- INTRODUCTION: Psychological alterations are common and considered important for symptom generation in irritable bowel syndrome (IBS). However, the possible cumulative effect of having multiple psychological alterations on gastrointestinal (GI) symptom severity in IBS is largely unknown. METHODS: Patients with IBS (Rome IV) completed validated questionnaires assessing GI symptoms (Gastrointestinal Symptom Rating Scale, IBS version and IBS Severity Scoring System), personality traits (Big Five), posttraumatic stress and psychological alterations, anxiety (Generalized Anxiety Disorder 7-item scale and State-Trait Anxiety Inventory), depression (Patient Health Questionnaire, 9-item version), fatigue (Multidimensional Fatigue Inventory), pain catastrophizing, somatization (Patient Health Questionnaire, 12-item version), stress (Perceived Stress Scale), and GI-specific anxiety (Visceral Sensitivity Index). Of the 18 possible psychological factors, those with significant associations with GI symptom severity, corrected for multiple comparisons, were identified. The associations between increasing number of psychological alterations (validated cutoff values or uppermost tertile) and the severity of GI symptoms were analyzed with linear trend analyses. RESULTS: In total, 106 patients with IBS (Rome IV criteria) were included (72 [68%] women, median age of 35 [interquartile range: 26-45] years). Psychological alterations were common and overlap among these factors were frequently seen. Five psychological factors (physical fatigue, GI-specific anxiety, perceived stress, pain catastrophizing, and trait anxiety) demonstrated significant, noncollinear associations with GI symptom severity. With increasing number of these psychological alterations, a gradual increase was seen in the overall severity of GI symptoms (Gastrointestinal Symptom Rating Scale, IBS version: partial eta(2) = 0.268, P < 0.001; IBS Severity Scoring System: partial eta(2) = 0.219, P < 0.001, both large effect sizes). DISCUSSION: Distinct associations were seen between the severity of GI symptoms and individual, as well as an increasing number of psychological alterations. This highlights the importance of understanding different psychological alterations for the disease burden in IBS (visual abstract, Supplementary Digital Content 1, http://links.lww.com/AJG/B756).

- Objectives: The aim of this study was to determine the occurrence of GI symptoms in adults with celiac disease (CD) treated with a gluten-free diet for several years. Methods: We studied a cohort of adults with CD (n = 51; 59% women) aged 45–64 yr and proved to be in remission after 8–12 yr of treatment. They were examined by the GI Symptom Rating Scale, which comprises five syndromes: indigestion, diarrhea, constipation, abdominal pain, and reflux. A general population sample (n = 182; 57% women) of same age served as controls. Results: Subjects with CD reported significantly more GI symptoms than the general population sample, as assessed by the GI Symptom Rating Scale total score (p < 0.01). This was particularly true for women with CD who scored worse than female controls for all syndromes on the GI Symptom Rating Scale. By contrast, the men with CD reported no more symptoms than male controls. The women with CD showed generally more complaints than the men with CD did, notably within indigestion, constipation, and abdominal pain, corresponding to a 2-fold higher rate of GI symptoms (60%vs 29%; p < 0.04). Conclusion: Adult CD patients on a gluten-free diet for several years experienced significantly more GI symptoms than the general population sample. This may have some of its origin in the composition of a gluten-free diet. The symptoms were more pronounced in the women. This may raise questions of an association with their subjective health status, which has been shown to be lower than in men with CD.

- OBJECTIVES: Collagenous colitis is increasingly recognized as a common diarrheal disorder of inflammatory origin. Intestinal inflammation is generally associated with increased mucosal permeability, but little is known about barrier function in microscopic colitis. Our aim was to investigate the mucosal barrier to nonpathogenic bacteria in collagenous colitis. METHODS: The study included 33 individuals, 25 with collagenous colitis (14 in clinical remission, 11 with active disease, and 8 of these again after 6 weeks budesonide treatment) and 8 control patients. Bowel movements were registered for 1 week. Endoscopic biopsies from the sigmoid colon were mounted in modified Ussing chambers and assessed for short-circuit current (I-sc), transepithelial resistance (TER), and transmucosal passage of chemically killed Escherichia coli K12. RESULTS: Bacterial uptake was increased in patients in remission, 1.6 U (1.1-3.0) and in those with active disease, 4.6 U (2.5-5.8; median (IQR)), compared to controls, 0.7 U (0.1-1.1; P=0.004 and P=0.001, respectively). Active disease also had significant decrease in transepithelial resistance (TER) after 120 min, -9.7 Omega cm(2) ((-13)-(-4.3)), compared to controls, -5.2 Omega cm(2) ((-7.2)-(-3.1)), P=0.03; or patients in remission, -4.8 Omega cm(2) ((-8.0)-(-1.2)), P=0.04. Budesonide decreased median stool frequency to 1.9 (1.3-2.2) compared to 3.8 (3.7-4.2) before treatment (P=0.01), but bacterial uptake was still increased after budesonide 2.9 U (1.5-3.8), (P=0.006 compared to controls), and there were no significant changes in histology. CONCLUSIONS: Collagenous colitis presents with significantly increased uptake and altered mucosal reactivity to nonpathogenic bacteria. Budesonide induces clinical remission and restores mucosal reactivity but does not abolish the increased bacterial uptake. An underlying barrier dysfunction may explain the frequent and rapid relapses in CC.

- OBJECTIVES: Ulcerative colitis (UC) is a chronic inflammatory disease usually responding well to anti-inflammatory drugs but many patients will still need colectomy. Appendectomy is associated with a lower risk of later developing UC. We aimed to assess the longitudinal relationship between appendectomy, appendicitis, and disease course in UC patients. METHODS: A national cohort of UC patients with a diagnosis in 1964-2010 was identified from the Swedish National Patient Register that also provided information regarding appendicitis and/or appendectomy before or after the UC diagnosis. The risk for colectomy and UC-related hospital admissions was evaluated. RESULTS: Among 63,711 UC patients, 2,143 had appendectomy and 7,690 underwent colectomy. Appendectomy for appendicitis before 20 years of age and for non-appendicitis at all ages before UC diagnosis was associated with a lower risk of colectomy (hazard ratio (HR) 0.44, 0.27-0.72 and HR 0.62, 0.43-0.90, respectively), and fewer hospital admissions (incidence rate ratio (IRR) 0.68, 95% confidence interval (CI) 0.64-0.73 and IRR 0.54, 0.47-0.63, respectively). Appendectomy for appendicitis after the UC diagnosis was associated with a higher risk of colectomy (HR 1.56, 1.20-2.03), whereas no such association was found for other pathology (HR 1.40, 0.79-2.47). CONCLUSIONS: Appendectomy early in life and before developing UC is associated with a lower risk of colectomy as well as UC-related hospital admissions. Appendectomy for appendicitis after established UC appears associated with a worse disease course, with an increased rate of subsequent colectomy.

- INTRODUCTION: To determine the risk of inflammatory bowel disease (IBD) in patients with celiac disease (CeD) (and vice versa ) compared with general-population comparators. METHODS: Using Swedish histopathology and healthcare register data, we identified 48,551 patients with CeD and 83,529 with IBD diagnosed in 1969-2016. Each patient was compared with age- and sex-matched general-population comparators (CeD: n = 240,136; IBD: n = 408,195). Cox regression estimated hazard ratios (HRs) for IBD in patients with CeD and vice versa . Our main analyses were limited to events beyond the first year of follow-up to reduce potential surveillance bias. RESULTS: During follow-up, 784 (1.6%) patients with CeD were diagnosed with IBD compared with 1,015 (0.4%) matched comparators. In patients with CeD, the HR for IBD was 3.91 (95% confidence interval [CI] 3.56-4.31), with largely similar HRs for Crohn's disease (4.36; 3.72-5.11) and ulcerative colitis (3.40; 3.00-3.85). During follow-up, 644 (0.8%) patients with IBD and 597 (0.1%) comparators were diagnosed with CeD. The HR for CeD in patients with IBD was 5.49 (95% CI 4.90-6.16), with the highest risk estimates seen in ulcerative colitis (HR = 6.99; 6.07-8.05), and the HR for Crohn's disease was 3.31 (2.69-4.06). In patients with CeD and IBD, the diagnostic interval was usually <1 year; however, HRs of 3-4 were seen even after 10 years of follow-up. During 20 years of follow-up, 2.5% of patients with CeD developed incident IBD, and 1.3% of patients with IBD developed CeD. DISCUSSION: The bidirectional association between CeD diagnosis and IBD warrants attention in the initial assessment and follow-up of these conditions. Their co-occurrence, independent of temporal sequence, suggests shared etiology. Copyright © 2022 by The American College of Gastroenterology.
