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

The Burden of Work Productivity and Activity Impairment in Patients with Psoriasis, Psoriatic Arthritis, Ulcerative Colitis, and Crohn's Disease

BACKGROUND

Comparisons among autoimmune diseases enable understanding of the burden and factors associated with work productivity loss and impairment.

AIMS

The objective was to compare work productivity and activity and associated factors among patients with inflammatory bowel diseases and other autoimmune conditions.

METHODS

This cross-sectional study included employed, adult patients (age 20-64 years) in the CorEvitas Inflammatory Bowel Disease, Psoriasis, and Psoriatic Arthritis/Spondyloarthritis Registries between 5/2017 and 6/2020. Any patient-reported impairment on four domains of the Work Productivity and Activity Index (WPAI) was collected across registries. Prevalence for each autoimmune disease was reported and stratified by disease activity using direct age-sex-standardization. Factors associated with the presence of any WPAI were identified in logistic regression models.

RESULTS

A total of 7,169 patients with psoriasis (n = 4,768, 67%), psoriatic arthritis (n = 1,208, 17%), Crohn's disease (CD, n = 621, 9%), and ulcerative colitis (UC, n = 572, 8%) met inclusion criteria. Among patients not in remission across all disease cohorts, the age-sex-standardized prevalence of any presenteeism, work productivity loss, and activity impairment ranged from 54 to 97%. Patients with CD in remission had higher standardized prevalence of presenteeism (53% [48-57%]) and work productivity loss (54% [49-59%]), compared to those from other cohorts (presenteeism [range: 33-39%] and work productivity loss [range: 37-41%]). For all WPAI domains, the strongest adjusted associations were for moderate to severe disease activity and psychosocial symptoms.

CONCLUSIONS

Patients with moderate to severe disease activity reported the highest WPAI burden. However, patients in remission or mild disease activity also report some WPAI burden, emphasizing a multidisciplinary treatment approach to improve work productivity loss and impairment.

Disease-specific alterations in central fear network engagement during acquisition and extinction of conditioned interoceptive fear in inflammatory bowel disease

Interoceptive fear, which is shaped by associative threat learning and memory processes, plays a central role in abnormal interoception and psychiatric comorbidity in conditions of the gut-brain axis. Although animal and human studies support that acute inflammation induces brain alterations in the central fear network, mechanistic knowledge in patients with chronic inflammatory conditions remains sparse. We implemented a translational fear conditioning paradigm to elucidate central fear network reactivity in patients with quiescent inflammatory bowel disease (IBD), compared to patients with irritable bowel syndrome (IBS) and healthy controls (HC). Using functional magnetic resonance imaging, conditioned differential neural responses within regions of the fear network were analyzed during acquisition and extinction learning. In contrast to HC and IBS, IBD patients demonstrated distinctly altered engagement of key regions of the central fear network, including amygdala and hippocampus, during differential interoceptive fear learning, with more pronounced responses to conditioned safety relative to pain-predictive cues. Aberrant hippocampal responses correlated with chronic stress exclusively in IBD. During extinction, differential engagement was observed in IBD compared to IBS patients within amygdala, ventral anterior insula, and thalamus. No group differences were found in changes of cue valence as a behavioral measure of fear acquisition and extinction. Together, the disease-specific alterations in neural responses during interoceptive fear conditioning in quiescent IBD suggest persisting effects of recurring intestinal inflammation on central fear network reactivity. Given the crucial role of interoceptive fear in abnormal interoception, these findings point towards inflammation-related brain alterations as one trajectory to bodily symptom chronicity and psychiatric comorbidity. Patients with inflammatory conditions of the gut-brain axis may benefit from tailored treatment approaches targeting maladaptive interoceptive fear.

Post-traumatic stress disorder symptoms are frequent among inflammatory bowel disease patients of South Asian descent-A case-control study

BACKGROUND

Post-traumatic stress (PTS) is the psycho-physiological response to a traumatic or life-threatening event and is implicated in inflammatory bowel disease (IBD). IBD-PTS is present in up to 30% of white, non-Hispanic patients. The rates of IBD in Asian populations are expanding, making the exploration of IBD-PTS in this population imperative.

METHODS

Adult patients of South/Southeast (S/SE) Asian decent with IBD for more than 6 months were recruited online via social media and patient-support groups. Participants completed the post-traumatic stress disorder (PTSD) Checklist-5 (PCL-5), the United States National Institutes of Health's Patient-Reported Outcomes Measurement Information System (NIH-PROMIS) -43 profile and demographics. S/SE Asian participants were age and sex matched (1:2) with randomly selected white, non-Hispanic controls. Statistical analyses evaluated differences in IBD-PTS symptoms between groups, the relationship between disease severity and health-related quality of life (HRQoL) and predictors of IBD-PTS severity.

RESULTS

Forty-seven per cent of the 51 S/SE Asian participants met the diagnostic cut-off for PTSD on the PCL-5 compared to 13.6% of 110 IBD controls. The mean global score on the PCL-5 was three times higher in S/SE Asians. Patients of S/SE Asian decent were over five times more likely to have PTSD due to their IBD experiences than controls, nearly doubling when controlling for disease activity. More severe IBD-PTS was present in S/SE Asian patients with active disease and those with extraintestinal manifestations. Higher global levels of IBD-PTS were associated with poorer HRQoL in S/SE Asians where increased hyperarousal from IBD-PTS predicted more sleep disturbance.

CONCLUSIONS

S/SE Asian patients are five times more likely to experience IBD-PTS than their white, non-Hispanic counterparts. Several cultural factors lead to IBD-PTS in S/SE Asian patients that must be considered by IBD providers. Preventing, screening for and treating IBD-PTS in this population appears warranted.

Pre-treatment expectations and their influence on subjective symptom change in Crohn's disease

BACKGROUND

Treatment expectations reportedly shape treatment outcomes, but have not been studied in the context of multimodal therapy in Crohn's disease (CD). Therefore, the current study investigated the role of treatment expectations for subjective symptom changes in CD patients who have undergone an integrative multimodal therapy program.

METHODS

Validated questionnaires were completed at the start of the treatment program and post intervention. Pre-treatment expectations and experienced symptom change were assessed with the Generic Rating Scale for Previous Treatment Experiences, Treatment Expectations, and Treatment Effects (GEEE); stress levels were quantified with the Perceived Stress Scale (PSS-10) and disease specific quality of life was quantified with the disease-specific Inflammatory Bowel Disease Questionnaire (IBDQ). We performed multiple linear and Bayesian regression to determine how expectations related to symptom change.

RESULTS

N = 71 CD patients (66.2% female) were included. Stronger expectations regarding symptom improvement (b = 0.422, t = 3.70, p < .001) were associated with higher experienced symptom improvement. Additionally, Bayesian analysis provided strong evidence for including improvement expectations as a predictor of improvement experience (BFinclusion = 13.78).

CONCLUSIONS

In line with research in other disorders, we found that positive treatment expectations were associated with experienced symptom improvement. In contrast, we found no indication that an experience of symptom worsening was associated with positive or negative baseline treatment expectations. Induction of positive expectations might be a potential avenue for improving treatment outcomes in CD therapy.

Psychological impairment in inflammatory bowel diseases: the key role of coping and defense mechanisms

A comprehensive investigation of psychological features in chronic patients is very important for tailoring effective treatments. In this study we tested anxiety, depression, health related quality of life (HR-QoL), alexithymia, coping styles, and defense mechanisms, in eighty-four patients with Crohn disease (CD) and ulcerative colitis (UC). Participants reported low to moderate HRQoL and anxiety, apart from alexithymia. Women experienced lower QoL and higher levels of anxiety and depressive symptoms. Coping and defense strategies were related to distress symptoms and QoL. Positive attitude and principalization, showed negative associations with depression, anxiety and alexithymia and were also found to be associated with mental health. CD patients used significantly more turning against objects (p=0.02) and projections (p=0.01) and UC patients used more reversal (p=0.04). Elderly women showed higher anxiety symptoms and lower perceived QoL. Multiple regression analysis revealed anxiety and depression were independently associated with QoL. Significant differences emerged in defense styles among CD and UC. CD participants used more maladaptive coping and defense styles which were related to mental distress, depression and anxiety, together with higher level of alexithymia. Findings suggest that psychological aspects play a key role in mental health in patients suffering from inflammatory bowel diseases. A multi-integrated clinical strategy including psychotherapeutic interventions should be considered in treating CD and UC.

A randomized controlled trial of a proactive analgesic protocol demonstrates reduced opioid use among hospitalized adults with inflammatory bowel disease

Most hospitalized patients with inflammatory bowel disease (IBD) experience pain. Despite the known risks associated with opioids in IBD including risk for misuse, overdose, infection, readmission, and even death, opioid use is more prevalent in IBD than any other chronic gastrointestinal condition. Most hospitalized IBD patients receive opioids; however, opioids have not been shown to improve pain during hospitalization. We conducted a randomized controlled trial in hospitalized patients with IBD to evaluate the impact of a proactive opioid-sparing analgesic protocol. Wearable devices measured activity and sleep throughout their hospitalization. Chronic opioid users, post-operative, and pregnant patients were excluded. The primary endpoint was a change in pain scores from admission to discharge. Secondary endpoints included opioid use, functional activity, sleep duration and quality, and length of stay. Of 329 adults with IBD evaluated for eligibility, 33 were enrolled and randomized to the intervention or usual care. Both the intervention and control group demonstrated significant decreases in pain scores from admission to discharge (- 2.6 ± 2.6 vs. - 3.0 ± 3.2). Those randomized to the intervention tended to have lower pain scores than the control group regardless of hospital day (3.02 ± 0.90 vs. 4.29 ± 0.81, p = 0.059), used significantly fewer opioids (daily MME 11.8 ± 15.3 vs. 30.9 ± 42.2, p = 0.027), and had a significantly higher step count by Day 4 (2330 ± 1709 vs. 1050 ± 1214; p = 0.014). There were no differences in sleep duration, sleep quality, readmission, or length-of-stay between the two groups. A proactive analgesic protocol does not result in worsening pain but does significantly reduce opioid-use in hospitalized IBD patients.Clinical trial registration number: NCT03798405 (Registered 10/01/2019).

Psychosocial factors associated with j-pouch surgery for patients with IBD: a scoping review

BACKGROUND

Ulcerative colitis and Crohn's disease are subtypes of inflammatory bowel disease: a chronic condition of unclear etiology characterized by inflammation of the small and large intestine. Inflammatory bowel disease is managed with diet, medications, and surgeries, with the most common surgery, recommended to ulcerative colitis patients being j-pouch surgery.

PURPOSE

To assess the current literature concerning psychosocial factors associated with j-pouch surgery for patients with inflammatory bowel disease.

METHODS

A systematic scoping review of the empirical and grey literature was conducted for original research on j-pouch surgery and psychosocial variables. Eight databases were searched: Medline, PsychInfo, CINAHL, EBM Reviews, ProQuest Dissertations and Theses Global, ResearchGate, Prospero, and PrePubMed.

RESULTS

Thirty-nine articles were identified. Many studies (n = 18) adopted a case-series design, and none examined psychosocial interventions. The most popular psychosocial variables assessed were quality of life (n = 34) and those associated with sexual health and functioning (n = 9).

CONCLUSIONS

Despite being an established surgical procedure, little research has examined the psychosocial implications of j-pouch surgery. As such, clinicians lack a robust understanding of how this procedure affects patients' psychiatric and social status and adaptive abilities. There is a need for high-quality research utilizing validated measures and rigorous design methodologies with control populations.

Abdominal pain in patients with inflammatory bowel disease in remission: A prospective study on contributing factors

BACKGROUND

Abdominal pain is highly prevalent in patients with inflammatory bowel disease (IBD) in remission, but the aetiology is incompletely understood.

AIM

To investigate the association of clinical, lifestyle and psychosocial factors with abdominal pain in patients with IBD in remission.

METHODS

We performed a prospective multicentre study enrolling consecutive patients with IBD. Data were collected between 1 January 2020 and 1 July 2021, using myIBDcoach, an established remote monitoring platform for IBD. Chronic abdominal pain in IBD in remission (IBDremissionPain+) was defined as abdominal pain score ≥3 (0-10 NRS) on ≥1/3 of all assessments, combined with faecal calprotectin <150 μg/g in 90 days around periodic assessments. Disease activity, lifestyle and psychosocial factors were assessed every 1-3 months during 18 months. Using linear mixed models, the association of these factors with abdominal pain over time was analysed.

RESULTS

We included 559 patients, of whom 429 (76.7%) remained in biochemical remission. Of these, 198 (46.2%) fulfilled the criteria for chronic abdominal pain. IBDremissionPain+ patients were characterised by female sex, younger age, higher BMI, and shorter disease duration. They reported more often or higher levels of stress, fatigue, depressive and anxiety symptoms, and life events (all p < 0.001). In the multivariable analysis, sex, disease entity, fatigue, depressive symptoms and life events were associated with abdominal pain over time (all p < 0.05).

CONCLUSION

In this cohort of patients with IBD in remission, abdominal pain was common and associated with psychosocial factors. A more holistic treatment approach for patients with IBD suffering from abdominal pain may improve quality of care and subjective wellbeing.

Impact of Opioid Use on the Natural History of Inflammatory Bowel Disease: Prospective Longitudinal Follow-up Study

BACKGROUND

Opioid use is increasingly prevalent amongst patients with inflammatory bowel disease (IBD), but whether opioids have deleterious effects, or their use is merely linked with more severe disease, is unclear. We conducted a longitudinal follow-up study examining this issue.

METHODS

Data on demographics, gastrointestinal and psychological symptoms, quality of life, and opioid use were recorded at baseline. Data on healthcare use and adverse disease outcomes were obtained from a review of electronic medical records at 12 months. Characteristics at baseline of those using opioids and those who were not were compared, in addition to occurrence of flare, prescription of glucocorticosteroids, treatment escalation, hospitalization, or intestinal resection during the 12 months of follow-up.

RESULTS

Of 1029 eligible participants, 116 (11.3%) were taking opioids at baseline. Medium (odds ratio [OR], 4.67; 95% confidence interval [CI], 1.61-13.6) or high (OR, 8.03; 95% CI, 2.21-29.2) levels of somatoform symptom-reporting and use of antidepressants (OR, 2.54; 95% CI, 1.34-4.84) or glucocorticosteroids (OR, 6.63; 95% CI, 2.26-19.5; P < .01 for all analyses) were independently associated with opioid use. Following multivariate analysis, opioid users were significantly more likely to undergo intestinal resection (hazard ratio,  7.09; 95% CI, 1.63 to 30.9; P = .009), particularly when codeine or dihydrocodeine were excluded (hazard ratio, 42.9; 95% CI, 3.36 to 548; P = .004).

CONCLUSIONS

Opioid use in IBD is associated with psychological comorbidity and increased risk of intestinal resection, particularly in stronger formulations. Future studies should stratify the risk of individual opioids, so that robust prescribing algorithms can be developed and assess whether addressing psychological factors in routine IBD care could be an effective opioid avoidance strategy.

Chronic abdominal pain in inflammatory bowel disease: a practical guide

Pain is common in inflammatory bowel disease (IBD), yet many patients feel their pain is not addressed by healthcare professionals. Listening to a patient's concerns about pain, assessing symptoms and acknowledging the impact these have on daily life remain crucial steps in addressing pain in IBD. While acute pain may be effectively controlled by pain medication, chronic pain is more complex and often pharmacological therapies, particularly opioids, are ineffective. Low-dose tricyclic antidepressants and psychological approaches, including cognitive-behavioural therapy, have shown some promise in offering effective pain management while lifestyle changes such as a trial of low-fermentable oligosaccharides, disaccharides, monosaccharides and polyols diet in those with overlapping irritable bowel syndrome may also reduce pain. Patients benefit from a long-term, trusting relationship with their healthcare professional to allow a holistic approach combining pharmacological, psychological, lifestyle and dietary approaches to chronic pain. We present a practical review to facilitate management of chronic abdominal pain in IBD.

Abdominal Pain in Inflammatory Bowel Disease: An Evidence-Based, Multidisciplinary Review

Abdominal pain is one of the most common and impactful symptoms associated with inflammatory bowel disease (IBD), including both Crohn's disease and ulcerative colitis. A great deal of research has been undertaken over the past several years to improve our understanding and to optimize management of this issue. Unfortunately, there is still significant confusion about the underlying pathophysiology of abdominal pain in these conditions and the evidence underlying treatment options in this context. There is also a relative paucity of comprehensive reviews on this topic, including those that simultaneously evaluate pharmacological and nonpharmacological therapeutic options. In this review, our multidisciplinary team examines evidence for various currently available medical, surgical, and other analgesic options to manage abdominal pain in IBD.

The Occurrence of Gluten-Related Antibodies, Sensitization to Selected Food Allergens, and Antibodies against Intrinsic Factor in Adult Patients with Diarrhea-Predominant Irritable Bowel Syndrome

Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder. Due to the possible overlap of IBS clinical symptoms with gluten-related diseases, food allergies, and autoimmune gastritis (AIG), the aim of this study was to present the frequency of anti-tissue transglutaminase 2 (TTG2) autoantibodies, anti-deamidated gluten peptide (DGP) antibodies, specific immunoglobulin E antibodies (sIgE) to selected food allergens, and anti-intrinsic factor (IF) autoantibodies in adult patients with diarrhea-predominant IBS (IBS-D). The study involved 244 patients (170 women) aged 18-75 years. The antibodies were measured with the use of multiparametric immunoassays. Elevated antibody concentrations, irrespective of the class of tested antibody, occurred in 44 patients (17.6%), including 11 patients (4.5%) with positive DGP antibodies, four patients (1.6%) with TTG2 autoantibodies, six patients (2.5%) with IF autoantibodies, and 31 patients (12.7%) with sIgE to food allergens. Sensitization to gluten, proteins from cow's milk, and bovine serum albumin was found in 2.1%, 5.3%, and 9.0% of patients, respectively. Our study showed a high percentage of positive results for the tested antibodies in the IBD-D patients, which indicates the need to perform serological tests for CD, food allergies, and AIG in this group of patients.

Randomised clinical trial: Psychological intervention improves work productivity and daily activity by reducing abdominal pain and fatigue in Crohn's disease

BACKGROUND

Chronic abdominal pain and fatigue are characteristics of Crohn's disease (CD) and contribute to functional impairments.

AIMS

To examine whether CD-tailored cognitive-behavioural and mindfulness intervention (COBMINDEX) is effective in reducing abdominal pain and fatigue in patients with CD and whether changes in abdominal pain and fatigue mediate any beneficial effects of COBMINDEX on impairments in work productivity and daily activities.

METHODS

This is a secondary analysis of a parallel-group multicentre randomised controlled trial. Patients with mild-to-moderate CD (n = 142) were randomised into either intervention group receiving COBMINDEX, or control group receiving treatment-as-usual for 3 months followed by COBMINDEX. Complete data were collected from 120 patients (34.0 ± 10.7 years, 62.5% female, intervention = 60, control = 60). Analysis of covariance assessed group differences in 3-month follow-up scores, controlling for baseline scores. Multiple parallel mediation analysis assessed the proposed mechanisms for the entire sample.

RESULTS

The intervention group demonstrated significantly lower levels of abdominal pain (F = 17.46, p < 0.001, η² _p  = 0.13), fatigue (F = 7.26, p = 0.008, η² _p  = 0.06) and impairments at work (F = 4.82, p = 0.032, η² _p  = 0.07) and daily activities (F = 6.26, p = 0.014, η² _p  = 0.05), compared with treatment-as-usual. Moreover, changes in abdominal pain and fatigue significantly mediated the beneficial effects of COBMINDEX on patients' work productivity (b = -9.90, SE = 2.86, 95% CI: -16.11 to -4.94) and daily activities (b = -9.65, SE = 1.91, 95% CI: -13.77 to 6.35), independent of changes in disease activity.

CONCLUSIONS

COBMINDEX is effective at reducing abdominal pain and fatigue in patients with CD, which in turn leads to improvement in functioning. Clinicians should incorporate screening for severe abdominal pain and fatigue and consider offering cognitive-behavioural and mindfulness training.

A psychometric evaluation of the Italian short version of the Fear of Pain Questionnaire-III: Psychometric properties, measurement invariance across gender, convergent, and discriminant validity

Introduction

The Fear of Pain Questionnaire-III (FPQ-III) is a self-assessment instrument developed specifically to measure fear based on various pain stimuli converging on three factors: severe pain, medical pain, and minor pain. It actually remains the most studied and internationally used tool even in its short versions. The aim of this work was to propose a new validation study oriented to confirm the good psychometric properties of a short model of the FPQ-III for the Italian context.

Methods

A large sample of participants was recruited (n  = 1,064) and Exploratory Factor Analysis (EFA) as well as Confirmatory Factor Analysis (CFA) were performed. Measurement invariance of the FPQ-III across gender was also evaluated. In order to examine convergent validity, a further convenient sample (n  = 292) was used and variables related to the individual's pain experience, locus of control and coping orientations were assessed. A final discriminant assessment using experimental manipulation through fear eliciting videos was performed.

Results

The three factors structure of the 13-item version of the questionnaire was confirmed (χ² = 148.092, CFI = 0.971, TLI = 0.962, RMSEA = 0.046, RMSEA 90% CI = 0.037-0.056) as well as the measurement invariance across gender. Item internal reliability was satisfactory. The results provided evidence of the good predictive validity of the FPQ-III and the discriminant assessment demonstrated that the instrument is suitable in detecting changes in fear of pain induced by specific situational conditions.

Discussion

The scale in this short version is suitable for quickly and efficiently gathering information about the perceived intensity of such anticipatory fears that might affect even the healthy person dysfunctionally.

A Phenomenological Investigation of Trauma in 18 Adults Living With Inflammatory Bowel Disease

While trauma is recognized as being common in Inflammatory Bowel Disease (IBD) cohorts, limited research has explored how trauma impacts the lived experience of IBD. The aim of this study was to develop an understanding of how trauma impacts the experience of living with IBD and its subsequent management. An interpretative phenomenological analysis with thematic analysis was conducted. Eighteen adults with IBD participated in this qualitative research study. Key themes identified included: (1) Trauma was associated with the journey of IBD; (2) the impact of IBD and trauma, and (3) coping strategies. Pre-existing non-IBD trauma was prevalent, with several participants reporting links between traumatic events and their IBD diagnosis. Experiences of IBD trauma were described by participants across all stages of their illness journey. The study can assist healthcare professionals to better understand the experience of living with IBD and trauma and the factors that can contribute to traumatic responses.

The Interplay of Biopsychosocial Factors and Quality of Life in Inflammatory Bowel Diseases: A Network Analysis

GOAL

The aim of this study was to investigate the network of biopsychosocial factors and quality of life (QoL) in persons with inflammatory bowel diseases (IBDs) and explore the influence of psychological factors on the course of the disease.

BACKGROUND

QoL of persons with IBD depends on disease activity but also on numerous interacting psychosocial factors. The influence of psychosocial factors on the disease course in controversially discussed.

MATERIALS AND METHODS

In 2 independent IBD samples (sample 1: n=209, anonymous internet survey; sample 2: n=84, outpatients with active disease), we measured QoL, anxiety, depression, illness identity, self-esteem, loneliness, childhood trauma, and visceral sensitivity with questionnaires. In addition, fatigue, hemoglobin levels, and response to therapy were assessed in sample 2. We estimated multiple regularized partial correlation networks and conducted accuracy and stability tests of the networks.

RESULTS

In both samples, QoL had the strongest relationships with visceral sensitivity and the illness identity engulfment. Depression was the most central factor in the networks. Baseline depression scores, visceral sensitivity, and engulfment were associated with response to therapy in sample 2.

CONCLUSIONS

This first network study to assess the interplay between biopsychosocial factors and QoL in IBD reveals a comparable network structure in 2 samples. Results partly replicate findings from previous studies with regard to the importance of depression and yield information on the central role of the newly introduced concepts of illness identity and visceral sensitivity. Preliminary findings point to an influence of these parameters on the disease course, which indicates their role as a possible target in individualized therapy.

A network pharmacology approach to predict potential targets and mechanisms of "Ramulus Cinnamomi (cassiae) - Paeonia lactiflora" herb pair in the treatment of chronic pain with comorbid anxiety and depression

BACKGROUND

Traditional Chinese medicine (TCM) prescriptions have multiple bioactive properties. "Gui Zhi-Shao Yao" herb pair is widely used to treat chronic pain (CP), as well as anxiety and depression. However, its related targets and underlying mechanisms have not been deciphered.

METHODS

In this study, the network pharmacology method was used to explore the bioactive components and targets of "Gui Zhi-Shao Yao" herb pair and further elucidate its potential biological mechanisms of action in the treatment of CP with comorbid anxiety disorder (AD) and mental depression (MD).

RESULTS

Following a series of analyses, we identified 15 active compounds, hitting 130 potential targets. After the intersections the targets of this herb pair and CP, AD and MD - sorted by the value of degree - nine targets were identified as the vital ones: Akt1, IL6, TNF, PTGS2, JUN, CASP3, MAPK8, PPARγ and NOS3. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis results demonstrated 11 pathways, such as AGE-RAGE signalling pathway, IL-17 signalling pathway, TNF signalling pathway, which primarily participate in the pathological processes.

CONCLUSIONS

This study preliminarily predicted and verified the pharmacological and molecular mechanisms of "Gui Zhi-Shao Yao" herb pair for treating CP with comorbid AD and MD from a holistic perspective. In vivo and in vitro experiments will be required to further investigate the mechanisms.KEY MESSAGEA network pharmacology approach was applied to identify key targets and molecular mechanisms.Nine targets were regarded as the vital targets for chronic pain with comorbid anxiety and depression.Predicted 11 pathways were the potential therapy targets and pharmacological mechanism of "Gui Zhi-Shao Yao" herb pair.

A Missing Piece of the Puzzle: Patient and Provider Perspectives on Pain Management Needs and Opioid Prescribing in Inflammatory Bowel Disease Care

Background

Recent data have shown high rates of opioid misuse among inflammatory bowel disease (IBD) patients. We conducted a qualitative study to explore IBD patient and provider perceptions and experiences with pain management and opioid prescribing.

Methods

We conducted a focus group with IBD patients and semistructured interviews with IBD-focused physicians and nurses. We used an inductive approach for analysis and the constant comparison method to develop and refine codes and identify prominent themes. We analyzed interview and focus group data concurrently to triangulate themes.

Results

Nine patients and 10 providers participated. We grouped themes into 3 categories: (1) current practices to manage pain; (2) perceived pain management challenges; and (3) suggestions to optimize pain management. In the first category (current practices), both patients and providers reported building long-term patient-provider relationships and the importance of exploring nonpharmacologic pain management strategies. Patients reported proactively trying remedies infrequently recommended by IBD providers. In the second category (pain management challenges), patients and providers reported concerns about opioid use and having limited options to treat pain safely. Patients discussed chronic pain and having few solutions to manage it. In the third category, providers shared suggestions for improvement such as increasing use of nonpharmacologic pain management strategies and enhancing care coordination.

Conclusions

Despite some common themes between the 2 groups, we identified some pain management needs (eg, addressing chronic pain) that matter to patients but were seldom discussed by IBD providers. Addressing these areas of potential disconnect is essential to optimize pain management safety in IBD care.

De Novo Ostomy Placement Is Associated with Increased Outpatient Opioid Use In Patients with Inflammatory Bowel Disease

BACKGROUND/AIMS

Opioid use is associated with poor outcomes in patients with inflammatory bowel disease (IBD). We aimed to identify novel factors associated with increased outpatient opioid (OPRx) use following IBD-related hospitalization.

METHODS

This was a retrospective cohort study of IBD patients ≥ 18 years old, hospitalized during 2018. The primary outcome was receiving ≥ 1(OPRx) in the year following index hospitalization (IH), excluding prescriptions written within 2 weeks of discharge. Secondary outcomes included having 1-2 vs ≥ 3 OPRx and rates of healthcare utilization. Univariate and multivariate analyses tested associations with OPRx.

RESULTS

Of 526 patients analyzed, 209 (40%) received at least 1 OPRx; with a median of 2 [1-3] OPRx. Presence or placement of ostomy at IH, exposure to opioids during IH, ulcerative colitis (UC), mental health comorbidities, admission for surgery and managed on the surgical service, and IBD surgery within 1 year prior to IH were associated with ≥ 1 OPRx on univariate analysis. On multivariable analysis, UC, ostomy placement during IH, anxiety, and inpatient opioid exposure were independently associated with ≥ 1 OPRx. A majority (> 70%) of both inpatient and outpatient opioid prescriptions were written by surgeons. Patients requiring ≥ 3 OPRx had the highest rates of unplanned IBD surgery (56% p = 0.04), all-cause repeat hospitalization (81%, p = 0.003), and IBD-related repeat hospitalization (77%, p = 0.007) in the year following IH.

CONCLUSIONS

A multimodal approach to pain management for IBD patients, as well as increased recognition that any patient with a de novo ostomy is at particular risk of opioid use, is needed.

Abdominal Pain in Inflammatory Bowel Diseases: A Clinical Challenge

Up to 60% of inflammatory bowel disease (IBD) patients experience abdominal pain in their lifetime regardless of disease activity. Pain negatively affects different areas of daily life and particularly impacts the quality of life of IBD patients. This review provides a comprehensive overview of the multifactorial etiology implicated in the chronic abdominal pain of IBD patients including peripheral sensitization by inflammation, coexistent irritable bowel syndrome, visceral hypersensitivity, alteration of the brain–gut axis, and the multiple factors contributing to pain persistence. Despite the optimal management of intestinal inflammation, chronic abdominal pain can persist, and pharmacological and non-pharmacological approaches are necessary. Integrating psychological support in care models in IBD could decrease disease burden and health care costs. Consequently, a multidisciplinary approach similar to that used for other chronic pain conditions should be recommended.

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

Background

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

Objective

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

Methods

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

Results

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

Conclusions

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

Somatosensory assessments in patients with inflammatory bowel disease: a cross-sectional study examining pain processing pathways and the role of multiple patient factors

BACKGROUND

Pain affects the majority of patients with inflammatory bowel disease (IBD), where pain experiences may be influenced by multiple patient factors and changes within central pain processing pathways, termed central sensitization. The current study aimed to investigate pain processing pathways in patients with IBD through somatosensory testing and associations with multiple patient factors.

METHODS

A cross-sectional study of adults with IBD. Assessments included: somatosensory tests [i.e. pressure pain thresholds (PPT), temporal summation (TS), conditioned pain modulation (CPM)], and patient factors (i.e. demographics, comorbidity, sleep quality, psychological, pain severity and interference, and IBD features). Multiple regression analyses explored associations between somatosensory tests and multiple patient factors.

RESULTS

Decreased CPM in participants (N = 51) was associated with worse abdominal pain severity and use of biologic therapies (R2 = 0.30, F(5,44) = 5.18, P = 0.001). Increased TS was associated with biologic use (R2 = 0.11, F(1,49) = 6.13, P = 0.017). Decreased PPT at the low back (R2 = 0.29, F(2,48) = 11.21, P < 0.001) and Tibialis anterior (R2 = 0.41, F(2,48) = 18.26, P < 0.001) were associated with female sex and the absence of a stoma.

CONCLUSION

Study results demonstrated associations between multiple patient factors and somatosensory tests in patients with IBD. The absence of a stoma and female sex was associated with greater sensitivity to pressure in two remote body regions, suggestive of widespread hyperalgesia. Worse abdominal pain severity and biologic use were associated with decreased pain inhibition, and biologic use was also associated with increased pain facilitation. These findings suggest the presence of altered pain processing and mechanisms of central sensitization in patients with IBD.

Improvement in constipation and diarrhea is associated with improved abdominal pain in patients with functional bowel disorders

BACKGROUND

Abdominal pain is a bothersome and lifestyle limiting symptom in patients with functional bowel disorders. It is associated with decreased quality of life in affected individuals, as well as significant annual healthcare expenditure. Knowledge of specific factors that predict improvement in abdominal pain in those with functional bowel disorders is thus far limited.

METHODS

Consecutive patients presenting for outpatient care at a major academic medical center between October 2017 and March 2020 completed an electronic symptom survey prior to initial clinic visit, and again after 3 months. The Rome IV questionnaires for functional dyspepsia, irritable bowel syndrome, functional constipation, and functional diarrhea were all included. Additionally, all subjects completed the Patient Reported Outcomes Measurement Information System Anxiety, Depression, and sleep disturbance questionnaires. Patients with a diagnosis of a Rome IV functional gastrointestinal disorder without any organic cause for symptoms were identified based on both chart review as well as survey response data. Univariable and multivariable analysis was used to assess predictors of improved abdominal pain after 3 months.

KEY RESULTS

180 patients with a mean age of 45.3 years were included in the final analysis. 78.3% of patients were female, and 77.2% met Rome IV criteria for irritable bowel syndrome. On multivariable analysis, improvement in constipation and diarrhea were both independent predictors of improved abdominal pain after 3 months.

CONCLUSIONS AND INFERENCES

Improvement in constipation and diarrhea both predicted improvement in abdominal pain, suggesting that addressing these factors is central to the management of abdominal pain in functional gastrointestinal disorders.

Development and Validation of the Gastrointestinal Unhelpful Thinking Scale (GUTs): A Brief Self-Report Measure for Clinical and Research Settings

This article describes the development and validation of the Gastrointestinal Unhelpful Thinking scale. The purpose of the research was to develop the Gastrointestinal Unhelpful Thinking scale to assess in tandem the primary cognitive-affective drivers of brain-gut dysregulation, gastrointestinal-specific visceral anxiety, and pain catastrophizing. The research involved 3 phases which included undergraduate and community samples. In the first phase, an exploratory factor analysis revealed a 15-item 2-factor (visceral sensitivity and pain catastrophizing) scale (N= 323), which then was confirmed in the second phase: N = 399, χ2(26) = 2.08, p = .001, Tucker-Lewis Index = 0.94, comparative fit index = 0.96, standardized root mean square residual = 0.05, and root mean square error of approximation = 0.07. Demonstrating convergent validity, Gastrointestinal Unhelpful Thinking scale total and subscales were strongly correlated with the modified Manitoba Index, Irritable Bowel Syndrome Symptom Severity Scale scores, Visceral Sensitivity Index, and the Pain Catastrophizing Scale. A third phase (N = 16) established test-retest reliability for the Gastrointestinal Unhelpful Thinking scale (total and subscales). The test-retest reliability correlation coefficient for the Gastrointestinal Unhelpful Thinking scale total score was .93 (p < .001) and for the subscales was .86 (p < .001) and .94 (p < .001), respectively. The Gastrointestinal Unhelpful Thinking scale is a brief psychometrically valid measure of visceral anxiety and pain catastrophizing that can be useful for both clinicians and researchers who wish to measure these thinking patterns and relate them to changes in gastrointestinal and psychological symptoms.

The physiological and psychological effects of cognitive behavior therapy on patients with inflammatory bowel disease before COVID-19: a systematic review

OBJECTIVE

Cognitive behavioral therapy (CBT) is now included in the treatment of patients with inflammatory bowel disease (IBD) in many settings. However, different clinical trials report different outcomes without consensus. This study aims to evaluate the impact of CBT on the mental state, quality of life and disease activity of patients with IBD.

DESIGN

Systematic review.

METHODS

This systematic review searched eligible studies from 1946 to December 8, 2019, in MEDLINE, EMBASE, CINAHL, Cochrane library, ClinicalTrials.gov, PsycINFO, Web of Science for eligible randomized controlled trials (RCT).

RESULTS

Among the initial identified 1807 references, 11 studies met inclusion criteria. CBT was shown to improve patient's quality of life and reduce the level of depression and anxiety post-intervention but was not sustained. Evidence is not enough for the effect of CBT on disease activity, or C-reactive protein level.

CONCLUSIONS

CBT has shown short-term positive psychological effects on IBD patients, but there is insufficient evidence for sustained physical and psychological improvements of IBD patients. PROSPERO registration: CRD42019152330.

The Association between Temperament, Chronotype, Depressive Symptoms, and Disease Activity among Patients with Inflammatory Bowel Disease-A Cross-Sectional Pilot Study

The psychological aspect may play an important role in ulcerative colitis (UC) and Crohn’s disease (CD). The aims of this study were to explore the differences between patients with UC and CD regarding chronotype, temperament and depression, and to assess the psychological factors mentioned as predictors of disease activity. In total, n = 37 patients with UC and n = 47 patients with CD were included in the study. They underwent a clinical assessment, including the Mayo score or Crohn Disease Activity Index (CDAI), and completed questionnaires: a sociodemographic survey, Formal Characteristics of Behavior–Temperament Inventory (FCB-TI), Chronotype Questionnaire (CQ), and the Beck Depression Index II (BDI). The Sensory Sensitivity score was higher among patients with CD than UC (p = 0.04). The emotional reactivity and endurance scores were higher among women than men with CD (p = 0.028 and p = 0.012 respectively). CQ Morningness–Eveningness (ME) correlated with Endurance (p = 0.041), Emotional Reactivity (p = 0.016), and Activity (p = 0.004). ME correlated with Rhythmicity among CD patients (p = 0.002). The Mayo score was predicted by Perseverance. The CDAI score was predicted by the BDI score. The pattern of the relationship between chronotype and temperament may differentiate patients with UC and CD. Personal disposition may play a role in the clinical assessment of patients with IBD.

Do Limited English Proficiency and Language Moderate the Relationship Between Mental Health and Pain?

AIM

To explore whether the relationship between mental health diagnosis (i.e., mood or neurotic, stress-related, or somatoform disorder) and pain is moderated by language in patients with limited English proficiency (LEP). Southeast Asian languages (i.e., Hmong, Lao, Khmer) and Spanish were compared with English.

METHOD

A retrospective data mining study was conducted (n = 79,109 visits). Pain scores, language, mental health diagnoses, age, sex, race, ethnicity, and pain diagnosis were obtained from electronic medical records. Cragg two-equation hurdle regression explored: (1) the effect of patient language and mental health diagnosis on pain and (2) the interaction between language and mental health diagnosis on pain.

RESULTS

Visits were primarily for female (62.45%), White (80.10%), not Hispanic/Latino (96.06%), and English-speaking (97.85%) patients. Spanish or Southeast Asian language increased chances of reporting any pain (i.e., pain score of 0 versus ≥1) and pain severity in visits with pain scores ≥1, whereas mental health diagnosis decreased chances of reporting any pain and pain severity. The combination of Southeast Asian language and mood disorder contributed to higher chances of reporting any pain (odds ratio [OR] = 1.78, p<.001) but no difference in severity. A similar trend was observed for Southeast Asian language and neurotic disorder (OR = 1.29, p=.143). In contrast, the combination of Spanish language and mood (p = .066) or neurotic (p = .289) disorder contributed to lower pain severity but did not change the chances of reporting any pain.

CONCLUSIONS

LEP and patient language should be considered during pain assessment within the context of mental health.

Altered Brain Structure in Chronic Visceral Pain: Specific Differences in Gray Matter Volume and Associations With Visceral Symptoms and Chronic Stress

Structural brain alterations in chronic pain conditions remain incompletely understood, especially in chronic visceral pain. Patients with chronic-inflammatory or functional bowel disorders experience recurring abdominal pain in concert with other gastrointestinal symptoms, such as altered bowel habits, which are often exacerbated by stress. Despite growing interest in the gut-brain axis and its underlying neural mechanisms in health and disease, abnormal brain morphology and possible associations with visceral symptom severity and chronic stress remain unclear. We accomplished parallelized whole-brain voxel-based morphometry analyses in two patient cohorts with chronic visceral pain, i.e., ulcerative colitis in remission and irritable bowel syndrome, and healthy individuals. In addition to analyzing changes in gray matter volume (GMV) in each patient cohort vs. age-matched healthy controls using analysis of covariance (ANCOVA), multiple regression analyses were conducted to assess correlations between GMV and symptom severity and chronic stress, respectively. ANCOVA revealed reduced GMV in frontal cortex and anterior insula in ulcerative colitis compared to healthy controls, suggesting alterations in the central autonomic and salience networks, which could however not be confirmed in supplemental analyses which rigorously accounted for group differences in the distribution of sex. In irritable bowel syndrome, more widespread differences from healthy controls were observed, comprising both decreased and increased GMV within the sensorimotor, central executive and default mode networks. Associations between visceral symptoms and GMV within frontal regions were altered in both patient groups, supporting a role of the central executive network across visceral pain conditions. Correlations with chronic stress, on the other hand, were only found for irritable bowel syndrome, encompassing numerous brain regions and networks. Together, these findings complement and expand existing brain imaging evidence in chronic visceral pain, supporting partly distinct alterations in brain morphology in patients with chronic-inflammatory and functional bowel disorders despite considerable overlap in symptoms and comorbidities. First evidence pointing to correlations with chronic stress in irritable bowel syndrome inspires future translational studies to elucidate the mechanisms underlying the interconnections of stress, visceral pain and neural mechanisms of the gut-brain axis.

Patient Strategies for Managing the Vicious Cycle of Fatigue, Pain and Urgency in Inflammatory Bowel Disease: Impact, Planning and Support

BACKGROUND

Inflammatory bowel disease (IBD) causes inter-related symptoms of fatigue, pain and urgency which can persist in remission.

AIM

To understand how people with IBD experience and self-manage these symptoms and to inform the future development of an online self-management programme.

METHODS

Using exploratory qualitative methods, we recruited participants from clinic and community settings. Focus groups, conducted across the UK, were audio-recorded and professionally transcribed. Transcripts were analysed over four rounds using framework analysis. Eight patients were consulted to agree the final structure of data and themes.

RESULTS

Seven focus groups were held; five gave useable data. Twenty-six participants (15 female; ages 21-60 years; disease duration 2-40 years) with Crohn's disease (n = 10), ulcerative colitis (n = 14) and IBD-unclassified (n = 2) attended one of these five focus groups. Three core themes emerged: The Negative Impact of Symptoms, Positively Taking Control and Seeking and Receiving Support. The persistent, often stark impact of multiple co-existing symptoms on physical and emotional wellbeing can force unwanted adjustments and limitations in working, social and intimate arenas of life. Unpredictable symptoms are challenging and impact each other in negative vicious cycles. Managing diet, pacing, accepting background levels of fatigue, pain and urgency, seeking support, exercising and attending to mental wellbeing, are all perceived as helpful in self-managing symptoms.

CONCLUSION

Fatigue, pain and urgency are troublesome for patients, especially in combination, suggesting that these should be addressed simultaneously by clinicians. Participants reported several strategies for self-management, providing patient-focused evidence to inform future development of a self-management intervention programme.

Post-inflammatory Abdominal Pain in Patients with Inflammatory Bowel Disease During Remission: A Comprehensive Review

Patients with inflammatory bowel disease often experience ongoing pain even after achieving mucosal healing (i.e., post-inflammatory pain). Factors related to the brain-gut axis, such as peripheral and central sensitization, altered sympatho-vagal balance, hypothalamic-pituitary-adrenal axis activation, and psychosocial factors, play a significant role in the development of post-inflammatory pain. A comprehensive study investigating the interaction between multiple predisposing factors, including clinical psycho-physiological phenotypes, molecular mechanisms, and multi-omics data, is still needed to fully understand the complex mechanism of post-inflammatory pain. Furthermore, current treatment options are limited and new treatments consistent with the underlying pathophysiology are needed to improve clinical outcomes.

Systematic review: Psychosocial factors of resilience in young people with inflammatory bowel disease

OBJECTIVE

Inflammatory bowel disease (IBD) affects a growing number of young people. While factors associated with poor disease experience in pediatric IBD have garnered much attention in the literature, less attention has focused on the factors associated with the resilient outcomes seen in the majority of young people with IBD. This review seeks to contribute to the literature by synthesizing research on the psychosocial factors that promote resilience in pediatric IBD and by offering future directions for the field.

METHODS

Systematic searches of the MEDLINE, Embase, PsychInfo, and CINAHL databases were performed for quantitative English-language studies with keywords for IBD, resilience or factors of resilience, and pediatric populations, with no date restrictions. Reference lists of all included articles were searched. Quality assessments were performed using an NIH tool.

RESULTS

Of 3315 articles identified, 17 were included. Studies were heterogeneous, with 19 psychosocial factors identified and analyzed for associations with over two dozen indicators of resilience. A narrative synthesis of included studies was performed. Study details were organized into three domains-individual, social, and family. Preliminary data indicate that resilience in pediatric IBD may be associated with positive body image, increased mindfulness, and improved social functioning, among other potential factors.

CONCLUSIONS

Resilience in pediatric IBD is largely unstudied. Only one study pursued an understanding of resilience as an aim, and no studies incorporated validated measures of resilience. Future prospective, theory-driven research is needed to elucidate the network of factors and mechanisms that can foster resilience in children and adolescents with IBD.

The evolution of IBD perceived engagement and care needs across the life-cycle: a scoping review

Background

The chronic and progressive evolution of Inflammatory Bowel Diseases (IBD), with its prototypical fluctuating trend, creates a condition of psycho-social discomfort, impacting the quality of life in terms of personal, working, and interpersonal.

Aims

In this article, we want to identify the nature and extent of the research evidence on the life experiences, the perceived engagement, the psychological, social care and welfare needs of people affected by IBD across the lifecycle.

Methods

Following the approach set out by Arksey and O’Malley and the PRISMA extension for scoping reviews, we conducted a scoping review in March 2019 and closed the review with an update in October 2019. It was performed using electronic databases covering Health and Life Sciences, Social Sciences and Medical Sciences, such as PubMed, Medline, Embase, Scopus, Cochrane, Web of Science, PsycInfo.

Results

We identified 95 peer-reviewed articles published from 2009 to 2019, that allowed to detection the main needs in children (psychological, need to be accepted, physical activity, feeding, parent style, support, social needs), adolescents (to understand, physical and psychological needs, protection, relational, gratitude, respect, and engagement) and adults (information, medical, psychological, social, work-related, practical, future-related, engagement). Although the literature confirms that the majority of the IBD units have planned provision for the different types of transitions, the quality and appropriateness of these services have not been assessed or audited for all the kinds of challenges across the life cycle.

Conclusions

The literature shows the relevance of organizing a flexible, personalized health care process across all the critical phases of the life cycle, providing adequate benchmarks for comparison in a multidisciplinary perspective and ensuring continuity between hospital and territory.

Biosimilar Interchangeability and Emerging Treatment Strategies for Inflammatory Bowel Diseases: A Commentary

This commentary summarizes a collection of key references published within the last ten years, and identifies pharmacologic research directions to improve treatment access and success through greater biosimilar or “follow-on” biologic utilization combined with other targeted small molecule agents that possess unique pathophysiologic mechanisms for inflammatory bowel diseases (IBD) in adult and pediatric patients. Since they are not identical to the originator or reference biologic agent, all biosimilars are not generically equivalent. However, in the US and other countries, they are considered therapeutically interchangeable if the manufacturer has demonstrated no clinically meaningful differences from the reference product. Comparisons of different clinical initiation and switching scenarios are discussed with reference to interchangeability, immunogenicity, nocebo effect, cost effectiveness, and time courses for discontinuation rates.

Exploring joint patterns of brain structure and function in inflammatory bowel diseases using multimodal data fusion

BACKGROUND

A growing number of neuroimaging studies suggest distinct neural changes in inflammatory bowel diseases (IBDs). Whether such changes may show similar spatial patterns across distinct neural features within and between specific IBD is unclear. To address this question, we used multivariate multimodal data fusion analysis to investigate structure/function modulation in remitted patients with Crohn's disease (CD) and ulcerative colitis (UC).

METHODS

Patients with IBD (n = 46; n = 31 with CD, n = 15 with UC) in stable remission and 17 healthy controls (HC) underwent structural magnetic resonance imaging (sMRI) and resting-state functional magnetic resonance imaging (rs-fMRI) as well as cognitive testing. Anxiety, depression, and fatigue were assessed using self-rating questionnaires. sMRI data were analyzed via voxel-based morphometry (VBM) and rs-fMRI data via amplitude of low-frequency fluctuations (ALFFs) and regional homogeneity (ReHo). Detection of cross-information between VBM, ALFF, and ReHo was conducted by means of a joint independent component analysis (jICA), followed by group-inference statistics.

KEY RESULTS

Joint independent component analysis detected structural alterations in middle frontal and temporal regions (VBM), and functional changes in the superior frontal gyrus (ReHo) and the medial as well as inferior frontal, inferior temporal, rectal, and subcallosal gyrus (ALFF). One joint component of extracted features of the three modalities differed significantly between IBD patients and controls (p = 0.03), and most distinctly between HC and patients with UC.

CONCLUSIONS AND INFERENCES

Using a multivariate data fusion technique, this study provides further evidence to brain alterations in IBD. The data suggest distinct neural differences between CD and UC, particularly in frontotemporal regions.

Psychological Outcomes of a Cognitive Behavioral Therapy for Youth with Inflammatory Bowel Disease: Results of the HAPPY-IBD Randomized Controlled Trial at 6- and 12-Month Follow-Up

Youth with inflammatory bowel disease (IBD) often experience psychological difficulties, such as anxiety and depression. This randomized controlled study tested whether a 3-month disease-specific cognitive behavioral therapy (CBT) in addition to standard medical care versus standard medical care only was effective in improving these youth’s psychological outcomes. As this study was aimed at prevention, we included 70 youth (10–25 years) with IBD and symptoms of subclinical anxiety and/or depression, and measured psychological outcomes at 6- and 12-month follow-up. In general, participants in both groups showed improvements in anxiety, depression, health-related quality of life, social functioning, coping, and illness perceptions, sustained until 12 months follow-up. Overall, we found no differences between those receiving additional CBT and those receiving standard medical care only. We assume that this can be explained by the perceived low burden (both somatically and psychologically) or heightened awareness of psychological difficulties and IBD. ClinicalTrials.gov NCT02265588.

Pain management in inflammatory bowel disease: feasibility of an online therapist-supported CBT-based self-management intervention

BACKGROUND

Chronic pain is a poorly managed symptom of inflammatory bowel disease (IBD). Cognitive behavioural therapy (CBT) has an evidence base in functional gastrointestinal conditions and chronic pain. This study aimed to test the feasibility and acceptability of a 9-week online facilitator-supported CBT intervention, tailored for people with chronic IBD-related pain.

DESIGN

A single-arm pre-post design with nested qualitative interviews was used. Twenty individuals with IBD and chronic pain were recruited through an online IBD charity and had consented to research in a previous survey or responded to an online charity advert. Individuals who indicated a pain-interference score of ≥ 4/10 (Brief Pain Inventory) and met inclusion criteria were invited to take part. Outcomes included recruitment and retention rates, pain interference and severity, quality of life (QoL) and psychosocial measures.

RESULTS

Of 145 individuals contacted, 55 (37.9%) responded. Two individuals were recruited from the study advertisement. Twenty out of 57 (35.1%) met screening and eligibility criteria. Eighty-five percent of the sample engaged with intervention sessions and 55% completed at least 5/9 sessions. Eighty percent of recruited participants completed the post-intervention questionnaire at week 9. The mean score for overall acceptability was 43.4 (0-70). Qualitative feedback demonstrated the value of thought monitoring and facilitator support. Scores improved for QoL and pain self-efficacy and reduced for depression, anxiety, pain catastrophising and avoidance resting behaviour.

CONCLUSIONS

Online CBT for chronic IBD-related pain appears feasible and acceptable. The study suggests positive effects for improving QoL and reducing psychological distress; however, online and face-to-face recruitment methods are recommended and establishing efficacy through larger randomised controlled trials is required.

Systematic Review: Psychosocial Correlates of Pain in Pediatric Inflammatory Bowel Disease

BACKGROUND

Pain is a common symptom in pediatric inflammatory bowel disease (IBD) and is associated with poor health outcomes, yet additional knowledge about the psychosocial correlates of pain is needed to optimize clinical care. The purpose of this study is to systematically review the psychosocial factors associated with pain and pain impact in youth diagnosed with IBD within a developmentally informed framework.

METHODS

Manual and electronic searches yielded 2641 references. Two authors conducted screening (98% agreement), and data extraction was performed in duplicate. Average study quality was rated using the National Institutes of Health Quality Assessment Tool.

RESULTS

Ten studies (N = 763 patients; N = 563 Crohn disease, N = 200 ulcerative/ indeterminate colitis) met the inclusion criteria. Findings showed consistent evidence that higher levels of child depression symptoms and child pain catastrophizing were associated with significantly greater pain and pain impact (magnitude of association ranged from small to large across studies). Greater pain and pain impact were also associated with higher levels of child anxiety symptoms, child pain threat, child pain worry, and parent pain catastrophizing. Within the included studies, female sex and disease severity were both significantly associated with pain and pain impact. Study quality was moderate on average.

CONCLUSIONS

There is evidence that child psychosocial factors are associated with pain and pain impact in pediatric IBD; more studies are needed to examine parent- and family-level psychosocial factors. Youth with IBD should be routinely screened for pain severity, pain impact, and psychosocial risk factors such as anxiety/depression.

Examining Psychosocial Mechanisms of Pain-Related Disability in Inflammatory Bowel Disease

Disability in inflammatory bowel disease (IBD) is under-investigated. Models theorize that disability is the result of a disease and its related impairments, limitations, and restrictions. This disablement process can be affected by psychosocial factors. Pain, depression, catastrophizing, and social support are associated with IBD-disability outcomes, but no studies have examined these factors concurrently. This study examined the role of psychosocial factors in the process of IBD disablement within the context of pain. Depressive symptoms, pain catastrophizing, and perceived social support were proposed as mediators in the relationship between pain and pain-related disability in cross-sectional and longitudinal models. Cross-sectionally, the mediation effects of depressive symptoms and pain catastrophizing, but not perceived social support, were significant. Longitudinally, depression was a significant mediator. Depressive symptoms and pain catastrophizing have mechanistic roles in the relationship between IBD patients' pain and pain-related disability and should be targets for intervention.

Psychological and psychosocial predictors of chronic postsurgical pain: a systematic review and meta-analysis

Knowledge about psychological and psychosocial predictors of chronic postsurgical pain is important to identify patients at risk for poor outcomes. The objective of this systematic review with meta-analysis was to assess the effect of such predictors. A comprehensive search of the available literature on this topic was performed using the electronic databases PubMed, Scopus, Embase, and PsycInfo. Estimates of the effect of each predictor were extracted, and both a narrative synthesis and a quantitative synthesis of these estimates were performed. Multiple imputation was used to take into account the effect of nonsignificant estimates in case they were not reported by original studies. From a sample of 8322 records, 83 articles were included in the narrative synthesis and 41 studies were used to perform the meta-analyses. The narrative synthesis showed that evidence about the effect of psychological predictors is heterogeneous, with few expected predictors, such as optimism, state anxiety and psychological distress, consistently associated with chronic postsurgical pain. By contrast, the meta-analyses showed that state anxiety, trait anxiety, mental health, depression, catastrophizing and, to a lesser extent, kinesiophobia and self-efficacy have a weak but significant association with chronic postsurgical pain. In conclusion, this study showed that psychological predictors have a significant association with chronic postsurgical pain and that state anxiety is the most explicative one.

Adults living with irritable bowel syndrome (IBS): A qualitative systematic review

OBJECTIVE

To consolidate existing qualitative studies which examined the experiences and needs of adults living with IBS, and to gather a holistic insight for future directions and avenues to support these adults.

METHODS

A qualitative systematic review was conducted and six databases were searched for qualitative studies, beginning from each database's inception to July 2020. The qualitative data were meta-synthesised and thematic analysis was adopted. Any discrepancies that arose were discussed between the reviewers until a consensus was reached throughout the process of data screening, selection, critical appraisal and synthesis.

RESULTS

Seventeen studies with a total of 299 adults diagnosed with IBS were included. Four themes were identified: (1) physical, psychological, and social consequences; (2) impact of IBS on working adults; (3) dealing with IBS; and (4) sources of support and support needs.

CONCLUSION

Future research across geographically diverse locations are needed to gather a thorough perspective of the experiences and needs of adults living with IBS. The development and evaluation of technology-based, trained peer-led volunteers, and interventions that adopt mindfulness, active coping strategies, cognitive behavioural therapy and acceptance, and commitment therapy are needed. Ultimately, the collaboration between the relevant stakeholders is essential for standardised instruments and materials for accurate testing, diagnosis, assessment, treatment and management of IBS.

Application of the common sense model in inflammatory bowel disease: A systematic review

BACKGROUND AND AIMS

The aim of this paper was to undertake a systematic review of the research utilizing the Common Sense Model (CSM) involving IBD cohorts to explain the psychosocial processes, including illness perceptions and coping styles, that underpin patient reported outcomes (PROs) - psychological distress (PD) and quality of life (QoL).

METHODS

Adult studies were identified through systematic searches of 8 bibliographic databases run in August 2020 including Medline, Embase, and PsychINFO. No language or year limits were applied.

RESULTS

Of 848 records identified, 516 were selected with seven studies evaluating the CSM mediating pathways for final review (n = 918 adult participants). Consistent with the CSM, illness perceptions were associated with PD and QoL in six and five studies respectively. Illness perceptions acted as mediators, at least partially, on the relationship between IBD disease activity and PD and/or QoL in all seven studies. Coping styles, predominantly maladaptive-based coping styles, were found to act as mediators between illness perceptions and PD and/or QoL in five studies. Perceived stress was identified in one study as an additional psychosocial process that partially explained the positive influence of illness perceptions on PD, and a negative impact on QoL. Five studies were classified as high quality and two as moderate.

CONCLUSIONS

The CSM can be utilised in IBD cohorts to evaluate key psychosocial processes that influence PROs. Future research should explore additional psychosocial processes within the CSM and evaluate the efficacy of targeting CSM processes to promote psychological well-being and QoL in IBD cohorts.

One-year risk of opioid use disorder after index hospitalization for inflammatory bowel disease

PURPOSE

Patients with inflammatory bowel disease are commonly prescribed opiates for pain. We sought to determine the incidence of opiate use disorder after inflammatory bowel disease (IBD) admission over a 1-year period as well as its impact on mortality and hospital resource utilization.

METHODS

The Nationwide Readmission Database 2016 was used to identify adult patients with a principal diagnosis of IBD who were subsequently readmitted with a primary diagnosis of opioid use disorder. The primary outcome was 1-year readmission rate for opiate use disorder. Predictors were analyzed using multivariate logistic regression. Secondary outcomes were mortality rate, length of stay, and total hospital costs and charges.

RESULTS

Among the 6340 index hospitalizations for IBD, 4.7% (6.0% Crohn's and 2.6% ulcerative colitis) were readmitted within 1 year for opiate use disorder. Readmission hospitalizations were associated with additional mortality (0.32%) and hospital utilization (length of stay 4.80 days, mean total costs $9503, and mean total charges $38,288). Ulcerative colitis had significantly higher mortality and hospital utilization costs compared with Crohn's disease. In multivariable analysis, odds of readmission were associated with female sex (OR 1.51, CI 1.19-1.92), private insurance (OR 0.20, CI 0.11-0.37), Charlson Comorbidity Index (OR 0.20, CI 0.11-0.37), anxiety (OR 1.65, CI 1.02-2.63), and depression (OR 2.07, CI 1.28-3.34). On stratification analysis, psychiatric comorbidities were associated with both Crohn's and ulcerative colitis.

CONCLUSION

Patients with IBD were often readmitted for opiate use disorder and sustained significant mortality and hospital costs. Psychiatric comorbidities, gender, and insurance status impacted the odds of readmission and represent targets for intervention.

Anxiety, depression, chronic inflammation and aortic stiffness in Crohn's disease: the brain--gut--vascular axis

BACKGROUND

Patients with Crohn's disease have an increased aortic stiffness, a known cardiovascular risk factor. Anxiety, a key factor of the brain--gut axis in patients with Crohn's disease, is implicated in the pathogenesis and progression of the disease, and is linked with aortic stiffening in other clinical settings.

OBJECTIVES

Considering that depression is frequently linked to anxiety in Crohn's disease, we performed a mediation analysis to reveal the potential link between anxiety, depression and aortic stiffness in these patients.

METHODS

Multicentre observational cross-sectional study of 86 consecutive patients with Crohn's disease and 86 matched control individuals. The connections between anxiety, depression, disease duration, aortic pulse wave velocity (aPWV), brachial and central SBP were tested using partial least squares structural equations modelling.

RESULTS

In patients with Crohn's disease, anxiety (path coefficient: 0.220, P = 0.01) and disease duration (path coefficient: 0.270, P = 0.02) were associated with aPWV that in turn was associated with brachial SBP (path coefficient: 0.184, P = 0.03). These associations were even stronger in patients with active disease. The connection between anxiety and aPWV was in part mediated by central SBP (indirect effect: 0.090, P = 0.01; indirect-to-total effect ratio: 41%) as well as, in a pilot substudy, by sympathetic hyperactivity. Anxiety and depression were highly correlated in patients with Crohn's disease. Consequently, results were confirmed when anxiety was substituted by depression.

CONCLUSION

The connections of anxiety, depression and chronic inflammation with aPWV and SBP could suggest the first evidence of a brain--gut--vascular axis and new potential targets for therapy in patients with Crohn's disease.

Elucidating vulnerability to inflammation-induced hyperalgesia: Predictors of increased musculoskeletal pain sensitivity during experimental endotoxemia

Despite broad clinical implications, the mechanisms linking inflammation and pain remain incompletely understood. Using human experimental endotoxemia as a translational model of systemic inflammation, we aimed to elucidate putative vulnerability factors of inflammation-induced musculoskeletal hyperalgesia. We pooled data from three published randomized controlled trials, resulting in a sample of N = 98 healthy volunteers who received either low-dose endotoxin (lipopolysaccharide) or vehicle (saline) intravenously. As measure of musculoskeletal pain sensitivity, pressure pain thresholds (PPTs) were assessed at baseline and 3 h post injection with a handheld algometer for the low back (erector spinae muscle), calf (gastrocnemius muscle), and shoulder region (deltoid muscle). Implementing multiple regression models, we tested the contribution of putative vulnerability factors on musculoskeletal hyperalgesia during systemic inflammation, including acute changes in pro-inflammatory cytokines, state anxiety and mood, as well as pre-existing symptoms of anxiety and depression. Endotoxin application led to significant increases in plasma cytokines, state anxiety, and negative mood, and significantly decreased PPTs for all muscle groups. Regression models revealed that greater M. erector spinae PPT changes were predicted by higher HADS-anxiety scores. Higher TNF-α concentration emerged as predictor for M. gastrocnemius PPT changes, and more pronounced TNF-α increase and higher HADS-anxiety were predictive for M. deltoideus PPTs. HADS scores emerged as predictor for a mean PPT score (computed across all body sites). Together, our results indicate that musculoskeletal hyperalgesia during systemic inflammation is related to pro-inflammatory cytokines, specifically TNF-α. Importantly, subclinical anxiety symptoms (even though in a low and normal range in this cohort of healthy volunteers) may contribute to inflammation-induced hyperalgesia, making individuals more vulnerable to the detrimental effects of systemic inflammation.

Pain in Inflammatory Bowel Disease Is Not Improved During Hospitalization: The Impact of Opioids on Pain and Healthcare Utilization

BACKGROUND

Most patients with IBD experience pain, especially during acute disease exacerbations. Opioid use continues to be more prevalent in IBD than any other chronic gastrointestinal condition, and the majority of IBD patients consume narcotics during hospitalization despite the risks of infection and death.

METHODS

We performed a retrospective review of 57 subjects aimed at quantifying pain and opiate consumption for IBD-related admissions over a 3-month period. For each patient, the average and maximum of each day's pain scores were used to measure changes in pain from admission to discharge using mixed model regression, with opiate use as a time-dependent covariate.

RESULTS

The daily average pain score over the entire hospitalization was 4.23 ± 2.09, and the maximum pain score was 8.28 ± 1.75. Among opioid users (n = 51), the daily average pain score was 4.65 ± 2.16 and the maximum pain score was 7.53 ± 2.56. Across all cases from admission to discharge, there was less than a 1-point change in daily average pain (- 0.96 ± 2.03, p = 0.0009), and no change in maximum pain (- 0.89 ± 3.59, p = 0.0671). Opioid users, a subset of the overall cohort, had a similar less than one-point drop in daily average pain (- 0.94 ± - 0.29, p = 0.0024) and no change in daily maximum pain scores (- 0.81 ± - 0.47, p = 0.0914). Patients on average used 20 ± 25 mg morphine equivalents per day. Opioid-naïve patients used similar doses to those who used opioids prior to admission (PTA). Almost half of all cases (47%) were discharged with an opioid prescription, the majority (71%) of whom were not on opioids PTA.

CONCLUSIONS

Pain in IBD is not well controlled through hospitalization, with less than a 1-point change from admission to discharge, despite significant opioid consumption. Alternative analgesic methods should be explored, given the significant impact of narcotics on long-term outcomes including mortality and quality of life.
