Abstract [en]

Background: Patients with ulcerative colitis often report fatigue. Objectives: To investigate prevalence of and risk factors for fatigue in patients with ulcerative colitis with active disease and during deep remission. Methods: In this cross-sectional study, disease activity was evaluated with endoscopy and calprotectin, and patients were classified as having active disease (n=133) or being in deep remission (n=155). Blood samples were analysed to assess anaemia, iron deficiency and systemic immune activity. Patients completed questionnaires to assess fatigue, psychological distress, gastrointestinal symptoms and quality of life. Results: The prevalence of high fatigue (general fatigue >= 13, Multidimensional Fatigue Inventory) was 40% in the full study population. Among patients with high fatigue, female gender and iron deficiency were more prevalent, and these patients had more severe disease activity and reported higher levels of anxiety, depression and decreased quality of life compared with patients with no/mild fatigue. A logistic regression analysis identified probable psychiatric disorder (odds ratio (OR) (confidence interval) 6.1 (3.1-12.2)), iron deficiency (OR 2.5 (1.2-5.1)), active disease (OR 2.2 (1.2-3.9)) and female gender (OR 2.1 (1.1-3.7)) as independent risk factors for high fatigue. Similar results were found concerning psychological distress, gender and quality of life, but immune markers did not differ in patients in deep remission with high vs. no/mild fatigue. Conclusions: Probable psychiatric disorder, iron deficiency, active disease and female gender are independent risk factors for high fatigue in patients with ulcerative colitis. Low-grade immune activity does not seem to be the cause of fatigue among patients in deep remission.
