Fatigue in Inflammatory Bowel Disease Reflects Mood and Symptom-Reporting Behavior Rather Than Biochemical Activity or Anemia

Disease Acceptance, but not Perceived Control, is Uniquely Associated with Inflammatory Bowel Disease-related Disability

BACKGROUND AND AIMS

Disability, an important aspect of disease burden in patients with inflammatory bowel disease [IBD], has been suggested as a valuable clinical endpoint. We aimed to investigate how disease acceptance and perceived control, two psychological predictors of subjective health, are associated with IBD-related disability.

METHODS

In this cross-sectional study, adult IBD patients from the University Hospitals Leuven received a survey with questions about clinical and demographic characteristics, disease acceptance and perceived control [Subjective Health Experience model questionnaire], and IBD-related disability [IBD Disk]. Multiple linear regressions assessed predictors of IBD-related disability in the total sample and in the subgroups of patients in clinical remission or with active disease.

RESULTS

In the total sample (N = 1250, 54.2% female, median [interquartile range: IQR] age 51 [39-61] years, 61.3% Crohn's disease, 34.9% active disease), adding the psychological predictors to the model resulted in an increased explained variance in IBD-related disability of 19% compared with a model with only demographic and clinical characteristics [R2adj 38% vs 19%, p <0.001]. The increase in explained variance was higher for patients in clinical remission [ΔR2adj 20%, p <0.001] compared with patients with active disease [ΔR2adj 10%, p <0.001]. Of these predictors, disease acceptance was most strongly associated with disability in the total sample [β = -0.44, p <0.001], as well as in both subgroups [β = -0.47, p <0.001 and β = -0.31, p <0.001 respectively]. Perceived control was not significantly associated with disability when accounting for all other predictors.

CONCLUSIONS

Disease acceptance is strongly associated with IBD-related disability, supporting further research into disease acceptance as a treatment target.

Trajectories of health-related quality of life and fatigue during vedolizumab therapy in inflammatory bowel disease

BACKGROUND AND AIM

Normalizing health-related quality of life (QoL) and fatigue are important long-term treatment targets in inflammatory bowel disease (IBD). We examined their evolution in relation to changes in disease activity during vedolizumab therapy.

METHODS

Cohort study of biologically refractory IBD patients treated with vedolizumab. Patients were prospectively evaluated at all infusions by Short Health Scale (SHS) (QoL questionnaire covering four health dimensions) (n = 79), visual analogous scale for fatigue (VAS-F) (n = 30), and clinical disease activity. Objective disease assessment was carried out after 1 year or at treatment failure.

RESULTS

Patients in steroid-free clinical remission at end of induction improved significantly in all SHS items already from week 2 with full implementation by week 14 ("Symptoms" 59% improvement, P < 0.001; "Function" 63%, P < 0.001; "Worries" 59%, P < 0.001; "Well-being" 40%, P < 0.01). Then, SHS remained stable at background levels (< 20) for 1 year (improvements 67%; 65%; 62%; 57%; P < 0.001). Combined clinical-objective remission at 1 year was associated with highest SHS improvements (64-72%; P < 0.001). Of note, early SHS improvements preceded manifestation of clinical remission in most patients (22 of 33; 67%). Clinical response materialized into late (week 6 or later) and minor SHS improvements (31-46%, P < 0.001). Fatigue improved steadily over 6 months to background levels (VAS-F < 4) among patients in clinical remission (45% decrease) or clinical-objective remission (41%). SHS and VAS-F impairment remained elevated in patients without effect of therapy.

CONCLUSION

QoL rapidly improves and predicts later significant clinical-objective efficacies of vedolizumab at end of induction and 1 year. Fatigue improves slowly after remission is attained.

The relationship between Central Nervous System morphometry changes and key symptoms in Crohn’s disease

Alterations in grey matter volume (GMV) and cortical thickness (CT) in Crohn’s disease (CD) patients has been previously documented. However, the findings are inconsistent, and not a true representation of CD burden, as only CD patients in remission have been studied thus far. We investigate alterations in brain morphometry in patients with active CD and those in remission, and study relationships between brain structure and key symptoms of fatigue, abdominal pain, and extraintestinal manifestations (EIM). Magnetic Resonance Imaging brain scans were collected in 89 participants; 34 CD participants with active disease, 13 CD participants in remission and 42 healthy controls (HCs); Voxel based morphometry (VBM) assessed GMV and white matter volume (WMV), and surface-based analysis assessed cortical thickness (CT). We show a significant reduction in global cerebrospinal fluid (CSF) volume in CD participants compared with HCs, as well as, a reduction in regional GMV, WMV and CT in the left precentral gyrus (motor cortex), and an increase in GMV in the frontal brain regions in CD compared with HCs. Atrophy of the supplementary motor area (SMA) was associated with greater fatigue in CD. We also show alterations in brain structure in multiple regions in CD associated with abdominal pain and extraintestinal inflammations (EIMs). These brain structural alterations likely reflect neuroplasticity to a chronic systemic inflammatory response, abdominal pain, EIMs and fatigue. These findings will aid our understanding of the cross-linking between chronic inflammation, brain structural changes and key unexplained CD symptomatology like fatigue.

Fatigue is a systemic extraintestinal disease manifestation largely independent of disease activity, chronicity, and nutritional deficiencies in inflammatory bowel disease on biologics

BACKGROUND

Fatigue is a common symptom reported by patients with chronic immunoinflammatory diseases and with profound negative implications on health-related quality of life. This study aimed to delineate underlying components contributing to fatigue in patients with inflammatory bowel disease (IBD) receiving biologic therapy.

METHODS

Cross-sectional questionnaire study of all patients with IBD receiving any biologic therapy at a tertiary IBD center. Fatigue was assessed by Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F). Disease activity and quality of life were evaluated by generic questionnaires. Principal component analysis (PCA) was used to identify components of variables explaining fatigue.

RESULTS

Three hundred patients with IBD were included. Moderate-to-severe fatigue defined as FACIT-F ≤ 39 was present in half of the included patients. PCA condensed variables associated with fatigue into three main components contributing to 49% of observed fatigue. The first component, explaining 21% of fatigue, included factors related to disease chronicity, e.g., long disease duration, high number of previously used biologic therapies, presence of previous intestinal surgery, and increasing age. The second component explained 14% of fatigue and comprised disease activity-related aspects, e.g., disease activity indices and C-reactive protein. The third explained 14% of fatigue and comprised various nutritional deficiencies.

CONCLUSION

Fatigue can partly be explained by chronicity, disease activity, and nutritional deficits. However, the cause of fatigue is unexplained in approximately half of the patients with IBD supporting that fatigue can be an independent, systemic extraintestinal disease manifestation in IBD.

Prevalence and factors associated with fatigue in patients with ulcerative colitis in China: a cross-sectional study

BACKGROUND

Fatigue is one of the most common symptoms reported by patients with ulcerative colitis (UC), while it has not been fully recognized and taken seriously in clinical practice. We aimed to investigate the prevalence of fatigue in patients with UC and identify the factors associated with fatigue and its severity in China.

METHODS

A cross-sectional study was conducted in Affiliated Hospital of Nanjing University of Chinese Medicine from May 2020 to February 2021. Demographic and clinical characteristics were collected. Fatigue was evaluated with the Fatigue Severity Scale and the Multidimensional Fatigue Inventory. The Hospital Anxiety and Depression Scale, the Pittsburgh Sleep Index Scale and the Malnutrition Universal Screening Tool were respectively used to evaluate the anxiety, depression, sleep disturbance and nutritional risk of patients with UC.

RESULTS

A total of 220 UC patients were enrolled in this study. The prevalence of fatigue in patients was 61.8%, of which in patients with disease activity was 68.2%, and in patients in remission was 40.0%. Univariate analysis indicated that the Montreal classification, disease activity, anemia, anxiety, depression, sleep disturbance and high nutritional risk were the factors associated with fatigue in Patients with UC. Multivariate logistic regression analysis showed that the Montreal classification (E3: E1, OR = 2.665, 95% CI = 1.134-6.216), disease activity (OR = 2.157, 95% CI = 1.055-4.410) and anxiety (OR = 2.867, 95% CI = 1.154-7.126) were related to an increased risk of fatigue. Disease activity (RC = 0.240, 95% CI = 0.193-0.674) and anxiety (RC = 0.181, 95% CI = 0.000-0.151) were associated with severity of fatigue.

CONCLUSIONS

This study demonstrated that the prevalence of fatigue among UC patients in China. The Montreal classification, disease activity and anxiety are associated with an increased risk of fatigue.

A Novel Digital Self-management Intervention for Symptoms of Fatigue, Pain, and Urgency in Inflammatory Bowel Disease: Describing the Process of Development

Background

Empirical studies and systematic reviews have demonstrated the role of biological, cognitive, behavioral, and emotional factors in fatigue, pain, and urgency in inflammatory bowel disease (IBD). Behavioral management that addresses the cognitive, behavioral, and emotional factors offered alongside medical treatment is seldom available to people with IBD. Digital interventions provide a potentially scalable and cost-effective way of providing behavioral support to patients.

Objective

This paper aimed to describe the process of developing a supported digital self-management intervention for fatigue, pain, and urgency in IBD using theory and evidence-based approaches and stakeholder input.

Methods

The Medical Research Council framework for complex health interventions and a person-based approach were used to guide intervention development, consulting with 87 patients with IBD and 60 nurses. These frameworks informed the selection and use of a theoretical model that subsequently guided cognitive behaviorally based intervention content. They also guided the design of tailored digital intervention pathways for individuals with IBD that matched the predominant symptoms.

Results

A transsymptomatic cognitive behavioral framework of symptom perpetuation was developed for the symptoms of fatigue, pain, and urgency in IBD. A logic model was used to define the intervention techniques. Patient feedback and qualitative interviews refined the website content and functionalities, including the use of visual aids, email reminders, and graphical tracking of symptoms. Nurse focus groups informed the volume and delivery model of the therapist facilitator support. Ratings of acceptability out of 10 following feasibility testing (31/87, 36%) demonstrated accessibility (scoring 9.43, SD 1.040), ease (scoring 8.07, SD 3.205), clarity, and the relevant tone of the intervention. The final intervention comprised 12 web-based sessions (8 core and 4 symptom-specific), with one 30-minute facilitator phone call following session 1 and subsequent on-site messaging.

Conclusions

The use of theory and integration of stakeholders’ views throughout informed the development of an evidence-based digital intervention for fatigue, pain, and urgency in IBD. This is the first web-based self-management intervention designed to address these multiple symptoms with the aim of improving the quality of life and reducing the symptom burden of IBD. The intervention is being tested in a large multicenter randomized controlled trial.

Inflammatory Bowel Disease-related Behaviours [IBD-Bx] Questionnaire: Development, Validation and Prospective Associations with Fatigue

BACKGROUND AND AIMS

Disease-related behaviours that may maintain or worsen symptom burden remain largely unexplored in inflammatory bowel disease [IBD]. In this study, we developed and validated an instrument assessing IBD-related, modifiable behaviours and explored which behaviours prospectively correlate with fatigue, a debilitating and common symptom in IBD.

METHODS

Initially, 72 items reflecting IBD-related behaviours were generated based on literature review and input from clinicians and people diagnosed with IBD. During wave 1, 495 IBD patients rated to what extent each behaviour was applicable to them. Additionally, disease activity, fatigue, IBD-related concerns and psychological variables were assessed. During a follow-up visit 4-12 weeks later [wave 2], a random selection of 92 patients from wave 1 completed the measures assessing the IBD-related behaviours, disease activity and fatigue once more.

RESULTS

A principal component analysis with oblique rotation revealed seven components in the 72 IBD behaviours, which could be interpreted as: [1] Avoiding food and activities, [2] Access to toilets, [3] Avoidance of sex, [4] Cognitive avoidance, [5] Not sharing with others, [6] Alternative treatments and [7] Disease management. Each component was reduced to three to five representative items, resulting in a final, 25-item IBD-Bx questionnaire showing good concurrent validity [alphas > 0.63] and reliability. Almost all components were cross-sectionally related to levels of fatigue. Avoiding food and activities and Access to toilets significantly predicted fatigue at wave 2 when controlling for baseline fatigue.

CONCLUSIONS

The IBD-Bx is a valid and reliable questionnaire of IBD-related behaviours, some of which predict future fatigue burden.

Influencing Factors of Inflammatory Bowel Disease-Fatigue: A Path Analysis Model

BACKGROUND

Fatigue is a common symptom in adults with inflammatory bowel disease (IBD) and is influenced by many physiological, psychological, and situational factors. However, the influencing factors of fatigue associated with IBD have not been evaluated.

OBJECTIVE

This study aims to examine factors associated with fatigue during IBD and develop a parsimonious model that describes the influencing factors of fatigue.

METHODS

The study was a secondary analysis of cross-sectional data obtained from IBD Partners, an online cohort of adults with the disease, including 12,053 eligible participants. Data were collected using the Patient-Reported Outcomes Measurement Information System short-form scales measuring fatigue, sleep disturbances, pain interference, anxiety, depression, and satisfaction with social roles. Physical activity was measured using a single question. Demographic and clinical variables were collected. Path analysis was computed to identify the direct and indirect effects of situational, physiological, and psychological factors on IBD-fatigue based on the middle range theory of unpleasant symptoms' conceptual framework.

RESULTS

Most of the participants were White females. The data best fit a model with situational factors (physical activity and satisfaction with social roles as the mediators). The direct effect of IBD activity, age, sleep disturbances, pain interference, anxiety, and depression on IBD-fatigue was significant. Significant indirect effects were noted on IBD-fatigue from sleep disturbances, pain interference, and depression via physical activity and satisfaction with social roles.

DISCUSSION

The study identified two important intervening variables from the tested model. In addition, other symptoms such as sleep, pain, anxiety, and depression are essential and also influence IBD-fatigue.

Sarcopenia, severe anxiety and increased C-reactive protein are associated with severe fatigue in patients with inflammatory bowel diseases

Patients with inflammatory bowel disease (IBD) report fatigue more frequently than healthy population, but the precise mechanisms underlying its presence are unknown. This study aimed to evaluate the prevalence of fatigue in IBD and its relation with potential causative factors. A survey on fatigue, depression, anxiety, sleep disorders, and the presence of sarcopenia and malnutrition, was sent by email to 244 IBD outpatients of the Gastroenterology Unit of Academic Hospital of Padua. Demographics and clinical data, including the levels of fecal calprotectin (FC) and C-reactive protein (CRP), and current pharmacological treatments were obtained from patients' medical records. Ninety-nine (40.5%) subjects answered the survey. Ninety-two (92.9%) patients reported fatigue, with sixty-six having mild to moderate fatigue and twenty-six severe fatigue. Multivariate analysis showed that abnormal values of CRP (OR 5.1), severe anxiety (OR 3.7) and sarcopenia (OR 4.4) were the factors independently associated with severe fatigue. Fatigue has a high prevalence in subject affected by IBD. Subjects with altered CRP, sarcopenia and severe anxiety appear more at risk of severe fatigue.

The Gut-Brain Axis and Its Role in Controlling Eating Behavior in Intestinal Inflammation

Malnutrition represents a major problem in the clinical management of the inflammatory bowel disease (IBD). Presently, our understanding of the cross-link between eating behavior and intestinal inflammation is still in its infancy. Crohn's disease patients with active disease exhibit strong hedonic desires for food and emotional eating patterns possibly to ameliorate feelings of low mood, anxiety, and depression. Impulsivity traits seen in IBD patients may predispose them to palatable food intake as an immediate reward rather than concerns for future health. The upregulation of enteroendocrine cells (EEC) peptide response to food intake has been described in ileal inflammation, which may lead to alterations in gut-brain signaling with implications for appetite and eating behavior. In summary, a complex interplay of gut peptides, psychological, cognitive factors, disease-related symptoms, and inflammatory burden may ultimately govern eating behavior in intestinal inflammation.

Cognitive-behavioural therapy for the management of inflammatory bowel disease-fatigue: a feasibility randomised controlled trial

Background

Fatigue is the third most prevalent symptom for patients with inflammatory bowel disease (IBD), yet optimal strategies for its management are unclear. Treatment protocols for fatigue in other conditions have been based on cognitive-behavioural models. Targeting cognitions, emotions and behaviour related to fatigue through cognitive-behavioural therapy (CBT) may be a viable option to improve fatigue and quality of life (QoL) in IBD.

Methods

This single centre, two-arm, feasibility randomised controlled trial (RCT) aimed to assess the feasibility and initial estimates of potential efficacy of a CBT intervention for the management of IBD-fatigue. Feasibility, acceptability and initial estimates of potential efficacy outcomes were collected through self-report measures and semi-structured interviews. Participants were recruited from one tertiary referral centre. Intervention Group 1 received a CBT manual for fatigue, one 60-min and seven 30-min telephone sessions with a therapist over 8-weeks. Control Group 2 received a fatigue information sheet without therapist support. A nested qualitative study evaluated patients’ and therapists’ experiences, and IBD-healthcare professionals’ (HCPs) perceptions of the intervention.

Results

Eighty-nine participants were assessed for eligibility. Of these, 31 of the 70 eligible participants consented to participate (recruitment rate of 44%). Of the 15 participants randomised to the intervention group, 13 (87%) started it and 10 (77% of those who started) completed all 8 sessions. Follow-up questionnaires were completed by 22 (71%) participants at 3 months, 14 (45%) at 6 months and 12 (39%) at 12 months’ follow-up. The intervention was acceptable to participants and feasible for therapists to deliver. HCPs reported that the intervention would be applicable, but time, finance and training constraints limit its implementation. Initial estimates of potential efficacy with complete case analysis showed a reduction in fatigue and an increase in QoL at 3, 6 and 12 months post-randomisation.

Conclusions

A full-scale effectiveness RCT testing CBT for IBD-fatigue is feasible and is potentially worthwhile with some changes to the protocol. However, given the small numbers, further pilot work is warranted before a full-scale RCT.

Randomized controlled trial: a pilot study of a psychoeducational intervention for fatigue in patients with quiescent inflammatory bowel disease

Introduction:

Fatigue is a frequent, debilitating symptom of inflammatory bowel disease (IBD). Despite this, studies report dissatisfaction among IBD patients regarding how little attention is given to fatigue-related issues during consultations. We performed a pilot randomized controlled trial (RCT) to assess whether a brief, structured, multidisciplinary psychological support program improved fatigue, mood and quality of life indices in patients with quiescent IBD.

Methods:

The intervention consisted of three small-group psychoeducational sessions over 6 months. Primary outcomes were effect on fatigue severity and impact scores. Secondary outcomes included effect on depression, anxiety, somatization scores, generic and disease-specific quality of life.

Results:

Twenty-three patients were enrolled, 10 in the intervention arm and 13 controls. Mean fatigue severity and impact scores improved for patients in the intervention group (by 14.5–13.1 and 49.7–45.8, respectively), and worsened in controls (by 11.5–12.6 and 33.5–35 respectively). Mean Short Form 36 (SF-36) scores for role limitations due to physical health decreased from 44.4 to 38.9 in the intervention group, but increased from 44.2 to 51.9 among controls. Energy scores in the intervention group improved from 17.8 to 26.6, but only from 31.4 to 31.7 among controls. Short IBD questionnaire scores improved in both groups, from 46.2 to 45.2 in controls compared with 44.4–40 in the intervention group.

Discussion:

In this small pilot RCT, positive effects were demonstrated on fatigue, energy levels and other quality of life outcomes. Larger, adequately powered studies with longer follow up are required.

Fatigue and its associated factors in microscopic colitis

BACKGROUND

Fatigue is a well-recognized symptom in patients with inflammatory bowel disease and irritable bowel syndrome (IBS), and has been associated with psychological comorbidity and impaired quality of life in both. However, features associated with fatigue in patients with microscopic colitis (MC) are less clear.

MATERIALS AND METHODS

We conducted a cross-sectional survey of patients with a new diagnosis of MC including levels of anxiety, depression, somatization, quality of life, and IBS-type symptoms. Levels and impact of fatigue were assessed using the Inflammatory Bowel Disease Fatigue self-assessment scale. Mean scores were compared against various patient characteristics, and were also correlated with anxiety, depression, somatization, and quality-of-life scores.

RESULTS

In total, 129 patients with MC diagnosed between 2010 and 2015 returned completed postal questionnaires. Common histological subtypes were collagenous colitis (53.5%, n = 69) and lymphocytic colitis (38.8%, n = 50). Higher mean fatigue severity and impact scores were associated with the presence of irritable-bowel-syndrome-type symptoms, abnormal levels of anxiety and depression, and high levels of somatization (p < 0.0001 for all), but those reporting ongoing symptoms attributable to MC did not report significantly higher scores. There were significant positive correlations between total anxiety, depression, or somatization scores and fatigue severity and impact scores, and significant negative correlations with quality-of-life measures (p < 0.001 for all).

CONCLUSIONS

Fatigue in MC appears to be associated with reporting IBS-type symptoms, psychological comorbidity and impaired quality of life. It may therefore represent an important target for treatment.
