The changing spectrum of microbial aetiology of respiratory tract infections in hospitalized patients before and during the COVID-19 pandemic
Serigstad, Sondre; Markussen, Dagfinn Lunde; Ritz, Christian; Ebbesen, Marit Helen; Knoop, Siri Tandberg; Kommedal, Øyvind; Heggelund, Lars; Ulvestad, Elling; Bjørneklett, Rune Oskar; Grewal, Harleen (Journal article; Peer reviewed, 2022-09-30)Background: The COVID-19 pandemic was met with strict containment measures. We hypothesized that societal infection control measures would impact the number of hospital admissions for respiratory tract infections, as well ... -
Diagnostic utility of oropharyngeal swabs as an alternative to lower respiratory tract samples for PCR-based syndromic testing in patients with community-acquired pneumonia
Serigstad, Sondre; Knoop, Siri Tandberg; Markussen, Dagfinn Lunde; Ulvestad, Elling; Bjørneklett, Rune Oskar; Ebbesen, Marit Helen; Kommedal, Øyvind; Grewal, Harleen (Journal article; Peer reviewed, 2023)Syndromic PCR-based analysis of lower respiratory tract (LRT) samples in patients with community-acquired pneumonia (CAP) improves the bacterial yield and time-to-results compared to culture-based methods. However, obtaining ... -
Humoral response to Epstein-Barr virus in patients with multiple sclerosis treated with B cell depletion therapy
Rød, Brit Ellen; Wergeland, Stig; Bjørnevik, Kjetil Lauvland; Holmøy, Trygve; Ulvestad, Elling; Njølstad, Gro; Myhr, Kjell-Morten; Torkildsen, Øivind (Journal article; Peer reviewed, 2023)Background B cell depletion therapy is highly effective in relapsing-remitting multiple sclerosis (RRMS). However, the precise underlying mechanisms of action for its biological effects in MS have still not been clarified. ... -
In vitro-stimulated IL-6 monocyte secretion and in vivo peripheral blood T lymphocyte activation uniquely predicted 15-year survival in patients with head and neck squamous cell carcinoma
Aarstad, Helene Hersvik; Vintermyr, Olav Karsten; Ulvestad, Elling; Kross, Kenneth Wilfried; Heimdal, John-Helge; Aarstad, Hans Jørgen (Peer reviewed; Journal article, 2015-06-16)The study was performed in order to determine whether peripheral blood monocyte in vitro function, and lymphocyte in vivo activation at diagnosis, was associated with HPV tumor infection status and 15-year survival in head ... -
Rapid syndromic PCR testing in patients with respiratory tract infections reduces time to results and improves microbial yield
Serigstad, Sondre; Grewal, Harleen; Ebbesen, Marit Helen; Kommedal, Øyvind; Heggelund, Lars; van Werkhoven, Werkhoven; Faurholt-Jepsen, Daniel; Clark, T.W.; Ritz, Christian; Ulvestad, Elling; Bjørneklett, Rune Oskar; Knoop, Siri Tandberg; Ravn, P.; Markussen, Dagfinn Lunde (Journal article; Peer reviewed, 2022)Lack of rapid and comprehensive microbiological diagnosis in patients with community acquired pneumonia (CAP) hampers appropriate antimicrobial therapy. This study evaluates the real-world performance of the BioFire FilmArray ... -
Seroprevalence of SARS-CoV-2 antibodies in a prospective cohort of patients admitted to an acute psychiatric ward in Norway during the initial months of the COVID-19 pandemic
Kroken, Rune Andreas; Stabell, Lena Antonsen; Grewal, Harleen; Ulvestad, Elling; Landsnes, Andreas Johan; Johnsen, Erik (Journal article; Peer reviewed, 2023)Background The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes coronavirus disease 2019 (COVID-19) spread around the world during the first part of 2020. The purpose of the study was to assess ...
