Introduction:
Fatigue is an extraintestinal manifestation in patients with inflammatory bowel disease (IBD), such as Crohn's disease (CD) and ulcerative colitis (UC), with limited information on the underlying factors. This study aimed to determine the prevalence of fatigue and associated factors in IBD patients.
Methods:
This prospective observational study assessed 216 IBD patients treated with intravenous infliximab or vedolizumab. Clinically meaningful fatigue was defined using a visual analog scale with a score ≥4 (VAS-F, range 0-10). Further assessments included the patient health questionnaire (PHQ-8) for depressive symptoms, the IBD-control-8 questionnaire to evaluate subjective disease control and the fatigue impact scale (FIS) for patients' quality of life (QoL). Demographic, clinical and laboratory data of the study population were collected and compared to identify fatigue-associated factors.
Results:
Overall, 53.2% (n = 115) of the IBD patients reported clinically meaningful fatigue with a higher prevalence in UC (63.0%) versus CD (47.4%). Among patients with CD, disease activity was significantly associated with fatigue symptoms (p < 0.001), whereas no such correlation was observed in UC patients (p = 0.85). Clinically meaningful fatigue symptoms were reported in 90.9% of patients with depressive symptoms (PHQ-8 ≥10). Furthermore, patients with fatigue were younger (40 vs. 42 years, p = 0.04), reported more frequent use of concomitant psychoactive and/or sedative medication (p = 0.03) and had lower IBD-control-8 scores (median 12 vs. 16 points, p < 0.001). Only minor differences were observed when comparing serum and fecal laboratory values of patients with fatigue symptoms to those without.
Conclusion:
Fatigue is highly prevalent among IBD patients treated with vedolizumab or infliximab and has a substantial impact on patients' QoL. Fatigue and depressive symptoms were strongly associated, suggesting closer monitoring for depression and the use of psychoactive medication in patients with IBD.

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
