A population-based study of fatigue and sleep difficulties in inflammatory bowel disease

Patients' perceptions of quality of care and follow-up in inflammatory bowel disease

BACKGROUND AND AIMS

Quality of care (QoC) has gained increased attention in IBD. A better QoC has, historically, been linked to improved treatment outcomes. Even so, factors of equal importance to patients may be quality of life (QoL), patient-physician communication and access to care. Recent surveys suggest that IBD care in Europe is suboptimal.

METHODS

Patients were recruited from nine hospitals in the south-eastern and western part of Norway as a part of an observational, multicenter study In addition to clinical and socio-demographic factors; a purposely designed 26 item questionnaire was used to quantify aspects related to IBD care, including QoC. Moreover, the Fatigue Questionnaire (FQ) was used to investigate fatigue.

RESULTS

In total, 411 patients were included. Of these, 231 were diagnosed with CD and 180 with UC. Furthermore, 86.1% (354/411) were satisfied with the quality of IBD follow-up and only 4.1% (17/411) were dissatisfied. Most dissatisfaction was related to: lack of focus on personal relations (18.2%), HRQoL (15.1%), general practitioner knowledge of IBD (13.9%), ability to talk about important topics (7.8%), and hospital discharge communication (9.4%). Higher age and longer disease duration was associated with improved QoC scores in both UC and CD. Fatigue was associated with decreased QoC scores in both diagnoses.

CONCLUSIONS

Patients are satisfied with quality of care in IBD. However, communication seems to be an important area of improvement - not only related to patient-physician communication, but also to transitional communication between different health-care levels.

Sleep disturbances in Japanese patients with inflammatory bowel disease and their impact on disease flare

Background

Several studies have reported a significant association between sleep disturbance and inflammatory bowel disease (IBD). The aim of the present study is to compare the clinical characteristics and the health-related quality of life (HR-QOL) of Japanese IBD patients with or without sleep disturbances, and to investigate the risk factors for disease flare in these patients.

Methods

IBD patients were asked to complete a self-administered questionnaire including the Pittsburg sleep quality index and the 8-item short-form health survey. The information about disease flare within 1 year from enrollment in the study was analyzed with a multiple logistic regression model to identify risk factors for IBD flare-ups.

Results

The prevalence of sleep disturbances was 44.1 % (60 out of 136 IBD patients). Use of sleep medications was significantly higher in IBD patients with sleep disturbances whereas use of immuno modulators was significantly higher in IBD patients without sleep disturbances. The scores from all HR-QOL domains were significantly lower in patients with sleep disturbances than in patients without sleep disturbances. Fifty-one patients (37.5 %) had disease flare within 1 year from enrollment in the study and sleep disturbances were identified as a significant risk factor for disease flare (OR 3.09, 95 % CI 1.47–6.43).

Conclusions

Our results indicate that sleep disturbances are common in Japanese IBD patients and are associated with poorer HR-QOL. Since the presence of sleep disturbances is a significant risk factor for IBD flare-ups, we encourage physicians to perform a careful examination of sleep disturbances in IBD patients.

Pain may be an important factor to consider in inflammatory bowel disease patients troubled by fatigue

BACKGROUND

Pain has been associated with fatigue in many chronic diseases, but data are not available for inflammatory bowel disease (IBD). The aim of this study was to investigate whether fatigue is associated with pain in IBD after adjusting for the relevant covariates.

METHODS

Participants were recruited from nine hospitals in the south-eastern and western part of Norway. Socio-demographic variables were self-reported by patients. Disease activity was assessed by disease activity indices and faecal calprotectin. Patient-reported outcomes (PROs) were collected using the Fatigue Questionnaire (FQ), Brief Pain Inventory (BPI), Hospital Anxiety and Depression Scale (HADS) and Basic Nordic Sleep Questionnaire.

RESULTS

From a total of 452 invited patients, 414 (91.6%) provided written informed consent. After excluding any missing data, 408 total patients were included in the analyses (ulcerative colitis = 180 and Crohn's disease = 228). In the crude analysis, substantial and chronic fatigue were associated with increased pain intensity regardless of the diagnosis. However, when controlling for relevant covariates in the ANCOVA, the differences in pain intensity among patients with and without substantial or chronic fatigue were insignificant. The Cohen's d effect size was small to moderate (>0.20) in patients with chronic fatigue.

CONCLUSIONS

Despite a tendency of elevated pain intensity scores among patients with fatigue, these differences were insignificant after controlling for the relevant covariates. However, based on Cohen's effect size, these differences may be of clinical importance in a subset of patients.

Conventional treatment regimens for ulcerative colitis alleviate fatigue - an observational cohort study

OBJECTIVE

The aim of the study was to investigate the course of fatigue in a conventional inflammatory bowel disease treatment setting.

MATERIALS AND METHODS

Eighty-two patients with newly diagnosed ulcerative colitis were included in an observational cohort study and received conventional non-biological drug treatment for 3 months. Colonoscopy was performed at diagnosis and after 3 months, disease activity was assessed by Mayo score and measurements of serum C-reactive protein (CRP) and fecal calprotectin levels. Fatigue was evaluated using the fatigue visual analog scale (fVAS). Mood was assessed with the hospital anxiety and depression scale (HADS). Associations between fVAS scores and time; age; CRP, fecal calprotectin, hemoglobin, and ferritin levels; and Mayo scores, Mayo endoscopic scores, and HADS depression subscale (HADS-D) scores were explored.

RESULTS

Median fVAS scores decreased, as did Mayo scores and CRP and fecal calprotectin concentrations. HADS-D scores remained unchanged, whereas hemoglobin levels increased after 3 months. Increased fVAS scores were associated with higher ferritin, Mayo and HADS-D scores. There were no associations between fVAS scores and CRP, fecal calprotectin, or Mayo endoscopic scores. Colonic disease distribution did not influence fatigue significantly.

CONCLUSIONS

Disease activity and fatigue improved after 3 months of conventional ulcerative colitis treatment. Over time, more severe fatigue was associated with more ulcerative colitis symptoms, but not with objective disease activity markers or colonic disease distribution. A clinical setting of standard treatment regimens and medical attention may alleviate fatigue in IBD patients.

Preventive health measures in inflammatory bowel disease

We aim to review the literature and provide guidance on preventive health measures in inflammatory bowel disease (IBD). Structured searches were performed in PubMed, MEDLINE, EMBASE, Web of Science and Cochrane Library from January 1976 to June 2016 using the following keywords: (inflammatory bowel disease OR Crohn’s disease OR ulcerative colitis) AND (health maintenance OR preventive health OR health promotion). Abstracts of the articles selected from each of these multiple searches were reviewed, and those meeting the inclusion criteria (that is, providing data regarding preventive health or health maintenance in IBD patients) were recorded. Reference lists from the selected articles were manually reviewed to identify further relevant studies. Patients with IBD are at increased risk of developing adverse events related to the disease course, therapeutic interventions, or non-adherence to medication. Recent studies have suggested that IBD patients do not receive preventive services with the same thoroughness as patients with other chronic diseases. Preventive health measures can avert morbidity and improve the quality of life of patients with IBD. Gastroenterologists and primary care physicians (PCPs) should have an up to date working knowledge of preventive health measures for IBD patients. A holistic approach and better communication between gastroenterologists and PCPs with explicit clarification of roles will prevent duplication of services and streamline care.

Environmental risk factors for inflammatory bowel diseases: Evidence based literature review

AIM: Advances in genetics and immunology have contributed to the current understanding of the pathogenesis of inflammatory bowel diseases (IBD).

METHODS: The current opinion on the pathogenesis of IBD suggests that genetically susceptible individuals develop intolerance to dysregulated gut microflora (dysbiosis) and chronic inflammation develops as a result of environmental insults. Environmental exposures are innumerable with varying effects during the life course of individuals with IBD. Studying the relationship between environmental factors and IBD may provide the missing link to increasing our understanding of the etiology and increased incidence of IBD in recent years with implications for prevention, diagnosis, and treatment. Environmental factors are heterogeneous and genetic predisposition, immune dysregulation, or dysbiosis do not lead to the development of IBD in isolation.

RESULTS: Current challenges in the study of environmental factors and IBD are how to effectively translate promising results from experimental studies to humans in order to develop models that incorporate the complex interactions between the environment, genetics, immunology, and gut microbiota, and limited high quality interventional studies assessing the effect of modifying environmental factors on the natural history and patient outcomes in IBD.

CONCLUSION: This article critically reviews the current evidence on environmental risk factors for IBD and proposes directions for future research.

Targets for Health Interventions for Inflammatory Bowel Disease-fatigue

BACKGROUND AND AIMS

Fatigue is a complex, multifactorial, and multidimensional phenomenon. Recognition of modifiable correlates of fatigue can provide a further understanding of this phenomenon in patients with inflammatory bowel disease [IBD] and aid in the development of interventions tailored towards fatigue with potential for efficacy. Our aims were to systematically search and synthesise available evidence on potentially modifiable factors contributing to IBD-fatigue and what advances in the management of fatigue in individuals with IBD have been made.

METHODS

The process of selection of citations was based on an earlier review by Czuber-Dochan et al. [2013] and was undertaken in two phases: i] searching for new studies published since August 2012, using seven electronic databases; ii] re-selection of papers included in previous review according to the aims of the current review.

RESULTS

A total of 43 studies met the inclusion criteria. IBD-fatigue was consistently associated with disease activity, depression, anxiety, and sleep difficulties. However, most studies were cross-sectional; thus the direction of causation remains unknown. The relationship between biochemical factors, such as anaemia and inflammation, and fatigue was inconsistent. Solution-focused therapy, thiamine, and exercise showed promising effects on IBD-fatigue. Interventions continue to be sparse, with methodological limitations and only short-term effects reported.

CONCLUSIONS

The review identified a number of psychosocial and physical factors which could potentially be modified through targeted health interventions and improve fatigue in IBD. Research utilising prospective observational studies and randomized control trial [RCT] design is required to develop and test interventions to reduce fatigue, most likely within a biopsychosocial model of care.

Sleep Disturbance, Sleep Duration, and Inflammation: A Systematic Review and Meta-Analysis of Cohort Studies and Experimental Sleep Deprivation

BACKGROUND

Sleep disturbance is associated with inflammatory disease risk and all-cause mortality. Here, we assess global evidence linking sleep disturbance, sleep duration, and inflammation in adult humans.

METHODS

A systematic search of English language publications was performed, with inclusion of primary research articles that characterized sleep disturbance and/or sleep duration or performed experimental sleep deprivation and assessed inflammation by levels of circulating markers. Effect sizes (ES) and 95% confidence intervals (CI) were extracted and pooled using a random effect model.

RESULTS

A total of 72 studies (n > 50,000) were analyzed with assessment of C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor α (TNFα). Sleep disturbance was associated with higher levels of CRP (ES .12; 95% CI = .05-.19) and IL-6 (ES .20; 95% CI = .08-.31). Shorter sleep duration, but not the extreme of short sleep, was associated with higher levels of CRP (ES .09; 95% CI = .01-.17) but not IL-6 (ES .03; 95% CI: -.09 to .14). The extreme of long sleep duration was associated with higher levels of CRP (ES .17; 95% CI = .01-.34) and IL-6 (ES .11; 95% CI = .02-20). Neither sleep disturbances nor sleep duration was associated with TNFα. Neither experimental sleep deprivation nor sleep restriction was associated with CRP, IL-6, or TNFα. Some heterogeneity among studies was found, but there was no evidence of publication bias.

CONCLUSIONS

Sleep disturbance and long sleep duration, but not short sleep duration, are associated with increases in markers of systemic inflammation.

Physical fitness and physical activity in fatigued and non-fatigued inflammatory bowel disease patients

OBJECTIVE

To assess physical fitness and physical activity in inflammatory bowel disease (IBD) patients and whether fatigue is associated with impaired physical fitness and impaired physical activity.

MATERIALS AND METHODS

Ten patients with quiescent IBD and fatigue (fatigue group [FG]) based on the Checklist Individual Strength-Fatigue score of ≥35 were matched for age (±5 years) and sex with a non-fatigue group (NFG) with IBD. Physical fitness was measured with a cyclo-ergometric-based maximal exercise test, a submaximal 6-min walk test, and a dynamometer test to quantify the isokinetic muscle strength of the knee extensors and flexors. Level of physical activity was measured with an accelerometer-based activity monitor.

RESULTS

The patients in both groups did not differ in regard to medication use, clinical characteristics, and body composition. However, medium-to-large effect sizes for impaired physical fitness (both cardiorespiratory fitness and muscle strength) and physical activity were seen between the patients in the FG and the NFG. Especially, intensity of physical activity was significantly lower in the FG patients compared with the NFG patients (effect size: 1.02; p = 0.037). Similar results were seen when outcomes of the FG and NFG were compared with reference values of the normal population.

CONCLUSION

Fatigued IBD patients show an impaired physical fitness and physical activity compared with non-fatigued IBD patients. This gives directions for a physical component in fatigue in IBD patients. Therefore, these new insights into fatigue indicate that these patients might benefit from an exercise program to improve physical fitness and physical activity.

Circadian rhythm abnormalities - Association with the course of inflammatory bowel disease

Crohn's disease (CD) and ulcerative colitis (UC) are the main representatives of inflammatory bowel diseases (IBD), a group of chronic, immune system-mediated inflammatory diseases of the gastrointestinal (GI) tract. The pathogenesis of the intestinal lesions in IBD is not entirely identified and understood: excessive activation of the immune system may come as a result of the interaction of various environmental and infectious factors, genetic predisposition, and the mediation of abnormal intestinal flora. The main objective of the current study is to further identify the risk factors for the development of IBD. Currently, there is very little knowledge about circadian rhythm and IBD and there are only a few studies on the relationship between sleep disturbances and the course of the disease, as well as pro- and anti-inflammatory cytokine profile and general immune system functioning. Furthermore, the relationship between the expression of circadian rhythm genes and severe course of IBD is still unknown. The aim of this review is to show the current state of knowledge about the relationship between circadian rhythm disorders, sleep disturbance and inflammation in the GI tract and to analyze the possibility of employing this knowledge in diagnosis and treatment of IBD.

Cognitive Function of Patients with Crohn's Disease is Associated with Intestinal Disease Activity

BACKGROUND

Systemic inflammation and nutritional deficiencies are characteristics of Crohn's disease (CD) and have been suggested to influence cognitive performance. This study assessed cognitive function in patients with CD.

METHODS

Participants were adult patients with CD arriving at routine follow-up. Subjective cognitive complaints, depression, anxiety, fatigue, and sleep were evaluated by validated questionnaires. CD characteristics, blood tests, and Crohn's disease activity index were obtained. Nutritional risk index was derived from serum albumin and change in body weight. Montreal cognitive assessment was used for screening. Patients with either subjective cognitive complaints or Montreal cognitive assessment score ≤ 26 were tested by a computerized cognitive testing battery, with analysis of scores in 7 cognitive domains (CogDs) and an average of the CogD scores-global cognitive score (GCS). Impaired CogD was defined as scoring more than 1 SD below age and education adjusted average.

RESULTS

A total of 105 patients were recruited and 61 were tested with computerized cognitive testing battery. Mean age was 39 ± 13 and mean education years were 14 ± 2. The most commonly impaired CogDs were information processing speed (33%) and verbal function (28%). Crohn's disease activity index, nutritional risk index, and hemoglobin were significantly correlated with GCS (r = -0.34, 0.39, 0.33; P = 0.007, 0.003, 0.01). Linear regression revealed significant correlations between Crohn's disease activity index, nutritional risk index, and GCS (β = -0.3, 0.29; P = 0.03, 0.04), independent of depression. This model explained 24% of the variance in GCS.

CONCLUSIONS

Cognitive performance is related to CD activity and nutritional status. The results provide insight into potential influence of nutrition and inflammation on cognitive function. Further studies on cognitive function of patients with CD are warranted.

Toward a better understanding of the central consequences of intestinal inflammation

Inflammatory bowel diseases (IBDs), which include Crohn's disease and ulcerative colitis, are inflammatory diseases of the gastrointestinal tract. Quality of life for IBD patients is negatively affected by associated pain and gastrointestinal dysfunction, but also by serious behavioral symptoms that include depression, anxiety, fatigue, and cognitive dysfunction. Because these behavioral comorbidities are poorly understood, we have investigated them in a rat model of IBD caused by infusion of a hapten (trinitrobenzene sulfonic acid (TNBS)) into the lower colon. TNBS colitis has many similarities to Crohn's disease, and we have found that it is associated with changes in central nervous system function. TNBS-treated animals have lowered seizure thresholds, which resolve following remission, and hippocampal slices from such animals display increased excitability. There are significant changes in excitatory, AMPA receptor-mediated transmission, in part due to increased numbers of AMPA receptors lacking the GluR2 subunit. Long-term potentiation and depression are reduced in colitic animals, and the synaptic alterations are reversed if microglial activation and tumor necrosis factor α synthesis within the brain are blocked.

Practical Guideline for Fatigue Management in Inflammatory Bowel Disease

During active inflammatory bowel disease (IBD) fatigue is a common symptom, which seems related to active gut inflammation. However, even in remission many patients suffer from fatigue that negatively affects quality of life and work productivity. Currently, robust knowledge on the pathogenesis and treatment of IBD-related fatigue is lacking. In order to alleviate the burden of IBD-related fatigue, a systematic approach is mandatory. We propose a fatigue attention cycle to enhance identification, evaluation and management of fatigued IBD patients. The benefits of the cycle are twofold. Firstly, it allows the systematic and uniform identification of patients with severe fatigue, in turn allowing tailored non-pharmacological and pharmacological interventions. Secondly, uniform identification of such patients creates a well-defined patient base to investigate the underlying pathogenesis of fatigue, resulting in a greater understanding of this debilitating phenomenon and possibly resulting in the discovery of predictive factors and new treatment interventions.

Anti-fatigue effect of Myelophil in a chronic forced exercise mouse model

This study was performed to evaluate the anti-fatigue effects of Myelophil. ICR male mice (10 weeks old) were forced to run for 1 hour, 5 days/week for 4 weeks. Each running session was followed by administration of distilled water, Myelophil (50 or 100 mg/kg), or ascorbic acid (100 mg/kg) 1h later. Equal proportions of Astragali Radix and Salviae Miltiorrhizae Radix were extracted using 30% ethanol, and formulated into Myelophil. To evaluate the anti-fatigue effects of Myelophil, exercise tolerance and forced swimming tests were conducted. Underlying mechanisms, including oxidant-antioxidant balance, inflammatory response, and energy metabolism, were investigated by analyzing skeletal muscle tissues and/or sera. Myelophil significantly increased exercise ability and latency times, and decreased the number of electric shocks and immobility time on exercise tolerance and forced swimming tests compared with control group. Myelophil also significantly ameliorated fatigue-induced alterations in oxidative stress biomarkers, antioxidant enzymes and antioxidant capacity, as measured by multiple assays, including enzyme activity assays and western blotting, as well as alterations in pro- and anti-inflammatory cytokines in skeletal muscle. Furthermore, Myelophil normalized alterations in energy metabolic markers in sera. These findings suggest that Myelophil reduces the effects of chronic fatigue, likely by attenuating oxidative and inflammatory responses and normalizing energy metabolism. Consequently, this study provides evidence for the clinical relevance of Myelophil.

High C-Reactive Protein Is Associated with Poor Sleep Quality Independent of Nocturnal Symptoms in Patients with Inflammatory Bowel Disease

BACKGROUND

Sleep disruption is common in inflammatory bowel diseases (IBD). However, studies demonstrating a similar prevalence in irritable bowel syndrome suggest that nighttime disruption due to diarrhea and abdominal pain may be key drivers of poor sleep quality. Whether inflammation is associated with poor sleep independently has not been examined previously.

METHODS

This single-center study included subjects with IBD recruited to an ongoing prospective registry who completed a questionnaire assessing sleep quality and mood. Inflammatory marker levels [C-reactive protein (CRP), erythrocyte sedimentation rate] and clinical disease activity including nighttime disruption on the day of enrollment were obtained from the medical record. Logistic regression models were used to identify predictors of sleep quality.

RESULTS

The study included 131 subjects (72 women) with a median age of IBD diagnosis of 25 years. Twenty-three subjects (19 %) had a high C-reactive protein level (≥8 mg/dL). Poor sleep was more common in those with high CRP levels than with normal values (70 vs. 39 %, p = 0.009). This association remained significant on multivariate analysis [Odds ratio (OR) 4.12, 95 % confidence interval (CI) 1.38-12.29]. Adjusting for the presence of nighttime disruption did not significant alter this association (OR 3.16, 95 % CI 1.01-9.90). High CRP correlated with poor sleep even in patients not experiencing nocturnal symptoms (n = 101, OR 4.89, 95 % CI 1.24-19.36).

CONCLUSION

High CRP is associated with poor sleep quality in IBD independent of the presence of nighttime disruptions, suggesting that a relationship exists between circulating inflammatory markers and sleep.

Concerns and worries in people living with inflammatory bowel disease (IBD): A mixed methods study

OBJECTIVE

This mixed-methods study aimed to explore concerns and worries related to living with inflammatory bowel disease (IBD).

METHODS

Overall, 294 patients with a clinically established diagnosis of IBD were enrolled in this cross-sectional study. Concerns and worries were measured with one open-ended question. Measures of anxiety and depressive symptoms and disease activity were also administered. A thematic analysis was conducted and thematic map created. Spearman's rho was used to identify univariate correlations between predictors and the main themes. Binary logistic regression was used to test the predictors of the main themes.

RESULTS

Despite the majority of study participants being in IBD remission (74%, n=217), all but 11 reported significant IBD-related concerns. Twenty two percent reported symptoms of depression and 41% of anxiety. Four themes were identified: Quality of life (51%); Unpredictability (35%); Symptoms (34%) and Treatments (19%). Males and older people were less concerned about Quality of life (OR=.597, 95% CI: .363-.980 and OR=.980, 95% CI: .965-.995, respectively). Those in remission were less concerned about Symptoms (OR=.510, 95% CI: .281- .926) while those with longer disease duration worried more about the Symptoms (OR=1.035, 95% CI: 1.010-1.061). Males were less concerned about Treatments (OR=.422, 95% CI: .229-.777).

CONCLUSION

IBD patients report significant disease-related concerns even when in remission. Further exploration of what predicts patient concerns may help in shaping health-care delivery so that it better addresses patient needs.

Development of a conceptual model evaluating the humanistic and economic burden of Crohn's disease: implications for patient-reported outcomes measurement and economic evaluation

The primary objective of this review is to develop a conceptual model for Crohn's disease (CD) outlining the disease burden for patients, healthcare systems and wider society, as reported in the scientific literature. A search was conducted using MEDLINE, PsycINFO, EconLit, Health Economic Evaluation Database and Centre for Reviews and Dissemination databases. Patient-reported outcome (PRO) measures widely used in CD were reviewed according to the US FDA PRO Guidance for Industry. The resulting conceptual model highlights the characterization of CD by gastrointestinal disturbances, extra-intestinal and systemic symptoms. These symptoms impact physical functioning, ability to complete daily activities, emotional wellbeing, social functioning, sexual functioning and ability to work. Gaps in conceptual coverage and evidence of reliability and validity for some PRO measures were noted. Review findings also highlight the substantial direct and indirect costs associated with CD. Evidence from the literature confirms the substantial burden of CD to patients and wider society; however, future research is still needed to further understand burden from the perspective of patients and to accurately understand the economic burden of disease. Challenges with existing PRO measures also suggest the need for future research to refine or develop new measures.

Sleep and physical activity measured by accelerometry in Crohn's disease

BACKGROUND

Sleep and physical activity are inherent to human living, yet appear affected by Crohn's disease (CD), resulting in fatigue and disability.

AIM

To objectively assess sleep quality and physical activity and their associations using accelerometers, comparing CD vs. matched healthy control (HC) subjects.

METHODS

Exactly 49 CD and 30 HC subjects completed surveys encompassing self-reported fatigue and sleep quality, pathology testing and wore an accelerometer for 7 days, measuring physical activity and sleep. In this cross-sectional observational study, per-group comparisons were performed and in CD, factors associated with reduced activity and/or sleep quality were assessed via multivariate analyses.

RESULTS

Regarding physical activity, CD subjects overall performed less total accelerometer counts (median 1.3 × 10(6) vs. 2.0 × 10(6) ), were more sedentary (97.7% vs. 96.2%) and completed fewer bouts of moderate-vigorous intensity exercise (1.0 vs. 5.0, each P < 0.01 (Mann-Whitney) than HC over 7 days. Factors associated with poor physical activity in CD included elevated serum CRP (OR = 22.6), lower vitamin D3 (OR = 13.1) and longer disease duration (OR = 1.2 per year, each P < 0.05). Regarding sleep, the CD group had similar total sleep time (median 458 vs. 447 min, P = 0.56), but more awakenings post-sleep onset (22 vs. 11, P = 0.01). Factors associated with severe sleep dysfunction in CD included lower haemoglobin (OR = 6.7) concurrent anti-TNF (OR = 6.5, each P < 0.05) and opioid therapy (OR = 6.6, P = 0.09).

CONCLUSION

Utilising objective measurement in a habitual context over 7 days, patients with Crohn's disease exhibited poorer sleep quality and less physical activity than well-matched healthy controls.

The economic and quality-of-life burden of Crohn's disease in Europe and the United States, 2000 to 2013: a systematic review

BACKGROUND

Crohn's disease (CD) is associated with a substantial healthcare burden that affects the patient, healthcare systems and society in general.

AIM

To provide a systematic evaluation of published data relating to the economic and health-related quality-of-life (HRQoL) burden of CD in selected European countries (Germany, France, UK, Italy, Spain) and the USA since 2000.

METHODS

We undertook a systematic review of publications relating to CD, its economic burden and impact on HRQoL. Research questions focused on the disease costs from a societal perspective and HRQoL burden in adults and pediatric/adolescent patients according to disease stage/severity. Total, direct and indirect costs were identified, as well as the impact of CD on HRQoL measured using both generic and disease-specific instruments.

RESULTS

Overall, 61 publications met the research criteria (38 on costs, 23 on HRQoL). CD in the USA and Europe together was associated with annual total costs of nearly <euro>30 billion, more than half due to indirect costs. HRQoL was consistently and statistically significantly lower among CD patients compared with normal populations, due to physical, emotional and social effects.

CONCLUSIONS

CD is a global health problem with high societal costs and substantial HRQoL burden. High-value care pathways including cost-effective therapies will help to induce and maintain remission, reduce complications of disease and improve HRQoL.

Sleep disturbances and inflammatory bowel disease

With an estimated 70 million Americans suffering, sleep disorders have become a global issue, and discovering their causes and consequences are the focus of many clinical research studies. Sleep is now also considered to be an important environmental and behavioral factor associated with the process of inflammation and the immune system. Increased sleepiness is considered part of the acute phase of response to tissue injury, and sleep loss activates inflammatory cytokines such as interleukin (IL)-1 and tumor necrosis factor (TNF)-α. Clinical studies in many immune-mediated diseases, such as systemic lupus erythematosus, rheumatoid arthritis, and ankylosing spondylitis, have revealed an association of sleep disturbances with disease activity. Recent research suggests that individuals with sleep abnormalities are also at greater risk of serious adverse health, economic consequences, and most importantly increased all-cause mortality. The importance of sleep in inflammatory bowel disease has recently gained attention with some published studies demonstrating the association of sleep disturbances with disease activity, subclinical inflammation, and risk of disease relapse. A comprehensive review of sleep physiology and its association with the immune system is provided here. Experimental and clinical studies exploring this relationship in inflammatory bowel disease are reviewed, and the clinical implications of this relationship and future directions for research are also discussed.

Sequestering HMGB1 via DNA-conjugated beads ameliorates murine colitis

Inflammatory bowel disease (IBD) is chronic inflammation of the gastrointestinal tract that affects millions of people worldwide. Although the etiology of IBD is not clear, it is known that products from stressed cells and enteric microbes promote intestinal inflammation. High mobility group box 1 (HMGB1), originally identified as a nuclear DNA binding protein, is a cytokine-like protein mediator implicated in infection, sterile injury, autoimmune disease, and IBD. Elevated levels of HMGB1 have been detected in inflamed human intestinal tissues and in feces of IBD patients and mouse models of colitis. Neutralizing HMGB1 activity by administration of anti-HMGB1 antibodies or HMGB1-specific antagonist improves clinical outcomes in animal models of colitis. Since HMGB1 binds to DNA with high affinity, here we developed a novel strategy to sequester HMGB1 using DNA immobilized on sepharose beads. Screening of DNA-bead constructs revealed that B2 beads, one linear form of DNA conjugated beads, bind HMGB1 with high affinity, capture HMGB1 ex vivo from endotoxin-stimulated RAW 264.7 cell supernatant and from feces of mice with colitis. Oral administration of B2 DNA beads significantly improved body weight, reduced colon injury, and suppressed colonic and circulating cytokine levels in mice with spontaneous colitis (IL-10 knockout) and with dextran sulfate sodium-induced colitis. Thus, DNA beads reduce inflammation by sequestering HMGB1 and may have therapeutic potential for the treatment of IBD.

Evaluation of the patient-reported outcomes measurement information system in a large cohort of patients with inflammatory bowel diseases

BACKGROUND & AIMS

Patient-reported outcomes (PROs) convey important aspects of health status, complementing physician-reported measures. The PRO Measurement Information System (PROMIS) provides valid, widely available measures applicable to patients with chronic illness and the general population. We sought to evaluate these measures in a large cohort of patients with inflammatory bowel disease (IBD).

METHODS

By using data from the Crohn's and Colitis Foundation Association Partners internet cohort, we performed cross-sectional and longitudinal analyses to evaluate associations between PROMIS measures and validated disease activity indices (Short Crohn's Disease Activity Index and Simple Clinical Colitis Activity Index) and the Short IBD Questionnaire quality-of-life instrument.

RESULTS

A total of 10,634 individuals (6689 with Crohn's disease and 3945 with ulcerative colitis or indeterminate colitis) completed PRO testing. Compared with the general population (mean PROMIS score, 50), IBD patients in this cohort reported more depression (mean, 54), anxiety (mean, 52), fatigue (mean, 56), sleep disturbance (mean, 52), and pain interference (mean, 53); and they had less social satisfaction (mean, 48). In each PROMIS domain, there was worse functioning with increasing levels of disease activity and worsening Short IBD Questionnaire scores (P < .001 for all). Longitudinal analyses showed improved PROMIS scores with improved disease activity and worsening PROMIS scores with worsening disease (P < .001 for all comparisons).

CONCLUSIONS

In a cross-sectional and longitudinal study, we observed differences between patients with IBD and the general population in several important aspects of health. The improvement in diverse health outcome measures with improved disease control provides strong support for the construct validity of PROMIS measures in the IBD population. Their use should advance patient-centered outcomes research in IBD.

Fatigue management in patients with IBD: a randomised controlled trial

OBJECTIVE

To assess the effectiveness of solution-focused therapy (SFT) on fatigue and quality of life (QoL) in patients with fatigued inflammatory bowel disease (IBD).

DESIGN

Randomised controlled trial in two Dutch hospitals. Patients with IBD with quiescent IBD and with a Checklist Individual Strength--Fatigue (CIS--fatigue) score of ≥ 35 were enrolled. Patients were 1:1 randomised to receive SFT or care as usual (CAU) for 3 months. Patients were followed for a further 6 months after the SFT. Primary endpoint was defined as changes in fatigue and QoL during follow-up. Secondary endpoints included change in anxiety and depression, medication use, side effects to medication, disease activity, laboratory parameters (C-reactive protein, leucocytes and haemoglobin) and sleep quality.

RESULTS

Ninety-eight patients were included, of whom 63% were women, mean age was 40.1 years. After the SFT course, 17 (39%) patients in the SFT group had a CIS-fatigue score below 35 compared with eight (18%) of patients in the CAU group (p=0.03). The SFT group also showed a greater reduction in fatigue across the first 6 months compared with the CAU group (CIS-fatigue: p=<0.001 and CIS-total: p=0.001). SFT was associated with a significant higher mean IBD questionnaire change at 3 months (p=0.020). At 9 months, no significant differences between the two groups were observed.

CONCLUSIONS

SFT has a significant beneficial effect on the severity of fatigue and QoL in patients with quiescent IBD. However, this effect diminished during follow-up.

Fatigue is highly associated with poor health-related quality of life, disability and depression in newly-diagnosed patients with inflammatory bowel disease, independent of disease activity

BACKGROUND

Fatigue is common in Crohn's disease (CD) and ulcerative colitis (UC). Data on fatigue in newly diagnosed patients are unavailable.

AIM

To report prevalence of fatigue in newly diagnosed CD and UC patients and examine its association with health-related quality of life (HRQOL), depression and disability.

METHODS

The Ocean State Crohn's and Colitis Area Registry (OSCCAR) is a statewide cohort of newly diagnosed inflammatory bowel disease patients in Rhode Island. Fatigue was assessed using the Functional Assessment of Chronic Illness Therapy-Fatigue Scale. Patients were administered instruments measuring HRQOL, overall disability and work impairment, and depression.

RESULTS

Fatigue was prevalent in 26.4% of 220 subjects. Cohen's d effect sizes for fatigue were large: Short-Form 36 Health Survey mental health component (CD 1.5, UC 1.4) and physical health component (CD 1.4, UC 1.4), EuroQol-5D valuation of current health state (CD 1.2, UC 1.0), Inflammatory Bowel Disease Questionnaire (CD 1.9, UC 1.6) and Patient Health Questionnaire depression scale (CD 1.8, UC 1.7). Fatigued patients reported more work impairment (Score difference: CD 29.5%, UC 23.8%) and activity impairment (score difference: CD 32.3%, UC 25.7%) on the Work Productivity and Activity Impairment Questionnaire. Fatigue's association with all scores remained highly significant despite controlling for disease activity.

CONCLUSIONS

Fatigue is strongly associated with poor HRQOL, disability and depression similarly in CD and UC even when controlling for disease activity. Fatigue's association with a wide range of patient-reported outcome measures suggests that monitoring fatigue is a simple way to screen for overall disruption in patient life.

Hope and fatigue in chronic illness: The role of perceived stress

Fatigue is a debilitating symptom of chronic illness that is deleteriously affected by perceived stress, a process particularly relevant to inflammatory disease. Hopefulness, a goal-based motivational construct, may beneficially influence stress and fatigue, yet little research has examined these associations. We assessed the relation between hope and fatigue, and the mediating effect of stress, in individuals with fibromyalgia, arthritis, and inflammatory bowel disease. Covarying age, sex, and pain, stress partially mediated the association between hope and fatigue; those with greater hope reported less stress and consequent fatigue. Therapeutically, bolstering hope may allow proactive management of stressors, resulting in less fatigue.

The burden of inflammatory bowel disease: a patient-reported qualitative analysis and development of a conceptual model

BACKGROUND

The aim of this study was to describe the impacts of inflammatory bowel disease (IBD) from the patients' perspective and to inform the development of a conceptual model.

METHODS

Focus groups and one-on-one interviews were undertaken in adult patients with IBD. Transcripts from the focus groups and interviews were analyzed to identify themes and links between themes, assisted by qualitative data software MaxQDA. Themes from the qualitative research were supplemented with those reported in the literature and concepts included in IBD-specific patient-reported outcome measures.

RESULTS

Twenty-seven patients participated. Key physical symptoms included pain, bowel-related symptoms such as frequency, urgency, incontinence, diarrhea, passing blood, and systemic symptoms such as weight loss and fatigue. Participants described continuing and variable symptom experiences. IBD symptoms caused immediate disruption of activities but also had ongoing impacts on daily activities, including dietary restrictions, lifestyle changes, and maintaining close proximity to a toilet. More distal impacts included interference with work, school, parenting, social and leisure activities, relationships, and psychological well-being. The inconvenience of rectal medications, refrigerated biologics, and medication refills emerged as novel burdens not identified in existing patient-reported outcome measures.

CONCLUSIONS

IBD symptoms cause immediate disruption in activities, but patients may continue to experience some symptoms on a chronic basis. The conceptual model presented here may be useful for identifying target concepts for measurement in future studies in IBD.

Challenges in designing a national surveillance program for inflammatory bowel disease in the United States

This review describes the history of U.S. government funding for surveillance programs in inflammatory bowel diseases (IBD), provides current estimates of the incidence and prevalence of IBD in the United States, and enumerates a number of challenges faced by current and future IBD surveillance programs. A rationale for expanding the focus of IBD surveillance beyond counts of incidence and prevalence, to provide a greater understanding of the burden of IBD, disease etiology, and pathogenesis, is provided. Lessons learned from other countries are summarized, in addition to potential resources that may be used to optimize a new form of IBD surveillance in the United States. A consensus recommendation on the goals and available resources for a new model for disease surveillance are provided. This new model should focus on "surveillance of the burden of disease," including (1) natural history of disease and (2) outcomes and complications of the disease and/or treatments.

Objectively measured muscle fatigue in Crohn's disease: correlation with self-reported fatigue and associated factors for clinical application

BACKGROUND & AIMS

The association of fatigue with decreased physical performance and underlying mechanisms are poorly understood in Crohn's disease (CD). We aimed to measure and compare self-reported fatigue with skeletal muscle fatigue in CD subjects and healthy controls, and to identify associated factors that may be amenable to change.

METHODS

Demographic and clinical data were collected and fatigue assessed using the Fatigue Impact Scale (FIS) in 27 consecutive CD patients and 22 matched healthy controls. Circulating cytokines and growth factors were measured. The rate of quadriceps muscle fatigue was assessed using an isokinetic dynamometer as the decrement of force with 30 contractions performed over a 5-minute period.

RESULTS

Compared with healthy controls, CD patients reported greater levels of fatigue (mean global FIS score 45.3 vs 10.5, physical dimension score 12.3 vs 2.7 respectively; each p<0.01) and muscle fatigue (-5.2 vs -1.3 Nm min(-1); p<0.05). The two indices were correlated (r = -0.52 in CD; p<0.01). Patients with CD had lower mean serum IGF-1 levels (16.1 vs 25.4 pmol/L, p<0.01) and higher oxidative stress (TBARS assay 4.3 vs 3.9 μM, p<0.05). On multivariate analysis, low serum vitamin D, IGF-1 and magnesium, and higher IL-6 levels were associated with increased muscle fatigue (all p ≤ 0.05).

CONCLUSION

Subjects with CD had more muscle fatigue than matched healthy controls and this correlated well with self-reported fatigue. Of circulating factors that were independently associated with increased muscle fatigue, vitamin D, magnesium and IGF-1 could be targeted in future studies to reduce fatigue and improve physical performance.

Sense of coherence in patients with inflammatory bowel disease

Background and Aim. Sense of coherence (SOC) is a health-promoting concept reflecting a person's view of life and response to stressful situations and may be of importance in coping with chronic illness. The aim of this study was to explore associations between SOC and sociodemographic, disease-related, and personal characteristics in a sample of patients with inflammatory bowel disease (IBD). Methods. Measures included sociodemographic and disease-related data, the Sense of Coherence Scale, General Self-Efficacy Scale (GSE), and Fatigue Severity Scale (FSS-5). Results. In total, 428 IBD patients had evaluable questionnaires (response rate 93%). The overall mean SOC total score was 66.25 (SD 11.47) and with no statistically significant difference between patients with ulcerative colitis (UC) and patients with Crohn's disease (CD). In the multivariate analyses, higher GSE scores were significantly associated with higher SOC scores and higher FSS-5 scores were significantly associated with lower SOC scores in both UC and CD. Conclusion. GSE and FSS-5 contributed more to the variance in SOC than sociodemographic and disease-related variables. Longitudinal studies are warranted to investigate the value of SOC as a predictor of disability, medication adherence, coping behavior, and health-related quality of life.

Factors associated with physical and cognitive fatigue in patients with Crohn's disease: a cross-sectional and longitudinal study

BACKGROUND

Fatigue commonly impairs quality of life in patients with Crohn's disease (CD). This study aimed to evaluate the prevalence and severity of fatigue in CD (compared with ulcerative colitis [UC] and healthy controls) and to identify potentially modifiable factors associated with global, physical, and cognitive dimensions of fatigue.

METHODS

Clinic attendees with confirmed CD or UC and healthy volunteers were surveyed on fatigue (Fatigue Impact Scale, FIS), psychological comorbidity, sleep quality, medication, and other clinical information. A CD subgroup also completed a similar follow-up survey.

RESULTS

In 379 responders (181 CD, 113 UC, and 85 controls), global, physical, and cognitive FIS scores were highest in CD followed by UC and controls (P < 0.01), with a prevalence of global fatigue (total FIS ≥ 40) in 57% of CD patients. On multivariate analysis, concurrently active disease, poor sleep quality, and mental illness were significantly associated with all the 3 fatigue dimensions: regular vitamin B group supplementation was inversely associated with physical fatigue in the CD cohort and those of older age or with previous resection(s) (P = 0.05) were independently associated with cognitive fatigue only. Longitudinally in CD, fatigue scores remained constant between original and follow-up surveys (mean change in total FIS score +0.9; 95% confidence interval, -4.6 to 6.3). Factors independently associated with improved physical fatigue between surveys included avoidance of corticosteroids and establishment of regular exercise and with improved cognitive fatigue included cessation of immunomodulator therapy.

CONCLUSIONS

Fatigue is highly prevalent and more severe in CD. Anticipated and novel associations with improvement of physical and/or cognitive fatigue were identified, offering clues to potential therapeutic approaches to ameliorating fatigue for clinical evaluation.

Impaired sleep quality in Crohn's disease depends on disease activity

BACKGROUND

Little is known concerning the relationship of disease activity and sleep disturbances in inflammatory bowel disease (IBD) and specifically in patients with Crohn's disease.

AIM

This study examined the prevalence of poor sleep quality in patients with active and inactive Crohn's disease compared with healthy controls.

METHODS

Participants included 108 patients with Crohn's disease attending the IBD clinic of a tertiary medical center in 2009-2010 and 36 healthy volunteers. All prospectively completed a demographic questionnaire and the Pittsburgh sleep quality index (PSQI). Patients with Crohn's disease completed the Crohn's disease activity index (CDAI) and were divided into two groups accordingly: inactive disease (CDAI ≤150) and active disease (CDAI >150). Data on disease duration, medications, complications, and treatment were collected from the medical files.

RESULTS

Seventy-one patients had inactive Crohn's disease and 37 had active disease. All three groups were similar in mean age, sex distribution, and body mass index. Mean duration of Crohn's disease was 10.22 ± 8.6 years; 40 patients (37 %) had ileal disease, 16 (15 %) colonic disease, and 56 (50 %) ileo-colonic disease. Patients with active disease had a significantly higher mean ± SD global score on the PSQI (8.6 ± 2.4; indicating poorer sleep quality) than patients with inactive disease (4.6 ± 1.9) or control subjects (5.1 ± 1.7) (p < 0.0001 for both), with no significant difference between the inactive-disease and control groups. The correlation between the CDAI and PSQI scores was statistically significant (p < 0.001).

CONCLUSIONS

Impaired sleep quality is associated with active Crohn's disease, but not inactive disease.

P-selectin-mediated monocyte-cerebral endothelium adhesive interactions link peripheral organ inflammation to sickness behaviors

Sickness behaviors, such as fatigue, mood alterations, and cognitive dysfunction, which result from changes in central neurotransmission, are prevalent in systemic inflammatory diseases and greatly impact patient quality of life. Although, microglia (resident cerebral immune cells) and cytokines (e.g., TNFα) are associated with changes in central neurotransmission, the link between peripheral organ inflammation, circulating cytokine signaling, and microglial activation remains poorly understood. Here we demonstrate, using cerebral intravital microscopy, that in response to liver inflammation, there is increased monocyte specific rolling and adhesion along cerebral endothelial cells (CECs). Peripheral TNFα-TNFR1 signaling and the adhesion molecule P-selectin are central mediators of these monocyte-CEC adhesive interactions which were found to be closely associated with microglial activation, decreased central neural excitability and sickness behavior development. Similar monocyte-CEC adhesive interactions were also observed in another mouse model of peripheral organ inflammation (i.e., 2,4-dinitrobenzene sulfonic acid-induced colitis). Our observations provide a clear link between peripheral organ inflammation and cerebral changes that impact behavior, which can potentially allow for novel therapeutic interventions in patients with systemic inflammatory diseases.

The burden of comedication among patients with inflammatory bowel disease

BACKGROUND

Polypharmacy is of growing concern in the chronically ill, including individuals with inflammatory bowel disease (IBD). The authors aimed to describe the prevalence and predictors of non-IBD medication use and to compare drug use among individuals with and without IBD.

METHODS

This cross-sectional study included members of health plans included in the Thomson Reuters MarketScan databases with continuous enrollment during 2009 and 2010. Patients with IBD were identified through diagnosis codes and IBD medication dispensings and matched to 5 individuals without IBD. The prevalences of dispensed prescriptions for analgesics (narcotics, nonnarcotics), psychiatric medications (anxiolytics/sedatives/hypnotics, antidepressants), and broad drug classes defined by the Anatomic Therapeutic Classification system were estimated. Predictors of non-IBD medication use and comparisons of drug use by IBD status were evaluated using logistic regression.

RESULTS

The prevalence of medication use was higher among patients with IBD than matched members of the general population for nearly every drug class examined, including narcotic analgesics (48.1% versus 34.1%), nonnarcotic analgesics (12.8% versus 8.1%), anxiolytics/sedatives/hypnotics (25.8% versus 16.7%), and antidepressants (28.3% versus 19.4%). Medicaid insurance, middle age, gastrointestinal surgery, Crohn's disease, and increasing number of inpatient, and outpatient, and prescription events were significantly associated with analgesic and psychiatric medication use among patients with IBD. Psychiatric drug dispensings were more common among female IBD patients than male patients.

CONCLUSIONS

Patients with IBD have increased medication use, particularly of analgesic and psychiatric drugs. IBD care providers should be aware of polypharmacy and its potential for drug interactions.

Fatigue severity and factors associated with high fatigue levels in Korean patients with inflammatory bowel disease

Background/Aims

Many patients with inflammatory bowel disease (IBD) often complain of fatigue. To date, only a few studies in Western countries have focused on fatigue related to IBD, and fatigue has never been specifically studied in Asian IBD patients. The aim of the present study was to investigate the fatigue level and fatigue-related factors among Korean IBD patients.

Methods

Patients in remission or with mild to moderate IBD were included. Fatigue was assessed using the Functional Assessment of Chronic Illness Therapy-Fatigue and the Brief Fatigue Inventory. Corresponding healthy controls (HCs) also completed both fatigue questionnaires.

Results

Sixty patients with Crohn disease and 68 patients with ulcerative colitis (UC) were eligible for analysis. The comparison group consisted of 92 HCs. Compared with the HCs, both IBD groups were associated with greater levels of fatigue (p<0.001). Factors influencing the fatigue score in UC patients included anemia and a high erythrocyte sedimentation rate (ESR).

Conclusions

Greater levels of fatigue were detected in Korean IBD patients compared with HCs. Anemia and ESR were determinants of fatigue in UC patients. Physicians need to be aware of fatigue as one of the important symptoms of IBD to better understand the impact of fatigue on health-related quality of life.

Is iron deficiency in the absence of anemia associated with fatigue in inflammatory bowel disease?

OBJECTIVES

We explored whether iron deficiency in the absence of anemia is associated with fatigue in inflammatory bowel disease (IBD).

METHODS

We assessed iron deficiency and anemia in 280 participants from the population-based Manitoba IBD Cohort Study.

RESULTS

Iron deficiency was identified in 20% with Crohn's disease and 27% with ulcerative colitis. Anemia was identified overall in 50 (18%), with 230 who were nonanemic. In the nonanemic subgroup, there were no significant differences between iron-deficient and -sufficient groups in mean fatigue levels or proportions with problematic fatigue. There was no unique contribution of iron deficiency to problematic fatigue after adjustment for active disease and anemia.

CONCLUSIONS

There was no evidence of an association between iron deficiency and fatigue in the absence of anemia, suggesting that iron deficiency is not a clinically relevant contributor to fatigue in IBD.

Characterization of relations among sleep, inflammation, and psychiatric dysfunction in depressed youth with Crohn disease

OBJECTIVES

Recent reports demonstrate a link between inflammatory bowel disease (IBD) and sleep disturbance. Increased psychiatric dysfunction is consistently reported in patients with IBD. Our objective is to examine relations among sleep disturbance, inflammation, and psychiatric dysfunction in a pediatric population with Crohn disease (CD) and depression.

METHODS

Pediatric patients with CD with depression (n = 96) and healthy controls (n = 19) completed measures of sleep (Pittsburgh Sleep Quality Index [PSQI]), depression, anxiety, and abdominal pain, and provided blood for inflammatory markers. CD activity was determined by the Pediatric Crohn's Disease Activity Index. Factor analysis was performed on subscales of the PSQI to derive measures of sleep disturbance. Univariate and multivariate regression analyses assessed relations between sleep disturbance, psychosocial, and biological measures of CD and psychiatric dysfunction.

RESULTS

Sleep disturbance in depressed youth with CD was significantly greater than healthy controls, and was significantly related to measures of abdominal pain, depression, and anxiety, but not biomarkers of inflammation. Factor analysis of the PSQI demonstrated a 2-factor solution. The first factor, termed "Qualitative," included Subjective Sleep Quality, Daytime Dysfunction, Sleep Disturbance, and Sleep Latency, whereas the second factor, "Quantitative," consisted of Habitual Sleep Efficiency and Sleep Duration. This factor showed a significant relation to inflammatory markers. Multivariate modeling suggested that qualitative sleep disturbance was predicted by disease activity, pain, and anxiety, whereas quantitative sleep disturbance was predicted by disease activity.

CONCLUSIONS

These results indicate that sleep disturbance in depressed youth with CD differs depending upon illness activity. Patients may require different interventions depending upon the sleep disturbance exhibited.

Changes in fatigue over 2 years are associated with activity of inflammatory bowel disease and psychological factors

BACKGROUND & AIMS

Cross-sectional studies have identified high levels of fatigue in patients with active or quiescent inflammatory bowel disease (IBD), but there has been little attention to the long-term effects of fatigue in these patients. We performed a longitudinal study of fatigue in patients with IBD to determine its course and contributing factors.

METHODS

Data were obtained from participants in the Manitoba IBD Cohort Study (N = 312; 51% with Crohn's disease), a longitudinal population-based study. Symptomatic disease activity was measured every 6 months for 2 years to characterize long-term disease patterns as active, fluctuating, or inactive, based on the validated Manitoba IBD Index. We collected data concurrently on fatigue (Multidimensional Fatigue Inventory), psychological function, and laboratory biomarkers at the point of study entry and 1 and 2 years later.

RESULTS

Of the study participants, 26% had consistently inactive, 29% had fluctuating, and 45% had consistently active disease over the 2-year time period. Mean levels of fatigue were strongly associated with disease activity; participants with consistently inactive disease had the lowest level of fatigue at each time point. Multivariate analyses indicated fatigue levels increased over time regardless of disease pattern (P < .001). Adjusting for disease activity, disease type and age, sex (female; P < .001), and psychological variables of distress (P < .001), reduced psychological well-being (P = .002) and poor sleep quality (P < .001) were associated independently with increases in fatigue over time.

CONCLUSIONS

Fatigue can increase over time in patients with IBD, even when their disease is in remission. Psychological factors are useful targets for intervention to reduce fatigue.

Chronic rhinosinusitis and sleep: a contemporary review

BACKGROUND

Patients with chronic rhinosinusitis (CRS) exhibit centrally mediated behavioral changes commonly referred to as "sickness behavior." Sleep alteration is a component of sickness behavior which is estimated to affect up to 70 million patients annually. Patients with CRS have poor sleep quality, and little is known about the underlying etiology and pathophysiology. This narrative review aims to further organize and present the current knowledge associating sleep and CRS.

METHODS

A literature search was conducted of the OVID MEDLINE database using key search words including: "chronic rhinosinusitis," "sleep," "sleep disorders," and "sleep dysfunction." Additional keywords "nasal obstruction," "nasal polyp," and "fatigue" were identified and used to further delineate relevant articles.

RESULTS

The articles that specifically addressed sleep and CRS were dissected and presented as follows: (1) chronic rhinosinusitis and sleep; (2) chronic rhinosinusitis and fatigue; (3) chronic rhinosinusitis, nasal obstruction, and sleep; and (4) pathophysiology of sleep in chronic rhinosinusitis (cytokines in both sleep and chronic rhinosinusitis and their association to the neuroimmune biology of chronic rhinosinusitis).

CONCLUSION

Patients with CRS have sleep dysfunction that is associated with their disease severity and overall quality of life. The etiology of sleep dysfunction in CRS is most likely multifactorial. Increasing evidence suggests sleep dysfunction in patients with CRS is partly due to the inflammatory disease process, and sleep physiology in patients with CRS may be actively regulated by the inflammatory component of the disease.

Fatigue interference with daily living among patients with inflammatory bowel disease

PURPOSE

The purpose of the study was to examine fatigue interference with daily living in patients with inflammatory bowel disease (IBD) and to explore relationships between severe fatigue interference and socio-demographic and clinical variables, including use of complementary and alternative medicine (CAM).

METHODS

Data were collected using self-report questionnaires from adult IBD outpatients. Fatigue interference was assessed with the 5-item Fatigue Severity Scale, and scores ≥ 5 were defined as severe fatigue interference. CAM use was assessed with the International CAM Questionnaire. Multivariate logistic regression analysis was used to examine associations between severe fatigue interference and socio-demographic factors, clinical factors, and CAM use.

RESULTS

In total, 428 patients had evaluable questionnaires (response rate 93 %). Severe fatigue interference was reported by 39 % of the total sample. Patients with Crohn's disease (CD) (n = 238) were more likely than patients with ulcerative colitis (UC) (n = 190) to report severe fatigue interference (43 and 33 %, respectively, p = 0.003). In addition, patients reporting severe fatigue interference were more likely to have active disease than patients without severe fatigue interference (p < 0.001 for both diagnoses). Patients with inactive disease had scores comparable to the general population. Factors independently associated with severe fatigue interference in UC included disease activity and CAM use, while in CD they included disease activity and current smoking.

CONCLUSIONS

Severe fatigue interference is common among IBD patients with active disease. Among patients with UC, but not CD, CAM use was associated with severe fatigue interference. The relationship between fatigue interference and personal factors should be considered further in subsequent studies.

Sleep disturbance and risk of active disease in patients with Crohn's disease and ulcerative colitis

BACKGROUND & AIMS

Impairment of sleep quality is common in patients with inflammatory bowel diseases (IBDs) (eg, Crohn's disease [CD] and ulcerative colitis [UC]), even during clinical remission. Sleep impairment can activate inflammatory pathways. Few prospective studies have examined the role of sleep disturbance on risk of relapse in IBD.

METHODS

We analyzed data from 3173 patients with IBD (1798 in clinical remission at baseline) participating in the Crohn's and Colitis Foundation of America Partners study, a longitudinal, Internet-based cohort. Sleep disturbance was measured using a subset of questions from the Patient Reported Outcomes Measurement Information Systems sleep disturbance questionnaire. Disease activity was assessed using the short Crohn's Disease Activity Index and the simple clinical colitis activity index for CD and UC, respectively. Logistic regression was used to identify predictors of sleep quality and examine the effect of sleep quality at baseline among patients in remission on risk of active disease at 6 months.

RESULTS

Disease activity, depression, female sex, smoking, and use of corticosteroids or narcotics were associated with sleep disturbance at enrollment. Among 1291 patients whose CD was in remission at baseline, those with impaired sleep had a 2-fold increase in risk of active disease at 6 months (adjusted odds ratio, 2.00; 95% confidence interval, 1.45-2.76); however, no effect was observed in patients with UC (odds ratio, 1.14; 95% confidence interval, 0.75-1.74). These findings persisted in a number of sensitivity analyses.

CONCLUSIONS

Sleep disturbance was associated with an increased risk of disease flares in CD but not UC. These findings indicate that the evaluation and treatment of sleep disturbance in patients with CD might improve outcomes.

Sexual function and patients' perceptions in inflammatory bowel disease: a case-control survey

BACKGROUND

Sexuality is important when assessing quality of life (QoL), which is often disturbed in inflammatory bowel disease (IBD). However, sexuality is not addressed in most QoL questionnaires.

AIMS

To evaluate the prevalence and predisposing factors of sexual dysfunction among IBD patients, and their own perception.

METHODS

A postal survey was conducted in IBD patients 25-65 years of age from two tertiary centres. Patients were asked to provide a control of the same gender and age without IBD. The questionnaire assessed patient perception of the impact of IBD on their sexuality, and also allowed calculation of the Erectile Function International Index or the Female Sexual Function Index.

RESULTS

A total of 355 patients and 200 controls were available for the final analysis. Both groups were comparable except for a higher proportion of individuals who had been treated for depression among patients. Half of the female and one-third of the male patients considered that both sexual desire and satisfaction worsened after IBD diagnosis. As compared to controls, both men and women with IBD showed significantly lower scores in sexual function indexes, but a higher prevalence of sexual dysfunction was only noticed among women. Independent predictors of sexual dysfunction among IBD patients were the use of corticosteroids in women, and the use of biological agents, depression and diabetes in men.

CONCLUSIONS

Sexuality is often disturbed in IBD patients, particularly among women. Many factors seem to contribute to worsened intimacy. Sexuality should be considered when QoL is assessed in these patients.

Red flags in children with chronic abdominal pain and Crohn's disease-a single center experience

OBJECTIVE

To compare history and symptoms at initial presentation of patients with chronic abdominal pain (CAP) and Crohn's disease (CD). Red flags are used to help determine which patients with CAP are likely to have an underlying disease such as CD. However, red flags have not been validated and pediatric studies are lacking.

STUDY DESIGN

Patients seen in the outpatient Pediatric Gastroenterology Clinic at Children's Hospital of Wisconsin between 2005 and 2008 prospectively completed a demographic, history, and symptom questionnaire. Patients with abdominal pain for at least 1 month and no evidence of organic disease were compared with patients diagnosed with CD confirmed by mucosal biopsies.

RESULTS

Data were collected on 606 patients (128 with CD and 478 with functional gastrointestinal disorders). Patients with functional gastrointestinal disorders had more stressors (P < .001), were more likely to have a positive family history of irritable bowel syndrome, reflux, or constipation (P < .05), were more likely to have vomiting but less likely to have hematochezia, weight loss, and problems gaining weight (P < .05); wake from sleep and joint pain were no different between groups. Anemia, hematochezia, and weight loss were most predictive of CD (cumulative sensitivity of 94%).

CONCLUSION

The presence of anemia, hematochezia, and weight loss help identify patients with CAP who require further work-up and referral to a pediatric gastroenterologist. Furthermore, waking from sleep or joint pain occurred similarly between groups and should not be considered as "red flags."

Review article: Description and management of fatigue in inflammatory bowel disease

BACKGROUND

Fatigue is a common and leading concern for patients with inflammatory bowel disease (IBD). It is managed inadequately in IBD, and there is little evidence to support interventions.

AIM

To examine patients' experience of and factors contributing to IBD-fatigue, and to appraise its management by patients and healthcare professionals.

METHODS

Seven electronic databases were searched. Subject headings and free-text searching were used, with no time limit set. Reference lists of retrieved papers were searched manually.

RESULTS

Twenty-eight papers were reviewed. Researchers used terms including 'fatigue', 'low energy', 'tiredness', 'decline in vitality and vigour' and 'reduced energy and vitality'. Different definitions were used to conceptualise fatigue. None of the reviewed studies asked patients to describe the experience of fatigue in their own words. Numerous physical, psychological and situational factors associated with fatigue were identified. Three small randomised control trials reported a favourable effect of infliximab and adalimumab on fatigue. One intervention study reported benefit from a stress management programme and one from solution-focused therapy.

CONCLUSIONS

Inconsistent use of terminology, lack of data from patients' perspective on inflammatory bowel disease-fatigue and lack of evidence to support its management contribute to fatigue being largely ignored or overlooked by healthcare professionals. Future research should explore the experience of IBD-fatigue from the individual patient perspective. Further studies are required to fully explore the factors associated with fatigue and to develop patient-centred interventions to reduce fatigue.
