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 ... -
Comparison of rapid molecular testing methods for detecting respiratory viruses in emergency care: a prospective study
Markussen, Dagfinn Lunde; Grewal, Harleen; Knoop, Siri Tandberg; Serigstad, Sondre; Kommedal, Øyvind; Ebbesen, Marit Helen; Ulvestad, Elling; Bjørneklett, Rune Oskar (Journal article; Peer reviewed, 2022)Background Respiratory tract infections (RTIs) caused by contagious viruses are common among patients presenting to the emergency department (ED). Early detection of these viruses can help prevent nosocomial transmissio ... -
The diagnostic utility of microscopic quality assessment of sputum samples in the era of rapid syndromic PCR testing
Markussen, Dagfinn Lunde; Ebbesen, Marit Helen; Serigstad, Sondre; Knoop, Siri Tandberg; Ritz, Christian; Bjørneklett, Rune Oskar; Kommedal, Øyvind; Jenum, Synne; Ulvestad, Elling; Grewal, Harleen (Journal article; Peer reviewed, 2023)This prospective study assessed the value of initial microscopy evaluation of sputum samples submitted for rapid syndromic PCR-based testing. Bacterial detections by the BioFire FilmArray Pneumonia Panel plus in 126 high- ... -
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 ... -
Impact of rapid molecular testing on diagnosis, treatment and management of community-acquired pneumonia in Norway: a pragmatic randomised controlled trial (CAPNOR)
Serigstad, Sondre; Ritz, Christian; Faurholt-Jepsen, Daniel; Markussen, Dagfinn Lunde; Ebbesen, Marit Helen; Kommedal, Øyvind; Bjørneklett, Rune Oskar; Heggelund, Lars; Clark, Tristan W.; van Werkhoven, Cornelis H.; Knoop, Siri Tandberg; Ulvestad, Elling; Grewal, Harleen (Journal article; Peer reviewed, 2022)Background: Community-acquired pneumonia (CAP) causes a large burden of disease. Due to difficulties in obtaining representative respiratory samples and insensitive standard microbiological methods, the microbiological ... -
Protein and transcriptional biomarker profiling may inform treatment strategies in lower respiratory tract infections by indicating bacterial–viral differentiation
Sivakumaran, Dhanasekaran; Jenum, Synne; Markussen, Dagfinn Lunde; Serigstad, Sondre; Srivastava, Aashish; Saghaug, Christina Skår; Ulvestad, Elling; Knoop, Siri Tandberg; Grewal, Harleen (Journal article; Peer reviewed, 2024)Lower respiratory tract infections (LRTIs) remain a significant global cause of infectious disease-related mortality. Accurate discrimination between acute bacterial and viral LRTIs is crucial for optimal patient care, ... -
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 ... -
Syndromic molecular testing in adults hospitalized for suspected community-acquired pneumonia
Serigstad, Sondre (Doctoral thesis, 2023-10-26)Den mikrobielle etiologien hos pasienter med samfunnservervet lungebetennelse (CAP) blir ofte ikke avklart på grunn av utilstrekkelige mikrobiologiske metoder og vanskeligheter med å skaffe prøver fra nedre luftveier. Rask ...
