Impact of depressive mood on relapse in patients with inflammatory bowel disease: a prospective 18-month follow-up study

The Efficacy of Flupentixol-Melitracen in the Adjuvant Therapy of Ulcerative Colitis in the Chinese Population: A Meta-Analysis

Objectives

Our aim of this study is to compare the efficacy of flupentixol-melitracen in the adjuvant therapy of ulcerative colitis patients in the Chinese population.

Methods

Both the RevMan 5.2 and the Stata 12.0 software are used in this study for analysis, and a fixed-effect model (the Mantel-Haenszel method) or a random-effect model (the DerSimonian and Laird method) is used to merge or aggregate the risk ratio (RR) and its 95% confidence intervals (CI) of included studies.

Results

Eleven trials involving 654 ulcerative colitis patients (treated group: 328; control group: 326) were analyzed in this study. Significant differences (RR = 1.29, 95% CI = 1.20 to 1.40, P < 0.001) between patients were observed between the two groups.

Conclusions

Our results suggested that the efficacy of flupentixol-melitracen in the adjuvant therapy of ulcerative colitis is better than traditional drug treatments.

Electroacupuncture and Moxibustion Improved Anxiety Behavior in DSS-Induced Colitis Mice

Background and Aims

Psychological disorders are prevalent in patients with inflammatory bowel disease, but the underlying mechanisms remain unknown. The aim of this study was to study whether electroacupuncture (EA) and moxibustion (MB) can improve anxiety behavior in DSS-induced colitis mice and to investigate whether this effect is related to hypothalamic-pituitary-adrenocortical (HPA) axis.

Methods

The colitis model was established by drinking 2.5% dextran sodium sulfate (DSS). DSS-induced colitis mice were treated by EA or MB. Disease activity index (DAI) was scored; intestinal morphological and pathological structure was observed; anxiety behavior was tested by the elevated plus maze and open field. The concentration of corticotropin-releasing hormone (CRH) and cortisol (CORT) in serum was measured by enzyme-linked immunosorbent assay (ELISA). The protein expression of CRH in the colon and hypothalamus was detected by Western blot (WB).

Results

Both EA and MB treatments can improvethe morphology of their distal colonic mucosal epithelia, as well as the disease activity index. Meanwhile, anxiety behavior in colitis mice was improved slightly after EA and MB treatment. In addition, the levels of CRH and CORT in the serum were slightly improved after EA and MB treatment. These effects are further supported by WB results. The expression of CRH in the colon and hypothalamus was increased significantly after treatment, compared with the model group.

Conclusion

EA and MB were able to regulate the concentration of CRH in serum and protein expression in the peripheral and central at different levels and promote the recovery of the HPA axis that may be the basis for EA and MB to improve colonic pathology and alleviate anxiety behavior in DSS-induced colitis.

Increased Burden of Psychiatric Disorders in Inflammatory Bowel Disease

BACKGROUND

Psychiatric comorbidity in inflammatory bowel disease (IBD) is well known; however, data from a truly representative sample are sparse. We aimed to estimate the incidence and prevalence of psychiatric disorders in an IBD cohort compared with a matched cohort without IBD.

METHODS

Using population-based administrative health data from Manitoba, Canada, we identified all persons with incident IBD from 1989 to 2012 and a general population matched cohort (5:1). We applied validated algorithms for IBD, depression, anxiety disorders, bipolar disorder, and schizophrenia to determine the annual incidence of these conditions post-IBD diagnosis and their lifetime and current prevalence.

RESULTS

There were 6119 incident cases of IBD and 30,573 matched individuals. After adjustment for age, sex, socioeconomic status, region of residence, and year, there was a higher incidence in the IBD cohort compared with controls for depression (incidence rate ratio [IRR], 1.58; 95% confidence interval [CI], 1.41-1.76), anxiety disorder (IRR, 1.39; 95% CI, 1.26-1.53), bipolar disorder (IRR, 1.82; 95% CI, 1.44-2.30), and schizophrenia (IRR, 1.64; 95% CI, 0.95-2.84). Incidence rate ratios were similar for Crohn's disease and ulcerative colitis between males and females and were stable over time. However, within the IBD cohort, the incidence rates of depression, anxiety, and bipolar disorders were higher among females, those aged 18-24 years vs those older than 44 years, urbanites, and those of lower socioeconomic status. The lifetime and current prevalence rates of psychiatric disorders were also higher in the IBD than the matched cohort.

CONCLUSIONS

The incidence and prevalence of psychiatric disorders are elevated in the IBD population.

Peripheral Biomarkers of Inflammation in Depression: Evidence from Animal Models and Clinical Studies

Depression is a highly prevalent psychiatric condition, with over 300 million sufferers, and is an important comorbidity for other conditions, like cardiovascular disorders or diabetes. Therapy is largely based on psychotherapy and/or pharmacological intervention, particularly aimed at altering neurotransmitter levels in the central nervous system, but inadequate response to treatment remains a significant clinical problem. Herein, evidence supporting a molecular link between inflammation and depression will be discussed, particularly the increased prevalence of depression in chronic inflammatory diseases and the evidence on the use of anti-inflammatory drugs to treat depression. Moreover, the potential for the levels of peripheral inflammatory molecules to act as depression biomarkers, in the diagnosis and monitoring of depression will be examined, considering clinical- and animal model-based evidence.

Stress Triggers Flare of Inflammatory Bowel Disease in Children and Adults

Inflammatory bowel disease (IBD) is an idiopathic inflammatory disease characterized by chronic and relapsing manifestations. It is noteworthy that the prevalence of IBD is gradually increasing in both children and adults. Currently, the pathogenesis of IBD remains to be completely elucidated. IBD is believed to occur through interactions among genetics, environmental factors, and the gut microbiota. However, the relapsing and remitting course of IBD underlines the importance of other modifiers, such as psychological stress. Growing evidence from clinical and experimental studies suggests that stress acts as a promoting or relapsing factor for IBD. Importantly, recent studies have reported an increasing incidence of anxiety or depression in both children and adults with IBD. In this article, we review the mechanisms by which stress affects IBD, such as via impaired intestinal barrier function, disturbance of the gut microbiota, intestinal dysmotility, and immune and neuroendocrine dysfunction. With regard to both children and adults, we provide recent evidence to describe how stress can affect IBD at various stages. Furthermore, we emphasize the importance of mental healing and discuss the value of approaches targeting stress in clinical management to develop enhanced strategies for the prevention and treatment of IBD.

Long-term course of inflammatory bowel disease after the Great East Japan Earthquake

BACKGROUND AND AIM

This study analyzed inflammatory bowel disease activity for 2 years after the Great East Japan Earthquake.

METHODS

We compared the relapse rates of patients with ulcerative colitis or Crohn's disease 1 and 2 years after the earthquake with rates immediately after the earthquake. To evaluate continuous disease courses, we also performed multivariate time-to-event analyses from the time of the earthquake to the onset of additional treatments.

RESULTS

Of 903 patients with ulcerative colitis or Crohn's disease in our previous study, we could evaluate 2-year courses in 677 patients (394 ulcerative colitis and 283 Crohn's disease). Compared with the relapse rates of ulcerative colitis and Crohn's disease immediately after the earthquake (15.8% and 7.0%, respectively), those in the corresponding periods in 2012 (2.5% and 1.1%, respectively) and 2013 (2.3% and 2.5%, respectively) significantly decreased. There were 226 patients who required additional treatments after the earthquake. Multivariate time-to-event analyses revealed that only patients who had experienced the death of family members or friends were likely to need additional treatments (hazard ratio = 1.77, 95% confidence interval = 1.25-2.47). No other factors had a significant influence.

CONCLUSIONS

The relapse rates 1 and 2 years after the earthquake significantly decreased. The factors that influenced long-term relapse were different from those that influenced short-term relapse.

Stress burden and neuroendocrine regulation of cytokine production in patients with ulcerative colitis in remission

Stress demonstrably contributes to disease course in patients with inflammatory bowel diseases but the underlying mechanisms remain elusive. Here, we investigated if neuroendocrine regulation of pro- and anti-inflammatory cytokine production by peripheral blood immune cells is altered in patients with ulcerative colitis in remission (UCR). Using a whole blood stimulation assay, we measured the sensitivity of lipopolysaccharide (LPS)-induced TNF-α and IL-10 production to the glucocorticoid receptor agonist dexamethasone (DEX), the β₂-adrenergic receptor agonist terbutaline (TERB), and the α7-nicotinic acetylcholine receptor agonist 3-[2,4-dimethoxy-benzylidene]-anabaseine (GTS-21) in UCR patients (N = 26) and in healthy controls (HC, N = 25). Additionally, we assessed anxiety and depression symptoms as well as chronic perceived stress and disease-specific quality of life. Results showed that UCR patients exhibited greater anxiety, depression and chronic stress levels than HC, and reduced disease-specific quality of life. Plasma concentrations of TNF-α, IL-8, C-reactive protein (CRP) and lipopolysaccharide binding protein (LBP) were significantly higher, while LPS-induced IL-10 production was substantially lower in UCR compared to HC. Independent of group, DEX and GTS-21 dose-dependently inhibited TNF-α and IL-10 production, whereas TERB inhibited TNF-α and upregulated IL-10 production. However, at higher TERB doses (i.e., stress levels), upregulation of IL-10 production was significantly diminished in UCR compared to HC. Together, these findings demonstrate that downregulation of pro-inflammatory cytokine production in peripheral blood immune cells through glucocorticoid, adrenergic, and cholinergic mechanisms is essentially normal in UC in clinical remission and as efficient as in healthy individuals. However, UCR patients exhibited signs of systemic low-grade inflammation and dysregulation of anti-inflammatory IL-10 production. Impaired adrenergic upregulation of IL-10 production during remission could be one mechanism how stress facilitates relapse and conversion to symptomatic disease in these patients.

Anxiety, depression, and inflammation after restorative proctocolectomy

PURPOSE

Anxiety and depression (A&D) are more common in inflammatory bowel disease (IBD) and in IBD patients who undergo proctocolectomy with ileal pouch-anal anastomosis (IPAA). Our aim was to test the hypothesis that chronic inflammatory conditions in IPAA are associated with increased incidence of A&D.

METHODS

Retrospective cohort study at a single tertiary care referral center using a consented IBD and colon cancer natural history registry. Demographic and clinical factors, including surgical and psychiatric history, were abstracted.

RESULTS

We compared A&D rate in three cohorts: (1) ulcerative proctocolitis with IPAA (UC) (n = 353), (2) Crohn's disease/indeterminate proctocolitis with IPAA (CDIC) (n = 49), and (3) familial adenomatous polyposis with IPAA (FAP) (n = 33). Forty-six CDIC patients (93.9%) demonstrated pouch-related inflammation, while 126 UC patients (35.7%) and 2 FAP patients (6.1%) developed pouchitis. CDIC had a higher rate of A&D co-diagnosis compared to UC and FAP (20.4 vs.12.7 vs.12.1% respectively; p < 0.05). UC patients with pouchitis also exhibited a higher rate of A&D than UC without pouchitis (19.8 vs.8.8%; p < 0.05). Multivariable analysis demonstrated that pre-operative corticosteroid use (OR = 4.46, CI = 1.34-14.87, p < 0.05), female gender (OR = 2.19, CI = 1.22-3.95, p < 0.01), tobacco use (OR = 2.92, CI = 1.57 = 5.41, p < 0.001), and pouch inflammation (OR = 2.37, CI = 1.28-4.39, p < 0.05) were each independently associated with A&D in these patients.

CONCLUSIONS

Anxiety and depression were more common in patients experiencing inflammatory conditions of the pouch. UC without pouchitis and FAP patients demonstrated lower rates of A&D (that were comparable to the general population), implying that having an IPAA alone was not enough to increase risk for A&D. Factors independently associated with A&D in IPAA included an inflamed pouch, corticosteroid use, smoking, and female gender.

What Do Participants of the Crohn's and Colitis UK (CCUK) Annual York Walk Think of Their Inflammatory Bowel Disease Care? A Short Report on a Survey

There has been a growing interest in a patient-centered model of care in inflammatory bowel disease; however, no relevant study using a mixed methodology has been conducted to date. Thus, our multidisciplinary group aimed to explore the issue of patient involvement in care among the inflammatory bowel disease community. A mixed-methods anonymous survey was conducted during the Crohn's and Colitis UK annual event. Summary statistics were used to describe the sample, and a simple thematic analysis identified key themes in qualitative responses. There were 64 survey respondents, representing 73% of the total family/friend groups participating (N = 87). Overall, 75% of respondents answered that they had the opportunity to discuss their care with their inflammatory bowel disease practitioner and 81% felt their opinions were taken on board and valued. A clear majority (84%) had at some point been treated by a gastroenterologist. In contrast, less than half (44%) had the opportunity for a dietician consultation and only 28% had the opportunity for a psychologist/counselor consultation. Although satisfaction with inflammatory bowel disease care was high, access to specialty services was concerning. Efforts should be made to provide access to mental health practitioners for those with clinically significant anxiety and/or depression.

Predictors of Impaired Mental Health and Support Seeking in Adults With Inflammatory Bowel Disease: An Online Survey

This study explored the possible factors associated with psychological distress in adults with inflammatory bowel disease (IBD) and also engagement in mental health services (MHS) in those reporting distress in a large Australian cohort. Participants with IBD completed an online survey assessing perceived IBD activity (Manitoba Index; MI), mental health status (K10), demographic details, and engagement with MHS for IBD-associated issues. Of 336 participants, 76.5% perceived themselves as having active disease over the past 6 months, and on K10 scores, 51.8% had a mental health issue. Of participants with a mental health issue, only 21.3% were currently receiving mental health support. A stepwise logistic regression analysis correctly classified 78.7% of the status of receiving mental health support, with lower income (<$60,000 per annum) the only significant predictor. Paradoxically, the degree of psychological distress did not correlate with seeking mental health support. The data show that in individuals with ongoing symptoms attributed to active IBD, mental health issues are highly prevalent, with older age and higher income being additional drivers of mental health issues. The greater challenge, however, seems not to be identifying mental health issues, but in getting those in need to engage in MHS.

Illness Cognitions and Health-Related Quality of Life of Patients With Inflammatory Bowel Disease

Patients' cognitions about their disease and treatment are important mediators between health and quality of life of patients with chronic diseases and also explain the occurrence of individual differences in individuals' adjustment to chronic disease. The aim of this study was to examine the relationship between illness cognitions and health-related quality of life among adult patients with inflammatory bowel disease. Self-report data on illness cognition and health-related quality of life were collected from 118 people with Crohn disease or ulcerative colitis. Illness cognition of greater helplessness significantly predicted health-related quality of life in patients with inflammatory bowel disease. A relative contribution of acceptance and perceived benefits was not confirmed as a predictor of health-related quality of life. The other variables (type of disease, duration of disease, age, and episode of relapses) did not have statistical significance, except for gender. Results demonstrate that experiencing helplessness in relation to the disease, its treatment, and consequences can be generalized to patients in all areas of daily life, leading to deterioration in their overall psychological and physical functioning. These results can provide useful indicators of potential patient's adherence in treatment and self-management of inflammatory bowel disease.

Influences and Impact of Anxiety and Depression in the Setting of Inflammatory Bowel Disease

BACKGROUND

Individuals with inflammatory bowel disease (IBD) are at increased risk of developing anxiety or depression (A&D). Crohn's disease (CD) and ulcerative colitis (UC) with comorbid A&D are both more challenging to manage. IBD providers need to better understand the causes and impact of A&D in order to improve care for IBD patients. We sought to identify clinical factors that influence development of A&D and healthcare utilization in IBD.

METHODS

This is a retrospective analysis using an IBD natural history registry from a single tertiary care referral center. Presence of A&D was determined based upon responses to the Hospital Anxiety and Depression Scale. Demographic and clinical factors were abstracted to evaluate for significant associations.

RESULTS

Four hundred thirty-two IBD patients (132 UC, 256 CD, and 44 indeterminate colitis) were included in this study. One hundred ninety-two (44.4%) had anxiety or depression or both, and most were female (59.4%, P < 0.05). History of surgery (P < 0.05), female gender (P < 0.05), smoking (P < 0.05), and extra-intestinal manifestations (P < 0.01) were each independently predictive of A&D. Inflammatory bowel disease patients with A&D more often underwent imaging studies (53.6% vs 36.7%, P < 0.05), visited the ED (30.7% vs 20.8%, P < 0.05), or were hospitalized (31.7% vs 21.7%, P < 0.05). They were also more frequently prescribed corticosteroids (50.5% vs 36.7%, P < 0.01) and biologic medications (62.5% vs 51.3%, P < 0.05). Finally, they were more likely to have had at least 1 "no-show" (29.2% vs 16.7%, P < 0.01) and had a higher mean number of "no-shows" (0.69 +/- 0.1 vs 0.30 +/- 0.1, P < 0.01) over the study period.

DISCUSSION

Anxiety and depression are common in the setting of IBD and are strongly associated with surgical history, disease complications (including extra-intestinal manifestations), smoking, and female gender. Inflammatory bowel disease patients with A&D are also more likely to require therapy and to utilize healthcare resources. This study refines our understanding of A&D development and its impact in IBD and provides additional considerations for management in this setting.

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.

The Effect of Antidepressants on the Course of Inflammatory Bowel Disease

BACKGROUND AND AIMS

Mood may have an important role in the natural history of inflammatory bowel disease (IBD). However, the impact of antidepressant use on prognosis is unknown. We aimed to address this in a longitudinal study in a referral population.

METHODS

We collected demographic data, clinical disease activity and mood using validated questionnaires, and antidepressant use at baseline. Longitudinal disease activity was defined by disease flare or need for glucocorticosteroids, escalation of medical therapy, hospitalisation, or intestinal resection. We compared rates of these over a minimum period of 2 years according to antidepressant use at baseline.

RESULTS

In total, 331 patients provided complete data, of whom 54 (15.8%) were taking an antidepressant at study entry. Older age, female gender, and abnormal mood scores were associated with antidepressant use. During longitudinal follow-up, there was a trend towards lower rates of any of the four endpoints of IBD activity of interest in patients with abnormal anxiety scores at baseline and who were receiving an antidepressant (42.3% versus 64.6%, P = 0.05). Based on univariate Cox regression analysis, there was a trend towards lower rates of escalation of medical therapy among patients receiving antidepressants at baseline (hazard ratio (HR) = 0.59; 95% confidence interval (CI) 0.35-1.00, P = 0.05). None of the differences observed persisted after multivariate Cox regression.

CONCLUSIONS

Antidepressants may have some beneficial effects on the natural history of IBD, but larger studies with longer follow-up are required. Whether these effects are limited to patients with abnormal mood remains uncertain.

SYMPTOMS OF ANXIETY AND DEPRESSION, AND QUALITY OF LIFE OF PATIENTS WITH CROHN'S DISEASE

BACKGROUND

Crohn's disease is an idiopathic chronic inflammatory disease. It is classified as an inflammatory bowel disease. Crohn's disease can change patient quality of life, especially during flares. Crohn's disease has been associated with symptoms of anxiety and depression, because the clinical symptoms have a high impact on quality of life.

OBJECTIVE

To investigate the prevalence of symptoms of anxiety and depression in Brazilian patients diagnosed with Crohn's disease, as well as their quality of life.

METHODS

A total of 110 Brazilian patients aged 21-59 years, both genders, with Crohn's disease were included. The data were collected through questionnaires. The Hospital Anxiety and Depression Scale (HADS) was used to assess anxiety and depression symptoms. Quality of life was evaluated using the Inflammatory Bowel Disease Questionnaire. Data were analyzed by ANOVA, followed by the Duncan post-hoc test and the multiple linear regression test.

RESULTS

Of the total, 61.7% of participants reported symptoms of anxiety or depression or both. Regarding quality of life, the majority (43.6%) were classified as "regular" and the minority (3.6%) as "excellent". Multiple linear regression showed that worse quality of life correlated with greater presence of anxiety and depression symptoms (<0.001).

CONCLUSION

Crohn's disease has considerable impact on quality of life and contributes to the appearance of anxiety and/or depression symptoms.

Management of Paediatric Ulcerative Colitis, Part 1: Ambulatory Care-An Evidence-based Guideline From European Crohn's and Colitis Organization and European Society of Paediatric Gastroenterology, Hepatology and Nutrition

BACKGROUND

The contemporary management of ambulatory ulcerative colitis (UC) continues to be challenging with ∼20% of children needing a colectomy within childhood years. We thus aimed to standardize daily treatment of pediatric UC and inflammatory bowel diseases (IBD)-unclassified through detailed recommendations and practice points.

METHODS

These guidelines are a joint effort of the European Crohn's and Colitis Organization (ECCO) and the Paediatric IBD Porto group of European Society of Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN). An extensive literature search with subsequent evidence appraisal using robust methodology was performed before 2 face-to-face meetings. All 40 included recommendations and 86 practice points were endorsed by 43 experts in Paediatric IBD with at least an 88% consensus rate.

RESULTS

These guidelines discuss how to optimize the use of mesalamine (including topical), systemic and locally active steroids, thiopurines and, for more severe disease, biologics. The use of other emerging therapies and the role of surgery are also covered. Algorithms are provided to aid therapeutic decision-making based on clinical assessment and the Paediatric UC Activity Index (PUCAI). Advice on contemporary therapeutic targets incorporating the use of calprotectin and the role of therapeutic drug monitoring are presented, as well as other management considerations around pouchitis, extraintestinal manifestations, nutrition, growth, psychology, and transition. A brief section on disease classification using the PIBD-classes criteria and IBD-unclassified is also part of these guidelines.

CONCLUSIONS

These guidelines provide a guide to clinicians managing children with UC and IBD-unclassified management to provide modern management strategies while maintaining vigilance around appropriate outcomes and safety issues.

Risk of depression in patients with inflammatory bowel disease

OBJECTIVE

Depression is more prevalent in patients with inflammatory bowel disease (IBD) than in the general population. This study evaluated disease-related risk factors for depression in Crohn's disease (CD) and ulcerative colitis (UC).

METHODS

Altogether 348 patients with IBD (228 with CD, 120 with UC) were included at our Outpatient IBD Clinic. Their characteristics, laboratory results and scores of depression, quality of life and clinical disease activity were retrospectively retrieved from questionnaires and medical records. The patient health questionnaire 9 (PHQ-9) was used as an algorithm for a probable diagnosis of major depression employing a cut-off point ≥10. Logistic regression analyses were performed to identify risk factors for depression.

RESULTS

Among these patients, 163 (46.8%) had no or minimal depression (PHQ-9 score 0-4), 108 (31.0%) had mild depression (PHQ-9 score 5-9) and 77 (22.1%) were at risk of major depression (PHQ-9 score ≥10). Patients with CD had a higher risk of major depression than those with UC (25.4% vs 15.8%, P = 0.040). PHQ-9 scores correlated strongly with clinical disease activity and quality of life scores in both groups but only weakly and solely in the CD group with biochemical disease activity. Clinical disease activity was identified as the only independent risk factor for depression in CD (odds ratio 7.814, 95% CI 2.688-22.717, P < 0.001), while no independent risk factor for depression was detected in UC.

CONCLUSION

Achieving clinical remission in patients with IBD seems to be the most important factor to reduce the risk of depression.

The association of inflammatory bowel disease and immediate postoperative outcomes following lumbar fusion

BACKGROUND CONTEXT

The United States Centers for Disease Control and Prevention estimates the prevalence of inflammatory bowel disease (IBD) at more than 3.1 million people. As diagnostic techniques and treatment options for IBD improve, the prevalence of IBD is expected to increase. For spine surgeons, patients with IBD have a unique complication profile because patients with IBD may present with poor nutritional status and because the medications used to manage IBD have been associated with poor vertebral bone mineralization and immunosuppression. Presently, there are very limited data regarding perioperative outcomes among patients with IBD who undergo spinal surgery. The present study begins to address this knowledge gap by describing trends in patients with IBD undergoing lumbar fusion and by quantifying the association between IBD and immediate postoperative outcomes using a large, national database.

PURPOSE

To advance our understanding of the potential pitfalls and risks associated with lumbar fusion surgery in patients with IBD.

DESIGN/SETTING

Retrospective cross-sectional analysis.

PATIENT SAMPLE

The Nationwide Inpatient Sample (NIS) database was queried from 1998 to 2011 to identify adult patients (18+) who underwent primary lumbar fusion operations using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) coding.

OUTCOME MEASURES

Incidence of lumbar fusion procedures, prevalence of IBD, complication rates, length of stay, and total hospital charges.

METHODS

The annual number of primary lumbar fusion operations performed between 1998 and 2011 was obtained from the NIS database. Patients younger than 18 years of age were excluded. The prevalence of IBD in this population (both Crohn disease and ulcerative colitis) was determined using ICD-9-CM codes. Logistic regression models were estimated to determine the association between IBD and the odds of postoperative medical and surgical complications, while controlling for patient demographics, comorbidity burden, and hospital characteristics. The complex survey design of the NIS was taken into account by clustering on hospitals and assuming an exchangeable working correlation using the discharge weights supplied by the NIS. We accounted for multiple comparisons using the Bonferroni correction and an alpha level for statistical significance of . 0028.

RESULTS

The prevalence of IBD is increasing among patients undergoing lumbar fusion, from 0.21% of all patients undergoing lumbar fusion in 1998 to 0.48% of all patients undergoing lumbar fusion in 2011 (p<.001). The odds of experiencing a postoperative medical or surgical complication were not significantly different when comparing patients with IBD with control patients without IBD after controlling for patient demographics, comorbidity burden, and hospital characteristics (adjusted odds ratio=1.1, 95% confidence interval [CI] 0.99-1.3, p=.08). On multivariable analysis, the presence of IBD in patients undergoing lumbar fusion surgery was associated with longer length of stay and greater hospitalization charges.

CONCLUSIONS

Among patients who underwent lumbar fusion, IBD is a rare comorbidity that is becoming increasingly more common. Importantly, patients with IBD were not at increased risk of postoperative complications. Spine surgeons should be prepared to treat more patients with IBD and should incorporate the present findings into preoperative risk counseling and patient selection.

Tryptophan Metabolism through the Kynurenine Pathway is Associated with Endoscopic Inflammation in Ulcerative Colitis

BACKGROUND AND AIMS

Mucosal appearance on endoscopy is an important indicator of inflammatory burden and determines prognosis in ulcerative colitis (UC). Inflammation induces tryptophan metabolism along the kynurenine pathway (KP) and yields immunologically relevant metabolites. We sought to examine whether changes in serum tryptophan metabolites and tissue expression of KP enzymes are associated with UC endoscopic and histologic disease severity.

METHODS

Serum and mucosal samples were prospectively obtained at colonoscopy in patients with UC. Mayo disease activity scores, demographics, smoking status, medications, and outcomes were collected. Serum tryptophan metabolites were analyzed using ultra-high performance liquid chromatography (uHPLC), and gas chromatography-mass spectrometry (GC-MS), and enzyme expression was determined by quantitative real-time polymerase chain reaction. Metabolite and enzyme levels were compared by endoscopic subscore, clinical disease activity, time to surgery, and hospitalization.

RESULTS

This study included 99 patients with Mayo endoscopic subscores 0-3. Kynurenic acid/tryptophan ratio (KYNA/T) and expression of indolamine 2,3-dioxygenase 1 (IDO1), tryptophan 2,3-dioxygenase, kynurinase, and kynurenine monooxygenase correlated positively with endoscopic subscore. Adjusting for age of diagnosis, smoking status, disease extent, and medications yielded significant odds of endoscopic inflammation with increasing KYNA/T (OR 1.0015, P = 0.0186) and IDO1 expression (OR 1.0635, P = 0.0215). The highest tertile ratio of KYNA/T had shorter time to surgery (P = 0.009) and hospitalization (P = 0.01) than the lowest.

CONCLUSIONS

Increasing KYNA/T is closely associated with endoscopic inflammation and predictive of disease outcomes in patients with UC. These findings identify this novel metabolic association and further support the role of the KP in regulating mucosal inflammation in UC. 10.1093/ibd/izy103_video1izy103.video15788135676001.

Bi-directionality of Brain-Gut Interactions in Patients With Inflammatory Bowel Disease

BACKGROUND & AIMS

Inflammatory bowel diseases (IBD) are associated with mood disorders, such as anxiety or depression, but it is not clear whether one contributes to development of the other, or if the interaction is bi-directional (anxiety or depression contributes to the progression of IBD, and IBD affects psychological health). We performed a 2-year longitudinal prospective study of patients in secondary to care investigate the bi-directionality of IBD and mood disorders.

METHODS

We collected data from 405 adult patients with a diagnosis of Crohn's disease (CD) or ulcerative colitis (UC) from November 2012 through June 2017. Demographic features, subtypes of IBD, treatments, symptoms, somatization, and fecal level of calprotectin were recorded at baseline. IBD activity was determined at baseline and after the follow-up period (2 years or more) using the Harvey-Bradshaw Index for CD and the Simple Clinical Colitis Activity Index for UC (scores ≥5 used to define disease activity). Anxiety and depression data were collected using the Hospital Anxiety and Depression Scale (HADS), at baseline and after the follow-up period. Objective markers of disease activity, including glucocorticosteroid prescription or flare of disease activity, escalation of therapy, hospitalization secondary to IBD activity, and intestinal resection during follow-up were assessed via case note review. A brain-gut direction of disease activity was defined as development of new IBD activity in patients with quiescent IBD and abnormal HADS scores at baseline. A gut-brain direction of disease activity was defined by subsequent development of abnormal HADS scores in patients with active IBD and normal HADS scores at baseline. We performed multivariate Cox regression controlling for patient characteristics and follow-up duration.

RESULTS

Baseline CD or UC disease activity were associated with an almost 6-fold increase in risk for a later abnormal anxiety score (hazard ratio [HR], 5.77; 95% CI, 1.89-17.7). In patients with quiescent IBD at baseline, baseline abnormal anxiety scores were associated with later need for glucocorticosteroid prescription or flare of IBD activity (HR, 2.08; 95% CI, 1.31-3.30) and escalation of therapy (HR, 1.82; 95% CI, 1.19-2.80). These associations persisted when normal IBD activity index scores and fecal level of calprotectin <250 μg/g were used to define quiescent disease at baseline.

CONCLUSIONS

In a 2-year study of patients with CD or UC, we found evidence for bi-directional effects of IBD activity and psychological disorders. Patients with IBD should be monitored for psychological well-being.

Association of Inflammatory Bowel Disease (IBD) with Depressive Symptoms in the United States Population and Independent Predictors of Depressive Symptoms in an IBD Population: A NHANES Study

Background/Aims

There is a paucity of population-based studies on the association between inflammatory bowel disease (IBD) and depression in the U.S. population. We sought to study this association using the National Health and Nutrition Examination Survey (NHANES) database.

Methods

We used NHANES data from 2009 to 2010. Our study included 190,269,933 U.S. adults without IBD and 2,325,226 with IBD. We sought to determine whether IBD is an independent risk factor for depressive symptoms (DS) in the U.S. population and studied the independent predictors of DS in IBD population.

Results

DS was present in 49% of the IBD population versus 23% of the non-IBD population (p<0.001). During the multivariate analysis, we found that IBD was independently associated with DS in the U.S. population (p=0.002). The independent predictors of DS in the IBD population were older age (p=0.048) and divorced/separated/widowed status (p=0.005). There was nonsignificant increase in suicidal risk in IBD population with DS versus that in non-IBD population with DS (27% vs 12%, respectively, p=0.080). Only 36% of IBD individuals with DS visited mental health professional or psychiatrist within the past year.

Conclusions

IBD is independently associated with DS in the U.S. population. Further research is warranted on risk stratification, screening and management of those with IBD who are at risk of depression.

Systematic review: psychosocial factors associated with pain in inflammatory bowel disease

BACKGROUND

Pain is a frequently reported symptom of inflammatory bowel disease (IBD) experienced by patients in active disease and remission. Psychological factors play a significant role in pain, but have not been systematically reviewed in IBD.

AIM

To review psychosocial factors associated with pain in adults diagnosed with IBD.

METHODS

Electronic (PsycInfo, MEDLINE, EMBASE, Cochrane Library, CINAHL, Web of Science), and hand-searching were conducted February-May 2017. Two authors carried out screening and data extraction.

RESULTS

Fifteen studies including 5539 IBD patients were identified. Emotional, cognitive-behavioural and personality factors were associated with IBD-pain. Depression and anxiety were the most commonly explored constructs, followed by perceived stress and pain catastrophising, all of which were positively associated with greater pain. Greater abdominal pain was associated with a concurrent mood disorder over fivefold (OR 5.76, 95% CI 1.39, 23.89). Coping strategies and pain fear avoidance correlated with pain levels. Perceived social support (r = .26) and internal locus of control (r = .33) correlated with less pain. Patients reporting pain in IBD remission more frequently had an existing diagnosis of a mood disorder, a chronic pain disorder and irritable bowel syndrome. Six studies controlled for disease activity, of which 4 found that psychosocial factors significantly predicted pain. The majority of studies (n = 10) were of high quality.

CONCLUSION

Psychosocial factors appear to play a significant role in IBD-pain. Further research is required to explore psychosocial constructs in relation to IBD-pain, with use of validated pain measures, large sample sizes and clearer characterisation of disease activity.

Evaluation of Brain Activity Using Near-infrared Spectroscopy in Inflammatory Bowel Disease Patients

Depression is implicated as a risk factor for the recurrence of inflammatory bowel disease (IBD). Near-infrared spectroscopy (NIRS) and brain-derived neurotrophic factor (BDNF) are useful tools for evaluation of brain activity and a depressive state, respectively. The aim of this study was to clarify the association between brain activity or depressive symptoms and IBD using NIRS and BDNF. This study included 36 ulcerative colitis (UC) patients, 32 Crohn’s disease (CD) patients, and 17 healthy controls (HC). Center for Epidemiologic Studies Depression Scale (CES-D) scores were determined, NIRS was performed, and serum BDNF levels were measured in all subjects. NIRS showed that the mean oxygenated hemoglobin concentration was significantly lower in the frontal lobe in the UC group than in the HC group (HC 167 ± 106 vs. UC 83.1 ± 85.3, p < 0.05). No significant difference was seen between the HC and CD groups. There were also no significant differences in CED-D scores and BDNF levels among the groups. Changes in the NIRS values of the UC group may indicate decreased brain activity and a fundamental difference between UC and CD, which are often lumped together as two types of IBD.

Depression Is Associated With More Aggressive Inflammatory Bowel Disease

OBJECTIVES

Depression is prevalent in inflammatory bowel disease (IBD) patients. The impact of depression on IBD is not well-studied. It is unknown how providers should assess depression.

METHODS

We used data from the Sinai-Helmsley Alliance for Research Excellence cohort, to assess methods of diagnosing depression and effects of baseline depression on disease activity at follow-up. A patient health questionnaire (PHQ-8) score ≥5 was consistent with mild depression. Relapse was defined as a modified Harvey-Bradshaw Index ≥5 or Simple Clinical Colitis Activity Index >2. We performed binomial regression to calculate adjusted risk ratios (RRs).

RESULTS

We included 2,798 Crohn's disease (CD) patients with 22-month mean follow-up and 1,516 ulcerative colitis (UC) patients with 24-month mean follow-up. A total of 64% of CD patients and 45% of UC patients were in remission at baseline. By self-report, 20% of CD and 14% of UC patients were depressed. By PHQ-8, 38% of CD and 32% of UC patients were depressed (P<0.01). Adjusted for sex, remission, and disease activity, CD patients with baseline depression were at an increased risk for relapse (RR: 2.3; 95% confidence interval (CI): 1.9-2.8), surgery, or hospitalization (RR: 1.3 95% CI: 1.1-1.6) at follow-up. UC patients with baseline depression were also at increased risk for relapse (RR: 1.3; 95% CI: 0.9-1.7), surgery, or hospitalization (RR: 1.3; 95% CI: 1.1-1.5) at follow-up.

CONCLUSIONS

Baseline depression is associated with a higher risk for aggressive IBD at follow-up. A single question is not a sensitive method of assessing depression. Providers should consider administering the PHQ-8 to capture those at greater risk for aggressive disease.

Improvement of psychological status after infliximab treatment in patients with newly diagnosed Crohn's disease

BACKGROUND

Patients with newly diagnosed Crohn's disease (CD) are associated with impaired physical and psychological well-being. These psychological characteristics are dynamic with the course of disease and could be influenced by medical treatment. Infliximab is effective and widely used in moderate-to-severe CD patients. The aim of this study was to evaluate the improvement of psychological status after infliximab treatment in patients with newly diagnosed CD.

METHODS

Newly diagnosed moderate-to-severe CD patients were prospectively enrolled in our study. Infliximab 5 mg/kg was administered at weeks 0, 2, 6, 14, 22, and 30. Outcomes including disease severity, illness perceptions, coping strategies, anxiety, depression, and quality of life (QoL) were measured at baseline, week 14, and week 30.

RESULTS

Eighty-two patients completed our study. The rates of clinical remission at weeks 14 and 30 were 59/82 (72.0%) and 58/82 (70.7%), respectively. Patients who achieved clinical remission at weeks 14 and 30 significantly improved in illness perceptions (P<0.001 and <0.001), maladaptive coping (P=0.005 and 0.004), anxiety (P<0.001 and <0.001), depression (P=0.004 and 0.004), and QoL (P<0.001 and <0.001). However, emotion-focused coping and problem-focused coping remained unchanged. For infliximab nonresponders, no significant changes were seen in illness perceptions, coping strategies, anxiety, depression, or QoL at week 14 or 30.

CONCLUSION

Effective infliximab treatment not only led to clinical remission in patients with newly diagnosed moderate-to-severe CD but also improved their psychological status including illness perceptions, maladaptive coping, anxiety, depression, and QoL.

Recommendations of the Spanish Working Group on Crohn's Disease and Ulcerative Colitis (GETECCU) and the Association of Crohn's Disease and Ulcerative Colitis Patients (ACCU) in the management of psychological problems in Inflammatory Bowel Disease patients

AIMS

To establish recommendations for the management of psychological problems affecting patients with inflammatory bowel disease (IBD).

METHODS

A meeting of a group of IBD experts made up of doctors, psychologists, nurses and patient representatives was held. The following were presented: 1) Results of a previous focal group, 2) Results of doctor and patient surveys, 3) Results of a systematic review of tools for detecting anxiety and depression. A guided discussion was then held about the most important psychological and emotional problems associated with IBD, appropriate referral criteria and situations to be avoided. The validated instrument most applicable to clinical practice was selected. A recommendations document and a Delphi survey were designed. The survey was sent to the group and to a scientific committee of the GETECCU group in order to establish the level of agreement with these recommendations.

RESULTS

Fifteen recommendations were established linked to 3 key processes: 1) What steps should be taken to identify psychological problems at an IBD appointment; 2) What are the criteria for referring patients to a mental health specialist; 3) How to approach psychological problems.

CONCLUSIONS

Resources should be made available to healthcare professionals so that they can treat these problems during consultations, identify the disorders which could affect the clinical course of the disease and determine their impact on the patient's life in order that these can be treated and followed up by the most suitable professional. These recommendations could serve as a basis for redesigning IBD services or processes and as justification for the training of healthcare personnel.

Daily hassles score associates with the somatic and psychological health of patients with Crohn's disease

OBJECTIVE

To examine the associations of daily hassles with the somatic and psychological health of Crohn's disease (CD) patients.

METHOD

A cross-sectional study of 400 self-selected adult CD patients was performed with completion of demographic, medical, and psychosocial questionnaires: economic status; Patient Harvey-Bradshaw Index of disease activity; Daily Hassles Scale (DHS); Short Inflammatory Bowel Disease Questionnaire (SIBDQ) and Short-Form Health Survey (SF-36 Physical and Mental Health) quality of life measures; Brief Symptom Inventory of psychological stress with summary Global Severity Index (GSI); Family Assessment Device; and List of Threatening Life Experiences. Analyses included correlations, regressions, and Sobel test statistic.

RESULTS

The patients were aged 38.7 ± 14.1 years, 61% female and 67% working. The Patient Harvey-Bradshaw Index was 5.52 ± 4.87. The DHS was 88.0 ± 23.2, similar in men and women, higher in smokers, and increased with greater disease activity (p < .001). The most commonly reported hassles were time, social, and work. DHS had significant negative correlations with age, disease duration, and economic status and positive correlations with GSI, SF-36, and SIBDQ. An increased Daily Hassles score was associated with reduced SIBDQ (p < .001) and SF-36 Mental Health (p < .001) and increased GSI (p < .001) and Patient Harvey-Bradshaw Index (p < .001). This effect of DHS on Patient Harvey-Bradshaw Index was mediated by GSI (Sobel t = 6.09, p < 0.001).

CONCLUSION

Daily hassles in CD patients are shown for the first time to be associated with increased psychological stress and disease activity and reduced quality of life and lower economic status. This has psychotherapeutic implications.

Evaluating clinical, dietary, and psychological risk factors for relapse of ulcerative colitis in clinical, endoscopic, and histological remission

BACKGROUND AND AIM

The literature on possible factors that could trigger a relapse in patients with ulcerative colitis (UC) in clinical, endoscopic, and histological remission on long-term follow up is scarce. To determine the relapse rate in patients with UC in clinical, endoscopic, and histological remission and identify factors that may influence the risk of relapse.

METHODS

Patients with UC in clinical, endoscopic, and histological remission were enrolled between January and July 2010 and followed up for 1 year to determine the effect of clinical, dietary, and psychological factors on relapse. Information regarding factors that may affect relapse such as infection, antibiotic, or non-steroidal anti-inflammatory drugs (NSAIDs) use and any other factor that the patient felt important and compliance with medications was obtained.

RESULTS

Ninety-seven patients (59 males, mean age 39 ± 11.9 years) were followed up for a mean duration of 9 ± 2.3 months. Eighteen (18.6%) relapsed with the median time to relapse being 3.5 months. On univariate analysis, more relapsers had significantly higher NSAIDs use within 15 days of relapse, respiratory tract infection within 4 weeks, use of steroids more than once in past, higher consumption of calcium, riboflavin, and vitamin A, and lower consumption of sugars. On multivariate analysis, NSAIDs use (HR [95% CI]: 6.41 [1.88-21.9]) and intake of vitamin A (HR [95% CI]: 1.008 [1.000-1.016]) were statistically significant predictors of relapse.

CONCLUSION

With a relapse rate of 18.6% over a follow up of 9 months in patients with UC in clinical, endoscopic, and histological remission, independent predictors of relapse were history of NSAIDs use within 15 days of relapse and higher intake of vitamin A.

Prevalence and effectiveness of psychiatric treatments for patients with IBD: A systematic literature review

OBJECTIVES

Higher prevalence of psychiatric disorders, such as anxiety and depression, has been found in people with Crohn's disease and Ulcerative Colitis compared to the general population. Nowadays, international guidelines advocate psychotherapy and psycho-pharmacological treatments as playing an important role in IBD care. The main goal of this systematic literature review was summarize the evidence on the utilization and effectiveness of treatments for depression and anxiety in persons with IBD.

METHODS

A systematic literature review was conducted using three different electronic databases: MEDLINE, PsychINFO, and EMBASE to identify studies reporting the prevalence and efficacy of psycho-pharmacological and psychotherapeutic treatments for IBD. A quality appraisal was conducted using several scales as appropriate for each study design. A narrative synthesis was also performed.

RESULTS

Forty-three studies were included. Although a high rate of psychoactive drug use was found in people with IBD, a low proportion of IBD patients have access to psychiatric referral. 1/3 of the studies found that psychotherapy was effective for improving the quality of life, perception of stress, anxiety and depression as well as disease. Antidepressants proved effective in reducing disease activity, gastrointestinal symptoms, anxiety and depression.

CONCLUSION

Our results suggest that psychiatric treatment should be implemented in IBD care. However, further studies are needed to confirm the findings of our systematic review.

A qualitative study exploring the experience of people with IBD and elevated symptoms of anxiety and low mood and the type of psychological help they would like

BACKGROUND

People with inflammatory bowel disease (IBD) are at increased risk of developing anxiety and low mood. We sought to explore the experience of people with IBD and moderate-severe symptoms of anxiety/low mood to identify psychological processes which could be targeted in psychological interventions, as well as the kind of psychological support preferred.

METHODS

Twenty-five participants with IBD and moderate-severe symptoms of anxiety/low mood were recruited for interview. Template analysis was utilised to analyse interview data. We explored the situations, cognitions and behaviour linked to symptoms of anxiety and low mood by people with IBD, as well as the kind of psychological help preferred.

RESULTS

Two themes were identified within participants accounts of symptoms of anxiety; 'under performance' and 'preventing an accident'. Two further themes were identified for symptoms of low mood; 'lack of understanding' and 'stigma'. Expertise and understanding was the main theme identified for the type of psychological help desired.

CONCLUSION

The analysis highlights situations, cognitions and behaviour linked to anxiety and low mood by people with IBD and the type of psychological support desired. Our findings link to the knowledge and competencies set for psychological therapist working with long-term conditions.

Complementary and Integrative Gastroenterology

Complementary and integrative medicine is developing within gastroenterology, expanding options particularly for inflammatory bowel disease, irritable bowel syndrome, and reflux esophagitis. This article encompasses new developments in complementary integrative medicine with an emphasis on herbal therapies. Studies of potential therapies have been advancing with increasing sophistication. The best studied with the most promising results in ulcerative colitis is the use of curcumin both for the induction and maintenance of remission. Other polyphenols, such as resveratrol and epigallocatechin-3-gallate, also have supportive data for ulcerative colitis. Mind-body approaches have been applied in these diseases with positive data, particularly for irritable bowel syndrome.

Management of the Psychological Impact of Inflammatory Bowel Disease: Perspective of Doctors and Patients-The ENMENTE Project

BACKGROUND

To explore the perception of patients and gastroenterologists specialized in inflammatory bowel disease (IBD) on the impact of psychological factors on IBD course and its management.

METHODS

Online surveys were sent to patients with IBD recruited from a national patient association and IBD specialists recruited from a national scientific society. These surveys were based on the results of a focus group and discussion group that explored the psychological aspects of IBD. Descriptive statistical analyses were performed, and the physicians' responses regarding impact and management were compared with those of a random patient sample.

RESULTS

Responses were obtained from 170 physicians and 903 patients. Most patients emphasized the impact of psychological aspects, namely anxiety and depression, related to suffering from IBD, with 28% declaring that they perceived health professionals to not be interested in this area. A third of the physicians declared not feeling qualified to detect psychological problems. Although 50% of doctors stated that they regularly enquire about these aspects in their clinics, the patients perceived that this was done only 25% of the time. Both groups agreed on the need of a psychologist in IBD care teams.

CONCLUSIONS

A discrepancy exists between physician and patient perceptions of the impact of psychological aspects in IBD, with patients perceiving higher impact and more under treatment than physicians. Given the influence of these aspects on patient well-being, it seems advisable to enrich professionals' training, improve the clinical management of psychological aspects of IBD, and probably include psychologists in IBD care teams.

Traumatic stress-induced persistent changes in DNA methylation regulate neuropeptide Y expression in rat jejunum

BACKGROUND

Stress-induced chronic neuropsychiatric conditions such as anxiety are often co-morbid with gastrointestinal malfunctions. While we find enduring anxiety-like symptoms following minimal traumatic brain injury (MTBI) in rats, gastrointestinal consequences of MTBI remain elusive.

METHODS

In this study, we examined the effects of MTBI on a major gut peptide, neuropeptide Y (NPY) and gut motility. DNA methylation was studied as a possible epigenetic mechanism operative in the regulation of NPY expression in the gut.

KEY RESULTS

Minimal traumatic brain injury reduced the gut motility 48 hours and 30 days after trauma. The expression of DNA methyltransferase isoforms (DNMT1, DNMT3a, and DNMT3b) was altered in the jejunum 48 hours and 30 days after MTBI. However, the mRNA levels of growth arrest and DNA damage 45 (GADD45) isoforms, GADD45a, and GADD45b, which are believed to be involved in active DNA demethylation, initially decreased at 48 hours but subsequently increased after 30 days of trauma. Similarly, DNA hypomethylation at the NPY promoter region in the jejunum was correlated with the increase in NPY mRNA and protein levels 30 days post-trauma. On the other hand, DNA hypomethylation at 48 hours was associated with a decline in NPY expression. Treatment with 5-azacytidine (5-AzaC), a DNMT inhibitor, retarded DNA methylation and restored the NPY mRNA levels in the jejunum of MTBI-induced rats.

CONCLUSIONS & INFERENCES

These results suggest that DNA demethylation could be operative as an epigenetic mechanism in the long-term regulation of NPY gene expression to alter the gut motility during traumatic stress.

A comprehensive review and update on Crohn's disease

The term inflammatory bowel disease (IBD) refers principally to two major categories of chronic relapsing inflammatory intestinal disorders: Crohn's disease (CD) and ulcerative colitis (UC). In the United States, it is currently estimated that about 1.5 million people suffer from IBD, causing considerable suffering, mortality and economic loss every year. Yet the cause of IBD is unknown, and until we understand more, prevention or cure will not be possible. There is a lot of variation in the incidence and prevalence of CD based on geographic region, environment, immigrant population, and ethnic groups. The annual incidence of CD in North America is reported to be 3.1-20.2 per 100,000 with a prevalence of 201 per 100,000 population. Based on the epidemiological, genetic and immunological data, CD is considered to be a heterogeneous disorder with multifactorial etiology in which genetics and environment interact to manifest the disease. Several genes have been studied so for with respect to CD, but thus far the strong and replicated associations have been identified with NOD2, IL23R and ATG16L1 genes. The risk factors implicated with CD include smoking, low fiber- high carbohydrate diet, altered microbiome and medications such as non-steroidal anti-inflammatory drugs. CD is typically characterized by transmural inflammation of the intestine and could affect any part of the gastrointestinal tract from mouth to perianal area. In terms of distribution of the disease 25% of the patients have colitis only, 25% is ileitis only and 50% have ileocolitis. The Montreal classification is based on the age at diagnosis (<16, 17-40, > 40), disease location (Ileal, colonic, Ileocolonic) and the disease behavior (nonstricturing/nonpenetrating, stricturing, penetrating). The key features for diagnosing CD comprises a combination of radiographic, endoscopic and pathological findings demonstrating focal, asymmetric, transmural or granulomatous features. Abdominal Computed tomography (CT) enterography is the most preferred first-line radiologic study used in the assessment of small bowel CD. The diagnostic accuracy of magnetic resonance enterography/enteroclysis is similar to that of CT scans and also prevents exposure to ionizing radiation. Endoscopic scores are considered to be the gold standard tool to measure the activity of CD and they are used more commonly in the clinical trials to measure the efficacy of various drugs on inducing and maintaining mucosal healing. The most common scoring systems used to measure clinical disease activity include Crohn's Disease Activity Index (CDAI), HBI- Harvey-Bradshaw index (HBI), short inflammatory bowel disease questionnaire (SIBDQ) and Lehmann score. Management of Crohn's disease has been seen as an evolving challenge owing to its widely heterogeneous manifestations, overlapping characteristics with other inflammatory disorders, often elusive extraintestinal manifestations and uncertain etiology. Therapeutic interventions are tailored to address symptomatic response and subsequent tolerance of the intervention. Chronology of treatment should favor treatment dose acute disease or "induction therapy", followed by maintenance of adequate response or remission, i.e. "maintenance therapy". The medications which are highly effective in inducing remission include steroids and Tumor Necrosis Factor (TNF) inhibitors. Medications used to maintain remission include 5-aminosalicyclic acid products, immunomodulators (Azathioprine, 6-mercaptopurine, methotrexate) and TNF inhibitors (infliximab, adalimumab, certolizumab and golimumab). Surgical interventions like bowel resection, stricturoplasty or drainage of abscess is required in up to two thirds of CD patients during their lifetime. The most common indications for surgical resection are medically refractory disease, perforation, persisting or recurrent obstruction, abscess not amenable to percutaneous drainage, intractable hemorrhage, dysplasia or cancer. Endoscopic recurrence in postoperative CD patients, as defined by Rutgeers score i2-i4 occur in 30-90% of the patients at the neoterminal ileum within 12 months of surgery and almost universally by 5 years. Treating CD requires a comprehensive care team including the patient, primary care provider, and gastroenterologist. In summary CD is a chronic inflammatory condition with a remitting and relapsing course primarily affecting relatively younger population with significant socioeconomic effects.

Systematic review with meta-analysis: the impact of a depressive state on disease course in adult inflammatory bowel disease

BACKGROUND

Despite a higher prevalence of psychosocial morbidity in Inflammatory Bowel Disease (IBD), the association between depressive state and disease course in IBD is poorly understood.

AIM

To investigate the impact of depressive state on disease course in IBD.

METHODS

We conducted a systematic review in MEDLINE, EMBASE, the Cochrane Database of Systematic Reviews and PsychINFO for prospective studies evaluating the impact of baseline depressive state on subsequent disease course in adult IBD.

RESULTS

Eleven studies matched our entry criteria, representing 3194 patients with IBD. Three reported on patients with ulcerative colitis (UC), four included patients with Crohn's disease (CD) exclusively, and four studies included both UC and CD. Five studies reported an association between depressive state and disease course. None of the UC-specific studies found any association. In three of four CD-specific studies, a relationship between depressive state and worsening disease course was found. In four of five studies including patients in remission at baseline, no association between depressive state and disease course was found. Pooled analysis of IBD studies with patients in clinical remission at baseline identified no association between depressive state and disease course (HR 1.04, 95%CI: 0.97-1.12).

CONCLUSION

There is limited evidence to support an association between depressive state and subsequent deterioration in disease course in IBD, but what data that exist are more supportive of an association with CD than UC. Baseline disease activity may be an important factor in this relationship. Further studies are needed to understand the relationship between mental health and outcomes in IBD.

Impact of inflammatory bowel disease on daily life: an online survey by the Korean Association for the Study of Intestinal Diseases

BACKGROUND/AIMS

Inflammatory bowel disease (IBD) is a chronic disabling gastrointestinal disorder that diminishes the quality of life of the affected individuals. Limited data are available regarding the impact of IBD on the daily life of Koreans.

METHODS

Self-administered, computer-aided, internet-based questionnaires were distributed to members of a Korean patient organization for IBD from March to April 2013, by the Korean Association for the Study of Intestinal Diseases.

RESULTS

A total of 599 patients with IBD (387 with Crohn's disease [CD] and 212 with ulcerative colitis [UC]) were enrolled. The majority of patients (81%) expressed feelings of fatigue, weakness, and being worn out in their daily lives during times of flare; this percentage was reduced to 61% during remission. Respondents were absent from work or school for an average period of 18 days because of illness, within the first 6 months; the majority of respondents (64%) felt stressed about their absence. Forty-six percent of the respondents reported having received unfair comments at work, or having suffered discrimination. Forty-seven percent of the respondents felt that IBD had negatively affected their income and earnings. Compared with patients with UC, those with CD reported a more frequent negative impact of IBD on work, or more economic burden. More than half of the respondents (61%) reported that IBD had prevented them from making or keeping friends.

CONCLUSIONS

IBD significantly impacts daily life, including work, education, and social relationships. Treatment that addresses the full spectrum of life of a patient would be more effective.

Factors Associated with Anxiety and Depression in Korean Patients with Inactive Inflammatory Bowel Disease

BACKGROUND/AIMS

Psychological distress is highly prevalent in patients with inflammatory bowel disease (IBD). We evaluated the disease characteristics and socioeconomic factors associated with anxiety and depression in Korean patients with quiescent IBD.

METHODS

In total, 142 IBD patients (67 with Crohn's disease [CD] and 75 with ulcerative colitis [UC]) completed self-report questionnaires, including the Hospital Anxiety and Depression Score, the Modified Morisky Adherence Scale-8, the socioeconomic deprivation score, and the Crohn's and Colitis Knowledge Score questionnaires.

RESULTS

In the CD group, 30 patients (44%) were anxious, and 10 patients (15%) were depressed; in the UC group, 31 patients (41%) were anxious, and 18 patients (24%) were depressed. Using multivariate analysis, in the CD group, socioeconomic deprivation was associated with anxiety (p=0.03), whereas disease duration (p=0.04) and socioeconomic deprivation (p=0.013) were associated with depression. In the UC group, there was no significant independent predictor of anxiety and/or depression; however, low income tended to be associated with depression (p=0.096).

CONCLUSIONS

Despite clinical remission, a significant number of IBD patients present with anxiety and depression. IBD patients in remission, particularly those who are socioeconomically deprived, should be provided with appropriate psychological support.

Healthcare maintenance in elderly patients with inflammatory bowel disease

The increasing number of older patients (age ≥60 years) with inflammatory bowel disease (IBD) highlights the importance of healthcare maintenance in this vulnerable population. Older IBD patients are more susceptible and have higher rates of many disease- and treatment-related adverse effects. Compared to younger IBD patients, older patients are at increased risk for infection, malignancy, bone disease, eye disease, malnutrition and thrombotic complications. Preventive strategies in the elderly differ from those in younger adults and are imperative. Changes to the immune system with aging can decrease the efficacy of vaccinations. Cancer screening guidelines in older IBD patients have to account for unique considerations, such as life expectancy, functional performance status, multimorbidity, financial status, and patient desires. Additionally, providers need to be vigilant in screening for osteoporosis, ocular disease, depression, and adverse events arising from polypharmacy.

Patient-Reported Outcomes of Quality of Life, Functioning, and GI/Psychiatric Symptom Severity in Patients with Inflammatory Bowel Disease (IBD)

BACKGROUND

Patients with inflammatory bowel disease (IBD) are at risk for psychiatric disorders that impact symptom experience and health-related quality of life (HRQOL). Therefore, comprehensive biopsychosocial assessments should be considered in ambulatory care settings. Patient-Reported Outcomes Measurement Information System (PROMIS) measures created by the National Institutes of Health have shown construct validity in a large IBD internet-based cohort, but their validity in ambulatory settings has not been examined. We sought to validate PROMIS patient-reported measures of HRQOL, functioning, and psychiatric symptom severity at a tertiary IBD clinic.

METHODS

Adult patients (n = 110) completed the PROMIS Global Health scale, PROMIS-29, SF-12, and WHODAS 2.0. Pearson's correlation coefficients (r) determined the relationships between scores to validate the PROMIS Global Health Physical and Mental metrics, compared with the SF-12 and WHODAS 2.0. We compared these measures by disease subtype of Crohn's disease or ulcerative colitis.

RESULTS

PROMIS measures were highly correlated (r range = 0.64-0.82) with standard measures of HRQOL and functioning. On the PROMIS Global Health measures, 20.9% had impaired physical health, and 13.7% had impaired mental health. Impairments were reported in pain interference (20% of patients), anxiety (18.2%), satisfaction with social role (15.5%), physical functioning (10.9%), fatigue (10%), depression (7.3%), and sleep disturbance (5.5%). Patients with Crohn's disease had worse scores than those with ulcerative colitis on measures of the global physical health (P = 0.027), physical functioning (P = 0.047), and pain interference (P = 0.0009).

CONCLUSIONS

PROMIS instruments provide valid assessment of HRQOL and functioning in ambulatory adults with IBD. Of note, patients with Crohn's disease demonstrated significantly worse impairments than those with ulcerative colitis.

An 18-month study of the effects of IBD symptomatology and emotion regulation on depressed mood

PURPOSE

Depressive symptomatology in IBD patients is known to predict disease activity, which, in turn, can increase depressive symptoms in perpetuating a cycle between depression and IBD symptomatology. The mechanisms that contribute to the relationship between disease activity and depressive symptoms are not clearly investigated yet. Since emotion regulation has been considered particularly relevant to define the impact of adverse experiences on different outcomes, the current study aimed to examine the longitudinal influence of two maladaptive emotion regulation processes, cognitive fusion and brooding, on the association between disease activity and depressed mood.

METHODS

This study was conducted over an 18-month period, using a sample of 116 IBD patients that completed self-report validated measures in three different waves. Correlation analyses and cross-lagged panel models were performed.

RESULTS

The main result from this study discovered that the experience of IBD symptomatology at baseline, although positively linked to the manifestation of depressed mood 18 months later (r = 0.25; p < 0.01), does not directly predict depressive symptoms. This relationship is rather indirect, as it is explained by the engagement in cognitive fusion (p = 0.028) and brooding (p = 0.017). These maladaptive emotion regulation processes, that were revealed to be consistent over time, link IBD symptoms with subsequent depressed mood.

CONCLUSIONS

These findings indicate that clinicians should be aware of the emotion regulation processes patients tend to use to handle difficult experiences. The inclusion of psychological assessments and interventions in the healthcare of IBD patients should be seriously considered. Further implications are discussed.

Identification of Depressive Signs in Patients and Their Family Members During iPad-based Audiovisual Sessions

Home parenteral nutrition requires a daily life-sustaining intravenous infusion over 12 hours. The daily intravenous infusion home care procedures are stringent, time-consuming tasks for patients and family caregivers who often experience depression. The purposes of this study were (1) to assess home parenteral nutrition patients and caregivers for depression and (2) to assess whether depressive signs can be seen during audiovisual discussion sessions using an Apple iPad Mini. In a clinical trial (N = 126), a subsample of 21 participants (16.7%) had depressive symptoms. Of those with depression, 13 participants were home parenteral nutrition patients and eight were family caregivers; ages ranged from 20 to 79 years (with 48.9 [standard deviation, 17.37] years); 76.2% were female. Individual assessments by the mental health nurse found factors related to depressive symptoms across all 21 participants. A different nurse observed participants for signs of depression when viewing the videotapes of the discussion sessions on audiovisual technology. Conclusions are that depression questionnaires, individual assessment, and observation using audiovisual technology can identify depressive symptoms. Considering the growing provision of healthcare at a distance, via technology, recommendations are to observe and assess for known signs and symptoms of depression during all audiovisual interactions.

Mind-Body Interventions for Pediatric Inflammatory Bowel Disease

Pediatric inflammatory bowel disease is an autoimmune disease that causes chronic inflammation of the gastrointestinal mucosa. There is emerging evidence that the brain–gut connection affects inflammatory bowel disease (IBD) patients more than previously thought. This is evidenced by comorbid mood disorders, irritable bowel symptoms concurrent with quiescent IBD, and the potential of psychosocial stressors to trigger IBD flares. Mind–body interventions such as psychotherapy, relaxation, mindfulness, biofeedback, yoga, and clinical hypnosis offer an adjunct to standard medical treatment for IBD. We will review the current evidence base for these mind–body interventions in the treatment of pediatric IBD, illustrate a case study, and offer suggestions for future research for this promising field.

Beneficial Effects of Education on Emotional Distress, Self-Management, and Coping in Patients with Inflammatory Bowel Disease: A Prospective Randomized Controlled Study

BACKGROUND

Patients with inflammatory bowel disease (IBD) suffer from various physical as well as psychological impairments, and patient education may help improve their well-being. Therefore, we developed a manualized education program for IBD patients addressing medical and psychological issues. This study aimed to evaluate it in a large controlled trial.

METHODS

A total of 181 IBD outpatients participated in a prospective, randomized, waitlist-controlled trial; assessments were made before as well as 2 weeks and 3 months after intervention. Analysis of covariance was used to assess intervention effects on disease-related worries and concerns (primary outcome), fear of progression, coping with anxiety, health competencies, health-related quality of life (HRQoL), perceived disease activity, symptoms of depression and anxiety, disease-related knowledge, and coping strategies. Participants' satisfaction with the program was also evaluated.

RESULTS

At 2 weeks and 3 months after intervention, we found significant large effects of our education program on skill and technique acquisition, knowledge, and coping with IBD. Moreover, we found significant medium effects on disease-related worries and concerns, fear of progression, coping with anxiety, constructive attitudes and approaches, as well as coping with disease-related negative emotions. The number of coping strategies used was significantly higher at 3 months. We did not find any effects on perceived disease activity, HRQoL, positive and active engagement in life, or symptoms of anxiety and depression. The program was rated very favorably by the attendees.

CONCLUSION

Our education program contributed to improvements in psychological distress, self-management skills, and coping and was appreciated by its attendees.
