      Background Fatigue is common in patients with chronic inflammatory and autoimmune diseases, often with a severe impact on the patient’s daily life. From a biological point of view, fatigue can be regarded as an element ...
    • Interleukin-1-related activity and hypocretin-1 in cerebrospinal fluid contribute to fatigue in primary Sjögren's syndrome 

      Bårdsen, Kjetil; Brede, Cato; Kvivik, Ingeborg; Kvaløy, Jan Terje; Jonsdottir, Kristin; Tjensvoll, Anne Bolette; Ruoff, Peter; Omdal, Roald (Peer reviewed; Journal article, 2019)
      Background Fatigue is a common and sometimes debilitating phenomenon in primary Sjögren’s syndrome (pSS) and other chronic inflammatory diseases. We aimed to investigate how IL-1 β-related molecules and the neuropeptide ...
    • Interleukin-1β, heat shock protein 90α, and hypocretin-1 in chronic fatigue
