      Background & Aims To influence host and disease phenotype, compositional microbiome changes, which have been demonstrated in patients with primary sclerosing cholangitis (PSC), must be accompanied by functional changes. ...
    • Gut microbiota-dependent trimethylamine N-oxide associates with inflammation in common variable immunodeficiency 

      Macpherson, Magnhild Eide; Hov, Johannes Espolin Roksund; Ueland, Thor; Dahl, Tuva Børresdatter; Kummen, Martin; Otterdal, Kari; Holm, Kristian; Berge, Rolf Kristian; Mollnes, Tom Eirik; Trøseid, Marius; Halvorsen, Bente; Aukrust, Pål; Fevang, Børre; Jørgensen, Silje Fjellgård (Journal article; Peer reviewed, 2020)
      A substantial proportion of patients with common variable immunodeficiency (CVID) have inflammatory and autoimmune complications of unknown etiology. We have previously shown that systemic inflammation in CVID correlates ...
    • Impact of HIV and type 2 diabetes on gut microbiota diversity, tryptophan catabolism and endothelial dysfunction 

      Hoel, Hedda Benedicte; Hove-Skovsgaard, Malene; Hov, Johannes Espolin Roksund; Gaardbo, Julie Christine; Holm, Kristian; Kummen, Martin; Rudi, Knut; Nwosu, Felix; Valeur, Jørgen; Gelpi, Marco; Seljeflot, Ingebjørg; Ueland, Per Magne; Gerstoft, Jan; Ullum, Henrik; Aukrust, Pål; Nielsen, Susanne Dam; Trøseid, Marius (Peer reviewed; Journal article, 2018-04-30)
      HIV infection and type 2 diabetes are associated with altered gut microbiota, chronic inflammation, and increased cardiovascular risk. We aimed to investigate the combined effect of these diseases on gut microbiota composition ...
    • Low fibre intake is associated with gut microbiota alterations in chronic heart failure 

      Mayerhofer, Cristiane C.K.; Kummen, Martin; Holm, Kristian; Broch, Kaspar; Awoyemi, Ayodeji Olawale; Vestad, Beate; Larsen, Christopher Storm; Seljeflot, Ingebjørg; Ueland, Thor; Bohov, Pavol; Berge, Rolf Kristian; Svardal, Asbjørn M.; Gullestad, Lars; Yndestad, Arne; Aukrust, Pål; Hov, Johannes Espolin Roksund; Trøseid, Marius (Journal article; Peer reviewed, 2020)
      Aims Recent reports have suggested that patients with heart failure (HF) have an altered gut microbiota composition; however, associations with diet remain largely uninvestigated. We aimed to explore differences in the ...
    • 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 ...
    • Rifaximin or Saccharomyces boulardii in heart failure with reduced ejection fraction: Results from the randomized GutHeart trial 

      Awoyemi, Ayodeji Olawale; Mayerhofer, Cristiane; Felix, Alex S.; Hov, Johannes Espolin Roksund; Moscavitch, Samuel D.; Lappegård, Knut Tore; Hovland, Anders; Halvorsen, Sigrun; Halvorsen, Bente; Gregersen, Ida; Svardal, Asbjørn M.; Berge, Rolf Kristian; Hansen, Simen Hyll; Götz, Alexandra; Holm, Kristian; Aukrust, Pål; Åkra, Sissel; Seljeflot, Ingebjørg; Solheim, Svein; Lorenzo, Andrea; Gullestad, Lars; Trøseid, Marius; Broch, Kaspar (Journal article; Peer reviewed, 2021)
      Background The gut microbiota represents a potential treatment target in heart failure (HF) through microbial metabolites such as trimethylamine N-oxide (TMAO) and systemic inflammation. Treatment with the probiotic yeast ...
    • Rosuvastatin alters the genetic composition of the human gut microbiome
