There has been a dramatic rise in mental health difficulties during the coronavirus disease 2019 (COVID-19) pandemic. While young adults have the lowest risk of hospitalization and mortality due to COVID-19, they have been identified as being at highest risk of detrimental mental health outcomes during the pandemic, along with women, those with lower socioeconomic status and those with pre-existing mental health conditions. Somewhat of a crisis in mental health has emerged across the general population through the evolution of the pandemic. A national Canadian survey identified a quadrupling of those experiencing pervasive elevated anxiety symptoms early in the pandemic compared to pre-pandemic levels, and a doubling of those with pervasive elevated depressive symptoms. Independent of the pandemic, persons with inflammatory bowel disease (IBD) can face multiple challenges related to their disease, which can result in a significant psychosocial burden and psychologic distress. Anxiety and depression have been found to be more prevalent in persons with IBD. Many potential factors contribute to the increased psychologic distress and negative impacts on mental health of the COVID-19 pandemic on persons with IBD. These include the fears of contracting COVID-19 or infecting other people. Many believe that IBD or its treatments predispose them to an increased risk of COVID-19 or a worse outcome if acquired. Concerns about access to health care add to mental distress. People with IBD generally report lower quality of life (QOL) compared to community controls. Psychologic interventions, in addition to adequate disease control, have been shown to improve health-related QOL. Uncertainty is another factor associated with reduced health-related QOL. Most studies suggest that persons with IBD have suffered QOL impairment during the pandemic in comparison to the pre-pandemic period. Uncertainties brought on by the pandemic are important contributors for some of the reduction in QOL.

OBJECTIVE To determine whether childhood maltreatment is associated with immune-mediated inflammatory disorders (IMID; multiple sclerosis [MS], inflammatory bowel disease [IBD] and rheumatoid arthritis [RA]). We further aimed to determine the relationship between maltreatment and psychiatric comorbidity in IMID and whether these relationships differed across IMID. METHODS 681 participants (MS: 232, IBD: 216, RA: 130, healthy controls: 103) completed a structured psychiatric interview to identify psychiatric disorders, and the Childhood Trauma Questionnaire to evaluate five types of maltreatment: emotional abuse, physical abuse, sexual abuse, emotional neglect and physical neglect. We evaluated associations between maltreatment, IMID and psychiatric comorbidity using multivariable logistic regression models. RESULTS The prevalence of having ≥1 maltreatment was similar across IMID, but higher than in controls (MS: 63.8%, IBD: 61.6%, RA: 62.3%, healthy controls: 45.6%). Emotional abuse was associated with having an IMID (adjusted odds ratio [aOR] 2.37; 1.15-4.89). In the sex-specific analysis, this association was only present in women. History of childhood maltreatment was associated with a lifetime diagnosis of a psychiatric disorder in the IMID cohort (OR 2.24; 1.58-3.16), but this association did not differ across diseases. In those with IMID, total types of maltreatments (aOR 1.36; 1.17-1.59) and emotional abuse (aOR 2.64; 1.66-4.21) were associated with psychiatric comorbidity. CONCLUSIONS Childhood maltreatment is more common in IMID than in a healthy population, and is associated with psychiatric comorbidity. Given the high burden of psychiatric disorders in the IMID population, clinicians should be aware of the contribution of maltreatment and the potential need for trauma-informed care strategies.

This study aimed to explore the association between perceived isolation and symptoms of distress in people with GI disorders at the time of the pandemic; and to examine factors which moderate this relationship. This online cross-sectional survey was advertised in May–September 2020 via patient organisations and associated social media. Overall, 831 people (82% female, mean age 49 years) from 27 countries participated. A significant relationship between social isolation and psychological distress was noted (r = .525, p

OBJECTIVE In this study, we aimed to determine the lifetime prevalence of substance use disorder (SUD) in a Canadian rheumatoid arthritis (RA) cohort and factors associated with SUD in RA. METHODS Participants with RA (N = 154) were recruited via rheumatology clinics as part of a larger cohort study of psychiatric comorbidity in immune-mediated inflammatory diseases. SUD is defined as the uncontrolled use of a substance despite the harmful consequences of its use. To identify lifetime SUD, the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition was administered to participants. Participants' sociodemographic and RA clinical characteristics were also assessed. We examined factors associated with lifetime SUD using unadjusted and adjusted logistic regression modeling. RESULTS Twenty-three (14.9%) of 154 participants with RA met the criteria for a lifetime diagnosis of SUD. The majority of the participants were women, were White, had postsecondary education, and were on a disease-modifying antirheumatic drug. Factors associated with increased odds of SUD were male sex (adjusted odds ratio [aOR]: 3.63, 95% confidence interval [CI]: 1.03-12.73), younger age (aOR: 0.94, 95% CI: 0.90-0.98), and ever smoking (aOR: 6.44, 95% CI: 1.53-27.07). CONCLUSION We found that approximately 1 in 7 individuals with RA had a lifetime diagnosis of SUD, highlighting the importance of identifying and treating SUD in those with RA. In particular, the following factors were associated with higher odds of SUD: male sex, younger age, and smoking behaviors.

Background: Reports of cognitive impairment in inflammatory bowel disease (IBD) have been mixed. IBD and cardiovascular disease are often co-morbid, yet it remains unknown whether vascular comorbidity confers a risk for decreased cognitive functioning, as observed in other populations. Methods: Participants with IBD were recruited from a longitudinal study of immune-mediated disease. Participants were administered a standardized neuropsychological test protocol, evaluating information processing speed, verbal learning and memory, visual learning and memory, and verbal fluency/executive function. Cognitive test scores were standardized using local regression-based norms, adjusting for age, sex, and education. Vascular risk was calculated using a modified Framingham Risk Score (FRS). We tested the association between FRS and cognitive test scores using a quantile regression model, adjusting for IBD type. Results: Of 84 IBD participants, 54 had ulcerative colitis and 30 had Crohn’s disease; mean (SD) age was 53.36 (13.95) years, and a high proportion were females (n = 58). As the risk score (FRS) increased, participants demonstrated lower performance in information processing speed (β=-0.12; 95% CI: -0.24, -0.006) and verbal learning (β=-0.14; 95% CI: -0.28, -0.01) at the 50th percentile. After adjusting for IBD type, higher FRS remained associated with lower information processing speed (β=-0.13; 95% CI: -0.24, -0.03). Conclusion: Vascular comorbidity is associated with lower cognitive functioning in persons with IBD, particularly in the areas of information processing speed and verbal learning. These findings suggest that prevention, identification, and treatment of vascular comorbidity in IBD may play a critical role for improving functional outcomes in IBD.

The Comorbidity and Cognition in Multiple Sclerosis (CCOMS) study represents a coordinated effort by a team of clinicians, neuropsychologists, and neuroimaging experts to investigate the neural basis of cognitive changes and their association with comorbidities among persons with multiple sclerosis (MS). The objectives are to determine the relationships among psychiatric (e.g., depression or anxiety) and vascular (e.g., diabetes, hypertension, etc.) comorbidities, cognitive performance, and MRI measures of brain structure and function, including changes over time. Because neuroimaging forms the basis for several investigations of specific neural correlates that will be reported in future publications, the goal of the current manuscript is to briefly review the CCOMS study design and baseline characteristics for participants enrolled in the three study cohorts (MS, psychiatric control, and healthy control), and provide a detailed description of the MRI hardware, neuroimaging acquisition parameters, and image processing pipelines for the volumetric, microstructural, functional, and perfusion MRI data.

The Inflammatory Bowel Disease Symptom Inventory (IBDSI) is a validated patient self-reported measure used to assess IBD disease activity. There have yet to be more granular analyses on which symptoms are most associated with active disease.To assess the prevalence of symptoms, and to examine which are most associated with disease activity as measured by a symptom index and objective measure of inflammation METHODS: The Manitoba Living with IBD Study is a prospective study of 156 participants with confirmed IBD who completed bi-weekly IBDSI. Relative risks (RR) and predictive values (NPV and PPV) were reported for each symptom to predict active disease defined as active IBDSI, self-reported flare and elevated faecal calprotectin (FCAL) (250 μg/g). Analyses were undertaken following stratification based on sex, and disease type (Crohn's disease [CD] and ulcerative colitis [UC]).In total, 69.2% were female; 64.7% had CD. Fatigue was the most prevalent symptom in both inactive and active disease, across all three disease measures (IBDSI: 24.5% and 75.1%, self-reported flare: 42.2% and 72.2%, FCAL: 46.0% and 60.6%). The absence of fatigue had a high NPV for active IBDSI and self-reporting a flare in both CD and UC. Urgency had a consistently strong NPV and RR across all three disease measures in both IBD subtypes and sexes. The number of loose/liquid bowel movements predicted elevated FCAL in UC (RR males = 3.5, 95% CI 1.2-9.9, RR females = 1.8, 95% CI 1.2-2.7), as did blood in stool in UC females (RR = 1.8, 95% CI 1.2-2.7). In males with CD, excessive bowel gas (RR = 2.0, 95% CI 1.2-3.4) and urgency (RR = 3.9, 95% CI 1.6-9.3) best predicted an elevated FCAL. No symptom was strongly predictive of an elevated FCAL in CD females.Urgency was consistently associated with disease activity, irrespective of the disease measure. Fatigue was the most prevalent symptom irrespective of disease activity measure. Individual symptoms have different impacts on subjective (IBDSI) and objective (FCAL) measures in IBD.

We estimated the incidence and prevalence of benzodiazepine and Z-drug (separately and jointly as BZD) use in the inflammatory bowel disease (IBD) population compared with matched controls without IBD and examined the association of mood/anxiety disorders (M/ADs) with the use of BZD from 1997 to 2017.Using administrative data from Manitoba, Canada, we identified 5,741 persons with incident IBD who were matched in a 1:5 ratio to controls on sex, birth year, and region. Validated case definitions were used to identify M/AD. Dispensations of BZD were identified. Multivariable generalized linear models were used to assess the association between IBD, M/AD, and BZD use.In 2016, the incident age/sex-standardized benzodiazepine use rates per 1,000 were 28.06 (95% confidence interval [CI] 26.41-29.81) in the IBD cohort and 16.83 (95% CI 16.28-17.39) in controls (adjusted rate ratio = 1.69 [95% CI 1.56-1.79]). Benzodiazepine incidence rates were higher for women with IBD than men, but the RR between cases and controls were similar for men and women. The incident age/sex-standardized Z-drug use rate per 1,000 was 21.07 (95% CI 19.69-22.41) in the IBD cohort. This was 1.87-fold higher than in controls (95% CI 1.73-2.01). In 2017, approximately 20% of persons with IBD used benzodiazepines and 20% used Z-drugs. There was a subadditive effect of both benzodiazepine and Z-drug uses between IBD and M/AD after adjusting for covariates.The use of BZD is more common in people with IBD than in population controls. Strategies to reduce the use of BZDs in persons with IBD and to offer alternative management strategies for M/ADs, sleep disorders, and other symptomatic concerns are needed.

Inflammatory bowel disease (IBD) is associated with significant psychological comorbidities, with associated impacts on patient quality of life, disease course, and health care costs. The present article reviews the latest evidence on the etiology of psychological comorbidities in IBD, with a focus on shared inflammatory pathways. The current state of practice in managing and understanding psychological comorbidities from the perspective of both gastroenterology practice and psychological treatment is reviewed, with a focus on evidence-based treatments shown to be effective in managing depression, anxiety, stress, and improving IBD-related health outcomes.

BACKGROUND: A major deficit in understanding and improving treatment in coeliac disease (CD) is the lack of empiric data on real world gluten exposure. AIMS: To estimate gluten exposure on a gluten-free diet (GFD) using immunoassays for gluten immunogenic peptides (GIP). Relationships among GIP detection, symptoms and suspected gluten exposures were examined. METHODS: Adults with biopsy-confirmed CD on a GFD for 24 months were recruited from a population-based inception cohort. Participants kept a diary and collected urine samples for 10 days and stools on days 4–10. “Doggie bags” containing ¼ portions of foods consumed were saved during the first 7 days. Gluten in food, stool and urine was quantified using A1/G12 ELISA. RESULTS: Eighteen participants with CD (12 female; age 21–70 years) and 3 participants on a gluten-containing diet enrolled and completed the study. 12/18 CD participants had a median 2.1 mg gluten per exposure (range 0.2 to >80 mg). Most exposures were asymptomatic and unsuspected. There was high intraindividual variability in the interval between gluten ingestion and excretion. Participants were generally unable to identify the food. CONCLUSIONS: Gluten exposure on a GFD is common, intermittent, usually silent, and excretion kinetics are highly variable between individuals. The amount of gluten varied widely, but was typically in the milligram range which was 10–100 times less than was consumed by those on an unrestricted diet. These findings suggest that a strictly gluten free diet is difficult to attain and specific exposures are difficult to detect due to variable time course of excretion.

Background: Longitudinal studies assessing depression and anxiety effects on cognition in multiple sclerosis (MS) are limited. Objective: We tested whether within-person fluctuations in symptoms of depression or anxiety over time affect cognition in persons with MS, inflammatory bowel disease (IBD), rheumatoid arthritis (RA), and a lifetime history of depression/anxiety disorders (DEP/ANX) but without an immune-mediated inflammatory diseases (IMID). Methods: We followed participants (MS: 255, IBD: 247, RA: 154, and DEP/ANX: 306) for 3 years. Annually, they completed the hospital anxiety and depression scale (HADS) and cognitive tests including the symbol digit modalities test (SDMT). We evaluated associations of elevated symptoms (scores ⩾ 11) of anxiety (HADS-A) and depression (HADS-D) with SDMT z-scores using multivariable linear models—estimating between-person and within-person effects. Results: Participants with MS performed worse on the SDMT than participants in the DEP/ANX cohort (β = −0.68; 95% CI: −0.88, −0.48). Participants with elevated HADS-A scores performed worse on the SDMT than those without elevated scores (β = −0.43; 95% CI: −0.65, −0.21), particularly those with RA. Time-varying within-person elevations in depressive symptoms were associated with worse SDMT performance (β = −0.12; 95% CI: −0.21, −0.021). Conclusions: Across persons, elevated symptoms of anxiety adversely affected information processing. Elevated symptoms of depression within-persons over time were associated with declines in information processing speed.

To develop group-based trajectories of depressive symptoms in immune-mediated inflammatory disease (IMID) to understand their evolution and identify any associated factors, with the overall goal of identifying those at highest risk of higher depressive symptom burden.922 participants had an IMID or anxiety/depression. The PHQ-9 was administered at four visits, and polygenic risk scores (PRS) for major depressive disorder, depressive symptoms, and body mass index (BMI) were generated. Group-based trajectory modelling of PHQ-9 scores estimated distinct trajectories. Regression tested whether specific factors were associated with the trajectories. Mediation analyses assessed whether IMID mediated the association between BMI PRS and trajectories.Three trajectories were identified. Regression demonstrated those in Group 3 ('high symptoms') had significantly higher PRS for the three traits, compared to Group 1 ('minimal symptoms') (OR: 1.34-1.66, P 0.01). Stratified analyses in the IMID subgroup revealed an increased effect for BMI PRS in Group 3 (OR: 2.31, P 0.001), in contrast, BMI PRS was no longer associated in the non-IMID sample. No significant indirect effect of BMI PRS on depressive symptoms trajectories was identified via IMID.A significant association between polygenicity and PHQ-9 trajectories supports a role for genetic inheritance in the variability in depressive symptoms in IMID.

The aim of this cross-sectional study was to use an extended common sense model (CSM) to evaluate the impact of fear of COVID-19 on quality of life (QoL) in an international inflammatory bowel disease cohort. An online study involving 319 adults (75% female, mean (SD) 14.06 (15.57) years of symptoms) completed the Gastrointestinal Symptom Rating Scale, Brief Illness Perceptions Questionnaire, Fear of Contracting COVID-19 Scale, Brief-COPE, Depression, Anxiety and Stress Scale, and the EUROHIS-QOL. The extended CSM had an excellent fit (χ

Objective The COVID-19 pandemic has had a significant impact on mental health across the globe. People living with a chronic gastrointestinal (GI) disorder might be particularly at risk of mental health complications given higher rates of comorbid anxiety and depression compared to the healthy population. As GI disorders affect up to 40% of the population worldwide, this international collaborative study seeks to evaluate the extent of the impact of the COVID-19 pandemic on GI symptoms specifically and more generally on the well-being of those living with chronic GI conditions. Methods A longitudinal survey with three time points (baseline, 6-month, and 12-month) will be conducted online. Adult participants with GI disorders from multiple countries will be recruited via patient associations, social media advertising, utilizing snowball sampling. Participants will be invited to complete a battery of questionnaires including demographic and health parameters, and measures of gastrointestinal symptoms, fear of COVID-19, perceived impact of COVID-19, illness perceptions, coping, depression, anxiety, stress, catastrophizing, and quality of life, using validated measures where available. Statistical analyses will include univariate descriptive models, multivariate models utilizing regression, mediation, and moderation, and latent growth models. Conclusions This project may present novel information to the field of psychogastroenterology and may provide crucial information regarding the areas of impact for individuals with GI disorders during and following the pandemic. Further, this information can guide healthcare providers and patient associations on how to target support related to the pandemic mental health sequelae for these patients.

Goal The aim of this study was to survey adults with celiac disease (CD) on the utility of specific aspects of follow-up and on information needs. Background Currently, the treatment for CD is strict gluten avoidance. Although this places the onus on the patient for disease management, patient perspectives on CD care have not been formally assessed. Study The Manitoba Celiac Disease Cohort prospectively enrolled adults newly diagnosed with CD using serology and histology. At the 24-month study visits, participants rated the utility of aspects of CD care on a 5-point scale anchored by "not at all useful" and "very useful" and the helpfulness of information on CD-related topics on a 6-point scale anchored by "not at all helpful" and "very helpful." Results The online survey was completed by 149 of 211 cohort members [median age 40 (interquartile range 30 to 56) y; 68% female]. Adherence to a gluten-free diet was good. Most participants (87%) responded that they should be seen regularly for medical follow-up of CD, preferably every 6 (26%) or 12 months (48%). Blood tests were the most highly rated care component (rated scored ≥4/5 by 78% of respondents), followed by the opportunity to ask about vitamins and supplements (50%), symptom review (47%), and information on CD research (44%). Diet review was not considered helpful. Conclusions Two years after diagnosis, most individuals with CD find regular specialist follow-up helpful, particularly for biochemical assessment of disease activity and its complications. Furthermore, information on research and long-term complications of CD is also valued.

Positive and negative psychological attributes have been shown to influence disease outcomes in many chronic health conditions. We aimed to evaluate the association between self-efficacy, optimism, health anxiety and intolerance of uncertainty and disease activity in inflammatory bowel disease (IBD).Adults with confirmed and recently active IBD enrolled in a prospective cohort study. Demographics, disease information, validated measures of psychological functioning related to general self-efficacy, optimism, health anxiety and intolerance of uncertainty were collected at baseline, week 26 and week 52. Clinical disease activity was assessed using the Inflammatory Bowel Disease Symptom Inventory (IBDSI), self-reported flares, and intestinal inflammation using fecal calprotectin (FCAL), collected at baseline, weeks 26 and 52. Generalized estimating equations were used to test the association between psychological functioning and disease activity.Participants' (n = 154) mean age was 43.4 years (SD 12.5), 69.5% were women and 64.1% had Crohn's disease. Adjusting for demographic variables, higher self-efficacy was associated with lower likelihood of flare by self-report (odds ratio [OR] 0.80, 95% confidence interval [CI] 0.71, 0.91) and IBDSI (OR 0.89, 95% CI 0.80, 0.99), while higher health anxiety was associated with greater likelihood of flare by self-report (OR 1.07, 95% CI 1.01, 1.18) and higher symptomatic disease activity (IBDSI; OR 1.14, 95% CI 1.05, 1.24). The psychological attributes were not significantly associated with active disease as measured by inflammation (FCAL).General self-efficacy and health anxiety are relevant in understanding patient experience with disease activity, and may be appropriate targets for psychological intervention in the care of individuals with IBD.

Persons with inflammatory bowel disease (IBD) make up more than 0.75% of the Canadian population in 2021. Early in the COVID-19 pandemic, individuals with IBD, particularly those on immunosuppressive therapies, were concerned that their health status may place them at higher risk of contracting COVID-19 or experiencing more severe disease course if infected with SARS-CoV-2. In response, Crohn’s and Colitis Canada developed the COVID-19 and IBD Taskforce in March 2020 to rapidly synthesize the evolving knowledge of COVID-19 as relevant to Canadians with IBD. The Taskforce communicated expert information directly to the Canadian IBD community through online tools and a webinar series. In order to understand the full impact of COVID-19 on the IBD community, Crohn’s and Colitis Canada commissioned a policy report that was informed through a systematic literature review and synthesized across working groups along the following domains: Epidemiology, Children and Expectant Mothers with IBD, Seniors with IBD, Mental Health, Risk Factors and Medications, Vaccines, and Healthcare Delivery during the Pandemic and the Future Model of IBD Care. This report from Canadian physicians, researchers, and IBD community representatives highlights the physical, mental, and health systems impact of COVID-19 on the entire spectrum of the IBD community, including children, adolescents, adults, seniors, and pregnant people with IBD. This executive summary provides an overview of the crucial information from each of the chapters of the policy report, supplemented with additional information made available through Crohn’s and Colitis Canada’s webinar-based knowledge translation platform.

Objective We assessed the information needs of persons with any of three immune-mediated inflammatory diseases (multiple sclerosis [ MS], inflammatory bowel disease [IBD] and rheumatoid arthritis [RA]) regarding depression, as a first step toward developing patient-relevant information resources, ultimately to facilitate self-management and appropriate care. We also compared information needs across genders. Methods We surveyed participants with MS, IBD and RA regarding depression-related information needs including types of treatments, effectiveness, risks, benefits, and perceived helpfulness of treatments. We compared responses between groups using multivariate regression. Results 328 participants provided complete responses (MS: 141, IBD: 114, RA: 73). Most of the topics queried were perceived as very important, and similarly important for all groups. Women placed higher importance than men on most topics. The most popular formats for receiving information were discussion with a counselor (very preferred: 67.4%) and written information (very preferred: 65.5%); this did not differ between groups. Conclusions Persons affected by MS, IBD and RA are interested in receiving information about multiple topics related to depression treatment, from multiple sources. Women desire more information than men. Practice implications These findings can be used to design information resources to meet information needs regarding depression in MS, IBD and RA.

Objectives Existing measures of inflammatory bowel disease (IBD) symptoms are not well suited to self-report, inadequate in measurement properties, insufficiently specific, or burdensome for brief or repeated administration. We aimed to develop a patient-reported outcome measure to assess a broader range of IBD symptoms. Methods The IBD Symptoms Inventory (IBDSI) was developed by adapting symptom items from existing clinician-rated or diary-format inventories; after factor analysis, 38 items were retained on 5 subscales: bowel symptoms, abdominal discomfort, fatigue, bowel complications, and systemic complications. Participants completed the IBDSI and other self-report measures during a clinic visit. A nurse administered the Harvey Bradshaw Index (HBI) for Crohn’s disease (CD) or the Powell-Tuck Index (PTI) for ulcerative colitis (UC), and a gastroenterologist completed a global assessment of disease severity (PGA). Results The 267 participants with CD (n = 142) or UC (n = 125), ages 18 to 81 (M = 43.4, SD = 14.6) were 58.1% female, with a mean disease duration of 13.9 (SD = 10.5) years. Confirmatory factor analysis supported the 5 subscales. The total scale and subscales showed good reliability and significant correlations with self-report symptom and IBD quality of life measures, the HBI, PTI, and PGA. Conclusions The IBDSI showed strong measurement properties: a supported factor structure, very good internal consistency, convergent validity, and excellent sensitivity and specificity to clinician-rated active disease. Self-report HBI and PTI items, when extracted from this measure, produced scores comparable to clinician-administered versions. The 38-item IBDSI, or 26-item short form, can be used as a brief survey of common IBD symptoms in clinic or research settings.

ObjectiveTo determine whether anxiety and depression are associated with cognition in multiple sclerosis (MS), and whether these associations are similar in other immune-mediated inflammatory diseases (IMID; including inflammatory bowel disease [IBD] and rheumatoid arthritis [RA]) and in anxious/depressed individuals (ANX/DEP) without an IMID.MethodsParticipants (MS: n = 255; IBD: n = 247; RA: n = 154; ANX/DEP: n = 308) completed a structured psychiatric interview, the Hospital Anxiety and Depression Scale, and cognitive testing, including the Symbol Digit Modalities Test, the California Verbal Learning Test, and Letter Number Sequencing test. Test scores were converted to age-, sex-, and education-adjusted z scores. We evaluated associations of anxiety and depression with the cognitive z scores using multivariate linear models, adjusting for disease cohort.ResultsAll cohorts exhibited higher rates of impairment (i.e., z less than or equal to −1.5) in the domains of processing speed, verbal learning, and delayed recall memory relative to general population norms. Higher levels of anxiety symptoms were associated with slower processing speed, lower verbal learning, and lower working memory performance (all p < 0.001); higher levels of depression symptoms were associated with slower processing speed. These associations did not differ across cohorts.ConclusionAnxiety and depression are associated with lower cognitive function in MS, with a similar pattern observed in persons with other IMID, including IBD and RA, and persons without an IMID. Managing symptoms of anxiety and of depression in MS, as well as other IMIDs, is important to mitigate their effect on cognition.

Objective To determine whether comorbid diabetes and hypertension are associated with cognition in multiple sclerosis (MS) after accounting for psychiatric comorbidities. Methods Participants completed a structured psychiatric interview, the Hospital Anxiety and Depression Scale (HADS), a comorbidity questionnaire, and cognitive testing including the Symbol Digit Modalities Test (SDMT), California Verbal Learning Test (CVLT-II), Brief Visuospatial Memory Test-Revised (BVMT-R), and verbal fluency. Test scores were converted to age-, sex- and education-adjusted z-scores. We evaluated associations between diabetes and hypertension and the four cognitive z-scores using a multivariate linear model, adjusting for comorbid depression and anxiety disorders, psychotropic medications, disease-modifying therapies, smoking status and body mass index. Results Of 111 participants, most were women (82.9%) with relapsing remitting MS (83.5%), of mean (SD) age 49.6 (12.7) years. Comorbidity was common; 22.7% participants had hypertension, 10.8% had diabetes, 9.9% had current major depression, and 9.9% had current anxiety disorders. Mean (SD) z-scores were: SDMT −0.66 (1.15), CVLT-II −0.43 (1.32), BVMT-R −0.49 (1.07) and fluency −0.59 (0.86). Diabetes (p = 0.02) and anxiety disorder (p = 0.02) were associated with cognitive function overall. Diabetes was associated with lower BVMT-R (β = −1.18, p = 0.0015) and fluency (β = −0.63, p = 0.037) z-scores. Anxiety was associated with lower SDMT (β = -1.07, p = 0.0074) z-scores. Elevated anxiety symptoms (HADS-A ≥ 11) were associated with lower z-scores on the SDMT and CVLT-II. Conclusion Comorbidities, including diabetes and anxiety, are associated with cognitive dysfunction in MS. Their presence may contribute to the heterogeneous pattern of impairments seen across individuals and they may represent targets for improved management of cognitive symptoms.

Background & aims Irritable bowel syndrome (IBS) is one of the most common gastrointestinal (GI) disorders, affecting about 10% of the general population globally. The aim of this consensus was to develop guidelines for the management of IBS. Methods A systematic literature search identified studies on the management of IBS. The quality of evidence and strength of recommendations were rated according to the Grading of Recommendation Assessment, Development and Evaluation (GRADE) approach. Statements were developed through an iterative online platform and then finalized and voted on by a multidisciplinary group of clinicians and a patient. Results Consensus was reached on 28 of 31 statements. Irritable bowel syndrome is diagnosed based on symptoms; serological testing is suggested to exclude celiac disease, but routine testing for C-reactive protein (CRP), fecal calprotectin or food allergies is not recommended. A trial of a low fermentable oligosaccharides, disaccharides, monosaccharides, polyols (FODMAP) diet is suggested, while a gluten-free diet is not. Psyllium, but not wheat bran, supplementation may help reduce symptoms. Alternative therapies such as peppermint oil and probiotics are suggested, while herbal therapies and acupuncture are not. Cognitive behavioural therapy and hypnotherapy are suggested psychological therapies. Among the suggested or recommended pharmacological therapies are antispasmodics, certain antidepressants, eluxadoline, lubiprostone, and linaclotide. Loperamide, cholestyramine and osmotic laxatives are not recommended for overall IBS symptoms. The nature of the IBS symptoms (diarrhea-predominant or constipation-predominant) should be considered in the choice of pharmacological treatments. Conclusions Patients with IBS may benefit from a multipronged, individualized approach to treatment, including dietary modifications, psychological and pharmacological therapies.

Objectives:Critical illness can have a significant psychological impact on patients and their families. To inform the design of a larger trial, we assessed feasibility of ICU diaries and psychoeducation to prevent posttraumatic stress disorder, depression, and anxiety following ICU stays.Design:Four

Background The mental health response to the coronavirus (COVID‐19) pandemic–related product shortages in those living with chronic gastrointestinal (GI) disorders has received little attention. We aimed to explore the association between the pandemic‐related product shortages and psychological distress in people with GI disorders. Methods This online cross‐sectional survey was nested within an ongoing, international, prospective study of well‐being in people with GI disorders. The study was advertised in multiple countries in May‐September 2020 via patient organizations and social media. The primary outcome measure was distress, evaluated by the Depression Anxiety Stress Scale. We utilized linear regressions, adjusting for covariates and testing individual moderation effects. Key Results Overall, 831 people completed the survey from 27 countries, of whom 82% were female (mean age = 49 years). The most common disorders included inflammatory bowel disease (n = 322), celiac disease (n = 273), and irritable bowel syndrome (n = 260). Significant problems accessing food were reported by 19.8%, non‐medical therapies by 16%, toilet paper by 10.8%, and essential medication by 8.9% of the sample (>5% pain medication). There was a positive association between toilet paper and pain medication shortages and distress, and a negative association between food shortages and distress. Significant moderation effects were identified for COVID‐19 prevalence and toilet paper and food shortages, and between COVID‐19 fear and pain medication shortages. Conclusions and Inferences The study documented a significant relationship between product shortages and psychological distress, which were associated with COVID‐19 prevalence and fear. Strategies addressing COVID‐19 fear could potentially modify the relationship between shortages and distress., Product shortages were associated with psychological distress in people with gastrointestinal disorders at the time of the COVID‐19 pandemic. The relationship between product shortages and distress was moderated by COVID‐19 prevalence and fear.

The aim of this cross-sectional study was to use an extended common sense model (CSM) to evaluate the impact of fear of COVID-19 on quality of life (QoL) in an international inflammatory bowel disease cohort. An online study involving 319 adults (75% female, mean (SD) 14.06 (15.57) years of symptoms) completed the Gastrointestinal Symptom Rating Scale, Brief Illness Perceptions Questionnaire, Fear of Contracting COVID-19 Scale, Brief-COPE, Depression, Anxiety and Stress Scale, and the EUROHIS-QOL. The extended CSM had an excellent fit (χ2 (9) = 17.06, p = .05, χ2/N = 1.90, RMSEA = 0.05, SRMR = 0.04, CFI = .99, TLI = .97, GFI = 0.99), indicating the influence of gastrointestinal symptoms on QoL was mediated by illness perceptions, fear of COVID-19, adaptive and maladaptive coping, and psychological distress. Interventions targeting the fear of COVID-19 in the context of an individual's perceptions will likely enhance QoL during the pandemic.

Brackground We aimed to examine associations between elevated symptoms of depression and anxiety and disease activity in inflammatory bowel disease (IBD). Previous findings have been inconsistent and have not accounted for variability in the courses of these conditions over time. Methods We followed 247 participants with IBD (153 Crohn’s disease [CD], 94 ulcerative colitis [UC]) for 3 years. Annually, participants underwent an abdominal examination, reported therapies used for IBD, and completed the Hospital Anxiety and Depression Scale (HADS) questionnaire. We evaluated associations of elevated symptoms (scores ≥11) of anxiety (HADS-A) and depression (HADS-D) with the presence of active IBD as measured using the Powell Tuck Index for UC and the Harvey-Bradshaw Disease Activity Index for CD. We employed logistic regression with generalized estimating equations, simultaneously estimating between-person and within-person effects. Results Of 247 participants, 15 (6.1%) had elevated symptoms of depression (HADS-D ≥11) at enrollment, 41 (16.6%) had elevated symptoms of anxiety (HADS-A ≥11), and 101 (40.9%) had active IBD. On average, individuals with elevated symptoms of depression (odds ratio [OR], 6.27; 95% CI, 1.39–28.2) and anxiety (OR, 2.17; 95% CI, 1.01–4.66) had increased odds of active IBD. Within individuals, elevations in symptoms of depression over time were associated with increased odds of active IBD (OR, 2.70; 95% CI, 1.15–6.34), but elevated symptoms of anxiety were not. After adjustment for covariates (including disease activity), elevated symptoms of depression were also associated with increased odds of biologic therapy use (OR, 2.02; 95% CI, 1.02–4.00). Conclusion Symptoms of depression and anxiety are associated with disease activity in IBD over time. Reducing these symptoms should be incorporated into the management of IBD.

BACKGROUND & AIMS: Patients with celiac disease (CD) often report inadvertent gluten exposures and challenges reading labels. The most common cause of non-responsive CD is gluten exposure. We aimed to assess whether recently diagnosed CD patients can determine whether a food is gluten-free based on labeling, and to assess skills over time. A secondary aim was to identify factors associated with label reading proficiency. METHODS: Inception cohort with follow-up at 6, 12, and 24 months after diagnosis. Participants were asked to determine whether 25 food items were gluten-free based on labeling information. Diet adherence was assessed using the Celiac Diet Assessment Tool (CDAT) and the Gluten-Free Eating Assessment Tool (GF-EAT). 144 adults with newly diagnosed celiac disease were enrolled. The initial quiz at 6 months was completed by 83%. Quizzes were completed by 72% at 12 months and 70% at 24 months. RESULTS: Median overall accuracy scores were: 23/25, 24/25 and 21/25 at 6, 12 and 24 months respectively. Gluten-free products with explicit “gluten-free” claims had the fewest errors. Quiz scores were not correlated with tTG IgA levels, or CDAT or GF-EAT scores. Diet adherence was generally good (>85% with CDAT

Introduction We aimed to validate the Medication Adherence Report Scale-5 (MARS-5) as a tool for assessing medication adherence in inflammatory bowel disease (IBD) and to determine predictors of medication adherence. Methods One hundred twelve (N = 112) adults with confirmed IBD participating in the longitudinal Manitoba Living With IBD Study were eligible. Demographics, IBD type, surgeries, disease activity (using the Inflammatory Bowel Disease Symptom Inventory and fecal calprotectin levels), perceived stress, and medication use were collected biweekly through online surveys. The MARS-5 scores were obtained at baseline and at 1 year. Correlation between medication monitoring data and MARS-5 scores was performed and the optimal MARS-5 cutoff point for adherence assessment determined. Predictors of medication adherence were assessed at both ≥90% and ≥80%. Results Participants were predominantly female (71.4%), mean age was 42.9 (SD = 12.8), and the majority (67.9%) had Crohn disease (CD). Almost half (46.4%) were taking more than 1 IBD medication, with thiopurines (41.9%) and biologics (36.6%) the most common. Only 17.9% (n = 20) were nonadherent at a 22 and >23, respectively. Having CD (OR = 4.62; 95% confidence interval, 1.36-15.7) was the only significant predictor of adherence. Conclusion MARS-5 is a useful measure to evaluate adherence in an IBD population. In this highly adherent sample, disease type (CD) was the only predictor of medication adherence.

Background Celiac disease (CD) is a common chronic gastrointestinal illness with a range of manifestations. The only available treatment is strict gluten avoidance, therefore patients are effectively self-managed. Despite the critical role patients play in their treatment, patient perspectives on long-term CD care have not been formally assessed and are therefore not represented in current clinical guidelines. Aims To determine the opinions of CD patients on the need for long-term CD follow-up, the utility of various aspects of CD follow-up, and the areas in which further information is desired. Methods The Manitoba Celiac Disease Cohort includes newly diagnosed adults with elevated TTG and/or EMA antibodies and Marsh III histology. At the 24-month follow-up visit, participants were asked to rate the utility of various aspects of CD care from 1–5 (low-high) and their desire for further information on CD-related issues from 1–6 (low-high). Results A total of 213 patients were recruited and 137 participants completed the online survey (median age 41 [interquartile range 29–57] years; 68% female). Adherence to a gluten free diet was variable, with 29% of patients having TTG antibodies above the upper limit of normal. Two-thirds of participants felt they should be seen regularly for their celiac disease, while 79.8% of those who wished to be followed felt they should be seen every 6–12 months. Blood tests were the most highly rated component of CD care (scored ≥4 by 78% of respondents). Celiac symptom review, information on research in celiac disease, and the opportunity to ask questions about vitamins and supplements were also positively regarded. Diet review was not generally considered helpful. 79% of patients desired further information on research in CD, while approximately 60% desired information on the long-term complications of CD and the risk of nutritional deficiencies. Conclusions The majority of CD patients find regular specialist follow-up helpful, particularly for biochemical assessment of disease activity and its complications. Further information on CD research and the long-term complications of CD should be addressed in follow-up visits. These aspects of follow-up care should be reflected in future guidelines.

Background We aimed to investigate (1) the stability of inflammatory aspects of diet over 1 year among persons with inflammatory bowel disease (IBD) and (2) the impact of change in diet on changes in inflammation and IBD symptoms over 1 year. Methods Participants were recruited to the Manitoba Living with IBD Study and completed the Harvard Food Frequency Questionnaire (FFQ). The Dietary Inflammatory Index (DII) and the Empirical Dietary Inflammatory Index (EDII) were used to calculate the inflammatory potential of the diet. Inflammation was measured by fecal calprotectin (≥250 µg/g). Symptoms were measured by the IBD Symptom Inventory (IBDSI). All measures were obtained at baseline and 1 year. Dietary Inflammatory Index and Empirical Dietary Inflammatory Index scores >0 and Results One hundred thirty-five participants (66% CD) were included. Approximately one third of the variance in EDII (36%) and DII (33%) scores was explained by changes in diet over time. Each unit increase in the change in EDII (baseline to follow-up) was associated with a greater odds of FCAL, indicating active inflammation (>250 µg/g; odds ratio, 3.1; 95% confidence interval [CI], 1.02–9.93; P = 0.04) and with a rise in IBDSI of 6.7 (95% CI, 1.0–12.4; P = 0.022; theoretical IBDSI range, 0–81). There was no association between changes in DII and changes in FCAL or IBDSI. Conclusion The EDII, but not the DII, may have utility to identify the inflammatory potential of diet. This inflammatory potential can contribute to inflammation and/or disease symptoms in persons with IBD.

We conducted a systematic review and a fixed-effects meta-analysis to determine whether incident adverse psychiatric events (APE) including depression, anxiety, psychosis, or suicide were associated with biologic therapy in IBD. Six randomized controlled trials and a cohort study met criteria, reporting an incidence of APE in 4,882 patients. The risk difference per 100 person-months of any APE with a biologic medication was 0.01 (95% confidence interval = 0.00–0.02). There was insufficient evidence available in randomized controlled trials to conclude that biologic therapy in IBD is associated with an increased incidence of APE., Lay Summary We conducted a systematic review to determine whether adverse psychiatric events (APE) were associated with biologic therapy in IBD. In the seven studies, meeting search criteria biologic therapy in IBD was not associated with an increased incidence of APE.

Background Substance use disorders (SUDs) impose a substantial individual and societal burden; however, the prevalence and associated factors in persons with inflammatory bowel disease (IBD) are largely unknown. We evaluated the prevalence and risk factors of SUD in an IBD cohort. Methods Inflammatory bowel disease participants (n = 247) were recruited via hospital- and community-based gastroenterology clinics, a population-based IBD research registry, and primary care providers as part of a larger cohort study of psychiatric comorbidity in immune-mediated inflammatory diseases. The Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders IV was administered to participants to identify lifetime SUD, anxiety disorder, and major depressive disorder. Additional questionnaires regarding participants’ sociodemographic and clinical characteristics were also completed. We examined demographic and clinical factors associated with lifetime SUD using unadjusted and adjusted logistic regression modeling. Results Forty-one (16.6%) IBD participants met the criteria for a lifetime diagnosis of an SUD. Factors associated with elevated odds of SUD were ever smoking (adjusted odds ratio [aOR], 2.96; 95% confidence interval [CI], 1.17–7.50), male sex (aOR, 2.44; 95% CI, 1.11–5.36), lifetime anxiety disorder (aOR, 2.41; 95% CI, 1.08–5.37), and higher pain impact (aOR, 1.08; 95% CI, 1.01–1.16). Conclusions One in six persons with IBD experienced an SUD, suggesting that clinicians should maintain high index of suspicion regarding possible SUD, and inquiries about substance use should be a part of care for IBD patients, particularly for men, smokers, and patients with anxiety disorders and pain., Authors evaluated the prevalence and risk factors of SUD in an IBD cohort (n = 247). Forty-one (16.6%) participants experienced a lifetime SUD. Factors associated with elevated odds of SUD were ever smoking, male sex, lifetime anxiety disorder, and higher pain impact.

Background Suicide is a leading cause of death worldwide. Transition from suicidal ideation (SI) to suicide attempt is high within a year of SI onset. The risk of suicide and SI is elevated in persons with inflammatory bowel disease (IBD) versus the general population. We aimed to validate the Patient Heath Questionnaire (PHQ)-9 as a screening tool for SI in IBD and to determine factors associated with SI in IBD. Methods IBD participants (n = 247) recruited from the community and clinics completed the PHQ-9 and participated in the Structured Clinical Interview for DSM-IV (SCID). We determined the sensitivity, specificity, and positive and negative predictive value (PPV and NPV) of the PHQ-9 in identifying SI as compared to the SCID. Using logistic regression we examined the association of SI with demographic and clinical factors. Results SI was endorsed by 24 (9.7%) participants on the PHQ-9 and 5 (2.0%) based on the SCID. The PHQ-9 had good sensitivity (100%), specificity (92.2%), and NPV (100%) but low PPV (20.8%) for SI. On univariate analysis, factors strongly associated with SI were depression (OR 13.1; 95%CI: 4.46, 40.5), anxiety (OR 11.3; 95%CI: 4.46, 28.6), and active disease (OR 3.87; 95%CI: 1.54, 9.71). On multivariable analysis, depression (OR 5.54; 95%CI: 1.67, 18.4) and pain (OR 1.14; 95%CI: 1.03, 1.25) were associated with SI. Conclusions Overall the PHQ-9 is a valid screening tool for SI in IBD patients, and routine implementation of this tool would support screening for depression and SI effectively and efficiently in clinical practice.

Background Few studies have evaluated the association between comorbidities associated with increased vascular risk and brain volume changes in multiple sclerosis (MS). To date, findings have not been consistent with respect to which comorbidities are associated with lower brain volumes or whether comorbidities associated with increased vascular risk are associated with greater brain volume loss over time. Objectives We aimed to evaluate the association between the Framingham Risk Score (FRS) which evaluates vascular risk and normalized whole brain volume in MS. Methods We included 98 participants with MS who underwent two brain MRIs two years apart, from which whole brain volumes were calculated. Each participant reported their comorbidities and medications taken. Blood pressure, height and weight were recorded and we calculated the FRS. We tested the association between the FRS at baseline and brain volume at the second time point using quantile regression adjusting for baseline normalized brain volume, age, gender and use of disease-modifying therapy. Results As the FRS increased, brain volume was lower, both at enrollment (β= -0.24; 95%CI: -0.42, -0.04) and at follow-up (-0.27; 95%CI: -0.45, -0.08). After further adjustment for age, gender, and use of disease modifying therapy, higher FRS remained associated with lower brain volume at follow-up at the 90th percentile of brain volume (β= -2.22; 95%CI: -3.40, -1.04) but not at the 10th or 50th percentiles. Conclusion Higher FRS were associated with lower brain volumes in persons with MS at baseline, and with brain volume loss over time. This effect was most pronounced for persons with higher brain volumes at baseline, which suggests that prevention, detection and effective management of comorbidities associated with vascular risk in people with MS is particularly important early in the disease course.

Celiac disease and functional intestinal disorders may overlap, yet the natural history of functional symptoms in patients with celiac disease is unknown. To investigate the prevalence of irritable bowel syndrome (IBS), functional dyspepsia (FD), and functional bloating (FB) symptoms among patients with celiac disease at diagnosis and during the first year of a gluten-free diet. Adults with a new diagnosis of celiac disease were surveyed at baseline, 6 months and 1 year using standardized measures for intestinal symptoms [Rome III diagnostic questionnaire and celiac symptom index (CSI)] and gluten-free diet adherence [gluten-free eating assessment tool (GF-EAT) and celiac diet adherence test]. At diagnosis, two-thirds fulfilled Rome III diagnostic questionnaire symptom criteria for IBS (52%), functional dyspepsia (27%), and/or functional bloating (9%). One year post-diagnosis, there was high adherence to a gluten-free diet as 93% reported gluten exposure less than once per month on the GF-EAT and only 8% had ongoing celiac disease symptoms (CSI score >45). The rates of those meeting IBS (22%) and functional dyspepsia (8%) symptom criteria both decreased significantly on a gluten-free diet. The prevalence of functional symptoms (any of IBS, FD or FB) at 1 year was 47%. Long-term follow-up of patients with celiac disease is necessary because many patients with celiac disease who are adherent to a gluten-free diet have persistent gastrointestinal symptoms.

Background Our aim was to explore the relationships among perceived stress, intestinal inflammation, and inflammatory bowel disease (IBD) symptoms over time. Methods Participants were recruited from a population-based registry of persons with IBD and assessed at months 0, 3, and 6. Key dependent measures were the Manitoba IBD Index (symptom activity), Cohen's Perceived Stress Scale, and fecal calprotectin in stool (intestinal inflammation). Results Complete data were available for 417 participants at months 0; 369 provided follow-up data. Active symptoms were reported by 54% of those with Crohn's disease (CD) and 40% of those with ulcerative colitis (UC) and approximately one-third consistently had fecal calprotectin measures ≥250 μg/g, suggestive of active inflammation. A significant proportion of participants had indications of inflammation but no active symptoms over the 6 months. Correlations of month 0 perceived stress and disease activity measures with values at months 3 and 6 for both CD and UC indicated strong temporal stability. In hierarchical multiple regression analyses, month 0 symptom activity was thus a strong predictor of later symptom activity for CD and UC. Perceived stress predicted change in symptom activity from 0 to 3 months for CD, as did use of prednisone for UC. Comparably, month 0 perceived stress was a strong predictor of later perceived stress for CD and UC, while month 0 symptom activity predicted change in perceived stress from 0 to 3 months for both CD and UC. Conclusions The analysis revealed prospective bidirectional relationships between perceived stress and IBD symptoms but no relationship between perceived stress and change in intestinal inflammation as assessed by fecal calprotectin.

Supplemental digital content is available in the text., Background Psychiatric comorbidities, such as depression and anxiety, are very common in persons with rheumatoid arthritis (RA) and can lead to adverse outcomes. By appropriately treating these comorbidities, disease-specific outcomes and quality of life may be improved. Objective The aim of this study was to systematically review the literature from controlled trials of treatments for depression and anxiety in persons with RA. Methods We searched multiple online databases from inception until March 25, 2015, without restrictions on language, date, or location of publication. We included controlled trials conducted in persons with RA and depression or anxiety. Two independent reviewers extracted information including trial and participant characteristics. The standardized mean differences (SMDs) of depression or anxiety scores at postassessment were pooled between treatment and comparison groups, stratified by active versus inactive comparators. Results From 1291 unique abstracts, we included 8 RA trials of depression interventions (6 pharmacological, 1 psychological, 1 both). Pharmacological interventions for depression with inactive comparators (n = 3 trials, 143 participants) did not reduce depressive symptoms (SMD, −0.21; 95% confidence interval [CI], −1.27 to 0.85), although interventions with active comparators (n = 3 trials, 190 participants) did improve depressive symptoms (SMD, −0.79; 95% CI, −1.34 to −0.25). The single psychological trial of depression treatment in RA did not improve depressive symptoms (SMD, −0.44; 95% CI, −0.96 to 0.08). Seven of the trials had an unclear risk of bias. Conclusions Few trials examining interventions for depression or anxiety in adults with RA exist, and the level of evidence is low to moderate because of the risk of bias and small number of trials.
