; Wiseth, Rune; Amundsen, Brage H.; Damås, Jan Kristian; Kleveland, Ola (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08-17)
      Background - Tocilizumab improves myocardial salvage index (MSI) in patients with ST-elevation myocardial infarction (STEMI), but its mechanisms of action are unclear. Here, we explored how cytokines were affected by tocilizumab and their correlations with neutrophils, C-reactive protein (CRP), troponin T, MSI and infarct size.<p> <p>Methods - STEMI patients were randomised to receive a single ...
    • Endonuclease v regulates atherosclerosis through c-c motif chemokine ligand 2-mediated monocyte infiltration

      BACKGROUND: In cardiovascular diseases, atherosclerotic disorder are the most frequent and important with respect to morbidity and mortality. Inflammation mediated by immune cells is central in all parts of the atherosclerotic progress, and further understanding of the underlying mechanisms is needed. Growing evidence suggests that deamination of adenosine-toinosine in RNA is crucial for a correct ...
    • Interleukin-6 inhibition in ST-elevation myocardial infarction: Immune cell profile in the randomised ASSAIL-MI trial 

      Huse, Camilla; Anstensrud, Anne Kristine; Michelsen, Annika Elisabet; Ueland, Thor; Broch, Kaspar; Woxholt, Sindre; Yang, Kuan; Sharma, Kapil Kishore; Tøllefsen, Ingvild Maria; Bendz, Bjørn; Amundsen, Brage H.; Damås, Jan Kristian; Berg, Erlend Sturle; Bjørkelund, Elisabeth; Quiles-Jiménez, Ana M T; Bjerkeli, Vigdis; Bendz, Christina; Kleveland, Ola; Stensæth, Knut Haakon; Opdahl, Anders; Kløw, Nils-Einar; Andersen, Geir Øystein; Wiseth, Rune; Halvorsen, Bente; Gullestad, Lars; Seljeflot, Ingebjørg; Aukrust, Pål; Osnes, Liv T. N.; Dahl, Tuva Børresdatter (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-30)
      Background We recently showed that interleukin (IL)-6 inhibition by tocilizumab improves myocardial salvage in ST-elevation myocardial infarction (STEMI). However, the mechanisms for this effect are not clear.<p> <p>Methods In this exploratory sub-study of the ASSAIL-MI trial, we examined leukocyte differential counts and their relation to myocardial salvage and peak troponin T (TnT) in STEMI ...
