Exploring Fatigue in Inflammatory Bowel Disease Patients
Abstract
Fatigue is a common phenomenon in IBD patients, which contributes significantly to the burden of the disease. The pathophysiology of IBD-related fatigue is considered multifactorial, but at present the underlying mechanisms are largely unknown. Based on the literature and the data presented in this thesis, we propose a multifactorial conceptual model in which both somatic and psychological factors are accounted for fatigue
Fatigue in patients with inflammatory bowel disease is associated with distinct differences in immune parameters
Background: Although it is well recognized that fatigue is an important problem in many of the quiescent inflammatory bowel disease (IBD) patients, it is unknown whether the immune status is different in fatigued versus non-fatigued patients. In this study, we contrasted various characteristics of the immune system in fatigued against non-fatigued patients with IBD in clinical remission. Patients and methods: Patients with IBD in clinical remission were phenotyped according to the Montreal classification, and the checklist individual strength-fatigue (CIS-fatigue) was used to assess fatigue (CIS-fatigue ≥ 35). Flow cytometry on peripheral blood samples was used to investigate differences in leukocyte subsets. The expression of various cytokines was determined in stimulated whole blood and serum samples using enzyme-linked immunosorbent assay. Differences between fatigued and non-fatigued patients with IBD were assessed. Results: In total, 55 patients were included in the fatigue group (FG) and 29 patients in the non-fatigue group (NFG). No differences in demographic and clinical characteristics were observed between the groups. Flow cytometry data showed a significantly lower percentage of monocytes (p = 0.011) and a higher percentage of memory T-cells (p = 0.005) and neutrophils (p = 0.033) in the FG compared with the NFG. Whole blood stimulation showed increased TNF-α (p = 0.022) and IFN-γ (p = 0.047) in the FG. The median serum level was significantly higher for IL-12 (p < 0.001) and IL-10 (p = 0.005) and lower for IL-6 (p = 0.002) in the FG compared with NFG. Conclusion: Significant differences in immune profile between fatigued and non-fatigued patients with IBD in clinical remission wer
Suppression of airway inflammation by Illicium verum and trans-anethole
_Background_
SH2 domain containing inositol-5-phosphatase (SHIP1) is an important modulator of innate
and adaptive immunity. In mice, loss of SHIP1 provokes severe ileitis resembling Crohn's
disease (CD), as a result of deregulated immune responses, altered cytokine production
and intestinal fibrosis. Recently, SHIP1 activity was shown to be correlated to the presence
of a CD-associated single nucleotide polymorphism in ATG16L1. Here, we studied SHIP1
activity and expression in an adult cohort of CD patients.
_Methods_
SHIP1 activity, protein and mRNA expression in peripheral blood mononuclear cells from
CD patients in clinical remission were determined by Malachite green assay, Western blotting

Sex-dimorphic adverse drug reactions to immune suppressive agents in inflammatory bowel disease
AIM: To analyze sex differences in adverse drug reactions (ADR) to the immune suppressive medication in inflammatory bowel disease (IBD) patients. METHODS: All IBD patients attending the IBD outpatient clinic of a referral hospital were identifed through the electronic diagnosis registration system. The electronic medical records of IBD patients were reviewed and the files of those patients who have used immune suppressive therapy for IBD, i.e., thiopurines, methotrexate, cyclosporine, tacrolimus and anti-tumor necrosis factor agents (anti-TNF); infiximab (IFX), adalimumab (ADA) and/or certolizumab, were further analyzed. The reported ADR to immune suppressive drugs were noted. The general definition of ADR used in clinical practice comprised the occurrence of the ADR in the temporal relationship with its disappearance upon discontinuation of the medication. Patients for whom the required information on drug use and ADR was not available in the electronic medical record and patients with only one registered contact and no further followup at the outpatient clinic were excluded. The difference in the incidence and type of ADR between male and female IBD patients were analyzed statistically by χ2 test. RESULTS: In total, 1009 IBD patients were identifed in the electronic diagnosis registration syst
Anemia and Iron Deficiency in Outpatients with Inflammatory Bowel Disease: Ubiquitous Yet Suboptimally Managed
Background: Iron deficiency (ID) and anemia in patients with Inflammatory Bowel Disease (IBD) are associated with a reduced quality of life. We assessed the prevalence of ID and anemia in Dutch outpatients with IBD and compared routine ID(A) management among medical professionals to the European Crohn’s and Colitis Organisation (ECCO) treatment guidelines. Methods: Between January and November 2021, consecutive adult outpatients with IBD were included in this study across 16 Dutch hospitals. Clinical and biochemical data were extracted from medical records. Additionally, medical professionals filled out questionnaires regarding routine ID(A) management. Results: In total, 2197 patients (1271 Crohn’s Disease, 849 Ulcerative Colitis, and 77 IBD-unclassified) were included. Iron parameters were available in 59.3% of cases. The overall prevalence of anemia, ID, and IDA was: 18.0%, 43.4%, and 12.2%, respectively. The prevalence of all three conditions did not differ between IBD subtypes. ID(A) was observed more frequently in patients with biochemically active IBD than in quiescent IBD (ID: 70.8% versus 23.9%; p < 0.001). Contrary to the guidelines, most respondents prescribed standard doses of intravenous or oral iron regardless of biochemical parameters or inflammation. Lastly, 25% of respondents reported not treating non-anemic ID. Conclusions: One in five patients with IBD suffers from anemia that—despite inconsistently measured iron parameters—is primarily caused by ID. Most medical professionals treat IDA with oral iron or standard doses of intravenous iron regardless of biochemical inflammation; however, non-anemic ID is often overlooked. Raising awareness about the management of ID(A) is needed to optimize and personalize routine care
