Assessing fatigue in inflammatory bowel disease: comparison of three fatigue scales

Top Ten Tips Palliative Care Clinicians Should Know About Diagnosing, Categorizing, and Addressing Fatigue

Fatigue is a multifactorial symptom that is commonly faced by patients with cancer, chronic disease, and other serious illnesses. Fatigue causes suffering across biopsychosocial domains and affects patients and their loved ones. In this article, a consortium of professionals across cancer care, physical therapy, exercise, pharmacy, psychiatry, and palliative medicine offers tips and insights on evaluating, categorizing, and addressing fatigue in the setting of serious illness. The comprehensive approach to managing fatigue underscores the importance of collaborative efforts characteristic of interdisciplinary palliative care. Prioritizing screening, diagnosing, and treating fatigue is crucial for enhancing patients' and families' overall quality of life.

Treatment Pathways in Patients With Crohn's Disease and Ulcerative Colitis: Understanding the Road to Advanced Therapy

Background

Patients with Crohn's disease (CD) or ulcerative colitis (UC) often cycle through conventional therapies (CT) with different mechanisms of action (MOA) before initiating advanced therapy (AT). We describe treatment patterns among patients with CD/UC.

Methods

Using Merative MarketScan Research databases, adult patients with CD/UC were identified from medical/pharmacy claims (2017-2021). Patients had ≥1 hospitalization or ≥2 outpatient visits (≥30 days apart within 1 year) for CD/UC. Two cohorts were established; cohort 1: Newly diagnosed patients (index date is the date of first diagnosis) and cohort 2: Patients initiating AT (index date is the date of first AT). First-line treatment patterns (cohort 1) and CT pathways before AT initiation (cohort 2) by the number of episodes (ie, adding a new therapy, switching to another therapy, or restarting the same therapy after ≥60 days) and MOA are reported.

Results

Among newly diagnosed patients in cohort 1 (CD: n = 1739; UC: n = 2740), 14.4% (CD) and 5.9% (UC) of patients had any AT use during the follow-up period (mean: 2.3 years; ≥ 77% initiated corticosteroids). Among patients in cohort 2 (CD: n = 2594; UC: n = 2431), the mean number of CT episodes before AT initiation was 4.0 ± 4.3 (CD) and 5.9 ± 5.0 (UC). Among those with ≥1 corticosteroid episode (CD: 82.2%; UC: 91.5%), the mean number of episodes was 4.6 ± 4.3 (CD) and 6.3 ± 5.0 (UC). Overall, 13.3% (CD) and 23.7% (UC) of patients cycled through 3 MOAs before AT initiation.

Conclusions

Despite treatment recommendations, few newly diagnosed CD/UC patients initiated AT as their first treatment. Moreover, patients cycled through multiple CTs before initiating AT.

Insights into disability and psycho-social care of patients with inflammatory bowel disease

In recent years, the concept of disability has increasingly garnered attention as a crucial long-term target of inflammatory bowel disease (IBD) management. The treatment paradigm has changed dramatically from full control of the disease (clinical and endoscopic remission) toward physical and emotional well-being with the goal of preventing disability and normalizing quality of life. However, in certain cases, despite achieving good disease control, patients may still experience symptoms associated with disability, and reduced emotional wellness. These symptoms can significantly impact various biopsychosocial factors, including interpersonal relationships, educational or work-related activities, body image, and sexual functioning. Nevertheless, they often remain overlooked in the context of IBD care. In this narrative review, we aim to shed light on the burden of certain disability-related symptoms such as bowel urgency, sexual dysfunction, impaired fertility and fatigue, emphasizing the importance of acknowledging and validating them in a clinical setting. There is a demanding need for comprehensive care for IBD patients, with IBD clinicians being mindful of the psychosocial challenges faced by their patients. Providing timely and appropriate management of these challenges alongside IBD treatment is key to achieving holistic remission and enhancing the overall quality of life while reducing disability.

Fatigue, Toll-Like Receptor 4, and Pro-Inflammatory Cytokines in Adults With Subarachnoid Hemorrhage: A 6-Month Longitudinal Study

BACKGROUND

Fatigue is prevalent in subarachnoid hemorrhage (SAH) survivors. Biological mechanisms underlying fatigue post-SAH are not clear. Inflammation may contribute to the development of fatigue. This study aimed to examine the associations between inflammatory markers and fatigue during the first 6 months post-SAH. Specific biomarkers examined included both early and concurrent expression of Toll-Like Receptor 4 (TLR4) messenger RNA (mRNA) and plasma concentrations of pro-inflammatory cytokines, Tumor Necrosis Factor-alpha (TNF-α), Interleukin (IL)1β, and IL6.

METHODS

We conducted a 6-month longitudinal study with a convenience sample of 43 SAH survivors. We collected blood samples on days 2, 3, and 7 and 2, 3, and 6 months post-SAH to assess biomarkers. Fatigue was assessed by the PROMIS Fatigue Scale at 2, 3, and 6 months. Linear mixed models were used to test the associations between early (days 2, 3, and 7) and concurrent (2, 3, and 6 months) TLR4 mRNA expression (TagMan gene expression assays) and TNF-α, IL1β, and IL6 plasma concentrations (multiplex assays) and concurrent fatigue.

RESULTS

28% of SAH survivors experienced fatigue during the first 6 months post-SAH. Fatigue levels in SAH survivors were higher than those of the U.S. population and consistent during the 6 months. Experience of fatigue during the 6 months post-SAH was associated with higher IL1β plasma concentrations on day 7 and IL1β, IL6, and TNF-α plasma concentrations during the 6 months post-SAH.

CONCLUSION

Inflammation appears to underlie the development of fatigue in SAH survivors.

Fatigue, sarcopenia, and frailty in older adults with inflammatory bowel disease

Inflammatory bowel diseases (IBDs) are characterized by a multifactorial clinical picture, in which age-related physical, functional and psychological symptoms may coexist. The accurate evaluation and identification of such symptomatology acquires considerable importance in the context of older adults, since those core factors typical of IBD may also expose older patients to an increased risk for age-related negative outcomes, such as frailty and disability. The purpose of the present review was to provide an updated overview on the evaluation and management of IBD in the elderly population, with regard to fatigue, sarcopenia, and frailty. The assessment of fatigue might contribute to the identification of early symptoms of IBD, such as pain and mood disorders, which should be treated timely to offer elderly patient a better quality of life. Similarly, an accurate evaluation of sarcopenia might represent a useful Prognostic Index to identify those patients at risk of developing physical frailty. Frailty in IBD should be evaluated not only in relation to the occurrence of negative outcomes, but also should be considered itself as an outcome itself in IBD. A recommendation for future research on this topic might be the implementation of randomized trials, which include older adults and evaluate fatigue, sarcopenia, and frailty. Similarly, the development of tailored intervention programs, based on both physical and psychological outcomes, with the purpose of improving patients' adaptation to the disease, and monitoring the evolution of symptoms and the response to therapies over time, should be encouraged.

Psychometric Performance of Fatigue Scales in Inflammatory Bowel Disease

BACKGROUND

Fatigue is highly prevalent in people with inflammatory bowel disease (IBD). Fatigue scales are important for studies testing fatigue interventions, but information about psychometric properties of many scales is insufficient in IBD. We compared the psychometric properties of multiple generic fatigue scales in participants with IBD.

METHODS

Individuals with IBD (N = 216) completed the Daily Fatigue Impact Scale (DFIS), the vitality subscale of the RAND-36, and the Patient Health Questionnaire-9 (PHQ-9) fatigue item twice. A subgroup (n = 84) also completed the Fatigue Impact Scale (FIS) once, from which we also scored the 21 items from the Modified Fatigue Impact Scale (MFIS-IBD). We assessed floor/ceiling effects, construct validity, and internal consistency reliability. Using relative efficiency (RE), we compared discriminating ability and comparative responsiveness of the measures regarding disease activity and employment status and changes.

RESULTS

The FIS, MFIS, and RAND-36-vitality scales did not exhibit floor or ceiling effects. The DFIS showed mild floor effects (19.4%), and the PHQ-9 fatigue item showed floor (18.1%) and ceiling (20.8%) effects. Internal consistency reliability exceeded 0.93 for FIS, MFIS-IBD, and DFIS and was 0.81 for the RAND-36-vitality scale. In the subgroup analysis, the FIS, MFIS-IBD, and DFIS were strongly correlated with each other (r ≥ 0.90). The ability to discriminate between disease activity groups was highest for the FIS and MFIS-IBD, followed by the DFIS. The FIS, MFIS-IBD, and DFIS were responsive to changes in work impairment.

CONCLUSIONS

The FIS, MFIS-IBDs and DFIS had adequate validity and reliability for assessing fatigue in IBD.

Translation, validation and psychometric properties of the Dutch version of the Inflammatory Bowel Disease-Fatigue (IBD-F) self-assessment scale

BACKGROUND

In patients with inflammatory bowel disease (IBD), a symptom with major impact on health-related quality of life is fatigue. To assess fatigue and conduct research regarding fatigue in IBD patients, a validated disease specific assessment tool is required. The aim of this study was to translate the Inflammatory Bowel Disease Fatigue patient self-assessment scale (IBD-F) into Dutch and to validate this translated scale in a Dutch IBD population.

METHODS

The study comprised three phases. In phase 1, the original IBD-F was translated into Dutch. Phase 2 comprised a pilot-test of the pre-final Dutch IBD-F to assess content validity by applying a semi-structured interview design. In phase 3, construct validity, internal consistency and test-retest reliability were assessed using a cross-sectional design.

RESULTS

Phase 1 resulted in the pre-final version of the Dutch IBD-F. After five semi-structured interviews with IBD patients in phase 2, minor adjustments were made which resulted in the final version of the Dutch IBD-F. Evaluation of this final version in 133 IBD patients showed adequate psychometric properties: good convergent validity with the Multidimensional Fatigue Inventory subscales (Spearman's r 0.57-0.86) and excellent internal consistency (Cronbach's alpha 0.94 for Section I and 0.97 for Section II). Test-retest reliability in 102 patients was shown to be good (Section I ICC 0.85 (95% CI 0.79-0.90) and Section II ICC 0.88 (95% CI 0.83-0.92)).

CONCLUSIONS

The thorough translation process resulted in a comprehensible, valid and reliable version of the Dutch IBD-F. Convergent validity with the MFI-20 appeared to be good. This study found excellent internal consistency and good test-retest reliability.

Economic Burden of Fatigue in Inflammatory Bowel Disease

Background

This retrospective study gathered medical/pharmacy claims data on patients with inflammatory bowel disease (IBD) between January 01, 2000 and March 31, 2019 from the IBM MarketScan commercial claims database to assess the real-world impact of fatigue on healthcare costs in patients newly diagnosed with IBD.

Methods

Eligible participants were ≥18 years, newly diagnosed with IBD (≥2 separate claims), and had ≥12 months of continuous database enrollment before and after fatigue diagnosis. The date of fatigue diagnosis was the index date; participants were followed for 12 months post-index. Patients with (cases) or without (controls) fatigue were matched 1:1 by propensity score matching. Patients with evidence of prior IBD diagnosis/treatment, or those with a chronic disease other than IBD wherein fatigue is the primary symptom, were excluded. Healthcare resource utilization (HCRU), including hospitalizations, inpatient and outpatient visits, and associated costs were compared between cases and controls.

Results

Matched IBD cohorts (21 321 cases/21 321 controls) were identified (42% Crohn's disease [CD] and 58% ulcerative colitis [UC]) with similar baseline characteristics (average age: 46 years; 60% female). Cases versus controls had significantly more all-cause outpatient visits (incidence rate ratio [IRR], 95% confidence intervals [95% CI]: 1.64 [1.61, 1.67], P < .001) and all-cause hospitalizations (IRR [95% CI]: 1.92 [1.81, 2.04], P < .001); as well as significantly higher all-cause total direct healthcare costs (mean: $24 620 vs. $15 324; P < .001). Similar findings were observed for IBD-related outcomes, as well as in CD- and UC-specific subgroups.

Conclusions

Presence of fatigue is associated with an increase in HCRU and total medical costs among patients newly diagnosed with IBD.

Fatigue Is Associated with Anxiety and Lower Health-Related Quality of Life in Patients with Inflammatory Bowel Disease in Remission

Background and Objectives: Inflammatory bowel diseases (IBD) are chronic conditions with an unpredictable course and a remitting–relapsing evolution. Fatigue is a frequent complaint in patients with IBD, affecting approximately half of the newly diagnosed patients with IBD. The aim of this study was to analyze fatigue in patients with IBD in remission. Materials and Methods: One hundred nineteen consecutive outpatients diagnosed with IBD for over 3 months that were in corticosteroid-free clinical and biochemical remission at the time of assessment were included in this cross-sectional study. Out of them, 72 (60.5%) were male; the median age was 39 years (IQR 30–47). Seventy-seven patients (64.7%) were diagnosed with Crohn’s disease and forty-two (35.3%) with ulcerative colitis, with a median disease duration of 6 years (IQR 2–10). Fatigue, health-related quality of life (HR-QoL), anxiety and depression were evaluated using the following self-administered questionnaires: FACIT Fatigue, IBDQ 32 and HADS. Results: The mean FACIT-Fatigue score was 41.6 (SD ± 8.62), and 38.7% of patients were revealed as experiencing fatigue when a cut-off value of 40 points was used. The mean IBDQ 32 score was 189.4 (SD ± 24.1). Symptoms of anxiety and depression were detected in 37% and 21% of the patients, respectively. In the multivariate analysis, fatigue was significantly associated with lower HR-QoL (OR 2.21, 95% CI: 1.42–3.44, p < 0.001), symptoms of anxiety (OR 5.04, 95% CI: 1.20–21.22, p = 0.008), female sex (OR 3.32, 95% CI: 1.02–10.76, p = 0.04) and longer disease duration (OR 1.13, 95% CI: 1.01–1.27, p = 0.04). Conclusions: Fatigue is highly prevalent even in patients with inactive IBD and is correlated with lower HR-QoL and anxiety, as well as with clinical factors such as longer disease duration and female sex.

Chronic Fatigue Syndrome in Patients with Deteriorated Iron Metabolism

Fatigue is a common, non-specific symptom that often impairs patients’ quality of life. Even though fatigue may be the first symptom of many serious diseases, it is often underestimated due to its non-specific nature. Iron metabolism disorders are a prominent example of conditions where fatigue is a leading symptom. Whether it is an iron deficiency or overload, tiredness is one of the most common features. Despite significant progress in diagnosing and treating iron pathologies, the approach to chronic fatigue syndrome in such patients is not precisely determined. Our study aims to present the current state of knowledge on fatigue in patients with deteriorated iron metabolism.

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.

Fatigue: a frequent and biologically based phenomenon in newly diagnosed celiac disease

Fatigue is increasingly recognized as a major complaint in patients with chronic inflammatory and autoimmune diseases. Although fatigue is assumed to represent a significant problem in celiac disease, existing knowledge is scarce, and opinions are conflicting. This study aimed to investigate the prevalence and severity of fatigue in patients with newly diagnosed celiac disease and compare it with healthy control subjects. Ninety patients with newly diagnosed celiac disease were compared with 90 age- and sex-matched healthy subjects. The primary endpoints were fatigue severity as measured by: the fatigue Visual Analog Scale (fVAS), the Fatigue Severity Scale (FSS), and the inverted Vitality subscale of the MOS36 (SF-36vs). Higher scores indicate more severe fatigue. Clinically relevant fatigue was determined using predefined cut-off values. Secondary endpoints were the associations between fatigue, and sex, age, depression, pain, and selected biochemical variables. The median (IQR) fVAS-scores were 43.0 (18.0–64.5) in patients, and 9.0 (2.0–16.0) in the control group (p < 0.001); and the FSS scores 3.8 (2.0–4.8) in patients, and 1.4 (1.0–1.9) in control subjects (p < 0.001). Inverted SF-36vs scores had a mean (SD) value of 58.8 (23.6) in patients, and 29.7 (14.3) in healthy subjects (p < 0.001). The presence of clinically relevant fatigue ranged from 41 to 50% in patients. Increased fatigue severity was associated with female sex, younger age, and elevated pain and depression scores, but not with levels of selected biochemical variables, including hemoglobin. Fatigue is a severe and frequent phenomenon in patients with untreated celiac disease.

How Should Pain, Fatigue, and Emotional Wellness Be Incorporated Into Treatment Goals for Optimal Management of Inflammatory Bowel Disease?

Early diagnosis and the optimal control of inflammation, with a continuous cycle of assessment, treatment, monitoring, and adjustment of therapy, is best practice for the management of inflammatory bowel disease. However, patients express frustration with ongoing challenging symptoms, often discordant with inflammation, including abdominal pain, fatigue, depression, anxiety, and emotional wellness; these are often not optimally addressed by inflammatory bowel disease clinicians due to lack of time or resources. This review will highlight the burden of these symptoms and issues, suggest ways of assessing these in clinical practice, highlight the importance of acknowledging and validating the symptoms and issues with patients, reassuring them that they are being heard, and discuss different possible models of service delivery for psychosocial support, from fully integrated gastropsychology models to referral pathways that optimize community support. We suggest the importance of the treat-to-target concept, where the target is not only control of inflammation but also emotional wellness.

Promoting psycho-social wellbeing for engaging inflammatory bowel disease patients in their care: an Italian consensus statement

BACKGROUND

Inflammatory bowel diseases (IBD) are remitting and relapsing diseases that mainly interest the gastrointestinal tract. IBD is associated with a condition of psycho-social discomfort that deeply compromises the quality of life and the competence of patient to be fully engaged in their self-management. As a consequence, effective care of IBD patients should include not only medical but also psychological support in order to improve patients' wellbeing. Although this, to date there is no standardized approach to promote psychological wellbeing of IBD patients in order to improve the perception of the quality of the care. To fill this gap, a consensus conference has been organized in order to define the psychosocial needs of IBD patients and to promote their engagement in daily clinical practice. This paper describes the process implemented and illustrates the recommendations deriving from it, which focus on the importance of a multidisciplinary approach in IBD management.

RESULTS

The consensus conference has been organized in three phases: (1) literature review about life experiences, engagement, and psychosocial needs of IBD patients; (2) workshops with IBD experts and patients' representatives; (3) drafting of statements and voting. Seventy-three participants were involved in the consensus conference, and sixteen statements have been voted and approved during the consensus process.

CONCLUSIONS

The main conclusion is the necessity of the early detection of - and, in case of need, intervention on- psycho-social needs of patients in order to achieve patient involvement in IBD care.

Trajectories of Fatigue in Inflammatory Bowel Disease

BACKGROUND

Fatigue is one of the most frequently reported symptoms by patients with inflammatory bowel disease (IBD), both during active disease phases as well as during clinical remission. This study addressed whether different trajectories of fatigue over time can be identified among patients with IBD. Subsequently, we compared the demographic and clinical characteristics between trajectories.

METHODS

The current study included 849 patients with IBD diagnosed with either Crohn disease (CD; n = 511) or ulcerative colitis (UC; n = 338) who visited the University Medical Center in Groningen (the Netherlands) at least 3 times during a 9-year follow-up. We conducted latent class growth analyses to identify distinct trajectories.

RESULTS

In all patients with IBD (and in the subgroup with CD), we found 5 trajectories for fatigue. In the UC subgroup, we found 4 fatigue trajectories. One trajectory present in both patients with CD (11.45%) and patients with UC (4.75%) was characterized by chronic elevated levels of fatigue across time. Women and parents were more prevalent in trajectories with higher fatigue severity. We also found significant associations among the fatigue trajectories with disease activity and psychological well-being.

CONCLUSIONS

The results clearly showed the existence of distinct fatigue paths over time in patients with IBD. Those reporting more chronic elevated levels of fatigue also reported greater disease activity and reduced well-being. Therefore, reducing disease activity may be important for the treatment of fatigue. In addition, given the significant association with well-being, it is possible that reducing fatigue may improve self-reported well-being.

Dissecting the fatigue experience: A scoping review of fatigue definitions, dimensions, and measures in non-oncologic medical conditions

Introduction

Fatigue is a prevalent and potentially debilitating symptom that impacts the health-related quality-of-life of individuals diagnosed with acute and chronic medical conditions. Yet, its etiologic mechanism is not fully understood. Additionally, the assessment and determination of the clinical meaning of fatigue and its multidimensionality may vary by medical condition.

Methods

A scoping literature review was conducted to investigate how fatigue is defined and measured, including its dimensions, in non-oncologic medical conditions. The PubMed database was searched using keywords.

Results

Overall, 8376 articles were screened at the title/abstract levels, where 293 articles were chosen for full-text review that mentioned fatigue or included fatigue measures. The review of the full text excluded 246 articles that did not assess at least one fatigue dimension using validated questionnaires and clinical tests. The final set included 47 articles. Physical fatigue was the most assessed fatigue dimension and the Multidimensional Fatigue Inventory was the most widely used questionnaire to assess fatigue in this review.

Limitations

This review was limited by including only English-language publications and using PubMed as the sole database for the search.

Conclusions

This review affirms that fatigue is a multidimensional construct, agnostic of medical condition, and that individual fatigue dimensions can be measured by validated clinical measures. Future research should focus on expanding the repertoire of clinical measures to assess specific fatigue dimensions.

•

The 27 different validated clinical measures used to assess fatigue and its dimensions; 20 instruments assessed the physical, 8 for mental, 7 cognitive, 5 for motivational, 2 for emotional, 1 peripheral, 1 for central, 1 psychosocial.

•

Physical was the most measured dimension, as assessed in 42 of 47 included articles.

•

This review affirms that fatigue is a multidimensional construct, agnostic of medical condition, and that individual fatigue dimensions can be measured by validate clinical measures.

Evaluation of the Unidimensional Fatigue Impact Scale (U-FIS) in Crohn's Disease: The Importance of Local Item Dependency

BACKGROUND AND PURPOSE

The Unidimensional Fatigue Impact Scale (U-FIS) was developed for use in a multiple sclerosis population. The aim was to determine whether the U-FIS is a valid tool for measuring the impact of fatigue in Crohn's disease (CD).

METHOD

CD patients completed the U-FIS as part of a validation study of the Crohn's Life Impact Questionnaire (CLIQ). Data were analyzed according to Rasch measurement theory (RMT).

RESULTS

Two hundred sixty-one completed U-FIS questionnaires were available for analysis. After rescoring the items to resolve disordered thresholds, all 22 items showed acceptable RMT fit. However, there was considerable local item dependency (LID).

CONCLUSION

The U-FIS did not provide unidimensional measurement in a sample of CD patients due to high levels of LID. Combining the three FIS outcomes into a single measure was not justified.

Stem Cell Therapy For The Treatment Of Crohn's Disease; Current Obstacles And Future Hopes. (Mini-Review)

BACKGROUND

Crohn's disease (CD) is an autoimmune disease of the gastrointestinal tract, characterized by relapsing and remitting courses. The disease is debilitating in nature with three prominent phenotypic clinical presentations; fistulizing, stenosing, and inflammatory. Stem cells offer a new hope for CD patients with modifying the immune response and progression of the healing process.

AIM

This mini-review discusses the role of stem cells in treating CD, their effectiveness as a new therapy and their current limitations faced.

METHODS

The author conducted a literature review on recent randomized controlled trials and cohort studies concerned with the topic in question using the following keywords (Crohn's Disease, perianal fistula, Stem cell therapy, mesenchymal stem cells, remission).

RESULTS

Clinical trials show that the stem cells are more effective in the CD associated complex perianal fistula than the CD enteritis. Till the time being, there are no standardized guidelines regarding; dose of stem cells used, number of doses administered, route of administration, type of stem cells used. Only one group of researchers proposed a standardized procedure for injecting mesenchymal stem cells in complex perianal fistula, according to their own experience in clinical trials. Moreover, mesenchymal stem cells and their related types (placental, adipose tissue, umbilical tissue, etc.) are the most safe and effective in clinical trials. Currently; the commercially available mesenchymal stem cells preparation (Darvadstrocel (Cx601)) is the only one approved by The United States Food and Drug Administration (FDA) for clinical use in refractory CD associated complex perianal fistula.

CONCLUSIONS

Stem cell therapy (SCT) shows promise in; inducing remission in refractory Crohn's colitis, and perianal fistula, but further research is required before SCT could be applied to clinical practice guidelines.

Supported online self-management versus care as usual for symptoms of fatigue, pain and urgency/incontinence in adults with inflammatory bowel disease (IBD-BOOST): study protocol for a randomised controlled trial

BACKGROUND

Despite being in clinical remission, many people with inflammatory bowel disease (IBD) live with fatigue, chronic abdominal pain and bowel urgency or incontinence that limit their quality of life. We aim to test the effectiveness of an online self-management programme (BOOST), developed using cognitive behavioural principles and a theoretically informed logic model, and delivered with facilitator support.

PRIMARY RESEARCH QUESTION

In people with IBD who report symptoms of fatigue, pain or urgency and express a desire for intervention, does a facilitator-supported tailored (to patient needs) online self-management programme for fatigue, pain and faecal urgency/incontinence improve IBD-related quality of life (measured using the UK-IBDQ) and global rating of symptom relief (0-10 scale) compared with care as usual?

METHODS

A pragmatic two-arm, parallel group randomised controlled trial (RCT), of a 12-session facilitator-supported online cognitive behavioural self-management programme versus care as usual to manage symptoms of fatigue, pain and faecal urgency/incontinence in IBD. Patients will be recruited through a previous large-scale survey of unselected people with inflammatory bowel disease. The UK Inflammatory Bowel Disease Questionnaire and global rating of symptom relief at 6 months are the co-primary outcomes, with multiple secondary outcomes measured also at 6 and 12 months post randomisation to assess maintenance. The RCT has an embedded pilot study, health economics evaluation and process evaluation. We will randomise 680 patients, 340 in each group. Demographic characteristics and outcome measures will be presented for both study groups at baseline. The UK-IBDQ and global rating of symptom relief at 6 and 12 months post randomisation will be compared between the study groups.

DISCUSSION

The BOOST online self-management programme for people with IBD-related symptoms of fatigue, pain and urgency has been designed to be easily scalable and implemented. If it is shown to improve patients' quality of life, this trial will enable clinicians and patients to make informed management decisions. This is the first trial, to our knowledge, focused on multiple symptoms prioritised by both people with IBD and health professionals.

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 IBD-F Patient Self-Assessment Scale Accurately Depicts the Level of Fatigue and Predicts a Negative Effect on the Quality of Life of Patients With IBD in Clinical Remission

BACKGROUND

Fatigue is highly prevalent among patients with inflammatory bowel disease (IBD) and may have an unfavorable impact on quality of life (QoL). The IBD-Fatigue scale (with components SCORE1 and SCORE2) is a recently developed disease-specific questionnaire. We sought to validate a Greek version of IBD-F and use it to assess the severity and characteristics of fatigue and its effect on QoL in our study population.

METHODS

The IBD-F scale was validated and used to obtain fatigue-related data from patients with IBD attending a tertiary care hospital. Correlations with other fatigue and QoL instruments were performed.

RESULTS

The Greek IBD-F showed high internal consistency and test-retest reliability (Cronbach's alpha = 0.901/0.966 and intraclass correlation coefficient = 0.876/0.895 for SCORE1/SCORE2, respectively). A SCORE1 >7.5 suggested "significant" fatigue. In a cohort of 157 patients (mean age = 35.8 y; male patients = 52.2%; patients with Crohn disease = 65.6%), both SCORE1 and SCORE2 were significantly associated with Crohn disease (odds ratio [OR] = 4.17; 95% confidence interval [CI], 2.05-8.47; b = 8.5; 95% CI, 2.8-14.1, respectively), female sex (OR = 7.27; 95% CI, 3.19-16.6; b = 15.3; 95% CI, 9-21.6), and Harvey-Bradshaw Index/Simple Clinical Colitis Activity Index score (OR = 1.22; 95% CI, 1.06-1.39; b = 1.8; 95% CI, 0.9-2.8). A SCORE1 >7.5 was present in 46% of patients in remission, and 82% of patients with a baseline SCORE1 >7.5 remained fatigued at serial measurements. The SCORE1 was significantly associated with impaired QoL (P < 0.001).

CONCLUSIONS

The validated IBD-F scale is a useful and applicable instrument for use in the IBD population. A large proportion of patients have significant fatigue, which is maintained longitudinally, independent of inflammatory activity. Fatigue impairs QoL, thus necessitating interventions that may lead to its amelioration in the IBD population.

Alterations in Fecal Microbiomes and Serum Metabolomes of Fatigued Patients With Quiescent Inflammatory Bowel Diseases

BACKGROUND & AIMS

Fatigue is frequent and disabling in patients with inflammatory bowel diseases (IBD) but its mechanisms are poorly understood. We investigated alterations in fecal microbiomes and serum metabolomes and proteomes in patients with quiescent IBD, with vs without fatigue.

METHODS

We performed a prospective observational study of patients (44% women; mean age, 39.8 y) with clinically and endoscopically quiescent Crohn's disease (n = 106) or ulcerative colitis (n = 60) at a tertiary hospital, from March 2016 through December 2018. Fatigue was assessed using the functional assessment of chronic illness therapy-fatigue scoring system and defined as a score of 43 or less. We performed metabolomic analysis of serum samples using liquid chromatography-mass spectrometry methods and proteomic analysis using multiplex proximity extension assay (PEA) technology. Stool samples were obtained from 50 patients and analyzed by shotgun metagenomic sequencing on Illumina HiSeq platform.

RESULTS

Of the 166 study participants, 91 (55%) were fatigued. Serum samples from patients with fatigue (n = 59) did not have significant increases in levels of inflammatory cytokines compared with serum samples from nonfatigued patients (n = 72). We found a statistically significant difference in a cluster of 18 serum metabolites between patients with fatigue (n = 84) vs without fatigue (n = 72) (P = .033); serum samples from patients with fatigue had significant reductions in levels of methionine (P = .020), tryptophan (P = .042), proline (P = .017), and sarcosine (P = .047). Fecal samples from patients with fatigue had a less diverse gut microbiome, with significant reductions in butyrate-producing bacteria, including Faecalibacterium prausnitzii (P = .0002, q =.007) and Roseburia hominis (P = .0079, q = 0.105). This fatigue-like microbiome was associated with fatigue scales and correlated with progressive depletion of metabolites from serum samples.

CONCLUSIONS

In an analysis of fecal and serum samples from 166 patients with IBD, we found alterations in serum metabolites and fecal microbes that were associated with fatigue.

Fatigue in inflammatory bowel disease: a problematic ailment

PURPOSE OF REVIEW

Fatigue, a protean complaint encompassing both physical, mental exhaustion but also demotivation, has shown to effect quality of life in patients with inflammatory bowel disease (IBD). Here we present a review of the literature as it relates to IBD-associated fatigue. Moreover, we present the common causes attributed to fatigue and present an algorithmic approach to the assessment of fatigue. Finally, we report data regarding potential management strategies for IBD-associated fatigue.

RECENT FINDINGS

Unfortunately, owing to its multidimensional nature and multifactorial causes, patients with IBD may continue to report fatigue despite optimization of disease management, replenishment of nutritional deficiencies, or management of coexistent disorders. Management likely requires a multidisciplinary approach.

SUMMARY

The majority of patients with IBD report fatigue symptoms both in setting of active disease but also during the course of remission. Fatigue is a multidimensional complaints, and management likely requires a multidisciplinary approach. Herein, we present a framework for the management and assessment of fatigue in IBD.

Fatigue in Inflammatory Bowel Diseases: Etiologies and Management

Fatigue is a burdensome, multidimensional, and multifactorial symptom that is associated with a wide array of chronic illnesses, specifically occurring in nearly 50% of patients with inflammatory bowel disease (IBD). Although common, given its subjective nature, physicians often under-recognize and undertreat this debilitating symptom. There are multiple etiologies that can contribute to fatigue in patients with IBD, including disease activity, anemia, medications, psychosomatic symptoms, and alterations to the gut–brain axis. The management of fatigue in IBD can be challenging, as it is often times multifaceted. In this review, we summarize the available tools for the diagnosis and measurement of fatigue, discuss etiologies, and make recommendations for their management. We identify knowledge gaps for the workup and treatment of fatigue and propose an algorithm to aid physicians in the evaluation and management of fatigue in this unique population. However, future research is needed to address several areas of knowledge deficits and improve the management of fatigue in IBD.

The relationship between the symptom of fatigue and the functioning of patients with inflammatory bowel diseases after surgery

INTRODUCTION

The occurrence of fatigue in patients suffering from inflammatory bowel diseases (IBD) is influenced by pain, frequent bowel movements, stress associated with symptoms and time of their occurrence reaction of surroundings, fear for their own health, sleep disturbances, side effects of pharmacological treatment, physical and mental exhaustion, hindered social contacts and difficulties at work.

AIM

To evaluate the fatigue and the assessment of functioning of patients with IBD, who were treated surgically.

MATERIAL AND METHODS

To evaluate the functioning of patients, a Polish version of the Inflammatory Bowel Disease Questionnaire was used. To evaluate the occurrence of fatigue in studied subjects, a Polish version of the Functional Assessment of Chronic Illness Therapy - Fatigue Scale was used. The activity of disease was evaluated with the use of the Crohn's Disease Activity Index for patients with Crohn's disease (CD) and the Clinical Activity Index for patients with ulcerative colitis (UC).

RESULTS

Before surgery, there was no significant difference between CD and UC patients, with regard to the mean FACIT-F (28.76 for CD and 28.76 for UC, p = 0.72). Also, after surgery, there was no significant difference between CD and UC patients, with regard to the mean FACIT-F (14.8 for CD and 16.0 for UC, p = 0.71). The IBD patients who underwent surgery for CD and UC had significantly lower FACIT-F scores compared to the patients before the surgery (p = 0.001 and p = 0.0001, respectively). IBD patients who underwent surgery for CD and UC had significantly better functioning and higher IBDQ total scores compared to the patients before the surgery.

CONCLUSIONS

Surgical treatment significantly reduces the fatigue symptom in patients with IBD. The severity of fatigue correlates with disease activity and functioning in the respective areas.

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.

Simplification of Validated Patient-Reported Outcome Instruments in Inflammatory Bowel Disease

Objectives

Improving health-related quality of life (HRQoL) is a major treatment goal for inflammatory bowel disease (IBD) patients. Tools to measure HRQoL, including the Pittsburgh Sleep Quality Index and the Short Inflammatory Bowel Diseases Questionnaire, are lengthy and rely on recall. This prospective, proof-of-concept pilot study assessed the feasibility, reliability, and validity of daily, simplified HRQoL and sleep quality data collection using mobile technologies in patients with IBD.

Methods

Adult IBD patients were recruited from our center. Daily HRQoL and sleep quality were assessed using visual analog scale (VAS) surveys, and pain was assessed using the Wong-Baker FACES Pain Rating Scale (WBS). HRQoL and sleep were assessed on days 1, 14, and 28 of the study using the short IBD Questionnaire (SIBDQ) and Pittsburgh Sleep Quality Index (PSQI). Correlation between the daily instruments and the biweekly validated instruments were assessed using the Pearson correlation coefficient.

Results

One hundred patients were enrolled. The correlation between mean global assessment VAS score over 2 weeks and PSQI score taken at 14 days was moderate (r = 0.62, P &lt; 0.0001). The correlation over the same time interval between mean WBS score and SIBDQ score was strong (r = −0.71, P &lt; 0.0001), and the correlation between mean sleep VAS score and PSQI score was moderate (r = −0.55, P &lt; 0.0001).

Conclusions

This study demonstrates the potential for electronic quality of life, sleep quality, and pain assessments as feasible, reliable, and valid tools in IBD patients. Intermittent administration of these simplified electronic assessments may be useful in further reducing patient survey burden without significantly compromising their utility.

Prevalence and Factors Associated With Fatigue in Patients With Inflammatory Bowel Disease: A Multicentre Study

BACKGROUND AND AIMS

The aims of this study were to determine the prevalence of fatigue in patients with inflammatory bowel disease [IBD], to identify the factors associated with fatigue and its severity, to assess the impact of fatigue on quality of life [QoL], and to evaluate the relationship between fatigue and sleep disorders.

METHODS

This was a prospective multicentre study conducted at 22 Spanish centres. Consecutive patients followed at IBD Units were included. Fatigue was evaluated with the Fatigue Severity Scale [FSS] and the Fatigue Impact Scale [FIS]. Quality of life and sleep quality were assessed using the IBD Questionnaire-Short Form [IBDQ-9] and the Pittsburgh Sleep Quality Index [PSQI], respectively.

RESULTS

A total of 544 consecutive adult IBD patients were included [50% women, mean age 44 years, 61% Crohn's disease]. The prevalence of fatigue was 41% (95% confidence interval [CI] = 37-45%). The variables associated with an increased risk of fatigue were: anxiety [OR = 2.5, 95% CI = 1.6-3.7], depression [OR = 2.4, 95% CI = 1.4-3.8], presence of extraintestinal manifestations [EIMs] [OR = 1.7, 95% CI = 1.1-2.6], and treatment with systemic steroids [OR = 2.8, 95% CI = 1.4-5.7]. The presence of EIMs [regression coefficient, RC = 8.2, 95% CI = 2.3-14.2], anxiety [RC = 25.8, 95% CI = 20.0-31.5], depression [RC = 30.6, 95% CI = 24.3-37.0], and sleep disturbances [RC = 15.0, 95% CI = 9.3-20.8] were associated with severity of fatigue. Patients with fatigue had a significantly decreased IBDQ-9 score [p < 0.001].

CONCLUSIONS

The prevalence of fatigue in IBD patients is remarkably high and has a negative impact on QoL. Therapy with systemic steroids is associated with an increased risk of fatigue. The severity of fatigue is associated with anxiety, depression, sleep disorders, and the presence of EIMs. Fatigue was not associated with anaemia, disease activity or anti-TNF therapy.

European Crohn's and Colitis Organisation Topical Review on Complementary Medicine and Psychotherapy in Inflammatory Bowel Disease

Patients with inflammatory bowel disease [IBD] increasingly use alternative and complementary therapies, for which appropriate evidence is often lacking. It is estimated that up to half of all patients with IBD use various forms of complementary and alternative medicine during some point in their disease course. Considering the frequent use of such therapies, it is crucial that physicians and patients are informed about their efficacy and safety in order to provide guidance and evidence-based advice. Additionally, increasing evidence suggests that some psychotherapies and mind-body interventions may be beneficial in the management of IBD, but their best use remains a matter of research. Herein, we provide a comprehensive review of some of the most commonly used complementary, alternative and psychotherapy interventions in IBD.

Population-based normative data for the inflammatory bowel disease fatigue scale - IBD-F

OBJECTIVE

Fatigue is a common concern among patients with inflammatory bowel disease (IBD). The Inflammatory Bowel Disease Fatigue (IBD-F) scale was developed in 2014 together with patients with IBD. The IBD-F comprises five questions about the frequency and severity of fatigue followed by 30 questions about the experience and impact of fatigue. All questions have generic character. Normative values are needed if the IBD-F scale is to be used extensively. This study aims to generate normative values for the IBD-F scale in a Danish background population.

MATERIALS AND METHODS

An age- and gender-stratified random sample of 3460 Danes was drawn from the total population. The IBD-F and a few socio-demographic questions were administered electronically.

RESULTS

Of the 3460 drawn individuals, 2952 citizens with electronic access were invited to participate, 1925 (65.2%) citizens accepted the invitation, and 1761 (59.7%) completed the IBD-F questionnaire. Overall, women had more fatigue than men (the frequency and severity, 7.2 vs. 6.6; p < .001) (the experience and impact, 17.0 vs. 13.5; p < .001). Fatigue was most marked for citizens <50 and ≥80 years old. Having no education, working part time, and morbidity were factors associated with more fatigue. Co-habitation was associated with less fatigue. The internal consistency in this population revealed Cronbach's alpha values >0.85.

CONCLUSIONS

The IBD-F scale can be used in the background population and this study provides normative data for fatigue. Fatigue was higher for women and specific age groups. Several socio-demographic and morbidity variables were associated with fatigue.

Fatigue in IBD: epidemiology, pathophysiology and management

Fatigue is an important clinical problem in patients with IBD, affecting nearly 50% of patients in clinical remission and > 80% of those with active disease. The resulting decrease in quality of life and impaired work productivity and functioning contribute markedly to the societal costs of fatigue. However, despite the burden and effects of fatigue, little is known about its aetiology and pathophysiology, which impairs our ability to effectively treat this symptom. Here, we review the theories behind the development of fatigue in IBD and the role of contributing factors, including nutritional deficiency, inflammation and altered metabolism. We also explore the potential role of the gut microbiome in mediating fatigue and other psychological symptoms through the gut-brain axis. We discuss the efficacy of nutrient repletion and various psychological and pharmacological interventions on relieving fatigue in patients with IBD and expand the discussion to non-IBD-related fatigue when evidence exists. Finally, we present a therapeutic strategy for the management of fatigue in IBD and call for further mechanistic and clinical research into this poorly studied symptom.

Examination of the relationship between disease activity and patient-reported outcome measures in an inflammatory bowel disease cohort

BACKGROUND

The extent to which disease activity impacts patient-reported outcomes (PRO) is unclear.

AIMS

To examine the relationship between disease activity and PRO.

METHODS

Adult inflammatory bowel disease (IBD) patients attending a tertiary clinic from May to June 2015 were included. Assessment of disease activity (Simple Clinical Colitis Activity Index (SCCAI), Harvey Bradshaw Index (HBI)), IBD knowledge (CCKNOW), medication adherence (MMAS8), psychological distress (Hospital Anxiety and Depression Scale (HADS)), work productivity (WPAI) and quality of life (IBDQ) was performed to investigate any correlations between disease activity and PRO.

RESULTS

A total of 81 participants was included: 49% female, 57% Crohn disease (CD), 38% ulcerative colitis (UC) and 5% IBD-unclassified, with a median age of 34 years. At least mild levels of depression were present in 21 of 81 (26%) of patients; 37 of 81 (46%) expressed some level of anxiety. A moderate-to-strong correlation was found between disease activity and depression in UC (r = 0.84, P = 0.002) but not in CD (r = 0.53, P = 0.29). Disease activity correlated with: overall work impairment due to health (r = 0.85, P = 0.001), health-related impairment while working (r = 0.76, P = 0.02) and percentage of activity impaired due to health (r = 0.83, P = 0.002) in UC only.

CONCLUSIONS

Disease activity significantly affects mood and work productivity in patients with UC. Monitoring patients' ability to function and work, rather than minimising disease activity alone, should become a routine part of IBD care.

Unmet Needs in IBD: the Case of Fatigue

Fatigue is a highly prevalent but relatively ignored problem in IBD patients. It is one of the most burdensome symptoms to the patient with an important impact on the quality of life. Therefore, fatigue is a highly relevant patient-reported outcome that should be included not only in disease activity measurement but also in the endpoints of clinical trials in IBD. However, most of the currently available scoring systems to quantify fatigue are not specifically designed for patients with IBD and none of them has undergone a complete validation process for IBD-related fatigue. Fatigue is more prevalent in patients with active disease and may improve or disappear when remission is reached. Far more complex is the persistence or onset of fatigue in quiescent IBD which presents in up to 40% of the patients. In this subgroup of patients, fatigue can be related to smoldering systemic inflammation, a poor sleep quality, anemia, nutritional deficiencies, or comorbidities. In most cases, however, no direct cause can be identified. The lack of knowledge on the mechanisms that drive fatigue in IBD hamper the development of specific drugs to treat the condition and only psychological support can be offered to the patient. Rodent models are indispensable to increase our understanding of the molecular pathways that lead to fatigue in chronic intestinal inflammation, and to develop novel therapies.

Gut-brain actions underlying comorbid anxiety and depression associated with inflammatory bowel disease

IntroductionInflammatory bowel disease (IBD) is a chronic relapsing and remitting disorder characterised by inflammation of the gastrointestinal tract. There is a growing consensus that IBD is associated with anxiety- and depression-related symptoms. Psychological symptoms appear to be more prevalent during active disease states with no difference in prevalence between Crohn's disease and ulcerative colitis. Behavioural disturbances including anxiety- and depression-like symptoms have also been observed in animal models of IBD.

RESULTS

The likely mechanisms underlying the association are discussed with particular reference to communication between the gut and brain. The close bidirectional relationship known as the gut-brain axis includes neural, hormonal and immune communication links. Evidence is provided for a number of interacting factors including activation of the inflammatory response system in the brain, the hypothalamic-pituitary-adrenal axis, and brain areas implicated in altered behaviours, changes in blood brain barrier integrity, and an emerging role for gut microbiota and response to probiotics in IBD.DiscussionThe impact of psychological stress in models of IBD remains somewhat conflicted, however, it is weighted in favour of stress or early stressful life events as risk factors in the development of IBD, stress-induced exacerbation of inflammation and relapse.

CONCLUSION

It is recommended that patients with IBD be screened for psychological disturbance and treated accordingly as intervention can improve quality of life and may reduce relapse rates.

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.

Inflammatory Bowel Diseases Can Adversely Impact Domains of Sexual Function Such as Satisfaction with Sex Life

BACKGROUND

Aspects of sexual health, which can be adversely affected by chronic disease, have been inadequately explored in inflammatory bowel disease (IBD).

AIMS

We evaluated patient-reported interest in sexual activity and satisfaction with sex life in a large cohort of IBD patients.

METHODS

We conducted a cross-sectional study within the Crohn's and Colitis Foundation Partners Internet cohort. Sequential participants completed a 6-question supplemental online survey to examine sexual interest and satisfaction using the Patient-Reported Outcome Measurement Information System^® (PROMIS^®) Sexual Function and Satisfaction measures. One-sample t tests were used to compare interest and satisfaction scores to general population norms.

RESULTS

Among 2569 individuals, 1639 had Crohn's disease (CD), 930 had ulcerative colitis (UC) or indeterminate colitis, and 71% were women. Mean PROMIS scores for sexual interest were comparable to the general US population in men (CD: 49 and UC: 50 vs. population mean 50) and women (CD: 41 and UC: 40 vs. population mean 42). However, sexual satisfaction scores were lower than the US population in men (CD: 48 and UC: 48 vs. 51) and women (CD: 47 and UC: 46 vs. 49), p < 0.01 for both. Older age, disease activity, depression, anxiety, and pain were associated with lower interest and satisfaction and lowered IBD-specific quality of life.

CONCLUSIONS

IBD patients in a large online survey had similar levels of sexual interest but decreased sexual satisfaction compared to the general population. Exploring these sexual health domains during clinical encounters can aid in improving IBD quality of life.

Associations between chronotype, sleep disturbances and seasonality with fatigue and inflammatory bowel disease symptoms

Growing number of studies suggests link between circadian rhythms and inflammatory bowel diseases (IBD) manifestation. We hypothesize that: 1) IBD are associated with increased eveningness and sleep disturbances; 2) eveningness and sleep disturbances are related to more severe IBD symptoms. In total, 129 participants were enrolled to this study, divided into three groups: 34 Crohn's disease (CD) patients, 38 ulcerative colitis (UC) patients and 57 healthy controls (HC) group. They all fulfilled a questionnaire, consisting of the Composite Scale of Morningness (CSM), Seasonal Pattern Assessment Questionnaire (SPAQ), Pittsburgh Sleep Quality Index, Inflammatory Bowel Disease Questionnaire (IBDQ) and Multidimensional Fatigue Inventory (MFI). Multiple regression models controlled for age and sex revealed that in CD group higher eveningness measured with CSM was associated with higher general fatigue, physical fatigue, mental fatigue and reduced motivation measured by MFI. Lower CSM morning affect is associated with greater general fatigue, physical fatigue and more reduced activity. Greater seasonality scores are associated with increased physical fatigue and more reduced activity and motivation. Lower sleep quality measured with PSQI is associated with higher physical fatigue and more reduced activity. Correlational analysis revealed that higher seasonality and lower sleep quality are associated with increased systemic and bowel symptoms and decreased emotional and social functions measured with IBDQ. In UC group, eveningness is associated with greater general fatigue, physical fatigue and more reduced activity. Higher CSM morning affect is associated with decreased general fatigue, physical fatigue and less reduced activity. Higher CSM circadian preference scores are associated with decreased general and physical fatigue, and less reduced activity. Increased seasonality is associated with more physical fatigue. Lower sleep quality is associated with greater general and physical fatigue. To our best knowledge this is the first study evaluating associations between chronotype and sleep disturbances with IBD symptoms. We have found that chronotype preferences, whose role in IBD has been until now overlooked, may be one of the important factors contributing to fatigue in this clinical group.

Living with Crohn's disease: an exploratory cross-sectional qualitative study into decision-making and expectations in relation to autologous haematopoietic stem cell treatment (the DECIDES study)

BACKGROUND/OBJECTIVES

Severe Crohn's disease impacts negatively on individual quality of life, with treatment options limited once conventional therapies have been exhausted. The aim of this study was to explore factors influencing decision-making and expectations of people considering or participating in the Autologous Haematopoietic Stem Cell Treatment trial.

METHODS

An international, cross-sectional qualitative study, involving semistructured face to face interviews across five sites (four UK and one Spain). 38 participants were interviewed (13 men, 25 women; age range 23-67 years; mean age 37 years). The mean age at diagnosis was 20 years. Interviews were audio recorded and transcribed verbatim and transcripts were analysed using a framework approach.

RESULTS

Four themes emerged from the analysis: (1) 'making your mind up'-a determination to receive stem cell treatment despite potential risks; (2) communicating and understanding risks and benefits; (3) non-participation-your choice or mine? (4) recovery and reframing of personal expectations.

CONCLUSIONS

Decision-making and expectations of people with severe Crohn's disease in relation to autologous haematopoietic stem cell treatment is a complex process influenced by participants' histories of battling with their condition, a frequent willingness to consider novel treatment options despite potential risks and, in some cases, a raised level of expectation about the benefits of trial participation. Discussions with patients who are considering novel treatments should take into account potential 'therapeutic misestimation', thereby enhancing shared decision-making, informed consent and the communication with those deemed non-eligible.

White Paper AGA: The Impact of Mental and Psychosocial Factors on the Care of Patients With Inflammatory Bowel Disease

Patients with chronic medically complex disorders like inflammatory bowel diseases (BD) often have mental health and psychosocial comorbid conditions. There is growing recognition that factors other than disease pathophysiology impact patients' health and wellbeing. Provision of care that encompasses medical care plus psychosocial, environmental and behavioral interventions to improve health has been termed "whole person care" and may result in achieving highest health value. There now are multiple methods to survey patients and stratify their psychosocial, mental health and environmental risk. Such survey methods are applicable to all types of IBD programs including those at academic medical centers, independent health systems and those based within independent community practice. Once a practice determines that a patient has psychosocial needs, a variety of resources are available for referral or co-management as outlined in this paper. Included in this white paper are examples of psychosocial care that is integrated into IBD practices plus innovative methods that provide remote patient management.

Cognitive behavioural therapy for the management of inflammatory bowel disease-fatigue with a nested qualitative element: study protocol for a randomised controlled trial

BACKGROUND

Fatigue is one of the most prevalent and burdensome symptoms for patients with inflammatory bowel disease (IBD). Although fatigue increases during periods of inflammation, for some patients it persists when disease is in remission. Compared to other long-term conditions where fatigue has been extensively researched, optimal management of fatigue in patients with IBD is unknown and fatigue has rarely been the primary outcome in intervention studies. To date, interventions for the management of IBD-fatigue are sparse, have short-term effects and have not been implemented within the existing health system. There is a need to integrate current best evidence across different conditions, patient experience and clinical expertise in order to develop interventions for IBD-fatigue management that are feasible and effective. Modifying an existing intervention for patients with multiple sclerosis, this study aims to assess the feasibility and initial estimates of efficacy of a cognitive behavioural therapy (CBT) intervention for the management of fatigue in patients with IBD.

METHODS

The study will be a two-arm pilot randomised controlled trial. Patients will be recruited from one outpatient IBD clinic and randomised individually to either: Group 1 (CBT manual for the management of fatigue, one 60-min session and seven 30-min telephone/Skype sessions with a therapist over an eight-week period); or Group 2 (fatigue information sheet to use without therapist help). Self-reported IBD-fatigue (Inflammatory Bowel Disease-Fatigue Scale) and IBD-quality of life (United Kingdom Inflammatory Bowel Disease Questionnaire) and self-reported disease activity will be collected at baseline, three, six and 12 months post randomisation. Illness perceptions, daytime sleepiness, anxiety and depression explanatory variables will be collected only at three months post randomisation. Clinical and sociodemographic data will be retrieved from the patients' medical notes. A nested qualitative study will evaluate patient and therapist experience, and healthcare professionals' perceptions of the intervention.

DISCUSSION

The study will provide evidence of the feasibility and initial estimates of efficacy of a CBT intervention for the management of fatigue in patients with IBD. Quantitative and qualitative findings from the study will contribute to the development and implementation of a large-scale randomised controlled trial assessing the efficacy of CBT interventions for IBD-fatigue.

Fatigue in a population-based cohort of patients with inflammatory bowel disease 20 years after diagnosis: The IBSEN study

OBJECTIVE

Fatigue is a major concern for patients with ulcerative colitis (UC) and Crohn's disease (CD), but evidence from population-based studies regarding fatigue in long-standing inflammatory bowel disease (IBD) patients is scarce. Our aims were to assess fatigue scores and the prevalence of chronic fatigue in IBD patients 20 years after diagnosis and to identify variables associated with fatigue in this cohort.

METHODS

Twenty years after diagnosis, patients from a cohort with incident IBD were invited to a follow-up visit that included a structured interview, a clinical examination, laboratory tests and the Fatigue Questionnaire (FQ). Fatigue scores were obtained, and factors associated with fatigue were assessed via linear and logistic regression analyses.

RESULTS

Of the 599 invited patients, 440 (73.5%) completed the FQ. Among those with active disease, we found significantly higher fatigue scores than among those with quiescent disease (fatigue scores: UC 17.1 versus 12.4, p < .001, and CD 17.5 versus 13.3, p < .001). The fatigue scores of those with quiescent disease were comparable with those of the reference population. Chronic fatigue was more frequent among IBD patients than in the reference population. Factors associated with fatigue included self-perceived disease activity, poor sleep quality, anxiety and depression.

CONCLUSION

At 20 years after IBD diagnosis, fatigue scores were higher and chronic fatigue was more frequent among IBD patients with active disease than in the reference population and among those with quiescent IBD. Subjectively perceived disease activity, sleep quality, anxiety and depression were associated with fatigue in IBD patients.

The contribution of clinical and psychosocial factors to fatigue in 182 patients with inflammatory bowel disease: a cross-sectional study

BACKGROUND

Fatigue is a frequently reported and predominant symptom experienced by patients with inflammatory bowel disease (IBD) and its impact has been associated with poorer quality of life (QoL). The complex interplay between disease-related variables and potentially modifiable psychosocial factors in IBD-fatigue has yet to be unravelled.

AIM

To evaluate the contribution of clinical, sociodemographic and psychosocial factors to the severity and impact of IBD-fatigue and QoL.

METHOD

In a cross-sectional study, 182 patients with IBD were recruited from three tertiary referral hospitals' out-patient clinics in London. Fatigue was assessed utilising the Inflammatory Bowel Disease-Fatigue Scale (IBD-F), the Multidimensional Fatigue Inventory (MFI); and QoL by the Inflammatory Bowel Disease Questionnaire (IBDQ). Patients completed self-report questionnaires evaluating emotional, cognitive and behavioural factors potentially correlated with fatigue. Sociodemographic data were collected. Disease-related and laboratory data were retrieved from patients' hospital electronic medical records.

RESULT

In hierarchical regression models, disease activity was the only clinical factor consistently associated with severity and impact of fatigue and QoL (P = 0.01). More negative fatigue perceptions were significantly associated with greater IBD-F1 scores (P = 0.01). When controlling for clinical factors (disease activity and anti-TNF therapy), negative perceptions of fatigue, and all-or-nothing and avoidance behaviours explained an additional 41% of the variance in fatigue impact (IBD-F2).

CONCLUSIONS

Apart from disease activity, emotional and behavioural factors and patients' negative fatigue perceptions may be key factors to be addressed. Further exploration of these factors in longitudinal and intervention studies may help to develop effective models of fatigue management.

Fatigue in type 1 diabetes: A systematic review of Observational studies

AIM

To systematically review the literature on fatigue in people with type 1 diabetes.

METHODS

In the period from April to June 2015 and with an updated search in May 2016, eight electronic databases as well as the grey literature were searched. Studies of all types of design were included if they reported data on fatigue in adult people with type 1 diabetes. All studies were assessed for quality.

RESULTS

Out of 4259 references (including grey literature), 10 papers were reviewed in full. Three of these papers investigated fatigue as the primary endpoint, and one was assessed to be high quality. Two papers provided a definition of fatigue. Prevalence estimates ranged from 23 to 40%, dependent on the cut-off used. Six different questionnaires were used to measure fatigue/vitality and these were only validated to a limited extent in a diabetes population. Several demographic, personal and clinical factors were associated with fatigue, but the results were conflicting.

CONCLUSIONS

Few studies have been published that investigate fatigue in type 1 diabetes and there is a large variability in findings due to different measurement methods and factors investigated. There is still an unmet need to understand what contributes to fatigue in these patients through rigorous research.
