Elevated markers of gut leakage and inflammasome activation in COVID-19 patients with cardiac involvement
Hoel, Hedda Benedicte; Heggelund, Lars; Reikvam, Dag Henrik; Stiksrud, Birgitte; Ueland, Thor; Michelsen, Annika; Otterdal, Kari; Muller, Karl Erik; Lind, Andreas; Müller, Fredrik; Dudman, Susanne Gjeruldsen; Aukrust, Pål; Dyrhol-Riise, Anne Ma; Holter, Jan Cato; Trøseid, Marius (Journal article; Peer reviewed, 2021)Background A high proportion of COVID‐19 patients have cardiac involvement, even those without known cardiac disease. Downregulation of angiotensin converting enzyme 2 (ACE2), a receptor for SARS‐CoV‐2 and the renin‐angiotensin ... -
Hepcidin and Ferritin Predict Microbial Etiology in Community-Acquired Pneumonia
Oppen, Kjersti; Ueland, Thor; Siljan, William Ward; Skadberg, Øyvind; Brede, Cato; Lauritzen, Trine; Aukrust, Pål; Steinsvik, Trude; Husebye, Einar; Michelsen, Annika; Holter, Jan Cato; Heggelund, Lars (Journal article; Peer reviewed, 2021)Background Iron is crucial for survival and growth of microbes. Consequently, limiting iron availability is a human antimicrobial defense mechanism. We explored iron and iron-related proteins as potential biomarkers in ... -
Inflammation markers in multiple sclerosis: CXCL16 reflects and may also predict disease activity
Holmøy, Trygve; Løken-Amsrud, Kristin Ingeleiv; Bakke, Jacob; Beiske, Antonie Giæver; Bjerve, Kristian S; Hovdal, Harald Olav; Lilleås, Finn; Midgard, Rune; Pedersen, Tom; Saltyte Benth, Jurate; Torkildsen, Øivind; Wergeland, Stig; Myhr, Kjell-Morten; Michelsen, Annika; Aukrust, Pål; Ueland, Thor (Peer reviewed; Journal article, 2013-09-19)Background. Serum markers of inflammation are candidate biomarkers in multiple sclerosis (MS). ω-3 fatty acids are suggested to have anti-inflammatory properties that might be beneficial in MS. We aimed to explore the ... -
Plasma levels of interleukin 27 in falciparum malaria is increased independently of co-infection with HIV: potential immune-regulatory role during malaria
Otterdal, Kari; Berg, Åse; Michelsen, Annika; Patel, Sam; Gregersen, Ida; Sagen, Ellen Lund; Halvorsen, Bente; Yndestad, Arne; Ueland, Thor; Langeland, Nina; Aukrust, Pål (Journal article; Peer reviewed, 2020)Background The immune response during falciparum malaria mediates both harmful and protective effects on the host; however the participating molecules have not been fully defined. Interleukin (IL)-27 is a pleiotropic ... -
Rifaximin alters gut microbiota profile, but does not affect systemic inflammation - a randomized controlled trial in common variable immunodeficiency
Jørgensen, Silje Fjellgård; Macpherson, Magnhild Eide; Bjørnetrø, Tonje; Holm, Kristian; Kummen, Martin; Rashidi, Azita; Michelsen, Annika; Lekva, Tove; Halvorsen, Bente; Trøseid, Marius; Mollnes, Tom Eirik; Berge, Rolf Kristian; Yndestad, Arne; Ueland, Thor; Karlsen, Tom Hemming; Aukrust, Pål; Hov, Johannes Espolin Roksund; Fevang, Børre (Peer reviewed; Journal article, 2019-01-17)Common variable immunodefciency (CVID) patients have reduced gut microbial diversity compared to healthy controls. The reduced diversity is associated with gut leakage, increased systemic infammation and ten “key” bacteria ... -
Soluble markers of neutrophil, T-cell and monocyte activation are associated with disease severity and parasitemia in falciparum malaria
Otterdal, Kari; Berg, Åse; Michelsen, Annika; Patel, Sam; Tellevik, Marit Gjerde; Haanshuus, Christel Gill; Fevang, Børre; Aukrust, Pål; Langeland, Nina; Ueland, Thor (Peer reviewed; Journal article, 2018-12-18)BACKGROUND: The immune response during P. falciparum infection is a two-edged sword, involving dysregulation of the inflammatory responses with several types of immune cells participating. Here we examined T-cell, ... -
